  • It’s interesting that, with Python, the reference implementation is the implementation — yeah there’s Jython but really, Python means both the language and a particular interpreter.

    Many compiled languages aren’t this way at all — C compilers come from Intel, Microsoft, GNU, LLVM, among others. And even some scripting languages have this diversity — there are multiple JavaScript implementations, for example, and JS is…weird, yes, but afaik can be faster than Python in many cases.

    I don’t know what my point is exactly, but Python a) is sloooow, and b) doesn’t really have competition of interpreters. Which is interesting, at least, to me.
















  • It is “backwards” from some other commands — usually you run copy/rsync/link from source to destination, but with tar the destination (tarball) is specified before the source (directory/files).

    That, and the flags not needing dashes always just throws me for a loop.

    And the icing on the cake is that I don’t use tar for tarring that often, so I lose all muscle memory (untaring a tgz or tar.bz2 is frequent enough that I can usually get that right at least…).


  • You mentioned ham radio — definitely fun! It’s a process to get into it though, as you need to study/pass an exam, and then you need a radio. Radios range from cheap ($25 or so) in the VHF/UHF (“walkie talkie”-style) to more expensive for an HF rig ($1000 range for 100W HF). If you want to get into low power (“QRP”) it can be much cheaper. You also need a fair amount of space for a good antenna setup…

    There are tons of different communication modes, some without a computer and, like you mentioned, some that use computers. wsjtx and fldigi are popular programs.

    Good luck!




  • I’m curious what you’re doing on an SBC that explicitly requires x86, though?

    Not parent, but I used ARM SBCs for a bit, and while it was nice, my x86 experience with a nuc has been much, much better. HW acceleration works on some RPIs, and sort of worked on my Orange Pi 5+, but only when using an ancient kernel which had some hacks (like, kernel debug messages saying “DISABLE THIS FOR RELEASE!”). And afaik RPI 5 doesn’t support hw encoding (not to mention no SSD support).

    Basically, my experience was that the hardware was neat if sometimes limited, the energy consumption was great, but the software/kernel support…ugh. YMMV of course.
