Converting an SVG animation to a video with the MediaRecorder API and a hidden canvas.
Drawing frames from img elements can introduce an extra delay, so this version generates all the frames upfront and then renders them in a loop with requestAnimationFrame().

If you're trying to run imagemin (from grunt or gulp or anything else) on Alpine, you certainly had to meet this error :
Error: spawn /YOUR_PROJECT_PATH/node_modules/jpegtran-bin/vendor/jpegtran ENOENT
or the same with optipng or gifsicle instead of jpegtran.
Here's how to solve it.
First you need to install on Alpine missing package used to compile jpegtran, gifsicle and optipng binaries. Those packages are (at least):
autoconf automake file build-base nasm musl libpng-dev zlib-dev

Things I had to do using Homebrew to get my local web dev environment back up and running after migration to OSX Sierra + Xcode 8.1.
Note: I used brew reinstall because I had already installed most of this previously under Yosemite. Probably better ways to do this, but this is what worked for me.
brew doctor
brew tap homebrew/dupes
brew tap homebrew/versions

How to use:
download.sh file and put it into a directory where you want the files to be saved.cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

If you're doing stuff with Ruby on a Mac, e.g. installling Jekyll or something, by default you'll end up having to use the sudo command to do stuff, since the permission to modify the default config is not available to your user account.
This sucks and should be avoided. Here's how to fix that.
To make this better, we are going install a new, custom Ruby. This used to be a big, scary thing, but thanks to the awesome tools Homebrew and rbenv, it's a snap.*
A word of warning: you will have to use Terminal to install this stuff. If you are uncomfortable with text, words, and doing stuff with your computer beyond pointing and hoping, this may not work well for you. But if that's the case, I'm not sure why you were trying to use Ruby in the first place.
