150-200k is also just the employee’s salary, the actual cost to the company is significantly higher, you need to multiply that by something like 1.5 to get the fully loaded cost, people are expensive!

I haven’t used Ruby much, but anecdotally I once rewrote a Ruby service in Java and was able to reduce the number of servers needed from ~100 to 10. That was a case where it was “frustratingly slow” in practice.

Unity's burst compiler https://docs.unity3d.com/Packages/com.unity.burst@1.2/manual... uses LLVM, but only supports a somewhat limited subset of C#. I've used it a bit in some performance critical parts of a game and saw some dramatic speed increases. But I can't speak to other parts of the C# ecosystem beyond Unity though.

Maybe i'm misunderstanding, but wouldn't this mean that there would be no way to safely remove a relationship? I guess there are a number of cases where this would be ok.

But people tend to make mistakes. When you discover that someone has added a link between Daniel Day-Lewis and Ernest Goes to Jail all you would need to do is delete a row in the movies_people table. But because of potential collisions in the bit arrays you can't safely remove a relationship?

I recently moved to the East Bay from Los Angeles - I gave up on even trying to find a place to live in SF. I'm paying 2X the rent I had in Silver Lake (which is a relatively expensive part of LA) and competition was so tough I had to go to over 10 open houses just to find something decent a landlord would rent to me. Even the East Bay is pretty insane right now.

The "Getting started with" guides at http://aws.amazon.com/documentation/ec2/ are great. Once you're done with those might as well just read the docs at there too.
