>But will this ever be possible by an LLM?

Why not? Just train an unbelievably gigantic LLM that encodes all human knowledge. A hundred trillion parameters ought to do it.

The steps I took to find this link:

1) Look at simpleqa_eval.py. See that it loads "az://openaipublic/simple-evals/simple_qa_test_set.csv" Hmm, some weird vendored protocol.

2) I don't feel like digging through bf.BlobFile() to figure out how it downloads files and I certainly don't want to generate an API key. Cross fingers and do a Bing web search for "az://openaipublic"

3) That leads me to https://stackoverflow.com/questions/76106366/how-to-use-tikt... Ah ha, this answer has the link https://openaipublic.blob.core.windows.net/encodings/cl100k_... which automatically downloads a file.

4) Poke the relevant parts of the az:// link into this link, and a csv appears.


It's easier to find the data now, I've run some benchmarks on it. Great to see OpenAI open-sourcing datasets like this!

One of the fun things about signals theory is how the same basic concept will show up in apparently unrelated places.

Example from electrical engineering: microprocessors will have a "clock" frequency, say, 16Mhz. But when you haul a wire up to VCC and pull it back down to ground, some amount of the power will be radiated away as radio waves. If your clock is at a constant rate, then you'll have a big spike of radiated noise at 16MHz, and the FCC will be unhappy.

So modern devices cheat it by dithering around the central frequency. If you bounce from 15.9998MHz to 16.001 to 15.998 then the same amount of power will be radiated, but smeared across a bigger frequency, enough to get you lower than the regulatory threshold. Spread spectrum clock generation. https://www.analog.com/en/resources/technical-articles/clock...

If you look in your PC's BIOS settings, spread spectrum is usually an option, and you can disable it if you want your computer to be slightly noisier.


Parallax shift from the spacecraft moving along its orbit isn't measurable past 16,000 light years. The Milky Way is about 100,000 light years in diameter, so for most of the stars in our galaxy, let alone extragalactic objects, there's no effect.

For closer objects this shift is useful, as it's the only way to directly measure the distance to a object: https://en.wikipedia.org/wiki/Parallax_in_astronomy Every other method for estimating distances to astronomical objects (standard candles, redshift, etc) are based on parallax measurements.


>Presumably they lost one month of pay.

A new grade 4 hourly worker at Boeing made $19 an hour before the strike. $3,040 a month before taxes. https://www.iam751.org/docs/2024/FRONTMar24.pdf

There's a reason they went on strike. $36,480 a year doesn't go far when you have to pay Seattle area rent.


The Harbor Freight Tools store 2 exits from the plant has a sign saying that they are hiring cashiers at $22.50/hr. No exaggeration, sign is in the window, Edmonds WA location.


So what's stopping them from jumping ship to supposed greener pastures in Edmonds[1][2]?

That a IAM union machinist would even consider a voluntary career pivot to the retail antithesis of "Buy Union-Made & American-Made products" because of a window sign says a lot...no exaggeration necessary.

Unfortunately, landlords do not accept Union Pride as rent payment. We live in a society.


Benefits?


Sold out 2 contracts ago in return for a clause guaranteeing work placement in Washington state, which Boeing promptly moved to South Carolina as soon as the contract expired.


Protector by Larry Niven (1973) also features a gravity-powered telescope.


To turn trees into lumber you have to cut them down, transport them to a sawmill, cut them to size, kiln dry them, transport them to the build site, build a house out of it, etc.

Underground sequestration has no transport, milling or kiln costs. Just cut down a bunch of trees, dig a trench where the trees used to be, and bury the trunks.


Sounds like the 1980 NASA/ASEE Summer Study at the University of Santa Clara, with the proceedings edited by the prolific Robert Freitas: https://ntrs.nasa.gov/api/citations/19830007077/downloads/19...


Yes. Start at page 77: "NONTERRESTRIAL UTILIZATION OF MATERIALS: AUTOMATED SPACE MANUFACTURING FACILITY".

"The team surmises that within the next 50 years robot systems will be capable of handling a large fraction of the needs of a general-purpose SMF."

44 years later, not even close.

Google DeepMind robotics today.[1] Can put a shirt on a hanger, but not button or unbutton it.

I built a CO2 meter around a SCD30 five years ago: https://bbot.org/blog/archives/2024/05/19/pocket_co2_meter_b...

My takeaway is that it draws a lot more power than you'd expect, thanks to the incandescent light source, and unless there's quite a lot of airflow over the sensor, it'll exhibit self-heating at any poll rate under every ten minutes.


Note that NDIR sensors use a surprising amount of power, since they're based around an incandescent bulb shining light through the sample volume. A CO2 wearable will need to be recharged once a day, like a smart watch.
