About Those Lava Lamps
View about_those_lava_lamps.md

Around 2006-2007, it was a bit of a fashion to hook lava lamps up to the build server. Normally, the green lava lamp would be on, but if the build failed, it would turn off and the red lava lamp would turn on.

By coincidence, I've actually met, about that time, (probably) the first person to hook up a lava lamp to a build server. It was Alberto Savoia, who'd founded a testing tools company (that did some very interesting things around generative testing that have basically never been noticed). Alberto had noticed that people did not react with any urgency when the build broke. They'd check in broken code and go off to something else, only reacting to the breakage they'd caused when some other programmer pulled the change and had problems.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Element

Box metrics
  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
  • elem.clientLeft, elem.clientTop, elem.clientWidth, elem.clientHeight
  • elem.getClientRects(), elem.getBoundingClientRect()

JavaScript function hoisting by example

Below are many examples of function hoisting behavior in JavaScript. Ones marked as works successfuly print 'hi!' without errors.

To play around with these examples (recommended) clone them with git and execute them with e.g. node a.js

browserify for webpack users

There's been a strange explosion in misinformation about browserify recently, particularly in comparisons to webpack.

Generally speaking, most of this confusion stems from how webpack is more willing to pull features into its core to ease discoverability while browserify is more likely to push features out to userland instead.

I think that longer-term, separability has more benefits from a maintenance and

introducing ./task.js, THE new javascript task runner automation framework
View dotslashtaskdotjs.markdown

why ./task.js?

One word: task automation. It's basically zero effort and you can use the ./task.js package manager to handle any repetitive tasks. You can use ./task.js to automate everything with minimum effort.

./task.js provides the structure, order, and authority that you as a developer so desperately crave. ./task.js will also take responsibility for your actions if you need it to. It's what everybody is using now. ./task.js is the new hotness. It's all about ./task.js now, just like that.

This is compared to npm run/bash scripts, which are:

Checkout github pull requests locally
View pr.md

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
