Linux Journal Contents #189, January 2010
You say potato, I say potahto, you say ham, I say amateur... you see where I'm going with this? Ok, maybe not, Amateur Radio, that's where and that's what this month's issue focus is. What you might ask is the connection between Amateur Radio and Linux? Well Linux may be the only O/S out there with an AX.25 packet radio protocol driver, and it's had it since forever. So blow the dust off your license and start reading. If Ham's not your favorite food, don't despair there are plenty of other articles in this month's issue including, but not limited to, Firewall Builder, Cucumber, Vimperator, port knocking with knockd, building appliances with Linux and Xen, and using Twitter from the command line.

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.
