Welcome to the TriLUG home page. We are a LUG dedicated to the Triangle area including Durham, Raleigh, Chapel Hill, and Research Triangle Park. This site, along with our wiki, will enable you to keep abreast of TriLUG information (meetings, events, news), and to communicate with local Linux and FOSS (Free and Open Source) enthusiasts.

The primary modes of interacting with us: mailing list, IRC, or coming to the monthly meetings.

Abstract:

Desktop 3D printing has become fairly popular in the last few years,
and affordable printers are flooding the market. But why buy a
difficult to hack black box when you could spend weeks
sourcing/printing parts, crimping a a bunch of wires, and calibrating a
fully open design from the RepRap project?

Aside from the freedom that comes from building your own libre hardware
printer, building your own has many advantages that make the effort
worth it. Want dual extrusion? Triple, quadruple extrusion even? Or how
about pushing the limits by printing clay or icing? Perhaps you'd like
a tiny but super fast printer, one you could fold up and fit into a
backpack, or a printer with a meter of build height. With a libre
hardware printer, you can do all of this -- and far more affordably
than purchasing or modifying a closed printer platform.

This talk will cover the advantages (and disadvantages) of building a
libre hardware printer with a focus on the popular RepRap Prusa i3
family. Finding the community, selecting one of dozens of designs,
sourcing components, and building a printer from scratch can be a
harrowing experience -- this talk should provide some orientation in
the chaos and make the process easier.

The talk will also cover using a 3D printer with 100% Free Software on
GNU/Linux, from designing models (including the printer itself!) to the
microcontroller running the printer.

Bio:

Clinton Ebadi is a kilt-wearing, cat-loving, Free Software
enthusiast. He's spent most of the last decade volunteering for the
Internet Hosting Cooperative and learning way more than anyone should
know about OpenAFS. After picking up an Arduino last year to make a few
LED strips blink, he found himself borrowing a friend's 3D printer a
few months later, and ended up hooked on hardware hacking.

Topic: 
Openshift 3 and the next generation of PaaS
Presenter: 
Clayton Coleman
When: 
Thursday, 10 March 2016 - 7:00pm to 9:00pm
Where: 
Bandwidth, Venture III, 900 Main Campus Dr, Raleigh, NC 27606
Parking: 
Venture Center Deck, adjacent to Venture III (visitor spaces are unrestricted after 5pm)

Clayton Coleman is architect and engineer on cloud orchestration and
containers at Red Hat, in charge of both technical direction for
Kubernetes and OpenShift (Red Hat's platform as a service built on top
of Kubernetes) as well as the broader container and container content
efforts at Red Hat. Clayton is one of the top contributors to both
Kubernetes and OpenShift and has been involved in many projects in the
container, platform-as-a-service, and ci/cd ecosystem over the last
four years. He enjoys sleeping, but rarely has time to do it anymore.

Abstract:

Containers, Microservices, Continuous Integration and Deployment, and
DevOps are the buzzwords of the day. But how do they actually help
make it easier to build and run software? How do
container-as-a-service systems like Kubernetes, Mesos, or Docker Swarm
change how software is deployed?

In this talk I'll cover how all of
these topics come together, how they can benefit developers and
operators, and how we've built a platform (OpenShift) that supports,
exposes, and safeguards that flexibility and power for devs AND ops.
I'll do an overview of the features and patterns in OpenShift that
make it easy to build and deploy applications, with a quick demo of
how it puts Docker containers to work in a cluster for local and
remote development.

Since OpenShift is built on top of Kubernetes,
I'll also describe how Kubernetes was built to solve Google-scale
problems and how even the humblest local web application can benefit
from those patterns.

Virtualize Our TriLUG Server!

The focus of this week's hack night we be to get a pilot (our current physical server) running as a VM on the new machine. Jmainguy has already copied over a disk image, so our tasks will be to verify that we are happy with the host configuration, to boot the pilot VM and verify that services (ssh, http, mail) are working properly, and to configure any proxying from the host to VM that is needed. If we are successful in this, we can draft a plan for swapping out the current pilot for the new VM server.

Come join us for some intellectual socializing and hacking for a great cause!

Lightning Talks
Presenter: 
TriLUG Members
When: 
Thursday, 11 February 2016 - 7:00pm to 9:00pm
Where: 
Bandwidth, Venture III, 900 Main Campus Dr, Raleigh, NC 27606
Parking:

We all know the TriLUG community is an infinite pool of enabling wisdom. Now it is time to tap into the intellectual resources of the group. Our next meeting will be all about sharing your ideas via Lightning Talks. The ultimate goal is knowledge transfer and maximum participation is required to make it awesome.

You will have approximately 10 minutes to engage the audience on a topic of your choice. You can prep slides for presentation or you can lead a group discussion.

Respond to the mailing list with your topic and we will reserve your time, first come first serve.

Topic 1: A lightning tour of Haskell, a lazy, functional programming language with a rich type
Presenter: Jack Hill

Topic 2: Sound Reinforcement 101, For Software People
Presenter: Matthew Frazier

Linux is excellent for audio work, but this won't cover too much of the
software side. This talk is more for those who are coming at sound
reinforcement from the software side, and getting tripped up when audio
signals behave differently than software people tend to expect. (Like
me, when I first started getting involved with the production crew at
church.)

Depending on how much I can pack into 10 minutes, we'll cover the nature
of sound, how it gets carried in both analog and digital forms, what all
the weird equipment you see sound engineers carrying around does, and
how to finagle sound into the format you want when you're hooking cables
together.

Topic 3: Demo a Minecraft Server running on a Raspberry Pi 2
Presenter: Emmett Miller (age 6) and Scott Miller

Here is a teaser slide: http://i.imgur.com/tgfi5Sd.png

Topic 4: Migrating WordPress snapshots within OpenShift
Presenter: Donald Frustaglio

Topic 5: Advanced use of LibreOffice
Presenter: Jeremy Davis

For two years I have used LibreOffice to publish the Triangle Career Development Newsletter. The relational database known as LibreOffice Base is the primary workhorse of the operation, which I use to gather information from over 100 websites. Once I capture all the data for upcoming events, a set of queries sorts and organizes the data then concatenates the results with HTML to create a nicely formatted newsletter ready to publish. One step of the process also involves LibreOffice Calc with a few hefty formulas to zip everything together. I will walk you through the process. The goal of this talk is to demonstrate the integrity and advanced capabilities of LibreOffice.

Virtualize Our Existing Server
When: 
Thursday, 21 January 2016 - 7:00pm to 9:00pm
Where: 
Bandwidth, Venture III, 900 Main Campus Dr, Raleigh, NC 27606
Parking: 
Venture Center Deck, adjacent to Venture III (visitor spaces are unrestricted after 5pm)

After months of hard work and phone tag by TriLUG sysadmins and volunteers, our new server, Moya, has been racked and installed in temporary housing! (Thanks to MetaMetrics for providing the space!) Our mission tonight is to convert our current server into a VM and get it running on the new server.

We will plan and coordinate our efforts in advance on the #trilug-sys IRC channel, on irc.freenode.net.
