Here is a list of all shortcuts using the Windows logo key on your keyboard ( ), courtesy of Tech Republic. They did a pretty good job with this by listing all of them, not just the common ones. Note that some of them work only in Windows 7.

It’s eight weeks since the last major Firefox release, so you know what that means: time for another one. Mozilla just released version 6, which includes…..uh…..some visual enhancements. This is what they call a full version? I’d call it an x.01 version increment.

What’s really annoying is that Mozilla is considering dispensing with version numbers altogether, and just telling you if you have the latest release or not. That’s bad enough for users who might be having technical problems, but even worse for web developers who want to make sure their sites work properly in all browser versions.

How often does this happen — you’re out for dinner with friends, and when you get the check, several people don’t have cash and want to pay with plastic? Or maybe you want to split the cost with someone of a birthday gift. Or you have a small business that takes you on the road, or a side business selling stuff on Craig’s List, and people want to pay with credit or debit cards.

If you have a Droid, iPhone or iPad, a company called Square can make your life a lot easier. They provide you with a small, square card reader that connects to your mobile device. You can then accept credit card payments. And there’s none of the usual hassle of a processor doing an intrusive background check. Just fill out the form on www.SquareUp.com, and they’ll send it to you. Even babysitters are using this service.

For me, the most surprising part is the cost. They charge you 2.75% for each transaction, and that’s it. No monthly charges or anything else. That’s what any business would expect to pay. Compare that with some well-known, online credit card processors that will take up to 10% of your receipts.
