Linux sucks.
Now now, chill. I'm using it as my main OS for a few years now. I know what I'm talking and this title is a bit click-baity, but this just has to go out there:
1. It's usable as a Windows replacement just fine - FALSE. XFCE4 is years old and buggy as hell especially on multi-monitor set-up, Gnome3 gets stuck more often than my Windows 98 machine used to, KDE is like a rich kid on meth. Plug in Bluetooth headphones? Well no, sorry, you have to research that online, since you'll probably need to install some packages for it to work. Did I say "work"? Well no, because after more research you realize that Debian on Gnome3 on gdm3 launches pulseaudio on its own, so you have 2 instances of pulseaudio, and one of them is stealing your headphones sometimes and you either have no sound or shitty sound. How do I know that you ask? The same way I know everything else - every time you try to do something new on any Linux, it involves a ton of research. Exciting research, don't get me wrong, but at this point it looks more like a toy than a reliable desktop computer operating system.
2. And why am I using pulseaudio? Why not alsa? years ago people were discussing on forums that pulseaudio is old and dead, yet here we are with new LTS release of Ubuntu still shining with Pulseaudio. How about several different service management systems being deprecated by new ones, each having different configurations and calling methods? Apparently systemd is old and lame now. It's a mix of 10 year old software that works badly, with a 5 year old replacement that works worse, somehow trying to live under the same roof. Does it work? Ask my headphones who sound like a fucking dial-up modem.
3. Let's talk about displays, shall we? xorg is old and deprecated, right? We got Wayland that's mostly stable. Don't know what that is? That's just basic knowledge for Linux. And when you try to install network-manager, it also tries to install Mir toolkits. Because why the fuck not install 3 display managers when you want a network manager, of which one is old and dying, one is young and stupid, and another is an infant that died of cancer?
4. Want to integrate with Google Drive? Yeah, there's a tool that mounts the drive as a local directory. Yeah only for Ubuntu. Want it on Debian? You need to compile it. Oh wait, it's on Ocaml, because fuck mainstream languages, we're hipsters. How do you compile Ocaml? Well you need to have Ocaml on your system, dummy. How do you do that? Well you need to compile Ocaml. Ok, how do I do that? Well, git clone, download and install some dependencies, configure, make... oh sorry, you're using libssl1.0.2g when you need libssl1.0.1f, nope, sorry, won't work. Want to install libssl1.0.1f? Why? You already have the "g", stupid! Want to remove libssl1.0.2g? Bye-bye literally everything that you have on your PC. But at least you got the "f". Does it work now? Well no, because you need libssl1.0.2g for another dependency to work.
And all I ever wanted was to get a fucking document from google drive (not nudes, I promise).
5. Want to watch a movie? Let me tear that screen in half and make the bottom half late by a couple of frames, because who needs vertical sync, right? Oh you do? Well install the native drivers maybe. Oh you have? Welcome to eternal Boot to Recovery mode, motherfucka!
---------------------------------
Yeah, most of the times things work just fine. But the reason I know what those things are and how they work is not curiosity. The reason that I know the inner workings of Linux much better than the inner workings of Windows, is because in those few years that I've been using it full time, it has caused me 10 times more headache than I have ever experienced with other systems. And it's not the usual annoyances like "OMG it rebooted when I didn't ask it to", but more like "Oh, it won't work and I need 2 days to find out why" kind of stuff, because even if you experience the same thing again, it's always caused by some new shit and the old solution won't work any more.
I still love it, and will continue to use it. I don't know why really. Maybe because I'm not afraid of fucking it up any more? Maybe because I can do what I want in it and recovering will be easier than on Windows?
It's a toy for me, after all these years. And I also use it for professional reasons.
But whenever someone presents it as a better alternative to Windows, I just want to puke.51 -
Was lead developer at a small startup, I was hiring and had a budget to add 3 new people to my team to develop a new product for the company.
Some context first and then the rant!
Candidate 1 - Amazing, a dev I worked with before who was under utilized at the previous company. Still a junior, but, she was a quick learner and eager to expand her knowledge, never an issue.
Candidate 2 - Kickass dev with back end skills and extras, he was always eager to work a bit more than what was expected. I use to send him home early to annoy him. haha!
Candidate 3 - Lets call him P.
In the interview he answers every question perfectly, he asks all the right questions and suggests some things I havent even thought of. CTO goes ahead and says we should skip the technical test and just hire the guy, his smart and knows what his talking about, I agree and we hire him. (We where a bit desperate at this stage as well.)
He comes in a week early to pick up his work laptop to get setup before he starts the next week, awesome! This guy is going to be an asset to the company, cant wait to have him join the team - The CTO at this stage is getting ready to leave the company and I will be taking over the division and need someone to take over lead position, he seems like the guys to do it.
The guys starts the next week, he comes in and the laptop we gave him is now a local server for testing and he will be working off his own laptop, no issue, we are small so needed a testing stack, but wasnt really needed since we had procedures in place for this already.
Here is where everything goes wrong!!! First day goes great... Next day he gets in early 6:30am (Nice! NO!), he absolutely smells, no stinks, of weed, not a light smell, the entire fucking office smells of weed! (I have no problem with weed, just dont make it my problem to deal with). I get called by boss and told to sort this out people are complaining! I drive to office and have a meeting with him, he says its all good he understands. (This was Friday).
Monday comes around - Get a call from Boss at 7:30am. Whole office smells like weed, please talk to P again, this cannot happen again. I drive to office again, and he again says it wont happen again, he has some issues with back pain and the weed helps.
Tuesday - Same fucking thing! And now he doesnt want to sign for the laptop("server") that was given to him, and has moved to code in the boardroom, WHERE OUR FUCKING CLIENTS WILL BE VIEWING A DEMO THAT DAY OF THE PRODUCT!! Now that whole room smells like weed, FML!
Wednesday - We send P a formal letter that he is under probation, P calls me to have a meeting. In the meeting he blames me for not understanding "new age" medicine, I ask for his doctors prescription and ask why he didnt tell me this in the interview so I could make arrangements, we dont care if you are stoned, just do good work and be considerate to your co-workers. P cant provide these and keeps ranting, I suggest he takes pain killers, he has none of it only "new age" medicine for him.
Thursday - I ask him to rather "work" from home till we can get this sorted, he comes in for code reviews for 2 weeks. I can clearly see he has no idea how the system works but is trying, I thought I will dive deeper and look at all of his code. Its a mess, nothing makes sense and 50% of it is hard coded (We are building a decentralized API for huge data sets so this makes no sense).
Friday - In code review I confront him about this, he has excuses for everything, I start asking him harder questions about the project and to explain what we are building - he goes quiet and quits on the spot with a shitty apology.
From what I could make out he was really smart when it came to theory but interpreting the theory to actual practice wasnt possible for him, probably would have been easier if he wasnt high all the time.
I hate interview code tests, but learned a valuable lesson that day! Always test for some code knowledge as well even if you hate doing it, ask the right questions and be careful who you hire! You can only bullshit for so long in coding before someone figures out that you are a fraud.16 -
Happened a few weeks ago but still awesome.
Me and a good friend have a website together but we don't monitor it too much.
He studied with me in the same class but went towards frontend/apps where I chose backend/servers/security. He knows how to do basic Linux stuff but that's about it.
We were at a party when he noticed that our site was offline. Walked over to me (because I manage the server) to notify me so I could look into it said I'd look into it (phone):
*visits site: nothing*
*online dig tool: got the server ip*
*remembered this one didn't have pubkey authentication - after three passwords attempts I'm in*
"service apache2 status"
*service doesn't exist*
*right, migrated this one from Apache to nginx....*
"history"
*ah, an nginx restart probably suffices...*
"service nginx restart"
BAM, site is reachable again.
*god damnit, lets encrypt cert expired...*
"history"
*sees command with certbot and our domain both in one*
"!892"
*20 seconds later: success message*
*service nginx reload*
BAM, site works securely again.
"Yo mate, check the site again"
Mate: 😶 w-w-what? *checks site and his watch* you started less than two minutes ago...?
Me: yeah..?
Mate: 😶 now this is why YOU manage our server and I don't 😐
His face was fucking gold. It wasn't that difficult for me (I do this daily) but to him, I was a God at that moment.
Awesome moment 😊24 -
My most awkward recruiter interaction?
Just graduated college and got 'suckered' by an programming position ad that turned out to be a recruiting company. It was fine since they charge the company for their services and not me.
After a couple of weeks of waiting (they initially promised I would/could have at least 3 interviews a week, which hadn't happened.) I decided to start looking again on my own, found a position, and I was hired.
About two months later I get a phone call:
<skipping the pleasantries>
R: "I see you are working for D, congratulations. I've started the paperwork for our reimbursement."
Me: "Reimburse for what? I found that job on my own."
R: "D is one of the companies we work with and when we submitted your resume, they told us you were already hired."
Me: "And?"
R: "And you signed a contract and now its time to pay. The fees only start at $500"
Me: "Not me. I have the contract, it states, in the second paragraph, I am not responsible for any hiring fees."
<couple of seconds of silence>
R: "Yes, but that is only if we negotiated the contact. Since you went behind our back, we couldn't start the process"
Me: "And?"
R: "And its a breach of contract."
Me: "I'm not a lawyer, I don't understand what you're saying. It says right here on the contract I signed, I don't pay any fees. No where does it say I'm not allowed to look for a job on my own. Right?"
R: "Um..yea..right..right...but you were hired by one of our contracted companies."
Me: "No way I would have known that. Maybe you should have set up an interview long before now."
<R is getting pretty angry at this point>
R: "I'm sure we gave you list of companies we work with. Contacting those companies is a breach of contract. Unless you want our lawyers to get involved, the fee is only $500. Failing to honor your side of the agreement and we'll be forced to contact your employer and begin garnishing your wage until the fee is paid. You don't want that, do you?"
Me: "There was no list and I am allowed to find a job on my own. Again, I'm not responsible for you not setting up an interview so do whatever you think you can do. Have a good night"
<I hang up>
About a week later..
Boss: "Got a phone call from XYZ Recruiting requesting a wage garnishment. Do you know anything about that?"
<I explain the situation>
Boss: "Oh good grief. We've worked with them a couple of times and we contact them on an individual basis for new hires. You're fine"
Me: "You're not going to garnish my paycheck?"
Boss: "No no no, that's not how this works. He was probably trying to scare you into paying their crazy fees."
Me: "What if they get their lawyers involved? I don't want to cause any trouble"
Boss: "Ha ha...XYZ Recruiting is a couple of guys in an office and we have lawyers on the 3rd floor who eat and breath this shit. They know that and you won't hearing from them again."5 -
For people who think/find that open source solutions are always better than commercial/paid/proprietary ones, you are not going to like this rant.
I'm starting to get really fucking fed up with people always, whenever I see someone (including myself) mentioning that an open source solution which is an alternative to a closed source one, saying that it's shit.
I've had countless encounters on here (also irl) where someone mentions that an open source solution (GIMP or Libre Office for example) is shit by default while they've maybe (or probably?) not even used it themselves.
Also people going "you can't even compare those two as for what they can do/features/functions". I'm definitely not saying that those open solutions are perfect. But to call them worthless or shit and/or to say that you literally 'cannot compare them' or that the open solution just doesn't work as a *FACT* is fucking bullshit.
Let's take GIMP for example, the use case of a friend of mine:
- He works both with macOS and Linux Mint, he *needs* a design/photo editing tool which is cross platform. (or at least one which works on macOS+Linux)
- He does not mind paying for software but he prefers to use software which is free as in freedom because he also likes to tinker with the software (a lot of people find this argument bullshit, I noticed on here. Why is that? It's a valid reason. Maybe not for you but we're not talking about you right now).
- He likes Photoshop but due to Linux incompatibility and the fact that he can't tinker around with the code, it's not an option for him.
- He'd gladly go for paid software but GIMP fills all his design/photo editing needs (also the more advanced ones but don't ask them to me because I have no fucking clue how that shit works)
- GIMP *just works* for him, he never has trouble with it.
Let's take Libre Office, my own use case:
- It *NEEDS* to work on Linux, which Libre does.
- It *HAS* to be open source, ethic/moral thingy; Libre Office is open source.
- It doesn't need to work complete magic but it needs proper basic document and 'excel' sheet functionalities which is the case with Libre and it works *for me*.
- I don't mind paying for it, will probably donate in the future (seeding the macOS+windows+linux versions fulltime at the moment)
See, for our use cases, it works very well. So why go into "it's no match for proprietary alternatives" mode right away? It actually is, as you see in the examples above.
Please stop saying that those solutions *don't work* or *are shit* because they do work and are useful for me and loads of people around the world.
Do they have *ALL* the features which their proprietary alternatives have? Maybe, maybe not, maybe they're missing some and maybe they even have some features which the proprietary alternatives don't have, I haven't checked out every feature.
I'm not saying that it works for you, for the record, I'm just saying that just because for you it is a fact that they're bad/shit/hardly working, doesn't mean they are for others.21 -
Always makes me laugh that if you don’t have a Mac you clearly aren’t a proper web developer to most people 😂 (I used to use Mac but switched)
Me: *Pulls out my windows laptop to do some web development work*
Friend: How can you use that to develop with, you’re supposed to use a Mac everyone knows that. What do you even code in?
Me: I write everything in word and then transfer it to a Mac to test as obviously the internet only works on Mac.
Friend: oh right .. that makes sense, probably easier just to buy a Mac though isn’t it?
Me: ....
Time to get a new friend 😩5 -
Every step of this project has added another six hurdles. I thought it would be easy, and estimated it at two days to give myself a day off. But instead it's ridiculous. I'm also feeling burned out, depressed (work stress, etc.), and exhausted since I'm taking care of a 3 week old. It has not been fun. :<
I've been trying to get the Google Sheets API working (in Ruby). It's for a shared sales/tracking spreadsheet between two companies.
The documentation for it is almost entirely for Python and Java. The Ruby "quickstart" sample code works, but it's only for 3-legged auth (meaning user auth), but I need it for 2-legged auth (server auth with non-expiring credentials). Took awhile to figure out that variant even existed.
After a bit of digging, I discovered I needed to create a service account. This isn't the most straightforward thing, and setting it up honestly reminds me of setting up AWS, just with less risk of suddenly and surprisingly becoming a broke hobo by selecting confusing option #27 instead of #88.
I set up a new google project, tied it to my company's account (I think?), and then set up a service account for it, with probably the right permissions.
After downloading its creds, figuring out how to actually use them took another few hours. Did I mention there's no Ruby documentation for this? There's plenty of Python and Java example code, but since they use very different implementations, it's almost pointless to read them. At best they give me a vague idea of what my next step might be.
I ended up reading through the code of google's auth gem instead because I couldn't find anything useful online. Maybe it's actually there and the past several days have been one of those weeks where nothing ever works? idk :/
But anyway. I read through their code, and while it's actually not awful, it has some odd organization and a few very peculiar param names. Figuring out what data to pass, and how said data gets used requires some file-hopping. e.g. `json_data_io` wants a file handle, not the data itself. This is going to cause me headaches later since the data will be in the database, not the filesystem. I guess I can write a monkeypatch? or fork their gem? :/
But I digress. I finally manged to set everything up, fix the bugs with my code, and I'm ready to see what `service.create_spreadsheet()` returns. (now that it has positively valid and correctly-implemented authentication! Finally! Woo!)
I open the console... set up the auth... and give it a try.
... six seconds pass ...
... another two seconds pass ...
... annnd I get a lovely "unauthorized" response.

I had to open the desktop app to write this because I could never write a rant this long on the app.
This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.
Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.
[START RANT]
"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."
From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table
The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.
The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:
array[index]
Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.
Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:
a = {1, 5, 9};
a["hello_world"] = "whatever";
a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.
This is the difference between indexing and lookups. But you may say,
"Algo! If I do this:
a = {"first", "second", "third"};
print(a[1]);
...then "first" appears in my console!"
Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:
Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):
el = arr + (sz * i)
This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.
That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.13 -
3 rants for the price of 1, isn't that a great deal!
1. HP, you braindead fucking morons!!!
So recently I disassembled this HP laptop of mine to unfuck it at the hardware level. Some issues with the hinge that I had to solve. So I had to disassemble not only the bottom of the laptop but also the display panel itself. Turns out that HP - being the certified enganeers they are - made the following fuckups, with probably many more that I didn't even notice yet.
- They used fucking glue to ensure that the bottom of the display frame stays connected to the panel. Cheap solution to what should've been "MAKE A FUCKING DECENT FRAME?!" but a royal pain in the ass to disassemble. Luckily I was careful and didn't damage the panel, but the chance of that happening was most certainly nonzero.
- They connected the ribbon cables for the keyboard in such a way that you have to reach all the way into the spacing between the keyboard and the motherboard to connect the bloody things. And some extra spacing on the ribbon cables to enable servicing with some room for actually connecting the bloody things easily.. as Carlos Mantos would say it - M-m-M, nonoNO!!!
- Oh and let's not forget an old flaw that I noticed ages ago in this turd. The CPU goes straight to 70°C during boot-up but turning on the fan.. again, M-m-M, nonoNO!!! Let's just get the bloody thing to overheat, freeze completely and force the user to power cycle the machine, right? That's gonna be a great way to make them satisfied, RIGHT?! NO MOTHERFUCKERS, AND I WILL DISCONNECT THE DATA LINES OF THIS FUCKING THING TO MAKE IT SPIN ALL THE TIME, AS IT SHOULD!!! Certified fucking braindead abominations of engineers!!!
Oh and not only that, this laptop is outperformed by a Raspberry Pi 3B in performance, thermals, price and product quality.. A FUCKING SINGLE BOARD COMPUTER!!! Isn't that a great joke. Someone here mentioned earlier that HP and Acer seem to have been competing for a long time to make the shittiest products possible, and boy they fucking do. If there's anything that makes both of those shitcompanies remarkable, that'd be it.
2. If I want to conduct a pentest, I don't want to have to relearn the bloody tool!
Recently I did a Burp Suite test to see how the devRant web app logs in, but due to my Burp Suite being the community edition, I couldn't save it. Fucking amazing, thanks PortSwigger! And I couldn't recreate the results anymore due to what I think is a change in the web app. But I'll get back to that later.
So I fired up bettercap (which works at lower network layers and can conduct ARP poisoning and DNS cache poisoning) with the intent to ARP poison my phone and get the results straight from the devRant Android app. I haven't used this tool since around 2017 due to the fact that I kinda lost interest in offensive security. When I fired it up again a few days ago in my PTbox (which is a VM somewhere else on the network) and today again in my newly recovered HP laptop, I noticed that both hosts now have an updated version of bettercap, in which the options completely changed. It's now got different command-line switches and some interactive mode. Needless to say, I have no idea how to use this bloody thing anymore and don't feel like learning it all over again for a single test. Maybe this is why users often dislike changes to the UI, and why some sysadmins refrain from updating their servers? When you have users of any kind, you should at all times honor their installations, give them time to change their individual configurations - tell them that they should! - in other words give them a grace time, and allow for backwards compatibility for as long as feasible.
3. devRant web app!!
As mentioned earlier I tried to scrape the web app's login flow with Burp Suite but every time that I try to log in with its proxy enabled, it doesn't open the login form but instead just makes a GET request to /feed/top/month?login=1 without ever allowing me to actually log in. This happens in both Chromium and Firefox, in Windows and Arch Linux. Clearly this is a change to the web app, and a very undesirable one. Especially considering that the login flow for the API isn't documented anywhere as far as I know.
So, can this update to the web app be rolled back, merged back to an older version of that login flow or can I at least know how I'm supposed to log in to this API in order to be able to start developing my own client?6 -
only developer with linux. everyone else are on windows.
constantly finding myself in following conversation
me : "something is not working for me on the web page i am writing"
jim : "let me see just a.... WOW! WHAT IS THIS?"
me:"ubuntu"
jim:"wat?"
me:"linux"
jim:"well... " +sigh + "that's your problem right there! this works to everyone else. and they're on windows. why would you ever not use windows?"
me:"have you ever tried anythig else?"
jim:"never needed to. windows works just fine.."
me:"well... does your computer ever freeze?"
jim:"constantly"
me:"that doesn't happen on ubuntu. at least it is quite rare"
jim:"nah... you're mistaken. windows rocks! anyway, you should probably talk to someone who knows ubuntu cause my chrome works just fine so it must be this ubuntu of yours.."14 -
Background: I'm not drunk yet, BUT I'M WORKING ON IT.
okay.
I just finished a second sprint on my React app. The first was to build a merchant onboarding flow. The second was to do substantial cleanup as I learned more about react/redux, and to create a "supply order" flow -- basically purchasing marketing materials and services. I finished that in a week, and I'm pretty proud. api-guy wanted it done in a day. i laughed. he probably could have, but it would have been a copy of the code in a new repo with some lines changed.
ANYWAY. it's all done and It's super pretty and works amazingly well. It has both the onboarding flow and the ordering flow, with a nice pop-out sidebar for navigation, namespaced actions, etc. Everything is pretty clean. I even added a cart to the ordering (despite everyone telling me not to) because wtf, what if someone wants to order TWO items? dumbasses. So I made that. it's sexy.
Anyway, it's all done and shiny and fancy and wonderful and I'd *love* to share screenshots if only it didn't give away where I worked. :<
... but the point of the rant!
After the first sprint, I made a copy of the repo so I could rework it and add more functionality without touching the original. (Hey! That's what a branch is for, right? Why didn't I branch it up?
well, read on)
I knew we were going to have multiple separate flows for this app: onboard, ordering, merchant tools, admin tools, support, etc. So, I wrote its server portion (the webpack builder + http server) so it would serve the same app at whatever url the user hit, and set a cookie containing that host+url. This allows the app to serve different content (basically showing/hiding content) based on the URL and future login roles. If someone hits /order, it would hide everything but the order flow. If they're a merchant, it would show all the merchant views plus ordering, etc.
tl;dr This way I can use the same codebase for multiple sites, drastically simplifying development, branding, and what have you. This new app could obv also be a drop-in replacement for the original onboarding project because of the above.
HOWEVER. this apparently isn't good enough for api-guy. He's terrified that adding/updating future components will affect all the existing content somehow.
so.
now we have three repos for basically the same codebase. 1) onboard aka "surfboard", 2) ordering, 3) merchant tools, aka "ferrari" (the "future" app).
Except.
1) "surfboard" is a very old version of the code. 3) "ferrari" is also old, since 2) "ordering" has newer content in it now.
... and somehow this is better?
fuck if i can figure out how.
His reasoning is "well, you won't be touching surfboard or ordering for 6 months, so now you don't have to worry about it." Sure, except, you know, it'll be a pain in the ass in 6 months now when I have a crapton of code and branding to redo. ffs.
Oh. We also have three Heroku pipelines for these three repos. for the same codebase.
and now you know why i'm drinking.undefined idiocy fucking hell fuck this noise api guy i'm just gonna replace everything later this codebase is as dry as the friggin ocean7 -
I'm going for longest rant. TL:DR; version here:

Twat Client,
As per our conversation, here is an invoice for the work you requested on behalf of U.S. Bloom. I realize that you ended up going with another designer, but you did request samples of what my take on the logo design would be. The following line item is indicative of 1 hour of graphic design consultation as per your request via Skype.
As I recall, you mentioned that this is not how Upwork "works" but considering it was you who requested that I converse with you via Skype instead of via the Upwork messenger, and since there were no clear instructions on how to proceed with Upwork after our initial consultation, It is assumed that you were foregoing Upwork altogether to work with me directly, thus the invoice from me directly for my time involved in the project. I would have reached out to you via Skype, but it seems that you may have severed our connection there.
After spending a little time researching your company, I could not find current information for Basic Media Marketing, but I was able to reach out to your former partner Not A. Twat, who was more than helpful and suggested that he would encourage you to pay for the services rendered.
It is discouraging that you asked for my help and I delivered, but when I ask for compensation in return for my skills, you refused to pay and have now taken your site offline and removed me as a contact from Skype.
{[CLIENT of CLIENT]},
I am sorry that I have bothered you with this email. I copied you on it merely for transparency's sake. I am sure that your logo is great and I am sure whatever decision was made is awesome for your decision. I just wanted to make sure that you weren't getting "samples" of other people's work passed off as original work by Twat Media Marketing.
I can't speak for any of the other candidates, but since Twat asked me to conduct work with him via Skype rather than through Upwork, and since he's pretty much a ghost online now, (Site Offline, LinkedIn Removed or Blocked, and now Skype blocked as well) one has to think this was a hit and run to either crowdsource your logo inexpensively or pass off other artist's work as his own. That may not be the case, but from my perspective all signs are pointing to that scenario.
Here is a transcript. Some of his messages have been redacted.
As you can clearly see, requests and edits to the logo were being made from Jon to me, but he thinks it's a joke when I ask about invoicing and tries to pass it off as an interview. Do you see any interview questions in there? There were no questions about how long I have been designing, what are my rates, who have I done work for in the past, or examples of my previous work. There were none because he didn't need them at this point.
He'd already seen my proposal and my Behance.net portfolio as well as my rates on Upwork.com. This was a cut to the chase request for my ideas for your logo. It was not just ideas, but mock designs with criticism and approval awaiting. Not only that, but I only asked for an hour of compensation. After looking at the timestamps on our conversation, you can clearly see that I spent at least 3 hours corresponding with Twat on this project. That's three hours of work I could have spent on an honest paying customer.
I trust that TWATCLIENT will do the right thing. I just wanted you guys to know that I was in it to do the best design I could for you. I didn't know I was in it to waste three hours of my life in an "interview" I wasn't aware I was participating in.
Reply from ClientClient:
Hello Sir,
This message is very confusing?
We do not owe your company any money and have never worked with you before.
Therefore, I am going to disregard that invoice.
Reply from TWATCLIENT's boss via phone:
I have two problems with this. One I don't think your business practices are ethical, especially calling MY client directly and sending them an invoice.
Two why didn't you call or email Jon before copying my client on the email invoice?
Me: Probably because he's purposely avoiding me and I had no way to find him. I only got his email address today and that was from a WHOIS lookup.
Really, you don't think my business practices are ethical? What about slavery? Is that ethical? Is it ethical to pass of my designs to your client for critique, but not pay me for doing them?
... I'LL HAVE TO CALL YOU BACK!

!!office drama
I haven't been around much in recent weeks. Due to family illness, christmas shopping, dealing with estranged parents, and brooding over the foregoing, I haven't had a lot of time or energy left to myself.
tl;dr: The CTO ("API Guy") is ostensibly getting fired, and I might be taking over his job. I don't know if I should accept, try to stave this off, or simply flee.
------
Anyone who has been following my recent rants knows that API Guy is my boss, and he often writes terrible code. It's solid and unbreakable, but reading it is a *nightmare.* One of our applications is half the length of Leo Tolstoy's War and Peace, and it's difficult to tell what code is live and what amounts to ancient, still-active landmines. This is one application; we have several, most of which I've never even looked at.
Ostensibly the code is so terrible because the company grew extremely quickly, and API Guy needed to cram in lots of unexpected / planned-against features. From what I can see, that seems about right, but I haven't checked timeframes [because that's a lot of work!].
Here's a brief rundown of the situation.
- API Guy co-founded the company with the CEO.
- CEO and API Guy have been friends for a long time.
- CEO belives the company will fail with API Guy as head of tech.
- They could just be testing me; I have zero way of knowing. API Guy seems totally oblivious, and CEO seems sincere, so this feels pretty doubtful.
- CEO likes pushing people around. CEO believes he can push me around. API Guy doesn't budge. (I probably won't, either, except to change task priorities.)
- API Guy's code is huge and awful, but functional.
- API Guy is trying to clean up the mess; CEO doesn't understand (maybe doesn't care).
- Literally nobody else knows how the code works.
- Apart from API Guy and myself, the entire company is extroverted sales people.
- None of these sales people particularly like me.
- Sales people sell and sell and sell without asking development if they can pull enough magic features out of their hat to meet the arbitrary saleslines. (because the answer is usually no)
- If I accept, I would be the sole developer (at first) and responsible for someone else's mountain of nightmarish code, and still responsible for layering on new features at the same pace as he. Pay raise likely, but not guaranteed.
- My getting the position is contingent upon the CEO and the investors, meaning it's by no means guaranteed.
- If I don't accept, likely API Guy will be replaced with someone else of unknown ability, who doesn't know the code, and whom I must answer to regardless. Potentially OK, potentially a monumental disaster.
Honestly, it feels like I'm going to be screwed no matter what course I choose.
Perhaps accepting is slightly better?
The best would be to assume the position of CTO and keep API Guy around -- but that would feel like an insult to him. I doubt he'd be okay with it. But maybe. Who knows? I doubt the CEO would seriously consider that anyway.
I feel like a lamb between a dim, angry rhino, and an oblivious one.23 -
DISCLAIMER: UNPOPULAR OPINION
I'm tired of the Linux community, they effectively discourage me of taking part in any discussion online
I'm currently making Windows-only soft, some game stuff, some legacy DirectX stuff you got it.
Everytime I go online, this shitty pattern happens, when I stumble upon a problem in project I don't know how to fix and I ask for help
These are responses
- HA, HA, WINDOWS BAD, HA, HA, GET REAL SYSTEM
- In Linux, we can do X too. I mean it has 4x less functionality and way shittier UX and is even harder to implement but it can probably work on too Linux, so it's better, yes, just move to Linux
- btw you didn't like Linux before? Try this distro man, it's better <links random distro>
Is there anything valuable in the Linux community? I feel like these people don't like Linux anyway, they just hate Windows. Every opinion, tip is always opinion based. Anyone who works on internals knows how much better and how well thought is Windows kernel compared to Linux kernel. Also, if someone unironically uses Linux distro on desktop PC then he's a masochist because desktop Linux is dieing. So many distros ceased work only this year.
Is it a good tool for servers and docker containers? I don't have my head stuck up my ass to admit that yes, it's much better than Windows here.
This community got me stressed right now, I fear that when I go to bathroom or open my microwave there's gonna be a Linux distro recommendation there

But why.. why do you need to be told that twice? Oh ffs, fuck it.
Reminds me of robocopy. That shit required me to tell it 25 times what to do and it'd still not do it right as well. And you know what, compared to rsync where -avz works 99% of the time, I hate it.7 -
Hacktoberfest time, and I usually try to contribute by creating some trivial issues and labelling them as such - ones that I could fix in 2 seconds, just to help those starting out get a pull request and get used to how the process works. Like, we're talking *really* trivial - remove superfluous import statements, that sort of thing. In most of these I list exactly what needs to be changed.
This guy picks, what's probably the *easiest* of these tasks going, and then comes back saying he's got some questions. Dude, seriously?! It's right there in the damn issue description.
Whatever, I decide to be nice and I say he's welcome to ask. Brace myself for answering some stupid crap, but fine, we were all new once.
THE GUY COMES BACK AND SAYS HE NEEDS A CALL. A call, seriously? What is this crap? I do you a favour by letting you create a trivial PR, and you want me to literally burn my time & jump on a call to take you through step by step what to do?! Pff, and people wonder why I'm grumpy most of the time.11 -
I am much too tired to go into details, probably because I left the office at 11:15pm, but I finally finished a feature. It doesn't even sound like a particularly large or complicated feature. It sounds like a simple, 1-2 day feature until you look at it closely.
It took me an entire fucking week. and all the while I was coaching a junior dev who had just picked up Rails and was building something very similar.
It's the model, controller, and UI for creating a parent object along with 0-n child objects, with default children suggestions, a fancy ui including the ability to dynamically add/remove children via buttons. and have the entire happy family save nicely and atomically on the backend. Plus a detailed-but-simple listing for non-technicals including some absolutely nontrivial css acrobatics.
After getting about 90% of everything built and working and beautiful, I learned that Rails does quite a bit of this for you, through `accepts_nested_params_for :collection`. But that requires very specific form input namespacing, and building that out correctly is flipping difficult. It's not like I could find good examples anywhere, either. I looked for hours. I finally found a rails tutorial vide linked from a comment on a SO answer from five years ago, and mashed its oversimplified and dated examples with the newer documentation, and worked around the issues that of course arose from that disasterous paring.
like.
I needed to store a template of the child object markup somewhere, yeah? The video had me trying to store all of the markup in a `data-fields=" "` attrib. wth? I tried storing it as a string and injecting it into javascript, but that didn't work either. parsing errors! yay! good job, you two.
So I ended up storing the markup (rendered from a rails partial) in an html comment of all things, and pulling the markup out of the comment and gsubbing its IDs on document load. This has the annoying effect of preventing me from using html comments in that partial (not that i really use them anyway, but.)
Just.
Every step of the way on building this was another mountain climb.
* singular vs plural naming and routing, and named routes. and dealing with issues arising from existing incorrect pluralization.
* reverse polymorphic relation (child -> x parent)
* The testing suite is incompatible with the new rails6. There is no fix. None. I checked. Nope. Not happening.
* Rails6 randomly and constantly crashes and/or caches random things (including arbitrary code changes) in development mode (and only development mode) when working with multiple databases.
* nested form builders
* styling a fucking checkbox
* Making that checkbox (rather, its label and container div) into a sexy animated slider
* passing data and locals to and between partials
* misleading documentation
* building the partials to be self-contained and reusable
* coercing form builders into namespacing nested html inputs the way Rails expects
* input namespacing redux, now with nested form builders too!
* Figuring out how to generate markup for an empty child when I'm no longer rendering the children myself
* Figuring out where the fuck to put the blank child template markup so it's accessible, has the right namespacing, and is not submitted with everything else
* Figuring out how the fuck to read an html comment with JS
* nested strong params
* nested strong params
* nested fucking strong params
* caching parsed children's data on parent when the whole thing is bloody atomic.
* Converting datetimes from/to milliseconds on save/load
* CSS and bootstrap collisions
* CSS and bootstrap stupidity
* Reinventing the entire multi-child / nested params / atomic creating/updating/deleting feature on my own before discovering Rails can do that for you.
Just.
I am so glad it's working.
I don't even feel relieved. I just feel exhausted.
But it's done.
finally.
and it's done well. It's all self-contained and reusable, it's easy to read, has separate styling and reusable partials, etc. It's a two line copy/paste drop-in for any other model that needs it. Two lines and it just works, and even tells you if you screwed up.
I'm incredibly proud of everything that went into this.
But mostly I'm just incredibly tired.
Time for some well-deserved sleep.7 -
In january 2023 i was contacted by a recruiter offering me a job position.
I DID NOT ASK FOR A JOB.
I WAS NOT LOOKING FOR A JOB.
THEY contacted ME.
Ok. So i went along with it and see how it goes. They probably wont hire me nor would i give a shit. Chatted with this recruiter for a while. She forgets to answer my message for 5 fucking days. Twice. Once because she was doing God knows what and the second time because she was on paid vacation. Fine i don't give a shit about you at all anyways.
So this recruiter chatting has been stretched out for several days. I think over a WEEK. So she forwarded me to their lead developer.
I applied to work as a full stack java spring boot backend + angular frontend engineer.
So:
- java backend
- angular frontend
- full stack
- shitload of devops
- shitload of projects i built
- worked with clients
- have CS degree, graduated
- worked a job at their rival company
What could go fucking wrong with all of these stats right?
During technical + hr interview (3 of us on google meets) they asked me what salary I'd be comfortable with.
I said $1500/month straight out.
keep in mind:
- In my country $500 or $600 is a salary for engineers per month
- You get a raise of +$150 which is around $750 after working for 1+ year
- You can earn $1000+ after you work for +2 years
- Rent here is $200-300 a month at minimun. And because of inflation its just getting worse especially with food. So this salary is not for living but for survival.
Their lead engineer gave me a WHOLE ASS FUCKING PROJECT TO BUILD and i had to code it within 10 days. Great so at least 17+ days of my fucking life to waste on these fucktards who contacted ME.
The project was about building a web app coffee shop literally what mcdonalds has when you order via those tablets. I had to build this in java spring boot and angular. I had to integrate:
- docker, devops
- barmen, baristas, orders
- people can order at the table or to go
- each barista can take 5 orders at a time
- each coffee has different types of fields and brewing time
- each barman brews each coffee different period of time
- barista cant take more than 5 orders for to go until barman finishes the previous order
- barista can take more than 5 orders but if those orders were ordered from table, and they have to be put in queue
- had to build CRUD admin functionality coffee's
- had to export them all of the postman routes
- had to design a scalable database infrastructure for all of this alone
- shitload of stuff more
And guess what. After 10 painful days I BUILT THE WHOLE THING MYSELF AND I BUILT EVERYTHING THEY ASKED FOR. IT WAS WORKING.
Submitted it. They told me they'll contact me within 7 days to schedule the final Technical interview after they review what i built. Great so another 17+7 days of my fucking time wasted.
OH and they also told me to send them THE WHOLE GITHUB REPOSITORY AND TRANSFER OWNERSHIP TO THEIR COMPANY'S OWNERSHIP. once you do this you cant have your repository back. WTF? WHY CANT YOU JUST REVIEW THE CODE FROM MY PUBLIC REPOSITORY? That was so weird but what can i fucking do argue with these dickheads?
After a week of them not answering i contacted them via email. They forgot and apologized. Smh. Then they scheduled an interview within 3 days. Great more of my time wasted.
During interview i was on a google meets with their lead engineer, 1 backend java spring boot engineer and 1 angular frontend developer. They were milking me dry for 1 whole fucking hour.
They only pointed out the flaws in what i built, which are miniscule and have not once congratulated me on the rest of the good parts. I explained them i had to rush those parts so the code may not be perfect. I had other shit to do in my life and not work for your shitty project for $0/hour for 10 days you fucking dickriders.
So they quickly ran over to theory. They asked me where is jwt token stored. Who generates it. How the backend knows to authenticate user by it. I explained.
What are solid principles. I said i cant explain what is it but i understand how it works, why its needed and how to implement it (they can clearly see in the project i just build that i applied SOLID principles everywhere) - but i do admit i dont know the theory behind it 100% clearly.
Then they asked me about observables and promises in angular. I explained them how they work and how subscribe method is used (as they can clearly see that i used it in the code). Then they asked me to explain them under the hood of how observables work. The fuck? I dont know and dont care? But i can learn it as i work there?
Etc
Final result: after dragging this for 1 fucking month for miserable $1500/month they told me: we can either hire you now but for a much lower salary which you probably wont be happy with, or you can study more these things we discussed "and know why the car leaks oil" and reapply back to us in 2-3 months!23 -
It works.
How I hate that sentence.
Whenever that sentence pops up, I wanna take a frying pan, make some bacon, eat the bacon and slam the still hot pan with grease through someone's face till the skull breaks.
Why has he so many anger issues, one might ask.
Usually the sentence "It works" means that after looking at "working thing" it works wrong in 95 % of all cases, but hey - for 5 % it at least does *something* right. Not everything, don't get ya hope up.
We had this fun topic happening again today and I'm still too angry to sleep.
Lucene analysis of texts in Elasticsearch.
Stopword list? Multiple word n-grams per line, duplicates, not lower cased, not properly encoded.
Tokenizers? Duh. Why should one put them in proper order.... Or more realistic: There is an order in tokenizers necessary *devs with shocked faces*.
Language specific details... UHM. Wait. Languages are different? There are edge cases in languages? *more shocked faces*.
Even more shocking that if an text processing pipeline is implemented horribly wrong, it delivers wrong results. *mind blown*.
But our unit tests (this goes out to @kiki) were working.
Yeah. You dumb nuggets who even an amoeba would be ashamed of, when you only do positive tests in unit tests with the most obvious working examples, then your unit tests are just useless waste of nibbles.
Some of the devs are really a fucking waste of genetic information, should have probably ended better in a sock.
If this sounds too harsh, they had 2 weeks.
In just 3 hours I found out that they can redo that with supervision.
-.-
I'm getting too old for that shit. Seriously.4 -
I've recently received another invitation to Google's Foobar challenges.
A while ago someone here on devRant (which I believe works at Google, and whose support I deeply appreciate) sent me a couple of links to it too. Unfortunately back then I didn't take the time to learn the programming languages (Python or Java) that Google requires for these challenges. This time I'm putting everything on Python, as it's the easiest language to learn when coming from Bash.
But at the end of the day.. I am a sysadmin, not a developer. I don't know a single thing about either of these languages. Yet I can't take these challenges as the sysadmin I am. Instead, I have to learn a new language which chances are I'll never need again outside of some HR dickhead's interview with lateral thinking questions and whiteboard programming, probably prohibited from using Google search like every sane programmer and/or sysadmin would for practical challenges that actually occur in real life.
I don't want to do that. Google is a once in a lifetime opportunity, I get that. Many people would probably even steal that foobar link from me if they could. But I don't think that for me it's the right thing to do. Google has made a serious difference by actually challenging developers with practical scenarios, and that's vastly superior to whatever a HR person at any other company could cobble together for an interview. But there's one thing that they don't seem to realize. A company like Google consists of more than just developers. Not only that, it probably consists - even within their developer circles - of more than just Python and Java developers. If any company would know about languages that are more optimized such as C, it would be Google that has to leverage this performance in order to be able to deliver their services.
I'll be frank here. Foobar has its own issues that I don't like. But if Google were a nice company, I'd go for it all the way nonetheless - after all, they are arguably the single biggest tech company in the world, and the tech industry itself is one of the biggest ones in the world nowadays. It's safe to say that there's likely no opportunity like working at Google. But I don't think it's the right thing. Even if I did know Python or Java... Even if I did. I don't like Google's business decisions.
I've recently flashed my OnePlus 6T with LineageOS. It's now completely Google-free, except for a stock Yalp account (that I'm too afraid to replace with my actual Google account because oh dear, third-party app stores, oh dear that could damage our business and has to be made highly illegal!1!). My contacts on that phone are are all gone. They're all stored on a Google server somewhere (except for some like @linuxxx' that I consciously stored on device storage and thus lost a while back), waiting for me to log back in and sync them back. I've never asked for this. If Google explicitly told me that they'd sync all my contacts to my Google account and offer feasible alternatives, I'd probably given more priority to building a CalDAV and CardDAV server of my own. Because I do have the skills and desire to maintain that myself. I don't want Google to do this for me.
Move fast and break things. I've even got a special Termux script on my home screen, aptly named Unfuck-Google-Play. Every other day I have to use it. Google Search. When I open it on my Nexus 6P, which was Google's foray into hardware and in which they failed quite spectacularly - I've even almost bent and killed it tonight, after cursing at that piece of shit every goddamn day - the Google app opens, I type some text into it.. and then it just jumps back to the beginning of whatever I was typing. A preloader of sorts. The app is a fucking web page parser, or heck probably even just an API parser. How does that in any way justify such shitty preloaders? How does that in any way justify such crappy performance on anything but the most recent flagships? I could go on about this all day... I used to run modern Linux on a 15 year old laptop, smoothly. So don't you Google tell me that a - probably trillion dollar - company can't do that shit right. When there's (commercialized) community projects like DuckDuckGo that do things a million times better than you do - yet they can't compete with you due to your shit being preloaded on every phone and tablet and impossible to remove without rooting - that you Google can't do that and a lot more. You've got fucking Google Assistant for fucks sake! Yet you can't make a decent search app - the goddamn thing that your company started with in the first place!?
I'm sorry. I'd love to work at Google and taste the diversity that this company has to offer. But there's *a lot* wrong with it at the business end too. That is something that - in that state - I don't think I want to contribute to, despite it being pretty much a lottery ticket that I've been fortunate enough to draw twice.
Maybe I should just start my own company.6 -
Im so frustrated with myself . I've always been afraid of being stupid . Perhaps it was because i was always called the "less intelligent" sibling by my parents . Well i did self-learn java , c++ and android (when i was 15) and made some apps and i did get acknowledged finally but i may have not acknowledged myself . I got into college a couple years ago and i can tell you right out that its like an island filled with stupidity. The teachers , the students. The other day i caught my teacher learning how a transistor works. This is unacceptable for someone who is teaching us advanced op-amps and other circuits . Well , I did get into this college cause it was less tedious and i thought college doesn't matter cause i can self-learn . All i needed was free time . Well college totally destroyed that too and provided no facilities in the process as well . So yeah should i blame my college for my inability to do things the past couple years. I mean i don't think i've learnt a single thing all this while. This is where my frustration begins cause i dont want to blame the college , it's not going to help me and i'll probably end up in a 9 to 5 call center job at this rate . Im also very heavily frustrated with myself , it's like everything i've done so far has been a path of least effort. I have tried a few things which were all just fads like machine learning and crypto and even trading . They felt good and thats what scares me , maybe i don't have the passion and am just looking for a quick buck . This is clearly reflected in the ideas i've been having as well . Well i've never had access to proper funds but now im just trying to justify this layman emotion . I just want to learn and be passionate about learning , researching and i just want enough funds for that . But im afraid , maybe its just that i want to feel superior than my circle . I mean i still don't know why i tried learning rust and wasted even more time setting up fedora and everything around it while i already had a working debian setup and a programming language i'm kind of versed with . i wouldn't say well cause im a self learner and i feel guilty for that . I definitely know i just learnt the surface of the language . Deep down i'm just another stupid fad obsessed guy who feels better by choosing a more complex language that my colleagues look upto . Is this what i am , if so im scared and i don't know what to do . People say that you are what you are and you cant change that . If i cant change this then i dont deserve this wasteful stupid life . I don't know what i should do and it makes me cry . Maybe acknowledging this would've helped but it hasn't , I've felt better playing fortnite rather than learning some basic electronics. Im another one of those aren't I ?17

iPhones are ridiculously picky when it comes to finding a mate- um charger. And knowing why doesn't really make it any easier to understand why. If anything it baffles me more.
So, let's start with appliances that are not phones. Think Bluetooth headsets, keyboards, earbuds, whatever. Those are simple devices. They see 5V on the VCC line and 0V on ground, and they will charge at whatever current they are meant to. Usually it will not exceed 200mA, and the USB 2.0 spec allows for up to 500mA from any USB outlet. So that's perfectly reasonable to be done without any fuss whatsoever.
Phones on the other hand are smarter.. some might say too smart for their own good. In this case I will only cover Android phones, because while they are smarter than they perhaps should be, they are still reasonable.
So if you connect an Android phone to the same 5V VCC and 0V ground, while leaving the data lines floating, the phone will charge at 500mA. This is exactly to be within USB 2.0 spec, as mentioned earlier. Without the data lines, the phone has no way to tell whether it *can* pull more, without *actually* trying to pull more (potentially frying a charger that's not rated for it). Now in an Android phone you can tell it to pull more, in a fairly straightforward way. You just short the data lines together, and the phone will recognize this as a simple charger that it can pull 1A from. Note that shorting data lines is not a bad thing, we do it all the time. It is just another term for making a connection between 2 points. Android does this right. Also note that shorted data lines cannot be used to send data. They are inherently pulled to the same voltage level, probably 0V but not sure.
And then the iPhones come in, Thinking Different. The iPhones require you to pull the data lines to some very specific voltage levels. And of course it's terribly documented because iSheep just trying to use their Apple original white nugget charger overseas and shit like that. I do not know which voltage levels they are (please let me know!), but it is certainly not a regular short. Now you connect the iPhone to, say, a laptop or something to charge. An Android phone would just charge while keeping data transmission disabled (because they can be left floating or shorted). This is for security reasons mostly, preventing e.g. a malicious computer from messing with it. An iPhone needs to be unlocked to just charge the damn thing. I'm fairly sure that that's because the data lines need to be pulled up, which could in theory enable a malicious computer to still get some information in or out of it. USB data transmission works at at least 200mV difference between the data lines. It could be more than that. So you need to unlock it.
Apple, how about you just short your goddamn data lines too like everyone else? And while you're at it, get rid of this Lightning connector. I get it, micro USB was too hard for your users. I guess they are blind pigs after all. But USB-C solved all of that and more. The only difference I can think of is that the Lightning connector can be a single board with pads on either side on the connector, while in USB-C that could be at the socket end (socket being less common to be replaced). And at the end of the day, that really doesn't matter with all the other things that will break first.
Think Different. Think Retarded. Such tiny batteries and you can't even fucking charge them properly.6 -
I haven't ranted for today, but I figured that I'd post a summary.
A public diary of sorts.. devRant is amazing, it even allows me to post the stuff that I'd otherwise put on a piece of paper and probably discard over time. And with keyboard support at that <3
Today has been a productive day for me. Laptop got restored with a "pacman -Syu" over a Bluetooth mobile data tethering from my phone, said phone got upgraded to an unofficial Android 9 (Pie) thanks to a comment from @undef, etc.
I've also made myself a reliable USB extension cord to be able to extend the 20-30cm USB-A male to USB-C male cord that Huawei delivered with my Nexus 6P. The USB-C to USB-C cord that allows for fast charging is unreliable.. ordered some USB-C plugs for that, in order to make some high power wire with that when they arrive.
So that plug I've made.. USB-A male to USB-A female, in which my short USB-C to USB-A wire can plug in. It's a 1M wire, with 18AWG wire for its power lines and 28AWG wires for its data lines. The 18AWG power lines can carry up to 10A of current, while the 28AWG lines can carry up to 1A. All wires were made into 1M pieces. These resulted in a very low impedance path for all of them, my multimeter measured no more than 200 milliohms across them, though I'll have to verify and finetune that on my oscilloscope with 4-wire measurement.
So the wire was good. Easy too, I just had to look up the pinout and replicate that on the male part.
That's where the rant part comes in.. in fact I've got quite uncomfortable with sentences that don't include at least one swear word at this point. All hail to devRant for allowing me to put them out there without guilt.. it changed my very mind <3
Microshaft WanBLowS.
I've tried to plug my DIY extension cord into it, and plugged my phone and some USB stick into it of which I've completely forgot the filesystem. Windows certainly doesn't support it.. turns out that it was LUKS. More about that later.
Windows returned that it didn't support either of them, due to "malfunctioning at the USB device". So I went ahead and plugged in my phone directly.. works without a problem. Then I went ahead and troubleshooted the wire I've just made with a multimeter, to check for shorts.. none at all.
At that point I suspected that WanBLowS was the issue, so I booted up my (at the time) problematic Arch laptop and did the exact same thing there, testing that USB stick and my phone there by plugging it through the extension wire. Shit just worked like that. The USB stick was a LUKS medium and apparently a clone of my SanDisk rootfs that I'm storing my Arch Linux on my laptop at at the time.. an unfinished migration project (SanDisk is unstable, my other DM sticks are quite stable). The USB stick consumed about 20mA so no big deal for any USB controller. The phone consumed about 500mA (which is standard USB 2.0 so no surprise) and worked fine as well.. although the HP laptop dropped the voltage to ~4.8V like that, unlike 5.1V which is nominal for USB. Still worked without a problem.
So clearly Windows is the problem here, and this provides me one more reason to hate that piece of shit OS. Windows lovers may say that it's an issue with my particular hardware, which maybe it is. I've done the Windows plugging solely through a USB 3.0 hub, which was plugged into a USB 3.0 port on the host. Now USB 3.0 is supposed to be able to carry up to 1A rather than 500mA, so I expect all the components in there to be beefier. I've also tested the hub as part of a review, and it can carry about 1A no problem, although it seems like its supply lines aren't shorted to VCC on the host, like a sensible hub would. Instead I suspect that it's going through the hub's controller.
Regardless, this is clearly a bad design. One of the USB data lines is biased to ~3.3V if memory serves me right, while the other is biased to 300mV. The latter could impose a problem.. but again, the current path was of a very low impedance of 200milliohms at most. Meanwhile the direct connection that omits the ~200ohm extension wire worked just fine. Even 300mV wouldn't degrade significantly over such a resistance. So this is most likely a Windows problem.
That aside, the extension cord works fine in Linux. So I've used that as a charging connection while upgrading my Arch laptop (which as you may know has internet issues at the time) over Bluetooth, through a shared BNEP connection (Bluetooth tethering) from my phone. Mobile data since I didn't set up my WiFi in this new Pie ROM yet. Worked fine, fixed my WiFi. Currently it's back in my network as my fully-fledged development host. So that way I'll be able to work again on @Floydian's LinkHub repository. My laptop's the only one who currently holds the private key for signing commits for git$(rm -rf ~/*)@nixmagic.com, hence why my development has been impeded. My tablet doesn't have them. Guess I'll commit somewhere tomorrow.
(looks like my rant is too long, continue in comments)3 -
TL;DR you suck, I suck and everybody sucks, deal with it....
------------------------------------
Let me let off some steam, since I've had enough of people hating on languages "just because"
Every language has it's drawbacks and quirks, BUT they have their strengths also. Saying "I hate {language}" is just you being and ignorant prick and probably your head is so far up your ass that you look like an ass hat. With that being said, every language is either good or bad depending on the developer writing in it. Let's give you an example:
If I ware to give you a brick and ask you to put a nail in a plank, can you do it? Yes, it will be easier if you do it with a hammer, but you have a brick, so hammer is out of the question. If you hit your thumb while doing it... well... sorry, but it is not the bricks fault - it is YOU!
JavaScript, yes it has a whole lot of problems, but it works, you can do a ton of stuff and does a good job at that, it is evolving through node and typescript (and others, just a personal pref), BUT if you used js when you ware debugging that jquery (1.0) plugin written in the free time of a 13 yo, who copy pasted a bunch from SO, well, it is not js' problem - deal with it. Same goes for PHP, i've been there where you had a single `index.php` with bazillion lines of code, did a bunch of eval and it was called MVC, but it also is evolving.. thing is all languages allow you to do some dumb stuff so YOU have to be responsible to not fuck it up (which you always DO btw, we all do). Difference is PHP/JS roll with it because the assumption is that you know what you are doing, which again - newsflash - you don't.
More or less I would blame that shit on businesses which decided to go with undergrads to save money instead of investing in their product, hell, I am in a major company that does not invest that doesn't care a whole lot about dev /tech stuff and now everybody's mother is an engineer - they care about money, because investors care about money (ROI) and because clean code does not pay the bills, but money does.
If we get all of the good practices and apply them to each language every one of them has it's place, that is why there is no "The Language", even if there was, we STILL ware going to fuck it up and probably it was going to be even worse than where we are now.
Study, improve, rinse and repeat... There are SENIORS and LEADS out there that are about 25-30 and have no fucking clue about the language, because they have stuck up their heads up the ass of frameworks and refuse to take a breath of clean air and consider something different than their dogmatic framework "way" of doing things.. That is the result you are seeing. Let me give you a fresh example to illustrate where I am at atm:
Le me works with ZendFramework 2.3-2.5 (why not, which is PHP5+ running on PHP7 [fancy, eh]), and little me writes a module for said project, and tries to contain it in its own space, i.e not touching anything outside of the folder of the module so it is SELF-CONTAINED (see, practices), during 2-3-4 iterations of code review, I've had to modify 4 different modules with `if (somthing === self::SOMETHING_TYPE)` as requested by my TL, which resulted in me not covering 3 use-cases after the changes and not adding a new event (the fw is event-driven, cuz.. reasons) so I have to use a bunch of ifs in the code, to check a config value and do shit. That is the way of I am asked to do things I hate what I've done and the fact that because of CR I have lost case-coverage, a week of work and the same TL will be on my ass on monday that things are now "perfect".
The biggest things is "we care about convention and code style"... right.... That is not because of the language, not because of me, not because of the framework - it is some dude's opinion that you hate, not the language.
New stuff are better, reinventing the wheel is also good, if it wasn't you would've had a few stone circular things on your car and things ware going to be like that - we need to try and try, that is the only way we actually learn shit.
Until things change in the trade, we will be on the same boat, complaining about the same shit over and over, you and me won't be alive probably but things will not change a bit.
We live in a place where state is considered good, god objects necessary (can you believe it, I've got kudos for using the term 'God Object'... yep, let that sink in). If you really hate something, please, oh god I beg you, show me how you will do it better and I will shake your hand and buy you a beer, but until then, please keep your ass-hurt fanboy opinion to your self, no one gives a shit about what you think, we will die and the world will not notice...6 -
How difficult is it to do things and do them properly? Clearly in 2019, very difficult. And why on Earth would you do things properly, when there's get rich quick schemes, shortcuts to be found and taken, and that filthy filthy legal tender. If the shitty implementation makes a profit, why do it properly? Makes no sense.
Except it fucking does. And you know why? Because of the guy that comes after you, that works with your fucking bullshit implementation and probably curses you to the moon and beyond in the process. Just like you probably did with the guy that came before you, with that bullshit you got tasked to work with. Don't be that guy. And don't be that guy to the next guy.
Still with me? Good. Here's the thing. You can do [insert job here] quick and dirty. But you're guaranteed to be checking back on it and fixing the crap later on. Or worse yet, someone else will be cursing you to the moon and beyond while they are fixing / working around your crap. So why not do it right in the first place? Is this why we can't have nice things?5 -
>>> Stadia thread <<<
Stadia is a new Cloud Gaming platform that runs on GCP and details were announced some minutes ago.
For maximum performance you would need at least 35mb/s, while about 10mb/s are enough for 720p l, Stereo gameplay.
Maximum performance provides 4k, HDR and 5.1 Surround Sound and comes in at 9,99$ / month for Stadia Pro. As far as announcements go, there are no lower performance tiers available.
Stadia Pro will get you unlimited access to your Games (I believe this is Bring-Your-Own-License, but I might be wrong), while Stadia Basic allows unlimited access to one specific game. For that you probably buy the game directly of Stadia, which then includes any fees in it's price.
Stadia will be usable on all devices that run Chrome and on the Chromecast Ultra. Android will get it's own app, first available on the Google Pixel 3, to be expanded later on, iOS was not mentioned.
Google developed a custom Stadia controller that works out of the box, including an Google Assistant and a DVR button. However, all other controllers should supported too, but I don't believe that's the case for playing on the Chromecast Ultra.
Starting now, you can get the Stadia Founders Edition, that allows you to be one of the firsts on the platform, includes a Controller, a Chromecast Ultra, 3 months of Stadia Pro, 3 additional months of Pro you can gift to your buddy and some Destiny Bundle with the first and second game, including all add-ons, plus the Destiny 2 Season pass.
The founders edition can be pre-ordered right now for about 129$.
Stadia launches 'later' this year, founders edition buyers will be the first to get public access on launch.8 -
Why me. Why is it always me who has issues with Windows. (The OS)
I HAVE to use windows for a specific thing right now. Fair enough, I have an old system lying around somewhere with not the best specs ever but it'll do. Windows 7, clean install.
Firstly, let's boot up! Booting goes fine, login goes well... "Installing device drivers" (keyboard and mouse combi). I connected this set a gazillion times before so no clue why windows would need to download the drivers YER AGAIN. But, fine, it works.
Let's connect a USB webcam and to to the hardware testing website to see if my setup is right!
(I mostly don't blame this part on windows)
The webcam drivers install successfully, good. Although the page says it isn't working, it displays the live cam footage well so whatever.
Installed Chrome (not chromium too badly) to see if it shows fine there but chrome doesn't detect ANY cam/mic combination at all, not even the integrated one(s).
Annoying so let's reboot and see if it works normally with all checks okay on Firefox.
Rebooted.... aaaaand the USB webcam driver installation fails. I'm weirded out since the drivers were installed BEFORE the reboot already. Firefox now does not display any can/mic.... until it does after a few reloads. Windows is still saying that the driver installation failed.
The testing webpage, however, still says its not working while I'm literally seeing my ugly smug on screen. I contact support which does a remote check and says all is good but there was probably "a glitch with Windows" while the checks are still mostly red, I take a copy of the chat log just to be sure.
Now, I kinda want to shut this system down until the time I'll need it but I'm rather afraid that Windows is going to throw driver conundrums yet again and I simply *CANNOT* have this right now. So, I'm leaving this system on until I need it, and I'll pray windows plays along well.21 -
So I'm writing some multithreaded shit in C that is supposed to work cross-platform. MingW has Posix threads for Windows, so that saved already half of the platform dependency. The other half was that these threads need to run external programs.
Well, there's system(), right? Uhm yes, but it sucks. It's incredibly slow on Windows, and it looks like you can have only one system() call ongoing at the same time. Which kinda defeats the multithreaded driver. Ok, but there's CreateProcessA(), and that doesn't suck.
Fine, now for Linux. The fork/exec hack is quite ugly, but it works and is even fast. Just never use fork() without immediate exec(). First try under Cygwin... crap I fork bombed my system! What is this shit? Ah I fucked up the path names so that the external executable couldn't be run.
Lesson learnt: put an exit() right after the exec() in the path for child process. Should never be reached, but if it goes there, the exit() at least prevents a fork bomb.
Well yeah, sort of works under Cygwin, but only with up to 3 threads. Beyond that, it seems like fork() at some point gives two processes the same PID, and then shit hangs.
Even slapping a mutex around the fork and releasing it only in the parent process didn't help. Fork in Cygwin is like a fork in the ass. posix_spawn() should work better because it can be mapped more easily to the Windows model, but still no dice.
OK, testing under real Linux. Yeah, no issues with that one! But instead, I get some obscure "free(): invalid size" abort. What the fuck would that even mean?! Checking my free() calls: all fine.
Time to fire up GDB in the terminal! Put a catch on the abort signal, mh got just hex data. Shit I forgot to compile with -O0 and -g. Next try. Backtrace shows the full call trace, back to the originating line in my program - which is fclose() on a file.
Ahhh I remember! Under Linux, fclosing a file that is already closed makes the program crash. So probably I was closing it twice. Checking back.. yeah that's where it was.
Shit runs fast on several cores now!8 -
It is time... to rant about macs!
No, seriously - I had such a different experience about which not many talk in real life or pretend that it never happens....
Model: 2015 mid MBP 15" with second to highest specs (don't have dedicated gpu).
Rattling fucking toy.... Yea, it rattles! If you shake/move ir sit in trait/bus - it non-stop rattles as a fucking toy. Worst part? It's confirmed issue by apple and it manifacturing issue that they are not keen on fixing!!!! WTF? We have 4 macs in our office - all of them fucking rattles... God help me how annoying that is. (Lose LCD control panel that unsticks from glue. Replacing it solves the issue for 1 month if you carry it anywhere).
Constant fucking crashing/updates.... Every morning I wake up and don't have an app that requires confirmation for restart - it's restarted. YAY, turning on all apps once again.... Why you may ask? Well, because if you tinker with software in any way - it fails to update it and hell breaks lose. It's been a long time since High-Sierra came around and the issue is still there (not running Mojave as it conflicts with soft I have... Woo!). Tried few times - updates fail. Resolution? Reinstall OS!
OS conflicts with applications - damn... People told me it works out of the box.... Yeah, as long as you don't upgrade the OS - then it breaks. Why? Well, because.
Piece of shit power supply. With 4 of our office power supplies - 2 of them failed twice withing warranty and once afterwards... Really? Not to mention that all 4 are starting to shear the sleeve or already did (mine is just wrapped with white electrical tape to give it a support... lol).
Bluetooth - who the hell needs that in mac, right? Well, people do. To start with - it conflicts with 2.4GHz wireless network - you might have one of those and not both at the same time. Next thing is using a device that needs constant connection (mouse, headphones, keyboard - non apple branded) - shit... They can't stay connected for more than an hour without any issues... Constant battle to re-connect it, to re-pair the device and all due to smart apple bluetooth settings. Hell, my mouse (logitech MX master) was even printing random symbols in some applications if moved. All of the issues went away after using a bluetooth dongle... WOO!!!!
Xcode... Ahh, you may never prepare your mac if you don't download 17GB of fucking xCode libraries that enables some tools to be installed/runned as you can NOT get them in any other way and you have to install full xCode software in order to get them... YAY! 17GB wasted on my 256GB SSD that I can't upgrade. GREAT!
OsX applications - ah, don't get offended but if you are using them and you are fine with them - you are probably a monkey that loves being told what to do. You can't customise any actions, you can't configure it the way you like - either you accept their default workflow or go kill yourself. Yep... Had issues with calendar, mail, iMessages, safari... None of them fit my needs :)
Resolution scaling... Fucking hell, the display is 2880 x 1800 but all you let me to use is 1440x900 without scaling? Am I blind to you? Scaling the resolution means that you are fucked if some applications don't support scaling very well. Looking at you Jetbrains - your IDES suck at scaling and slows down the pc to a potato....
Now the pros - keyboard is way better than the new ones, trackpad is GREAT - no need for mouse (using it on external 4k displays only), the battery life is great - getting around 6h of continues development time, 8 if using sublime instead of phpStorm and well, that's about it...
To clarify:
I've bought this device due to the fact that at that time mac and windows pc's with similiar specs costed the same while windows pc sucked with their quality of the device and trackpad... Now the situation is better and when time comes for a next upgrade - it's going to be one of these:
Razer Blade 15, Dell XPS 15, Lenovo Carbon X1 series.
And of course - LINUX. I've had enough issues with windows, and had enough of retardness of apple ecosystem, so switching it is a must for me.
Disclaimer: I might be an unhappy customer, a bit picky but I'd like my device to be setted up as I like and continue to have that until I don't like, not until the company decides to break it. Not to mention that paying almost a yearly salary in my country for one device - I'd expect it to be at least reliable and work without issues....
Rant over.
ps. You can disagree with me, this is my personal experience with MBP over the last 3 years :)8 -
It's rant time again. I was working on a project which exports data to a zipped csv and uploads it to s3. I asked colleagues to review it, I guess that was a mistake.
Well, two of my lesser known colleague reviewed it and one of the complaints they had is that it wasn't typescript. Well yes good thing you have EYES, i'm not comfortable with typescript yet so I made it in nodejs (which is absolutely fine)
The other guy said that I could stream to the zip file and which I didn't know was possible so I said that's impossible right? (I didn't know some zip algorithms work on streams). And he kept brushing over it and taking about why I should use streams and why. I obviously have used streams before and if had read my code he could see that my code streamed everything to the filesystem and afterwards to s3. He continued to behave like I was a literall child who just used nodejs for 2 seconds. (I'm probably half his age so fair enough). He also assumed that my code would store everything in memory which also isn't true if he had read my code...
Never got an answer out of him and had to google myself and research how zlib works while he was sending me obvious examples how streams work. Which annoyed me because I asked him a very simple question.
Now the worst part, we had a dev meeting and both colleagues started talking about how they want that solutions are checked and talked about beforehand while talking about my project as if it was a failure. But it literally wasn't lol, i use streams for everything except the zipping part myself because I didn't know that was possible.
I was super motivated for this project but fuck this shit, I'm not sure why it annoys me so much. I wanted good feedback not people assuming because I'm young I can't fucking read documentation and also hate that they brought it up specifically pointing to my project, could be a general thing. Fuck me.3 -
I just fucking hate BGAs* that unsolder themselves.
So, thanks to my laptop slowly breaking apart I decided to reactivate an old netbook my father gave me back in 2014(?) when it failed, to have a device on standby if necessary.
Wasn't really planning to repair it and kept it for spare parts mostly as the whole device is a fucking design failure concerning heat dissipation.
But yet again, I thought I'd give it a try one-two years ago. I soon found out it was said heat problem that caused the error in the device and it'd probably only take some reworking using a heat gun, which I did. Netbook worked for some hours, then was dead again, same error. Lost motivation and stashed it until this week.
Reworked with a hair-dryer this time and it worked! Well, until this morning - same error. Perhaps I shouldn't have tried to run a VM and then shut down the device right after that.
I will now try only one more time, this time just baking the whole damn main board thoroughly.
Either it works or it's really dead after. Either way, I'll be somewhat happier then.

Central team: No, your team must be doing something wrong. Our pipeline is super-configurable and works for any situation! You just have to read the docs!
Me: Where are the docs?
Central team: Uhh, well, umm... we'll hook you up with a CI/CD coach!
Me: Okay, cool. In the mean time, can you point me at the repo where all the base scripts are?
Central team: Sure, it's here.
Me, some weeks later: Yeah, uhh, the coach can't seem to figure out how to make our Prod deployment work either.
Central team: That's impossible! It's so easy and completely configurable!
Me: Well, okay... but, here's the thing: your pipeline IS pretty "configurable", in the sense that you look for A LOT of variables...
Central team: See! We told you!
Me: ...none of which are actually documented, so they're just about useless to me...
Central team: But, but the coach...
Me: ...couldn't make heads or taisl of it either despite him literally being ON YOUR TEAM...
Central team: Then your project must just be architected wrong!
Me: Well, we're not perfect, so could be...
Central team: Right!
Me: ...but I think it's far more likely that the scripts... you know, the ACTUAL Python scripts the pipeline executes... while it took me DAYS to get through all your levels of abstraction and indirection and, well, BULLSHIT... it turns out they are incredibly NOT flexible. They do one thing, all the time, basically disregarding any flexibility in the pipeline. So, yeah, I'm thinking this is probably one of this "it's you, not me" deals.
Central team: Waaaaahhhhhhhh!!!!!!2 -
VIM! ViM! vim! Vi Improved! Emacs (Wait ignore that one). What’s this mysterious VIM? Some believe mastering this beast will provide them with untold mastery over the forces of command line editing. Others would just like to know, how you exit the bloody thing. But in essence VIM is essentially a command line text editor at heart and it’s learning curve is so high it’s a circle.
There’s a lot of posts on the inter-webs detailing how to use that cruel mistress that is VIM. But rather then focus on how to be super productive in VIM (because honestly I’ve still not got a clue). This focus on my personal journey, my numerous attempts to use VIM in my day to day work. To eventually being able to call myself a novice.
My VIM journey started in 2010 around the same time I was transiting some of my hobby projects from SVN to GIT. It was around that time, that I attempted to run “git commit” in order to commit some files into one of my repositories.
Notice I didn’t specify the “-m” flag to provide a message. So what happened next. A wild command line editor opened in order for me to specify my message, foolish me assumed this command editor was just like similar editors such as Nano. So much CTRL + C’ing CTRL + Z’ing, CTRL + X’ing and a good measure of Google, I was finally able to exit the thing. Yeah…exit it. At this moment the measure of the complexity of this thing should be kicking in already, but it’s unfair to judge it based on today’s standards of user friendly-ness. It was born in a much simpler time. Before even the mouse graced the realms of the personal computing world.
But anyhow I’ll cut to the chase, for all of you who skipped most of the post to get to this point, it’s “:q!”. That’s the keyboard command to quit…well kinda this will quit the program. But…You know what just go here: The Manual. In-fact that’s probably not going to help either, I recommend reading on :p
My curiosity was peaked. So I went off in search of a way to understand this: VIM thing. It seemed to be pretty awesome, looking at some video’s on YouTube, I could do pretty much what Sublime text could but from the terminal. Imagine ssh’ing into a server and being able to make code edits, with full autocomplete et al. That was the dream, the practice…was something different. So I decided to make the commitment and use VIM for editing one of my existing projects.
So fired the program up and watched the world burn behind me. Ahhh…why can’t I type anything, no matter what I typed nothing seemed to appear on screen. Surely I must be missing something right? Right! After firing up the old Google machine, again it would appear there is this concept known as modes. When VIm starts up it defaults to a mode called “Normal” mode, hitting keys in this mode executes commands. But “Insert” entered by hitting the “i” key allows one to insert text.
Finally I thought I think I understand how this VIM thing works, I can just use “insert” mode to insert text and the arrow keys to move around. Then when I want to execute a command, I just press “Esc” and the command such as the one for saving the file. So there I was happily editing my code using “Insert” mode and the arrow keys, but little did I know that my happiness would be short lived, the arrow keys were soon to be a thorn in my VIM journey.
Join me for part two of this rant in which we learn the untold truth about arrow keys, touch typing and vimrc created from scratch. Until next time..
:q!4 -
probably every time I see my tests failing.
Each time I am writing tests I'm convincing myself "it's an investment", "spend 2 hours now to save 2 days later", "unit-tests are good".
And each time I'm chasing away ideas like "perhaps they are right, perhaps writing unit tests is a waste of time..", "this code is simple, it should ever break - why test it??", "In the 2 hours I'll spend writing those UT I could build another feature"
Yes, it is terribly annoying to write tests, especially after writing the production code (code-first approach). Why test code that you know works, right?
But after a few weeks, months or years, when the time comes to change your feature: enhance it, refactor it, build an integration with/from it, etc, I feel like a child who found a forgotten favourite candy in his pocket when I see my tests failing.
It means I did a very good job writing them
It means it was not a waste of time
it means these tests will now save me hours or days of trial-and-error change→compile→deploy→test cycles.
So yeah, whenever I see my tests fail, I feel warm and fussy inside :)2 -
I already wrote a rant about this yesterday, but since I'm a sysadmin trying to convert to dev.. I dunno, maybe it's not a bad idea to muddy the waters a bit and talk about why not to be a sysadmin.
Personally I think it's that the perceived barrier to entry is just too high, while it isn't. You don't need a huge Ceph cluster and massive servers when you're just starting out. Why overbuild an appliance like that if it's gonna start out at maybe 5 requests a minute?
Let's take an example - DNS servers! So there's been this guy on the bind-users mailing list asking how to set up a DNS server on 2 public servers, along with a website. Nothing special I guess - you can read the thread here: https://0x0.st/ZY-d. Aside from the question being quite confusing, there was advice to read RFC's, get a book, read the BIND ARM, etc etc. And the person to deny this? No one less than Stephane Bortzmeyer, one of the people who works for nic.fr (so he maintains the .fr TLD) and wrote some of those RFC's as part of the DNSOP working group in the IETF. As for valid reasons to set up a DNS server? Could just be to learn how the DNS works, or hell even for fun. As far as professional DNS servers go.. this (https://0x0.st/ZYo9) is the nugget that powers the K root server, one of the 13 root servers that power the root zone of the internet, aka the zone apex. 2 RJ45 connections, and a console connection. The reason why this is possible is the massive recursor networks that ISP's, Google DNS, Cloudflare DNS, Quad9, etc etc provide. Point is, you don't need huge infrastructure to run a server!
Or maybe your business needs email. How many thousands of emails per second are you gonna need to build your mail server against? How many millions will you need to store? If your business has 10 employees and all of those manage about 10k emails total.. well that's easy, 100k emails total. Per second? Hundreds of emails per second per employee? Haha, of course not. Maybe you'll see an email a minute at most. That is not to say that all email services are like this - it is true that ISP's who offer email to their customers, and especially providers like Microsoft and Google do need massive mail servers that can handle thousands of emails per second. But you are not Microsoft or Google. So yeah, focus on the parts of email that are actually hard.. and there is plenty.
Among sysadmins you have this distinction between "professional" sysadmins and homelabbers. I don't mind the distinction itself but I think both augment each other. If you've started out by jumping into a heap of legacy at an established company, you will have plenty of resources, immediately high complexity, and probably a clusterfuck right away. But you will have massive amounts of resources. If you start out with a homelab, you will have not many resources, small workloads, and something completely new for you to build and learn with. And when running a server like that, you'll probably find that the resources required are quite small, to provide you with your new services. My DHCP servers take 12MB memory each. My DNS servers hover around the 40MB mark. The mail server.. to be fair that one consumes around 150. But if you'd hear the people saying that you need huge servers.. omg you need at least a TB of RAM on your server and 72 cores, massive disks and Ceph!1!
No you don't. All that does is scaring people away and creating a toxic environment for everyone. Stop it.1 -
Weeks ago, a change went into production. For some reason, we can't implement our own changes or create new databases in production, we have to have a whole different department do it. This would be great except for one thing:
THEY CAN'T THINK FOR THEMSELVES. I've had to tell them how to run scripts I wrote. I've had to tell them how to fix problems that arise.
Back to that script ran three weeks ago or so. It didn't add permissions to allow me, the system and application developer to see the stored procedure, much less run it. Application can't run it. Thankfully the application works without it.
Fast forward to tonight. My change that I'm attempting to implement is the creation of the stored procedure, because nothing could see it, I assumed it didn't exist... reasonable, right? Database folks tells me it exists. They then tell me they can't give me nor the application permissions because it doesn't ask for it in the change plan.
Excuse me.... WHAT FUCKING WORLD DOES IT MAKE SENSE TO CREATE SOMETHING AND HIDE IT FROM THE CREATOR LET ALONE THE APPLICATION SO IT CAN'T USE IT?! FUCKING THINK. WHY WOULD I WASTE MY FUCKING TIME TO TALK TO YOU OFFSHORE PIECES OF SHIT AT 10PM WHEN I'D RATHER PLAY VIDEO GAMES.
I'm so fucking done with enterprises. Someone with reasonable job security at a startup, please hire me. You will probably pay me more fucking money than this company does anyway.
Now on to my second change of the night. Thankfully I don't have to rely on anyone outside of me... so I won't be wasting my fucking time. -
I'm so fucking fed up with the npm ecosystem. Every single god damn time I've had to do anything it always takes DAYS to figure out how to get anything working and I always have to try multiple tools or libraries to final get it half way sorta.
I'm so fucking annoyed right now. They always turn out not that great, have lacking features or trivial oversights in functionality and ALWAYS have garbage documentation.
I just want to build a fucking npm library with TypeScript to be used with node. That's probably the NUMBER 1 use case so how fucking hard can that be?
So obviously I start out with tsc. That's quite simple, compiles all my stuff and shits out .js and .d.ts files. Okay so how do I use them via es6 import? I don't fucking know, because it doesn't work no matter what I do. The 'module' option in tsconfig is absolutely useless btw. It does *literally* fuck all. Nada. Absolutely nothing.
Okay I'm far from defeated, maybe I'll just have to bundle it. So I waste two days finding something that half works (I'm using fusebox right now) and at last I get a stupid es6 module as a single bundle... But what about type the declarations? They are nowhere to be seen and of course there's no option for that. Because Fusebox the pile of shit that's oh so well Typescript integrated apparently doesn't think TYPE DECLARATION FILES are needed. What the actual fuck.
And that's where I'm now. I need the fucking .d.ts files so I can use it as a module with import. Do I really need another fucking piece of shit tool that bundles these files? Honestly fuck all of this. "Oh the Javascript ecosystem is so great" YEAH fucking great, alright. Where 90% of the ESTABLISHED tools and libraries (we don't talk about the landfill of all the other shit) flat out don't do what you need. Again, how fucking hard can it be to make a npm lib with typescript? That should be NATIVELY SUPPORTED. If not by npm atleast by typescripts tsc.
FUCK NPM. FUCK JAVASCRIPT. AND FUCK THE WHOLE ECOSYSTEM4 -
my company is "pivoting" way too goddamn fast; they are pulling devs from other projects and throwing them into something that is a fragile system (was supposed to be replaced already) and is using a completely different stack than most of them usually work with. they keep promising 3rd parties that we will knock out their requirements within a week or two, and as such they are pushing haphazardly merged feature branches into production with absolutely no regression testing.
then when shit explodes and operations grinds to a halt, they tell the half of the team that actually knows how the system works to drop everything and fix it, and leave the diverted devs to continue to develop shit based on requirements drawn on a cocktail napkin, and then they fucking push both the hotfixes and the newest features at the same time.
I probably have the most tribal knowledge at this company, and they are paying me ok, so it's enough for me to just pour some rye and suck it up for the time being and milk the gig. but this can't be sustainable, right? i'm passively looking around for other work, as I've already had enough being here for over 3 years, but i'm finding most places to be slow on the application/hiring process lately due to covid.
Edit: i think i used the wrong tag here, but what the fuck ever. i haven't figured out how to tag shit properly on any platform3 -
I really hate PHP frameworks.
I also often write my own frameworks but propriety. I have two decades experience doing without frameworks, writing frameworks and using frameworks.
Virtually every PHP framework I've ever used has causes more headaches than if I had simply written the code.
Let me give you an example. I want a tinyint in my database.
> Unknown column type "tinyint" requested.
Oh, doctrine doesn't support it and wont fix. Doctrine is a library that takes a perfectly good feature rich powerful enough database system and nerfs it to the capabilities of mysql 1.0.0 for portability and because the devs don't actually have the time to create a full ORM library. Sadly it's also the defacto for certain filthy disgusting frameworks whose name I shan't speak.
So I add my own type class. Annoying but what can you do.
I have to try to use it and to do so I have to register it in two places like this (pseudo)...
Types::add(Tinyint::class);
Doctrine::add(Tinyint::class);
Seems simply enough so I run it and see...
> Type tinyint already exists.
So I assume it's doing some magic loading it based on the directory and commend out the Type::add line to see.
> Type to be overwritten tinyint does not exist.
Are you fucking kidding me?
At this point I figure out it must be running twice. It's booting twice. Do I get a stack trace by default from a CLI command? Of course not because who would ever need that?
I take a quick look at parent::boot(). HttpKernel is the standard for Cli Commands?
I notice it has state, uses a protected booted property but I'm curious why it tries to boot so many times. I assume it's user error.
After some fiddling around I get a stack trace but only one boot. How is it possible?
It's not user error, the program flow of the framework is just sub par and it just calls boot all over the place.
I use the state variable and I have to do it in a weird way...
> $booted = $this->booted;parent::boot();if (!$booted) {doStuffOnceThatDependsOnParentBootage();}
A bit awkward but not life and death. I could probably just return but believe or not the parent is doing some crap if already booted. A common ugly practice but one that works is to usually call doSomething and have something only work around the state.
The thing is, doctrine does use TINYINT for bool and it gets all super confused now running commands like updates. It keeps trying to push changes when nothing changed. I'm building my own schema differential system for another project and it doesn't have these problems out of the box. It's not clever enough to handle ambiguous reverse mappings when single types are defined and it should be possible to match the right one or heck both are fine in this case. I'd expect ambiguity to be a problem with reverse engineer, not compare schema to an exact schema.
This is numpty country. Changing TINYINT UNSIGNED to TINYINT UNSIGNED. IT can't even compare two before and after strings.
There's a few other boots I could use but who cares. The internet seems to want to use that boot function. There's also init stages missing. Believe it or not there's a shutdown and reboot for the kernel. It might not be obvious but the Type::add line wants to go not in the boot method but in the top level scope along with the class definition. The top level scope is run only once.
I think people using OOP frameworks forget that there's a scope outside of the object in PHP. It's not ideal but does the trick given the functionality is confined to static only. The register command appears to have it's own check and noop or simply overwrite if the command is issued twice making things more confusing as it was working with register type before to merely alias a type to an existing type so that it could detect it from SQL when reverse engineering.
I start to wonder if I should just use columnDefinition.
It's this. Constantly on a daily basis using these pretentious stuck up frameworks and libraries.
It's not just the palava which in this case is relatively mild compared to some of the headaches that arise. It's that if you use a framework you expect basic things out of the box like oh I don't know support for the byte/char/tinyint/int8 type and a differential command that's able to compare two strings to see if they're different.
Some people might say you're using it wrong. There is such a thing as a learning curve and this one goes down, learning all the things it can't do. It's cripplesauce.12 -
So I decided to run mozilla deep speech against some of my local language dataset using transfer learning from existing english model.
I adjusted alphabet and begin the learning.
I have pc with gtx1080 laying around so I utilized that but I recommend to use at least newest rtx 3080 to not waste time ( you can read about how much time it took below ).
Waited for 3 days and error goes to about ~30 so I switched the dataset and error went to about ~1 after a week.
Yeah I waited whole got damn week cause I don’t use this computer daily.
So I picked some audio from youtube to translate speech to text and it works a little. It’s not a masterpiece and I didn’t tested it extensively also didn’t fine tuned it but it works as I expected. It recognizes some words perfectly, other recognize partially, other don’t recognize.
I stopped test at this point as I don’t have any business use or plans for this but probably I’m one of the couple of companies / people right now who have my native language speech to text machine learning model.
I was doing transfer learning for the first time, also first time training from audio and waiting for results for such long time. I can say I’m now convinced that ML is something big.
To sum up, probably with right amount of money and time - about 1-3 months you can make decent speech to text software at home that will work good with your accent and native language. -
I'm having to use MS Word again today, and yet again I want to punch my computer in the balls, and frankly I could pull a better piece of software out of a pig's arse.
So there is a feature that automatically adds up the figures in a column to give you a total. Useful, right?
No. Because the total doesn't update automatically. There is even a setting somewhere to have it update before save, and when you turn this setting on, it sometimes updates before save depending on what mood it's in.
You can have it reliably update before you "print to pdf", but not before you "save as pdf".
Fine, there's probably another setting buried somewhere that actually works, but why the fuck is it not turned on by default? What kind of moron wants an automatic total that doesn't update automatically?
I first encountered this feature about 20 years ago, and in all that time none of the thousands of developers at MS has thought "this is shit, let's fix it."
But that's what a developer does, surely. They look at things and say "this is shit, let's fix it".
If you've been looking at something that's so obviously shit, and so easily fixed, for 20 years and not had any urge to fix it, you're not a developer, you're a cretin.
The stupidity cries out from the earth for vengeance.5 -
!!rant life toptags bottags
My tags seem to be okay. Let's go.
I'm 14. I live in a place where nobody smart lives, and the school I go to has no coders.
Last year, all my friends moved. The only friend I had left now hates me, simply because they yelled at me everyday and I yelled at them once.
I am in the middle of my exams. I also have the flu, but thankfully it's not the e-flu, otherwise you guys should prepare for 24/7 headaches.
Due to the medications I am taking, I'm half-asleep all the time, and I probably am messing up all of my grades.
My entire extended family is in India, and I go there 2 times a year. I miss them so much right now :(.
At the same as doing exams, I am trying to keep my laptop (primary) and PC (secondary, desk) configuration and setup approximately synchronized. In order to do that, I am setting up my dotfiles repository.
Except that all my laptop config (which works) is written horribly, and I need to rewrite it all.
At the same time, I have 3 other projects going on: An OS written in D, a source-based package management system written in D, a small website (not online), and a whatever's cooking in my mind at this moment.
Right now, I'm supposed to be studying for my French exam.
Instead, I'm here, typing this out on my phone.
I have a classmate in school who can type QWERTY at 80WPM. I'm learning Dvorak (Programmer's!) and my current speed is 33WPM, after about 2 months of half-hearted practise during work time and at school.
Sometimes, I look at the world we have here, and what we're doing to it, and I wish that sometimes we could simply be content with life. Let's just live, for once.
I find ~60 random songs in one go, simply by finding a song I know on YouTube and going to the 'Mix - <song>' playlist. I download them all (youtube-dl), and I listen to them. Sometimes, I find this little part in a song (Mackelmore & Ryan Lewis - Can't Hold Us beginning instrumentals, or Safe and Sound chorus instrumentals) that make me feel so happy I feel like all's good in the world. Then the song moves on and with it, my happiness.
I look at Wayland, and X, and I think - Why can't we have one way of doing things - a fixed interface to express anything, so that one common API exists for everything of that type? And I realise it's because they feel that they're missing something from the others. Perhaps it's a bug nobody's solved or functionality that's missing, and they think that they can do better than that. And I think - Well, that's stupid. Submit a fucking bug report or pull request instead of reinventing the wheel. And then I realise that all the programming I've ever done in my life IS simply reinventing the wheel. And some might say, "Well, that guy designed it with spokes and wood. I designed it with rubber and steel," but that doesn't work, because no matter what how you make it, it's just a wheel. They both do the same thing. Both have advantages and disadvantages, because nothing's perfect. We're not perfect because we all have agendas and wants and likes and dislikes and hates and disgusts and all kinds of other crap, and our DNA's not perfect because it manages to corrupt copy operations (which is basically why we die of old age, I think).
And now I've lost my train of thought and this is too large to scroll over so I'm just going to move on to the next topic. At this point (.), I have 1633 letters left.
I hate the fact that the world's become so used to QWERTY because of stuff that happened 100 years ago that Dvorak is enough of a security to stop most people from being able to physically use my laptop.
I don't understand why huge companies like Google want to know about me. What would you do with this information? Know how to take over my stuff when the corporation-opocalypse comes around? Why can't they leave me alone? Why do I have to flash a ROM onto my phone so that Google cannot track me? What do you want, Google?
I don't give a shit any more, so there's my megarant.
Before anybody else (aside from myself) tells me that this is too big, all these topics are related simply because my train of thought went this way. There's a connection between each of these things, but I just don't know what it is.
Goodnight, world. 666 is the number of characters I have left. So is 42, for that matter (thanks, Douglas Adams!). Goodbye.rant life story current project ugh megarant why are you doing this to me life schrodinger's tags 🐈 life3 -
Spent a few hours wrestling with AMD ROCm to get it working. Had to change my kernel a few times, install different versions of the rocm packages, and in one case selectively upgrade a package. I also need to run my programs with a few shady environment variable exports to work around some bugs. The whole thing looks shaky right now, nowhere near as simple as CUDA. Also, horrid names (seriously AMD, what's with the 3dgy names).
However once I got it working it works pretty well, happily training stuff via tensorflow-rocm, with decent performance. This is also probably a good project to contribute to, I'm nowhere close to AMD's engineers at this stuff but basic bug fixing and quality of life stuff are probably within reach.3 -
Let me just say that I've been playing whack a mole with a new feature for while now. And it's becoming very tiring.
TLDR; CTO is changing the way we're going to implement this, every other day.
June 1st,
CEO: let's implement feature AAA,
CTO: we're going to have a call with Andy to tell us all about his product that will make this super easy, call will be June 4th.
Days before June 4th,
Me: Researchs product X, makes demo works flawlessly.
June 4th,
Call all good, few tips from Andy. We come to the pricing section of Product X
CTO: this will not work, pricing doesn't fit on our budget, fair enough.
June 7th -11th
Me: research altenative approach. Makes second demo.
CTO: Works good, seems to have too many moving parts, let's have call with Bob to check Product Y. It should make our lifes easier.
ME: Geee, ok let's check it out.
June 14th,
Call with Bob, all good, product has a fair price, stuff is experimental.
CTO: let's use Product Y, and just use what we get from their api now, and worry about changes later.
Me: Hmmm, that's a bit risky, but ok, you the boss, right?, starts again new demo. API doesn't work as documented.
Lots of trial and error to figure out how the api is working now, finally demo works well,
June 17th,
API changed, now it works as documented, (expected as it is experimental), previous demo doesn't work anymore.
June 18th,
Redoing research. inputs are completely different from Product Y now, need to redo all that is working and do and a lot more of research.
Go live is scheduled for end of next week, I hope that the API is stable now, and that I get to go live on schedule.
It is funny to see, that it would probably been the same if we just waited on the API to stabilize, and check the pricing section before choosing a product? Who knows.
Anyways, I actually feel happy that over the years I developed the patience to work with ever changing situations like this one.4 -

my problem with gaming in linux is not really inherent to linux.
my problem is that there are no linux game torrents.
and torrenting for me is a way to know if I'll be playing a certain game for a while, and eventually buy it.
I can watch all the trailers in the world for a game, but I truly make up my mind after the first few hours of direct playtime.
so I'm not interested in spending money on a game that I might like because it looked nice on the trailer only to find out I hate playing it.
the problem with torrents is that once users get the game, and the game works, they're probably like
"why bother buying it? the game works right? why risk losing the progress i achieved so far by moving save files?"
on top of that on linux, you need to check protondb to see how compatible the game you found is, so an extra layer of difficulty.
I guess I would like to have legal demo versions of games, but I see very little devs doing that so maybe that commercial model failed? I don't know really.16 -
Use Maven, they said... it's better, they said... you don't have to manage dependencies yourself, they said...
...only now I've spent three days in hell trying to figure out why Maven keeps insisting on sticking INCOMPATIBLE JARs in my WAR that causes a breakage when deployed. No matter what I do it still sticks stuff in the WAR that shouldn't be there!
Like, I'm not a lazy cunt, I can manage my own dependencies! I know what's supposed to be there, oh, and by the way, everything fucking works when I build with Ant instead and I'm in full control of what winds up in the WAR.
So, basically, instead of the "hassle" of having to download JARs myself, I've now got the hassle of dealing with Maven trying to be more clever than me.
I know which I'd rather have, especially right now. ARGH!
You know, any time someone says "this is an industry-standard and that's why you should use it" my first thought is "hmm, which of these buildings is tallest and will ensure a quick death when I inevitably jump off of it?" MOST ESPECIALLY when the company just decides X is what everyone is going to switch to, regardless of what they're using now and regardless of how many YEARS it's been that way and working perfectly. Nope, doesn't matter, just get onboard the freight train, and if your productivity takes a hit, if you start missing deadlines dealing with shit you didn't have to deal with when using the "worse" tools, well, I guess that doesn't fucking matter, does it?!
And that's not even talking about the fact that the Maven build takes almost four minutes, which is just about 4x as long as the Ant build it replaced, each and every fucking time I make a change.
Look, I'm sure there are solutions and I'm sure I'll find them next week because I always do... and I'm sure there's some tweaking we can do to improve the performance... and it's not like this is my first go-round with Maven, though it's probably the most complex project I've ever tried to do with it... by my fucking dear god this is a nightmare, and it's not a nightmare of my choosing.
I'm disgusted, tired and defeated, three things I never get when it comes to technology. Congratulations Maven, you're on the verge of breaking someone who doesn't get broken. Another day like the last three and I'm not gonna need Stackoverflow, I'm gonna need a bus schedule so I can figure out exactly when to step off the fucking sidewalk!10 -
I wrote a simple Python script to split a Wikipedia page into manageable chunks. But it took a while to load, so I decided to add a loading indicator. Just a few dots appearing and disappearing. How hard could it be?
"Okay, so I just need a few dots as a loading thing."
"Right, so I suppose I'll need a separate thread for this... Better look up Python's threading again"
"So the thread is working, but it keeps printing it out on separate lines"
"Right, that should fix it ... nope."
"I should probably fix the horrible mess here"
"Hmm... maybe if I replace the weird print() calls with all those extra parameters with sys.stdout.write()..."
"Right, that kind of works, but now there's just a permanent row of dots"
"Okay, that's fixed... Ish."
Well, it works now, but there's a weird mess of two \r's and a somewhat odd loop. Oh, and there's more code for the loading indicator than for the actual functionality. This is CLI by the way.7 -
Goddamned apple. "Just works" my ass.
My girlfriend's 2014 MBP told her an update had already downloaded and she had no choice but to install it, which doesn't bother me. Now, though, it tries to update, then fails, and tells you to run diagnostics. Diagnostics says nothing is wrong, and says to contact support and it boots a minimal version of the OS that only runs a minimal version of safari. You try to access the chat feature and it never fully loads the chat interface. I can probably restore it, but I wanna know what was wrong. It's a really expensive brick right now.3 -
I see a major shift coming up im regards of how we continue to evolve the way our applications work in regards to web based solutions. Http was not meant to do the shit that we are doing today, yeah it works, but it continues to feel like a hack. The advent of A.I and WebAssembly will probably make developers more mindful about compilers and truly optimized code. Languages such as Rust are pointing in the right direction in terms of speed and safety and as our computers become more powerful so will our way to communicate with them. Eventually damn near every web based solution will include A.I even when it is not needed at all.
Regardless of what happens. Yo ass is not going to stop hearing about C++, SQL, and Javascript(top kek)1 -
OMFG bless the guy maintaining MikTex for Windows, if only had installed this instead of TexLive the first time around I'd probably be a lot more sane right now (and I would have passed more uni exams).
I genuinely wanna shout my lungs out in frustration... I wasted over a fucking month trying to get my TexLive install to work the way I wanted it to, and now with just a simple automatic installer everything works exactly the way I wish it did, it's so fucking perfect!

So I made a couple slight modifications to the formula in the previous post and got some pretty cool results.
The original post is here:
https://devrant.com/rants/5632235/...
The default transformation from p, to the new product (call it p2) leads to *very* large products (even for products of the first 100 primes).
Take for example
a = 6229, b = 10477, p = a*b = 65261233
While the new product the formula generates, has a factor tree that contains our factor (a), the product is huge.
How huge?
6489397687944607231601420206388875594346703505936926682969449167115933666916914363806993605...
and
So huge I put the whole number in a pastebin here:
https://pastebin.com/1bC5kqGH
Now, that number DOES contain our example factor 6229. I demonstrated that in the prior post.
But first, it's huge, 2972 digits long, and second, many of its factors are huge too.
Right from the get go I had hunch, and did (p2 mod p) and the result was surprisingly small, much closer to the original product. Then just to see what happens I subtracted this result from the original product.
The modification looks like this:
(p-(((abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1)-p)%p))
The result is '49856916'
Thats within the ballpark of our original product.
And then I factored it.
1, 2, 3, 4, 6, 12, 23, 29, 46, 58, 69, 87, 92, 116, 138, 174, 276, 348, 667, 1334, 2001, 2668, 4002, 6229, 8004, 12458, 18687, 24916, 37374, 74748, 143267, 180641, 286534, 361282, 429801, 541923, 573068, 722564, 859602, 1083846, 1719204, 2167692, 4154743, 8309486, 12464229, 16618972, 24928458, 49856916
Well damn. It's not a-smooth or b-smooth (where 'smoothness' is defined as 'all factors are beneath some number n')
but this is far more approachable than just factoring the original product.
It still requires a value of i equal to
i = floor(a/2)
But the results are actually factorable now if this works for other products.
I rewrote the script and tested on a couple million products and added decimal support, and I'm happy to report it works.
Script is posted here if you want to test it yourself:
https://pastebin.com/RNu1iiQ8
What I'll do next is probably add some basic factorization of trivial primes
(say the first 100), and then figure out the average number of factors in each derived product.
I'm also still working on getting to values of i < a/2, but only having sporadic success.
It also means *very* large numbers (either a subset of them or universally) with *lots* of factors may be reducible to unique products with just two non-trivial factors, but thats a big question mark for now.

Today I was meeting with a researcher in my department so that I could show him how the software I developed works. He graduated from a really good university in electronic engineering, with 100/100 I think, and he can manage to copy&paste some python code. So I didn't expect what happened today.
Guy: 'So I have to give to your program as input this python file which contains a function you need to call, right?'
Me: 'Yep, I mean, that is a jupyter notebook, I need a text file containing only the function which is in that notebook'
Guy: *Downloads the notebook, tries to feed the notebook file into my program*
Me: 'Wait, don't, there probably is a lot of junk related to jupyter notebook, try opening it in notepad++'
Guy: *Opens file, sees a lot of junk text*
Me: 'Yeah, I thought so, you need to save it as plain text or .py'
Guy: *Renames the notebook as .txt*
Me: *Shakes my head without him noticing*
'That won't work, the content of the file won't change like that...' -

There are no right answers in parenting, but there are sure as hell wrong ones and if the fucking backfire effect is too much to keep you from realizing that half of your stupid fucking decisions are delusional at best then you should probably start rethinking some things. I fucking hate dealing with other people fucking up and being stupid and I know I'm going to have to keep dealing with it in one form or another but god why I'm so done with this I just fucking don't want to deal with anyone anymore I don't want to deal with myself anymore
I dunno I don't have anyone to rant to so I can't like be specific here because it's public af but you know typing this makes me feel a little better but I still just don't want to deal with this shit anymore I don't even know what I do want to do there's like nothing the positive feedback is going away and I don't know what to fucking do with myself and I don't know how to change anything I can't fucking fix anything I mean I can fix my shitty code but I'm never getting anywhere with that and whenever I want to fix anything that's actually important I just fuck up regardless of how hard I try I just don't want to fucking try anymore I don't know if I'll actually hit post but I have to put this somewhere so probably but ugh I don't even fucking ugh literally all of my problems are so fucking dumb and small and elementary but I CAN'T FUCKING DO ANYTHING I keep ranting about these fucked up people I have to deal with and yeah they fucking suck and sometimes I wish they didn't exist but I know I'm just as if not more of an idiot and everyone would probably be better off if I didn't exist but wait no that would have happened but you guys don't get to know about that because it's specific and putting that here would fuck shit up but someone else could so that so much better and I don't know everyone who interacts with me is just hurting themselves like fuck why do some friends like blades better than me maybe because I'm even less caring and even more damaging than a stupid fucking inanimate sharp piece of metal god fucking ugh okay I can't focus on anything why is this even okay side rant why are atheists so fucking hated like yes maybe some can't understand their motives for like doing things but nobody can really understand each other's like religious people all use god or gods in their own way why do you have to think of people who have zero gods as opposed to your nonzero as less human than you there's so much wrong with that okay that side rant is over but this whole thing is a side rant so cool fuck my life lol uuh I don't know I don't want to stop typing I don't know why though I guess I just actually I have no fucking idea I'm just here doing this I should be like fucking asleep I'm passing the fuck out after this ugh okay okay okay okay okay okay okay umm I really want to quote a certain person that I really hate right now and dissect them and prove every single fucking stupid argument they make wrong but I feel like that would not be good since this is so public but I swear I hate this and you know what if you're thinking that yes I AM A FUCKING WHINY BITCH DEAL WITH IT I'M WHINING YOU DENSE FUCKER YOU DON'T HAVE TO POINT IT OUT AND FEEL SMUG IT'S BETTER TO VENT HERE THAN A LOT OF OTHER WAYS SO JUST SHUT THE FUCK UP OKAY ACTUALLY FUCK IT CALL ME OUT ON IT I NEED SOMETHING TO TAKE THIS OUT ON GOD AAAAAAH okay uuh yeah that's fun I'm a fuck up okay okay so you ask "how can you be a fuck up you're so young her der" okay being young generally is a disadvantage because you haven't had opportunity but boy have I and I sure fucked every single one of those up so yeah fun stuff you know woo haha mmkay I wish I had friends online this late because then I could like rant to a person and shit I mean this community is people but not people I know and it's not really back and forth as much and ugh okay right uuh yeah good um ugh I used to be able to get this shit out by doing something I'm good at but now I'm shit at everything and I can't motivate myself and it's all just bottled up and there's so much shit and nothing works and fuck there's probably a simple solution to everything I'm facing but I'm such a dense piece of shit that I can't find any of those stupid fucking ugh okay now I'm looking at my stupid hands typing ugh I hate the things right back up here uuh uuh I have 500 charas left lets fucking go I don't want to stop I mean I do want to stop but like by that I mean I just want to not exist I do want to keep typing here because it's the only thing distracting me but yeah uuh right um some people were like wtf happened with your stalking thing and this isn't where I should put it but fuck it whatever some weird guy just logged on for 10 mins to take a screenshot of the time being 2:22:22 and logged off and boom the school year ended uuh yeah kay right fuck I have to end it now
Aaaah okay uuh right bye I'm really sorry if you actually read that whole thing4 -
From the last 3 years, i have accumulated interest and experience in android dev. Not sure about the future, but that's probably where i will be.
But this fact is moot to our 50 year old grumpy professors teaching 1000 year old rusted computer syllabus, who rejected my idea of a video streaming app as major project, simply because i projected it as a social media app, and "everyone is making a social media app, its such an old topic". yeah right sir, its younger than your daughter that fucks in the lobby
Now we are doing a project on file conversions website, a project suggested by my team member and my good friend. its such a shitty topic, there is no resources available, even the research papers are bad , every search points to a shitty site, and i don't know shit about web dev.
Technically i am the team leader, but my team mate won't let me make the project as android native app, because "Brooo, i am going to make a react app that would be completely offline, completely client side, full secure and shitt small" and sometimes "Bro its my idea" .
Well, 1. the whole point of client side is stupid because the 18 mb jsfile isn't going to get downloaded first in the client's cache(or whatever the process is, idk). The top stack overflow answers i saw told me to buy an ec2 instance and run liberoffice commands on it for every request, and that's SERVER SIDE. even if we could, i am sure its going to be bigger than what i would have made in kotlin.
2. what am i supposed to do? look at you coding while make all the ppts and research paper? you are going to use undocumented libs that "just works" , and i am suppose to curate the theory behind this, looking at all the researches of the world?well i guess okay that's a light job since THERE AREN'T ANY.
And we are targetting all types of conversions, nice. from what i know, handbrake.fr: video conversion s/w = 16 mb. photoshop: image conversion s/w=1gb and ms word: doc to pdf/other formats= 500mb.
Plus all those proprietary and undocumented formats, ugh. Thank you ugly ass companies.
Internet is great but web dev has become a whole lot mess. "I am going to build a software that is going to run in your system only using your device's processor" is a desktop/mobile app, not a website -
Am I in developer hell already? A shitty project is about to come to an end (hopefully), or should I rather say: It needs to come to an end. But I am still quite lost in how to deal with it, hence procrastinating on it - making the deadline come closer and with it the realization that I'll probably have to rewrite almost everything. I'm not sure how, but I do know that the current code is a dumpster fire.
Basically what I need to do is dealing with the APIs of different payment providers/gateways (like PayPal, AmazonPay). For most cases I'll get a payment ID from the shop and need to act on it later, e.g. capture the authorized money in the case of a credit card transaction or do refunds (without user interaction, unless there is an error). Now at first I put something together where I try to abstract the payment information into two tables:
orders{1}<->{0..n}payments
payments{1}<->{1..n}paymentDetails
Unfortunately trying to abstract the different payment methods and to squeeze them (and their different possible stati and functions) in these tables was not very successful, it's a total mess with magic numbers, half-broken behavior and without any consideration for partial payments/captures or unfinished requests (i.e. if there is an exception before the response is dealt with, there is no indication that anything has ever been sent). Also the current amount is calculated through the history of the paymentDetails table, which basically works differently for each payment type.
How to fix this mess in a way that I'll still have a job by next week?
I'm trying to improve the db schema first, as I think my biggest problems are lying there. Through some research I've come across a recommendation for making payment type specific subtables (with a magic number/string in the main table to prevent having to look up all subtables). That way I can record what I send and receive without having to abstract it too much, so I'll have an acceptable transaction log. The paymentDetails table can be removed (necessary fields go to the payments table). The payments table gets multiple fields for the amount (differentiating between open, authorized, captured, processing and refunded values) and always reflects the current status.
Tables:
payments
paymentRequestsPaypal
paymentRequestsAmazonpay
paymentRequestsXyz
I think I'm going in the right direction here. hm. Maybe there's some light at the end of this long, dark tunnel. Or a train. I'll have two days to find out.question kill me already send help thank you for being my rubber duck payment gateways deadline approaching rant/question burnout6 -
Fucking hate to explain basic shit to computer illiterate. Usually I don't mind, but right know I working on the project, want to automate one thing I need to do every morning, put two numbers to web page(I will explain details maybe in next rant). So I am only one who fix, buys computers, printer(for some problems I call for other repair man.). Generally speaking working as IT guy. Firm has like 50 computers, some of them has SCADA software. Some computers have Win 7, some win 8 and others win 10, can't upgrade those computers, not enough money(I can deal with this problem). And yes, computer buying is not the fastest, easiest thing too. Because is public firm, I need to do public buying(I don't know how to translate to english), and most of the time wins the lowest price, I am ok with that. But I can't on item specification write I want that model pc or it components. Example: I can't write I want intel processor, however I can write number of cores, frequency. But it's not that bad, usually i have template for all things I buy. One of the worst thing is this, our firm bought new bookkeeping software version, old version was using visual foxpro framework. Good thing I didn't initiate the purchase, because right know I would be jobless, not because I would be fired, but because our senior accountant would drive me crazy. In fact accountants drive me crazy, but I can handle it for now. As I wrote before our form has about 120 workers, major part of workers are old, like my parents age. (I am 28 btw. Mom is 55.). As you all know what happens if you say you work with computers. So our accountants are like 60 years old, got new program, don't know how to work with it, and they ask me how to do certain things. if I don't know how to I ask program's support, every question is like 90 Eur. So in short accountants expect I should know their work and how program works. If I try say something they don't like, they try to make my day hard. Next thing is our billing program. Man that worked before me done some payments import. And when I came everyone expect me to do that. Ok I did that because that people working with billing program would probably fuck it up. And I semi automated that, so I don't mind that much. Sometimes that program fucks up, like it happened yesterday, it send email invoices attachment without filename. Example: people got this attachment ".pdf"(no filename, only extension), And if you save it you need do OPEN WITH command and then select pdf reader or rename file (I don't know what easier). And surprise surprise our firm, customer support redirects all phone calls, emails to me. But I did explain to customer support what to say to people. Still they redirect it to me.
PS: This is my first job after school. I work as part time.
TL;DR Thinking my life, carrier choices. accountants are not the nicest people.8 -
Algolia says:
"So our price widget doesn't allow decimals, you'll have to create a custom widget"
I do it.
"Hey, It's not working and I verified it's applying the filter correctly. I noticed my price is a string in your index, maybe that's incorrect and causing it to not work?"
They say: "Yep, you'll need to run an update to fix that and change all to floats" (charges an arm and a leg for the thousands of index operations needed to update the data type)
I clear the index and send a single one as a test, verifying it's a float by casting it using (float) then var_dumping. It shows "double(3.99)", but when it gets to Algolia, it's 0.
So I contact support.
"Hi, I'm sending across floats like you say but it's receiving it as 0, am I doing something wrong? Here's my code and the result of the var_dump"
They respond: "Looks like you're doing it right, but our log shows us receiving 3.999399593939, maybe check your PHP.ini for "serialize_precision" and make sure it's set to -1"
I check and it's fine, then I realize that var_dump is probably rounding to 2 decimal points so I change my cast to (float) number_format($row['Price'], 2) and wallah...it works.
Now I've wasted days of paying for their service, a ton of charges for indexing operations, and it was such a simple fix.
if they had thrown an error for the infinite decimal, that would have helped, but instead I had to reach out to find out that was the issue.

Anytime I write a line of code that works correctly the first time, I’m ecstatic. If I write a whole block or function that works right the first time, I freak out with happiness. Yes, I’m that bad at coding. The rest of y’all probably do such things on the regular and it no biggie. But for me, it’s vanishingly rare.

So as a personal project for work I decided to start data logging facility variables, it's something that we might need to pickup at some point in the future so decided to take the initiative since I'm the new guy.
I setup some basic current loop sensors are things like gas line pressures for bulk nitrogen and compressed air but decided to go with a more advanced system for logging the temperature and humidity in the labs. These sensors come with 'software' it's a web site you host internally. Cool so I just need to build a simple web server to run these PoE sensors. No big deal right, it's just an IIS service. Months after ordering Server 2019 though SSC I get 4 activation codes 2 MAK and 2 KMS. I won the lottery now i just have to download the server 2019 retail ISO and... Won't take the keys. Back to purchasing, "oh I can download that for you, what key is yours". Um... I dunno you sent me 4 Can I just get the link, "well you have to have a login". Ok what building are you in I'll drive over with a USB key (hoping there on the same campus), "the download keeps stopping, I'll contact the IT service in your building". a week later I get an install ISO and still no one knows that key is mine. Local IT service suggests it's probably a MAK key since I originally got a quote for a retail copy and we don't run a KMS server on the network I'm using for testing. We'll doesn't windows reject all 4 keys then proceed to register with a non-existent KMS server on the network I'm using for testing. Great so now this server that is supposed to connected to a private network for the sensors and use the second NIC for an internet connection has to be connected to the old network that I'm using for testing because that's where the KMS server seems to be. Ok no big deal the old network has internet except the powers that be want to migrate everything to the new more secure network but I still need to be connected to the KMS server because they sent me the wrong key. So I'm up to three network cards and some of my basic sensors are running on yet another network and I want to migrate the management software to this hardware to have all my data logging in one system. I had to label the Ethernet ports so I could hand over the hardware for certification and security scans.
So at this point I have my system running with a couple sensors setup with static IP's because I haven't had time to setup the DNS for the private network the sensors run on. Local IT goes to install McAfee and can't because it isn't compatible with anything after 1809 or later, I get a message back that " we only support up to 1709" I point out that it's server 2019, "Oh yeah, let me ask about that" a bunch of back and forth ensues and finally Local IT get's a version of McAfee that will install, runs security scan again i get a message back. " There are two high risk issues on your server", my blood pressure is getting high as well. The risks there looking at McAfee versions are out of date and windows Defender is disabled (because of McAfee).
There's a low risk issue as well, something relating to the DNS service I didn't fully setup. I tell local IT just disable it for now, then think we'll heck I'll remote in and do it. Nope can't remote into my server, oh they renamed it well that's lot going to stay that way but whatever oh here's the IP they assigned it, nope cant remote in no privileges. Ok so I run up three flights of stairs to local IT before they leave for the day log into my server yup RDP is enabled, odd but whatever let's delete the DNS role for now, nope you don't have admin privileges. Now I'm really getting displeased, I can;t have admin privileges on the network you want me to use to support the service on a system you can't support and I'm supposed to believe you can migrate the life safety systems you want us to move. I'm using my system to prove that the 2FA system works, at this rate I'm going to have 2FA access to a completely worthless broken system in a few years. good thing I rebuilt the whole server in a VM I'm planning to deploy before I get the official one back. I'm skipping a lot of the ridiculous back and forth conversations because the more I think about it the more irritated I get.1
