Its Friday, you all know what that means! ... Its results day for practiseSafeHex's most incompetent co-worker!!!
*audience: wwwwwwooooooooo!!!!*
We've had a bewildering array of candidates, lets remind ourselves:
- a psychopath that genuinely scared me a little
- a CEO I would take pleasure seeing in pain
- a pothead who mistook me for his drug dealer
- an unbelievable idiot
- an arrogant idiot obsessed with strings
Tough competition, but there can be only one ... *drum roll* ... the winner is ... none of them!
*audience: GASP!*
*audience member: what?*
*audience member: no way!*
*audience member: your fucking kidding me!*
Sir calm down! this is a day time show, no need for that ... let me explain, there is a winner ... but we've kept him till last and for a good reason
*audience: ooooohhhhh*
You see our final contestant and ultimate winner of this series is our good old friend "C", taking the letters of each of our previous contestants, that spells TRAGIC which is the only word to explain C.
*audience: laughs*
Oh I assure you its no laughing matter. C was with us for 6 whole months ... 6 excruciatingly painful months.
Backstory:
We needed someone with frontend, backend and experience with IoT devices, or raspberry PI's. We didn't think we'd get it all, but in walked an interviewee with web development experience, a tiny bit of Angular and his masters project was building a robot device that would change LED's depending on your facial expressions. PERFECT!!!
... oh to have a time machine
Working with C:
- He never actually did the tutorials I first set him on for Node.js and Angular 2+ because they were "too boring". I didn't find this out until some time later.
- The first project I had him work on was a small dashboard and backend, but he decided to use Angular 1 and a different database than what we were using because "for me, these are easier".
- He called that project done without testing / deploying it in the cloud, despite that being part of the ticket, because he didn't know how. Rather than tell or ask anyone ... he just didn't do it and moved on.
- As part of his first tech review I had to explain to him why he should be using if / else, rather than just if's.
- Despite his past experience building server applications and dashboards (4 years!), he never heard of a websocket, and it took a considerable amount of time to explain.
- When he used a node module to open a server socket, he sat staring at me like a deer caught in headlights completely unaware of how to use / test it was working. I again had to explain it and ultimately test it for him with a command line client.
- He didn't understand the need to leave logging inside an application to report errors. Because he used to ... I shit you not ... drive to his customers, plug into their server and debug their application using a debugger.
... props for using a debugger, but fuck me.
- Once, after an entire 2 days of tapping me on the shoulder every 15 mins for questions / issues, I had to stop and ask:
Me: "Have you googled it?"
C: "... eh, no"
Me: "can I ask why?"
C: "well, for me, I only google for something I don't know"
Me: "... well do you know what this error message means?"
C: "ah good point, i'll try this time"
... maybe he was A's stoner buddy?
- He burned through our free cloud usage allowance for a month, after 1 day, meaning he couldn't test anything else under his account. He left an application running, broadcasting a lot of data. Turns out the on / off button on the dashboard only worked for "on". He had been killing his terminal locally and didn't know how to "ctrl + c a cloud app" ... so left it running. His intention was to restart the app every time you are done using it ... but forgot.
- His issue with the previous one ... not any of his countless mistakes, not the lack of even trying to make the button work, no, no, not for C. C's issue is the cloud is "shit" for giving us such little allowances. (for the record in a month I had never used more than 5%).
- I had to explain environment variables and why they are necessary for passwords and tokens etc. He didn't know it wasn't ok to commit these into GitHub.
- At his project meetups with partners I had to repeatedly ask him to stop googling gifs and pay attention to the talks.
- He complained that we don't have 3 hour lunch breaks like his last place.
- He once copied and pasted the same function 450 times into a file as a load test ... are loops too mainstream nowadays?
You see C is our winner, because after 6 painful months (companies internal process / requirements) he actually achieved nothing. I really mean that, nothing. Every thing was so broken, so insecure / wide open, built without any kind of common sense or standards I had to delete it all and start again ... it took me 2 weeks.
I hope you've all enjoyed this series and will join me in praying for the return of my sanity ... I do miss it a lot.
Yours truly,

I've had my share of incompetent coworkers. In order of appearance:
1. A full stack dev. This one guy never, and I mean NEVER uses relationships in their tables. No indexing, no keys, nada. Couple of months later he was baffled why his page took ten seconds to load.
2. The same dev as (1). Requirement was to create some sort of "theme" feature for a web app. Hacked it by putting !important all over the place.
3. The same dev again. He creates several functions that if the data exists returns a view, and if it doesn't, "echo '0'". No, not return 0 or return false or anything, but fucking echo. This was PHP. If posted a rant about this a few months ago.
4. Same dev, has no idea what clean code is. No, not just reusable functions, he doesn't even get indenting right. Some functions have 4 spaces, some 2 tabs, some 6 tabs! And this is inside the same function. God wait until he tries Python...
5. Same dev now suggests that he become the PM. GM approves (very small company). Assigns me to travel to a client since they needed "technical assistance about the API". Was actually there to lead a UAT session.
Intermezzo, that guy went from fullstack dev to PM to sales (yes, one who calls clients to offer products) to business development, to product analyst in the span of two years.
After a year and a half there, I quit.
6. New company, a "QA engineer" who also assumes the role as the product owner. Does absolutely no tests other than "functional tests" in which he NEVER produces any form of documentation. Not even a set of test cases. He goes by "intuition".
7. Same guy as (6), hands me requirements for a feature. By "hands me" I mean he did that verbally. No spec documents, no slack chat, no Trello card. I ended up writing it as a card in Trello. Fast forward to the due date, he flips out because that wasn't what he wanted. Showed him the card. He walked away, without thinking of a solution how this mess should be handled.
Despite all this, I really don't want him (6&7) to leave the company. The devs get really stressed out at this job and he does make a really good person to laugh with/at. -
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.

Most hated language features?
PL/SQL:
• it exists
XSLT:
• it also exists
PHP:
• it still exists.
VB:
• Significant parentheses: `subName` calls the subroutine, and `subName()` calls the subroutine and gets a return value. If you use the wrong invocation, it yells at you. Why!?
• For reasons unknown, you can only have `sleep` appear once per codebase. (So put it in a function!)
Ruby:
• It’s bloody easy to write code with absolute shit performance, and it kind of feels encouraged because of just how easy Ruby makes everything. Less critical thinking means worse performance, and Ruby’s blissful elegance encourages mental laziness.
• Minor: You cannot pass a hash as the first method parameter without enclosing it in parentheses, ex:`method({key: value})`. This is due to the ambiguous case between passing a hash argument and a (curly) block/proc (`method {|args| code}`). This could be remedied pretty easily with a little bit of look ahead.
• Minor: There is no `elsif` for `unless` (a negated if). Why? No reason given.
Python:
• no block endings, so nested code can be extremely difficult to follow.

WASM was a mistake. I just wanted to learn C++ and have fast code on the web. Everyone praised it. No one mentioned that it would double or quadruple my development time. That it would cause me to curse repeatedly at the screen until I wanted to harm myself.
The problem was never C++, which was a respectable if long-winded language. No no no. The problem was the lack of support for 'objects' or 'arrays' as parameters or return types. Anything of any complexity lives on one giant Float32Array which must surely bring a look of disgust from every programmer on this muddy rock. That is, one single array variable that you re-use for EVERYTHING.
Have a color? Throw it on the array. 10 floats in an object? Push it on the array - and split off the two bools via dependency injection (why do I have 3-4 line function parameter lists?!). Have an image with 1,000,000 floats? Drop it in the array. Want to return an array? Provide a malloc ptr into the code and write to it, then read from that location in JS after running the function, modifying the array as a side effect.
My- hahaha, my web worker has two images it's working with, calculations for all the planets, sun and moon in the solar system, and bunch of other calculations I wanted offloaded from the main thread... they all live in ONE GIANT ARRAY. LMFAO.If I want to find an element? I have to know exactly where to look or else, good luck finding it among the millions of numbers on that thing.
And of course, if you work with these, you put them in loops. Then you can have the joys of off-by-one errors that not only result in bad results in the returned array, but inexplicable errors in which code you haven't even touched suddenly has bad values. I've had entire functions suddenly explode with random errors because I accidentally overwrote the wrong section of that float array. Not like, the variable the function was using was wrong. No. WASM acted like the function didn't even exist and it didn't know why. Because, somehow, the function ALSO lived on that Float32Array.
And because you're using WASM to be fast, you're typically trying to overwrite things that do O(N) operations or more. NO ONE is going to use this return a + b. One off functions just aren't worth programming in WASM. Worst of all, debugging this is often a matter of writing print and console.log statements everywhere, to try and 'eat' the whole array at once to find out what portion got corrupted or is broke. Or comment out your code line by line to see what in forsaken 9 circles of coding hell caused your problem. It's like debugging blind in a strange and overgrown forest of code that you don't even recognize because most of it is there to satisfy the needs of WASM.
And because it takes so long to debug, it takes a massively long time to create things, and by the time you're done, the dependent package you're building for has 'moved on' and find you suddenly need to update a bunch of crap when you're not even finished. All of this, purely because of a horribly designed technology.
And do they have sympathy for you for forcing you to update all this stuff? No. They don't owe you sympathy, and god forbid they give you any. You are a developer and so it is your duty to suffer - for some kind of karma.
I wanted to love WASM, but screw that thing, it's horrible errors and most of all, the WASM heap32.7 -
EEEEEEEEEEEE Some fAcking languages!! Actually barfs while using this trashdump!
The gist: new job, position required adv C# knowledge (like f yea, one of my fav languages), we are working with RPA (using software robots to automate stuff), and we are using some new robot still in beta phase, but robot has its own prog lang.
The problem:
- this language is kind of like ASM (i think so, I'm venting here, it's ASM OK), with syntax that burns your eyes
- no function return values, but I can live with that, at least they have some sort of functions
- emojies for identifiers (like php's $var, but they only aim for shitty features so you use a heart.. ♥var)
- only jump and jumpif for control flow
- no foopin variable scopes at all (if you run multiple scripts at the same time they even share variables *pukes*)
- weird alt characters everywhere. define strings with regular quotes? nah let's be [some mental illness] and use prime quotes (‴ U+2034), and like ⟦ ⟧ for array indexing, but only sometimes!
- super slow interpreter, ex a regular loop to count to 10 (using jumps because yea no actual loops) takes more than 20 seconds to execute, approx 700ms to run 1 code row.
- it supports c# snippets (defined with these stupid characters: ⊂ ⊃) and I guess that's the only c# I get to write with this job :^}
- on top of that, outdated documentation, because yea it's beta, but so crappin tedious with this trail n error to check how every feature works
The question: why in the living fartfaces yolk would you even make a new language when it's so easy nowadays to embed compilers!?! the robot is apparently made in c#, so it should be no funcking problem at all to add a damn lua compiler or something. having a tcp api would even be easier got dammit!!! And what in the world made our company think this robot was a plausible choice?! Did they do a full fubbing analysis of the different software robots out there and accidentally sorted by ease of use in reverse order?? 'cause that's the only explanation i can imagine
Frillin stupid shitpile of a language!!! AAAAAHHH
see the attached screenshot of production code we've developed at the company for reference.
Disclaimer: I do not stand responsible for any eventual headaches or gauged eyes caused by the named image.
(for those interested, the robot is G1ANT.Robot, https://beta.g1ant.com/)4 -
"I'm almost done, I'll just need to add tests!"
Booom! You did it, that was a nuke going off in my head.
No, you shouldn't just need to add tests. The tests should have been written from the get go! You most likely won't cover all the cases. You won't know if adding the tests will break your feature, as you had none, as you refactor your untested mess in order to make your code testable.
When reading your mess of a test case and the painful mocking process you went through, I silently cry out into the void: "Why oh why!? All of this suffering could have been avoided!"
Since most of the time, your mocking pain boils down to not understanding what your "unit" in your "unit test" should be.
So let it be said:
- If you want to build a parser for an XML file, then just write a function / class whose *only* purpose is: parse the XML file, return a value object. That's it. Nothing more, nothing less.
- If you want to build a parser for an XML file, it MUST NOT: download a zip, extract that zip, merge all those files to one big file, parse that big file, talk to some other random APIs as a side-effect, and then return a value object.
Because then you suddenly have to mock away a http service and deal with zip files in your test cases.
The http util of your programming language will most likely work. Your unzip library will most likely work. So just assume it working. There are valid use cases where you want to make sure you acutally send a request and get a response, yet I am talking unit test here only.
In the scope of a class, keep the public methods to a reasonable minimum. As for each public method you shall at least create one test case. If you ever have the feeling "I want to test that private method" replace that statement in your head with: "I should extract that functionality to a new class where that method public. I then can create a unit test case a for that." That new service then becomes a dependency in your current service. Problem solved.
Also, mocking away dependencies should a simple process. If your mocking process fills half the screen, your test setup is overly complicated and your class is doing too much.
That's why I currently dig functional programming so much. When you build pure functions without side effects, unit tests are easy to write. Yet you can apply pure functions to OOP as well (to a degree). Embrace immutability.
Sidenote:
It's really not helpful that a lot of developers don't understand the difference between unit, functional acceptance, integration testing. Then they wonder why they can't test something easily, write overly complex test cases, until someone points out to them: No, in the scope of unit tests, we don't need to test our persistance layer. We just assume that it works. We should only test our businsess logic. You know: "Assuming that I get that response from the database, I expect that to happen." You don't need a test db, make a real query against that, in order to test that. (That still is a valid thing to do. Yet not in the scope of unit tests.)rant developer unit test test testing fp oop writing tests get your shit together unit testing unit tests8 -
The manager and selfperceived omnipotent cult leader was the worst kind of businessman. Slimey and trecherous, zero sense of ethics, but felt holier than the pope because he "helped" his weakling herd of piteous employees.
These employees were smart kids, most of them in their late teens. All of them legally disabled. There was this kid who gobbled up ritalin like candy, a boy who had received his measles shots and turned socially awkward (/s), a chubby girl who could name all the hex colors of her chocolate stained shirt... you know, what we call skilled developers in the industry.
Fiftyfive of them.
They were awesome, awkward highschool dropouts, like I had been a decade earlier. They worked 50h a week. They had great humor, were passionate, devoured information about new technologies, and they built custom websites from scratch in no time. I had to lead this flock, and felt honored to work with them.
Then things started to smell funny.
I discovered all 55 of their workstations ran pirated software, from Windows to Adobe CS. I'm not without sin in that regard, but as a company it's just plain stupid.
Clients were treated like shit. I mean, we all feel like punching a client in the face sometimes, but I'm taking about unjustified debt collections paired with death threats.
Then I found out these kids were often disappearing for a few months, only to return months later.
I started digging, and discovered they were all working reintegration internships (because they were on below minimum wage disability payments), at almost zero cost to my employer.
After 6 months, my boss gave them a negative recommendation, they were all too "sick" to function in normal jobs.
Then they were rotated to a shadow company, doing the same work for another 6 months, and so on to a third company.
He broke these kids, talked them down, made them feel worthless. He threatened the ones who understood what was happening.
I ended up bringing the company down, with the CEO and two government officials jailed for fraud and corruption.
Some employees were quite mad about it, at least at first — I was the shepherd who abandoned his sheep. Luckily, most found better paid positions in no time.
Truly one of the most fucked up and difficult situations I've been in.6 -
I have this one chick on Twitter that she used to be a fellow classmate of mine while I was going for my Bachelors degree.
She would always bitch and complain about how the teachers we had were horrible at teaching. I had to interact with her because of one assignment and EVERYONE in the team was good and well with the items, we finished it rather quick (build a terminal emulator) and we were just thinking about ways to make it look cooler. It was challenging to be honest, but everyone was so interested in it and had all the materials requires plus a very nice instructor to go with that would be overly happy to answer questions and provide additional content, the instructor in question made no book requirement for the class and provided instead free resources, be it video content or his own code on the matter to make sure that everyone got it.
Dude was amazing (most of my university instructors were truly fascinating or people that had worked for very interesting projects) and so when she complain that the guy "had no idea how to teach" I decided to investigate a little.
You see, she had NEVER taken any consideration that maybe you should advance your studies in the field, particularly in programming, by doing your own fucking research. No, the professor is not supposed to hold your fucking hand while you are trying to understand how a fucking function IN FUCKING PYTHON works, dude gave a full length lecture and the only retard that did not understood the topic: was you. He went to you to help you and instead you gave the man an attitude because for some fucking reason he was accounted for your own fucking stupidity. Motherfucker was there for more than 30 minutes trying to explain to this dumb chick the nuances of def hello(): return "hey there" and for some fucking reason you were too daft to understand that.......
The chick complained to us in the team how because of work she had NO time whatsoever to dedicate to reading programming or general software engineering materials......yet her twitter was FULL of book reviews concerning novels and self help books and bullshit like that.
If you are like that, and blame it on your teachers: fuck-you.
To this day she still bitches about the teachers from time to time, I legit told her once that she had no business attending a C.S degree.
Do you think you can get into Julliard without ever touching a fucking instrument? no. Do you think you can tell some Terence Fletcher-throwing-a-chair-at-your motherfucker to show you how to position your hands on a drumstick or what keys to press on a piano? FUCK NO.
If you were being DAFT on a ProGraMmiNg101 for which they picked Python to be the language to use and blamed your fucking stupidity to a teacher then yet again: FUCK-YOU6 -
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 -
Two big moments today:
1. Holy hell, how did I ever get on without a proper debugger? Was debugging some old code by eye (following along and keeping track mentally, of what the variables should be and what each step did). That didn't work because the code isn't intuitive. Tried the print() method, old reliable as it were. Kinda worked but didn't give me enough fine-grain control.
Bit the bullet and installed Wing IDE for python. And bam, it hit me. How did I ever live without step-through, and breakpoints before now?
2. Remember that non-sieve prime generator I wrote a while back? (well maybe some of you do). The one that generated quasi lucas carmichael (QLC) numbers? Well thats what I managed to debug. I figured out why it wasn't working. Last time I released it, I included two core methods, genprimes() and nextPrime(). The first generates a list of primes accurately, up to some n, and only needs a small handful of QLC numbers filtered out after the fact (because the set of primes generated and the set of QLC numbers overlap. Well I think they call it an embedding, as in QLC is included in the series generated by genprimes, but not the converse, but I digress).
nextPrime() was supposed to take any arbitrary n above zero, and accurately return the nearest prime number above the argument. But for some reason when it started, it would return 2,3,5,6...but genprimes() would work fine for some reason.
So genprimes loops over an index, i, and tests it for primality. It begins by entering the loop, and doing "result = gffi(i)".
This calls into something a function that runs four tests on the argument passed to it. I won't go into detail here about what those are because I don't even remember how I came up with them (I'll make a separate post when the code is fully fixed).
If the number fails any of these tests then gffi would just return the value of i that was passed to it, unaltered. Otherwise, if it did pass all of them, it would return i+1.
And once back in genPrimes() we would check if the variable 'result' was greater than the loop index. And if it was, then it was either prime (comparatively plentiful) or a QLC number (comparatively rare)--these two types and no others.
nextPrime() was only taking n, and didn't have this index to compare to, so the prior steps in genprimes were acting as a filter that nextPrime() didn't have, while internally gffi() was returning not only primes, and QLCs, but also plenty of composite numbers.
Now *why* that last step in genPrimes() was filtering out all the composites, idk.
But now that I understand whats going on I can fix it and hypothetically it should be possible to enter a positive n of any size, and without additional primality checks (such as is done with sieves, where you have to check off multiples of n), get the nearest prime numbers. Of course I'm not familiar enough with prime number generation to know if thats an achievement or worthwhile mentioning, so if anyone *is* familiar, and how something like that holds up compared to other linear generators (O(n)?), I'd be interested to hear about it.
I also am working on filtering out the intersection of the sets (QLC numbers), which I'm pretty sure I figured out how to incorporate into the prime generator itself.
I also think it may be possible to generator primes even faster, using the carmichael numbers or related set--or even derive a function that maps one set of upper-and-lower bounds around a semiprime, and map those same bounds to carmichael numbers that act as the upper and lower bound numbers on the factors of a semiprime.
Meanwhile I'm also looking into testing the prime generator on a larger set of numbers (to make sure it doesn't fail at large values of n) and so I'm looking for more computing power if anyone has it on hand, or is willing to test it at sufficiently large bit lengths (512, 1024, etc).
Lastly, the earlier work I posted (linked below), I realized could be applied with ECM to greatly reduce the smallest factor of a large number.
If ECM, being one of the best methods available, only handles 50-60 digit numbers, & your factors are 70+ digits, then being able to transform your semiprime product into another product tree thats non-semiprime, with factors that ARE in range of ECM, and which *does* contain either of the original factors, means products that *were not* formally factorable by ECM, *could* be now.
That wouldn't have been possible though withput enormous help from many others such as hitko who took the time to explain the solution was a form of modular exponentiation, Fast-Nop who contributed on other threads, Voxera who did as well, and support from Scor in particular, and many others.
Thank you all. And more to come.

'Hey I found a bug in your code, it's probably a typo, see here.'
Me: Oh right, yeah. How stupid of me. Thanks, I'll push it.
'It's okay. You can push it or I can do it too after you push the changes we just discussed. I actually simplified one of your methods.'
Me: You, what... ?
(You crammed multiple lines in a single line with your stupid as fuck, rigid constructs, removing my error handling, loosely coupled service, in the name of simplification?)
' Yeah it's just four lines in a single function now, no need to call the function again and again.'
Me: (No... Just no. This totally undos whatever little I could do to avoid supporting your idiotic object in the first place.)
Oh... okay, we'll see. I'll let you know.
What life.
Life in a company full of ignorant, inflated egos is no joke.
Details:
I created a service that reads a configuration file and returns the configuration. This person needs five entries for his app logic. He collected them in a object. Quite alright. Except that the class prototype is shitty. I, like a normal person, made my service return a value based on input. I was asked to incorporate this awful object so that I can return the five entries together, which is awful because the service is not supposed to know about how the entries are clubbed. It should most certainly not know about the data members of the object!4 -
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 -
Not sure if it's the worst code review but it's a recent one.
We don't really do code reviews where I work unfortunately but my coworker used my framework for the first time (build some nice composer libraries for cmdline projects) and asked if I could make them do autoloading.
He never used namespaces before so I was glad to help him out.
What I saw was a dreadful mess. His project was called "scripts" so good luck picking a namespace...
Than it was all lose functions in the executable file. All those functions are however called by a class in another file (if they where not calling eachother as a cascading mess). That class was extending an abstract class from my library as instructed. However I never imagined my lib being raped like that.
The functions themselves are a horrible mess. Nothing uniform completely different style (our documentation states PSR's should be used).
Parameters counts higher than 5.
Variable names like Object and Dobject (in calling function Dobject is Object but it needs a fresh one.
If statements on parameters that need basically split it in two (should simply be to functions)
If else statement with return of same variable as a single line (sane people use ternary for that)
Note that I said functions. All of it should have been OO and methods. Would have saved at least some of the parameter hell.
I could go on and on. Do I think the programmer is bad yes (does not even grasp interfaces, dep injection, foreach loops). Is this his best work no. He said that for a one of script like this it just has to work. Not going to be used elsewhere. I disagree as it is a few thousand lines of code that others have to read too.2 -
Fuck Wordpress, Fuck Wordpress's PHP
I'm so fucking tired of everything in this godforsaken CMS. Import a JS File? Sure, just add a *completely obvious* line into a very specific PHP File, where you'll have to specify a lot of "useful" parameters. No, I somehow DON'T want to specify that I don't wand jQuery in every import. And don't even get me started on Content Delivering. Embed CSS? Sure, just write the fucking whole path to the file, or use the broken get_stylesheet_uri() Function. Embed an Image? Sure, let me just go to the Backend and wait 6 Minutes for this bullshitty System to upload the image and then copy the hard-coded Link. Oh, you want to remove googleapi embeds? Sure, let me just fuck up your whole Website in return.
You want jQuery? Well instead of using the "$" Symbol, you have to use the jQuery() Function. Except when you don't have to, which is 100% random each time you reload the page. Oh, you actually did import a JS File? Sure, let me just not run it. Thank you fucking piece of shit thats calling itself "WordPress" and fuck you and everyone whos actively encouraging its usage1 -
Anyone here knows whether this is valid?
This is the default code for a new Visual Studio C++ Console Project.20 -
I really like helping other learn how to use a programming language or solve problems on general. I often go out of my way and stop working on my hobby projects, just to help someone.
Thag being said, I'm no prgramming god. I myself am striving to become a better programmer.
I make mistakes, I can't always help you, I am still learning, but I only have good intentions. And you are by no means obligated to follow my advice. Quite the contrary, fight me, try to prove me wrong or say point out possible flaws. THINK ABOUT WHAT I TELL YOU. DON'T JUST BLINDLY FOLLOW MY ADVICE AND BITCH ON ME LATER.
This happens rather often and I can see why you want to blame me. And I can't deny that part of this is also my fault.
Situations like these don't really tilt me.
But today someone had the fucking nerve to pop a file into the chat and get mad at me for sugvesting a cleaner, shorter and more efficient solution. LIKE I DON'T FUCKING CARE THAT IT TOOK YOU A WHOLE DAY TO IMPLEMENT SOMETHING I CAN DO BETTER IN MINUTES, I JUST WANT TO HELP YOU.
But the best thing I get afterwards: "But you told me to do it like that" BITCH WHAT!?
I have chat logs telling me loud and clear that the concept we never talked about before in private nor on a public server (bless discord's search function). And I will not accept your lousy excuse of having me cobfused with someone. You disrespected me greatly, you put words in my mouth, just to justify your pity anger, when I'm trying to help you?!
Get crucified and put on a shooting range!
I offer you out of pure goodwill. Something you'd normally have to pay for. And this is the treatment I get in return?
Just rm -rf your disastrous, dd -if=/dev/urandom your harddrive and sod off!2 -
How do you test unreachable code or part that is considered an edge case?
For example I catch exceptions in case IO failed and data was not written on database, but that only happens if hardware failure, or no disk space left, how do I mimic that?
I also have unreachable code for example, in one layer I fetch data (lets call it function x) and always return success result unless item not found I throw KeyNotFound exception. But in the calling function I handle the case of Status == Failed
Just in-case in the future I change function x and start returning failed status, so my logic already written but never reachable14 -
Can we take a moment to recognize how absolutely retarded JS' event system is?
Events aren't objects. No, they're managed by an object, and identified by a string.
To subscribe to an event, you call object.addEventListener(name, callback). Because for some reason we can't just have an event object. Events MUST have an owner.
But to unsubscribe you don't call the function addEventListener returned, you don't use the token it returned either. No, you pass the same function to removeEventListener.
Because we don't use serializable tokens like in PP, and we don't return functions like in FP, no, we use functions as tokens, realising idiomatic DFP.2 -
Long story short:
My system need to talk with a 3rd party PoS API. The provided doc is pretty useless and with few errors.. nonetheless I came to finish the 99% of the job.
I was stuckd on the 1%, one frickin function.
Everytime I would call the endpoint I would receive...NOTHING. Just a 200.
I've spent like 5 hours trying everything, even sending wrong params...nothing...
Always 200 and nothing else.
Apparently, for an entire nation and the IT Company behind them, is ok to have A PAYMENT API TO RETURN VOID AND A 200 NO MATTER WHAT.
I got the luck/unluck that the main developer of such piece of art came in the office and I've almost throw him out the window (we are at 26th floor).
FUCK OFF DUDE. YOU AND ALL THE OTHERS THAT DO LIKE YOU DO.
P.S. in this days I'll try to write the full story, but it's hard without giving many details...small anticipation: 1.5 months of work and nothing but red bull and coffee...4 -
Sometimes in our personal projects we write crazy commit messages. I'll post mine because its a weekend and I hope someone has a well deserved start. Feel free to post yours, regex out your username, time and hash and paste chronologically. ISSA THREAD MY DUDES AND DUDETTES

Just a quickie
I dont know what im committing...3 -
Heres a fairly useless but interesting tidbit:
if i = n
then
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
then r%a will (almost*) always return 0. when n = floor(a/2) for the lowest non-trivial factor of a two factor product.
Thats not really the interesting bit though. The interesting bit is the result of r will always be some product with a *larger* factor tree that includes the factor A of p, but not p's other larger factor, B.
So, useless from what I can see. But its an interesting function on its own, simply because of what it does.
I wrote a script to test it. For all two-factor products of the first 1000 primes, (with no repeating combinations, so if we calculated say, 23*31, we skip 31*23), only 3262 products failed this little formula, out of half a million.
All others reliably returned 0 for the following..
~~~
i = floor(a/2)
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
r%a
~~~
The distribution of failures was *very* early on in the set of factors, and once fixed at the value of 3262, stopped increasing for the rest of the run.
I didn't calculate if some primes were more likely to cause a product to fail or not. Nor the factor trees, nor if the factor trees had any factors in common between products, or anything of that nature.
All in all I count this as a worthwhile experiment.
If you want to run the code yourself, I posted it to pastebin here:

Tried wolfram alpha just to see what it says, but apparently not much. Wish it could tell me more.40
