On demand containers

I’ve been interested in Linux Containers for quite a while; I think that they have their sweet spot where they are better than virtual instances — in particular they require less resources.

z-index and events

Today’s lesson has to do with z-index and events. I’d had a png with transparant portions that I wanted to use as a mask, so that information from underneath would not show.

Class is Class, and Instance, Instance, and never the twain shall meet

More about methods, it’s inspired/spurred by a comment on methods, public_methods, and private_methods by Pit Captain.

This is to keep me …

CSS tooltips using CSS Sprites

Thought Bubbles!

For a project I’m currently working on I wanted to make some “bubble” tooltips.  In order to cut down on the size/number of images, I’m using css sprites.  A quick google reveals that nobody else has (at least on the first page) put together tooltips using sprites.  The technique will work with any sort of …

Blogs I’m excited about…

Earlier I was going through rss feeds when I noticed that a blog had been updated. I thought to myself “Oh, cool! they’ve updated.” It struck me that there are certain individual (as in written by an individual) blogs which I follow and am excited when I see posts. Here’s a partial list — bear …

.irbc contents

I think that irb is one of the most useful tools in the rails toolbox. It allows me to quickly determine how something works, sample results (for putting into blogs, don’tcha know) and makes me a more effective ruby developer. One of the nice things about irb is it’s .irbrc file where you can place …
