#How to install node.js and CouchDB on a Google Compute Engine instance
Make sure you have a Google Compute engine account, have a project created and the gcutil command line tool installed.
Since want to ssh without the gcutil tool, you need to a your ssh key to the instance in addition to the already existing google_compute_engine key (used for gcutil).
lys is a programming language that produces WASM, and its design goal is to be as simple as possible, yet useful to create utilities.
I've been thinking about a subset of JavaScript that could run natively on the browser, similarly to asm.js, but with the ability, through a dedicated parser, to target another language able, on its own, to produce WASM.
The following crazy non sense works already thanks to an agglomerated of modern and deprecated JS features and it might be interesting as experiment to see if a JS to WASM compiler, through the lys indirection, could be possible.
function lys(fn) {

=============================================================== Fully responsive and cross-browser compatible rectangles with slanted edges using pseudo-elements (as supposed to the "skew" transform). In contrast with the skew alternative, the method employed does not cause the rectangles' skewed sides to affect containing elements (such as text), and has minimal impact on surrounding elements in terms of positioning. The code affords full use of other CSS3 styling techniques for additional customization, such as CSS styling, hover states, transitions, etc.
