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: 
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: 
City Center Deck, 429 S Wilmington St - use NE elevator to access Annex

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.

Topic: 
TARPN Off-The-Grid Text Messaging
Presenter: 
Tadd Torborg
When: 
Thursday, 8 June 2017 - 7:00pm to 9:00pm
Where: 
The Frontier, 800 Park Offices Drive, Durham, NC
Parking: 
Parking is free, onsite

Summary
At the June TriLUG meeting I will show what a $150 starter TARPN station looks like as well as a multiple-link network node used to tie several destinations into a single Raspberry PI. I’ll bring some sample antennas. I may even be able to show communications from a station set up at the meeting into our existing 42 mile wide network.

In 2014 I started creating the TARPN web site to promote a technology, philosophy, and system for promoting and building a scalable digital communications system with education as a major purposes and with the goal of having Raspberry PI users communicate over distances of hundreds of miles by stepping through intermediary stations, all built by hobbyist volunteers using equipment located in our homes or at sites the participants control.
TARPN’s buzz-phrase is "off-the-grid text messaging". We communicate entirely on hobbyist controlled networks, mostly located in our homes. Internet is neither required nor desired. The challenge and reward is doing it on our own. This also gets us some extreme educational opportunities. See our web site at TARPN.NET

Tadd Torborg is a Firmware Engineer presently consulting to a startup company in Austin TX from an office at First Flight in RTP.

We’re using WiFi and “UWB” transceivers for indoor asset tracking. I have been a small systems microprocessor programmer since 1982 starting with the RCA 1802 CPU for E-Com in Stirling New Jersey. My first microprocessor programming job and my first packet radio project were both in 1982 at E-Com where they were using packetized messages sent and received on CATV lines. I’ve been working in digital radio communications for about half of my working life and in microprocessor programming for bare metal systems for 30 of the past 35 years. I’ve been using Amateur Radio for digital radio communications between computers since 1981.

My first computer KIM1 by MOS Technologies uses 6502 CPU, same as Apple 1 and Apple 2 computers. I bought this in 1978 for $190 + $30 for a plastic box.
I wrote a touch tone decoder, morse code sender, telephone pulse dialer, a couple of games and learned how to do memory busses. Coding was involved writing separate functions in memory, with space in between for expansion room. Code was entered using HEXidecimal machine instructions.
The code space allowed for about 400 instructions in 1K of RAM. Watch out, the stack, limited to 256 bytes, wants to gobble up part of that.

My hobby is Amateur Radio. My FCC issued Amateur Radio callsign is KA2DEW issued in 1979 when I lived in Mendham New Jersey. I’ve lived in Wake County for 10 years, married with two adult children, and I’m 57 years old.

Topic: 
Home Brew Lab Hack Night
Presenter: 
Mike Canada
When: 
Thursday, 18 May 2017 - 7:00pm to 9:00pm
Where: 
Caktus Group, 108 Morris St, Suite 2 Durham, NC (Next to Bullseye Bicycle)
Parking: 
Street parking

Bring your system down to Caktus Group and let Mike help guide you in how to set up your own Home Brew Lab. From installing the hypervisor, to spinning up VMs and maybe configuring a little virtual infrastructure, he'll be on hand to help kickstart your setup.

Note that you should bring a reasonably powerful system if you want to set up much more than a trivial lab.

Topic: 
Home Brew Lab
Presenter: 
Mike Canada
When: 
Thursday, 11 May 2017 - 7:00pm to 9:00pm
Where: 
The Frontier, 800 Park Offices Drive, Durham, NC
Parking: 
Parking is free, onsite

Note
We will be holding our annual Steering Committee elections at the very start of the meeting.

Summary
In this talk, I will cover how you can create your very own lab for both testing and learning new platforms using freely available software. I want to share with everyone a way that you can have your very own test lab at home for little to no money. With this project, you can brew your own lab at home or work with only one "server" allowing you to test many OSes and networking configurations. I will discuss topics including: Why do a Home Brew Lab? What kind of hardware to you need? What virtualization platform? What kind of networking? I will also provide ideas on how to obtain hardware at reduced and sometimes no cost. I will present methods of acquiring various type of OS and software including VMWare, KVM, and Hyper-V. I will also discuss the implications of the licensing for each product.
