Axel, Bruno and the rest of the company in the OpenBFS team, have completed the development of OpenBFS, the open source equivelant of Be's popular 64-bit journaling file system. OpenBFS currently runs on BeOS 5, awaiting the further evolution of the OpenBeOS/NewOS kernel in order to start a back port. The team reports that while the filesystem clone is not very well tested yet, it is already seems pretty stable and it beats in performance the original BFS.

"Disgruntled Solaris users are pushing Sun Microsystems Inc. to decide on the fate of the operating environment on Intel Corp. processors. Sun officials in Palo Alto, Calif., have been going back and forth with the Solaris Intel user base since January, when the company said Version 9 for the x86 architecture was being "deferred" in favor of projects that were more profitable. Now the process seems stuck, and users are getting restless, according to sources familiar with the negotiations between the user community and Anil Gadre, Sun's vice president of Solaris software."

One of the early GUI operating systems for the PC, that is still being developed today, is GEM, an operating system that was originally created by Digital Research in the early 1980s. GEM was described as providing a Mac like GUI for the PC – long before Microsoft Windows 3.1 or 95. Today GEM continues to be developed as FreeGEM and old and new versions of the GEM OS and GEM applications can be downloaded for free (see links below). The history of Digital Research and GEM is quite interesting, as GEM had the potential to become the "Windows" (or Mac) of the PC world.

"Day after day since 1984, teams of programmers, linguists, theologians, mathematicians and philosophers have plugged away at a $60 million project they hope will transform human existence: teaching a computer common sense. They have been feeding a database named Cyc 1.4 million truths and generalities about daily life so it can automatically make assumptions humans make: Creatures that die stay dead. Dogs have spines. Scaling a cliff requires intense physical effort." Read the interesting article over at CNN.

The software-only company Amiga Inc. has published a marketing document outlining how it will sell AmigaOS4, which will run on third party POP-based (PowerPC Open Platform) hardware. Now, however, the open hardware seems to become artificially closed.

The OpenBSD project is currently having what is called a "Hackathon", that is, as many coders as possible, get together for a little more than a week and hack, drink beer, hang around etc. This year, it all happens in Theo deRaadt's hometown, in Calgary, Canada. The slogan of this hackathon is: "Shut up and hack!" Check out pictures of the event, and see the (always growing) number of CVS commits here. The event is terminating late next week.

Linux-sxs.org features an informative article on how to compile Mozilla from source. Especially if you have switched to GCC 3.1, you can build some really optimized binaries for your Mozilla, as GCC 3.1 does better optimization in general, plus it supports special optimizations for Pentium4 or AthlonXP.

Last year, Red Hat CEO Matthew Szulik thought Sun Microsystems' open source-based alternative to Microsoft's widely used Office software would encourage broader use of the Linux operating system on desktops and perhaps loosen the iron grip of Windows. But Szulik abandoned those hopes when Sun started charging for its StarOffice product and changed its way of dealing with the original equipment manufacturers, such as Red Hat, which can bundle it with their own offerings. Szulik accused Sun of adopting the domineering methods of mutual enemy Microsoft.
