问题 The following is the code I have used for creating a template for a particular page of my website. Since, it's a pre-conference and an independent event, I need to design this page slightly different from what I have used for the home page. So, I have copied the page.php and tried to modify the template. I want: I need to use the PHP code in the page in the WordPress page (because I need to do some query from my database and print it in the current page). The left sidebar should be the

问题 On my Joomla 3.x Bootstrap site I want to have a logo placed overlapping the navbar and slideshow like that: screenshot The navbar is "fixed-top" and the slideshow is placed outside any other container in order to being displayed in full width. To make matters even more complicated, the logo should be fix on top while scrolling just like the navbar. But on a mobile it should move up (again, like the navbar) and be even replaced by another (smaller) image. How could this be achieved? The logo

问题 I am a newbiew to Docker. I am using Mac hence have installed Docker in HortonWorks Sandbox Virtual Box. I am trying to create 2 containers out of a Ubuntu base image. One container runs nodejs on it and other with mysql. I am able to create a container and it lists under Docker ps, but when I try to specify port for that container, it doesn't show me any error, but the port is not getting set. Command used to add port to a running container: docker run -p 8080:8080 nodejsapp where node jsapp

问题 The SSO explanation says the small strings are allocated on heap: OK, but when constructed inside containers, these contents shouldn't be on stack because containers can be created in function and return, while function stack goes stale. So I guess SSO doesn't work with STL containers, does it? 回答1: The difference between "small string" and the "large string" is not the difference between storing it on the stack or on the heap. Instead what differs is the level of indirection . What that

问题 I have an MFC project which, given an initial root path, iterates through every file, folder and subfolder, and subsequently displays each file to the user in a List Control. Since this can easily become a rather lengthy operation, I occasionally yield control to the operating system (via processing a single message pump queue), allowing each of the elements discovered thus far to be displayed. Now here comes the tricky part... I would like to keep the elements sorted by their last known

问题 Hi I am trying to get TensorFlow notebook folder mounted to /src/work folder in Ubuntu. sudo docker run -it -v /src/work:/HOME/notebooks -p 8888:8888 tensorflow/tensorflow:1.3.0 I have tried many combination of -v flags. It is not reading the files already in my work folder or saving new files to it. 回答1: You're mounting the volume incorrectly, precisely the path. It should be -v ~/[absolute path from $HOME]/src/work:~/notebooks/ Explanation: Since your working directory is /notebooks , which

问题 Let's say I have several container classes like these: template<typename T> class Container { /* ... */ }; template<typename T, size_t> class Array : public Container<T> { /* Fixed-sized Container */ }; template<typename T> class Vector : public Container<T> { /* Variable-sized Container */ }; And I have a class which accepts one of these as a template parameter: template<typename T, template<typename> class U, size_t M> class Polygon { U<T> Vertices; // Problem, what if user passes Array (it

问题 I'm implementing a sandboxed JS environment that allows users to upload their JS code and trigger it based on a set of rules. I disabled Java access from Nashorn environment and only allow accessing some utility classes for a few operations such as HTTP requests, base64 encoding etc. Currently, I create ScriptEngine (Nashorn environment) for each JS code uploaded by users but in our environment we have many pre-defined JS code which are used by most of our users. Since creating ScriptEngine

问题 I have the following classes: class Given { public string text = ""; public List<StartCondition> start_conditions = new List<StartCondition>(); }; class StartCondition { public int index = 0; public string device = "unknown"; public string state = "disconnected"; public bool isPass = false; }; I want to convert them into c# properties (using get; and set;) Looking at this question: what-is-the-get-set-syntax-in-c, it seems I can make a property nice and easy like this: class Given { public

问题 I am trying to display some values using MQTT on a PHP based page. The PHP code contains the subscriber. I am using Bluemix IoT service for the MQTT broker. Also, the messages are published via Python code on local machine. When I try to display values on pages using page refresh, the page sometimes fails to display the values. There is no problem at the publisher end as the values are successfully displayed by Bluemix IoT service. My code is as follows: <?php // include class require(
