Log4j2 is the updated version of the popular and influential log4j library, used extensively throughout the Java ecosystem for so many years. Version 2.x keeps all the logging features of its predecessor and builds on that foundation with some significant improvements, especially in the area of performance. And of course, given how instrumental logging is for any application, both for audit and debugging purposes, choosing a solid logging library is quite an important decision.

When PHP version 5 was released, it incorporated a built-in model to catch errors and exceptions. Handling errors in PHP with try catch blocks is almost the same as handling errors in other programming languages. When a PHP exception is thrown, the PHP runtime looks for a catch statement that can handle that type of exception. It will continue checking the calling methods up the stack trace until a catch statement is found.

Exceptions are a commonly used feature in the Ruby programming language. The Ruby standard library defines about 30 different subclasses of exceptions, some of which have their own subclasses. The exception mechanism in Ruby is very powerful but often misused. This article will discuss the use of exceptions and show some examples of how to deal with them.

Currently, Python is the most used programming language for different projects around the world. According to statistics, 44.1% of programmers choose Python coding language for application/web development. However, that does not mean that Python developers are exempt from creating messy and inefficient code that can cost you and your clients time and money This is where Python code optimization comes in.

Microservices are increasingly used in the development world as developers work to create larger, more complex applications that are better developed and managed as a combination of smaller services that work cohesively together for more extensive, application-wide functionality. Tools such as Service Fabric are rising to meet the need to think about and build apps using a piece-by-piece methodology that is, frankly, less mind-boggling than considering the whole of the application at once.

Text manipulation is one of the most common tasks in programming with virtually all major programming languages usually supporting regex (regular expression) via their standard libraries. C# is no exception, so today we bring you a C# regex guide. You’ll learn what regexes are, why you’d want to use them and how to get started in a comprehensive, approachable manner. That way, you can start using regular expressions to solve real problems ASAP.

“Object Reference Not Set to an instance of an object.” Cast the first stone for those who never struggled with this error message as a beginner C# / .NET programmer. This infamous and dreaded error message happens when you get a NullReferenceException. This exception throws when you attempt to access a member. For instance, a method or a property on a variable that currently holds a null reference. But what does null reference exactly mean? What exactly are references?

Discover where IIS log files are located on both Windows servers and Azure. This guide offers a step-by-step tutorial on how to locate and view your IIS logs, ensuring efficient troubleshooting and security audits. For a standard Windows Server, the default log location is: %SystemDrive%\inetpub\logs\LogFiles If your IIS logs are not stored in the default location, follow these directions below to look up where they are currently being stored.

I think most C# developers would agree that LINQ is an integral part of the experience of writing code with the language. LINQ provides a fluent, intuitive, and consistent way to query data sets. In this post, we’ll help in your LINQ-mastering quest by covering the LINQ join operator. We’ll start the post with a definition of LINQ itself, so we’re all on the same page. After that, you’ll see an explanation of join operations in LINQ.

Building responsive and efficient applications in our rapidly-evolving digital world is more crucial now than ever. As software developers, we constantly look for ways to boost performance and improve the user experience. One such method is employing multithreading, a widely used yet often misunderstood feature. This comprehensive guide will dive deep into C# threading and multithreading. We’ll unpack what they are, their differences, and when and how to use each.
