barelyauser··on Experiencing scientific revolutions: the 1660s and the 2020s
Aging is the breakdown of your biological functions. We can measure it therefore we can fix it. Be it with genetic engineering or with a external treatment.
barelyauser··on How real is America’s chipmaking renaissance?
They profited offshoring now they will charge you to bring it back so they can profit some more. The wheel will continue to spin and nothing will come from it. Just enjoy the ride.
barelyauser··on Successful room temperature ambient-pressure magnetic levitation of LK-99
According to this, breakeven can already be achieved. Rather funny how this is a highly advanced research topic and a mistake like that could take place (if real). https://en.wikipedia.org/wiki/Muon-catalyzed_fusion#Alternat...
barelyauser··on The Blue Flash: A careless slip led to a fatal accident in the Manhattan Project
I think a preventable one. Consider the Air France 447 accident. It came to be due to various conditions. But I remember a lot of headlines about "if only the pilots had not done anything, the plane would have cleared the weather and keep on flying". I think putting the whole thing into a "single slip" enhances the drama.
barelyauser··on The Blue Flash: A careless slip led to a fatal accident in the Manhattan Project
But it really does sell the grand tragedy that it is. Thoughtful and comprehensive analysis does not sell well.
barelyauser··on LK-99: The live online race for a room-temperature superconductor
Yes, but the original post means "spending" as "making good use of if" or "putting it to a productive end". People betting money has very little effect on the world. But consider the case where I pay you to be idle for an hour. I destroyed 1 hour of your labor, you got paid but we are not in any shape or form richer because of it. Or consider people attending a charity event. They pay to attend, then spent 1 hour having fun. After the event, they will have to in fact labor to provide the charity when the fund raising event starts to spent its money. There is no cheating nature.
barelyauser··on ASML EUV lithography machine could keep Moore’s Law on track
You may be able to surpass it in resolution but you can't surpass it in terms of throughput.
barelyauser··on Samsung sees 95% drop in profits for a second consecutive quarter
It depends. Do regular profits "trickle down" or are they stored away in foreign countries?
barelyauser··on Ask HN: Any live updates on superconductor replication?
Ceramic permanent magnets generators are used in windmills. The comparison you made with ceramic blocks for internal combustion engines is nonsense and honestly it appears you brought it up solely to reinforce some bias of yours. If you have nothing to contribute to the topic I suggest you refrain from misleading others.
barelyauser··on Some alloys don't change size when heated – recent work on why
Your "modern" cars have cooling loops for their battery, therefore cyclic thermal fatigue.
barelyauser··on Some alloys don't change size when heated – recent work on why
There are problems that are game stoppers and there are problems that are unavoidable. Cars work. Yes, if you drive 1 million miles you will have cracks in the engine due to thermal expansion, but who cares? Make a new engine and get over it.

Now consider a space elevator. Material problems are a game stopper.

barelyauser··on Some alloys don't change size when heated – recent work on why
Not high melting point but its ability to remain strong at high temperature.
barelyauser··on Kids Online Safety Act is still a danger to our rights online
Yes, keeping them oblivious of the very thing central to modern society will surely prepare them well.
barelyauser··on The first room-temperature ambient-pressure superconductor?
There is always low range broadcast I suppose.
barelyauser··on The first room-temperature ambient-pressure superconductor?
Communication satellites only changed the world because they broadcast to mass produced receivers.
barelyauser··on The first room-temperature ambient-pressure superconductor?
It is not limited to 250mA overall. A physically larger specimen would be capable of more current.
barelyauser··on 'Mystery company' buys land worth $800M near Travis AFB, raising concerns
It's not paranoia if they are really after you.
barelyauser··on A.I. Companies Agree to Safeguards After Pressure from the White House
> "Deploying advanced artificial intelligence tools to tackle society’s biggest challenges, like curing cancer and combating climate change."

Put in other words, we tell you what your products must do. It just stinks.

barelyauser··on Human Shader
I claimed a pixel and computed it using a calculator.
barelyauser··on In 1961 a Gallup poll showed only 33% of Americans in favor of moon landing
Let the taxpayer risk their money while private enterprise keeps all the intellectual property.
barelyauser··on Ask HN: What are you doing to fight climate change?
If you want a better future for your children then you should be saving money. With AI on the works, the future don't look very good for those without capital.

Believe me, you are not making difference you think you are doing. All the wealthy people I know don't care. I know a guy who flew more than 50 times last year, private jet and most of the times only he, the pilot and a third person. The less wealthy, who also emit a lot, don't care either as they can't afford to save the planet. Just look at Billionaire's row in NYC.

barelyauser··on Amazon’s in-van surveillance footage of delivery drivers is leaking online
Consider the following. There is a computer controlled machine gun aiming at you. Somehow it knows that it should not aim at any distractions you try to create. I would call it somewhat intelligent. Of course, I am more intelligent. Using a printer I'm able to fool it into shooting a piece of paper. Unfortunately I did not account for another "intelligent system" of the machine gun, it does not fire more than 5 rounds per face, and I'm out of ink for my printer.
barelyauser··on Southern Europe in extreme heat, with Greece seeing temperatures of 40C or more
Earth heats up. Water evaporates. Clouds reflect sunlight. Earth cools down. Oceans absorb more CO2. Mother nature saves us. Or does it?
barelyauser··on Southern Europe in extreme heat, with Greece seeing temperatures of 40C or more
We can solve it ourselves, we just don't want to.
barelyauser··on Ask HN: Is the Market Recovering?
Interest rates are on the rise. Money is expensive. Not recovering this year.
barelyauser··on SpaceX is stretching the lifetime of its reusable Falcon 9 boosters
James Cameron spent 10M to built his submarine. It is impossible at present time to build a orbital manned rocket for that amount. Therefore the submarine is easier to design and build.
barelyauser··on Ask HN: Any hardware startups here?
What is the COP of a heat pump operating against this temperature gradient?
barelyauser··on Why is desalination so difficult?
Search for OTEC (Ocean Thermal Energy Conversion). Not necessary to build wall, just a big enough pipe to collect cold water from the depth. Then a special contraption will yield pure water from evaporation. Can be done virtually everywhere there is a deep enough ocean.
barelyauser··on Ariane 5 User’s Manual (2011) [pdf]
Pedantic and pointless.
