Dropbox's core product is trying to tack on P to CA systems. The CAP theorem explains how well this will actually work out. It's good they raised a bunch of cash, because they need to diversify their product base beyond that confu

Node isn't great at async, despite the hype. Important things are still synchronous, most notably the GC, so you can very easily wind up with service stalls at scale. The module churn in Node land means that few things are actually bat

A thread pool is far from "ergonomic", it's accidental complexity with numerous gotchas.

async/await still has the fundamental problem of composability that all the other attempts at sugaring around an event loop have (aka the "functions have colors" problem [1]). It sucks for collaboration, which is one of the m

Thank you for articulating what was behind the Mossberg phenomenon in a positive way. An anecdote: About a decade ago, I was working at a startup. The VP of Marketing got it into his head that we just had to get Mossberg to write about us
