How much checking do we perform that our code is running as intended? I found a curious bug this weekend, which made me think about some of the assumptions that we use when programming. Imagine sorting an array using JavaScript. var arr = [10, 5, 66, 8, 1, 3]; arr.sort(); So far, so normal. Create an array of numbers, then sort that array. The result should always be [1, 3, 5, 8, 10, 66]. …

*And a telescope.... The photo on the left is me just pointing my Galaxy Note II at the sky - the one on the right uses the same phone, but with a bit more kit...

There's also a lot of misinformation, folklore, and crazy thinking which confuses us when we try to interact with "simple" technology. For example, I was in Waterloo Tube station when…

While visiting the USA, I came across a delightfully bizarre TV show - Doomsday Preppers. For those who don't know, this pseudo-documentary follows the lives of certain... eccentric... families who believe that the end of civilization is coming and they better get busy preparing for that eventuality. Whereas you and I might keep a bit of spare cash hidden away, along with some out-of-date cans…

A finger pointing at a Samsung phone's dialer.

I have discovered another security flaw in Samsung Android phones. It is possible to completely disable the lock screen and get access to any app - even when the phone is "securely" locked with a pattern, PIN, password, or face detection. Unlike another recently released flaw, this doesn't rely quite so heavily on ultra-precise timing. Video. Of course, if you are unable to download a…

Way back in 2010, I got a pair of video recording sunglasses. I've been occasionally using them to "lifelog" what I'm doing. With the advent of Google's Project Glass, I thought it would be interesting to wear them to a fairly techy event - Not At SXSW London - to see what the reaction would be. Here are my findings. Caveats These are not Google Glasses. These are £15 DVR Sunglasses. They …
