As an electrical engineer: you'd be surprised how many people "discover" long held truths like that you can use the MPN ("Manufacturer Part Number") of a device to find it's documentation and that this documentation sometimes contains useful data.

It's everywhere. Just recently (a couple of months ago) on HN there was a story about an SQLite-but-rewritten-in-Rust [0], how they've discovered some peculiarity in SQLite file format by reading its source code. Except, of course, this peculiarity has been documented for decades, on SQLite's official site. How did they manage to write SQLite-compatible DBMS without reading the official documentation of the file format, I have no idea.

It does not bode well when you're writing a database engine and not revealing any bugs ... because all your test datasets are under 1GB.

I don't think the author was presenting it like some kind of "new to the world" discovery. It was just something they recently learned.

The blog post from OP is mostly AI generated - quite a few tells in the style of writing.
