I will be attending the 5th Annual Emerging Technologies for the Enterprise Conference (ETE 2010) this Thursday and Friday, April 8-9, 2010. The event is billed for “developers, architects, and IT executives” and attempts to provide a dynamic forum for “emerging technology and Open Source”. I look forward to seeing Robert C. (Uncle Bob) Martin’s keynote on “Bad Code, Craftsmanship, Engineering, and Certification”, a panel discussion on “Open source is a commercial enterprise”, another panel on “Social Media: Why should I care?”, a second Bob Martin presentation on “Agility and Architecture”, Mary Poppendieck on “Cost Center Disease”, Bonnie Aumann on managing developers, Michael Coté’s keynote on “The Pragmatic Cloud”, Geir Magnusson Jr. on “Project Voldemort”, and Brian McCallister on “Failure Happens” (one of the very few talks on systems administration). Then ... (more)

FOSS Linux Virtualization Tools

In January I attended the 10th annual Southern California Linux Expo. In addition to speaking and running the Ubuntu booth, I had an opportunity to talk to other sysadmins about everything from selection of distribution to the latest in configuration management tools and virtualization technology. I ended up in a conversation with a fellow sysadmin who was using a proprietary virtualization technology on Red Hat Enterprise Linux. Not only did he have surprising misconceptions about the FOSS (Free and Open Source Software) virtualization tools available, he assumed that some of the... (more)

Crossroads in FOSS Projects: Some Business Considerations

Open Source Journal At our Seminar last month, Managing FOSS to Lower Costs and Achieve Business Results, several participants asked about the dynamics of FOSS (Free and Open Source Software) projects that reach a crossroads (a failure, a merger, loss of key personnel, etc). I had not expected that concern because with commercial software, it seems to me, the problem is more severe. When you have the source code and the right to modify and redistribute it, the source gives many more options (and its freedoms provide many more protections) than when commercial software goes bankr...

Slides for my talk on “Automating X11 Keystrokes”

X11 is the graphical user interface most widely used on Linux operating systems. My slides and video demo for a short talk given at the Philadelphia area Linux Users Group (PLUG) on March 2nd are on-line. The slides briefly cover xrandr (which can also be used to set the screen resolution), xset, xwd / xwud, xdotool, and xautomation including xte. You can get the slides and watch the video at my page on Automating X11 Keystrokes. ... (more)

Learn Open Source Database Tools from Stanford for Free

I recently finished Stanford’s excellent free on-line course Introduction to Databases with Jennifer Widom. The course is a broad survey of database technology including XML, Relational Database Management Systems (RDBMS) from many angles (SQL forms the centerpiece of the course), OLAP (OnLine Analytical Processing) and NoSQL. I was very impressed with the breadth of Widom’s approach to the subject: it was a major reason I decided to spend time on the course. Another strength is its nuts-n-bolts approach: some theoretical topics are covered but for the most part this is a course... (more)
