iPhone iPod Touch: Multiple Apps Open at the Same Time

When I first started researching this it appeared the iPhone and iPod Touch might not be able to run multiple processes, but I was starting to wonder how in the world could that be. This does not appear to be the case though and instead it appears that Apple has set forth some fairly strict guidelines to keep developers from developing applications that eat up tons of RAM by allowing them to run wild with background processes. The iPhone has 128MB of RAM thus it could be chopped down to nothing very quickly by multiple applications running at the same time.

Easy Management of Nagios Configuration Files with Web Based GUI Monarch

Nagios is a great solution for monitoring hosts, networks, and services on one or more networks. Nagios will monitor as many services as needed per device and then will send an alarm if one or more services has an issue. By default Nagios monitors a bunch of services such as ICMP, HTTP, etc. but can easily be expanded by the use of plugins and other community based open source development projects where code is developed for a specific need and then shared with the development community.

Technology Errors

Failed during this command: RGARCIA/perl-5.10.0.tar.gz : make NO isa perl

First let me say I am not very familiar with Perl or with CPAN so this is to hopefully help out anyone else in my shoes. I received the below type of error during various attempts at installing items from the CPAN shell. I will provide a couple examples of the errors as well as how I figured out that in reality I already had the latest version installed for my version of Perl, which is Perl 5.8.8, and the error was really saying there is a new version but Perl 5.10.0 is required.
