Facebook’s HipHop Engine, When to Use it, and Getting it to Work with CodeIgniter
HipHop for PHP (shortened as HipHop) describes a series of PHP execution engines and improvements created by Facebook. The original motivation of HipHop was to save resources on Facebook servers, given the large PHP codebase of facebook.com. As development of HipHop progressed, it was realized that HipHop could substantially increase the speed of PHP applications in general. Increases in web page generation throughput by factors of up to 6 have been observed over Zend PHP.
Setup a test environment for HipHop VM.
The final VM will contain HHVM, Nginx, PHP, MySQL, ab.
Some graphs comparing PHP 5.3, PHP 5.5 and HHVM.

# This number should be, at maximum, the number of CPU cores on your system. # (since nginx doesn't benefit from more than one worker per CPU.)
“My understanding is that in order to maximize nginx performance you normally set the number of worker_processes equal to the number of core/cpu’s”

I’m preforming some benchmark tests on avconv in two different machines..
One is a cloud hosting plan, with a SSD disk and 512Mb of RAM, running Ubuntu 13.
I was having some troubles trying to make the first login on my Ubuntu Server…
No root, no root password… even the username that i’v created while setting it up wasn’t working… eventually after some 20 times trying it worked….. funny!
Root Password for Ubuntu Fresh Installation? There isn’t.
sudo
is the solution.

Amount of memory limited to 256MB – Strike F1 Key to continue / F2 to run the setup utility
WTF?
I was getting somehow alarmed with that error…. but I’v realized that it started to appear after I had enable OS Install Mode on bios… so, went there and disabled it.
