问题 Since I am asked to develop a web site under company's server, I find it hard to redirect resources to the root of that website. If I use "/" to specify the root directory, all javascripts, images and css files could be used perfectly in localhost. However, if I try to connect to company's server, everything fails since the folder containing all the materials of that web site is only a subdirectory of that server. I tried to use base to link to the root . It works for javascript and images

问题 Suppose I have N M/M/1 queues in parallel where an arriving job is equally likely to join one of the N queues. We want to keep the probability for a job to wait less than 0.2. Given that we have an arrival rate of 400 jobs/second, and a processing times are exponentially distributed with mean 1 second, how many servers would be required? So my take on the question so far is: \lambda = 400 jobs/second \mu = 1 second \rho = (\lambda)/(k\mu) since we want to keep the probability of waiting less

问题 I have a viral image site where people can view funny gifs. A lot of people on reddit are sharing the raw .gif files however, rather than the page with .gif embedded. This is fine - but I'd like to redirect all people viewing raw image .gifs to a handler page called shareraw.php (located in root directory). This handler page will look exactly the same - just with a share link and button to check out the rest of the site. Example of raw image location: http://gifsec.com/wp-content/uploads/GIF

问题 I have successfully installed older versions of gitlab and hosted them at a location like this: mydomain/gitlab with the new version of gitlab doing all of the config though the gitlab-ctl and via me editing the /etc/gitlab/gitlab.rb I'm not sure how to achieve this set-up. I find lots of documentation on stackexchange for older versions of gitlab that did not use gitlab-ctl for configuration but not for the new version. Presently I have gitlab installed and running fine at: mydomain I want

问题 I am having the most frustrating issue with VQmod. I moved my OpenCart store from a Godaddy VPS to Rackspace's Cloud Sites.
