This is funny. OpenAI, who scraped the entire internet to build its product, is now enforcing copyright via notices. They still don’t give credit for stealing content from everyone, yet now acting like holier-than-thou https://www.reddit.com/r/ChatGPT/comments/1cnvyzp/

new ISO PDF 2.0 extension has added glTF as a supported 3D format!

PDF therefore now supports four 3D formats:
U3D
PRC
SETP AP242

The project of one of the most expensive (and useless) infrastructures in Italy, the bridge that will connect Sicily to Italy, has faulty PDFs.

If you find yourself creating a new file format, please, oh, please do not allow junk before your magic (you do have a magic, right?!), within cavities or at the end of files. 🙏

Cursed TIL of the day: PDF is a vector image format, so you can convert a PDF to SVG with pdf2svg

Here's a fun AI story: a security researcher noticed that large companies' AI-authored source-code repeatedly referenced a nonexistent library (an AI "hallucination"), so he created a (defanged) malicious library with that name and uploaded it, and thousands of developers automatically downloaded and incorporated it as they compiled the code:

The presence of multiple images inside a #TIFF file can have unexpected consequences for digital preservation workflows. So how can we identify such files?

Some thoughts and suggestions in my latest blog post on multi-image TIFFs, subfiles and image file directories:

As always, feedback, suggestions and corrections are welcome!#wtfTIFF

I frequently have to deal with #PDF files that contain nested PDFs (which Adobe marketed as "PDF Portfolios").

They open fine in pdf.js in Firefox, but not in macOS Preview. They are just PDFs that have one page telling the user to download and use Adobe Acrobat (no way, fuck that), and then a bunch of attachments.

They're worse in every way than just distributing a zip/tarball of PDFs. Here's a 20 line Python script (with a nix-shell shebang) to unwrap 'em.

https://www.lullabot.com/articles/you-dont-have-pdf-problem-you-have-workflow-problem is a great reference. It's practical; I said "Yes!" so many times while reading it. And I chuckled much too. :) Please give this #a11y article a read and a share. Thanks Frances for writing it!

I am endlessly amused by the technical honesty of making PDF accessible by attaching an HTML page as a secondary tree.
