You don't actually seem to be addressing the quoted text... but I can reply to your arguments. Sure, it would be ideal if there were a new book on C which did a better job of explaining some of the developments since K&R 2ed was wr

I don't agree that it's a good practice, I'm simply quoting one example to you since you mentioned you were not aware of any. IIRC, you can find many GitHub issue threads on the Cython repo where they go into more detail. It

It's unwise to neglect it in the long run. It's perfectly reasonable to ignore it initially. There are different valid pedagogical approaches here. Your approach may be suitable for the type of student you were interacting with, b

Here's one example of when to commit auto-generated code: if you use a tool like Cython and want to distribute sources to an end user, it is frequently recommended to distribute the C sources generated by Cython instead of the Cython c

All of this is true, but if you are just starting with C, none of it matters. If you continue using C, then you should eventually learn this stuff, but to overburden someone with a list of 100 things they must do right is the surest way to

My comment is for the OP, not for you. Go nuts learning C tooling and have fun.

Unfortunately, global hidden state is an unavoidable fact of programming. I don't see how one could be very good at programming if they were kept blissfully ignorant of it. Sometimes there is magic under there, and you just have to d

The suggested way to learn C in 2023 is the same as the suggested way to learn all languages for the past decade or so. Do you like videos? Find videos on YouTube and watch them. Do you like books? Go on Amazon and search for "C progra

If you're just beginning with C, it doesn't matter. If anything, it's better to be exposed to these unsafe practices and make mistakes with them in the very safe environment of your own home, where absolutely no one cares wha

Don't bother with this stuff (or with "modern C") if you're just beginning to learn the language. You don't need it for small programs. No one is going to yell at you if your first effort isn't perfect. And no

Reading 2k+ commits is a big waste of time. Forcing yourself to read every commit to a project you "like" in order contribute to it is putting the cart before the horse. Just because you "like" a project doesn't mea

I don't recommend learning how to use Autotools unless you need to work on a project that uses it (and even then, try to avoid it). Highly recommend learning CMake or Meson instead. If you're just getting started, there's no

Yes. It’s easy. Easier if you pack up your stuff yourself. And obviously the less stuff you have the easier it is. But of the tasks humans find themselves endeavoring away at, it ranks among the more straightforward.

The target audience of The Atlantic are rentiers in the US who don’t want to have to deal with the cognitive dissonance of charging unaffordable rents and contributing to misery in the world.

I used to commute an hour each way from Baltimore to DC on I-95. I am a very defensive driver. My experience had everything to do with other people driving aggressively. I have met countless people who have had the same problem. I guarantee

I live in New York City, I commute on the subway everyday, I do not make a high salary, and I do not live in an affluent area. If I drove to work instead of taking the subway, it would cost a full order of magnitude more per year, and my co

It computed the division correctly with almost three digits of accuracy. This isn't completely wrong. I don't personally know how ChatGPT goes about doing division of two integers, but I would be surprised if it had somehow how ma

You can speak for yourself, but you obviously haven't talked to enough people to make a sweeping claim like that. Maybe you like the vroom vroom, but there are loads of people who are forced to drive every day and who absolutely loat

Consider that in a "regular"-style school, there is no reason to expect the situation would be any better, although it might look the way you think it should. Possible differences: - the kids may not be "just walking around&q

I’m surprised you view Montessori education as some sinister thing despite your daughter doing well with it. I feel like you might be overthinking things. Leaving aside Montessori’s somewhat grandiose speech, it’s just a pedagogical mode wh

None of this is true or very important anymore. For aliasing, in C, there's the restrict keyword, although it isn't used that often. If you take a look at BLIS or even BLAS, restrict isn't used. C++ doesn't have restrict

I think this is an interesting question, and I'd be curious to know the answer, too. That said, I might push back on the idea that CG problems don't have this kind of regularity. They give the example of a point being either on a

The requirements for writing curl are different from the requirements for writing other software. Just because C89 is a good choice for curl doesn't mean that C99 isn't a better choice for other things. The failure isn't in h
