  • Creating dynamic resource in cookbook

    - by zsong
    Long story short, here is my code: template "...." do .... notifies :restart,"service[myservice_One]" notifies :restart,"service[myservice_Two]" end ['One', 'Two'].each do |proj| service 'myservice_#{proj}' do start_command "setsid /etc/init.d/my_command #{proj} start" stop_command "setsid /etc/init.d/my_command #{proj} stop" restart_command "setsid /etc/init.d/my_command #{proj} restart" status_command "setsid /etc/init.d/my_command #{proj} status" supports :status => true, :restart => true action [:enable,:start] end end I got this error: template[...] is configured to notify resource service[celery_worker_One] with action restart, but service[celery_worker_One] cannot be found in the resource collection. I know I can duplicate my code to make it work but how to dynamically create the services? Thanks!

  • Dynamic Button Layout without hard coding positions

    - by mmc
    I would like to implement a view (it will actually be going into the footer of a UITableView) that implements 1-3 buttons. I would like the layout of these buttons (and the size of the buttons themselves) to change depending on which ones are showing. An example of almost the exact behavior I would want is at the bottom of the Info screen in the Contacts application when you are looking at a specific contact ("Add to Favorites" disappears when it is clicked, and the other buttons expand to take up the available space in a nice animation). As I'm running through the different layout scenarios, I'm hard coding all these values and I just think... "this is NOT the way I'm supposed to be doing this." It even APPEARS that Interface Builder has some features that may do this for me in the ruler tab, but I'll be darned if I can figure out how they work (if they work) on the phone. Does anyone have any suggestions, or a tutorial online that I could look at to point me in the right direction? Thanks much.

  • repeat text animation, as3

    - by pixelGreaser
    Hi, My text animation works perfectly, but doesn't repeat. How do I get this to repeat? Sorry I don't know Flash that well, but I just want this to play over and over. Thanks. var myArray:Array = ["Big", "Holiday", "Sale", "Buy", "Now", "And", "Save"]; Timer var tm:Timer = new Timer(500,0); tm.addEventListener(TimerEvent.TIMER, countdown); function countdown(event:TimerEvent) { if (myArray.length>0){ tx.text = myArray.shift(); } } tm.start(); I tried this if (++myArray.length % 10 == 0)

  • Need to dynamically-generate a "sticky note" text

    - by gravyface
    Working on a website that has an image of a sticky note which will change text somewhat frequently (every month or so) as new "todo" items are created on it. Font I'm currently using is not Web Safe and the text is slightly angled to match the skew of the sticky note as well. Now I'm a pragmatist, and in situations like this I would normally secede defeat and opt for something more CSS/HTML practical. But no more! I'm falling a bit behind on what's going on with HTML5, CSS3, PNG graphics, Flash (ugh), and/or any other rich visuals. I'm decent with PHP/CSS/JS (jquery), have dabbled in Flash/actionscript too. My question is: what tools/method should I be looking at here?

  • Apache Modrewrite & 301 redirect- Dynamic URLs with characters.

    - by Ben Chesters
    I've been trying for weeks, literally, to rename these URLs and also ensure the old one is 301 redirected to the new one: www.example.com/?mod=11&p=215 - www.example.com/clean-url-section www.example.com/?mod=96&tab=6 - www.example.com/clean-url-section-2 Does anyone have any idea why I am having no luck, I got 500 server errors or nothing at all! Is it because of the question marks and characters? I'd be grateful for any help. I have tried this (below) and it seems to be redirecting to the http:// www.example.com/new-page (this page doesn't exist, as I only want it to rename the page BUT use a 301 so that search engines continue you to value it) RewriteCond %{query_string} mod=96&tab=6 RewriteRule (.*) http:// www. example.com/new-page? [R=301,L] Scratching my head!

  • Dynamic loaded libraries and shared global symbols

    - by phlipsy
    Since I observed some strange behavior of global variables in my dynamically loaded libraries, I wrote the following test. At first we need a statically linked library: The header test.hpp #ifndef __BASE_HPP #define __BASE_HPP #include <iostream> class test { private: int value; public: test(int value) : value(value) { std::cout << "test::test(int) : value = " << value << std::endl; } ~test() { std::cout << "test::~test() : value = " << value << std::endl; } int get_value() const { return value; } void set_value(int new_value) { value = new_value; } }; extern test global_test; #endif // __BASE_HPP and the source test.cpp #include "base.hpp" test global_test = test(1); Then I wrote a dynamically loaded library: library.cpp #include "base.hpp" extern "C" { test* get_global_test() { return &global_test; } } and a client program loading this library: client.cpp #include <iostream> #include <dlfcn.h> #include "base.hpp" typedef test* get_global_test_t(); int main() { global_test.set_value(2); // global_test from libbase.a std::cout << "client: " << global_test.get_value() << std::endl; void* handle = dlopen("./liblibrary.so", RTLD_LAZY); if (handle == NULL) { std::cout << dlerror() << std::endl; return 1; } get_global_test_t* get_global_test = NULL; void* func = dlsym(handle, "get_global_test"); if (func == NULL) { std::cout << dlerror() << std::endl; return 1; } else get_global_test = reinterpret_cast<get_global_test_t*>(func); test* t = get_global_test(); // global_test from liblibrary.so std::cout << "liblibrary.so: " << t->get_value() << std::endl; std::cout << "client: " << global_test.get_value() << std::endl; dlclose(handle); return 0; } Now I compile the statically loaded library with g++ -Wall -g -c base.cpp ar rcs libbase.a base.o the dynamically loaded library g++ -Wall -g -fPIC -shared library.cpp libbase.a -o liblibrary.so and the client g++ -Wall -g -ldl client.cpp libbase.a -o client Now I observe: The client and the dynamically loaded library possess a different version of the variable global_test. But in my project I'm using cmake. The build script looks like this: CMAKE_MINIMUM_REQUIRED(VERSION 2.6) PROJECT(globaltest) ADD_LIBRARY(base STATIC base.cpp) ADD_LIBRARY(library MODULE library.cpp) TARGET_LINK_LIBRARIES(library base) ADD_EXECUTABLE(client client.cpp) TARGET_LINK_LIBRARIES(client base dl) analyzing the created makefiles I found that cmake builds the client with g++ -Wall -g -ldl -rdynamic client.cpp libbase.a -o client This ends up in a slightly different but fatal behavior: The global_test of the client and the dynamically loaded library are the same but will be destroyed two times at the end of the program. Am I using cmake in a wrong way? Is it possible that the client and the dynamically loaded library use the same global_test but without this double destruction problem?

  • Dynamic, reflective SignalHandler in Java

    - by pilcrow
    How do I install signal handling logic iff sun.misc.Signal is available? Background First generation of my code looked something like this: class MyApp { public static void main(String[] args) { ... Signal.handle(term_sig, new SignalHandler() { public void handle(Signal sig) { ... } }); ... } } I believe I understand how to reflectively test for and use signal handlers -- Class.forName("sun.misc.Signal"), reflectively call Signal.handle, and so forth. My impulse was simply to instantiate another anonymous inner class with the dynamically obtained SignalHandler class, but I think that's just wishful syntax.

  • how to do server side form validation for dynamic inputs with Django

    - by Satoru.Logic
    Hi, all. I am using django.forms.Form to validate form data in a survey applications. In a survey-creating form, a user can submit multiple questions that belong to the survey being created. Names for the question inputs are in the form of 'question_seq' , where seq is maintained using Javascript. Back in the server side, my code doesn't know before hand how many such questions will be submitted. Is there any way to do this with Django form so that the form can automatically recognizes the questions and validate them?

    Hi All, I have a specific requirement of extracting text and images from a specific area in a pdf file.The area might be a selected or highlighted or from a given set of coordinates. When i went through, all the approaches are to extract images and text entirely from the PDF on not in a specified location. I tried with iTextSharp,Syncfussion,Apose but couldn figure out a better approach for this. If somebody could help me out in this it would be greatfull. Can you share your ideas and suggestion on how to implement this in .net. Regards, Arun.M

    I see this a lot now, jpg files displaying your IP address. To you of course, not to others, they would see their own For example: How is this even possible? If this is possible, would it be possible to log an IP into a MySQL database from the picture as well? Is my IP getting logged when I view this?

  • C++ Dynamic Allocation Mismatch: Is this problematic?

    - by acanaday
    I have been assigned to work on some legacy C++ code in MFC. One of the things I am finding all over the place are allocations like the following: struct Point { float x,y,z; }; ... void someFunc( void ) { int numPoints = ...; Point* pArray = (Point*)new BYTE[ numPoints * sizeof(Point) ]; ... //do some stuff with points ... delete [] pArray; } I realize that this code is atrociously wrong on so many levels (C-style cast, using new like malloc, confusing, etc). I also realize that if Point had defined a constructor it would not be called and weird things would happen at delete [] if a destructor had been defined. Question: I am in the process of fixing these occurrences wherever they appear as a matter of course. However, I have never seen anything like this before and it has got me wondering. Does this code have the potential to cause memory leaks/corruption as it stands currently (no constructor/destructor, but with pointer type mismatch) or is it safe as long as the array just contains structs/primitive types?

  • JS DOM: Get elements by text content.

    - by hristo
    Hello! I am looking for a way to perform fulltext search on the DOM tree with JS. In two words, I would like to retrieve the list of text nodes which contain a given string. I've tried mootools' Element.getElements ( ':contains[string]' ) but I can't get it to work with strings containing whitespace. I'm thinking about simply indexing all text nodes and checking against each node for the string being searched for, but, in my project, there's no way of telling when the DOM updates in order to maintain such an index up-to-date. Any better ideas? Thanks

  • how to add a dynamic param

    - by user569846
    the jquery plugin that im using is this http://code.google.com/p/jquery-in-place-editor/ if i have a table like this <table> <thead> <tr> <th>id</th> <th>first name </th> <th>last name </th> </tr> </thead> <tbody> <tr> <td class="id">1</td> <td class="fname">sarmen</td> <td class="lname">mikey</td> </tr> <tr> <td class="id">2</td> <td class="fname">john</td> <td class="lname">angelo</td> </tr> <tr> <td class="id">3</td> <td class="fname">sarmen</td> <td class="lname">grande</td> </tr> </tbody> </table> and my js looked something like this $("td.fname").editInPlace({ url: 'ajax.php', params: '', show_buttons: true }); then lets say i click on the first record to edit it which is fname of sarmen. how can i pass a param that only accociates id 1 ? because if i do a query of lets say "update tbl_users set fname = '$_POST['update_value']' where fname = '$_POST['original_html']'" (note: im just showing an example so no need to clean posts if that was bothering you :) ) if i run this query the fname of sarmen will update in two records rather than one. How can i only update to id of 1 being to update only one record.
