An Australian technologist has caused a global stir after discovering Facebook tracks the websites its users visit even when they are logged out of the social networking site. Wollongong-based Nik Cubrilovic found out that when you log out of Facebook, rather than deleting its tracking cookies, the site merely modifies them, maintaining account information and other unique tokens that can be used to identify you.
Whenever you visit a web page that contains a Facebook button or widget, your browser is still sending details of your movements back to Facebook, Cubrilovic says. “Even if you are logged out, Facebook still knows and can track every page you visit,” he wrote in a blog post. “The only solution is to delete every Facebook cookie in your browser, or to use a separate browser for Facebook interactions.”
Cancer patients have been kept waiting so long to receive follow-up letters from their specialists that some have died before the advice arrived at their GPs. A backlog of correspondence needing to be typed up at Westmead Hospital means about 700 people have waited up to three years for the letters to be sent.
In one case, a Sydney doctor received a letter from Westmead about a female patient with advanced skin cancer that had been dictated by a specialist on August 21, 2009, but was not typed up until September 16, 2011. By the time it reached Dr Adrian Sheen the woman had been dead for a year.
