  • zip-manager

    Progressive Web App for creating, reading, and editing zip files

    Project mention: Zip Manager | /r/PWA | 2023-04-16

    Hi, I spent some time coding a demo for the zip.js library I wrote. In the end, the application is quite functional and I thought that it could be interesting for other people. The source code is on GitHub here: I hope you enjoy it, feedback is also welcome :)

  • blackjack-basic-strategy

    A computer vision powered Blackjack basic strategy app powered by Roboflow.

    Project mention: Show HN: Pip install inference, open source computer vision deployment | | 2023-08-23

    It’s an easy to use inference server for computer vision models.

    The end result is a Docker container that serves a standardized API as a microservice that your application uses to get predictions from computer vision models (though there is also a native Python interface).

    It’s backed by a bunch of component pieces:

    * a server (so you don’t have to reimplement things like image processing & prediction visualization on every project)

    * standardized APIs for computer vision tasks (so switching out the model weights and architecture can be done independently of your application code)

    * model architecture implementations (which implement the tensor parsing glue between images & predictions) for supervised models that you've fine-tuned to perform custom tasks

    * foundation model implementations (like CLIP & SAM) that tend to chain well with fine-tuned models

    * reusable utils to make adding support for new models easier

    * a model registry (so your code can be independent from your model weights & you don't have to re-build and re-deploy every time you want to iterate on your model weights)

    * data management integrations (so you can collect more images of edge cases to improve your dataset & model the more it sees in the wild)

    * ecosystem (there are tens of thousands of fine-tuned models shared by users that you can use off the shelf via Roboflow Universe[1])

    Additionally, since it's focused specifically on computer vision, it has specific CV-focused features (like direct camera stream input) and makes some different tradeoffs than other more general ML solutions (namely, optimized for small-fast models that run at the edge & need support for running on many different devices like NVIDIA Jetsons and Raspberry Pis in addition to beefy cloud servers).


  • WorkOS
