Does this mean that 0 Hz bandwidth leads to the ideal clock?

I assume this uses thunks not unlike some lazily-evaluated languages?

Doesn't this mean that non-blocking reads from /dev/urandom can now potentially return -EAGAIN (at e.g. very early boot time)? I think that's enough to subtly (nondeterministically) break userspace, in the short time wi

https://man7.org/linux/man-pages/man2/membarrier.2.html provides a good example of when a processor memory barrier is eliminated but a compiler memory barrier is still required.

See https://www.fsf.org/campaigns/free-bios.html for the rationale. Basically, FSF had to make a compromise here. If you use Flash ROM (or other writable medium), the firmware counts as a nonfree software . However, i

Make sure you don't roll your own crypto on your way, though. Unless when it somehow becomes the absolute necessity...or it's for your dissertation.

It's worth noting that Fedora/RHEL's postinstall is generally less intrusive than Debain's, though. For instance it doesn't just automatically create databases or starts/enables services.

(Commenting here since the other thread is going nowhere) To clarify, the main property of a non-blocking algorithm is that it's exclusively composed of simpler, smaller ("atomic") operations that demonstrate time-bound/

OpenBSD does something similar but in a reverse manner. It's called Kernel Address Randomized Link (KALR). What it does is bundling kernel object files into an archive, which is linked at boot time to form the final kernel image. Note

Is there anything else that should be done except flushing D-cache and invalidating I-cache? I'm genuinely curious.

Is there something wrong in particular for using built-in fixed-point types for timestamps? Yes, overflow/underflow issues and yada yada, but virtually every type can be mised in its own way.

...why are you even talking to some stranger here then, is it worth enough to risk being exploited with a RCE 0day Like, uh, just define a clear threat model, accept risks, and move on??? Or just don't use computers

No, that's irrelevant here. PNGSource embeds code in ancillary chunks. That's it. No code execution. No steganography (yet).
