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.

When: 7PM, Thursday March 10, 2011

LUG Organizational Choices, Summary, 13 January 2011

Ten years ago, TriLUG started operating as a North Carolina non-profit
corporation, in order to accept hardware and monetary donations, in turn
re-donating to schools and local LUGs, acting as an incubator for promoting
Linux. Over time, Linux has become more mainstream, is accepted in the
business world, and even used at schools. TriLUG's mission has therefore
changed accordingly, to become more of an educational and social group for
technology and Open Source. Although we're still devoted to education and
outreach, our income and expenses are now related to pizza and meetings.

We are run by a Steering Committee whose membership changes by vote every
year in May. This committee is a group of volunteers, which mean the
committee members have a significantly limited amount of time and energy to
invest in running TriLUG. These two facts have led to a problem that TriLUG
now faces: Over time, the Steering Committee has focused it's efforts on
finding meeting speakers, donors, sponsors, and pizza; and maintaining our
online resources. The annual Steering Committee hand-offs and corporate
bureaucratic tasks have taken a back seat, to the point that we have been
delinquent in corporate paperwork and tax filings. In fact, we are just a
hair's breadth from losing our NC non-profit status and our Federal EIN.

TriLUG is now faced with a decision, upon which we must vote. We must
choose between one of two options.

Do we want to keep the non-profit corporate status which we've not really
used nor needed as of late? If we choose this option, it means that we MUST
spend the time and energy (and possibly even money) required to dig
ourselves out of a deep paperwork hole in order to prove to the IRS and the
State of North Carolina that we desire and deserve to keep the status. In
order for this option to function, we must have volunteers (other than the
current Steering Committee) who will stand up to do the necessary backlog
work. In addition, future Steering Committees MUST be responsible for the
bureaucratic tasks necessary for maintaining the non-profit corporate
status.

On the other hand, do we opt to dissolve TriLUG as a corporation, and become
an informal user group, handling money for pizza and speakers by using a DBA
bank account? This choice allows our current and future Steering Committees
to focus on providing speakers and pizza for meetings, and maintaining our
online resources, and frees us from worrying about meeting (or failing to
meet) corporate status requirements and performing the bureaucratic tasks
necessary to maintain a non-profit corporation.

As you consider the two choices, keep in mind that TriLUG has no current
need for non-profit corporate status, and that if we dissolve the
corporation now, at any time in the future we decide we need it, we can do what is
necessary then to re-incorporate. Also, consider that that at the
organizational meeting held in December to to discuss these matters, the
opinion of the majority of those attending was that we no longer need to be
a non-profit corporation. Finally, if we choose to keep our current
corporate status, it is imperative that those who choose this MUST stand up
and invest themselves in making it happen, or the choice WILL fail!

Members of TriLUG, for which option will you vote?

Organizational meeting - December 2

RESCHEDULED: Thursday, December 2, 2010

===============================================
For the last ten years, TriLUG has been operating as a NC non-profit corporation. In the early days, that structure was necessary because the LUG accepted donated hardware and re-donated it to schools and local LUG's. Since then, Linux has become more mainstream, accepted at corporations, and sometimes even used at schools. And in that time, TriLUG's mission has changed significantly, from being an incubator to more of an educational/technical/social group.

We're still devoted to education and outreach, promoting the use of free and open source software. However, as a business, the main income and expenses that we maintain are related to pizza and meetings.

We are entirely a volunteer-run organization. The Steering Committee members dedicate a lot of time to putting together quality programs for the members to learn from and enjoy. But there is also an overhead associated with running the LUG, and that involves paperwork, taxes and corporate filings.

Complicating matters is the fact that we are run by a collection of volunteers that changes every year in May. As the LUG's leadership undergoes its annual transition, we rely on effective hand-off's. Over time, the Steering Committee has been focused on tactical problems: where to find speakers, the price of pizza, finding donors and sponsors. In the meantime, some of the hand-off's and administrative tasks have taken a back seat. In fact, we have sometimes been delinquent in some of our administrative duties. This is not a recent problem... it has persisted for several years.

The meeting on 12/2 is for interested LUG members to discuss the current state of the LUG as an organization, and to brainstorm on possible changes that might make reduce our administrative overhead. We will not be planning meeting content or sysadmin duties or other tactical things -- this meeting is strategic. It's the boring stuff -- paying taxes, filing paperwork.

The "fun" stuff -- meetings, events, technical discussions, and so on -- will continue as normal.

DATE - Thursday, December 2, 2010
TIME - 7:00pm
LOCATION - RedHat HQ
ROOM - Cafeteria / Conference Room (where we normally meet)

November 11 meeting - Open Source Software for Musicians

Have you ever wanted to use your computer to record or play music?

In the old days, it took a studio full of equipment to produce and record music. But now, the required tools are much more affordable, and can easily fit into a home studio. There is a wide selection of very robust audio applications that run on standard PC hardware, and many of them are FREE ("free" as in "beer" -- but also as in "freedom").

Adam Drew has been playing and recording music on and with computers for 15 years. He was introduced to free and open source software when he went to work at Red Hat, where he does filesystem and cluster support.

Adam will show how anyone can use Linux-based software to produce studio-quality music. We'll look at what tools are available, how they work together, and we'll see and hear them in action. We'll also learn a bit about what community resources are available for learning more about the tools and technology so that you can get plugged in and start making music at home and get your questions answered when they come up.

Come join us for a lively toe-tapping demonstration!

Adam invites you to take a look at (and edit) his audio knowledgebase at http://LinkedListCorruption.com/audio-kbase . And if you need to reach him personally, send him an email at adam@LinkedListCorruption.com .

We would also like to thank our meeting sponsor, Uzoma Nwosu from the Signal Foundation (www.signalfest.com).

October 14 meeting - Apache ModSecurity

Time & Place: October 14, 2010, 7pm, at Red Hat HQ

Title: Introduction to ModSecurity, the Open Source Web Application Firewall

About this talk:

So your web server listens on port 80 and your firewall blocks most everything else. Secure, right? How about that port 80? Do you trust your application code? Is your server patched? Are your developers really more clever than the folks who want to break in? Is security even on the mind of your developers?

Our traditional firewalls (packet filters) may have narrowed the field to HTTP, but crackers and worms have responded by refocusing their efforts directly at HTTP. Worse yet, most packet filters think all HTTP requests look legitimate. What's your next line of defense?

This presentation introduces ModSecurity, a web application firewall (WAF). ModSecurity is open source, mature, stable, flexible, and updated frequently. It can run embedded in Apache or as a reverse proxy in front of any traditional web server. It is highly discriminating and it definitely understands HTTP at a deeper level than your packet filter.

Come learn how to get started with ModSecurity. You'll be glad that you did.

About the presenter:

Cristóbal Palmer, a long-time member of the TriLUG Steering Committee, just finished his MSIS at UNC Chapel Hill, where he is a Systems Administrator with ibiblio.org. He also works with Caktus Consulting Group, a local django development shop.
