From a recent (December!) Ars Technica forum thread:
"I have been having this itch lately to get back into burning cd/dvds/bluray. It's like the early 2000s are calling me again. I want to burn 3d movies and blu ray and though I like streaming music, I have this fantasy of getting a wicked nice audio system and making my entire library cds again."

Just in time before the end of 2024, the Digital Dark Age Crew are back!
Always fashionably late, after 25 years they finally finished "Y2K", their legendary, previously unfinished track that addresses the threats of the year 2000 #Y2K problem.
Enjoy, and remember: tomorrow, we could all be living in the dark ages! #WheelOutTheDigitalDarkAgeKlaxon 📯

Just updated this 2021 post on #opensource #PDF processing tools, and added a section on the Arlington Model PDF Checker (IMO the Arlington Model is really where the future of PDF validation is at):

Interesting, both the German Federal Office for Information Security and the Swiss Coordination Office for the Permanent Archiving of Electronic Documents advise against the use of #JBIG2 compression in scanned #PDF documents.
This was prompted by the discovery in 2013 of the infamous "swapped characters" bug in Xerox photocopiers:

"Japanese digital dub legend Takafumi Noda aka Mystica Tribe meets up with Danny Wolfers Legowelt again for this unique concoction of digital dub with raw lo-fi synth wave.
Buckets of echo, crumbled tapes, mind altering phasers, luring spring reverbs, sloppy rhythm boxes, HEAVY INTENSE BASS and the ever mystifying melodica playing from Noda bring this project to a new level."

ICYMI - are "octal escape sequences" in #PDF strings really a preservation risk, as claimed by the authors of the recent "The Phantom 👻 of a PDF File" blog post?
Some quick tests I did with eight different PDF processing tools suggest they're not, and #JHOVE's inability to handle them really seems to be the exception here #wtfPDF #fileformatfriday

The authors of the recent "The Phantom of a PDF File" blog post argue that "octal escape sequences" in #PDF strings are a potential preservation risk.
But some quick tests with 8 different PDF tools suggest that #JHOVE is really the only tool that can't handle them!
Details in my new blog post "Escape from the phantom of the PDF" #wtfPDF 👻 :
