- What every systems programmer should know about lockless concurrency
- “Seasoned programmers are familiar with concurrency building blocks like mutexes, semaphores, and condition variables. But what makes them work? How do we write concurrent code when we can’t use them, like when we’re working below the operating system in an embedded environment, or when we can’t block due to hard time constraints? And since your system transforms your code into things you didn’t write, running in orders you never asked for, how do multithreaded programs work at all? Concurrency—especially
on modern hardware—is a complicated and unintuitive topic, but let’s try to cover some fundamentals.”

I’ve updated the little script I wrote to keep track of which comments are new on LJ and Dreamwidth (LJ now does this automatically in its default style, DW doesn’t, by the looks of it). Thanks to sally_maria for alerting me to both the problem and the solution.
Userscripts.org is long dead, so I’m now hosting it on my site.
