You may want to save your selection of packages, in order to reinstall all your softs later without having to look for and manually install them one after another. On Debian / Ubuntu, this is quite easy. A while ago the solution used to be : $ dpkg –get-selections > file.txt and then, an a [...]

Hardware database for Linux
A nice website : http://hardware4linux.info/ Whith the provided script, you can upload your hardware information there and quickly rate your experience with it (for each equipment it detected). I just did it for my laptop and will go on with my other machines. It will probably become an interesting database.
Internet providers in France suck
And as a result, almost one day without Internet access. That why the website was done all this time. Really, there is an incredible amount of claims from many users here. My personal experience : – Noos, my actual provider : poor customer service, few interruptions but always long, quite expensive and behind technically speaking. [...]
Perl : how to monitor a service remotely using sockets
I came to program my first Perl script based on sockets, after setting an IPSEC tunnel.
This tunnel is linking the remote peer and the local peer through an OpenBSD VPN gateway (managed with Isakmp).
The problem is that this connection is limited time, for access right reason. So it is not a 24 hours standard tunnel, but rather an on-demand type connection.
Note that the connection is automatically reseted by the remote peer, by invaliding the cookie of the connection and therefore obliging to renegotiate the VPN tunnel from the beginning : phase 1 of the key exchange.
In one word, the Isakmp service has to be restarted every time we need the tunnel to be up.
Of course, this is not the purpose of Isakmp to have such a mecanism and what is interesting is to start the tunnel from the local peer, every time it needs to do some transfer.
The graph below summarizes the situation :
IPSEC tunnel with OpenBSD as a VPN gateway
That why I came to develop a script that listen on a socket and allow that peer to remotely restart the Isakmp service.
