I'm really not much of a drinker, but last night I was apparently.
I thought I played video games until I passed out on the couch and was carried to bed.
This morning, my laptop reveals to me that I had an idea for a web app last night because I made a very misspelled, yet highly detailed to do list for the app, a very blank index file, and 37 open tabs of what looks like research for certain web features.
Project seemed to be some sort of organization thing with a lot of really random and unrelated features like "fruit meterr that scales different fruits you earn" (what does that even mean??) and "sassy bill reminder".
I'm closing out all the tabs I had opened, when I see the tab showing the domain name I chose and bought. I even got the SSL certificate and email domain purchased.
Drunk me seemed to have been really excited about this idea 😶19 -
Me: Optimize a sort & match method in backend because users complain it's a bit slow.
Coworker: These algorithms are both O(n), so they're identical *closes PR*
Me: *start zoom call* "Heeeeeeeeeey Iiiiiiiiiii wouuuuuuuld liiiiiiiiike toooooo diiiiiisscuuuuus thaaaaaaaat puuuuuuulllll reeeeeequuuueeest yooooouuuuu cloooooossseeeed"
Coworker: "wtf are you doing, why are you talking so slow"
Me: "No matter whether I talk fast or slow, the information still reaches you in O(n) time, so why are you complaining"
I fucking hate it when people misunderstand the purpose of (or abuse) big O notation. It's an estimate of how an algorithm SCALES once the set increases in size, in which case you leave out both less significant terms and constant factors.
But those terms and factors are important when you're talking about the DIRECT PERFORMANCE of the algorithm on fixed-size sets, instead of SCALING to larger sets.
1n and 10n are both O(n), but 10x performance on a job that used to take 10 minutes is still significant.19 -

I am a PHP developer.
Yeah, "another PHP is awful" rant... no, not really.
It's just unsuitable for some ambitious projects, just like Ruby and Python are.
First of all, DO NOT EVER use Laravel for large enterprise applications. The same goes for RoR, Django, and other ActiveRecord MVCs.
They are all neat frameworks for writing a todo app, as a better-than-wordpress flexible blogging solution, even as a custom webshop.
Beyond 50k daily users, Active Record becomes hell due to it's lazy fat querying habits. At more than a million users... *depressed sigh*.
PHP is also completely unsuitable for projects beyond 5M lines of code in my opinion. At more than 25M lines... *another depressed sigh*.
You can let your devs read Clean Code and books about architecture patterns, you can teach them about SOLID & DRY, you can write thousands of tests... it doesn't matter.
PHP is scaffolding, it's made of bamboo and rope. It's not brick or concrete. You can build quickly, but it only scales up to a certain point before it breaks in multiple places.
Eventually you run into patterns where even 100% test coverage still doesn't guarantee shit, because the real-life edge cases are just too complex and numerous.
When you're working on a multi-party invoicing system with adapters for various tax codes, or an availability/planning system working across timezones, or systems which implement geographical routefinding coupled to traffic, event & weather prediction...
PHP, Python, Ruby, etc are just missing types.
Every day I run into bugs which could have been prevented if you could use ADTs in a generic way in PHP. PHP7 has pretty good typehints, and they prevent a lot of messy behavior, but they aren't composable. There is no way to tell PHP "this method accepts a Collection of Users", or "this methods returns maybe either an Apple or a Pear, and I want to force the caller to handle both Apple/Pear and null".
Well, you could do that, but it requires a lot of custom classes and trickery, and you have to rewrite the same logic if you want to typehint a "Collection of Departments" instead of "Collection of Users" -- i.e., it's not composable.
Probably the biggest issue is that languages with a (mostly) structural type system (Haskell, Rust, even C#/JVM languages to some degree, etc) are much slower to develop in for the "startup" era of a project, so you grab a weak, quick prototyping language to get started.
Then, when you reach a more grown up phase, you wish you had a better type system at your disposal...28 -

The stupid stories of how I was able to break my schools network just to get better internet, as well as more ridiculous fun. XD
1st year:
It was my freshman year in college. The internet sucked really, really, really badly! Too many people were clearly using it. I had to find another way to remedy this. Upon some further research through Google I found out that one can in fact turn their computer into a router. Now what’s interesting about this network is that it only works with computers by downloading the necessary software that this network provides for you. Some weird software that actually looks through your computer and makes sure it’s ok to be added to the network. Unfortunately, routers can’t download and install that software, thus no internet… but a PC that can be changed into a router itself is a different story. I found that I can download the software check the PC and then turn on my Router feature. Viola, personal fast internet connected directly into the wall. No more sharing a single shitty router!
2nd year:
This was about the year when bitcoin mining was becoming a thing, and everyone was in on it. My shitty computer couldn’t possibly pull off mining for bitcoins. I needed something faster. How I found out that I could use my schools servers was merely an accident.
I had been installing the software on every possible PC I owned, but alas all my PC’s were just not fast enough. I decided to try it on the RDS server. It worked; the command window was pumping out coins! What I came to find out was that the RDS server had 36 cores. This thing was a beast! And it made sense that it could actually pull off mining for bitcoins. A couple nights later I signed in remotely to the RDS server. I created a macro that would continuously move my mouse around in the Remote desktop screen to keep my session alive at all times, and then I’d start my bitcoin mining operation. The following morning I wake up and my session was gone. How sad I thought. I quickly try to remote back in to see what I had collected. “Error, could not connect”. Weird… this usually never happens, maybe I did the remoting wrong. I went to my schools website to do some research on my remoting problem. It was down. In fact, everything was down… I come to find out that I had accidentally shut down the schools network because of my mining operation. I wasn’t found out, but I haven’t done any mining since then.
3rd year:
As an engineering student I found out that all engineering students get access to the school’s VPN. Cool, it is technically used to get around some wonky issues with remoting into the RDS servers. What I come to find out, after messing around with it frequently, is that I can actually use the VPN against the screwed up security on the network. Remember, how I told you that a program has to be downloaded and then one can be accepted into the network? Well, I was able to bypass all of that, simply by using the school’s VPN against itself… How dense does one have to be to not have patched that one?
4th year:
It was another programming day, and I needed access to my phones memory. Using some specially made apps I could easily connect to my phone from my computer and continue my work. But what I found out was that I could in fact travel around in the network. I discovered that I can, in fact, access my phone through the network from anywhere. What resulted was the discovery that the network scales the entirety of the school. I discovered that if I left my phone down in the engineering building and then went north to the biology building, I could still continue to access it. This seems like a very fatal flaw. My idea is to hook up a webcam to a robot and remotely controlling it from the RDS servers and having this little robot go to my classes for me.
What crazy shit have you done at your University?9 -
I just hit the scales this morning. I need to lose 10 kg ASAP.
My brain loves programming but my body hates it.19 -
The new figma plugins are actually insane lol, some examples:
- font scale, always struggled with having to apply the formula myself or finding the right one so it scales nicely
- image tracer, that plugin replaces adobe illustrator for me, since I only used it to convert pixels to vector images
- removebg, 99% of what I pulled photoshop up for
still have to test them some more, but so far it literally replaces all that adobe crap for me.

Im going to boast for a second. I wrote a lockless multi producer c++ thread pool that scales linearly, doesn't eat cpu on no work, and has a proper packaged_task + futures interface. It's fucking awesome, and that is all. Thanks for reading 😎3 -
Me: develops my first android app with firebase by google.
Me: finishes app, tests it and it works.
Firebase after 3 months: we were first going to scale our servers on our own based on how many people are simultaneously using your app. But now fuck you, we will have a cap of 100000 simultaneous users.
Me: fuck this kills my app if it scales. Have to Shard everything on the db side and overhaul the entire app to work will multiple db instances. Takes a month.
Android after 6 months: dude your app is working fine without any hiccups. Let me fuck it up. We will stop all your services when your app is not running or backgrounded. Also we will make it illegal to start services in this case and we will throw exceptions.
Me: what the actual fuck. They now want me to focus on a JobScheduler, fine... But now even intent services won't work properly. So use a job scheduler to start a JobIntentService which is essentially another job scheduler for queuing. wtf android.
Ps solved it and works again.
PS: WAITING FOR ANDROID TO FML WITH ANOTHER NEW VERSION. Maybe they'll say you can't run your app at all now4 -
So I've started learning Rust and I must say it feels great! But some parts of the language, like enums, are quite different than what I'm used to.
As a proof of concept I've reimplemented a small API (an Azure Function App) in Rust with Actix Web and it's FAST AS FUCK BOIII.
The response is served about 5x as quckly and the memory footprint shrinked from some 90 MB to around 5 MB.
In my small scale usecase it's not a huge difference, but I think it can be massive at large scales...
What is your experience with Rust (at scale)?
I wish I could quickly reimplement the whole fucking CMS Of Doom™ in Rust... but no time and resources :(5 -
I don't seem to understand why so many developers nowadays are focused on learning newer frameworks rather than focusing on best practices and learning how to code better.
"Hey I learnt React today, we should totally switch to it because it's so amazing"
> mfw the same guy doesn't even know how to follow coding styles, write good code that scales or document his code.
I think some people need to take a step back and focus on the more vital tasks of writing good code to begin with rather than getting so excited about every new thing that surfaces. It's annoying as fuck to deal with some of these people who you have to work alongside and be able to read their loopy shit code and all they are doing in their time is refreshing hackernews.8 -
There are a couple of them to list! But to sum my main ones(biggest personal heroes):
John McCarthy, one of the founding fathers of Artificial Intelligence and accredited with coining such term(sometimes before 1960 if memory serves right), a mathematical prodigy, the man based the original model of the Lisp programming language in lambda calculus. Many modern concepts that we have in programming where implemented in one way or another from his systems back in the day, and as a data analyst and ML nut.....well I am a big fan.
Herb Sutter: C++ programmer extraordinaire. I appreciate him more for his lectures and published articles than anything else. Incredibly smart and down to earth and manages to make C++ less intimidating while still approaching it with respect.
Rich Hickey: The mastermind behind Clojure, the Lisp dialect for the JVM. Rich is really talented and his lectures behind his motivations and reasons behind everything he does with Clojure are fascinating to see.
Ryan Dahl: Awww shit y'all know how it is. The man changed web development both in the backend and the frontend for good. The concept of people writing their own servers to run their pages was not new, but the Node JS runtime environment made it more widely available to people by means of a simple to use language that was already popular with web developers. I would venture to say that Ryan's amazing contributions to JS made the language better, as it stands, the language continues to evolve and new features that make it overall better keep being added. He is currently building Deno, which would be a runtime environment for TypeScript, in Rust.
Anders Hejlsberg: This dude was everywhere man....the original author of Turbo Pascal and the lead of Delphi back in the day. These RAD tools paved the way for what would be a revolution in the computing world. The dude is also the lead architect and designer of the C# programming language as well as TypeScript.
This fucker is everywhere and I love it.
Yukihiro "Matz" Matsumoto: Matsumoto san is the creator of the Ruby programming language. Not only am I a die hard fan of Ruby, but of the core philosophies that the man keeps as the core of his language design: Make the developer happy, principle of least surprise. Also I follow: minswan which is a term made by the Ruby community that states Mats is nice so we are nice. <---- because being cool to others is better than being a passive aggressive cunt.
Steve Wozniak: I feel as if the man does not get enough recognition...the man designed the Apple || computer which (regardless of how much most of y'all bitch and whine) paved the way for modern micro computers. Dude is also accredited with designing one of the first programmable universal remotes(which momma said was shitty) but he did none the less.
Alan Kay: Developed Smalltalk and the original OOP way of doing things. Smalltalk as a concept is really fucking interesting. If you guys ever get the chance, play with Pharo, which is a modern Smalltalk. The thing is really interesting and the overall idea of Smalltalk can be grasped in very little time. It sucks because the software scales beautifully in terms of project building, the idea of hoisting a program as its own runtime environment and ide by preserving state through images is just mind blowing to me. Makes file based programs feel....well....quaint.
Those are some of the biggest dudes for me. I know that the list is large, but I wanted to give credit to the people that inspired me the most. Honorary mention goes to other language creators and engineers of course, but it would be way too large to list!9 -
I just finished something!
Okay, it's just a quickly thrown together python script that takes a directory of portraits, centers and scales the face closest to the center of the image and creates a gif. Made it for a friend who is doing this one portrait each day thing.
Nothing big at all, but damn does it feel good anyways 😁 -
I'm writing a devrant like site, so a kind of forum that supports live chat under every article. Login will be just username and password to stay anonymous. Email is optional for password reset. Also it won't have password requirements. Who cares if user uses insecure password. I do like the devrant avatar thing. I will use the ducky generator instead. So everyone on the site is a custom duck. K-SASS prolly never expected his generator to be used anywhere. The requirement of this site is that it scales very well. I have db calls of 0.006s, this is for persistent data only and will be used by all site instances. I expect that it can handle many clients concurrent as long I do not return more than 30 rows or so. Events get handled by a self written pubsub server.
All sounds great and development goes fine. But why is this a rant? Because the same thing as always is biting me, I can't design a site at all. I know how but I don't have any feeling for design at all making me almost incapable of building an attractive site. The only thing I can 'design' is an application in bootstrap or smth. I spend so much time one design while I don't like to do it ironically. But looks of site is almost as important as an good working site. Good working site doesn't get used if looks bad in many casee. This is since the start of my career an issue and it sucks that I appearantly can't deliver a whole site on my own meeting my standards.
My backend work is top notch tho. Btw, this application is not to be an alternative for devrant. I do not think I can attract more users than it already has and I've seen two communities disappearing once because someone decided to make a new one, took half of community with him and both communities died after short while.
End product of this project is a working project, not a live site hosted somewhere. It's pure about mixing mostly self written tech to get the best performance. Reinventing wheel on many levels. I wanted maybe to do the site in C but decided that it's way to much work for the value. I change the site so rapid since I don't have decent plan that python aiohttp is the best choice in amount of writing it yourself and fast. It's very lightweight.
More a story than a rant, sorry27 -
I was tasked to evaluate wherever a customer could use an implementation of OTRS ( https://otrs.com/ )
Is it just me or is there no information on this site apart from <OTRS> will make your life better! <OTRS> will cure AIDS! <OTRS> will end world hunger!
This site is trying to use its fucking product name in every god damn sentence. <OTRS>. Everytime <OTRS> is mentioned it is fucking bold printed! My eyes are bleeding within 2 minutes of visiting this site.
I can't get any information about what excatly it is apart from their catchphrase: OTRS (again, bold. I'll refrain from putting it in <> from now, i think you got the point) is a customizable support desk software that manages workflows and structures communication so there are no limits to what your service team can achieve.
So, it's a support desk software you can customize. Great. What does it do?
"Whether you deal with thousands of inquiries and incidents daily [...] you’ll need digital structures that integrate standardized processes
and make communication transparent between teams and departments,
as well as for external customers."
Great, but what does it do?
"Reduce costs and improve satisfaction by structuring customer service communication with OTRS."
Great, BUT WHAT DOES IT DO?
"Manage incidents simply and uncover the data needed to make forward-thinking strategy decisions. OTRS is an ITSM solution that scales and adapts to your changing business needs."
W H A T D O E S I T D O ?!
Okay fuck that, maybe the product page has something to say.
Hm... A link on the bottom of the page says it is a feature list ( https://otrs.com/product-otrs/... )
Ah great, so i got a rough idea about what it is. Our customer wants a blackboard solution with a window you can pin to your desktop and also has a basic level of access control.
So it seems to be way to overloaded on features to recommend it to them. Well, let's see if can at least do everything they want. So i need screenshots of the application. Does the site show any of them? I dare you to find out.
Spoiler: It does not. FFS. The only pictures they show you are fucking mock ups and the rest is stock photos.
Alright, onwards to Google Images then.
Ah, so it's a ticket system then. Great, the site did not really communicate that at all.
Awesome, that's not what i wanted at all. That's not even what the customer wanted at all! Who fucking thought that OTRS was a good idea for them!
Fuck!5 -
Python: I heard you like importing stuff explicitly, so I made sure you had to import every mother-fucking thing you need. Even the things that you obviously need and couldn't possibly do anything without.
What's that? You want more import statements than actual code? Look no further than Python, my friend. At least it scales, amirite? -
Not a rant, but maybe someone can help me on this one.
I am currently working on an app that will hopefully go live by the end of the year. Up to now, the webserver and database (for the REST API) is running on an old linux machine. However, as my ISP is not really reliable I want to move this stuff somewhere else. Has someone experience with the varios hosting providers? Currently I am a little bit overwhelmed by all the different solutions out there.
Ideally I would want something that doesn't cost very much now, but also scales with more users.
To make it more concrete, it's basically about neo4j + REST API in Python
Can somehow recommend anything? I really appreciate it, as I am currently a little bit lost on this.
Thanks for reading this!27 -
My laptop is 14 inch 1080p resolution display. None of the desktop environments scales correctly. Most of the time the font will ne too small or webpages on chrome looks weird.I want the display to look when on windows 10. I really want to switch to linux(gnome) but this is hogging me.13

v0.0005a (alpha)
- class support added to lua thanks to yonaba.
- rkUIs class created
- new panel class
- added drawing code for panel
- fixed bug where some sides of the UI's border were failing to drawing (line rendering quark)
v0.0014a (alpha) 11.30.2023 (~2 hours)
- successfully retrieving basic data from save folder, load text into lua from files
- added 'props' property to Entity class
- added a props table to control what gets serialized and what doesn't
- added a save() base method for instances (has to be overridden to be useful beyond the basics)
- moved the lume.serialize() call into the :save() method on the base entity class itself
- serialized and successfully saved an entities property table.
- fixed deserializion bugs involving wrong indexes (savedata[1] not savedata[2])
- moved deserialization from temp code, into line loading loop itself (assuming each item is on one line)
- deser'd test data, and init()'d new player Entity using the freshly-loaded data, and displayed the entity sprite
All in all not a bad session. Understanding filing handling and how to interact with the directory system was the biggest hurdle I was worried about for building my tools.
Next steps will be defining some basic UI elements (with overridable draw code), and then loading and initializing the UI from lua or json.
New projects can be set as subfolders folders in appdata, using 'Setidentity("appname/projectname") to keep things clean.
I'm not even dreading writing basic syntax highlighting!
Idea is to dogfood the whole process. UI is in-engine rendered just like you might see with godot, unity, or gamemaker, that way I have maximum flexibility to style it the way I want. I'm familiar enough with constructing from polygons, on top of stenciling, on top of nine-slicing, on top of existing tweening and special effects, that I can achieve exactly what I want.
Idea is to build a really well managed asset pipeline. Stencyl, as 'crappy' as it appeared, and 'for education' was a master class in how to do things the correct way, it was just horribly bloated while doing it.
Logical tilesets that you import, can rearrange through drag-n-drop, assign custom tile shapes to, physics materials, collisions groups, name, add tag data to, all in one editor? Yes please.
Every other 2D editor is basic-bitch, has you importing images, and at most generates different scales and does the slicing for you.
Code editor? Everything behavior was in a component, with custom fields. All your code goes into a list of events, which you can toggle on and off with a proper toggle button, so you can explicitly experiment, instead of commenting shit out (yes git is better, but we're talking solo amateurs here, they're not gonna be using git out the gate unless they already know what they're doing).
Components all have an image assignable to identify them, along with a description field, and they're arranged in a 2d grid for easy browsing, copying, modifying.
The physics shape editor, the animation editor, the map editor, all of it was so bare bones and yet had things others didn't.
I want that, except without the historic ties to flash, without the overhead of java, and with sexier fucking in-engine rendering of the UI and support for modding and in-engine custom tools.
Not really doing it for anyone except myself, and doubt I'll get very far, but since I dropped looking for easy solutions, I've just been powering through all the areas I don't understand and doing the work.
I rediscovered my love of programming after 3-4 years of learning to hate it, and things are looking up.2 -
Psychotherapy revealed that EVERY. SINGLE. PAIN I have goes back to my mother in one way or another. Not just her, but her betraying me as a kid.
He once sent me to a summer camp. There, I was bullied and routinely beaten. I once was beaten by a group of girls. I begged my mother to take me back home, but she refused. She told me beatings were no big deal.
This is what ultimately tipped the scales and lead to a chain reaction that ultimately made me disown her.
Here’s the incomplete list of things she did to me: https://devrant.com/rants/9940652/...2 -
Not so much a rant.
I just love the feeling when you test a site on mobile and you can't help but say to yourself, "Damn, I'm good" because the menu is just so usable and scales beautifully.1 -
Not sure if any of you guys are Windows Insiders (I know the audience here is Linux fanboys and plus, there's not much reason to be an insider in 2021, really), but I am. I'm on build 21286 and for whatever reason... they have decided to SLOW down the animation for opening a new window. I'm too lazy to record it, but the animation is just like it was before: your window scales from like 80% size to 100% size... but it takes legit about half a second now when before I would say it was closer to maybe a tenth of a second.
Strange choice... and I do not think it improves the experience...4 -
I hate final designs using only gray scales. I feel they are mockups. I don't want a fucking rainbow but I need color people!10

After learning a bit about alife I was able to write
another one. It took some false starts
to understand the problem, but afterward I was able to refactor the problem into a sort of alife that measured and carefully tweaked various variables in the simulator, as the algorithm
explored the paramater space. After a few hours of letting the thing run, it successfully returned a remainder of zero on 41.4% of semiprimes tested.
This is the bad boy right here:
tracks[14]
[15, 2731, 52, 144, 41.4]
As they say, "he ain't there yet, but he got the spirit."
A 'track' here is just a collection of critical values and a fitness score that was found given a few million runs. These variables are used as input to a factoring algorithm, attempting to factor
any number you give it. These parameters tune or configure the algorithm to try slightly different things. After some trial runs, the results are stored in the last entry in the list, and the whole process is repeated with slightly different numbers, ones that have been modified
and mutated so we can explore the space of possible parameters.
Naturally this is a bit of a hodgepodge, but the critical thing is that for each configuration of numbers representing a track (and its results), I chose the lowest fitness of three runs.
Meaning hypothetically theres room for improvement with a tweak of the core algorithm, or even modifications or mutations to the
track variables. I have no clue if this scales up to very large semiprime products, so that would be one of the next steps to test.
Fitness also doesn't account for return speed. Some of these may have a lower overall fitness, but might in fact have a lower basis
(the value of 'i' that needs to be found in order for the algorithm to return rem%a == 0) for correctly factoring a semiprime.
The key thing here is that because all the entries generated here are dependent on in an outer loop that specifies [i] must never be greater than a/4 (for whatever the lowest factor generated in this run is), we can potentially push down the value of i further with some modification.
The entire exercise took 2.1735 billion iterations (3-4 hours, wasn't paying attention) to find this particular configuration of variables for the current algorithm, but as before, I suspect I can probably push the fitness value (percentage of semiprimes covered) higher, either with a few
additional parameters, or a modification of the algorithm itself (with a necessary rerun to find another track of equivalent or greater fitness).
I'm starting to bump up to the limit of my resources, I keep hitting the ceiling in my RAD-style write->test->repeat development loop.
I'm primarily using the limited number of identities I know, my gut intuition, combine with looking at the numbers themselves, to deduce relationships as I improve these and other algorithms, instead of relying strictly on memorizing identities like most mathematicians do.
I'm thinking if I want to keep that rapid write->eval loop I'm gonna have to upgrade, or go to a server environment to keep things snappy.
I did find that "jiggling" the parameters after each trial helped to explore the parameter
space better, so I wrote some methods to do just that. But what I wouldn't mind doing
is taking this a bit of a step further, and writing some code to optimize the variables
of the jiggle method itself, by automating the observation of real-time track fitness,
and discarding those changes that lead to the system tending to find tracks with lower fitness.
I'd also like to break up the entire regime into a training vs test set, but for now
the results are pretty promising.
I knew if I kept researching I'd likely find extensions like this. Of course tested on
billions of semiprimes, instead of simply millions, or tested on very large semiprimes, the
effect might disappear, though the more i've tested, and the larger the numbers I've given it,
the more the effect has become prevalent.
Hitko suggested in the earlier thread, based on a simplification, that the original algorithm
was a tautology, but something told me for a change that I got one correct. Without that initial challenge I might have chalked this up to another false start instead of pushing through and making further breakthroughs.
I'd also like to thank all those who followed along, helped, or cheered on the madness:

My afternoon has been worse than pulling teeth:
Me: "Hey services admin group, I need a ClientSecret generated."
Services Admin: "We can't do that, but we talked to the original dev team and they can. Go to their Slack channel and someone there will do it for you."
Me: "Hey original dev team, can you create a ClientSecret for me?"
Dev Team: "Does your team lead sign off on this?"
Team Lead: "Give him whatever permission he needs!"
Dev Team: "You should be able to give him whatever permissions he needs"
Team Lead: "I cannot"
Dev Team: "We just gave you permissions to give him permissions"
Team Lead: "I don't know how to give him the permissions he needs. Why didn't you just give him permissions"
Dev Team: "This scales better"2 -
Just to show you.
The overhead between actual SQL requests and the stack :
.Net 6 =>
Web API =>
EntityFramework core 6 =>
(middleware) GraphQl.EntityFramework =>
GraphQl =>
SQL
Seems a lot ? Yep. But actually... that shit just scales. More sql requests will not cost much. And this stack will take care of generating optimal querry better than me by hand.
(These querries on screenshot are fairly complex).
I like it. So, so much checks done for me and front end people love it too ! They don't need to open a tiocket when they need a new field.
So, /adpoted by me.
PS : And pair it with Blazor, miam.1 -
I hate Intellij Idea but it's best option available to develop in Scala. Improvements in VSCode/Metals is my last hope.
The (few) things I NEED from Intellij:
* Very good autocompletion
* Refactoring tools (renaming, auto imports)
* Search tools (find usages, sub/super-types)
The (many) things I hate of Intellij:
* Layout with panel sizes doesn't behave properly and it scales instead of remaining fixed.
* Tedious 2-hands shortcuts makes the right hand to move a lot from the mouse
* Delays and lag in the UI, freezes on garbage collection
* High memory consumption, high CPU usage and generally slow and cumbersome
* The delay in the UI between commands is so that it's accidentally possible to introduce typos
* Can't move tabs around and organize them as I like
* Ugly font rendering and missing typography settings
* Multi-caret implementation as a different editing mode is annoying because requires frequent switching
* Unnatural code folding regions, why method arguments are not folded with the method?
* Unhelpful support forum, sometimes dismissive answers
* Highlighting of current word under the caret doesn't work
* Very slow editor, can't keep spacebar pressed to move text or it hangs!
* Several settings reset at every update. Like the auto fetch of git
* New features are added and enabled by default which is very invasive
* Some of the features mentioned above are really annoying and it's not possible/not trivial to disable them
* It uses its own compile and several times it highlights false positives7 -
It is very hard to handle AIs, you need leading scientists/artists, not managers.
You can't charm your way around its behavioral problems, you can't effectively bully or pull rank on it, and can't threaten it into unemployment.
So, the entire repertoire of the typical (asshole) manager is toast.
The *only* way to handle AI is to lead by example, give unambiguous, comprehensive and very specific instructions, and be always available to guide it through complex, gray-area situations.
Thus, it is not much different than being an actual leader (to a greenhorn and anxious and overreaching junior), but also a programmer (of a raw and unforgiving language like C or COBOL).
Since your typical company mid-level asshole manager won't do those things for dear life, AI will only leverage their incompetence to heights never seen.
By ignoring feedback and misinterpreting instructions, AI will make mistakes (just like a person).
On the wake of those mistakes, AIs have a bias for falsifying evidences and hiding relevant information (just like a bad coworker), and yet are quite persuasive to the innatentive reader (just like your typical manager).
Thus, without a daft hand, AIs will only perform worse when doing the tasks that would otherwise be done by a human.
But that will take time (more than a couple quarters, at least - probably a bit longer than the average tenure of a CEO).
And in this time, the numbers look great - the over eager "aimployee" works tirelessly day and night, seven days a week, takes no breaks, holidays or vacations, asks for no benefits besides a paycheck, have fewer and fewer sick days (maintenance downtimes), always sucks up to its corporate masters and is always ready to take on even more responsibility for (relatively) little extra pay.
Thus the problem only scales up, compounded by the corporate ideal of screwing up workers for no monetary profit, and reluctance to course-correct after investing so much time and hype into this AI bubble.
Thereby, AI is evolving into the corporate super bug that shall erode the already crumbling, stuck-in-the-past "boss mentality" institutions into oblivion.

I hate the elasticsearch backup api.
From beginning to end it's an painful experience.
I try to explain it, but I don't think I will be able to cover it all.
The core concept is:
- repository (storage for snapshots)
- snapshots (actual backup)
The first design flaw is that every backup in an repository is incremental. ES creates an incremental filesystem tree.
Some reasons why this is a bad idea:
- deletion of (older) backups is slow, as newer backups need to be checked for integrity
- you simply have to trust ES that it does the right thing (given the bugs it has... It seems like a very bad idea TM)
- you have no possibility of verification of snapshots
Workaround... Create many repositories as each new repository forces an full backup.........
The second thing: ES scales. Many nodes / es instances form a cluster.
Usually backup APIs incorporate these in their design. ES does not.
If an index spans 12 nodes and u use an network storage, yes: a maximum of 12 nodes will open an eg NFS connection and start backuping.
It might sound not so bad with 12 nodes and one index...
But it get's pretty bad with 100s of indexes and several dozen nodes...
And there is no real limiting in ES. You can plug a few holes, but all in all, when you don't plan carefully your backups, you'll get a pretty f*cked up network congestion.
So traffic shaping must be manually added. Yay...
The last thing is the API itself.
It's a... very fragile thing.
Especially in older ES releases, the documentation is like handing you a flex instead of toilet paper for a wipe.
Documentation != API != Reality.
Especially the fault handling left me more than once speechless...
Eg:
/_snapshot/storage/backup
gives you a state PARTIAL
/_snapshot/storage/backup/_status
gives you a state SUCCESS
Why? The first one is blocking and refers to the backup status itself. The second one shouldn't be blocking and refers to the backup operation.
And yes. The backup operation state is SUCCESS, while the backup state might be PARTIAL (hence no full backup was made, there were errors).
So we have now an additional API that we query that then wraps the API of elasticsearch. With all these shiny scary workarounds like polling, since some APIs are blocking which might lead to a gateway timeout...
Gateway timeout? Yes. Since some operations can run a LONG (multiple hours) time and you don't want to have a ton of open connections hogging resources... You let the loadbalancer kill it. Most operations simply run in ES in the background, while the connection was killed.
So much joy and fun, isn't it?
Now add the latest SMR scandal and a few faulty (as in SMR instead of CMD) hdds in a hundred terabyte ZFS pool and you'll get my frustration level.
PS: The cluster has several dozen terabyte and a lot od nodes. If you have good advice, you're welcome - but please think carefully about this fact.
I might have accidentially vaporized people sending me links with solutions that don't work on large scale TM.2 -
I am having an introspective moment as a junior dev.
I am working in my 3rd company now and have spent the avg amount of time i would spent in a company ( 1- 1.5 years)
I find myself in similar problems and trajectories:
1. The companies i worked for were startups of various scales : an edtech platform, an insurance company (branch of an mnc) and a b2b analytics company
2. These people hire developers based on domain knowledge and not innovative thinking , and expect them to build anything that the PMs deem as growth/engagement worthy ( For eg, i am bad at those memory time optimising programming/ ds/algo, but i can make any kind of android screen/component, so me and people like me get hired here)
3. These people hire new PMs based on expertise in revenue generation and again , not on the basis of innovative thinking, coz most of the time these folks make tickets to experiment with buttons and text colors to increase engagement/growth
4. The system goes into chaos mode soon since their are so many cross operating teams and the PMs running around trying to boss every dev , qa and designer to add their changes in the app.
5. meanwhile due to multiple different teams working on different aspects, their is no common data center with up to date info of all flows, products and features. the product soon becomes a Frankenstein monster.
6. Thus these companies require more and more devs and QAs which are cogs in the system then innovative thinkers . the cogs in the system will simply come, dimwittingly add whatever feature is needed and goto home.
7. the cogs in system which also start taking the pain of tracking the changes and learning about the product itself becomes "load bearing cogs" : i.e the devs with so much knowledge of the product that they can be helpful in every aspect of feature lifecycle .
8. such devs find themselves in no need for proving themselves , in no need for doing innovative work and are simply promoted based on their domain knowledge and impact.
My question is simply this : are we as a dev just destined to be load bearing cogs?
we are doing the work which ideally a manager should be doing, ie maintaining confluence docs with end to end technical as well as business logic info of every feature/flow.
So is that the only definition of a Software Engineer in a technical product?
then how come innovations happen in companies like meta Microsoft google open ai etc?
if i have to guess as a far observer, i would say their diversity in different fields helps them mix and match stuff and lead to innovative stuff.
For eg, the android os team in google has helped add many innovative things in google cloud product and vice versa.
same is with azure and windows . windows is now optomissed to run in cloud machines when at one point it was just a horrible memory hogging and slow pc OS
for small companies, 1 ideology/product/domain is their hero ideology/product/domain .
an insurance company tries to experiment with stuff related to insurances,health,vehicles,and the best innovations they come up with is "lets give user a discount in premium if they do 5000 steps a day for an year".
edtech would say "lets do live streaming for children apart from static videos"
but Android team at google said , "since ai team is doing so well, lets include ai in various system apps and support device level models" ~ a much larger innovation as 2 domains combined to make a product
The small companies are not aiming to be an innovative product, they are just aiming to be a monopoly product. and this is kinda sad2 -
Yo, DevRat! Python is basically the rockstar of programming languages. Here's why it's so dope:
1. **Readability Rules**: Python's code is like super neat handwriting; you don't need a decoder ring. Forget those curly braces and semicolons – Python uses indents to keep things tidy.
2. **Zen Vibes**: Python has its own philosophy called "The Zen of Python." It's like Python's personal horoscope, telling you to keep it simple and readable. Can't argue with cosmic coding wisdom, right?
3. **Tools Galore**: Python's got this massive toolbox with tools for everything – web scraping, AI, web development, you name it. It's like a programming Swiss Army knife.
4. **Party with the Community**: Python peeps are like the coolest party crew. Stuck on a problem? Hit up Stack Overflow. Wanna hang out? GitHub's where it's at. PyCon? It's like the Woodstock of coding, man!
5. **All-in-One Language**: Python isn't a one-trick pony. You can code websites, automate stuff, do data science, make games, and even boss around robots. Talk about versatility!
6. **Learn It in Your Sleep**: Python's like that subject in school that's just a breeze. It's beginner-friendly, but it also scales up for the big stuff.
So, DevRat, Python's the way to go – it's like the coolest buddy in the coding world. Time to rock and code! 🚀🐍💻rant pythonbugs pythonwoes pythonlife python pythonprogramming codinginpython pythonfrustration pythoncode pythonrant pythoncommunity pythondev4 -
I have decided that massive natural selection events are a thing with humans. When resources appear to be getting low a group of people will prepare and wipe out a large portion of consumers. The most straight forward way is to create a crisis and then offer the "only" solution. Make that solution a weapon and you are done. The masses gladly accept the solution. At all times appear benevolent. Silence dissenting voices swiftly. Make the dissenters look like nutters and publicly humiliate them and apply labels to them. Labels are effective because it creates pariahs. People like to not be singled out and called names.
What do you end up with? People who distrust government and the institutions. I don't know how this benefits the orchestrators (how to spell) of the genocide. Perhaps if the numbers are small enough they can just be rounded up and killed by force rather than coercion.
I get the feeling this approach has been used in the past. Like it has been at least tested on smaller scales. Maybe even on past civilizations. Did we learn to do this from space visitors? I wonder.
2021 has certainly been an interesting year. I used to think people were just stupid. This year has confirmed that for me. But I am not sure stupid is the right word. They are certainly book smart. Maybe naive is a better word. I pray and hope 2022 turns out better for people. Maybe they start seeing signs they have been lied to by people they trust. Maybe not. When you are in the matrix it is hard to see through the facade. The matrix feels very real, until it doesn't.

When you’re counting calories, there is nothing more satisfying than eating a bit less than normal every day and watching thermodynamics in her firm inevitability shaving pound after pound off your scales number.
It’s comforting to know that if you’re not losing weight that way, the laws of thermodynamics will have to be rewritten. That ain’t gonna happen any time soon, so you can’t not lose weight.27 -
Artsy friend asked me to make a program to auto add images from folder and layout in refBoard.
Spend time figuring out how the author scales images and setting the XML up. Post wip online and someone asked why not use pureRef... Does all that stuff and more built in...
Thankfully only spent a few hours on it heh... -
Thanks CSS, not sure if I should but I am using ‘vw’ unit for font-size on desktop as it scales according to browser width. It works a treat and saved some shitty reflow breakpoint requirements. Until someone tells me it’s a shit idea, i’m gonna use the fuckr.5
