Linux Kernel
Linux Kernel source tree
The Linux Kernel is the core component of the Linux operating system—a free, open-source, monolithic, Unix-like system kernel initiated by Linus Torvalds in 1991 and since evolved into a foundational technology powering everything from servers and supercomputers to smartphones and embedded devices. There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation. -

Flash Linux 0.11 Talk
Annotated Unix system source code
flash-linux0.11-talk is an annotated walkthrough of the Linux 0.11 kernel that explains how a tiny Unix-like system boots, schedules, handles interrupts, and manages memory. The materials break down historically compact and dense code into digestible segments, with diagrams and call flows that trace execution from bootloader to user space. By focusing on a small, early kernel, the series reveals core OS concepts without the complexity of modern subsystems. -

Zapret
Advanced open source tool for bypassing DPI-based censorship
Zapret is an open source, cross-platform tool designed to help users bypass and evade Deep Packet Inspection (DPI)-based traffic blocking and censorship systems. Rather than acting as a traditional proxy or VPN, it works by manipulating network packets and traffic streams locally to confuse or disrupt DPI mechanisms used by ISPs and network filters, making it possible to access restricted websites and services without relaying traffic through third-party servers. Zapret implements multiple... -
