Earth3D visualizes the earth in realtime in a 3D view. One can rotate and zoom the view and fly around. Additional data layers can be added to the view, e.g. country flags and names. It uses data from NASA, USGS, the CIA, and the city of Osnabrück. The data is loaded on demand over the Internet.
Re: ReiserFS Availabilty - production systems
I think reiserfs has still some errors. I have here a reproduceable problem: When I convert a rpm package of the commercial software sniff++ by using alien to a debian package the computer slows down more and more. I managed to shutdown the system because working was not possible any more and it could not unmount the filesystem. After a reboot I had some files in my /tmp directory I could not delete any more (I was root and had all rights, it was definitly a file system problem). I tried this on my notebook and my desktop pc and had both times these problems and could not convert this package. This was both on reiserfs.
Then I changed my filesystem to XFS and tried it again (or on my desktop-pc tried to convert it on a partition with XFS) and I had no problems!
So there IS an error in reiserfs.
Right now we are trying to rescue 50GB of data that were on a reiserfs partition that got some bad sectors. reiserfsck says everything is ok, but when one tries to mount this partition, one gets an "Oops" and the mount process hangs.
And we had more of these problems on different computers. So now we will try XFS, both of my computers already use it as root file system and I have no problems yet :)
