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.
Nigel Coutts on 20 Sep 15'Inside the Black Box' was written by Black and William in 1998 and in it they describe the classroom as a black box with inputs and outputs but what occurred inside was a mystery. For many teachers the reality has been that what occurs in their classroom has been both private and isolating, a matter between the teacher and his or her students but a task largely tackled alone. But this isolationist view is, in the age of the social media and networking increasingly challenged and more and more teachers are finding their voice, sharing their ideas and gaining valuable insights from a global community of connected educators.
