Ice Spikes: Strange things you can find in your freezer
Temperature is certainly a factor when growing ice spikes, and we have done experiments that show that spikes are more likely to form when the temperature is just below freezing (see the graphs below). I'm not entirely sure why this is so, but I suspect that the ice tube freezes shut before the tube gets very long if…
Strategy and criteria decision matrix: A framework for decision making
I attended a talk by Evan Moore a while ago, where he described a framework the early team at Doordash used to make decisions and prioritize growth strategies.

Twitter, when the wall came down
I, like many people, have a complicated relationship with Twitter. As Adam and I regaled in a recent Twitter Space , it started when debugging the Twitter fail whale in the offices of Obvious in 2007, where I became thoroughly unimpressed with their self-important skipper, Jack Dorsey.

These days, a Common Lisp programmer is as likely to use a vector, a hash table, or a user-defined class or…
