The hazards of restricting supply

An object lesson for city policy-makers – this is what happens in Dogtown when supply is restricted. Of course we humans would eliminate the queue by selling the tree to the highest bidder! Read the rest of this entry »

Google Maps captures flying pliers

Amazing photo of a pair of flying pliers captured by a Google Map’s camera car in the West Midlands, UK. This appears to be a genuine stuff-up rather than a Photoshop exercise. Go here and move around the street. Perhaps some tool (geddit?) sneaked up to the car and put pliers on the lens of one of the cameras. Enjoy it while it’s still ‘in the wild’.

Question time

My son and I attended the great debate at Melbourne Town Hall on March 4 where the proposition under debate was “that Australia should embrace nuclear power”.

As a consultant myself, I think there should be a separate “marketing” category, too.

What the bookies are saying about the Federal election

If you’re pondering who will win the next Federal election, you might want to take note of what the bookies think.  According to Pollytics yesterday, the current implied probability of the outcome (derived from the odds offered by the five main betting houses) is 74.4% ALP and 25.6% Coalition.  The ALP was 77.9% a month ago.  The trend is down for the ALP but they’re still looking damn good.  BetFair has the ALP at $1.30 and the Coalition at $4.00.
