The Ray Tracing in One Weekend series of books are now available to the public for free online. They are now released under the CC0 license. This means that they are as close to public domain as we can get. (While that also frees you from the requirement of providing attribution, it would help the overall project if you could point back to this web site as a service to other users.) These books are formatted for printing directly from your browser, where you can also (on most browsers) save them as PDF. In Ray Tracing in One Weekend, you will build a simple brute-force path tracer. Continuing with Ray Tracing: The Next Week, you will add textures, volumes (like fog), rectangles, instances, lights, and support for lots of objects using a bounding volume hierarchy (BVH). Finally, with Ray Tracing: The Rest Of Your Life, we'll dive into the math of creating a very serious ray tracer.

The first truly secure and intuitive templates for PHP. The most common critical vulnerability in websites is Cross-Site Scripting (XSS). It allows an attacker to insert a malicious script into a page that executes in the browser of an unsuspecting user. It can modify the page, obtain sensitive information or even steal the user's identity. Templating systems fail to defend against XSS. Latte is the only system with an effective defense, thanks to context-sensitive escaping. Latte is based on PHP, whereas Twig is based on Python. A designer in Latte doesn't have to constantly switch between two different conventions. Stay in touch. The plugin for Tracy informs you on each page which templates and which variables are being rendered. Latte has native support in NetBeans and an excellent plugin for PhpStorm that suggests tags, filters and PHP code. Latte is a next generation templating system – it understands HTML.
