llama.cpp + CUDA 13.2 on Ubuntu 24.04 with GTX 1650 Ti - setup notes and learnings for 4GB VRAM

llama.cpp + CUDA Setup — What I Learned

System: Ubuntu 24.04, GTX 1650 Ti (4GB VRAM)

Hardware Limits

  • 4GB VRAM fits Llama 3.2 3B (Q4_K_M) fully on GPU with 4K context
  • 8K context = partial CPU offload (slower), 16K+ = mostly CPU
  • TinyLlama 1.1B runs easily with full offload
  • No tensor cores on GTX 1650 Ti -- warning is cosmetic
  • 7B models don't fit at Q4 (4.5 GB), Q2 is degraded quality

How domains, DNS, and hosting work - simple explanation with ASCII

How Domains, DNS & Hosting Work

The Problem

Computers talk using IP addresses like 76.76.21.21.
Humans remember names like google.com better.

DNS (Domain Name System) is the phonebook of the internet — it translates names → IPs.

Generic bash service runner — start/stop/restart/status for frontend + backend projects with PID tracking, port killing, and health polling

Generic Bash Service Runner

A reusable bash script template for managing multi-service projects (frontend + backend) with a single CLI.

Features

  • Start / stop / restart / status for both backend and frontend
  • PID file tracking via /tmp/ — survive terminal close
  • Intelligent port killing — tries lsof, fuser, then ss
  • Health-check polling — waits for actual readiness before returning
