da: A smiling human with short hair, head tilted a bit to the right. It's black and white with a neutral background. You can't tell if the white in the hair is due to lighting, or maybe it's white hair! (Default)
The first thing anyone said to me yesterday morning was "I've seen two people killed right here." Salt and pepper beard, bike helmet. We were waiting for the light to change at the edge of the University, and had just watched a young guy, no helmet, bike out in front of a car. We chatted a bit. He's been working here for 20 years.

Today my jacket smells wonderful, like garlic and onions. Last night I made a convert to the joys of Spanish Potato Tortilla. It's a really easy recipe, except for the next-to-last step of "when it's half-way set in the middle, flip it onto a plate then slide it back into the pan." Which is always much easier than it sounds. I'm thinking about making an Instructable.com video or something, because tortilla's just too tasty to not share.

Finally: I like when powers of two show up in the day-to-day (what, me, geek?). Dan pointed out to me recently that miles-to-km is much more accurate at 8/5 than 3/2. On my commute this morning I had a (very small) realization that if your miles happen to be a power of two, you always get powers-of-two on both sides. And it's an easy calculation: multiply by 16 (bit-shift right 4) and divide by 10. So: more accurate than 3/2, quicker if you remember your bit-shifts, and more satisfying numbers too. 160 miles? 256 km. (only 1.49km off the real value). Going the other way, km-to-mile is divide by 16 and multiply by 10. 1024 km? 640 miles. See? Satisfying. At least, if you're me. :)
