It's always a tradeoff, but I'm surprised to see so many people say that just because Python isn't fast it shouldn't get multithreading. Yes, by using Python we leave a lot of performance on the table. We also get a lot

But thread-unsafe code is not the same as incompatible code. That's the point. You can just choose to say "NOT THREAD SAFE" (just as many C libraries aren't thread safe and need to be wrapped in locks to be used by multi

You're missing something, which is that a lot of libraries will be "i-don't-care-about-gil". Only native extensions need to choose GIL or noGIL due to the ABI difference, but pure Python libraries should run with the sam

by gjulianm 3y ago
Which code is automatically going to run in threads? As you say, basically nobody uses Python threads. So even enabling no-gil, nothing is going to change because sequential code will still be sequential.

I'm one of those happy to see the GIL removed. I've had troubles with the 2->3 transition and more recently with the 3.6 EOL, which wasn't as traumatic but still a little bit troublesome. Despite that, I prefer another tra

I think there are several reasons: - The history is backwards: it isn’t that devs wanted to make a native library and then chose Python, it’s that they chose Python and then they needed a native library. - Python works very well for scripts

Well, sugar needs an intermediate step to cause cancer, obesity, which is something that can be controlled. Not to mention that quite a lot of foods have sugar in them and you can't really take it out. On the other hand, red meat and b

Not really, and the link between red meat and colon cancer is very well established and significant, much more than the alternatives.

by gjulianm 3y ago
I can't really trust the nutritional advice of someone that deliberately loads up on things like bacon and red meat, which are known risk factors for colon cancer.

I haven't used Cython too much, it does look really interesting but the translation layer worries me a little bit for more complex modules. However, I've been using pybind11 extensively and it's a delight. Well designed, docu

I think that at this point this is a discussion about semantics, just as this other commenter pointed out: https://news.ycombinator.com/item?id=36758407 Yes, you can do something in C that somewhat resembles encapsulation.

LTO isn’t always going to inline things you want it to inline, that’s the main issue I have with it.

Out of curiosity, how would you do it? The ways I've seen require using another "public" struct and either casting public to private or using a nested pointer, each with their set of problems. In either case, it's still

As the other commenter said, and I want to reiterate, what led me to start with the talk about the private keyword is the big bold header that says "Myth: C has no equivalent to “private”" and the first code snippet that shows how

by gjulianm 3y ago
I mean, there's a big header that says "Myth: C has no equivalent to “private”" and a code example about the private keyword, so that's why I started saying that. Even then, my points still apply: this isn't really

by gjulianm 3y ago
The code sample still isn't equivalent. Now you have yet another pointer, which implies another allocation, another source of possible memory leaks and mistakes, and a separate memory space that will hurt the cache. > Those are impl
114.
by gjulianm 3y ago
Yes, that's usually how it goes, each header/source is like a "class". And usually, what you have is a "main" struct that represents the "class" itself. In this case that main struct can't have b

I wouldn't call this equivalent to the private keyword: * It does not work on a field, but on the whole struct. Either all fields are public or all are private. The latter case forces you to write getters/setters for properties yo

Precisely the point of most of those policies was to use rapid tests to ensure you weren't being infections at that moment or close to it. I honestly don't know what's so controversial about them.
