• One of Michael Moritz's best stories on obsession is about the ride he got from Bill Gates when Microsoft was still private. "Bill Gates gave me a ride to the airport in his car. The radio was missing in the car, a big, gaping hole in the dashboard. I said, Bill, what happened to you, did you get ripped off? And he said no, I had it taken out. Why'd you have it taken out? Well, I drive from my home to the office, which is 7 minutes and 32 seconds, and then I'll drive from the office to the airport, which is however long.

So let me repeat (Reaction to comments about Greece and the like. ) The argument that the cancelling of the public debt by the central bank has either zero or a negative effect, the argument that I have made this week, is not an argument about debt cancellation in general. Debt (partial or full) cancellation (or restructuring, or reprofiling) of the debt held by investors is a whole different ballgame. It has big real effects. It decreases the interest rate charge, but makes it harder to issue more debt: Creditors, who just lost money, are…

Back then multiple bounces was the norm due to HDDs. One bounce really wasn't possible until SSDs. We've lost this obsession and its time to bring it back.

• When evaling models, we anchor on the median task. But this is like how devs estimate the median task accurately but underestimate the mean which tends to be ~2x estimated (thus "double your estimates"). This applies to models too—we optimize for time/cost on median tasks. But it's the tail tasks that determine a project's completion, and reliable models (like Fable and Opus) are the diff between success and failure. Work with models as collaborators, not tools. Go beyond pair-programming, where given a narrow spec, the tool just executes in minutes. Instead, explain your intent and what succ…
