    DuplicateBridge

    DuplicateBridge

    A project to automate the production of hands for Duplicate Bridge

    Duplicate bridge is a variation of contract bridge where the same set of bridge deals (i.e. the distribution of the 52 cards among the four hands) are played by different competitors, and scoring is based on relative performance. In this way, every hand is played in competition with others playing identical cards, and the element of skill is heightened. This stands in contrast to Bridge played without duplication, where each hand is freshly dealt and where scores may be more affected by chance in the short run. ...

    Cancelable Async Flows

    Cancelable Async Flows

    Cancelable Async Flows (CAF)

    ...This approach avoids brittle timeouts and “fire-and-forget” leaks by making cancellation a first-class concern. CAF is framework-agnostic and pairs well with fetch, timers, or custom async primitives, giving you a consistent contract for stopping in-flight operations. The result is safer UI interactions and services that don’t keep doing work the user no longer needs.

    IPFS Submarine

    IPFS Submarine

    Bash commands to submarine folders and files on the IPFS

    ...Submarining is the process of obtaining and publishing an IPFS folder without publishing the files contained within the folder. This is useful for, for example, an NFT project using the OpenZeppelin ERC721 contract, where images are enumerated. The scripts set up two instances of the IPFS, one which is kept private, and one which is a public gateway out to the rest of the IPFS. The image folder is added and pinned in the private IPFS swarm, and then commands are avaialbe for copying parts but not all of the files underlying a folder to the public gateway.

    Cnry

    Cnry makes it easy to publish and keep track of warrant canaries

    ...Even if you don't need a warrant canary, you can publish a Cnry as a pet that you need to feed once in a while (via the keepalive function) or it will expire. How often you need to feed it is configurable in the contract. Warrant canaries are only useful if someone's paying attention. So anyone can call the watch function which will mint a WATCHER nft that keeps track of that activity. I have some further features in the works that will expand on that concept.
