Ring in the end of the year with TriLUG! Our annual Holiday Social is a great time of delicious food, cool demos, and socializing with other FOSS enthusiasts. This year, we're back at the Red Hat Annex in downtown Raleigh.

Demos of all kinds are welcome. It can be as simple as a cool piece of software you found on the Net, or as complicated as a 3-D printed electronic Halloween costume. Just let us know in the signup form (below).

This year's event will be a potluck, so bring something tasty along to share with your fellow TriLUG members!

Please fill out the quick sign-up form at the link below so we know if we need to fill in any culinary gaps (TriLUG will provide one or two dishes as well), and so we can make sure we have everything we need for the demos people are bringing.

RSVP here!

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!

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.

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.

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.

Bio Named one of the top 100 global influencers in Government Technology by Onalytica in 2017, Jason Hare is the Open Data Evangelist for OpenDataSoft. He has worked in the public sector and in data dissemination for most of his 25 year career. He serves in several organizations on the topic of data governance and open data: In the previous Presidential Administration, he was a frequent participant at the White House OSTP on the subjects of data quality and open data; he was a member of the White House OSTP Open Data Advisory Group; he is listed as an Open Data Expert on the World Bank's Open Data Tool Kit; he is an advisor on data governance to the Chemical Genome Project.

In 2013 he became a charter founder of the Open Data Institute Node for North Carolina. In the same year he became an Open Government Partnership (OGP) Delegate. He guest-blogs on the Open Government Partnership (OGP) website and is an Open Data Moderator for OpenSourceWay, the Red Hat Open Source Blog. He previously served as an advisor for the Open Data Working Group on behalf of the US OGP Civil Society Delegation. In the past he has also consulted with the Open Knowledge Foundation to help craft Ireland’s OGP submission and spent several years working on the ground with Irish Civil Society.

His Open Data projects include: The North Carolina Department of Commerce; Town of Chapel Hill; Durham City and County; Durham Public Schools; City of Raleigh; The City of Newark; The City of Cambridge; The City of Chelsea; Ireland’s Ministry of Reform; Colombia’s Ministry of Information and Communications; The Commonwealth of Puerto Rico; The Colorado Secretary of State’s Office.

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.

JUL-13 Meeting Announcements

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

Bio: 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.
