September 13, 2022: RTFM Duo

This month, we had a couple short RTFM-style presentations: First, Brad Vokey presented on bpytop/btop++. Next, Trevor Cordes (who normally prefers working quietly behind the scenes on coding or newsletter editing) presented on configuring rsyslog to suppress annoying log messages.

Bpytop - a Python port and continuation of bashtop(1)

This month Brad Vokey gave us a quick demonstration of byptop, as well as its new sibling, btop++. Bpytop is a colorful, efficient, responsive, terminal resource monitor that shows usage and stats for your processor, memory, disks, network and processes. Written in Python by the original author of bashtop, the author claims it is faster and much better supported. (Btop++ is essentially a rewrite in C++.) Add some bling to your original old top(1) command!

Fighting the PHPower with rsyslog

Help! The new PHP8 has made normal, everyday scripting practices an error on screen or in the logfiles. Fight the power and reclaim your PHP sanity using rsyslog and its filtering options. But beware, rsyslog itself is a minefield of inexplicableness. Trevor Cordes led us on a quick and easy path to victory over PHP, and any other daemon you may disagree with!

Trevor has made his presentation slides, as text files in a .tar.bz2 archive, available online.

Date change: October 18, 2022: Tracking Aircraft with an RTL-SDR and a RaspberryPi

Automatic Dependent Surveillance-Broadcast, or ADS-B, is a modern aircraft safety system that broadcasts an aircraft's identification and position data to other aircraft and ground stations. Using an off-the-shelf RTL-SDR receiver and a RaspberryPi, we can decode these messages to track aircraft in our vicinity. Wyatt will show how to install the dump1090 software used to decode the messages, and the different third-party aggregation sites that collect ADS-B information to provide real-time flight tracking around the world.

This will once again be an online meeting. Stay tuned to our muug.ca home page for the official URL, which will be made available about a half hour before the meeting starts. (Reload the page if you don't see the link, or if there are issues with connecting.)

For those having video performance issues, Alberto posted some useful tips on hardware acceleration settings to the roundtable mailing list.
