    gVisor

    gVisor

    Application Kernel for Containers

    gVisor is an application kernel developed by Google that provides a strong layer of isolation between applications and the host operating system. Written in Go, it implements a Linux-compatible system call interface that runs entirely in user space, creating a secure sandboxed environment for containers. Unlike traditional virtual machines or lightweight syscall filters, gVisor follows a third approach that offers many of the security benefits of virtualization while maintaining the speed, resource efficiency, and flexibility of containers. ...

    Software development for 4Mb portable, using Z80 CPU and AA batteries

    This project is for the portable computer "Cambridge Z88", produced by Sir Clive Sinclair (of ZX Spectrum fame). We continue to support software development (ROM, 3rd party apps on memory cards and desktop applications). We have moved to https://cambridgez88.jira.com/wiki (development, source code and documentation). However, we continue to publish files for download here.

    UniSIMD-assembler

    SIMD macro assembler unified for ARM, MIPS, PPC and x86

    UniSIMD assembler is a high-level C/C++ macro assembler framework unified across ARM, MIPS, POWER and x86 architectures. It establishes a subset of both BASE and SIMD instruction sets with clearly defined common API, so that application logic can be written and maintained in one place without code replication. The assembler itself isn't a separate tool, but rather a collection of C/C++ header files, which applications need to include directly in order to use. At present, Intel...

    libjpeg-turbo

    libjpeg-turbo

    SIMD-accelerated libjpeg-compatible JPEG codec library

    libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals...

    Ancient Linux on Windows

    Building and running ancient Linux on Windows

    While I may have started with Linux 0.11, I've expanded this to include several older relases of the Linux kernel that you can cross compile from Windows, and run on Qemu. I've managed to get the older versions of the software tools running on Windows, so that there is no major invasive source changes, outside of either broken drivers, or massaging the makefiles to find things in the new paths, and calling the appropriate tools where needed. Linux 0.10 is the first oldest version of...

    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. ...

    xplgraph-cpmgsx-dxforth

    An replacement of DXForth's xplgraph.scr library for CP/M

    ...Originally, xplgraph.scr library for DXForth was written to work on DOS systems only enabling point-and-plot graphics on VGA-compatible graphics devices. DXForth port to the 8-bit CP/M operating system lacked similar capability. The aim of this project is to provide an replacement of the original xplgraph.scr library, exposing roughly the same API, enabling graphics in DXForth running under CP/M. This library is written using DXForth's inline assembly (with all of its cryptic syntax) and uses CP/M's GSX interface. Using this interface enables graphical output to either local screen or remote devices connected through a serial port (like Tektronix 4010 text-and-graphics terminal emulator running on PC). ...

    Pattern-based multi/many-core parallel programming framework

    FastFlow is a C/C++ programming framework supporting the development of pattern-based parallel programs on multi/many-core, GPUs and distributed platforms. FastFlow run-time is built upon non-blocking threads and lock-free queues. Thanks to its very efficient CAS-free communication/synchronization support (e.g. few clock cycles core-to-core latency), FastFlow effectively supports the exploitation of fine grain parallelism, e.g. parallel codes managing very high frequency streams on...

    halogenOS test builds (release builds are just a leftover) The test builds and modules are supposed to be only used by our testers. But if you are not a tester, and use these builds anyways, don't expect support if you get problems. You can report the bugs, but you have to be experienced enough to know how to revert back to a working state and how to report bugs and provide logs.
