GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window

because this is a gist from 2011 that people stumble into and maybe you should AES instead of 3DES in the year of our lord 2019.

packagingExcludes configuration tag can be used to exclude certain files or directories from the war file. It is important to put '/' character at the end of the directory to be excluded. If there is no such '/' character, then the entry is interpreted as a regular file.

Setup macOS

I'm in a hospital in Spain and my MacBook was stolen.

Now I bought a new one and need to configure it. I have an AirPort Time Capsule that backs up everything using Time Machine, but I don't want all the crap I had in the old one. So let's get our hands dirty!

1. Update OS to latest version

# 0 is too far from ` ;)
set -g base-index 1

# Automatically set window title
set-window-option -g automatic-rename on
set-option -g set-titles on

#set -g default-terminal screen-256color
set -g status-keys vi
set -g history-limit 10000
