hosting

问题 I've currently got a ruby on rails app hosted on Heroku that I'm monitoring with New Relic. My app is somewhat laggy when using it, and my New Relic monitor shows me the following: Given that majority of the time is spent in Request Queuing, does this mean my app would scale better if I used an extra worker dynos? Or is this something that I can fix by optimizing my code? Sorry if this is a silly question, but I'm a complete newbie, and appreciate all the help. Thanks! == EDIT == Just wanted

问题 I'm having a weird problem after moving to a new server. A cron to fetch mails checks for authorized IPs, one of which is by default 127.0.0.1 It stopped working after the move, because the REMOTE_ADDR variable isn't populated. It is when called from the browser, but not when ran internally from a cron or from console with php. I dumped the $_SERVER variable and this is all it has from cron/console ( [SHELL] => /bin/sh [MAILTO] => *removed* [USER] => *removed* [PATH] => /usr/bin:/bin [PWD] =>

问题 I have a service application that host several WCF endpoints through different bindings. I want now to host a WCF Data Service in the same service Host. This post makes me believe it's possible. However, every single example on how to create a WCF Data Service creates it from inside an ASP.NET Web project, not a Class Library or Service Application.

问题 I have a host and cPanel access but only one main user and password to cPanel. I want to give someone access to phpMyAdmin but don't want to give that person my main user and password for cPanel. Is there anyway to give someone access to phpMyAdmin but not cPanel? 回答1: The phpMyAdmin which comes with cPanel (in the 3rdparty-directory) is apparently secured with the cpanel-authentication, so the answer is "no". You could install your own phpMyAdmin (maybe it's even available in the script

问题 I purchased a very well-known 3rd-party php-based forum software. Uploaded to my server, run it for few weeks. This morning, when I visit my site, it display all the PHP code, including all the comments etc, like what you will see if you open it with notepad. It was very scary, my database config which is in PHP file also visible, what happened? I have no choice but to take my website down now. What should I do? How can view PHP code? I thought PHP code is very safe? Has somebody hacked my

问题 I have very unusual problem. I've created an HTML form with all types of inputs. Then I put it on a server and what happened took me to the ground literally. All my checkboxes turned into textboxes. The code I put on my website has checkboxes in it, but when I use firebug it says it has textboxes there. -HTML code is valid: <input name="ksh" type="checkbox" id="ksh" /> I tried on a different server, it works fine there, so I assume it's a server-based problem. But I have no idea what can
