An assertion documents the expected state of specific program variables at the point where the assertion is written, in a testable way so that we can find program bugs — logic errors that have led to corrupted program state. Assertions are only about finding bugs, not doing program work. Bonus: [[assert: ?

At the Linux Plumber's conference there were at least 24 talks on eBPF. So instead of a static HTML website, JavaScript lets you define mini programs that run on events like mouse clicks, which are run in a safe virtual machine in the browser. Programming in eBPF directly is incredibly hard, the same as coding in v8 bytecode.

You see, because TCP is a much older protocol and not made for just loading web pages, it doesn’t know about A, B, or C. Robin Marx.
