How to make faster scroll effects?

How to make faster scroll effects?

  • Avoid too many reflows (the browser to recalculate everything)
  • Use advanced CSS3 for graphic card rendering
  • Precalculate sizes and positions

Beware of reflows

The reflow appens as many times as there are frames per seconds. It recalculate all positions that change in order to diplay them. Basically, when you scroll you execute a function where you move things between two reflows. But there are functions that triggers reflows such as jQuery offset, scroll... So there are two things to take care about when you dynamically change objects in javascript to avoid too many reflows:

(function() {
// NOTE: I have intentionally avoided the use of jQuery in
// the next two functions so as not to obscure any details.
// Updates the DOM in such a way that layout is constantly
// computed and thrown away.
var UpdateThrash = function(data) {
// Get all the labels
var spans = document.querySelectorAll('.item .lab');
#!/bin/sh
remove_dangling() {
echo "Removing dangling images ..."
docker rmi $(docker images -f dangling=true -q)
}
remove_stopped_containers() {
echo "Removing stopped containers ..."
docker rm $(docker ps -qa)

requiring npm modules in the browser console

demo gif

The final result: require() any module on npm in your browser console with browserify

This article is written to explain how the above gif works in the chrome (and other) browser consoles. A quick disclaimer: this whole thing is a huge hack, it shouldn't be used for anything seriously, and there are probably much better ways of accomplishing the same.

Update: There are much better ways of accomplishing the same, and the script has been updated to use a much simpler method pulling directly from browserify-cdn. See this thread for details: mathisonian/requirify#5

Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.)

git clone --bare [email protected]:usi-systems/easytrace.git
