What does he actually mean by this? I've dabbled in C's specification and weird behaviour on multiple occasions but I have no clue what he is referring to.

zstd can't really be attributed to Facebook. Yann Collet started work on it before joining Facebook, so it was kind of imported. I am sure it made developing and standardizing the algorithm easier, but what makes it such a good (perfor

I misunderstood the question then, since I thought it was about learning about the newer language features. C coding standards differ quite a lot, and unfortunately I can't point out any software that has standards developed for safety

> Basically I always read in HN/lobsters/other forums that modern C is just as safe as newer languages This is absolutely false. Modern C++ might get close (although I am not too familiar with it) but C has not gotten much safe

PNG is fully serial, no? So 7000x seems like a big over exaggeration

I'd assume memory usage as well, because it has a tiny context window compared to zstd

QOI is an image codex, lossless, and not parallelizable. I don't think they are comparable

Even worse: bit fields can only be applied to int, signed int and unsigned int (maybe char as well but i dont remember) Even crazier is the fact that an int bitfield's signedness is implementation defined

You mean the algorithm used in hook[0]? These are not really top performers anymore. PPM has generally performed better and nowadays it's LLMs and context mixers that are at the top of text compression[1] [0]: https://mattma

Why not use real world data instead? Grab a large pdf or archive and use that as the benchmark.

huh, that was probably the least infuriating filter I have encountered in a while. It's frustrating how just changing a filtering option will reload the entire web page on most websites.

Let me bring you a third (not necessarily true) interpretation: The developer who has experience using cursor saw a productivity increase not because he became better at using cursor, but because he became worse at not using it.

It's funny how they say they are at 10% of the code of LLVM in their marketing, when it is actually closer to 0.1%. Throwing LLVM version 20.1 through wc (just the subdirectory llvm/lib) results in 2.3 million lines for all .c and

That is extremely unethical. Going off Wikipedia, most people with Huntington's start presenting symptoms from 30 to 50 years of age. Those are 30 years that they can live a normal fulfilling life. Prohibiting people from having kids b

Or homework is seen as a way for students to engage with the materials they are being learning about. Having an AI spoon-feed them the answers is not that different from students not doing the homework and failing the exams.

Kakoune has been my main editor for the past year (give or take) and uses an array of lines [0]. Ironically, multi-cursor and regex are some of the main features that made it attractive to me. I just tested it out on the 100MB enwik8 file I

I think KKrieger required pretty beefy specs for the time. It's a different kind of optimization they were aiming for (code size Vs execution speed) Although a friend of mine ran it on an integrated intel GPU recently and it performed

What is wrong with versioning a language like c89, c99 etc.? I think it is a lot easier to keep track of the 7 versions of C than the 14 that are available for zig and the however many there are for rust. I do agree that some of the UB is a

I agree, but for a blog post it is more concise (IS_CONST or anything that is long would take up a lot more screen real estate on my phone).
