Guys what do you say about generics/templates vs interfaces

Other than "they're orthogonal"?

@denisgrebennicov Can you refine your question by providing some context?

@seancorfield the question is more directed to which of one should be preferred to be used. When should one use templates/generics and when interfaces

templates & generics solve copy + paste problems. Interfaces solve “everyone must implement the same API” problems

for anyone interested, I’m going to be trying to do Advent of Code in both CLJ and Rust: https://github.com/Lokeh/advent-2018/tree/master/day1

Nice, I try rust and RxJava, you might want to give https://github.com/gobanos/cargo-aoc a try for rust, makes it really easy to focus on the solution. Didn't found the cycle input, gonna check if it will perform better.

Very cool. I think I'll stick with just using plain cargo for now; I'm using this to learn how to use and setup cargo as much as for learning the language

I'm sure at some point between now and the 25th I'll get sick of it and use the fancy plugin:stuck_out_tongue_winking_eye:

They are planning on having a kind of leaderboard based on performance. That could be nice. I also added some timer to JavaRx, but it's about 10 times as slow as rust

lilactown01:12:07

yeah my Clojure solution took ~~300ms on my dinky VPS I’m sshed into. My rust solution built with —release took~~ 20ms

gklijs12:12:18

I now also set the JavaRx up to properly test with jmh, warming up the JVM and such.
