Recent releases

The latest release of each repository, read from GitHub on 2026-09-29. Each title links to the write-up, or to the repository where there is no write-up yet.

  • Streams Ride Matcher
    dispatchgrid · v5.2.0, 2026-09-29
    Ride matching on Kafka Streams in Java 21 and Spring Boot 3, with trips in city-keyed MySQL shards, driver positions in Redis GEO and zero-downtime rolling updates on Kubernetes.

  • CUDA Kernel Fuzz Tester
    kernelcheck · v4.0.0, 2026-09-29
    Differential fuzz tester for CUDA C++ kernels on a CPU execution model, never run on a GPU; it detected 156 of 171 seeded mutants, and the 15 it missed are equivalent under the kernels' contracts.

  • Expert Grading And Delivery Platform
    panelist · v6.0.0, 2026-09-28
    Expert grading platform: tasks routed by expertise tag, hidden attention checks, pay per approved task, and approved grades exported as versioned, checksummed JSONL datasets.

  • Ownership And Exposure Graph
    tradegraph · v5.1.1, 2026-09-28
    Counterparty knowledge graph from SEC filings: a Python ETL loads RDF into a SPARQL store, a Spring Boot API answers lineage and exposure queries, and an Angular explorer draws it.

  • Declarative Connector Pipeline
    conduit · v6.0.0, 2026-09-28
    Connector kit with one adapter interface for Slack, Jira and signed webhooks: idempotency keys, backoff, a circuit breaker per connector and an SQS dead-letter queue.

  • Collective Fault Injection Harness
    rankfault · v5.0.0, 2026-09-28
    Fault injection for multi-rank PyTorch jobs: kills, freezes, link faults and ordering skew injected mid-collective; measured with gloo on CPU on Linux, 0 of 114 runs stalled, NCCL never run.

  • ETA Model Serving
    modelgate · v5.0.1, 2026-09-27
    FastAPI serving for a PyTorch ETA model: strict input validation, shadow runs, canaries with automatic rollback, and version swaps load-tested with 0 dropped requests.

  • Resilient API Gateway
    failsafe · v5.0.1, 2026-09-27
    Python API gateway with token-bucket rate limiting, per-replica circuit breakers, retries and failover; its chaos runs kill replicas under load with zero client-visible failures.

  • Signed Webhook Integration Service
    launchbridge · v5.1.0, 2026-09-27
    FastAPI and PostgreSQL integration service: signed inbound webhooks, deduplication, bounded retries, replay of failed events and secret rotation.

  • Procedure To Agent Pipeline
    playbook · v6.0.0, 2026-09-27
    Turns an expert's walkthrough and SOP into a tool-calling agent with Jira and Slack tools, grades its runs against the expert's rubric and feeds failures back as corrections.

  • Two-Stream Spoof Detection
    spoofline · v5.1.0, 2026-09-27
    Audio and video spoof detection with a CNN-LSTM per stream, calibrated and fused, evaluated on attack families held out of training, on a deterministically generated corpus.

  • Notes To Agent Instructions
    expertloop · v5.1.0, 2026-09-27
    Turns expert task notes into versioned agent instructions with linked sources, and gates approved workflows behind test cases before they reach business systems.

  • Order Saga With Chaos Proof
    ledgermesh · v5.0.0, 2026-09-10
    Order saga across three Spring Boot services with Kafka, Redis and Resilience4j; in the recorded chaos run, 1200 orders under three service kills ended with none failed or stuck.

  • Ride Dispatch Platform
    rideloop · v5.0.0, 2026-09-08
    Ride request, driver location and dispatch services in Python, with a geohash-partitioned DynamoDB driver index, PostgreSQL trips and a React rider map.

Open source

1183 merged pull requests in projects outside this account (as of 2026-09-29) across the JavaScript, Python, Go, and Rust ecosystems. Until May 2026 the approach was volume; since May 5, 2026 it is one issue at a time: reproduce it, fix it, test it, and land a single clean change. Apologies to the maintainers who dealt with duplicate or half-tested PRs before that.
