As you might have noticed, WordPress 2.5 is out, so I’ve just upgraded this blog.
Till now all I can tell is that the admin interface has changed a bit. Oh and there is a system to upgrade plugins with one click, which is way cool. Otherwise pretty much the same good old WordPress.
The upgrade went smoothly, just as for any other previous release and everything seems to be running just fine. However, at the first glance, the blog seems a bit slower than before the upgrade … (maybe this is not related to the upgrade … I’ll have to check this out).
Edit : The slow feeling is away, so I guess it was something totally unrelated to the upgrade.
A cool feature of WordPress I’ve just discovered : delayed posts.

Happy Easter to everyone ! Enjoy the chocolate
A common problem when you deal with a pool of servers (clusters or server farms, you name it) is to execute the same command line on each server. It is usual to solve this with a “for” construct such as :
for i in server1 server2 ; do ssh $i "uname -a"; done
I’m back from a 3-day-training about clusters with Linux which was pretty exciting, and here are the main points which were covered :
This little Perl one-liner can get handy when you need to translate “time in seconds since the Epoch” (for example in logs) to local time :
% perl -e 'print scalar(localtime(1202484725)), "\n";'

This was pretty useful today when browsing through Nagios event logs, where times are given in seconds from the Epoch.
By the way, the Epoch is defined as 00:00 UTC on January, 1st, 1970.
