It was the same merchant, but the limit was set to the cost of the first purchase and the number was set to expire three days later, at the end of the month. The second purchase was well over the limit on its own, and as well as a couple weeks past the expiration date.

The article was interesting, but I disagree with their claim that, "TurboGears is more community-driven than Django because it was built with pre-existing, open source components." From everything I've seen, Django has a strong community behind it. I don't think I've ever seen an open-source project whose maintainer is as helpful to users and contributors than Adrian Holovaty is. He's extremely respectful and responds quickly to bug reports and suggestions. In addition to its clean, unified feel, the community is one of the main reasons I was attracted to Django.

Hate to be picky, but muons are actually considered pretty long lived. They have a half life of over 2 microseconds. That sounds short, but it's a lot longer than a free neutron (for example), and it means they're really useful for probing materials.
