Is there actually a BLAS implementation that uses strassen? I don’t think it’s accurate that only trivial implementations use the direct o(n^3) algorithm. AFAIK high performance BLAS implementations just use highly optimized versions of it.

> 20% of all of the electricity generated in California goes to pumping water today. Hi, this is wrong. The 20% figure includes all electricity for water-related uses, not just pumping. Most of that (80-90%) is heating and other end uses

the union’s demand for a ban on automation seems quite absurd. Particularly given that they walked away from talks this summer because of an autogate system that has been in use since 2008. Surely if automated cranes is bad for employment,

winwang’s comment is correct, yours is wrong. “cuda core” refers to one lane within the SIMT/SIMD ALUs. These lanes within a SMSP don’t execute independently. The term SMSP is definitely used for nvidia’s architecture : https:/&#

1. CA already has progressive taxation. 2. The “income-graduated fixed charge” is not taxation - it is paid to a corporation, not a government entity.

In some cities in CA, the police department is understaffed (and traffic law enforcement particularly so) because 1) pension reform / reductions, 2) housing costs and general cost of living making police salaries unattractive, and 3) u

> The police do nothing. > I don’t think I’ve seen somebody “pulled over” in my city in like a decade Seems like there’s a pretty straightforward alternative here - have law enforcement enforce the law.

i suspect this could be related to the renewable production tax credit. I think maybe it works out that the US government is paying, not the solar companies. https://www.energy.gov/eere/solar/federal-solar-tax-cred

$128 per month fixed charge for having a grid tie and not using it is also expensive. This income-graduated fixed charge surely pushes the break even point towards going off grid.

I don’t think there’s been any indication that anyone is trying to figure out how to reopen Living Computers. Likely some other philanthropist would need to buy it and fund it in order for it to reopen. Paul Allen’s sister seems to have lit
