The Future of Home Fabrication: Diamond 3D Printing Arrives
A Bavarian startup claims to have solved the biggest limitation of desktop fabrication: the weakness of common 3D-printing materials. Their new device prints directly in diamond. We were given one of the first prototypes for testing. The Promise of Indestructible Fabrication For years, home 3D printing has been limited by the same basic problem: plastic.…

Memory by Round-Trip Time
When John Carmack recently mused about storing model weights not in DRAM but effectively “in flight” inside long fiber-optic loops, I felt the peculiar satisfaction of seeing a childhood thought experiment return wearing a proper engineer’s clothes. His version is, naturally, better. It has numbers, materials, bandwidth, realistic constraints, and the kind of sober physicality…
