Open Source means that users have the freedom to see how software works, adapt it for the own needs, fix bugs and limitations and contribute back to the community.

Notes from PySIG, 24-July-2008: Improv Intro

Seven attendees made it to the July 2008 meeting of the Python Special Interest Group of the Greater New Hampshire Linux Group, despite the heavy rains. Due to some last-minute conflicts, our planned speaker, Ray Côté, had to take a rain check for a future meeting, but cookies were made and we resolutely carried on.

There were two first-time attendees, one with a novice level of knowledge of Python and the second very little. Lead by the PySIG leader, Bill Sconce, we launched into an improvised session introducing Python and talking about its power, range and flexibility, comparing it with other languages, heckling Ben Scott, demonstrating several IDEs, talking about procedural scripting and object-oriented programming, showing off some working code, migrating database applications from proprietary platforms, and much, much more. A good time was had by all.

Prominently mentioned were the great tutorials available directly off the Python web site and the Tutor mailing list.

Great thanks to Janet for a delightful variety of cookies, to Bill for not only running the meeting and providing the projector but also bringing the milk, to all for participating, and to the Amoskeag Business Incubator for providing the fine facilities.

(Note: despite the organizational support of the GNHLUG, members running all sorts of OSes are welcome. A typical meeting has people running Python on OS X, Linux and Windows. All should expect equal-opportunity heckling.)

OpenDisc 08.07 released!

Chris Gray posts: “We’re pleased to release 08.07, the latest version of OpenDisc, with no less than twenty five updates, including Firefox 3 and the latest milestone versions of OpenOffice.org, FileZilla, Seamonkey and many more.” Grab the .iso or join the torrent at http://www.theopendisc.com.

The Open Disc has been a huge benefit in getting clients to see the power of Open Source. On a single disc they can install on all of their Windows machines, share with their friends, make a copy to take home, and it includes a complete office package (OpenOffice.org 2.4), a PDF driver (PDFCreator), diagramming tools (dia, InksScape), desktop publishing software (Scribus) and lots more. It’s a bargain at twice the price!

Catching up…

It’s been busy, busy month, and blogging was one of many things put off. Now, it’s time to start catching up.

I had an awesome month of June. Working on my main client project, we released yet another update on 12 June. After that, I took two weeks “off” — at least away from billing — to do some professional upkeep.

I spent a few days studying and then took the two MySQL 5.0 Developer certification exams on Tuesday the 17th. I went to the Blended Solutions facility in the Mall of New Hampshire, adjoining the PSNH building on Elm Street in Manchester, NH, and took the two exams, back-to-back. The first exam was the simpler of the two. Reviewing all the questions a couple times, I was still done in under an hour. The second exam, though, was a bear! The material was the more advanced stuff, some of the questions were trickier, some of the topics were material I had only book knowledge on. I marked a bunch of questions for review, went back and filled in all the answers, reviewed and debated and over-thought a bunch of questions and then, with three minutes left, decided any answers I changed in a panic were more likely wrong than right, and stopped. I passed both exams with acceptable scores, but nothing I’d brag about. “What do they call the man who graduates at the bottom of his class in med school?” “Doctor.” So, I’m pleased to have the opportunity to establish my level of knowledge, flag a couple of areas I need to learn more about, earn a logo I can display as part of my marketing and gain a listing as a MySQL Enterprise Ready Partner.

Wednesday the 18th of June was the first day of the Red Hat Summit in Boston. I attended all three days, commuting from Contoocook to the Anderson Rail Center in Wilmington and taking public transportation from there. While it made for a lot of hours on the road, the savings over staying in town were significant (total parking and rail for the week: $84 for 6 days), and sleeping at home in my own bed very much appreciated. The Red Hat Summit was a fascinating event. I wasn’t that familiar with the corporate structure or the market focus of Red Hat and I got much better insights into who they are and what they do. Here’s a slew of links on what went on, Red Hat announcements, and links to presentations.

Parallel to the Red Hat Summit was the Fedora Users and Developers Conference, FUDCon10 for short, that shared the Hynes Auditorium facilities on Thursday and Friday, and met at the Photonics Center at Boston University on Saturday. Even though many Fedora participants are Red Hat employees, the tone and structures of the groups are dissimilar. I missed a lot of the last-minute organizational notes the FUDCon’ners put together to organize their HackFest, so I tended to attend the Red Hat sessions instead. In the future, I’m more likely to put more effort into the HackFest side of things. Saturday was a BarCamp, a one-day self-organized conference. As I noted at last year’s conference, the means of pitching sessions, voting, scheduling and running the show are put together on the fly, and the results are startlingly good. Having pretty much had my brain filled of tech at the Red Hat Summit, I chose instead to focus more on process sessions, and learned about bug triaging, web site usability issues, and Fedora structure. A great use of a day, and a great chance to attach faces to the name and shake a few hands.

Sunday was a day of rest for me, and a day of washing laundry for Laura. Thank you!

Monday found me back on the Commuter Rail, this time attending An Event Apart just across the street from the Prudential Center where the Summit had been. Two long days of sessions were focused on the web, primarily design and usability, very different aspects from the two previous conferences. Like the Red Hat Summit, this conference was a little outside my comfort zone, in this case, designers rather than developers. Jeffrey Zeldman puts on an incredible show; facilities were superb, speakers knowledgeable, swag cool. Eric Meyer is the authority in the field of CSS, and it was his sessions I got the most practical tools from, but all of the sessions were well-presented, informative and thought-provoking. Jared Spool of User Interface Engineering had a very funny and very insightful session on analyzing clickstreams for success that will have me restructuring some of my client’s web sites. All of the speakers had great observations on the state of the art and future directions. Great stuff! Several other people took great notes I can share with you.

Arriving back to work on Wednesday, there was no time to decompress; a day of meetings lead to a couple frantic days of shipping yet another release and picking up another couple of projects. Thirty billable hours later, my super-contractor did a high-five tag-team tag and was off on his own adventures, while I took over sheparding a release out the door on Friday with some new features, new team members, new procedures and new prototcols. Whew!

It’s been an exhausting three weeks, but an exhilarating time, too. Hope to blog more details as I catch up on all the other projects.

Notes from CentraLUG, 2-June-2008: Mark Boyajian, Open Source Advocacy

Twelve folks attended the June meeting of the Central New Hampshire Linux User Group, held as usual on the first Monday of the month, but at the summer venue of the Hopkinton Public Library. Attendance was a delightful mix of regulars and new visitors.

As the crowd had some new members, I spent some time introducing the GNHLUG and its many chapters, its purpose and that upcoming events (there are many!) can be found on the gnhlug.org web site. We had a round of announcements and introductions and got into the main presentation.

Mark Boyajian has been working with Bill Sconce to demonstrate and encourage the use of Open Source software at the Lawrence Library in Pepperell, MA, strongly encouraged by the Library Director Debra Spratt. Deb has been instrumental in getting equipment set up, encouraging them to establish an information kiosk where they could feature news and posters about Open Source, as well as setting up an older machine with Linux. Mark brought along some pictures to show their setup and talked about the good reception they’ve got from attendees and the interest generated. Mark had some success stories to share and some interesting stories of the misconceptions he tried to address.

Thanks to Mark for the presentation, to Bill Sconce for providing the projector, to the Hopkinton Public Library for use of the facilities, and to all for their attendance and participation.

Notes from PySIG, 22-May-2008: IPython and Frangoes

Twelve folks attended the May meeting of the Python Special Interest Group, held as usual at 7 PM on the fourth Thursday at the Amoskeag Business Incubator in Manchester, New Hampshire. Vigorous discussion, idea exchange, job openings and, yes, Python, was discussed in depth.

Bill Sconce was the master of ceremonies and lead off with his usual printed agenda of items: Welcome, Announcements, a round of introductions, Janet’s Famous Cookies (this week, Frangoes! Awesome!), open announcements and discussions of gotchas.

Sample Q: how to debug binary text that may or may not be Unicode? A: Mark Pilgrim’s Universal Encoding Detector, [link updated, tr] originally part of his famous Universal Feed Parser.

Sample Gotcha: scripts with a she-bang line might not always be transportable between Windows, Unix and OS X because of line ending differences. If your parser complains about invalid commands on the she-bang line, make sure your line endings are correct for the platform.

Shawn K. O’Shea arrived and proceded to note every passing mention (with links!) in his great blog entry at: http://www.eth0.net/blog/?p=12 — thanks, Shawn!

Kent asked about using Python to interface with an existing C++ code and a lot of useful suggestions were forthcoming.

Arc updated us on the state of PySoy: the major bug that was crashing PySoy seems to have been isolated, and the code is orders of magnitude more stable. Bug fixing is proceding apace and an end-of-summer major release appears feasible.

Discussion on the upcoming Software Freedom Day got an enthusiastic reception, with several folks considering something in their communities.

On to the main presentation: Kent presented his monthly Kent’s Korner featuring the IPython interactive shell. IPython is slick, with a slew of features and quite a bit of documentation as well. IPython is not just a shell, but also an embeddable library that can bring scripting features into your application, and can also be used as a non-blocking interface to graphical environments like GTK, Qt and Wx (unlike the standard Python shell, which only works against Tk). Anyone doing a lot of work with Python from the shell needs to check out IPython!

Thanks to Kent for the presentation, to Bill for running and promoting the show, to Janet for the awesome Frango cookies, to Shawn for the excellent capture of the night’s events, to ABI for their great facilities and to all for participating!

openSUSE News » Thesis on openSUSE Published

A year’s research on Novell and the openSUSE project is now published as a master’s thesis at the University of Oslo. “Managing Firm-Sponsored Open Source Communities” details the collaboration between Novell and the openSUSE community. Community members and employees in Novell have participated in the study.

It’s cool seeing some serious study of how for-profit companies can work successfully with for-merit software development efforts like OpenSuse, Ubuntu or Fedora and make it a win-win situation for both. There’s a mercifully short executive summary for those who want the highlights, and the full 130+ page thesis available online.

CentraLUG, 2-June-2008, Hopkinton, NH: Open Source Advocacy

The monthly meeting of CentraLUG, the Concord/Central NH GNHLUG chapter, happens the first Monday of most months. On June 2nd, we’ll be meeting at the Hopkinton Public Library from 7 PM to 9 PM. (Directions and maps here. [Edit: updated to current link 2014, too late for you to make the meeting, sorry.]) Open to the public. Free admission. Tell your friends. At this meeting, Mark Boyajian, Bill Sconce and other special guests will discuss “Open Source Advocacy.” I hope this spurs some discussions on how we can duplicate their success and avoid problems they can experienced.

About the presentation: Mark and Bill have been working with the Pepperell (MA) Lawrence Library to raise awareness of Open Source software solutions. They kicked-off this effort with a presentation last October in support of Software Freedom Day. The enthusiasm of library director Debra Spratt resulted in the Lawrence Library Tech Talk series: a monthly presentation on Open Source software and issues. Additionally, Debra has facilitated the creation of an Open Source information kiosk as well as a Linux-based computer in the reference library for use by the public!

The Tech Talk series formally launched in February and has consistently drawn a good audience. The kiosk and computer have been up and accessible since March. The experiences of working with this rich environment has surprised, challenged, and taught us many things we never expected. We are all working and adapting to better understand the [technical] needs and interests of the community and how the library can support them.

About Mark and Bill: Mark is an IT consultant (Simple Solutions) specializing in curriculum development and training, database development, and information management using Open Source solutions wherever possible. Mark “started life” as a music teacher, spent 20 years as an environmental field scientist specializing in wetlands and data management, and launched Simple Solutions as a full-time endeavor in 2001 built on Open Source solutions.

Bill Sconce is the proprietor of In-Spec, Inc., a Milford, NH-based consulting company. Bill is an activist with the Greater New Hampshire Linux Group, Secretary to the Board of Directors and coordinator of the Python Special Interest Group. He’s presented to most of the chapters and advocates for Open Source software at many other venues, including the McAuliffe and the NELS/FOSSEd conferences.

Future Meetings: Stay tuned for details on the upcoming bbq/picnic all-hands meeting in July, and for the location of the August meeting, still TBD. As always, meetings are subject to change. You are encouraged to join the low-traffic announcement list at http://mail.gnhlug.org/mailman/listinfo/gnhlug-announce to get announcement and cancellation information.

Meeting promotions: I’ve posted this meeting at lots of locations: FindEventsFast, Eventful, zVents, Upcoming, the GNHLUG announcement list, NHPR, the Concord Monitor. I’d be interested in hearing about where you learned of the event to better tune the meeting promotions.

Notes from CentraLUG, 5-May-2008, Ben Scott, The Linux Server That Could

Nineteen people made May 5th’s CentraLUG meeting the second best attended of any LUG meeting so far this year, and the most populous CentraLUG meeting in over two years!

The meeting starting with a rag-tag band of Linux enthusiasts wandering around the campus looking for a room to meet. It’s finals week at NHTI and we’d been bumped from our regular spot. From the Library to the Crocker building to the Little Building we moved as more and more and more attendees arrived and we outgrew our first and second choices of rooms. Thanks to all for patience and multiple moves, and apologies for any folks we lost along the way.

The hassle was worthwhile, as Ben put on a great presentation on “The Linux Server That Could: Setting up a Small Office Server.” Over the years, both as part of his work and his hobbies, Ben has set up many multi-purpose computer servers: a single machine to serve a small workgroup with mail, files, printing, centralized DNS, DHCP. Ben had some slides to introduce the concepts and frame the problems his scripts solves, and then he dove into how to set up and configure the services. Providing a running commentary while he showed us configuration files, he offered a number of Best Practices tips for configuring, naming your intranet ‘domain,’ how CentOS/Red Hat family distros work, the differences in different flavors of Linux distros, editing configuration files, viewing error logs and more. It was a content-filled hour!

Slides and sample scripts and configuration files can be found on the GNHLUG web site here. Thanks to Ben for a great presentation, to Bruce Dawson for last-minute projector duty, to Bill Sconce for helping with the raffle, to the NHTI staff for helping us find facilities, and to all who attended and participated!

Koolu hacking

Found a couple of good leads on setting up the Koolu as a MythTV front-end, through persistent searching in specific forums, like the Ubuntu support forums and the MythTV mailing lists. A couple quick clues:

1. Hit DEL on startup to get into the BIOS, use the BIOS options to expand the memory dedicated to the video card. Options are: 32M, 64 M, 128 M. Not sure how much of an effect it will have.

2. Hit Shift-F10 early in the startup (prompt only appears for a second) to disable the RealTek attempt to launch the machine from a network boot image via PXE. This saves 10 or 20 seconds on every boot.

3. The /etc/fstab had an entry for a swap partition, but the UUID was incorrect. Just reassigning the device to hda5 rather than the UUID was enough to get the swap to come up.

4. I’m convinced there’s a way to get a lot more performance from the video, but need to dig in more. The AMD LX800 driver should support buffering, just need to find the trick to turn it on.

5. There’s an error in the Xorg.0.log file that indicates the kernel doesn’t support MTRR and should be recompiled to do that.
