Climate change

Of ice and men

Aug 29th 2008

Arctic sea ice is shrinking at an alarming rate

THIS week scientists at the National Snow and Ice Data Centre gave warning that Arctic sea ice has receded to its second-smallest area since satellite records began in 1979. The rate of shrinkage this year is the fastest ever and, with around a month still left of summer, the current ice coverage of 5.3m square km could fall to less than the record low seen last September of 4.1m square km. This is bad news for the environment: Arctic ice reflects sunlight, keeping the region cool, and polar bear populations are predicted to fall by a third over the next 50 years as the creatures’ habitat disappears.

How Hybrid Cars Work

by Karim Nice and Julia Layton

Any vehicle that combines two or more sources of power that can directly or indirectly provide propulsion power is a hybrid. Most hybrid cars on the road right now are gasoline-electric hybrids…

Save time managing your social networks-Social Network Aggregation

Posted by Michael in April 13th 2008
-
With today’s Web being more social and average Web users having more than one account in several of these sites, be it MySpace, Twitter, LinkedIn, Digg or YouTube, it is becoming increasingly cumbersome to manage each account individually. A new wave of social aggregation services aims to make our online social lives a little easier by displaying information from each social networking site in a single location–where one can keep track of every inane action of their friends through feeds. Today there are dozens of social aggregation services including FriendFeed, Spokeo, Iminta, Dandelife,  and SocialThing! among other start-ups.

US campaign funding

Big bucks

Jul 7th 2008
From Economist.com

Presidential candidates are raising and spending more money than ever

WITH four months still to go, the 2008 presidential race is set to be the most expensive in history. Spending by all candidates has already surpassed the previous high of $823m (at 2008 prices). One notable development in the campaign is Barack Obama’s ability to raise money from small individual contributions of under $200. Of the $287.4m in his coffers, $135.7m has come from donations under $200. John McCain has raised just $32.3m of his smaller $104.6m war chest from such contributions. With an eye on this considerable gap, Mr McCain has accepted public funding and will be restricted to a spending limit of $85m. By contrast, Mr Obama’s controversial rejection of public cash means he is free to spend as much as he likes.

Mobile Telecommunications and Economic Growth

Author

Leonard Waverman, Meloria Meschi & Melvyn Fuss

London Business School, Law and Economics Consulting Group (Waverman), University of Toronto (Fuss)

…the economic impact of communications systems by highlighting its contribution to the organisation of business life, organisation of household and community life, and productivity of firms and workers. Communications systems – particularly those that are two-way (telecoms) rather than one-way (broadcasting) – lower transaction costs and widen buyer and supplier networks. Thus, the authors claim that a solid communications network is a key contributor to social overhead capital (SOC) – roads, telephones, electricity grids, etc. – which is, in turn, crucial for economic growth…

Africa, Offline: Waiting for the Web

By RON NIXON
Published: July 22, 2007
—

Attempts to bring affordable high-speed Internet service to the masses have made little headway on the continent. Less than 4 percent of Africa’s population is connected to the Web; most subscribers are in North African countries and the republic of South Africa.

A lack of infrastructure is the biggest problem. In many countries, communications networks were destroyed during years of civil conflict, and continuing political instability deters governments or companies from investing in new systems. E-mail messages and phone calls sent from some African countries have to be routed through Britain, or even the United States, increasing expenses and delivery times. About 75 percent of African Internet traffic is routed this way and costs African countries billions of extra dollars each year that they would not incur if their infrastructure was up to speed.

Satellite Services: Phone – Internet

Satellite phone:is a type of mobile phone that connects to orbiting satellites instead of terrestrial cell sites

http://en.wikipedia.org/wiki/Satellite_phone

Could this be the decade that the U.S. will get satellite media broadcasts to our phones? DMB, which is a method to send audio and video through satellites straight into small devices like phones and PMPs, may be touching us sooner than we think and Samsung is ready.

How does satellite internet operate?

satellite internetsatellite TV

http://computer.howstuffworks.com/question606.htm

Satellite Internet does not use telephone lines or cable systems, but instead uses a satellite dish for two-way (upload and download) data communications. Upload speed is about one-tenth of the 500 kbps download speed. Cable and DSL have higher download speeds, but satellite systems are about 10 times faster than a normal modem.

Mediterranean Fibre Cable Cut – a RIPE NCC Analysis

Analysis by the RIPE NCC Science Group with contributions from Roma Tre University.
Editors: Rene Wilhelm, Chris Buckridge

—

The history of submarine telecommunications cables goes back to 1850 when the first international telegraph link between England and France was established. Eight years later the first trans-Atlantic telegraph cable linked Europe to North America.

In the 20th century telephony became the driving force for submarine cable deployments. TAT-1, the first trans-Atlantic telephone cable, was installed in 1956; it had the capacity to transmit 36 analog phone channels simultaneously. These days fibre-optic submarine cables carry the bulk of the trans-oceanic voice and data traffic. Maximum capacity is now in the order of 1 Tb/s, equivalent to 15 million old analog phone calls. Compared to satellites, submarine cables offer higher capacity and, because of the shorter distance, feature much better latencies.
