Summary

First of all, we will be announcing the some Trilug News. Be there or be square!

About the talk, people use docker -- by itself, in a swarm, or behind kubernetes -- to do software as a service or something like that. But, is that all it can do? Can we use it for other applications when we are too lazy to build a full virtual machine or baremetal server? And, why should we do that?

Summary

Each year, TriLUG holds a special, unusual meeting.

Once again, we are planning on our traditional Science Fair. Come one, come all, and show off your latest toys!

As well, we would like a few suggestions for what we might serve. Should we go with our "traditional" pizza, or something else? How about a Pot Luck?

We hope to see you all on the 12th.

Summary

Razee.io is a collection of open source Kubernetes operators that allow us to deliver the dozens of workloads across the thousands of clusters that comprise the IBM Kubernetes Service (IKS). I'll describe the stages of continuous delivery evolution that lead us to create and publish these tools. I'll demonstrate how you can use razee.io to deliver workloads to your favorite Kubernetes cloud.

Summary

I recently wrote a "driver" to interface my Raspberry Pi to a bluetooth data acquisition board in Python. There are some interesting subtleties in talking to a device in Python that may be of interest to the beginner as well as the intermediate Linux user. This talk will cover some of the basics of how Bluetooth is implemented in Linux with Python.

Bio

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.

Summary

What are logs? What are metrics? A look into the challenges you face when building log aggregation pipelines, and how to build an operable and efficient pipeline at any scale. Also a collection of best practices for using metrics for health and alerting and optimizing both metrics and logs for successful observability.

Bio

Jack, a Senior Operations Engineer at 42Lines, has just shy of 20 years experience in Linux/UNIX system administration leading into the DevOps practices currently in use today. He's architected backend, scalable systems for universities with more than 100,000 users and companies with millions of users worldwide. The last several years he has focused on building and deploying telemetry based monitoring, alerting, and analysis tools such as Prometheus, Thanos, Grafana, and Graphite. Turns out that metrics can be quite powerful when used with best practices. Jack has always enjoyed math and has found his passion in working with time series data, statistical analysis, and in training others to get the best use of their metric data.

Breandan has been working in UNIX and Linux operations for almost 20 years. As a Senior Operations Engineer at 42Lines, he currently focuses on distributed systems and log aggregation at scale, building aggregation pipelines that handle hundreds of terabytes of log data a day. He has spent considerable time working for academic institutions and traveling internationally.

Summary

In this presentation, we will look at typical mistakes measuring or interpreting Linux Performance. Do you use LoadAvg to assess if your CPU is overloaded or Disk Utilization to see if your disks are overloaded? We will look into these and a number of other metrics which are often misunderstood and/or misused as well as provide suggestions of better ways to measure Linux Performance.

Summer is here, and soon we will begin the hurricane season. While we wait, how about if we have two presentations for the price of one?

Summary

"On the sorry state of modern programming languages and other rants, with some surprises" by Mark Sidell

I begin by explaining why I hate all modern programming languages, explore alternative, and then declare that PDP-8 assembly is really the best choice. Next, I briefly explore the PDP-8 instruction set, but switch gears to what every programmer really wants to do -- make lights blink. I demo blinkenlights on the Raspberry Pi, Arduino, and finally on a replica of a PDP-8. Of course, the only thing the audience knows at the beginning is the title of the talk.

Bio

Mark started his career designing speech recognition hardware at a startup in Cambridge, MA, and then at Dragon Systems when it was a five-person company in a living room. Later he wrote the Forte Agent Usenet newsreader, which some folks might remember. Today he does software at Viasat, focusing mainly on the AWS cloud.

Summary

"Random Thoughts on Programming Languages" by Jack Hill

It is supposed to be random, so the summary will be up to whatever your mind makes it be. Focus on Clojure, Go, Haskell, Rust, or Scheme.

Bio

Jack is on the Systems team at Duke University Libraries, and is passionate about Free software, storage, and functional programming. When not thinking about computers, he cares about Catholicism, trains, fountain pens, amateur radio, and ultimate (frisbee).
