Bob Lee, co-author if Bitter EJB, has a quick concise summary of AOP in his blog on Java.net.
Interesting OnJava.com article on side-effects of using static initializers
O’Reilly’s OnJava.com have a great article on their site discussing the side effects of using static initializers in your Classes, and describes how accessing static members if different ways may effect when the static initializers are executed.
I’ve run into a couple of these before, particularly the fact that initializers for static members are executed in the order they appear in the code – this is something you should be aware of if there are dependencies between the static variables and or their initializers.
XP Pair Programming thoughts
This blog entry caught my eye on JavaBlogs, discussing whether Pair Programming is the “magic silver bullet” or not.
In my opinion, I believe there are real gains to be had from pair programming, however from my own informal experience it does improve code quality but at the cost of efficiency.
I think it takes a lot longer to produce the same piece of code with two heads as there is a lot of continuous discussion that takes place while the code is being written. That said, the interaction and discussion can produce better and more appropriate solutions to problems.
I think its a hard balance to get right and depends very much on the successful pairing and what you intend to gain from the pairing. For example, the less experienced developer paired with the more experienced developer can result in a valuable knowledge share and the less experienced developer picking up valuable skills. This is a definite benefit to the team. However if the pair consists of two more experienced developers, you might find that more time is wasted debating purely academic issues than actually producing code, at the cost of not having that second developer producing code of his own or helping with other less experienced developers.
Microsoft to remove features from Longhorn to meet expected ship date
Microsoft have announced that previously expected features will be removed from Longhorn in order to meet the expected ship date of end of next year (2005).
Longhorn was expected to be the first release of Windows to include the radically new WinFS file system, supposedly to be based ontop of a database engine such as SQL Server to add more powerful search capabilities and indexing of users files.
