Windows XP SP3: Problems, Performance Gains

Windows XP SP3, the final service pack for Windows XP, was released to manufacturing a few weeks ago, and popped up on Windows Update about a week later. Even though the service pack is rather light on actual new features, it still caused a few problems for some users. Despite these problems, some benchmarks show that while SP3 delivers better performance compared to XP SP2, Microsoft seems to have solved many performance issues with Vista, turning the company's latest OS offering into the better choice for gaming - according to ExtremeTech.

A History of the Amiga, Part 7: Game on!

Ars Technica's Jeremy Reimer has published the 7th instalment in their series on the history of the Amiga platform. Part 7 deals solely with gaming on the Amiga, detailing various classic Amiga games that in one way or the other pushed the envelope. "The Amiga started out its life as a dedicated games machine, and even though it grew into a full computer very quickly, it never lost its gaming side. The machine's 4096-color palette, stereo sampled sound, and graphics acceleration chips made it a perfect gaming platform, and it didn't take long for game companies to start taking advantage of this power."

Microsoft To Discount Windows XP for ULPCs

Last week, we reported on a peculiar price difference in Australia between the Linux and Windows versions of the Asus Eee PC 900, the new model in the Eee line. The Windows model was 50 USD cheaper than the Linux model - the Linux model did have a bigger hard drive, but interestingly, the version with the smaller hard drive was not available as a Linux machine. This gave rise to speculation that Microsoft had been putting pressure on Asus to favour Windows XP over Linux. It appears Microsoft's assault in this segment of the market goes deeper than just Asus and the Eee alone.

Anatomy of Security-Enhanced Linux (SELinux)

Linux has been described as one of the most secure operating systems available, but the National Security Agency (NSA) has taken Linux to the next level with the introduction of Security-Enhanced Linux (SELinux). SELinux takes the existing GNU/Linux operating system and extends it with kernel and user-space modifications to make it bullet-proof. If you're running a 2.6 kernel today, you might be surprised to know that you're using SELinux right now! This article explores the ideas behind SELinux and how it's implemented.

The Popup Scrollbar Concept

As you may remember from our series on common usability terms, I have a lot of interest in graphical user interface concepts. In addition, I applaud anyone trying to improve existing concepts, people that try to think beyond set conventions to come up with an improved version of that concept, or a new concept altogether. Thorsten Wilms took on the well-established concept of the scrollbar, and came up with a few interesting tweaks.

Perceptive Pixel’s ‘Magic Wall’ Finds New Niche

Multitouch has more or less turned into a buzzword these days - sometimes, its implementation makes sense and comes out as pretty useful (see the iPhone and Microsoft's Surface), however, other implementations turn out be debatable. There is another implementation out there, one that received a lot less attention from the press than the aforementioned cases: Jeff Han's Perceptive Pixel.

Memristors Discussed on Talk of the Nation

Today's NPR Talk of the Nation Science Friday radio program discussed the recent Memristor advances for the non-Electrical Engineer: "The possibility of such a circuit element, known as the "memristor," was first described in 1971, but no one was able to find a device with the properties of that missing element. Now, a group of scientists at HP Labs has found that in nanoscale materials, the "memristance" property becomes easier to see. The finding could lead to lower power, instant-on computers, as well as novel types of circuitry. HP Senior Fellow Stanley Williams, one of the discoverers of the modern memristor, talks about the find and its potential applications." The 13 minute program is available online

Syllable, SkyOS, ReactOS Move Forward

There are quite a few operating systems which have moved beyond the simple hobby operating system stage, onto a more lasting plane of existence. AROS, ReactOS, SkyOS, Syllable, Haiku; they're no longer basement products, coded by a single programer - they are now projects in which a lot of people have invested time, and possibly money too. They won't go away any time soon. The last few days have seen news on three of these systems: ReactOS, SkyOS, and Syllable.

Windows XP Eee PC Cheaper than Linux Variant

As we all know, the Eee PC, running a modified Xandros, has been a major hit for Asus, and because of that, also a major hit for Linux. The device proved that a computer with a pre-installed Linux distribution can still be s successful machine, and many hoped that this would push Asus and other vendors to produce more computers with Linux pre-installed. This hope could be in vain after all if the new Windows XP-based Eee PC has anything to do with it.

Qt 4.4 Released

Yesterday, Trolltech released the final version of Qt 4.4, their graphical toolkit which forms the base for, among a lot of other things, the KDE project. It still features the dual-license model (of course), so proprietary developers can license Qt, while open source developers can get a GPLd version (both GPL 2 as well as 3). Read on for a quick overview of the new features, as well as some findings by Ars Technica.
