Building & Running

NOTE: This has only been tested in an emulator. Real hardware might not like it.

EDIT: this is not true anymore! @parkerlreed has run this on a Thinkpad T510.

Mac OS

For the cross-compiler: $ brew tap nativeos/i386-elf-toolchain && brew install i386-elf-binutils i386-elf-gcc

$ make iso$ qemu-system-i386 -drive format=raw,file=boot.iso -d cpu_reset -monitor stdio -device sb16 -audiodev coreaudio,id=coreaudio,out.frequency=48000,out.channels=2,out.format=s32

Unix-like

You should not need a cross-compiler in most cases as the gcc shipped in most linux distros will support i386 targets.

If this isn't the case for you,

Overview

Taichi () is a programming language designed for high-performance computer graphics. It is deeply embedded in Python, and its just-in-time compiler offloads compute-intensive tasks to multi-core CPUs and massively parallel GPUs.

Advanced features of Taichi include spatially sparse computing and differentiable programming [examples].

Please check out our SIGGRAPH 2020 course on Taichi basics: YouTube, Bilibili, slides (pdf).

Installation

python3 -m pip install taichi

Supported OS: Windows, Linux, Mac OS X; Python: 3.6/3.7/3.8 (64-bit only); Backends: x64 CPUs, CUDA, Apple Metal, OpenGL Compute Shaders.

Please build from source for other configurations (e.g., your CPU is ARM, or you want to try out our experimental C backend).

Note:

• The PyPI package supports x64 CPU, CUDA 10/11, Metal, and OpenGL Compute Shader

Netdata is high-fidelity infrastructure monitoring and troubleshooting.
Open-source, free, preconfigured, opinionated, and always real-time.

Netdata's distributed, real-time monitoring Agent collects thousands of metrics from systems, hardware, containersand applications with zero configuration. It runs permanently on all your physical/virtual servers, containers, clouddeployments, and edge/IoT devices, and is perfectly safe to install on your systems mid-incident without anypreparation.

You can install Netdata on most Linux distributions (Ubuntu, Debian, CentOS, and more), container platforms (Kubernetesclusters, Docker), and many other operating systems (FreeBSD, macOS). No sudo required.

Netdata is designed by system administrators, DevOps engineers, and developers to collect everything, help you visualizemetrics, troubleshoot complex performance problems, and make data interoperable with the rest of your monitoring stack.

People get addicted to Netdata. Once you use it on your systems, there's no going back! You've been warned...

License & Intended use

This is an art project, not a software tool for music creation. I consider it to be finished, and as such I will likely not be accepting feature requests or feature-driven PRs. Please feel encouraged to fork the project and do something else with it if you would like - I love to see further creative work built on top of it.

Zellij

What is this?

Zellij is a workspace aimed at developers, ops-oriented people and anyone who loves the terminalAt its core, it is a terminal multiplexer (similar to tmux and screen), but this is merely its infrastructure layer.

Zellij includes a layout system, and a plugin system allowing one to create plugins in any language that compiles to WebAssembly.

For more details about our future plans, read about upcoming features in our roadmap.

Zellij was initially called "Mosaic".

How do I install it?

You can install it through cargo:

cargo install zellij

Or you can download a prebuilt binary from our Releases.

How do I hack on it?

• Clone the project
• Install cargo-make with cargo install --force cargo-make
• In the project folder, run: cargo make run

For more build commands, take a look at Contributing.md.

Configuration

For configuring Zellij, please see the Configuration

F: A Flight-Proven, Multi-Platform, Open-Source Flight Software Framework

F (F Prime) is a component-driven framework that enables rapid development and deployment of spaceflight and other embedded software applications. Originally developed at the Jet Propulsion Laboratory, F has been successfully deployed on several space applications. It is tailored but not limited to small-scale spaceflight systems such as CubeSats, SmallSats, and instruments.

Please Visit the F Website: https://nasa.github.io/fprime/. This website contains project information, user guides, documentation, tutorials, and more!

F comprises several elements:

• An architecture that decomposes flight software into discrete components with well-defined interfaces
• A C++ framework that provides core capabilities such as message queues and threads
• Modeling tools for specifying components and connections and automatically generating code
• A growing collection of ready-to-use components
• Testing tools for testing flight software at the unit and integration levels.

Quick Installation Guide

The following utilities are prerequisites to installing F:

• cmake
• git
• Python

Corona Warn App - Android

Development Documentation Contribute Support Changelog Licensing

The goal of this project is to develop the official Corona-Warn-App for Germany based on the exposure notification API from Apple and Google. The apps (for both iOS and Android) use Bluetooth technology to exchange anonymous encrypted data with other mobile phones (on which the app is also installed) in the vicinity of an app user's phone. The data is stored locally on each user's device, preventing authorities or other parties from accessing or controlling the data. This repository contains the native Android implementation of the Corona-Warn-AppVisit our FAQ page for more information and common issues
