Yesterday: Senior dev messages out a screenshot of someone using an extension method I wrote (he didn’t know I wrote it)..
SeniorDev: “OMG…that has to be the stupidest thing I ever saw.”
Me: “Stupid? Why?”
SeniorDev: “Why are they having to check the value from the database to see if it’s DBNull and if it is, return null. The database value is already null. So stupid.”
Me: “DBNull is not null, it has a value. When you call the .ToString, it returns an empty string.”
SeniorDev: ”No it doesn’t, it returns null.”
<oh no he didn’t….the smack down begins>
Me: “Really? Are you sure?”
SeniorDev: “Yes! And if the developer bothered to write any unit tests, he would have known.”
Me: “Unit tests? Why do you assume there aren’t any unit tests? Did you look?”
<at this moment, couple other devs take off their head phones and turn around>
SeniorDev:”Well…uh…I just assumed there aren’t because this is an obvious use case. If there was a test, it would have failed.”
Me: “Well, let’s take a look..”
<open up the test project…navigate to the specific use case>
Me: “Yep, there it is. DBNull.Value.ToString does not return a Null value.”
SeniorDev: “Huh? Must be a new feature of C#. Anyway, if the developers wrote their code correctly, they wouldn’t have to use those extension methods. It’s a mess.”
<trying really hard not drop the F-Bomb or two>
Me: “Couple of years ago the DBAs changed the data access standard so any nullable values would always default to null. So no empty strings, zeros, negative values to indicate a non-value. Downside was now the developers couldn’t assume the value returned the expected data type. What they ended up writing was a lot of code to check the value if it was DBNull. Lots of variations of ‘if …’ , ternary operators, some creative lamda expressions, which led to unexpected behavior in the user interface. Developers blamed the DBAs, DBAs blamed the developers. Remember, Tom and DBA-Sam almost got into a fist fight over it.”
SeniorDev: “Oh…yea…but that’s a management problem, not a programming problem.”
Me: “Probably, but since the developers starting using the extension methods, bug tickets related to mis-matched data has nearly disappeared. When was the last time you saw DBA-Sam complain about the developers?”
SeniorDev: “I guess not for a while, but it’s still no excuse.”
Me: “Excuse? Excuse for what?”
<couple of awkward seconds of silence>
SeniorDev: “Hey, did you guys see the video of the guy punching the kangaroo? It’s hilarious…here, check this out.. ”

So I have complained to our landlord about a noisy neighbor who keeps blasting shitty music at midnight, and technically its against the law as well, but this bitch ass joke of a human being ignored even the most highest of authority.
Seeing I can't solve it with democracy, I finally gave up with any reasonable type of way to restrain this motherfucker (even calling police didn't help) and went full asshole with him
I know his WiFi uses WPS PIN, but I'm not gonna throttle his network, I want to piss him off so much he'll regret living beside me, or at our place entirely.
So I performed a Evil Twin attack, I had my Raspberry Pi act as a both cloned AP and a deauther. Finally the plan came to effect.
I ran the deauther in his AP, effectively disconnecting his devices, and had the devices connect to the cloned network. The primary aim of my attack is to annoy this bitch ass to the point of no return. The project I used serves a website on the cloned AP like a update for his router. I intentionally made it run overnight, blasted Lo-fi hip hop and went to sleep. Before I dozed off, I can hear their scream of rage because they can't blast their music at full volume (waddaya guess, they use Spotify).
I finally woke up the next day, and I find neighbor complaining about me, and they were trying to tell the landlord I was hacking them. It's technically true but its not as bad as domestic disturbance for a full fucking week.
Landlord asked me if I did it, I declined, she believed me (I know she does because she knows I'm a pure soul unlike this mofo). Then he left frustrated, threatened to sue me for hacking.
I just smickered, he can't really prove anything unless I was being sloppy.
Nowadays I get good sleep and finally we live in a quite peaceful place now. Now you may ask, what happened to that guy? After he threatened me, the next night he found his things outside his own room, he was kicked out by the landlord.
Moral of the story: we ain't hating on your music taste but don't showcase it like its the most important thing in the world when everyone is sleeping. Case and point, don't be an asshole18 -
Started being a Teaching Assistant for Intro to Programming at the uni I study at a while ago and, although it's not entirely my piece of cake, here are some "highlights":
* students were asked to use functions, so someone was ingenious (laughed my ass off for this one):
def all_lines(input):
all_lines =input
return all_lines
* "you need to use functions" part 2
*moves the whole code from main to a function*
* for Math-related coding assignments, someone was always reading the input as a string and parsing it, instead of reading it as numbers, and was incredibly surprised that he can do the latter "I always thought you can't read numbers! Technology has gone so far!"
* for an assignment requiring a class with 3 private variables, someone actually declared each variable needed as a vector and was handling all these 3 vectors as 3D matrices
* because the lecturer specified that the length of the program does not matter, as long as it does its job and is well-written, someone wrote a 100-lines program on one single line
* someone was spamming me with emails to tell me that the grade I gave them was unfair (on the reason that it was directly crashing when run), because it was running on their machine (they included pictures), but was not running on mine, because "my Python version was expired". They sent at least 20 emails in less than 2h
* "But if it works, why do I still have to make it look better and more understandable?"
* "can't we assume the input is always going to be correct? Who'd want to type in garbage?"
* *writes 10 if-statements that could be basically replaced by one for-loop*
"okay, here, you can use a for-loop"
*writes the for loop, includes all the if-statements from before, one for each of the 10 values the for-loop variable gets*
* this picture
N.B.: depending on how many others I remember, I may include them in the comments afterwards19 -
Python. Changed a function to return a tuple instead of one value in some database code. Tests pass, gets deployed, everything works. End of the month comes. Suddenly, we get a report that we're draining people's bank accounts and credit cards.
It turns out there was an untested bit of code inside the billing process that used this function. It used the function that was changed. To make matters worse, when the exception was thrown, the billing had already completed successfully, and due to another unrelated bug it would retry despite this.
So, needless to say, type safety and good unit tests are things I prioritize nowadays.7 -
USER: I can't see any data in the page...!
ME: ok, I'll do a check
ME: API calls get no data back. Boss, did you change anything and put it in production?
BOSS: Absolutely not, I just modified the name of what was the "Family" parameter in "Type".
ME: Seems legit. Totally agree. I'm going to lunch. Can you check in the meanwhile why calling the API with "Family" does return nothing? Thanks.3 -
It's maddening how few people working with the internet don't know anything about the protocols that make it work. Web work, especially, I spend far too much time explaining how status codes, methods, content-types etc work, how they're used and basic fundamental shit about how to do the job of someone building internet applications and consumable services.
The following has played out at more than one company:
App: "Hey api, I need some data"
API: "200 (plain text response message, content-type application/json, 'internal server error')"
App: *blows the fuck up
*msg service team*
Me: "Getting a 200 with a plaintext response containing an internal server exception"
Team: "Yeah, what's the problem?"
Me: "...200 means success, the message suggests 500. Either way, it should be one of the error codes. We use the status code to determine how the application processes the request. What do the logs say?"
Team: "Log says that the user wasn't signed in. Can you not read the response message and make a decision?"
Me: "That status for that is 401. And no, that would require us to know every message you have verbatim, in this case, it doesn't even deserialize and causes an exception because it's not actually json."
Team: "Why 401?"
Me: "It's the code for unauthorized. It tells us to redirect the user to the sign in experience"
Team: "We can't authorize until the user signs in"
Me: *angermatopoeia* "Just, trust me. If a user isn't logged in, return 401, if they don't have permissions you send 403"
Team: *googles SO* "Internet says we can use 500"
Me: "That's server error, it says something blew up with an unhandled exception on your end. You've already established it was an auth issue in the logs."
Team: "But there's an error, why doesn't that work?"
Me: "It's generic. It's like me messaging you and saying, "your service is broken". It doesn't give us any insight into what went wrong or *how* we should attempt to troubleshoot the error or where it occurred. You already know what's wrong, so just tell me with the status code."
Team: "But it's ok, right, 500? It's an error?"
Me: "It puts all the troubleshooting responsibility on your consumer to investigate the error at every level. A precise error code could potentially prevent us from bothering you at all."
Team: "How so?"
Me: "Send 401, we know that it's a login issue, 403, something is wrong with the request, 404 we're hitting an endpoint that doesn't exist, 503 we know that the service can't be reached for some reason, 504 means the service exists, but timed out at the gateway or service. In the worst case we're able to triage who needs to be involved to solve the issue, make sense?"
Team: "Oh, sounds cool, so how do we do that?"
Me: "That's down to your technology, your team will need to implement it. Most frameworks handle it out of the box for many cases."
Team: "Ah, ok. We'll send a 500, that sound easiest"
Me: *..l.. -__- ..l..* "Ok, let's get into the other 5 problems with this situation..."
Moral of the story: If this is you: learn the protocol you're utilizing, provide metadata, and stop treating your customers like shit.22 -
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.

I wrote a database migration to add a column to a table and populated that column upon record creation.
But the code is so freaking convoluted that it took me four days of clawing my eyes out to manage this.
BUT IT'S FINALLY DONE.
FREAKING YAY.
Why so long, you ask? Just how convoluted could this possibly be? Follow my lead ~
There's an API to create a gift. (Possibly more; I have no bloody clue.)
I needed the mobile dev contractor to tell me which APIs he uses because there are lots of unused ones, and no reasoning to their naming, nor comments telling me what they do.
This API takes the supplied gift params, cherry-picks a few bits of useful data out (by passing both hashes by reference to several methods), replaces a couple of them with lookups / class instances (more pass-by-reference nonsense). After all of this, it logs the resulting (and very different) mess, and happily declares it the original supplied params. Utterly useless for basically everything, and so very wrong.
It then uses this data to call GiftSale#create, which returns an instance of GiftSale (that's actually a Gift; more on that soon).
GiftSale inherits from Gift, and redefines three of its methods.
GiftSale#create performs a lot of validations / data massaging, some by reference, some not. It uses `super` to call Gift#create which actually maps to the constructor Gift#initialize.
Gift#initialize calls Gift#pre_init (passing the data by reference again), which does nothing and returns null. But remember: GiftSale inherits from Gift, meaning GiftSale#pre_init supersedes Gift#pre_init, so that one is called instead. GiftSale#pre_init returns a Stripe charge object upon success, or a Gift (and a log entry containing '500 Internal') upon failure. But this is irrelevant because the return value is never actually used. Pass by reference, remember? I didn't.
We're now back at Gift#initialize, Rails finally creates a Gift object using the args modified [mostly] in-place by all of the above.
Another step back and we're at GiftSale#create again. This method returns either the shiny new Gift object or an error string (???), and the API logic branches on its type. For further confusion: not all of the method's returns are explicit, and those implicit return values are nested three levels deep. (In Ruby, a method will return the last executed line's return value automatically, allowing e.g. `def add(a,b); a+b; end`)
So, to summarize: GiftSale#create jumps back and forth between Gift five times before finally creating a Gift instance, and each jump further modifies the supplied params in-place.
Also. There are no rescue/catch blocks, meaning any issue with any of the above results in a 500. (A real 500, not a fake 500 like last time. A real 500, with tragic consequences.)
If you're having trouble following the above... yep! That's why it took FOUR FREAKING DAYS! I had no tests, no documentation, no already-built way of testing the API, and no idea what data to send it. especially considering it requires data from Stripe. It also requires an active session token + user data, and I likewise had no login API tests, documentation, logging, no idea how to create a user ... fucking hell, it's a mess.)
Also, and quite confusingly:
There's a class for GiftSale, but there's no table for it.
Gift and GiftSale are completely interchangeable except for their #create methods.
So, why does GiftSale exist?
I have no bloody idea.
All it seems to do is make everything far more complicated than it needs to be.
Anyway. My total commit?
Six lines.
IN FOUR FUCKING DAYS!

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 -
FUCK PHP!!!
We were trying to go live with a big online shop, it is connected through a crappy API to SAP.
PHP keeps outputting fucking errors because our intern doesn't fucking know how to properly write PHP.
YEAH, JUST FUCKING RETURN A WHOLE DIFFERENT TYPE OF DATA IF THE FUNCTION HAS AN ERROR.
Oh and using fucking strtr( ... ) to insert stuff in a string is REALLY FUCKING 1337...
And when you think the whole fuckery has reached the summit, just look at how HE FUCKING CREATED THE UGLY EMAIL TEMPLATE:
$content .= "UGLY HTML ABOMINATION";
$content .= "MORE UGLY HTML";
$content .= "HTML WITH SPELLING ERRORS";
$content .= "<table>";
$content .= "TEARS OF TIM BERNERS LEE";
$content .= "<table>HE FOGOT THE FUCKING '/'";
and dozens more of these lines...
and the whole piece for ALL 3 FUCKING LANGUAGES...
Thanks for writing the fucking backend stuff, it is better to rewrite the whole piece.19 -
Am I the only one who, when working with dynamically typed languages, never uses dynamic features? Like, I never change a variable type, and make sure functions will only return one data type?
I just think dynamic types leads to so many bugs6 -
Dynamically typed languages are barbaric to me.
It's pretty much universally understood that programmers program with types in mind (if you have a method that takes a name, it's a string. You don't want a name that's an integer).
Even it you don't like the verbosity of type annotations, that's fine. It adds maybe seconds of time to type, which is neglible in my opinion, but it's a discussion to be had.
If that's the case, use Crystal. It's statically typed, and no type annotations are required (it looks nearly identical to Ruby).
So many errors are fixed by static typing and compilers. I know a person who migrated most of the Python std library to Haskell and found typing errors in it. *In their standard library*. If the developers of Python can't be trusted to avoid simple typing errors with all their unit tests, how can anyone?
Plus, even if unit testing universally guarded against typing errors, why would you prefer that? It takes far less time to add a type annotation (and even less time to write nothing in Crystal), and you get the benefit of knowing types at compile time.
I've had some super weird type experiences in Ruby. You can mock out the return of the type check to be what you want. I've been unit testing in Ruby before, tried mocking a method on a type, didn't work as I expected. Checked the type, it lines up.
Turns out, nested away in some obscure place was a factory that was generating types and masking them as different types because we figured "since it responds to all the same methods, it's practically the same type right?", but not in the unit test. Took 45 minutes on my time when it could've taken ~0 seconds in a statically typed language.11 -
Code review time:
Hey Rudy, can you approve my PR? ??? Shouldn't it be can you review my PR?(thought to myself)
Anyway, as a new practice, we(royal we) do not approve PRs with js files. If we touch one, we convert it to typescript as part of a ramp up to a migration that never seems to get here. But I digress.
I look at the laziest conversion in history.
Looked like
Import 'something';
Import 'somethingElse';
Import 'anotherSomething';
export class SomeClass {
public prop1: any;
public prop2: any;
public prop3: any;
public doWork(param: any){
let someValue = param;
// you get the idea
return someValue;
}
}
Anyway, I question if all the properties need to be visible outside of the class since everything was public.
Then if the dev could go and use type safety.
Then asked why not define the return type for the method since it would make it easier for others to consume.
Since parts of the app are still in js, I asked that they check that that the value passed in was valid(no compilation error, obviously).
Also to use = () => {} to make sure "this" is really this.
I also pointed out the import problem, but anyway.
I then see the his team leader approve the PR and then tell me that I'm being too hard on his devs. ????
Do we need to finish every PR comment with "pretty please" now?
These are grown men and women, and yet, it feels oddly like kindergarten.
I've written code in the past that wasn't pretty and I received "WTF?" as a PR comment. I then realized I ate sh*t on that line of code, corrected it and pushed the code. Then we went to Starbucks.
I'm not that old(35), but these young devs need to learn that COMPILERS DO NOT CARE ABOUT YOUR FEELINGS!!!!!
Ahhhhhh
Much better.
Thanks for the platform.8 -
Python Dev Learning C#: I'll just wait until I run the program to see what type the function returns.
Me: Static typing means you know that before the code even compiles!
Python Dev: Sometimes I forget that all functions explicitly say what they can return.4 -
TL;DR age != competence
My boss is a fucking computer illiterate self taught programmer.
Don't get me wrong, he can do shit, pretty shitty but it gets done...
But the dude has 38 fucking years old and somehow still searches for keys on the fucking keyboard and struggles to touch type anything...
I sometimes crying the fuck out when I have to help him with something...
I'm having a mini fucking panic attack right now just thinking of it... Fuck
He is our "manager" but doesn't even have the fucking balls to confront his own subordinates when they need to be confronted... Everyone is aware of this and everyone is fucking around... And no one sees any consequences... I wonder why deadlines are always missed...
He is so passive that every fucking thing someone asks he goes and says it is OK...
I was studying same psychology about ignorance and I think he lacks the understanding that shit is hard to do...
We literary had a conversation the other day something like that:
Boss: so, what do you think? One call to the api for it to return all data or multiple calls to return smaller ones?
Me: well... It takes ~180ms just for latency to the server for one call, if you have 10 calls it will take 180*10ms, it is better if we have one call and cache it if necessary on the backend.
( he has no fucking clue wtf caching is, besides browser cache)
Boss: (looking confuse AS FUCK!!) Well, I don't get it... Maybe I'll test it later.
Me thinking: test how you dumb motherfucker? On you fucking workstation with no fucking latency?
There is no fucking test. I'm stating it. IT IS A FUCKING FACT!
Me: well, it takes that for the call to go to the api and come back , its simple math. 1 == 180, 10 == 1800.
Suit yourself.7 -
Frustrated, tired and a bit lost.
I'm a "Senior PHP Backend Dev", which includes not the greatest tech stack nor the best job title, but it pays fine, and the company is awesome to work for.
I suck at writing features, but I'm great at bitching, and I easily put complex abstract concepts into usable models. So I'm also QA, tester, tech lead, database architect, whatever.
That makes writing PHP less annoying, because I create the rules, and whip devs around when they forget a return type definition or forget to handle an edge case. But I don't write a lot of code anymore, I mostly read (bad) code.
Lately I REALLY feel like doing something else... problem is that I know JS/ES6, but really dislike React/Vue and the whole crappy modern frontend toolchainchootrain of babelifyingwebpackingyarnballs. I know Python/Tensorflow/etc, but don't feel like I want to go into data science or AI. And then I'm awesome at the shit no one uses, like Haskell, Go and Rust (and worse).
I got a job offer which combines a very interesting PHP codebase with a Java infrastructure, where I could learn a lot... and I'm kind of tempted.
Problem is, everyone always shits on Java. I always made a bit of fun of Java myself. Don't even know exactly why, probably some really cruel instinct which causes kids to bully the least popular kid.
I know the basics, I've written the hello world, and a small backend app for a personal project. I know how strict and verbose it can be. I love the strictness in Haskell and Rust.... but those are both also quite terse.
Should I become a Java dev? I'm not talking about Android SDK, but an insane enterprise codebase at a life sciences corporation.
To the pro Java devs: What are the best and worst things about your job, about the weekly processes, about the toolchains? Have you ever considered other languages? Do you unconditionally love and believe in Java, or do you believe Swift, Kotlin, Scala or whatever will eventually make it completely obsolete?
Will Java hasten my decline into the cynical neckbeard I was always destined to be?
There are a lot more fun langauges, but looking at realistic demand and career value...20 -
While writing a raytracing engine for my university project (a fairly long and complex program in C++), there was a subtle bug that, under very specific conditions, the ray energy calculation would return 0 or NaN, and the corresponding pixel would be slightly dimmer than it should be.
Now you might think that this is a trifling problem, but when it happened to random pixels across the screen at random times it would manifest as noise, and as you might know, people who render stuff Absolutely. Hate. Noise. It wouldn't do. Not acceptable.
So I worked at that thing for three whole days and finally located the bug, a tiny gotcha-type thing in a numerical routine in one corner of the module that handled multiple importance sampling (basically, mixing different sampling strategies).
Frustrating, exhausting, and easily the most gruelling bug hunt I've ever done. Utterly worth it when I fixed it. And what's even better, I found and squashed two other bugs I hadn't even noticed, lol -
Creative dev compliments? Wow, that shows what type of person I am. I only know creative dev insults. Okay let me give it a go!
Wow, I'm gonna star that on GitHub!
Good work! I'm gonna put a shortcut to that right here on my desktop (in the same tone as "I'm gonna hang that on the fridge")

PHP arrays.
The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.
What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.
This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.
You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.
Bonus PHP trivia:
Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.
`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.
Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.
Strings can be indexed with negative integers. Arrays can't.
ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.
`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.5 -
If you are programming in C++ please always return a type from a function as the function prototype return type.
I had to debug some old code that failed to return a boolean on one of its flow paths. It would work on linux in release and debug, would work on windows in debug, and fail on windows in release.
The failure was NOT straightforward at ALL. It would return exit code 3. Then if I added a debug print to the function it would segfault.
Why the hell would popping something extra off the return/call stack not crash more readily? Wth is the point of debug compile if it won't catch shit like this?8 -
If you are teaching a newbie HTML and basic JS using ES6/ES2015 features, the "Hello World" app probably would be:

<input id='name'>
<button id='change-name'>Say Hello</button>
<h3 id='name-display'></h3>
</div>
<script type='module' src="./index.js"></script>
</body>
</html>
//index.js
import {sayHello} from './hello.js';
let displayArea = document.getElementById('name-display');
let input = document.getElementById('name');
let button = document.getElementById('change-name');
button.addEventListener('click', () => {
//displayArea.innerHTML = "Hello World"
displayArea.innerHTML = sayHello(input.value);
});
//hello.js
export const sayHello = (name='World') => {
return `Hello ${name}`;
};

So I'm doing some OpenGL stuff in C++, for debugging I've created a macro that basically injects my error check code after every OpenGL API call. Basically I don't want any of the code in release builds but I want it to be in debug. Also it needs to be usable inline and accept any GL function return type. From what I can tell I've satisfied all requirements by making the macro generate a generic lambda that returns the original function call result but also creates a stack object that uses the scope to force my error check after the return statement by using the destructor.
Basically I can do:
Log(gl(GetString(...));
gl(DeleteShader(...));
Etc where the GL call can be a function parameter or not.
So my question is, is the code shown in the picture the best way to achieve my goals while providing the behaviour im going for?13 -

TL;DR: Stop using React for EVERYTHING. It's not the end-all solution to every application need.
My team is staffed about 50/50 with tenured devs, and junior devs who have never written a full application and don't understand the specific benefits of different libraries/framworks. As a result, most of these junior devs have jumped on the React train, and they're under the impression that React is the end-all answer to any possible application need. Doesn't matter what type of app is, what kind of data is going to be flowing through the app, data scale, etc. In their eyes, React is always the answer. Now, while I'm not a big fan of React myself, I will say that it does its job when its tasked with a data-heavy application that needs to be refreshed/re-rendered dynamically and frequently (like Facebook.) However, my main gripe is that some people insist on using it for EVERYTHING. They refuse to acknowledge that there can be better library/framework choices (Angular, Vue, or even straight jQuery,) and they refuse to learn any other frameworks. You can hit them with countless technical reasons as to why React isn't a good choice for a particular application, and they'll just spout off the same tidbits from the "ReactJS Makes My Nips Hard 101" handbook: "React is the future," "Component-based web architecture is the future," (I'm not arguing with that last one) "But...JSX bro.," "Facebook and Netflix use it, so that's how you know it's amazing." They'll use React for a simple app, and make it overly-complex, and take months to write something that should have taken them a week. For example, we have one dev who has never used any other frameworks/libraries apart from React, and he used React (via create-react-app) to write what is effectively a single form and a content widget inside of a bootstrap template. It took him 4 MONTHS to write this, and it still isn't fully functioning. The search functionality doesn't really work (in fact, it's just array filtering,) and wont return any results if you search for the first word in an entry. His repo is a mess, filled with a bunch of useless files that were bootstrap'd in via create-react-app. We've built apps like this in a week in the past using different libraries/frameworks, and he could have done the same if he didn't overly-complicate the project by insisting on using React. If your app is essentially a dynamic form, you don’t need a freaking virtual DOM.
This happens every time a big new framework hits the scene. New young developers get sucked into it, because it's the cool hip new framework (or in React's case, library.) and they use it for everything, even when it's not the best choice. It happened with Angular, Rails, and now it's happening with React.
React has its benefits, but please please please consider which library/framework is the best choice from a technical standpoint before immediately jumping on the React train because "Facebook uses it bro."2 -
Look, I get that it's really tricky to assess whether someone is or isn't skilled going solely by their profile.
That's alright.
What isn't center of the cosmic rectum alright with the fucking buttsauce infested state of interviews is that you give me the most far fetched and convoluted nonsense to solve and then put me on a fucking timer.
And since there isn't a human being on the other side, I can't even ask for clarification nor walk them through my reasoning. No, eat shit you cunt juice swallowing mother fucker, anal annhilation on your whole family with a black cock stretching from Zimbabwe to Singapore, we don't care about this "reasoning" you speak of. Fuck that shit! We just hang out here, handing out tricks in the back alley and smoking opium with vietnamese prostitutes, up your fucking ass with reason.
Let me tell you something mister, I'm gonna shove a LITERAL TON of putrid gorilla SHIT down your whore mouth then cum all over your face and tits, let's see how you like THAT.
Cherry on top: by the time I began figuring out where my initial approach was wrong, it was too late. Get that? L'esprit d'escalier, bitch. I began to understand the problem AFTER the timer was up. I could solve it now, except it wouldn't do me any fucking good.
The problem? Locate the topmost 2x2 block inside a matrix whose values fall within a particular range. It's easy! But if you don't explain it properly, I have to sit down re-reading the description and think about what the actual fuck is this cancerous liquid queef that just got forcefully injected into my eyes.
But since I can't spend too much time trying to comperfukenhend this two dollar handjob of a task, which I'd rather swap for teabagging a hairy ass herpes testicle sack, there's rushing in to try and make sense of this shit as I type.
So I'm about 10 minutes down or so already, 35 to go. I finally decipher that I should get the XY coords of each element within the specified range, then we'll walk an array of those coordinates and check for adjacency. Easy! Done, and done.
Another 10 minutes down, all checks in place. TEST. Wait, wat? Where's the output? WHERE. THE FUCK. IS. THE OUTPUT?! BITCH GIMME AN ANSWER. I COUT'D THE RETURN AND CAN SEE THE TERMINAL BUT ITS NOT SHOWING ME ANYTHINGGG?! UUUGHHH FUCKKFKFKFKFKFKFKFUFUFUFFKFK (...)
Alright, we have about 20 minutes left to finish this motorsaw colonoscopy, and I can't see what my code is outputting so I'm walking through the code myself trying to figure out if this will work. Oh, look at that I have to MANUALLY click this fucking misaligned text that says "clear" in order for any new output to register. Lovely, 10/10 web design, I will violate your armpits with an octopus soaked in rabid bear piss.
Mmmh, looks like I got this wrong. Figures. I'm building the array of coordinates sequentially, as a one dimentional list, which is very inconvenient for finding adjacent elements. No problem, let's try and fix that aaaaaand... SHIT IM ALMOST OUT OF TIME.
QUICK LYEB, QUICK!! REMEMBER WHAT FISCELLA TAUGHT YOU, IN BETWEEN MOLESTING YOUR SOUL WITH 16-BIT I/O CONSOLE PROBLEMS, LIKE THAT BITCH SNOWFALL THING YOU HAD TO SOLVE FOR A FRIEND USING TURBO C ON A FUCKING TOASTER IN COMPUTER LAB! RUN MOTHERFUCKER RUN!!!
I'm SWEATING. HEAVILY. I'm STEAMING, NON-EROTICALLY. Less than 10 minutes left. I'm trying to correct the code I have, but I start making MORE dumbfuck mistakes because I'm in a hurry!
5 minutes left. As I hit this point of no return, I realize exactly where my initial reasoning went wrong, and how I could fix it, but I can't because I don't have enough time. Sadface.
So I hastily put together skeleton of the correct implementation, and as the clock is nearly up, I write a comment explaining the bits I can't get to write. Page up, top of file, type "the editor was shit LMAO" and comment it out. SUBMIT.

Spent 5+ years tolerating the bullshit of this guy (ex boss) and looks like it was a useless addition to my network.
I always got high praise from him and my colleagues and PMs. However, that never translated to good hikes/promotions/any favours of any type. Except for one time I never protested this because I saved the mental stress for other more important things (and that worked out well for me). It allowed me to sort of strut about the place like I own it and that was cool.
But today I needed to encash a favour from this reptile. And it was trivial enough that I thought I could count on that snake. But he did what he always does. Offered a useless alternative to any actual help.
So he helped, tried 'his best' according to 'policy', but I have to refuse it because it's like asking for water but getting air in return. Fucking chode.10 -
Let me tell you why I feel like a shit right now. I work as sw dev in a country worse than Germany and company I interviewed is located in Germany. So this is kinda big deal for me.
I interviewed with the company last year, interview went really well. They told me during interview that they would return in 2 weeks tops. It took 2 months for them tor return. For some reason, I was not hired for that position. Later I learned that the division i was gonna work defunded/separated. After learning that the guy I interviewed really tried hard to give me good news but failed-therefore had to delay bad news, I was not sad for not being able to be accepted for that position or delayed response.
Fast forward to this year, I interviewed with the same company for a position as subcontractor employee on another company. Interview took just before Coronavirus situation started to blow up(mid March), I had to return to my home country when the borders were closed asap, 2 day after interview. Fast forward to May I got the job offer and contract with a good salary, July as starting date. But I have no Visa and you apply for visa with a valid contract. German embassies work at minimum capacity, no new applications for any type of visa including work/residence visa. After my serious research I found a crack, emailed the embassy and they finally agreed to give me a special appointment on the start of July. The company I interviewed sent me new contract(August starting date) automatically.
On mid July, I told the company that visa might not come soon enough, I might not make it to August to start to job. We both agreed to replan starting date once i got the Visa.
On August 6, my visa came. I informed them asap, and they told me the other company will return in 3 weeks with new starting date. I was like WTF we were waiting for this visa for months, why do you need 3 weeks. Anyways, 3 weeks past and the other company still did not give any new starting date. I really feel like shit right now. Last week I asked to the "my" company if there is a problem with my employment(the other company might change plans after all) and they said only starting date is the problem, don't worry. On 3 occasions, they reassured me there was no problem(no, I was not asking them like paranoiac obsessive person, they were preemptively saying it in some cases). They say other company employees were really asking about when I was coming frequently.
What should one do in such situation. Do I even have legal rights? Maybe I will look back at this post and laugh at my paranoia, but I would you random internet citizens' ideas on this situation. They say lightning does not strike twice to same point but living same disappointment with the same company would really hurt. rant over, mamba out.8 -
short one.
So my CS course is full of people who can't write a fucking for loop (I shit you not) after more than half a year.
And then there's those that don't know what a return type is.
So I asked them once, after they stated that the course sucks, why they even chose it in the first place.
Freely translated it would be:
"I dunno, I thought we'd be doing cool hacker stuff in here..."
At that point I just wanted to jump out of the window.5 -
I am of the firm belief that a function should always return just one type.
I think it's the most convoluted thing that a function should be allowed to return any kind of type.
I've seen shit like return a string when something is valid and then a boolean if it's not valid.
To me, that kind of flexibility has some funky code smell.
I'm looking at you WordPress 🤨11 -
Ok now I'm gonna tell you about my "Databases 2" exam. This is gonna be long.
I'd like to know if DB designers actually have this workflow. I'm gonna "challenge" the reader, but I'm not playing smartass. The mistakes I point out here are MY mistakes.
So, in my uni there's this course, "Databases 2" ("Databases 1" is relational algebra and theoretical stuff), which consist in one exercise: design a SQL database.
We get the description of a system. Almost a two pages pdf. Of course it could be anything. Here I'm going to pretend the project is a YouTube clone (it's one of the practice exercises).
We start designing a ER diagram that describes the system. It must be fucking accurate: e.g. if we describe a "view" as a relationship between the entities User and Video, it MUST have at least another attribute, e.g. the datetime, even if the description doesn't say it. The official reason?
"The ER relationship describes a set of couples. You can not have two elements equal, thus if you don't put any attribute, it means that any user could watch a video only once. So you must put at least something else."
Do you get my point? In this phase we're not even talking about a "database", this is an analysis phase.
Then we describe the type dictionary. So far so good, we just have to specify the type of any attribute.
And now... Constraints.
Oh my god the constraints. We have to describe every fucking constraint of our system. In FIRST ORDER LOGIC. Every entity is a set, and Entity(e) means that an element e belongs to the set Entity. "A user must leave a feedback after he saw a video" becomes like
For all u,v,dv,df,f ( User(u) and Video(v) and View(u, v, dv) and feedback(u, v, f) ) ---> dv < df
provided that dv and df are the datetimes of the view and the feedback creation (it is clear in the exercise, here seems kinda cryptic)
Of course only some of the constraints are explicitly described. This one, for example, was not in the text. If you fail to mention any "hidden" constraint, you lose a lot of points. Same thing if you not describe it correctly.
Now it's time for use cases.
You start with the usual stickman diagram. So far so good.
Then you have to describe their main functions.
In first order logic. Yes.
So, if you got the point, you may think that the following is correct to get "the average amount of feedback values on a single video" (1 to 5, like the old YT).
(let's say that feedback is a relationship with attribute between User and Video
getAv(Video v): int
Let be F = { va | feedback(v, u, va) } for any User u
Let av = (sum forall f in F) / | F |
return av
But nope, there's an error here. Can you spot it (I didn't)?
F is a set. Sets do not have duplicates! So, the F set will lose some feedback values! I can not define that as a simple set!
It has to be a set of couples, like (v, u), where v is the value and u the user; this way we can have duplicate feedback values in our set.
This concludes the analysis phase. Now, the design.
Well we just refactor everything we have done until now. Is-a relations become relationships, many-to-many relationships get an "association entity" between them, nothing new.
We write down on paper every SQL statement to build any table, entity or not. We write down every possible primary key or foreign key. The constraint that are not natively satisfied by SQL and/or foreign keys become triggers, and so on.
This exam is considered the true nightmare at our department. I just love it.
Now my question is, do actually DB designers follow this workflow? Or is this just a bloody hard training in Pai Mei style?6 -
I created an account on here to shout my problems into the void.
At least I think that is the correct return type...8 -
Finally after wondering for hours why the constructor of a class does not get called...i notice that constructor don't fucking accept a return value data type (void)...😡😒8

in college ages ago, professor was "teaching" us overloading in C++, he goes something like this:
"so you can overload a function by changing the number of arguments, argument types, or method return type"
I dare put my hand up: "emm .. you can't overload by just changing the return type"
"you can"
"but, but.. how would the compiler know which overload I'm invoking when I call the method?"
pause..
"it depends on the type of the variable receiving the method call result"
"what if I call the method without assigning the result to a variable?"
agitated by now: "ah these are complex compiler concepts that are too complicated blah blah"
although I was unhappy, it was useful to realize no one knows everything5 -
So I spent the last 2 hours trying to figure out why my co-workers source when hitting the API I built was not working. They kept saying that the problem was the API and I kept saying that it's their implementation.
Turns out it was their implementation and as well as the API. Their implementation problem was not setting the "Accept" in the header. The API problem is how Laravel will return a JSON error response ONLY IF the "Accept" is set in the header.
I actually documented this into the API documentation but it's obvious that none of my co-workers read that you need to set the headers correctly. I think the more scary thing is that they didn't know the difference between Accept and Content-Type!!7 -

Working on an Android app for a client who has a dev team that is developing a web app in with ember js / rails. These folks are "in charge" of the endpoints our app needs to function. Now as a native developer, I'm not a hater of a web apps way of doing things but with this particular app their dev teams seems to think that all programming languages can parse json as dynamically as javascript...
Exhibit A:
- Sample Endpoint Documentation
* GetImportantInfo
* Params: $id // id of info to get details of
* Endpoint: get-info/$id
* Method: GET
* Entity Return {SampleInfoModel}
- Example API calls in desktop REST client
* get-info/1
- response
{
"a" : 0,
"b" : false,
"c" : null
}
* get-info/2
- response
{
"a" : [null, "random date stamp"],
"b" : 3.14,
"c" : {
"z" : false,
"y" : 0.5
}
}
* get-info/3
- response
{
"a" : "false" // yes as a string
"b" : "yellow"
"c" : 1.75
}
Look, I get that js and ruby have dynamic types and a string can become a float can become a Boolean can become a cat can become an anvil. But that mess is very difficult to parse and make sense of in a stack that relies on static types.
After writing a million switch statements with cases like "is Float" or "is String" from kotlin's Any type // alias for java.Object, I throw my hands in the air and tell my boss we need to get on the phone with these folks. He agrees and we schedules a day that their main developer can come to our shop to "show us the ropes".
So the day comes and this guy shows up with his mac book pro and skinny jeans. We begin showing him the different data types coming back and explain how its bad for performance and can lead to bugs in the future if the model structure changes between different call params. He matter of factually has an epiphany and exclaims "OHHHHHH! I got you covered dawg!" and begins click clacking on his laptop to make sense of it all. We decide not to disturb him any more so he can keep working.
3 hours goes by...
He burst out of our conference room shouting "I am the greatest coder in the world! There's no problem I can't solve! Test it now!"
Weary, we begin testing the endpoints in our REST clients....
His magic fix, every single response is a quoted string of json:
example:
- old response
{
"foo" : "bar"
}
- new "improved" response
"{ \"foo\" : \"bar\" }"
smh....8 -

Nice to do some refactoring of the whole data access layer of our core logistics software, let me tell an story.
The project is around 80k lines of code, with a lot of integrations with an ERP system and an sql database.
The ERP system is old, shitty api for it also, only static methods through an wrapper to an c++ library
imagine an order table.
To access an order, you would first need to open the database by calling Api.Open(...file paths) (yes, it's an fucking flat file type database)
Now the database is open, now you would open the orders table with method Api.Table(int tableId) and in return you would get an integer value, the pointer.
Now for the actual order. first you need to search for it by setting the search parameter to the column ID of the order number while checking all calls for some BS error code
Api.SetInt(int pointer, int column, int query Value)
Then call the find method.
Api.Find(int pointer)
Then to top this shitcake of an api of: if it doesn't find your shit it will use the "close enough" method of search.
And now to read a singe string 😑
First you will look in the outdated and incorrect documentation given to you from the devil himself and look for the column ID to find the length of the column.
Then you create a string variable with ALL FUCKING SPACES.
Now you call the Api.GetStr(int pointer, int column, ref string emptyString, int length)
Now you have passed your poor string to the api's demon orgy by reference.
Then some more BS error code checking.
Now you have read an string value 😀
Now keep in mind to repeat these steps for all 300+ columns in the order table.
News from the creators: SQL server? yes, sql is good so everything will be better?
Now imagine the poor developers that got tasked to convert this shitcake to use a MS SQL server, that they did.
Now I can honestly say that I found the best SQL server benchmark tool. This sucker creams out just above ~105K sql statements per second on peak and ~15K per second for 1.5 second to read an order. 1.5 second to read less than 4 fucking kilobytes!
Right at that moment I released that our software would grind to an fucking halt before even thinking about starting it. And that me & myself and I would be tasked to fix it.
4 months later and two weeks until functional beta, here I am. We created our own api with the SQL server 😀
And the outcome of all this...
Fixes bugs older than a year, Forces rewriting part of code base. Forces removal of dirty fixes. allows proper unit and integration testing and even database testing with snapshot feature.
The whole ERP system could be replaced with ~10 lines of code (provided same relational structure) on the application while adding it to our own API library.
Best part is probably the performance improvements 😀. Up to 4500 times faster and 60 times less memory usage also with only managed memory.3 -
Go home Dart, you're drunk

Our team (devs and QAs) have been doing a series of overtime work.
So, the company has provided us a place to sleep. Everyday, we would go to work at 10AM and then return to our place to rest at 12 midnight (sometimes at 2AM).
We've been doing this for a week now and we'll resume again tomorrow.
I already feel exhausted, and I was thinking of resigning after all of this mess was over.
However, I am having second thoughts. Since this is my first job, I have no point of comparison.
Perhaps a series of overtime like this one is normal? Is this type of work environment to be expected when being a developer? Or am I selling my self short and there are better options out there? What do you devs think?12 -
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 -
I'm a C++/Obj-C programmer finding it ludicrously hard to switch to Swift.
I find that the constant ability (leading to very poor programmer code) to reduce syntax and add tokens reduces readability and nowhere is this more apparent that with closures.
I'm working through (to my shame) Ray Wenderlich's Swift course and the closure chapter has this:
PS I loathe K&R as much as I do Swift so it's all in Allman formatting for clarity.
let multiply: (Int, Int) -> Int =
{
(a: Int, b: Int) -> Int in
// do Something else
return a * b
}
Why oh why isn't this more simply and elegantly written as:
let multiply = (a: Int, b: Int) -> Int
{
// do Something else
return a * b
}
The equals sign shows clearly that it's a closure definition assignment, as does the starting 'let'. But this way all of the stupid excesses, like the 'in' keyword, the repetition of the params / return type only this time with useful labels and additional tokens are removed and it looks and reads much more like a regular function and certainly a lot more clearly.
Now I know that with the stupid ability of Swift you can reduce all this down to return $0 * $1, but the point I'm making is that a) that's not as clear and more importantly b) if this closure does something more than just one line of code, then all that complicated stuff - hinted to by the comment '// do Something else' means you can't reduce it to stupid tokens.
So, when you have a clousure that has a lot of stuff going on and you can't reduce it to stupid minimalism, then why isn't is formatted and syntactically better like the suggestion above?
I've mentioned this on the Swift.org (and got banned for criticising Swift) but the suggestions they came up with were 'use type inference' to remove the first set of params / return type and token.
But that still means the param list and return type are NOT on the same line as the declaration and you still need the stupid 'in' keyword!5 -
I need some opinions on Rx and MVVM. Its being done in iOS, but I think its fairly general programming question.
The small team I joined is using Rx (I've never used it before) and I'm trying to learn and catch up to them. Looking at the code, I think there are thousands of lines of over-engineered code that could be done so much simpler. From a non Rx point of view, I think we are following some bad practises, from an Rx point of view the guys are saying this is what Rx needs to be. I'm trying to discuss this with them, but they are shooting me down saying I just don't know enough about Rx. Maybe thats true, maybe I just don't get it, but they aren't exactly explaining it, just telling me i'm wrong and they are right. I need another set of eyes on this to see if it is just me.
One of the main points is that there are many places where network errors shouldn't complete the observable (i.e. can't call onError), I understand this concept. I read a response from the RxSwift maintainers that said the way to handle this was to wrap your response type in a class with a generic type (e.g. Result<T>) that contained a property to denote a success or error and maybe an error message. This way errors (such as incorrect password) won't cause it to complete, everything goes through onNext and users can retry / go again, makes sense.
The guys are saying that this breaks Rx principals and MVVM. Instead we need separate observables for every type of response. So we have viewModels that contain:
- isSuccessObservable
- isErrorObservable
- isLoadingObservable
- isRefreshingObservable
- etc. (some have close to 10 different observables)
To me this is overkill to have so many streams all frequently only ever delivering 1 or none messages. I would have aimed for 1 observable, that returns an object holding properties for each of these things, and sending several messages. Is that not what streams are suppose to do? Then the local code can use filters as part of the subscriptions. The major benefit of having 1 is that it becomes easier to make it generic and abstract away, which brings us to point 2.
Currently, due to each viewModel having different numbers of observables and methods of different names (but effectively doing the same thing) the guys create a new custom protocol (equivalent of a java interface) for each viewModel with its N observables. The viewModel creates local variables of PublishSubject, BehavorSubject, Driver etc. Then it implements the procotol / interface and casts all the local's back as observables. e.g.
protocol CarViewModelType {
isSuccessObservable: Observable<Car>
isErrorObservable: Observable<String>
isLoadingObservable: Observable<Void>
}
class CarViewModel {
isSuccessSubject: PublishSubject<Car>
isErrorSubject: PublishSubject<String>
isLoadingSubject: PublishSubject<Void>
// other stuff
}
extension CarViewModel: CarViewModelType {
isSuccessObservable {
return isSuccessSubject.asObservable()
}
isErrorObservable {
return isSuccessSubject.asObservable()
}
isLoadingObservable {
return isSuccessSubject.asObservable()
}
}
This has to be created by hand, for every viewModel, of which there is one for every screen and there is 40+ screens. This same structure is copy / pasted into every viewModel. As mentioned above I would like to make this all generic. Have a generic protocol for all viewModels to define 1 Observable, 1 local variable of generic type and handle the cast back automatically. The method to trigger all the business logic could also have its name standardised ("load", "fetch", "processData" etc.). Maybe we could also figure out a few other bits too. This would remove a lot of code, as well as making the code more readable (less messy), and make unit testing much easier. While it could never do everything automatically we could test the basic responses of each viewModel and have at least some testing done by default and not have everything be very boilerplate-y and copy / paste nature.
The guys think that subscribing to isSuccess and / or isError is perfect Rx + MVVM. But for some reason subscribing to status.filter(success) or status.filter(!success) is a sin of unimaginable proportions. Also the idea of multiple buttons and events all "reacting" to the same method named e.g. "load", is bad Rx (why if they all need to do the same thing?)
My thoughts on this are:
- To me its indentical in meaning and architecture, one way is just significantly less code.
- Lets say I agree its not textbook, is it not worth bending the rules to reduce code.
- We are already breaking the rules of MVVM to introduce coordinators (which I hate, as they are adding even more unnecessary code), so why is breaking it to reduce code such a no no.
Any thoughts on the above? Am I way off the mark or is this classic Rx?16 -
ECMAScript is everywhere, so I thought: Let's do even more inappropriate and insane things with it ;)
...Like using Duktape (small ECMAScript engine) and exposing LoadLibrary/GetProcAddress along with some helper routines to describe the routine's argument types and return type, and finally providing a routine to invoke those routines.
It's a very rough prototype that can handle up to 4 arguments in a 64-bit Windows environment.
Next "todo" is structure handling which will initially be a case of stuffing data into a Buffer() object.
I'm not sure what exactly I'm trying to do with it or why...1 -
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 -
For a long time I was of the opinion that pointer variables in C/C++ should have the asterisk immediately after the type name (e.g. int* foo).
Eventually I became convinced that it makes more sense to have it before the variable (e.g. int *foo).
Now I find routines that return pointers look weird, e.g.: void *allocate_something() so I am considering adopting the original style I used.
The only advantage of having the asterisk before the variable name I am aware of is that it is easier to remember to add an asterisk if you define more than one pointer on that line.
Anyone else find it hard to settle on code style guidelines for their own personal projects?12 -
promises in JavaScript have really spoiled me
it's the most optimal way to do async without leaving much on the table
there's a promises library in rust and the guy who wrote it says it sucks because it spawns new thread every time you execute a bunch of promises
and I finally, through my fogged brain, managed to get the bright idea to write what I want to make in rust in JavaScript and holy hell it's sexy to work with promises. there's no performance left on the table. you do things as fast as possible
but if I take this JavaScript usability code I made and make it possible syntax-wise in rust I don't see how I would be able to do it without starting new operating system threads every time I execute any promises (or set)
I can take the overhead hit but this sounds retarded
and this isn't even touching upon how in rust everything needs to have a predetermined data type. so you can do lambdas and capture variables and send in variables into a thread that way, but to return the return object must be a consistent type (synchronizing the order data was sent in to the data sent out aside, haven't written that yet should be fine though)
which is fine if you are making a threadpool and it'll all be returning one data type
but this means you can't reuse a threadpool you made elsewhere in the program
the only thing that could fix async is to literally be compiler-enabled. it would have to work like generics and automatically make an enum of every type that can return, and only then could you re-use the threadpool23 -
DR-4798: Have notifications be marked as read only when clicked on instead of after seeing content
Priority: Should Fix
Type: Story
Description:
**Background**
Some users are reporting that they are not seeing all of their notifications because one notification marks all other notifications as read. This is because users mostly focus on the notification tapped on and then return to the notification screen. But other notifications such as mentions may reside on the same page and thus marks notification as read leaving users to miss out on possible important responses, etc.
Let’s change the way we mark notifications as read by only marking them as read once clicked on not seen.2 -
Once upon a time i had a great idea.
Because i couldnt be bothered to do anything productive i created a simple app in the C# that would look into every .js file (from a game that uses it for the gui/main menu) and search for "//todo" lines.
I did it mostly for kicks. I got that idea when i encountered one //todo in a file when i was trying to mod that game.
Yes i know grep exists: fuck you.
It would have taken me more time to learn that than to write that 20 line program...
The result? Over 30 lines of //todo with some briliant pearls in the type of:
>Temp workaround because X
>Workaround for race condition
>Clean that up
>Obsolete
When i return home i will post real quotes. They might be amusing to read...
The game is based on a custom C++ engine. HTML, CSS and JS is used for main menu and some graphical interface in game.
The most amusing thing is that this inefficient sack of chicken shit is powering one of the biggest (no playerbase but unit, world, gameplay vise) rts that i have ever played.
But still in spite of a dead community, buggy gui as shit and other problems i love this game and a lot of other people love it too. It is a great game when it works correctly.
To the interested: JS portion uses jquerry and knockout lib.14 -

Here’s a snippet of code that I found in our production codebase. I found this while fixing a bug. This is not part of the bug though but I see this a problem. Should I say this to my senior that his logic is off here?
First he doesnt have to do explicitly strict comparison since the return type is boolean and it could be true or false. Also the returnUrl will alway be undefined because redirectIfUserLoggedIn is called first before it was set.
He dosent like me. Hell get mad for sure. I think ill let this go.37 -
As opposed to my horrific experiences with PayPal, Swish, a Swedish (really smooth) payment processor has some really nice documentation. An example:
"The callback, in the happy case, will return an intermediate response with the status DEBITED."
And other nice things such as clear numbered lists describing user flows, with images for extra clarification. Also, they provide full lists of error responses and in many cases suggested way to proceed with these error cases.
And as the cherry on top, this is developed as a cooperation between a few Swedish banks. The banks, who are the most thick type of companies when it comes to IT, does it better than PayPal.6 -
bitter reflections from a bitter dev on hacktoberfest this year (in the past 2 hours of trying to find issues my IQ has at least halved):
- DefinitelyTyped - used to be my bread and butter to complete hacktoberfest; now, not sure if actual issue, or person just doesn't know how to use typescript (found a multiple such issues that were actually non-issues, the type they were asking for was right there, no pull request needed)
- avoid "issues" on no code / low code tools, these are toxic issues with titles like "I EXPLAIN BUG HERE", then probably not even a bug / more a feature request or clueless clown
- if your entire contributor team has the same character styled profile pic + background, i can't take you seriously; if your identity is so closely tied with what github team you are on... uh, i mean cmon what is this kindergarten? (also love the fact that an anon managed to get themselves mixed in hahahaha they ruined it perfectly!)
- most 'hacktoberfest' issue finders themselves are broken or don't load anything
- people claim issues and then never return YAWN
- the hacktoberfest discord: the projects channel is mostly people promoting their garbage repo WHICH HAS 0 OPEN ISSUES IN THE FIRST PLACE AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA and then OTHER people promoting their own portfolio on hacktoberfest???!! 😂😂😂😂 yeah bro i'm gonna help you with your own portfolio site GTFO
from what i've seen, i think i can start working approximately 5 minutes a day and be more successful than these absolute 🎪🤡🤹♂️ devs
sure, there is being a beginner, and there is being a clown salesmen trying to get people to do work for you... i mean wtf is going on
i WANT to help and contribute, but this year its really a struggle to find anything worthwhile to contribute to!
somehow the spark is gone... this might be my last Hacktoberfest... let me just return to my wisky and be in peace4 -
I have become the only thing I always hated in a developer. Building a project without a proper documentation.
As a solo developer in a company where I have to do database architecture, front-end, back-end, testing, NETWORKING (I am the most ignorant guy when it comes to networking), product design, there is no time for documentation.
But hey, I have structured the project, files and functions (with comment, parameters type and return type) properly and I understand what I've done even after 4-5 months without touching that specific project so I got that going for me which is nice... I guess.3 -
Generic arguments can't be cast. List<Dog> can't be cast to List<Animal>, because any methods that take Dog as an argument would suddenly have to work with an Animal (same works the other way round with return values).
But there are many situations where this would be okay. For instance, a Date can be cast to a String, so if we know that no method directly or indirectly accessible from a ListView<T> (including accessible property and field setters) will ever take an argument of type T, then ListView<Date> can be cast to a ListView<String>. Conversely, if we know that methods of StreamWriter will only ever take arguments of the generic type and interact in ways that don't change the object, then we can safely cast a StreamWriter<String> to a StreamWriter<Date>.
There could be a pair of generic constraints signifying that the type only crosses the interface boundary in one direction. I think this would be an interesting feature, but I don't know any strict type system that allows it. What do you think?25 -

Is it just me, or is form autofill in the browser just a major PITA for shop owners when people get to the checkout screen? I've had two clients in the past week with problems where users didn't pay attention to their autofill outcomes, or where the form absolutely has to keep a certain value that we've autofilled for them but gets overwritten by their browser. Now there is a shipment of product out in the wind that is going to return to sender and be delayed in a correction cycle. If you've been able to halt this type of nonsense, I'd love to know how you did it.

what the fuck are "covariant" return types...
I've been using java since java exists through all different versions. Mostly for web development.
Today I discovered "covariant" return type. What a shitty name.
I think I used the concept even without being aware of it...maybe just -oh- because Eclipse is allowing or even suggesting it.
I honestly cannot develop without Eclipse suggestions.
But here I am, survived 30 here in the business, developing end-to-end web applications for thousand of customers and deploying them.
And failing stupid questions in moronic interviews. Fuck.
PS also I don't use Streams. sorry.4 -
A bit longer rant, somehow triggered by the end of this rant:
https://devrant.com/rants/7145365/...
The discussion revolved around strpos returning false or a positive integer.
Instead of an Option or a Exception.
I said I'm a sucker for exception, but I'm also a sucker for typing.
Which is something most languages lack - except the lower level ones like C / C++.
I always loved languages which have unsigned and signed types.
There, I said it... :) I know that signed / unsigned is controversial, Google immediately leads to blog entries screaming bloody murder because unsigned can overflow – or underflow, if someone tries to use a -1on an unsigned integer.
Note that my love is only meant for numeric types, unsigned / signed char is ... a whole can of insanity on its own.
https://phoronix.com/news/...
If you wanna know more.
Back to the strpos problem, now with my secret love exposed:
strpos works on a single string, where a string is a sequence of chars starting with 0.
0 is a positive integer.
In case the needle (char that should be looked up in the string) cannot be found in the haystack (the string), PHP returns "false".
This leads to the necessity of explicitly checking the type as "0" (beginning of string, a string position)... So strpos !== false.
PHP interprets 0 as false, any other integer value is true.
In the discussion, the suggestion came up to return -1 if a value could not be found – which some languages do, for example Scala.
Now I said I have a love for unsigned & signed integers vs. just signed integers...
Can you guess why the -1 bothers me very much?
Because it's a value that's illogical.
A search in a sequence that is indexed by 0 can only have 0 or more elements, not less than zero elements.
-1 refers to a position in the sequence that *cannot* exist.
Which is - of course - the reason -1 was chosen as a return value for false, but it still annoys me.
An unsigned integer with an exception would be my love as a return value, mostly because an unsigned integer represents the return value *best*. After all, the sequence can only return a value of 0 ... X.
*sigh*
Yes, I know I'm weird.
I'm also missing unsigned in Postgres, which was more or less not implemented because it's not in the SQL standard...
*sob*29 -
Some compilers give an error message on forgotten type casting. From that it shows good typing style casting. So you also avoid clerical errors that can lead to the program crash in the worst case. With some types it is also necessary to perform type casting comma on others Types, however, do this automatically for the compiler.
In short:Type casting is used to prevent mistakes.
An example of such an error would be:
#include <stdio.h>
#include <stdlib.h>
int main ()
{
int * ptr = malloc (10*sizeof (int))+1;
free(ptr-1);
return 0;
}
By default, one tries to access the second element of the requested memory. However, this is not possible, since pointer calculation (+,-) does not work for a void pointer.
The improved example would be:
int * ptr = ((int *) malloc (10*sizeof (int)))+1;
Here, typecasting is done beforehand and this turns the void pointer into its int pointer and pointer calculation can be applied. Note: If instead of error "no output" is displayed on the sololearn C compiler try another compiler.1 -
We had made an api which had endpoints for each different domain model, so /user, /company, the usual. Beyond being restful they all had basic filtering and pagination.
We also had an endpoint to return an entity from any set based on guid for when you needed to attach the related entity to notifications and logging and such.
We received a bug report on how you couldn't use filtering or pagination on this endpoint, and after weeks of asking what they need it for we just had to implement it.
You can imagine how non-trivial it is to "just" filter across different datasets, but we eventually got it working so now you can get a user via /user/123 or /entity?type=user&id=123. They only use it for one type and id at the time.2 -
After 2 days of debugging why, oh why, GridView isn't displaying the content generated via function, I came to realize I forgot to type a "return" so the widget is actually returned.

FUUUCK TYPESCRIPT
It can't handle this function: `(arg) => arg` without kicking around a bunch of generics.
https://stackoverflow.com/questions...
This is ridiculous. The generics system on Typescript is complete trash, the amount of things it's unable to handle are unbelievable, and I feel like I'm taking crazy pills when I'm supposed to just accept that they couldn't possibly have done better.
Seriously, if I was one of the developers and I saw an issue like this, I wouldn't defend it; I'd be embarrassed.7 -
This story happened to everyone, and i am sure that if i search, i will find dozens of similar stories, but the different here is, i tried, i really tried, in a hundred different ways to achieve my goal !
When you are stuck on a problem, let's say, that you have a program, project, website ... and need to achieve something technically weird (or hard) and need some help to save you time on experimentations. The first thing a lot of people do is : Google.com && put search dorks.
But, at a moment, google gets "dirty", you use it so often that he always think to know better then you what you are looking for.
It reminds of "Ted", the movie (for thows who know it) where they asked : "Hey ! Why does google always suggest us to look for black dicks ??"
It is exactly what happened to me, i got results who doesn't have anything to do with what i was looking for !
You can give it a try now : type "semantic web RDF to RDB"
You won't find anything, except results related to : NOSQL DBs, which is totally annoying.
Something else, i once google swift to get some updates, what results did i got ? Taylor Swift ... (musician)
I often get 2 or 3 results from google, which made me thinking that i somewhat reached the end of internet, or that people are so dumb that i will have spend hours trying to figure my solutions, but, before doing that, other solutions had to be tested.
1- TOR : Google tracks his users and uses its algos and bullshits to return results as close as possible to the user's demand (big fail ...) so how about moving to a different country ? DL TOR browser, open, setup, go to US, open google (got us version YAY !) enter my keywords, and, nothing, still nothing, more results for sure, but nothing related to what i was looking for.
2- VM
Pop a VM, launch TOR, use Hidden mode, delet all cookies and stuff (it is a new VM but who knows).
Use keywords (now in UK). Here they are !! my results !!! i finally found some decent results about my keywords !
But, i have the required knowledge to do this kind of stuff, but how about people who rely heavily on google ? they can't change country, clear everything, trick google to think you are a new user, they have almost biased and flawed results. I tried duckduckgo (i love them) but they are not that efficient.
Google says not to anything evil, but they ARE EVIL, miss guiding people, suggesting corrections who have nothing to do with the keywords, or results totally unrelated in any way to the keywords while results exist in other countries ???
Ever since, i don't pay attention to google at all, and started thinking that google's algos are manipulating people, i don't know if it is done on purpose or not, but the result is the same, people have biased results based on their country, on their tag, on their ID, and the recent keywords.
During that period i was cursing google every funcking day, and i am still doing it, too much trackers, too much manipulation, i will end-up enclosing myself in darknet.4 -
My first programming lan was Lua. And they who know that lan knows, that I may was confused when I switched to a 'normal' programming lan like c# or java, because when you init a string you just type: a = ":)". but you can still set it to an int: a = 10. So every vars in Lua aren't sticked to a type. The arrays also can have any kind of var in it.
So I never learned what a String, int, ... is. I didn't understood why a method can't just return anything or why an array has a length.1 -
Using a library that is a wrapper around an API, seems to work fine and I can connect to the api with my credentials.
Cue me, a responsible dev, wanting to use Dependency Inversion using the library's interfaces so that I can mock them easily in tests.
var test lib.IObjectManager = lib.ObjectManager{}
Error: Return type of method 'GetA' is A and should be 'B' according to the interface!
Error: Return type of method 'GetE' is *E and should be 'E' according to the interface!
Clearly nobody ever tried to use that interface :/ -
Just spent 3 hours on a bs problem
I just start acceptance testing a node.js api.
I'm using frisby
I have logged the export method return data and it is correct
I am loading it into the set header function as the accept-type
On frisby side I run the test and it spits out that there is no accept-type
I really don't get why anymore. Came so close to a blind fury. -
The crazy shenanigans you can do with C++ standard libs are fascinating.
Like implementig multithreading with just a foreach, and bindings which can make member function pointers to simple function pointers, and placeholders in bindings. Also lambda functions are cool.
Something between the lines:
my_crazy_class *tmp = new my_crazy_class(...);
std::vector<type> my_array = .....;
std::for_each(std::execution::par,my_array.begin(),my_array.end(),
[&](type in){
auto fn = std::bind( &my_crazy_class::my_crazy_fnc,*tmp,_1,random_static_value);
return fn(in);
});
ps:
It's pretty much pseudocode, and please don't do things like this, it's bad for your mental health.
pps:
I need to learn how to use this tools wisely. -
I'm facing something strange, I have set the following headers in Nginx to return:
strict-transport-security: max-age=31536000; includeSubDomains
vary: Accept-Encoding
x-content-type-options: nosniff
X-Firefox-Spdy: h2
x-frame-options: SAMEORIGIN
x-xss-protection: 1
But I only get them when I browse root of my website, but if I go to https://website.com/subPage
those headers are not returned, now I did set them only on
"location / {}"
Any other headers I am missing that needs to be set?
in nginx, but how do I force it on all sub pages, or there is no need?2 -
Sweet Zombie NullFuckingPointerException...
New Rule: When creating an API (I'm looking at you, Java), designers must include a boolean flag in the parameter list of any method which throws a NullPointerException.
If TRUE, this means that a NULL result is non-trivial and the method should therefore THROW an NPE.
If set to FALSE, this means that NULL is completely f*cking trivial so whenever there's a NULL result, just instantiate a new instance of the return type and return that, 'cause that's what was gonna happen in the catch block of the NPE anyways.2 -
Top 12 C# Programming Tips & Tricks
Programming can be described as the process which leads a computing problem from its original formulation, to an executable computer program. This process involves activities such as developing understanding, analysis, generating algorithms, verification of essentials of algorithms - including their accuracy and resources utilization - and coding of algorithms in the proposed programming language. The source code can be written in one or more programming languages. The purpose of programming is to find a series of instructions that can automate solving of specific problems, or performing a particular task. Programming needs competence in various subjects including formal logic, understanding the application, and specialized algorithms.
1. Write Unit Test for Non-Public Methods
Many developers do not write unit test methods for non-public assemblies. This is because they are invisible to the test project. C# enables one to enhance visibility between the assembly internals and other assemblies. The trick is to include //Make the internals visible to the test assembly [assembly: InternalsVisibleTo("MyTestAssembly")] in the AssemblyInfo.cs file.
2. Tuples
Many developers build a POCO class in order to return multiple values from a method. Tuples are initiated in .NET Framework 4.0.
3. Do not bother with Temporary Collections, Use Yield instead
A temporary list that holds salvaged and returned items may be created when developers want to pick items from a collection.
In order to prevent the temporary collection from being used, developers can use yield. Yield gives out results according to the result set enumeration.
Developers also have the option of using LINQ.
4. Making a retirement announcement
Developers who own re-distributable components and probably want to detract a method in the near future, can embellish it with the outdated feature to connect it with the clients
[Obsolete("This method will be deprecated soon. You could use XYZ alternatively.")]
Upon compilation, a client gets a warning upon with the message. To fail a client build that is using the detracted method, pass the additional Boolean parameter as True.
[Obsolete("This method is deprecated. You could use XYZ alternatively.", true)]
5. Deferred Execution While Writing LINQ Queries
When a LINQ query is written in .NET, it can only perform the query when the LINQ result is approached. The occurrence of LINQ is known as deferred execution. Developers should understand that in every result set approach, the query gets executed over and over. In order to prevent a repetition of the execution, change the LINQ result to List after execution. Below is an example
public void MyComponentLegacyMethod(List<int> masterCollection)
6. Explicit keyword conversions for business entities
Utilize the explicit keyword to describe the alteration of one business entity to another. The alteration method is conjured once the alteration is applied in code
7. Absorbing the Exact Stack Trace
In the catch block of a C# program, if an exception is thrown as shown below and probably a fault has occurred in the method ConnectDatabase, the thrown exception stack trace only indicates the fault has happened in the method RunDataOperation
8. Enum Flags Attribute
Using flags attribute to decorate the enum in C# enables it as bit fields. This enables developers to collect the enum values. One can use the following C# code.
he output for this code will be “BlackMamba, CottonMouth, Wiper”. When the flags attribute is removed, the output will remain 14.
9. Implementing the Base Type for a Generic Type
When developers want to enforce the generic type provided in a generic class such that it will be able to inherit from a particular interface
10. Using Property as IEnumerable doesn’t make it Read-only
When an IEnumerable property gets exposed in a created class
This code modifies the list and gives it a new name. In order to avoid this, add AsReadOnly as opposed to AsEnumerable.
11. Data Type Conversion
More often than not, developers have to alter data types for different reasons. For example, converting a set value decimal variable to an int or Integer
Source: https://freelancer.com/community/...2 -
Just askin:
If you have a method which returns a value from an array. What do you prefer in a case when the item is not found?
A)Throw an exception
B)return null
C)return a special value like a null object or some primitive type edge value like Integer.MIN_VALUE14 -
Rust's Fn traits feel weird. The argument tuple is a generic parameter, but the return type is an associated type, even though Rust is supposed to use Hindley-Milner type inference, so inferring through return type should always fail if this were a regular trait.
Then, this would mean that blanket implementations for Fn(T) and Fn(T, U) should conflict because AnyTrait<(T)> and AnyTrait<(T, U)> aren't mutually exclusive. I tried, they work just fine.
There's some weird and I suspect unnecessary special case magic here, and I'd like to uncover it.17 -

C++ / OOP QUESTION
I have a uni assignment / project (Data Structures class), where I have to implement the ins-n-outs of 1D arrays, by creating a dynamically allocated array class, which can accept any type of data (using templates). But there's a problem.
I'd like to implement sorting the elements of the array. But given the fact, that I'm using templates, I cannot treat the elements as integers, nor as strings, or other types...
Also, let's say that the elements of the array are elements of class T, where T looks like this:
class T {
private:
double height;
int age;
string name;
public:
double getH() { return height; }
int getAge() { return age; }
string getName() { return name; }
};
(It's just a random example, pls don't judge for code quality...)
Let's say that I'd like to sort the T elements based on height, print out, sort by age, print out, then sort by name and print out. How can I do this? Is this possible?5 -
So I was writing SaltStack state for syslog management and I had a simple config file in place to be deployed on a test server. I was writing the command to run the state for the test server, and the only thing that was left was to type the hostname of the server (instead of wildcard) when someone interrupted me. After I got back to this terminal I instinctively pressed return sending test configuration to over 80 production servers. Nice one...

Warning: Might contain (be) stupid rambling.
So I got my new toy and want to play around with it. Just in case I have to return it I first want to make a full disk backup, so I try to boot clonezilla. I press the power button and mash F2, F8, F9 - and it boots straight into the windows setup. Nope, not what I wanted. Try again. And again. Eventually I look it up and apparently I have to hammer the ESC key to get where I want to. Alright, now it works. Boot from USB. Failed. Try again. Failed. Check the BIOS, disable secure boot, reboot. I need to type 4 digits to confirm disabling secure boot. Alright. Reboot, try again, failed. Secure boot is on again. Wtf? After some more infuriating tries I see that NumLock is disabled. AAAARGH. BIOS: Enable NumLock on boot, disable secure boot, enable legacy boot. Input the 4 digits - works! Try to boot from USB: Failed! Grab another USB stick, did the clonezilla image, try again: Finally! It! Works!

java.util.Optional.or, orElse and orElseGet should really have their signatures changed so they can widen the type. For example, `Optional<T> or(Supplier<? extends Optional<? extends T>> supplier)` should really be `<U, S super T & U> Optional<S> or(Supplier<? extends Optional<? extends U>> supplier)`
Then we could eliminate the following unchecked cast:
```
public static double getOrNan(Optional<? extends Number> optionalNumber) {
return ((Optional<Number>)optional).getOrElse(Double.NaN).doubleValue();
}

We have an internal nuget package that wraps up the IConfiguration+ConfigurationBuilder for various .net core console/service apps (TL;DR, because people got creative), and it has a dictionary property for the common sections we use. AppSettings (for backward compatibility), ConnectionStrings, and ServiceEndpoints. If the need arises, I can add methods to return any type of object (no one has requested yet, we try to keep configs dead simple)
ex. var myDatabaseConnectionString = ConfigurationManager.ConnectionStrings["MyDatabase"];
Code review for someone who updated a .net framework app to .net core and they wrote their own IConfiguration wrapper for accessing the appsettings.json file, so I pointed out that we already had a library for that.
In the reply, he said he couldn't use our library because it had an 'AppSettings' property and since his appsettings.json file didn't have that section, he didn't want to cause a runtime exception.
OK, WTF...I even sent him a link to the documentation (includes explaining the backward compatibility part)...why the frack would you think because a property exists and you don't use it, that would cause some kind of runtime exception?
We have dozens of .net framework apps migrated to .net core with zero code changes and no one ever brought this up as a concern (because, why would they?)
Deep breath...ahhh...I respond that not having an AppSettings section in the appsettings.json file won't cause an exception, if you don't have one, don't need it, you don't have to use it.
He went ahead merged+committed his code anyway with his own IConfiguration+ConfigurationBuilder plumbing.

Recently had trouble with some SQL. My tests would not pass, so I had to manually run it to debug it.
SELECT * FROM a JOIN b ON [...] WHERE b.foo NOTNULL
Yielded 0 of 3 rows. Expected 1
Tried querying WHERE b.foo ISNULL instead. Would have expected 2 of 3 rows, but got 1.
After googling i discovered that comparing with NULL does not return a true/false binary description, but may also return unknown if the type is not a NULL type, e.g. 42 ISNULL =" UNKNOWN

🐟💩The image i fetch from s3 is of type byte array
I return it to angular as an ArrayBuffer
Which then needs to be somehow converted to an image so i can fucking show it
Then after research i had to convert ArrayBuffer to Blob
And from Blob to URL encoded object which returns a string that now shows the full image in img tag
Somehow, by a sheer of trials and error i have just accidentally made a very secure way of fetching a very sensitive piece of document (verification document with user's personal data on it) and now in browser this is shown as blob:shit-image/random-hash. Not even the file extension. This means nobody can download this image. You fucking cant. Its a Blob motherfucker! Like a Blob Fish. It saves either a .txt when you try to save it (no idea how) and if you try to open the image in new tab it shows gibberish text. This means you can read-only this highly sensitive document image and not manipulate it, not even download it. Perfect. I have just made a very secure software by accident.

Sveltekit progressive enhancement form docs fucking suck.
Arbitrary, non-reproducible examples.
The docs show: return fail(400, { email, missing: true });
The client response says: {
"type": "success",
"status": 204

Man, if the docs were monkey-typewritten, they could have warned us first…
