This note explains how to compress videos using FFmpeg with HEVC (H.265) and H.264 (AVC), focusing on broad compatibility across devices — PCs, TVs, ARM devices, mobile, and browsers.

This script benchmarks a TrueNAS ZFS pool, including sequential and random I/O tests, and logs results for analysis.

This guide covers:

• Checking HBA firmware & mode
• Updating firmware (IT mode)
• Enabling PCI passthrough in Proxmox
• Migrating HDDs from motherboard SATA to HBA
• Setting up VFIO bindings
• Verifying PCIe lanes per chip
• Listing disks per HBA chip

Before configuring Proxmox, enable the following in your system BIOS/UEFI:

• Intel CPUs:
  • Intel Virtualization Technology (VT-x)
  • Intel VT-d (Directed I/O)

• Docker caches layers based on commands in the Dockerfile.
• To take advantage of caching:
  • Copy dependency files (pyproject.toml, uv.lock, etc.) before source code.
  • Run dependency installation (uv sync, pip install) before copying the app code.
• Cache is reused if the files/commands in a layer haven't changed.

uv is a fast and modern Python package, environment, and project manager that can:

• Install and manage Python versions (like pyenv)
• Handle dependencies and virtual environments (like Poetry)
• Run CLI tools without global installs (like pipx)

1. Open Proxmox Web Interface → Storage (e.g., local, local-lvm).
2. Select CT Templates.
3. Click Templates (top-right).
4. Choose a template (Debian, Ubuntu, Alpine, etc.) → Download.

sudo apt install tmux
tmux

• Starts a new tmux session.
• Even if SSH disconnects, the session keeps running in the background.
