Programmers: have you tried out Facebook's PHP-to-C compiler?
 

A small group of developers at facebook has programmed a compiler that converts php code into C programs. They named it "Hip Hop" (:1orglaugh) and say it reduces the CPU load by 50%.

Anybody tried it out? Sounds very interesting!

This really wouldn't help the vast majority of php scripts. It's usually unoptimized mysql queries and over-use that causes load problems, not php. The actual PHP on most scripts has negligable impact on cpu usage...

Interesting,this could be used as method of code encoding,since executable code cannot be decoded.

do you believe C++ cannot be decompiled?

Yes,if it compile it into same machine code like ordinary program.

Interesting :-)

That looks really interesting - to be able to run a script as a server daemon certainly has its advantages. Going to check it out on a single index.php file where the index.php is the framework launching block to see if I can get a whole app to run as a daemon.

Good that the source code is also available for inspection.
Better take a look to see if it contains any nasty spying functions. Running an executable from Facebook directly on your server requires some trust. Do you trust Facebook?
