A CA file has been bootstrapped using certificates from the SystemRoots

the System keychain), place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash

This formula is keg-only, which means it was not symlinked into /usr/local.

Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:

    CPPFLAGS: -I/usr/local/opt/openssl/include

turning off ActiveRecord logging in the console

It’s sometimes quite annoying to have SQL queries clogging up the Rails console when you don’t need to see it. You Can turn it off by setting ActiveRecord’s logger to nil

old_logger = ActiveRecord::Base.logger
ActiveRecord::Base.logger = nil

You can of course turn it back on again.

ActiveRecord::Base.logger = old_logger

since upgrading to macOS Sierra

Of course I need to re-install Command Line Developer Tools without XCode, same after every upgrade.

Robs-MBP:themadkatter rl$ git pull orgin master
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
Robs-MBP:themadkatter rl$ xcode-select --install
xcode-select: note: install requested for command line developer tools

Hooking into ActiveRecord logging

Quick and dirty hook to log long SQL queries and their caller.

ActiveSupport::Notifications.subscribe 'sql.active_record' do |name, start, finish, id, payload|
  time = (finish - start) * 1000
  if payload[:sql] && time > 500
    time = (time * 1000).to_i / 1000.0
    c = caller.select { |l| l =~ /something_(core|music|artists)/ }[0]
    logger = Logger.new(Rails.root.join('log', 'active_record_slow_queries.log'))
    logger.info("(#{time}s) #{payload[:sql]} - #{c}")
  end
end

Comparing plain old Ruby objects

Try Google-ing for <=> it not very helpful. It’s the spaceship method, I can never remember that. So in my case I had a custom classes representing a remote resource and I needed to compare if these objects were similar based on their id. If you compare object == other_object, they won’t be the same because they are different objects in memory. You could write…

class Tentacle
  def ==(other)
    self.id == other.id
  end
end

..but what about >, >=, <, <=, !=, etc. Comparable covers all of this.

class Tentacle
  include Comparable
  def <=>(other)
    self.id <=> other.id
  end
end

…but what if the object you’re comparing against is an instance of another class?

class Tentacle
  def <=>(other)
    return nil unless other.is_a?(self.class)
    self.id <=> other.id
  end
end

And that was the day that was.
