Show HN: Note taking and book Library, all-in-one AI KnowledgeBase

Hacker News - Thu, 07/23/2026 - 10:03am

Hi HN,

I built an all-in-one AI KnowledgeBase, using AI with - Note taking - Library and Reading

PileaX is a local-first, all-in-one AI knowledge base that integrates AI chat, smart notes, and e-book reading & management. From knowledge creation to application, PileaX helps you build a unified knowledge base and continuously optimizes the AI interaction experience with AI agent technologies.Your data is fully under your control. It supports offline desktop apps and flexibly deployable web apps.

- Desktop Platform: Windows, macOS, Linux - EBook: EPUB, MOBI, AWZ3, FB2, CBZ, PDF

Show HN: Matlab syntax in Jupyter, client-side

Hacker News - Thu, 07/23/2026 - 10:01am

jupyterlite-numbl-kernel is a JupyterLite kernel for numbl (https://numbl.org). It demonstrates running MATLAB syntax in Jupyter, client-side in the browser (no MATLAB or Octave needed). The live demo is a static site hosted on GitHub Pages... nothing to install:

https://concept-collection.github.io/jupyterlite-numbl-kerne...

Numbl is a lightweight (TypeScript + wasm + optional native bridge to OpenBLAS) numerical computing environment that tries to be as compatible as possible with MATLAB syntax. It has 500+ built-in functions and runs both in the browser and on the command line. I am developing it with Dan Fortunato at the Flatiron Institute.

Why do this? There are many codebases that are written exclusively in MATLAB, require a MATLAB license, and cannot be run client-side in the browser. One such example is chebfun (https://www.chebfun.org/), whose heavy use of MATLAB's object-oriented features means it does not run on Octave. Right now, numbl is mature enough to run most of Chebfun. The capabilities will expand over time as we implement more builtins.

I make a lot of static web applications (many of them proofs of concept) and I love trying to get code to run client-side in the browser. I think it's great for teaching, sharing ideas and methods, and communicating science with interactive views.

Caveat: numbl of course is not MATLAB. It covers a large, tested subset of the language though.
