CFS Digressions

"In the patch you really remove _a_lot_ of stuff," commented Roman Zippel in his reaction to Ingo Molnar's latest updates to the Completely Fair Scheduler. Roman has been consistently critical of Ingo's efforts, asking questions and criticizing Ingo's feedback. He continued, "you also removed a lot of things I tried to get you to explain them to me. On the one hand I could be happy that these things are gone, as they were the major road block to splitting up my own patch. On the other hand it still leaves me somewhat unsatisfied, as I still don't know what that stuff was good for."

Application Acceleration and WAN Optimization Fundamentals

To quote from the "Who Should Read This Book" section: "This book is intended for anyone who is interested in learning about the foundational components of application acceleration and WAN optimization, including IT directors, network managers, application infrastructure engineers...". Ok, I get the idea and hopefully so do you. In other words, please have an admin level background and skills if you want to understand what's going on here. The real goals of this book are to instruct network engineers as to the ins and outs of this technology and to illustrate why implementing this solution is value added in the corporate environment.

Loop-based Music Composition With Linux, Pt. 1

Loop-based music composition is the practice of sequencing audio samples to create the various parts of a musical work. A sample may contain only a single event such as a bass note or cymbal crash or it may contain a measured pattern of events such as a drum beat, a guitar chord progression, or even an entire piece of music. The former type is sometimes referred to as a"one-shot" sample, while a longer sampled pattern is often simply called a loop.A loop is usually created at a specific tempo in a precise time period (musical beats and measures) for exact concatenation with other loops. Sequencing a series of timed loops creates realistic tracks that can convince a listener that he or she is listening to a part specifically performed for the piece.

Speeding Up Perl Scripts With SpeedyCGI/PersistentPerl On Debian Etch

  • HowtoForge; By Falko Timme (Posted by falko on Sep 14, 2007 7:20 PM EDT)
  • Story Type: Tutorial; Groups: Debian
This tutorial shows how to install and use SpeedyCGI (also known as PersistentPerl) on a Debian Etch system. SpeedyCGI is a way to run Perl scripts persistently, which can make them run much more quickly. It keeps the Perl interpreter running, and during subsequent runs, this interpreter is used to handle new executions instead of starting a new Perl interpreter each time.

30 days with JFS

The Journaled File System (JFS) is a little-known filesystem open sourced by IBM in 1999 and available in the Linux kernel sources since 2002. It originated inside IBM as the standard filesystem on the AIX line of Unix servers, and was later ported to OS/2. Despite its pedigree, JFS has not received the publicity or widespread usage of Linux filesystems like ext2/3 and ReiserFS. To learn more about JFS, I installed it as my root filesystem. I found it to be a worthy alternative to the bigger names.

Linux to get the boot at US Army Corps of Engineers?

According to an anonymous source working at the Geotechnical & Structures Lab of the US Army Corps of Engineers in Vicksburg, Miss., a committee of government employees and contractors at Vicksburg is considering a new IT policy which will force everyone to move to Windows XP if they are not already running it, and to port all applications save one currently running on Linux to Windows. The lone exception would be moved to Solaris.

Empowering Vim Editor

Vim is the most advanced editor in linux/unix world. But its default settings are according to the vi editor hence hides its tremendous capabilities. Some times Vim is the only editor which we can use, like in remote header less system or in system which intentionally avoid graphics to provide its full strength to the servers daemons. What ever may be the situation; vim can be configured in such a way that specifically addresses all the features just we need. Vim reads the .vimrc from the home directory. Once we configure the .vimrc according to our requirements; editing by Vim will simply be a great joy. I have written this document to show you amazingly useful features of the vim editor in console mode and how a properly configured .vimrc makes text editing with Vim a peace of mind.

Digital security with GnuPG plugins

The GNU Privacy Guard (GnuPG) allows you to encrypt, decrypt, sign, and verify communications and data, as well as create and manage the keys needed for these tasks. It is a full, open source implementation of the OpenPGP Standard (RFC2440) and is integrated into many Linux applications ranging from clipboard applets to instant messaging clients. These applications make it easy to use GnuPG for digital security in the GNOME desktop environment.

Whitelists and Blacklists

"It turns out that USB devices suck when it comes to powermanagement issues :(" lamented Greg KH in posting some patches to handle USB autosuspend problems. He noted that the patches were intended for inclusion in the upcoming 2.6.23 kernel, "a number of patches have been submitted near the end of this kernel release cycle that add new device ids to the quirk table in the kernel to disable autosuspend for specific devices. However, a number of developers are very worried that even with the testing that has been done, once 2.6.23 is released, we are going to get a whole raft of angry users when their devices break in nasty ways." He proved an example, "it seems that almost 2/3 of all USB printers just can not handle autosuspend. And there's a _lot_ of USB printers out there..."

KDE ported to Nokia's Linux-powered Web tablets

A community developer has ported Linux's KDE desktop environment to Nokia's Internet tablets. The port appears to run on both the N800 and -- with the addition of an RS-MMC card upgrade -- the older 770 tablet. The port actually was released back in March for the N800. However, it got a new round of attention this week, when a blogger posted instructions on installing it on the older 770. "It purrs like a kitten, believe it or not," the post enthused.
