  • Whi getting through college, I was always bummed that we have to learn a lot of stuff that seemed super irelevant to my future carreer, while also being annoying. Stuff like prolog, Phyro, Lisp, Assembly, or bunch of obscure math.

    It was only years later when I finally realized why it was important - the school wasn’t for teaching me to be the C#/Java programmer, but it taught me to be A programmer. I can pick up and start successfully writing anything I need, in any language, relatively quickly and without issues, nonmatter whether it’s functional, objective, or wharever style of language, because I’ve very probably already had to deal with, learn, understand and pass exams in language that is similar to it, since college made me learn a language from almost every style or flavor of languages there are.

    I was surprised when I first saw colleagues struggle with picking up languages other than the ones they work in, and that was when I finally realized why and how sneakily did the college make me a universal programmer without me noticing it. And that’s something that’s harder to get when self-taught, because you don’t get exams and it’s easier to miss the point and just skip courses on lisp, prolog or lambda calculus, because it seems irrelevant, but the different point of view and approach used when writing in those languahes is what will teach you the most.



  • 76% of all respondents are using or are planning to use AI tools in their development process this year, an increase from last year (70%). Many more developers are currently using AI tools this year, too (62% vs. 44%).

    What the fuck. That’s horrifying. I also though that every sensible workplace bans the use of AI.

    A friend was telling me about a discussion between CTO’s at a conference, where they were talking about whether it’s even worth it to hire junior developers anymore, since there’s a high risk of them just being “AI-raised”, without much (or any) experience of coding without AI. And, this survey result… I can see where they are coming from. The future of programming looks pretty bleak - our job will not be replaced. It will just get worse, with good developers being more of a rarity.

    And the amount of people who use vim or neovim as their IDE is surprisingly high. Is it skewed by sysadmins?


  • That’s a good question, and I never through about it like that. I think that the lack of documentation isn’t that much of a problem, rather that the code stands out in the project in that it is complex to understand and requires some more though, effort and imagination to grasp, since it’s generic with lot of interfaces and polymorphism.

    Now, that usually wouldn’t be much of an issue, however - the project is a game we’ve been actively working on in our spare time in a team of 2 programmers for the last 6 years, and we are all fed up with it and just want it to end. Most of the (pretty large by now) codebase is kind of simple - it’s a game code, after all, and since we started it when we were 20, there aren’t many overenginered ideas or systems, but everything is mostly written in the ugly, but simple and direct way, so if we had wanted to change something, we may have had to rewrite a part of it, but it never really needed much effort to understand what’s going on.

    But now I need to change this code, which is one of the only parts that requires some kind of imagination and actually sitting down and trying to understand it, and since my motivation about the project is so low, it’s a pretty large hurdle to cross. One that is also unnecessary, since most of the generalism isn’t needed and will never be used. But since the code is written in such extensible way, it’s hard to just hack up a simple and ugly solution somewhere into it and be done with it, without really figuring out what the hell is going on.

    A documentation wouldn’t help with that - it would still take the same amount of mental effort to be able to work with that code, which we generally lack in the project. I think that if I actually took the time to properly look through the code, figuring out what’s going on wouldn’t be too hard - the naming convention is pretty ok and it’s not that difficult, it just requires some mental effort.

    I’m not trying to make excuses, the code very probably has problems, I’m just trying to better sort my thoughts about why I have so much problems working on it. It probably has more to do with my motivation, rather than the code in itself, and the fact that the complexity here wasn’t required, and is now a needless hurdle that actually hinders progress. Not due to it’s quality, but do to unrelated motivation issues and us having to basically force ourselves to work on and finish the damn project.


  • There’s a piece of code in our hobby game project that I’ve written after attending classes in college about how to write clean and SOLID code. It’s the most overengineered piece of shit I’ve ever written. I’m not saying it’s the fault of the lectures, of course it’s on me being a little bit over zealous, but it does check all the boxes - It’s a simple “show selectable list of stuff”, follows MVC, it’s extensible without rewriting to adittional data-types and formats, extensible view that can show any part of data you need, generic, and in general it could be used anywhere we need, for any kind of data.

    There’s only one place where we need and use such list in our game.

    I needed to rewrite a part of it, since the UI changed drastically, to not need this kind of list, while also adding events into the process. I haven’t seen the code for almost 4 years, and it’s attrocious. Super hard to understand what’s going on, since it’s too generic, interfaces and classes all over the place, and while it probably would be possible to rewrite the views for the new features we need, it’s just so complex that I don’t have the mental capacity to again figure out how it was supposed to work and properly wire it up again.

    I’m not saying it’s fault of the classes, or SOLID. It’s entirely my fault, because the classes inspired and hyped me with ideas about what a clean code should look like, that I didn’t stop and think whether it’s really needed here, and went over-the-top and overengineered the solution. That’s what I’d say is the danger of such Clean Code books and classes - it’s easy to feel clever for making something that passes SOLID to the letter, but extensibility usually comes at a complexity, and it’s super important to stop and think - do I really need it?


  • One night when returning from a party at work, I’ve decided to stay a while longer in the tram to escort my co-workers to the tram central hub (which was like half an hour of tram ride), instead of getting out at my home, which was only 5 minutes from our workplace.

    When I got into the tram back home, there was an older guy with a carboard robot costume, who was talking to someone about his work in the theater. Because I find people like that interesting, I decided to move closer and sit next to them, so I can listen to their pretty interesting conversation. I’ve tripped and basically literally fell into their conversation, and the other guy left, so we started talking. It turned out he does a prop-guy on movies and for theater, and we hit it off pretty well. He also lived literally 3 minutes from my place, and we have decided to go have a few more beers at his home, which was basically a storage lot full of random stuff without much furniture - just random props, one bed, and a lot of beer.

    I’ve messaged my GF that I’ll be late, since I’m drinking with this pretty cool old guy, and send her a picture of the place. Her reponse was “Wait, isn’t that <name>?”. Turns out, he was a prop guy on a movie they were filming a lot of years ago at their old family house when she was young, and not only he was the most fun guy to be around there, always sneaking out to drink with them, but also briefly dated her (late) mother, so he’s basically her step-dad. Since he’s pretty old-school, no social networks, internet and barely a phone, we did exchange contacts and since then have seen him a few times, and it was always a treat, like getting us to the backstage of theater production. But the way we have met is so, so random and the odds of something like that happening are mind blowing. I usually don’t follow random people home, but here we have hit it off so well that we wanted to keep talking and it didn’t even felt weird.


  • I can’t decide whether this sentence is a joke or not. It has the same tone that triggers my PTSD from my CS degree classes and I also do recognize some of the terms, but it also sounds like it’s just throwing random science terms around as if you asked a LLM to talk about math.

    I love it.

    Also, it’s apparently also real and correct.









  • I might be wrong, but from how I understand it it probably wouldn’t help. Kernel drivers have a rigorous QA and cert by Microsoft if you want to get them signed, which is a process that may take a long time - longer than you can afford when pushing updates to AV/EDR to catch emerging threats. What Crowdstrike does to bypass this requirement is that the CS Falcon is just an engine, that loads, interprets and executes code from definition files. The kernel driver code then doesn’t need to change, so no need for new MS cert, and they can just push new definition files. So, they kind of have to deal with unsafe in this case, since you are executing a new code.



  • I wouldn’t call Crowdstrike a corporate spyware garbage. I work as a Red Teamer in cybersecurity, and EDRs are bane of my existence - they are useful, and pretty good at what they do. In the last few years, I’m struggling more and more to with engagements we do, because EDRs just get in the way and catch a lot of what would pass undetected a month ago. Staying on top of them with our tooling is getting more and more difficult, and I would call that a good thing.

    I’ve recently tested a company without EDR, and boy was it a treat. Not defending Crowdstrike, to call that a major fuckup is great understatement, but calling it “corporate spyware garbage” feels a little bit unfair - EDRs do make a difference, and this wasn’t an issue with their product in itself, but with irresponsibility of their patch management.


  • It has been a while since I have to deal with problem complexities in college, is there even class of problems that would require something like this, or is there a proven upper limit/can this be simplified? I don’t think I’ve ever seen O(n!^k) class of problems.

    Hmm, iirc non-deterministic turing machines should be able to solve most problems, but I’m not sure we ever talked about problems that are not NP. Are there such problems? And how is the problem class even called?

    Oh, right, you also have EXP and NEXP. But that’s the highest class on wiki, and I can’t find if it’s proven that it’s enough for all problems. Is there a FACT and NFACT class?


  • Here is a picture, that may help a little bit. The n is input size, and f(n) is how long does the algorithm runs (i.e how many instructions) it takes to calculate it for input for size n, i.e for finding smallest element in an array, n would be the number of elements in the array. g(n) is then the function you have in O, so if you have O(n^2) algorithm, the g(n) = n^2

    Basically, you are looking for how quickly it grows for extreme values of N, while also disregarding constants. The graph representation probably isn’t too useful for figuring the O value, but it can help a little bit with understanding it - you want to find a O function where from one point onward (n0), the f(n) is under the O function all the way into infinity.
