Why the heck are we still using Markdown?

You're frustrated with Markdown's complexity and inconsistencies, particularly with inline HTML and multiple ways to write the same thing. You think a minimal, well-defined markup language with a build system and compile-time hooks could solve many problems.

We replaced RAG with a virtual filesystem for our AI documentation assistant

https://www.mintlify.com/_next/image?url=%2Fimages%2Ffeatured%2Fhow-we-built-a-virtual-filesystem-for-our-assistant.png&w=1920&q=75
The team created a virtual filesystem called ChromaFs to power their documentation assistant, allowing it to explore documentation like a codebase without the need for real sandboxes. ChromaFs uses a Chroma database to provide instant session creation, zero marginal compute cost, and built-in role-based access control, replacing the need for expensive sandboxes.

SSH certificates: the better SSH experience

SSH certificates provide a better and more seamless SSH experience by eliminating the need for Trust on First Use (TOFU) and allowing for short-lived keys, forced-commands, and automated key management. An SSH CA can be used to sign host keys and user keys, making it easier to manage SSH connections and eliminating the need for manual key deployment and TOFU.

What Category Theory Teaches Us About DataFrames

The author analyzes the structure of dataframes and identifies three fundamental operations: Delta (restructuring), Sigma (merging), and Pi (pairing), which can be used to build a dataframe algebra. Category theory provides a framework for understanding these operations and their relationships, allowing for a more principled design of dataframe libraries.

Category Theory Illustrated – Types

https://abuseofnotation.github.io/category-theory-illustrated/06_type/zfc_pairing.svg
Type theory is a mathematical theory that is an alternative to set theory and category theory, and it is used to define collections of objects that are interesting without accidentally defining collections that lead to paradoxes. Type theory is based on the idea that the interesting collections are the source and target of functions, and it is used to define types and functions in a way that ...
