    Latest mention: Measurements should always have units | reddit.com/r/coding | 2020-12-24

    Mateusz Pusz has a proposal to add something similar to the C++ standard. His reference implementation also fixes one of the minor annoyances of Boost.Units, which is crazy long compiler error messages when you mismatch units. I hope his proposal makes it into C++23.

    C++17 RISC-V RV32GC / RV64GC userspace emulator library

    Latest mention: Ask HN: What Are You Working On? | news.ycombinator.com | 2021-01-14

    I am working on ultra-low latency emulation. I have a RISC-V emulator (https://github.com/fwsGonzo/libriscv) that I am creating to fork really fast.

    https://cloud.nwcs.no/index.php/s/iP6aYJaoBtXbbqM

    Those measurements is from a production environment, meaning these numbers are very real! In a synthetic benchmark the fork happens at just ~200 nanoseconds, and it's really a meaningless number.
