"As we are now officially in the holiday season and done with SC10, I can only think of one thing. Next year?s SC11 in Seattle. Just kidding. I?m still digesting SC10 and still surprised we are heading back to Seattle next year. My understanding is that SC tries to rotate east coast then west coast every other year. Let?s see, SC10-New Orleans, SC09-Portland, SC08-Austin, SC07-Reno, SC06-Tampa, SC05-Seattle. I see a little bias for the left side of the Mississippi river. Except for Tampa, the last time it was even near the east coast and the northeast corridor was SC04 in Pittsburgh. And, now we loop back to Seattle next year. I?m not even going to guess who Microsoft will foist on us for the keynote.

"Back to New Orleans. On Monday of SC10, before all the hoopla began, I managed to have lunch with James Reinders of Intel. James title is ?Director, Evangelist, Intel Software.? He also has written quite a lot about parallel computing and blogs about many of the major software advances coming out of Intel. Each year I check in to see what is new and interesting."

Tips for Securely Using Temporary Files in Linux Scripts

"Over the years, I've written hundreds, if not thousands, of shell scripts. With the ease at which you can redirect input and output within a shell script, many sysadmins store data in temporary files for processing purposes. In some situations scripts become essential to the day-to-day operations of a system and as such, may end up running on a regular basis via crontab ? never to be looked at again.

"Unfortunately, some sysadmins who write scripts might store sensitive data in temporary files, don't restrict access to temporary files, and might forget to remove them from the system when they are no longer needed. In many cases, they use them when it isn't even necessary. The beauty of Linux and UNIX is that there are hundreds of ways to accomplish the same task. I will keep my Bash examples simple so you can focus on grasping the general concepts."
