On Concurrency

Some developers I’ve known seem to think that being good at concurrency makes them badass. Others seem to think that senior developers must be great at concurrency, and so they should be too.

Tesla Model Y Temperature Efficiency

We’ve had a Model Y since last September and have been tracking drives with TeslaFi. It’s been interesting to see how much the ambient temperature affects the range of the car.
