802.11: Understanding the Alphabet Soup

"Wi-Fi's rise through the corporate structure has been meteoric. The technology has quickly progressed from an alternative wireless method to the de facto means to transfer data wirelessly within a LAN. However, before the mass adoption of Wi-Fi in the enterprise occurs, the advantages and disadvantages of 802.11a and the emerging 802.11g must be understood." Read the article at InfoWorld.

Group is Working on a BeOS ‘Sequel’

A handfull of well known --to the BeOS community-- developers have come together to create a new OS, which starts where BeOS left off. Bear in mind that this OS, named Sequel, is not a BeOS clone, but a brand new OS which adds new things in the mix while retains the best features found on BeOS and other OSes. The OS is closed source and it is in early stages: it currently boots off a floppy and has a shell. Editor's note: I am part of the small team, since its first days, a few months ago. I designed part of the UI for this OS, but I am looking forward to get a working GUI system before I dive in and do some "real" work on the UI and usability. Stay tuned for more news about Sequel in the future. UPDATE: Please note that this is NOT "my" project. I merely help out the guys on the UI, and nothing more. UPDATE 2: March 2003: I have resigned of my role on Sequel.

Journaled File System Available for Testing on FreeBSD-Current

The Journaled File System for FreeBSD (JFS4BSD) Project has the goal of porting the JFS Technology from IBM/Linux to FreeBSD. It uses a log-based, byte-level file system that was developed for transaction-oriented, high performance systems. Scalable and robust, its advantage over non-journaled file systems is its quick restart capability: JFS can restore a file system to a consistent state, fsck times go down, and it is easy to fall-back to the last good state of the filesystem in a matter of seconds or minutes. The jfsutils is under a compilable state on FreeBSD. Read more at BSDForums.

GCC Myths and Facts

"Since my good old Pentium 166 days, I've liked to search for the best optimizations possible so programs can take the maximum advantage of hardware/CPU cycles. If I have a nice piece of hardware, why not run it at its full power, using every little feature? Shouldn't we all try to get the best results from the money invested in our machines?"
