Yes, absolutely. I worked there about 7-8 years ago and at the time it was considered a "retirement home" in Silicon Valley.

The problem can be solved in two different directions - accepting fewer immigrants or building more housing (perhaps both for some stretch of time to ensure that citizens can afford housing and build families).

Long-term though I don't see a way for the Anglosphere to thrive unless immigration increases, given low birth rates.

And indeed, the author mentions exactly this:

An engineer with no such customer awareness and instead an incessant obsession with optimizing everything that can be optimized, might try to optimize for speed… when it’s likely the consumer cares more about: cleanliness, energy rating and capacity.

1. Redis is atomic, so we use the SETNX operation to ensure that only one write succeeds.

2. We have HLLs in Redis, so we just issue a PFCOUNT and store the result of that in Cassandra as an integer value. We don't use counters in Cassandra.

Pretty much, yeah.

Yup! Just bear in mind that since the feature is only open to mods and OPs, the API is similarly restricted.

Not at the moment, but we might do that in future.
