Using Apple’s Aerial Screensavers on Ubuntu After coming across the [Aerial] (https://github.com/JohnCoates/Aerial) screensavers for Mac, and installing them, I decided that I had had enough of the graphics-demos of my Ubuntu Precise system. I hope to provide a simple guide on how to add them to your setup as well.
First, you need to install xscreensaver (for example with aptitude, but your distro should have it):
sudo aptitude install xscreensaver
| { | |
| // Settings | |
| "passfail" : false, // Stop on first error. | |
| "maxerr" : 10000, // Maximum error before stopping. | |
| // Predefined globals whom JSHint will ignore. | |
| "browser" : true, // Standard browser globals e.g. `window`, `document`. | |
| "node" : false, |
| <!DOCTYPE html> | |
| <html> | |
| <!-- NOTES | |
| Demo - uses IOS native scroll available in IOS5, but sidestep the document-bounce behavior. Tested on iPad 1, using IOS 5.1. | |
| This approach uses a set of 3 nested divs. | |
| OuterDiv -- fixed height, width, overflow-scrolling: touch; | |
| MiddleDiv -- fixed height width, overflow-scrolling: touch; fits inside OuterDiv | |
| InnerDiv -- fixed height width, bigger than MiddleDiv, so it kicks in the overflow behavior |
| # Makefile for JS/CSS: | |
| # Uses Closure for JS compiling, YUI for CSS compiling, and JsHint for code quality checking | |
| MAKEFLAGS = --no-print-directory --always-make | |
| MAKE = make $(MAKEFLAGS) | |
| BUILDDIR = ./.build | |
| CLOSUREURL = http://closure-compiler.googlecode.com/files/compiler-latest.zip | |
| CLOSUREDIR = $(BUILDDIR)/closure |
| function getDominantColor(aImg) { | |
| let canvas = document.createElement("canvas"); | |
| canvas.height = aImg.height; | |
| canvas.width = aImg.width; | |
| let context = canvas.getContext("2d"); | |
| context.drawImage(aImg, 0, 0); | |
| // keep track of how many times a color appears in the image | |
| let colorCount = {}; |
