Maintenance begins at creation, so why are we not creating better?
by @beet_keeperThe beats are the same. You work for government, or academia (lets face it, that’s probably where 90% of the work is) you have a deliverable; you save it; you print to PDF; you store it on an institutional repository with some metadata (or Zenodo, OSF or equivalent) and its done.
There’s a small chance that it’s FAIR (Findable, Accessible, Interoperable, Reusable) right? It has metadata that can be discovered by an audience looking for it and can be indexed by search engines. The data is potentially accessible if published correctly. They’re not particularly interoperable or easily converted, and PDFs aren’t really designed for reuse, even if tools like Apache Tika help ease the burden of extracting artifacts. It’s just a PDF, why are we even talking about FAIR? There begins a story…
The beats are the same, yet, we work in digital preservation, our backgrounds are in GLAM or software, why do we want to shoot ourselves in the foot? Why are we not using our skills to create better?

Hot take on digital sovereignty of #fileformats #digipres "A license tells you who owns the software, while the format tells you who owns the data", "Digital sovereignty is not achieved by changing who hosts the software, but by changing the format in which data is encoded." https://blog.documentfoundation.org/blog/2026/04/02/document-formats-a-mystery-to-many/

Do you think custom text file formats are a good idea? or should we just always use JSON/YAML/TOML?

✨Bringing light to #FileFormats ✨
Tough on the outside with food for thought inside!
File formats reveal a lot about the different meanings of an object.
CPP-008 and CPP-010 help you uncover them through #FileFormatIdentification and #FileFormatValidation:

Sure, we've all seen Mark YAML and even JSON Statham, but have y'all met TOML Holland yet?

Ah, the "Binary Formats Gallery"—because what the world really needed was a #museum for file formats, complete with GraphViz diagrams and hex dump visualizers! 🤓🖥️ I mean, who doesn't want to spend their Sunday afternoon compiling Kaitai Struct libraries just to admire the metadata of a Quake 2 model? 🌟🔍

Revisiting bsdiff as a tool for digital preservation
by @beet_keeperI introduced bsdiff in a blog in 2014. bsdiff compares the differences between two files, e.g. broken_file_a and corrected_file_b and creates a patch that can be applied to broken_file_a to generate a byte-for-byte match for corrected_file_b.
On the face of it, in an archive, we probably only care about corrected_file_2 and so why would we care about a technology that patches a broken file?
In all of the use-cases we can imagine the primary reasons are cost savings and removing redundancy in file storage or transmission of digital information. In one very special case we can record the difference between broken_file_a and corrected_file_b and give users a totally objective method of recreating corrected_file_b from broken_file_a providing 100% verifiable proof of the migration pathway taken between the two files.

They really fucked up with the new #fileformats. Why even call it #webp. Just put the #png extension on it and no one would have to know if you made it backward compatible, your moronic apes. Just put #jpeg at the end of #jxl files.
Dumbass engineers they should hire me. I could have told them this.

Ah, #SQLite, the digital hipster's favorite minimalist coffee shop disguised as a database engine ☕📚. Who knew file formats could be romanticized with so much technical jargon that even the table of contents needs its own table of contents? 😜✨ Just remember, if it's small, fast, AND reliable, you're probably dreaming—or reading SQLite's wishful documentation. 🚀

I have three .avi files that have identical size but different md5sum.
A simple binary diff tells me that there are a couple of single-byte differences. Is there some kind of tool that would allow me to tell what those differences amount to? (Video, audio, whatever else?)
EDIT: SOLVED, see below

The @w3c recently released version 3 of the #PNG spec more than 2 decades after version 2 was released in 2003. The new spec largely makes official various extensions already in use like animated PNGs, HDR support, and EXIF metadata, so many browsers and graphics apps already largely support it.
Here’s an article by Chris Blume, who is the chair of the W3C PNG Working Group: https://www.programmax.net/articles/png-is-back/

How-To Geek: Snipping Tool Is Getting a Big GIF Upgrade. “GIFs remain one of the most popular image formats on the internet, despite their age. They’re even natively integrated into most messaging apps. Now, Microsoft is testing the ability to create and export them using Windows’s native screenshot and screen recording tool.”
