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.

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.

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 Map: Google Maps Sponsor:Apex Systems Video: YouTube

Synopsis: 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.

Bio: 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.

Synopsis: What is Katello and how can it help me?

Katello (http://katello.org/) is a systems lifecycle management plugin to Foreman (http://theforeman.org/), and the next-generation replacement for the very-popular Spacewalk (http://spacewalk.redhat.com/). Katello adds software and subscription management capabilities to Foreman, which itself offers configuration management and provisioning via Puppet.

Katello might be useful to you if: - you are a novice to advanced system administrator - you are managing 10 to 10,000+ hosts - you want to control the content available to hosts based on rules you define - you want to provision hosts using the content you are managing - you want hosts to consume content that you are managing - you would like to interact with the system using a web UI, CLI or REST API

This presentation will cover topics such as managing the lifecycle of content, provisioning systems with that content and enabling existing systems to consume content.

Bio: Brad Buckingham is a Principal Software Enginner at Red Hat working on the Katello open source project, and previously on Spacewalk. He first began working on Linux around 1993 and since then has been developing applications to run on Linux and Unix across multiple domains (e.g data acquisition systems at NASA, telecommunications and for the enterprise).

Sponsor: Red Hat Red Hat is the world's leading provider of open source software solutions, using a community-powered approach to reliable and high-performing cloud, Linux, middleware, storage and virtualization technologies.
