I have observed that the Pillars of creation image from the Hubble space telescope is stair case shaped on the top right. Today I actually found explanation for that!

It seems that there are actually 4 cameras in there and that one of them captures a larger view compared to the other three. The view from the larger camera is then shrunk to produce a normal picture, resulting in the stair shape.

See here for more details.

Ah, feels good. I many times feel like writing software that other people can use to get something useful done. This has happened after years. I wrote a simple Python + GTK application that manages virtual machines under the OpenVZ kernel.

OpenVZ is a operating system level virtualization solution that lets users run many instances of virtual servers(each can be a different distro) on the same hardware. Whats more, the overhead is almost negligible.

EasyVZ is currently alpha quality software and definitely contains bugs and incomplete features and is released in the spirit of “releasing early”.
