aeternus··on A Black Hole Engulfing the World's Bond Markets
It benefits those with lots of debt but really hurts those that have worked hard to build up savings, or are on fixed income.
aeternus··on More money than anyone imagined: an explanation for why the bubble never burst
It is being addressed. Not at the level of governmental cooperation, but some of the things that really matter are being done in spite of that.

Solar cell prices have decreased by 300x over the last 40 years and continue to do so. Similarly, solar production capacity and installations have increased very significantly.

There are also more electric car companies and models than ever before.

aeternus··on Europe embraces rent controls, a policy that never works
No, because rent-control disincentives new development.
aeternus··on More money than anyone imagined: an explanation for why the bubble never burst
Education is more accessible now than ever. It's amazing that anyone anywhere in the world can watch Feynmann and Leonard Susskind's lectures on General Relativity without giving a penny to CalTech/Stanford. There is also plenty of cheap housing in the US, just not in large cities and highly desirable areas. If you do decide to live in a low-cost area, there are more options for remote work than ever before.

Over the last 20 years, humans have really mastered cooperation on a global rather than a national scale. IMO, the economy as a whole has expanded as a result.

aeternus··on Square’s Growth Framework for Engineers and Engineering Managers
An IC can definitely have and maintain more control than managers, they just need to produce visible value to the company.

I've seen multiple ICs with more power than their direct manager. They are basically immune to being fired because higher-level leaders understand their value and respect their track record.

aeternus··on Approaching Peak Housing Dysfunction in California
Is housing "going wrong" simply because it is expensive? Maybe it is overall a good thing that tech companies are now expanding into cities outside the bay area due to high housing costs.

At least housing prices are transparent to those thinking about moving in to the bay area, allowing them to make an informed decision. High traffic, insufficient public transit capacity, and over-capacity public services are less transparent. If we build more housing, do we just push problems elsewhere?

How do we determine the optimal amount of new housing?

aeternus··on NASA’s Lunar Space Station Is a Great/Terrible Idea
There are multiple launch systems that will have the payload capacity to go straight to the moon within the next few years. Why not just use those?

No one will care about a Lunar space station, it's not enough of a step forward to capture the public's attention. It's sad that NASA's 'futuristic' new proposal is to do half of what we were able to do 50 years ago. People will quickly vote to cut funding for it, and maybe they should.

aeternus··on Netflix CEO may have missed the real reason why US subscriber numbers plunged
Which Netflix shows would you say match the quality and viewership of GoT, Breaking Bad, Westworld?

Maybe only House of Cards. HBO just has Netflix beat in terms of content over the last couple years especially.

aeternus··on Don't donate canned goods to food banks (2017)
Most of the larger charities simply spend more of their budget on marketing. Is that desirable, and should the charity leadership be compensated handsomly for that?

It's a tough question as they may just be redirecting money away from charities with less marketing spend.

aeternus··on Landfill is underrated and recycling overrated
It's not magical thinking, landfill mining has been in-use since the 1950s: https://en.wikipedia.org/wiki/Landfill_mining

If certain resources do get more sparse, it will easily become economically viable to expand landfill mining and we already have the technology required to do so. At the end of the day, it's an energy question more than anything. With cheap solar plus the fact that landfills produce their own free energy (methane) there is no need to be alarmist and consider them a threat to our species.

aeternus··on Landfill is underrated and recycling overrated
Pretty much all paper manufacturers are now require to plant more trees than they cut down.

Burying old newspapers in the ground is a form of carbon sequestration. Really it comes down to what takes less energy: cutting down the trees, or the transport, sorting and reprocessing of old newspapers.

aeternus··on Crispr is less like molecular scissors and more like molecular malware
Yes, I think a better analogy would be an antivirus program that simply deletes any file (or more accurately parts of a file) it thinks is suspicious.

.. by no means an optimal antivirus program, but in a sense, it is effective.

aeternus··on Will Graphene Batteries Overtake Lithium?
Right, very little content. Also Graphene batteries are already out and unfortunately they perform about the same as regular lithium batteries.
aeternus··on Hit by Big Loss, Bird Seeks $300M in New Funds
People said the same thing about both horses and cars around cities.

If we can replace some of the cars with scooters it should be a net gain for citizens.

aeternus··on Seattle Faces Backlash After Easing on Crimes Involving Mental Illness
This assumes everyone wants to get better. As demonstrated here, not everyone does: https://youtu.be/bpAi70WWBlw?t=913

What do you do in cases like that if prison is off the table?

aeternus··on Seattle Faces Backlash After Easing on Crimes Involving Mental Illness
Look closely at the questions those surveys are asking. "Where were you living at the time you most recently became homeless" isn't the right question as there are temporary housing options (crashing with a friend, living in a vehicle) under which many do not consider themselves homeless.

From your own link, only 25% were born / grew up in King county.

aeternus··on Moving the World to a 4 Day Workweek – An Interview with Aidan Harper
What industry to you work in, and how large of a company is it?

Sounds like a great opportunity for a more efficient competitor to undercut this company :D

aeternus··on France to tax flights from its airports, airline shares fall
The tax should come first. Price incentives are strong, they will drive consumer behavior which will drive business behavior.
aeternus··on A Giant Asteroid of Gold Won’t Make Us Richer
Interestingly, this is the mechanism by which the Astroid may actually make all of us richer.

It will require inventions and new technologies to successfully mine the asteroid, and those will give society access to vast new resources.

aeternus··on Ask HN: Why is HN so aggressively anti-Bitcoin?
It would probably be better to address the root problem. Unfortunately replacing governments has a long history of being a very violent and bloody ordeal.
aeternus··on Ask HN: Why is HN so aggressively anti-Bitcoin?
True there is a lot of speculation today, and transaction fees are much too high to use for everyday expenses. I would say store-of-value is a valid use-case though. The ability of an individual to store wealth in their brain is a useful property. Mostly for those attempting to escape oppressive governments, or "extractive" political institutions.

The transferring of bitcoin is not what is energy intensive. The energy is expended as a "vote" on which of many possible forks should be trusted. Gold definitely has this expenditure as well, military's are often required to secure it, and large amounts of energy and expenditure are required to discover and mine it.

USD is one of the most stable currencies in the world, and the fed has done a good job of maintaining stability. You're right that Bitcoin is no where near as stable as USD, but it is more stable than the currencies of some other countries. There are still ways for a central bank to maintain interest rates even if Bitcoin is widely used. Bitcoin does not prevent fractional reserve banking.

aeternus··on Ask HN: Why is HN so aggressively anti-Bitcoin?
Very valid criticisms, but they do not apply in all cases.

In terms of reducing governmental control, sure this isn't much of a problem if your government is altruistic. Governments do not have a great long-term track record here. In Venezuela for example, many would say Bitcoin is solving a very real problem. You're right about its ability to be used for illegal activities, however the same could be said for most technology: encryption, the internet.

In terms of energy, this can be a criticism of almost all currencies and stores of value. This real-world expenditure is much of what gives it value, especially early on. Gold is valuable because of the difficulty in mining/acquiring it. Even national currencies are valuable due to the resources committed by their military, or the military's of that nation's allies. People might argue it is GDP, but GDP does not mean much if you cannot defend it.

Manipulation and price swings are a valid concern, but no other currency is immune to those either. Silver for example has had very widespread manipulation in the past. Silver and gold have probably still been a net-positive.

aeternus··on Paper Books Can’t Be Shut Off from Afar
Paper books can however be "shut off" by a fire, by being misplaced, by a flood, by theft, by a mischievous child or pet. In contrast, an e-book linked to a user account is immune to all of those.

If the idea of losing access to some data is the "most grotesque and awful thing" the author can imagine, I suggest the author read some more imaginative books.

aeternus··on The California coast is disappearing under the rising sea
Draining the bay is probably too extreme, but much of SF is already built on reclaimed land. All of Embarcadero, Mission Bay, Southbeach, even parts of Rincon Hill were underwater in the 1800s: https://upload.wikimedia.org/wikipedia/commons/9/9d/1858_U.S...
aeternus··on Django's goals are probably not our goals for our web application
Unfortunately it's not practical because the test matrix explodes. They would have to develop and test every security update on every previous version which is quite costly, especially if the codebase has diverged.

The best strategy is probably what many large distros like Ubuntu have adopted: designate only a few long term support (LTS) versions, and commit to supporting only those versions.

aeternus··on How to pick a random number from 1-10
Quite a few, anchoring is pretty interesting and can often be completely subconscious.
aeternus··on A Learning Secret: Don't Take Notes with a Laptop (2014)
The problem is that word processors and word wrap make it too easy to move text, destroying the absolute and sometimes even relative position.

Much of human memory evolved to remember locations, and almost all of the top memory competitors use locality association ("Memory Palace"/loci) as their primary method.

aeternus··on How to Land on the Moon
The idea that a rocket sitting on top of a column of thrust is significantly different than a rocket suspended underneath a column of thrust is actually a common fallacy, known as the pendulum rocket fallacy: https://en.wikipedia.org/wiki/Pendulum_rocket_fallacy

You are correct that longitudinal stability is applicable and important for most aircraft, but that is due to angle of attack and lift forces. Neither of which apply in a vacuum.

aeternus··on What Happens After Amazon’s Domination Is Complete? Its Bookstore Offers Clues
They are definitely tracking suppliers, but it is not as easy as you make it seem.

Suppliers may not be using 100% fakes, making them much harder to catch. Customers may also be a significant part of the problem, due to Amazon's return policy. Customers can easily claim a fake, then ship a fake item back, blaming the supplier.

There's no way to know for sure without Amazon themselves testing the products, which would be costly. Most items do not have unique serial numbers, and even if they did, opening boxes to confirm matching serial numbers would likely be cost prohibitive.

aeternus··on The age of electric flight is finally upon us
Bye Aerospace also has a pretty cool all-electric trainer aircraft that looks quite promising, and close to certification:
