But can your PDF run an AI agent?

Well a font using a custom experimental shaping library. Your font can't do it normally.

In my opinion the question isn’t so much “if” but rather “when”. When will AI research and hardware capabilities reach a point that it’s practical to embed something like that into a regular document? We’ve already seen proof of concept LLMs embedded into OpenType fonts. I guess the other question is then “what capabilities would these AI agents have?” You’d hope just permission to present within that document. But t…
For Chrome's PDF renderer, the runtime is V8, so we're literally one (hilarious) line of code away from this glorious future existing today: https://pdfium.googlesource.com/pdfium/+/refs/heads/main/fpd... > // Use interpreted JS only to avoid RWX pages in our address space. Also, --jitless implies --no-expose-wasm, which reduce exposure since no PDF should contain web assembly. > return "--jitless";
You could write an LLM in plain JS, right?

#154I printed the PDF on A4 paper, but Tetris doesn't work! lol

That's why you run NoScript along side with UBO
I'm pretty sure noscript will break 90% of the webpages I visit. I just rawdog the internet. If Chrome gets 0day'd then a lot of us are going down - at least I'll have company.

#156Fortunately this does not work in Safari where the rendering is done natively.
I like how you used "fortunately". For me too the most important in PDF is to print a good and accurate text and graphics (preferably vector graphics), which recently is not as easy as it would be possible

#157playing Tetris on a pdf is the last thing I would have thought of. Kudos for the idea and implementation. To start a new game do I have to reload the pdf? Thanks

#158You glorious bastard, what a cool project! This is already a contender for most hacker project of the year :-) (below is not serious) I would advise people against using this in production though because it's still missing some critical features. For example: 1. The Javascript stops working when printed to physical paper. The resulting paper just has a static image and the controls no longer work. 2. It doesn't work…
> Javascript
Oh, so that's what it is. Bleh. Ok.
I thought it was cooler and made use of the fact that PostScript is a Turing-complete language to write Tetris in PostScript.
(I never really understood the PDF format but I always assumed it's some kind of compressed PostScript)

Love the demo video and post but for some reason this doesn't seem to work for me. Running Chrome on Android 14
Don't be sad, Google is planning to bring native Tetris support to Android.

Crazy. Looking forward shipping apps as .ttf instead of docker images.
