+ - SPAM: Satellite glitch rekindles GPS concerns

Submitted by

coondoggie writes "News today that Air Force is investigating signal problems with its latest Global Positioning System satellite are likely to rekindle the flames of a congressional report last month that said the current GPS coverage may not be so ubiquitous in the future. The Air Force stated that routine early orbit checkout procedures determined that the signals from the Lockheed-built GPS IIR-2 (M), which was launched in March, were inconsistent with the performance of other GPS IIR-M satellites. The Air Force said it has identified several parameters in the GPS IIR-20 (M)'s navigation message that can be corrected to bring the satellite into compliance with current GPS Performance Standards.

+ - Marijuana smoke damages DNA-> 8

Researchers from the UK and Sweden have discovered that smoking the cannabis plant causes DNA damage that could potentially lead to cancer. Because cannabis is less combustible than tobacco, the report states that it has 50% more carcinogenic polycyclic aromatic hydrocarbons. And what's more, there is the added danger of smoking technique: marijuana smokers inhale more deeply, meaning 3-4 cannabis cigarettes a day is equivalent to 20 tobacco cigarettes."

It may be a lame april fools joke, but in the long term I wouldn't be surprised if stuff like this starts to happen. There are already a lot of news organizations that put out updates via Twitter. 140 characters a little hard to fit an entire news story in, but people are giving less and less attention to the news these days anyway.

Real Users find the one combination of bizarre input values that shuts down the system for days.
