We're doing a small year-end news nerd countdown on Source. Lists are too much, so please send us ONE THING—an app, a tool, an article, a tweet, an image, a map, or something else entirely—that you loved this year. Might be something that made your job easier or made you smarter, or it might have more obscure relevance. All we ask is that you can link to it.
Don't think too hard about it, just take 30 seconds and send one in now to source@mozillafoundation.org. We'll be posting an assembly of favorite things and all we can say about it right now is that there will be GIFs.
Wooo.
It's far from new, but learning Make was huge for me. Mike Bostock's post earlier this year on how and why to use Make changed how I do every project.
