  • The hack is still not fully understood and is being analyzed. It doesn’t help that Github suspended everything, including the original maintainer’s account (who is believed to be a victim of social engineering).

    Anyway, you will eventually see a post mortem. I’m willing to bet that it’s going to be as phenomenal as the hack itself. The case and its investigation is going to be a classic case study for all security researchers and security-minded users. Anyway, I doubt that the attackers will ever be found. Jia Tan, Jigar Kumar and others are going to remain as ghosts like Satoshi Nakamoto.




  • Peter Thiel is insolent enough to say out loud what these companies practice - ‘competition is for losers’. These quasi-monopolies aren’t here to provide the best value - quite the opposite. They want to kill all competition by any dirty tactic and then use the diminished choice to wring the customers of every penny they have. They want to extract maximum revenue by making sure that their inferior solution is the only option customers have.

    This problem isn’t solvable by market regulation alone. The world has enough a*****es around who will climb to the top of successful companies and find ways around the regulations. They’re being as bad as they can, while skirting the limits of what’s illegal. My main gripe is with the engineers, programmers, technicians and all technical creators who enable these scumbags. It’s not hard to see that supporting a proprietary solution amounts to yielding the consumers’ bargaining power to a monopoly. Despite that, they keep making these choices. For example, it’s not uncommon to hear senior engineering managers or technical-lead level employees saying, “I know that Chrome is spyware and I want to quit it. But this <stupid-webservice-at-office> works only on Chrome”. I feel like screaming at them that if they’re too incompetent to demand a change at the level they’re at, they’re in the wrong profession.

    If you’re a technical creator, your choices matter. It affects a lot more people than you alone. But more often than not, I see such creators surrendering principles in exchange for convenience. They hold as much responsibility as the market-abusers in making the world the way it is now.



  • CUDA is an API to run high performance compute code on Nvidia GPUs. CUDA is proprietary. So CUDA programs run only on Nvidia GPUs. Open alternatives like vulkan compute and opencl aren’t as popular as CUDA.

    Translation layers are interface software that allow CUDA programs to run on non-Nvidia GPUs. But creating such layers require a bit of reverse engineering of CUDA programs. But they are prohibiting this now. They want to ensure that all the CUDA programs in the world are limited to using Nvidia GPUs alone - classic vendor lock-in by using EULA.



  • I find myself passing copies of values around and things like that, it might be that the compiler just takes care of that,

    Rust prefers explicitness over magic. So it does what you tell it and doesn’t just take care of that.

    If you’re copying a lot of values around (I.e cloning. Not moving or borrowing), then you’re definitely doing it inefficiently. But you don’t have to worry too much about that. If there are too many difficulties in borrowing, it may be because those borrows are problematic with respect to memory safety. In such cases, sacrificing performance through cloning may be an acceptable compromise to preserve memory safety. In the end, you end up with the right balance of performance (through borrowing) and safety (through cloning). That balance is hard to achieve in C/C++ (lacking in safety) or in GC languages (lacking in performance).

    If that’s the friction you’re facing in Rust, then I would say that you’re already in a good position and you’re just trying too hard.


  • they don’t feel like your fighting the language

    I really understand what you mean wrt Rust. I really do - I was there once. But it’s a phase you grow out of. Not just that - the parts you fight now will eventually become your ally.

    and let me feel sort of creative in the way I do things

    I had the same experience with C/C++. But as the design grows, you start hitting memory-safety bugs that are difficult to avoid while coding - even after you learn how those bugs arise in the first place. Just a lapse of concentration is enough to introduce such a bug (leaks, use-after-free, deadlocks, races, etc). I’ve heard that C++ got a bit better after the introduction of smart pointers and other safety features. But, it comes nowhere near the peace of mind you get with garbage collected languages.

    That’s where Rust’s borrow checker and other safety measures kick in. The friction disappears when you acquire system knowledge - concepts of stack, heap, data segment, aliasing, ownership, mutation, etc. These knowledge are essential for C/C++ too. But the difference here is that Rust will actually tell you if you made a mistake. You don’t get that with C/C++. The ultimate result is that when a Rust program compiles successfully, it almost always works as you expect it to (barring logical errors). You spend significantly less time debugging or worrying about your program misbehaving at runtime.

    The ‘friction’ in Rust also helps in another way. Sometimes, you genuinely need to find a way out when the compiler complains. That happens when the language is too restrictive and incapable of doing what you need. You use things like unsafe, Rc and Refcell for that. However, most of the time, you can work around the problem that the compiler is indicating. In my experience, such ‘workarounds’ are actually redesigns or refactors that improve the structure of your code. I find myself designing the code best when I’m using Rust.


  • but I disagree wholly that it’s the language’s fault that people can exploit their programs. I’d say it’s experience by the programmer that is at fault, and that’s due to this bootcamp nature of learning programming.

    Considering that even the best programmers in the world can’t write correct programs with C/C++, it’s wrong to absolve those languages of the massive level of memory safety bugs in them. The aforementioned best programmers don’t lack the knowledge needed to write correct programs. But programmers are just humans and they make or miss serious bugs that they never intended. Having the computing power to catch such bugs and then not using it is the real mistake here. In fact, I would go one step further and say that it isn’t the language’s fault either. Such computing power didn’t exist when these languages were conceived. Now that it does, the fault lies entirely with the crowd that still insist that there’s nothing wrong with these old languages and that these new languages are a fad.
