Git Foundations: Basic Concepts and Definitions

This month, we are hosted by Everbridge at their training center.
Everbridge is also sponsoring food and drink.

Note: The GitHub Webhooks talk with Christian Weber originally scheduled for tonight is posponed to Dec. 8th (next LUG meetng) due to speaker illness. We apologize for the inconvenience.

Mike Weilgart graciously agreed to be our last-minute substitute with his well-received "Git Foundations: Basic Concepts and Definitions," which was presented at UUASC and LOPSA-LA.

Topic

Dozens of commands! Hundreds of options! Git has dumbfounded sysadmins and developers alike since its appearance in 2005. And yet, this ingenious software is among the most fantastically useful ever developed. Learn Git from the ground up and the inside out with Git Foundations Training! This talk explores Git’s internals in depth.

Bio

Mike Weilgart has loved maths and computers all his life. Graduating high school at the age of 13, he thereafter worked in a variety of positions including software QA, calculus teacher, and graphic design, before resolving to put his love of computers to professional use as a Linux sysadmin and trainer. Mike currently consults at a Fortune 50 company as an automation specialist, and enjoys nothing more than training people to full mastery of their tools.

3D Printing, What is it good for anyway?

This month, we are hosted by New Matter, a new 3D printing company incubated at Idealab. Please RSVP on Meetup or email Lan (L dot Dang at ymail dot com). We'll head out to Du-Par's Restaurant and Bakery (214 S Lake Ave, Pasadena) around 9:15pm for a late dinner.

Abstract:

Dave Flynn will share his extensive experience with 3D printing from the past 4 years, as well as his motivations for designing and building his own 3D printer. Specifically, his experience is with the RepRap style of 3D printers.

The presentation will be short as Dave much prefers answering questions.

We welcome the 3D printing community--whether they are experts or neophytes-- to share the things they've printed and spark a conversation about what we can do with 3D printing, how to get started, and how 3D printing can be used for art, home, hobby, and work.

Please contact Lan if you are bringing something for show and tell or want to do a lightning talk.

Text Processing at the Linux Command Line

Abstract:

Text is everywhere but not always in a useful form. On any given day we encounter dozens or hundreds of data formats. Some formats are focused on presentation while others focus on structure at the expense of presentation. Many times the information we need has to be found, disentangled and manipulated before it is useful. The easier we can navigate across these boundaries, the more freedom we have to find new uses and insights.

Linux offers a rich array of commands and tools for text processing at the command line. This talk proposes a classification for different types of command line processing tasks and then explores some of the common tools available within each category. Many of these tools have a host of options. Some useful but lesser known options will be highlighted. The tools will then be applied to a number of examples covering data extraction, processing and presentation.

Bio:

Joel Steres spends most of his time at the command prompt. He is still amazed at how small specialized building blocks can be combined to achieve big results.

How to make the world ring for you...

Abstract:

What do amateur radio operators, small businesses, giant corporations, E911 systems, and Linux hobbyists all have in common?

Well, besides using Linux, they all are using an application called Asterisk, in one of its many forms, to handle telecommunications.

Amateur radio operators can interlink plain old telephone systems with repeaters, small businesses can appear to the world to be a large corporation with custom interactive voice response menus, and hobbyists can lower their home phone bill to as little as a $1.00 per month with $0.0015/minute call charges.

Not to mention to have a phone number virtually anywhere in the world termin ate at your home,

The presentation will introduce Asterisk, its applications, basic Python scripting, and many other things.

P2P and the World of Tomorrow

This month, SGVLUG and InfoSec Syndicate member Ray S will give a brief history on P2P software technology, applications and implementations.

Abstract:

The P2P and the World of Tomorrow presentation will address a brief history on the development on P2P software technology, applications and implementations by the end user. Applications such as Audio Galaxy, Napster, Direct Connect, Gnutella, Freenet, eDonkey2000, Kazaa, Morpheus, BitTorrent and Soulseek will be discussed in the presentation. End user usage patterns based on net cultural behavioral norms will be addressed as well as the development of conflict as result of practicing such norms on a end user case-by-case basis. Media attention and changes in policies of governance in relation to P2P technology and usage are topics that will be touched on in the presentation. New changes in P2P technology being made to maneuver difficulties that have arisen from changes in governance policies are addressed later in the presentation. The presentation's conclusion addresses technological responsibility and safety practices the audience can use to prevent themselves from becoming a marginalized end user as in the cases discussed earlier in the presentation.
