This is a monorepo/ecosystem of software/hardware solutions built by Dennis. Code is written primarily in Rust. Check out the partial list of what's available below.

To get started using the existing applications in this repo, follow the user guide.

Licensing

Files in this repository are licensed according to the terms in the LICENSE file though sub-directories may contains separate LICENSE files that overrule this for all files in that sub-directory.

In short, all the software is licensed under an Apache 2 license and hardware is licensed with the CERN OHL v2 Permissive license.

Components

Systems

• Cluster Orchestration : Kubernetes/Borg like containerization and service mesh solution.
• Metadata Storage : Chubby/Etcd like key-value store.
• Builder : A Bazel/Buck like dependency graph based build system.

Libraries

• Executor: Runtime for executing async futures.
• CLI Arguments Parser
• Cryptography: Suite of most common encryption/hashing/randomness algorithms. Also includes support for TLS and X.509.
• HTTP: HTTP 1/2 client/server implementation.
• RPC: gRPC compatible remote procedure call framework.
• Math: Linear algebra, optimization, geometric algorithms, big integers, etc.
• Compression
• Linux Syscall Bindings
• USB Device/Host Driver
• JSON
• Image Encoding/Decoding
• Raft : Implementation of Raft consensus and everything need to make a replicated state machine from an existing non-replicated one.
• Embedded DB : A LSM style single process database compatible with RocksDB/LevelDB.
• Graphics : A UI and rendering framework.

Compilers

• Automata / Regular Expressions
• Protobuf: Support for serialization/deserialization of Protocol Buffers either via code generation or dynamic reflection.
• ASN.1: Compiler for safe accessors and serialization/deserialization of ASN.1 messages.
• Markdown
• Skylark: Python like evaluation.

Directory Structure

Directories under this repository are used as follows:

• pkg/[name](/[subname])* : First party Rust crates
• doc/ : General documentation not associated with any specific package
• testdata/ : Data for testing stuff under pkg/
• third_party/ : Code and data dependencies imported from external sources (not written originally in this repository).
  • Code that interfaces with external services/devices may still exist in pkg/
  • As a general rule of thumb, we'd prefer to clone any dependencies into here rather than relying on package manager based vendoring.
