Roadmap - How to become Linux Kernel Developer - Device Drivers Programmer and a Systems Software Expert ↗
Wednesday' 15-Jul-2020
Many viewers and even sometimes my students ask me how I can become a kernel programmer or just device driver developer and so on. So I shot this video (and an add-on video) where I summarized steps and a roadmap to become a full-fledged Linux Kernel Developer.

Linux Kernel Module to Drop Packets captured via netfilter hooks ↗
Wednesday' 15-Jul-2020
Here is my sample Kernel Module to drop packets (i.e sk_buff instance) captured via netfilter hooks. When you want to drop packets in your custom netfilter hooks make sure you never do a manual kfree_skb(skb) API call. Since it is anyway performed once the flow of the code moves out of your kernel module netfilter hook. All you need to do is to return NF_DROP to drop gracefully the desired packet. Here is my detailed video and a sample Linux Kernel module.

Arduino UNO - RO Water Purifier Controller ↗
Wednesday' 15-Jul-2020
Here is a Youtube VLOG of my DIY RO Water Purifier Controller done via Arduino UNO. I want the Arduino UNO to control the RO pump, so that it pumps for a specific duration and stops automatically. This is done via Opto-isolated 4 Channel 5V 10A Relay Board meant for Arduino UNO, Raspberry Pi or similar SoC boards which offers GPIO pins. To this relay I have connected the RO water purifier booster pump which works at 24V DC connected via 220V AC to 24V DC power supply adaptar. I have also connected a small active 5V buzzer to notify the progress and completion as it fills the tank/canister.

Compiling a C Compiler with a C Compilter | Compile gcc with gcc ↗
Wednesday' 15-Jul-2020
The fundamental aspect of a programming language compiler is to translate code written from language to other. But most commonly compilers will compile code written in high-level human friendly language such as C, C++, Java, etc. to native CPU architecture specific (machine understandable) binary code which is nothing but sequence of CPU instructions. Hence if we see that way we should able to compile gcc Compiler source code with a gcc Compiler binary.
