Five common PHP design patterns
Editor's note : See the follow-up article " Five more PHP design patterns " to learn about five additional design patterns that you might find useful. Design patterns were introduced to the software community in Design Patterns , by Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides (colloquially known as the "gang of four"). The core concept behind design patterns, presented in the introduction, was simple. Over their years of developing software, Gamma et al found certain patterns of solid design emerging, just as architects designing houses and buildings can develop templates for where a bathroom should be located or how a kitchen should be configured. Having those templates, or design patterns , means they can design better buildings more quickly.

Flash’s Future Fades as Windows Close on Adobe | Gadget Lab
The future of Flash looks dimmer and dimmer as another major player in the mobile space shuns support of the platform. Microsoft’s brand new Windows 8 Metro user interface will not support Adobe Flash or other plug-ins, instead embracing the HTML5 set of web standards, according to Microsoft’s Internet Explorer team leader Dean Hachamovitch. For users who access legacy ActiveX controls, they’ll have to jump out of the Metro UI and switch to the classic-styled desktop browser. Hachamovitch explains that running IE without Flash or other plug-ins “improves battery life as well as security, reliability, and privacy for consumers.” These are pretty much the same reasons that Apple doesn’t support Flash on its devices. “Providing compatibility with legacy plug-in technologies would detract from, rather than improve, the consumer experience of browsing in the Metro style UI ,” Hachamovitch wrote in a blog post on Thursday.
