Virtual credit card number

My Citibank MasterCard allows me to generate a virtual credit card number, pretty simply, using a fairly ugly web interface. But a few clicks and you get a picture of a credit card, including numbers, dates and CVC. The magic is that this credit card can be used only once so if it’s stolen you don’t run a risk. Pretty cool. I just used it to pay for some software online and it worked like a charm. Simple and useful!

“This is the Discover card Fraud department. Call 1-800-555-1212 – IMMEDIATELY

Sounds ominous, right? So I call them up, and I hear a serious voice telling me to please hold on, then I hear the official sounding “you are being recorded” beep beep beep. Then the voice comes on the phone and says, “Thanks for calling Discover Card. Please give me your Discover Card number.” What would you do? I am worried about fraud on my card, right? But do I know who I am actually talking to?

Why should do online check-in when flying?

This, from American Airlines: > “Your trip is eligible for check-in now. Save time at the airport and check-in on AA.com® any time from now up to one hour prior to your departure. To use our new instant check-in feature, simply click the button below and print your boarding pass. Save this email and use your personal check-in button for quick and easy check-in for your return flight.” Anyone have any idea what possible benefit I get for checking in online? I don’t think any of these - Save Time? How? I still have to go show my Id before getting my boarding pass don’t I? - Checked bags? Still have to go to the counter as usual, don’t I? Checking in online seems cool, but why???

Asymmetrical conflict in the blogosphere

I met with a potential client the other day who was on red alert because there were a lot of nasty things being said about them on blogs, comments and forums. And I thought of the concept of asymmetrical conflict as we have learned about it in recent years. Even without knowing whether the criti...

Check out Arduino, a totally cool tiny embedded computer suitable for creating smart things – art, robotics, sensors and controllers. You program it on your laptop, and download the program to the device. I tried it, it was pretty easy. Had to touch wires and stuff though 🙂...

Amusing: French words missing in English

“No language is perfect, and English is no exception. There are always words or expressions that cannot be rendered from one language to another. English supposedly has the largest vocabulary of any languages in the world (7x more words than French !), and well-educated people typically know less th...
