    Corsair

    Corsair

    Your Agent's Integration Layer

    ...A permission system can allow, require approval for, or block read, write, and destructive operations. Credentials are resolved internally and can be stored with envelope encryption rather than passed into model context. Multi-tenant mode isolates each tenant's credentials, data, and permission evaluation. Plugins can also provide signature-verified webhooks through a shared endpoint. Corsair is designed for production agent systems that need OAuth, scoped authorization, human approval, and centralized integration control.

    Napkin Math

    Napkin Math

    Techniques and numbers for estimating system's performance

    Napkin Math is a technical reference project for estimating software system performance from first principles. It collects practical numbers, benchmark-style measurements, and mental models that help engineers make fast back-of-the-envelope calculations. The project is useful for questions like how much memory throughput matters, how long storage operations may take, what network latency to expect, or how expensive logging could become at high request volume. It treats these values as rounded numbers for reasoning rather than exact performance guarantees. The repository is especially useful for system design interviews, architecture planning, capacity estimation, and infrastructure cost discussions. ...

    DBD2

    A multi-threaded, multi-database tcp-based database insertion app.

    ...On failure, it backs off and retries until its life-time timer expires. The back-end daemon accepts data from Syslogd2 or its own client and inserts that data (and envelope information) into one or more databases using MySql client library or dbi drivers (also on SourceForge). The client needs no configuration (all input is via command-line). It is intended for hosts to make database entries without needing database client or interface code. Syslogd2 integration allows DBD2 to act as Syslogd2's database back-end for MySql and other databases supported by the dbi drivers. ...
