Something about an algorithm designing circuits that shouldn't have worked, but did. I might be mixing another story, but I think it was using electrical interference from an outside source to accomplish its task.

This was Adrian Thompson using genetic algorithms to design FPGAs: https://www.damninteresting.com/on-the-origin-of-circuits/

Someone posted a comment mentioning that coffee shops are a good metric for cultural development when trying to look for a new city

There's this discussion:

Off topic, but browsers should be appending the referrer page in the history list when openning a new browser tab. Countless times i've lost an article because i opened a link and much later discovered i had somehow closed the opener page.

This saved me a lot of time for these cases

I've been trying to find an email server which was mentioned in a comment a few months ago. I read through the setup instructions - the only point I remember is once it's setup one can add as many domains to it as one wants - if I remember correctly. There were several that popped up this past year, https://mailinabox.email this being one of them but I don't think it was the one I'm talking about. The setup instructions were clear.

Dunno if this is management 101 but someone mentioned casually the relationship between responsibility and authority. A mismatch between those two creates tension (employee dissatisfaction).

I have not found the comment or literature on the subject. Experiences at my day job tell me this is key to org/role design and management in general.

I read about it about a year ago. It was about a small program with 4 letters and someone posted 2 blog posts about it in a weeks time abusing the tool to see what it can come up with. The tool or program seemed to have an exploitative nature and seemed to be used in the security field. It worked with, I think binary files, but I recall it also allowed other programs to be ran on it. You provided an exit state and an input state and the program it needs to work with and tried all sorts of things within the provided program to reach the provided exit state. The blog post abused it to optimise to something interesting which I can't recall anymore. The writer of the blog post had more experience with it and already liked to toy around with it. It's not angr.

Iirc it 2as called something like nmap or jobn. Something with 4 letters and not the most straightforward name.

Please help me out.

Sounds like a fuzzer. Was it American Fuzzy Lop (afl-fuzz)? Doesn't quite meet your 4-letter criteria but sounds like a candidate.

It was a post or discussion, I think involving Peter Thiel talking about how innovation is in the world of bits not atoms now and that implies some unpleasant things about our society. Closest I could find was: https://news.ycombinator.com/item?id=6718654

What about this? https://news.ycombinator.com/item?id=5641799

Yes! Thank you. No wonder I wasn't able to find it as I strongly held my belief that it was 4 letters. Love this place.
