Comparing MySQL performance

Comparing MySQL performance, Wednesday February 09, 2005 (02:00 PM GMT) By: Tony Bourke

With the introduction of the 2.6 Linux kernel, FreeBSD-5-STABLE, Solaris 10, and now NetBSD 2.0, you might be wondering which of them offers superior database performance. In my previous article, I discussed the tools I chose to test these venerable operating systems and the methodology by which they were tested. The result is this MySQL performance comparison between OpenBSD 3.6; NetBSD 2.0; FreeBSD 5.3 and 4.10; Solaris Express (build 69); and Linux 2.4 and 2.6 (Gentoo-based). Read on for the results.

J2ME Tutorial, Part 1: Creating MIDlets

J2ME Tutorial, Part 1: Creating MIDlets by Vikram Goyal -- Java 2 Micro Edition (J2ME) combines a resource-constrained JVM and a set of Java APIs for developing applications for mobile devices. Here is a step-by-step guide to creating MIDlets, testing and deploying these MIDlets, and a look at the lifecycle of a MIDlet.

UniGreek

Randy Hoyt has made a very nice free piece of software for Greek writing...
"...UniGreek is a software tool that allows you to generate Unicode-compliant, polytonic Greek characters using a standard English keyboard. Simply type characters on your keyboad, using an easy-to-learn and standardized system called beta code, and UniGreek converts them into the proper Unicode characters that can be copied and pasted into any Unicode-compliant application. For more information, visit the About UniGreek page..."

ACX 111 WiFi

I turned again on another box to try and find a solution to the D-Link DWL-G520+ Texas Instruments ACX 111 54Mbps Wireless Interface

General


Resources


Driver

What i found out is that a lot of people have problems with other NICs that come with a new chip every 2-3 months. There is a very nice effort at: http://acx100.sourceforge.net/. My machine is a P4CPU@1GbRAM with SuSE 9.1 Personal Edition. The images above are snapshots taken from the SuSE Hardware Tool. I will try to configure it and will blog on it. I am also going to try and work with the USB D-Link module 120+. Here is an article on USB wlan configuration.

This is Dlinks' webpage on the wlan card.

No software patents banner

I was this summer at a lecture RMS held at a University in Athens and he said that gif format is patented. The banner is in gif format and not png. Should it be in png format or have I understood something wrong?

The Portable Network Graphics (PNG) format was designed to replace the older and simpler GIF format and, to some extent, the much more complex TIFF format. (See the main page or the history page for background information.) Here we'll concentrate on two major uses: the World Wide Web (WWW) and image-editing.

For the Web, PNG really has three main advantages over GIF: alpha channels (variable transparency), gamma correction (cross-platform control of image brightness), and two-dimensional interlacing (a method of progressive display). PNG also compresses better than GIF in almost every case, but the difference is generally only around 5% to 25%, not a large enough factor to encourage folks to switch on that basis alone. One GIF feature that PNG does not try to reproduce is multiple-image support, especially animations; PNG was and is intended to be a single-image format only. (A very PNG-like extension format called MNG was finalized in mid-1999 and is beginning to be supported by various applications, but MNGs and PNGs will have different file extensions and different purposes.)

For image editing, either professional or otherwise, PNG provides a useful format for the storage of intermediate stages of editing. Since PNG's compression is fully lossless--and since it supports up to 48-bit truecolor or 16-bit grayscale--saving, restoring and re-saving an image will not degrade its quality, unlike standard JPEG (even at its highest quality settings). And unlike TIFF, the PNG specification leaves no room for implementors to pick and choose what features they'll support; the result is that a PNG image saved in one app is readable in any other PNG-supporting application. (Note that for transmission of finished truecolor images--especially photographic ones--JPEG is almost always a better choice. Although JPEG's lossy compression can introduce visible artifacts, these can be minimized, and the savings in file size even at high quality levels is much better than is generally possible with a lossless format like PNG. And for black-and-white images, particularly of text or drawings, TIFF's Group 4 fax compression or the JBIG format are often far better than 1-bit grayscale PNG.)

Xfce short review

Xfce 4.2 and Goodies is a slick, very light Desktop Enviroment for the GNU/Linux OS. It is appropriate for usage with old hardware cause of its small reqs. Tested on a P66MhzCPU@16MbRAM!

Xfce - Not too big, not too small

Tomorrow I will try to use it on a regular basis on my Ubuntu box.
http://www.ubuntulinux.org/wiki/LowEndSystemSupport/view?searchterm=xfce

More on Xfce (abstract from xfce.org):

Xfce 4.2 is the first desktop environment to ship with an easy-to-use and platform-independent graphical installation wizard, which takes care of compiling and installing both Xfce and any contributed packages on your computer. Visit the os-cillation installer website for download links and instructions.
The new Xfce desktop, while still being lightweight and easy to install, offers several new and awaited features in comparison with its previous 4.0 stable release like a brand new session manager, keyboard shortcuts, a graphical desktop menu editor, multihead support (Xinerama and Multi-Screen mode), Kiosk Mode support (to lock down Xfce in cooporative environments), optional support for icons in the desktop menu, a desktop menu plugin for the panel, CUPS and BSD-LPR printing support, a new icon theme, and various other small enhancements. Moreover, Xfce 4.2 provides bleeding-edge features, like a compositing manager for xfwm4 (a manager for the new X.org Composite extension, which brings true transparency to the Xfce Desktop) and support for the XDG base directory specification (see this page for an explanation of the new file locations). A complete list of changes between Xfce 4.0 and 4.2 is available here.
