I tutor people who want to program, I don't ask anything for it, money wise, if they use my house as a learning space I may ask them to bring cookies or a pizza or something but on the whole I do it to help others learn who want to.

Now this in of itself is perfectly fine, I don't get financially screwed over or anything, but...

Fuck me if some students are horrendous!

To the best of my knowledge I've agreed to work with and help seven individuals, four female three male.

One male student never once began the study work and just repeatedly offered excuses and wanted to talk to me about how he'd screwed his life up. I mean that's unfortunate, but I'm not a people person, I don't really feel emotionally engaged with a relative stranger who quite openly admits they got addicted to porn and wasted two years furiously masturbating. Which is WAY more than I needed to know and made me more than a little uncomfortable. Ultimately lack of actually even starting the basic exercises I blocked him and stopped wasting my time.

The second dude I spoke to for exactly 48 hours before he wanted to smash my face in. Now, he was Indian (the geographical India not native American) and this is important, because he was a friend of a friend and I agreed to tutor however he was more interested in telling me how the Brits owed India reparations, which, being Scottish, I felt if anyone was owed reparations first, it's us, which he didn't take kindly too (something about the phrase "we've been fucked, longer and harder than you ever were and we don't demand reparations" didn't endear me any).

But again likewise, he wanted to talk about politics and proving he was a someone "I've been threatened in very real world ways, by some really bad people" didn't impress me, and I demonstrated my disinterest with "and I was set on fire once cos the college kids didn't like me".

He wouldn't practice, was constantly interested in bigging himself up, he was aggressive, confrontational and condescending, so I told him he was a dick, I wasn't interested in helping him and he can help himself. Last I heard he wasn't in the country anymore.

The third guy... Absolute waste of time... We were in the same computer science college class, I went to university and did more, he dossed around and a few years later went into design and found he wanted to program and got in touch. He completes the code schools courses and understandably doesn't quite know what to do next, so he asks a few questions and declares he wants to learn full stack web development. Quickly. I say it isn't easy especially if it's your first real project but if one is determined, it isn't impossible.

This guy was 30 and wanted to retire at 35 and so time was of the essence. I'm up for the challenge, and so because he only knows JavaScript (including prototypes, callbacks and events) I tell him about nodejs and explain that it's a little more tricky but it does mean he can learn all the basis without learning another language.

About six months of sporadic development where I send him exercises and quizzes to try, more often than not he'd answer with "I don't know" after me repeatedly saying "if you don't know, type the program out and study what it does then try to see why!".

The excuses became predicable, couldn't study, playing soccer, couldn't study watching bake off, couldn't study, couldn't study.

Eventually he buys a book on the mean stack and I agree to go through it chapter by chapter with him, and on one particular chapter where I'm trying to help him, he keeps interrupting with "so could I apply for this job?" "What about this job?" And it's getting frustrating cos I'm trying to hold my code and his in my head and come up with a real world analogy to explain a concept and he finally interrupts with "would your company take me on?"

I'm done.

"Do you want the honest unabridged truth?"

"Yes, I'd really like to know what I need to do!"

"You are learning JavaScript, and trying to also learn computer science techniques and terms all at the same time. Frankly, to the industry, you know nothing. A C developer with a PHD was interviewed and upon leaving the office was made a laughing stock of because he seemed to not know the difference between pass by value and pass by reference. You'd be laughed right out the building because as of right now, you know nothing. You don't. Now how you respond to this critique is your choice, you can either admit what I'm saying is true and put some fucking effort into studying cos I'm putting more effort into teaching than you are studying, or you can take what I'm saying as a full on attack, give up and think of me as the bad guy. Your choice, if you are ready to really study, you can text me in the morning for now I'm going to bed."

The next day I got a text "I was thinking about what you said and... I think I'm not going to bother with this full stack stuff it's just too hard, thought you should know."

Still the best example of
pass by value vs pass by reference

Google sucks!
No, not as e-mail or for privacy reasons. Sure, that too, but it comes with "free" stuff.

It sucks because it's breaking every possible record in the worst, shittiest, most insanely stupid APIs and integrations out there on the entire fucking planet!

It is comically stupid!

Aside from their LOVE of hard-deprecating APIs every few months, requiring constant, time consuming maintenance of every tool that integrates deeply with Google services, some of their APIs, for expensive stuff, look like they've been written by Bobby McFartface from 7th grade.

Take a look at DoubleClick Search (their ad performance reporting tool, that sure does sound like one). To upload custom, additional data, you must pass in a ton of parameter, and they REQUIRE some of them to have a specific, hardcoded value. What's the point in passing that parameter then you dickheads?!
But fine, so you uploaded some stuff using the API. Now you want to delete everything and try again after you fixed a bug - well you fucking CAN'T! You can't delete stuff, you can only mark them as "deleted" using an update call.
Bulk operations? Fuck no!
Can I just add on top? Well of course not! That will raise a ton of exceptions. Same message should be transmitted using the PUT, not POST request, in order to edit.
Can I send everything to PUT? Of course not! You can't edit something that's not there, dummy!

Can I see what's there so that I can update it, and add what's missing?
Well of course not! Why on Earth would you need to see what information is in there after you uploaded it? Who needs that anyway?

Simply send, pray, and hope that everything will be fine (it will not).

Like holy fucking crap, it can't get any more stupid!
Google is a huge pile of idiots who feed on only a single cow - the search engine.

It's times like these when I think that Google right now is the worst thing that exists for everyone in tech. It's dragging everyone down with their monopolies everywhere and complete idiocy in managing them.

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!

AHSKJGHALSKHGLKAHDSGJKASGH.

Last year, we had to do a big university project in randomly selected groups (5-6 students in every group).Three of the five guys were completely useless, I mean, both the other competent guy and me wrote around 20,000 lines of code each, the other ones wrote around 500 lines of code (combined).
After our first few meetings we quickly knew that we have to give them a small task which was so trivial that not even they can fuck it up. But we were wrong. Oh boy, so wrong.
They simply had to code the excel export of the data, which means they had to use two functions from a library and pass the correct data. But their solution was so bad, I lost faith in humanity and was fascinated by it at the same time.
For example, there was this simple class "Room", which had a few properties like size or number of seats and a few getter/setter etc. That was a core class and written by the other qualified guy. So how did the others fuck up the excel export? They somehow rewrote that class in German (although the other code was completely in English), implemented a function for each property that would write its value to a hardcoded cell in a hardcoded excel file.
And this was just the tip of the iceberg. Needlessly to say that I had to rewrite the whole export in the night before we had to present the project.

What happens in Vegas, stays in Vegas 😂

I was working with a stable installation of an elaborated platform. Some plugins were installed. After upgrading the installation by 2 patch level the customer registration was not working anymore.

In these two patch level a method in an interface got an additional optional parameter which had a major impact on the behaviour the implemented method. A plugin decorated the implementation without knowing about the new parameter. Therefore when calling the method the decorating class did not pass the new parameter in to the decorated implementation and the fallback value was given instead.

The caller expected the method to do something and did not branch into an alternative way but the default value disables the expected behaviour. Eventually nothing happened.

Breaking changes in patch levels woop di fucking do.

2 hour meeting to brainstorm ideas to improve our system health monitoring (logging, alerting, monitoring, and metrics)

Never got past the alerting part. Piss poor excuses for human being managers kept 'blaming' our logging infrastructure for allowing them to log exceptions as 'Warnings', purposely by-passing the alerting system.

Then the d-head tried to 'educate' everyone the difference between error and exception …frack-wad…the difference isn't philosophical…shut up.

The B manager kept referring to our old logging system (like we stopped using it 5 years ago) and if it were written correctly, the legacy code would be easier to migrate. Fracking lying B….shut the frack up.

The fracking idiots then wanted to add direct-bypass of the alerting system (I purposely made the code to bypass alerting painful to write)

Mgr1: "The only way this will work is if you, by default, allow errors to bypass the alerting system. When all of our code is migrated, we'll change a config or something to enable alerting. That shouldn't be too hard."
Me: "Not going to happen. I made by-passing the alert system painful on purpose. If I make it easy, you'll never go back and change code."
Mgr2: "Oh, yes we will. Just mark that method as obsolete. That way, it will force us to fix the code."
Me: "The by-pass method is already obsolete and the teams are already ignoring the build warnings."
Mgr1: "No, that is not correct. We have a process to fix all build warnings related to obsolete methods."
Mgr2: "Yes. It won't be like the old system. We just never had time to go back and fix that code."
Me: "The method has been obsolete for almost a year. If your teams haven't fixed their code by now, it's not going to be fixed."
Mgr1: "You're expecting everything to be changed in one day. Our code base is way too big and there are too many changes to make. All we are asking for is a simple change that will give us the time we need to make the system better. We all want to make the system better…right?"
Me: "We made the changes to the core system over two years ago, and we had this same conversation, remember? If your team hasn't made any changes by now, they aren't going to. The only way they will change code to the new standard is if we make the old way painful. Sorry, that's the truth."
Mgr2: "Why did we make changes to the logging system? Why weren't any of us involved? If there were going to be all these changes, our team should have been part of the process."
Me: "You were and declined every meeting and every attempt to include your area. Considering the massive amount of infrastructure changes there was zero code changes required by your team. The new system simply worked. You can't take advantage of the new features which is why we're here today. I'm here to offer my help in any way I can with the transition."
Mgr1: "The new logging doesn't support logging of the different web page areas. Until you can make that change, we can't begin changing our code."
Me: "Logging properties is just a name+value pair dictionary. All you need to do is standardize on a name and how you add it to the collection."
Mgr2: "So, it's not a standard field? How difficult would it be to change the core assembly? This has to be standard across all our areas and shouldn't be up to the developers to type in anything they want."
- Frack wads smile and nod to each other like fracking chickens in a feeding frenzy
Me: "It can, but what will you call this property? What controls its value?"
- The look I got from both the d-bags I could tell a blood vessel popped.
Mgr1: "Oh…um….I don't know…Area? Yea … Area."
Mgr2: "Um…that's not specific enough. How about Page?"
Mgr1: "Well, pages can cross different areas, and areas cross different pages…what do you think?"
Me: "Don't know, don't care. It's up to you. I just need a name."
Mgr2: "Modules! Our MVC framework is broken up in Modules."
DevMgr: "We already have a field for Module. It's how we're segmenting the different business processes"
Mgr1: "Doesn't matter, we'll come up with a name later. Until then, we won't make any changes until there is a name."
DevMgr: "So what did we accomplish?"
Me: "That we need to review the web's logging and alerting process and make sure we're capturing errors being hidden as warnings."
Mgr1: "Nooo….we didn't accomplish anything. This meeting had no agenda and no purpose. We should have been included in the logging process changes from day one."
Mgr2: "I agree, I'm not sure why we're here"
Me: "This was a brainstorming meeting as listed in the agenda. We've accomplished 2 of the 4 items. I think we've established your commitment to making the system better. Thank you all for coming."

- Mgr1 and 2 left without looking at me or saying a word.

Best debugging trick ever:

Wear your fucking glasses while coding so that you do not mistake COMMA(,) with a DOT (.).

So by
1. Doing that (which obviously aren't a huge number) and
2. Cleaning my screen (yes that).

I was able to wrap my head around the issue that almost wasted one day.
So what I intended to pass as string concatenation join operation value actually was being passed as an argument to the underlying function (that wasn't taking care of it and returning a timestamp from thin air).

Murphy's Law in production and practice.
Nice!

Depressing music continues......!

In the 90s most people had touched grass, but few touched a computer.

In the 2090s most people will have touched a computer, but not grass.

But at least we'll have fully sentient dildos armed with laser guns to mildly stimulate our mandatory attached cyber-clits, or alternatively annihilate thought criminals.

In other news my prime generator has exhaustively been checked against, all primes from 5 to 1 million. I used miller-rabin with k=40 to confirm the results.

The set the generator creates is the join of the quasi-lucas carmichael numbers, the carmichael numbers, and the primes. So after I generated a number I just had to treat those numbers as 'pollutants' and filter them out, which was dead simple.

Whats left after filtering, is strictly the primes.

I also tested it randomly on 50-55 bit primes, and it always returned true, but that range hasn't been fully tested so far because it takes 9-12 seconds per number at that point.

I was expecting maybe a few failures by my generator. So what I did was I wrote a function, genMillerTest(), and all it does is take some number n, returns the next prime after it (using my functions nextPrime() and isPrime()), and then tests it against miller-rabin. If miller returns false, then I add the result to a list. And then I check *those* results by hand (because miller can occasionally return false positives, though I'm not familiar enough with the math to know how often).

Well, imagine my surprise when I had zero false positives.

Which means either my code is generating the same exact set as miller (under some very large value of n), or the chance of miller (at k=40 tests) returning a false positive is vanishingly small.

My next steps should be to parallelize the checking process, and set up my other desktop to run those tests continuously.
Concurrently I should work on figuring out why my slowest primality tests (theres six of them, though I think I can eliminate two) are so slow and if I can better estimate or derive a pattern that allows faster results by better initialization of the variables used by these tests.

I already wrote some cases to output which tests most frequently succeeded (if any of them pass, then the number isn't prime), and therefore could cut short the primality test of a number. I rewrote the function to put those tests in order from most likely to least likely.

I'm also thinking that there may be some clues for faster computation in other bases, or perhaps in binary, or inspecting the patterns of values in the natural logs of non-primes versus primes. Or even looking into the *execution* time of numbers that successfully pass as prime versus ones that don't. Theres a bevy of possible approaches.

The entire process for the first 1_000_000 numbers, ran 1621.28 seconds, or just shy of a tenth of a second per test but I'm sure thats biased toward the head of the list.

If theres any other approach or ideas I may be overlooking, I wouldn't know where to begin.

Of course, I just swiped the wrong way on my fucking laptop trackpad and list everything I just typed. FUCKING MARVELOUS.

TL;DR: Teacher stopped me from being productive. Principal almost called cops on me. Nearly threw chair at librarian.

So I'm at school yesterday, and we have a presenter in 2nd hour, so naturally, I'm gonna be on my computer doing things for other classes at the same time. Efficiency. Teacher doesn't like it, I refuse to put the computer away telling her that I'll be more productive and still pay attention, which HAS BEEN PROVEN MIND YOU, but she ends up calling security on me and I get sent down to the principal's office.

I talk to him, and he says 'Yeah, I know it's in the way, but you have to follow the directive given by the teachers.' Fine, fuck it. Won't go to her class for third hour. (I have her twice in a row for two different classes.) Next day.

I walk in, asking her if she's gonna do the same thing she did yesterday, hoping that she realized her error and will fix it, but no. She says I STILL can't have the computer out. I'm sorry, do you not realize I have 6 other fucking classes, most of which are required to graduate, unlike YOURS, as well as a FUCKING COLLEGE CLASS TONIGHT?! She gives the ultimatum. 'Obey or leave.' Fine, I'll leave. I go to the principal's office again, he must have a stick up his ass or something today because he's not budging. We argue for a while and he gives a WORSE ultimatum: 'Obey, Go to the Library, In House Suspension, or I'll call the police.' What the actual FUCK MAN?! You're gonna call the POLICE on a NONVIOLENT STUDENT?! Are you fucking MAD? I keep trying to tell him that there's an easy solution to this, but as he's getting up to call the cops, I say 'Fine! I'll go to the library!' He follows me over to make sure I don't kill anyone on the way.

I slam the door to the library open, and when I walk in, the librarian is there at her computer, and she asks 'Where are you coming from?' 'Principal!' 'I need a pass-' 'Well, I'm sorry, I can't exactly get anything for you right now, I was just sent down here.' She says 'Either way, I need some kind of note or pas-' 'Listen, I'm not in the mood for any of this right now. Please, just leave me be.' She then tries to say something, but I cut her off quickly, 'Just back off and leave me alone right now. The more you push it, the more you're gonna make me want to throw this chair!' Imagine the volume just gradually getting louder on that last one. She quickly runs out and talks to the security desk or something, which is right outside the library door, but she's the only one who comes in, thankfully. I was expecting to be fucking dragged out for no good reason. I'm loud, not violent. I have no history of violence.

So yeah. Here I am in the school library, angrily tapping away at my keyboard, trying not to throw the entire table to the fucking moon. All because this broken-ass public school system has no idea how to deviate from the norm when it's actually productive and efficient to do so. And now, the obligatory:

FUCKING PIECES OF SHIT WHY DON'T YOU REALIZE THAT YOU ARE COMPLETELY WRONG IN EVERY SINGLE THING YOU ARE DOING YOU IDIOTIC SCUM-FILLED MEAT SACKS OF NO FORSEEABLE VALUE! FUCK!

Today I had an, argument with my C# teacher because he believes that reference types are passed by value

I posted a link on Facebook to MSDNs page about it, but somehow some guy in my class still argued for it being pass by value. The reason he says so is because the value is the reference, even though it's quite literally a reference.

It's a reference to a variable rather than, a value.

Kindly
Fuck
Off

Am I the only one who's a final year undergraduate, but isn't sure he/she knows enough about programming and comp sci as they should?

Like I recently went for an interview with a company, and they asked what's the difference between pass by reference and pass by value. Now, this is probably a very basic qs, so I was surprised when I couldn't answer this. So I'm really scared that I don't know enough, also I'm terrible in their group exercises too, I can't see how the others can do it so easily.

Hello Devrant. I really need a second opinion on this one. I work in this promising start-up and our current evaluation is about 10 mill $. I have a vesting opportunity in the company where I earn 2.5% of none dilutable shares in the company over three years. I also get salary of about 500$ a month just to survive. Though it is the plan that I get a decent salary once we have more funding secured.

I'm the CTO of the company where we are 10 employees in total and 5 are in the development team.

I've been programming for about one year now so I'm not that experienced and some of the guys I lead are much more experienced than me. Which is good because I grow my skills quickly, but it is a challenge sometimes.

I'm really in doubt if I have got a good deal in the company. I started working in February and back then the company was valued at around 1.5 mill $. I have always been loose about not demanding money right away and said to the CEO that we will figure that out about the money eventually and I trusted him blindly. When he gave the offer of 2.5% vesting I just accepted it right away, because I was a beginner in coding and I just wanted to learn. Also I was traveling around the world for a few months at the time and it was a great way to get a little money quickly.

I also study together with two colleges who are some of my best friends. We study business development at university and have round 1.5 year left. It's a lot of work
but we've managed to only study about 1 week in advance of the exams and still pass. So we all still working full time on the company.

I've never known how many shares the other guys had, but yesterday me and the other partners had a meeting about some contract and the CEO pointed out how many shares everybody had. I was stunned to hear that the my two other colleges that I study with have 10% each. And the reason for that is that they helped start the company from the beginning and I've only joined when it was around 6 months old. Still I find it difficult to that that it's fair that they should have 4 times as much as me. I would say the amount of value we provide to the company is about the same. One of the guys is only the son of the CEO, which should not change anything.

For me it's not all about the money but I don't want to be taken advantage of. I can't determine if I'm being overdramatic about this and whether it is a good deal or if it sucks and I should find another place to work. Also my studies at the University are pretty much intertwined with the company by now. All our school projects are something that creates value to the company and if I leave I would have to dramatically change the direction of my education.

I know that there is a lot of information here and that I'm not the best at writing, but what would you have done in my situation?

Possibly my favourite function is Clojure's "recur", which isn't really a function at all, but a special form that gives you a guaranteed tail-position call to the current function.

Basically what that means is you can write recursive functions (functions that call themselves) and know that you're not creating a potential stack overflow.

Um. Okay, I can feel people looking at me like 🤔 Basically what *that* means is: normally when a function calls another function, a "stack frame" is allocated, holding all the local variables for that call. If a function calls itself 1000 times, 1000 stack frames get allocated. "Tail call optimisation" is a process by which if you call yourself as the very last thing in a function, the language doesn't need to remember the current frame; it just has to pass the return value upwards. The trouble is, it's sometimes hard to notice that you've turned a tail-call optimisable function into a non-optimisable one. Clojure's recur keyword makes it explicit, and therefore safe: if you try to do anything with the return value of recur, it's an error.

PS I'm sure another language did explicit TCR first, but Clojure is where I first saw it.

I have been working as a freelancer for a little while now. I recently started using upwork. The first job that I got on upwork was titled: “help me”, the bio explained that it was with node.js. Later, during the interview, the client mentioned that it was 30+ hours a week. I was kind of confused. I had no idea what I was getting into. A little bit down the road, he provided me with the project. This is when I almost wanted to jump off a cliff. The code was organised as if it was a c or c++ app and I couldn’t follow anything. The guy thought that “pass by reference” was a thing in JS. I cried. Granted, with objects, there are some reference exceptions, but generally passed by value. The code is like spaghetti... I still have 2 months left on the contract. It’s awful.

I was wondering if anybody working for a larger Company in 3rd-Level faces the same personal problems as me?

We got alot of our own developed software and process. Regulary some Keyuser fucks something up by importing something wrong, which skews the master data. Its intended to be managed by the Keyuser.

Fast Forward, my Keyusers are so dumb, that they fuck up the master data import wrongfully. The process behind that then have wrong Data to operate (a numeric value neeeds to be set).

The Enduser then opens a Ticket for problem XYZ. Then the Keyuser forwards us the issue.

We already had that same issue X amount of times and its always the same reply. I made a FAQ, Knowledgebase entry, etc.

Nothing works, 2 weeks pass and a similiar tickets comes in...

Memory Capacity of the User exceeded after 1 Day. FML

Anybody facing the same shit?

I have a dream that one day whenever you pass / assign / apppend an object you can choose to pass by value or reference, regardless of the object being a primitive or a container (list, vector etc.) object

So I could stop waste my time and bang my head to my desk over such dumb problems this shit induces because language designers found making list to be passed by reference fun

I know such behavior is inherited from C's logic, and I don't give a fuck about any further explanation I might already know. What can be explained doesn't mean that's logical.
You give the choice to pass by value or reference for every object the same way or you do not at all, but no mixed shit.
Just, shut up and make it happen.
