Go Pipelines

This document demonstrates a basic pipeline in Go and talks about a risk in in implementing them. Keep in mind that:

• Using FizzBuzz here is contrived, but quite a nice way to demonstrate the concept. Obviously there is no advantage to running the basic workload of FizzBuzz in a Goroutine, but if the task involved heavy computation or long lived I/O, it starts to make a lot more sense.
• The problem discussed only applies to Goroutines that actually need to have a way to

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.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Getting the code

git clone https://gist.github.com/6780d7cc0cabb1b4d6c8.git

Executing the code

$ npm install # maybe npm start will take care of it but just in case
$ npm start && open out.png

nix-shell and Shebang Lines

A few days ago, version 1.9 of the Nix package manager was released. From the release notes:

nix-shell can now be used as a #!-interpreter. This allows you to write scripts that dynamically fetch their own dependencies.

Trello CSS Guide

“I perfectly understand our CSS. I never have any issues with cascading rules. I never have to use !important or inline styles. Even though somebody else wrote this bit of CSS, I know exactly how it works and how to extend it. Fixes are easy! I have a hard time breaking our CSS. I know exactly where to put new CSS. We use all of our CSS and it’s pretty small overall. When I delete a template, I know the exact corresponding CSS file and I can delete it all at once. Nothing gets left behind.”

You often hear updog saying stuff like this. Who’s updog? Not much, who is up with you?
