Topic 1/2: Nodes in Blender for Geometry/Procedural Art

Speaker: John Flower

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.

Watching John use Blender is a thing of beauty—if you haven’t seen it, you’re missing out!

Topic 2/2: The Freedom Ladder

Speaker: Tom Ryder

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.

The journey begins with a single step: climb the freedom ladder

Tom will discuss a few things he learned in watching and participating in the initial IRC meetings for this campaign.

Topic 1/2: WSL (Windows Subsystem for Linux)

Speaker: Nick Skarott

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!

Topic 1/2: Competitive Programming—OhMyZSH

Speaker: Tim-Hinnerk Heuer

A short introduction to becoming effective with OhMyZSH with a focus on competitive programming with C++. This will be free-form, so contributions are welcome. I’ll show you how you can become effective with CP on websites such as HackerRank, LeetCode and CodeChef using nothing but the shell, Vim, and the websites. You’ll need to be very proficient with a programming language for competitive programming. I would recommend C++ and Python as the two languages of choice, but you can use a lot of languages such as JavaScript, Java, and many more.

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

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.

PASSWORD MANAGERS

Speaker: Tom Ryder

Re-using the same passwords on multiple sites causes a lot of security problems, but humans aren’t good at remembering a large number of passwords. Part of a good solution is a secure password manager. Tom will demonstrate a few Linux-friendly options, including his own favourite, password-store.

AV1

Speaker: Nick Skarott

AV1 is another in a line of freely available patent free video codecs. But despite the fact other free codecs exist like VP9, adoption of this codec outside of YouTube is next-to-non existent. What makes AV1 different to the point that has streaming giants like Netflix and Twitch to all the big hardware vendors like Intel, AMD and Nvidia joining the Alliance for Open Media (AOMedia)?
