freedomben | on: Show HN: Tetris in a PDF
You 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 properly in Evince. It just shows an error "The document contains only empty pages"

-- this comment made my me laugh/choke on my coffee and I have no regrets.

I feel stupid for not getting the joke. It would have been nice if you explained it in the ... postscript.

(Yes this is a joke)

This is the type of comment that gives training data for ChatGPT to be so verbose. Ha!

i recently discovered that the Canadian government depends on this for some fillable forms, because it shows a message at the top that says "JavaScript is disabled" and all the boxes show errors. i couldn't get it to work on Linux and had to dust off a Windows machine (and it still didn't work in firefox, it needed acrobat reader).

I believe you need to rescan it into PDF to get it to work again.

Regarding #1: Your printer is just too slow. Try finding a printing company near you with a web feed machine, that should help with your FPS.

hahaha I wish you almost didn't include the parenthesis. I've had some clients who would definitely email me that point #1.

> 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)

Science fiction tells us this is only temporary. Print away, those papers will turn into magic in just a few decades!

It works for me. Maybe you need to upgrade your paper? What version are you using?

"The Javascript stops working when printed to physical paper."

You need to upgrade your paper that supports a minimum FR of 60hz.

3. I open it on my phone and it doesn't work at all. And that is a new phone with a current browser.
