There are dozens of virtualization products on the market. When we launched our first high-availability cluster in early 2008 we chose Xen due to it’s ability to run on non-virtualized hardware, support in Debian 4.0 (Etch) and general flexibility. We’ve learned a lot about...
Here is an effective way to try out Linux or FOSS (Free and Open Source Software) to help grow your organization. Hat tip to CIO magazine for Adam Hartung’s short little InnovationZone article “Outsource for Growth”. Mr. Hartung recommends outsourcing to grow your ...
Recently, I was looking for resources to help explain the implications of integrating FOSS (Free and Open Source Software) with proprietary software. This question is important for any organization who might want to build an “embedded” or “dedicated” system or ...
I attended DebConf10 in early August. I thought I’d document some of the initiatives that resulted from that event. I attended the Debian Policy BoF. It inspired me to start reviewing Debian Policy and led to my submission of a bug report to improve the description of the archi...
Since I’ve been involved with Debian GNU/Linux for over 15 years, it is exciting that I will be able to attend the first two and a half days of DebConf10 including Debian Day from Sunday to Tuesday August 1–3. I am particularly looking forward to the following sessions: Pe...
Last week I read a good article on cloud computing, Cloud ROI: A Grounded View. It seems that even with all the hype (or because of it?) most are not “running blindly” to adopt “the cloud”. I must admit the cloud metaphor has a powerful poetic charm to it. That is probably why it ha...
We have all heard this: You need to document the computer infrastructure. You never know when you might be “hit by a bus”. We hear this and think many frightening things, reassure ourselves that it will never happen and then put the request on the back burner. In this article I will ex...
A couple weeks ago I wrote that I would be attending the 4th Annual Linux Foundation Collaboration Summit. I wrote about much of my experience there and at the Open Source Business Conference back in March over in my personal blog: “Lessons from Open Source Business Conference an...

Blocking e-mail spam at the time of SMTP (Simple Mail Transfer Protocol) transfer has become a best practice. There is no point wasting precious bandwidth & disk space and spending time browsing a huge spambox when most of the incoming flow is clearly spam. At LinuxForce our e-m...
In February 2009 Debian released version 5.0, “Lenny” with more than 25 000 packages including many security enhancements such as PHP’s Suhosin system. LinuxForce has compiled a list of 49 news articles documenting milestones of the Debian GNU/Linux project in 2009: ...
Although I haven’t seen a thoroughly researched study, I figure there must be at least 250,000 FOSS (Free and Open Source Software) tools available to every systems administrator on the planet (230,000 at SourceForge + 15,000 at Launchpad + 12,000 at CodePlex + 5,000 at Google Code and...

Although my presentation focused on individual contributions, these lessons also apply to how businesses benefit by contributing to FOSS. When a business approaches a project they should attempt to build a symbiotic relationship with the community. Such a relationship involves followin...
This blog is part of a new educational initiative to foster a deeper understanding of the capabilities and issues involved with administering FOSS (Free and Open Source Software) to deliver concrete business benefits. Although our subject will sometimes become technical, we will strive...
Virtualization provides the facility to run multiple isolated computer operating systems on one piece of computing hardware. There has been a huge increase of interest in virtualization technology because recent advances in multi-core technology provide significantly more computing pow...
Mary Hayes Weier wrote an interesting article in this week’s edition of InformationWeek on "Alternative IT: CIOs are more receptive than ever to new software models". What is great about her article is how she captured the divergent views on IT models (such as SaaS, clou...
If you know the history of LinuxForce, you know that we’ve been doing remote systems administration using FOSS (Free and Open Source Software) since our founding in 1995. And we’ve called our remote systems administration service Remote Responder℠ for a long time to...
