How One Developer Built a Battery-Friendly Auto-Silent App Using Geofencing

·1 views

A developer created Muffle, a location-aware Android app that automatically silences a phone when entering predefined zones, after a library embarrassment highlighted the limits of manual mute habits. Initial attempts using GPS polling via LocationManager proved impractical, draining battery within hours or responding too slowly to location changes. The developer switched to Google Play Services' Geofencing API, which delegates location monitoring to the OS and uses a mix of Wi-Fi, cell tower, and GPS signals for efficiency. This event-driven approach replaced constant polling with system-managed boundary detection, significantly reducing battery impact. A key challenge was implementing a dwell-time requirement to prevent repeated toggling caused by signal jitter near zone edges.

SnapMind App Shifts to Agent-Based Architecture in Major Rebuild

SnapMind, a desktop app that binds AI prompts to hotkeys, is undergoing a significant rebuild by its developer. The creator has decided to move away from a prompt-based model toward an agent-based architecture, citing rapid advancements in AI as the motivation. A key upcoming feature will allow users to create custom AI agents and assign them to hotkeys. The developer also plans to replace the current LLM provider service with a more robust solution, as frequent API endpoint changes have made the existing setup difficult to maintain. The latest release, v0.5.5, is available on the project's website and GitHub repository.

DeepSeek Harness Builds Entire Agent Framework as Cordis Plugins, Guide Explains

DeepSeek Harness, currently in Developer Preview, treats every core component — including the model adapter, tool registry, session log, and agent loop — as a Cordis plugin rather than privileged core code. A technical guide published on DEV Community, pinned to commit 141eb6f on the master branch, explains how developers should choose between services, events, effects, profiles, and bundles when extending the framework. Services are recommended for callable capabilities with replaceable providers, while events handle passive observation and effects manage resources that must be cleaned up on unload. GitHub released the dsh-v0.1.0-rc.8 pre-release on August 19, though npm still showed version rc.7 as of August 20, meaning package availability may lag behind source releases. The guide is intended for agent-framework developers and emphasizes that plugin readiness is governed by dependency declarations, not YAML list order, with Cordis managing the full lifecycle from PENDING through ACTIVE to DISPOSED.

LSHIY Campaign Exploited OAuth ROPC and IPv6 to Spray Passwords at Scale

A large-scale password-spraying campaign dubbed LSHIY targeted Microsoft Entra ID tenants by abusing OAuth's Resource Owner Password Credentials (ROPC) flow, which bypasses multi-factor authentication prompts entirely. Attackers harvested credentials from public sources and data leaks, then slowly tested one password against many accounts to avoid triggering lockouts. Over a two-week period, more than 81 million login attempts were recorded, resulting in at least 78 compromised accounts. To evade IP-based detection, the threat actors leveraged BYOIP infrastructure and vast IPv6 address ranges linked to entities such as LSHIY LLC, FranTech, and Tor exit nodes. No post-compromise activity was confirmed, suggesting the operation may have been focused on credential validation or resale rather than immediate exploitation.

One Complex Query Beats Ten Simple Ones for Testing PostgreSQL-ChatGPT Connections

When connecting PostgreSQL to ChatGPT, developers should not rely on multiple easy questions with plausible-sounding answers to validate the integration. A single well-designed business query — incorporating a known answer, tenant boundary, join, versioned metric, and a defined reporting cutoff — provides a far more rigorous acceptance test. The test should also verify identity, data freshness, query limits, truncation handling, and provenance of results. Negative test cases, such as unauthorized tenant access, stale replicas, and forced timeouts, must also be executed to expose failure modes. Critically, the system's responses should preserve incomplete, stale, or unknown states rather than silently collapsing them into empty or misleading output.
