gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

• ffmpeg
  • macOS: brew install ffmpeg
  • Ubuntu/Debian: apt install ffmpeg

Messing with Maps and ML quickstart

This document: https://goo.gl/AqGoE8

Installation instructions

By far the most annoying part of getting started with messing with ML is installing researcher-made code and turning it into something fun to play with.

Before doing any of these, please install Miniconda. If you don't have it installed already, here's how:

For OSX, this is:

# Install brew
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# Install composer
brew install homebrew/php/composer

### PHPCS
composer global require "squizlabs/php_codesniffer=*"

# Add to your .bash_profile

// think of it outside the context of the router, if you had pluggable
// portions of your `render`, you might do it like this
<App children={{main: <Users/>, sidebar: <UsersSidebar/>}}/>

// So with the router it looks like this:
const routes = (
  <Route component={App}>
    <Route path="groups" components={{main: Groups, sidebar: GroupsSidebar}}/>
    <Route path="users" components={{main: Users, sidebar: UsersSidebar}}>
      <Route path="users/:userId" component={Profile}/>
