Experimenting with local LLMs on macOS

Running **open-weight LLMs locally on macOS**? This post breaks it down clean. It compares **llama.cpp**—great for tweaking things—to **LM Studio**, which trades control for simplicity. Covers what fits in memory, which quantized models to grab (hint: 4-bit GGUF), and what’s coming down the pipe: *..

How In-Memory Caching Works in Redis

Redis isn’t just a cache anymore. Sure, it still owns the in-memory speed game—with **key expiration**, **data persistence**, and **horizontal scaling** via **replication** and **clustering**. But if you're only using it to stash a few keys, you're missing the point. This thing handles **streams**,..
