--- Day 5: Binary Boarding --- You board your plane only to discover a new problem: you dropped your boarding pass! You aren't sure which seat is yours, and all of the flight attendants are busy with the flood of people that suddenly made it through passport control.

You write a quick program to use your phone's camera to scan all of the nearby boarding passes (your puzzle input); perhaps you can find your seat through process of elimination.

Instead of zones or groups, this airline uses binary space partitioning to seat people. A seat might be specified like FBFBBFFRLR, where F means "front", B means "back", L means "left", and R means "right".

The first 7 characters will either be F or B; these specify exactly one of the 128 rows on the plane (numbered 0 through 127). Each letter tells you which half of a region the given seat is in. Start with the whole list of rows; the first letter indicates whether the seat is in the front (0 through 63) or the back (64 through 127). The next letter indicates which h

How to install the GitHub CLI without Homebrew
echo "This will install the GitHub CLI (gh) onto your system"
echo "When this is done, you'll have a new 'gh' command line tool..."

echo "That directory will be in your 'PATH' environment variable..."

Vecty/GopherJS Web App Framework

Web App Framework with Vecty & GopherJS

This document describes a web app framework targeted for Vecty & GopherJS.


  • Go is the primary language for all frontend and backend tasks. An app developer should be able to write full-feaured web applications using only Go and without any HTML/Javascript/CSS knowledge or expertise
  • The framework handles and compiles Go code targeting the frontend and backend
    • Framework can build frontend code into HTMl/JS/CSS or Web Assembly (WASM). In both cases, the resulting app is a SPA
  • Framework design might enable classic web apps with multiple routes, but that's not a design goal
