  • Creating an independent draw thread using pthreads (C++)

    - by sagekilla
    Hi all, I'm working on a graphical application which looks something like this: while (Simulator.simulating) { Simulator.update(); InputManager.processInput(); VideoManager.draw(); } I do this several times a second, and in the vast majority of cases my computation will be taking up 90 - 99% of my processing time. What I would like to do is take out the processInput and draw functions and have each one run independently. That way, I can have the input thread always checking for input (at a reasonable rate), and the draw thread attempting to redraw at a given frame rate. My issue is I'm not sure how I can properly do this. How would I properly initialize my pthread_t and associated pthread_attr_t so that the thread runs without blocking what I'm doing? Any help or even a link is appreciated, thanks!

  • Turn a Computer Power Supply into a Desktop Power Supply

    - by Jason Fitzpatrick
    If you’re looking for a desktop power supply for your electronics workbench, this tutorial video shows you how to turn a computer PSU into a desktop power supply. In the above video the guys at JumperOneTV show us how to make a desktop power supply. As an addendum to the video; they note in the comments section on the YouTube video that they were wearing gloves for the drilling and that they did a very thorough job cleaning out any loose metal shavings with an air compressor. If you wanted to play it even safer (and you should!) you would remove the circuit board from the enclosure before doing any drilling.

  • Myfaces extensionfilter overriding renderkit? (Tree2 component)

    - by Mike
    I've pulled in the tree2 component (from Tomahawk 1.1.9). Had used the simpler Tree component on previous projects, and this one just looks a bit nicer. Running on websphere 6.1.x and set the server side flag that's needed (com.ibm.ws.webcontainer.invokefilterscompatibility=true) and set the extensionfilter accordingly. Everything's good, and works as expected. Here's the issue: - on a page being included on this one (just some typical footer type info with NO myfaces widgets), there's some embedded html that's getting flagged with warnings in the systemout console). These look like org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 475. Surroundings: 'span id="tile:footr:viewFragm'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 479. Surroundings: 'a id="tile:footr:viewFragment'. org.apache.myfaces.renderkit.html.util.ReducedHTMLParser parse Invalid tag found: unexpected input while looking for attr name or '/' at line 492. Surroundings: 'a id="tile:footr:viewFragment'. The problem isn't necessarily with the html (which should be cleaned up regardless :-). IF I don't include myfaces, I don't get these warning messages with the default ibm jsf renderer (using jsf 1.1 still). Obviously, IBM's implementation is a bit more lax than myFaces. The page has nothing to do with myfaces at all. The reason for needing the extension filter is that it needs (for the Tree2 anyways, I know it does more for file upload) to intercept requests and then stick some .js includes on the page. Investigated this a bit, and I've included this filter in my web.xml, but it is NO longer fronting the faces servlet. So, the filter is instantiated at startup, but is never executed. Since the filter isn't in place, I've had to hard code in the includes for the 2 .js files into my page Now, the tree2 gets rendered properly, AND I'm not getting the warnings from above, because with the extentionfilter not being called, its using the IBM renderkit ;-) I'm a bit concerned that when the extension filter is in place, everything is being rendered by myFaces, rather than IBM's renderkit (i.e. All I want is myfaces/tomahawk to render the tree2 only, and let the ri do everything else) Can anyone confirm this? When you use myfaces/tomahawk, is it doing all the rendering for the whole application, or just the page any tomahawk widget is on? Thanks for any thoughts on this mike

  • Binding multiple events in jQuery

    - by Lachlan McDonald
    I have a custom jQuery plugin which binds a change event to a form element, in this case some input elements. The change event is used to indicate to some other components that a change has taken place. This works as it should. However, I've come across the need to bind an additional change event to the same input elements -- so that additional components can act on the event. I don't wish to replace the plugin's change, simply run an additional function afterwards. Is there any way to bind multiple events in jQuery, or, what is the best method for accomplishing this?

  • Pair programming tools that are not remote

    - by JonathanTech
    I am currently in a job where we practice serious pair programming on windows machines. We both have a set of keyboards, mice, and we have two monitors, which works well for switching who's the driver really easy, but there are some points in the session that I would like to start writing tests at the same time that my pair is writing implementation. I am wondering if there is any program that would allow me to have effectively two cursors and keyboard focuses on the same computer. If they don't exist then I am willing to experiment with my own solution, but I would like input as to how to best accomplish this. I am most familiar with .Net 3.5 technologies, but I also know Java and am willing to learn C++ to solve this problem. If I was creating the solution myself I would go down the road of being able to grab the input of one hardware device (i.e. a specific mouse that's installed) and prevent Windows from moving the pointer, and instead move my own programs pointer independently.

  • How to detect Javascript pop-up notifications in WatiN?

    - by Ian P
    I have a, what seems to be, rather common scenario I'm trying to work through. I have a site that accepts input through two different text fields. If the input is malformed or invalid, I receive a Javascript pop-up notification. I will not always receive one, but I should in the event of (like I said earlier) malformed data, or when a search result couldn't be found. How can I detect this in WatiN? A quick Google search produced results that show how to click through them, but I'm curious as to whether or not I can detect when I get one? In case anyone is wondering, I'm using WatiN to do some screen scraping for me, rather than integration testing :) Thanks in advance! Ian

  • Custom types in OpenCL kernel

    - by Studer
    Is it possible to use custom types in OpenCL kernel like gmp types (mpz_t, mpq_t, …) ? To have something like that (this kernel doesn't build just because of #include <gmp.h>) : #include <gmp.h> __kernel square( __global mpz_t* input, __global mpz_t number, __global int* output, const unsigned int count) { int i = get_global_id(0); if(i < count) output[i] = mpz_divisible_p(number,input[i]); } Or maybe does OpenCL already have types that can handle large numbers ?

  • Create a Slide Show in Windows 7 Media Center

    - by DigitalGeekery
    Are you looking for a nice way to create and display a slide show from your photo collection? Today we’ll show you how to create a slide show, how to add music to it, and watch it from the comfort of your couch in Windows 7 Media Center. Create Slide Show Launch Windows 7 Media Center and click on the Picture Library tile found under Pictures and Videos.   In the Pictures Library, scroll across to slide shows and click on Create Slide show.   Enter a name for the slide show and click Next.   If you are using a Windows Media Center remote, click on the OK button to bring up the onscreen keyboard. Use the directional buttons to navigate across the keyboard and press OK to select each letter. Click Done when finished. Select Picture Library and click Next. Select the pictures to include in your slide show. If using a remote, navigate through the images and press OK to select. If you are using a mouse, simply click on the selections. When you are finished, click Next.    Now, we can review and edit the slide show. Click the up or down pointing arrows to move pictures up and down in the order.  (more intuitive titles would be helpful in this case as opposed to the randomly generated titles in the example below) If you are finished, click Create. You can also choose to go back and add music to your slide show. (or even more pictures) We’ll take a look at adding some music in our example. Click on the Add More button.   Add Music to Your Slide Show Here we’ll select Music Library to add a song. Click Next.   You’ll now be able to browse your Music Library to select songs for your slide show. Select your songs and click Next.   When you are finished adding Music and Pictures click Create.   Once your slide show is saved, you can play it any time by going to clicking on slide shows in the Picture Library, then selecting the slide show title. Select play slide show when you’re ready to enjoy your new production.   If you ever want to edit or delete the slide show, select it in the Picture Library, and scroll to Actions. You’ll see those option under additional commands. You have the option to Edit Slide Show, Burn a CD/DVD, or Delete. Editing Slide Show Settings Within Media Center, go to Tasks… Click on Pictures…   Then choose Slide Shows. From the Slide Show settings you have the option to Show pictures in random order, Show picture information, Show song information, and Use Pan and zoom effect. You can also adjust the length of time to display each picture, and change the background color. Be sure to click Save to apply and changes before exiting. If you choose to show picture information, the picture title, date, and star rating will be displayed in the top right.   If your slide show is accompanied by music and you choose to show song information, you will get a translucent overlay for a few seconds at the beginning of each song to indicate the song, album, and artist. One of the really cool things about creating a slide show in Windows 7 Media Center is you can complete the entire process using just a Media Center remote. Can’t get enough slide shows?

  • Can't reboot netbook with any of the reboot parameters

    - by Delan Azabani
    I have a Sony VPCW218AG netbook that I've dual-booted with Ubuntu 10.10. Unlike the preinstalled Windows 7, Ubuntu will not reboot on this computer. Rebooting from Gnome, using the reboot command and SysRq+REISUB all don't work; they end hanging with a blank screen. I have read that Atom netbooks don't have a keyboard controller and therefore the default reboot method, kbd, won't work. I have actually tried all ten reboot= parameters listed here; none of them work. I have also tried disabling ACPI with noacpi acpi=off for each one; that didn't help either. Are there any other things I can try to fix the rebooting problem?

  • WCF Webservices and FaultContract - Client's receiving SoapExc insted of FaultException<TDetails>

    - by Alessandro Di Lello
    Hi All, i'm developing a WCF Webservice and consuming it within a mvc2 application. My problem is that i'm using FaultContracts on my methods with a custom FaultDetail and i'm throwing manyally the faultexception but when the client receive the exception , it receives a normal SoapException instead of my FaultException that i throwed from the service side. Here is some code: Custom Fault Detail Class: [DataContract] public class MyFaultDetails { [DataMember] public string Message { get; set; } } Operation on service contract: [OperationContract] [FaultContract(typeof(MyFaultDetails))] void ThrowException(); Implementation: public void ThrowException() { var details = new MyFaultDetails { Message = "Exception Test" }; throw new FaultException<MyFaultDetails >(details , new FaultReason(details .Message), new FaultCode("MyFault")); } Client side: try { // Obv proxy init etc.. service.ThrowException(); } catch (FaultException<MyFaultDetails> ex) { // stuff } catch (Exception ex) { // stuff } What i expect is to catch the FaultException , instead that catch is skipped and the next catch is taken with an exception of type SoapException. Am i missing something ? i red a lot of threads about using faultcontracts within wcf and what i did seems to be good. I had a look at the wsdl and xsd generated and they look fine. here's a snippet regarding this method: <wsdl:operation name="ThrowException"> <wsdl:input wsaw:Action="http://tempuri.org/IAnyJobService/ThrowException" message="tns:IAnyJobService_ThrowException_InputMessage" /> <wsdl:output wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionResponse" message="tns:IAnyJobService_ThrowException_OutputMessage" /> <wsdl:fault wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionAnyJobServiceFaultExceptionFault" name="AnyJobServiceFaultExceptionFault" message="tns:IAnyJobService_ThrowException_AnyJobServiceFaultExceptionFault_FaultMessage" /> </wsdl:operation> <wsdl:operation name="ThrowException"> <soap:operation soapAction="http://tempuri.org/IAnyJobService/ThrowException" style="document" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> <wsdl:fault name="AnyJobServiceFaultExceptionFault"> <soap:fault use="literal" name="AnyJobServiceFaultExceptionFault" namespace="" /> </wsdl:fault> </wsdl:operation> Any help ?

  • Implementation of ECC in Java

    - by Rookie_22
    While trying to encrypt a given input using Elliptic Curve Cryptography in Java I'm using the following algorithms for generating the cipher and the key: KeyPairGenerator g = KeyPairGenerator.getInstance("ECDSA"); Cipher cipher = Cipher.getInstance("ECIES"); Now as expected, the cipher isn't accepting the keys generated by the ECDSA algorithm. I get the error as - must be passed IE key. I searched for the ciphers being supported by these 2 methods here: http://java.sun.com/javase/6/docs/technotes/guides/security/StandardNames.html#Cipher Unfortunately no else algo is supported for ECC. Has anyone used ECC generated keys to encrypt/decrypt an input? Which algo should I use for both so that they don't clash with each other?

  • Set default form textfield value (webbrowser control/DOM Javscript)

    - by Khou
    Hi I would like my application to load a webpage and set default the form textfield value a predefine value. Requirements: -The application is a windows form, it is to use the web browser control, to load a web page. -Textfield values are define by within the application. -When textfield on the webpage matches the applications predefined elements, the predefine fixed value is set and can not be changed by the end user. Example If my application defines element "FirstName" equal to value "John", the text field for value for element "FirstName" will always equal "John" and this value can not be changed by the end user. Below is html/javascript code to perform this functionality, now how do I implement this in a windows form? (without having to modify the loaded webpage source code (if possible).

  • Spring MVC defaultValue for Double

    - by mlathe
    Hi All, I'm trying to build a controller like this: @RequestMapping(method = {RequestMethod.GET}, value = "/users/detail/activities.do") public View foo(@RequestParam(value = "userCash", defaultValue="0.0") Double userCash) { System.out.println("foo userCash=" + userCash); } This works fine: http://localhost/app/users/detail/activities.do?userCash=123& but in this one userCash==null despite the default value http://localhost/app/users/detail/activities.do?userCash=& From some digging it seems like the first one works b/c of a Editor binding like this: binder.registerCustomEditor(Double.class, new CustomNumberEditor(Double.class, false)); The trouble is that the second param (ie false) defines whether blank values are allowed. If i set that to true, than the system considers the blank input as valid so i get a null Double class. If i set it to false then the system chokes on the blank input string with: org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'double'; nested exception is java.lang.NumberFormatException: empty String Does anyone know how to get the defaultValue to work for Doubles?

  • Rails: radio button selection for nested forms objects

    - by satynos
    I have the following form for photo_album which uses the nested forms feature of the Rails in saving the photos while updating the photo_album. And having trouble with the selection of radio button value. I want only one of the photos be able to select as the album cover, but due to the way rails produces form element ids and names, I am able to select all of the photos as album covers. Is there any workaround? <% form_for @photo_album do |f| %> <%= f.error_messages %> <% @photo_album.photos.each do |photo| %> <% f.fields_for :photos, photo do |photo_fields| %> <p> <%= image_tag url_for_image_column(photo, "data", :thumb) %> </p> <p> <%= photo_fields.label :title %> <%= photo_fields.text_field :title %> </p> <p> <%= photo_fields.label :body %> <%= photo_fields.text_area :body %> </p> <p> <%= photo_fields.radio_button :cover, "1" %> <%= photo_fields.label :cover, 'Album Cover', :class => 'option' %> <%= photo_fields.check_box :_delete %> <%= photo_fields.label :_delete, 'Delete', :class => 'option' %> </p> <% end %> <% end %> <p> <%= f.submit @photo_album.new_record? ? 'Create' : 'Update' %> </p> <% end %> And following is the html produced by rails (which is part of the problem) for radio buttons: <p> <input type="radio" value="1" name="photo_album[photos_attributes][0][cover]" id="photo_album_photos_attributes_0_cover_1"/> <label for="photo_album_photos_attributes_0_cover" class="option">Album Cover</label> <input type="hidden" value="0" name="photo_album[photos_attributes][0][_delete]"/><input type="checkbox" value="1" name="photo_album[photos_attributes][0][_delete]" id="photo_album_photos_attributes_0__delete"/> <label for="photo_album_photos_attributes_0__delete" class="option">Delete</label> </p>

  • Re-setting CSS code for form buttons

    - by WebDevHobo
    I used a CSS reset to reset some commonly-used items. The code is this: html, body, div, h1, h2, h3, h4, ul, ol, li, form, input, fieldset, textarea { margin: 0; padding: 0; border: 0; font-size: 100%; } ul {list-style: none outside none;} img, fieldset {border: 0;} h1, h2, h3, h4 {font-weight: normal;} em {font-style: italic;} strong {font-weight: bold;} I know there's YUI and Meyer's reset, but I use this one. Now, the problem I'm experiencing is that I can't get the submit buttons to look normally again. I could ofcourse remove the input from the list and be done with it, but I'd like to know how to get it back, since I might need that in the future.

  • How to create a UDF that takes a query string and returns the query's resultset

    - by Martin
    I want to create a stored procedure that takes a simple SELECT statement and return the resultset as a CSV string. So the basic idea is get the sql statement from user input, run it using EXEC(@stmt) and convert the resultset to text using cursors. However, as SQLServer doesn't allow: select * from storedprocedure(@sqlStmt) UDF with EXEC(@sqlStmt) so I tried Insert into #tempTable EXEC(@sqlStmt), but this doesn't work (error = "invalid object name #tempTable"). I'm stuck. Could you please shed some light on this matter? Many thanks EDIT: Actually the output (e.g CSV string) is not important. The problem is I don't know how to assign a cursor to the resultset returned by EXEC. SP and UDF do not work with Exec() while creating a temp table before inserting values is impossible without knowing the input statement. I thought of OPENQUERY but it does not accept variables as its parameters.

  • CSS / HTML centering a textbox

    - by Robert
    This should be easy but its proving difficult... My element I want centred is exactly this <input type="text"> I don't want the text centred, just the text box within the outer div. This is my attempt which is not working <div class ="temp123"> <input type="text" /> </div> Where: .temp123 { margin: 0 auto; margin-left: auto; margin-right: auto; } The text box remains on the left. The outer div has a fixed with of 300px and itself is centered using margin: 0 auto;

  • Why Ubuntu Server asks to insert a CD-ROM when installed from PXE?

    - by MainMa
    I set up a PXE server which hosts both Ubuntu Desktop and Ubuntu Server. Ubuntu Desktop is installed successfully from PXE. Ubuntu Server seems to successfully load vmlinuz and initrd.gz, asks for the language, then the location, then the keyboard layout, and finally complains that it can't mount the CD-ROM: The content of /var/lib/tftpboot/pxelinux.cfg/default is the following: default ubuntu-installer/amd64/boot-screens/vesamenu.c32 menu title Ubuntu setup label ubuntu-14.04-desktop-amd64 menu label ubuntu-14.04-desktop-amd64 kernel ubuntu-14.04-desktop-amd64/vmlinuz.efi append initrd=ubuntu-14.04-desktop-amd64/initrd.lz root=/dev/nfs boot=casper netboot=nfs nfsroot=192.168.1.41:/exports/ubuntu-14.04-desktop-amd64 splash -- label ubuntu-14.04-server-amd64 menu label ubuntu-14.04-server-amd64 kernel ubuntu-14.04-server-amd64/vmlinuz append initrd=ubuntu-14.04-server-amd64/initrd.gz root=/dev/nfs boot=install netboot=nfs nfsroot=192.168.1.41:/exports/ubuntu-14.04-server-amd64 splash -- What explains the fact that it requests the CD-ROM and how to avoid it?
