Starting Wordle

Lame attempt at trying to find the best starting word. I found the word list in some blog post. This attempts to find the best starting words by giving each letter in the word score from the percentage of words that share a letter in that position.

The 5 best:

• slate
• sauce
• slice
• shale

Objective-C Coding Convention and Best Practices

Most of these guidelines are to match Apple's documentation and community-accepted best practices. Some are derived some personal preference. This document aims to set a standard way of doing things so everyone can do things the same way. If there is something you are not particularly fond of, it is encouraged to do it anyway to be consistent with everyone else.

This document is mainly targeted toward iOS development, but definitely applies to Mac as well.

Operators

NSString *foo = @"bar";

require 'json'

ACCOUNT_ID = ''

data = JSON.load(File.read('jobs.json'))
data.each do |job|
  unless job[['completed']]
    result = JSON.load(`aws glacier list-jobs --account-id="#{ACCOUNT_ID}" --region="#{job['region']}" --vault-name="#{job['vault']}"`)['JobList'].detect { |i| i['JobId'] == job['job'] }
    job['completed'] = result['Completed']

CFRunLoopSource is cool. It lets you build behavior similar to the mechanisms that drive setNeedsLayout and setNeedsDisplay in UIKit.

I found myself in need of something like this a couple of times. It's great to know that no matter how many times I say I need to update something, I will get a single callback at the end of the run loop that gives me a chance to perform my work.

Here is a little Swift wrapper that makes the API easier to deal with.

Thanks you for your inquiry.

I am only looking for contract work. My rate is one thousand dollars an hour ($1,000/hr). I charge ten thousand dollars ($10,000) for referrals.

If this does not fit the positions you are looking for, please remove me from your list.

Thanks,

Sam
