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.

Async Python Is Secretly Deterministic

https://cdn.prod.website-files.com/672411cbf038560468c9e68f/69ccad5e3c7a9d4e05cffa0a_cac94705.png
To make async Python workflows deterministic, we need to understand the event loop's single-threaded execution model and how tasks are scheduled in FIFO order. By incrementing step IDs before the first await in each step, we can deterministically order steps and ensure consistent execution order during recovery.

A Recipe for Steganogravy

A Python CLI uses neural linguistic steganography to hide data in recipe blog introductions. It encodes data as natural language using arithmetic coding steganography, requiring the same model and prompt for decoding.

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.

Big-Endian Testing with QEMU

https://www.hanshq.net/gfx/header_img_3637.jpg
The terms big endian and little endian refer to the order of a value's bytes in memory, with big-endian storing the most significant part first. QEMU provides a solution to test big-endian systems by emulating a big-endian architecture and cross-compiling code.

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.

Update on the eBay Scam

https://kevquirk.com/content/images/update-on-the-ebay-scam/ebay-email.webp
Last week I wrote about how I thought I was being scammed by someone on eBay. In the post I said the following: I've asked eBay to step in and help resolve the situation, so we will see what happens. But there's a lot of buyer protection on eBay (and rightly so) but there's very little in the way of seller protection, even though I'm not a business. So I have a feeling they ...

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 ...
