We have had to cancel this meeting due to the speakers, meeting chair, and Vice President all being unwell (!). Nothing serious for any of them (and negative rapid-antigen tests), but we understand that people are extra-cautious given the COVID-19 pandemic. We have asked the speakers to reschedule and hope to see you all next month.

Topic 1/2: systemd: Heresy and Hearsay
Speaker: Tom Ryder
Of all the holy wars for GNU/Linux systems, the dominance of systemd is among the most controversial, with one suite of tightly-coupled software tools taking over so much of the system above the kernel. Being deeply unpopular in traditionalist Unix circles for his systemd apologia, Tom will attempt to explain himself for holding his more nuanced position.
Tom is a bearded chap, and hacks facing black screens with white writing for Inspire Net…a fan of Vim, and tappy-tappy over clicky-clicky.PLUG Vice President John Flower’s succinct biography
Topic 2/2: Docker and WSL in Windows
Speaker: John Eyres
John Eyres will demonstrate the use of Docker and WSL in Windows with VSCode, continuing on Nick’s WSL topic from last month.Continue reading “July: Face Your Daemons”

Topic 1/2: PXE Boot
Speaker: Stephen Worthington
Topic 2/2: MUNTing DOSBox with RetroArch and a (sorta) SoundCanvas
Speaker: Nic SkaContinue reading “April: Reel Stuff”
Dreadfully sorry, no meeting. See you in March to geek out on geeky stories and to do democracy and pick club committee for the coming year.
7pm, Wednesday, 09 December 2020
End of year get together. We’ll talk bollocks, eat pizza, and play arcade games on an old telly made smart by a Raspberry Pi.Continue reading “December: Pizza & Old Pie”

Topic 1/2: Azuracast
Speaker: Nick Skarott
Azuracast is an open source Internet radio automation solution deployable via Docker or Ansible. Nick will explain how he has used it to stream his own content over the Internet to enjoy on the run anywhere there is a mobile
Topic 2/2: AV1 Part Deux – Developments and VMAF
Speaker: Nick Skarott
Just over one year ago Nick demonstrated at PLUG the beginnings of the next generation open source video codec, AV1. A lot has changed in that time in the AV1 space and it’s fitting to look at the developments, and in
particular, the work NetFlix has done (and then open sourced) with the University of Southern California and the Laboratory for Image and Video Engineering at University of Texas’ Austin campus, called VMAF.
Date: 7pm, Wednesday, 14 October 2020
As the internet grows into every corner of our lives, so too does pervasive surveillance within it. Your activity can be intercepted, analysed, and abused by many interested parties, from credit card thieves to abusive nation-states. The privacy implications of everything being networked in this way are enormous, and in most cases very poorly understood by the general public. Worse, unscrupulous and incompetent vendors take advantage of this confusion, and peddle white-labelled security snake-oil that gives users a false sense of security.
A better option for defending yourself from such surveillance is the use of the Tor network, which routes your internet traffic through multiple computers on the internet in such a way that your privacy is protected. Tom will explain the basics of how Tor works, and list some of the benefits and caveats in using it.
No meeting as our speakers are unavailable.
7pm, Wednesday, 12 August 2020
Nic Skarott will discuss the great hardware that is Raspberry Pi 4.0 whilst John Flower will show how he designed this year’s Hugo awards using Blender and Inkscape.Continue reading “August: Hugo’s Life of Pi”
7pm, Wednesday, 08 July 2020
Speaker: Joseph Calkin
Joseph will talk about why Git is useful for version control. How it compares with SVN and how to use it.
The Intersection of Amateur Radio and Computing
Speaker: Giovanni Moretti – ZL2GX and Graeme – ZL2GZ
Amateur radio is a hobby of exploring the limits of radio, electronics and digital technologies. Once licensed, you’re allocated a worldwide-unique callsign and can operate (and build) radio equipment capable of international and space-based communication.
Being an interest centred on electronic communication, there’s naturally a strong overlap with computing, with Arduino and Raspberry Pi and Linux being widely used. There are many facets to the hobby ranging from the seriously technical through to providing communications support for search-and-rescue (SAR), Civil Defence and Amateur Radio Emergency Communications (AREC).
In this talk, we’ll will give an overview, including how you can:
communicate internationally from your backyard (without the Internet or cell phones) use both voice and digital modes on-air design and build radio transceivers and antennas send signals 2000km using just a Raspberry Pi and a micro-transmitter. use Linux to link into international Internet-linked DMR and DStar (digital mode radio) networks become involved in the ongoing efforts to build a regional radio-linked TCP mesh network
Should any of these pique your interest, we’ll finish by outlining how you can become licensed.Continue reading “July: Some Git with a Radio”
