luna, friend of eggbug
luna@pony.social
so i'm reverse engineering the ipod's photo database file, right (y'know how on the old ipods you could sync photos to them if they had a color screen, and then you could browse your albums on the ipod? the internal database it creates for that)
as i've been building a parser for it, i've been nominally parsing things i don't understand yet into u32 fields until i can reason otherwise
anyway, as i'm poring over the parsed data, i see some interesting neighboring values, exactly four u32s, which i don't quite understand and which aren't documented (at least not in the docs on the iPodLinux wiki; they're incomplete and very outdated but they've still been an invaluable starting point)
for some of the photos (and for all album art in the artworkdb, which uses the same database format) these four u32 fields have constant values (i.e. matching between photos) but for other photos they look almost entirely random. perhaps they're hashes or randomized identifiers? but even for the random-looking ones they're kinda similar between photos
and then i think.. are they four floats maybe?
i plug the raw hex values into https://float.exposed (excellent website, highly recommend) but i'm not entirely convinced by the numbers i see
hmm.
the ones with constant values repeat on an 8-byte period, so maybe it's a pair of doubles?
so i tweak my parser to try reading them as such, re-run it, and am immediately filled with a horrible sense of dread as i recognize exactly what the numbers are.

Katharsisdrill
katharsisdrill@hub.volse.noAllerede sidste år ville jeg have gået i gang med at lave en Kickstarter med følgende mål:
At lave en forening der kunne tage sig af server og software og hvis medlemmer skulle være foreninger op til 1000 mennesker (arbitrært tal). På den måde ville den store forening stille teknisk support, drift og deslige til rådighed og foreningerne kunne så bestå af folk uden teknisk kunnen. Disse foreninger ville til gengæld sagtens kunne moderere, indkræve kontingent, holde generalforsamlinger og den slags som vi alle kender her i foreningsdanmark.
Min inspiration er mit lokale coop-bredbåndsnet, Parknet.dk, der har andelsforeninger som medlemmer og som, da det ikke er et profitforetagende, giver os billigt internet og TV.
Jeg har jo været på Fediverset i 12 år og har altid synes at alle skulle være her og ikke på Twitter, Facebook, Insta og TikTok. Lige nu føler jeg et stort ansvar for at organisere et eller andet.
Tiden er måske også der hvor den store mainstream kan se hvad det drejer sig om, og pressen vil måske også være mere interesseret nu hvor alle kan se hvad Zuckerberg og de andre egentlig er.
Jeg havde tænkt mig at gøre det alene (som sædvanligt), men det giver jo ingen mening. Er der nogen der kunne tænkes at ville være med, eller bare diskutere hvordan det kunne gøres.
Måske hvis I gider dele det her, så folk kan se det.

bsdphk@fosstodon.orgThis is, hands down, the most useless piece of FOSS I have ever released.
It preserves the unique Rational R1000/s400 computer and it's Rational Environment in software for future generations:

I can finally reveal some research I've been involved with over the past year or so.
We (@redford, @mrtick and I) have reverse engineered the PLC code of NEWAG Impuls EMUs. These trains were locking up for arbitrary reasons after being serviced at third-party workshops. The manufacturer argued that this was because of malpractice by these workshops, and that they should be serviced by them instead of third parti
es.
