the command zig run my_code.zig will compile and immediately run your Zig
program. Each of these cells contains a zig program that you can try to run
(some of them contain compile-time errors that you can comment out to play
with)
The above GIF was rendered with Canvas2D and JavaScript. I used texel, a tool I am developing but have not yet released.
If you want to try this very experimental tool, install the latest working version like so:
npm install texel@1.0.15 --global

| let recorder = new MediaRecorder(stream, options); | |
| let blobs = []; | |

| # Fetch Himawari-8 full disks at a given zoom level. | |
| # Valid zoom levels seem to be powers of 2, 1..16, and 20. |
This project has moved to https://github.com/jonhoo/drwmutex so it can be imported into Go applications.

I've heard a number of people praise the Greiner-Hormann algorithm for clipping arbitrary polygons. They say it has a certain conceptual simplicity and elegance.
@jasondavies is utilizing Greiner-Hormann for D3's polygon clipping operations (2D and spherical). He recently gave a demo of boolean operations on polygons based on as-of-yet unreleased work here.
His earlier clipping demos can be found here and here.
@w8r has a nice, clean implementation of the algorithm for 2D clipping operations with no dependencies. He provides an adapter for clipping polygon regions defin
In all the discussions about ES6 one thing is bugging me. I'm picking one random comment here from this io.js issue but it's something that comes up over and over again:
There's sentiment from one group that Node should have full support for Promises. While at the same time another group wants generator syntax support (e.g.
var f = yield fs.stat(...)).
People keep putting generators, callbacks, co, thunks, control flow libraries, and promises into one bucket. If you read that list and you think "well, they are all kind of doing the same thing", then this is to you.
