Ruby 2.5.0 Released
I started using Ruby only in April this year due to starting at a new job. Having used and/or dabbled in C, Java, Python and Haskell before (amongst others), I find it super interesting to see how Ruby manages to take some interesting parts from each and manages to integrate it into a very pleasant programming experience. Also the rspec testing library is nothing short of magic, none of the compiled languages have anything that even comes close IMO.For the cases where you have a tight loop taking up 99% of the actual CPU time it is also relatively easy to hook in C or Rust or whatever. Also, sometimes you hit hardware performance limits regardless of the language you use. We have some streaming download servers written for 99% in Ruby using the libCurl bindings that and they easily manage to fill up the 5 Gbps pipe* per server that AWS gives us.* You can get 20 Gbps for some instances, but only to other instances in the same group. The biggest to the 'outside' seems to be 5 Gbps.
