This presentation will be a panel discussion about how to give a technical presentation.

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.

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

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!)"



Meeting 13 November: The State of Open Source Bookkeeping

Topic: The State of Open Source Bookkeeping
Presenter: Eric Leary
When: Thursday, 13th November 2014, 7pm (pizza from 6.45pm)
Where: NC State Engineering Building I Room 1007, Centennial Campus
Parking: The parking decks and Oval Drive street parking are free after 5pm

The domain of financial record keeping could greatly benefit from new open source projects that provide accounting software solutions for the small to medium enterprise. The current offerings don't fulfill contemporary requirements, are often buggy and moribund in the maintenance of the code base, or are intractable to implement without extensive commitment from third party developers.

Quickbooks Online and Xero accounting will be held up as representative targets from the commercial world that the open source community should pursue with competitive products and frameworks. The talk will delve into GnuCash and other open source offerings, showing their strengths and weaknesses in today's world.

Eric is not an accountant, he is a bookkeeper. He has been using Quickbooks for over 17 years in a wide range of industries, but he is drawn to Python and Open Source for some strange reason. I think he would prefer to give it all up and go back to theater set design, but such is life.
