I have used some of the techniques he discussed in his presentation to have SQL generate SQL, but one thing I had not thought of doing was to use the CHR function to make scripts more readable.

A colleague recently asked me, "Have you noticed that the better developers we've worked with are also fast typists?" I acknowledged that I had noticed relatively quick typing speed to be a common trait of most of the best developers that I know.

Groovier Java TimeZone ID Handling

dmarx — Thu, 25 Feb 2010 00:40:00 -0500

Many Java developers are not fond of Java's standard APIs for handling Dates and Calendars. In fact, it is difficult to think of examples from the Java standard APIs that better illustrate the mistake of allowing ultimate and mostly unused flexibility to result in an unnecessarily high degree of pain for the vast majority of users of the API.

Playing with Jersey/JAX-RS Method Designators

dmarx — Mon, 15 Feb 2010 10:04:00 -0500

There is a part of me that likes to try things just to see what happens. If I read something that says, "Never do this," I have a hard time not doing just that thing if I believe doing so comes at no significant cost. There can be value to this approach when I learn about the results associated with an improper action and can then more readily recognize the underlying cause when I inadvertently cause the same problem myself or see a colleague dealing with the same effects.
