junior level error, dont understand whats to talk here about... Use ConcurrentSkipListMap and never write our own concurrent data structure unless you Doug Lea

How about the senior engineer level error of forking Doug Lea's concurrent data structures only to make them operate in worst-case time complexity? Found this doozy recently.

we are not in 2010, why use rail? There are a lot of alternatives - java (spring) - go - node. But using rust for it is not far from c++ by craziness. So you are jumping from one strange solution to another…


Because Rails solves problems the others don't.

Also,

1. Spring outdates Rails (2002 v 2007)

2. Go is a language, Rails is a platform, Ruby is the language. Ruby and Go solve for different problems, Go doesn't have a singular web application framework to compare well to Rails

3. Node is a runtime, not a language or a platform. There's no direct comparison there.
