I created a site FaceBoom Us. I wonder who will figure out how subversive this is of me? >:)

The Ball by John Elliot
The ball was sitting alone on the grass next to the mud. Bright orange, old, lumpy and misshapen. I kicked the ball into motion and on to the path. The ball rolled by itself through the landing. It seemed to know its path. Two loose pavers caught the ball and it recoiled. I kicked it over the loose pavers to the ramp. The ball sped down the ramp with all the self assurance in the world and almost got away from me. But due to its speed it rebounded in the gutter at the bottom. I kicked it out of the gutter and on to the court. The ball danced with me around the court, from time to time bouncing off the walls. The ball flew steadily back across the court and through the gutter which had previously repelled it. On the return journey back up the ramp the ball lost its way and got sidelined in the grass to the side. I kicked it back on track and up the hill. The ball came in to view of everyone on the landing between the benches. As it navigated the landing it cleared a twig, a small obstacle, by itself. I stopped the ball on the landing because it was headed into a closed corner edged by the garbage. The ball and I turned back and headed for the white path narrowly missing a large obstacle. The ball followed the white path largely by itself as it curved downhill, only twice needing to be nudged back into direction. The ball cleared the gutter by itself once again and drifted past the chairs and tables at the back of the court. The ball came to a stop at the stairs, bouncing softly backward. I carried the ball up the stairs and placed it in one of the two brown chairs in the light.

Chatting with Key about Angry Orange
Was chatting with Key about Angry Orange. I don’t think orange makes anyone angry.
Someone has almost certainly never spoken this sentence before.
“Someone has almost certainly never spoken this sentence before.”
Because colourless green ideas sleep furiously.
Oh, and:
“Someone has probably never spoken this sentence before.”
“No-one has spoken this sentence before.”
I win. :)
Thought for the day
Today I’m really worried that the computers are going to end up mind controlling the humans in our apocalyptic end. Well, not really worried.

You might get my cooperation, but you won’t get my obedience.

The amount of spam I’m receiving on this blog has just started to sky-rocket. I think shortly that comments will be disabled. It’s such a shame there are low-life spammers in the world.
The difference between absolute growth rate and relative growth rate
If you’re interested in this article about the difference between absolute growth and relative growth, you might also be interested in How to Lie with Statistics by Darrell Huff.
I searched the other day for the difference between an absolute growth rate and a relative growth rate, and didn’t easily find a helpful answer. I didn’t look too hard though.
Anyway, I figured it out just by thinking about it a little bit.
An absolute growth rate is given in units, while a relative growth rate is given as a percentage.
So, for example, I could have a growth rate of $100 per annum, or a growth rate of 10% per annum. The first growth rate is an absolute growth rate of $100 per annum, and the second rate is a relative growth rate of 10% per annum.
The difference is that an absolute rate just grows linearly, whereas a relative growth rate grows exponentially. So as the table below shows with $1,000 and an absolute growth rate of $100 per annum, after one year I’d have $1,100, after 2 years $1,200, after 3 years $1,300, and so on. Whereas with a relative growth rate of 10% after 1 year I’d have $1,100, after 2 years I’d have $1,210, after 3 years I’d have $1,331, and so on.
| $100 pa | 10% pa | |
|---|---|---|
| Start | $1,000 | $1,000 |
| After 1 year | $1,100 | $1,100 |
| After 2 years | $1,200 | $1,210 |
| After 3 years | $1,300 | $1,331 |
| After 4 years | $1,400 | $1,464.10 |
| After 5 years | $1,500 | $1,610.51 |
Maybe this explanation will help for someone the next time someone searches for the difference between absolute growth rates and relative growth rates.
Like the deserts miss the rain
I’ve always wondered about the metaphor “like the deserts miss the rain”… what is that supposed to mean? On the one hand, it doesn’t rain in the desert, so maybe the deserts miss the rain a lot. On the other hand, if it rained in the desert, then it wouldn’t be a desert any more, and that would destroy what the desert is, so a desert doesn’t miss the rain at all.
I don’t get it. Nice track though.
