Difference between \n and \r 👀

In Unix and all Unix-like systems, \n is the code for end-of-line, \r means nothing special. 🤷🏻‍♂️

As a consequence, in C and most languages that somehow copy it (even remotely), \n is the standard escape sequence for end of line (translated to/from OS-specific sequences as needed)

in old Mac systems (pre-OS X), \r was the code for end-of-line instead. 🖥

As a (surprising) consequence (harking back to OSs much older than Windows), \r\n is the standard line-termination for text formats on the Internet. 🌏

For electromechanical teletype-like "terminals", \r commands the carriage to go back leftwards until it hits the leftmost stop (a slow operation), \n commands the roller to roll up one line (a much faster operation) — that's the reason you always have \r before \n, so that the roller can move while the carriage is still going leftwards!.

For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller) 😉

DRY - Dont Repeat Yourself 🙅🏻‍♂️

Duplication can lead to maintenance nightmares, poor factoring, and logical contradictions. ❌

The DRY Principle states :

"Every piece of knowledge must have a single, unambiguous, authoritative representation within a system."

🔹🔸🔹🔸

Duplication, and the strong possibility of eventual contradiction, can arise anywhere in :

• Architecture
• Requirements
• Code
• Documentation

The effects can range from mis-implemented code and developer confusion to complete system failure.

🔺🔹🔺🔹

Advantages of DRY 💎 :

• Maintainability
• Readability
• Reuse
• Testing

Do You Know Where Your TempData is ❓

TempData is a bucket where you can dump data that is only needed for the following request. 📦

That is, anything you put into TempData is discarded after the next request completes. ❎

This is useful for one-time messages, such as form validation errors❗️

If you need something more persistent, Session is likely what you’re looking for. 📥

By default, TempData is stored in the session.

🔹🔸🔹🔸

In this article you see how TempData works and how you can use another provider instead of Session to store the data. 🌀

MVC TempData – Peek vs Keep 🤙🏻

Most of the MVC developer knows that TempData is used to preserve data for a single request but reality is that TempData can pass data for next request also. 🤷🏻‍♂️

In this article we will discuss how to persist data with TempData using Keep and Peek method.

As well we will also see the difference between Keep and Peek method. 🤔

What is Unit Testing & Why You Need to Lean It ⁉️

Unit testing is the practice of writing code to test your code and then run those tests in an automated fashion. ✅

🔹🔸🔹🔸

Here is an example. 👨🏻‍💻

Imagine you have this function somewhere in your code.
It’s a basic calculate function that takes an input and depending on some conditions, it returns different values.

public float CalculateTax(int input) 
{
    if (x) return ...;
    if (y) return ...;
    return ...;
}

If you want to test this function manually :

1️⃣ You have to run your application
2️⃣ Perhaps you have to login
3️⃣ Maybe do a few clicks here
4️⃣ There to get to a page where this function is used.
5️⃣ You have to fill out a form
6️⃣ Submit it
7️⃣ Verify if this function returned the right result.

And then you have to repeat all these steps, each time using different values in your form. 🤦🏻‍♂️

🔸🔹🔸🔹

Manual testing is expensive 💸

As you can see, this is very time-consuming. ⌛️

This workflow to test this function may take several minutes every time❗️

Now to make matters worse, this is not the only function in your application. 🌍

In a real application, you have tens or hundreds of functions like this ❗️

As your application grows in size and complexity, the time required to manually test all the different bits and pieces increases exponentially. ⏱

So, that’s why we use Automated Testing. ♻️

Why you should join .NET Core and ASP.NET Core train ❓🚀

• .NET Core is a cross-platform version of .NET, that supports almost all that .NET supported. 🖥

🔸🔹🔸

• .NET Core and ASP.NET Core are FREE and Open Source but also they are supported by Microsoft. 💸

🔹🔸🔹

• ASP.NET Core is cross-platform web framework built on top of .NET Core.

It is built from scratch, however, a lot of old concepts and patterns are still the same. ✅

🔸🔹🔸

• Both, ASP.NET Core and .NET Core are faster and easier to work with, than their predecessors. 💨

🔹🔸🔹

• Node. is fast – over 400 000 requests per second.

• ASP.NET Core is blazing fast❗️– ASP.NET Core (on Linux ! ) itself can handle over 2 Million requests per second.

• ASP.NET Core MVC can handle over 1 million requests per second ❕
