hackers took over Notepad++ update servers and distributed a malicious update for the app. The update servers were vulnerable for roughly six months 😬 www.theverge.com/tech/872462/...
Notepad++ updates got hijacked for months and could have spied for China
The hack was resolved in a December update.

If you are designing an API with a coding agent it really helps to get it to a point where the coding agent can deeply inspect the internal state of the algorithm to help debug complex issues.

My kid had to learn the square roots up to 20 for a school test.
Her teacher mentioned she would ask her own kid questions throughout the day to help it memorize them. That gave me the idea to build an app that would do exactly that.

I also expect OpenAI to similarly complain to regulators at some point
