Work on a personal project, hone your skills, or try something you learned about at a recent meeting (playing with "perf", anyone?). While you're at it, help us maintain the TriLUG infrastructure.

Our primary infrastructure objectives for this month's hack night will be setting up backups for pilot and discussing the next incarnation of TriLUG infrastructure; we would love to get your help and input on those!

Topic: Performance Analysis Presenter: Jeremy Eder When: Thursday, 12th March 2015, 7pm - 9pm (6:45pm for pizza) Where: NC State Engineering Building II Room 1021, Centennial Campus Parking: The parking decks and Oval Drive street parking are free after 5pm Map: Google Maps Video: YouTube Slides: http://people.redhat.com/jeder/201503-trilug.pdf

Synopsis: Jeremy will provide an overview of how the Performance Engineering group at Red Hat approaches performance analysis, show specific examples of testing methods that produced interesting results, and show how they are able to performance-tune infrastructure in the field using tools like tuned.

You will leave with a new appreciation for how many knobs and levers are available in the Linux kernel, and understanding how a practical approach to performance tuning can have a big impact on every-day deployments.

Bio: Jeremy Eder is a Principal Software Engineer and Network Performance Lead at Red Hat Inc, where he specializes in measurement and analysis of kernel-related performance metrics, and using that analysis to guide performance-tuning of real-world infrastructure.

Overview: In the fine tradition of the BarCamp Un-Conferences, we're having an Un-Meeting!

BarCamps ... are open, participatory workshop-events, the content of which is provided by participants. - Wikipedia

We are looking to have a handful of topics (suggestion form below), each of which should be well suited for a 10-15 minute mini-panel. On the night of the meeting, there will be print outs of each suggestion, with space to place a mark for whether you have something to say about it, or want to learn about it - or both. You can also sign up to be the "driver" for the topic. We will then pick the most popular topics to go through in sequence, doing a group demo/panel on each.

The driver for each topic will be the "hands on the keyboard" and kick things off by showcasing some tip, trick, best practice, etc on that topic. Each of the other panel members can then share their own favorite points, and we'll end each topic with some brief Q&A from the audience.

Topic Suggestions: Propose a topic you're interested in. Pick something that will lend itself well to discussion, and is narrow enough to be one of a handful for the evening. Submit your idea via the Suggestion Form.

Bio: Our speaker this month is you! This is meant to be a highly participatory event. Vote for topics you find interesting enough that you want to actively contribute to the dialog about them. Ask questions, give us your favorite tips and tricks, etc.

Proposed Topics

1. Useful Vim Plugins and How To Manage Them There are a few really good Vim plugins that make some common tasks a lot easier, if not downright enjoyable. I'll demonstrate a couple of them, and show one that makes managing vim plugins dead simple. Then share your favorites! http://vimawesome.com/ Demo github link: https://github.com/briangerard/vundle-and-vim-plugins-demo Aaron's github link: https://github.com/aschrab/dotfiles/tree/master/vim
2. MythTV "Linux in your living room": Do you run MythTV ? Tell us what frontend hardware you have ? Want to share a cool add-on or remote control ? https://www.mythtv.org
3. Github Flow Using pull requests, web hooks, and code review to avoid breaking the build https://github.com
4. Linux File/Directory Permissions and Filesystem Concepts Per newcomer request, let's go through all the permission settings on files and directories, and what they all mean. If we have time in the slot, we can also explore some fundamental filesystem concepts (inodes, superblocks, etc). http://tldp.org/LDP/intro-linux/html/sect_03_04.html Demo github link: https://github.com/briangerard/linux-permissions-demo

Topic: Improve your Editing Life with Vim Presenter: Jack Hill When: Thursday, 8th January 2015, 7pm (pizza from 6.45pm) Where: NC State Engineering Building 2 Room 1021, Centennial Campus Parking: The parking decks and Oval Drive street parking are free after 5pm Map: Google Maps Slides: Jack's Slides PDF or git repo. Full Screen Capture (OGV) of the presentation. Video: YouTube

Synopsis: I spend a large fraction of my time editing text, and am always on the lookout for things that will make the experience more enjoyable. In this talk, we will take a tour of the vim editor from how to use it and straight forward configuration options to arbitrary programming and scripting. While investigating these features, we will look at then through the lens of how they change your daily editing lives. There are, of course, other editors, and we will take a lightning tour of the other options.

Free Parking is available in the Red Hat Building as long as you enter after 7pm. This parking lot has designated Accessible Parking spaces and elevators down to the main lobby. On street parking is free after 6pm.

Please RSVP using the above form so we can pre-authorize building security. This will also enable us to budget food and space. Food will be catered from Neomonde, as well as side dishes and treats contributed by our members.

We do not have permission to have alcohol at the Red Hat building, so please don't bring any.

Demos Share your passion by bringing a project or product to show off. As we get more demos we'll try to keep the list up to date! If you want some inspiration, have a look at the demos from previous years: 2013, 2012. If you would like to setup your demo early, please meet in the ground floor lobby at 6pm.

Refer back to this page to see the list of demos as they come in.

Linux Performance Monitoring Tools - William Cohen Will show some example uses of SystemTap, OProfile, perf, and Performance Co-Pilot to better understand system performance.

Raleigh Makerspace - Rebecca Cooley A few sample projects made at the Raleigh Makerspace (they're not very high tech) but they were made on the laser cutter or ShopBot.

My Everyday Stuff! - Dwain Sims I will show a couple of FOSS tools on Linux that I use everyday; gpodder and SimpleScan + a great cloud service - Dropbox. This is pretty mundane stuff, but it may give you some ideas.

WebcamStudio - Bill Farrow Live video mixing, streaming, and recording. We use this software to record TriLUG presentations. The demo will show how to use multiple cameras, layering, transparency, and live streaming to Skype or Hangouts using the v4l2 loopback device driver. Developers wanted.

OpenWRT - Bill Farrow A live demo of OpenWRT running on a TP-Link TL-WR1043ND router, and a short demonstration of the build system that goes with it.

Open Source Music - Jeremy Davis, Ken MacKenzie, Alan Porter, Brian Cottingham Linux Music Software and Creative Commons Music

Chit Channel - Wes Garrison "Thermal printer that works over the 3G wireless network that allows sending ""chits"" for fulfillment, sending confirmation of receipt to a server via 3G, and notification of completion to a server. We're using it to send food order tickets to our restaurants, get confirmation that they received the order, and get notification when the food is ready without human intervention. I'd like to know if anyone has other ideas for its application outside of food (ie. this would be perfect for ordering unobtanium candle holders!)"
