The Secret World of ReiserFS
Newsfactor looks into the secret world of ReiserFS.
"Hans Reiser created filesystem benchmarking tests designed to be fairly representative of the file-size distribution of most users. About 80 percent of the files in the benchmark are 8K or smaller, 80 percent of the remaining files are 80K and smaller, and the remainder are 800K and smaller. "Reiser4 does quite well on all benchmarks," Reiser said. "With [Reiser4], we took five different technical gambles, and all of them worked. The result is very high performance.""

Firefox 0.8
lxer reviews Firefox 0.8.
"All told, this browser is an excellent piece of engineering and the Mozilla team must be very satisfied with the work that they are contributing to the internet community. It takes a lot to get me to switch software packages (I'm still using WindowMaker!), but after over 2 years I have finally found my new web browser."

An Oracle Instructor’s Guide to Oracle10G
Dbazine brings us: An Oracle Instructor’s Guide to Oracle10G which tells us that Oracle has added what I am going to call Do-Over to its database.

"Until Oracle10G that is… Oracle10G’s Flashback Database feature provides a new tool in the DBA’s recovery toolbox. Flashback Database allows the DBA to “roll back” a table, set of tables or the entire database to a previous point-in-time."

Setting up K12LSTP4.0 Linux Terminal Server
Linux Gazette tells us how to set up aK12LSTP4.0 Linux Terminal Server. "K12LTSP is based on RedHat Linux and the LTSP terminal server packages."
"Basically K12LTSP allows you to take older machines and turn them into usable thin clients for a faster server. The applications run on the terminal server (your fastest machine) . Workstations (your older machines) are like thin clients. They don't have software or need hard drives. In other words, take an old, slow, antique machine and give it new life instead of throwing it into the trash bin."

Linux 2.6 Scales the Enterprise
Linux Insider takes a look at Linux 2.6 performance.
"Across the board, the v2.6 kernel outperformed the v2.4 kernel in the database tests, especially on the Itanium box, where it posted a speed increase of 23 percent (a 519-second lead) over the v2.4 kernel. On the Xeon platform, v2.6 showed almost a 13 percent gain (a 200-second lead) over v2.4. And on Opteron, it registered a 29 percent speed increase (a 415-second lead) over v2.4. The most impressive individual test was table inserts, showing the v2.6 kernel providing a 10 percent performance increase (with a 100-second lead) over v2.4 on Xeon, with even better results found on the Opteron and Itanium platforms."

OpenGL Development Tools
Apple tells us about using OpenGL development tools.
"You are encouraged to employ the OpenGL Profiler throughout the development process of a 3D graphics application. Regularly lifting the hood and tuning the engine has countless benefits that can help eliminate performance bottlenecks, preemptively squash bugs that may be hiding in dark corners, and generally make an OpenGL application run more smoothly."

Blue Linux!! The Truth
Helfrez Gama has written up a short but informative post "To put to rest all the rumbling and rumours of whether or not their is an internal version of Linux being used and developed at IBM."

Getting to Know Gnome
Acts of Volition takes a look at the Gnome desktop environment and compares it to Mac OSX and Windows XP.
"The single greatest weakness I see in using Linux as a desktop is difficult to articulate: the “feel” of the graphics just isn’t there yet. This includes the smoothness and speed with which menus open, windows are moved, etc. Don’t get me wrong, Gnome is easily on par with Windows XP as far as graphics and visual on my laptop (a relatively new P4/2Ghz/1GB-RAM). It’s Mac OS X that has taken a leap forward in this area. The PDF and OpenGL based graphics rendering in Mac OS X gives an overall feel of speed, powerful, and stability that makes Windows and Linux feel like they’re made of paper mache in comparison."

Securing Intranets with IPCop
Sys Admin Magazine tells us how we can use IPCop on our network.
"IPCop is an ideal, low-budget solution for intranets that require comprehensive network security. On the surface, IPCop is an integrated Web interface with a formidable assortment of security tools. Inside, IPCop is actually a scaled-down Linux distribution outfitted and optimized to serve as a firewall. IPCop consists of several core components:"

Kernel Comparison: Web Serving on 2.4 and 2.6
Many improvements have been made in the Linux 2.6 kernel to favor enterprise applications. This article presents results from the IBM Linux Technology Center's Web serving testing efforts, comparing the Linux 2.4 and 2.6 kernels from various aspects. The highlights here are the key enhancements in the 2.6 kernel, the test methodologies, and the results of the tests themselves. Bottom line: the 2.6 kernel is much faster than 2.4 for serving Web pages, with no loss in reliability.

High Availability and Redundancy
Linux Magazine tells us about high availability and redundancy in: Highly-Affordable High Availability, Linux Virtual Server Clusters, and Data Redundancy By DRBD.
"Although high-availability means different things to different people, here it refers to highly-available clusters. An HA cluster is a set of servers that work together to provide a set of services. In an HA cluster, services don't belong to any one server in the cluster, but to the cluster as a whole. If one server fails, its services are provided quickly and automatically by another server."

Slax - an OS in Your Pocket
Guilinux takes a look at Slax.

"My review of Slax is from the inexperienced eye. Although I have been using Linux on the Desktop for years, Redhat and Mandrake mostly, I am totally new to Linux installs and any technical aspect of Linux. The extent of my knowledge is in using the basics of the Linux desktop (who says Linux isn't ready for the desktop?) mostly through both KDE and Gnome."

Linux Untethered
Linuxdevcenter tells us about cellular networking.
"In the United States and most of the world, the choice of providers usually comes down to GSM (Global System for Mobile communications) and CDMA (Code Division Multiple Access). Other protocols are still in use, but these are the leaders. GSM and CDMA have corresponding data protocols. With GSM, a cellular provider can support GPRS or EDGE ..."
