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.

Topic: 
Lightning Talks
Presenter: 
You!
When: 
Thursday, 9 November 2017 - 7:00pm to 9:00pm
Where: 
NCSU College of Textiles, 1020 Main Campus Dr., Room 2207
Parking: 
Underground parking deck immediately adjacent to the building (see map).

We have a lot of really talented members, who do a lot of really interesting things. Come on down and share some of those things with your fellow members! Let us see your hobby hacks, your nifty shell incantations, or the latest tricks you've managed to make your Raspberry Pi or Arduino do. This doesn't have to be long - a few minutes is more than sufficient.

Note that this could also be a nice way to introduce whatever demo you plan to bring to the December Holiday Social - whet the appetite for more, as it were.

The Sign-Up Form is up and ready for entries!

Talks:

  • Presenter: Brian Gerard
    Topic: Creating a Self-Installing Package
    Summary:I'll show a method for creating a self-installing package out of a git repo using gmake and a little scripting glue. While it's more a neat trick than a best practice, it has come in handy at work as a stopgap while we get more battle-hardened solutions in place.
  • Presenter: Michael Hrivnak
    Topic: The Lounge IRC client
    Summary:The Lounge is a web-based IRC client, and I love using it.
  • Presenter: Bill Farrow
    Topic: Building Debian packages for ARM with Docker and QEMU
    Summary: Building Debian packages is fun, but building them on a slow embedded system is not fun. Cross compiling is messy and complicated. Using the superpowers of Docker and QEMU you can build those packages on your screaming 16 core x86_64 desktop in no time at all.
  • Presenter: Barry Peddycord III
    Topic: Mastodon: The OSS Alternative to Twitter
    Summary: Learn about Mastodon: A modern, open source implementation of the GNU Social protocol for microblogging.
  • Presenter: Dwain Sims
    Topic: Rapidly Changing Storage Formats
    Summary: I will take a really quick walk through the rapidly changing world of storage form factors, and make some predictions!
Topic: 
A Look at Atomic Host and Linux Containers
Presenter: 
Joe Brockmeier
When: 
Thursday, 12 October 2017 - 6:45pm to 9:00pm
Where: 
NCSU College of Textiles, 1020 Main Campus Dr., Room 2207
Parking:

Project Atomic

Video: YouTube

Summary:
If you pay attention to tech news at all, you're probably hearing a lot about Linux containers. In this talk, we'll take a look at what's behind the hype and dive into what containers are really good for, what they are, and the best ways to start getting your feet wet where it makes sense to use containers. This will include a look at Atomic Host, an opinionated take on Fedora, CentOS, or Red Hat Enterprise Linux designed strictly to run Linux containers and help organizations focus on applications inside the container.

Brockmeier has worked as the openSUSE Community Manager, is an Apache Software Foundation (ASF) member, and participates heavily in the Fedora Cloud Working Group.

Topic: 
Rethinking RAID
Presenter: 
Dwain Sims
When: 
Thursday, 14 September 2017 - 7:00pm to 9:00pm
Where: 
NCSU College of Textiles, 1020 Main Campus Dr., Room 2207
Parking: 
Underground parking deck immmediately adjacent to the building (see map).

Slides: Here

Note the venue - we are in our new location!

Summary
For those of us still configuring physical servers and storage, using RAID to ensure the availability of storage is part of our everyday jobs. But things are changing rapidly in the types of storage devices being used, as well as their characteristics. Standard RAID techniques may carry consequences that solution architects may not realize are present.

This talk will examine the beginnings of RAID, how we got to where we are at now, and some of the issues that currently exist with RAID. Alternate techniques (including open source solutions) can provide more resiliency with fewer gotchas. There will also be a quick tutorial on "fio", the flexible I/O tester.

Topic: 
Open Data
Presenter: 
Jason Hare
When: 
Thursday, 10 August 2017 - 7:00pm to 9:00pm
Where: 
Red Hat Annex, 190 E Davie St, Raleigh, NC 27601
Parking:

NOTE the venue change! We're at the Red Hat Annex, where we have held our last couple of Holiday Parties, in downtown Raleigh.

Summary
Conflation between open source, open data and open government has been problematic in fitting open data related open source projects to meaningful outcomes. Jason Hare will discuss data management and the link between open data and performance management and measurement. To do this Jason will run through a survey of some of the open source technologies used to manage data and create visualizations. Jason will also discuss issues around open data and its adoption by public sector agencies in the Triangle and how civic tech groups are adding value to open data programs through open source efforts.

Topic: 
Multi-Service Applications in Kubernetes
Presenter: 
Michael Hrivnak
When: 
Thursday, 13 July 2017 - 7:00pm to 9:00pm
Where: 
The Frontier, 800 Park Offices Drive, Durham, NC
Parking: 
Parking is free, onsite

Summary
This session will detail how to deploy a multi-service application in Kubernetes, using Pulp as the example. Pulp is a multi-service web application that manages repositories of content, such as software packages, and makes it available for installation. With a REST API, async worker processes, a scheduler process, and a service to curate job queues, Pulp is a natural fit for the orchestration provided by Kubernetes.

In this session, you will learn:

  • How to deploy a multi-service application in Kubernetes
  • How to share persistent storage across multiple services
  • How to scale individual services to meet changing load
  • How to manage shared configuration and secrets for a "pre-docker" app
    that was not designed for container deployment

Bio
Michael Hrivnak is a Principal Software Engineer at Red Hat and Team Lead for the Pulp Project. With strong experience in both software and systems engineering, he is excited to be writing software for systems engineers. Michael is passionate about open source software, live music, general aviation, and reducing energy consumption.
