On looking at my code that does file reads, and steveklabnik's suggestion - Vec<u8> makes reasonable sense. At least that way, if you want nice encodings you've got the same problem agnostic of where the "string" c

Forgiveness also requires our being right . That's not a given. If not, it's not an apology, it's shouting at someone until they're too exhausted to defend themselves any more. So, we should start by not assuming that.

In a pinch my guitar amplifier will do (I don't mean after some soldering, either). AM radios are comically, wonderfully easy to build. Easy to build by accident, in fact. In retrospect I've no idea how practical physics labs ar

It does seem surprising (and I was all ready to slate rust until I remembered to build for release). If you care that much - naive FORTRAN iteration on the same machine, same compiler, took 1200 s. (I am, obviously, taking inspiration from

Oh no, simpler than that even. The FORTRAN solution was also using somebody else's algorithm (matmul), which is intrinsic, and, I believe, not multithreaded. I'm not employed to develop matrix multiplication algorithms, but it

Modern fortran is surpisingly pleasant to write. The last time optimisation came up, I tried the author's problem - multiplying two 4096x4096 matrices - in numpy, FORTRAN and Rust, on a standard laptop. Supposedly it took 9 hours in na

"invisible" syntax is precisely want I don't want. That's practically the definition of a bug! I know I set myself up for the last line. I can only say I've really made a good faith effort to try to understand the e
