That kind man can send me a copy of the Auth and ACLs on the Zend Framework in the practice project. Now we are studying ZF. There are two open-source blogs on the web that look at the code. Not too hard. There is no example where the key is. As I said above. Authentication and access control. I've studied thinkphp.

with the hardware platform. A constant Hz is defined in the system, representing the number of minimum time intervals per second. In this way, the unit of jiffies is 1/Hz. Jiffies of Intel Platform is measured in 1/100 seconds, which is the minimum time interval that the system can distinguish. For each CPU time slice, jiffies must be added with 1. CPU utilization is expressed by dividing the execution user State + system state jiffies by the total jifffies. In Linux, you can use the/proc/
