In the same time when first object-oriented languages were emerging, another concept inspired by general relativity and quantum mechanics was taking shape – actor model. In general terms, the Actor model was defined 1973. and was developed on a platform of multiple independent processors in a network. Similar to the object-oriented approach, this essentially mathematical model, revolved around the concept of actors. An actor is the smallest structural unit of Actor model, and just like objects, they encapsulate data and behavior. In difference to objects, however, actors communicate with each other exclusively trough messages. Messages in actors are processed in a serial manner. According to the full definition of actors, they can do three things:

• send a finite number of messages to other actors
  
• create a finite number of new actors
  
• designate the behavior to be used for the next message it receives 
  

Relational Databases Explained
How Relational Databases Work. This post talks about how indexes and transactions work on the inside of relational databases. 

Did you know that DotVVM can be used to incrementally modernize old ASP.NET Web Forms applications and lift them to .NET Core? It is much easier than doing a full rewrite, and the application can be deployed at any time during the entire process.

• Install DotVVM NuGet package in your Web Forms site
• Create a DotVVM master page using the same CSS
• Start converting ASPX pages to DotHTML syntax, one at a time
• When all the Web Forms pages are gone, change your CSPROJ to use .NET Core 

You can learn how the .NET ecosystem works on Stackify. It consists of runtimes (.NET Framework, .NET Core and Mono for Xamarin), class libraries, and a common infrastructure (runtime tools and languages).  

Big Rig exists to try and give you extended information on what your page was doing during critical RAIL actions, in particular Loading, Responding and Animating. 

Google Chrome is the most popular web browser used by web developers today. With a quick six week release cycle and a powerful set of ever expanding developer features turned the browser into a must have tool. 

Aurelia is one of the best frameworks that we have ever seen in terms of software design, hence, we decided to write a bunch of tools for its developers to pave the way for further usage.

aurelia-toolbelt is that, in which we tried to gather the best libraries in Javascript world together in aurelia fashion. Writing custom-elements, value-converters, and so on. We tried not to invent the wheel, so most of the work is a wrapper, or bridge( am not sure whether the way that we coded can be called bridge or not), around other libraries.

• Its is utterly important for us to provide a link as a reference to the libraries used, or inspired from, so that other developers can visit their product and decide on their own to use which, besides it's one way that we can respect the time and effort of those programmers.

• All libraries used in aurelia-toolbelt are open-source and free of charge; most of which are  MIT , however we will provide definition whenever it differs.

e are very pleased to announce the availability of ASP.NET Core RC2.  This release succeeds the ASP.NET 5 RC1 release and features a number of updates to enhance compatibility with other .NET frameworks and an improved runtime.
