tejtm··on The recurring dream of replacing developers
Pre industrial revolution something like 80+ percent of the population was involved in agriculture. I question the assertion of more farmers now especially since an ever growing percentage of farms are not even owned by corporeal entities never mind actual farmers.

ooohhh I think I missed the intent of the statement... well done!

tejtm··on The tiniest yet real telescope I've built
This coming year ... if the crik don't rise (as it does with some regularity). Some of you may be able to take a picture of yourself with one of Ril ter Horst lenses as it will be launched in a 2U cubesat named OreSat1 by Oregon's Portland State University undergrads.

pictures would be captured by hand held groundstations

Your correction to my perception of what you intended 0.4 inches to represent is accepted.
tejtm··on Root System Drawings
decimal place issues... I hope.

there are ten mm in a cm

456cm == 4560mm

there are 24.5 mm per inch (it is the law).

4550mm / 25.4 = 179.527 inches

or about 14.9 feet

which is about 5 yards

which is 20% of a 'murican football field if that helps

tejtm··on Why the push for Agentic when models can barely follow a simple instruction?
great job digging up a reference! you must be a bot! :)

I read it in a book on AI, unfortunately that aisle in my library is inaccessible due to piles of obsolete crap (I wish I were kidding).

But hope springs eternal and if I get back and find it I will return here and add its deets to see if it was published before or after the SI article.

got to help future agents from going astray ...

tejtm··on Why the push for Agentic when models can barely follow a simple instruction?
Nigh thirty years ago when dabbling in AI I read a quote I will paraphrase as:

"when you hear 'intelligent agent'; think 'trainable ant'"

tejtm··on Eliminating contrails from flying could be cheap
Every wavelength of the electromagnetic spectrum that is not actively being generated, is decaying. At minimum the expanding universe saps frequency.

More directly,radiation (light,photons) is absorbed and re-emmited by matter but the re-emitted energy is always at a lower frequency.

This absorbed & re-emitted longer wavelength radiation is what can become trapped.

tejtm··on One to two Starlink satellites are falling back to Earth each day
This has already been addressed as LEO is not geostationary but to point as to why. Consider the earths equator rotates at a particular velocity so there is a particular orbital radius where the two cancel and NO energy is needed to fall around the equator at the same rate the equator is moving. That is a geostationary orbit.

LEO maxes out ~ 1,200 miles radius, geostationary is at little over over 22,000 miles radius.

tejtm··on One to two Starlink satellites are falling back to Earth each day
Automatic EOL (end of life) deorbiting is a feature not a bug.

I will again note that if Saber Tooth tigers had put things in the orbits we have, it would still be our problem.

tejtm··on Astronomers discover 3I/ATLAS – Third interstellar object to visit Solar System
A Molecular clock would be gravity in your model, when ever you called stop all your marbles would have experienced the same amount of gravitational force. That is the intent of "experienced the same amount of evolution" and similar.

Where I see the model flounder is; the hill provides the fitness context. You implied distance "means" more evolved, but for life it is all about making it to the next round, in your marble game how many of those furthest marbles will ever be found for the next round?

With life big changes are dangerous, you may find yourself improved out of options.

tejtm··on Astronomers discover 3I/ATLAS – Third interstellar object to visit Solar System
frame of reference matters, from the center of the sun or galactic core they all most certainly moved the same distance in the same amount of time and it was much further than the hill was tall.
tejtm··on Copper is Faster than Fiber (2017) [pdf]
Pedantically, light is still EM.

But I think I understand what you mean.

The shape of individual EM waveforms is no longer relevant instead there are just buckets of got some or not.
