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 bankrupt or gets bought by a competitor for instance. But the reason for the questions may be a lack of understanding about how FOSS projects work. They involve individual human beings, perhaps just a single person or, more likely, several people from many organizations and even different cultur... (more)

Seven Observations On Software Maintenance and FOSS

Open Source Journal on Ulitzer The November 2009 issue of Communications of the ACM (CACM) has a very interesting article by Paul Stachour and David Collier-Brown entitled “You Don’t Know Jack About Software Maintenance”. The authors argue energetically for using versioned data structures and “continuous upgrading” to improve the state of the art of software maintenance. The piece got me thinking about FOSS (Free and Open Source Software) and “continuous upgrading”. Here are seven observations on FOSS software maintenance that occurred to me as I reflected on the CACM article: FO... (more)

Xen Virtualization: Migrating 32-bit domUs to 64-bit dom0s

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 power in each machine with ever decreasing costs. Virtualization is one of the best ways to take advantage of these big changes in hardware. Currently, Xen is the most mature FOSS (Free and Open Source Software) virtualization technology. Although we love the idea of KVM, since it requires a special p... (more)

The Nature and Importance of Source Code and Learning Programming with Python

Cloud Computing Expo Last year a client asked us for advice on getting started with programming. So I thought I’d share some thoughts about programming, its relationship with FOSS (Free and Open Source Software) management and why Python is a good language for learning programming including some great on-line resources. But first I want to make sure our business-oriented readers understand the nature and importance of source code. Register Today and Save $800 ! Explore Sponsorship Opportunities ! The “source” aka “the code” provides a language in which computer users can create ... (more)

How and Why Contributing to FOSS Can Benefit Your Organization

At first glance, the ecosystem in the Free and Open Source Software (FOSS) world can seem a bit complicated. There are several ways to get software: project websites where you can download it directly, use a software management tool that your Linux distribution provides, or you may also be able to install a Linux distribution that includes everything you need right out of the box! Once you understand this ecosystem, you can find where your contributions would be most useful, and why contributing is beneficial to your organization and the FOSS community. So, where does this all b... (more)
