It's a quote about slippery slopes that uses discrimination as an example. As is popular with that quote, we could adapt it into something a bit more applicable:
They first made us run our shoes through the X-Ray machine, and I complied because it wasn't that big a deal.
Then, they installed the full-body scanners, and I complied because I just wanted to get home for Christmas.
Then, they started requiring social security numbers when buying plane tickets.
Then, they began keeping all air travellers' fingerprints and retina scans on file...
The question is not against whom they're discriminating (clearly, that's not applicable in this case), it's to what length they (and, by extension, we) are willing to go.
Cython is also an amazing way to write Python bindings. CPython is too heavy and complex, ctypes is too annoying and verbose to write, and Cython is a staggeringly perfect DSL for walking the line between C and Python.
I've climbed in them before, and they're a bit different to climb in than specialized climbing shoes (I wear 5.10 spires normally). The rubber on the FiveFingers model I tried wasn't as tough as the 5.10 Stealth (which is likely different depending on the Fivefingers model), and climbing shoes also have much better ankle support. In particular, my Spires have a band of thick, tough rubber that covers the Achilles tendon, which is brilliant for heel-hooks. The Fivefingers, lacking that support, made moves like that more difficult.
This approach has worked well for the folks at Monome, who make small runs (generally 100 to 200) of their flagship human interface devices a few times a year. They no longer take preorders, instead just publicizing the date and time at which orders will be open. Generally, they sell 100-200 devices within a week, and have several times sold out in under 15 minutes.
