I love Ruby and great to see Ruby love on hacker news. Just curious on how popular it is in the hacker news community ?
Seems to be well represented by successful companies here.
As I get older the question I ask myself is do I honestly enjoy using it? If the answer is yes, then I put it in my programming toolbox and ignore the hype.
However, now I’m on the operational side of things, and there are 2 types of applications I avoid to deploy/maintain, mainly because of their runtime: Java and Ruby apps. It’s very likely the Ruby runtime has improved, but we actually set up a haproxy with multiple instances of the same ruby app, which we just restarted every 2 hours, just to keep it running properly. Upgrading ruby back-then was a mess, and could break a lot of things. I can’t comment on the language itself, but the runtime left a very bad impression. I since then (4/5 years ago or so) have successfully avoided ruby, so it’s possible things have improved, but first impressions last...
Go is easiest if we're talking about pre compiled binaries. If you include builds, dependency hell is real.
C#, JS, and Java have been easy for me. Install JVM/CLR/Node and run one command. Old school Java with EE servers and Tomcat and such was a nightmare but everything I've done recently is self hosting
class Foo
puts "bar"
will just print `bar` when it's parsed.
so something like has_many :baz are just the method call `has_many(:baz)` defined by active record. that creates a few functions using meta-programming. the other thing that ruby uses a lot of are blocks which are just anonymous functions. `do |a,b,c| puts a; end` just a function passed to the method that can be invoked by the function. I think those things are the ones that trip people up the most with when learning.
Not that Ruby = rails
