mrfusion··on A few concrete arguments for e-bikes
Do we think these will come down in price in the next few years? I $500 want one, but not $3000.
mrfusion··on Marriage Markets (and Muscularity)
I don’t understand what you’re saying. What’s wrong with eudaimonia?
mrfusion··on Show HN: I built a website to find nearby cafes to work remotely from
Could you make each purchase include an hour of wifi? It wouldn’t be too hard to set up and I don’t think people would mind.

Or after an hour keep providing wifi but put up a guilt screen explaining that you have costs etc.

mrfusion··on Results from first US trial of genetically modified mosquitoes
Not at all.

I’m saddened that a jurrasic park comparison shuts down all debate without considering the merits or risks.

mrfusion··on Double ridge formation over shallow water sills on Jupiter’s moon Europa
Better to take that risk and learn what’s there than to never know.
mrfusion··on Results from first US trial of genetically modified mosquitoes
Nothing has held back science and progress more than that one quote in that one movie. Pretty amazing if you think about it.
mrfusion··on How DALL-E 2 Works
Maybe an artist can make huge images or whole catalogs of images with technology like this.

Maybe more people can be game developers with access to free original artwork at their fingertips.

I don’t see it as replacing artists, I see it as amplifying artists.

mrfusion··on Ask HN: Why is Substack so popular?
I love sun stack but I really think they need a way to pool subscriptions or lower the cost.

I’m not going to spend $100/month to follow my ten favorite bloggers.

mrfusion··on Lowering sodium intake doesn’t help heart patients
I have a theory that a large percentage of food cravings and idle snacking are due to being salt deficient and seeking out salty foods.

Perhaps part of the obesity epidemic is due to the vilification of salt?

mrfusion··on 3M tape with anisotropic z-axis electrical conductivity
I don’t quite get how that’s useful.
mrfusion··on No one knows why the most used spacecraft propulsion system works
Could Hall effect be used to accelerate ions fast enough to fuse? Could this be another Avenue to achieving break even fusion?

Also Could nitrogen be a passable Hall effect thruster fuel?

I envision refilling propellant by the craft dipping into the upper atmosphere and scooping up some air.

mrfusion··on No one knows why the most used spacecraft propulsion system works
Have we given up on the vasmir thrusters? Did Hall effect win out? Why is that?
mrfusion··on No one knows why the most used spacecraft propulsion system works
Thanks! Could super conductors help increase efficiency or density? Why or why not?

Could this be a viable space to launch a start up? With launch costs coming down there could be a lot of demand for more efficient thrusters.

mrfusion··on No one knows why the most used spacecraft propulsion system works
AMA? How much can these thrusters be scaled up? Or does it make more sense to stick more smaller ones on a craft if we need more thrust?

Bonus question: how would you design a planet scale thruster? (Asking for a friend)

mrfusion··on No one knows why the most used spacecraft propulsion system works
Say why can’t we make a small scale circular particle accelerators and push ions out with that? Would that be more or less efficient?
mrfusion··on Unreal vs. Unity Opinion
Is anyone working on making Python work with it? That would be amazing.
mrfusion··on Unreal vs. Unity Opinion
Is Godot out of the question? Is it mostly a performance thing?
mrfusion··on Stabilization of gamma sulfur enables 4000 cycle Li-S batteries [pdf]
The problem is a 300 mile range isn’t a true 300 miles. There’s losses for temperature, running the heater, battery reserve, etc.

I see 300 possibly being sufficient but I’d want the advertised range to be 400 to make sure I reliably get that.

mrfusion··on New on Reddit: Comment search, improved search results relevance, search design
I thought you could always search comments. What am I missing?
mrfusion··on Elon Musk makes $43B unsolicited bid to take Twitter private
> I think about Twitter occasionally and I'm always amazed that the company has thousands of employees.

Once a company gets big enough, 95% of an employees job is navigating the bureaucracy. So the head count goes way up.

mrfusion··on Elon Musk makes $43B unsolicited bid to take Twitter private
> We've never had a situation where fake news can and does spread the way it does today, where authorities are being undermined like this and casually dismissed by people with no knowledge of the respective fields, etc.

If authorities were never “undermined” you would still be drinking cocaine, giving your kids cough syrup laced with heroin, spraying people with DDT, and also smoking the cigarette brand your doctor recommended.

mrfusion··on Elon Musk makes $43B unsolicited bid to take Twitter private
> ..the peculiar evil of silencing the expression of an opinion is that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth; if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth produced by its collision with error.

mrfusion··on A new heat engine with no moving parts is as efficient as a steam turbine
We could drastically shrink coal, and nuclear power plants if we can do away with the steam turbine portion.
mrfusion··on K-Nearest Neighbors
I could be wrong. If you give it bad data then it could still overfit.

https://datacadamia.com/data_mining/overfitting

But if all your data is good There’s no training step per se. And it just keeps improving with more data.

mrfusion··on K-Nearest Neighbors
I believe it also makes overtraining impossible which is pretty strange for a learning algorithm.
mrfusion··on Iron Cycle based energy storage and generation
You could wire them up in serial to increase the voltage.
mrfusion··on Consumer prices rose 8.5% in March – highest since 1981
A local restaurant just got rid of their paper menus because it was too expensive to reprint every time they wanted to raise prices …
mrfusion··on Interstellar object exploded over Earth in 2014, declassified govmt data reveal
Why are we assuming it couldnt course correct?
mrfusion··on DeepMind’s New Language Model, Chinchilla
Does this imply we will run out of data to keep up with larger model sizes?

Is there much more data out there than what they’re already using?

mrfusion··on Tenacity and Life Lessons through the 33% rule
Cool idea. Devs need something like this for sure.
