Oh my god... Storytime.
A customer comes in with I assume is his father or grandfather.
Customer: I need a computer, but without all the internals
Me: So a case?
Customer: Yes, I need a Dell computer outsides, but without the internal components.
Me: Well, we don't have Dell cases, but we sell custom build cases and they come with a power supply.
Customer: *says nothing, but looks interested*
Me: *walks over to the cases to show him* So this is what the cases look like and we have two types, one for a ATX and one for a micro-ATX.
Customer: *still says nothing, but looks at them*
Me: What motherboard do you have at the moment?
Customer: Well, I don't have anything right now, but I'm replacing another computer that didn't work very well. I'm going to be getting some Dell parts to put in here.
Me: O-okay. So this other computer, I'd like to see it in shop to see what's going on with it.
Customer: Oh, you do NOT want to do that. I hooked it up to another computer and it blew it up.
Me: Huh, that's weird. I'd still like to look at it if possible.
Customer: Oh no, it's all wired wrong and... *some bullshit, but stay with me*
Customer: I am the best at technology. My hand has computer parts in it--government funded. *some more bullshit*
Me: Okay... *I try to bring it back around* Well, I'd still like to see the other computer for myself. So you don't have parts for this new build yet, right? You don't know what type of motherboard you have?
Customer: No.
Me: Well, I would get the internals first, so you know what size of case to get, and then get the case.
Customer: Okay. Thank you for your time.
He shook my hand with his "cyborg" hand and I was tempted to say something about "try not to crush my hand," but elected not to. Also during this entire exchange, the old man continuously farted in the background.22 -
When I was in my second semester of college I was tasked with creating a file encrypt/decrypt program. Take in normal textfiles and spit out a new random text and symbols file. I worked on it for two weeks and read up on all different encryption types and stuff. I was so excited when it was done. After it was done compiling I tried it out on its own source code. Encrypto.c and named the output file Encrypto.c 😰 The next thing I did was google " best version control and how to use it."17

I wanted to post a note on devRant community etiquette and rule-breaking behavior we’ve been seeing lately to make clear it will not be tolerated. This is pretty much a rehash of this rant, https://devrant.com/rants/609739/... and also our official rules which I highly encourage people to read: https://devrant.com/rules
I’ve noticed an influx of a select group of members, mostly older users, expressing a distain towards other users or declaring content they dislike “shouldn’t be posted”, “please stop”, etc. If you find yourself about to post that, as per our rules, please don’t. It blatantly violates our rules and we are going to start cracking down on it much more. Whether you have 30k+ points or 10, we will apply the rules fairly to everyone and not give breaks to specific people, which admittedly I’ve done in the past.
If we see this behavior in rants/comments first we will give a warning (and the rant/comment will be deleted) and the next offense is a ban.
A valid question (even though I’ve answered it before) might be why does this need to be a rule? Simply put, it’s a rule for a number of reasons: posts like described try to inflict one’s will upon the entire community (even though we have a Democrat voting process...), they create confusion (almost every time they try to sound official, ex. “Stop doing this”), and beyond those two main reasons, they literally accomplish nothing because they offer no constructive methods of achieving what’s being requested, and only a fraction of the community will actually see it.
Here’s an example of what’s not allowed and what is allowed:
- Allowed: posting an issue on our GitHub issue tracker saying “I really dislike seeing this type of rant in my algo feed, here’s some ideas I have to improve the algo and add more personalization so I can see what I want.”
- Allowed: posting on GitHub issue tracker: “I found this awesome image similarly algo that I think can improve the ‘repost check feature’ - you guys should check it out and see if it might be good”
- Not allowed: “Omg stop shitposting windows update rants and Linux rants I hate them. Go post this type of rant because that’s what everyone really wants to see.”
One is constructive an the other is merely an opinion expressed as an enforcement of a self-made rule on the community and tries to tell other people how they should use devRant.
I cringe when people tell others how to use devRant because without fail when I see those posts, I go through that person’s rant/comment history and I nearly always see them using devRant in some kind of way I disagree with or isn’t exactly what I like to see. But that’s OK. I understand I’m not going to enjoy everything posted and I’m also not going to agree with everything posted. But I think it’s fair for those same people to then lecture on what isn’t appropriate to post on devRant, and it’s even more silly when their posts are sometimes irrelevant to development and the posts they are complaining about are relevant.
In the end, based on the large majority of feedback we get, we want to make devRant a place where everyone feels comfortable expressing themselves and doesn’t have to think about possibly getting ridiculed every time they post and that don’t have people trying to dictate what kind of ideas they are allowed to post. We also realize there’s types of content people don’t enjoy, but telling others not to post it is not the solution. We will soon be launching post type filters that will make filtering rants by post type possible.
Please let me know if you have any questions and thanks for reading.64 -
Two types of people in this world.

Those who press Ctrl+Alt+Del and click on Task Manager.19 -
Seven months ago:
===============
Project Manager: - "Guys, we need to make this brand new ProjectX, here are the specs. What do you think?"
Bored Old Lead: - "I was going to resign this week but you've convinced me, this is a challenge, I never worked with this stack, I'm staying! I'll gladly play with this framework I never used before, it seems to work with this libA I can use here and this libB that I can use here! Such fun!"
Project Manager: - "Awesome! I'm counting on you!"
Six months ago:
====================
Cprn: - "So this part you asked me to implement is tons of work due to the way you're using libA. I really don't think we need it here. We could use a more common approach."
Bored Old Lead: - "No, I already rewrote parts of libB to work with libA, we're keeping it. Just do what's needed."
Cprn: - "Really? Oh, I see. It solves this one issue I'm having at least. Did you push the changes upstream?"
Bored Old Lead: - "No, nobody uses it like that, people don't need it."
Cprn: - "Wait... What? Then why did you even *think* about using those two libs together? It makes no sense."
Bored Old Lead: - "Come on, it's a challenge! Read it! Understand it! It'll make you a better coder!"
Four months ago:
==============
Cprn: - "That version of the framework you used is loosing support next month. We really should update."
Bored Old Lead: - "Yeah, we can't. I changed some core framework mechanics and the patches won't work with the new version. I'd have to rewrite these."
Cprn: - "Please do?"
Bored Old Lead: - "Nah, it's a waste of time! We're not updating!"
Three months ago:
===============
Bored Old Lead: - "The code you committed doesn't pass the tests."
Cprn: - "I just run it on my working copy and everything passes."
Bored Old Lead: - "Doesn't work on mine."
Cprn: - "Let me take a look... Ah! Here you go! You've misused these two options in the framework config for your dev environment."
Bored Old Lead: - "No, I had to hack them like that to work with libB."
Cprn: - "But the new framework version already brings everything we need from libB. We could just update and drop it."
Bored Old Lead: - "No! Can't update, remember?"
Last Friday:
=========
Bored Old Lead: - "You need to rewrite these tests. They work really slow. Two hours to pass all."
Cprn: - "What..? How come? I just run them on revision from this morning and all passed in a minute."
Bored Old Lead: - "Pull the changes and try again. I changed few input dataset objects and then copied results from error messages to assertions to make the tests pass and now it takes two hours. I've narrowed it to those weird tests here."
Cprn: - "Yeah, all of those use ORM. Maybe it's something with the model?"
Bored Old Lead: - "No, all is fine with the model. I was just there rewriting the way framework maps data types to accommodate for my new type that's really just an enum but I made it into a special custom object that needs special custom handling in the ORM. I haven't noticed any issues."
Cprn: - "What!? This makes *zero* sense! You're rewriting vendor code and expect everything to just work!? You're using libs that aren't designed to work together in production code because you wanted a challenge!?? And when everything blows up you're blaming my test code that you're feeding with incorrect dataset!??? See you on Monday, I'm going home! *door slam*"
Today:

Project Manager: - "Cprn, Bored Old Lead left on Friday. He said he can't work with you. You're responsible for Project X now."24 -
There are two types of people :
1. People who do backup
2. People who will start doing backup
Yesterday I advanced from type 2 to type 1 :-/9 -
1. There are 10 types of people in the world: those who understand binary, and those who don't.
2. How many programmers does it take to change a light bulb?
None. It's a hardware problem.
3. A SEO couple had twins. For the first time they were happy with duplicate content.
4. Why is it that programmers always confuse Halloween with Christmas?
Because 31 OCT = 25 DEC
5. Why do they call it hyper text?
Too much JAVA.
6. Why was the JavaScript developer sad?
Because he didn't Node how to Express himself
7. In order to understand recursion you must first understand recursion.
8. Why do Java developers wear glasses? Because they can't C#
9. What do you call 8 hobbits?
A hobbyte
10. Why did the developer go broke?
Because he used up all his cache
11. Why did the geek add body { padding-top: 1000px; } to his Facebook profile?
He wanted to keep a low profile.
12. An SEO expert walks into a bar, bars, pub, tavern, public house, Irish pub, drinks, beer, alcohol
13. I would tell you a UDP joke, but you might not get it.
14. 8 bytes walk into a bar, the bartenders asks "What will it be?"
One of them says, "Make us a double."
15. Two bytes meet. The first byte asks, "Are you ill?"
The second byte replies, "No, just feeling a bit off."
16. These two strings walk into a bar and sit down. The bartender says, "So what'll it be?"

20. There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors.10 -
I’m surrounded by idiots.
I’m continually reminded of that fact, but today I found something that really drives that point home.
Gather ‘round, everybody, it’s story time!
While working on a slow query ticket, I perused the code, finding several causes, and decided to run git blame on the files to see what dummy authored the mental diarrhea currently befouling my screen. As it turns out, the entire feature was written by mister legendary Apple golden boy “Finder’s Keeper” dev himself.
To give you the full scope of this mess, let me start at the frontend and work my way backward.
He wrote a javascript method that tracks whatever row was/is under the mouse in a table and dynamically removes/adds a “.row_selected” class on it. At least the js uses events (jQuery…) instead of a `setTimeout()` so it could be worse. But still, has he never heard of :hover? The function literally does nothing else, and the `selectedRow` var he stores the element reference in isn’t used elsewhere.
This function allows the user to better see the rows in the API Calls table, for which there is a also search feature — the very thing I’m tasked with fixing.
It’s worth noting that above the search feature are two inputs for a date range, with some helpful links like “last week” and “last month” … and “All”. It’s also worth noting that this table is for displaying search results of all the API requests and their responses for a given merchant… this table is enormous.
This search field for this table queries the backend on every character the user types. There’s no debouncing, no submit event, etc., so it triggers on every keystroke. The actual request runs through a layer of abstraction to parse out and log the user-entered date range, figure out where the request came from, and to map out some column names or add additional ones. It also does some hard to follow (and amazingly not injectable) orm condition building. It’s a mess of functional ugly.
The important columns in the table this query ultimately searches are not indexed, despite it only looking for “create_order” records — the largest of twenty-some types in the table. It also uses partial text matching (again: on. every. single. keystroke.) across two varchar(255)s that only ever hold <16 chars — and of which users only ever care about one at a time. After all of this, it filters the results based on some uncommented regexes, and worst of all: instead of fetching only one page’s worth of results like you’d expect, it fetches all of them at once and then discards what isn’t included by the paginator. So not only is this a guaranteed full table scan with partial text matching for every query (over millions to hundreds of millions of records), it’s that same full table scan for every single keystroke while the user types, and all but 25 records (user-selectable) get discarded — and then requeried when the user looks at the next page of results.
What the bloody fucking hell? I’d swear this idiot is an intern, but his code does (amazingly) actually work.
No wonder this search field nearly crashed one of the servers when someone actually tried using it.

"Root, go fix this bug. It'll take you two days."
The "bug" is a feature that was never implemented for one particular payment type.
The code in question is two years old, full of typos, smells, junior-isms, and is convoluted AF. The feature's commit touched 190 files and implemented many other features as well. Thus far, I have been unable to narrow down where this particular feature's code lives for the other payment types, nor which code or payment paths lead to it. Burned out, I can barely focus on the screen, let alone follow its many twisting and dynamically-inferred paths. I hint as to the ticket's scavenger hunt nature during standup.
"But I wrote comments on the ticket telling you exactly where to look to fix it," Thundercunt admonishes in front of the team.
"Sure, you did," Root replies. "You reworded what the original dev had said in the comments 20 minutes prior, and agreed with him. His comments were helpful, but it doesn't tell me how any of it works," she continues.
TC scoffs and closes the meeting.
Root stares blankly, seeing neither code nor screen, questions her life decisions, and recalls the previous tickets she has worked on: nearly every one of them busywork, fixing other people's bugs. Bugs she never could have gotten away with if she tried.
"Why do I put up with this?" She asks. "They don't care, and it's killing me."
But the bills remain, and so must she.
"Fuck my life" she finally decides.20 -
This one is for devs and gamers.
But first some background story.
My girlfriend is special. Not just generically lovey mush mush special. She is 1 in 100 more accurately 1 in 10000. She was born with a rare Congenital Heart Defect {CHD}. Called Truncus Arteriosus or TA for sake of brevity. TA's main thing is the two main arteries going into the heart are fused together and never seperated at birth. It's bad news. There is no cure for this kind of thing. Simply repairs that happen over the course of life.
So here is me. Desperately trying to find a way to get the word about this and the 40 other types of CHD out there in the world. I thought. "What if I make a game..." Not based around the medical jargon but on a level people could understand. I spent the better part of the last six years attending appointments with her and still don't get it. What I do get is her Emotional state. How her CHD causes her to think and feel.
So here is the pitch.
The game is about a girl who is diagnosed at birth with a CHD. She is now in her 20's and has to undergo an open heart surgery to repair the defect. The day comes. She goes under but when she wakes up she find herself in a final fantasy style environment. This new world has a darkness cast over it. She is unknowingly the hero of this world and she has to face off with multiple bosses of varied degrees of evil.
Then after beating these bosses she really wakes up from the surgery. Waking up to the realization that the world she saved was herself. And all the bosses were manifestations of her own internal feelings. Depression, anxiety, hopelessness, Denise, desire and so on.
I would sell this game with the caveat that 2/3 of all profits get split between the Adult Congenital Heart Association and Project Heart. As those are the two main organizations that deal heavily with creating standards of care and raising awareness for CHD survivors.
Thoughts?
Note: I am still learning game dev. This is an eventual goal for me.33 -
I am the new girl. While I’ve been at this company for two years, I’ve only been in my new position a little over a month. I haven’t quite figured out if I am sysadmin or devops yet. It’s a bit all over the place. I am building a new thing at work. I build different types servers and set them on fire frequently as a hobby. This one is a stack I haven’t built before. It wasn’t working. I eventually got to the point where I told the other guy maybe I should consider resigning, I’m not qualified for this job. He said... Finally... now you’re going to figure it out and fix it. The next day, I did find what I kept overlooking and made it work. I guess this is life now.5

aslkfjasf. i've spent 12 hours today (and lots more over the past two days) trying to reproduce a bug that my [sort of] coworker insists is present. I haven't seen any proof of it anywhere, let alone steps to reproduce it.
I've poured through the code, following all of its tangled noodles of madness from start to fuck-this-shit. I've read and reread the pile of demon excrement so many times i can still read the code when i close my eyes. so. not. kidding.
anyway, the coworker person is getting mad because i haven't fixed the bug after days, and haven't even reproduced it yet. This feature is already taking way too fucking long so I totally don't blame him. but urghh it's like trying to unwind a string someone tied into a tight little ball of knots because they were bored.
but i just figured out why I haven't been able to reproduce it.
the stupid fucking unreliable dipshit ex-"i'm a rockstar and my code rocks"-CTO buffoon (aka API Guy, aka the `a=b if a!=b`loody pointless waste of mixed spaces and tabs) that wrote the original APIs ... 'kay, i need to stop for breath.
The dumbfuck wrote the APIs (which I based the new ones on mostly wholesale because wtf messy?), but he never implemented a very fucking important feature for a specific merchant type. It works for literally every type except the (soon-to-be) most common one. and it just so happens that i need that very specific feature to reproduce this bug.
Why is that one specific merchant type handled so differently? No fucking idea.
But exactly how they're handled differently is why I'm so fking pissed off. It's his error checking. (Some) of his functions return different object types (hash, database object, string, nullable bool, ...) depending on what happened. like, when creating a new gift, it (eventually...) either returns a new Gift object or a string error basically saying "ahhh everything's broken again!" -- which is never displayed, compared against, or recorded anywhere, ofc. Here, the API expects a Hash. That particular function call *always* returns a Hash, no matter what happens in the myriad, twisting, and interwoven branches the code could take. So the check is completely pointless.
EXCEPT. if an object associated with another object associated with the passed object (yep) has a type of 8. in which case, one of the methods in the chain returns a PrintQueue that gets passed back up the call stack. implicitly, and nested three levels in. ofc.
And if the API doesn't get its precious Hash, it exclaims that the merchant itself is broken, and tells the user to contact support. despite, you know, the PrintQueue showing that everything worked perfectly. In fact, that merchant's printer will be happily printing away in the background.
All because type checking is this guy's preferred method of detecting errors. (Raise? what's that? OOP? Nah, let's do diverging splintered-monolithic with some Ruby objects thrown in.)
just.
what the crap.
people should keep their mental diarrhea away from their keyboards.
Anyway. the summary of this long-winded, exhaustion-fueled tirade is that our second-most-loved feature doesn't work on our second-most-common merchant type.
and ofc that was the type of merchant i've been testing on. for days. while having both a [semi] coworker and my boss growing increasingly angry at me for my lack of progress.
It's also a huge feature, and the boss doesn't understand that. (can't or won't, idk)
So.
yep.
that's been my week.

Not because I enjoy coding that much, but because there are two types of people:

2) Those who don't know what it is and just assume you're hacking the plane!4 -

Most satisfying bug I've fixed?
Fixed a n+1 issue with a web service retrieving price information. I initially wrote the service, but it was taken over by a couple of 'world class' monday-morning-quarterbacks.
The "Worst code I've ever seen" ... "I can't believe this crap compiles" types that never met anyone else's code that was any good.
After a few months (yes months) and heavy refactoring, the service still returned price information for a product. Pass the service a list of product numbers, service returns the price, availability, etc, that was it.
After a very proud and boisterous deployment, over the next couple of days the service seemed to get slower and slower. DBAs started to complain that the service was causing unusually high wait times, locks, and CPU spikes causing problems for other applications. The usual finger pointing began which ended up with "If PaperTrail had written the service 'correctly' the first time, we wouldn't be in this mess."
Only mattered that I initially wrote the service and no one seemed to care about the two geniuses that took months changing the code.
The dev manager was able to justify a complete re-write of the service using 'proper development methodologies' including budgeting devs, DBAs, server resources, etc..etc. with a projected year+ completion date.
My 'BS Meter' goes off, so I open up the code, maybe 5 minutes...tada...found it. The corresponding stored procedure accepts a list of product numbers and a price type (1=Retail, 2=Dealer, and so on). If you pass 0, the stored procedure returns all the prices.
Code basically looked like this..
public List<Prices> GetPrices(List<Product> products, int priceTypeId)
{
foreach (var item in products)
{
List<int> productIdsParameter = new List<int>();
productIdsParameter.Add(item.ProductID);
List<Price> prices = dataProvider.GetPrices(productIdsParameter, 0);
foreach (var price in prices)
{
if (price.PriceTypeID == priceTypeId)
{
prices = dataProvider.GetPrices(productIdsParameter, price.PriceTypeID);
return prices;
}
* Omitting the other 'WTF?' code to handle the zero price type
}
}
}
I removed the double stored procedure call, updated the method signature to only accept the list of product numbers (which it was before the 'major refactor'), deployed the service to dev (the issue was reproducible in our dev environment) and had the DBA monitor.
The two devs and the manager are grumbling and mocking the changes (they never looked, they assumed I wrote some threading monstrosity) then the DBA walks up..
DBA: "We're good. You hit the database pretty hard and the CPU never moved. Execution plans, locks, all good to go."
<dba starts to walk away>
DevMgr: "No fucking way! Putting that code in a thread wouldn't have fix it"
Me: "Um, I didn't use threads"
Dev1: "You had to. There was no way you made that code run faster without threads"
Dev2: "It runs fine in dev, but there is no way that level of threading will work in production with thousands of requests. I've got unit tests that prove our design is perfect."
Me: "I looked at what the code was doing and removed what it shouldn't be doing. That's it."
DBA: "If the database is happy with the changes, I'm happy. Good job. Get that service deployed tomorrow and lets move on"
Me: "You'll remove the recommendation for a complete re-write of the service?"
DevMgr: "Hell no! The re-write moves forward. This, whatever you did, changes nothing."
DBA: "Hell yes it does!! I've got too much on my plate already to play babysitter with you assholes. I'm done and no one on my team will waste any more time on this. Am I clear?"
Seeing the dev manager face turn red and the other two devs look completely dumbfounded was the most satisfying bug I've fixed.5 -
POSTMORTEM
"4096 bit ~ 96 hours is what he said.
IDK why, but when he took the challenge, he posted that it'd take 36 hours"
As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"
I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
bit lengths
@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.
Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.
What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.
This started cropping up, ironically, right after I posted the thread, whats a man to do?
So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.
Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.
For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.
So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)
x = a/p
y = b/p
1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.
2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.
3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.
Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.
Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.
Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.
I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.
The final result in executable pseudo code (python lol) looks something like the above variables plus
while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
print("factors found!")
print(x)
print(y)
break
w = w + i
Still working but if anyone sees obvious problems I'd LOVE to hear about it.36 -

After two extensive talks with a potential employer (they lasted for hours), I decided to accept the offer, although the salary was ~25% lower than at my previous job. Everything else sounded fantastic and I needed that desperately since at the previous company everything was toxic for years.
These new guys wanted a senior php dev because they had none of them, except only wordpress and drupal people who were not skilled enough to take other types of projects (they called them "custom php"). I liked it and thought I'm gonna shine there and quickly earn a raise because the agency will start earning more by getting projects that they were unable to even bid for.
First day at work and I got assigned to a new Drupal project, although it was supposed to be a simple restful API for a simple iOS app. It could be done in a week or less, with no rushing at all. But it had to be Drupal. And I happened to be around to hear that there is a queue of Drupal projects waiting. After 2 days leaving the office late and having my brain melted by nonsense I was looking at, I quit the job.
No offense to Drupal people, I really do admire you, but I just could not stand it after 8 years "doing custom php". It felt too much like being downgraded. But more than that I was pissed off by the fact that I have been shamelessly lied to and tricked to accept something I clearly said that I dont want.
This happened a year ago. I now earn 2.5x more money than those guys offered and work in a very healthy environment. In the meantime, I heard that the other guys shut their company down.2 -

Rant about devRant.
I hate to see two types of posts:
1. “Haha, i added a WordPress existing theme and charged customer XXXX EUR”, “Idiot customer, I had cross platform app and I charged for each platform”, “lol, they wanted to negotiate the payment, I connected to backdoor and shutdown down their servers”
2. “Why does customer not trust our estimates?” “I told him he does not need to worry about this comparability”, “they are asking about security of the hardened server, are they nuts?
First you treat customers dishonestly and then expect them to trust you and rely on your expertise. Before you constantly complain about the customers - look at yourself guys.10 -

Eval. It can be used responsibly, but most of the times you see it it's because someone fucked up.
C#
Lack of Tuple destructuring in argument specification. Tuples were added, and pattern matching was added, and it's been getting better. The gear grinding starts with how Tuple identity assignment in arguments is handled. Rather than destructuring into the current scope, it coalesces the identity specification into a dot property of whatever the argument name is. This seems like an afterthought given they have ootb support for ignore characters.
Typescript
This will probably be remedied in the next version or two, but Tuple identity forwarding between anonymous scopes normalizes to arrays of union types, because tuples compile to typeless arrays. It's irritating because you end up having to restate the type metadata in functional series even when there is no possibility for any other code branch to have occurred.12 -

I’m adding some fucking commas.
It should be trivial, right?
They’re fucking commas. Displayed on a fucking webpage. So fucking hard.
What the fuck is this even? Specifically, what fucking looney morons can write something so fucking complicated it requires following the code path through ten fucking files to see where something gets fucking defined!?
There are seriously so fucking many layers of abstraction that I can’t even tell where the bloody fucking amount transforms from a currency into a string. I’m digging so deep in the codebase now that any change here will break countless other areas. There’s no excuse for this shit.
I have two options:
A) I convert the resulting magically conjured string into a currency again (and of course lose the actual currency, e.g. usd, peso, etc.), or
B) Refactor the code to actually pass around the currency like it’s fucking intended to be, and convert to a string only when displaying. Like it’s fucking intended to be.
Impossible decision here.
If I pick (A) I get yelled at because it’s bloody wrong. “it’s already for display” they’ll say. Except it isn’t. And on top of that, the “legendary” devs who wrote this monstrosity just assumed the currency will always be in USD. If I’m the last person to touch this, I take the blame. Doesn’t matter that “legendary Mr. Apple dev” wrote it this way. (How do I know? It’s not the first time this shit has happened.) So invariably it’ll be up to me to fix anyway.
But if I pick (B) and fix it now, I’ll get yelled at for refactoring their wonderful code, for making this into too big of a problem (again), and for taking on something that’s “just too much for me.” Assholes. My après Taco Bell bathroom experiences look and smell better than this codebase. But seriously, only those two “legendary” devs get to do any real refactoring or make any architecture decisions — despite many of them being horribly flawed. No one else is even close to qualified… and “qualified” apparently means circle jerking it in Silicon Valley with the other better-than-everyone snobs, bragging about themselves and about one another. MojoJojo. “It was terrible, but it fucking worked! It fucking worked!” And “I can’t believe <blah> wanted to fix that thing. No way, this is a piece of history!” Go fuck yourselves.
So sorry I don’t fit in your stupid club.
Oh, and as an pointed, close-at-hand example of their wonderful code? This API call I’m adding commas to (it’s only used by the frontend) uses a json instance variable to store the total, errors, displayed versions of fees/charges (yes they differ because of course they do), etc. … except that variable isn’t even defined anywhere in the class. It’s defined three. fucking. abstraction. layers. in. THREE! AND. That wonderful piece of smelly garbage they’re so proud of can situationally modify all of the other related instance variables like the various charges and fees, so I can’t just keep the original currency around, or even expect the types to remain the same. It’s global variable hell all over again.
Such fucking wonderful code.
I fucking hate this codebase and I hate this fucking company. And I fucking. hate. them.7 -

Our customers are fucking incredible QA Engineers, holy fuck tits. Every single day, some fucking fuckface finds a way to break this garbage can legacy application that I've spent the last year combing over and patching as I find problems or are otherwise made aware of them.
Honestly, I have some QA background myself, but these types of issues would just absolutely never in a bajillion shitting farting years occur to me to do.
They are masters of breaking shit, I am so FUCKING IMPRESSED. Almost as impressed that this application hasn't been replaced after ten years of bullshit, and that the two massive fucking retards that preceded me didn't just do it the right way by accident or fucking kill themselves out of shame.9 -

I tried finding a gem that would give me a nice, simple diff between two hashes, and also report any missing keys between them. (In an effort to reduce the ridiculous number of update api calls sent out at work.)
I found a few gems that give way too complicated diffs, and they're all several hundred lines long. One of them even writes the diff out in freaking html with colors and everything. it's crazy. Several of the simpler ones don't even support nesting, and another only diffs strings. I found a few possibly-okay choices, but their output is crazy long, and they are none too short, either.
Also, only a few of them support missing keys (since hashes in Ruby return `nil` by default for non-defined keys), which would lead to false negatives.
So... I wrote my own.
It supports diffing anything with anything else, and recurses into anything enumerable. It also supports missing keys/indexes, mixed n-level nesting, missing branches, nil vs "nil" with obvious output, comparing mixed types, empty objects, etc. Returns a simple [a,b] diff array for simple objects, or for nested objects: a flat hash with full paths (like "[key][subkey][12][sub-subkey]") as top-level keys and the diff arrays as values. Tiny output. Took 36 lines and a little over an hour.
I'm pretty happy with myself. 😁6 -
So my friends PC died, since he lives in another country I help him over Signal.
He assembled his own PC a year ago and does a lot of programming for his study. Today Im helping him troubleshoot why his pc does not boot. Does it get into the bootmenu or not? He knows it doesnt. Then I recommend him to try unplugging his graphics card and plug his monitor in the motherboard. I then get a question if there are two HDMI types. Im smiling and think he is messing with me. That must be a displayport. Nope he was serious, he has this HDMI cable that doesnt fit his motherboard.
I sat in a tram and laugh out loud.. Because this is what he send me.
If it was anyone who didnt do anything with computers I didnt think it was laughable, but come on every programmer should know the difference between HDMI and DisplayPort

math be like:
"Addition (often signified by the plus symbol "+") is one of the four basic operations of arithmetic; the others are subtraction, multiplication and division. The addition of two whole numbers is the total amount of those values combined. For example, in the adjacent picture, there is a combination of three apples and two apples together, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" i.e., "3 add 2 is equal to 5".
Besides counting items, addition can also be defined on other types of numbers, such as integers, real numbers and complex numbers. This is part of arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can be performed on abstract objects such as vectors and matrices.
Addition has several important properties. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, the order in which addition is performed does not matter (see Summation). Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication.
Performing addition is one of the simplest numerical tasks. Addition of very small numbers is accessible to toddlers; the most basic task, 1 + 1, can be performed by infants as young as five months and even some members of other animal species. In primary education, students are taught to add numbers in the decimal system, starting with single digits and progressively tackling more difficult problems. Mechanical aids range from the ancient abacus to the modern computer, where research on the most efficient implementations of addition continues to this day."

Seeing on some other posts I wanted to rant about my uni’s computer science community.
Some background: This is a small uni, not like a community college definitely a little bigger. Located somewhere in WV. There is 2-4 girls in every CS class I have had and at least 27-30 guys.
The reason why I mention this is because there is no sense of team work at all. When it comes to exams or projects I take the initiative and make either quizlets (being freaking nice here) share them or take times after school in the library to work on projects. If I have a solution I will share it, I will try to help you in your problem. If I know how to do it of course.
The real issue is all those CS experts that already fixed or finished their programs, the ones on the top of the class. Is as if the moment I ask something related to the project I am already dumb for not have figured it out on my own.
There is the typical CS student that just tries and gives up or just gives up without trying and the other kind of CS student that does that. Doesn’t help anybody else, wants to be on the top all the time.
What I am trying to say here is that it just feels like a competition all the time. (I consider myself in between this two types of students cause I wasn’t born a genius but I do try my ass off on projects) however, I feel like guys see me every new semester in a CS class and think “oh wow how is she still here? Wait did she pass?”
All I say is “yeah I fucking did, with a C or B but here”. So I don’t know, first rant posted 👏🏽🙆🏽♀️10 -

New country, new company, new team, new projects.
I'm supposed to be the TL of a team working on a React project.
A guy in his late 40s celebrates himself as "the senior", he basically just finished watching a youtube thing, React 101 crash course or similar. The other two juniors who did only Wordpress so far venerate him like a god.
The code, of course, is one on the finest pieces of crap I ever had the pleasure to deal with in my life: naturally a bunch of JQuery plugins for everything, no tests, no state management, side effects everywhere, shared state and globals like hell, everything written in ES3/ES5 style, no types, no docs, build and deploy totally manual, deep props drilling at every level... and not to mention the console.log() shipped in prod.
First day, already headache.
Full rewrite start tomorrow.

Two types of people. I see this way to often in the community, and yes, I know this to be true to every industry, but being that I am in I.T I will thus focus just on I.T.
We never know about the situation of other people, we can always tell them that it is natural to be confused at first and they should learn to look at the docs, but to be nasty just for the sake of it, because some screen protects you from catching hands.... that is the legit personification of the fat ugly little troll nerd that is so pathetic that he needs to shit on others over the internet.
Lads, web development can be complex, but it is one of the lowest forms of development, certainly not complex and glamorous enough to act as if we were gods...do we really need to be that mean and nasty?

Mystery of the day: why some developers can't decide on a code style. Let's count:
- two types of brace placements
- three types of assignment spacing (with, without spaces, and aligned with extra space)
- two types of clause spacing
- mixed case in the first char of a variable for no apparent reason(?)
- bonus: unneeded parentheses
At least in ONE thing the person was consistent: no space between parameters!

Difference between Thermal Paste And Thermal Pads
As we all know that the surface of the CPU or a heat sink is not flat. So the uneven surface of both types of equipment give rise to the small gaps, and these small gaps are poor in thermal conductivity, as a result, the Gaming Computer gets heated off quickly.
To fill these gap we require a thermal conductive which delivers the entire heat coming out from the CPU to the heatsink and there comes the role of Thermal paste or Thermal pads for more info about thermal paste see here (https://glinkster.com/best-thermal-...)
But the real question here is which should you chose to avoid heating problems? Is it either thermal paste or thermal pads? So without wasting much time let's get to know what are the basic differences and when you should apply what?
What is the difference between thermal paste and thermal pads?
Thermal paste or thermal compound actually it has a lot of names. Thermal paste is a greasy conductive paste directly applied to the heatsink. It is most commonly used as the interface in between the non-conductive parts for the cooling purpose. A good thermal paste made with the best quality of thermal compound can work well for the system. To apply thermal paste, you have to very careful as you have can also sometimes drop it near to the main CPU. But this is not the only option to fill the holes in between the CPU and the heatsink, there is one more thing that you can use is Thermal Pads.
Thermal Pads
Thermal pads are easy to put as compare to thermal pastes. But they are not as effective as compare to the thermal paste. You will find some stock coolers come with thermal pads as it looks clean. If sometimes you have to replace the heatsink, then you have to remove the pad too. So remember whenever you remove the heatsink ot dismount it, always change the thermal pad.
Common Mistakes you have to avoid
There are some common mistakes that a lot of people make while applying the thermal paste or thermal pads.
1) Never use thermal paste and thermal pads together.
2) But you can use thermal paste on the top of the thermal pads to improve the efficiency.
3) Use of two or three pads altogether can kill the performance of the CPU.

Two big moments today:
1. Holy hell, how did I ever get on without a proper debugger? Was debugging some old code by eye (following along and keeping track mentally, of what the variables should be and what each step did). That didn't work because the code isn't intuitive. Tried the print() method, old reliable as it were. Kinda worked but didn't give me enough fine-grain control.
Bit the bullet and installed Wing IDE for python. And bam, it hit me. How did I ever live without step-through, and breakpoints before now?
2. Remember that non-sieve prime generator I wrote a while back? (well maybe some of you do). The one that generated quasi lucas carmichael (QLC) numbers? Well thats what I managed to debug. I figured out why it wasn't working. Last time I released it, I included two core methods, genprimes() and nextPrime(). The first generates a list of primes accurately, up to some n, and only needs a small handful of QLC numbers filtered out after the fact (because the set of primes generated and the set of QLC numbers overlap. Well I think they call it an embedding, as in QLC is included in the series generated by genprimes, but not the converse, but I digress).
nextPrime() was supposed to take any arbitrary n above zero, and accurately return the nearest prime number above the argument. But for some reason when it started, it would return 2,3,5,6...but genprimes() would work fine for some reason.
So genprimes loops over an index, i, and tests it for primality. It begins by entering the loop, and doing "result = gffi(i)".
This calls into something a function that runs four tests on the argument passed to it. I won't go into detail here about what those are because I don't even remember how I came up with them (I'll make a separate post when the code is fully fixed).
If the number fails any of these tests then gffi would just return the value of i that was passed to it, unaltered. Otherwise, if it did pass all of them, it would return i+1.
And once back in genPrimes() we would check if the variable 'result' was greater than the loop index. And if it was, then it was either prime (comparatively plentiful) or a QLC number (comparatively rare)--these two types and no others.
nextPrime() was only taking n, and didn't have this index to compare to, so the prior steps in genprimes were acting as a filter that nextPrime() didn't have, while internally gffi() was returning not only primes, and QLCs, but also plenty of composite numbers.
Now *why* that last step in genPrimes() was filtering out all the composites, idk.
But now that I understand whats going on I can fix it and hypothetically it should be possible to enter a positive n of any size, and without additional primality checks (such as is done with sieves, where you have to check off multiples of n), get the nearest prime numbers. Of course I'm not familiar enough with prime number generation to know if thats an achievement or worthwhile mentioning, so if anyone *is* familiar, and how something like that holds up compared to other linear generators (O(n)?), I'd be interested to hear about it.
I also am working on filtering out the intersection of the sets (QLC numbers), which I'm pretty sure I figured out how to incorporate into the prime generator itself.
I also think it may be possible to generator primes even faster, using the carmichael numbers or related set--or even derive a function that maps one set of upper-and-lower bounds around a semiprime, and map those same bounds to carmichael numbers that act as the upper and lower bound numbers on the factors of a semiprime.
Meanwhile I'm also looking into testing the prime generator on a larger set of numbers (to make sure it doesn't fail at large values of n) and so I'm looking for more computing power if anyone has it on hand, or is willing to test it at sufficiently large bit lengths (512, 1024, etc).
Lastly, the earlier work I posted (linked below), I realized could be applied with ECM to greatly reduce the smallest factor of a large number.
If ECM, being one of the best methods available, only handles 50-60 digit numbers, & your factors are 70+ digits, then being able to transform your semiprime product into another product tree thats non-semiprime, with factors that ARE in range of ECM, and which *does* contain either of the original factors, means products that *were not* formally factorable by ECM, *could* be now.
That wouldn't have been possible though withput enormous help from many others such as hitko who took the time to explain the solution was a form of modular exponentiation, Fast-Nop who contributed on other threads, Voxera who did as well, and support from Scor in particular, and many others.
Thank you all. And more to come.

I've been wondering this for a while now, but how are senior programmers able to (or at least seem to) remember all the code for all the different languages with all the different syntax?
Let me explain: From my experience there's usually two types of thinkers, there's the memorizers, and the logical thinkers. Its usually the difference between people good at history and people good at math. So considering that most programmers would need to be able to think logically (to problem solve obviously), how do they remember all this different code? I always forget the small details which I have to look back at earlier code to see how it was done (Especially annoying for written exams where we have to remember all the code and how to use it)7 -

Not as much of a rant as a share of my exasperation you might breathe a bit more heavily out your nose at.
My work has dealt out new laptops to devs. Such shiny, very wow. They're also famously easy to use.
.

My arse.

I got the laptop, transferred the necessary files and settings over, then got to work. Delivered ticket i, delivered ticket j, delivered the tests (tests first *cough*) then delivered Mr Bullet to Mr Foot.
Day 4 of using the temporary passwords support gave me I thought it was time to get with department policy and change my myriad passwords to a single one. Maybe it's not as secure but oh hell, would having a single sign-on have saved me from this.
I went for my new machine's password first because why not? It's the one I'll use the most, and I definitely won't forget it. I didn't. (I didn't.) I plopped in my memorable password, including special characters, caps, and numbers, again (carefully typed) in the second password field, then nearly confirmed. Curiosity, you bastard.
There's a key icon by the password field and I still had milk teeth left to chew any and all new features with.
Naturally I click on it. I'm greeted by a window showing me a password generating tool. So many features, options for choosing length, character types, and tons of others but thinking back on it, I only remember those two. I had a cheeky peek at the different passwords generated by it, including playing with the length slider. My curiosity sated, I closed that window and confirmed that my password was in.
You probably know where this is going. I say probably to give room for those of you like me who certifiably. did. not.
Time to test my new password.

Ahh fuck, I can't believe I've done this, but going to support is for pussies. I'll put this by the rest of the fire, I can work on my old laptop.
Day starts getting late, gotta go swimming soonish. Should probably solve the problem. Cue a whole 40 minutes trying my 15 or so different passwords and their permutations because oh heck I hope it's one of them.
I talk to a colleague because by now the "days since last incident" counter has been reset.
"Hello there Ryan, would you kindly go on a voyage with me that I may retrace my steps and perhaps discover the source of this mystery?"
"A man chooses, a slave obeys. I choose... lmao ye sure m8, but I'm driving"
We went straight for the password generator, then the length slider, because who doesn't love sliding a slidey boi. Soon as we moved it my upside down frown turned back around. Down in the 'new password' and the 'confirm new password' IT WAS FUCKING AUTOCOMPLETING. The slidey boi was changing the number of asterisks in both bars as we moved it. Mystery solved, password generator arrested, shit's still fucked.
Bite the bullet, call support.
"Hi, I need my password resetting. I dun goofed"

Gotta be punctual for swimming, got two whole lengths to do and a sauna to sit in.

"Yeah no problem someone will be down in the morning."

There goes my weekend (looong weekend, bank holiday plus day flexi-time) where I could have shown off to my girlfriend the quality at which this laptop can play all our favourite animé, and probably get remind by her that my personal laptop has an i2350u with integrated graphics.
TODAY. (Part is unrelated, but still, ugh.)
Go to work. Ten minutes away realise I forgot my door pass.
Bollocks.
Go get a temporary pass (of shame).
Go to clock in. My fob was with my REAL pass.
What the wank.
Get to my desk, nobody notices my shame. I'm thirsty. I'll have the bottle from my drawer. But wait, what's this? No key that usually lives with my pass? Can't even unlock it?
No thanks.
Support might be able to cheer me up. Support is now for manly men too.
*Knock knock*
"Me again"
"Yeah give it here, I've got the code"
He fixes it, I reset my pass, sensibly change my other passwords.
Or I would, if the internet would work.
It connects, but no traffic? Ryan from earlier helps, we solve it after a while.
My passwords are now sorted, machine is okay, crisis resolved.
*THE END*
If you skipped the whole thing and were expecting a tl;dr, you just lost the game.
Otherwise, I absolve you of having lost the game.

I need some advice here... This will be a long one, please bear with me.
First, some background:
I'm a senior level developer working in a company that primarily doesn't produce software like most fast paced companies. Lots of legacy code, old processes, etc. It's very slow and bureaucratic to say the least, and much of the management and lead engineering talent subscribes to the very old school way of managing projects (commit up front, fixed budget, deliver or else...), but they let us use agile to run our team, so long as we meet our commitments (!!). We are also largely populated by people who aren't really software engineers but who do software work, so being one myself I'm actually a fish out of water... Our lead engineer is one of these people who doesn't understand software engineering and is very types when it comes to managing a project.
That being said, we have this project we've been working for a while and we've been churning on it for the better part of two years - with multiple changes in mediocre contribution to development along the way (mainly due to development talent being hard to secure from other projects). The application hasn't really been given the chance to have its core architecture developed to be really robust and elegant, in favor of "just making things work" in order to satisfy fake deliverables to give the customer.
This has led us to have to settle for a rickety architecture and sloppy technical debt that we can't take the time to properly fix because it doesn't (in the mind of the lead engineer - who isn't a software engineer mind you) deliver visible value. He's constantly changing his mind on what he wants to see working and functional, he zones out during sprint planning, tries to work stories not on the sprint backlog on the side, and doesn't let our product owner do her job. He's holding us to commitments we made in January and he's not listening when the team says we don't think we can deliver on what's left by the end of the year. He thinks it's reasonable to expect us to deliver and he's brushing us off.
We have a functional product now, but it's not very useful yet and still has some usability issues. It's still missing features, which we're being put under pressure to get implemented (even half-assed) by the end of the year.
TL;DR
Should I stand up for what I know is the right way to write software and push for something more stable sometime next year or settle for a "patch job" that we *might* deliver that will most definitely be buggy and be harder to maintain going forward? I feel like I'm fighting an uphill battle in trying to write good quality code in lieu of faster results and I just can't get behind settling for crap just because.9 -

The "stochastic parrot" explanation really grinds my gears because it seems to me just to be a lazy rephrasing of the chinese room argument.
The man in the machine doesn't need to understand chinese. His understanding or lack thereof is completely immaterial to whether the program he is *executing* understands chinese.
It's a way of intellectually laundering, or hiding, the ambiguity underlying a person's inability to distinguish the process of understanding from the mechanism that does the understanding.
The recent arguments that some elements of relativity actually explain our inability to prove or dissect consciousness in a phenomenological context, especially with regards to outside observers (hence the reference to relativity), but I'm glossing over it horribly and probably wildly misunderstanding some aspects. I digress.
It is to say, we are not our brains. We are the *processes* running on the *wetware of our brains*.
This view is consistent with the understanding that there are two types of relations in language, words as they relate to real world objects, and words as they relate to each other. ChatGPT et al, have a model of the world only inasmuch as words-as-they-relate-to-eachother carry some information about the world as a model.
It is to say while we may find some correlates of the mind in the hardware of the brain, more substrate than direct mechanism, it is possible language itself, executed on this medium, acts a scaffold for a broader rich internal representation.
Anyone arguing that these LLMs can't have a mind because they are one-off input-output functions, doesn't stop to think through the implications of their argument: do people with dementia have agency, and sentience?
This is almost certain, even if they forgot what they were doing or thinking about five seconds ago. So agency and sentience, while enhanced by memory, are not reliant on memory as a requirement.
It turns out there is much more information about the world, contained in our written text, than just the surface level relationships. There is a rich dynamic level of entropy buried deep in it, and the training of these models is what is apparently allowing them to tap into this representation in order to do what many of us accurately see as forming internal simulations, even if the ultimate output of that is one character or token at a time, laundering the ultimate series of calculations necessary for said internal simulations across the statistical generation of just one output token or character at a time.
And much as we won't find consciousness by examining a single picture of a brain in action, even if we track it down to single neurons firing, neither will we find consciousness anywhere we look, not even in the single weighted values of a LLMs individual network nodes.
I suspect this will remain true, long past the day a language model or other model merges that can do talk and do everything a human do intelligence-wise.31 -
So last week I really fucked up
I had this new implementation that was supposedly to be integrating smoothly into the rest of the service. It depended on a serialized model made by a data scientist. I test it in local, in QA environment: no problem.
So, Friday, 4pm, I decide to deploy to production. I check once from the app: the service throw an error. Panic attack, my chief is at my desk, we triy to understand what went wrong. I make calls with cUrls: no problem. Everything seems fine. I recheck from the app again: no problem.
We dedice to let it in prod, as the feature work. I go get some beers with the guys, to celebrate the deploy.
Fast-forward the next morning, 11am, my phone ring: it's a colleague of my chief. "Please check Slack, a client is trying to use the feature, it's broken"
FUUUUUUUUUUUUCK!!!
Panic attack again. I go to the computer, check the errors: two types of errors. One I can fix, the other from a missing package on the machine that the data guy used.
Needless to say, I had a fairly good weekend.
Lessons learned:
- make sure Dev, QA and Prod are exactly the same (use Ansible or Container)
- never deploy on a Friday afternoon if you don't have a quick way to revert1 -
Oh I have quite a few.
#1 a BASH script automating ~70% of all our team's work back in my sysadmin days. It was like a Swiss army knife. You could even do `ScriptName INC_number fix` to fix a handful of types of issues automagically! Or `ScriptName server_name healthcheck` to run HW and SW healthchecks. Or things like `ScriptName server_name hw fix` to run HW diags, discover faulty parts, schedule a maintenance timeframe, raise a change request to the appropriate DC and inform service owners by automatically chasing them for CHNG approvals. Not to mention you could `ScriptName -l "serv1 serv2 serv3 ..." doSomething` and similar shit. I am VERY proud of this util. Employee liked it as well and got me awarded. Bought a nice set of Swarowski earrings for my wife with that award :)
#2 a JAVA sort-of-lib - a ModelMapper - able to map two data structures with a single util method call. Defining datamodels like https://github.com/netikras/... (note the @ModelTransform anno) and mapping them to my DTOs like https://github.com/netikras/... .
#3 a @RestTemplate annptation processor / code generator. Basically this dummy class https://github.com/netikras/... will be a template for a REST endpoint. My anno processor will read that class at compile-time and build: a producer (a Controller with all the mappings, correct data types, etc.) and a consumer (a class with the same methods as the template, except when called these methods will actually make the required data transformations and make a REST call to the producer and return the API response object to the caller) as a .jar library. Sort of a custom swagger, just a lil different :)
I had #2 and #3 opensourced but accidentally pushed my nexus password to gitlab. Ever since my utils are a private repo :/3 -
The process of making my paging MIDI player has ground to a halt IMMEDIATELY:
Format 1 MIDIs.
There are 3 MIDI types: Format 0, 1, and 2.
Format 0 is two chunks long. One track chunk and the header chunk. Can be played with literally one chunk_load() call in my player.
Format 2 is (n+1) chunks long, with n being defined in the header chunk (which makes up the +1.) Can be played with one chunk_load() call per chunk in my player.
Format 1... is (n+1) chunks long, same as Format 2, but instead of being played one chunk at a time in sequence, it requires you play all chunks
AT THE SAME FUCKING TIME.
65534 maximum chunks (first track chunk is global tempo events and has no notes), maximum notes per chunk of ((FFFFFFFFh byte max chunk data area length)/3 = 1,431,655,763d)/2 (as Note On and Note Off have to be done for every note for it to be a valid note, and each eats 3 bytes) = 715,827,881 notes (truncated from 715,827,881.5), 715,827,881 * 65534 (max number of tracks with notes) = a grand total of 46,911,064,353,454 absolute maximum notes. At 6 bytes per (valid) note, disregarding track headers and footers, that's 281,466,386,120,724 bytes of memory at absolute minimum, or 255.992 TERABYTES of note data alone.
All potentially having to be played
ALL
AT
ONCE.
This wouldn't be so bad I thought at the start... I wasn't planning on supporting them.
Except...
>= 90% of MIDIs are Format 1.
Yup. The one format seemingly deliberately built not to be paged of the three is BY FAR the most common, even in cases where Format 0 would be a better fit.
Guess this is why no other player pages out MIDIs: the files are most commonly built specifically to disallow it.
Format 1 and 2 differ in the following way: Format 1's chunks all have to hit the piano keys, so to speak, all at once. Format 2's chunks hit one-by-one, even though it can have the same staggering number of notes as Format 1. One is built for short, detailed MIDIs, one for long, sparse ones.
No one seems to be making long ones.6 -
So I've created this account specifically for this rant. I usually just browse anonymously.
I've recently been hired in a big company that is one of the biggest Microsoft users in the world and my essentially revolves on making it easier for our collaborators to work with SharePoint (and other ms software)
Never in my life have I hit that much of a roadblock. So for the past week I've been trying to integrate what Ms calls webparts. And to modify the default webparts Ms provides you need to their properties (or Metadata). Except here's the big problem these are NOT documented anywhere (unless I failed to find it, if you do know where it is documented please HMU), so I've found myself trying to reverse engineer the js scripts that are served with SharePoint to figure out what the webpart properties are called and what type of data they are! I've been going through endless github repos using the CSOM nuget package (it's the library everyone uses to interact with SharePoint) and I finally found out about this other library called PnP which is a wrapper around CSOM that makes it easier to use. That wrapper has a way for me to load existing page and look at the properties of existing webparts. So here I thought it was the end of my suffering and I could finally get an idea of what it should be. Turns out this method doesn't work because one of the dependencies it has has had breaking changes and they still updated it even though it breaks their code! So for the past two days I've been trying random combinations of key values with different data types and json serialization methods.
Oh and yeah I've also looked at all the http calls via the chrome network tab, the metadata is not served as an individual file but is computed by Ms servers when they're serving you their html files.
So uh yeah run from CSOM if you can..3 -
Today on forgotten games – Vangers.
Even though the game is extremely hard and very, very frustrating, it somehow has an ability to make you obsessed with it. A very complex pieces of information, either carefully crafted or accidentally emerged from the void, delivered straight to your brain, making you an addict. If you play it and not delete it after five minutes, there is no way back – you better get used to new, different you.
There are many hard but addictive games based on simple mechanics, but Vangers is a different story. Compared to Vangers, Dark Souls seems nice, simple and easy casual game.
One can easily imagine "the hardest game possible", but all of them simply makes you delete the game and not to play it at all. Vangers precisely balance over this, achieving a very fragile equilibrium, being hard enough to frustrate you like no other game does, but not hard enough to simply make you quit instantly. While doing so, the game makes you a junkie, addicted to its eerie psychedelic nature.
This game spits in your face. This game makes you a slave, a desperate addict. All of your previous gaming skill, and speedrun experience doesn't matter.
The plot roughly goes like this: humans fucked up while experimenting with portals and accidentally discovered an advanced hivemind race. Trying to escape they fuck up spacetime and the two incompatible civilizations annihilate each other, creating a primal soup of creatures, from which the whole new world emerges. So there are many different strange creatures trying to survive in fucked spacetime where incompatible worlds are forcefully fused together, and you are the Vanger, one of many other Vangers trying to figure out what they are and how they was created.
The game features a voxel, fully-destructible world mapped on a torus. The game lore and terminology are extremely complex, and no one will explain it to you, you have to figure everything out yourself. Skip the dialog and no one will repeat it, you're on your own now.
Every playthrough is different. There are very many game mechanics and play styles available.
Everything in the game including complex rendering engine was written in C and Assembler back in 1998.
There are two types of Vangers players: the ones who was able to escape early and the ones who think that Vangers is the best game of all time. This says it all.
Last warning – DON'T PLAY THIS GAME. You better watch some playthrough on youtube.

Major rant incoming. Before I start ranting I’ll say that I totally respect my professor’s past. He worked on some really impressive major developments for the military and other companies a long time ago. Was made an engineering fellow at Raytheon for some GPS software he developed (or lead a team on I should say) and ended up dropping fellowship because of his health. But I’m FUCKING sick of it. So fucking fed up with my professor. This class is “Data Structures in C++” and keep in mind that I’ve been programming in C++ for almost 10 years with it being my primary and first language in OOP.
Throughout this entire class, the teacher has been making huge mistakes by saying things that aren’t right or just simply not knowing how to teach such as telling the students that “int& varOne = varTwo” was an address getting put into a variable until I corrected him about it being a reference and he proceeded to skip all reference slides or steps through sorting algorithms that are wrong or he doesn’t remember how to do it and saying, “So then it gets to this part and....it uh....does that and gets this value and so that’s how you do it *doesnt do rest of it and skips slide*”.
First presentation I did on doubly linked lists. I decided to go above and beyond and write my own code that had a menu to add, insert at position n, delete, print, etc for a doubly linked list. When I go to pull out my code he tells me that I didn’t say anything about a doubly linked list’s tail and head nodes each have a pointer pointing to null and so I was getting docked points. I told him I did actually say it and another classmate spoke up and said “Ya” and he cuts off saying, “No you didn’t”. To which I started to say I’ll show you my slides but he cut me off mid sentence and just yelled, “Nope!”. He docked me 20% and gave me a B- because of that. I had 1 slide where I had a bullet point mentioning it and 2 slides with visual models showing that the head node’s previousNode* and the tail node’s nextNode* pointed to null.
Another classmate that’s never coded in his life had screenshots of code from online (literally all his slides were a screenshot of the next part of code until it finished implementing a binary search tree) and literally read the code line by line, “class node, node pointer node, ......for int i equals zero, i is less than tree dot length er length of tree that is, um i plus plus.....”
Professor yelled at him like 4 times about reading directly from slide and not saying what the code does and he would reply with, “Yes sir” and then continue to read again because there was nothing else he could do.
Ya, he got the same grade as me.
Today I had my second and final presentation. I did it on “Separate Chaining”, a hashing collision resolution. This time I said fuck writing my own code, he didn’t give two shits last time when everyone else just screenshot online example code but me so I decided I’d focus on the PowerPoint and amp it up with animations on models I made with the shapes in PowerPoint. Get 2 slides in and he goes,
Prof: Stop! Go back one slide.
Me: Uh alright, *click*
(Slide showing the 3 collision resolutions: Open Addressing, Separate Chaining, and Re-Hashing)
Prof: Aren’t you forgetting something?
Me: ....Not that I know of sir
Prof: I see Open addressing, also called Open Hashing, but where’s Closed Hashing?
Me: I believe that’s what Seperate Chaining is sir
Prof: No
Me: I’m pretty sure it is
*Class nods and agrees*
Prof: Oh never mind, I didn’t see it right
Get another 4 slides in before:
Prof: Stop! Go back one slide
Me: .......alright *click*
(Professor loses train of thought? Doesn’t mention anything about this slide)
Prof: I er....um, I don’t understand why you decided not to mention the other, er, other types of Chaining. I thought you were going to back on that slide with all the squares (model of hash table with animations moving things around to visualize inserting a value with a collision that I spent hours on) but you didn’t.
(I haven’t finished the second half of my presentation yet you fuck! What if I had it there?)
Me: I never saw anything on any other types of Chaining professor
Prof: I’m pretty sure there’s one that I think combines Open Addressing and Separate Chaining
Me: That doesn’t make sense sir. *explanation why* I did a lot of research and I never saw any other.
Prof: There are, you should have included them.
(I check after I finish. Google comes up with no other Chaining collision resolution)
He docks me 20% and gives me a B- AGAIN! Both presentation grades have feedback saying, “MrCush, I won’t go into the issues we discussed but overall not bad”.
Thanks for being so specific on a whole 20% deduction prick! Oh wait, is it because you don’t have specifics?
Bye 3.8 GPA

Let's call her Silvia.
Silvia debugs her code by whispering it out loud: "so if this variable is two, then..."
Everyone thinks Silvia is great. But she asks for help whenever she runs up against the simplest of problems: "I have never worked with this library/dependency before!"
(Well, that's kind of the nature of open source if you ask me.)
Silvia types with superbly heavy fingers, making sure we can hear every keystroke, especially when she hits return.
I think Silvia overcompensates for something.2 -

I'm fixing our wrapper for API calls. The typescript for it was nice and simple, except that halfway through it casted almost everything as `any` and then hand-typed the expected return type :)))
Took me almost two weeks to work through that wretched piece of code, I managed to get the types actually correct... but now it started to catch incorrect calls, so I have to go through quite a lot of files to fix the references. But the worst part?
Now it breaks unit tests.
Turns out, multiple frontend unit tests DID NOT MOCK API CALLS AT FUCKJNG ALL HGGHGGHHHHHH. I WONDER WHY THE TESTS WERE TAKING SO FUCKING LONG TO RUN. I AM FUCKING FROTHING AT MOUTH AND I MIGHT NEED TO BE PUT DOWN OR I WILL START BITING PEOPLE3 -

The ridiculous and shameful story of how simply "installing Windows" saved my hard drive from the garbage.
(Also update on https://devrant.com/rants/3105365/)
It started with my root partition turning read-only all of a sudden. Some quick search suggested that I should check the sanity of my hard drive, by running a SMART test, which failed of course. I backed up my data using ddrescue and ran a badblocks over the whole thing, which found around 800 unreadable blocks in a row. I was ready to bid farewell to my drive, but as a last resort, instead of the trash, I brought it to this place where they claimed they can repair the damaged hard drives by "surgery".
To my surprise, they returned my drive the next week, saying it is all well now, and charged me 1/8 the price of a new drive, with a refund guarantee if there was a problem in two days. There was a problem right there: I ran another SMART test which failed again, and also the faulty blocks were still unreadable! So I stormed the place and called for my refund, showing the failed SMART report. The only answer I would get from the staff was "Have you tried installing Windows?".
I usually try to be patient in such situations; I really don't like to declare publicly that "not everyone uses that stinky piece of rotten software you call an OS", but their suggestion seemed totally irrelevant! I got all types of IO errors all over the damn thing and they told me to install Windows. Why? Because this was the only test they would rely on. At last I managed to meet the "technician" there and showed him the IO errors: tried to read the bad sectors with dd and failed. He first mumbled somethings like "Have you checked the connector?" or "Are these the same blocks?", but after he ran out of bullshit, he said "Why don't you just install Windows first and see if that helps?" and I was ready to explode in his face!
"You test drives by installing Windows, just because it will make a nasty NTFS partition and probably does an fsck? If you shut your mouth for a sec and open your eyes you'll see this is a shit load of IO errors we got here: You can't install Windows, you can't even make an NTFS here, because it will try to zero-the-fuck-out the damn partition and it will face the same fucking IO error that I'm showing you right now in almost one single fucking system call!"
"I don't know this kind of test you are using. We have our own tests and they've passed successfully. So all I can do is to give you a Windows CD if you want."
"I don't need a Windows CD. I will just try to make an NTFS partition on the error spot and I will fail."
"Ok. Then call me when your done."
I was angry, not only because I felt they're just trying to avoid a refund, but also because I knew I've lost my drive. But just with hope that I could get my money back, I made a small partition over the error spot and ran `mkfs.ntfs` on it. I was ready to show the failure to the guy, but I looked more precisely and saw that "the filesystem was created successfully!" I was sure something is nor write. I then successfully mounted the new partition, write over it and read it again. I even dd'ed the blocks again, and this time there was no IO error. All of a sudden everything was fine.
I didn't know what happened. Maybe it just needed a write, while I'd just tried to read from those blocks. But anyway, I didn't called the technician guy again. I just thanked one of the staff there and said that my problem was solved. I then ran a successful SMART test and then restored my backup. Ridiculous like that.
I'm still not sure if my drive will continue to live with no more problems. I also have no explanation for what happened. (I appreciate any help on this https://superuser.com/questions/...) But I really like to see the look on the poor guy's face when he finds out that trying to install Windows just saved my ass!11 -
If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:
This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...
Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?
Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...
All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).
So what other options are there for making plugins in Go?
There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...
Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...
Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.
Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.
As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...

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 -
How do you get over the bad times? I keep having to work with shitty legacy systems that were written in perl and flash in the 90s, but my boss keeps telling me "No" on redoing some of the bigger stuff even though it is really needed. I mean, that is your goal here, right? Rebuilding this POS? FFS you still stored passwords in plain text twoo weeks ago! But no, you's rather dig around in Perl than upset some random user because his fucking interface looks different.
But then I also have to work with another system that I could redo in Cake/Laravel in two weeks (it's literally getting and writing data to one table, so two views and user auth), and the previous dev just... made a huge mess. I mean, why would you need to post data asynchronously when it's this one stupid form ? Just do a regular form submit? And the system is really not suitable for extending, because everything is in the database, EVERYTHING! Like, html form inputs? So to add a simple input to the template I have to create a new input type in the types table and then add that to the form structure table? Only to have the input checked by fucking regex? REGEX! Why? Seriously, this is not some high end CMS that needs this level of code reusability No. This is a simple fucking form.
And I can't get it to work. No documentation of course. No comments, either. All of this makes me feel like I'm just the shittiest dev ever. I feel dumb, and useless. Haven't turned on my private PC in weeks because I see no reason to work on any of my own stuff.
I used to have a job, working with Magento and Wordpress. And yeah, it was horrible, it was chaos, but it was fun and I was great at it. I bent that motherfucking system to fit my needs. People respected my opinion, they were convinced I could program this and that, and I proved them right. Did I make mistakes? Hell yeah. Did I give up? Fuck no!
But now, I just feel like I can't even write a simple fucking form any more. I'm just so close to giving up on development as a whole, even though I love it so much.5 -
proxying youtube
today I thought writing a quick project, a youtube proxy server, as in, you browse localhost:<PORT> and youtube comes in the response.
this is not rocket science as proxy servers have around for a long time.
I thought it'd be interesting to code it in userland, as opposed to "systemland".
And 50 lines of code and some minor hurdles later I see youtube "running" in localhost.
Although youtube didn't just work as usual since the videos don't actually come from youtube.com, but from googlevideo.com instead. And my browser, expectably, enforces CORS and forbids any requests to it.
At that point I started to think of ways to somehow proxy googlevideo.com too. But the solutions are not at all trivial.
Then I thought what was the payoff of all this. I tried to proxy serve youtube out of curiosity, and sure thing, you can do it.
But what problem would proxying youtube solve? Maybe I should think in a fuller way what are the problems I have with youtube.
One issue I have is the exposure, discoverability. To explain it, let's say I have been watching a very, very big amount of videos as of today.
Personally I would expect youtube to understand very well by now what my tastes are, what do I want to watch and what I do NOT want to watch.
Notice that I am very black and white, and I do not have much interest in watching certain types of videos.
It could be true that if my expectations of how youtube should work became reality then youtube recommendations would become polarizing or echo chambering.
But that is my decision though, and the problem with youtube is that it's seemingly forcing a single recommendations algorithm onto everyone.
Some people are more open minded and want to watch EVERYTHING, and a lot of people don't.
But users aren't deciding what they should get recommended. Youtube is making that decision for them. And it sure feels like it's trying to maximize ad revenue.
I for one don't give two flying fucks about pranks or diva youtubers. Yet youtube is adamant in presenting some of these to me.
Now, trying to come up with a solution for this is really non trivial. It would definitely require some youtube mining, or some kind of network so as to not get rate limited when mining, and even then you still have to think of how a good recommendation system would work.
I think the implementation of all that would be too much for me (time and skill wise). But I think it's fun to at least try to outline how recommendations could work.
I would very much prefer that when youtube recommended something, at least it has some number of confidence meaning how much would I like that video, so at least I know what to expect.
It should also have some indicators like what is the mood of the video. As in, sometimes I watch youtube in the mood of learning, like programming videos, but most of the time I watch to get entertained.
These ideas are just brainstorms and could be terrible on reproduction, but I'd like to hear what ideas can some of the people here can come up with.2 -

At least it balances out!5 -
I'm shitting there hammering out some code butchering some real problems when I suddenly realise I'm surrounded. I look around and yes it's the bloody committee.
The committee is what I call the rest of the department and it is dominated by the old guard which comprises of the programmers that have been around for longer.
None of the old guard can program particularly well but because they had been around the longest they'd all grown senior. The committee had free reign but anyone else doing anything differently has to get approval from the committee.
The only way to code otherwise was to copy and paste existing code then to primarily rename things. If anyone did anything that hadn't been seen before then it would have to be approved by the committee. Individual action was not permitted unless you were old guard.
I swept my headphones away expecting it to be something unimportant. It was.
First things first they announce. We're going to add extraneous commas to the last element of all possible lists separated by comma including parameters or so they say. Ask but why so I do.
Because the language now supports it. They added support for it so it must be the right way someone proclaimed. Does it? I didn't realise we were waiting for it. Why do we want it though?
Didn't you hear? It's all over the blogosphere. It massively improves merge requests. But how I ask?
Five minutes later I grow tired of the chin stroking, elbow harnessing, slanted gazes into the yonder and occasionally hearing maybe its because and ask if they mean when you for example add an element the last element registers as changed from adding a comma. Turns out that's all it is.
How often do we see that tiny distraction and isn't it pointless to make the code ugly just for a tiny transient reduction in diff noise I ask. Everyone's stumped. This went on and on and got worse and worse. But it makes moving things around easy half of them say in unison like the bunch of slobs that they are. I mean really. It doesn't make expanding and contracting statements from multiline to single line easy and it's such a stupid thing. Is that all they do all day? Move multi-line method parameters up and down all day? If their coding conventions weren't totally whack they wouldn't have so many multiline method prototypes with stupid amounts of parameters with stupidly long types and names. They all use the same smart IDE which can also surely handle fixing the last comma and why is that even a concern given all the other outrageously verbose and excessive conventions for readability?
But you know what, who cares, fine, whatever. Lets put commas all over the shop and then we can all go to the pub and woo the ladies with how cool and trendy we are up to date with all the latest trends and fashions then we go home with ten babes hanging off each arm and get so laid we have to take a sick day the following to go to the STD clinic. Make way for we are conformists.
But then someone had to do it. They had to bring up PSR. Yes, another braindead committee that produces stupid decisions. Should brackets be same line or next line, I know, lets do both they decided. Now we have to do PSR and aren't allowed to use sensible conventions.
But why, I ask after explaining it's actually quite useful as a set of documents we can plagiarise as a starting point but then modify but no, we have to do exactly what PSR says. We're all too stupid apparently you see. Apparently we're not on their level. We're mere mortals. The reason or so I'm told, is so that anyone can come in and is they know PSR coding styles be able to read and write the code. That's not how it works. If you can't adjust to a different style, a more consistent style, that's not massively bizarre or atypical but rather with only minor differences from standard styles, you're useless. That's not even an argument, it's a confession that you've got a lump of coal where your brain's supposed to be.
Through all of this I don't really care because I long ago just made my own code generators or transpilers that work two ways and switch things between my shit and their shit but share my wisdom anyway because I'm a greedy scumbag like that.
Where the shit really hit the fan is that I pointed out that PSR style guide doesn't answer all questions nor covers all cases so what do we do then. If it's not in PSR? Then we're fucked.4 -

Today my boss sent me something that smelled fishy to me. While he was trying to simulate Excel's rounding he faced what was to him unexpected behaviour and he claimed that one constructor of the BigDecimal class was "wrong".
It took me a moment why this was happening to him and I identified two issues in his code.
I found one fo the issues funny and I would like to present you a challenge. Can you find a number that disproves his claim?
It's Java if anyone was wondering.
double d = 102.15250;
BigDecimal db = new BigDecimal(d)
.setScale(3, BigDecimal.ROUND_HALF_EVEN);
BigDecimal db2 = new BigDecimal(String.format("%f",d))
.setScale(3, BigDecimal.ROUND_HALF_EVEN);
BigDecimal db3 = BigDecimal.valueOf(d)
.setScale(3, BigDecimal.ROUND_HALF_EVEN);
System.out.println(db); // WRONG! 102.153
System.out.println(db2); // RIGHT! 102.152
System.out.println(db3); // RIGHT! 102.152
P.s. of course the code itself is just a simple check, it's not how he usually writes code.
P.p.s. it's all about the numerical representation types.8 -
i'm starting a project where i will have a large amount audio clips, anywhere from a few seconds to about an hour long, and i need to store them based on which user created them and what group they are created in (so they will be sorted based on two integers). i'll need to concatenate and/or merge the audio files frequently, and i may need to filter which audio i use based on users and time created.
how should i store the audio? i'm pretty sure a database is the best option, but should i consider using the file system? if i shant, should i use mysql or postgres? i know postgres has more types and supports complex queries.
does anyone have experience who can help?8 -

Customer: So I have two emails and I'd like to be able to use them.
Me: Okay, I see you have both Windows Live Mail and Thunderbird...
Customer: Yeah, Thunderbird was the old one we used, we now use the Windows Live Mail, but it's always having problems.
Me: Well, Windows Live Mail isn't supported anymore, so I would recommend moving back to Thunderbird.
Customer: But that would mean I would have to get another email, right?
Me: No... *thinks for a moment* OK, imagine you have a garden hose that is connected to the main line of your house. You with me?
Customer: I guess...
Me: So the connection from your house is your email - or at least the server out on the internet. Now on the other end you have a hose splitter, and it splits off into two other hoses. Still with me?
Customer: Yeah...
Me: So on the end of the other two hoses you have two spray nozzles; one for each hose. Now one nozzle is from company A and the other is from company B. Both nozzles share some spray types on the heads, but there are a few heads on A that B doesn't have and vice versa.
Customer: OK...
Me: Those spray heads are Windows Live Mail and Thunderbird. They receive your mail from the same place, like the water, but they have different features. Does that makes sense?
Customer: I suppose.5 -

Developers more than other groups tend to hold their operating system or programming language of choice dearly, to the point where if someone thinks poorly of the OS or Language, they take it like a personal attack. Then there are those who think poorly of people who who's a certain OS or a specific language. Combine the two and you get hurt feelings and identity crisis.
Can we all just agree that we're all in different stages of learning and that we all generally end up going the same direction for the same types of problems?
Or just have it out and kill each other over it. Will give me great rant material.3 -
A Joke/Meme/Story. Sit down and enjoy
In my job we develop WebApps for any company that uses accounting stuff (like you must be wondering, all types of companies).
Some web developers may understand the problem with Internet Explorer and Bootstrap and some libraries 😂 and yes, we had a situaion where we had to put a message at the login to say that you must use Chrome or Firefox in order to use our system properly instead of Internet Explorer (unfortunately, too many factories in my city only use Internet Explorer)
The last week I had too much deadtime and I found this video (watch it from minute 0:55)
https://youtu.be/dfuMvkaDNfg
I laughed so hard 😂 it represents our situation with those Internet Explorer lovers 😂👊🏻
P.D. The video is in spanish, but don‘t worry. If you don‘t speak spanish, in few words, this video is about two roomies (alternative Bert and Ernie) and Bert is mad because Ernie installed Internet Explorer on Bert‘s laptop, so he ask him to uninstall it. Ernie uninstalled it, but he also erased disk C 😂6 -
Basically, there are two types of recruiters:
1. "Hi there. After reviewing your profile, I believe you have what it takes to be a <role> in our company."
2. "Hi there. After reviewing your profile, I'm convinced that you have what we need as a <role>."
Interestingly, the former tends to ignore your response if you rejected their advance, while the latter tends to follow up with a "just reach me out if you changed your mind", or even a simple "I understand, thank you for your time".1 -

tl;dr You can't just FUCKING RECOMPILE for an older OpenGL version you dimwit!
Context: Person Y has OpenGL 3.1, my program requires OpenGL 2.1, but refused to launch with "Pixel format not accelerated"

Person X - Today at 9:28 PM
Nope
or optionally compile it for old opengl
Or just use my old junk.
Me - Today at 9:29 PM
No
Person X - Today at 9:29 PM
Why?
Me - Today at 9:29 PM
You don't just "compile it for old opengl"
Person X - Today at 9:29 PM
I can
Btw
Me - Today at 9:29 PM
For one, Person Y has an OGL version new enough so... /shrug
Person X - Today at 9:29 PM
shrug
Me - Today at 9:30 PM
And there is no way I'm ripping the rendering code apart and re-doing everything with glBegin, glVertex, glEnd guff

This Rant is for all those toddlers like me who are exploring new places and platforms
I've worked on various platforms and interacted with various people everywhere. But believe me I've always categorised people in two : one who help and other who don't.
The one who don't help are indeed are of two types: one who know everything and want to pull you down
and
The other who know everything but guide you.
Most of us face the one who want to pull you down.
I'll suggest you to not get influenced by them.
They are everywhere, they might comment on my last post, they might -- my rant but still I love those who guide me.7 -
I hate coding tests for a job interview. I've done three types:
1) university style of "write function that does x" (fizz buzz)
2) this code has a bug, fix it
3) write a program that does this university style contrived thing (exact change)
One and two usually are timed to 10 to 15 minutes per question. Three is untimed but unstated "time counts".
Off all three, the last one is the best in my opinion. However it still seem like we could come up with something better.1 -
More from my big black book of ai and neuroscience:
I think if trace theory is true to any degree it would go some distance in explaining phenomenal consciousness, assuming I haven't misunderstood anything.
In fuzzy trace theory (FTT) it is posited that people form two types of mental representations about a past event:
*verbatim traces: detailed representations of a past event.
*gist traces: fuzzy representations of a past event.
People can reason with verbatim *and* gist traces but prefer gists.
*vision was suggested to work similarly in 1999. With human vision, two processes could be used: one that aggregates local receptive fields and one that parses the local receptive spatial field. It was suggested that people used prior experience, gists, to decide which dominates a perceptual decision.
Gist processes form representations of events, semantic details, where verbatim reinstates the context found in the surface details of an event.
__notes__
Parallel storage: asserts encoding/storage of verbatim/gist traces operate in *parallel*, not in serial.
I like to think of verbatim traces as databases, and gists as queries constructed by recognition.
Several studies have found that the meaning (gist) of an item is encoded even *before* the surface details (verbatim).
This might be important as a survival mechanism but should not be taken to mean strictly that gists are formed wholly *without* details or important and recognizable features of the item in question. It may well be for high level el processing and classification efficiency this may be an important reprocessing step, in the same way that many functions of the brain are duplicated throughout.5 -
[!dev], [toasters]
Does everyone only ever toast perfectly uniform slices of bread?
My grandma has a toaster that has two doors which open to the side and are held closed by a spring. This way if a slice is too thick the door can't close properly, but the damn thing still works. It's from before ww2, like most dead simple devices that work surprisingly well. I can't find anything similar anymore. The only two types now are the top-loaded design that simply doesn't work with thick slices, and the version for Americans or families of twelve that is the form factor of a smaller oven. (Which I obviously don't have room for. I already have an oven.)
Btw, how should I tag this? It's a rant, but it has nothing to do with the platform except perhaps the undocumented dependency between toasters and bread slicing machines.7 -
Currently implementing a Swift devRant SDK and encountered something very stupid:
The json value for attached image is an object (dictionary) when there is an image but it‘s an empty string "" when there is no image.
So two different types for the same property.

Why not make it null or omit that property when there is no image?
Now I need to add ugly as fuck custom decoding code for this object.25 -
I needed to align instruction execution to a 64bit boundary, for custom CPU architecture that I'm building. Basically the ISA had 3 types of instruction lengths; 16bit, 32bit, and 48bit. The core did 64bit fetch from the Instruction Cache, the issue was that if an instruction was in between two blocks of data I needed to fetch two blocks. That would impact performance a bit. So I had to modify GCC sources of the ISA that I'm using. So instead of doing it the right way, I just did it the lazy way and modified the GCC backend to print
.p2alignw 3, 0x00ff, 4
.p2alignw 3, 0x00ff, 2
On each 48bit and 32bit instruction to generate NOPs. And it did work lol. -
Aka... How NOT to design a build system.
I must say that the winning award in that category goes without any question to SBT.
SBT is like trying to use a claymore mine to put some nails in a wall. It most likely will work somehow, but the collateral damage is extensive.
If you ask what build tool would possibly do this... It was probably SBT. Rant applies in general, but my arch nemesis is definitely SBT.
Let's start with the simplest thing: The data format you use to store.
Well. Data format. So use sth that can represent data or settings. Do *not* use a programming language, as this can neither be parsed / modified without an foreign interface or using the programming language itself...
Which is painful as fuck for automatisation, scripting and thus CI/CD.
Most important regarding the data format - keep it simple and stupid, yet precise and clean. Do not try to e.g. implement complex types - pain without gain. Plain old objects / structs, arrays, primitive types, simple as that.
No (severely) nested types, no lazy evaluation, just keep it as simple as possible. Build tools are complex enough, no need to feed the nightmare.
Data formats *must* have btw a proper encoding, looking at you Mr. XML. It should be standardized, so no crazy mfucking shit eating dev gets the idea to use whatever encoding they like.
Workflows. You know, things like
- update dependency
- compile stuff
- test run
- ...
Keep. Them. Simple.
Especially regarding settings and multiprojects.
http://lihaoyi.com/post/...
If you want to know how to absolutely never ever do it.
Again - keep. it. simple.
Make stuff configurable, allow the CLI tool used for building to pass this configuration in / allow setting of env variables. As simple as that.
Allow project settings - e.g. like repositories - to be set globally vs project wide.
Not simple are those tools who have...
- more knobs than documentation
- more layers than a wedding cake
- inheritance / merging of settings :(
- CLI and ENV have different names.
- CLI and ENV use different quoting
...
Which brings me to the CLI.
If your build tool has no CLI, it sucks. It just sucks. No discussion. It sucks, hmkay?
If your build tool has a CLI, but...
- it uses undocumented exit codes
- requires absurd or non-quoting (e.g. cannot parse quoted string)
- has unconfigurable logging
- output doesn't allow parsing
- CLI cannot be used for automatisation
It sucks, too... Again, no discussion.
Last point: Plugins and versioning.
I love plugins. And versioning.
Plugins can be a good choice to extend stuff, to scratch some specific itches.
Plugins are NOT an excuse to say: hey, we don't integrate any features or offer plugins by ourselves, go implement your own plugins for that.
That's just absurd.
(precondition: feature makes sense, like e.g. listing dependencies, checking for updates, etc - stuff that most likely anyone wants)
Versioning. Well. Here goes number one award to Node with it's broken concept of just installing multiple versions for the fuck of it.
Another award goes to tools without a locking file.
Another award goes to tools who do not support version ranges.
Yet another award goes to tools who do not support private repositories / mirrors via global configuration - makes fun bombing public mirrors to check for new versions available and getting rate limited to death.
In case someone has read so far and wonders why this rant came to be...
I've implemented a sort of on premise bot for updating dependencies for multiple build tools.
Won't be open sourced, as it is company property - but let me tell ya... Pain and pain are two different things. That was beyond pain.
That was getting your skin peeled off while being set on fire pain.

There are two types of people who attempted to learn programming:
Those who are disappointed because they tried but failed to become a programmer
Those who became programmer for real but disappointed anyway7 -

My two main grudges against Typescript:
1) Union types can't be passed as arguments if there is a variant for every element of the union
2) No tuple polymorphism, i.e. [T, U] isn't assignable to [T]. This is not a mistake because the length of the arrays differs and therefore they may be interpreted in a different way, but IMO there should be a tuple type which is actually an array but length is unavailable and it supports polymorphism. This sounds stupid, but since function parameter lists work well with tuples it would actually enable a lot of functional tricks that are currently inaccessible.7 -
I've always was curious why people debating about mostly two code formatting types
for(;;)
{
//somestuff
}
or
for(;;){
//somestuff
}
while almost no one uses pretty decent IMO type like
for(;;){
//somestuff
//somemorestuff} (with tabs ofc)
It might be easier to forget some }s, but other than that it seems pretty nice to me13 -
I could really do with HKT support in Rust right now. I need to somehow convert a
Marc<Task<Output = T>> into a
Task<Output = Marc<T>> where Marc is a Mappable Atomic Reference Counter from the mappable_rc crate. Nothing technically challenging in the whole operation, it's just not supported by the type system without those two types knowing about each other. -
There's two types of developer.
Type 1 :
def function() {

Type 2 :

val true : bool = isFrustrated(me : Human)
1) Honestly fuck SML. Who's goddamn idea was it to make a useless fucking programming language that does absolutely nothing relevant unless you're trying to learn recursion. Who's fucking idea was it to not be able to even have side effects. And who gives a shit if you can explicitly declare the type of variables on every single fucking line that's what comments are for if you really need it. All this is aside from the fact that nobody ever has been like "OH UNMUTABLE TYPES? WOW IM SO HAPPY THIS IS SO USEFUL". At this point I feel like SML is basically a DFA - ABSOLUTELY FUCKING USELESS
2) Aside from that, who's idea was it to duplicate two classes. There's 15-122 (Principles of Imperative Computation) and 15-150 (Principles of Functional Programming). So far the ONLY fucking thing different is we learned about work and span in 15-150 - OTHER THAN THAT ITS LIKE TAKING THE EXACT SAME COURSE. BUT AGAIN. So then I have to fucking sit in lecture and pay attention for that tiny bit of information that is new amongst the giant cesspool of information that isn't. BECAUSE I ALREADY LEARNED IT.
Oh and did I mention that both classes are required to graduate as a CS major? Fuck me.
Thanks devRant for helping <3
Edit: We are 4 weeks into the semester so you'd expect we'd have gotten into the new stuff by now right????5 -
I'm beginning to feel like any kind of specific approximation via neural networks is a myth. That if you can't reduce output to simple categorical values that can be broadly interpreted between two points, that it doesn't work.
I have some questions and they don't seem to be getting answered about the design of the net. How many layers should I use ? How many neurons per layer ? How does this relate to the number of desired quantitive scalar outputs I'm looking to create, even if they are normalized, they can vary GREATLY and will if I'm approximating the out of several mathematical expressions. Based on this and the expected error ranges of these numbers and how many possible major digits could be produced within the domain of the variable inputs being introduced, how many neurons per layer ? What does having more layers do ? In pytorch there don't seem to be a lot of layer types per say, but there are a crap ton of activation functions, and should I just be using these at the tail end or should they actually be inserted between layers so the input of the next layer passes through another series of actiavtion functions ? what does this do to the range of output ?
do I need to be a mathematician to do this ?
remembered successes removed quantifiable scalars entirely from output, meaning that I could interpret successful results from ranges of decimal points.
but i've had no success with actual multi variable regression as of yet, even when those input variables are only 2 and on limited value ranges eg [0,100] and [0, 2pi]
and then there are training epochs to avoid overfitting, and reasonable expectation of batches till quality results will start to form.3 -
#Suphle Rant 6: Deptrac, phparkitect
This entry isn't necessarily a rant but a tale of victory. I'm no more as sad as I used to be. I don't work as hard as I used to, so lesser challenges to frustrate my life. On top of that, I'm not bitter about the pace of progress. I'm at a state of contentment regarding Suphle's release
An opportunity to gain publicity presented itself last month when cfp for a php event was announced last month. I submitted and reviewed a post introducing suphle to the community. In the post, I assured readers that I won't be changing anything soon ie the apis are cast in stone. Then php 7.4 officially "went out of circulation". It hit me that even though the code supports php 8 on paper, it's kind of a red herring that decorators don't use php 8 attributes. So I doubled down, suspending documentation.
The container won't support union and intersection types cuz I dislike the ambiguity. Enums can't be hydrated. So I refactored implementation and usages of decorators from interfaces to native attributes. Tried automating typing for all class properties but psalm is using docblocks instead of native typing. So I disabled it and am doing it by hand whenever something takes me to an unfixed class (difficulty: 1). But the good news is, we are php 8 compliant as anybody can ask for!
I decided to ride that wave and implement other things that have been bothering me:
1) 2 commands for automating project setup for collaborators and user facing developers (CHECK)
2) transferring some operations from runtime to compile/build TIME (CHECK)
3) re-attempt implementing container scopes
I tried automating Deptrac usage ie adding the newly created module to the list of regulated architectural layers but their config is in yaml, so I moved to phparkitect which uses php to set the rules. I still can't find a library for programmatically updating php filed/classes but this is more dynamic for me than yaml. I set out to implement their library, turns out the entire logic is dumped into the command class, so I can neither control it without the cli or automate tests to it. I take the command apart, connect it to suphle and run. Guess what, it detects class parents as violations to the rule. Wtflyingfuck?!
As if that's not bad enough, roadrunner (that old biatch!) server setup doesn't fail if an initialization script fails. If initialization script is moved to the application code itself, server setup crumbles and takes the your initialization stuff down with it. I ping the maintainer, rustacian (god bless his soul), who informs me point blank that what I'm trying to do is not possible. Fuck it. I have to write a wrapper command for sequentially starting the server (or not starting if initialization operations don't all succeed).
Legitimate case to reinvent the wheel. I restored my deleted decorators that did dependency sanitation for me at runtime. The remaining piece of the puzzle was a recursive film iterator to feed the decorators. I checked my file system reader for clues on how to implement one and boom! The one I'd written for two other features was compatible. All I had to do was refactor decorators into dependency rules, give them fancy interfaces for customising and filtering what classes each rule should actually evaluate. In a night's work (if you're discrediting how long writing the original sanitization decorators and directory iterator), I coupled the Deptrac/phparkitect library of my dreams. This is one of the those few times I feel like a supreme deity
Hope I can eat better and get some sleep. This meme is me after getting bounced by those three library rejections

ComPDFKit Solutions
For text extraction technology, ComPDFKit offers the following two solutions that effectively address text extraction for all types of PDF files. For documents containing only text information, our non-intelligent solution can suffice. But for more complex documents and image-based ones, ComPDFKit Document AI offers higher accuracy in text extraction. To learn about the accuracy of ComPDFKit's information extraction, see this article.
1. Algorithm: X-Y Cut Recursion Projection Method
The X-Y Cut Recursion Projection Method is a top-down page segmentation technique that decomposes a document image into rectangular blocks. It employs a recursive approach by projecting along both the X and Y axes to segment a PDF into independent rectangles, facilitating the extraction of textual components. ComPDFKit utilizes this method for efficient text separation and structural organization, including rows, paragraphs, and columns, to retrieve characters, words, lines, and paragraphs from the document.
The advantage of the X-Y Cut Recursion Projection Method is its speed, making it suitable for simple, structured, non-image-based PDF documents. However, for complex, unstructured PDFs, there might be recognition errors or omissions.
2. ComPDFKit Document AI
Document AI is an intelligent text extraction solution supporting all types of PDF files, including image-based. It uses artificial intelligence-based methods for document recognition and analysis to extract textual information from PDF documents (as well as images, tables, etc.).
- PDF Recognition and Analysis: This involves using deep learning models to recognize and analyze PDF documents, extracting elements like text, images, and tables while retaining their position, size, style, etc. ComPDFKit owns well-trained AI models to accomplish this process.
- Image Pre-processing: This process involves improving the quality and clarity of low-quality images in PDF documents, enhancing subsequent recognition and analysis. ComPDFKit employs multiple image processing techniques, such as image sharpening enhancement, noise reduction, document trimming and straightening, and stamp detection.
- OCR (Optical Character Recognition): OCR technology has a wide range of application scenarios such as license plate recognition, bank card information extraction, identity document (ID card) information recognition, train ticket information detection, etc. ComPDFKit supports recognition in dozens of languages. With extensively trained model zoo, it can accurately detect and recognize text in documents and analyze document structure.
