I joined Terra Populus in 2012 as a senior engineer and inherited the lead role after the original leadership left in 2013. We received about $8 million from NSF to harmonize population, environmental, and land-use data for the research community. Output free; the work that produced it was not. That experience is why I respect the engineering layer in commercial alt-data services like Quiver Quantitative even as I cancel my subscription.
I wrote an open-source simulated-annealing PCB placer to benchmark against Quilter, a commercial placement service. On a dense 161-net Arduino Giga shield, Quilter routed 99.4% of the board; my placer plateaued at 93.8%. Here is the full comparison, the numbers, and the specific class of signals that pyplacer couldn't get routed.
Kyegomez published OpenMythos as a speculative, open-source reconstruction of Claude Mythos. I ran the 1B variant on a Strix Halo (Radeon 8060S, ROCm) to test what an open reconstruction of a frontier model can and cannot teach you. The architecture's internal claims check out: rho(A) at init is exactly e^-1, the spectral-radius stability constraint prevents the failure mode it's designed to prevent, and hidden states blow up exactly as the LTI analysis predicts. What it does not teach you: anything about Claude Mythos.
Part three of a series on designing an Arduino Giga R1 level-shifter shield with Claude Code and open-source EDA tools. Covers the v0.4 respin: what Claude Code actually helped with, what it didn't, and what six hours of Freerouting clearance debugging revealed about the limits of LLM-assisted hardware design.
A subtle pin numbering convention mismatch in a Python-generated PCB turned a working design into a board where every signal on the dual-row headers was at the wrong physical position. How we found it, why it passed every automated check, and what the fix looks like.
A Z80 DIP-40 weighs 5.7 grams. Run Zork on it, or run Zork in a browser emulator. The bytes execute the same way. One of these is a thing in Heidegger's specific sense. The other isn't. This essay works out what's different, why the home lab and retro computing communities feel it, and why cloud abstraction is designed to erase the gathering.
