Not entirely sure what's going on here, but I can't seem to call the EM.synchrony block without it crashing.
I'm using EM-Synchrony version 1.0.0 with EM-Http-Request version 1.0.0, and EventMachine version 1.0.0.beta.4. I'm attempting to run it on a Mac (Lion) using RVM and Ruby 1.9.2p290. Here's the backtrace from the segfault:
ruby-1.9.2-p290 :003 > EM.synchrony {}

Any ideas?
Filed an issue on the EM-Synchrony GH repo. Igrigorik responded that it's a known bug with 1.9.2. Upgrading to 1.9.3 fixed this for me.

I am using a MacBook Pro with M1 Pro. Ruby has been installed via Homebrew and always worked fine on my Intel-MacBook. Does somebody know this error?
Regards,
Yannick
The issue was the following: I installed Ruby with Homebrew, but macOS ships its own Ruby, but in the wrong version. I followed this tutorial and that solved my problem.
I think it's an issue specific to M1 MacBooks, You can try
arch -arch x86_64 bundle install
arch -arch x86_64 bundle exec jekyll serve
Although I believe it's not an "ideal fix". Solution suggested by #Yannick seems promising, but I haven't tried it.
I am not doing anything fancy here; nothing. As a noob, could someone explain to me why this is happening? I am following this tutorial and I got the error:
Rails Console:
require 'bigdecimal' #=> false
sum = BigDecimal.new("0") #=> stack level too deep
So I thought, let me install BigDecimal and all would be ok. No. Same issue. Is this an issue with ruby 2.3.1p112? Does it has any affiliation with Rails 5 that Im using? Im in the console, not Rails. Thanks.
Stack Trace:
irb(main):001:0> BigDecimal.new("2.11")

I'm trying to monkey patch Object and while my tests run fine,
I can't load my project with Pry anymore.
Here is the relevant code:
module CoreExtensions
def instance_values
instance_variables.each_with_object({}) do |var, hash|
hash[var[1..-1]] = instance_variable_get(var)
end
end
def ==(other)
(self.class == other.class) &&
(instance_values.equal? other.instance_values)
end
end
Object.include CoreExtensions
Using
pry -r ./core_extentions.rb
leads to this stacktrace:
Error: No live threads left. Deadlock?

The same thing happens when I include my CoreExtentions in the main class.
I read about Pry's input_lock, but I don't understand what produces the deadlock.
Does anyone have an idea why this is happening?
You have redefined method == for all objects, which is not a good thing.
This comes about from the last line in your question, namely Object.include CoreExtentions
Without that definition, it loads fine.
I'd like to programmatically parse an .scss file to generate a flat list of selectors that are used in that file, mostly as basis for some static code analysis.
In SASS terms, I'm looking for a way to get a list of all Sass::Tree::RuleNode for a given .scss file.
So far I'm using Sass::Engine.for_file to create a Tree. Then, in order to use Sass::Tree::RuleNode.resolved_rules on the individual Nodes I have to use Tree::Visitors::Cssize, according to the documentation. But somewhere in there is a (probably simple) error.
require 'sass'
sass_engine = Sass::Engine.for_file('files/examples.scss',{
:style => :compact,
:load_paths => ['files'],
:syntax => :scss,
})
tree = sass_engine.to_tree
Sass::Tree::Visitors::Cssize.visit(tree)
tree.each do |node|
if node.is_a? Sass::Tree::RuleNode
puts node.resolved_rules
end
end
This is the error and stacktrace I'm getting:

Thanks a lot in advance.
I'm not overly familiar with the Sass gem codebase but was able to get this working (without crashing, at least) by following the code example of the Cssize class from sass gem's sass/tree/root_node.rb file, which has:
# Runs the dynamic Sass code *and* computes the CSS for the tree.
# #see #to_s
def render
Visitors::CheckNesting.visit(self)
result = Visitors::Perform.visit(self)
Visitors::CheckNesting.visit(result) # Check again to validate mixins
result, extends = Visitors::Cssize.visit(result)
Visitors::Extend.visit(result, extends)
result.to_s
end
Taking this code snippet and applying it to your script, I get:
#!/usr/bin/env ruby
require 'sass'
sass_engine = Sass::Engine.for_file('files/examples.scss',{
:style => :compact,
:load_paths => ['files'],
:syntax => :scss,
})
tree = sass_engine.to_tree
Sass::Tree::Visitors::CheckNesting.visit(tree)
result = Sass::Tree::Visitors::Perform.visit(tree)
Sass::Tree::Visitors::CheckNesting.visit(result)
result, extends = Sass::Tree::Visitors::Cssize.visit(result)
Sass::Tree::Visitors::Extend.visit(result, extends)
result.each do |node|
if node.is_a? Sass::Tree::RuleNode
puts node.resolved_rules
end
end
I have a Ruby 1.9.2-p290 program which is using the pivotal-tracker gem. The configuration of the application environment is using RVM. When I execute this on one machine the application works as expected yet on a different machine it results in the error below.
To simplify the problem I made a new ruby file with only the following contents and still receive the error:
require 'pivotal-tracker'
puts 'hello'
Given this works on one machine and not another I assume there is a configuration difference of some sort between the two.
What is the best way to debug what is going on to cause this error?
Thank you in advance!

It looks like libxml-ruby is the part that is segfaulting. I've had this before when system libraries have been updated possibly by:
System update (e.g. Snow Leopard to Lion)
Package updates (e.g. Homebrew, or Macports)
libxml-ruby is compiled against a specific version of the library libxml2, if the library is then updated it will sometimes work for a bit, but generally be unstable (like this). You could try and force it to recompile by doing something like:
$ gem uninstall libxml-ruby
$ gem install pivotal-tracker
