I don’t really understand how OCRing a PDF could be more accurate than reading the text nodes.

Another thing to consider is OCR works well for English but not so well for other languages.

Yes it’s not a safe general rule. I can do it because I first classify the statement into a document_type and then run special code for specific document_types.

I agree with you, it's not safe to have a rule saying "non-black means invisible".

I should have made it clear in the blog post, but the first thing I do when processing a PDF is I identify the document_type. Then I run special rules for that document_type.

So the "non-black means invisible" rule only applies when processing this document_type.

I did try method number two, and it worked. I should update this post.

New comment by 4pkjai in "The 2-Year Apartment Rule"

4pkjai — Thu, 18 Jun 2026 08:50:51 +0000

Damn I was hoping for some sort of explanation. This rule doesn't apply to me, my apartments are pretty good even after two years.

I do end up changing apartments after the two year lease period because I get bored of the area or the landlord raises the rent.

I do this to see if text in a PDF is exactly where it is in some other PDF. For my use case it works pretty well.

I used MonoGame to port my XNA games to other platforms.

It’s really good, also it was very cool as a junior developer to see the code for the methods I used.

I worked in a team of four between 2017 and 2020 this way. I really enjoyed it. After that I joined a company that worked with PRs. Felt like such a waste of time.

I started off using this back in 2009 when I wanted to make an adventure game.

Really enjoyed it back then, great to see it’s still around

I did the 2014 version of this to learn Swift to port an Android app I made.

He’s an excellent teacher!

I think he worked at Apple so he shared a lot of the history behind the APIs in iOS going back to the NextStep days.

When I was a university student in 2009 a lecturer accused me of plagiarising a c++ win32 project I submitted.

It turned out he ran it through a plagiarism detector and multiple lines of code where identical to lines in their database.

It was very silly because there’s a lot of boiler plate code in win32 projects

Is this something you think they can or should fix?

We do this in game development .

Watch someone play the game for the first time. Don’t interfere. See if they can figure out how to play.

Psst Want to see a cool bug?
