If you don't believe in aggregating different measures of intelligence, you can simply not aggregate the different categories of questions in IQ tests. For example, you can separately average just the shape rotation or language questio

200-400V DC distribution systems are dangerous, both for electrocution and fire. Though maybe modern GFCI and arc detection breakers could make them adequately safe. Could someone who knows the state of the art comment?

The bias is really towards recency, because LLMs are mostly trained on text scraped from the internet. If you incorporated older content, the bias would be much less liberal. It'd be interesting to train one on only pre-1950 content.

The question is whether the round-trip inefficiency of storing energy is greater than the cost of having energy-consuming equipment that sits idle when the sun isn't shining and gets stopped and started frequently. For example, aluminu

Nobody is claiming it's the solution to everything. The lesson from history (and not obvious from first principles) is that it's hard to predict what technology will be good for. You have to invent it first, and let people try to

max_align_t is only the max for scalar types, typically 8 or 16 bytes. But often math-intensive code wants 16 or 32 byte alignment for float arrays, to enable SIMD operations.

I think it'd be cooler if the motors turned slower, slow enough to see, and had more lines on the disk to get the same sound pitch. Optical encoders for motor position sensing often have 1000 lines, so they could spin around 1 rev&#x2F

Ah, I thought you meant the speed of parsing the payload didn't matter (scanf performance was also discussed). Yes, parsing the format string in printf or scanf isn't a big deal.

You're almost always better off buying individual stocks yourself. You can optimize your return in various ways, like tax loss harvesting to offset capital gains from other sources like stock options. There are cheap robo-advisors that

That was once true, but not on most modern systems with SSDs. Cheap NVMe SSDs can sustain over 1 GB/s, which only a highly optimized SIMD parsing library can exceed.

I was hoping for the Undersea Republic of Atlantis. Which will probably surface some day.

The hard thing with lubrication is sealing it so it doesn’t leak. Considering the pinion gear and shaft moves in 2 axes relative to the housing, that could be tough.

Unsprung mass sucks. You don’t notice on smooth surfaces, but if you are cornering on a rough surface the wheel ends up losing contact with the ground after each bump. It’s extra-dangerous when its the rear wheels because the car can spin o

This wouldn't have worked for ICE cars, because in order to have a reasonable range of up-and-down movement the gear ratio needs to be quite high (ie, the pinion gear has to be much smaller than the ring gear). It's 6.2:1 in the a

Are you asking if most AI startup founders decided to start their companies (and dedicate years of their life) in order to "ease the recession hit"? I can assure you that's not a frequent motivation to start any kind of start

Global commercial flight traffic averages around 100k flights per day. I don't know what fraction is within the radar range of a big ship in a busy area, but maybe 10k? So it's not trivial to avoid reuse within a day while still h

Wolves and wild dogs are large, by modern dog standards, and don't live very long. Selective breeding created the smaller breeds, which live longer. So maybe you want to ban wild animals instead.

On modern systems, crashes happen maybe once a year, while outright disk failures or undetected memory errors corrupting disk blocks happen maybe every 100 years. So if the chance of corruption from a crash is 1%, the overall risks are comp

We should praise leaders for doing what the people want instead of what they might want themselves.

It takes practice. After meeting 100 CEOs and watching their companies evolve for 5 years, most people can be OK at it. Some people (famously Jessica Livingston) are much better than average. But few people have the chance to practice that

FORTRAN77 only allowed 5-digit numbers as labels. So people developed habits for numbering loops & ifs. Programs definitely lost readability if you renumbered them. The labels were in fact numbers, not just numeric strings, since there

You’re right. While a pure tone can only have higher harmonics when distorted, multiple tones can produce the difference frequency. And noise has every tone.

When you generate blue noise by shaping in the frequency domain and transforming, the samples are gaussian distributed, not uniform, as the author mentions. I wonder if you can transform to a uniform distribution by sorting the samples, cho

It's one way that people try to be vague for privacy reasons. But feel free to use a more specific term if you're comfortable releasing that bit of information.

Killing trees increases the market price of olive oil, so it's to the crime syndicate's advantage. So it's just hateful, not stupid.

What's the goal behind making them exchangeable? The usual plan is to recalculate embeddings whenever the model changes, or when moving between systems. You'll almost certain want to update the model over time, as the input distri
