  • How do I correctly set up Application Request Routing in IIS7 to route SSL requests?

    - by Matthew Belk
    I have a 3-node web farm being managed by IIS7 and Application Request Routing. I have a folder hierarchy in my web app that needs to be secured via SSL. What is the best practice for getting ARR to correctly route these SSL requests? I have installed the same certificate on all web farm servers and the server running ARR. I have tried enabling and disabling the SSL Off-loading feature Thanks, Matthew

  • Why does Ubuntu's Nautilus display a folder called "Examples" while the console displays "examples.desktop"

    - by broiyan
    These folders occur at /home/username. How does this name discrepancy arise? (Uppercase E versus lowercase e.) It seems to be a shortcut to /usr/share/example-content. How can I delete /usr/share/example-content/Ubuntu_Free_Culture_Showcase without using the command line? One possible answer is to make a privileged Nautilus using something like these SUSE instructions (link below). Unfortunately "gnomesu nautilus" gives me a "gnomesu: no such file" message and "sudo nautilus" does not do anything when added to the properties of the Launcher. Update: "sudo nautilus" from the console let's me delete but there is a mess of error messages. http://forums.opensuse.org/english/get-technical-help-here/how-faq-forums/unreviewed-how-faq/426153-how-nautilus-super-user-mode-gnome.html

  • Passing a custom variable to the PayPal API

    - by Michael
    Gday All, I am developing a site that uses PayPal to take online payments. I need to be able to send my client an email with the link to PayPal in order to pay. In this link I need a way to set a unique value (for example bookingId) that I can use to add the receipt number to the correct booking via PayPal's payment notification feature. Does anyone know what custom value I can set in order to achieve this? Cheers, Michael

  • Remote Desktop closes with Fatal Error (Error Code: 5)

    - by Swinders
    We have one PC (Windows XP SP3) that we can not log onto using a Remote Desktop session. Logging on to the PC directly (sitting in front of it using the connected keyboard and monitor) work fine. From a second PC (tried a number of different ones but all Windows XP SP3) I run 'mstsc' and type in PC name to connect to. This shows the login box which we can enter the correct login details and click OK. Within a few second we get an error: Title: Fatal Error (Error Code:5) Error: Your Remote Desktop session is about to end. This computer might be low on virtual memory. Close your other programs, and then try connecting to the remote computer again. If the problem continues, contact your network administrator or technical support. None of the computers we are using are low on memory (2Gb+) and we let windows manage the virtual memory side of things. We do not see this with any other PC and do use Remote Desktop in meeting rooms to connect to user PCs with no problems.

  • OSX pdf-kit vs Linux poppler or pdf/x

    - by Tahnoon Pasha
    I keep reading and hearing that the reason that there is no good pdf editing software for Linux is that the libraries are not as well developed. That is why there is no equivalent for Skim or Preview in Linux. I had a look a the pdf-kit documentation and the poppler documentation and they looked very similar to my admittedly non-technical view. Could someone explain to me why the OSX libraries (eg) are so much easier to write projects like Skim in than the linux ones. I'm not sure if the same applies to OSX projects to NVAlt, but it seems to be a common theme - I'd just like to understand what is behind the thesis that OSX is easier to code these projects in, and what would be involved in changing it. (I'm not disputing the value of Okular or Evince and the like, just noting that they don't have the richness of functionality of Skim, Preview or even things like Goodreader on the Ipad).

  • Java: Checking if PC is idle

    - by Scott Straughan
    This is a rather tricky question as I have found no information online. Basically, I wish to know how to check if a computer is idle in Java. I wish a program to only work if the computer is in active use but if it is idle then to not. The only way i can think of doing this is hooking into the mouse/keyboard and having a timer. MSN Messenger has that "away" feature, I wish for something similar to this.

  • how to code referral system in wordpress ?

    - by justjoe
    I'm just asking about custom feature I'm working on. If you have experience creating similar projects, what are things that need to be considered when creating similar features? PS: this is broad general question. And not something that focuses on a particular web system. And mostly will be code in PHP and wordpress. And frankly, I tend to code this not using Wordpress built-in functions.

  • Good low-cost SSL certificate providers

    - by phenry
    We need an SSL certificate to facilitate remote access and administration by a small number of employees. I don't want to have to train a bunch of non-technical users to install a self-published cert on their home computers, so I'd prefer to purchase one from a well-trusted provider. We won't be using it for any kind of e-commerce or things like that, so it seems hard to justify paying the prices demanded by some of the big-name providers. Who are some good low-cost providers to consider? What are the important differences between the offerings that are available at different price points? (And is the certificate business really as much of a racket as it seems?)

  • Is there a Windows equivalent of Unix 'CPU steal time'?

    - by Steffen Opel
    In order to assess performance monitoring accuracy on virtualization platforms, the CPU steal time has become an increasingly relevant metric - see EC2 monitoring: the case of stolen CPU for an instructive summary in the context of Amazon EC2 and IBM's paper on CPU time accounting for a more in-depth technical explanation (including illustrations) of the concept: Steal time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor. Accordingly, it is exposed in most related Unix/Linux monitoring tools nowadays - see e.g. columns %steal or st in sar or top: st -- Steal Time The amount of CPU 'stolen' from this virtual machine by the hypervisor for other tasks (such as running another virtual machine). I've been unable to figure out how to capture the same metric on Windows though, is this possible already? (Ideally for the Windows 2008 Server R2 AMIs on EC2 and via a respective Windows Performance Counters of course.)

  • Resharper Question

    - by bmw0128
    I just started using VS2008 and Resharper. I have a line: Microsoft.Office.Server.Diagnostics.PortalLog.LogString("*** BOO Feature activating ***"); VS shows "Office" as red b/c it cannot resolve symbol "Office". Can I make Resharper just add the reference automatically, or do I need to manually surf to the reference and add it?

  • What groupware/collaboration system to choose?

    - by Ivan
    I am looking for a good (stable enough, intuitive enough, and the more technologically modern and advanced - the better) free PHP-based online groupware/collaboration system. 100% UTF-8 is a requirement. OOP-style code is an advantage. And collaborative mindmapping would be a cool feature to have. The team is of ~20 people. Any suggestions?

  • Graphical sandbox for pathfinding

    - by vrode
    If you needed a clean and consistent sandbox for pathfinding what would you use? I want to experiment with different pathfinding algorithms by sending virtual units (robots) around obstacles on a geometric plane. But I don't need a feature overkill like a game engine or Flash might have, just an animated report and native collision detector. I prefer it to be scripted in python, but if there are java or C++ alternatives I would appreciate them as well.

  • Visual Studio UML Sequence Diagram

    - by ikurtz
    I was wondering if there was a Sequence Diagram generator for C#? Im using Visual Studio 2008 Professional. If not is there a quick and simple software? Im finding Enterprise Architect and Visio a bit to cryptic for a beginner. I have found the Class Diagram feature on Visual Studio, which s very useful and am hoping for a equally useful simple program to generate Sequence Diagrams. Thanks.

    What are the consequences (positive/negative) of using the unsafe keyword in C# to use pointers? For example, what becomes of garbage collection, what are the performance gains/losses, what are the performance gains/losses compared to other languages manual memory management, what are the dangers, in which situation is it really justifiable to make use of this language feature... ?

  • How to add a skin engine to asp.net MVC system

    - by Am
    I'm implementing a solution in ASP.NET MVC that later can be applied to couple of other fields. To do so it will require to re-brand the UI even though the underlying business logic wont need to change. I'd like to write the code in such a way that will allow other developers to only develop code that will only changes the UI. This is similar to the way that themes can be written against Wordpress Blog software. Can any one suggest how to organize my project to make such feature work?

  • Linux & Windows Boot Up Times in Amazon Web Service and Windows Azure

    - by Adron
    I've been working with Windows Azure and Amazon Web Services EC2 for a good many months now (almost getting to the years range) and I've seen something over and over that seems troubling. With AWS & Linux I commonly get instance startup times with EC2 around the 1-3 minute range. With AWS & Windows OS on an EC2 instance it often takes 10-20 minutes. With Windows Azure Web or Service Role I often get anywhere from 6-30 minutes waiting for a role to startup. I assume of course this involves booting up a windows instance somewhere in the fabric. I know there has always been tons of FUD about windows vs. Linux, but I'd really like to know why it is that Windows 08 or 03 boots so much slower in the cloud than Linux. Any specific technical information regarding this would be greatly appreciated! Thanks.
