Omg omg omg omg omg, it works again!!! :D Ugly hack that fixed everything: if FPGA_AUTO_USB: bus = os.listdir("/dev/bus/usb")[0] device = os.listdir(f"/dev/bus/usb/{bus}")[0] flash_command += ["--busdev-num", f"{bus}:{device}"]

I should stop getting (silently and jokingly) upset at people for saying "kilo" when meaning "kilogram" given that I frequently use "millis" to mean "milliseconds" and "nanos" to mean "nanoseconds" 😅

Wild, the first result when googling my name (with quotes) is now arXiv. But I'm genuinely happy that this paper is available for free now. It'd have been really sad to see it behind a paywall.

felt very cute~
Photo of this sheepy (most of the face censored with a 🐏 emoji) wearing pink and white cat ears. Its hair is a bit messy.
It is wearing a dark blue jacket and orange backpack straps as well as the green strap of a shoulder bag is visible.
In the background there's a blurry grass field with some hard to recognize animals grazing on it.

I really need to give Java a try again one day (I still use it once in a while, but mainly for BigInteger and usually just in jshell or for small scripts rather than as a true project)

and Streams omggggg I know they're old, but they were sooooooo nice to work with Sure, I can kinda do that in C++ to now, but I still feel like it was a lot easier in Java

After finally managing to create a Flatpak for an application of mine (I'll make another post about it), here's some complaints about Flatpak and Flatpak builder I need to let you. I'll be comparing to Snap a lot, because I have a bit of experience packaging Snaps. - it seems like there's no s[...]
