The statement «"p.s. "Why didn't you write it in Rust?" -- I take that question
seriously, and did some measurements. Rust does not do as well for
this purpose as Go.» is interesting.

jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

Cscope is a developer's tool for browsing source code. It has an impeccable Unix pedigree, having been originally developed at Bell Labs back in the days of the PDP-11. Cscope was part of the official AT&T Unix distribution for many years, and has been used to manage projects involving 20 million lines of code!

This repo is an implementation the Plan 9 cpu command, both client and server, for Linux. More detail is available in the CPU chapter of the LinuxBoot book. https://book.linuxboot.org/cpu/
Unlike the Plan 9 command, this version uses the ssh protocol for the underlying transport. It includes features familiar to ssh users, such as support for the ssh config file.

The cpu command lets you log in from a local system to a remote system and see some or all of the files (how much is up to you) from the local system.

This is wonderfully convenient for embedded systems programmers. Because some or all the files can come from your local machine, including binaries, the only thing you need installed on the remote machine is the cpu daemon itself.

The section https://www.satdump.org/posts/1.1.4-release/#the-switch-to-jemalloc sounds interesting, perhaps this could be useful for Gpredict?
