  • Sphinx: change column set for searching in runtime

    - by Fedyashev Nikita
    I use Ultrasphinx gem plugin as a wrapper for accessing Sphinx search daemon. My model declaration: class Foo < ActiveRecord::Base is_indexed :fields => ['content', 'private_notes', 'user_id'] Client code: filters = {} if type == "private" # search only in `content` column filters['user_id'] = current_user.id else # search in `content` and `private_notes` columns end results = Ultrasphinx::Search.new(:query => params[:query], :per_page => 20, :page => params[:page] || 1, :filters => filters) The problem I have now with Ultrasphinx gem(or Sphinx, in general?) is that it does not allow me to change set of fields where to look for matches IN RUNTIME How can I solve this problem?

  • PHP Regex Question

    - by oyerli
    Hi, I am developing an application using PHP but I am new to regular expressions, I could not find a solution to my problem. I want to replace all occurences of #word with a link, i have written a preg_match for this: $text=preg_replace('~#([\p{L}|\p{N}]+)~u', '<a href="/?aranan=$1">#$1</a>', $text); The problem is, this regular expression also matches the html character codes like &#039; and gives corrupt output. I need to exclude the words starting with &# but i do not know how to do that using regular expressions. Thanks for your help.

  • How do I know if a drag/drop has been cancelled in WPF

    - by Jon Mitchell
    I'm writing a user control in WPF which is based on a ListBox. One of the main pieces of functionality is the ability to reorder the list by dragging the items around. When a user drags an item I change the items Opacity to 50% and physically move the item in an ObservableCollection in my ViewModel depending on where the user wants it. On the drop event I change the Opacity back to 100%. The problem I've got is that if the user drags the item off my control and drops it somewhere else then I need to change the Opacity back to 100% and move the item back to where it was when the user started the drag. Is there an event I can handle to capture this action? If not is there any other cunning way to solve this problem?

  • Changing a php "echoed" div attribute with php

    - by Zakaria
    Hi everybody, I'm using PHP to echo a content stored on my database. The content is a DIV carrying any type of data. The problem is that I don't know the ID and I have some problems with these DIVs if I try to display them more that once. So, the idea is to modify the DIV id each time I'd like to display them. Something like this: <?php modify_div_id($data,"id-456"); ?> Is there a solution for this problem? Thank you very much, regards.

  • malloc hangs in Linux

    - by Rahul
    I am using Linux on a 16 G with 2 quad core CPU. There are 8 processes which are doing some work (CPU intensive/network i/o). Out of which 4 have a memory leak (These are test conditions so no problem in having leaks here). Total space is occupied by all processes is around 15.4 G only 200 MB is free in system. Things are fine for some hours. But after that malloc hangs (for a process which doesn't have a memory leak). Its stuck for for more than 4 minutes (Note CPU is not 100% but io has gone up signficantly). Now there is no problem in the hanged process. (It has not corrupted the memory). What malloc is doing? (is it tryibg to defragment or builidng up swap space).I am using SUSE 10. Any pointers?

  • MooTools request fails

    - by acoder
    Hi everyone, I am trying to achieve this task using MooTools. Description: I have three buttons. Two buttons outside myDiv and one button inside myDiv. A click on any of these buttons initiates an AJAX request (passing button variable to "button.php") and updates myDiv content based on the response text. So, after update, myDiv shows Button3 link + a message showing which button has been clicked. The problem: Everything seems to work fine but after several clicks, it happens that myDiv shows loader.gif image and stops. After this, if I wait a few moments, the browser sometimes stops working (gets blocked). I noticed this problem with IE6. Does anyone know what does this problem mean and how it can be avoided? index.html <html> <head> <script type="text/javascript" src="mootools/mootools-1.2.4-core-nc.js"></script> <script type="text/javascript" src="mootools/mootools-1.2.4.4-more.js"></script> <script type="text/javascript"> window.addEvent('domready', function() { $("myPage").addEvent("click:relay(a)", function(e) { e.stop(); var myRequest = new Request({ method: 'post', url: 'button.php', data: { button : this.get('id'), test : 'test' }, onRequest: function() { $('myDiv').innerHTML = '<img src="images/loader.gif" />'; }, onComplete: function(response) { $('myDiv').innerHTML = response; } }); myRequest.send(); }); }); </script> </head> <body> <div id="myPage"> <a href="#" id="button1">Button1</a> <a href="#" id="button2">Button2</a> <div id="myDiv"> <a href="#" id="button3">Button3</a> </div> </div> </body> </html> button.php <a href="#" id="button3"Button3</a> <br><br> <?php echo 'You clicked ['.$_REQUEST['button'].']'; ?>

  • Jscrollpane causese text to disappear on internet explorer

    - by Crippletoe
    Hello all, in my current site, i am using the new Jscrollpane in order to generate a scrollbar for a menu (not my descision but the designer's descision so i dont wanna get into how 90's that all looks like..). my menu is based on a <UL> the <li> elements inside it have the attribute "text-align: right;". my problem that on IE alone the menu text doesnt show when i apply the ScrollPane to the menu. when i delete the ScrollPane function from my code- the menu re-appears. i checked the page with "microsoft Expression" DOM inspector in order to examine how IE sees my code and i can see the <li> elements there, only the text inside them is missing. when i disable the "text-align: right;" for the <li> in my CSS, the text shows again. i suspect this has something to do with the jScrollPane's containing which is relatively aligned but i cannot be sure.. can anyone suggest some fix for this problem? a link to a page where you can see the problem is here: http://kaplanoland.com/index.php?option=com_content&view=article&id=2&Itemid=12 the problematic menu is on the right side of the page. on every browser but IE you can see the text. only on IE not. my CSS code for that menu (not including the jScrollPane CSS) is here: div#menu2{ position: absolute; top: 123px; right: 36px; width: 330px; height: 150px; } div#menu2_scroll{ /*the actual scroller*/ height: 150px; } div#menu2 div#menu2_contain{ } div#menu2 li{ text-align: right; } div#menu2 li span{ line-height: 18px; } div#menu2 a:link, div#menu2 a:visited{ color: #808285 ; font-family: Arial, Helvetica, sans-serif ; font-size: 12px ; } div#menu2 a:hover, div#menu2 li#current a{ color: #000000 ; font-family: Arial, Helvetica, sans-serif ; font-size: 12px ; } div#menu2 span.separator{ display: block; padding-top: 12px; padding-bottom: 40px; font-family: Arial, Helvetica, sans-serif; font-size: 12px; font-weight: bold; color: #000000; } div#menu2 span.separator span { padding-top: 12px; border-top-width: 1px; border-top-style: solid; border-top-color: #808285; } thank you all so much.

  • APC not recommended for production?

    - by solomongaby
    I have started having problems with my VPS in the way that it would faill to serve the pages on all the websites. It just showed a blank page, or offered to download the php file ( luckily the code was not in the download file :) ). The server was still running, but this seemed to be a problem with PHP, since i could login into WHM. If i did a apache restart, the sites would work again. After some talks with the server support they told me this is a problem with the APC extension witch they considered to be old and not recommended for production servers. So they removed it for now, to see if the same kind of fails would continue to appear. I haven't read anywhere that APC could have some problems or that its not always recommended to use, quite the contrary ... everywhere people are saying to always use it. The APC extension was installed ssh and is the latest version. Edit: They also dont recomend MemCache and say that a more reliable extension would be eAccelerator

  • qTip with jQuery dialogs

    - by MikeWyatt
    I'm using qTip to show validation errors in a grid. The tooltip appears after a failed row save and doesn't disappear until the row is resaved or the changes are canceled. The problem with this is that opening a dialog while the tooltip is visible causes the tooltip to be rendered on top of the dialog. That is because the z-index is hard-coded to 6000+ for all tooltips, while jQuery dialogs are set to 1000+. I could fix this problem by changing the hard-coded value in qTip to <1000, but then tooltips fired from the dialog will appear behind the dialog. Is there anything I can do, aside from changing the qTip code or using a different tooltip library?

  • BigInteger.Parse() on hexadecimal number gives negative numbers.

    - by brickner
    I've started using .NET 4 System.Numerics.BigInteger Structure and I've encountered a problem. I'm trying to parse a string that contains a hexadecimal number with no sign (positive). I'm getting a negative number. For example, I do the following two asserts: Assert.IsTrue(System.Int64.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "Int64"); Assert.IsTrue(System.Numerics.BigInteger.Parse("8", NumberStyles.HexNumber, CultureInfo.InvariantCulture) > 0, "BigInteger"); The first assert succeeds, the second assert fails. I actually get -8 instead of 8 in the BigInteger. The problem seems to be when I'm the hexadecimal starts with 1 bit and not 0 bit (a digit between 8 and F inclusive). If I add a leading 0, everything works perfectly. Is that a bad usage on my part? Is it a bug in BigInteger?

  • HTML5 Canvas compositing question (source-in)

    - by Alex Ciarlillo
    I am trying to recreate a page flipping type animation in HTML5 using canvas. The animation is based on ideas from here: hxxp://oreilly.com/javascript/archive/flashhacks.html but thats not really important. The problem I am having is that using the 'source-in' composite operation is not giving me the results I expect and would like clarification as to why. Here is the example: (i think it can only be viewed in chrome, not working in FF 3.6) http://acpound.fylez.com/test/example.html The black rectangle is supposed to act as a 'mask' for the page being turned over. All I want to see is the turning page in the areas where it overlaps the mask. The problem is the entire black rectangle is drawn, not just the area where they overlap. The source is all on the page. I know HTML5 isn't really being used yet, I'm just experimenting for my personal site and curiosity. Any ideas would be greatly appreciated.

  • sharpziplib - can you add a file without it copying the entire zip first?

    - by schmoopy
    Im trying to add an existing file to a .zip file using sharpziplib - problem is, the zip file is 1GB in size. When i try to add 1 small file (400k) sharpziplib creates a copy/temp of the orig zip file before adding the new file - this poses a problem when the amount of free disk space is less than 2x the zip file you are trying to update. for example: 1GB zip myfile.zip 1GB zip myfile.zip.tmp.293 ZipFile zf = new ZipFile(path); zf.BeginUpdate(); zf.Add(file); // Adding a 400k file here causes a 1GB temp file to be created zf.EndUpdate(); zf.Close(); Is there a more efficient way to do this? Thanks :-)

  • AS3: resizing as a result of an eventListener

    - by Jaimie
    Hi everyone, I have coded a map that when a province object is clicked on, it should move to the center of the screen and grow a percentage of the width, along with displaying a number of different things. The problem is that in order for the image to resize it needs to be clicked on twice. It moves, and all of the children display just as they were designed to do, but the resize doesn't work on the first try. Any ideas how to fix this problem? ... menuItem4_mc.addEventListener(MouseEvent.CLICK, onClick); ... public function onClick(mc:MouseEvent):void { menuItem4_mc.width = width * .65; menuItem4_mc.height = height * .7; //brings Ontario To the front of the stage setChildIndex(menuItem4_mc,numChildren - 1); menuItem4_mc.x= 670/2; menuItem4_mc.y= 480/2; ... } Thank you!

  • Hooking a synchronous event handler on a form submit button in JS

    - by Xzhsh
    Hi, I'm working on a security project in javascript (something I honestly have not used), and I'm having some trouble with EventListeners. My code looks something like this: function prevclick(evt) { evt.preventDefault(); document.loginform.submitbtn.removeEventListener('click',prevclick,false); var req = new XMLHttpRequest(); req.open("GET","testlog.php?submission=complete",false); req.send(); document.loginform.submitbtn.click(); //tried this and loginform.submit() } document.loginform.submitbtn.addEventListener('click',prevclick,false); But the problem is, the submit button doesn't submit the form on the first click (it does, however, send the http request on the first click), and on the second click of the submit button, it works as normal. I think there is a problem with the synchronization, but I do need to have the request processed before forwarding the user to the next page. Any ideas on this would be great. Thanks in advance.

  • Enumerating combinations in a distributed manner

    - by Reyzooti
    I have a problem where I must analyse 500C5 combinations (255244687600) of something. Distributing it over a 10 node cluster where each cluster processes roughly 10^6 combinations per second means the job will be complete in about 7hours. The problem I have is distributing the 255244687600 combinations over the 10 nodes. I'd like to present each node with 25524468760, however the algorithms I'm using can only produce the combinations sequentially, I'd like to be able to pass the set of elements and a range of combination indicies eg: [0-10^7) or [10^7,2.0 10^7) etc and have the nodes themselves figure out the combinations. The algorithms I'm using at the moment are from the following: http://home.roadrunner.com/~hinnant/combinations.html A logical question I've considered using a master node, that enumerates each of the combinations and sends work to each of the nodes, however the overhead incurred in iterating the combinations from a single node and communicating back and forth work is enormous, and will subsequently lead to the master node becoming the bottleneck. Are there any good combination iterating algorithms geared up for efficient/optimal distributed enumeration?

  • How do you find the last element of an array while iterating using a foreach loop in php ?

    - by Vaibhav Kamble
    I am writing a sql query creator using some parameters. While doing that ,I came across this problem. In java , Its very easy to detect the last element of an array from inside the for loop by just checking the current array position with the array length. for(int i=0; i< arr.length;i++){ boolean isLastElem = i== (arr.length -1) ? true : false; } php has some different fashion. They have non integer indexes to access arrays. So you must iterate over an array using foreach loop. But it becomes very problematic when you need to take some decision (in my case to append or/and parameter while building query). I am sure there must be some standard way of doing this. How do you solve this problem normally in php ?

  • Cannot Generate ParameterSetMetadata While Programmatically Creating A Parameter Block

    - by Steven Murawski
    I'm trying to programmatically create a parameter block for a function ( along the lines of this blog post ). I'm starting with a CommandMetadata object (from an existing function). I can create the ParameterMetadata object and set things like the ParameterType, the name, as well as some attributes. The problem I'm running into is that when I use the GetParamBlock method of the ProxyCommand class, none of my attributes that I set in the Attributes collection of the ParameterMetadata are generated. The problem this causes is that when the GetParamBlock is called, the new parameter is not annotated with the appropriate Parameter attribute. Example: function test { [CmdletBinding()] param ( [Parameter()] $InitialParameter) Write-Host "I don't matter." } $MetaData = New-Object System.Management.Automation.CommandMetaData (get-command test) $NewParameter = New-Object System.Management.Automation.ParameterMetadata 'NewParameter' $NewParameter.ParameterType = [string[]] $Attribute = New-Object System.Management.Automation.ParameterAttribute $Attribute.Position = 1 $Attribute.Mandatory = $true $Attribute.ValueFromPipeline = $true $NewParameter.Attributes.Add($Attribute) $MetaData.Parameters.Add('NewParameter', $NewParameter) [System.Management.Automation.ProxyCommand]::GetParamBlock($MetaData)
