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.

• https://leetcode.com/problems/minimum-size-subarray-sum/

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

def autocomplete
  render :json => autocomplete_for_column(params[:column_name])
end

def autocomplete_for_column(column_name)
  #zipcode and mls num doesnt work
  valid_names = %w(agentlist_fullname officelist_officename officesell_officename schooldistrict)

  if valid_names.include? column_name
    Property.select(column_name).where("#{column_name} LIKE ?", "%#{params[:q]}%").uniq
