Open-source software is indeed vulnerable to claims of patent infringement. But lawyer Steven Frank says that doesn't mean the legal floodgates are about to open.

Novell will take the "immature" Linux operating system and turn it into a" robust, reliable and scaleable" enterprise-class operating system. Read the interview with Novell CEO, here. Update: Two more Novell-Linux articles here and here.

This is an editorial by Brad Chamberlin on how he sees Mandrake Linux's 9.1 usability. Before starting bashing the author , take note that he is a Mandrake user for many years, but he is sensitive on UI and usability issues. This user likes a clean, logical and well-thoughout experience and he simply outlines the unpolishness and incosistency that a user finds on any Linux distribution today, not just on Mandrake.

An interesting Palladium editorial is at Linux-mag, going through the pros and cons of the technology.

A few days ago we featured an interview with one of Fink's project leaders regarding their package management solution which breeds more Unix software to MacOSX. Today, we host an interview with Jordan Hubbard regarding the DarwinPorts, speaking for the DarwinPorts Team which a similar effort to bring more Unix software on Mac OS X. Jordan is currently working at Apple and OpenDarwin (while many will know Jordan as the FreeBSD co-founder).

Apple is on the verge of announcing a trio of speed-bumped eMacs, sources confirmed to Think Secret. 'Highly reliable' sources said that Apple's consumer eMac lineup will be expanded to three models at 800MHz and 1GHz, and with larger hard drives. But other changes are also in store.

The paper considers a mathematical model of the behavior of an assembly of N stars. The 'Kepler' Microsoft Windows demo application based of this model enables to perform real-time simulation of star clusters dynamics for N~=2500. Such performance rate is possible through the use of the Intel Integrated Performance Primitives (IPP) library. The paper also estimates the efficiency of the IPP application and provides an example of C-code with the IPP functions calls. Computer-simulated images of the spiral galaxy forming process, as well as the real galaxies photos, are presented.

Frank writes "Performance breakthroughs seem to come in two varieties: easy and hard. That's no platitude; the boundary between the two is surprisingly clear. Although in some cases it has taken considerable genius to realize their first application, they're easy to understand. The other kind involve careful measurement, specific knowledge, and a fair amount of tuning. Good programmers can operate in either the "hard" or "easy" mode. This article offers a paired collection of 4 hard and easy tales from real (programming) life."
