I do systems programming professionally, there are many reasons that Go is unsuitable for systems programming but all of them come down to having very little control over the resultant assembly that your program generates and very little po

The main reason the way I see it is that a lot of people who still use C and C++ need maximum speed, and D is only memory-safe with its garbage collector enabled. This affects latency and adds overhead. For many cases using a garbage collec

Loop unrolling is useful only when it enables other optimisations. The most common is constant folding.

C is a very difficult-to-parse language for both humans and computers and its syntax family got popular as much from circumstance as anything else. JavaScript stole Java syntax to court Jaca developers, Java stole C++ syntax to court C++ pr

The “less harmful alternatives” are simpler only in a surface-level way. Go is “simpler” than Python in that the language has less features, but that leads to more complex code since there is less possibility to abstract things away. It is

Any restrictions you put on what is and isn’t art will be contradicted by something, somewhere. A large number of pieces of art exist only to raise the question of what art even is.

I don't know about the others (reportedly Cling for C++ is good) but the Rust repl doesn't work properly and is basically just a frontend for incrementally writing a Rust file.

Yes, because you get told about problems at compile-time rather than at runtime.

For completeness, to scale relative complement up to N lists you would need to repeat the last list 2^N times. So it'd look something like: rel_com() { for i in $(seq 1 $#); do for j in $(seq 1 $(bc <<&l

If you use Rust's equivalent of `-march=native` you get faster code that can target modern hardware. We would have to get another factor-of-two speedup for the maintainance burden of using inline assembly to be worthwhile. https:&#x2F

If you use `-C target-cpu=native` (Rust's equivalent of `-march=native`) you get code that uses `mulxq` in order to avoid `pushf`/`popf`. https://gist.github.com/Vurich/5cb83c773e90fc7a463ccb58e1dad...

It's possible that `pushfq`+`popfq` get turned into a `mov` from the flag register into a the output register due to microcode-level optimisations.

Great catch, you're absolutely right. LLVM is smarter than me once again.

They're certainly familiar with assembly itself, but the `asm!` macro and the related constructs in Clang/GCC is its own beast and has a lot of footguns (like GCC allocating registers as overlapping by default). I don't begru

Higher-precision arithmetic is important but is not our primary product. The existing code was performant enough for our usecase (although the increased speed is helpful). Rust has many benefits and I find it hard to imagine how anyone mana

C has had strong support for inline assembly for a long time, and in fact for a short period we called out to C in order to use inline assembly on stable (the function call overhead was worthwhile compared to how much faster the assembly im

I really like that you have to use `env` in fish, since it's cross-shell - it works in bash/zsh/dash/whatever. The `A=b foo` syntax is an unnecessary appendix in the syntax that complicates matters while only saving 4 ch

Ideally there would be a better way to choose locale on a per-site basis rather than having it be baked into each app individually. Many apps have no settings page, and those that do often require you to log in to change the settings. I hav
