The Download: how AI could improve construction site safety, and our Roundtables conversation with Karen Hao

technologyreview.com Rhiannon Williams 2026-02-11 11:10:00

More than 1,000 construction workers die on the job each year in the US, making it the most dangerous industry for fatal slips, trips, and falls. A new AI tool called Safety AI could help to change that. It analyzes the progress made on a construction site each day, and flags conditions that violate Occupational Safety and Health Administration rules, with what its creator Philip Lorenzo claims is 95% accuracy. Lorenzo says Safety AI is the first one of multiple emerging AI construction sa

Performance Debugging with LLVM-mca: Simulating the CPU

Some time ago I had a performance problem that wasn’t easy to explain by just looking at the code, since the version I expected to be faster was actually slower. Since the problem is simple yet illustrative, I am using it as a showcase on how to debug performance issues using llvm-mca.

PJ5 TTL CPU

news.ycombinator.com Unknown 2026-02-19 17:05:58

Well, we did it… we cracked 4MIPS on our TTL CPU. I have to admit I’m both relieved and surprised. The key parts to achieving this was to decrease the latency for the instruction decode and also the flag register writing. The time to decode an instruction, perform a bit of math and then write to the flags was at around 270nS. With the changes we made, the instruction decode had a radical reworking and the flag writing had some big changes as well, means we go this down to under 200nS. Which m
