PulseAudio serves as a means to bridge the sometimes complex gap between sound sources from programs via ALSA and OSS libraries, and sound sinks to come out of actual speakers or other destinations, for appropriately mixed sound. In its role as an abstraction between the two, it’s capable of acting as a networked sound server, even for other operating systems that don’t use its native kernel, Linux. Stephen will demonstrate how this is done.
WireGuard is a replacement for IPsec and OpenVPN, offering secure communications over otherwise untrusted networks, using public key authentication both for authentication purposes and to form its routing table. It made its way into kernel space in Linux v5.6, which is as official a blessing as it gets (short of an RFC, maybe). There’s lots to love about WireGuard; Tom will show us the basics, along a few of the niceties that suit him (personally) down to the ground.
The Palmerston North Linux Users Group invites its members to join us in the Victoria Esplanade on Friday 17th December at 6:30pm, at the picnic tables by the pool, to share a pizza dinner in good company to round off what has been at times a difficult year.
Please bring $10 in cash to contribute to the cost of your pizzas, along with any drinks, and anything else you would like to eat as well (or instead).
These plans are, of course, weather-dependent; we will make another post and send out another email to the mailing list should the weather take a turn for the worse.
For the avoidance of any doubt: the Palmerston North Linux Users’ Group will not have its usual meeting at the Milson Community Centre this month, as the holiday season is upon us. There are tentative plans for a pizza meet in the Victoria Esplanade on the evening of Friday 17th December; we will post more details about this as they become available. Watch this space!
Nick has been spending the lockdown trying to teach himself software PBX systems for Voice-over-IP phones. He will discuss his journey through a couple of different platforms, and why he’s settled on using 3CX.
Scott will demonstrate the use of the Selenium browser automation tool, best-known as a means of running automated tests for software, and “other useful things”, including automatic web form completion. He says to expect surprising performance, along with a few gotchas…
Scott’s presentation will consist of demonstrating some uses of Selenium in Ubuntu with Java for automated testing, and in its own dedicated IDE.
As was the case last month, the Palmerston North Linux Users Group will not have its usual monthly meeting for October, due to continued uncertainty around the timing of the COVID-19 lockdown restrictions and our venue’s consequent availability. At the time of writing, we expect to see you all in November.
The Palmerston North Linux Users Group will not have its usual monthly meeting for September, due to uncertainty around the timing of the COVID-19 lockdown restrictions. We hope to see you all in October.
John will demonstrate the use of nodes in Blender, the free software 3D creation suite.
In addition to creating materials as just described using all the settings on all the materials panels, Blender allows you to create a material by routing basic materials through a set of nodes. Each node performs some operation on the material, changing how it will appear when applied to the mesh, and passes it on to the next node. In this way, very complex material appearances can be achieved.
The Free Software Foundation’s position at the forefront of software freedom for users, with instruments like the GNU General Public License and the Defective by Design anti-DRM campaign, has often led to criticism of them as too hardline, or too purist, especially for less technical people. A more recent effort made in part to dispel this image has been the Freedom Ladder, a campaign to encourage users new to free software to take a first step, simply by replacing one proprietary program they use with a free software substitute, and building on their new freedom gradually from there.
By supporting them in taking a step at a time, we’re confident that we can help bring more people to a fully free setup than ever before. We’re calling this campaign the “freedom ladder,” and we need your support to help others begin climbing it.
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.
WSL is the Windows Subsystem for Linux, a way to run not only console based Linux applications but also now GUI Linux applications on a Windows 10 host. Nick will walk through the setup and demo its capabilities.
Topic 2/2: Practical PXE boot
Speaker: Stephen Worthington
Bring your laptops! Stephen brings us a Part 2 to PXE booting—run a Linux distro on your machine tonight—without it even touching the hard drive—over a live network!
Hopefully we can all learn something in this session and most importantly—have fun.
Topic 2/2: Gemini
Speaker: Giovanni Moretti
Gemini is a new internet protocol which:
– Is heavier than gopher – Is lighter than the web – Will not replace either – Strives for maximum power to weight ratio – Takes user privacy very seriously
