There is no anxiety quite like powering up 2KW of basement compute after rewiring it all. Small bit of trouble with the horizontal 3090 because I misread my motherboard manual, but otherwise so far so good.. Next we see if I've built up enough cooling to hit my target TDP on those 3-slot nvlinked cards especially. The 4-slot bridges are much easier to work with but their prices went bananas and I couldn't acquire a second, so gotta get a little creative with intakes.
I like the direction that Claude Code took in visualizing context usage. As these tools are being built, I think the work now needs to focus on control over how to clean up, inspect, and profile. Renderdoc-like maybe?
