Every now and then it’s a good idea to check your UPS batteries, right? Sure, we all know that. But who really does it? In well run environments UPSes are monitored, internally and/or externally but in a small machine room with only a couple racks, the individual UPS systems may not be monitored. These machine rooms (closets?) might also not be frequented by people very often or may not even get a visit, ever unless something goes wrong.

l2c.pl – Lines to Columns
Here is a little perl script I wrote some time back for converting a text file’s contents from lines to columns.
I’d like to present this script and then psuedo-challenge other visitors of this site to write a more efficient algorithm in the language of their choice. Unfortunately, any way (that I know of) for measuring the efficiency of two or more algorithms across different languages is going to be skewed due to differences in efficiency of compilers, interpreters and what not.
OpenGear CM4116 Review
I recently started paying more attention to the OpenGear CM4116 remote console server that was installed at my work before I arrived.
