Topic: The fundamentals of git usage and internals Presenter: Jimmy Thrasher When: Thursday, November 8, 7pm Where: Red Hat HQ, NCSU Centennial Campus, 1801 Varsity Dr, Raleigh, NC Map: Google Maps Slides: slideshare Video: YouTube

GIT : Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Git was initially designed and developed by Linus Torvalds for Linux kernel development; it has since been adopted by many other projects. Website: git-scm.com

Synopsis: Git is a powerful tool that suffers from an abstruse and leaky user interface and a somewhat steep learning curve. Using git effectively requires a working knowledge of how it functions. In this talk you will learn the very basics of using git along with what is happening under the hood while you use it.

Bio: Jimmy has been programming since he was 7 or so and is currently a freelance Rails and iOS developer. He has been using git since 2006 and depends very heavily on it for everything from production and side-project code to configuration. When not programming, he spends time with his family, attending church, helping to run a small classical Christian school in Mebane (Mebbin, not Meebane), and collecting hobbies. His superpower is spewing out useless trivia at tangents to the current conversation. Did you know that North Carolina has more varieties of fungus than any of the other lower 48 states?

OPEN SOURCE SHOWCASE Like last year, LUG members will be showcasing open source stuff (hardware, software or data) that they find interesting.

Sign up for a show-n-tell, or sign up to bring some food, snacks, goodies or beverages (adult or otherwise). You can also list ideas that you would like someone else to present.

The sign-up sheet is on the wiki: http://trilug.org/wiki/Meeting:2012_December_13

NOTE - The wiki contains the world's cheesiest spam protection. When you get the HTTP Authentication pop-up enter TRI in the username field and LUG in the password field. To edit the page, you'll need to log in to this wiki... this is not your shell account password. There's a link on the left to log in or create a new account.

In previous years, we've seen a wide variety of stuff in the showcase: music tools, 3D-printing, Arduino projects, BackupPC, a local distro mirror, pfSense, Rockbox, Bluetooth tools, ShairPort, networking tools.

Take a chance to geek out with the LUG, see what others are up to, and mingle a little, jingle a little.

Topic: OpenShift Presenter: Wesley Hearn When: Thursday, July 12, 7pm Where: Red Hat HQ, NCSU Centennial Campus, 1801 Varsity Dr, Raleigh, NC Map: Google Maps Sponsor: BCBSNC 1-800-324-4973

Wesley Hearn will be presenting OpenShift, a cloud computing platform as a service product from Red Hat.

This meeting is sponsored by Blue Cross Blue Shield of North Carolina, the state’s largest health insurance company, providing service to over 3.5 million North Carolinians. BCBSNC will have a representative at the meeting to discuss insurance plans that they offer, specifically for the self-employed.

Synopsis: Wesley Hearn will be going over what Cloud computing is and where OpenShift is inside the Cloud stack. After everyone has a grasp on Cloud computing, he will go over how OpenShift differs from OpenShift Origin. Then it is on to the semi-fun stuff, the different components of OpenShift Origin and how they work together. Once Wesley has gone over all of this, he will show you how to set up and deploy a local install(he will be doing it in KVM) so you can develop and test your application before you push it to OpenShift.

Slides and files Wesley's slides are available here: http://jknife.fedorapeople.org/TriLUG/

Topic: Triple Play: CACert + GPG + Freenet Presenters: Brian McCullough on CAcert + Jack Hill on GPG + Evan Daniel on Freenode When: Thursday, August 9, 7pm Where: Red Hat HQ, NCSU Centennial Campus, 1801 Varsity Dr, Raleigh, NC Map: Google Maps Video: 9Aug2012 TriLUG

This TriLUG meeting is a "Triple Play", with three related topics presented together.

• Brian McCullough will present CAcert
• Jack Hill will present GPG
• Evan Daniel will present Freenet

CAcert The first topic is an introduction to CAcert.org (www.cacert.org). CAcert is a community driven certificate authority (CA) that issues digital certificates to members free of charge. CAcert uses the Web of Trust (WoT) model to validate identities to provide more functionality to members. This presentation will introduce CAcert, it's mission, and it's services.

Freenet Freenet (freenetproject.org) is a distributed peer-to-peer data storage network. It enables users to store and retrieve documents, and provides strong anonymity and censorship resistance. Applications exist to use the network for file sharing, publishing and viewing web pages, social networking, and mail. The talk will cover the philosophy behind Freenet; an overview of data storage, routing, and cryptography; a programmer's perspective on using the network; and installation and setup of the software.

GPG An introduction to openPGP (rfc 4880) formatted keys and messages. After the talk, the audience should have the necessary understanding to participate in the global web of trust. To this end we will cover how to manipulate keys using the GnuPG command line interface, how to interpret portions of the web of trust to make real world decisions, and an overview of what to expect in a keysigning. I will also give motivating examples of why participating in the global web of trust is useful: authenticating email, and distributing software free from tampering.

Jack Hill is UNC-CH student and web developer with interests in scientific and educational software and functional programming.

Topic: OpenGL Presenter: John Riselvato When: Thursday, June 14, 7pm Where: Red Hat HQ, NCSU Centennial Campus, 1801 Varsity Dr, Raleigh, NC Map: Google Maps Example Code: OpenGLPresentation_Linux_v1.tgz Slides: OpenGL Presentation Slides Video Recording: 14 June 2012 TriLUG Meeting - Opengl

This TriLUG meet is an introduction in OpenGL. OpenGL (Open Graphics Library) is a hardware independent, cross-platform, cross-language API for developing graphical interfaces. It takes simple points, lines and polygons and gives the programmer the liberty to create outstanding projects.

This presentation will cover the following: - Introducing GLUT - Creating a 2D Square - Manipulating the Square - OpenGL Rotation &Transform - Adding 3D Rotation to the 2D Square - Generating a pseudo-complex objects with a simple for loop

Although OpenGL is cross-language, the presentation code will be displayed in C but understanding C is not needed.

Bio: John Riselvato is a Computational Science Intern at Shodor in Durham, North Carolina. John specializes in iOS development for Shodor, with two apps currently on the app store. Recently he had an opportunity to work on an OpenGL and CUDA project during his internship which sparked a large interest in OpenGL.
