Just some light Sunday afternoon entertainment: Printing from NetBSD on the dotmatrix printer by dumping data to /dev/ulpt0. The netbook doesn’t have a parallel port, so this must be done over USB. NetBSD.escp was created by a little custom ESC/P converter written in C. 🥳

Video description:

Video begins with a view of the netbook’s screen: 3 windows are open, one of them showing the typical NetBSD logo to print, the other one shows the commands I ran in preparation:

magick /usr/X11R7/include/X11/pixmaps/NetBSD.xpm -depth 8 -alpha set /tmp/NetBSD.pam
./pam2escp /tmp/NetBSD.pam /tmp/NetBSD.escp

The other terminal shows a root shell with this command:

cat /tmp/NetBSD.escp >/dev/ulpt0

I hit Enter, the printer starts printing.

Camera pans to show the printer, an Oki ML 3390. Continuous paper. Once finished, I manually feed the paper a little bit to better show the result.

(If you turn up the volume enough, you can hear “Leaving” by “Chill Carrier” from 2008.)

@athanasia@twtxt.net The main problem is that I don’t front mbox.blue with my Edge infra that I front the rest of my infra with. So mbox.blue is kind of independent if that makes sense. It has nothing in front of it to protect anything. So I would just put a simple Caddy PoW at it’s reverse proxy and call it a day if that works for you? – I think I’ll make this per-box/per-user configurable too?

Also apologies. If you want to chat to me in more ~realtime, I’m more active on something we’re calling Parley – A truly decentralised federated IRC chat system. You have to spin up your own instance (ideally) or join someone else’s, but otherwise you use a normal IRCv3 capable client, but the entire “network” (so to speak) automatically forms a decentralized mesh.

@athanasia@twtxt.net I actally have my own PoW that I can put in front of mbox.blue if you like. It works very similarly to Anubis. I do have to warn you however, I don’t really think these PoW techniques are very effective IMO. Also re Guestbook message, sure, one sec…
