Who is an open letter really addressed to and what is its purpose. Recently there has been an explosion of open letters. Sun's open letter to Eclipse, Eric Raymond's two letters to Sun, and IBM's letter to Sun. In today's Weblogs , John Mitchell's Sun to meet with IBM on open-sourcing Java? links to an article which promised an open response from Sun yesterday. Why were the letters signed...
Have you ever had an idea in your head that you describe to someone else to implement. Usually when you see what they've done you say "no, that's not it". Not so with Miky Vacik. Miky is the graphic designer who has helped shape the look and feel of java.net. We would describe what we were thinking for a graphic for an article or for the look of the homepage and Miky would come back with...
Kathy Sierra started a discussion on the Studio B CBP list by suggesting rather than speculating about which technical topics will be hot in the future, we should think instead about who the readers might be. Chris Adamson links to her post in today's Weblogs. In The Kids Are Alright , Chris is struck by Kathy's observations on the impact of "the technical immersion of the next generation"...
Uncle Bob notes that the Dependency Inversion Principle and the Domain Driven Design concept of Layers seem to contradict each other until you introduce another dimension. We link to his blog entry Layers, Levels, and DIP in Also in Java Today . Bob Martin begins by describing Eric Evans Layers from Domain Driven Design: UI--->App--->Domain--->Infrastructure Bob then reports that "DDD...
Dave Thomas and Andy Hunt use a gardening metaphor for programming. Too often, authors use construction to describe programming. In part two of Bill Venners Pragmatic Programmers Interview, Thomas explains that "We want people to view software as being far more organic, far more malleable, and something that you have to be prepared to interact with to improve all the time." Building...

You can read the SourceCast 2.6 Release Notes for full details. The main features included an improved search utility that can search for any artifacts except those in version control. Issuezilla has been renamed to Issue Tracker and more...
You may be able to view the current status of your JavaOne proposal just by viewing the HTML source for your session page. Warning: This is a hack. Although you are able to view a field marked "status" in your record, we don't know what this field actually means. Also, we don't know if all records start out as declined and are then promoted and we don't know if changes will be made before the...
"For server-side applications, when integrated with Web tier containers compatible with Servlet 2.3+, Velocity provides a viable alternative to JSP technology that can enforce a clean separation of presentation logic from application business logic." We link to Sing Li's developerWorks article on the Velocity Template engine in Also in Java Today . He begins with a standard mail merge type...
This discussion on whether or not your Java applications should look like native applications continues to spark a lively debate. In fact, a bit to my surprise, Chris Adamson's most recent blog entry on the topic, As Your Users Like It has four times the number of responses as yesterday's pointer by Ron Hitchens to ESR to McNealy: Let Java Go. Not that I think we can derive much from two...
"Of the 238 JSRs out there (at last count), there are zero in the GIS space. That should tell you that we're at the very beginning of the curve here. The types of applications that we'll be able to produce using GIS integration will be just astounding." Sue Spielman and Tom Whitehill make this observation towards the end of Java and GIS, Part 1: Intro to GIS. This java.net featured article...
