Monday March 6th: CentraLUG meeting: Linux Terminal Server Project (LTSP)

By on March 3, 2006 in Linux, OpenSource, Technology

The monthly meeting of CentraLUG, the Concord/Central New Hampshire chapter of the Greater New Hampshire Linux Users Group, occurs on the first Monday of each month on the New Hampshire Institute Campus starting at 7 PM. This month, we’ll be meeting in Room 146 of the Library/Learning Center/Bookstore, http://www.nhti.net/nhtimap.pdf , marked as “I” on that map. Directions and maps are available on the NHTI site. Open to the public. Free admission. Tell your friends.

This month’s meeting will feature Steve Amsden, Network Administrator for the Merrimack Valley School District, showing off LTSP, the Linux Terminal Server Project. From Steve:

“LTSP is an add-on package for Linux that allows you to connect lots of low-powered thin client terminals to a Linux server. Applications typically run on the server, and accept input and display their output on the thin client display. The power and flexibility of this platform have far reaching implications, particularly for K12 school districts who have been educated and brave enough to seek other solutions than the cost of systems and applications software. But more specifically, being locked into a treadmill of constant upgrades, licensing problems, and unsupportable client-server nework environments that have been the Achille’s heel of technology education. Merrimack Valley School District has five LTSP server environments in various states of implementation, and
uses e-Smith Linux server for gateway, DHCP, content filtering, firewall, and Windows 2000 emulation using SAMBA. Exeter School District, as well as Salem, are too using combinations of e-Smith and LTSP. Though LTSP has made in-roads into the schools, it will be some time before the full impact is realized, and others convinced that there is a better way than the Microsoft Way.”

Should be an awesome presentation! Hope to see you there!

Dartmouth Lake Sunapee Linux User Group tomorrow: Jonathan Linowes on Xaraya

MacBook boots Linux, runs Knoppix!

By on February 22, 2006 in Apple Macintosh OS X, Linux, Technology

OSNews reports Knoppix on the Intel-Based Macintosh. “We reported a few days ago that we had Linux booting on the Intel-based Macintosh. We have been looking at Linux on this hardware some more, and we are glad to report that we now have a full-fledged Knoppix distribution working, complete with the X Window system. We are releasing the first pictures of Knoppix 4.0 running on a 17-inch iMac Core Duo. The X Window system is shown running at full resolution (rather, fuller resolution – 1472×900 – notice that the bottom right edge of the KDE dock is cut off). Most (but not all) aspects of the hardware seem to work, but we have yet to analyse exactly what doesn’t work and assess how much work it might take to get such things working.”

Awesome! Linux booting on the MacBook could lead to a dual-boot, dual-proc laptop.

Andy Bair demos WebJob at GNHLUG-nashua tonight

By on February 16, 2006 in Linux, OpenSource, Technology

Who : Andy Bair

What : WebJob

Where: Martha’s Exchange

Day : Thur 16 Feb (*TONIGHT*)

Time : 6:00 PM for grub, 7:30 PM for presentation

WebJob is a client-server system, where a tiny client requests and
downloads a program from a server, executes that program on the client,
then uploads the results to the server.

WebJob provides a mechanism for running known good programs on
damaged orpotentially compromised systems. It is ideal for remote
diagnostics, incident response, and evidence collection.

WebJob also provides a centralized management framework. It thereby
supports and automates a large number of common host-based tasks such
as: periodic system checks, file updates, integrity monitoring,
patch/package management, and so on.

Andy plans to discuss the tool, its architecture, and one or more
demos.

Andy adds:

WebJob is a client-server system, where a tiny
client requests and downloads a program from a
server, executes that program on the client,
then uploads the results to the server. WebJob
is useful because it provides a mechanism for
running known good programs on damaged or
potentially compromised systems. This makes it
ideal for remote diagnostics, incident response,
and evidence collection. WebJob also provides a
framework that is conducive to centralized
management. Therefore, it can support and help
automate a large number of common administrative
tasks and host-based monitoring scenarios such
as periodic system checks, file updates,
integrity monitoring, patch/package management,
and so on.

Here is the outline for the discussion:

  • High-level View
  • Details: Client–Server Interaction
  • Advantages
  • Disadvantages
  • Execution Example
  • WebJob in Action
  • Demos

Dabo does Reporting

By on February 13, 2006 in Apple Macintosh OS X, LAMP, Linux, OpenSource

–Paul McNett, Earthling posts Dabo Report Designer Screencast. “I’ve just put together a 23-minute overview of the Dabo Report Designer [Updated Link] in a screencast. It should give a good feel of Dabo’s current capabilities and design goals. Enjoy!”

Awesome! Dabo is looking more powerful, capable and slicker each time I check in on Paul and Ed Leafe. If you’re looking for a cross-platform rich client app this is worth checking out.

IT Conversations audiocasts I’m listening to this week.

By on February 7, 2006 in LAMP, Linux, OpenSource, Ruby, Security, Technology

While on the road to a client yesterday, I got to listen to a couple of audiocasts, as the mountainous terrain around here makes radio reception difficult. As I’ve blogged before, a five cent CD-R seems cheaper than the batteries to try to jury-rig an MP3 player to a FM transmitter to tune in on the car radio. Insert disc. Play. Very simple. On this trip, I listened to:

Joichi Ito: The Future of Blogging. “The Internet is truly becoming an open network with the rise of amateur content and open source software. In this talk, Joi Ito takes us through the growth of the internet as an open network in layers to the point where the killer app is now user generated content. Earlier, it was the little guys around the edges of the internet who created the open standards which made the web work, and today it is those same people who fuel it with their creativity. Joi also shares with us his observations of the remix culture seen on the net. [Accelerating Change audio from IT Conversations]” — quite the blast of conversation. The key point: user content, rather than mainstream media, is the next big internet wave. Great moment: Joichi points out that “amateur” comes from Latin roots of “from the heart” and doesn’t say anything about the quality.

Saul Klein, VP Marketing, Skype: “Skype has become one of the prominent disruptive technologies of the early 21st century. Allowing anyone with a broadband connection to make cheap calls all over the world and free voice, text (and now, video) calls to anyone on the Skype network, it has changed the way many people think of the telephone. Skype has influenced pricing and availability, and is so ubiquitous that it is lending its name to become the verb for using PC-based voice over IP… In this interview, Larry Magid talks with Saul Klein, VP Marketing of Skype. They discuss the changing nature of the telecom business, Skype’s new video feature and the potential for Skype to bring telephony to previously under-served markets.”

David Heinemeier Hansson, Developer, Ruby on Rails: Secrets Behind Ruby on Rails, “Ruby on Rails has received a lot of buzz among the web developer community, but many wonder exactly what the fuss is all about. In this high order bit from the 2005 O’Reilly Open Source Convention, developer David Heinemeier Hansson explains the secrets behind the success of Ruby on Rails.”

All audiocasts came from the IT Conversations: All Programs feed. Worth checking out, and considering supporting IT Conversations if they bring as much value to you as they do to me.

Give Upgrades A Chance

By on January 31, 2006 in LAMP, Linux, OpenSource, Technology

Over at Resigned to the Bittersweet Truth, Bill McGonigle posts Call To Action – Upgrading. “I spoke to Tim Burke, Director Emerging Technologies (including the Linux kernel and Fedora) at RedHat about the state of upgrading this past Tuesday at the GNHLUG meeting in Manchester…”

“So, I issue a challenge to all package maintainers out there who have their projects integrated into distributions like Fedora – give upgrades a chance.”

It’s a tough challenge, but a necessary one. Upgrading is inevitable, and the costs of updating/upgrading are becoming an increasingly important factor in calculating the total costs of owning a system.
