Google Reader => Netvibes

Because google will stop with Google Reader I switched to Netvibes. In reader mode it is almost as good as Google Reader.

Swedish house on the Moon

manhus2There is a man from Sweden who wants to build a house on the moon. This entrepreneur, Mikael Genberg, started to build a one room hotel high up in a tree in a park. That idea got worldwide press coverage. Because this was a big success he started building a floating one room hotel (glass cellar) so you sleep between fish. These hotels are now all over the world.

In march 2013 a Swedish consortium will put a lunar module in a custom Dnjepr-missile. In the lunar module is a surprise packet the size twice a shoebox. This kit will transforms itself, once on the moon, in a nice swedish house. Six by two meters, with a lovely sloping roof. By tradition cottages in Sweden are built of wood but the moon cottage will be constructed of a very light weight material and be both collapsible and inflatable. It will last about 100 million years.

You can Shorten goo.gl links with goo.gl. I don’t understand why but now you can create links like http://goo.gl/LoeN┬áthat don’t go anywhere. This because your browser stops redirecting after some x redirects. This is what IE 8 does:
