I was just saying the low end chips have only "little" cores, no "big" cores, but they are still multi-core. AFAIK nobody makes single core Cortex A chips. Single core Cortex M chips are made, but those are really puny.

"cpu" is "core". Almost all phone CPUs are multi-core. The low end of phone (and Raspberry Pi 2 V1.2 and newer) CPUs is quad core ARM Cortex A53, which is a small slow in-order design, similar to the original Intel Penti

In Python, `"substring" in "string"` computes a boolean result suitable for use in an if statement. find() is for the second case. Python strings are immutable, so substring and split can be very cheap (pointing to same

This is only viable for small engines, like expander cycle is only viable for small engines. The specific energy of electric batteries cannot compare to that of kerolox or methalox. Closed cycle is not a new idea: https://en.wiki

Golang infamously tried to not use libc at all and just use the kernel syscalls by itself. I think they now do use some stuff from glibc? Or maybe they only use the libc on OSes where the kernel interface is not stable, like Windows? Also,

You can configure it to use crypto that is ok (and then use it to sign software packages or encrypt backups, like I wrote above, especially when interaction with gpg is done by scripts, not manually by humans, and key distribution is out of

You should have learned this paper last semester, as the paper is from 2015 and is relevant if you study DH. Anyway, for an application developer (as opposed to a crypto engineer), just use libsodium when you control both sides. If you need
