We all have to stop treating technical practices as a side quest when they are, in fact, the mission. "If the only problem were translating the cost of AI tools into end-to-end value, it would be serious enough. But something far worse is happening..." thenewstack.io/ai-co...
A chart showing two potential cost curves. The traditional one is low at first, because time is saved by not doing technical practices, then it climbs with increasing rapidity. The second path invests up front in technical practices and prevents the rapid ascent, keeping the software sustainable over the long term. This was the premise of Extreme Programming.

Both the Economist and others suggest this study demonstrates that AI can help students. So I contacted the lead researcher to figure out how many. Answer: Out of ~26,000 kids, a total of 20. And five months after starting to use AI, only four continued to spend 65 minutes on homework. Four.
Graph of student exam scores correlated to homework completion time for to groups, students using AI and those that did not. There is a slight spike for studens using AI who also maintained extensive homework completion time. As described in post, the number of students falling into this bucket was 20 out of 26,000.

I had a mini-breakthrough with Codex in terms of getting it to follow my software design and application architecture conventions (which are all documented in markdown and enforced by tools) Previously, when it violated a rule it would hack the code to make the violations go away. Inefficient.

Computer scientist Margaret Hamilton coined the term “software engineer.” She directed the Software Engineering Division at MIT’s Instrumentation Lab & led development of the on-board flight software for NASA’s Apollo Guidance Computer. She was born #OTD in 1936 & turns 90 today! #WomenInSTEM
Two side-by-side black-and-white photographs of pioneering computer scientist Margaret Hamilton (born August 17, 1936). The left panel features a mature, close-up portrait where Hamilton gazes directly at the viewer with a serene, confident, and reflective expression, framed by her long, dark, slightly silvering hair. The right panel is a famous archival photograph showing a younger Hamilton standing indoors next to a towering stack of bound paper binders containing the Apollo Guidance Computer source code, which she led the development of at MIT. She is smiling broadly and wears a striped, long-sleeved mini dress with dark Mary Jane shoes and glasses, resting her hand proudly on top of the massive column of printed code. The overall composition contrasts her youthful triumph with her enduring legacy, capturing an optimistic, intellectually rigorous mood that highlights her monumental contributions to space exploration.

It's a tacit admission that harnesses are not, in fact, reusable - that they are sensitive to changes in the ecosystem and what worked for Bill might not work for Ben. It suggests what's really needed is principles and heuristics for harness design that can adapt rapidly to each setup.
