  • Can i use a Windows 2008 r2 Cluster for file redundancy

    - by JERiv
    I'm researching a sever clustering architecture as a redundancy and backup solution for a client, and something that isn't made clear is whether or not i can use server clustering to replace a file server with backup solution. Forgive my Elementary understanding of server clustering but supposing: 2 Sites (NJ, CA) Identical Servers at each site setup as a Remote Site Cluster nodes with Windows Enterprise server 2008 r2 Services: File, Terminal, AD, and maybe DNS Will the following will be true: Files (including data drives) will be synced between the two servers eliminating the need for third party backup/mirroring software to sync/backup files. Also supposing i use roaming profiles w/ folder redirection; How will client computer in the WAN access their data through the cluster (i.e. will they automatically choose the best route)

  • Redirect an URL to another URL with Apache and WAMP?

    - by user1719496
    I was wondering how to make a simple redirection, I've got WAMP installed on my computer and I wish I could do that: When I go to abc.com it redirects to xyz.com. I did this in the httpd.conf file, but it isn't working. It seems to work now, but only when I go to localhost. However, what I want is that when I go to abc.com it goes to xyz.com, and I can't do that. Here is my conf : <VirtualHost *:80 > ServerName abc.com Redirect permanent / http://www.xyz.com/ </VirtualHost>

  • Entire folders deleted from My Documents periodically with remote logins

    - by darron
    I've got a customer who thinks our application is constantly deleting all it's data. It's really becoming a major problem for them. The problem is, there's no way it's us. They are losing not only our entire data folder (which we locate in the user's "My Documents" folder to make it easy to find), but some local settings files which are in entirely different places within the general user profile. It REALLY looks like the entire user is either getting reset, or is somehow synchronizing with a more... blank profile somewhere else. They're running this on some kind of virtualized Citrix guest OS. I see references to a "group policy folder redirection" that could do this... maybe roaming profiles? Any ideas? Help!

  • My monitor constantly changes from DVI-D to HD15

    - by guest
    I noticed this lately, and it's becoming more often. Basically, when I start my PC, my monitor, which is connected with a DVI-D cable (I don't know what it's called), screen switches to the HD15, where HD15 isn't connected at all. Like, input is changed from DVI-D to HD15, therefore it just blacks out, and then goes back... it's not constant, but it's in random time intervals... I can't do anything on my computer because of this. I even tried connecting it with both DVI-D cable and HD15 cable to the processor, but it still sucks. Is there any way I could force my monitor to stay at only one input method? I'm on XP SP3, and this monitor is about 10 or less years old, a Sony model.

  • Possible to create "fake" forum (for prototyping) using html, javascript, jquery, css? [closed]

    - by htmlNewbie
    I am trying to figure out if it might be possible to create a small forum without any use of a database and php coding. I have created a small (local and will only be local) webpage with a couple of menus. I have a forum button which will take me to another .html location. Here i would like to create something that looks like a forum and which you somewhat could interact with like a forum, without any database or PHP. I would probably want/need a form with a heading and text input. When i have given some input, i want it to be displayed as a thread, probably on top of the other threads (which will have to be created beforehand). When I refresh the forum will obviously be set to default, without saving what i just entered since I'm not using a database to save any data. So the new posts will not be saved, just displayed, neatly, when submitted. I'm doing this webpage with forum just as a prototype, and that is why it doesn't have to work as a professional forum. :) Would be very thankful for some tips, tricks, ideas or links to helpful threads.

    - by Kortyell Davis
    i have a fedora server running apache web server. the server is connected to a home network. i have a laptop connected to the same network. i can enter the ip address of my server into the browser of my laptop and pull up the index.html file located in the document root directory of the fedora home server. the index.html file contains jquery code. the jquery code only works when i open it locally in my browser (e.g. right click open with firefox), but when i attempt to view the webpage from my laptop the jquery code is not executed. the code is here below. <script type="text/javascript" src="jquery-1.8.2.js"></script> ' $(document).ready(function() { $('#form').hide(); $('input[type=text]').focus(function() { $(this).val(''); }); $('input[type=password]').focus(function() { $(this).val(''); }); $('.form').hide(); $('#log').click(function(){ $('#form').toggle(); }); $('#reg').click(function(){ $('.form').toggle(); }); });

  • How to swap or move 2 string in Array? [on hold]

    - by Wisnu Khazefa
    I have a need to convert .csv file to .dat file. In my problem, there are value pairs, with a name attribute (called Fund) and corresponding numeric value. If the input file has a pair whose value is 0, then that pair (Fund and value) is dropped. The output file should have only those pairs (Fund and value) where the value is non-zero. Here is the prototype of my code. public static void Check_Fund(){ String header = "Text1,Text2,Text3,FUND_UALFND_1,FUND_UALPRC_1,FUND_UALFND_2," +"FUND_UALPRC_2,FUND_UALFND_3,FUND_UALPRC_3,FUND_UALFND_4,FUND_UALPRC_4,FUND_UALFND_5,FUND_UALPRC_5,Text4,Text5,Text6,Text7"; String text = "ABC;CDE;EFG;PRMF;0;PRFF;50;PREF;0;PRCF;0;PRMP;50;TAHU;;BAKWAN;SINGKONG"; String[] head; String[] value; String showText = ""; head = header.split(","); value = text.split(";"); String regex = "\\d+"; String[] fund = {"PREF","PRMF","PRFF","PRCF","PRMP","PDFF","PSEF","PSCB","PSMF","PRGC","PREP"}; for(int i = 0; i < value.length; i++){ for(int j=0;j < fund.length; j++){ if(value[i].equals(fund[j]) && value[i+1].matches(regex)){ if(value[i+1].equals("0")){ value[i] = ""; value[i+1] = ""; } } } showText = showText + head[i] +":" + value[i] + System.lineSeparator(); } System.out.println(showText ); } Expected Result Input: FUND_UALFND_1:PRMF FUND_UALPRC_1:0 FUND_UALFND_2:PRFF FUND_UALPRC_2:50 FUND_UALFND_3:PREF FUND_UALPRC_3:0 FUND_UALFND_4:PRCF FUND_UALPRC_4:0 FUND_UALFND_5:PRMP FUND_UALPRC_5:50 Output: FUND_UALFND_1:PRFF FUND_UALPRC_1:50 FUND_UALFND_2:PRMP FUND_UALPRC_2:50 FUND_UALFND_0: FUND_UALPRC_0: FUND_UALFND_0: FUND_UALPRC_0: FUND_UALFND_0: FUND_UALPRC_0:

  • Issue with Administratively Assigned Offline Files

    - by ZnewmaN
    I need to use Administratively Assigned Offline files in conjunction with folder redirection, but user home folders live on 26 different shares. Do I just need to add 52 file paths similar to: \\server\shareA\%username%\Desktop \\server\shareA\%username%\My Documents \\server\shareB\%username%\Desktop \\server\shareB\%username%\My Documents ... and so on? Or do I need to create 26 GPOs, one for each share; or is there an easier way to do it? Edit: The solution provided by @berniewhite in the comments of using %homeshare% has resolved the issue and Administratively Assigned Offline Files is now working well.

  • Using Power Adapter With Slightly Different Rating - Close Enough? [closed]

    - by Ed Liddiard
    Possible Duplicate: Laptop power supplies, does current matter? I'm in Colombia, South America and the power adapter on my HP Pavilion DV4-1125nr laptop died. The adapter is rated at 65W input 1.6A & output 18.5V 3.5A. A friend found me a Dell adapter rated at 65W input 1.5A & output 19.5V 3.34A. Both have center + polarities. Seems very stable and not having unusual heat problems. Do you think it is safe to use this adapter without harming my laptop?

  • Phishing attack stuck with jsp loginAction.do page? [closed]

    - by user970533
    I 'm testing a phishing website on a staged replica of an jsp web-application. I'm doing the usual attack which involves changing the post and action field of source code to divert to my own written jsp script capture the logins and redirect the victim to the original website. It looks easy but trust me its has been me more then 2 weeks I cannot write the logins to the text file. I have tested the jsp page on my local wamp server it works fine. In staged when I click on the ok button for user/password field I'm taken to loginAction.do script. I checked this using tamper data add on on firefox. The only way I was able to make my script run was to use burp proxy intercept the request and change action parameter to refer my uploaded script. I want to know what does an loginAction.do? I have googled it - its quite common to see it in jsp application. I have checked the code; there is nothing that tells me why the page always point to the .do script instead of mine. Is there some kind of redirection in tomcat configuration. I like to know. I'm unable to exploit this attack vector? I need the community help

  • Parallelize code using CUDA [migrated]

    - by user878944
    If I have a code which takes struct variable as input and manipulate it's elements, how can I parallelize this using CUDA? void BackpropagateLayer(NET* Net, LAYER* Upper, LAYER* Lower) { INT i,j; REAL Out, Err; for (i=1; i<=Lower->Units; i++) { Out = Lower->Output[i]; Err = 0; for (j=1; j<=Upper->Units; j++) { Err += Upper->Weight[j][i] * Upper->Error[j]; } Lower->Error[i] = Net->Gain * Out * (1-Out) * Err; } } Where NET and LAYER are structs defined as: typedef struct { /* A LAYER OF A NET: */ INT Units; /* - number of units in this layer */ REAL* Output; /* - output of ith unit */ REAL* Error; /* - error term of ith unit */ REAL** Weight; /* - connection weights to ith unit */ REAL** WeightSave; /* - saved weights for stopped training */ REAL** dWeight; /* - last weight deltas for momentum */ } LAYER; typedef struct { /* A NET: */ LAYER** Layer; /* - layers of this net */ LAYER* InputLayer; /* - input layer */ LAYER* OutputLayer; /* - output layer */ REAL Alpha; /* - momentum factor */ REAL Eta; /* - learning rate */ REAL Gain; /* - gain of sigmoid function */ REAL Error; /* - total net error */ } NET; What I could think of is to first convert the 2d Weight into 1d. And then send it to kernel to take the product or just use the CUBLAS library. Any suggestions?

  • Possible to run system-config-network during %post kickstart?

    - by tore-
    Hello, I'm currently trying to figure out a smart way to set IP, hostname, gateway and DNS settings during a kickstart (with user input during the kickstart). Doing this with firstboot after the install is not acceptable, so this must be done during %post. I've tried to run the system-config-network tool during post in tty6: #!/bin/sh chvt 6 exec < /dev/tty6 > /dev/tty6 /usr/bin/system-config-network-tui This doesn't work since for some reason I'm unable to catch user input. I would prefer to use built in tools to change this during post, rather than write my own bash script to do this, since using the provided tools is less likely to break anything. Does someone done anything like this or similar, and made it work? Thanks

  • SignalR cannot read property client of undefined

    - by polonskyg
    I'm trying to add SignalR to my project (ASPNET MVC 4). But I can't make it work. In the below image you can see the error I'm receiving. I've read a lot of stackoverflow posts but none of them is resolving my issue. This is what I did so far: 1) Ran Install-Package Microsoft.AspNet.SignalR -Pre 2) Added RouteTable.Routes.MapHubs(); in Global.asax.cs Application_Start() 3) If I go to http://localhost:9096/Gdp.IServer.Web/signalr/hubs I can see the file content 4) Added <modules runAllManagedModulesForAllRequests="true"/> to Web.Config 5) Created folder Hubs in the root of the MVC application 6) Moved jquery and signalR scripts to /Scripts/lib folder (I'm not using jquery 1.6.4, I'm using the latest) This is my Index.cshtml <h2>List of Messages</h2> <div class="container"> <input type="text" id="message" /> <input type="button" id="sendmessage" value="Send" /> <input type="hidden" id="displayname" /> <ul id="discussion"> </ul> </div> @section pageScripts { <!--Reference the SignalR library. --> <script src="@Url.Content("~/Scripts/jquery.signalR-1.0.0-rc1.min.js")" type="text/javascript"></script> <!--Reference the autogenerated SignalR hub script. --> <script type="text/javascript" src="~/signalr/hubs"></script> <script src="@Url.Content("~/Scripts/map.js")" type="text/javascript"></script> } This is my IServerHub.cs file (located inside Hubs folder) namespace Gdp.IServer.Ui.Web.Hubs { using Microsoft.AspNet.SignalR.Hubs; [HubName("iServerHub")] public class IServerHub : Hub { public void Send(string name, string message) { Clients.All.broadcastMessage(name, message); } } } And this is map.js $(function () { // Declare a proxy to reference the hub. var clientServerHub = $.connection.iServerHub; // Create a function that the hub can call to broadcast messages. clientServerHub.client.broadcastMessage = function (name, message) { $('#discussion').append('<li><strong>' + name + '</strong>:&nbsp;&nbsp;' + message + '</li>'); }; // Get the user name and store it to prepend to messages. $('#displayname').val(prompt('Enter your name:', '')); // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.start().done(function () { $('#sendmessage').click(function () { // Html encode display name and message. var encodedName = $('<div />').text($('#displayname').val()).html(); var encodedMsg = $('<div />').text($('#message').val()).html(); // Call the Send method on the hub. clientServerHub.server.send(encodedName, encodedMsg); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); }); The DLL's I see references for SignalR are: Microsoft.AspNet.SignalR.Core Microsoft.AspNet.SignalR.Owin Microsoft.AspNet.SignalR.SystemWeb Any ideas how to get it work? Should I make any change because the scripts are in /Script/lib folder? NOTE I'm following the instruction found here on how to set up Windsor Castle to make it work with SignalR, and again, seems that the proxy cannot be created and I'm getting the same error: Cannot read property client of undefined meaning that the proxy to the hub was not created This is how I have it in the server public class IncidentServerHub : Hub and like this in the client var clientServerHub = $.connection.incidentServerHub; Again, I can see the dynamically created file here: /GdpSoftware.Server.Web/signalr/hubs So, Why the proxy is not created? Thanks in advance!!! Guillermo.

  • JS regex isn't matching, even thought it works with a regex tester

    - by Tom O
    I'm writing a piece of client-side javascript code that takes a function and finds the derivative of it, however, the regex that's supposed to match with the power rule fails to work in the context of the javascript program, even though it sucessfully matches when it's used with an independent regex tester. The browser I'm executing this on is Midori, and the operating system is Ubuntu 10.04 (Lucid Lynx). Here's the HTML page being used as the interface in addition to the code: Page: <html> <head> <title> Derivative Calculator </title> <script type="text/javascript" src="derivative.js"> </script> <body> <form action="" name=form> <input type=text name=f /> with respects to <input type=text name=vr size=7 /> <input type=button value="Derive!" onClick="main(this.form)" /> <br /> <input type=text name=result value="" /> </form> </body> </html> derivative.js: function main(form) { form.result.value = derive(form.f.value, form.vr.value); } function derive(f, v) { var atom = []; atom["sin(" + v + ")"] = "cos(" + v + ")"; atom["cos(" + v + ")"] = "-sin(" + v + ")"; atom["tan(" + v + ")"] = "sec^(2)(" + v + ")"; atom["sec(" + v + ")"] = "sec(" + v + ")*tan(" + v + ")"; atom["1/(cos(" + v + "))"] = "sec(" + v + ")*tan(" + v + ")"; atom["csc(" + v + ")"] = "-csc(" + v + ")*cot(" + v + ")"; atom["1/(sin(" + v + "))"] = "-csc(" + v + ")*cot(" + v + ")"; atom["cot(" + v + ")"] = "-csc^(2)(" + v + ")"; atom["1/(tan(" + v + "))"] = "-csc^(2)(" + v + ")"; atom["sin^(-1)(" + v + ")"] = "1/sqrt(1 - " + v + "^(2))"; atom["arcsin(" + v + ")"] = "1/sqrt(1 - " + v + "^(2))"; atom["cos^(-1)(" + v + ")"] = "-1/sqrt(1 - " + v + "^(2))"; atom["arccos(" + v + ")"] = "-1/sqrt(1 - " + v + "^(2))"; atom["tan^(-1)(" + v + ")"] = "1/(1 + " + v + "^(2))"; atom["arctan(" + v + ")"] = "1/(1 + " + v + "^(2))"; atom["sec^(-1)(" + v + ")"] = "1/(|" + v + "|*sqrt(" + v + "^(2) - 1))"; atom["arcsec(" + v + ")"] = "1/(|" + v + "|*sqrt(" + v + "^(2) - 1))"; atom["csc^(-1)(" + v + ")"] = "-1/(|" + v + "|*sqrt(" + v + "^(2) - 1))"; atom["arccsc(" + v + ")"] = "-1/(|" + v + "|*sqrt(" + v + "^(2) - 1))"; atom["cot^(-1)(" + v + ")"] = "-1/(1 + " + v + "^(2))"; atom["arccot(" + v + ")"] = "-1/(1 + " + v + "^(2))"; atom["ln(" + v + ")"] = "1/(" + v + ")"; atom["e^(" + v + ")"] = "e^(" + v + ")"; atom["ln(|" + v + "|)"] = "1/(" + v + ")"; atom[v] = "1"; var match = ""; if (new Boolean(atom[f]) == true) { return atom[f]; } else if (f.match(/^[0-9]+$/)) { return ""; } else if (f.match(/([\S]+)([\s]+)\+([\s]+)([\S]+)/)) { match = /([\S]+)([\s]+)\+([\s]+)([\S]+)/.exec(f); return derive(match[1], v) + " + " + derive(match[4], v); } else if (f.match(new RegExp("^([0-9]+)(" + v + ")$"))) { match = new RegExp("^([0-9]+)(" + v + ")$").exec(f); return match[1]; } else if (f.match(new RegExp("^([0-9]+)(" + v + ")\^([0-9]+)$"))) { match = new RegExp("^([0-9]+)(" + v + ")\^([0-9]+)$").exec(f); return String((match[1] * (match[3] - 1))) + v + "^" + String(match[3] - 1); } else { return "?"; } }

  • Regular expression to remove one parameter from query string

    - by Kip
    I'm looking for a regular expression to remove a single parameter from a query string, and I want to do it in a single regular expression if possible. Say I want to remove the foo parameter. Right now I use this: /&?foo\=[^&]+/ That works as long as foo is not the first parameter in the query string. If it is, then my new query string starts with an ampersand. (For example, "foo=123&bar=456" gives a result of "&bar=456".) Right now, I'm just checking after the regex if the query string starts with ampersand, and chopping it off if it does. Example edge cases: Input | Output -------------------------+----------------- foo=123 | (empty string) foo=123&bar=456 | bar=456 bar=456&foo=123 | bar=456 abc=789&foo=123&bar=456 | abc=789&bar=456 Edit OK as pointed out in comments there are there are way more edge cases than I originally considered. I got the following regex to work with all of them: /&foo(\=[^&]*)?(?=&|$)|^foo(\=[^&]*)?(&|$)/ This is modified from Mark Byers's answer, which is why I'm accepting that one, but Roger Pate's input helped a lot too. Here is the full suite of test cases I'm using, and a Perl script which tests them. Input | Output -------------------------+------------------- foo | foo&bar=456 | bar=456 bar=456&foo | bar=456 abc=789&foo&bar=456 | abc=789&bar=456 foo= | foo=&bar=456 | bar=456 bar=456&foo= | bar=456 abc=789&foo=&bar=456 | abc=789&bar=456 foo=123 | foo=123&bar=456 | bar=456 bar=456&foo=123 | bar=456 abc=789&foo=123&bar=456 | abc=789&bar=456 xfoo | xfoo xfoo&bar=456 | xfoo&bar=456 bar=456&xfoo | bar=456&xfoo abc=789&xfoo&bar=456 | abc=789&xfoo&bar=456 xfoo= | xfoo= xfoo=&bar=456 | xfoo=&bar=456 bar=456&xfoo= | bar=456&xfoo= abc=789&xfoo=&bar=456 | abc=789&xfoo=&bar=456 xfoo=123 | xfoo=123 xfoo=123&bar=456 | xfoo=123&bar=456 bar=456&xfoo=123 | bar=456&xfoo=123 abc=789&xfoo=123&bar=456 | abc=789&xfoo=123&bar=456 foox | foox foox&bar=456 | foox&bar=456 bar=456&foox | bar=456&foox abc=789&foox&bar=456 | abc=789&foox&bar=456 foox= | foox= foox=&bar=456 | foox=&bar=456 bar=456&foox= | bar=456&foox= abc=789&foox=&bar=456 | abc=789&foox=&bar=456 foox=123 | foox=123 foox=123&bar=456 | foox=123&bar=456 bar=456&foox=123 | bar=456&foox=123 abc=789&foox=123&bar=456 | abc=789&foox=123&bar=456 Test script (Perl) @in = ('foo' , 'foo&bar=456' , 'bar=456&foo' , 'abc=789&foo&bar=456' ,'foo=' , 'foo=&bar=456' , 'bar=456&foo=' , 'abc=789&foo=&bar=456' ,'foo=123' , 'foo=123&bar=456' , 'bar=456&foo=123' , 'abc=789&foo=123&bar=456' ,'xfoo' , 'xfoo&bar=456' , 'bar=456&xfoo' , 'abc=789&xfoo&bar=456' ,'xfoo=' , 'xfoo=&bar=456' , 'bar=456&xfoo=' , 'abc=789&xfoo=&bar=456' ,'xfoo=123', 'xfoo=123&bar=456', 'bar=456&xfoo=123', 'abc=789&xfoo=123&bar=456' ,'foox' , 'foox&bar=456' , 'bar=456&foox' , 'abc=789&foox&bar=456' ,'foox=' , 'foox=&bar=456' , 'bar=456&foox=' , 'abc=789&foox=&bar=456' ,'foox=123', 'foox=123&bar=456', 'bar=456&foox=123', 'abc=789&foox=123&bar=456' ); @exp = ('' , 'bar=456' , 'bar=456' , 'abc=789&bar=456' ,'' , 'bar=456' , 'bar=456' , 'abc=789&bar=456' ,'' , 'bar=456' , 'bar=456' , 'abc=789&bar=456' ,'xfoo' , 'xfoo&bar=456' , 'bar=456&xfoo' , 'abc=789&xfoo&bar=456' ,'xfoo=' , 'xfoo=&bar=456' , 'bar=456&xfoo=' , 'abc=789&xfoo=&bar=456' ,'xfoo=123', 'xfoo=123&bar=456', 'bar=456&xfoo=123', 'abc=789&xfoo=123&bar=456' ,'foox' , 'foox&bar=456' , 'bar=456&foox' , 'abc=789&foox&bar=456' ,'foox=' , 'foox=&bar=456' , 'bar=456&foox=' , 'abc=789&foox=&bar=456' ,'foox=123', 'foox=123&bar=456', 'bar=456&foox=123', 'abc=789&foox=123&bar=456' ); print "Succ | Input | Output | Expected \n"; print "-----+--------------------------+--------------------------+-------------------------\n"; for($i=0; $i <= $#in; $i++) { $out = $in[$i]; $out =~ s/_PUT_REGEX_HERE_//; $succ = ($out eq $exp[$i] ?

    We have the following XHTML table: <tr class="encabezado"> <th scope="col" width="2%">1</th> <th scope="col" width="2%">2</th> <th scope="col" width="2%">3</th> <th scope="col" width="2%">4</th> <th scope="col" width="2%">5</th> <th scope="col" width="2%">...</th> <th scope="col" width="2%">31</th> </tr> <tr> <th scope="row">Area 1<input name="line_config" type="hidden" value="0,5,50" /></th> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt">...</td> <td class="gantt"> </td> </tr> <tr> <th scope="row">Area 2 <input name="line_config" type="hidden" value="0,0,10" /></th> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt"> </td> <td class="gantt">...</td> <td class="gantt"> </td> </tr> When there is a click over a TD.gantt element, we want jQuery to get the value from input[name='line_config'] tag. We try the following jQuery code, but val() returned 'undefined': $(document).ready(function() { function sum_day(tag, status, column) { var total_day = 0; var index_pos = 0; var values = 0; values = tag.closest('tr').children("input[name='line_config']").val(); alert(values); //Return undefined return total_day; } $('td.gantt').click(function() { var gantt_tag = $('td.preop'); $(this).toggleClass('preop'); sum_day(gantt_tag, 'preop', $(this).index()); }); }); Are we getting right the value way? If anyone can help us, we appreciate... =)

  • How to prevent jQuery FancyBox from closing immediately after submit?

    - by Dimitri
    Hi! I'm loading an inline registration form in a FancyBox from jQuery. However after submitting the form, the box immediately closes while there is some feedback that I want to show the user in the FancyBox itself. This feedback is generated on the server side and is printed in the FancyBox. How can I make the box only closing when their is no feedback anymore? I was thinking about using ajax to just refresh the FancyBox itself and not the whole page after refreshing. But I just can't figure out how this ajax $.ajax({type, cache, url, data, success}); works... Also it seems like there's no reaction from the 'submit bind' in the javascript. I hope someone can help me with this problem. I paste my code below. If any questions, plz ask.. Thx in advance! This is the javascript: <script type="text/javascript"> $(document).ready(function() { $("#various1").fancybox({ 'transitionIn' : 'none', 'transitionOut' : 'none', 'scrolling' : 'no', 'titleShow' : false, 'onClosed' : function() { $("#registration_error").hide(); } }); }); $("#registration_form").bind("submit", function() { if ($("#registration_error").val() != "Registration succeeded!") { $("#registration_error").show(); $.fancybox.resize(); return false; } $.fancybox.showActivity(); $.ajax({ type : "POST", cache : false, url : "/data/login.php", data : $(this).serializeArray(), success : function(data) { $.fancybox(data); } }); return false; }); This is the inline form that I show in the FancyBox: <div style="display: none;"> <div id="registration" style="width:227px;height:250px;overflow:auto;padding:7px;"> <?php echo "<p id=\"registration_error\">".$feed."</p>"; ?> <form id="registration_form" action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post"> <p> <label for="username">Username: </label> <input type="text" id="login_name" name="username" size="30" /> </p> <p> <label for="password">Password: </label> <input type="password" id="pass" name="pw" size="30" /> </p> <p> <label for="repeat_password">Repeat password: </label> <input type="password" id="rep_pass" name="rep_pw" size="30" /> </p> <p> <input type="submit" value="Register" name="register" id="reg" /> </p> <p> <em></em> </p> </form> </div> </div>

  • [python] voice communication for python help!

    - by Eric
    Hello! I'm currently trying to write a voicechat program in python. All tips/trick is welcome to do this. So far I found pyAudio to be a wrapper of PortAudio. So I played around with that and got an input stream from my microphone to be played back to my speakers. Only RAW of course. But I can't send RAW-data over the netowrk (due the size duh), so I'm looking for a way to encode it. And I searched around the 'net and stumbled over this speex-wrapper for python. It seems to good to be true, and believe me, it was. You see in pyAudio you can set the size of the chunks you want to take from your input audiobuffer, and in that sample code on the link, it's set to 320. Then when it's encoded, its like ~40 bytes of data per chunk, which is fairly acceptable I guess. And now for the problem. I start a sample program which just takes the input stream, encodes the chunks, decodes them and play them (not sending over the network due testing). If I just let my computer idle and run this program it works great, but as soon as I do something, i.e start Firefox or something, the audio input buffer gets all clogged up! It just grows and then it all crashes and gives me an overflow error on the buffer.. OK, so why am I just taking 320 bytes of the stream? I could just take like 1024 bytes or something and that will easy the pressure on the buffer. BUT. If I give speex 1024 bytes of data to encode/decode, it either crashes and says that thats too big for its buffer. OR it encodes/decodes it, but the sound is very noisy and "choppy" as if it only encoded a tiny bit of that 1024 chunk and the rest is static noise. So the sound sounds like a helicopter, lol. I did some research and it seems that speex only can convert 320 bytes of data at time, and well, 640 for wide-band. But that's the standard? How can I fix this problem? How should I construct my program to work with speex? I could use a middle-buffer tho that takes all available data to read from the buffer, then chunk this up in 320 bits and encode/decode them. But this takes a bit longer time and seems like a very bad solution of the problem.. Because as far as I know, there's no other encoder for python that encodes the audio so it can be sent over the network in acceptable small packages, or? I've been googling for three days now. Also there is this pyMedia library, I don't know if its good to convert to mp3/ogg for this kind of software. Thank in in advance for reading this, hope anyone can help me! (:

  • Symfony sfDoctrineGuard plugin sfGuardUser module

    - by Joe Mc
    When using sfDoctrineGuard plugin, it automatically generates the backend administration functionality where I can edit users of the system and assign them permissions. So I visit http://.../backend_dev.php/sf_guard_user/:id/edit where I am presented with the user's information including the available permissions to select. By default the permissions are shown as a multiple select box, HTML follows: <select name="sf_guard_user[permissions_list][]" multiple="multiple" id="sf_guard_user_permissions_list"> <option value="1">Permission1</option> <option value="2">Permission2</option> <option value="3">Permission3</option> <option value="4">Permission4</option> </select> What I would prefer is a list of checkboxes. So I searched around and found that if I add the option "expanded" set to true to the following code: 'permissions_list' => new sfWidgetFormDoctrineChoice(array('multiple' => true, 'model' => 'sfGuardPermission', 'expanded' => true,)), The code is part of this file: lib/form/doctrine/sfDoctrineGuardPlugin/base/BasesfGuardUserForm.class.php. I don't think I should've edited this file (potential for changes to be overwritten should sfDoctrineGuard ever be re-installed) but couldn't think of another way to make it work. The generated HTML is as follows: <ul class="checkbox_list"> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="1" id="sf_guard_user_permissions_list_1" />&nbsp;<label for="sf_guard_user_permissions_list_1">Permission1</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="2" id="sf_guard_user_permissions_list_2" />&nbsp;<label for="sf_guard_user_permissions_list_2">Permission2</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="3" id="sf_guard_user_permissions_list_3" />&nbsp;<label for="sf_guard_user_permissions_list_3">Permission3</label></li> <li><input name="sf_guard_user[permissions_list][]" type="checkbox" value="4" id="sf_guard_user_permissions_list_4" />&nbsp;<label for="sf_guard_user_permissions_list_4">Permission4</label></li> </ul> What I need to do now is split up the permissions based on their prefix. For example if I had permissions named user_action1, user_action2, file_action1, file_action2, they would display like: User checkbox (custom label) Action One checkbox Action Two File checkbox (custom label) Action One checkbox Action Two but have no idea where to start with this. It would be easy if there was a template to edit but since I'm dealing with the Forms framework it is my understanding that the templates are generated on the fly - I can see them in my symonfy cache folder. How would I go about this? I started writing my own sfWidgetFormDoctrineChoicePermission class that extends the same class as sfWidgetFormDoctrineChoice but am struggling to edit the rendering functions correctly for the desired output. Is this the correct way to go about this work? I also need to integrate my sfGuardUserProfile model into the edit user page (same as above), I read somwhere that editing the generator.yml file for the sfGuardUser plugin module and simply adding the field names from the sfGuardUserProfile table would make it work, but sadly it doesn't. Any help with any of my queries would be appreciated. Thanks

  • using PixelBender to double the size of a bitmap

    - by jedierikb
    I have a performance question about pixel bender. I want to enlarge many BitmapData (double their size into new BitmapData). I was doing this with as3, but wanted to use pixel bender to get better performance. On my machines, I get great comparative performance out of many pixel bender demonstrations. To my surprise (or bad coding / understanding), I am getting much worse performance out of pixel bender -- 2 seconds to do 3000 scalings vs .5 seconds! I expected to get at least the same performance as as3. What am I doing wrong? I got the straightforward pixel bender code here (and it is included below for easy reference). package { import aCore.aUtil.timingUtils; import flash.display.BitmapData; import flash.display.Shader; import flash.display.ShaderJob; import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.Event; import flash.geom.Matrix; public class flashFlash extends Sprite { [Embed ( source="pixelbender/bilinearresample.pbj", mimeType="application/octet-stream" ) ] private static var BilinearScaling:Class; public function flashFlash( ):void { stage.align = StageAlign.TOP_LEFT; stage.scaleMode = StageScaleMode.NO_SCALE; addEventListener( Event.ENTER_FRAME, efCb, false, 0, true ); } private function efCb( evt:Event ):void { removeEventListener( Event.ENTER_FRAME, efCb, false ); traceTime( "init" ); var srcBmd:BitmapData = new BitmapData( 80, 120, false, 0 ); var destBmd:BitmapData = new BitmapData( 160, 240, false, 0 ); var mx:Matrix = new Matrix( ); mx.scale( 2, 2 ); for (var i:uint = 0; i < 3000; i++) { destBmd.draw( srcBmd, mx ); } traceTime( "scaled with as3" ); // create and configure a Shader object var shader:Shader = new Shader( ); shader.byteCode = new BilinearScaling( ); shader.data.scale.value = [2]; shader.data.src.input = srcBmd; for (var j:uint = 0; j < 3000; j++) { var shaderJob:ShaderJob = new ShaderJob( ); shaderJob.shader = shader; shaderJob.target = destBmd; shaderJob.start( true ); } traceTime( "scaled with pixel bender bilinearresample.pbj" ); } private static var _lastTraceTime:Number = new Date().getTime(); public static function traceTime( note:String ):Number { var nowTime:Number = new Date().getTime(); var diff:Number = (nowTime-_lastTraceTime); trace( "[t" + diff + "] " + note ); _lastTraceTime = nowTime; return diff; } } } And the pixel bender code: <languageVersion : 1.0;> kernel BilinearResample < namespace : "com.brooksandrus.pixelbender"; vendor : "Brooks Andrus"; version : 1; description : "Resizes an image using bilinear resampling.
