A detailed Youtube video series of various programming language performance and overheads - a big picture

Learning Linux Kernel Programming is always fascinating and yet challenging. So generally you may tend to learn Kernel Module programming, since such a module can be dynamically plugged into running Linux Kernel. But this will lead to confusion, and many assume kernel source is mostly a collection of these modules. Which in reality is not. Not just that, when we say Kernel Module, its a vaguely defined term. The term Module (as we know) is nothing but a collection of APIs, bunch of variables and associated data-structures. Which may or may not be a plugable kernel module. If you ask me, I am a fan of wiring Linux Kernel Modules, which may not be necessarily a pluggable kernel module. It all boils down to the address space at which these modules function inside a monolithic Linux Kernel. Which is nothing but Linux Kernel's address space. Hence here is my detailed multi-episode Youtube video series on Linux Kernel modules, a big picture and the significance of the

When learning Linux Kernel programming, often I notice my students and viewers gets confused and they start with learning writing Linux Kernel modules. And so they develop the common misconception about Kernel Programming in general. They assume writing code in Linux Kernel means writing kernel modules. Which is absolutely not. Kernel modules are an optional choice and are part of Linux Kernel. But besides modules, Linux Kernel has lot of other mainstream code. Hence if anyone wants to be a Kernel Developer, you should be aware that sometimes you add new code via modules, sometimes without them. And if you ask me, I am not much in favor of writing Kernel modules. Instead in my code, I try to integrate and make them a part of Linux Kernel so that they all get initialized during boot time. Here is an extensive Youtube video of mine on Linux Kernel Programming, with and without Kernel Modules.

Aqui está meu código de soquete UDP de amostra escrito em C. Ao contrário de outras versões, você costuma obter on-line, esta versão é voltada para desenvolvedores de software de rede e sistemas e como uma referência rápida até mesmo para programadores de software experientes. Neste exemplo / modelo, estou enviando bytes de dados binários brutos de teste do cliente de amostra UDP para o servidor de amostra UDP registrado. O código já possui documentação na forma de comentários (como você pode ver abaixo). Você pode baixar meu código-fonte abaixo e você pode usá-lo diretamente em seus projetos ou você pode usar o mesmo para fins de aprendizagem para entender sobre a programação de soquete de espaço do usuário via protocolo de camada de transporte UDP IPv4.
