I’m Blogging This…

By Ted Roche on February 2, 2007 in Home Page, LAMP, Linux, Technology

Live from FUDCon Boston 2007 at Boston University’s Photonics Center. Wifi provided by the Fedora group, beautiful facilities. The Unconference format got presenters to do a 2-minute elevator pitch for their sessions. We took a break and voted on the sessions we wanted to attend, and the organizers shuffled the large and small rooms and time slots and I’m sitting in the first sesion on Mugshot.

Got to see a neat piece of hardware presented by an foaf as we got coffee. The Pepper Pad is a lightweight Linux-based, AMD Geode-based handheld Etch-A-Sketch sized device with full video capabilities, wireless networking, USB, and lots of features. It’s based off Fedora Core 4 with their own yum repositories. Nice form factor, major cuteness factor.

Livingston: Upgrade Vista with Vista

By Ted Roche on February 1, 2007 in Home Page, Microsoft, Technology

In Brian Livingston’s “Windows Secrets” newsletter, Brian writes, “Windows Vista, in my opinion, is a big improvement over Windows XP in many ways. But the new operating system is distinctly overpriced.” and “But I’ve tested a method that allows you to clean-install the Vista upgrade version on any hard drive, with no prior XP or W2K installation — or even a CD — required.” While this is good news for all who want to upgrade their hardware while installing Vista, it points out a way to buy the cheaper Upgrade version and get the same effect as the more expensive Full version.”

If you choose to dance with the devil, you need to pay the devil his due. A far better choice to send a message to Microsoft that their software is overpriced is by purchasing a Mac or installing Ubuntu or Fedora or Red Hat or SuSE or Debian or just sticking with the software you have. That’s how the market works. Using Microsoft’s software in violation of their questionable licenses just puts you in a bad position. I’m surprised to see Brian presenting it this way: it’s a handy tip for upgraders (and a best practice for getting a stable system), but it’s not the right path for people building new machines. I wonder if Microsoft will be able to patch this behavior to detect this kind of “upgrade” or whether they’ll change their installer to prevent it.

Free Linux Device Driver Development

By Ted Roche on January 30, 2007 in Home Page, LAMP, Linux, OpenSource, Technology

Greg Kroah posts an open letter to all device manufacturers, offering free development of Linux device drivers through the new Linux Foundation (formerly Open Source Development Labs) here:

“The driver will be written by some of the members of the Linux kernel developer community (over 1500 strong and growing). This driver will then be automatically included in all Linux distributions, including the “enterprise” ones. It will be automatically kept up to date and working through all Linux kernel API changes. This driver will work with all of the different CPU types supported by Linux, the largest number of CPU types supported by any operating system ever before in the history of computing.”

Awesome! Read the entire post here

Hauppauge shipping wrong card in PVR-150 boxes

By Ted Roche on January 29, 2007 in Home Page, LAMP, Linux, Technology

Passing on a warning from the GNHLUG mailing list: at least at NewEgg.com, folks are reporting that when they buy a PVR-150, a card for capturing video off cable, they’re ending up with a different card in the box, one that’s not compatible with current PVR-150 software. At our MerriLUG meeting 11 days ago, we had Jarod Wilson presenting on MythTV and the PVR-150 got prominent mention. It’s been on sale recently in on of the Big Boxes. Perhaps it’s being discontinued? In any case, the manufacturer needs to make good on what they claim is in their boxes. Hopefully, this is just a packaging issue.

Followup: nope, it appears to be intentional by Hauppauge. There’s an entry in their Wikipedia page referring to this, and a quick Google shows that this is a known issue on the mythtv.org site and the ivtv-users mailing list. Very disappointing behavior. Caveat emptor.

Watering the Net Roots | Linux Journal

By Ted Roche on January 24, 2007 in Home Page

Blogging over at Linux Journal in “Watering the Net Roots,” Doc Searls suggests “On the one hand, you can look at Verizons dumping of rural New England business as a kind of red-lining.” That’s the view of the IBEW over at stop-the-sale.org: 3,000 CWA and IBEW Members Fight Rural Telecom Redlining In New England

“Verizon’s landline sell-off is yet another example of a race-to-the-bottom economy,” said Verizon customer service rep and CWA Local 1400 Vice President Mike O’Day, at a public forum in Burlington sponsored by newly elected U.S. Senator Bernie Sanders. “It will adversely affect our jobs and the quality and reliability of local phone service throughout the whole region. Vermonters will be at the mercy of a small, highly-leveraged North Carolina-based company that will try to make a quick profit for its investors.”

In a recent NHPR interview, an economic development specialist stressed the importance of bringing more internet access to New Hampshire, especially the North Country, to develop local high-tech jobs to replace those lost as tourism and the snow season melts away.

Things we wish we’d known about NAS devices and Linux Raid

By Ted Roche on January 22, 2007 in Home Page, Linux, Technology

Thinking about deploying NAS? Before you do, you ought to read through Things we wish we’d known about NAS devices and Linux Raid by Daniel Feenberg of the National Bureau of Economic Reasearch, a private, nonprofit, nonpartisan research organization boasting 16 of the 31 US’ Nobel prizewinners in Economics as past or present staff members. Having reliable data to work with is important to them. There are some interesting lessons learned in the humorous reviews of systems they have used:

“That turns 20 minutes of scheduled downtime to several days. I can only assume the motivation was to discourage the upgrade.”

“Later, NFS exports of snapshots were added at our request. This is the only time any NAS vendor was willing to learn anything from us.”

and

“I’d be very reluctant to put data on a proprietary system with no aftermarket support. Every vendor is in constant danger of being acquired, divested or turned around. When that happens you and your box are no longer “strategic”, and contract or not, requests for help are likely to be brushed aside. Even with an enforcable contract, the vendor can easily discourage calls for service by proposing solutions that don’t save your data.”

and

“In a crowded server room you won’t be able to tell which system is beeping, so some visual indicator is essential – but not generally provided. ”

Excellent pointers, worthy of review. There’s also some good discussion of the statistics and odds of disk failures and double failures. Well worth a careful review if you need to be thinking about storing a large amount of data reliably.

Eric Sink: Baptists and Boundaries

By Ted Roche on January 20, 2007 in Home Page

Eric Sink, a fine essayist and software developer, does a little vanity Googling in “Baptists and Boundaries” and makes several excellent points about people and their world views, the punchiest of which is “Objects in browser are smaller than they appear.” Do read the essay and enjoy.

I’ve been involved in several insular communities (Commodore, GEOS, Amiga, FoxPro) that believed that they had The One True Truth and all others were mistaken, ignoring the growing evidence outside the walls that other alternatives might have something going for them, too. My biggest shock in my journeys outside the Microsoft Reality Distortion Field has been discovering that there are rich and powerful tools, long traditions of software excellence and some subtle (and blatent) differences in culture. The rich bazaar of choices: BSD vs. UNIX vs. Linux vs. Solaris, Perl vs. Python vs. PHP vs. Ruby, PostgreSQL vs. MySQL vs. SQLite vs. BerkeleyDB, tabs vs. spaces, vi vs. emacs, n-tier vs. mvc, African vs. English swallow, only add to the richness and freedom of the environment.

The biggest complaint of people stuck with a one-size-fits-all solution is that there is no choice. The biggest complaint when faced with the dazzling alternatives of FOSS is that there are too many choices. With great choices comes great responsibility. Conversely, “choosing” to stay with a one-size-fits-all monolithic solution is no choice at all, but rather an abdication of responsibility and a surrendering of freedom. Choose wisely.

CentraLUG, 5-Feb-2007: Matt Brodeur and GnuPG, OpenPGP, keysigning

By Ted Roche on January 18, 2007 in Home Page, LAMP, Linux, Security, Technology

The monthly meeting of CentraLUG, the Concord/Central NH GNHLUG chapter, happens the first Monday of most months on the New Hampshire Institute Campus starting at 7 PM. Next month’s meeting is on February 5th at 7 PM.

Directions and maps are available at http://www.centralug.org and on the NHTI site at http://www.nhti.edu/welcome/directions.htm. This month, we’ll be meeting at our usual location in the Library/Learning Center/Bookstore, room 146, marked as “I” on that map. The main meeting starts at 7 PM, and we finish by 9 PM. Open to the public. Free admission. Tell your friends.

At this month’s meeting, Matt Brodeur will present an introduction to e-mail and file security using Pretty Good Privacy (PGP). The talk will cover basic concepts of encryption and digital signatures. Examples and demos will use GNU Privacy Guard (GnuPG), a free (GPL) implementation of the OpenPGP standard available for most modern operating systems. Following the presentation, a PGP keysigning event will be held. Anyone interested in exchanging key signatures with other local PGP users can find details on our website,… as soon as we’ve set it up. Stay tuned.

Matt Brodeur is a Quality Assurance Engineer at Red Hat in Westford, MA and volunteer in local LUGs. He has previously presented OpenPGP talks at the Boston Linux & Unix User Group.

More details on the group and directions to the meeting can be found at http://www.centralug.org and at http://www.gnhlug.org.

The silent victory of Linux-as-geology at CES 2007 | Linux Journal

By Ted Roche on January 9, 2007 in Home Page, Linux, OpenSource, Technology

In his Linux Journal blog, Doc Searls observes “the silent victory of Linux-as-geology at CES 2007:” “But it becomes clearer with every show that the growing majority of Linux Stories are because effects. Meaning they are about what you can do because of Linux rather than with it.” Bingo!

Dabo rocks!

By Ted Roche on January 8, 2007 in Home Page, LAMP, MySQL, OpenSource, PostgreSQL, Python, Technology

I’ve mentioned it before, but the dabo project rocks! dabo is intended to be a cross-platform (Mac/Linux/Windows/Everywhere) rich-client application (like FoxPro 2.5 before MS bought it) with the rich-client experience (grids, list boxes, checkboxes, pageframes, menus, multiple forms) in the appropriate widget-set for each OS. It supports a slew of backend data sources (MySQL, PostgreSQL, MSSQL, Oracle, more) and is designed with a similar architecture (UI-BizObjects-Data) to many of the FoxPro frameworks. Best of all, it’s written in Python and available under an Open Source license.

I’ve spent a couple days downloading the source, watching the excellent screencast tutorials, browing the extensive mailing list archives and wiki, running the demos, generating an app with the App Wizard and reading the code. I’ve got an existing LAMP application that would benefit from a rich-client component with reporting capabilities, and dabo looks like a good choice. Hope to blog my progress as I get into it.
