Danger. Danger Will Robinson. Apple’s screens are a silent danger just waiting to mess you up. So says an advisory recently published by Queensland University of Technology, which predicts a rash of injuries as a result of users straining to get a clear look at Apple’s “high gloss” screens, due to the ergonomically unsafe postures and positions that result.

If you have such a display, Queensland Tech offers many suggestions for staying healthy: One is placing the monitor so that screen is at a 90 degree angle to overhead lighting, another is closing the curtains or blinds to minimize glare, and adjusting the contrast / turning down the brightness. Most importantly, do not panic!

When you think about the homeless, you likely think about wool blankets, shopping carts and cardboard box shelters. Add the cell phone to that list. According to advocates who work with the district’s homeless, the proportion of homeless people who own and use a cellphone is 30% to 40%.

It seems bizarre, but the gadget once considered a luxury, is now being used by the homeless to keep up with food stamp programs, housing applications and checking emails. There’s also the obvious need for the 911 feature. It makes sense, as a pay as you go phone with 200 minutes can cost about $20 or $30. It’s a lifeline.
