TuxClocker
Qt overclocking tool for GNU/Linux
TuxClocker is an open-source Qt-based overclocking and hardware monitoring utility tailored for GNU/Linux systems. The project combines a DBus daemon with a Qt graphical user interface, allowing users to inspect and adjust performance characteristics of their hardware—particularly GPUs—under Linux. TuxClocker provides a user-friendly GUI atop lower-level interfaces, making it easier to control clock speeds, fan behavior, and other tuning parameters without resorting exclusively to command-line tools. It is especially useful for Linux enthusiasts and power users looking to optimize performance for gaming, content creation, or benchmarking. The project also has a companion command-line version (tuxclocker-cli), broadening usability scenarios for scripting or headless setups. While the features and hardware support may vary by distribution and driver stack, TuxClocker fills a niche for integrated Linux performance tuning with a polished front end. -

WINIX OS
A UNIX-style Operating System for the Waikato RISC Architecture
Winix is an experimental Unix-like operating system kernel written in modern C++ with an emphasis on object-oriented design and code clarity. It is a pedagogical project exploring how kernel-level programming can be structured with C++ abstractions while maintaining low-level control. Winix supports basic system services such as file systems, process management, and a terminal interface, and is designed for booting on x86_64 hardware via QEMU. It serves as an accessible and unconventional approach to understanding operating systems. -

kallisto
Near-optimal RNA-Seq quantification
kallisto is a program for near-optimal quantification of transcript abundances from RNA-Seq data, or more generally of target sequences using high-throughput sequencing reads. It is based on the idea of using pseudoalignment to quickly determine reads and targets’ compatibility, with no need for alignment. According to benchmarks done on a Mac desktop computer, kallisto can quantify 30 million human bulk RNA-seq reads in less than 3 minutes with just the read sequences and a transcriptome index, that in itself can take more than 10 minutes to build. And since it uses pseudoalignment, it is robust to errors in the reads and preserves the key information needed for quantification. This makes kallisto not only fast but highly accurate as well. In many benchmarks, it even greatly outperforms existing tools. -

nexmon
The C-based Firmware Patching Framework for Broadcom/Cypress WiFi Chip
The C-based Firmware Patching Framework for Broadcom/Cypress WiFi Chips enables Monitor Mode, Frame Injection, and much more. Nexmon is our C-based firmware patching framework for Broadcom/Cypress WiFi chips that enables you to write your own firmware patches, for example, to enable monitor mode with radiotap headers and frame injection. This repository mainly focuses on enabling monitor mode and frame injection on many chips. A real Wi-Fi jammer that allows to overlay ongoing frame transmissions with an arbitrary jamming signal. It uses the Wi-Fi chip as a Software-defined Radio to generate jamming signals. It allows using non-standard channels such as 80 MHz bandwidth in the 2.4 GHz bands. It allows to set of arbitrary transmission powers. It allows patching the D11 core's real-time MAC implementation. It allows to extract of CSI of up to 4x4 MIMO transmissions at 80 MHz bandwidth. -

pg_cron
Run periodic jobs in PostgreSQL
pg_cron is a PostgreSQL extension that allows SQL jobs to be scheduled using cron syntax. It runs inside the database server and lets users automate routine tasks like VACUUM, backups, and custom SQL scripts. Jobs are managed via SQL commands and can run on the same schedule format as standard UNIX cron, making it powerful and easy to use for database administrators and developers alike. -

pglogical
Logical Replication extension for PostgreSQL
pglogical is an advanced logical replication extension for PostgreSQL that allows selective replication of data between databases. Unlike physical replication, it enables fine-grained control of which tables or changes to replicate. It’s well-suited for multi-master setups, version upgrades, and real-time data distribution across environments. -

raspberry-pi-os
Learning operating system development using Linux kernel and Raspberry
This project provides a step-by-step educational guide on building a simple operating system kernel entirely from scratch, specifically targeting the Raspberry Pi 3. The operating system, referred to as RPi OS, is inspired by the Linux kernel but remains intentionally minimal to focus on clarity and teaching fundamental OS concepts. Each lesson introduces a kernel feature and demonstrates its implementation within RPi OS, followed by a comparison to how the same concept is realized in the Linux kernel. The repository is structured so that every lesson corresponds to a snapshot of the source code at that stage, making it easier for learners to follow the progression of kernel development. The design of the lessons emphasizes gradual learning, allowing readers without prior OS development experience to understand kernel internals. The project is still under active development and encourages community contributions to expand its lessons and improve its content. -

raylib-go
Go bindings for raylib, a simple and easy-to-use library
raylib-go is a Go (Golang) binding/wrapper around raylib, the light-weight C library for video game and multimedia programming. It allows Go developers to build 2D (and some simple 3D) games, graphical applications, or multimedia tools using a familiar and simple API, while leveraging Go’s language ergonomics, concurrency model, and ecosystem. With raylib-go, developers can draw graphics, handle input, play sound, manage textures, and manage game loops directly in Go — without needing to write or interface with C manually. This makes it a good choice for those who prefer Go over C/C++, but still want a simple, straightforward engine for fast prototyping or small-to-medium games. Because raylib is known for simplicity and ease of use, raylib-go carries that over to the Go ecosystem: you can get up and running quickly, which is ideal for hobbyist developers, game jams, prototypes, or small indie games. It bridges the gap between performance and convenience. -
