Polymarket copy-trading bot survives outage with triple-trade detection system

·1 views

A developer maintains Garnet, a self-hosted copy-trading engine for the prediction market Polymarket. Following a platform-wide websocket outage in August 2026, the bot was redesigned with three independent methods to detect trades. It now monitors trades via a real-time websocket, a slow REST API poll, and directly from blockchain events on Polygon. This multi-layered approach ensures detection continues even if one data source fails, with all signals deduplicated into a single, reliable output.

Tessvia tool generates four deliverables from single user-scenario script

Tessvia is a service that allows developers to write a single set of user actions, known as a scenario. From this one source, it mechanically generates four distinct outputs: tutorial playback, automated manual generation, end-to-end tests, and liveness monitoring. This approach aims to eliminate the need to write and maintain the same operational logic separately for each deliverable. The tool was built to prevent inconsistencies that arise when changes are made to one output but not the others. It uses plain language steps, enabling step-by-step execution and branching logic.

Guide details methods to detect and prevent LLM factual errors in responses

An article on DEV Community outlines techniques to address a specific type of LLM error where a model confidently misinterprets source information. The proposed solution involves a three-step guardrail system of grounding answers in retrieved sources, scoring response trustworthiness, and applying a fallback action. This system includes a critical verification step where factual claims in a generated answer are checked against cited source passages before delivery. The guide emphasizes that retrieval alone is insufficient and that the entire pipeline, including the verification model, must be evaluated together to manage residual errors.

Developer details switch from Windows to Fedora Linux for a quieter workflow

The author emphasizes this is a personal preference, not a critique of Windows, and encourages others to try Linux. After four months, he reports greater focus and a more intentional, privacy-conscious approach to software.
