Paranoid Penguin - DEFCON: One Penguin's Annual Odyssey
In all seriousness, DEFCON already is remarkably good, even incomparable. I can't over emphasize that for my friends and I who attended it, volunteered at it and presented at it, DEFCON 17 was a tremendous success—educational, thought-provoking, relevant, unpredictable, exhilarating at least as often as it was frustrating and, above all, fun.
In the words of Richard Thieme, who at the time wasn't sure whether he was quoting Simple Nomad or Bruce Potter, “For the system to work, it must never grow up and it must make us smile.” Here's to the scene's never growing up. I hope to see you at DEFCON 18!

Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.
