  • Debugging HeapReAlloc failure using GetExceptionCode

    - by Becky Franklin
    Hey folks, Been messing about with this all day and haven't got anywhere so I'm hoping someone can help me - I have a HeapReAlloc method failing with the error ACCESS_VIOLATION, but I'm unsure how to implement a further check using GetExceptionCode as it uses try/catch or exception or something - can someone give me a quick example of how I can use it to narrow down this failure, please? Thanks very much, Becky

  • Is it worth purchasing Mahout in Action to get up to speed with Mahout, or are there other better sources?

    - by gab
    I'm currently a very casual user of Apache Mahout, and I'm considering purchasing the book Mahout in Action. Unfortunately, I'm having a really hard time getting an idea of how worth it this book is -- and seeing as it's a Manning Early Access Program book (and therefore only currently available as a beta-version e-book), I can't take a look myself in a bookstore. Can anyone recommend this as a good (or less good) guide to getting up to speed with Mahout, and/or other sources that can supplement the Mahout website?

  • Cache SHA1 digest result?

    - by johnathan
    I'm storing several versions of a file based on a digest of the original filename and its version, like this: $filename = sha1($original . ':' . $version); Would it be worth it to cache the digest ($filename) in memcache as a key/value pair (the key being the original + version and value the sha1 hash), or is generating the digest quick enough (for a high traffic php web app)? Thanks, Johnathan

  • PDO/Oracle vs OCI

    - by jarcoal
    The company I work for currently uses some basic functions to abstract the OCI libraries as a means for DB connectivity. We're considering switching to PHP's PDO object, but from some quick searches, it looks like the Oracle driver is a bit less mature than the other PDO drivers. I would appreciate some pro/cons for PDO/Oracle from anyone who has used it in a production environment. Thanks!

  • Android adding external libraries to project

    - by wuntee
    I have a project that I would like to add external libraries to (and have them packaged with the application) but I am not sure it is happening. I read on this link: http://developer.android.com/intl/fr/guide/appendix/faq/commontasks.html how to, but they do not show up in any of the /data/data/project directories. Does anyone know how I can confirm that the libraries were in fact added to the project for use at runtime? Thanks.

  • Is this slow WPF TextBlock performance expected?

    - by Ben Schoepke
    Hi, I am doing some benchmarking to determine if I can use WPF for a new product. However, early performance results are disappointing. I made a quick app that uses data binding to display a bunch of random text inside of a list box every 100 ms and it was eating up ~15% CPU. So I made another quick app that skipped the data binding/data template scheme and does nothing but update 10 TextBlocks that are inside of a ListBox every 100 ms (the actual product wouldn't require 100 ms updates, more like 500 ms max, but this is a stress test). I'm still seeing ~10-15% CPU usage. Why is this so high? Is it because of all the garbage strings? Here's the XAML: <Grid> <ListBox x:Name="numericsListBox"> <ListBox.Resources> <Style TargetType="TextBlock"> <Setter Property="FontSize" Value="48"/> <Setter Property="Width" Value="300"/> </Style> </ListBox.Resources> <TextBlock/> <TextBlock/> <TextBlock/> <TextBlock/> <TextBlock/> <TextBlock/> <TextBlock/> <TextBlock/> <TextBlock/> <TextBlock/> </ListBox> </Grid> Here's the code behind: public partial class Window1 : Window { private int _count = 0; public Window1() { InitializeComponent(); } private void OnLoad(object sender, RoutedEventArgs e) { var t = new DispatcherTimer(TimeSpan.FromSeconds(0.1), DispatcherPriority.Normal, UpdateNumerics, Dispatcher); t.Start(); } private void UpdateNumerics(object sender, EventArgs e) { ++_count; foreach (object textBlock in numericsListBox.Items) { var t = textBlock as TextBlock; if (t != null) t.Text = _count.ToString(); } } } Any ideas for a better way to quickly render text? My computer: XP SP3, 2.26 GHz Core 2 Duo, 4 GB RAM, Intel 4500 HD integrated graphics. And that is an order of magnitude beefier than the hardware I'd need to develop for in the real product.

  • Short circuiting statement evaluation -- is this guaranteed? [C#]

    - by larryq
    Hi everyone, Quick question here about short-circuiting statements in C#. With an if statement like this: if (MyObject.MyArray.Count == 0 || MyObject.MyArray[0].SomeValue == 0) { //.... } Is it guaranteed that evaluation will stop after the "MyArray.Count" portion, provided that portion is true? Otherwise I'll get a null exception in the second part.

  • VS2010 Load Testing - Restricting ports

    - by marks-s
    As per the trouble shooting guide for VS2010 Load Testing (http://social.msdn.microsoft.com/Forums/en/vststest/thread/df043823-ffcf-46a4-9e47-1c4b8854ca13), I'm trying to restrict the range of ports used for client-controller communication. HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\VisualStudio\10.0\EnterpriseTools\QualityTools\ListenPortRange\PortRangeStart HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\VisualStudio\10.0\EnterpriseTools\QualityTools\ListenPortRange\PortRangeEnd I've set these keys on the client as described but according to netstat the client is still listening on random ports. The controller is attempting to communicate on the same random ports as the client. Anyone experienced the same?

    Hello there, I have two Services called TemplateService, TemplateReportService (both defined in one WCF Service Library) to be exposed to the client application.

Here is my app.config in WCF Library: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.web> <compilation debug="true" /> </system.web> <system.serviceModel> <services> <service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior" name="ReportingComponentLibrary.TemplateService"> <endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateService" > <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" ></endpoint> <host> <baseAddresses> <add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateService/" /> </baseAddresses> </host> </service> <service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior" name="ReportingComponentLibrary.TemplateReportService"> <endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateReportService" > <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateReportService/" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ReportingComponentLibrary.TemplateServiceBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> So, the App.config in my Windows Service(Where I am hosting above two services) will be same as above or there are only some particular sections that I need to move. Please guide. Thank you!

  • Evaluating software estimates: sure signs of unrealistic figures?

    - by Totophil
    Whilst answering “Dealing with awful estimates” posted by Ash I shared a few tips that I learned and personally use to spot weak estimates. But I am certain there must be many more! What heuristics to use in the scenario when one needs to make a quick evaluation of software project estimate that has been compiled by a third-party (a colleague, a business partner or an external company)? What are the obvious and not so obvious signs of weak software estimates that can be spotted without much detailed knowledge of task at hand?
