SilentBob4 writes "The PostgreSQL database project has recently released Version 8.0, which was received with quite some fanfare, mostly due to its first-ever Windows port. Mad Penguin talked with Josh Berkus, one of the core team members, to find out how 8.0 has fared since its official release on January 17, 2005. Full interview."

norburym writes "PHP 5 Power Programming is the latest in the Bruce Perens Open Source series of technical books focusing on Linux and Open Source technologies. Prentice Hall PTR publishes each book under an Open Source book license and provides free electronic versions several months after each book's publication. This particular book also includes a link to a 90-day version of Zend Studio, an IDE for PHP which also includes a PHP debugger, code analyzer and code profiler. PHP 5 Power Programming was written by Andy Gutmans (co-creator of PHP versions 3 through 5), Stig Bakken (creator of PEAR -- the PHP Extension and Application Repository -- a framework and distribution system for reusable PHP components) and Derick Rethans (leader of the PHP QA team). The move to PHP 5 has begun and this volume will prepare power users with the necessary knowledge and tools to make the transition from v.4 easy. Gutman et al. provide PHP engineers and experienced web programmers a proficient introduction to the enhancements and improvements in PHP 5." Read on for the rest of Norbury-Glaser's review.

The contest is designed to award and showcase innovative new open source applications that are designed or optimized specifically for Linux running on the PPC architecture. The contest also awards ports of existing applications from a predetermined list. Contest prizes include Segway HTs, Apple Power Mac G5s, and cash awards. "

jcr13 writes "OCaml is nearly as fast (or sometimes even faster) than C, right? At least according to the Computer Language Shootout [alternate] (OCaml supporters often point to these shootout results). My results on a real-world programming problem (optimizing a garden layout using dynamic programming) disagree. On one particular problem instance (a garden of size 7x3), my C++ implementation finished in 1 second, while the OCaml implementation was still running after 16 minutes. Bear in mind that my OCaml implementation was dramatically faster than my equivalent Haskell code. It seems that if you program using a functional style in OCaml (which I did, using map, filter, and other recursive structures in place of loops), it is quite slow. However, most of the shootout OCaml programs rely heavily on OCaml's imperative features (unlike Haskell, OCaml doesn't force you to be a functional purist). If you write OCaml code that is isomorphic to C code, it will be fast---what about if you use OCaml the way it was meant to be used?"

Reducer2001 writes "News.com is running a story previewing GCC 4.0. A quote from the article says, '(included will be) technology to compile programs written in Fortran 95, an updated version of a decades-old programming language still popular for scientific and technical tasks, Henderson said. And software written in the C++ programming language should run faster--"shockingly better" in a few cases.'"

sysadmn writes "Yet another reason not to count Sun out: Chip Multithreading. CMT, as Sun calls it, is the use of hardware to assist in the execution of multiple simultaneous tasks - even on a single processor. This excellent tutorial on Sun's Developer site explains the technology, and why throughput has become more important than absolute speed in the enterprise. From the intro: Chip multi-threading (CMT) brings to hardware the concept of multi-threading, similar to software multi-threading. ... A CMT-enabled processor, similar to software multi-threading, executes many software threads simultaneously within a processor on cores. So in a system with CMT processors, software threads can be executed simultaneously within one processor or across many processors. Executing software threads simultaneously within a single processor increases a processor's efficiency as wait latencies are minimized. "

RealPlayer and MediaPlayer feeds will be available at 10am EST, according to the NPR.org site." Indeed they are.

daria42 writes "More than 100 Microsoft Most Valuable Professional (MVP) developers have signed a petition demanding the software company reconsider plans to end support for Visual Basic in its "classic" form. Developers claim the move could kill development on millions of Visual Basic 6 (VB6) applications and "strand" programmers that have not trained in newer languages."

Sam writes "The OpenBSD cvs server has a failing RAID array. Users of the projects on that array: OpenBSD, OpenSSH, OpenBGPD, OpenNTPD, and the upcoming OpenCVS are all invited to contribute towards the $12,500 cost of a suitably high-spec replacement.

douthitb asks: "I have recently started work as a contractor with a company developing/improving an application for exchanging large amounts of data. The current solution exchanges data via XML, but the data itself is stored in a SQL Server database. There is a concern about the overhead involved with wrapping and unwrapping the XML to get the data in and out of a relational database. The proposed solution is to use Tamino, an XML-based database. Neither I nor any of the other developers have any experience with Tamino, but the desired result is to remove the bottleneck of converting the XML back and forth. Does anyone have experience using Tamino (or any other XML-based database)? What benefits and/or difficulties did you have in using an XML database, as opposed to its relational counterpart? How large of a learning curve should be expected with a product like this? Do XML databases really live up to the hype? A similar topic was discussed on Slashdot way back when, so I was hoping to get some more up-to-date feedback on the subject."

Node and Edge asks: "Many interesting problem domains involve some form of graph-based or graph-like information: network activity visualizations; social software; workflow management; P2P software development; and version control with branching, just to name a few. It is notoriously difficult for people to visualize a graph structure - unless it happens to be a strictly hierarchical tree-like structure, such as what we know from file-system explorers. Now, with all of that said, what graph libraries can you recommend? The following criteria apply, though they're not absolute: Java or Java bindings; simple to use for simple applications; and polished, extensible UI components. I'm familiar with JGraph, JUNG, Prefuse, OpenJGraph, Tigris GEF, Eclipse GEF, Graphviz, but have not had a chance to evaluate them all. Have you used any of these extensively? If so, can you provide any constructive advice? If not, can you recommend something else, ?"

One of the more interesting tech pieces that came out this week has been Hindsight [PDF]. Hindsight is made by Virtutech and is billed as the "the first complete, general-purpose tool for reverse execution and debugging of arbitrary electronic systems." The demos were received extremely well and it just looks cool.

sebFlyte writes "After the reports of problems with Firefox' development earlier this week there are now rumblings about more serious problems with the Mozilla Suite. Some developers want to spin the suite out as a community project that the foundation has no responsibility for, and others want to create a Firefox Foundation to deal with the success of the standalone browser."

r3lody (Raymond Lodato) writes "Anyone who has been working on the *nix platform has had a brush with Perl, the scripting language whose acronym (depending on who you ask) could mean Practical Extraction and Report Language, or Pathologically Eclectic Rubbish Lister. In either case, there is a distinct difference between learning to use Perl, and learning to use it well. In my opinion, the best way to learn any language well is to see how others have used it to solve problems. One of the foremost experts in the use of Perl, Randal L. Schwartz, has been writing columns since March of 1995 on the use of Perl in the real world, and has provided us with 6 books and over 200 columns with many examples on how Perl is used." Read on for the rest of Lodato's review.

An anonymous reader writes "LinuxDevices has published the full keynote address delivered at the Embedded Systems Conference 2005 by Wind River CEO Ken Klein. The hardnosed speech presents a five-point action plan for device software developers who are interested in keeping their jobs -- as opposed to becoming "roadkill," as Klein puts it. The speech is decidedly short on warm fuzzies, but does offer a few practical considerations for engineer job survival in the post-recession era."
