"You have already activated rake 13.0.1, but your Gemfile requires rake 0.9.6" 😩

Upgraded my Jekyll-based blog from Ruby 1.9.3 to 2.7.0 with just one minor dependency update 😮

If you want OptionParser to parse date arguments, you have to require "optparse/date" 🤨

2.5.1 :001 > a = [1, 2, 3]
=> [1, 2, 3]
2.5.1 :002 > a [2]
=> 3
2.5.1 :003 > a [2] = 4
=> 4
2.5.1 :004 > a[2]
=> 4

Random Ruby performance tip: if you are using anything more complicated than strings/symbols for hash keys, you may want to consider caching their hash values (override the Object#hash method to do so).

I wrote up a blog post about how I found some easily-addressed performance issues in RubyParser: blog.presidentbeef.com/blog/20

Thanks to @zenspider as always for the great gem!

I need to remember this for writing weird Ruby:

def x a
yield a

x -> do
end do |y|
puts y[]

git config --global diff.algorithm patience
