Kimχ Micro: A powerful alternative to the Raspberry Pi that supports PCIe cards
A new alternative to the Raspberry Pi has been presented. Called the Kimχ Micro, the Raspberry Pi Zero-sized micro SBC has a quad-core processor and a mPCIe slot for adding PCIe cards. Read More


Linux Lands And Then Reverts Usage Of Flexible Array Members
As a change past the Linux 5.8 merge window now that the flurry of code activity has settled down was changing the use of zero-length arrays in structs with flexible array members. Linus Torvalds did pull the change into Linux 5.8 but then decided shortly afterwards to drop the change at least for the time being. Read More

Key Differences of PoE vs PoE+ vs PoE++ Switches a STH Guide
When looking to power devices using the same cables that provide data connections, PoE, or Power over Ethernet, is what you will most likely use. The explosion of IoT and connected devices mean that PoE switches are one of the fastest-growing segments in networking. You will often find three common labels for today’s PoE switches in the market: PoE switch, PoE+ switch, and PoE++ switch. Read More

What is a Linux Kernel Module - a Big Picture ↗
Saturday' 13-Mar-2021
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

Linux Kernel Programming | with or without Kernel Modules | Device Drivers ↗
Saturday' 13-Mar-2021
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.
