Community Assistance with Presentation

Next week I will be part of a panel on virtualization at an HP event in NY for financial CIOs.  The panel is focused on these topics about open source software and virtualization, listed below. If you have any thoughts that you would like expressed by me at this event let me know. This is a great chance for our community to express our thoughts on virtualization and open source in the enterprise.

  • Open Source vs Proprietary Virtualization
  • Challenges / issues customers face with virtualization in the enterprise
  • Open source applications vs proprietary applications for virtualization
  • What – Where – How to Virtualize
  • Cloud Computing – What are Risks?
  • Virtual Appliances

Open Source Business Conference 2008 Update

I am back from the OSBC 2008 event in San Francisco and wanted to share my notes from the sessions I attended as well as some thoughts on the overall event. Feel free to add any comments on the material and I will answer your questions.

Notes from Day 1 and Day 2: infoworld-open-source-business-conference.pdf

Overall thoughts:

  • Dress – Wow, when did an open source event look like a meeting for lawyers and bankers with everyone in suits? This was the most “dressed-up” event I have been to since an event in Germany I was at a few years back. I guess open source must be real if everyone wears suits?
  • Is Open Source Business Model any different than Proprietary Software Business Model? More thoughts on this in another blog entry but I am beginning to think that there is less difference b/w the models than most people think
  • Microsoft – Brad Smith the SVP and General Counsel at MSFT came to talk about licensing issues b/w MSFT and the Open Source Community (See Notes) and I was impressed that he was willing to spend 90 minutes and take open questions on a variety of topics. It seems to me that MSFT has decided to only have discussions with “Cathedrals” and not “Bazaars” and that this decision is creating the fundamental problem with trying to solve a variety of legal and licensing issues.
  • Open Source Projects – the new companies in Open Source are doing an amazing job of building solutions by taking a variety of open source projects and bundling them into a solution for the enterprise; I do wonder if the emphasis on building solutions for CRM, databases, and other common technology areas is limiting. Open Source should be looking for new areas to innovate such as social networking products for the enterprise (see notes) rather than established computing areas.

Comments on Matt Asay’s blog posting (http://www.cnet.com/8301-13505_1-9904446-16.html) about the event. He was the event chair.

Amusing blog link (go back in time via arrows to read history) – did like the comment on the expensive breakfast but the direct link is on the MSFT pitch (http://blog.generationjava.com/roller/bayard/entry/ms-keynotepanel)

Great blog link to people who wonder why Microsoft sponsors open source events and if it has an impact: http://boycottnovell.com/2008/02/25/ms-open-source-business-conference/.

The Xen of Static Checking, Part 1: bug-free code without the effort

OK, maybe the title of this post is a slight exaggeration but it’s good to have goals for the future!

It’s a goal which many would argue will be unreachable without the genesis of Strong AI. It’s also a goal where we can achieve very useful results just by trying to get there. I’m going to write a series of articles about my current work on static checking the Xen codebase. The goal here is to find errors before they occur, spot bugs that aren’t caught by human reviewers and improve the overall quality of codebase. Unfortunately, global harmony and toast which doesn’t fall butter-side-down are probably still outside the scope of this work – sorry.

This first article gives an overview of the historical background of static code checking. Future articles in this series will describe what I’m doing to apply static checking to the Xen codebase and the possibilities for Xen in the future.

History of Xen – Architecture

As I continue to learn more about Xen, I find it interesting to read old documents that show the transformation of Xen from a research project at Cambridge University to the current leading open source hypervisor technology. A great link form Cambridge University is available with a collection of documents and presentations. I would like to highlight two documents that I found worth reading:
