So two things have been bugging me off late, knowing if the previous command exited non-zero, and I’ve just now once too many times committed on the wrong git branch.

Using php-fpm and mod_proxy_fcgi to optimize and secure LAMP servers
Wednesday, January 16th, 2013So up until now I’ve been using mpm_itk or mpm_peruser – both with advantages and disadvantages in an attempt to secure web content.

Personally I prefer mpm_worker (or more recently mpm_event) since it’s threaded, and I find that it uses less resources (in terms of memory mostly). A lot of movement has also been happening with respect to FastCGI and the advantages are very good, both in terms of security and reliability (in theory).
