I want to share a little idea for a new extension with the goal of adding direct messages in #twtxt https://github.com/tanrax/twtxt-direct-message-extension

another one would be to allow changing public keys over time (as it may be a good practice [0]). A syntax like the following could help to know what public key you used to encrypt the message, and which private key the client should use to decrypt it:
!<nick url> <encrypted_message> <public_key_hash_7_chars>
Also I’d remove support for storing the message as hex, only allowing base64 (more compact, aiming for a minimalistic spec, etc.)

just spent like half an hour finding a terminal based color picker that would just. turn the cursor into a cross hair and let me pick from the screen. in linux fashion this was somehow difficult

@kat@yarn.girlonthemoon.xyz i wound up with xcolor AND pastel at the same time, because xcolor does exactly what i want while pastel and its picker subcommand does the same thing, relying on xcolor, but brings up a nice graphic of the picked color and related colors, plus more than just the hex code. neat.
For some reason, I was using calc all this time. I mean, it’s good, but I need to do base conversions (dec, hex, bin) very often and you have to type base(2) or base(16) in calc to do that. That’s exhausting after a while.
So I now replaced calc with a little Python script which always prints the results in dec/hex/bin, grouped in bytes (if the result is an integer). That’s what I need. It’s basically just a loop around Python’s exec().

Oh boy, I’m looking for trapezoidal (like ACME thread) screws and nuts in left hand form. The rods are already expensive, but nuts feel like a total ripoff. A hex nut for Tr20x2 being 30mm long and 30mm in “diameter” costs me 22 bucks! O_o Just a single one, made of regular steel. A meter of rod is 21€. The more common Tr20x4 hex nut is just 7€ and the rod 17€, but 4mm pitch is a bit much for a leadscrew for semi-precision work I reckon.
Well, maybe I just use metric threads. I will sleep on this.
I learned a #Toronto #hex club just started! I’ve played since ‘98 or ‘99, but rarely in person. https://www.hexwiki.net/index.php/Hex_clubs
I’d love to read the original source code of this:
https://ecsoft2.org/t-tiny-editor
This was our standard editor back in the day, not an “emergency tool”. And it’s only 9kB in size … which feels absurd in 2023. 😅 The entire hex dump fits on one of today’s screens.
Being so small meant it had no config file. Instead, it came with TKEY.EXE, a little tool to binary-patch T.EXE to your likings.
