depth first search

My recent tweet about combining Emacs and Python generated a pointer to Pymacs. Clearly I have a penchant for wishing for things that already exist. Is there a rule for that?

I thought this was a fascinating peek into the workings of the presidential limo. If you read closely (italics mine):

The only window that opens — by just three inches — so the driver can pay a toll or talk with secret service agents running alongside.

Has the president ever had to pay a toll?

I am in fact a scorpio.

I know this is a bit ridiculous, considering I’d never eat there, but the fact that it was a block away from where we use to live made me a bit nostalgic.

The NY Times review.

How can you have inverses but still have zero divisors, you may wonder? It’s because nonassociativity is bad juju.

From a comment on this.

Then there’s the following from the same comment thread:

There are illegal primes, but being prime numbers, they are inevitably real, positive, rational, integral, natural and wholesome.

A goldmine!

And here’s a spurious link to a comment on that thread that I might want to write about later.

My flight today had a maintenance issue. We were at the head of the runway and the engines had just come on full bore when the captain powered them down and taxied off. We then taxied all the way back to the gate. From what I gathered the problem was the equivalent of a check engine light coming on.

The solution was a good hard reboot. I’m not kidding. Total electrical shutdown and power on.

We must have been flying Windows.

I don’t know what to say about this.
