In this final installment on testing of the three part series, Brian Goetz examines another technique for smoking out bugs that violate design rules: aspects. The first two installments in this series, Part 1 covering testing in integrated frameworks and Part 2 on testing with leverage, show how static analysis tools like FindBugs can provide greater leverage in managing software quality by focusing on entire categories of bugs rather than on specific bug instances.

Unlike other open-source offerings, EnterpriseDB Advanced Server can run Oracle database applications unchanged.

This series chronicles the creation of the ultimate mashup, an application that not only stores data from different mashups but uses semantic technology to enable users to create their own mashups by swapping services, or even by picking and choosing data. In this part, Nicholas Chase introduces the concept of mashups, shows you how they work and how to build a simple version of one. Mashups use Java programming and a combination of servlets, JSP, software from the open source Jena project, and DB2's new native XML capabilities.

Last week, The One Laptop Per Child initiative put a name on their first laptop device. The new name is “Children’s Machine” or CM1, apparently taken from the title of Seymour Papert’s book of the same name (published in the early 90s.) There isn’t a signficant amount of technical update. I should mention, though, that the team has brought up Forth on the laptop recently. I used Forth at Atari Coin-op and I can attest to its ease of debugging hardware. Redhat is still slated to deliver a “skinny” version of Fedora Core to be shipped on the laptop.

Every now and again, someone will loudly proclaim that Slackware is dead. Wrong. While it's not as popular as young whipper-snapper Ubuntu, its long-time competitor the Debians, or the solid SUSE family, Slackware is still alive and well with a healthy user community.

OpenUsability, the organization of software interface usability experts, has begun taking applications for the first in a series of funded student projects. Similar to the Google Summer of Code, selected students will be paired with mentors and set to work on projects to be completed over a three-month period, with a reward of $700 upon success. Students applying now will be competing for the first such position -- an opportunity to do interaction design for the GIMP.
