Fantasy Premier League daily player statistics dataset

The bulk of the data is a list of player objects under the elements key. Each player object contains detailed information about a player, for example:
This is a follow-up from my previous post about writing a simple backtracking sudoku solver. Recently I generated another puzzle on QQWing which was considered easy: ..6..5....9.1.3..5.....27........9..8...6..7.......1.6..358..2.6....1.5..7...96.1 Number of Givens: 25 Number of Singles: 35 Number of Hidden Singles: 21 Number of Naked Pairs: 0 Number of Hidden Pairs: 0 Number of Pointing Pairs/Triples: 0 Number of Box/Line Intersections: 0 Number of Guesses: 0 Number of Backtracks: 0 Difficulty: Easy And yet my solver takes even longer than it needed on the adversarial input:
As much as I would like to believe that programming has developed my analytical thinking, I am quite terrible at solving sudoku puzzles, so I decided try writing a sudoku solver instead. Here is a simple backtracking solver written in Python 3:
Create data URLs from the command line
Yesterday, I was trying to replace an image on GitHub with another to mockup something by editing its src attribute in the browser inspector, but it didn't work because GitHub has implemented a Content Security Policy (CSP)1 which only allows images from certain sources:
Conditional Git configuration

Namespaced Git clones with git-get

Preventing my Macbook's memory from draining overnight
Twice in the past month, I came back to my (company-issued) MacBook after leaving it with the lid open overnight to find it refusing to start because its battery was completely drained, worrying me a little each time. I wondered why it wasn't going to sleep due to inactivity.
Hot Corners profiles
My company is big on agile, so we're often encouraged to work in pairs. One challenge with pair programming on personal machines is that not everyone might be equally comfortable with the configuration. Ignoring the fact that as a Dvorak keyboard layout user I'm immediately awkward on a teammate's machine, a setting I use on my own machine that my pairs are often not used to is the Hot Corners.
