Multimonitor support in Xubuntu 13.04

One new feature planned for the Xubuntu 13.10 release is the multi-monitor support integrated into XFCE desktop. Previously one would have to use xrandr to adjust monitors settings and now it should also be possible with the updated Display Settings dialog. But it is also possible to use this feature in Xubuntu 13.04

Javascript vs Perl vs Python vs Lua speed comparison

I have previously compared performance of the three most popular interpreted languages - Perl, Python and Lua (part1, part2). The next question was - how do they compare to the Javascript? Unlike the above mentioned languages it was quite unusual to use Javascript outside of a browser sandbox but with developing of the node.js this became possible.
