Perhaps notable: years ago the original original chardet was rewritten with a different license: https://github.com/hsivonen/chardetng AFAIK this was not a clean room reimplementat…

Looks like the command is still called tldr at least, only the package/repo has a different name.

That comment is saying to use C++, not to add destructors to C.

I've worked on a system where ULIDs (not UUIDv7, but similar) were used with a cursor to fetch data in chronological order and then—surprise!—one day records had to be backdated, m…

The current amount of typechecking might be a net efficiency improvement AFAIK. It provides a hard runtime guarantee that variables are certain types while Python has to check whet…

Python managed to do this by not actually checking the types at runtime. If you declare a list[int] return type but you return a list[string] then nothing happens, you're expected …

I don't think this shows deep thought on his part. By Stallman's own telling a free Objective-C frontend was an unexpected outcome. Until it came up in practice he thought a propri…

I think you're getting fooled: >>> from io import StringIO >>> for line in StringIO("foo\x85bar\vquux\u2028zoot"): print(repr(line)) ... 'foo\x85bar\x0bquux\u2028zoot'

rustc is only loosely tied to LLVM. Other code generation backends exist in various states of production-readiness. There are also two other compilers, mrustc and GCC-rs. mrustc is…

RFC 3629 says surrogate codepoints are not valid in UTF-8. So if you're decoding/validating UTF-8 it's just another kind of invalid byte sequence like a 0xFF byte or an overlong en…

The big problem isn't invalid UTF-8 but invalid UTF-16 (on Windows et al). AIUI Go had nasty bugs around this ( https://github.com/golang/go/issues/59971 ) until it recently adopte…

Rust has the clap_complete package for its most popular arg parsing library: https://crates.io/crates/clap_complete ripgrep exposes its (bespoke) shell completion and man page gene…

See also: https://internals.rust-lang.org/t/can-the-standard-library-s... A file descriptor can't be -1 but it's not 100% clear whether POSIX bans other negative numbers. So Rust's…

It means that anything strange that happens next isn't a language bug. Whether something is a bug or not is sometimes hard to pin down because there's no formal spec. Most of the t…

I can think of a lot of cases where it theoretically could be a problem, but `cut -d=` is the only one I've found so far where an end user ran into trouble because of this ambiguit…

The problem is existing shell scripts and muscle memory and command histories. `cut -d=` has always worked and works on all the other implementations so it should keep working if y…

I researched this for my own argument parser ( https://github.com/blyxxyz/lexopt/issues/13 ) and concluded that it's a minor issue. This syntax is supported by argparse and clap, t…

Anders Hejlsberg explains here: https://youtu.be/10qowKUW82U?t=1154 . TL;DW: - C# is bytecode-first, Go targets native code. While C# does have AOT capabilities nowadays this is no…

According to the blog post ( https://fishshell.com/blog/rustport/#fn:formatting ): > A lot of the increase in line count can be explained by rustfmt’s formatting, as it likes to sp…

Agreed that societies can get sophisticated without writing, but Egypt was already considered mind-blowingly old in Plato's time. The start of the Timaeus features an eight thousan…

That's a wrapper around the actual implementation (which lives in an external package). Notice "use hashbrown::hash_map as base;" at the top. There's far more unsafe there: https:/…

C-c M-g l gets you there. (C-c M-g leads to a submenu that also has blame.) Until this thread I didn't know it could also do regions.
