The story of probably the most low-level bug I’ve ever had the chance to root-cause. Most of the time debugging isn’t really much to write about, especially in C# land. In a language executing on a VM, with a managed memory model, most bugs are relatively shallow and easy to fix, except for the occasional race if you’re doing multi-threading - so when suddenly...

Smart Enum Gdyby enumy miały metody Typy wyliczeniowe w C# są przydatne i przeważnie z jeden czy dwa przewijają się w każdym projekcie. Niestety prawie zawsze idą w parze z instrukcją switch, a to z kolei może wiązać się z łamaniem zasady otwarte-zamknięte z SOLID. Pomocny może być tu samoopisujący się enum, ale do tego musielibyśmy mieć możliwość definiowania w nim metod. Jest to możliwe w Javie, a w C# jeszcze nie, chyba że użyjemy biblioteki Smart Enum. Załóżmy, że istnieją u nas w k...

This video talks about the "Skip" method, and differences in implementation between dotnet frameworks. Also, we will try to implement a less flexible but faster version of the "Skip" method. Enjoy. 🙂

We are already in the second half of 2020 and a lot of books related to .NET technology have been published. I decided to collect these positions in one place for you. I will mention here some of them that get the best reviews and seem worth reading in my opinion.

This video will show you some of the performance and allocation problems that you might encounter when writing LINQ expressions and offer a couple of solutions on how to solve them. LINQ Links: ♦ https://github.com/NetFabric/LinqBenchmarks ♦ https://github.com/NetFabric/NetFabric.Hyperlinq

This video is an introduction to bit hacks; we're going to visualize bit hack expressions and learn how to construct and apply them. This video is a direct response to a previous video about bit hacks (https://youtu.be/OPFJUpdCq0I) that was too complicated to an introduction, so this video is here to fill this need. I also have an article about the same topic that goes into more detail about the examples presented here, plus it contains a more bit hacks. https://leveluppp.ghost.io/bit-hacks-in-c/ Enj...

This is a lecture about data and instruction level dependencies in high level languages like C#, Java etc. There's a lot of knowledge on the internet about this very topic but this is mostly reserved for ASM, C/C++ and hidden in CPU manuals.This is my attempt to introduce this subject to a broader audience.
