"Since occupancy determines flow rate, there’s not much benefit to trying to 'cancel out' a traffic wave by leaving a ton of space in front of you. No matter what you do, you’re not going to get to the front of the line before the car in front of you. Worse, by leaving space in front of you, you’re artificially reducing the occupancy of that part of the road, but since you haven’t changed the number of cars trying to use the road, this comes at the expense of increased occupancy somewhere else."

"What we experience when we listen to sad music might be thought of as 'vicarious emotions.' Here, there is no object or situation that induces emotion directly, as in regular life. Instead, the vicarious emotions are free from the essential unpleasantness of their genuine counterparts, while still drawing force from the similarity between the two."

Natasha moving from fifth grade down to kindergarten provided me the opportunity to re-architect her classroom’s computers. I decided to complete the Raspberry Pi terminals I started in her fifth grade classroom.

Saw a "Baby on board" sticker on a refrigerator during my morning run. I paused my run to verify it wasn't true.

RIP Douglas Engelbart. As VentureBeat put it, calling him the inventor of the mouse is "a bit like saying Henry Ford was the inventor of the steering wheel." Mr. Engelbart's vision extended far beyond the pointing device.

Lots of qualifications in the results: participants were overweight and sedentary (but otherwise healthy), fitness levels increased but no weight loss. Nonetheless this indicates a smaller first step for those intimidated by the thought of starting a workout routine.

"After briefly warming up, [the first group] ran on a treadmill at 90 percent of their maximal heart rate […] for four four-minute intervals, with three minutes of slow walking between, followed by a brief cool-down. The entire session was repeated three times a week for 10 weeks. ¶ The second group, however, completed only one four-minute strenuous run. They, too, exercised three times a week for 10 weeks. ¶ At the end of the program, the men had increased their maximal oxygen uptake, or endurance capacity, by an average of 10 percent or more, with no significant differences in the gains between the two groups."

"The difference between a perfectly balanced cocktail and a so-so one often comes down to ice. How does ice affect temperature? Dilution? Since as much as half the volume of a cocktail can be melted ice, why not pay a little more attention to what you put in your glass?"

"A principle for thinking in a digital world, in two parts: First, acquire a base of fact knowledge in any domain in which you want to perform well. This base supplies the essential foundation for building skills, and it can’t be outsourced to a search engine. Second: Take advantage of computers’ invariant memory, but also the brain’s elaborative memory. Computers are great when you want to store information that shouldn’t change—say, the date and time of that appointment next week. […] But brains are the superior choice when you want information to change, in interesting and useful ways: to connect up with other facts and ideas, to acquire successive layers of meaning, to steep for a while in your accumulated knowledge and experience and so produce a richer mental brew."
