July 14 meeting - AirPrint and mDNS

When: Thursday, July 14th, 7pm
Where: Red Hat HQ, NCSU Centennial Campus
Map: http://www.redhat.com/about/contact/ww/americas/raleigh.html

Zero configuration networking allows machines on a network to publish their capabilities for others to use, without requiring an administrator to specifically list those services in a directory.

TriLUG member Jym Williams-Zavada will be taking a look at two zeroconf services, AirPrint and mDNS. Both of these technologies were introduced by Apple, and now they are gaining support on other platforms as well.

AirPrint allows you to publish the presence of a printer, and then allow devices to print to it. The quintessential use case is printing from an iPhone or iPad.

Similarly, mDNS publishes the presence of other services on a network. Perhaps you have a public shared drive where you store your music.

Jym will show us how to configure both of these services on a Linux machine.

Jym Williams-Zavada has been a member of TriLUG since he moved to NC from Syracuse, where he was active in SyrLUG. He served on the TriLUG steering committee last year. Jym currently works as a system administrator at Shodor in Durham.

June 9 meeting - Android and openness

When: Thursday, June 9th, 7pm
Where: Red Hat HQ, NCSU Centennial Campus
Map: http://www.redhat.com/about/contact/ww/americas/raleigh.html

Android has taken the mobile market by storm, in part due to its open source nature (did you know it is based on the Linux kernel?). However, Android development has had to walk a delicate line between developers demanding openness and the established mobile industry that prefers to lock everything down.

In this talk, Luke will introduce Android as a mobile development platform, discussing the architecture and development tools available, as well as the history of how Android has walked the line between open and closed.

Luke Meyer, web geek and open source zealot, started TriDroid, the Triangle Android Meetup, because no one else had done so yet when he wanted to start hacking for his G1 phone. He currently works technical support for SpringSource at VMware. Previously he worked as a web engineer at Red Hat.

Announcing the inaugural TriLUG survey!

Exciting times are at hand!

As one might guess from the subject of this announcement, the TriLUG Steering Committee is unleashing its first experiment in the realm of data and demographics. We have carefully crafted our inaugural online survey, one which we hope will reveal who our constituents are and how they feel about TriLUG.

Since we believe in open source and value your privacy, and thanks to the excellent LimeSurvey project, our survey is entirely hosted on TriLUG hardware. Your responses are anonymous and will not be shared with third parties. That said, please refrain from abusing your anonymity to the detriment of our efforts.

This is not an excessively long survey. However, you may want to set aside 15-20 minutes just to be safe. If you get interrupted, there is a button to save and resume later at the bottom of each question.

Though it should go without saying, survey participation is entirely voluntary. We don't know who you are, so no one will hold it against you if you roll your eyes and delete this message. But if you are willing to help TriLUG become the best LUG ever, follow the link below to begin...

 Take the TriLUG 2011 Official Survey

This survey will be active for approximately 30 days, so don't miss your chance to be heard. Shortly after it closes, we hope to publish a summary of the responses for all to see.

Any questions or concerns should be sent to the Steering Committee. Thank you in advance for your participation!

April 14 meeting: intro to iSCSI and cost effective NAS

Topic: A practical introduction to iSCSI and cost effective NAS solutions
Presenter: Jon Magrini
When: 7PM, Thursday April 14, 2011
Where: Red Hat Worldwide Headquarters
Permalink: http://trilug.org/2011-04-14/storage

Bio: Jon Magrini is a Red Hat TSE in the Storage SBR at Red Hat and joined their team a little over a year ago. His specialty is clustering, with a focus on storage related technologies. Jon's Linux experience started in the early 2000 era when he worked for Borland software and developed pluggable modules, using a pure java open-api for software products such as JBuilder and Together Control Center. His interest for storage started with employment at Red Hat and the purchase of his own EMC CLARiiON, which started a waterfall effect.

March 10 meeting - High Availability, Low Dollar Load Balancing

Synposis: True high availability load balancing traditionally involves specialized, expensive hardware and software. However, you can build advanced, high availability configurations without a single point of failure using nothing but open source tools and commodity hardware. This talk will include a discussion of several tools, configurations, and advantages and disadvantages thereof. All tools involved are 100% free and open source. As a bonus topic, Simon will tell you how to use open source load balancing tools to IPv6-enable your IPv4-only infrastructure with minimal risk, time and hassle.

About the Speaker: Simon Karpen is the system architect / wearer of many hats for VoiceThread, which provides a very powerful rich media asynchronous collaboration platform. He has also worked for the Shodor Education Foundation in the past, and is a current NCSU MBA student (class of May, 2011). Simon is a member of the NC*SA Steering Committee.
