A giant ball of yarn containing notes on how to set up Debian/KDE Linux, with tips on useful software and commands.
First, we look for our default output and put its sink name in $DEFAULT_OUTPUT:
| #!/bin/bash | |
| # I do not want my screensaver to auto-activate after a timeout. | |
| # For some reason, you *have* to select a nonzero, finite timeout value for xscreensaver (there's no "infinity"). | |
| # I only want my screensaver to active when I lock my system by pressing [Meta]+[L]. | |
| # This hotkey is set up to launch this script, which | |
| # - starts the xscreensaver daemon, | |
| # - activates the screensaver (with lockscreen enabled), | |
| # - waits for it to terminate (unlocking logs an "UNBLANK" event), | |
| # - then kills the xscreensaver daemon. |
Connect the camera to the ethernet USB adapter via a CROSSOVER cable (or via an ethernet switch).
Install DHCP server:
sudo apt install isc-dhcp-server

Uses backward Euler integration (maxord=1 option), which can be very slow.
Set maximum iteration counts: DC iteration count limit (itl1, default: 100), DC transfer curve iteration count limit (itl2, default: 50), and transient analysis time point iteration count limit (itl4, default: 10) [ltwiki]_.
.OPTIONS maxord=1
I initially had some problems installing on my laptop, so decided to boot Ubuntu 12.04.5 LTS, 3.13.0-32-generic from USB and work from there.
For an automated installation script, see gpib_install.sh (and gpib.conf) below. The rest of this document describes the actions of the installation script step-by-step.
First, get the packages that are necessary to support Python bindings:
| /** | |
| * Compute the (Moore-Penrose) pseudo-inverse of a libgsl matrix in plain C. | |
| * | |
| * Compile uding: | |
| * | |
| * gcc moore_penrose_pseudoinverse.c -lgsl -lblas | |
| * | |
| * Dependencies: | |
| * - libgsl (GNU Scientific Library) | |
| * - libblas (Basic Linear Algebra Subprograms) |
