  • problem with two key ranges in couchdb

    - by Duasto
    I'm having problem getting the right results in my coordinate system. To explain my system, I have this simple database that have x_axis, y_axis and name columns. I don't need to get all the data, I just need to display some part of it. For example, I have a coordinate system that have 10:10(meaning from x_axis -10 to 10 and from y_axis -10 to 10) and I want to display only 49 coordinates. In sql query I can do it something like this: "select * from coordinate where x_axis = -3 and x_axis <= 3 and y_axis = -3 y_axis <= 3" I tried this function but no success: "by_range": { "map": "function(doc) { emit([doc.x_axis, doc.y_axis], doc) }" } by_range?startkey=[-3,-3]&endkey=[3,3] I got a wrong results of: -3x-3 -3x-2 -3x-1 -3x0 -3x1 -3x2 -3x3 <-- should not display this part -- -3x4 -3x5 -3x6 -3x7 -3x8 -3x9 -3x10 <-- end of should not display this part -- ..... up to 3x3 to give you a better understanding of my project here is the screenshot of that I want to be made: Oops they don't allowed new poster to post an image img96(dot)imageshack(dot)us/img96/5382/coordinates(dot)jpg <<< just change the "(dot)" to "."

  • simplexml object node iteration

    - by MorbidWrath
    I have an xml file that I'm parsing with php's simplexml, but I'm having an issue with an iteration through nodes. the xml: <channel> <item> <title>Title1</title> <category>Cat1</category> </item> <item> <title>Title2</title> <category>Cat1</category> </item> <item> <title>Title3</title> <category>Cat2</category> </item> </channel> my counting function: public function cat_count($cat){ $count = 0; $items = $this->xml->channel->item; $size = count($size); for($i=0;$i<$size;$i++){ if($items[$i]->category == $cat){ $count++; } } return $count; } Am I overlooking an error in my code, or is there another preferred method for iterating through the nodes? I've also used a foreach and while statement with no luck, so I'm at a loss. Any suggestions?

  • Does it ever make sense to make a fundamental (non-pointer) parameter const?

    - by Scott Smith
    I recently had an exchange with another C++ developer about the following use of const: void Foo(const int bar); He felt that using const in this way was good practice. I argued that it does nothing for the caller of the function (since a copy of the argument was going to be passed, there is no additional guarantee of safety with regard to overwrite). In addition, doing this prevents the implementer of Foo from modifying their private copy of the argument. So, it both mandates and advertises an implementation detail. Not the end of the world, but certainly not something to be recommended as good practice. I'm curious as to what others think on this issue. Edit: OK, I didn't realize that const-ness of the arguments didn't factor into the signature of the function. So, it is possible to mark the arguments as const in the implementation (.cpp), and not in the header (.h) - and the compiler is fine with that. That being the case, I guess the policy should be the same for making local variables const. One could make the argument that having different looking signatures in the header and source file would confuse others (as it would have confused me). While I try to follow the Principle of Least Astonishment with whatever I write, I guess it's reasonable to expect developers to recognize this as legal and useful.

  • Any reason why my $.ajax success callback is not executed in Jquery?

    - by arma
    Hello, Today i discovered that my dev version of my website do not execute success callback, but all other javascript and jquery code is running good. Even my ajax request is performed and i can see response in firebug. $('#login').submit(function(){ var email = $('#l_email').val(); var pass = $('#l_pass').val(); if(email && pass != ''){ var str = decodeURIComponent($(this).serialize()); $.ajax({ type: "POST", url: "login.php", data: str, success: function(msg){ if(msg == 'OK'){ window.location = 'index.php' }else if (msg == 'NOT_OK'){ if(lang == 'lv'){ alert(message); }else if(lang == 'ru'){ alert(message); } }else if (msg == 'EMAIL_NOT_VALID'){ if(lang == 'lv'){ alert(message); }else if(lang == 'ru'){ alert(message); } } } }); }else{ alert('That form is empty.'); } return false; }); The thing is $.ajax part executes fine and i can see response in firebug "OK". But redirect is not happening and even if i replace that redirect with something like alert or console.log nothing comes up. What could cause this? It's really hard to track since firebug gives no errors.

  • How to use linux csplit to chop up massive XML file?

    - by Fred
    Hi everyone, I have a gigantic (4GB) XML file that I am currently breaking into chunks with linux "split" function (every 25,000 lines - not by bytes). This usually works great (I end up with about 50 files), except some of the data descriptions have line breaks, and so frequently the chunk files do not have the proper closing tags - and my parser chokes halfway through processing. Example file: (note: normally each "listing" xml node is supposed to be on its own line) <?xml version="1.0" encoding="UTF-8"?> <listings> <listing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></listing> <listing><date>2009-09-22</date><desc>This is a really annoying description field WITH line breaks that screw the split function</desc><more_tags>stuff</more_tags></listing> </listings> Then sometimes my split ends up like <?xml version="1.0" encoding="UTF-8"?> <listings> <listing><date>2009-09-22</date><desc>This is a description WITHOUT line breaks and works fine with split</desc><more_tags>stuff</more_tags></listing> <listing><date>2009-09-22</date><desc>This is a really annoying description field WITH line breaks ... EOF So - I have been reading about "csplit" and it sounds like it might work to solve this issue. I cant seem to get the regular expression right... Basically I want the same output of ~50ish files Something like: *csplit -k myfile.xml '/</listing>/' 25000 {50} Any help would be great Thanks!

  • Pushing elements into array as copy

    - by koko
    In prototypejs, why does the following code remove the matching divs from the #test div? What confuses me is that this happens when they are being inserted in the #droparea, and not when they are being pushed in the array. <div id="test"> <div class="foo" id="22.1234"> 1 </div> <div class="foo" id="22.1235"> 2 </div> <div class="foo" id="53.2345"> 3 </div> <div class="foo" id="53.2346"> 4 </div> </div> <div id="droparea"> </div> js var elArray = []; var els = $('test').select('.foo'); els.each(function(x){ if(x.id.split('.')[0] == 22){ elArray.push(x); } }); elArray.each(function(y){ $('droparea').insert({ bottom: y }); });

  • WPML is not detecting Wordpress custom post types

    I learned how to make custom post types with the following tutorial: http://sixrevisions.com/wordpress/wordpress-custom-post-types-guide/ It basically consist in adding this code to function.php: add_action( 'init', 'create_events' ); function create_events() { $labels = array( 'name' => _x('Events', 'post type general name'), 'singular_name' => _x('Event', 'post type singular name'), 'add_new' => _x('Add New', 'Event'), 'add_new_item' => __('Add New Event'), 'edit_item' => __('Edit Event'), 'new_item' => __('New Event'), 'view_item' => __('View Event'), 'search_items' => __('Search Events'), 'not_found' => __('No Events found'), 'not_found_in_trash' => __('No Events found in Trash'), 'parent_item_colon' => '' ); $supports = array('title', 'editor', 'custom-fields', 'revisions', 'excerpt'); register_post_type( 'event', array( 'labels' => $labels, 'public' => true, 'supports' => $supports ) ); } The WPML plugin help you to translate posts to different langauges. But this option doesn't appear in the custom post types. Any suggestions?

  • JQuery: Live <a> tag partially working second time around.

    - by BPotocki
    I have the following jquery code: $("a[id*='Add_']").live('click', function() { //Get parentID to add to. var parentID = $(this).attr('id').substring(4); //Get div. var div = $("#CreateList"); //Ajax call to refresh "CreateList" div with new XML. div.load("/AddUnit?ParentID=" + parentID); }); Basically, contained within the div is a nested unordered list with several "Add_#" links. Clicking the links uses an ajax call to recreate the list with a new node. It clears all the add links, but they are added again by the ajax call. This is why I used the .live method so newly added "Add_#" links still have the binding. This works in most cases. If I click "Add_1", the div refreshes with the new info. If I then click "Add_2", it works again as expected. The problem I'm having happens when I click "Add_1", then the page refreshes (and creates a new "Add_1" link), then I click the re-rendered "Add_1" again. It's the same link, but it was refreshed during the ajax call. When I do that, the javascript function still gets called, but the .load method doesn't work. Any ideas why this might be happening? Thanks.

  • Create a variable which is named depending on an ID number?

    - by gray
    Is there any way to create a variable, and add an ID to the end of the actual variable name? I have a variable called 'gauge', used to create a new Gauge object: var gauge = new Gauge(target).setOptions(opts); I want to add an ID to the variable, so something like: var gauge+id = new Gauge(target).setOptions(opts); It's because I'm creating a number of these objects, and have a specific ID already for each one, which I want to attach to the gauge object if possible? All my code for this function is below, if it gives you a better idea of what i need to do: function go(id, votes) { var val = $('#votes_'+id).text(); var target = document.getElementById('foo_'+id); // your canvas element var gauge = new Gauge(target).setOptions(opts); // create sexy gauge! gauge.maxValue = 100; // set max gauge value gauge.animationSpeed = 20; // set animation speed (32 is default value) var a=votes+0.5; gauge.set(val); // set actual value } My main problem arises on the last line. It says gauge.set(val), and it only sets the last object, ignoring all the other ones...

  • Facebook fbAsyncInit firing twice

    - by JoelD
    I'm using Facebook's Javascript SDK to allow login/logout, and my problem is that when I use their window.fbAsyncInit call to initiate the FB session, it always fires twice. I've included a simplified code sample. I'd appreciate any help! <html><head> <script type="text/javascript"> ...some of my own functions, not related to Facebook... </script> </head> <body> <div id="fb-root"></div> <script> window.fbAsyncInit = function() { FB.init({ appId : '<?php echo FACEBOOK_APPID; ?>', session : <?php echo json_encode($session); ?>, status:false, cookie:true, xfbml: true }); alert("1"); FB.getLoginStatus(function(response) { if(response.session) { ...do stuff... } else { ...do other stuff...} }); }; alert("2"); </script> ...page contents... </body></html> The "2" alert fires a single time, and then the "1" alert fires twice.

  • Updating Embedded Video in Firefox

    - by Slevin
    I am working on a Videos page where my intention is to load a video with the page but by clicking a link, the original video will be updated and replaced with the corresponding video. For instance, if video1 loads with the page and the user clicks to view video2, the original div's innerHTML holding video1 is updated to play video2. Now, I have works great in IE and Chrome but nothing loads at all in Firefox. Below are some snippets of my code. Any idea how to load these videos in a manner that Firefox supports? Javascript Function function updateVideo(arraynum) { var arraynum; var vidId = document.anchors(arraynum).name; document.getElementById("movieDiv").innerHTML = "<object width='340' height='300'><param name='movie' value='http://www.youtube.com/v/" + vidId + "&h1=en&fs=1&color1=0x5d1719&color2=0xcd311b'></param><param name='wmode' value='opaque'></param><embed src='http://www.youtube.com/v/" + vidId + "&h1=en&fs=1&color1=0x5d1719&color2=0xcd311b' type='application/x-shockwave-flash' wmode='opaque' width='340' height='300'></embed></object>"; Html <div id = "movieDiv"> </div> Links <a name="-MQf_Ol00nk" href = "#" onclick="updateVideo(4)"><img src="../images/content/videos/kaleidoscope/2010/May/Arts-and-Events.jpg" border = "0"></a> Any help with this issue would be greatly appreciated. And on a smaller note, every time a link in clicked in IE, a '#' is added into the title bar. So clicking three or four videos would result in the page title being followed up with three or four # signs.

    Pretty new to jQuery, so I'm hoping someone can help me out... There's a couple of things going on here... Help with any part of it is appreciated. For starters, I'm trying to append a row to a table when a user clicks in the first enabled input field for that row. Here's the code I'm trying to use: $("#fitable > tbody > tr > td > input").bind('focus', function() { if($(this).attr('disabled', false)) { $(this).click(function() { var newRow = '<tr><td><input name="f1[]" value="" /><label>CustNew</label></td><td><input name="field_n1[]" value="" /><label>N1</label></td><td><input name="field_n2[]" value="" /><label>N2</label></td></tr>'; $(this).closest("tbody").append(newRow); }); } }); If it's helpful, here's the html: <table id="fitable"> <tbody> <tr valign="top"> <td><input disabled="disabled" name="cust" id="edit-cust" value="[email protected]" type="text"><label>Cust</label></td> <td><input name="field_n1[]" value="" type="text"><label>N1</label></td> <td><input name="field_n2[]" value="" type="text"><label>N2</label></td> </tr> </tbody> </table>

  • Lucene.Net: How can I add a date filter to my search results?

    - by rockinthesixstring
    I've got my searcher working really well, however it does tend to return results that are obsolete. My site is much like NerdDinner whereby events in the past become irrelevant. I'm currently indexing like this Public Function AddIndex(ByVal searchableEvent As [Event]) As Boolean Implements ILuceneService.AddIndex Dim writer As New IndexWriter(luceneDirectory, New StandardAnalyzer(), False) Dim doc As Document = New Document doc.Add(New Field("id", searchableEvent.ID, Field.Store.YES, Field.Index.UN_TOKENIZED)) doc.Add(New Field("fullText", FullTextBuilder(searchableEvent), Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("user", If(searchableEvent.User.UserName = Nothing, "User" & searchableEvent.User.ID, searchableEvent.User.UserName), Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("title", searchableEvent.Title, Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("location", searchableEvent.Location.Name, Field.Store.YES, Field.Index.TOKENIZED)) doc.Add(New Field("date", searchableEvent.EventDate, Field.Store.YES, Field.Index.UN_TOKENIZED)) writer.AddDocument(doc) writer.Optimize() writer.Close() Return True End Function Notice how I have a "date" index that stores the event date. My search then looks like this ''# code omitted Dim reader As IndexReader = IndexReader.Open(luceneDirectory) Dim searcher As IndexSearcher = New IndexSearcher(reader) Dim parser As QueryParser = New QueryParser("fullText", New StandardAnalyzer()) Dim query As Query = parser.Parse(q.ToLower) ''# We're using 10,000 as the maximum number of results to return ''# because I have a feeling that we'll never reach that full amount ''# anyways.

    I use a dynamic table: <html> <body> <button id="button">Build table</button> <div id="container"> <script type="text/javascript"> window.onload=function(){ var table = null; var row = "<tr><td>111111111111111111111111111111111111111111111111111111</td>" + "<td>222222222222222222222222222222222222222222222222222222</td>" + "<td>333333333333333333333333333333333333333333333333333333</td></tr>"; var data = null; for (var i = 0; i < 2000; i++){ data += row; } var obj = document.getElementById("button"); obj.onclick=function buildTable(){ document.getElementById("container").innerHTML = "<div><table><tbody>" + data + "</tbody></table></div>"; }; }; </script> </body> </html> Using chromes task manager, each time new data is loaded the memory usage increases considerably and doesn't go down, so after some time the app consumes a lot of memory and requires the browser to be closed. Is there any change in the code I can use to solve this or is it a browser side problem?

  • Multi Player game using Nodejs and Socket IO

    - by Kishorevarma
    I am trying out multi player racing game using Node and Socket IO ,express . So I have tried simple example to see the latency between node server and the clients. I have a draggable image in client . when I move the image ienter code heren one client ,it has to move in all clients. so basically when I am moving the image I am sending the image position to the node server in a json format , then from there I am broadcasting to all clients. there is a ~approx 300ms latency from the time. following are the results. Client 1 sending data to server at : 286136 (timestamp) Server received at : 286271 Client2 received data at : 286470 Client3 received data at : 286479 Client4 received data at : 286487 Client5 received data at : 286520 the latency between move from client1 to client5 is 384ms. its too hight for a racing game .. here is my server code. var app = require('express').createServer(); var io = require('socket.io'); var http = require('http'); var http_server = http.createServer(); var server = http.createServer(app); server.listen(3000); var socket = io.listen(server,{ log: false }); socket.sockets.on('connection', function (client) { client.on('message', function (data){ console.log("data arrived to server",new Date().getTime()); // Below both statements are giving same latency between the client 1 and client 5 client.broadcast.emit('message',data); //socket.sockets.emit('message',data); }); }); 1) Is there any way to optimize the server code to reduce the latency? 2) is this expected latency using node and websockets ? 3) is socket io can't broadcast the data asynchronously (I mean at a same time) ? Thanks Kishorevarma

  • Getting empty update rectangle in OnPaint after calling InvalidateRect on a layered window

    - by Shawn
    I'm trying to figure out why I've been getting an empty update rectangle when I call InvalidateRect on a transparent window. The idea is that I've drawn something on the window (it gets temporarily switched to have an alpha of 1/255 for the drawing), and then I switch it to full transparent mode (i.e. alpha of 0) in order to interact with the desktop & to be able to move the drawing around the screen on top of the desktop. When I try to move the drawing, I get its bounding rectangle & use it to call InvalidateRect, as such: InvalidateRect(m_hTarget, &winRect, FALSE); I've confirmed that the winRect is indeed correct, and that m_hTarget is the correct window & that its rectangle fully encompasses winRect. I get into the OnPaint handler in the class corresponding to m_hTarget, which is derived from a CWnd. In there, I create a CPaintDC, but when I try to access the update rectangle (dcPaint.m_ps.rcPaint) it's always empty. This rectangle gets passed to a function that determines if we need to update the screen (by using UpdateLayeredWindow in the case of a transparent window). If I hard-code a non-empty rectangle in here, the remaining code works correctly & I am able to move the drawing around the screen. I tried changing the 'FALSE' parameter to 'TRUE' in InvalidateRect, with no effect. I also tried using a standard CDC, and then using BeginPaint/EndPaint method in my OnPaint handler, just to ensure that CPaintDC wasn't doing something odd ... but I got the same results. The code that I'm using was originally designed for opaque windows. If m_hTarget corresponds to an opaque window, the same set of function calls results in the correct (i.e. non-empty) rectangle being passed to OnPaint. Once the window is layered, though, it doesn't seem to work right.
