We are here! Thanks to the gracious people running it, we have a table at the All Things Open this year. I have to be honest, it has been a humbling experience.

First we need to get some swag made. Specifically, stickers because everyone loves stickers! Ours is different from everyone else here because we did put QR codes on the part of the sticker you do not peel off. We should have made more because as of right now (Monday 21 October 11:44am) we are down to 20.

We also made a ton of handouts.

Sunday was setup day, and and the first was finding out our table location.

You might recognize the tux sign; it is the same one we take to every meeting. With some of the 3Dtuxes, thanks to Brian Henning, for good measure.

We will be updating (or editing) this as the event takes place. If you are at ATO, please come by our desk and say hi.

And, we would like to thank the folks at All Things Open for inviting us to come and offering us a table. We do hope we will be able to be there again next year.

CANCELLED October 11 - An introduction to the Drupal CMS


Hurricane: 2 | Trilug: 0

Our timing has not been good lately. The very day we are supposed to have another meeting a (degraded) hurricane decided to come this way. Since there is concern about not only winds but also flooding (this is NC after all), we the steering committee decided it was best to cancel the meeting.

I hope for the november meeting we will enjoy a hurricane-free atmosphere.

I do apologize to those who were looking forward to hear this great speaker talk. But we do not want to have him (and you!) call us later from Oz.

We'll keep it interactive -- so ask about any subject that you wish expanded. We'll also look at a quick tutorial on getting Drupal set up locally, so if you're interested, bring a laptop. We have WiFi service in our meeting.

Some of the things we'll cover, time permitting:

  • Drupal - what is it - how is it used?
  • Drupal's past, present and future
  • Drupal 8 (current version) vs previous versions
  • Drupal vs. Wordpress (because you have to)
  • Deployment and maintenance tactics and best practices
  • How to spin up a local instance
  • Performance optimization
  • Automated testing

Because of the hurricane, NCSU is closed until Monday. So we will have to cancel this month's meeting.

Apologies for all the members who were looking forward for a movie night.

Revolution OS is a 2001 documentary film that traces the twenty-year history of GNU, Linux, open source, and the free software movement (https://en.wikipedia.org/wiki/Revolution_OS). It features interviews of some heavyweights in the Open Source community like Richard Stallman, Michael Tiemann, and Linus Torvalds. No Macintosh Computers were harmed during the production of this movie.

August 9 - Storage Topologies, including ZFS and btrfs


Topic: Storage Topologies, including ZFS and btrfs
Presenter: Jim Salter
When: Thursday, 9 August 2018 - 6:45pm to 9:00pm

Ever been confused about the difference between IOPS and throughput? Why the pundits are saying "RAID5 is dead"? Or how various RAID topologies work? Come to the TriLUG meeting August 9th, and Jim Salter will cover performance, redundancy, and storage efficiency for all sorts of storage topologies, along with how you'd measure them and why you'd care. We'll start out simple with a single disk, then move onwards and upwards through traditional RAID configurations, and then move on to ZFS and btrfs. Wear your nerd hat, and if you have questions, be ready to ask 'em.

He’s the author of the Sanoid hyperconverged infrastructure project.

It comes as no surprise that cloud migration and micro-service architectures are all the rage right now. In fact, one of the most satisfying parts of my job is spinning up infrastructure, analyzing and figuring out how to get all the pieces of service layers to play nicely together in the cloud. As we aim for cloud-native design, the idea of serverless applications become more and more alluring.

In this talk, I would like to discuss some of the tools available to us with which we can build serverless applications. Additionally, I would like to break down a simple application into its pieces and examine the role of each AWS service offering and how we wired them together. We will discuss service responsibilities and configuration of API Gateway, Lambda, S3, DynamoDB, SNS, SQS and more. Time permitting, we will also discuss the use of Cloud Formation to orchestrate and deploy a serverless application.

June 14 - Optimizing MySQL performance


Topic: Optimizing MySQL performance
Presenter: Peter Zaitsev, CEO of Percona
When: Thursday, 14 Jun 2018 - 6:45pm to 9:00pm

Optimizing MySQL performance and troubleshooting MySQL problems are two of the most critical and challenging tasks for MySQL DBAs. The databases powering your applications need to be able to handle heavy traffic loads while remaining responsive and stable so that you can deliver an excellent user experience. Further, DBAs are also expected to find cost-efficient means of solving these issues.

In this presentation, we will discuss how you can optimize and troubleshoot MySQL performance and demonstrate how Percona Monitoring and Management (PMM) enables you to solve these challenges using free and open source software. We will look at specific, common MySQL problems and review the essential components in PMM that allow you to diagnose and resolve them.

Peter co-founded Percona in 2006, assuming the role of CEO. Percona helps companies of all sizes maximize their success with MySQL. Percona was named to the Inc. 5000 in 2013. Peter was an early employee at MySQL AB, eventually leading the company's High Performance Group. A serial entrepreneur, Peter co-founded his first startup while attending Moscow State University where he majored in Computer Science. As CEO of Percona, Peter enjoys mixing business leadership with hands on technical expertise. Peter is the co-author of High Performance MySQL published by O’Reilly, one of the most popular books on MySQL performance. Peter blogs regularly on MySQLPerformanceBlog.com and speaks frequently at conferences. Peter lives in North Carolina with his wife and two children. In his spare time, Peter enjoys travel and spending time outdoors.

May 10 - IoT, Linux and the Raspberry Pi


Topic: IoT, Linux and the Raspberry Pi

Getting started with any IoT project can be a little daunting. Whether you are a beginner or and experienced embedded systems developer, there are always little parts of any project that could and should go smoother. This talk will focus on setting up the Raspberry Pi as a headless mobile device, configuring the digital IO pins on the Pi, taking analog signals, and then transmitting the data through LoRa, a Longe Range low power wireless protocol to a server on the net or in the cloud.

Dr. Jasper has been interested in real-time data acquisition and control since his undergraduate days when he measured the variation the earth’s gravity due to the tides. Although he has worked in the aerospace industry designing spacecraft altitude and control systems, he currently designs data acquisition and control systems for textile processes. His research interests include measurement and control of dyeing, plasma textiles for nanoparticle filtration, and writing Linux device drivers which can be found at https://github.com/wjasper/Linux_Drivers. In 2014 he was the recipient of a Fulbright grant in engineering education to promote study abroad for undergraduate textile engineers.
