CentraLUG meeting, March 7th: Webrick, LinuxWorld wrap-up

David Berube, our fearless leader, posts: Monday, March 7th – Webrick and Linux World. CentraLUG is having another great meeting on Monday March 7th, and this time, we’ll be covering Webrick, a powerful system for easily creating custom webservers in Ruby. With Webrick, it’s easy to drop a full webserver into any application. We’ll also have a brief recap of LinuxWorld. Per usual, there will be copius amounts of free caffeine.

It’s at the NHTI. You can get directions on the NHTI site: http://www.nhti.net/frames_Map.html. It’s in the Library/Learning Center/Bookstore, marked as “I” on that map. The room is 146, and it starts at 7:00.

IBM ‘hypervisor’ software makes stealth debut

“Big Blue enters market for software that lets a computer run multiple operating systems simultaneously, CNET News.com has learned.” [CNET News.com] And it looks like IBM is very interested in sharing the technology, releasing it as open source and collaborating with the separate Xen project.

Virtualization was big news at LinuxWorld last week, as this article also on CNET news.

LAMP course starts Tuesday at NHTI

I’m pleased to announce that I will again be one of the teachers at the LAMP course at the New Hampshire Technical Institute‘s Center for Training and Business Development. We start teaching on Tuesday night, and will be teaching ten evenings Tuesday and Thursday, 6 PM to 9:30 at the Concord campus. There’s till time to sign up and catch the first class — details are available at the CTBD site. We taught this class in the fall semester and it was a great success. At the end of the course, the students have a simple interactive database-backed web site running on Linux, Apache, MySQL and PHP.

Delivering a commercial LAMP app

Friday was spent at the client’s delivering the final beta of the first phase of a five-phase LAMP (Linux-Apache-MySQL=PHP) project. Client was ecstatic! But, of course, I came home with a list of small adjustments to punch through. Hope to tell more as it unfolds. Briefly, it’s a simple data entry and reporting system: 20 tables, 40 web pages, used by an inhouse staff to manage their workflow. This first piece got rid of the worst of their manual labors. Later phases will produce documents to present in a customer-facing web site, and tighten up the workflow tracking. Phase I was 40 hours of analysis and design with customer interviews, document review and resulted in a design document of workflow, prototyped web forms and an ERD (data model). The model was dead-on, requiring just a couple adjustments. Eighty hours of coding produced the forms and got us through the beta testing and demonstrations. Client goes live with a pilot test next week.

LinuxWorld

Sorry for the light blogging. Spent Thursday at LinuxWorld in Boston; got to see lots of vendors big (IBM, Intel, AMD, Novell, Red Hat) and small (X.org, LTSP.org, GNHLUG.org) and hang out with some cool folks. [Update: fixed malformed link above.]

MySQL Launches MySQL Network

Latest Updates from MySQL AB, the PR department for MySQL AB via RSS announces: MySQL Launches ‘MySQL Network’ for Corporate Enterprises Looking to Fast-Track Open Source Database Deployment. Boston, LinuxWorld Conference & Expo — “MySQL AB, developer of the world’s most popular open source database, today launched a new way for corporate enterprises to acquire, deploy and support MySQL for their business-critical applications.
The new ‘MySQL Network’ offering is specifically designed for large IT departments looking to leverage the cost and performance benefits of MySQL — while addressing key business requirements for implementing open source software.”

Anyone up for a game of Buzzterm Bingo? Sheesh.

O’Reilly’s MAKE magazine, Dan Bricklin, and Linux innovation

Dan Bricklin’s Log says Get Make Magazine. “I started to read MAKE I got goose bumps. There’s real hope for the next generation.”

I have fond memories of building stuff with my Dad – crystal radio sets, adding a vernier dial to a shortwave set, building a couple of electronic sets, learning how gears and cams and pieces make ratchets and convert rotary power to linear and so forth. MAKE magazine seems to continue the tradition of taking things apart and (we hope) putting them back together, perhaps a little differently, perhaps a little better.

At my recent presentation to the Dartmouth-Lake Sunapee Linux User Group, I showed off the LinkSys WRT54G. As soon as we were done, I offered to pop the cover off my router so we could look inside. I was immediately surrounded. My fellow LUGgers could immediately identify the serial port solder pads on the circuit board, identify the RAM, EEPROM, radio transceiver, and so forth. I asked who was confortable using a soldering iron and better than half the hands went up. As the evening wore on, there was discussion of leasing a T-1 and turning yourself into the local community wireless ISP – several members had done that – and the 3 dB attentuation per meter of leaves when trying to reach more distant sites, how to get broadband to remote rural locations, and experiences with different DSL providers.

Innovation lives.

Peterborough MonadLUG meeting cancelled

The National Weather Service maintains a great set of RSS feeds so that you can get any alerts, warnings or advisories in your RSS aggregator. I’ve been watching the incoming snow storm for two days. Just in case you were thinking of visiting the Monadnock group because of the posting I put up here earlier this week:

“Due to the winter storm about to hit our area and some forecasts showing a worst case of up to 20 inches of snow by tomorrow, this month’s Monadnock Linux User Group meeting will be cancelled.”

“We will resume the normal meeting schedule next month, second Thursday of the month. More announcements will follow as we get closer to that date. ”

MonadLUG Coordinator

MonadLUG’s meeting announcement mailing list is having a few problems at the moment, but consider signing up in a few weeks to stay abreast of their activities.

Microsoft kills another word: interoperable joins innovation

Computerworld News reports “Microsoft’s Gates vows ‘interoperable’ software. In a lengthy letter to customers yesterday, Microsoft Chairman Bill Gates spelled out a new mission for his company’s software: better interoperability. ”

That’s just silly. Microsoft got into the market interoperating with IBM LAN Manager, then Novell networking. Until Microsoft actually shows they are acting differently, this is just a rehash of “Embrace, Enhance, Extend, Extinguish.” Microsoft is using their marketing machine to kill the meaning of another word, just as they distorted the “right to innovate” to mean “using monopolistic practices to dominate a marketplace and crush competition,” they are trying to redefine “interoperate” to mean “Microsoft can access everything but no one can access them.”

Recently, Microsoft was embroiled in a controversy over theopennessof their Office XML. (HINT: Don’t bother, go with OpenOffice.org’s soon-to-be-OASIS-standard format. Tools are out there.) The resolution was for Microsoft to issue a new license for their XML that effectively limits others to read and not write the format, and also a poison-pill requirement that software contain a clause specifying the technologies are licensed from Microsoft, a requirement which prevents the formats from being used in GPL software.

It is interesting to note that Microsoft is trying this tactic. Let’s see what happens next.
