    FairScale

    FairScale

    PyTorch extensions for high performance and large scale training

    ...The library also provides pipeline parallelism, activation checkpointing, mixed precision, optimizer state sharding (OSS), and auto-wrapping policies that reduce boilerplate in complex distributed setups. Its components are modular, so teams can adopt just the sharding optimizer or the pipeline engine without rewriting their training loop. FairScale puts emphasis on correctness and debuggability, offering hook points, logging, and reference examples for common trainer patterns. Although many ideas have since landed in core PyTorch, FairScale remains a valuable reference and a practical toolbox for squeezing more performance out of multi-GPU and multi-node jobs.

    A list of funny and tricky JavaScript examples

    WTFJS is a curated collection of JavaScript “gotchas” and puzzling examples that reveal surprising corners of the language. Each entry presents a small snippet, explains why the behavior occurs, and ties it back to the specification or engine rules. The repository covers coercion quirks, edge-case comparisons, floating-point oddities, prototype traps, and scoping pitfalls, among others. It’s designed as both a fun read and a serious learning aid, helping developers build an intuition for how JavaScript evaluates expressions. By highlighting common misconceptions, it encourages safer coding patterns and more reliable mental models. ...

    OpenGL ES to Metal API translation layer

    metalangle is a Metal-backed implementation of ANGLE (Almost Native Graphics Layer Engine), allowing OpenGL ES applications to run on Apple platforms by translating their calls into Metal, Apple’s proprietary low-level graphics API. This makes it possible to run cross-platform OpenGL ES content on iOS and macOS with high performance and compatibility. It is particularly valuable for developers porting games and engines to Apple devices, where OpenGL is deprecated and no longer hardware-accelerated.

    Javascript/WebGL lightweight face tracking library

    ...We provide various demonstrations using main WebGL 3D engines. We have included in this repository the release versions of the 3D engines to work with a determined version (they are in /libs/<name of the engine>/). This library is lightweight and it does not include any 3D engine or third-party library. We want to keep it framework agnostic so the outputs of the library are raw, if the face is detected or not, the position and the scale of the detected face and the rotation Euler angles. But thanks to the featured helpers, examples and boilerplates, you can quickly deal with a higher level context (for motion head tracking, for face filter or face replacement). ...

    Open HTML to PDF is a pure-Java library for rendering a reasonable subset of well-formed XML/XHTML (and even some HTML5) using CSS 2.1 (and later standards) for layout and formatting, outputting to PDF or images. Use this library to generated nice looking PDF documents. But be aware that you can not throw modern HTML5+ at this engine and expect a great result. You must special craft the HTML document for this library and use it's extended CSS feature like #31 or #32 to get good results. Avoid floats near page breaks and use table layouts.
