    Will Any Old GBIC Work?

    You have two switches and you’re thinking that you’ll use the GBIC from your old switch on you new switch.  You have an Xsan and you have a bunch of GBICs laying around and you want to know if they’ll work.  You have a fiber run and you want to use a transceiver.  Etc. This is a tricky question.  The GBICs should all work.  The general rule of thumb though is, if you use the same GBIC on both ends then you shouldn’t have a problem.  But, it’s also important that (for whatever reason) some manufacturers do require certain GBICs either to actually interface or just to support an interface.

    Mac OS X: Alex.SpeechVoice

    Have you noticed how big Mac OS X has gotten?  Wonder why?  Well, for the most part Apple does a good job with compression and file management.  But things like iDVD, Garage Band, etc are taking their toll.  Then there are printer drivers and fonts.  And then there is this gem: Alex.SpeechVoice.  In the /System/Library/Speech/Voices/Alex.SpeechVoice/Contents/Resources is a file called PCMWave.  This file is 692MB.  If you don’t plan on using the Alex voice then trash it to reduce the size of your image considerably.

    Mac OS X: Disk Inventory X

    For those that would like to see a graphical inventory of the files on your system there is Disk Inventory X.  Cool little app, although you could do something similar using the command line.  But this is a nice little GUI app that shows disk usage statistics in a tree map.   http://www.derlien.com/
