If you write copious amounts of CSS, a pre-processor can greatly decrease your stress levels and save you a lot of precious time. Using tools such as Sass, Less, Stylus or PostCSS makes large and complicated stylesheets clearer to understand and easier to maintain. Thanks to features like variables, functions and mixins the code becomes more organized, allowing developers to work quicker and make less mistakes. 

Build Real App in Angular 10 and ASP.Net Web API

These are 2 of the hottest frameworks right now for the ‘back-end’ (Microsoft’s ASP.NET Core) and the ‘front-end’ (Google’s Angular) and are well worth spending the time to learn.
This course starts from scratch, you neither need to know Angular 1 nor Angular 2
We will start from nothing and incrementally build this property dealing application front-end using Angular 10.
And then we will connect our front-end with the Web-API until we have a fully functional Web Application that we will publish to Firebase and then on IIS.

ClosedXML is a .NET library for reading, manipulating and writing Excel 2007+ (.xlsx, .xlsm) files. It aims to provide an intuitive and user-friendly interface to dealing with the underlying OpenXML API.  

Running a Node.js App (Angular/React) on Android using Termux  

Microbenchmark testing Python, Numba, Mojo, Dart, C/gcc, Rust, Go, JavaScript, C#, Java, Kotlin, Pascal, Ruby, Haskell performance in Mandelbrot set generation 

Benchmarking several languages/tools with Mandelbrot set generation. 1-to-1 translation of code from one language to another. No SIMD, no multithreading (except prange() trick with Numba), no tricks (e.g. skipping sqrt), a bare minimum of language specific adjustments to make the code nicer while keeping all loops and operations in place.

Day 1 - Installing and Running .NET Core on a Windows Box
Day 2 - Taking a Look at the Visual Studio Templates for .NET Core
Day 3 - Running a .NET Core app on a Mac
Day 4 - Creating a NuGet Package from .NET Core app

Day 7 - Creating an ASP.NET Core Web Application 

A .NET guideline specifies that an application should never throw a NullReferenceException. However, many applications and libraries do. The NullReferenceException is the most common exception happening. That’s why C# 8 tries to get rid of it. With C# 8, reference types are not null be default. This is a big change, and a great feature. However, what about all the legacy code? Can old libraries be used with C# 8 applications, and can C# 7 applications make use of C# 8 libraries?

This article demonstrates how C# 8 allows mixing old and new assemblies.
