GitHub New Features and Webhooks and API

The wonderful folks at OpenX are hosting this meeting, and they are also providing food. We need to provide a list of names to building security. RSVPs will be capped at 40. Contact Lan if you have questions. See end of description for OpenX map

Note: Our original speaker, Christian Weber, had to cancel, but he sent us another speaker, Jennie Ohyoung, who is also a Solutions Engineer at GitHub. The topic has changed slightly.

Final Note: Our actual speaker was Michelle Unger who was gracious enough to fill in at the last minute. Jennie Ohyoung was unable to make it due to flight cancellation. Much thanks to Jamie Wetzel for coordinating on GitHub side.


We will be covering the new features that were announced at GitHub Universe as well as how GitHub and other organizations use the GitHub's webhooks and API to enhance their existing workflows within GitHub.

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.


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.


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.


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


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.


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.
