London Law is an online multiplayer adaptation of the classic Scotland Yard board game (also see Wikipedia), first published by Ravensburger in 1983. The game is unusually asymmetric; one player controls the movements of the criminal Mr. X as he tries to evade Scotland Yard, while another one to five players control five detectives trying to track him down. Mr. X has an advantage in access to transportation routes, and his precise location remains hidden for most of the game. The detectives have only the advantage of superior numbers, so they must work in concert to limit the criminal's options. London Law features an attractive map overlaid on high-resolution satellite imagery.

Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP server. It is designed to provide DNS and optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.

Duplicity backs directories by producing encrypted tar-format volumes and uploading them to a remote or local file server. Because duplicity uses librsync, the incremental archives are space efficient and only record the parts of files that have changed since the last backup. Because duplicity uses GnuPG to encrypt and/or sign these archives, they will be safe from spying and/or modification by the server.
