Liquid Canvas Version 0.1 Out Now

by | posted in: canvas, html, javascript, round corners | 0

I’ve just released version 0.1 of Liquid Canvas.

It’s a JavaScript library for drawing inside your web page. It works on top of HTML canvas, jQuery and excanvas.

On the Liquid Canvas page you’ll find a demo and an example of how it works.

Here’s just a teaser take from the basic example:

$(window).load(function() {
  $("#example").liquidCanvas(
    "[shadow border gradient] => roundedRect{radius:50}");
});

Yeah, this beast renders rounded corners with a drop shadow! Harrharrharr!!!

timed_fragment_cache on Rails 2.1

by | posted in: cache, fragment caching, rails, ruby | 0

With Rails 2.1 cache_erb_fragment has been replaced by write_fragment. This breaks a plugin I really enjoy to use: timed_fragment_cache by Richard Livsey.

It basically allows you to specify an expiry for the fragments you cache, e.g. inside memcache, by adding a “meta” fragment for the fragment you store containing the expiry time.

Some usage examples – pretty self-explaining:

In your view:

<%- cache 'my_key', 1.hour.from_now do -%>
	...
<%- end -%>

With extensive queries – your view …:

<%- cache 'some_posts' -%>
