In the meantime, soft changes can significantly cleanse our Inboxes:

The real solution here is to move people beyond email silos wherever and whenever possible.

• Broad kudos? Post it on a feedback forum or your blog.
• Need an urgent, immediate answer? Pick up the phone and call.
• Got something that needs a lot of touchy feely discussion? Set up a face to face meeting.
• Discussing a particular topic or product? Post it on a public message board.
• Is this more of a friendly, social thing? Try using a social network like Twitter or Facebook.

Coding Horror

Well it’s now 2009, time to get a real image host. About to fire up S3Fox and get to work

Microsoft Research applied this notion to the study of  software engineering as a whole In Exploding Software-Engineering Myths,   MSR explores a number of research projects carried out with the intent of applying cold empirical evidence to the field of sofware development.

A few take aways:

1. More Isn’t Always Better
   1. “It is more beneficial to achieve higher code coverage of more complex code than to test less complex code at an equivalent level. ”
2. Write Test Code First
   1. “The research team found was that the Test Driven Development (TDD) teams produced code that was 60 to 90 percent better in terms of defect density than non-TDD teams. They also discovered that TDD teams took longer to complete their projects—15 to 35 percent longer.”
3. Proving the Utility of Assertions
   1. “The team observed a definite negative correlation: more assertions and code verifications means fewer bugs.”
   2. And interestingly, “The research team believes that enforcing the use of assertions would not work well; rather, there needs to be a culture of using assertions in order to produce the desired results.”
4. Organization Structure Does Matter – a lot
   1. “Organizational metrics, which are not related to the code, can predict software failure-proneness with a precision and recall of 85 percent.”
5. Geographical Distance Doesn’t Matter – much
   1. Researchers asked engineers who’d they’d prefer to talk to when faced with issues: “Most people preferred to talk to someone from their own organization 4,000 miles away rather than someone only five doors down the hall but from a different organization. Organizational cohesiveness played a bigger role than geographical distance.”

Now Mr. Murdoch believes you’re using an antiquated browser and doesn’t mind you reading his content. Enjoy!

This trend is a good thing. It’s streamlining the way people communicate and share information.

MySQL, the free open-source database, was purchased by Sun for $1 billion back in 2008 .  MySQL is a textbook example of what Clayton Christensen dubs a  “Disruptive Technology”. In The Innovator’s Dilemma Christensen talks at length of how lesser technologies, in low-return markets, have kept a steady upward trajectory eventually intersecting the major players (Oracle). This often times catches big firms off guard, only responding once it’s too late. MySQL is being deployed in more sophisticated situations, and could conceivably start to intrude on Oracle’s high end market. (Facebook is currently the largest deployment of MySQL).

Obviously the aquisition of Solaris and Java, at a bargain, was Oracle’s primary motivation. But MySQL was icing on the cake.
