Summer

Summer has come! And more importantly, my vacation has begun, 5 weeks of nothing! Well, almost nothing. I’m taking my sisters and my pregnant girlfriend to Bornholm and a small trip to Germany… Should be fun ๐Ÿ™‚

“Three things can happen to light when it hits a material,” says Boston College Physicist Willie J. Padilla. “It can be reflected, as in a mirror. It can be transmitted, as with window glass. Or it can be absorbed and turned into heat. This metamaterial has been engineered to ensure that all light is neither reflected nor transmitted, but is turned completely into heat and absorbed. It shows we can design a metamaterial so that at a specific frequency it can absorb all of the photons that fall onto its surface.”

Have been a bit busy, to busy to keep this place updated even…

I’ve been trying to get a calendar solution up and running. I started out with phpIcalendar and experimented a bit with webdav for apache. I wanted a solution that gave me the the possibility to have my calendar-software (in this case KOrganizer) running on different machines but using the same iCal-file. After I got webdav running I realized that it would be much simpler just to use the already running ssh-server. I used the KDE fish: protocol to connect KOrganizer to my ssh-server and it works like a charm!
