TLDR

Step 1 - Create a New SSH Key

We need to generate a unique SSH key for our second GitHub account.

ssh-keygen -t rsa -C "your-email-address"

Be careful that you don't over-write your existing key for your personal account. Instead, when prompted, save the file as id_rsa_COMPANY. In my case, I've saved the file to ~/.ssh/id_rsa_work.

Step 2 - Attach the New Key

Avoiding Hash Lookups in a Ruby Implementation

I had an interesting realization tonight: I'm terrified of hash tables. Specifically, my work on JRuby (and even more directly, my work optimizing JRuby) has made me terrified to ever consider using a hash table in the hot path of any program or piece of code if there's any possibility of eliminating it. And what I've learned over the years is that the vast majority of execution-related (as opposed to data-related, purely dynamic-sourced lookup tables) hash tables are totally unnecessary. Some background might be interesting here.

-# Usage:
-# $ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Templates
-# $ bash ~/remove-boilerplate-comments-from-xcode-templates.sh
-# Repeat for /Applications/Xcode.app/Contents/Developer/Library/Xcode/Templates
-find -E . -type f \
-    \( -regex '.*\.[chm]' -or -regex '.*\.swift' \) \
-    -exec sed -i '' '1,/^$/d' '{}' ';'
