Don't get me wrong, I like Tripwire. It was the first, but it's certainly not the easiest thing to set up. What I dislike about difficult things is not just that I'm lazy (I am), but difficult often means someone, somewhere will misconfigure or otherwise nullify all the good the program should do. This program is fast and easy. Not necessarily better, but different. Requires: Perl and Perl module Digest::MD5.
This small C program will calculate the number of days between any two dates. Granted, this has somewhat limited use, but the author does present an example. It is most useful in scripts. How many days until Christmas? Requires: glibc.
I like this little application. It was designed so that you could connect a (surveillance) camera to your system, run motion, and it would take pictures each time the image changed. You can make a movie, even send an e-mail. Yep, great for security. But I (ab)use it differently. I connect my video camera after taking a home movie, let motion grab frames every second. Then I load all the images into xv and delete what I don't want and rename what I do want. Much faster and easier than doing it manually—a lot of options. This is a keeper. Requires: libjpeg, libmysqlclient, libz, libcrypt, libnsl, libm, glibc.
Until next month.
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.
