SPACE BALLS!

got the rotated text done yesterday. bah, it was difficult! and I don't even really know why. it's not a standard feature of #troff, so one has to inject some raw postscript in there. this should all be simple, but aww, there were some weird interactions. yet i made it, it works, so there.

also did the proof-reading on these latest parts, found a few small mistakes. i still need to do one (easier) table, and then i'm done with the first major part of the chapter, ca. 50 pages, 40%.

i think i'll actually print that out and try binding it into a booklet, as a trial.

Hey nerds šŸ˜Ž

I'm fundraising for my incredibly cool femme/queer electronics camp that's holding on by bloodied teeth this year. Find it in my bio.

BUT ALSO we take supplies. Specific stuff. We need:

-Wire cutters (not nippers!). We clean rust

-Nice-ish Raspberry Pis, mini computers, larger external hard drives and accessories. We teach about Kiwix, cyberdecks and more

-Meshtastic hardware

-Art PCBs (best by femmes/queers) for our pop-up museum

-Lockpick gun and practice padlocks

DM me.

so it cost anthropic $20k to find this openbsd crash bug which amounts to putting a negative integer in a tcp field where a negative integer was not expected by the c code which does some cavalier int cast bullshit, ie. a vuln which is totally fuzzable, and quite certainly would have been found by the fuzzers of the 2010s had anyone cared to burn that much compute on fuzzing openbsd.

The difference today is not that anybody suddenly cares about investing that much in openbsd (is the build server still a donated machine running in Theo's basement?), but that openbsd's reputation for security makes it really good marketing if you can find a bug, any bug, it doesn't matter; and that marketing value is what makes it worth spending $20k on fuzzing.

Does computer #history interest you, or maybe you're just curious where well-known and well-used tools come from? I've just updated the History of #Unix #Manpages, https://manpages.bsd.lv/history.html, with the content you didn't know you wanted til this very moment. Learn about how the "man" program came to be, and just why are manpages styled like that? It includes snippets from Cynthia "Cindy" Livingston, who wrote the manpage language "mdoc"; John Eaton, who wrote the first GPL man tool; Doug McIlroy, who helped to divide manpages into sections; and more. Did you know that serving manpages online was part of one of the original http daemons? Or that an xman existed before X11R6, in X10? Enjoy!
History of Unix Manpages

The Swedish computer club #PD68 built Motorola 6809 and 68k-based systems in the 80s. One of these systems, based on a 68k-based CPU board designed in Norway, runs the Idris OS, the first Unix clone.

I’ll give a talk on Idris and the PD68 machine next SATURDAY (April 11) – not! Friday as I wrote – at 19:00 at Update datafƶreningen in Uppsala. Iā€˜ll show the (non functional) PD68 machine and an Atari ST emulator running Idris!

[Edit: I'm okay on this for now, thanks!]

I have a handful of images in this style, but I only scans of physical media; the original files are lost or inaccessible. I’d like to have SVGs of these, but all the converters I’ve tried produce very poor results. Given the geometric style, it seems like it should be easy-ish to trace in Inkscape or whatnot.

Are there people I can pay to do this conversion? How do I find them, and what should I expect it to cost? Better yet: are *you* this person?

fiddly stuff: dual-page display/table.
missing column headings because i haven't made the macro for rotated text, yet.

some nice progress. i've made it into the instruction tables. they are full of quirky stuff, just look at those little devils...

took a bit to set up the macros for things, but after that it got pretty nice to work with. now of course i have about 12 pages more of this to type, and they have some new weirdness in them... *sigh*

Do you developer the softwares? Do you avoid "fashionable" glamour sites like github and PyPI? Do you avoid using other peoples code because "in the long term it will be better to learn how to do it myself"? Do you create packages on your kitchen table using saved giftwrap and found sealing wax? Do all your fave people hang out in an obscure corner of itch.io?

You are not alone and i have a new term for this: Goblin Mode Software Development
