"Push work down the tree"

One disadvantage of the top-down rendering approach we use is that the closer to the root of the application a component lives, the more it will be rerendered. The root component will be rerendered every time any data changes.

This is probably not a big deal for applications without much dynamic state, but let's say you have a input box at the bottom of a large tree of components (which will happen on pretty much any page containing a form). The user types, and every keystroke causes the entire app to rerender!

Well, this might be a big deal, or it might not be, depending on how you design your components. Some general guidelines will help us architect React apps that are fast by default, and don't need a whole lot of manual optimization.

HTML is work, components are placeholders

Dealing with Ruby versions - chruby

Every time I sit down to code, it seems like a new Ruby version is available.

When I first learned ruby I used rvm on my Mac. In production on linux, I use rbenv, likely due to its Capistrano integration.

When I set up my current machine, I found rvm had fallen out of fashion in favour of something called chruby.

The Mediator pattern enables communication (mediation) between views using a mediator object.In the latest version of Backbone, the Backbone object itself can be used as a mediator without the need of a seperate helper.

In the following example, triggerSomething in our ToolbarView uses the global event-bus on the Backbone object to broadcast an application wide event somethingHappened with data.

// First view
var ToolbarView = Backbone.View.extend({
  className: ".toolbar",
  events: {
    "click .button":   "triggerSomething"

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

Ok, I came up with an example.

Programming is like doing a massive sudoku. But you’re not just doing your own square; you have to line up the edges with squares that you’ve already done, or squares other people in your team are working on.

And it’s not just squares that you’ve done — you have to anticipate the sudokus you’ll be doing days, weeks or months from now, and leave easy numbers at the edges so it isn’t impossible to do those squares.

And that’s why some programmers are so engrossed in it, and get all worked up, because they’re like “You left a 5 in the middle of the square, what kind of asshole does that, now I’m gonna have to line all my squares up with that.”

And then someone points out a bug, and you have to trace it back to the square it came from, and then redo that square without screwing up all the other ones.
