The little book about OS development (littleosbook.github.io)
This text is a practical guide to writing your own x86 operating system. It is designed to give enough help with the technical details while at the same time not reveal too much with samples and code excerpts. We’ve tried to collect parts of the vast (and often excellent) expanse of material and tutorials available, on the web and otherwise, and add our own insights into the problems we encountered and struggled with.

People Don't Read Instructions (softuts.com)
I always feel trapped when one of those product tours starts. They show me buttons and features before I even have any idea what the product is about. I personally prefer exploring freely. It's the same in computer games. This kind of "Press A to jump, go here, take out your sword" tutorials, where you are forced to take a specific action, don't do a good job of teaching the user how the interface works.

Build your own SQLite, Part 4: reading tables metadata (sylver.dev)
As we saw in the opening post, SQLite stores metadata about tables in a special "schema table" starting on page 1. We've been reading records from this table to list the tables in the current database, but before we can start evaluating SQL queries against user-defined tables, we need to extract more information from the schema table.

About A comprehensive guide for Linux Network (Socket) programming (github.com/nguyenchiemminhvu)
In my opinion, Linux network programming, especially socket programming, isn’t that difficult. However, learning this topic on your own can be challenging because many online resources are unclear, and sample codes often only cover the basics. You might find yourself unsure of what to do next. That's why I created this tutorial. It aims to give you clear guidelines and plenty of examples to help you understand better.
