  • Account verification Yelp style, how is it more "secure" than traditional verification?

    - by Chad
    For business owners to "take control" of their business page on Yelp, they register for it. The Yelp system performs a telephone call-back. From watching to the video here, it sounds like a telephone version of what we all typically do - e-mail check. For e-mail check, it basically goes like this: User registers verify e-mail sent they click link inside verify e-mail site verifies Here's Yelp's: User registers verify screen shown with code Yelp calls user user enters code site verifies It's essentially the same thing, via phone. Is there any reason you can see why this method is better than the e-mail method?

  • Database design in blogging systems

    - by Peter
    As a learning exercise I'm trying to put myself a blogging system. The goal is to code something that will let me create multiple blogs, like blogger.com or wordpress.com, but much simplified. I would like to ask you, what do you think is best database design for this type of script. Is it better to have one big table, containing posts from all blogs of all users (like friendfeed) or would it be better to create separate table for each blog's posts? Big thanks in advance for your help, Peter.

  • UiElement based on another class

    - by plotnick
    I placed a control into a grid. let's say the control is derived from public class 'ButBase' which is derived in its turn from System.Windows.Controls.Button. The code normally compiles and app works just fine. But there's something really annoying. When you try to switch to xaml-design tab it will say 'The document root element is not supported by the visual designer', which is normal and I'm totally okay with that, but the thing is, that all the xaml code is underlined and VS2010 says: 'Cannot create an instance of ButBase' although still normally compiles and able to run. I've tried the same code in VS2008, it said that needs to see a public parameterless constructor in the ButBase, and even after I put one it showed the same error. What do I miss here?

  • Linux: page faults and network filesystems

    - by Alex B
    If a Linux system runs out of physical memory, does it drop inactive executable code pages? I assume the answer is yes, since there is no reason to keep them in swap, so they are simply discarded and re-loaded if necessary (as far as I know, that's what FreeBSD does). If the above is true for Linux, my question is, how does it handle executables run from network filesystems (e.g. NFS)? Does it go and fetch executable pages over the network if there is a page fault?

    The sendkeys code below works well for Notepad but it doesn't work for Calculator. What is the problem? (It's another problem compared to what I sent here http://stackoverflow.com/questions/2604486/c-sendkeys-problem) [DllImport("user32.dll", CharSet = CharSet.Unicode)] public static extern IntPtr FindWindow(string lpClassName,string lpWindowName); [DllImport("User32")] public static extern bool SetForegroundWindow(IntPtr hWnd); private void button1_Click(object sender, EventArgs e) { IntPtr calculatorHandle = FindWindow("SciCalc", "Calculator"); //IntPtr calculatorHandle = FindWindow("Notepad", "Untitled - Notepad"); if (calculatorHandle == IntPtr.Zero) { MessageBox.Show("Calculator is not running."); return; } SetForegroundWindow(calculatorHandle); System.Threading.Thread.Sleep(1000); SendKeys.SendWait("111*11="); //SendKeys.SendWait("{ENTER}"); //cnt++; SendKeys.Flush(); }

  • How to build gnu `libiconv` on & for windows?

    - by claws
    Hello, I want to build a static library (*.LIB file) GNU libiconv on windows to be used with other libraries in Visual C++. Other libraries I'm using are built with "MultiThreaded DLL" (/MD) Runtime option. So, I need to build libiconv with the same option. Problem is the libiconv uses GNU build system and I want to compile with /MD option. You can see the source structure of libiconv here: http://cvs.savannah.gnu.org/viewvc/libiconv/?root=libiconv Actually, Mr. Zlatkovic maintains the windows port of GNU libiconv for libxml2 you can see them here: ftp://xmlsoft.org/libxml2/win32/iconv-1.9.2.win32.zip ftp://xmlsoft.org/libxml2/win32/iconv-1.9.2.win32.zip I cannot use his port. I need to build from the latest version of libiconv-1.13. I wonder how this guy has ported it? Can some one please tell me how to build *.lib from this and compile it using MSVC?

  • Value of text box disapears - binding viewmodel to a tab (content control)

    - by Eli Perpinyal
    Based on the MVVM example by Josh Smith, I have implemented the multi tab option which binds to a different tab to a different view model using a simple datatemplate that binds a viewmodel to a view. <DataTemplate DataType="{x:Type fixtureVM:SearchViewModel}"> <SearchVw:SearchView/> </DataTemplate> The issue that I'm having, is when I switch tabs and then switch back again, the value in the textbox disappears. When I bind the Text in the textbox to a value in the ViewModel it does not disappear. This is fine, and I can overcome this but I am having another issue for example with the position of the scroll bar in a grid disappearing once the tab has lost focus. Why is the value disappearing? I'm assuming it is a WPF sub system task that cleans up resources!? how can I avoid this? I also feel it might be slowing down my app.

  • ASP.NET Session State Error only on default document

    - by schmidty
    I have a site where when accessing via site.com/default.aspx everything is fine, however when accessing via site.com/ I get a session error as follows: "Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration." I have confirmed that default.aspx is the highest priority default document and that it is the page being loaded. However why is this session error only occurring when accessing via the default document? The server is 2008 R2 and IIS 7.5.

  • Android drawing cache

    - by Seva Alekseyev
    Please explain how does the drawing cache work in Android. I'm implementing a custom View subclass. I want my drawing to be cached by the system. In the View constructor, I call setDrawingCacheEnabled(true); Then in the draw(Canvas c), I do: Bitmap cac = getDrawingCache(); if(cac != null) { c.drawBitmap(cac, 0, 0, new Paint()); return; } Yet the getDrawingCache() returns null to me. My draw() is not called neither from setDrawingCacheEnabled(), nor from getDrawingCache(). Please, what am I doing wrong?

  • How to get --detect-branches to work with git-p4?

    - by Michael Brennan
    My p4 repository has a structure similar to: //depot/project/branch1 //depot/project/branch2 //depot/project/branch3 ... etc However, when I use git-p4 to clone "project", all 3 branches are not considered as branches and all get cloned into the single master branch. This is how I'm invoking git-p4: git-p4 clone --detect-branches //depot/project I was expecting git-p4 to create a git database for "project" with three branches, and the root of the project would be mapped to the portion of the path after the branch name (for example: if //depot/project/branch1 has a subdirectory called "lib" (//depot/project/branch1/lib) then my local file system should be something like /git_project/lib with 3 git branches). Is what I'm expecting wrong? Am I invoking git-p4 incorrectly?

  • How does UIImage work in low-memory situations?

    - by kubi
    According to the UIImage documentation: In low-memory situations, image data may be purged from a UIImage object to free up memory on the system. Does anyone know how this works? It appears that this process is completely transparent and will occur in the background with no input from me, but I can't find any definitive documentation one way or the other. Second, will this data-purge occur when the image is not loaded by me? (I'm getting the image from UIImagePicker). Here's the situation: I'm taking a picture with the UIImagePickerController and and immediately taking that image and sending it to a new UIViewController for display. Sending the raw image to the new controller crashes my app with memory warnings about 30% of the time. Resizing the image takes a few moments, time that I'd rather not spend if there's a 3rd option available to me.

  • Removing a specific XML node in TIBCO BusinessWorks

    - by sangretu
    I have a "global variable" XML schema in TIBCO BusinessWorks. It's simpler than it looks - basically just a single repeatable node. Image: Tibco globals. (old URL redacted) Various processes in the system can update this list. Checking to see if they are listed is easy: $GetVariable/subscriber-list/subscriber = $_processContext/ns:ProcessContext/ProcessId Adding themselves to the list is pretty easy too, using a Set Variable activity (see bottom half of image) But how can a process remove itself from the list? I'm sure there's a type of mapping I can use to filter out the node I want and let the rest through?

  • SEO friendly CMS with user profile functionality

    - by kjgilla
    My company has a project to create a magazine style site with user profile functionality. We need: CMS for the article publishing. SEO Friendly urls. Commenting capability for the published articles. User profile system with limited social networking functionality (friends,friend messages,blog,account tweaking/personalization, article commenting) My area of expertise is asp.net, particularly MVC. I have read similar posts on this site regarding CMS with MVC and I'm surveying the landscape (N2, Kooboo, MvcCms, etc). What I am really interested in knowing is whether there are any platforms out there (WAMP or LAMP) that provide this functionality out of the box. I may be willing to go the LAMP route if it requires little development work. If I have to crack open any code then it probably needs to be .net unless there are compelling reasons to go another route.

  • Tricks to avoid losing motivation?

    - by AareP
    Motivation is a tricky thing to upkeep. Once I thought that ambitious projects will keep programmer motivated, and too simple tasks will hinder his motivation. Now I have plenty of experience with small and large projects, desktop/web/database programming, c++/c#/java/php languages, oop/non-oop paradigms, day-job/free-time programming.. but I still can't answer the question of motivation. Which programming tasks I like, and which don't? It seems to depend on too many variables. One thing remains constant though. It's that starting everything from scratch is always more motivating than extending some existing system. Unfortunately it's hard to use this trick in productive programming. :) So my question is, what tricks programmer can use to stay motivated? For example should we use pen and paper as much as possible, in order not to get fed up with monitor and keyboard?

  • What does "Unatuthorized zone" mean when browsing xsd files with Visual Studio 2010?

    - by starskythehutch
    When I open up an xsd file that includes other xsd files, all of the included files are added to a section called "Unauthorized zone". Visual Studio highlights the element and gives the following error when trying to resolve the schemaLocation attribute: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. I've read the following blog post, but I'm not familiar enough with xsd yet to fully understand it. Can anyone explain why this is happening or point me to a good resource that can help?

  • 301 versus inline rewrites

    - by Kristoffer S Hansen
    I'm in the process of adding 'pretty' URLs to an existing CMS, the menu is auto generated and the new 'pretty' URLs are to be handled independently as a seperate module. The auto-generated menu allways has URLs that look like this index.php?menu_id=n which ofcourse we would like to see as eg. /news or /products I'm currently at the point where I have to decide if I'm going to rewrite all output of the current system or simply put in a hook where I redirect to the 'pretty' URL. To put it differently, should i connect to the database, fetch all 'pretty' URLs, run through the existing output from WYSIWYG's, news modules, forums etc. and do some str_replace or other string manipulation (which I think would be a rather tedious and boring process), or should I simply hook in and throw a 301 redirecting index.php?menu_id=3 to /news will Google (or other search engines) penalize me for having 301's in the menus?

  • Javascript onbeforeunload Issue

    - by Nik
    Alright, I have an issue with the following code. What happens is when a user closes their browser, it should prompt them to either click OK or click CANCEL to leave the page. Clicking OK would trigger a window.location to redirect to another page for user tracking (and yes, to avoid flame wars, there is a secondary system in place to assure accurate tracking, in the event of the user killing the browser from the task manager (as mentioned in similar questions)). CANCEL would remain on the page, the issue being that no matter what button you hit, you get redirected as if you wanted to leave the page. The relevant code is below. window.onbeforeunload = confirmExit; function confirmExit() { var where_to = confirm("Click OK to exit, Click CANCEL to stay."); if (where_to == true) { window.location="logout.php"; } if (where_to == false){ alert("Returning..."); } }

  • SharedPreferences.onSharedPreferenceChangeListener not being called consistently

    - by synic
    I'm registering a preference change listener like this (in the onCreate() of my main activity): SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); prefs.registerOnSharedPreferenceChangeListener( new SharedPreferences.OnSharedPreferenceChangeListener() { public void onSharedPreferenceChanged( SharedPreferences prefs, String key) { System.out.println(key); } }); The trouble is, the listener is not always called. It works for the first few times a preference is changed, and then it is no longer called until I uninstall and reinstall the app. No amount of restarting the application seems to fix it. I found a mailing list thread reporting the same problem, but no one really answered him. What am I doing wrong?
