Commandlinemac.blogspot.com Website Review

since late 2011, i've found myself doing a lot more linux administration than mac. in light of that, i am launching a new linux across something interesting in the mac world, but i expect the other blog to be much more active this year. satellite+dsl. it was an inconvenient process to say the least. when it was done, i needed to connect the satellite dvr to the wireless dsl the dvr had a usb wireless adapter, but because of the location of router, the signal was not quite strong enough to make the connection work. i had a spare airport express and my first thought was to use it to extend the dsl router network. before doing any research, i made manual changes to the airport express that rendered it a brick. doh! finally did the research and found that the plain express can't be used to extend a 2wire wireless router. the next strategy was to set up a separate wireless network and plug the airport express into one of the wired ports on the router. the airport express provided a stronger signal that the 2wire and allowed me to connect the dvr to the internet. the only modification i had to make from a basic configuration was to turn off network address translation (nat) on the airport express to avoid a double nat situation since the 2wire also provided nat. the airport express actually detected the problem and made the suggestion when i connected to it with the airport utility. apple really has some very nicely thought out software in their hardware. i was working on a project today and needed to make some changes to the way an array on objects was sorted before being displayed on the screen. the main reason i even bothered to post this is to heap a little more praise on ruby for working the way i expected it to work. here was my object (not tied to a database, just created for convenience): i sorted them by concatenating the fields together and making the right comparisons. this only works because the first two fields, rank and shift, cannot be empty. otherwise, a simple concatenation would create undesired results.
