Muffle: An Offline Android Geofencing Design That Preserves Battery Life

0
·18 views

A developer built an automatic sound manager after being embarrassed by a phone ringing during a quiet prayer session. Existing apps often relied on constant cloud syncing, data collection, or unreliable cellular connections to track location. The developer chose Google Play Services' GeofencingClient, which lets the operating system monitor geographic boundaries and wake the app only on entry or exit events. To survive device reboots, which can clear registered geofences, the design stores routines in a local Room database and re-registers them on BOOT_COMPLETED. The approach proved far more battery-efficient than the initial method of polling location every minute from a foreground service.

FBI Flash Warns AI-Driven ARTEX Attack Tools Erode Old Signs of Unsophisticated Intruders

The FBI has issued a flash alert on ARTEX-class AI attack frameworks, focusing on how language models make known intrusion techniques faster and more accessible rather than describing a new vulnerability. In a GitGuardian test of an ARTEX build without secret-scanning code, a neutrally worded prompt led the agent to locate 8 of 9 planted credentials, with the first hunting command running within 6 to 13 seconds. The report says these tools break a long-standing SOC assumption that noisy, high-volume activity indicates an unsophisticated actor, since AI agents issue rapid API calls without trying to stay quiet. In confirmed intrusions involving the AntiFox fork, hundreds of AWS calls in about 30 minutes were mostly denied, but one successful access to a production secret was hidden within that burst. Standard controls such as least privilege, IMDSv2, CloudTrail data events, OIDC, and MFA on privileged accounts still block these attacks, but analysts are advised to treat a single success among many denials as the real incident.

APScheduler Tutorial: Running Python Jobs on Interval, Cron, and One-Off Triggers

This tutorial explains how to use APScheduler, a Python library that calls functions on a schedule without relying on system cron or a separate service. It covers three trigger types, interval, cron, and one-off date, and shows how a SQLAlchemy job store in SQLite preserves jobs across restarts. The author notes that job functions must reside in an importable module, since APScheduler stores them by reference and cannot restore functions defined in the main script. The demo builds a scheduler with a metrics-collection job, a weekday summary job, and a self-removing reminder, then verifies that persistent jobs return after a restart. The tests were run with Python 3.12.3 and APScheduler 3.11.3, and the tutorial requires no API keys or external services.

Voice AI Development in 2026: A Beginner's Guide to Building Speech Apps

Voice AI has become a core part of many products, from in-car hands-free controls to conversational assistants that answer questions and draft text. Mature low-latency APIs, realistic voice cloning, and open-source models now make it easier for developers to get started. The guide outlines the main building blocks of a voice application, including speech-to-text, text-to-speech, voice cloning, backend logic, and the frontend interface. It also lists prerequisites such as Python or Node.js, service API keys, and a microphone, and shows sample code for offline transcription with Whisper and cloud speech generation with ElevenLabs.

supabase-rls-check 0.6.3 handles PostGIS tables, Expo config files, and MCP scanners

The supabase-rls-check tool released versions 0.6.1 through 0.6.3 after version 0.6.0 shipped on November 11, 2026, fixing three edge cases without adding network calls to its analyzer. Enabling Row Level Security on PostGIS's spatial_ref_sys table fails because the extension's superuser owns it, so the tool now detects extension-owned tables via pg_depend and recommends moving the extension to a separate schema instead. Baselines exported before 0.6.1 record an empty basis for these tables, so they must be re-exported once to keep CI runs consistent. For mobile teams, the scanner now also checks app.json, app.config.*, and eas.json for hardcoded service_role keys and database connection strings that could be bundled into client apps. The scanner skips common build output directories to avoid false positives.
