Today i tried to update a driver for my USB Storage, the installation seems OK, but after it finished, i couldn’t use keyboard/mouse any longer. I know that my new driver has caused the problem.

OV (Organization Validation) – is mostly for corporate , the CA will not only verify you are the owner of the domain, they also ask you some paper to verify your business address.

By default Apache only allows up to 150 connections , if you want more, you need to change the MaxClients parameter in apache.conf or httpd.conf . Apache also limit the max clients to 256 , if you want to override this value, you need to add ServerLimit. Here is an example to increase the max clients to 600. # prefork MPM # StartServers: number of server processes to start # MinSpareServers: minimum number of server processes which are kept spare # MaxSpareServers: maximum number of server processes which are kept spare # MaxClients: maximum number of server processes allowed to start # MaxRequestsPerChild: maximum numberRead More →
