Memory Mapping - Computerphile

Modern computing relies on a hidden layer of memory management that separates logical program addresses from physical RAM. By using hierarchical page tables and hardware-level caching, CPUs ensure secure isolation between programs while providing the flexibility to map memory dynamically.
Key insight: A translation lookaside buffer (TLB) acts as a high-speed cache for address translations, because without it, the CPU would have to perform multiple slow RAM lookups just to find the correct data location for every single operation.
Can This Tiny Board Replace Your Entire HomeLab? – Zima Board 2

The ZimaBoard 2 marks a significant upgrade over its predecessor, featuring an Intel N100 processor and 2.5GbE ports that make it a surprisingly capable platform for virtualization. By running Proxmox, users can consolidate firewall, IDS/IPS, and containerized services into a compact, energy-efficient device, though the 8GB RAM ceiling remains its most notable bottleneck.
Key insight: Even with an IDS/IPS like Snort enabled and multiple virtual machines running, the ZimaBoard 2 manages to maintain near-line-speed gigabit throughput, proving that sub-compact x86 hardware is now viable for serious network security applications.
