Nine Tesla employees stormed Seattle last weekend on a four-day sales and marketing blitz. The trip was a great success – not only for 80 customers and media who got to drive the car but for those of us at Tesla scouting the perfect location for a Seattle-area store, which we are planning to open [...]

The California Air Resources Board (CARB) is considering changes to the Zero Emission Vehicle Program (also commonly known as the “ZEV Mandate”). If you’ve seen Who Killed the Electric Car? you have an idea of what the ZEV Mandate is and how its implementation has been challenged and impeded by traditional auto manufacturers for more [...]

The global economy is losing more money from the disappearance of forests than through the current banking crisis, according to an EU-commissioned study.

The Bush administration has balked at declaring greenhouse gases a pollutant, but several state courts - Kansas, Colorado, Georgia and now Utah -- have tackled the relationship between coal-fired plants and climate change, with mixed results.

A new epoch is beginning at the top of the Earth, where the historic melting of the vast Arctic ice cap is opening a forbidding, beautiful, and neglected swath of the planet.

Elizabeth Smith has a new blog post today showing the steps you'll need to get code coverage testing up and running on your Windows extensions.

She spells out a seven step process that involves Microsoft Visual Studio (with Code Coverage support), a properly compiled PHP instance and a little familiarity with the Windows command line to get things working.

As you can see, this could be a nice automated task. Figuring out this path to madness took a lot of googling to find some information about running code coverage from the command line.

She also includes a tip on getting the .NET parts to play nice with Visual Studio.

Keith Casey has written up somewhat of a preview of things to come at this year's PHP Appalachia:

PHP Appalachia originally came about a few years back because... well, I'm not sure, but I've heard (I wasn't there) that it resulted in a bunch of PHP geeks sitting around a camp fire, a bit hacking away a bit during the day, and generally building the community that PHP is known for.

He mentions other community members that'll be attending including Elizabeth Naramore, Ben Ramsey and Cal Evans for the four day long event.

Following up on their introduction to design patterns, the PHP Freaks have posted tutorials covering three of the more popular patterns - strategy/bridge, value object and singleton.

• Strategy and Bridge - The Strategy and Bridge patterns provide solutions to apply polymorphism in more flexible way than you can accomplish with only inheritance.
• Value Object - The Value Object pattern has, just like the Singleton, to do with referencing and instances. In a way, the Value Object is the opposite of the Singleton: it's goal is to ensure NOT to use the same instance, under certain conditions.
• Singleton and Singleton Registry - The Singleton pattern ensures that you are always dealing with the same, single instance, wherever in your application. The Registry pattern usually utilizes the Singleton pattern (hence "Singleton Registry") to make the same 'globalness' apply to objects who's classes weren't necessarily designed to
