March: rsync and Quasar
Date
7pm, Wednesday, 10 March 2021
Topic 1/2: rsync
Speaker: Tom Ryder
You’d think copying files between two different machines would be a relatively simple task, but it’s fraught with all sorts of subtlety and wastefulness. The rsync tool changed everything—fast, efficient, accurate file copies, right down to preserving file permissions, compressed transfer, and differential transfer—transferring only changed data. Tom will provide an introduction to command‐line rsync and a treatment of a couple of applications using it: the Grsync GUI, and the Dirvish backup system.
Topic 2/2: Quasar
Speaker: William Bell
William will demonstrate projects with the Quasar VueJS JavaScript
framework, and how to use it with Docker.
February: Imaginary Meeting
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.
December: Pizza & Old Pie
Date
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”November: Azuracast & AV1 Addendum
Date
7pm, Wednesday, 11 November 2020
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
data connection.
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.
October: A rocky outcrop.
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.
September: Stay Home
No meeting as our speakers are unavailable.
Networking help for member
Longtime member Palmerston North Linux Users Group John Eyres writes:
Hi, at [last week]’s meeting I asked if anyone could help with UPS and
networking for the guys I work with. They have muscular dystrophy, and can’t move/breathe on their own. The UPS works OK, but the batteries are getting old. Their cabinet is too small. … Please email me if you have any ideas. They do their own scripting, home
automation and development…
John includes some photos below. Please get in touch with him at computerjohney@gmail.com if you can help!
August: Hugo’s Life of Pi

Git
Speaker: Joseph Calkin
Joseph will talk about why Git is useful for version control. How it compares with SVN and how to use it.
Expanding Horizons
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 networkShould any of these pique your interest, we’ll finish by outlining how you can become licensed.
