Ask Jazz Technical Lead Dr. Erich Gamma 83 83

As IBM continues to build out Jazz, their community-oriented development site, technical lead Dr. Erich Gamma has offered to answer questions about Jazz or anything else in his realm of expertise. Among his many accomplishments, Erich worked with Kent Beck on the Java unit testing framework, JUnit, and was actively involved until JUnit 4. Dr. Gamma was also one of the fathers of Eclipse and the original lead on the Eclipse Java development tools. Feel free to fire away on Eclipse, Java, JUnit, the Rational suite, the Jazz site, or anything else you think Erich might be able to answer. Usual Slashdot interview rules apply. Update 19:05 GMT by SM: As pointed out by user Hop-Frog, Dr. Gamma is also co-author of the influential computer science textbook Design Patterns: Elements of Reusable Object-Oriented Software.

EXT4, Btrfs, NILFS2 Performance Compared 102 102

An anonymous reader writes "Phoronix has published Linux filesystem benchmarks comparing XFS, EXT3, EXT4, Btrfs and NILFS2 filesystems. This is the first time that the new EXT4 and Btrfs and NILFS2 filesystems have been directly compared when it comes to their disk performance though the results may surprise. For the most part, EXT4 came out on top."
