Journal File Systems in Linux

"First of all, there is no a clear winner, XFS is better in some aspects or cases, ReiserFS in others, and both are better than Ext2 in the sense that they are comparable in performance (again, sometimes faster, sometimes slightly slower) but they a journaling file systems, and you already know what are their advantages... And perhaps the most important moral, is that Linux buffer/cache is really impressive and affected, positively, all the figures of my compilations, copies and random reads and writes. So, I would say, buy memory and go journaled ASAP..." Read the rest of the 8-pages long article.

A .NET Primer for Mac Users

"I wrote this after reading a confusing rant called 'Microsoft's .NET & The Advent Of (More) Nuisance Technology' on a site called MacObserver. The mispresentation of .NET in that story concerned me — not because it was negative, but because the author confused .NET with Microsoft's forthcoming web services (then called Hailstorm, now called '.NET My Services'). This is like critisizing MacOSX because you don't like iPhoto." Read the rest of the easy-to-follow presentation of .NET.

Intel Designs a 64bit x86 CPU?

Rumors abound that Intel is designing 64bit extensions to it's Pentium line, in case Itanium turns out to be a flop: "Intel's decision to back the novel Itanium architecture had upset a small group of Intel engineers in Oregon, who preferred to build on the x86 legacy. When AMD released the specifications of its upcoming 64-bit chips in the summer of 2000, these ``cowboy'' engineers decided that Intel needed to match its rival. They began developing their own 64-bit extensions to the Pentium line, making sure the code was compatible with AMD's design." Update: MercuryCenter has an article about this too.

Is There Life Outside Microsoft Office?

"There are alternatives to the ubiquitous applications suite, but in most cases, they're not worth the trouble. Do you need to have Microsoft Office on your PC? Because Word, Excel, and PowerPoint have become the de facto standards for word processing, spreadsheets, and presentations, it's tough to do any sort of business on a computer without being able to read and edit files in those formats. But if you're willing to make some compromises, there are alternatives." Read the rest of the editorial at BusinessWeek. In a related note, Gobe released a new demo of gobeProductive3.

Torvalds Looks Ahead

"As the Linux community prepares to congregate next week in New York for the LinuxWorld Conference and Expo, the center of attention, as always, will be Linux creator Linus Torvalds. A little more than a year ago Torvalds released the 2.4 kernel and has spent much of the year working on numerous 2.4.x versions to further stabilize and strengthen Linux. After handing the 2.4 kernel over to Marcelo Tosatti to maintain late last year, he turned his attention to the 2.5 development tree. Torvalds took time out to exchange e-mail with eWEEK Senior Editor Peter Galli about his work on and vision for 2.5." Read the interesting Q&A at eWeek.

Some Historical Unices Now Available

Caldera is releasing the source of some of the historical Unices it inherited through its acquisitions, including 16 bit UNIX Versions 1, 2, 3, 4, 5, 6, 7 for the PDP-11 and 32-bit 32V UNIX. However, the more "interesting" UNIX versions, UNIX System III and UNIX System V (and their descendants) are purposely omitted (probably to prevent competition with UNIXWare and OpenServer, or to harvest the relevant technologies from them that Caldera wants to keep in its pocket.) A PDF of the license is available for viewing. The archives of the various historical UNIX ports is here.

Book Review: Linux System Administration – A User’s Guide

So, you are a Windows user or a not so Unix-oriented person who wants to master the art of administration? Then "Linux System Administration - A User's Guide" book may be just right for you. And if you are already an admin working somewhere, we are sure you will find in this book something you did not know yet. Read more to see what is included in this comprehensive guide to Linux administration.

More Information on the BeOS Dano Version

The BeOS version 5.1d0 seems to have been extensively leaked on the web the last few days (please respect the OSNews policy and do not post direct download URLs of the illegal beta on our forums). Dianne Hackborn, ex-Be engineer, now at PalmSource, gives more information on what is included in this version of BeOS. There is hardware OpenGL (update: GL is 'broken' on Dano), new networking stack, window decors, XML kit, new USB stack, brand new Printing Kit (and lots of printer drivers for it), new font engine, column list view, tooltip support, updated Media Kit, Interface Kit and app_server, and more. And of course, brand new drivers, like support for the Adaptec U160 SCSI controllers, better SB128 support etc. Reportedly, this BeOS version has some issues with many existing BeOS applications, mostly because of the changes in the app_server. The only peculliar thing is that, as far as we know, Palm's legal department did not take any action against the owners of the servers that carry the leaked beta.

Linux: O(1) Scheduler Benchmarks

"Partha Narayanan, from IBM, recently posted some benchmark perfomance results for Ingo's O(1) Scheduler. The tests were run on an 8-way 700Mhz Pentium III, with several comparisons. The end result is around an 18% improvement with a single CPU, around a 45% improvement with 4 CPUs, and around a 187% improvement with 8 CPUs. Pretty impressive!"

Upgrading to .NET – Article at MSDN

"Get the core information you need to get the most out of the .NET Framework and Visual Studio .NET, including tips and tricks on the new data access system (ADO.NET) and Web application system (ASP.NET). The articles focus particularly on the Visual Basic developer, but apply across all languages." Read the interesting article at MSDN, among four more .NET-related articles.

Twenty Years of TRON

The surprising truth about Disney's 1982 computer-game sci-fi film, Tron, is that it's still visually impressive (though technologically quaint by later high-definition standards) and a lot of fun. Tron was the first movie to use CGI (computer generated graphics & special effects) incorporated into the normal film. To celebrate 20 years of the breakthrough in both Hollywood's and computer's standards, Disney has released the "Tron - 20th Anniversary Collector's Edition" DVD with 5 hours of extra material on the making of the classic movie.

QNX RtP 6.2 — World Preview

QNX is an operating system that all of us have used, but few of us realize it when we do. The OS was created in the early 1980's by QNX Software Systems, a Canadian company, but the version we are previewing today (unreleased yet, version 6.2), based on the Neutrino kernel, was pretty much (re)written from scratch some years ago. QNX is used everywhere, from VCRs, to DVDs, to medical machinery and even satellites and space shuttles. Many of you maybe even have tried the old demodisk, a demo of the QNX4 RTOS, plus the previous version of the Photon GUI, fitting in a single 1.44 floppy. The desktop-enhanced version of QNX RtP (free for non-commercial use) runs on almost all modern x86 CPUs, and if we judge from the following screenshots, it looks pretty good for an embedded system OS.

On Hammer Processors and Their Performance

Two slides of an AMD presentation were leaked to a Czech web site and they show the SPECInt 2000 CPU benchmark performance results of the upcoming AMD 64-bit CPU, Hammer. In the two charts you will see the Hammer scoring best performance among Intel, HP, IBM, Alpha and other CPUs. The Hammer CPU is expected to be released at the end of 2002, after slipping the original release date of March 2002.

The Future of Apple – A Special Report at BusinessWeek

BusinessWeek features an extensive set of articles, editorials & interviews with key Apple people regarding the future of Apple and MacOSX. A very good read overall. In the meantime, MacUserUK and MacMinute revealed that Tuesday 22nd of January is the most likely day that Apple will announce three new, top of the line, PowerMacs: 800, 933 and dual 1 Ghz, with all models "shipping immediately." Pricing and additional specifications are unclear, although sources suggest that Apple may make the SuperDrive standard on all systems.
