Hi Dave this is my first time writing to you. I am going to be letting one of my employee's go and I'm not sure how long I can wait to give him his last check. I want to let him go tomorrow the 2nd. Paychecks won't come until Monday the 5th. Is that too long?

Ever wonder where your kids go during the day? Or perhaps you're curious how many miles you travel, point to point, in a typical week? Heck, maybe you're the suspicious type and want to know where your spouse drives the car while you're working?

All of these questions can now be answered by devices called GPS tracking systems that combine the geolocation capabilities of a GPS with a rudimentary recording system and a simple computer interface, typically all packaged as a chunky USB memory stick.

The Telespial Systems' Trackstick II is one of the more interesting GPS tracking systems on the market and I was pleased to get one from the company for review. It's clunky, but performs as advertised, offering a wealth of interesting data and answers to all of the questions I posed above.

I just got a new iMac, after years of working on Windows XP systems, and a pal was telling me that one of the coolest features of Mac OS X is that you can redirect any printout and turn anything into a PDF. That's awesome because I constantly send Web pages to clients and PDFs will be a lot more reliable than the HTML source. Can you show me how to do this?

I've read all your other Sony PSP articles fanatically, but I haven't found anything you've written about how to access the Skype service from the PSP. Can you show me how to connect with my Skype friends through my Sony PSP, please?

I'm new to Google AdSense my website is a social networking. My page views of a single day is about 10000, but my Google AdSense impression shows only 4000-5000 impressions. Could you tell me why?

It's New Years eve and my friends and I are debating: how many time zones are there on Earth? I say that there can't be more than 24 time zones, but my buddy says there are more. Seems like that'd define how many times New Year is celebrated each year.

I got a great gift from my folks, an Apple iTunes gift card. Nice. And I have an iPod. What I don't have is any clue how to redeem an iTunes gift card. Help!

One of the reasons I bought the Sony PSP was so I could listen to some of the radio broadcasts available via the Internet from Switzerland, where I grew up. Can you explain how I can do that?

I've written about this before, about how to connect your Sony PSP to the Internet, but I think it's worth writing about again, detailing one of the most common questions people have with their Sony PSPs: how to connect them to the Internet.

Hi, I went on craigslist.com and saw that they were giving away a pool table. I emailed the guy and asked for some pictures and he sent me an email back saying that he had posted them on his blog and put the web address in there. I clicked on the address and it said that I had to install something to see the pictures, I did not, but I really wanted to see the pictures. I clicked it again but this time it took me to ask.com. Could he have just put the wrong web address or was he trying to give me a virus? Thank you

I just bought a slick ASUS Eee PC netbook, model 1000HA, and want to configure it to work with both Microsoft Windows XP, which is already installed, and Ubuntu or some other flavor of Linux. How can I do that without having to reinstall WinXP?

I just bought my son a new Sony Playstation Portable and every time he starts it up to play a game we see the error message "No Memory Stick Duo found. A Memory Stick Duo is needed to save game data". What does it mean and why wasn't it included with our PSP?

I don't know what my daughter did, but suddenly the "My Computer" icon isn't showing up on my Windows XP computer and I don't know how to make it reappear! Without it, I can't find my files, which is a huge problem. Help!

Hi Dave and Merry Christmas! I just got a new Nintendo Wii and am so, so psyched! Problem is, my folks gave me a coupon for a free game rather than giving me a couple of games. Which means I need to figure out what are the best video games for the Nintendo Wii. Can you help?

Is Santa Claus real, or just something us grownups invented to keep kids guessing about the presents they receive on Christmas morning? It's a question that I wrote about on my blog a few years ago (see Is Santa Claus Real?) and since then have been delighted to receive literally hundreds of comments, almost all from children, talking about their own beliefs and their "proof" that Santa is or isn't real.

I thought that in the spirit of Christmas it would be fun to just share some of the more amusing and poignant comments that have been added over the years.
