lwb writes "For those of you interested in interesting hard-core C programming tricks: Adam Dunkels' protothreads library implements an unusually lightweight type of threads. Protothreads are not real threads, but rather something in between an event-driven state machine and regular threads. But they are implemented in 100% portable ANSI C and with an interesting but quite unintuitive use of the switch/case construct. The same trick has previously been used by Simon Tatham to implement coroutines in C. The trick was originally invented by Tom Duff and dubbed Duff's device. You either love it or you hate it!"

MagLev writes "MySQL, especially version 5.0, is popping up on the radar screens of database gurus who built their reputations and book sales using other SQL databases. Ken North, who did those ODBC performance benchmarks for Oracle, Sybase, and DB2, wrote a recent article about MySQL 5.0. The article profiles mission critical database software and discusses how well MySQL 5.0 fits the profile. It gives good marks to MySQL, except for Java and XML integration."

sereda writes "Deskzilla released their desktop client for the Bugzilla bug tracking system today. The Deskzilla system promises to deliver features for greater productivity and improved working environment for the users of Bugzilla." There are also a few screenshots posted on their site.

Da Massive writes "Sun is looking seriously into the database market - namely PostgreSQL. It says Oracle and IBM and even Microsoft licensing fees are way too expensive for the average punter. This from John Loiacono, executive vice president of software: "We're not going to OEM Microsoft but we are looking at PostgreSQL right now," he said, adding that over time the database will become integrated into the operating system."

An anonymous reader writes "As reported on SiliconBeat, Marc Andreessen has finally lifted the covers off his latest project: an applications structure called Ning, which makes the development of social websites like thefacebook.com and match.com more accessible. See TheGlu and Dating for examples of Ning in action."

juanescalante asks: "I graduated with a B.S. in Computer Science about 9 months ago and I have been working as a software developer for more than a year now. I keep looking for ways to improve myself in what I do, and seeking to gain knowledge from those who have a lot more experience than me. I've been reading books like 'Code Complete' and 'The Pragmatic Programmer' and I would also like to subscribe to a couple of great magazines. So, to all you experienced developers, which are the top software development magazines?"

cj2003 writes "Mark Shuttleworth has released a FAQ about Ubuntu's Direction and Intent. It comments on the discussions of funding, of being a Debian-fork or not, of the strange names, and many other 'hot topics' relating to Ubuntu. In his own words: 'This document exists to give the community some insight into my thinking, and to a certain extent that of the Community Council, Technical Board and other governance structures - on some of the issues and decisions that have been controversial.'"

mschaef writes "Announced on Bill Clementson's Blog, Brad Parker has stated that he has 'permission from MIT to release all the LISPM source code with a "BSD like" source license.'" Zach Beane has also set up a torrent for easy download.

An anonymous reader writes "There's an article by Jason Miller on innovation in Unix that talks about OpenBSD's new heap protection mechanism as a major boon for security. Sounds like OpenBSD is going to be the first to support this new security method."

An anonymous reader writes "Logical partitioning provides POWER processor-based servers with the capability to do server consolidation and optimize system resources. Dynamic logical partitioning enhances this capability by providing control of the allocation of the resources without impacting the logical partitions availability. Linux on POWER supports dynamic LPAR for changes to physical I/O, virtual I/O, and processor resources."

auckland map writes to tell us about an interesting debate that is being featured on KernelTrap. Linus Torvalds raised a few eyebrows (and furrowed even more in confusion) by saying "A 'spec' is close to useless. I have _never_ seen a spec that was both big enough to be useful _and_ accurate. And I have seen _lots_ of total crap work that was based on specs. It's _the_ single worst way to write software, because it by definition means that the software was written to match theory, not reality."

dogma01 writes "Parrot the virtual machine for Perl6 and other dynamic languages has released version 0.3.0. If interested you can also help support Parrot development by donating to The Perl Foundation or by getting involved with development."

An anonymous reader writes "In most development organizations, software reuse occurs on a regular basis in at least an ad hoc manner. Code is shared across projects in an informal manner. SOA provides the mechanism for more formal reuse. So what are the issues? This article examines some of the challenges associated with the creation and usage of reusable services."

George Maschke writes "Yesterday, lead developer Corey Chapman announced the release of Yet another Bulletin Board 2.0. The new version of this free, open source software adds many new features and improvements, bringing its feature set more in line with that of rival phpBB. YaBB 2.0 may also be downloaded directly for a quick look."

An anonymous reader writes "Best-selling author Steven Levy has a new profile of techincal publisher Tim O'Reilly over at Wired." From the article: "... O'Reilly himself has operated for years under the radar. Most nontechies, if they know him at all, know him by the eponymous name of his publishing company. It has a 15 percent share of the $400 million computer-book market but casts a much bigger shadow. O'Reilly books tend to colonize entire sections at Borders and Barnes & Noble, their distinctive cover design as recognizable as the Tide circle on a box of detergent or the Apple logo on the lid of a PowerBook. In serif type over a glossy white background, there is the title, often naming a computer language or protocol familiar to codeheads and gibberish to everyone else (JavaServer Faces; Essential CVS; Using Samba, 2nd Edition). The illustrations are realistically rendered pen-and-ink drawings of animals."

An anonymous reader asks: "The argument regarding the principle nature of hacking - be it an art or a science is not a new one. This paper hopes to discuss both the meaning of the term 'hack' and the underlying arguments for it being defined as an art or a science, in reference to the base principles and basic methodologies of the discipline. So in your opinion, is hacking art or science?"

JDStone writes to tell us eWeek is reporting that claims of OpenSSH not being an 'enterprise-class product' by SSH Communications, the creators of SSH, is being met with a great deal of resistance. Theo de Raadt, of OpenBSD fame and a member of the OpenSSH development team was quoted saying "OpenSSH is built into all Unix and Linux vendor operating systems, and is also built into almost all larger managed network switches, from Cisco through Foundry. It comes on Linksys and D-Link wireless and security routers too."

On Monday, we asked you for questions for industry legend Sid Meier. Today, we're asking for question to put to the folks behind the technology of Civilization IV. Besides the actual coding and development that went into the game itself, the team has made Civilization IV infinitely moddable through technologies such as XML, Python, and a fully developed SDK. Led by lead designer Soren Johnson, the team will answer your questions about the creation of the fourth chapter in one of the most influential game series out there. So, fire away with your questions. One per comment, please, and keep them topical. We'll pass the ten best questions to Johnson and the team, and the answers will be posted as soon as we have them in our hands.

An anonymous reader writes "LinuxDevices.com has an article about a development kit for prototyping device displays based on electronic paper technology. The kit includes a 170dpi, 6-inch (diagonal) SVGA (800 x 600) EPD (electronic paper display) module supporting four shades of gray, and a small computer module that runs the display. EPDs provide bright, high-contrast, thin, lightweight displays that remain legible under 'any lighting condition' -- much like newsprint. Once an image has been 'printed,' no power is needed to hold it."

commonchaos writes "Recently a company named Zimbra has come out of nowhere and released an open source Exchange replacement. The exciting part is a front end that uses AJAX. There is an impressive flash demo, you can download the source or try out a "live" version of the code yourself." Interestingly, this open source system seems to be very similar to the recent Yahoo announcement covered on Slashdot.
