OCRing this is a nightmare and is a good benchmark to any self-proclaimed good OCR/vision model. I think though it could likely be easily OCR'd if you give the image to any decent agentic harness with a good vision model, e.g. newest Claude/GPT ones, and tell them to split the image per lines, and then just OCR each line individually. I wonder if the script itself was written by an LLM before obfuscation? There seem…

Definitely LLM. No humans write that many comments.

Since LLM's are mimicking our code my guess we do...

Earlier quoted context omitted.

Didn't know Safari had this. Looked it up, you put mouse over text, then just select and copy it - very cool! https://support.apple.com/en-gb/guide/safari/ibrw20183ad7/ma...

There’s a whole bunch of hidden features that no one seems to be aware of. Preview has pretty good background removal. Notes will transcribe audio from audio files.

Notes will do OCR as well. Trigger the feature, point the camera at something, and it will input just the text.

This reminds me of a T-shirt I once saw that read: perl -e ' "$a="etbjxntqrdke"; $a=~s/(.)/chr(ord($1)+1)/eg; print "$a\n;"' It's cursing. Don't run it if it might offend you. Upon seeing this, I decided to golf and came up with a shorter version: perl -e "print chr 1+ ord for split //,'etbjxntqrdke'"

or

  raku -e 'say "etbjxntqrdke".comb.map({chr .ord + 1}).join'

while base64 can be considered obfuscation in this context and its inverse as decoding I can't help but feel this title is overselling and catering to a rather cyber-cheesy marketing campaign at that.

Yeah, its a bit of a cheat. The best obfuscated C programs have the source looking like a Christmas tree (or something) and then play an xmas song (or whatever)

I love this shirt! Here's a nice video from the actual designer about the process of making this shirt (including intentionally making it hard to OCR): https://youtu.be/jocGLiecpjU?t=526

It would probably be quicker to type it in than figure out how to OCR it. It would be like typing in a game from a COMPUTE! magazine 45 years go.

the base64 thing they did feels like a cheap version of that green-obscure-symbols-raining-on-a-terminal animation in The Matrix. should have gone with "Hack the Planet" instead ...

What is it about this that makes it particularly hard to OCR?
