Developer Builds Voice-Driven Murder Mystery Game Using OpenAI Real-Time AI

·1 views

A developer has launched a voice-driven murder mystery game where players interrogate AI suspects using speech-to-speech technology powered by OpenAI's gpt-realtime-2.1 model over WebRTC. The project was originally conceived two to three years ago but has been rebuilt now that voice AI technology has matured sufficiently. Due to the high cost of the underlying AI model, access is restricted to authenticated users via Clerk, and sessions are capped at 30 minutes. When a player makes a direct accusation, a separate GPT-mini judge evaluates whether the player genuinely presented the required evidence, with paraphrasing accepted but vague guesses rejected. The game's tech stack includes Next.js, MongoDB, and Clerk, and the creator has shared it on Hacker News for public testing and feedback.

Zero-Budget Framework for Benchmarking AI Coding Models on Side Projects

A developer has published a structured, repeatable workflow for evaluating AI coding assistants without spending money, using free-tier APIs and a disposable git repository. The method replaces the common "vibes-based" approach — testing a model with one prompt and judging it on that alone — with a reusable benchmark suite of five to eight task types. A minimal Python harness captures raw model responses, timestamps, and errors for offline comparison across multiple models and runs. The workflow is designed to be provider-agnostic, removing barriers like API costs and the need for local hardware capable of running large models. By versioning prompts and never tuning them to favour a specific model, the approach aims to surface genuine strengths and weaknesses before any real-world deployment.

Velero Backup Bug: Kubernetes Tool Silently Omitted PVC Data for Weeks

A homelab operator discovered on June 19, 2026, that Velero had been reporting successful daily backups while never actually capturing any PersistentVolumeClaim data. The tool defaulted to snapshot-based backups, which require a CSI snapshot provider — something NFS and local-path storage classes do not support. Without a snapshot provider, Velero silently backed up only Kubernetes manifests, omitting all application data including Postgres databases, Vaultwarden passwords, and Nextcloud files. The issue was fixed by adding a single line — defaultVolumesToFsBackup: true — to the backup schedule, switching Velero to filesystem-based backup via Kopia, after which backup size jumped from roughly 2 MB to 4 GB. The operator noted that running 'velero backup describe --details' and checking the 'Pod Volume Backups' field is the only reliable way to confirm actual PVC data was captured.

New Tool Converts Dynamics 365 Task Recordings into Structured Markdown Guides

A developer tool called axtr-to-markdown automates the conversion of Microsoft Dynamics 365 Task Recorder exports into editable Markdown documents. The skill processes recorded user steps, form names, field controls, and action types to produce structured Level 3 or Level 4 process documentation. Output includes sections for purpose, scope, prerequisites, troubleshooting, and a SIPOC analysis draft, reducing manual transcription work for teams. Functional consultants and process owners can then review and enrich the generated draft rather than building documentation from scratch. The tool is designed to support use cases such as end-user training, onboarding guides, UAT test scripts, and SharePoint knowledge articles.
