Rust Go Python JavaScript Repositories

Built from the lowest layer that makes the problem honest: kernel accounting instead of sampling, measured results instead of claims, one binary instead of a stack.

Flagship

FalconDB

FalconDB  Rust

A columnar analytical database engine written from scratch: storage, encodings, planner, executor, indices, WAL and the SQL front end. Benchmarked against DuckDB, DataFusion and Polars, with the method and numbers in the repository.

netwatch  Rust

Which program is using your connection, and how much. Reads the kernel's own accounting (ETW on Windows, eBPF on Linux) instead of sampling.

synchronize  Go

Keeps every git repository in step across every machine you work on: sync at login, on a timer and before shutdown. Windows, Linux and macOS builds in Releases.

falconnet  Rust

SQL, diagnostics and per-process attribution over packet captures: Wireshark that answers questions.

Developer tools

Small tools that each answer one question, with measured results.

Tool What it answers
sql-traps The same SQL on MySQL, MariaDB, PostgreSQL and SQL Server in Docker: where the results differ, with versions and dates.
workflow-doctor Where a GitHub Actions workflow loses minutes: per step, retries, cache, critical path, cost.
flakemap-contrib Which new or changed pytest tests are unstable: rerun N times and fail on mixed results.
jest-polluter-finder Which Jest test files make a victim test fail, found by delta debugging.
dockerfile-diff-size Which Dockerfile instruction made the image bigger, layer by layer.

Desktop apps

vk-chain

Chain-of-handshakes finder and interactive friend-network explorer for VKontakte.

mini-player

Floating always-on-top mini windows for YouTube, TikTok, Twitch and video files.

desktop-focus

Hide every desktop icon except the ones you choose, and restore their positions.

Each project has its own README with install steps, limits and how it was measured. Issues and pull requests are welcome.
