ReadWriteWeb

Earlier this week, we pinged PHP creator Rasmus Lerdorf about the implications of HipHop, the new PHP runtime that Facebook just open-sourced.

Using ReadWriteWeb as an example, he goes into great detail about how speeding up PHP isn't simply a matter of finding a single magic bullet. Lerdorf contends that true optimization comes down to attacking the mundane inefficiencies that sneak into sites of all sizes - even suggesting free tools for PHP devs to use - before a solution such as HipHop is considered.

Last night, we reported that Facebook was planning to release a JIT compiler for PHP, a huge step toward making the PHP runtime - and PHP-based sites and apps - faster by taking the interpreted lagnuage (a.k.a., more human-readable code) a few steps closer to the bare-metal ones and zeros machines actually read.

We've been updated this morning that the PHP runtime has in fact been rewritten, with an extra step: The PHP is translated to C++ (a more machine-readable language) which is then compiled with g++. This project, called HipHop, has been in development under great secrecy at Facebook for the past couple years and has just this morning been open sourced.

The rumors have been flying over what's going on over at Facebook headquarters. The word has been that a PHP team was brought in and made to sign non-disclosure agreements before discussing a PHP project that has been in development for the past two years. Alex Handy, senior editor of the Software Development Times Blog, predicted last Saturday that Facebook "has rewritten the PHP runtime from scratch," and several sources have confirmed for us tonight that Facebook has indeed been making some changes to the basic PHP runtime environment.

According to our sources, Facebook has been working on a PHP compiler that will
increase speed by around 80% and offer a just-in-time (JIT) compilation engine that will offer a number of advantages. The project is very similar to Google's Unladen Swallow project, which rebuilt the Python compiler, boosting the speed fivefold and opening the door for multi-language integration.

You've seen the calls for open identity standards and data portability. Well, Social Beans aims to create standardized "skeleton portability" across social media publishing platforms. What is "skeleton portability"? According to co-founder Emre Sokullu, "Comments, forums, wikis, blogs, rating systems, tagging, sharing and bookmarking are all common social features of today's networking sites". Despite the fact that these are all common denominators of the web, developers continue to hack together their own proprietary implementations. Says Sokullu, "Social Beans aims to standardize a syntax around common social features including users, profiles, avatars, roles and news feeds." For developers, it's a pact for "development portability" or the agreement to follow the same rules for compilers.
