This catalogue covers small Ruby libraries, Rails integrations and native-extension experiments. Support labels describe their present maintenance state; repository version numbers and historical minimum requirements do not imply compatibility with a current Ruby or Rails release.
Ruby Gems and Native Extensions
simd_string_upcase
A native extension that accelerates ASCII String#upcase with AVX, AVX2, SSE2 or ARM NEON and falls back to Ruby for other input.
- Type
- Native extension
- Repository version
- 0.1.10
- Support status
- Active experiment
- Last tested
- Ruby 4.0.6 on Apple silicon with NEON; historical benchmarks use Ruby 3.3 on Intel AVX2 and Ruby 3.4.2 on Apple M4.
Compatibility note: It globally replaces String#upcase and requires a working native compiler. Benchmark results are hardware-specific; validate correctness and performance on the target Ruby, OS and CPU before use.
last_tweet_redux
A small daemon that fetched the latest tweet for an account, formatted it and stored it in Redis for another application to read.
- Type
- Ruby service gem
- Repository version
- 0.1.3
- Support status
- Legacy / unsupported
- Last tested
- Ruby 3.4.7 locally; CI is configured for Ruby 3.2, 3.3, 3.4 and 4.0.
Compatibility note: The integration still targets Twitter API v1.1 and has no live X API or Redis integration coverage. Treat it as source material, not a current X client.
murmur_redux
A native C extension exposing MurmurHash3 digests through a small Ruby API.
- Type
- Native extension
- Repository version
- 1.0.4
- Support status
- Historical / unsupported
- Last tested
- Ruby 4.0.6 on arm64 macOS 25.6 with Apple Clang 21.0.0.
Compatibility note: Modern Ruby C APIs, compilers, operating systems and CPU architectures are unverified. MurmurHash is non-cryptographic and must not be used for passwords, signatures or other security decisions.
search_redux
An Active Record concern providing PostgreSQL full-text search and a basic fallback for other relational databases.
- Type
- Rails integration gem
- Repository version
- 1.0.4
- Support status
- Maintained / narrow support
- Last tested
- Ruby 4.0.6 with Rails 8.1.3.1 and SQLite 3.51.2; PostgreSQL SQL generation is unit-tested without a live server.
Compatibility note: Support is intentionally limited to Rails 8.1. PostgreSQL execution, query plans and index usage still require validation against the target production database.
