Professor Landfeldt, one of Australia's leading
telecommunications experts, says some of the fundamental flaws of
the scheme raised in his report include:
� All filtering systems will be easily circumvented using
readily available software.
� Censors maintaining the blacklist will never be able to
keep up with the amount of new content published on the web every
second.
� Filters using real-time analysis of sites to determine
whether content is inappropriate are not effective, capture wanted
content, are easy to bypass and slow network speeds exponentially
as accuracy increases.
� Entire user-generated content sites such as YouTube and
Wikipedia could be blocked over a single video or article.
� Filters would be costly and difficult to implement for
ISPs and put many smaller ISPs out of business.
� While the communciations authority's blacklist would be
withheld from internet users, all 700 ISPs would have access to it,
so it could easily be leaked.
� The filters would not censor content on peer-to-peer
file sharing networks such as LimeWire, chat rooms, email and
instant messaging;
� ISPs and the Government could be legally liable for the
scheme's failures, particularly as content providers have no right
to appeal against being blocked unnecessarily.

Not necessarily. But securing the future will require fixing a system that has become a joke.

By Rachael Brown Chart: "The Happiness Index" Times were tough in 2009. But according to a cool Facebook app, people were happier. By Justin Miller On August 25, 2008, two little boys walked into public elementary schools in Southeast Washington, D.C. Both boys were African American fifth-graders. The previous spring, both had tested below grade level in math. One walked into Kimball Elementary School and climbed the stairs to Mr. William Taylor's math classroom, a tidy, powder-blue space in which neither the clocks nor most of the electrical outlets worked. The other walked into a very similar classroom a mile away at Plummer Elementary School. In both schools, more than 80 percent of the children received free or reduced-price lunches. At night, all the children went home to the same urban ecosystem, a zip code in which almost a quarter of the families lived below the poverty line and a police district in which somebody was murdered every week or so.

After a year in Mr. Taylo
