Why I decided to keep the name of this blog - how to remember Pi

Thank you  for your mails and the comment ;-)
I admit that I thought of changing to tumblr. There are no more rememberable subdomains left at blogspot. But  then I decided to keep the name as it is. Why?
My thought was the following:

1. When I have a genius idea I can switch. Then it will be a full domain.
2. People come to my blog because they search in google, click a link or simply because they follow my tweets.
3. People come again because they follow my tweets, have a bookmark or simply remember Pi.

You want know how to remember the first few digits of Pi?

The Greek letter pi (source: Wikipedia)

3,1415 is sufficient for most calculations Pi, starts with three (rhyme) and continues with some addititions:

3 + 1 = 4 ...+ 1 = 5 and now you can remember my blog stst31415.blogspot.com

Do you want one digit more? Just add up the digits. The last sum which is below ten is the next digit 

3+1+4+1 = 9 the next one would be to "start again": 3

Try this at home.

How to create a QR code business card

If you own a smart phone - or an even smarter phone you probably already know what an QR code is. If you don't know I a sure you will have seen this somewhere on the web or in a magazine.

A QR code is a two-dimensional barcode. A big part of it consists of error correcting code and it somehow looks funny. I was looking for a possibility to share my contact coordinates or even calendar entries for smart-phones when I stumled across http://zxing.appspot.com/generator/

With that webpage you can create these QR codes for your business card, for coordinates and for calendar events. When you try the calendar event, test the QR code before you use it. Daylight savings time is a real *****. When I tested it on my HTC Desire with Barcode Scanner I experienced a strange bug. Every calendar event I created lasted only for 1 hour. Even when it was supposed to be longer.

Anyone with Blackberry or Iphone experiencing the same behaviour?

How to get readable texts in your browser

Yes. There it is: The problem which is as old as the internet: I cannot read the text because of all the clutter, I cannot print the page, because of all the clutter... I think, there is no need for me to continue?
Well. The solution is Readability. Another bookmarklet in your browser which simply does what it says: It makes the page readable. On the web. The perfect possibility to leave out the noise and get to the point: reading.
Read for yourself why they did it and try it. I am sure you will love it.
