How to combine two git repositories.

Combining two git repositories

Use case: You have repository A with remote location rA, and repository B (which may or may not have remote location rB). You want to do one of two things:

  • preserve all commits of both repositories, but replace everything from A with the contents of B, and use rA as your remote location
  • actually combine the two repositories, as if they are two branches that you want to merge, using rA as the remote location

NB: Check out git subtree/git submodule and this Stack Overflow question before going through the steps below. This gist is just a record of how I solved this problem on my own one day.

Before starting, make sure your local and remote repositories are up-to-date with all changes you need. The following steps use the general idea of changing the remote origin and renaming the local master branch of one of the repos in order to combine the two master branches.

Survey of screenshot-based CSS testing tools

Currently considering https://github.com/webdriverio/webdrivercss


Core Goals:

  • Can test in up-to-date versions of all major browsers
  • Can test on up-to-date versions of all major OSes
  • Can test in IE9 (because Bootstrap v4 will support IE9+)
  • Don't want to have to setup/maintain our own cluster of VMs running all the necessary OSes (and all the versions of Windows)
  • Workflow for management of reference/baseline/norm screenshots

Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Mastery comes from a combination of at least several of the following:

Folder Structure

Please note

While this gist has been shared and followed for years, I regret not giving more background. It was originally a gist for the engineering org I was in, not a "general suggestion" for any React app.

Typically I avoid folders altogether. Heck, I even avoid new files. If I can build an app with one 2000 line file I will. New files and folders are a pain.

2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

ECMAScript 6 influences

Technologies that influenced ES6 features:

  • Generators: Python
  • Arrow functions: CoffeeScript
  • const: C++ (the latest C standard has borrowed it from C++)
  • let: is old, became popular via BASIC.
    • Also frequently appears in functional programming languages (Lisp, ML, etc.), but creates immutable bindings there.
  • Template literals: E (quasi literals)
  • Destructuring: Lisp (destructuring bind)
  • Modules: CommonJS, AMD
