The author claims that the capacitance of a cylindrical plate is proportional to its diameter rather than its area.

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!

M_Map is a set of mapping tools written for Matlab (it also works under Octave). M_Map includes:
1. Routines to project data in 21 different projections (and determine inverse mappings), using spherical and ellipsoidal earth-models.
2. A grid generation routine to make nice axes with limits either in lat/long terms or in planar X/Y terms.
3. A coastline database (with 1/4 degree resolution).
4. A global elevation database (1 degree resolution).
Hooks into freely available high-resolution coastline and bathymetry databases.
5. Other useful stuff.

I have not found out which license is used.

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.
