Demos Share your passion by bringing a project or product to show off. As we get more demos we'll try to keep the list up to date!

New Search for MediaWiki Nik Everett Day job is writing a new search for Mediawiki which is pretty cool. Can show it off if anyone cares to see it.

The Privacy-Protecting Tails Linux Distro Sean Alexandre Come try out Tails, a live USB Linux distro aimed at preserving your privacy and anonymity.

LibreOffice Base Demo Jeremy Davis I have built a couple of LibreOffice Base databases I would like to share. One I use weekly to publish the Triangle Area Career Development Newsletter. The DB helps to manage and gather meeting info of our local groups and builds the newsletter formatted with HTML. I have built a nice task tracker to show off as well, which was developed over time at my work place in MS Access but then recreated with LibreOffice Base as a project to compare the two. I will demonstrate valuable timesaving features of the awesome LibreOffice Base program, which comes free with most Linux distros.

November 14 Meeting: Cryptography and GPG

Cryptography has been in the news a lot lately. We'll start with a quick overview of some of the major recent headlines, specifically about the NSA's attempts to circumvent and break encryption and what experts are recommending to stay as secure as possible online. This will be followed with a high-level overview of cryptography. We'll look at where it's been made easy to use, and were it's not so easy. Then we will dig into the details of using GPG from the command line, to encrypt documents and to verify software packages.


Sean Alexandre is a Senior Software Developer at SAS Institute, where he's been working on different front-end applications for the past 12 years. Lately his interests have been on Linux and free software, with a focus on distributed systems and defensive security.

October 10 Meeting: Choosing a secondary DNS server, now with data!


Topic: Choosing a secondary DNS server, now with data! Presenter: Aaron Joyner When: Thursday, 10th October 2013, 7pm (pizza from 6.45pm) Where: NC State Engineering Building II Room 1025, Centennial Campus Parking: The parking decks and Oval Drive street parking are free after 5pm Map: Google Maps Video: YouTube

Abstract: Are you responsible for a DNS domain, perhaps professionally, or a "vanity" domain for your personal email?  Have you given much thought to the DNS resolvers for that domain?  Every domain requires at least one DNS server, and everyone has probably heard that they should have a geographically disparate secondary server to hedge against catastrophic outages (network, building, etc).  Assuming you don’t have the luxury of a globally distributed set of datacenters, where should your secondary DNS server be hosted?  This talk will present one man's quest to answer that question, along with the data used to visualize and understand the available options.  There will also be a brief discussion of how that data was collected, and open source code (in Go, to do it yourself.

Bio: Aaron S. Joyner is a Sr. Systems Engineer in the Site Reliability Engineering (SRE) group at Google. He has been working as a SysAdmin for more than 15 years at companies such as Global Knowledge,, and MWG Biotech. When living in Raleigh, he was actively involved with the Triangle Linux Users Group, serving on the steering committee as SysAdmin in 2004-2005, and giving talks on DNS for NC*SA and TriLUG. Since joining Google in 2005, he has helped to maintain their internal DNS infrastructure and been primarily responsible for designing, implementing, and supporting Google's serial console systems.  For the past ~4 years, he has been leading a team of SREs responsible for supporting production authentication and machine management systems.

September 12 Meeting: Open Source: the Nanotechnology of the Cloud


Topic: Open Source: the Nanotechnology of the Cloud Presenter: Michael Tiemann When: Thursday, 12th September 2013, 7pm Where: NC State Engineering Building III Room 2207, Centennial Campus Parking: The parking decks and Oval Drive street parking are free after 5pm Map: Google Maps Video: YouTube Slides: PDF

Michael Tiemann started the world's first open source software company, thereby placing the topic of open source into the field of economics.

Ignored for several years, open source has helped to rewrite the rules of economics, and has become an important subject among Nobel laureates. After reviewing 20+ years of Nobel Prize lectures in economics, Tiemann has synthesized a new perspective on the economics of cloud computing and the continued role that open source will play in the development of this new paradigm.

August 8 Meeting: Patents and Linux in Context


Topic: Patents and Linux in Context Presenter: Keith Bergelt When: Thursday, 8th August 2013, 7pm Where: NC State Engineering Building II Room 1025, Centennial Campus Parking: The parking decks and Oval Drive street parking are free after 5pm Map: Google Maps Video: YouTube

Keith will talk about intellectual property as a reality that shapes the context for open source software, particularly when overlaid against trends in technologies such as mobile and cloud computing, provide the history of Open Invention Network and its licensee community, and discuss Linux Defenders and other opportunities for community members to contribute proactively for the benefit of open source software.

Keith Bergelt is the chief executive officer of Open Invention Network® (OIN), the collaborative enterprise that enables innovation in open source and an increasingly vibrant ecosystem around Linux. In this capacity he is directly responsible for enabling, influencing and defending the integrity of the Linux ecosystem. Central to the achievement of his goals is the acquisition and transfer of patent rights designed to permit members of the Linux ecosystem to operate free of the threat of assertion and litigation from those whose business models are antithetical to innovation and global economic growth in information technology and computing.

July 11 meeting: Lightning Talks


Topic: Lightning Talks Presenter: TriLUG Community When: Thursday, 11th July 2013, 7pm Where: NEW LOCATION! Department of Electrical and Computer Engineering, NC State Engineering Building II Room 1021, Centennial Campus (just across the street from Red Hat) Parking: The parking decks are free after 5pm, and street parking on Oval Drive. Map: Google Maps Video: YouTube RSVP: EventBrite (You don't actually need to bring a ticket to attend. Getting one just helps us prepare for refreshments so nobody goes without pizza!)

We'll be putting the July meeting in the hands of the TriLUG community by holding a series of Lightning Talks. Lightning talks are short talks of about 5-15 minutes long that give the audience a taste of a topic rather than going into the great detail associated with formal presentations. If you've been working on a cool project lately or learned something cool about technology, you are qualified to present something!

If you have an idea for a talk, please pitch it on the TriLUG mailing list and the community will help you cultivate it into a presentation you can be proud of. Prepend your subject line with "LT:" to make it easy to find (ie subject = "LT: Using Inkscape"). The Steering Committee will then collate a list of the topics and speakers from the mailing list posts. There isn't a set theme yet, but we expect a theme will emerge from the discussions in the next couple of weeks.

  • Cracking Password Hashes (Slides) - Scott Miller
  • Booting Linux on EFI using rEFInd - Matthew Frazier
  • Electric Cars and Open Source Cars (Slides) - Jeremy Davis
  • Network testing with iperf (Slides) - Bill Farrow
  • Networking Tools (Slides) - William Chandler
  • Flashback - a better way to backup -Alan Porter
  • Open Source Ecological Solutions - Moustapha Barry
  • Ceph storage platform (Slides) - Jack Hill

Make sure your schedule allows for you to attend this special event. Also, spread the word to your fellow digerati and invite them to attend.

Please note that this meeting will be held at a new venue, so there will be some shifts in the usual schedule. NCSU does not permit food in its classrooms, so we are going to begin the meeting with a reception/networking over our usual pizza in the atrium of Engineering Building 2. At about 7:30 we'll move to 1021 to begin businesss, community announcements, and the presentation.
