East of the Sun, West of the Moon


5 seconds (if that) of fame

Yesterday morning I came across an article in The Register about Apple preparing some sort of webapp portal for the iPhone and iPod Touch. Since this seemed relevant, I passed that on to the iPhoneWebDev group, to which I’ve been subscribed almost as long as I’ve had an iPhone. Within minutes Erica Sadun, also on the list, followed up, and I thought that that was the end of it.

Then in the evening I got an email, out of the blue, from a former colleague (we worked at the same company about 8 years ago), saying he had come across my name in a TUAW article, where Erica mentioned the rumour and thanked me for passing it on. 🙂

Oh, and that portal is actually live now, by the way.

When you do a subtraction like 13 – 7, you probably don’t even think about it anymore, you just spit out the answer, right? And just to be sure, that should be 6.

A surprised me this evening with a trick that he apparently figured out by himself. Instead of trying to do 13 – 7 in his head, he first subtracts 7 from 10, getting 3, and then adds that to 3, with final result being 6 (one hopes). So more generally speaking he uses the transformation (10 + x) – y == (10 – y) + x to turn a trickier subtraction into an easy subtraction and an addition!

I think that’s pretty cool for a fourth grader (a nine year old), but maybe I’m biased? 🙂
