I think it’s true enough to say they gave up nuclear weapons, even if they didn’t wholly own the nuclear weapons.

There was lots of discussion of these ideas in the 1990s. In those days we trained very small NNs - tens of nodes - by evolving their weights and topologies. A run could take days on a workstation of the time.

This particular paper is about co-evolving predator and prey, where the behavior of each is the ‘evaluation’ of the other.

The models don’t generate what’s right and good: they generate what people are likely to generate.

So naturally the funnest work is multi-robot systems…

I noticed on a bar TV the other day that some of the Chromecast screensaver landscape photo credits were to Peter Norvig. They were really lovely pictures.

The mean price of electricity for me is about 40c per kWh: about as high as anywhere in the US.

There are about 730 hours in a month, and a consumer machine can sustain maybe 500W, so we can spend 0.4 * 0.5 * 730 = 146 dollars on compute power per box unless we start buying special stuff.

Of course, inflation should be canceled out before evaluating the overall benefit. If you can self the goods for 7X then the fuel savings is back to 2X.

It allows you to move freight really fast at half the cost. That's a lot of things that can move around the world 100X faster than they could on the next-fastest available mode: ships and trains.

It’s better now by roughly a factor of two per passenger mile.

The nature of such large improvements is that it’s extremely hard to get such an improvement again!

This is the classic Mac behavior since the 1980s. Except now some apps are identical with their single window and will exit when that window is closed. So you no longer know what to expect. Sigh.

Why have this behavior ever? It used to be that apps took a while to start up. Switching to an open-but-no-window app was a lot faster than launching it from scratch. That’s not so important now that most apps start quickly.

Now the main advantage is that you can use keyboard shortcuts to make a new window in open apps (CMD-tab, CMD-n gets a new window in the previously used open app, for example)

marcelroed is modest, this speedup is not. Good work.

Which is 30% less than the original iPhone accounting for inflation.

Given inflation and the increased utility of the smartphone, we're almost certainly at the lowest cost per hour of use ever for most people.

Since the LLM is now designed to run in a harness, it’s really not even wrong any more.
