In this blog, we will explore how to use SignalR in .NET Core to implement real-time...

“Get more done by doing this!” “Do this and be more productive!” These are common headlines in the productivity space. As a contrarian, I usually feel like I need to do the opposite when I see everyone doing something. Now, that’s not always a smart thing to do. But when it comes to career, business, and productivity, it usually pays off if you do what’s counterintuitive. So while everybody’s focused on doing more...

Back in 2008, I wrote a series of articles about using iTextSharp to generate PDF files in an ASP.NET application. I still use iTextSharp in a large MVC 5 application that I'm in the process of migrating to ASP.NET Core. The version I use is very old (4.1.6), and the API is very low level so it takes quite a while to write the code required to generate even a...

Both Kibana and Grafana are data visualization tools providing users capabilities to explore, analyze and visualize data with dashboards. The difference between Kibana and Grafana lies in their genesis. Kibana was built on top of the Elasticsearch stack, famous for log analysis and management. In comparison, Grafana was created mainly for metrics monitoring supporting visualization for time-series databases. In this article, let’s learn more about these two tools, and understand their...

The file upload feature requires essential validations to clean and maintain user data. Improper execution of a file upload input increases security vulnerability. So we must approve the uploaded files before sparing them on the server to reduce the vulnerability. Uploading files from clients to servers is among the essential features of any PHP application. However, implementing features with proper security and hassle-free configuration could be tricky. That said, developers may...

Good UX design happens when you don’t notice it during or after the experience. The main goal of good UX design is to take the user on a specific mission as quickly as possible, with the least effort possible. In good UX design, very rarely do users notice the mastery they encounter, even in the most simple and most obvious interactions like, for example, deleting items. “A user interface is like...

A Quick Guide to Transient, Scoped, and Singleton in C#. In C#, the Transient, Scoped, and Singleton scopes are options for controlling the lifetime of objects which are created by dependency injection. Transient Transient objects are created each time they are requested. This means that if a Transient is injected into multiple consumers, each consumer will receive a separate instance of the object. Scoped Scoped objects are created once per request. This means that if...
