Redis is one of the simplest services I’ve used… we could flip the script and say “for many db use cases postgresdb is overkill, just use Redis… you get caching too”. I’m not sure exactly what this commentary adds to a real world architecture discussion. The whole thing seems a little sophomoric, tbh.

I’m currently working on a similar proprietary system that is similar to the one described in this article, and I can tell you that there is much more involved here than “counting people in a room”. Claiming someone with a clicker in front of a door is a better solution misses dozens of other use cases where this isn’t at all possible or cost effective...

But you know, everyone on HN is an expert in everything.

I think people think that shooting down ideas makes them sound intelligent and “in the know”, but in reality it just makes you sound rigid and not creative enough to see the merit in a idea.

This seems to be a common attitude on HN, but it’s less than useful. Genuine critical thinking is great... dogmatic cynicism is useless.
