I can’t believe this ESP32 project is sitting in plain sight on GitHub. It’s called ESP32-BlueJammer. It uses an ESP32 with nRF24 modules to interfere with 2.4GHz communications. That includes: → Bluetooth → BLE → WiFi → RC devices → IoT gadgets → Wireless keyboards and mice The repo includes firmware files, schematics, PCB designs, and 3D case files. But there’s an important catch. The firmware source code is closed source. The developer only provides compiled firmware. And jamming radio communications is illegal in many places. The project itself warns it’s for educational and controlled testing only. Still, this is one of the wildest ESP32 projects I’ve seen on GitHub.

This GitHub repo runs a 1.1B parameter LLM on a $10 board with 256MB RAM. It’s called PicoLM. Pure C. No Python. No cloud. CPU only. Instead of loading the whole model into RAM, PicoLM memory-maps the weights from storage. That lets a 638MB TinyLlama model run with about 45MB of runtime RAM. → ~80KB inference binary → ~1 token/sec on a $10 LicheeRV Nano → ~8 tokens/sec on a Raspberry Pi 4 → GGUF models and multiple quantization formats → Linux, macOS, Windows, ARM, x86-64, and RISC-V → JSON-constrained output for tool calling It has nearly 2K GitHub stars and an MIT license. Tiny LLMs don’t need a data center anymore.

The tactic that actually works: » Filter for roles posted in the last 48 hours. » Apply the same day you find them. » Skip anything two weeks old unless you have a referral. Speed beats polish. A good application sent early wins over a perfect one sent late. The roles are there. The window is short. #RemoteWork #AIJobs #TechCareers #Hiring

One phone number. Six WhatsApp OSINT lookups. One Python CLI. It’s called WhatsApp-OSINT. The tool can check: → Profile photo → User status and basic info → WhatsApp Business verification → Linked-device information → Privacy settings → Combined OSINT results But there’s an important catch. This is not a standalone WhatsApp scraper. It’s a Python client for a third-party RapidAPI service, so you need an API key and the available data depends on that service. It requires Python 3.8+ and supports Windows 11 plus several Linux security distros. The source code is public, but the repo currently does not include a license file. Use it only for authorized security research and investigations.

Most RAG tools answer questions. This one actually builds and maintains a wiki from your files. It's called LLM Wiki. Instead of rebuilding answers from scratch, it creates a persistent knowledge base that updates as you add sources. → Imports PDFs, Office docs, EPUBs, images, media, and web pages → Builds linked Markdown pages with source traceability → Creates an interactive knowledge graph → Works as an Obsidian vault → Supports OpenAI, Anthropic, Google, Ollama, and custom providers → Connects to Claude Code and Codex through MCP → Runs on Windows, macOS, and Linux It's based on Andrej Karpathy's LLM Wiki pattern, turned into a full desktop app. 17.7K GitHub stars. GPL-3.0 licensed. Your documents stop being a pile of files and become a knowledge base that keeps itself organized.

The interesting part? Your knowledge base stops being something an agent only searches. It becomes something the agent can reason over. What changed. What’s still valid. How everything connects. And where every conclusion came from. And somehow… it’s 100% open source.

Utopia turns documents, databases, and connected sources into entities, facts, and relationships. That gives agents: → Time-aware memory → Fact-level provenance → Conflict detection → Ontology-based reasoning → Full-text + vector + graph retrieval → MCP support → Agentic RAG

This probably shouldn’t be free. An open-source knowledge system that gives AI agents memory across time. And it fixes one of RAG’s biggest weaknesses. It’s called Utopia.
