In Ruby you can call a parent class’s method from another method in a child:

class Parent
def foo
1
end
end

class Child < Parent
def foo
2
end

def bar
Parent.instance_method(
:foo
).bind(self).call - foo
# == -1
end
end

For the new folks on Mastodon, here are the various ways you can discover new people on here to talk to!

Please boost :)

Mike's one piece of advice for new Mastodon users - dive into that Federated column and follow ANYONE and EVERYONE who looks like they've posted anything at all interesting to you. Just hammer the button. There's no penalty for mistakes. Go wild.

Later, when your Home timeline is buzzing, go in and unfollow people you decide you're not enjoying so much now.

Then do that again a few times. Then some more. Forever.

Are there any #Ruby devs from Frankfurt/Darmstadt/Rhein-Main here?

Is there at least one other person interested in toots like https://twitter.com/ruby_frankfurt/status/1189621658350436355 from the local Ruby Meetup?

I've been building Flóðgátt, a replacement streaming API server for Mastodon. The goal is to cut RAM usage and make hosting an instance that much cheaper.

So far, we've cut RAM for the streaming server of an empty instance by ~94.2%

The next task is to make sure that lower RAM usage can scale without other issues (e.g., CPU).

To do that, I need a test server with enough connections to see how Flóðgátt performs under load.

That's where y'all come in: can you please follow @codesections ?

#introduction / #introductions

Hello! I'm a #programmer by trade, and a serial hobbyist. I use #rubyonrails in my side project. I would call it a business, but I've yet to be paid for it. I'm interested in prototyping ideas, and in learning #ruby best practices!

Some of my serial hobbies include singing, playing drums and guitar, drone racing, rock climbing, knitting, dancing at weddings, running, and visiting breweries!

Hey #ruby folk ... I'm trying to trigger an autoscaler for testing purposes. Anybody have a simple cpu-pegging method handy per chance?

has anyone upgraded a rails 5.x app to rails 6 beta?

I thought the javascript assets were going to be required to be moved to webpacker, but it looks like they still work via asset pipeline

is the change that webpack is the default for new apps, but sprockets will continue working for existing apps?

So where does one post Ruby jobs in 2019?

@usmanity you can try out https://exercism.io/tracks/ruby

Question. In which namespace `B` is defined?

```ruby
A = Class.new do
B = 1
end
A::B # => ???
B # => ???
```
