I get a lot of questions from people who are trying to decide what specific hardware to put into their computers. More often than not, they are trying to take a very old computer and make it usable again. The problem with very old computers trying to run current operating systems and applications is that it requires almost an entire new computer worth of upgrades to bring it up to speed. On the other hand, I've used several computers now that are a few years old and only need a very simple upgrade to keep them usable for another year or two. The problem is that most people simply don't know when it's worth it to upgrade and when it's time to just replace it all. Fortunately for them, we can answer most of the questions here.
If you have a Pioneer or Premier CD/MP3/Radio in your car and you don't have an auxiliary input already, it's really not too difficult to add it, provided you have a compatible head unit. Models starting with a "P" after the dash such as the Pioneer DEH-P2900 are compatible. The aux input connects through the blue IP-Bus connector on the back of the unit. Pioneer sells an adapter that comes in the form of a little metal converter box but you can get just a cable adapter for much cheaper. I've done this in 2 cars now for about $10 each total and it has worked perfectly each time.
Drupal is a very powerful Content Management System (CMS) that has a well-designed taxonomy module. Taxonomy is the system of categorization and classification of things. In Drupal's taxonomy, you can define multiple vocabularies and the terms in those vocabularies can have multiple sub-terms. This site is set up that way with the high-level terms being general concepts such as "Programming" and "Technology." The one thing I wanted that it did not do out of the box was to show sub-categories as an additional navigation menu when you clicked on a parent category. It's not to hard to implement if you know how. Read on for the code snippets.
If you're fortunate (or unfortunate as the case sometimes is) to be a Qwest DSL user with an M1000 DSL modem and you don't currently have Wi-Fi in your home, there is an excellent upgrade option for around $30 that works very well and is one of the few upgrades I've ever seen that quite literally takes a few seconds to do.
I've had to do this for several of these laptops now so I thought I'd just make a picture tutorial to explain. It's been pretty much the same for all models T60 and greater. What we've been doing is upgrading machines with either 1 or 2GB up to 4GB. The memory is located under the touchpad on the front panel, which is removable via long screws on the bottom. All you need is a philips head precision screwdriver and your new ram, which must be compatible with the machine.
