FlyMoreRockets··on How We Can Stop the Spread of Covid-19 by Christmas
How we can stop the spread of COVID-19? It is really very simple. Stay the fuck at home.

FlyMoreRockets··on Mars is not a legal vacuum
You can survive on Mars with protection similar to that required to summit Mount Everest. Mars is a little colder and a little lower pressure and you need oxygen for both.

As of June 2020, 110 countries are parties to the treaty, while another 23 have signed the treaty but have not completed ratification. In addition, Taiwan, which is currently recognized by 14 UN member states, ratified the treaty prior to the United Nations General Assembly's vote to transfer China's seat to the People's Republic of China (PRC) in 1971.

FlyMoreRockets··on There's a metal asteroid out there worth $10k quadrillion
>In the long long term, isn't it reasonable to assume that Earth may end up losing mass due to space launches?

No. It is much more likely that Earth would become a long-term importer of space manufacturing for quite some time. It is much cheaper to drop stuff down into Earth's deep gravity well than to hoist it up into space. Pretty much everything in orbit (except for the Moon and mass where the Moon's gravitional influence dominates) will eventually come back down to the Earth's surface, too

> Either way your going to need fuel to move the material to earth. Energy to process the material ect..

There is unlimites solar power in the asteroid belt, 24/7.

If you were really desparate, a solar furnace could vaporize mine tailings and accelerate it through a nozzle for thrust. It wouldn't be efficient, but it is pretty much free, (except for shipping and handling). Kind of like that classic black and white movie where they are breaking up the wood of a box car to feed the steam engine pulling the train.

Literally every new car sold today uses plasma coatings to extend the lifetime of the rotating assembly and efficiency of the combustion facing components. Every commercial airliner turbine uses this technology, not to mention GPS, communication and weather satellites...

Move polluting heavy industry and manufacturing off planet, There are uncounted resources in the asteroid belt and 24/7 solar energy.

> We could "spin" the anti-space side as a religion too I suppose. It involves a bit more ascetism and self-flagellation though.

And a heavy dose of fatalism.

There are hundreds of asteroids that have more wealth than the entire US federal debt.

Consider all the precious metals ever mined on the planet. Now consider this is litterally scratching the surface of the total contained within the planet. Note, these dense metals will be concentrated toward the planets core, due to gravity.

The asteroid belt easily holds our planet's mass, but it is all spread thinly and relatively easy to access.

FlyMoreRockets··on Ask HN: Why isn’t finance a part of the core curriculum at schools?
Living month to month from cash reserves is the general way to describe this mindset, and is is the reason the nation sees a significant increase in purchases of durable goods when tax returns roll in each spring.

Your idea of daily payouts is a very clever hack on the system and deserves a practical trial. It would be most interesting to see if it encourages inceased savings on this scale.

The limited experience we have with digging on the moon suggests when you get past the initial few centimeters of dust, it is hard as a rock.

Delta T? Please explain. I'm familiar with DeltaV, but pretty much all the delta T usages I have seen refer to a time interval.

FlyMoreRockets··on No-till no-herbicide farming system in trial since 1981
Each year, I grow an increasing amount of my food from less than an acre. Corn is not an efficient way to get calories in an organic system, it requires too much nitrogen. As others have mentioned, potatoes are much better. And beans/peas, which require achieve their nitrogen requirements via bacterial symbosis. If you really want to go efficient, grow Azolla. I once calculated that a person in a temperate climate could produce most of their nutritional requireents with a plot roughly 25 square meters. Azolla doubles in mass every 2-3 days in ideal conditions and draws everything but trace minerals from the atmosphere.
FlyMoreRockets··on Windows Calculator Runs on Linux
This takes me way back to the Win 3.1 days, where I used the calculator, Notepad and looping the macro recorder to do number of calculations and optimizations. There were a number of special characters Calculator accepted to make this feasible. After all this time, the only one I can remember is p for pi.

Microsoft's cloud went down, taking all dependent services with it.

People have been saying this for decades: do not depend on Microsoft for mission critical services. Just did a quick search for an early Microsoft licence to no avail. IIRC, the license specifically stated that one should not use the system for any application where a human life hung in the balance.

Would appreciate any source for an archive of Microsoft license agreements.

FlyMoreRockets··on The fresh smell of ransomed coffee
You should know there is a coffee machine that can be set by a timer, that take raw beans, roasts them to a set level of darkness, grinds them and makes a pot of coffee. I was given a broken one a while back, should probably get it working and hunt down a source of raw beans.

This sounds like an opportunity to work with a lower tier race team to build reputation. Cool thing about racing, to the limit of the rules, the sport as a whole is receptive to the advance of technology if it confers a competitive advantage.

DC-3 airframes are still flying and often refitted with turboprops. The original radial engines are getting expensive to maintain, parts are getting tough to source.
FlyMoreRockets··on Paper maps, two-way radios: how firefighting tech is stuck in the past
Exactly this. I spent decades as a FF/EMT and that's the way it was typically done.

I did however, often carry a Baofeng programmed with _all_ the services with which I was likely to interact as a backup: MedEvac, EMS, law enforcement and fire services. Yes, I am a licensed ham operator.

The problem is there is no national emergency interop frequency plan, each state, county and city does things differently.
