Summer days and nights of 2009

This video was recently featured on the HPC Wire YouTube channel. It is an animation of the summer weather of 2009, as only super computers can do! HPC refers to "High Performance Computing". Cray was one of several contributors to the project. I still think of Cray as THE super computer developer, though those days are probably past.


What's so special here?


A recent HPC Wire article about climate change explained why simulation at such a fine resolution (7-kilometer) was so difficult, because it required:
a special allocation of computing time on the Athena supercomputer at the National Institute for Computational Sciences (NICS)... For six months, the entire 18,048-core system was at the disposal of the team. Among the results ... were simulations that represented boreal summer climatology at 7-kilometer resolution
Notice shifting cloud cover and precipitation in shades of gray scale during the summer months of 2009. The quality is exceptional.

MintChip denouement

The Royal Canadian Mint is the official mint of the Canadian government. In March 2012, the Royal Mint announced that it would discontinue all future production of penny coins. A week later, the Toronto Star ran a news story, in which the Royal Mint introduced the first national digital currency in North America, the MintChip.

A Royal Canadian Mint spokesman provided the following description:
MintChip doesn’t plan to link to a person’s bank account or credit card information. And unlike BitCoin, a peer-to-peer hosted digital currency with a fluctuating value, MintChip is simply a new way to exchange Canadian dollars. Plus, it’s backed by the Canadian government. 
The MintChip doesn't satisfy criteria for what I would consider a bona fide currency. Rather, it seems more like a type of electronic payment network for the Canadian Dollar.

Golden prize


A rather intriguing contest, MintChip Challenge was announced in the same Toronto Star article. MintChip Challenge was an app developer contest sponsored by the Royal Canadian Mint, with top prizes to include the equivalent of CAD 50,000 of gold bars and coins, in gold bullion, i.e. 99.99% gold.

The top comment on the Toronto Star article offered this suggestion:
Did you know that one of the leading proposals for how to use MintChip is for purchasing bitcoin? Because of the irreversibility of MintChip transactions, this would solve a lot of issues. See paragraph 6 of MintChip Misses the Point of Digital Currency via Forbes.
MintChip Challenge generated much excitement. The 500 entry spots were filled in merely four days! Prize winners were to be announced on 25 October 2012.

What's up with MintChip? 


The official website hasn't provided much information. I was curious. Erstwhile gAt0mAl0 was curious too:
So what happened with MintChip – Canada’s digital currency? It has disappeared into the Bermuda Triangle of digital currency holes – a news blackout. 
The denouement of MintChip Challenge was distinctly anticlimactic. gAt0mAl0 explains more about the Canadian MintChip, and Bitcoins too. Alternatively, you may prefer to explore gAt0's rather impressive Bitcoin Mind map chart, featured in his prior post, Bitcoin and Forex Trading which I enjoyed much more than the entire MintChip mess, from start to muted finish.
