Fortaleza del Cerro overlooks the bay of Montevideo. An observation post at this location was first built by the Spanish in the late 18th century. In 1802, a beacon replaced the observation post; construction of the fortress began in 1809 and was completed in 1839. It has been involved in many historical developments and has been repeatedly taken over by various sides. In 1907, the old beacon was replaced with a stronger electric one. It has been a National Monument since 1931 and has housed a military museum since 1916. Today it is one of the tourist attractions of Montevideo.

The first major model for communication was introduced by Claude Shannon and Warren Weaver for Bell Laboratories in 1949 The original model was designed to mirror the functioning of radio and telephone technologies. Their initial model consisted of three primary parts: sender, channel, and receiver. The sender was the part of a telephone a person spoke into, the channel was the telephone itself, and the receiver was the part of the phone where one could hear the other person. Shannon and Weaver also recognized that often there is static that interferes with one listening to a telephone conversation, which they deemed noise.

In July 2012 a United Nations Special Rapporteur called on the Tuvalu Government to develop a national water strategy to improve access to safe drinking water and sanitation. In 2012, Tuvalu developed a National Water Resources Policy under the Integrated Water Resource Management (IWRM) Project and the Pacific Adaptation to Climate Change (PACC) Project, which are sponsored by the Global Environment Fund/SOPAC. Government water planning has established a target of between 50 and 100L of water per person per day accounting for drinking water, cleaning, community and cultural activities.
