Paul Nijjar has an old and slow computer, so lives his life in a terminal window as much as possible. He will describe some of the end-user applications he uses in this interface, including: web surfing, playing multimedia files, reading news, notetaking, and more. This presentation is beginner-friendly.
Update 2: Mikalai has provided his slides and his sample Dockerfile configs. See the attachments below.
Update: Paul's notes are here: https://kwlug.org/node/1174
and some sample config files for the utilities he uses are here:
Update: Due to an urgent family situation, John Kerr won't be able to present his LaTeX at the Law Library talk this month. The GDB presentation is still on, and we will have a roundtable discussion to close out the meeting.
Update: The sources for Sergio's slides are here: https://git.sergiodj.net/talks/gdb-intro-kwlug.git/ . A PDF copy of the result is linked below.
We will have a roundtable discussion focused on commandline utilities such as wget, curl, and other commands you might find in shell scripts. (Update: this did not happen.)

Victor Kofia will discuss NixOS and the Nix package manager. Nix takes a declarative approach to systems configurations, and all upgrades/rollbacks are atomic. It bills itself as "the purely functional Linux distribution."
Update: Bob took a screencast of his desktop during the presentation, which he combined with the audio from the podcast. Get it here: https://archive.org/download/kwlug-2019-04-01-openvms-nixos/KWLUG-OpenVAS-Proxmox-joined.mp4
Also, Bob provided some additional information following his presentation. He writes:

Note: The location for this meeting has changed. It will now be held at TriOS College.
Chris Irwin will give us a practical overview of UEFI (Unified Extensible Firmware Interface), the successor to computer BIOSes, and GUID partition tables, the successor to MBR tables.

Note: The location for this meeting has changed. It will now be held at TriOS College.
Tim Laurence will lead a discussion on tools you can use to identify bottlenecks in systems.
Brent Clements will talk about game emulators in Linux.
Note: Benjamin Tompkins's presentation on virtual machines has been postponed.
Important: We have had a last-minute switch in meeting location. For this month's meeting we will meet at our old location, St John's Kitchen.
Update: Jason has provided his slides, and written a blog post about this presentation's contents.
Lanny Cox will talk about tiling window managers -- in particular the i3 window manager.
Mikalai Birukou will give us an introduction to LXD, the Linux container management system. LXD provides a cheap way to experiment with different installations. He says this is a beginner-friendly talk for those who dabble on the command line or are beginner sysadmins.
Jason Eckert will discuss interesting SSH tips and tricks.
Update: Jason has uploaded his slides. He notes that the Star Wars ASCII art is available by telnetting to towel.blinkenlights.nl, and the book he mentioned is here: https://www.amazon.com/Crypto-Rebels-Government-Privacy-Digital/dp/0140244328
Khalid Baheyeldin has been playing with inexpensive Wifi and Bluetooth enabled microcontrollers. These can be programmed using the Arduino IDE or Micropython (which runs on the chip instead of an operating system). He will tell us about the Internet of Things (IoT) and how to use such microcontrollers to interface devices to things like home automation packages (e.g. Home Assistant), and much more.
Colin Knapp will update us on GitLab, the "open core" Git-repository manager. He calls his presentation "Creating Problems to Solve Problems in GitLab". Some of the topics he will cover include:
- How to organize and compartmentalize projects to reduce testing and growing pains.
- How to deal with increased complexity in compartmentalized projects
- The GitLab development cycle tools he uses when working on Tugthr.
- How he uses the built-in Kanban boards and commit messages to close tickets
- How GitLab-Runners work, and the difference between shared cloud runners and runners on your own hardware.
The remaining time will consist of an electronics swap meet. Do you have useful electronics that are no longer of use to you? Would you like to pick up some electronics for an upcoming project? Do you have stories to tell about cool older technology. Bring your things to giveaway and trade. If you have surplus, it will be sent to an organization that will dispose of it responsibly (Kwartzlab or Computer Recycling).
Note: This meeting will be held at a new location, the Google Community Space. Future meetings will be held at the usual location.
Also Note: Due to illness, James Kelsh will have to delay his presentation. He will reschedule.
In celebration of the Debian Project's 25th anniversary, Hubert Chathi will talk about his experiences as a Debian Developer, including technical components (such as building Debian packages) as well as non-technical aspects (such as Debian's history).
Madison Kelly will give a high-level overview of high availability technology.
Benjamin Turnbull will tell us about Qubes OS, a "reasonably secure operating system".
Tim Laurence automated the watering system for his garden using a Raspberry Pi. He will tell us how he did it. This will be a beginner-friendly presentation.
Note: For this meeting we are trying a new meeting location. See the 283 Duke St page for details.
James Kelsh will tell us about using the Linux desktop day to day, including work, fun, and maintenance. This presentation is intended to be accessible to new Linux users.
Khalid Baheyeldin will talk about the backup strategy he uses at home. He achieves versioned, incremental, off-site backups without relying on third-party services, using the dump utility. This presentation is intended to be accessible to new users.
Update: Khalid has posted his slides on his website: https://baheyeldin.com/linux/presentation-incremental-backup-linux.html
Colin Knapp will demonstrate the setup and use of Mail-in-a-Box.
Sandeep Johri is a non-technical end-user of Linux and free software. He will talk about his journey: how he bounced from distro to distro, how he landed where he is now, where he sees himself going in the future, and lessons learned from the experience. This talk is intended to be accessible for beginners.
Steve Walker (the CTO at Telium) will discuss the challenges facing the operators of VoIP based PBX equipment, and how to secure the PBX from hacking and fraud. The presentation will examine how and why hackers / fraudsters want to attack your PBX, and the risks and costs associated with these attacks. The presentation will then focus on the attack surface of the PBX, review common vulnerabilities, and describe detection of hacking / fraud, with an emphasis on Asterisk based PBX's. Finally Steve will take us through best practices in securing the PBX (and telephony environment), including the tools and techniques you should implement to protect your business (or home) system.
Since VoIP PBX technology is now within reach of the small business and home user, this presentation should be of interest to anyone involved with VoIP. If you already operate VoIP equipment and are wondering if this applies to you, here is a video showing a company that had to pay a $400,000 USD telephone bill after a single weekend attack on their VoIP PBX.
Jim Kelsh will demonstrate how to install Linux on a laptop. He may cover different installation methods and different distributions. This presentation is intended to be friendly to beginners to Linux.
Update: Jim's slides are here: 2018-03-05-linux-installation.odp
Charlie Drage will discuss his work (and contributions) to Kubernetes.
Mary Loubele will lead an interactive demonstration of how to use Elasticsearch to visualize the Twitter API. Bring your laptop loaded with VirtualBox. You will also need a Twitter login to access the API.
To participate, please follow these instructions: http://loubele.org/instructions.pdf
The virtual machine for you to download is here: http://loubele.org/Elastic.ova
The demonstration will cover the following topics:
- How to install Elasticsearch and Kibana on a virtual machine.
- How to get Twitter data from the Twitter API into Elasticsearch.
- How to build insightful visualizations with Kibana.
- How to perform text classification with Elasticsearch.
Update: Unfortunately, Joe had a serious personal situation come up, and won't be able to present this evening. There will still be a meeting but the topic is too be announced. In the worst case we will host a roundtable discussion. Our apologies for the last minute change.
Update: We had a roundtable discussion.
