You want to use a live wallpaper in x11?
Great!!...but It come as a cost.

I did experiment with .gif backend and non hardware accelerate backend, It sucks.
CPU usage was so high (40% up just for idle), unacceptable for my laptop.

Running with those backend for such a really long time will slowly turn your laptop into the hot potato.
But don't be upset, we can reduce those cost.

Using the video player with hardware video decoding support can reduce the cost.

Stuff I wish I'd known sooner about service workers

I recently had several days of extremely frustrating experiences with service workers. Here are a few things I've since learned which would have made my life much easier but which isn't particularly obvious from most of the blog posts and videos I've seen.

I'll add to this list over time – suggested additions welcome in the comments or via twitter.com/rich_harris.

Use Canary for development instead of Chrome stable

Chrome 51 has some pretty wild behaviour related to console.log in service workers. Canary doesn't, and it has a load of really good service worker related stuff in devtools.

Simple automated GIT Deployment using GIT Hooks

Here are the simple steps needed to create a deployment from your local GIT repository to a server based on this in-depth tutorial.

How it works

You are developing in a working-copy on your local machine, lets say on the master branch. Most of the time, people would push code to a remote server like github.com or gitlab.com and pull or export it to a production server. Or you use a service like deepl.io to act upon a Web-Hook that's triggered that service.
