Where will I start, what should I do, where will I get material, what so ever be the case there is always a “where” or “what” question. Knowing exactly which path to take as a newbie in technology is almost impossible unless you follow a strict guide from a mentor or any other source. This article is more like a guide through the walk of a self-taught web developer.

Explicit Interface Implementation is a complex and rarely used technique that allows a single class to inherit from multiple interfaces that have the same method signature. Explicitly implementing each interface, prepending the interface name to the method, allows the same method signature to exist in the same class. I shall not demonstrate that here, but there are plenty of examples of this online. There is another benefit to explicitly implementing an interface, and that is to hide members from being accessed via the class reference. I’ll create an example of this technique using a factory design pattern and Fruit class and a console application that you can step through via F11. If you create a new C# console application in Visual Studio, then copy and paste all of the below code, you can step through (F11) the code to see how it works.

Web security is a topic that is often overlooked by frontend developers. When we assess the quality of the website, we often look at metrics like performance, SEO-friendliness, and accessibility, while the website’s capacity to withstand malicious attacks often falls under the radar. And even though the sensitive user data is stored server-side and significant measures must be taken by backend developers to protect the servers, in the end, the responsibility for securing that data is shared between both backend and frontend. While sensitive data may be safely locked in a backend warehouse, the frontend holds the keys to its front door, and stealing them is often the easiest way to gain access.

590. Variadic Template in C++: Implementing Unsophisticated Tuple

From C++11, std::tuple is an incredible expansion to Modern C++, that offers a fixed-size col­lec­tion of het­ero­ge­neous values. Un­for­tu­nately, tu­ples can be somewhat dubious to manage in a conventional fash­ion. But, subsequently released C++ stan­dard in­tro­duced a few fea­tures & helpers that greatly re­duce the nec­es­sary boil­er­plate. So, in this article, I will explain the variadic template in C++ with the help of unsophisticated tuple implementation. And also walks you through a tricky part of tuple i.e. loop through tuple element. In spite of the fact that I have shrouded the variadic template in my prior article i.e. C++ Template: A Quick UpToDate Look. So, my focus here would be a blend of variadic template & tuple implementation with more up to date C++ gauges.
