Today I gave a keynote at ACCU in Oxford.  In the midst of it I made two (count them) two statements that I should have known better than to make.  I was describing the late '70s, and the way we felt about the C language at the time.  My slide said something like: "C was for real men."  Emily Bache, whom I know and hold in high regard, spoke up and said "What about women?".  And I said something like: "We didn't allow women in those days."  It was a dumb crack, and should either not have been said, or should have been followed up with a statement to the effect that that was wrong headed.  

The second mistake I made was while describing Cobol. I mentioned Adm. Grace Hopper.  I said something like "May she rest in peace."  I don't know that any of the words were actually demeaning, but the tone was not as respectful as it should have been to an Admiral in the United State Navy, and one who was so instrumental in our industry; despite what I feel about Cobol.  

I am a 59 year old programmer who was brought up

There are three easy to make mistakes in go. I present them here in the way they are often found in the wild, not in the way that is easiest to understand.

All three of these mistakes have been made in Kubernetes code, getting past code review at least once each that I know of.

1. Loop variables are scoped outside the loop.

What do these lines do? Make predictions and then scroll down.

func print(pi *int) { fmt.Println(*pi) }

This was my solution for a polymorphic many-to-many association

class ItemCountry < ActiveRecord::Base
  belongs_to :locatable, :polymorphic => true
  belongs_to :country
  # fields are :locatable_id, :locatable_type, :country_id
end

class Title < ActiveRecord::Base

has_many :countries, :through => :item_countries, :as => :locatable

Hi everyone, I'm Chris Wanstrath.

When Jeremy asked me to come talk, I said yes.  Hell yes.  Immediately.  But
then I took a few moments and thought, Wait, why?  Why me?  What am I supposed
to say that's interesting?  Something about Ruby, perhaps.  Maybe the
future of it.  The future of something, at least.  That sounds
keynote-y.
