Relatively few industry keynotes have Nobel Prize Winner presenter. Hassabis was promoting the Gemini Scientists Assistant.

RPN interpreters require very little core memory. So they were popular with computers where core memory was under ten kilobytes.

But its horrible for software engineering with multiple programmers and large codebases. Lacks structures, interfaces, modules, data abstraction that you expect in a modern language. We called it the "Chinese food" of coding- ten minutes later you had nomidea what you just coded.

Frame buffer memory was still incredibly expensive in 1980. Our labs 512 x 512 x 8bit table lookup color buffer cost $30,000 in 1980. Mac's 512 x 384 x 8bit buffer in 1984 had to fit the Macs $2500 price. The Xerox Alto was earlier than these two devices and would have cost even more if it had a full frame buffer.

My state has flat tax rate of federal taxable income (after deductions). Most years its free online filing and typing 5 or 6 numbers. Takes five minutes. The tax softwares dont like that because they get half their income from state filings.

I dislike that I dont get the long term capital gains discount like on federal.

Astrophysicists use a similar algorithm to build giant particle evolution models of galaxies and cosmology. It would be computationally prohibitive to compute the gravitational or electromagnetic force for every combinatorial pair of particles. So the mass/force are averaged in a hierarchical set of subcube centroids.

More recently it would be self-professed gays. A frat might feel the gay might come on to them, or brand the entire frat as gay. The other similarity is there is at least one predominantly gay frat.

These days there is so much gay publicity, that many young people would no longer think this is an issue, as it no is with Black and Jewish members.

The physical human brain has 86 billion neurons with up to 10,000 connections each. However they are somewhat structured (e.g. the seven layers of the cerebral cortex segregated into vertical silos a few hundred cells wide) reducing the arbitrariness of connections. So say the connectome has 100 trillion parameters.

The brain also has a bunch of other cells that dont appear to encode information. They may supply structural scaffolding and chemicals to mediate neuron function.

I suggest the human-mammal mind readily adapts to new sense modes. Driving a car or riding a bicycle feels like an extension of the body after you mastered it. A grid of bump actuators agains the skin or tongue is perceived as an image after one uses it for a while. So I reject the idea that bat consciousness is special. We'd perceive sound images had we had high frequency ears and emitters.

Deposit banks were banned from crossing state lines and investing in equities markets after the Great Depression. These limitations were removed in the 1990s.

Round 2 of the 2023 bank crises might be commercial real estate loans like the 1980s crises. Some downtowns are still 40% vacant. This more a consequence of covid than bad bank behavior.

The founder of WeWork was talking about creating this kind of housing- private bedrooms (and mainly bathrooms too), kitchen, living rooms shared. A monthly fee for frequent cleaning of public spaces, because voluntary efforts not so successful.

An issue would be maintaining the age segregation of a college. Single adults of all ages may want to move in.

The pedophile scare alternates between the absurd and underestimated.

On the absurd side are:

- Satanic preschools

- Pizzagate

- most recently, drag queen demonization

On the underestimated side:

- unending Catholic priest incidents, most recently Baltimore. Non-Catholic pastors too

- Boy Scout leaders

- sports doctors

Heavyside's vector notation compressed Maxwell's twenty-some component equations into four. Thats elegant for teaching and teeshirts. However when I want to compute them on a computer grid, I use something closer to Maxwell's original equations.
