"Dennis Ritchie: The single thing that I'm happiest about is that the notion of making the Unix system portable was mostly mine. C was already implemented on several quite different machines and OSs, Unix was already being distributed on the PDP-11, but the portability of the whole system was new."

|Grid Computing Oracle Style|
|Linux Planet tells us about
Grid Computing Oracle style.
"Benny Souder is Vice President of Oracle Distributed Database Development. In a recent interview, he talked about Oracle's 9i product, the Linux-based grid platform, and ways that the combination benefit the customers.
"Oracle is focused on all aspects of data management. Specifically how to make data available and how Oracle 9i can help clients," Souder said.
"The main idea behind a grid is that it is thought of as a utility. Much like the electrical utility grid."

|On Lamp talks about
one time passwords.
"There is another authentication system known as One Time Passwords
(OTP). As the name suggests, you can only use a password once; you aren't
allowed to reuse it. An OTP system ensures that a discovered password is
useless to the person who discovers it. This can provide a bit more
security in a world that contains password crackers, packet sniffers, and

|Linux at the National Weather Service|
|Newsforge talks about
Linux at the National Weather Service.
"So how does Linux compare in performance to current NWS systems? According to Kirkwood, their current HP-UX systems can take up to eight minutes of start-up time to load their software should the system go down, while Linux on the Intel platform takes under a minute. In addition, the switch has helped increase data processing speed. The performance that we measure with our benchmark has increased by over 100% since we completed phase one of our Linux migration," happily boasts Piercy."

|Cleaning Core Dumps Made Easy|
|Linux Orbit Professional takes a look at
"So what are core dump files for? Used mainly as an aid for software developers to debug problems, a core dump is a snapshot of the information in your system RAM at the moment a program crashes. Most users aren't developers however, so although they serve a purpose, they can be a problem."

Securing Systems with chroot.
"When a process requests to chroot to a given directory, any future system calls issued by the process will see that directory as the filesystem root. It becomes impossible to access files and binaries outside the tree rooted on the new root directory. This environment is known as a chroot jail."
