NHRuby, August 20th, The Rosa Restaurant

By on August 16, 2009 in LAMP, OpenSource, Ruby, Web Development

Some of the best user group meetings I have attended have been those with the most relaxed format, where the group pretty much steers the conversation to whatever is most interesting to them.While the formal presentations by experts are great for getting some deep and rich information across, the wide-ranging discussions of an informal meeting can stretch the breadth of your knowledge.

So it is that the August 20th meeting of the New Hampshire Ruby group will take place at 7PM at The Rosa Restaurant on State Street, Portsmouth, NH. We’ll have a good meal and swap ideas about where to learn more about Ruby. The announcement. more details and directions can be found on the NHRuby.org web site. Hope to see you there!

Notes from MonadLUG, 9-July-2009, Charlie Farinella and OpenBSD

By on July 14, 2009 in LAMP, Linux, OpenSource, Technology

Seven people made it to the July meeting of the Monadnock Linux User Group, MonadLUG, held as usual on the second Thursday of the month at the SAU #1 offices in Peterborough. (Note that there will be no August meeting.) MonadLUG is one of the many chapters of the Greater New Hampshire Linux User Group; keep an eye on that web site (and the mailing lists linked off that page) for announcements and upcoming meetings.

Charlie talked about his job and the many uses they have for some legacy machines (older PowerPC Macs, Pentium-150 boxes) that could be useful as single-task machines running mail server, router, firewall or other similar tasks. CentOS or other modern distros are too complex and demand too many resources, especially for older machines or VMs within a machine. OpenBSD has low resource requirements, a strong reputation for security and ‘correctness,’ ease of use and configuration. He showed a couple of virtual machines (VMs) running inside of VirtualBox on his ArchLinux ThinkPad. Charlie walked us through a basic installation, using an .iso of OpenBSD that appears as a CD to a new VM. He talked about network configuration, package management, ports, pf configuration, runlevels, service configuration and more. There were slides; I’ll post a URL if Charlie’s willing to send them along. OpenBSD looks like an ideal, minimal OS for a dedicated-function machine.

Finishing a little early, Charlie talked about his company’s move to Zimbra and the kinds of collaboration they plan to do with it. Audience participation about other competing packages like eGroupware and LifeRay was quite interesting. A replacement for Exchange and/or Sharepoint is needed in a lot of companies, and this seems to be a popular FAQ.

Note there is no August meeting, as MonadLUG takes a summer break.

September 10th will have the MondaLUG host a presentation by Patrick Galbraith. Pat blew us away with his first presentation on MySQL. This is a not-to-be-missed meeting for anyone using MySQL.

Thanks to Charlie for the great presentation and to Ken and the SAU for the fine facilities.

CentraLUG, 6 July 2009: Philip Sbrogna, WINE

By on June 23, 2009 in Home Page, LAMP, Linux, Microsoft, OpenSource, Technology

WINE may or may not stand for “WINE Is Not an Emulator;” you might consider coming to the meeting to find out.

The July meeting of the Central New Hampshire Linux User Group, CentraLUG, will happen on the usual first Monday of the month, starting at 7 PM at the Hopkinton Public Library’s Community Room. Gather for Q&A and informal chat at 6:30.

Philip Sbrogna, an activist with the Monadnock Linux User Group, MonadLUG, will be presenting WINE. Philip got his start in the field of computers programming games for early microcomputers in ’79 after which he spent some time on mini’s at DEC. After an intermission on submarines he returned to the world of corporate computing where his daily fare at a small southern NH company provides him some opportunity to do the DB & Web dev thing. Personal interests include optimizing algorithms & innovative datastructures; particularly NXDs. He’s been a Linux enthusiast since switching from Coherent to Slackware in ’94.

Learn more about running Windows programs under Linux natively (Ubuntu Jaunty for presentation). Talk will include architectural overview & practical demonstration of what works and what doesn’t. Bring your favorite Window program along to see how it fares.

Note this meeting is at the Hopkinton Public Library 61 Houston Drive, Hopkinton/Contoocook, NH. Google map here. (Also, if you are coming from the southwest on route 202/9, the route 127 road over the Hopkinton Dam is once again open after a long repair closure.)

No CentraLUG meeting tonight

By on June 1, 2009 in Home Page

I had no luck in securing an alternate location in time to advertise the Central NH Linux User Group meeting that usually meets the first Monday of the month, and so have canceled the meeting. Please join us in July on July 6th at the Hopkinton Public Library when Philip Sbrogna will make a presentation on Wine, the Windows runtime environment for Linux.

Notes from PySIG, 28-May-2009

By on May 29, 2009 in Apple Macintosh OS X, LAMP, Linux, Microsoft, MySQL, OpenSource, PostgreSQL, Python, Technology, Web Development

It was a dark and stormy night. Nonetheless, six members made it to the May meeting of the Python Special Interest Group, held as usual on the fourth Thursday of the month at the Amoskeag Business Incubator in Manchester.

We had an Open Mike Night format, a round-table discussion where everyone shared what they were working on.

I plugged upcoming meetings, available as always at http://gnhlug.org — MonadLUG in particular, is to be praised for posting 4 months worth of meetings in advance.

Mark has a client who’s weaning off a proprietary OS and looking for a replacement document management system / word processing system, and is considering LyX, which is a  front end to LaTeX and has numerous utility scripts written in Python. Mark asked for suggestions for additional resources and the two Bills were able to come up with some ideas.

Arc talked about some wireless technologies he’s researching (neat stuff!). Arc also reported the Gaming SIG is coming along nicely: 5 people at the first meeting, 10 at the second. Details at gnhlug.org . Hoping to schedule a FPS (First Person Shooter) night soon. Coming up next Friday June 5th, the SIG will take a look at the awesome audio utility, Audacity, as it relates to gaming, and then engage in the Battle for Wesnoth.  Gaming SIG meets at the Brady Sullivan building in the DynInc offices on the fifth floor – see http://wiki.gnhlug.org/twiki2/bin/view/Www/GamingSIG.

Shawn O’Shea completed a course in Network Design and Planning at UMass Lowell (and got an ‘A’, congrats!) and showed us his lab work, written in Python! He very bravely showed us his code and we talked about some of his algorithms and looked at a couple of the modules he used, including optparse, netaddr and cmd.

Bill Freeman reported he’d been working in Plone and Python 2.4 and missed some of the features available in later versions. He created some code to address the worst of the deficiencies, and hopes to be able to release it freely soon. Stay tuned.

Thanks to Bill for organizing the meeting, to the Amoskeag Business Incubator for the fine facilities, to Arc for bailing us out with an extension cord, to Janet for the awesome (!) cookies, and to all for attending and participating!

CentraLUG Notes, 4-May-2009, Cole Tuininga on MySQL Optimization

By on May 28, 2009 in LAMP, Linux, MySQL, OpenSource, Technology, Web Development

Sixteen people attended the May meeting of the Central NH Linux User Group. Thanks to Larry Cook and Sybase for the use of their meeting room and projector!

Announcements:

  • David Marston, SwaNH Dinner, May 14th
  • Maddog: working with Koolu on Freerunner-based phone, running “Cupcake,” the version 1.5 of the Google Android phone OS. See http://www.engadgetmobile.com/tag/koolu/ and
  • Me: watch gnhlug.org for future meeting announcements

Cole works for Dyn Inc, the parent company to DynDNS and the other Dynamic companies. Cole Tuininga presented tips and tricks on optimizing the performance of MySQL in high-traffic, large-dataset situations. He talked about the selection process Dyn, Inc went through to select databases and the large scale processes they have automated at Dyn. You can find the slides on the GNHLUG site at http://wiki.gnhlug.org/twiki2/bin/view/Www/MySQLOptimization.

By the way, seven of us made it to Panera Bread before the meeting for a breaking of the bread. I hope to make this a regular extension to the regular meetings.

Thanks to Larry Cook and Sybase for providing the facilities, to Cole for the presentation, to all for participating!

June meeting *Might* be next week, or we may have to reschedule — securing a location has proven to be a problem. Stay tuned.

Notes from MonadLUG, 14-May-2009, Tim Wessels and Kablink

By on May 27, 2009 in LAMP, Linux, Microsoft, MySQL, OpenSource, Technology, Web Development

Five people attended the May meeting of the Monadnock Linux User Group. Thanks to Charlie for scrambling at the last minute to secure the Peterborough Town Library for the meeting, as our regular venue was unavailable. Charlie made the iniital announcements – Ed Lawson presents Scribus in June, Charlie will show OpenBSD in July, no August meeting, and Patrick Galbraith returns for another (not-to-be-missed) meeting on MySQL in September.

Tim Wessels did the main presentation of the evening. Kablink is the Open Source version of Novell’s Teaming product, bought from SiteScape, Inc., a company that started in Clock Tower Place in Maynard, MA. The Open Source version had been known as ICECore previously. Source code can be downloaded from http://www.kablink.org and sourceforge. Tim discussed some of the history of the project, where and how it is being used, possible ways to configure it for workgroup and corporate enterprise use. and reviewed some of the challenges and tricks to installation and configuration. If you’re looking for an Open Source competitor to Microsoft’s Sharepoint, with the ability to create portals, finely-control roles and access, and scale to thousands of documents, Kablink is worth investigating.

Thanks to Tim for the presentation, Charlie for running the meeting, and all for attending!

Tonight, MonadLUG (new location): Tim Wessels, Kablink

By on May 14, 2009 in Home Page

If it’s Thursday, it’s LUG-Day. Tonight: Tim Wessels demos Kablink open collaboration at MonadLUG: http://mail.gnhlug.org/pipermail/gnhlug-announce/2009-May/000709.html – 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!

Thanks to Tim Golden for arranging a WebEx recording of our meeting last Thursday. It’s nowhere near as good as being there, but it does leave more pizza for the rest of us!
