April Meeting: Using VXLAN to network virtual machines, containers and other fun things

Date: Tuesday, April 19th
Time: 7:30pm
Location: UVU Business Resource Center

John Nielsen will present about VXLAN, a relatively new protocol for transporting a large number of virtual Ethernets over any IP network. It draws from and improves upon both VLANs and point-to-point network tunnels. Once a “virtual tunnel end point” is configured for one or more VXLANs it discovers the other end points and hosts within each network automatically. This presentation will introduce VXLAN in greater detail, compare it to VLANs and traditional L2-over-L3 tunnels, and describe and demonstrate several use cases for VXLAN on Linux and BSD including containers, virtual machines, and wireless bridging.

November Meeting: Automating repetitive tasks

Date: Tuesday, November 17th
Time: 7:30pm
Location: UVU Business Resource Center

Colton Wolkins has been programming since 2004 and is very familiar with the term “Programmers are lazy”. Being the “lazy” programmer that he is, he tends to follow the DRY (Don’t Repeat Yourself) principle and found that he would continually repeat the same commands while programming in Linux. This month, Colton will be talking about how he came to creating Renzoku <http://github.com/frostyfrog/Renzoku> and how it has changed his programming workflow and made his life easier.

Just go in the front doors, and follow the signs. We’re usually in a conference in the back of the main floor. There will (allegedly) be pizza provided by TekSystems.

October Meeting: Manipulating video in open source ways

Date: Tuesday, October 20th
Time: 7:30pm
Location: UVU Business Resource Center

This presentation is intended to give an overview of the various open source tools and libraries available for processing and manipulating video data. I will go over tools for video playback, simple and advanced video editing, command-line utilities, and DVD/Bluray ripping. Finally, I’ll do a live-demo of a complete video workflow from capture to final rendering.

Doran Barton has been a Linux user since about 1995 and has been working with digital video editing since 1997. Linux became his primary platform for video editing in the mid-2000s. Doran has overseen video recording for Openwest for several years and is currently working on his first video documentary project.

September Meeting: Sphero On

Date: Tuesday, September 15th
Time: 7:30pm
Location: UVU Business Resource Center

Sphero is a fun little robotic orb that you connect and program wirelessly. Brad Midgley will demonstrate this with a beaglebone black using nodejs (small computers make great companions to robots). He’ll demonstrate the code he has and code improvements with the group.

August Meeting: Crypto Algorithms

Date: Tuesday, August 18th
Time: 7:30pm
Location: UVU Business Resource Center

Aaron Toponce will talk about symmetric and asymmetric cryptography, and the current cipher algorithms covering them, such as RSA, AES, and ECC. He’ll talk about how encryption and decryption work, as well as digital signatures and verification. He’ll include the Diffie-Hellman key exchange, and the SSL/TLS handshake.

Further, given the disaster on OpenSSL during the year of 2014, he’ll talk about the major threats that compromised online security with SSL and TLS. He’ll explain the differences between:

* SSL 2.0* SSL 3.0* TLS 1.0* TLS 1.1* TLS 1.2* TLS 1.3 (draft status)

He’ll talk about the implemented ciphers and hashes, including their advantages and shortcomings. He’ll discuss the attacks that took advantage of these shortcomings, such as Heartbleed and POODLE. He’ll show how system administrators how to properly secure their web, mail, and other servers that require SSL/TLS.

Finally, he’ll discuss OpenPGP and OpenSSH concepts. By the end of this talk, the basic mysticism that is crypto should be all cleared up.
