This is the fastest Arm desktop in the world, yes, even faster than the M2 Ultra Mac Pro. And today, I made it even faster. I upgraded everything: Faster RAM, 128 core CPU, 40 series GPU, I did it all, and we'll see how much we can obliterate the M2 Mac Pro. 128 cores—that's five times more cores, I'm also going to…

NVMe SSD boot with the Raspberry Pi 5
In my video about the Raspberry Pi 5, I mentioned the new external PCIe port makes it possible to boot the standard Pi 5 model B directly off NVMe storage—an option which is much faster and more reliable than standard microSD storage (even with industrial-rated cards!). Enabling NVMe boot is pretty easy, you add a…
