"One of the most important considerations in choosing an operating system for a new embedded platform is how long it takes to port the operating system to the hardware. If your hot, new product's hardware is six months ahead of the curve, but it takes you six months to port the software, you've lost your hardware advantage." Alistair Crooks, engineering director at Wasabi Systems, writes for EETimes.

Independent consultant Thomas E. Besemer writes for Embedded.com: "Is embedded Linux viable? You bet. Is it free? No way. If time-to-market matters, you get a lot from companies like Wind River with stable environments, or perhaps the current embedded Linux vendors." The December's article is accompanied by a number of insightful comments, and an additional response by the author.

The NetBSD Project announced that NetBSD 1.6.1 has been tagged and the release engineering process has begun.

From the OpenBSD Journal: In his post, Theo deRaadt gives a brief technical overview of the four major security changes in OpenBSD: POSIX page protection schemes, WorX, read only segments, and Propolice. Not all of these are on all platforms, but every platform has some protection. To quote Theo in his message, "We feel that these 4 technologies together will be a a royal pain in the a$$ for the typical buffer overflow attacker."

Until now, Sun Microsystems had a hands-off approach to the implementation of Java on mobile phones, which resulted in a chaotic and fractured Java implementation industry-wide, as different companies went their own way. Sun has taken the reigns and had proposed a road map, called "Java Technology for the Wireless Industry" or JTWI.

According to heise.de and news.com, AMD finalized their CPU roadmap this Friday. Opteron is scheduled for April, Athlon 64 for September. The Barton core will debut on Februar 10th in the Athlon XP 3000+. The Barthon increases the L2 cache from 256 (Thoroughbred-B) to 512 kByte, and will probably run only with FSB333. A Athlon XP 3200+ will probably appear by the middle of the year.

Why, you might ask, would anyone want to build their own operating system? It's really about being in control and knowing what's going on.In the next few paragraphs I'll explain what motivated me to take on this project, the recipe I used, and what I like about it.

Well, we all have used Unix, in one form or another (maybe even through embeded products). But which one is your favorite flavor of Unix-based/Unix-alike OSes? Read more and vote! Update: SHAME on you, who ever you are: Messing/hacking with go2poll's code and altering the results in favor of FreeBSD. By doing so, you are doing MORE BAD than good to your favorite platform.

A Sun-led Java standards group today will announce specifications designed to bring Java's write-once run-anywhere promise closer to reality for wireless handsets.

According to a PC World article, not only is built-in 802.11b wireless capability becoming the must-have feature for higher-end notebook computers, but vendors are starting to use dual-band chipsets that support both the widespread 802.11b standard and the faster 802.11a. 802.11a operates at 5GHz with maximum throughput of up to 54 mbps, compared to 802.11b's 2.4 GHz/11 mbps.

"Software is big business. Every year, consumers spend over a hundred billion dollars purchasing shrink-wrap software. For you as a developer, shareware is a cheap, effective means of marketing and distributing your software. Shareware lets the public redistribute your software for free, then pay a registration fee if they like it. Today, nearly all software companies provide some form of free trial version of their software." Read the article at MacDevCenter.

AMD executives reiterated that the company is focusing on the server version of the Opteron processor, but that the 64-bit Athlon 64 will still appear in 2003."You saw our financials; I'm not going to lie to you. It doesn't make a lot of sense to build a new processor for a niche market," said John Crank, senior brand manager for desktop product marketing for AMD's Computation Products Group. Although PCs certainly dominate the computing landscape, Crank and other AMD officials said they believed servers and their applications would be better positioned to take advantage of the Opteron's capabilities at launch, rather than PCs.

The day is approaching when Linux will likely replace IBM's version of Unix, the company's top software executive said, an indication that the upstart operating system's stature is rising within Big Blue.

When National Semiconductor decided to challenge Intel and Advanced Micro Devices in the market for low-end microprocessors in 1997, CEO Brian Halla teased a group of skeptical analysts, saying they probably thought he had been sprinkling testosterone on his corn flakes. Brian Halla predicts a technology transformation in which analog chips displace the zeros and ones at the heart of the binary language used in computing.
