Question: Amanda asks, "Where is the underscore key?"
Answer: Good question, Amanda. Often we hear of folks whose email addresses have an underscore in them. Until you find out where that is, it'll be tough for them to get an email from you. The underscore key is the shifted dash or hyphen key. It's located on your keyboard between the 0 and equals sign keys. If you don't hold down the shift key though, you'll get a dash rather than an underscore. Some other keys you may want to take a look at while we're here are the tilde and backquote. These are both on the same key, just to the left of the number one key. The tilde is a little sideways "S" commonly seen above the letter n in Spanish.
Cool Site: HowToLearn.com: It's back-to-school time and with that in mind, this week our cool site is how to learn.com. The site's subtitle is, "How to learn anything fast". Here, you'll find several free resources like a personal learning styles inventory, an Eye-Q reading inventory that helps you determine if you see the page properly, articles about things like the prevalence of autism, free email newsletters, resources for home schooling, memory improvement, teachers, and all kinds of things. You can find information about the learning experts at the site. The site has a bookstore with one title in particular I found interesting that lists natural diet-based remedies for learning disabilities. You'll find sections that are tailored for grade school, college, adult learners, and a section for teachers only. I've mentioned two free inventories, but there's also a phonics inventory, and lots more. It's mostly free stuff, HowToLearn.com.
Cool Gadget: Ceton InfiniTV: Our regular listeners know I'm a TV buff, and I like the idea of using a computer of my own as a DVR so that my programs aren't locked away somewhere else. Before the digital switchover, you could buy a TV tuner card, drop it into a computer, and begin watching and recording TV programs on your computer. Well, after the digital switchover, that has become somewhat more limited. Recording high-def programming is difficult or impossible unless you have the cable company's DVR. But today's gadget is the Ceton InfiniTV 4. It's a PCI-Express add-on card that you can put in your computer and record not one, but up to four programs in high definition simultaneously. Not only that, but you can stream those recordings to other computers in the house and to Xbox 360s as well. Playstation 3s can share these recordings also, but the experience is different. The company is also producing a USB version of the InfiniTV that can be moved around, so that if you don't have a dedicated computer that you use as a DVR, no problem. Both devices retail for $299, and require you to rent a device called a CableCARD from your cable provider.
It's All "Geek" To Me: Analog: This week's term is Analog. It refers to a means of perceiving or storing data in a way that is continuously variable. This is different than digital because digital data relies on periodically storing a value that is continuously changing. A similar situation occurs in music when you transition from one note to another by slurring the note, which corresponds to analog data, versus an immediate switch from one note to the next, which corresponds to digital data. Analog data is actually more accurate than digital.
