Programming language terminology lesson: Closures

In the vast majority of languages that support them, a block is a closure! Blocks, closures, lambdas — they’re all just different words […]

The issue with runaway > threads rarely comes up for a simple reason – most processes end up > pausing for I/O (user input, db access, file access, sockets […]
