We'll have 2 presentations with month. One from Phil Waclawski on Krita held over from last month and the other from der.hans on Asciidoc
Phil Waclawski: Krita Basics - Tools, Layers, Coloring etc
Description:
Krita is a powerful painting program, designed for graphic designers and general artists. I will introduce the basic features it provides, along with some special filters, including G'mic. I will however not be able to demonstrate any artistic skills :)
Biography:
Phil has been a faculty member, focusing on open source software at MCC for nearly two decades.
Phil teaches a variety of course, including MySQL Database, PHP, Python, Javascript, HTML 5 and CSS, Linux OS, Internet Server Set up and more.
This summer, Phil will once again be offering a "MCC Multimedia Madness" summer camp for 6-8th graders. Over the two weeks I will cover a wide range of open source software, including GIMP, Inkscape, Krita, Audacity, Blender, Hydrogen Drum Kit, Tux Guitar, Openshot, Linux Multimedia Studio, work with green screen and more.
For hobbies, Phil has too many. Blacksmithing, archery, Leatherworking, Wood Working, Jewelry, Sound Recording/editing and SCUBA diving. Phil is also learning to play the Bass.
Phil has been using linux at home for desktops and servers since 1994.
der.hans: AsciiDoc - Plainish text for fancy output
Description:
AsciiDoc is a great text tool for documentation from simple notes to books. A text editor is all it takes. Since it's all text, AsciiDoc lends itself to revision control and revision control WebUI systems like GitLab and GitHub support it.
Biography:
der.hans is a technology and entrepreneurial veteran. Roles have included director of engineering, engineering manager, IS manager, system administrator, community college instructor, developer and DBA.
In his free time, der.hans endeavors to help build community through user group and conference leadership. He is chairman of the Phoenix Linux User Group (PLUG), BoF organizer for the Southern California Linux Expo (SCaLE) and founder of the Free Software Stammtisch.
He presents regularly at large community-led conferences (SCaLE, SeaGL, LFNW) and many local groups.
This month Phil Waclawski will give us an introduction to Krita and Ed Nicholson will explain DNSSEC and NTPsec

Ed Nicholson: DNSSEC DANE & NTPsec - Trust but Verify
DNSSEC DANE and NTPsec - The basic infrastructure of the Internet hasn't seen such significant improvement since Jon Postel's contributions to the original DNS RFCs. DNSSEC is operational authentication of information served by authoritative DNS servers. This is the dawn of the believable Internet. An important consequence has been the emergence of DANE or DNS-based Authentication of Named Entities. And that adds confidentiality to believability. Even as Internet naming gains this new robustness, similar efforts are improving our access to time services with the NTPsec project. While not all Internet infrastructure has left the era of blind trust, the names and times we depend on are now things we can verify. This presentation is about consuming and deploying DNSSEC DANE and NTPsec services.
About Ed:
Ed has been involved with Free Software for some time. His interests are in how people, organizations and populations use, create and experience information. He enjoys The Prescott National Forest as his "office" and The Valley of The Sun as a home away from home. Personal systems run either Fedora, Project Atomic, Android or OpenBSD.
PLUG is hosting a CryptoParty!
Show up on Thursday May 11th to get help securing your mobile and desktop electronics.
A CryptoParty is a global, decentralized, grass-root movement to help people protect their privacy.
The Phoenix Linux Users Group (PLUG) will have labs to help you setup things like secure messaging with Signal, VPN, TOR, a password manager and multi-factor authentication.
A CryptoParty relies on two resources. 1) people with the knowledge and desire to lead a lab; 2) people who want to take the lab and improve their security.
This month we will have a two presentations. Phil Waclawski will present "Using Hierarchical Data in MySQL, Trees vs Nests" and Ed Nicholson will present "Securing a SSH Bastion host with PrivacyIDEA and U2F"
Phil Waclawski: Using Hierarchical Data in MySQL, Trees vs Nests
Real world data is often made of hierarchical relationships, or "trees".
Representing that data in a Relational Database starts to get complicated as soon as you have more than two levels in your "Tree".
There are many strategies for handling such data, and I will cover examples of at least two of them (adjacency list and nested sets) and possibly more.
If you have access to a mysql instance, you can create the test tables and follow along, or get the code later.

Ed Nicholson: Securing a SSH Bastion host with PrivacyIDEA and U2F
Bastion Servers are an important tool for access control to your other
systems. PrivacyIDEA is a credential management system that can add
many types of authentication to your Jump Server, for example U2F.
FIDO Universal 2nd Factor Keys are a convenient standard implemented
by many to improve security. PrivacyIDEA is a great example of how
easy adding important levels of security to your systems can be.
About Ed:
Ed has been involved with Free Software for some time, and is most
interested in how people, organizations and populations use, create and
experience information. Recently, Ed is enjoying The Prescott National Forest
as his "personal office" and The Valley of The Sun as a home away from home.
Personal systems run either Fedora, Project Atomic, Android or OpenBSD.
The Installfest will will be held at Gangplank on April 1st 2017.|
