As some of you may already know, I've been in the process of setting up a new server to host my sites. My old VPS just can't handle the load anymore. Since I'm not really making a lot of money off the sites (Maybe $100 a month, if that), my budget is definitely tight. Here's how I setup a server, capable of supporting over 4,000 static requests per second, and over 1,000 PhP requests for second (Using a Joomla installation with SEF enabled). Oh, and I only spent $800 on hardware, and $50 a month for a datacenter with 100mbit up link to the internet (billed on monthly transfer). The server is great for hosting a few sites (lets say up to 20 or so), but could be setup to serve thousands of sites. So, here's how I did it.

New U.S. regulations went into effect today that could change how vendors of devices with software-defined radios (SDR) use open-source software. The new rules could impact manufacturers of mobile phones, WiFi cards, and other devices that use SDR technologies.

Are Microsoft’s patent lawyers playing possum? Or are they really as clueless about what makes open-source software tick as they seem?

An attempt to explain some of the biggest things standing in the way of the home user adopting Linux for their desktop operating system.

Ingo Molnar released version 19 of his CFS scheduler patchset, first released back in April. He noted: "The biggest user-visible change in -v19 is reworked sleeper fairness: it's similar in behavior to -v18 but works more consistently across nice levels. Fork-happy workloads (like kernel builds) should behave better as well. There are also a handful of speedups: unsigned math, 32-bit speedups, O(1) task pickup, debloating and other micro-optimizations."

By this time, you should have guessed that running KDE takes a large chunk of machine resources. Really old machines will run this latest version of KDE quite slowly. I chose it for the FreeBSD beginner because it’s a good safe place to start, with so many built-in tools. One of the most important ones up to now has been KPPP — the dialup tool. In this lesson we are going to learn how to dialup without KPPP. With that, about the only reason to keep using KDE is simply that you like it.

At this year's annual KDE conference aKademy in Glasgow, Scotland an entire day was dedicated to the use of free and open source software in schools and education. The main aim of the day, organized by the KDE Education Project, was to unite the many different diverse consumers (teachers, system integrators, students) and to share ideas, success stories and best practice. The report from the day is now available for reading - aKademy 2007: Education Day.

Zenwalk Live has been updated against Zenwalk Linux 4.6 and this LiveCD distribution now features Xfce 4.4.1 with notification support, the Xfce Thunar file manager can now handle video thumbnails, and many new Xfce 4.4 panel plug-ins have been added or updated. At the system level is GCC 4.1, Glibc 2.5, and binutils 2.17.50. Last but not least, Zenwalk Live 4.6 includes the Linux-Live scripts with LZMA enabled Squashfs support. Zenwalk Live 4.6 will cost you about 400MB of bandwidth, but it's definitely an interesting LiveCD that is worth trying out whether you're a Linux junkie or Windows user.

Polish Ministry of Internal Affairs, responsible for National Computerization project is currently working on National Interoperability Framework. The framework regulates three types of activities: Administration to Business (A2B), Administration to Citizens (A2C) and internal (A2A). In the draft version, a "right" definition of Open Standards is used. However open-source software is not mentioned at all.

Hot on the heels of JavaFX, taking on the likes of Microsoft Silverlight and Adobe Flash, Sun looks set to formally unveil its plans for Project Indiana this week and attack the Linux developer heartlands. With Project Indiana touted as a move towards a better Linux than Linux, one observer asks the 'Emperor's New Clothes' question: what's actually wrong with Solaris as is?

Performance optimization in Linux doesn't always mean what you might think. It's not just a matter of outright speed; sometimes it's about tuning the system to fit into a small memory footprint.

By his own description, Dirk Riehle is a major fan of open source software. Riehle, leader of the open source research group at SAP Labs in Palo Alto, California, spends countless hours theorizing about the economics of this emerging software trend. He’s the author of The Economic Motivation of Open Source Software, a scholarly article that describes significant shifts in the software business. Datamation spoke with him about how these shifts are shaping the pay levels of open source developers.

Recently Joseph Conn wrote an excellent article on VistA. A Modern Healthcare reader replied with a comment titledAntiquated system slowing EHR transformation which essentially argued that VistA was holding health IT back... because its old. Thankfully Modern Healthcare has also published my replyVistA: You say 'antiquated;' I say 'proven'. I offer more thoughts on the subject over atGPLMedicine.org in my post'antiquated' vs 'proven' -Trotter

While the new Federal Communications Commission (FCC) regulations about software-defined radios don't really restrict independent FOSS developers, the rules are"more conservative than is necessary" because of perceived security issues, according to a white paper released today by the Software Freedom Law Center (SFLC).
