It can be much simpler if you're willing to write a couple lines of assembler: use an 8-byte file that contains one 64-bit counter, mmap() it, mlock() it, and use atomic CPU instructions to increment and read it.

> b) just write blindly to file and pretend concurrecy doesn't exist This is likely what was done. Nobody really cares if a hit counter on a web page loses a few updates.

And how on earth could a website update its own HTML to show the new count? Geocities days were magical. I wonder if kids today have similar thoughts about Twitter profiles and such. It’s probably much easier to pick up the knowledge — back then, it was balk…

I think the early-00s was when it started to shift from something stigmatized to something that a person could be into and still be cool—or, at least, not regarded as automatically weird. By 2010 the shift was basically done, and The Great Techbro Wave was washing over the industry. It's been super weird to watch the common idea of a computer person shift from someone with bad skin and shit posture in a pit-stained b…
