sadhorse··on Abundant Intelligence
Nobody will be afraid to use AI.
sadhorse··on Strain gauge made out of PCB
Use vibration to measure small masses. Measuring natural frequency can be very accurate and sensitive.
sadhorse··on Berkeley Humanoid Lite – Open-source robot
What kind of vision peocessing are you envisioning?
sadhorse··on Electric Propulsion's Dirty Secret: Why Lithium Can't Fly (Or Float) Profitably
It is pollution and it harms people. So in order to do things that are good we must harm others first (or after)?
sadhorse··on Electric Propulsion's Dirty Secret: Why Lithium Can't Fly (Or Float) Profitably
How dare you stand in the way of regular people burning hundreds of kilograms of fossil fuel in order to spend a couple days at the beach? /s
sadhorse··on The race is on to build the most complex machine
Not if we follow strict operating procedures, Gordon.
sadhorse··on How can this 6 axis robot have a static accuracy of 0.05 mm? (2021) [video]
Legit question: if I replicate a patent for a personal non profit use, is this infringement? Perhaps it is because I'm benefiting from the intelectual property.

Depends on how much power you need (speed times force, acceleration and deceleration...) and how much stiffness you need (can't bend?).

Also depends on how much travel you need. It is easier to get 50 micron accuracy over a total length of 100 micron compared to a total length of 1 meter.

sadhorse··on Emergence of ferromagnetism at onset Kondo breakdown in moiré bilayer lattices
Is this related to lasers behaving as as a body with negative temperature when they manage to heat something to a hotter temperature by radiation?
sadhorse··on Microwaves: A Haven for Bacterial Diversity
Microwave heating is not a fourth form of heat transfer as it name implies: microwave radiation. Yes, the heat is not being radiated by a thermal source of microwaves, but it is radiation being absorbed. Hence radiation is the mechanism.

Rotational momentum is also heat as it is kinect energy related to movement, linear or not.

sadhorse··on Secure Boot is broken on 200 models from 5 big device makers
If you dig deep enough all our land is on a floating basis.
sadhorse··on United States discloses nuclear warhead numbers; restores nuclear transparency
Enriching uranium is more expensive than making plutonium by a long shot. Modern nukes are two point implosion, not really fiddly. And when was the last criticality incident related to phase transition? Can't remember one.
sadhorse··on Multisatellite data depicts a record-breaking methane leak from a well blowout
How so? Huge flooding in Brazil this year, they are not recovering any time soon. Poor countries lack the resources that rich countries literally burn for their luxury.
sadhorse··on First anode-free sodium solid-state battery
Because the market is made up of selfish human beings. First they don't care for long term environmental consequences. If that is not enough, then they use fossil because their enemies are using, and not using it means getting destroyed today.
sadhorse··on AI's $600B Question
I recall Marvin Minsky saying that 1 GigaFlops would suffice for doing most of what humans do. Current AI is addiction to more data, more compute but no smarts. At least they gave us cheap compute, soon the right people will figure out how to produce real AI, not this travesty.
sadhorse··on Intel is trucking a 916k-pound 'Super Load' across Ohio to its new fab
Sadly you can't get a glimpse on the immense effort we put into destroying our society. But the nunbers are available if you are curious enough.
sadhorse··on Suddenly There Aren't Enough Babies. The Whole World Is Alarmed
Psychopathy is also on a normal distribution... this "big numbers" argument is very weak. We all know what the masses like to do with the environment.
sadhorse··on Supervision: Reusable Computer Vision
How are these people arranged in the image? It is doable with good models and some sanity checks, comparing hands per square meter and heads per square meter.
sadhorse··on Supervision: Reusable Computer Vision
YOLOA model has knowledge for dozens of objects. At every frame it is computing lots of parameters not related to your case. This is very wasteful and the main reason you can't achieve your performance goals.
sadhorse··on How Chain-of-Thought Reasoning Helps Neural Networks Compute
Does every token requires a full model computation?
sadhorse··on Why it's so challenging to land upright on the moon
Humans did it manually in the 60's. How hard can it be to do it with computers and radar? I don't want to sound like that guy but... how hard can it be?

Edit: My point being: spacex is already doing it on earth, dealing with stronger gravity and air non linearity.

sadhorse··on John Deere Announces Strategic Partnership with SpaceX
It can also be done locally with a fixed base station.
sadhorse··on Google TPU v5p beats Nvidia H100
More compute can't save you from dumb methods. Memorizing the whole of human text while being fooled by a prompt crafted by a 14 year old doesn't mean its intelligent.
sadhorse··on ALOHA robot learns from humans to cook, clean, do laundry
A reminder that so called engineers will bleed you dry before anything. As with many robotics projects, the people hired excel in one thing:doing what they already know. That is why you and I never see new robots.
sadhorse··on Google is apparently struggling to contain an ongoing spam attack
Also recommend. Others liked. Recommend for you. Shorts section.

Search is unusable.

sadhorse··on Google is apparently struggling to contain an ongoing spam attack
Most ads I see on YouTube are very dubious and poorly made. A reasonable ammount are plain fraud. It is very frustrating going to "ad center" and reading about how the advertiser did not verify his identity.
sadhorse··on After 151 years, Popular Science will no longer offer a magazine
VC tend to invest in things going the opposite way.
sadhorse··on Men less likely than women to share negative information, says study
"Walled garden academic peer review" is not above "centuries of years of group knowledge peer review".
sadhorse··on Ripple CEO says SEC has lost sight of mission to protect investors
You know what I'm tired of? Not being able to investments because I'm not a "accredited investor", therefore I must be dumb or something.
sadhorse··on As I retire, my goal now is to release 40+ years of source code
I agree with that, and I am comfortable with the prospect of others not putting themselves first, therefore opening up the possibility of them putting my interests first.
