Today I'm writing about linux kernel patch Philosophy. Oh yes, You are right submitting kernel patches is none less than a Philosophy.

Linux Networking Stack Receive Flow Steering (RFS) aim is to increase data-cache hitrate by steering kernel processing of packets to the CPU where the application thread consuming the packet is running. RFS relies on the same RPS mechanisms to enqueue packets onto the backlog of another CPU and to wake up that CPU.

Here is a small list of Linux (Kernel, Linux Users Group) and Open-Source Communities across the world.

Here is a my multi-episode Youtube video series of me doing a live code (Code with Kiran Series). Linux Kernel GPIO drivers of Raspberry Pi offers access/control directly via sysfs filesystem interface. But often people don't see this aspect, instead as a part of IoT, they assume these GPIO pins can be only accessed by some Python, Java or C/C++ code libraries. But in the real case those libraries are just an abstract layer written around the core Kernel GPIO driver's sysfs filesystem. So here is an attempt where we learn this aspect in systems architecture point of view. And then later try to attempt writing such user-space GPIO control code without any third-party libraries. Since the sysfs driver access is via regular files (user-space context), we can now use any language of our choice and access the same like any files. In that process we can attempt writing our own bunch of abstract APIs resembling a typical GPIO access library.
