It’s a common thing for websites to serve some kind of static content, like images, sounds, fonts or videos. When deploying a new website, the most common way to serve the aforementioned content is to include these files in the app structure and allow the web server to serve the static content. In Azure, there are additional ways to serve static content, either through Azure Blob......

Session is a simple and nice way to store info in memory and has been used in ASP.NET for a long time. Since MVC came out, there were many people out there saying that session should be abandoned and replaced by other methods while others said that there is no problem using session the way we used to. As this may confuse developers that are not highly experienced in MVC, let's see what actually happens here. Before MVC Web Forms have been the basic model for a developer who has been working on ASP.NET, for a long time. Web Forms was the result of Microsoft's efforts to create a web application based on windows standards. By default, web is stateless. If I send a request, this is supposed to be a request of its own, no matter what the history between me and the web server has been. To use a RESTful model, info should be sent using GET, POST requests, cookies etc. However, this model did not resemble windows applications. In order to avoid this, developers started using state management tools, like session...

Sometimes, the response from a request is required first in order to continue with all the other API requests currently stored in your Postman folders.

A couple of days ago Facebook released Yarn, a new package manager for Javascript, with a focus on speed and consistent package dependency management across machines. With Yarn, engineers still have access to the npm registry, so I thought it worth the try to test the claimed speed improvements between package installation using yarn and npm default installation process. For my tests I used ng-lightning, a project for......

In this post I am going to make the case why returning IQueryable from a Repository Pattern is an anti-pattern and why you should not do it. I assume that you have some experience on building applications using the Layered Architecture and are familiar with various design patterns like Unit of Work and Repository pattern. You can have a look at this post if you want to find out more about the Repository Pattern. In this post I am talking the Repository pattern and Entity Framework and explain why we still need to use the Repository Pattern even if we use EF in our persistence layer. One thing we should keep in mind is that at some point our methods in the Persistence layer should return something that can be consumed by the client classes in upper layers. Clean code architecture dictates that we should program against clean interfaces and the various layers that exist in our application should communicate with each other trough interfaces so there is separation of concerns and the one layer is decoupled from the...

A common practice to increase the performance and availability of a web application is to distribute it in multiple servers across the globe. Thus, customers will be served from the data-center that is closer to them, thus reducing response latency. In addition, when one server confronts downtime, other servers will handle the requests without the user noticing it. In this post we will explore how easy it is to setup......

sparkol videoscribe portable Not like JPEGs, GIFs, and BMP images, vector graphics are not necessarily made up of a grid of pixels. Instead, vector graphics are comprised of methods, which are defined by a start and end point, along with other points, curves, and angles along the way. A path can be a line, a square, a triangle, or a curvy shape. These paths can be used to create simple drawings or intricate diagrams. Paths are even used to define the characters of specific typefaces. Since vector-based graphics are not made up of a specific number of dots, they can be scaled to a larger size and not lose any image quality. If you blow up some raster graphic, it will look blocky, or "pixelated. " When you blow up a vector graphic, the edges of each object within the graphic stay light and clean. This makes vector graphics ideal for logos, which can be small enough to appear on a organization card, but can also be scaled to fill a billboard. Common types of vector graphics include Adobe Illustrator, Macromedia Freehand,...
