Haunted AI: Whispers of Blackthorn Manor, a Local Qwen-Powered Detective Game

·12 views

Haunted AI: Whispers of Blackthorn Manor is a supernatural detective browser game in which a 1926 death draws the player into a mansion a century later. Three ghosts, Eleanor, Thomas and Clara, each recall different parts of the night, so the player must gather evidence across six rooms, collect eight clues, reconstruct a torn letter and connect findings on a detective board. The game ends with a submitted theory and one of three endings: Truth Revealed, Partial Truth or False Accusation. Its AI gives each ghost a limited, consistent perspective, with dialogue generated by the locally run open-weight qwen2.5:1.5b model through Ollama while the backend enforces game rules. The project was built as a submission to the Hacktoberfest Open-Source AI Challenge and is published as open source under the MIT license.

FINDR AI Open-Source Tool Targets GPS Spoofing in Parcel Delivery Tracking

FINDR AI is an open-source system built to detect suspicious location manipulation in e-commerce parcel delivery, where GPS coordinates can be misleading. It flags GPS spoofing, physically impossible teleportation jumps, and gradual location drift, then assigns risk scores to suspicious telemetry. The system adds investigation workflows, human approval for critical rescue actions, and hash-chain audit logging for traceable decisions. Built in Python with Streamlit, FastAPI, MongoDB Atlas, and SQLite, it was submitted to the Hacktoberfest Open-Source AI Challenge and reports 105 passing regression tests.

Debugging Malformed JSON From an Email Send API After Payment

The article advises validating the exact request payload against the provider's documented schema before sending, rather than assuming the response is at fault. It recommends checking the HTTP status before parsing the body, since an HTML gateway error or empty response can cause a JSON decoding failure. Retries should use a stable idempotency key and a policy keyed to status codes, to avoid duplicate sends and redundant payloads. The author also proposes splitting retention, keeping operational metadata and a payload hash longer while shortening retention of sensitive receipt content. The overall guidance is to log request bytes, status, content type, and a size-limited raw body separately from parser errors.

Measuring a Server: Latency Knees, Misleading Percentiles, and Little's Law

The author built a deliberately simple single-worker server to study how latency behaves under load. Ramping request rates revealed a 'knee' where tail latency rises sharply well before the server is fully utilised. At about 70% busy, the 99th percentile latency had already more than doubled. The author also argues that averages hide slow outliers, so percentiles better reflect what users actually experience. A further experiment showed that fan-out amplifies this effect, since a page is only as fast as its slowest dependency.

Developer Struggles With Calculator App Logic, Plans to Resume Work Tuesday

A developer posting on DEV Community says they are stuck on the logic of a calculator app they are building. They plan to continue the project on Tuesday because they have other commitments on Monday. The developer had expected the task to be simple but found it more difficult than anticipated. They recalled previously building a basic calculator webpage with AI assistance in about half an hour, and reflected that they have not retained the earlier learning.
