The December meeting of the Central NH Linux User Group will be held as usual in Room 146 of the NHTI Library – details and directions can be found at http://www.centralug.org – and will feature David Berube presenting “Real World Experience with Large MySQL Deployments”
David recently attend the Percona Operations Day training covering real world howto’s on big MySQL deployments and will share what he’s learned.
About David: David is a principal at Berube Consulting. David Berube is a software developer, consultant, speaker, and writer. He is constantly researching, perfecting, and practicing his trade. He is a prolific writer, appearing in places such as Dr Dobbs Journal, Linux Magazine, IBM DeveloperWorks, PHP International Magazine, and many others. He speaks frequently, notably including his seminar series, “Making Money Using Open Source Software”. He authored the books “Practical Rails Gems” and “Practical Reporting with Ruby and Rails”, and co-authored the book “Practical Rails Plugins.” He is also a leader in the Open Source community. He was involved with the AmphetaDesk project, developing much of its Win32 GUI code.
Eighteen people attended the second ManchLUG (wiki, twitter) meeting, held at “Wings Your Way” on Elm Street in Manchester. Early attendees to the meeting enjoyed good food, beverages and camaraderie.
It’s never easy to summarize a maddog presentation . Maddog had a lot of interesting materials to cover, and provided a lot of depth and background to his main thesis. Briefly, Project Cauã is based in Brazil as the center of its first pilot and rollout, but intends to be worldwide. There’s a strong ethos of openness and transparency in hopes the project will be duplicated elsewhere. It is an effort to distribute computing power and internet connectivity to as many people as possible as cheaply as possibly, but using the power of capitalism and business to drive the project, rather than some completely free charitable model that would be trying to fight the entrenched interests. There seemed to be an emphasis on sustainability, both for the project and the world, and the principles of Open Software.
The infrastructure would consist of very-low-power (10-12 watts) mini-machines, a small fanless thin-client box with USB3 and gigabit ethernet connectivity, wired into large servers centralized in neighborhoods or apartment building basements. The machines would be manufactured as greenly as possible and built for long term service (6-10 years). Small businesses would be established and trained (cheaply over the internet and/or with DVDs) to service the machines. The thin clients would rent/lease for a target price of $6/month. To avoid vendor lockin or obsolescence, the thin client design would be open, designed by the University of São Paulo and distributed/licensed freely to the many SMT (Surface Mount Technology) assembly facilities available within Brazil (import duties of 100% on finished goods, versus a 6% surcharge on raw components, means that in-country assembly is economically feasible, driving local employment). The project intends to use the network to provide free metro-wide Wifi. Some vendors have expressed an interest in providing free internet band width in exchange for idle CPU power. There’s lots more to the project of course: finding the proper motivations to financial institutions to provide the seed money the many small startups will need, certifying and bonding the local computer experts, designing and integrating the hardware, software, networking, etc., but maddog only had a little over an hour to present. More can be learned at http://www.projectcaua.org and maddog promised he’d be further updating the site soon.
Thanks to maddog for the presentation, to Kenta Koga and Chip Marshall for coordinating the meeting, to Wings Your Way for the facilities and good food, and to all for attending and participating!
The topic of the month is Wikis. “Wiki Wiki!” is Hawaiian for “quick, quick!” and is a pattern of presenting a read-write web site. There are more variations and implementations than grains of sand in the universe. but we’ll look at a couple of them, specifically:
We’ll talk a little bit about the range of markup languages, the technology behind the wiki, the social and community aspects of how a wiki works (or doesn’t), and how Free/Open Source has played into the success of wikis.
Recommended Reading: “The Wiki Way, Quick Collaboration on the Web” by Ward Cunningham (inventor of the wiki) and Bo Leuf, Addison-Wesley, 2001, ISBN 0-201-71499-X and http://wiki.org/. We’ll have a copy there for your browsing.
Comments from other members suggest we might also want to look at:
Wikipedia’s entry on Wikis: http://en.wikipedia.org/wiki/Wiki_software and
a list of software with comparisons: http://en.wikipedia.org/wiki/Comparison_of_wikis
My most active Wiki experience: http://fox.wikis.com (Not open source, either in implementations nor base language).
If it’s Thursday, it’s LUG-Day. Tonight: Tim Wessels demos Kablink open collaboration at MonadLUG: http://is.gd/zO4S – note unusual location.
Kablink looks promising: a synchronizing folder feature, document management, and conferencing software. It appears to be (or have been) the Open Source version of Novell’s SiteScape, at least a portion of which came from the 2008 acquisition of SiteScape, Inc., a company that traces its roots back to Clock Tower Place in Maynard, Massachusetts and the Alta Vista folks.
Looking forward to the presentation!
