Common MPO Cabling Mistakes in 400 G and 800 G AI Data Centers And How to Avoid Them

4+ hour, 3+ min ago  (666+ words) As AI data centers, HPC clusters, and hyperscale cloud infrastructures rapidly adopt 400 G and 800 G Ethernet and Infini Band networks, MPO/MTP cabling has become the foundation of high-speed parallel optical interconnects. While optical transceivers and switches often receive the…...

Banana Pi M7 vs Pi 5: The $80 Board That Outperforms for Wi-Fi Auditing

5+ hour, 12+ min ago  (1172+ words) Spoiler first: the Banana Pi M7 is not actually $80. Street price in 2026 is $165 on Ali Express, $210 at Ameridroid if you want US shipping and a warranty that answers emails. The Raspberry Pi 5 8 GB really is $80. So why is everyone on my…...
