"One form of public speaking not usually recognized as such is teaching. I've had a few experiences in educational situations and they've been worse than flies crawling over my face...

You can't pay teachers enough to do what they do. Having been in their shoes, even briefly, has converted me into an education advocate. Double all teaching salaries now." - Douglas Coupland

What will you bitflip today?


by @beet_keeper

I want to let you into a secret: I enjoy corruption. Corrupting digital objects leads to undefined behavior (C++’s definition is fun). And flipping bits in objects can tell us something both about the fragility, and robustness of our digital files and the applications that work with them.

I had a pull-request for bitflip accepted the other day. Bitflip is by Antoine Grondin and is a simple utility for flipping bits in digital files. I wrote in my COPTR entry for it that it reminds me of shotGun by Manfred Thaller. The utility is exceptionally easy to use (and of course update and maintain written in Golang) and has some nice features for flipping individual bits or a uniform percentage of bits across a digital file.

My pull-request was a simple one updating Goreleaser and its GitHub workflow to provide binaries for Windows and FreeBSD. I only needed to use Windows for a short amount of time thankfully, but it’s an environment I believe is prevalent for a lot of digital preservationists in corporate IT environments.

Bitflip is a useful utility to improve your testing of digital preservation systems, or simply for outreach, but let’s have a quick look at it in action.

Wait, isn't there something like a summer break for this guy ever?!

Nope. 'cuz summer
🌞 time is…
Radio Irrtum! SPECIAL time!

↓↓↓ German version far below the English one ↓↓↓

Precisely said, the next issue of
#RadioIrrtum! will be on air this Saturday, 2024/07/06, 8:00pm UTC+2/Berlin time, sharp. Over at Alex Berlin FM at 91MHz and DAB+ K7D around Berlin and worldwide at https://www.alex-berlin.de/radio/15-live-auf-91.0 .

#Radio Irrtum! is a German language #radioShow exploring the sonic vastness of the #underground to raise your attention for new unheard #music. So it's fine to ignore that German language aspect - 'cuz it's all about the music!

And this time there is a Special rolling in! The…

Chiptune PuNk Special!!

Up to date helluva
#phunky #demoscene #chiptunes running on old rusty #homeComputers from the 80s like the #zxSpectrum, #C16/#Plus4, #AtariST, #C64 and of course the #Amiga.
No additional effects, no extra synths, no added drums. Just pure chippy bless!

Music full of
#bitrot sample aliasing & strange chirps on brutally tackled chips like the #TED, #YM2149, #SID, and of course #Paula. No worries, I'll explain it all (however in German – as my station demands it).

With super cool music hackers like…

-
@ne7@icosahedron.website
- Shiru
-
@h0ffman@mas.to
- STU (didn't know him when I produced this show 4 weeks ago – just found his music excellent. However this weekend I was performing next to him on stage in La Chaux-de-Fonds (not kidding - life is sometimes full of surprises) - AND WHAT A SET HE DID, LIVE on his 2 original Atari STs!!)
- LMan
- Jammer
-
@bacalao@v.basspistol.org
- Groo
- Xale or
- Psych858o

I've always wanted to produce THIS FEATURE and now it's right there, already uploaded to the station and ready 2 hit the aether. I'm totally happy how it came out and can't wait to have it in public. That is why I'll attach my in depth explanation trailer instead of just the animated Radio Irrtum! logo. This one:
https://video.ploud.fr/w/iDTikV3q7y5YqeY2LBdLwn

I'll post playlist + manuscript later here (provided I’m home, else it will come up the day after). And if you have questions? I'll gladly answer! Just ask!

CU all on Saturday! :)

Weekend #bitrot fun: Just discovered that Mac OS 12 Monterey no longer reads HFS disks. Was checking on some backups from late 90s on burned discs and disk images and was relived to find they still work fine on 10.13 High Sierra on an Intel Mac Mini I kept around. Kind of wish I still had a PPC machine that could boot Mac OS 9, but was able to get it going under emulation with #SheepShaver and it’s a trip to see Photoshop 3.0 on a window in my current Macbook.

@BinGanzBrav SSDs solltest du alle 6 Monate mit Strom verbinden.
Bei HDDs schaut es schwieriger aus. Da gibt es #BitRot. Das bedeutet, dass sich die Platte nach einigen Monaten oder Jahren partiell entmagnetisiert und deswegen nicht mehr alle Dateien korrekt gelesen werden können. Als Schutz kannst du regelmäßig die Dateien neu auf die HDD schreiben oder du nutzt Software die einen sogenannten „Scrub“ unterstützt.
