The Difference Between Flash Memory and a Hard Drive

One of my favorite computer help sites, Of Zen and Computing, published a great article about the difference between flash memory and a hard drive. I really should have thought of this myself, as I often have to explain the difference.

The short answer...

Both are used for long term storage. A hard drive uses spinning magnetic disks. Flash memory is just a chip, it has no moving parts. No moving parts means it is less likely to fail. However, you can't just replace your hard drive with flash memory, yet.

Nike + iPod

For Father's Day I got a new pair of running shoes and the Nike + iPod Sports Kit. I have used it for about 3 weeks now and I absolutely love it.

In case you don't what I am talking about, the Sports Kit is a accelerometer that is attached to your shoe. A receiver is attached to your iPod Nano which is allows it to measure and record distance and pace of your run or walk. Personally, I don't care for running, but I do like to walk.

The coolest part is that your run data is synced to a Nike website. The website will track all of your runs and makes note of your quickest times. The part of the website that I thought I would use the least, has turned out to be my favorite. The challenges. Anyone can make a challenge and invite others to complete. You can set all sorts of requirements for the challenge. For example, I am competing in the Terrific Turtle Challenge. I am competing to run/walk the most miles over 21 days. The only rule is that you must be slow, your pace must be over 10 minutes per mile. I am currently in 10th place.

The Sports Kit runs about $30, not bad if you already have a Nano. You are supposed to use Nike+ shoes, but I have read that you can attach to any shoe and get good results.
