  • PHP: Convert web-page to utf8

    - by Paul Tarjan
    I would like to only work with UTF8. The problem is I don't know the charset of every webpage. How can I detect it and convert to UTF8? <?php $url = "http://vkontakte.ru"; $ch = curl_init($url); $options = array( CURLOPT_RETURNTRANSFER => true, ); curl_setopt_array($ch, $options); $data = curl_exec($ch); // $data = magic($data); print $data; See this at: http://paulisageek.com/tmp/curl-utf8 What is magic()?

    There are many class="item" blocks on the page. For each one there is different var item_link and ajax request.

Thanks.

  • How can Java assignment be made to point to an object instead of making a copy?

    - by Matthew Piziak
    In a class, I have: private Foo bar; public Constructor(Foo bar) { this.bar = bar; } Instead of creating a copy of bar from the object provided in the parameter, is it possible to include a pointer to bar in the constructor such that changing the original bar changes the field in this object? Another way of putting it: int x = 7; int y = x; x = 9; System.out.print(y); //Prints 7. It is possible to set it up so that printing y prints 9 instead of 7?

  • Converting a macro to an inline function

    - by Rob
    I am using some Qt code that adds a VERIFY macro that looks something like this: #define VERIFY(cond) \ { \ bool ok = cond; \ Q_ASSERT(ok); \ } The code can then use it whilst being certain the condition is actually evaluated, e.g.: Q_ASSERT(callSomeFunction()); // callSomeFunction not evaluated in release builds! VERIFY(callSomeFunction()); // callSomeFunction is always evaluated Disliking macros, I would instead like to turn this into an inline function: inline VERIFY(bool condition) { Q_ASSERT(condition); } However, in release builds I am worried that the compiler would optimise out all calls to this function (as Q_ASSERT wouldn't actually do anything.) I am I worrying unnecessarily or is this likely depending on the optimisation flags/compiler/etc.? I guess I could change it to: inline VERIFY(bool condition) { condition; Q_ASSERT(condition); } But, again, the compiler may be clever enough to ignore the call. Is this inline alternative safe for both debug and release builds?

  • Interpreted vs. Compiled Languages for Web Sites (PHP, ASP, Perl, Python, etc.)

    - by Andrew Swift
    I build database-driven web sites. Previously I have used Perl or PHP with MySQL. Now I am starting a big new project, and I want to do it in the way that will result in the most responsive possible site. I have seen several pages here where questions about how to optimize PHP are criticized with various versions of "it's not worth going to great lengths to optimize PHP since it's an interpreted language and it won't make that much difference". I have also heard various discussions (especiallon on the SO podcast) about the benefits of compiled vs. interpreted languages, and it seems as though it would be in my interests to use a compiled language to serve up the site instead of an interpreted language. Is this even possible in a web context? If so, what would be a reasonable language choice? In addition to speed one benefit I forsee is the possiblity of finding bugs at compile time instead of having to debug the web site. Is this reasonable to expect?

  • In a C++ template, is it allowed to return an object with specific type parameters?

    - by nieldw
    When I've got a template with certain type parameters, is it allowed for a function to return an object of this same template, but with different types? In other words, is the following allowed? template<class edgeDecor, class vertexDecor, bool dir> Graph<edgeDecor,int,dir> Graph<edgeDecor,vertexDecor,dir>::Dijkstra(vertex s, bool print = false) const { /* Construct new Graph with apropriate decorators */ Graph<edgeDecor,int,dir> span = new Graph<edgeDecor,int,dir>(); /* ... */ return span; }; If this is not allowed, how can I accomplish the same kind of thing?

  • How do I get the output from a Perl pipe as it becomes available?

    - by Uri
    The following code is working sort of fine: open( PIPE, '-|', 'ant' ); for( <PIPE> ) { print; } However, it doesn't do what I want. Since the Ant build can take 5 minutes, I would like to see the output line by line. Instead, I'm getting the entire input at the end of the process. Looking at it with the Perl debugger, Perl waits at the 'for' statement, until Ant terminates. Why is that?

  • animate each child jquery

    - by Martavis P.
    It's amazing how simple this should be but I can't get it to work. I'm looking to animate a set of divs one at a time. I am using animate.css for those familiar with it. I thought I may have found the answer here but jsFiddle is not working at the moment. Anywho, the code is $('.elements').each(function(i) { $(this).addClass('animated slideInLeft').delay(500); }); The problem is that when I debug and step through each element, the animation is happening for each element but when I let it run, it appears to all do it at once. What is needed to actually show the animation one at a time? Thanks EDIT: jsFiddle is back up and that link provided below did not help. The answer did not include looping through elements, but looping the animation itself. EDIT 2 Here is a Fiddle to play with if you guys need one.

  • App shuts down when pushing UIbutton!

    - by maralbjo
    For reasons unknown my app shuts down upon pressing a UIButton in the simulator. I have dynamically added my UIView, if that is of relevance. No tracelog or debug information just a rush exit... This is the simple code (.m-file): - (IBAction) testButtonPressed: (id) sender{ NSLog (@"Testbutton pressed."); } From the header file: - (IBAction) testButtonPressed: (id) sender; Pretty basic stuff, but for some reason the app terminates. Help!

  • Writing To The Response in Rails? (Like "echo" in PHP)

    - by Yar
    I know that I can do this in Rails: <%="hello" %> but is there any way to do this <% echo "hello" %> and get it to show up in the response? I have tried response.write which almost worked, but did not... Edit: print or puts do not do it, because I do not want to write to the console. I want to write to the browser/HTTP client. Edit: Here is an example: <% unless @research_activities.size == 0 concat(render(:partial => 'list')) end %> Why would I want to include two closing tags just to do that? It reads nicely in code, doesn't it?

  • Reading from CSVs in Python repeatedly?

    - by matt
    I'm trying to check the value of extracted data against a csv I already have. It will only loop through the rows of the CSV once, I can only check one value of feed.items(). Is there a value I need to reset somewhere? Is there a better/more efficient way to do this? Thanks. orig = csv.reader(open("googlel.csv", "rb"), delimiter = ';') goodrows = [] for feed in gotfeeds: for link,comments in feed.items(): for row in orig: print link if link in row[1]: row.append(comments) goodrows.append(row)

  • Inconsistent behaviour from SDL_BlitSurface

    - by bardes
    Here is an example code: #include <SDL/SDL.h> #include <SDL/SDL_image.h> #include <stdio.h> int main() { if(SDL_Init(SDL_INIT_EVERYTHING) == -1) { printf("SDL ERROR: %s", SDL_GetError()); return 1; } SDL_Surface *screen; screen = SDL_SetVideoMode(128, 128, 32, SDL_SWSURFACE); SDL_Surface *img; img = IMG_Load("./debug.png"); SDL_BlitSurface(img, NULL, screen, NULL); SDL_Flip(screen); SDL_Delay(1000); SDL_FreeSurface(img); SDL_Quit(); return 0; } It compiles fine, but when I run it sometimes it works and most times only part of the image is displayed. I really can't imagine what's causing that... EDIT: This is the image I'm using to test the program: http://img140.imageshack.us/img140/3858/debugi.png

  • Debugging in netbeans (java)

    - by Daen
    I have been asking this myself for a while. Debugging in visual studio goes smooth. But when i debugg in Netbeans(java) i find myself more then half of the time browsing trough the system code itself. This makes it almost unpossible for me to detect hard to find bugs, cause debugging simply is to tedious and unmanageable. How can this be avoided? Stepping out all the time takes a insane amount of time, and i only wish to debug the code i have written down. I usally add all the controls myself without using any drag and drop for forms if that makes any difference in the total picture. Regards.

  • Is this a php memory leak?

    - by mseifert
    I have memory_get_usage() in the footer of my page and with each refresh of the page, I watch it increase by about 100k each time. My page load creates many objects and destroys them when done . My parent objects each have __destruct() which uses unset() with all child objects. Child objects with a reference back to the parent, have __destruct() to unset() these references. Inserting memory_get_usage() before and after processing different parts of my page only tells me how much of the total usage was added due to that part of the script. How do I go about determining what memory is lost and not recycled for garbage collection after the page finishes loading? I have one global $_SESSION var containing objects storing user info, but have verified using strlen(serialize($object)) that this object is not growing in size. I presume that what I am seeing is a memory leak and that php garbage collection should be in effect after the script ends. Any ideas how to debug this?

  • casting a node to integer

    - by user1708762
    The code gives an error saying that "no operator matches these two operands" in the if comparison statement. I interpret,it should mean that "a node can't be converted/casted into an integer". But, the print statement prints an integer value for w[2] when used with %d format. Why is that happening? Isn't printf casting it? NODE *w=(NODE *)malloc(4*sizeof(NODE)); if(w[2]==0) printf("%d\n",w[2]); The structure of the node is- struct node{ int key; struct node *father; struct node *child[S]; int *ss; int current; };

  • When I add elements to a dictionary, the elements are also added to another dictionary (C# + XNA)

    - by sFuller
    I have some code that looks like this: public static class Control { public static Dictionary<PlayerIndex, GamePadState> gamePadState = new Dictionary<PlayerIndex,GamePadState>(); public static Dictionary<PlayerIndex, GamePadState> oldGamePadState = new Dictionary<PlayerIndex, GamePadState>(); public static void UpdateControlls() { gamePadState.Clear(); foreach (PlayerIndex pIndex in pIndexArray) { gamePadState.Add(pIndex,GamePad.GetState(pIndex)); } } } As I looked through the code in Debug, when I called gamePadState.Add(...);, It also added to oldGamePadState, even though I never called oldGamePadState.Add(...); This is verry strange. Thanks everybody!
