  1. Operation Not Legal in the Current State - Debugging ASP.NET Core Web Applications

    The other evening I was playing around with an ASP.NET Core application. When I started debugging it, I immediately saw an error message pop up that said It was a bit of a head scratcher, so I decided to restart the debug session and see if the problem resolved itself. This didn't help and I saw the same error again.I also saw that my Chrome browser had started up, but it wasn't showing my web page. It was stuck on a notification page telling me that JavaScript debugging is now enabled in Visual...
  2. Image File Execution Options: Good, Evil, Fun.

    A #tbt from like 11 years ago...I like the Image File Execution Options section of the registry. Many developers I've encountered aren't familiar with it, though. It's under-used, and that's a shame. (For some background on IFEO, check out http://blogs.msdn.com/junfeng/archive/2004/04/28/121871.aspx and http://blogs.msdn.com/greggm/archive/2005/02/21/377663.aspx.) So far, I've been able to use it for many things, including perhaps some things that it wasn't intended for. The most common value to...
  3. How to debug Django web apps using chrome developer tools and Django Debug Panel

    Django is a great framework for developing fast web applications with python, and it can certainly save you a ton of time if you are using python.  It's one of my favorite frameworks that is around right now, and I think they do best at describing why right on their website. "Django, the web framework for perfectionists with deadlines"It's the framework that I choose if I need something up and running, yesterday, but I still want it to be something I would not be embarrassed that I'm the...
  4. Configure RoundCube on Debian 8 (Jessie) - Perfect Server Debian 8 (Apache, BIND, Dovecot, ISPConfig 3)

    Debian 8 (Jessie) doesn't contain RoundCube in it's repositories. Why, I don't know :) . In ISPConfig3, Perfect Server, Debian 8, you get SquirrelMail, but I don't like how it looks. With some trouble setting it up, I managed to configure RoundCube on Debian 8 and make it wokring with ISPConfig3. Used many sources to make it work and decided to create this manual that you’re reading.I presume that you have configured your server with Perfect Server Debian 8 (Apache, BIND, Dovecot, ISPConfig 3) configuraton...

  7. Http Patterns: Progress

    A progress resource is usually a temporary resource that is created automatically by the server to provide status on some long running process that has been initiated by a client. It is used to provide feedback to an end user and point to the results of an operation once it has completed.HTTP is a client/server request and response protocol. It does not provide for server initiated communications. If a client makes a request to a server that is likely to take a long time, e.g. 5 seconds or longer,...
  8. HTTP Patterns : Factory

    A factory resource is one that is used to create other resources.Sometimes it is difficult to create a complete resource representation on the client without some involvement from the server. It may be that the server is responsible for creating a unique identifier for the new resource, so a PUT request is not possible. Or other attributes of the resource may be dependent on existing server state. For example, creating a order resource where the order quantity may be adjusted based on in-stock quantity.
  9. HTTP Patterns : Bouncer

    A resource designed to accept a request body containing complex query parameters and redirect to a new location to enable the results of complex and expensive queries to be cached.There are practical limitations to the length of a URL on the Web. In order to send complex queries it is sometimes necessary to use a POST method and use the request body to describe the query parameters. However, a POST method cannot return a cached response. If the complex queries take a non-trivial amount of time...
  10. HTTP Patterns : Discovery

    This type of resource is used to provide a client with the information it needs to be able to access other resources. This removes the need for a client to hardcode resource URLs which include information such as the protocol scheme, host, path and query string.The primary problem addressed by a discovery resource is allowing API developers to change various elements of their API without having to notify client developers of the change and potentially force those customers to redeploy their application.
