  • Remote Desktop AND monitor fail on restart (Win2008R2)

    - by Wesley
    I am in the process of building a small 3 server farm. Each machine is running Window Server 2008 R2. As is normal, I am in the process of installing patch after patch to bring the machine up to snuff. Every time I restart the machine, or most every time, when I try to remote in to the machine I get the Log In window, but then almost immediately I get the message that my remote session was ended. If I physically walk over to the machine and plug in a monitor and keyboard, I see nothing. If I leave the keyboard and monitor in and restart the machine by force, the computer reboots just fine. When windows starts, I get no error message about windows not starting or being shut off unexpectedly. Once I log into the machine physically by the keyboard, I can then remote in to the machine at that point. Very confused. This happens on all 3 machines, these machines have different hardware.

  • Virtual PC in Remote Desktop session runs very slowly??

    - by Michael Bray
    I have a VPN to my work which is quite fast... I Remote Desktop to my work PC, which is running a Microsoft Virtual PC. Working with the PC while I'm actually at work isn't too bad, but when I try to interact with it over the remote desktop, it is VERY slow to respond. Even simple typing can be slow, but screen painting and response time is painfully obvious. Any suggestions to help speed it up?

  • How would I broadcast a subdomain/virtual name on a local server with people connected to the same network

    - by Sarmen B.
    I have a server connected to the router which has ubuntu 12.04. It is has apache/mysql/php all installed ready to go. the folder structure is like this: /var/www -- this isnt the root -/libs -/logs -/public - this is the root -/vhosts - all subdomains go here I have a folder in vhosts named mysite. I went into /etc/apache2/sites-available and created a file and here are the contents - (vhost file). and I also added an entry in /etc/hosts file containing: 127.0.1.1 mysite.dev and I also did sudo a2ensite mysite i tried accessing the site from a computer via mysite.dev and our public ip into the server but i was not able to view it. the public directory in the structure above does display on all computers when i try our public ip. but for anything added in vhosts the site wont show. there is no domain attached its just our ip. I tried changing the port from 80 to say 9999 in the mysite file in sites-available and tried myip:9999 but that didnt work either. what am I doing wrong? edit: i forgot to mention that the server is dmzed on the router.

  • How to use routing in a ASP MVC website to localize in two languages - But keeping exiting URLs

    - by Anders Pedersen
    We have a couple ASP MVC websites just using the standard VS templates default settings - Working as wanted. But now I want to localize these website ( They are now in Dutch and I will add the English language ) I would like to use routing and not Resource because: 1. Languages will differ in content, numbers of pages, etc. 2. The content is mostly text. I would like the URLs to look some thing like this - www.domain.com/en/Home/Index, www.domain.nl/nl/Home/Index. But the last one should also work with - www.domain.nl/Home/Index - Witch is the exciting URLs. I have implemented Phil Haacks areas ViewEngine from this blogpost - http://haacked.com/archive/2008/11/04/areas-in-aspnetmvc.aspx. But only putting the English website in the areas and keeping the Dutch in old structure. Witch are served as Phils default fallback. But the problem is here that I have to duplicate my controllers for both language's. So I tried the work method described in this tread - http://stackoverflow.com/questions/1712167/asp-net-mvc-localization-route. It works OK with the ?en? and /nl/ but not with the old URLs. When using this code in the global.asax the URL without the culture isn't working. public static void RegisterRoutes(RouteCollection routes) { //routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{culture}/{controller}/{action}/{id}", // URL with parameters new { culture = "nl-NL", controller = "Home", action = "Index", id = "" } // Parameter defaults ); routes.MapRoute( "DefaultWitoutCulture", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I properly overlooking some thing simple but I can't get this to work for me. Or are there a better way of doing this?

  • Why does Saxon evaluate the result-document URI to be the same?

    - by Jan
    My XSL source document looks like this <Topology> <Environment> <Id>test</Id> <Machines> <Machine> <Id>machine1</Id> <modules> <module>m1</module> <module>m2</module> </modules> </Machine> </Machines> </Environment> <Environment> <Id>production</Id> <Machines> <Machine> <Id>machine1</Id> <modules> <module>m1</module> <module>m2</module> </modules> </Machine> <Machine> <Id>machine2</Id> <modules> <module>m3</module> <module>m4</module> </modules> </Machine> </Machines> </Environment> </Topology> I want to create one result-document per machine, so I use the following stylesheet giving modelDir as path for the result-documents as parameter. <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" name="myXML" doctype-system="http://java.sun.com/dtd/properties.dtd"/> <xsl:template match="/"> <xsl:for-each-group select="/Topology/Environment/Machines/Machine" group-by="Id"> <xsl:variable name="machine" select="Id"/> <xsl:variable name="filename" select="concat($modelDir,$machine,'.xml')" /> <xsl:message terminate="no">Writing machine description to <xsl:value-of select="$filename"/></xsl:message> <xsl:result-document href="$filename" format="myXML"> <xsl:variable name="currentMachine" select="Id"/> <xsl:for-each select="current-group()/LogicalHosts/LogicalHost"> <xsl:variable name="environment" select="normalize-space(../../../../Id)"/> <xsl:message terminate="no">Module <xsl:value-of select="."/> for <xsl:value-of select="$environment"/></xsl:message> </xsl:for-each> </xsl:result-document> </xsl:for-each-group> </xsl:template> As my messages show me this seems to work fine - if saxon would not evaluate the URI of the result-document to be the same and thus give the following output. Writing machine description to target/build/model/m1.xml Module m1 for test Module m2 for test Module m1 for production Module m2 for production Writing machine description to target/build/model/m2.xml Error at xsl:result-document on line 29 of file:/C:/Projekte/.../machine.xsl: XTDE1490: Cannot write more than one result document to the same URI, or write to a URI that has been read: file:/C:/Projekte/.../$filename file:/C:/Projekte/.../machine.xsl(29,-1) : here Cannot write more than one result document to the same URI, or write to a URI that has been read: file:/C:/Projekte/.../$filename ; SystemID: file:/C:/Projekte/.../machine.xsl; Line#: 29; Column#: -1 net.sf.saxon.trans.DynamicError: Cannot write more than one result document to the same URI, or write to a URI that has been read: file:/C:/Projekte/.../$filename at net.sf.saxon.instruct.ResultDocument.processLeavingTail(ResultDocument.java:300) at net.sf.saxon.instruct.Block.processLeavingTail(Block.java:365) at net.sf.saxon.instruct.Instruction.process(Instruction.java:91) Any ideas on how to solve this?

  • Can knowing C actually hurt the code you write in higher level languages?

    - by Jurily
    The question seems settled, beaten to death even. Smart people have said smart things on the subject. To be a really good programmer, you need to know C. Or do you? I was enlightened twice this week. The first one made me realize that my assumptions don't go further than my knowledge behind them, and given the complexity of software running on my machine, that's almost non-existent. But what really drove it home was this Slashdot comment: The end result is that I notice the many naive ways in which traditional C "bare metal" programmers assume that higher level languages are implemented. They make bad "optimization" decisions in projects they influence, because they have no idea how a compiler works or how different a good runtime system may be from the naive macro-assembler model they understand. Then it hit me: C is just one more abstraction, like all others. Even the CPU itself is only an abstraction! I've just never seen it break, because I don't have the tools to measure it. I'm confused. Has my mind been mutilated beyond recovery, like Dijkstra said about BASIC? Am I living in a constant state of premature optimization? Is there hope for me, now that I realized I know nothing about anything? Is there anything to know, even? And why is it so fascinating, that everything I've written in the last five years might have been fundamentally wrong? To sum it up: is there any value in knowing more than the API docs tell me? EDIT: Made CW. Of course this also means now you must post examples of the interpreter/runtime optimizing better than we do :)

  • Is it true that in most Object Oriented Programming Languages, an "i" in an instance method always r

    - by Jian Lin
    In the following code: <script type="text/javascript"> var i = 10; function Circle(radius) { this.r = radius; this.i = radius; } Circle.i = 123; Circle.prototype.area = function() { alert(i); } var c = new Circle(1); var a = c.area(); </script> What is being alerted? The answer is at the end of this question. I found that the i in the alert call either refers to any local (if any), or the global variable. There is no way that it can be the instance variable or the class variable even when there is no local and no global defined. To refer to the instance variable i, we need this.i, and to the class variable i, we need Circle.i. Is this actually true for almost all Object oriented programming languages? Any exception? Are there cases that when there is no local and no global, it will look up the instance variable and then the class variable scope? (or in this case, are those called scope?) the answer is: 10 is being alerted.

  • Does using functional languages help against computing values repeatedly?

    - by sharptooth
    Consider a function f(x,y): f(x,0) = x*x; f(0,y) = y*(y + 1); f(x,y) = f(x,y-1) + f(x-1,y); If one tries to implement that recursively in some language like C++ he will encounter a problem. Suppose the function is first called with x = x0 and y = y0. Then for any pair (x,y) where 0 <= x < x0 and 0 <= y < y0 the intermediate values will be computed multiple times - recursive calls will form a huge tree in which multiple leaves will in fact contain the same pairs (x,y). For pairs (x,y) where x and y are both close to 0 values will be computed numerous times. For instance, I tested a similar function implemented in C++ - for x=20 and y=20 its computation takes about 4 hours (yes, four Earth hours!). Obviously the implementation can be rewritten in such way that repeated computation doesn't occur - either iteratively or with a cache table. The question is: will functional languages perform any better and avoid repeated computations when implementing a function like above recursively?

  • When creating a WCF Service with NetTcpBinding, use endpoint "localhost" or machine's host name?

    - by Elan
    I have a WCF service that uses the NetTcpBinding and is running within a Windows service. Remote clients connect to this service. So far, I have defined the endpoint to use "localhost". If the host machine has multiple network adapters, will it receive messages on all adapters? Would it be better to assign the machine's host name to the endpoint instead of "localhost"? What are the advantages/disadvantages?

  • Is there any analog of TCPvcon which allows to close TCP connection on remote machine?

    - by Miollnyr
    Hi, I started to use SysInternals suite, and it is great. But I wonder, whether there is any analog of TCPvcon, which allows to logon to remote machine, like psexec does, and then get list of TCP connections from there (similar to pslist functionality), and then to close some of connections (similar to pskill functionality). I am speaking about windows console tools and I would like to avoid installing something on remote machine is this is possible.

  • can I run C# built-in unit test in build machine?

    - by 5YrsLaterDBA
    can I run C# built-in unit test in build machine which doesn't have Visual Studio installed? We are thinking add unit test to our Visual Studio 2008 C# project. Our build machine doesn't have VS installed and we want to integrate the new unit test with our auto-build system. Is MSTest the executable to launch the Team Test unit test?

  • Under what circumstances does it make sense to run a WCF client and server on the same machine?

    - by Rising Star
    In Learning WCF, by Michele Bustamante, there is a section that describes a binding called the NetNamedPipes binding. The books says that this binding can only be used for WCF services that will be called exclusively from the same machine. Under what circumstances would it make sense to use this? Ordinarily, I would write asynchronous code without using WCF... Why would Microsoft provide something for WCF that can only run on the same machine?

  • After using modern languages, can C NOT be painful?

    - by Alexandre
    I started my computer engineering course recently and we've been using C for a couple of things. Before starting university, I was doing a lot of web development. I've written a lot of PHP code (yuck!) and for the last year or so Ruby exclusively. aside: I love Ruby, love it! So after a year of heavy Ruby development, is it wrong to think that C should be avoided at all costs unless absolutely necessary? Right now it seems to me I should try to a) get it to run in Ruby b) if it's too slow, try Java c) if it's too slow, use C Is there anyone who jumps straight to C if a VM (Ruby, Java, Python, etc) can be used on the machine and speed is not an issue? In other words, can C NOT be painful?
