Comment Split space bar is a poor start to thumb clusters (Score 1) 57

Split space bar is better than a standard one but it is only a poor start to separated thumb clusters which provide somewhere from 6 to 9 easily reachable keys per thumb.

Check out e.g. K80CS layout. That is a custom build and there are many similar (and from my point of view slightly worse) custom keyboards in the community. People mostly do not want to build their own keyboard. They can get a usable commercial alternative which is not too bad. There are more of them, e.g. Kinesis Advantage 360.

A split keyboard with thumb clusters is the most important feature. If it is contoured then even better.

It is dispatch-able if you overbuild cooling to 100% of thermal power.

Most reactors build cooling only to about 50% of thermal power. They do it since they assume they can always sell at least 50% of electrical power to grid. They assume this since they can lower price to zero (and out compete others) when needed. They can afford this since nuclear fuel is only about 2% of the overall costs. So there is no serious problem to waste fuel into heating the environment around the plant ... provided that they do not cool in a local river only which they cannot overheat without killing the river life.
Look at nuclear electricity production in France around summer solstice. You will see that it fluctuates quite a lot.

They did from about 9.6% in 2004 to about 25.2% in 2024. This if for European Union only. Eurostat data. I do not know what was the renewable percentage in 1990. Definitely lower than in 2004.

Of course, it does not help them much since renewable sources are not dispatch-able. The result is that electricity prices are about 10 times lower at noon when compared to early morning or late evening. Sometimes they may be negative at noon. This is true for spring/summer. The price difference is not so big in autumn/winter when solar does not work that well and fossil fuels must work more ... i.e. prices are high even at noon.

I guess his point is that LLMs only do rote memorization with so little of proper reasoning steps that we may as well consider them incapable of understanding.

It is also very hard to distinguish between an LLM to simply spitting out a learned answer instead of doing some reasoning from a more generic model to come to the answer. If the LLM was taught an answer to your question then it can just provide the learned text without any (deeper) understanding of it. It may have only done some simple substitutions to the memorized data to give output tailored to your specific question. This is a big deal from my point of view. We do not know whether the model inside LLM is simple enough compared to the model humans have (i.e. Kolmogorov complexity of the model is not too much bigger in LLM than in a human).

It has been shown that LLMs can reason to at least a very limited level. It is not only memorization of the training data. They can do at least one reasoning step (e.g. a simple substitution rule or a simple modus ponens rule ... here and there ... mostly correct :-D ). But it is hard for users to estimate how much of some LLM response is rote memorization and how much of it is a reasoned response from a smaller more generic model. We do not know whether about the same question as we are asking was in the training data.

AI models don't "understand" anything.

A popular sentiment, it seems. Can you please explain what you mean by the word in scare-quotes? What is the intended point? I really can't understand what you mean, and I'm human.

Understanding comes from learning (symbolic) models of reality in our brains and an ability to reason about those models to an arbitrary degree. The reasoning allows us to validate our internal models, update them with newer facts and to derive proper consequences (i.e predict the likely future based on them). That is the whole point of intelligence. Predict the future so that we can optimize our current behavior to do better in the future (i.e. increase our chance of survival into the future).

Additional data collection and the reasoning about the future happens in steps. Each step must be performed correctly to reach the right conclusion. LLM AI can properly execute smaller number of steps than skilled humans. LLMs reason only within their context window size. LLMs discard any data that overflows this context window. LLMs more likely ignore the data more deeper (more ancient) in their context window. The more this context window is filled the more likely they make mistake in each particular step. The result is that LLMs tend to go awry sooner than skilled humans over time.

Already, at Intel's 1.8nm, we're looking at ~16 atoms.

The process numbers do not mean feature size for a long time already. They are more like: What feature size the old process would have if we achieved the same part count per unit of area? Lets call this number the new "feature size".

Kiki is a bit more loud at higher frequencies than buba.
Spiky shapes generate higher frequencies than rounded ones.
If the chicks were exposed to any sound and visual info before the test then one would expect this result. They may have learned the correlation between higher frequencies and spiky shapes even during the test. I think there is a tiny chance the correlation may be genetically "pre-wired" in brain.

They produce more tire particles since they are heavier and can accelerate more aggressively.

They also use slower-wearing tires, and wear their tires less to accelerate (hence why they can use lower-wearing tires) on account of their advanced traction and throttle control.

Well, one can use slower wearing tires on ICEs too. That is a feature of tires and not cars. It is easy to replace tires. There may be something considerable in your argument that they have better traction control (which is possibly harder to do with ICEs, maybe only not as common with ICEs). But does this alone compensate for higher weight and higher accelerations of EVs? If so, do you have some good links explaining this?

allowing for an equivalent-mass EV to perform better on a much slower-wearing tire

EVs are typically 30% heavier (not equivalent mass). They produce more tire particles since they are heavier and can accelerate more aggressively. They produce less brake pad/disc particles since they use regenerative braking.
