Tom's Hardware ☛ How to turn an old PC into a Linux web server
The first web server was a desktop computer. Specifically an NeXTcube computer, at CERN — taken from the French “Conseil européen pour la Recherche Nucléaire” and translated into English it is European Organization for Nuclear Research — which is based in Meyrin, on the France-Switzerland border. A note stuck to the computer “This machine is a server do not power down”, instructed that the computer must not be switched off, otherwise the first web server would go offline.
From those early days, the web has grown into the labyrinthian behemoth that we have today but we can still make a web server from a desktop computer.

Étienne Pflieger ☛ Empty SSH agent before sleep
I use SSH keys to connect to the remote servers I manage. As those keys are password protected and it can be tedious to enter (long, complex) passwords multiple time per day, I setup an agent a long time ago to unlock keys once in the morning and then forget about them.
The only problem I realize recently was that the agent did nothing specific when I put my computer in sleep (going to lunch, answer a call, whatever). This means that all my keys are still loaded in memory and a well equiped attacker might access them. Or if a less equiped attacker discover my session password, he can also log in to any server.
The solution chose is to empty the SSH agent each time my computer goes to sleep. It means that after each resume I have to enter again the keys passwords, but this is a good compromise for security.

Ben Jojo ☛ Picking uncontested private IP subnets with usage data
For the average user, the choice of address range does not matter as the only purpose of the network address is to communicate with the outside world (via translation) or to talk to devices inside the same LAN without any IP routing.
However a large problem begins to show up when you wish to actually IP route between these private address ranges, in the they are not guaranteed to be unique between two different sites (especially in the case of company mergers), so when routing two networks with private addressing together there is a high chance that there will be a conflict somewhere.
