  • In Perl, given two IO::Socket's how do I connect 1st socket's input to 2nd's output and vice versa?

    - by bodacydo
    Suppose I have made two connections in Perl with the help of IO::Socket. The first has socket $s1 and the second has socket $s2. Any ideas how can I connect them together so that whatever gets received from $s1 got sent to $s2 and whatever gets received from $s2 got sent to $s1? I can't understand how to do it. I don't know how to connect them together. I would expect to do something like $s1->stdin = $s2->stdout and $s2->stdin = $s1->stdout, but there are no such constructs in Perl. Please help me! Thanks, Boda Cydo.

  • Creating a System.Web.UI.Page programatically in IHTTPHandler

    - by ObiWanKenobi
    I am trying to use the ASP.NET (3.5) "Routing Module" functionality to create custom pages based on the contents of the URL. Various articles, such as this one: http://blogs.msdn.com/mikeormond/archive/2008/05/14/using-asp-net-routing-independent-of-mvc.aspx explain how to use ASP.NET Routing to branch to existing pages on the web server. What I would like to do is create the page on-the-fly using code. My first attempt looks like this: public class SimpleRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { string pageName = requestContext.RouteData.GetRequiredString("PageName"); Page myPage = new Page(); myPage.Response.Write("hello " + pageName); return myPage; } } But this throws an HTTPException saying "Response is not available in this context." at the Response.Write statement. Any ideas on how to proceed? UPDATE: In the end, I went with an approach based on IHttpModule, which turned out to be rather easy.

  • REST, caching, and authorizing with multiple user roles

    - by keithjgrant
    We have a system with multiple different levels of access--sometimes even for the same user as they switch between multiple roles. We're beginning a discussion on moving over to a RESTful implementation of things. I'm just starting to get my feet wet with the whole REST thing. So how do I go about limiting access to the correct records when they access a resource, particularly when taking caching into consideration? If user A access example.com/employees they would receive a different response than user B; user A may even receive a different response as he switches to a different role. To help facilitate caching, should the id of the role be somehow incorporated into the uri? Maybe something like example.com/employees/123 (which violates the rules of REST), or as some sort of subordinate resource like example.com/employees/role/123 (which seems silly, since role/### is going to be appended to URIs all over the place). I can help but think I'm missing something here.

  • shell script fun! performing action on each subdirectory from a given path

    - by pocketfullofcheese
    I am writing a shell script (which I suck at) and I need some help. Its a script that is moving things from git to CVS (not important). The thing is, i a file path: controllers/listbuilder/setup/SubmissionRolesListbuilderHandler.inc.php and I need to be able to do: cvs add controllers; cvs add controllers/listbuilder; cvs add controllers/listbuilder/setup; cvs add controllers/listbuilder/setup/SubmissionRolesListbuilderHandler.inc.php Can someone help me out? The best I've come up with so far is to recursively add ALL files in my working tree, but that seems overly inefficient.

  • What Would You Do With 48 Cores?

    - by jeroen.vangoey
    The AMD Server team has announced a contest where they are seeking the best essays, videos, or blog posts documenting how you might use 48 cores. They are primarily looking for "what you can do to help society, to help others. That will give you an edge." So, what would you do with 48 cores? Disclaimer: I am not affiliated with AMD (I am even not eligible for the contest because I don't live in the US/Canada) but would love to see what the SO community can come up with.

  • ASP.net MVC - Check status request

    - by vdhant
    Hi guys Just wondering if its possible to get the status of a request from another request? To help provide some context, I want to use ajax to upload some files to the server. When the upload is started I want triggered another ajax request that checks to see how much of the file has been uploaded (or in other words how big was the other request and how far through receiving the request is the server). I was thinking that I could use a guid or something similar to ensure that I am checking the status of the right request. But how do I check the status of another request??? Cheers Anthony

  • Powershell 2.0 error handling - Command line call vs. ISE

    - by Gromix
    Hi, In the context of deployment scripts, I would like to capture any error than happens and stop immediately. I have notice some significant differences between the following calls: powershell.exe -File Script.ps1 powershell.exe -Command "& '.\Script.ps1'" powershell.exe .\Script.ps1 For example, the -File call will handle errors in the exact same way as the ISE. The other two seem to ignore the $ErrorActionPreference variable, and do not seem to catch Write-Error in try/catch blocks. Could someone help me understand the implications of each one, and why they are behaving differently? Thanks, Romain

  • Removing stopwords,but should return as a line

    - by Sarath R Nair
    My question may appear silly. But as I am a rookie in Python , help me out. I have to pass a line to a stopword removal function. It works fine. But my problem is return of the function is appending the words. I want it as like follows: line = " I am feeling good , but I cant talk" Let "I,but,cant" are stopwords. After passing to the function , my output should be as "am feeling good , talk". What I a getting now is [['am','feeling','good','talk']]. Help me.

  • Unbelievable: Cannot cast from class X to its super class

    - by Phuong Nguyen de ManCity fan
    I'm encountering a very weird problem with Spring (3.0.1.RELEASE), TestNG (5.11) and Maven Surefire (2.5). I have a test class that extends a Spring helper class for testNG so that test context can be loaded from an xml file (that contains some bean definitions). My project was imported into eclipse using m2eclipse (using Import Maven Project) The class run fine in Eclipse TestNG runner. However, it throws this exception with Maven Surefire Caused by: java.lang.ClassCastException: com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl cannot be cast to javax.xml.parsers.DocumentBuilderFactory at javax.xml.parsers.DocumentBuilderFactory.newInstance(DocumentBuilderFactory.java:123) at org.springframework.beans.factory.xml.DefaultDocumentLoader.createDocumentBuilderFactory(DefaultDocumentLoader.java:89) at org.springframework.beans.factory.xml.DefaultDocumentLoader.loadDocument(DefaultDocumentLoader.java:70) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:388) I have eliminated all involved dependencies in my pom so that the two classes com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl and javax.xml.parsers.DocumentBuilderFactory are coming from JRE only (the rt.jar). So, it looks so unbelievable to me. I wonder if there is any mechanism in loading class that can explain for this behavior? Thanks.

  • bash: how to know NUM option in grep -A -B "on the fly" ?

    - by Michael Mao
    Hello everyone: I am trying to analyze my agent results from a collection of 20 txt files here. If you wonder about the background info, please go see my page, what I am doing here is just one step. Basically I would like to take only my agent's result out of the messy context, so I've got this command for a single file: cat run15.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' This means : after the regex match, continue forward by 50 lines, stop, then match a line separator starts with "==", go back by 50 lines, if possible (This would certainly clash the very first line). This approach depends on the fact that the hard-coded line number counter 50, would be just fine to get exactly one line separator. And this would not work if I do the following code: cat run*.txt | grep -A 50 -E '^Agent Name: agent10479475' | grep -B 50 '^==' The output would be a mess... My question is: how to make sure grep knows exactly when to stop going forward, and when to stop getting backward? Any suggestion or hint is much appreciated.

  • Good "Modelling & Simulation" book recommendations for programmers?

    - by Harry
    I'm a programmer, and have completely forgotten all the advanced engineering Math I studied ~20 years ago at school. I now have an urgent need to learn about Modelling and Simulation. Though the present context is Disease Modelling, I'm not sure if there's such a thing as 'general' modelling and simulation... with concepts / techniques / algorithms that could be used in just about any domain (and not just limited to biology, finance, trade, economic, weather, etc.) Would you have any recommendations that are easy to read by a semi-Math-literate programmer? Basically, I cannot afford to drown myself in too much Math and theory behind M & S, hence this post. Tia...

  • IIS6 Metabase Compatiblity not installing correctly for Vista IIS7

    - by Mr Snuffle
    I've been bashing my head against this one for a few days, and haven't had any luck with it. I'm unable to get my VS2010 ASP.NET project to deploy to IIS. I receive the error "Unable to create the virtual directory. To access local IIS Web sites, you must install the following IIS Components IIS 6 Metabase and IIS 6 Configuration Compatibility ASP.NET In addition, you must run Visual Studio in the context of an Administrator Account" I've most certainly installed the metabase option, but it still shows up. I'm also not sure why it's telling me to install ASP.NET. Google is being entirely unhelpful, I was wondering if anyone here has any suggestions. I'm running Vista Ultimate 64Bit

  • iframe accessing parent DOM?

    - by Yuval A
    How is it possible for a script within an <iframe> to have any notion of the page containing it? Can a script in the frame access any context outside of it? What about cross-domain? Up until now I believed an <iframe> is completely agnostic to the containing page, but I have seen an example which contradicts this belief. What exactly can and can't be done from within an <iframe> with respect to the containing page?

  • Steaming a non-PCM WAV file to a SilverLight application

    - by Satumba
    Hi, I would like to allow users to play recorded WAV files that stored on a server back to a Silverlight application as a client to play them. I saw that there is a way to play a WAV file on Silverlight (here), but when i tried to impliment it, i got an error playing the file because it is not in PCM format but encoded. The files that i'm trying to play are encoded with a special encoder, so i thought that the only way is to decode the WAV file on the server and stream it back to the client. The limitation is that the decode process should occur in real time because it is not reasonable to convert all the WAV files that exists. Is it possible to do it? Which streamer can i use? (Windows Media Service can help here?) Does somebody has any experience with such a scenario? Appreciate your help.

  • When to choose LAMP over ASP.NET?

    - by Carlo
    Hello. A friend wants to start a dating website, she wants me to help her. We still haven't discussed on what platform it'll be developed, but I'm thinking she'll suggest LAMP to save a buck (which is one reason already to chose over ASP.NET already). If the dating website does well, it'll potentially hold a large amount of data (I'm not sure if this would be another reason to consider either ASP.NET or LAMP). Anyway, I ask this from an ASP.NET developer point of view. I have very little, almost null experience with LAMP, and I don't like it very much either, so if she decides to go with PHP odds are I won't help her. So what would be some good points to bring up when deciding which platform to develop on? Please be objective, I don't want this to be argumentative or anything, try to stick to facts, not opinions alone. Thanks!

  • python xml.dom.minidom.Attr question

    - by rudy
    Getting attributes using minidom in Python, one uses the "attributes" property. e.g. node.attributes["id"].value So if I have <a id="foo"></a>, that should give me "foo". node.attributes["id"] does not return the value of the named attribute, but an xml.dom.minidom.Attr instance. But looking at the help for Attr, by doing help('xml.dom.minidom.Attr'), nowhere is this magic "value" property mentioned. I like to learn APIs by looking at the type hierarchy, instance methods etc. Where did this "value" property come from?? Why is it not listed in the Attr class' page? The only data descriptors mentioned are isId, localName and schemaType. Its also not inherited from any superclasses. Since I'm new to Python, would some of the Python gurus enlighten?
