llm_cost_tracker offers a privacy-first approach by not storing prompts or responses, allowing teams to track LLM API costs without compromising user data.

The core idea is three separate attribute layers: inputs (what comes in), internals (working state), and outputs (what goes out). Each is a distinct declaration with its own namespace and type checking. Combined with declarative make calls that define action order, the data flow through a service is visible at a glance: class Payments::Process < ApplicationService::Base input :payment, type: Payment internal :charge_result, type: Servactory::Result output :payment, type: Payment make :validate_status! make :perform_request! make :handle_response! make :assign_payment

https://github.com/carter2099/hyperliquid There was no Ruby SDK for the HL API so I made one. This was my introduction to Claude Code and it was awesome. I was able to code with an LLM, stay in the terminal, and still learn something new (WebSockets). I also forked an existing ruby web sockets client gem and made it my own: https://github.com/carter2099/ws_lite. Up next I'll use this SDK to create an automated short rebalancer for my concentrated liquidity pool positions.

We're introducing a new animated map engine built on top of ruby-libgd and libgd-gis. It allows Ruby applications to render real basemaps, draw GIS layers, and animate moving objects (cars, routes, planes) entirely on the backend - no JavaScript or WebGL required.

For the past few months, I've been quietly rebuilding this Telegram bot framework from the ground up with one goal: eliminate the thread management headaches and blocking I/O that plague existing solutions. The Vision: What if building a Telegram bot in Ruby felt as clean and modern as writing a Rails API? What if concurrency was handled for you, deployment was one-click, and multi-step conversations were a first-class feature? That's Telegem.

Grepfruit, a ractor-powered text search gem, adds a programmatic API in v3.2, a count-only mode, and Ruby 4 support.
