SonarLint is a free IDE extension that lets you fix coding issues before they exist! Like a spell checker, SonarLint highlights Bugs and Security Vulnerabilities as you write code, with clear remediation guidance so you can fix them before the code is even committed. SonarLint in VS Code supports analysis of C, C++, HTML, Java, JavaScript, PHP, Python and TypeScript, and you can install it directly from the VS Code Marketplace!
.NET MAUI for Beginners
8 videos
.NET Multi-platform App UI (.NET MAUI) is a framework for building modern, multi-platform, natively compiled iOS, Android, macOS, and Windows apps using C# and XAML in a single codebase. In this video series you will learn how to get started with .NET MAUI, C#, and Visual Studio to build your very first cross-platform desktop and mobile app.
interface I {
string M1() => "I.M1";
string M2() => "I.M2";
}
abstract class A : I {}
class C : A {
public string M1() => "C.M1";
public virtual string M2() => "C.M2";
}
class Program {
static void Main() {
I obj = new C();
System.Console.WriteLine(obj.M1());
System.Console.WriteLine(obj.M2());
}
} 
It comes with full support for .NET Core 2.0, adds MSTest, various NuGet improvements, a new debugger tool window for visualizing Parallel Stacks and marking of instances, new refactorings and more. And with ReSharper 2017.2 now released, we’ve updated the ReSharper version powering Rider, too. Which brings improved support for C# 7.0, initial support for C# 7.1, new code inspections, navigation improvements, and so on. Let’s look at a few highlights!
UI-Router ابزاری برای مسیریابی در AngularJS است که این امکان را برایتان فراهم می‌کند تا بخش‌های برنامه رابط کاربریتان را به شکل یک ماشین حالت ساماندهی کنید. برخلاف سرویس route$ که بر اساس مسیریابی URLها ساماندهی شده و کار می‌کند، UI-Router بر اساس حالت‌ها کار می‌کند، که این حالت‌ها می‌توانند در صورت لزوم مسیریابی هم داشته باشند.

Accounting For Software Engineers
The difference between accountants and software engineers, when it comes to accounting systems, is about what we primarily care about. Accountants care about meaning: is the quick ratio in good shape? Is income growing at an expected rate? How do we deal with an upcoming expense? Software engineers care about: will we properly move money around so that the balances are correct given certain latency, concurrency, etc.? Do we have the information required to generate the Income Statement? How do we represent a credit memo?
