Domain Model ORM Adapters
Posted on November 24th, 2009 1 commento I’ve had a series of articles that focus on domain model programming methodologies and most of my examples have demonstrated implementations using the Doctrine ORM (Object Relational Mapper). Given the nature of domain model programming I’ve held to the assertion that models built using this method are truly ORM agnostic and it should be effortless to swap out Doctrine for the ORM of your choice. Well I like to put my money where my mouth is by showing how easily this has been done by showing off adapters that I have written, one for Doctrine, and the other for Zend_Db. The beauty of this system is that both support the same ORM agnostic query syntax demonstrated in my recent post about creating complex sql queries using associative arrays. This means that no modifications are necessary in the models, controllers or views when switching ORMs. Developer’s utopia.

Google lays down the gauntlet with ChromeOS
Posted on November 20th, 2009 No commentsWe all knew it was coming. There were rumors and flat out denials from Google so of course it had to be true. It was the logical path for them and anyone who paid attention to the types of software they’ve been releasing could clearly see the writing on the wall. Every time Google made an announcement or released something new, the was the immediate response… why? Every app, framework, website, tool, they have ever released is a piece of a puzzle that when assembled shows you Google’s over-arching strategy. You just have to step back a little bit to see

Load Your Ads Last
Posted on November 19th, 2009 2 commentsNobody likes ads but we can all agree they are a necessary component of doing business online. I recently had some experience dealing with adify, a aggregating ad platform which pipes in banners from a multitude of sources some with questionable practices in regards to loading performance. I had just launched a beatifully crafted website that employed all the tricks in the book for quick page loads and it was snappy… until we embedded the ad code. I like to load my images asynchronously and I like to execute javascript only once the document has finished loading so imagine the pain of patiently watching little animated gif spinners swirling away for as long as 6-30 seconds because the browser is choking on javascript from the banner ads in the middle of the page. Normally the solution would be to fix the javascript, but being a third party ad network, the embedded code was far beyond my control, so clearly this needed rethinking. I needed to figure out how to load the ads asynchronously as well.

Queued, Concatenated, and Gzipped Assets with the Zend Framework
Posted on November 18th, 2009 2 commentsLinking assets to your templates and layouts is always a mine field. Every person has a different way of doing it and if it is done poorly, it can adversely affect the load time of your website, particularly if you have lots of websites. It’s helpful to understand how the http protocol fetches things like stylesheets and javascript files while it’s loading your page. In order to alleviate traffic for any individual server, a browser is limited to only so many concurrent requests to the same host. I do not recall what that limit is on each browser but I’m sure google does but in any case, if your site is of significant scope, chances are, you are going to need more assets than your browser can pull in at once. If you don’t believe me, install the yslow extension for firefox and run it on a page with many assets and you will see what i’m talking about.
