PearPC Gets Altivec Support

Yesterday, on pearpc.net, it was anounced that PearPC has experimental altivec support. Among other things Altivec theoretically improves OS and application speed due to the ability to handle floating point math operations. The builds can be downloaded here.

Whitepaper: “New Directions in RTOS Kernels”

This technical overview by veteran real-time lecturer David Kalinsky examines a number of directions in which RTOSs continue to change and mature. Two main directions are alternative task scheduling algorithms, and intertask communication via asynchronous direct message passing. In order to keep at a practical level, the focus is on trends and features that can be expected to appear in RTOSs soon.

The OS World’s Best-kept Secret?

ComputerWeekly takes a look at OpenVMS, one of the most stable OSes ever placed in production. Originally known as VMS, it's probably the best designed and most robust general purpose operating system in existence. It's also one of the least-known and appreciated, simply because it works quietly in the background without drama, unlike its noisier and more fussy siblings and offspring.

VAX Users See the Writing on the Wall

The VAX system at Triumph Components has been in use since about 1996, and information systems manager Dan Blackshear couldn't be happier with it. There's just one problem: He's got to scrap it. The system is fast, works well with Windows and "fits into the modern environment very cleanly" at the El Cajon, aerospace parts maker, said Blackshear. "But it's a dinosaur, and eventually it has to go".

PearPC 0.2.0 released

From the PearPC site: "The most important change of this release is certainly that network now also works with Windows as host. Since we now have conditional redraw code, you can take a smaller redraw interval without dramatic speed decrease. With this release, you can switch the screen resolution (i.e. the size of the window) at runtime via the video.x driver. Note that there are some small config file changes, so please update your config file from the shipped ppccfg.example."

ChoX11 and Porting

"Ever seen some Linux application and thought: "the source is available, why can't we have that on RISC OS?" And indeed, because of the efforts that have been made on the GCC port for RISC OS and its C library, Unixlib, this is possible for a large number of Unix applications." Read the article at Drobe.

Virtually Minix: A Tutorial & Intro to Minix on XP via Bochs

This tutorial will walk the reader through setting up Minix 2.0.4 on Windows XP via Bochs 2.1.1. These are the latest versions of Minix, Bochs and Windows XP as of May of 2004. In this era of Linux and Windows domination of the OS scene, it is important to remember that there are alternatives. Hence, this article will also serve as an introduction to one such alternative, Minix, which has a very rich heritage, indeed.

SoftPear’s PowerPC to i386 Recompiler Now Works

The SoftPear Project aims to create compatibility software between the IBM PC and the Apple Macintosh architecture. This is not an emulator for PowerPC Macintosh machines (like "PearPC", "Basilisk" or "UAE"), the project has more similarities to Digital's "FX!32", FreeBSD's "Linux Binary Compatbility" and "WINE" instead. Darwin/x86 or GNU/Linux will run on the PC, and the Mac OS X user interface, its libraries and all applications running on top of it will run on Darwin or GNU/Linux, using SoftPear's compatibility layer. Since today, the PowerPC to i386 recompiler works with many small test programs. The code is in the CVS.
