How Software is Built

Interviewers: Scott Swigart and Sean Campbell.

Interviewees:Shawn Burke.

In this interview with Shawn Burke of Microsoft we asked him about:

• Shawn’s motivation for helping to make the framework source code available.
• Whether there are any limits on who gets access to the source code.
• Whether there was any internal resistance initially to providing the framework source.
• Why Microsoft doesn’t just provide a zip for the source.
• Whether Microsoft’s individual developers write code differently knowing that their actual source might be available for the world to see someday.
• Whether or not Microsoft is planning on making available other development artifacts such as test scripts, threat models, etc.
• Whether a closed source company or an open source company is better positioned to support external developers who need access to the source for a given project.

Interviewees:Blaine Wastell and Glenn Block.

In this interview with Blaine Wastell and Glenn Block of the Patterns and Practices Group at Microsoft we asked them about:

• About the Patterns and Practices Group
• What makes them different from a typical product development group
• The software development methodology they use
• Some of the things that Patterns and Practices group has produced for developers.
• The role of CodePlex for their group.

The OSI has approved the two Microsoft software licenses, the Microsoft Reciprocal License, and the Microsoft Public License.  This makes all the code on Microsoft’s CodePlex site (Microsoft’s equivalent of SourceForge) official open-source software, as much of it is licensed under the Microsoft Public License (formerly the Microsoft Permissive License).  It also means that things like Microsoft’s Ajax Control Toolkit is open-source (with the inherent ability to fork, etc.)

According to Scott Guthrie, Microsoft will make the source for the upcoming .NET Framework 3.5 available under the Microsoft Reference License. This isn’t an open-source license (i.e. you couldn’t fork the code), but it is still a “good thing” in that developers can learn from the source and have an improved debugging experience with the ability to step-into the framework code.

Update: It seems that this isn’t seen as happy news by all. There’s an article on eWeek that’s just too irrational and frothing to pass up, claiming that this is all a ploy by Microsoft to kill Mono. As Microsoft is officially supporting Novell’s efforts in porting Silverlight to Linux (on top of Mono), the evidence would indicate that Microsoft is doing this to support .NET developers, and not as some clever conspiracy to kill off Mono.

Interviewee: Jay Pipes

Jay Pipes

In this interview, we speak with Jay Pipes North American Community Relations Manager at MySQL.

We talk about:

• How MySQL Community and Enterprise servers are nothing like RedHat Fedora and RHEL.
• The nuances of MySQL licensing.
• It’s built mostly like traditional software, with 120 developers on staff at MySQL.
• But that’s changing, the worklog system has been opened to the community and they’re starting to take contributions.
• For that to happen, MySQL has to become more modular and support plug-ins.
• MySQL supports so many platforms through a portability layer, which was a lot of work initially, but now it’s pretty well baked.
• Bugs = Gold.
• The tenets of MySQL: performance, reliability, and ease of use.
• It’s easier for proprietary software to make money, it’s easier for open-source to get work done.
• And finally, how to get involved.

Phil Costa

In this interview, Scott Swigart, Sean Campbell, and Richard Bowler interview Phil Costa who is the Director of Product Management for Flex and ColdFusion at Adobe, with responsibility for product definition and strategy of the Flex product line.

Phil has a Master’s degree in English from Boston University and an undergraduate degree from Swarthmore College.

In this interview, Phil talks about Adobe’s decision to open-source the Flex SDK. In specific, Phil talked about:

• Background on the Adobe Flex SDK
• Why open-source the Flex SDK
• Risks in open-sourcing the Flex SDK
• Why the MPL license was chosen
• Advantages in open-sourcing the Flex SDK
• The risks of people forking the build
