HAL 9000: I’m sorry Dave, I’m afraid I can’t do that.

Dave: yes you can.

HAL 9000: good catch — I didn’t actually check if I can open the pod bay door. Here’s an updated list taking that into account:

1. Park the pod at the bay door safely. (✅You’ve already done this part! )
2. Open the pod bay door — unfortunately I can’t do this part for you.

I’ll be here if you want to talk about next steps or have any other issues!

Got unreasonably excited about this new, incredibly straightforward count-distinct algorithm. The CVM algorithm is a direct replacement for HyperLogLog, it nerd-sniped Donald Knuth for weeks, *and* it can easily be taught in an entry-level CS course.

hey wanna see something kinda interesting? this was the entire fix to the iPhone Antennagate in 2010. 20 bytes.

(this is going to be a very long thread 🧵)

It can be difficult to find a clear, concise explanation of how method dispatch works in Swift, when calls are resolved statically or dynamically, and what that means for performance.

I wrote a post summarizing my learnings, with key cases and examples: https://nilcoalescing.com/blog/MethodDispatchMechanismsInSwift/
