jq is like sed for JSON data – you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine, and expect it to work.

jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you’d expect.

PostCSS is a tool for transforming CSS with JS plugins. The growing ecosystem of PostCSS plugins can add vendor prefixes, support variables and mixins, transpile future CSS syntax, inline images, and more.

PostCSS is used by Google, Twitter, Alibaba, and Shopify. Its most popular plugin, Autoprefixer, is one of the most universally praised CSS processors available.

PostCSS can do the same work as preprocessors like Sass, Less, and Stylus. But PostCSS is modular, 4-40x faster, and much more powerful.

Supposedly, git-svn can also be used to convert a Subversion repo to Git. Unfortunately, after reading the git-svn docs carefully and several useful resources (like the slightly-obscure Git FAQ, the Git Community Book, Paul Dowman’s blog and Alexis Midon’s blog), it became apparent that all the resources are piecemeal and nothing gives you the BIG HONKIN’ PICTURE. So here it is, ponies and all…

One of the most powerful features of the CSS preprocessor Sass is the mixin, an abstraction of a common pattern into a semantic and reusable chunk. Think of taking the styles for a button and, instead of needing to remember what all of the properties are, having a selector include the styles for the button instead. The button styles are maintained in a single place, making them easy to update and keep consistent.

Type a message into the text box, and the network will try to write it out longhand (this paper explains how it works). Be patient, it can take a while!

Gizoogle was originally created by John Beatty, who started the site in 2005 as a joke after inspiration from a friend's constant use of the slang on America Online's Instant Messenger service and also by Snoop's "Doggy Fizzle Televizzle" program on MTV.
