This is awesome. I went looking for FarFarOut ( https://en.wikipedia.org/wiki/2018_AG37 ), maybe would be cool to add it?

Great suggestion, just added it. Thanks for teaching me about FarFarOut.

Which has upkeep costs due to living in it, and the occasional overnight parking expenses and fines.


Cheaper than rental costs (in Australia), additionally Australia has excellent "Grey Nomad" facilities as a very big country relative to a small population (same land area as 48 state mainland US, ~ 25 million pop.).

It's always been a country of swaggies, less so now, but working on the move and camping are in the DNA of many.


There are manufacturing processes that benefit from microgravity (e.g. growing protein crystals for the pharma industry, producing semiconductors, etc).

Beyond that it would be a significant boon for science.


Semiconductors and microgravity, can you elaborate on what part of the production process would be improved?


There's a paper on the subject here: https://osf.io/d6ar4/

Seems like the primary benefit comes to silicon wafer manufacturing. Growing pure silicon crystal is much easier to do in a microgravity, vacuum environment:

> The study reported that for semiconductor crystals processed in LEO compared to terrestrial samples, more than 80 percent improved in either one or a combination of structure, uniformity, reduction of defects, and/or electrical and optical properties–and some by orders of magnitude

For actual device manufacturing, there are potential benefits as well, but this is less well researched area (possibly as a result of the difficulty of getting advanced IC manufacturing equipment into earth orbit).


I do somewhat doubt that the economics would work out. Silicon wafers are expensive, but I'm not sure if the price is currently higher than that of launching a bunch of sand to low earth orbit.


You wouldn't launch sands to LEO, but the equipment used for bootstrapping a mining operation on the moon or asteroid.


I think the point is you'd be able to build products in space that you cannot build on Earth for any cost currently.


You can 3D print organs in space that you can't in Earth, there was just a successful trial of printing a knee meniscus.

https://www.issnationallab.org/redwire-space-3d-prints-menis...


What fraction of machine time is currently spent pumping wafers down to molecular-beam vacuum? What fraction of machine mass is dedicated to holding that vacuum? Vibration isolation would also be much easier. Not sure if these are enough to matter, let alone enough to justify a rocket, but maybe the math can be made to work.


1 billion SATS = 10 bitcoin

1 SATS = 0.00000001 bitcoin

Unsure why the headline was edited. Probably to get more attention as btc draws more attention than SATS


> Probably to get more attention as btc draws more attention than SATS

No I just think that an amount that is equal to several BTC is pointless to measure in sats.

It’s equally pointless to use sats as the units of measure for such a big amount, as it would be to say “20 million cents” instead of just “$200k”


also basic conversions don't work on Google / ChatGPT.

Google told me 1 billion sats is 0.1 BTC, ChatGPT 0.01 BTC. Google was still closer :)


This sounds like scaling the service to more areas will slow :( . Surprising that Alphabet sees the savings to be worth a slower rollout.


Well... It's not like it can get any slower, can it? Waymo is the industry lead and yet it offers rides to only a small closed group of beta testers. They only deploy it in geofenced areas. It seems that they deploy the driverless variant, but every Waymo I ever see has a driver behind the wheel, driving it manually, night time or daytime. This rollout is glacial.

It's been 16 years since the DARPA Urban Challenge. I'm happy to be wrong, but I really don't think robotaxis will penetrate the market to mass adoption like many predict, and if it does, it will be in 50 years or more. In 20 years robotaxis will still be a problem of legislation and struggling with adoption, not a technological problem. American car culture is too ingrained.

At most, driverless robotaxis will be symbols of tech companies along the coastlines. They won't transform transportation for the working class because in 20 years, 95% of drivers will still want to drive themselves.


You say "along the coastlines" like that's supposed to represent a tiny sliver of the population. In fact, depending on how exactly you define coastline (does the gulf of Mexico count?), probably the majority of the population lives "along the coastline".

As for the definitely landlocked populations, they have already been enjoying the benefits of self driving vehicles for many years in the form of autosteer on their tractors.


"yet it offers rides to only a small closed group of beta testers."

Not true, anyone in PHX can use the Waymo App and hail a robotaxi.


> At most, driverless robotaxis will be symbols of tech companies along the coastlines.

40% of the US population lives in coastal counties, so... Okay.


This looks amazing, but installing the Firefox extension I am worried about all the permissions it asks. I am surprised how comfortable people are signing off on these permissions. How do people at HN put these security worries to rest?


This (your fear) is a result of bad policy by Firefox. This is why a lot of useful add-ons or plugins died, and, overall, Firefox became a shittier browser.

Neither Vimium nor SurfingKeys don't hold a candle to KeySnail because back in the days add-ons worked you could control the browser's chrome as well as a bunch of other non-HTML elements.

Today, you cannot even use browser extensions to close a browser window if the page didn't load in it.

These tools were intended for "power users", who could establish for themselves if the piece of code they want to use is doing something malicious or not. Also being an easy way to extend the browser without a need to recompile it and a need to understand a huge project with a ton of infrastructure... flushed down the drain.

This reminds me about how Alan Key said in one of his interviews that if a motorcycle was invented today, it would've been outlawed right away due to safety concerns.


Auditing each tool by ourselves would cost a lot of time. Not to mention that it would not be a one-time thing. At each update, another check would be required for "peace of mind".

Curious to discuss if there is a way to trust these extensions without establishing ourselves that the code is not harmful.


But you don't audit it entirely by yourself. Nor were you expected to before. It's the same idea as with other programs or add-ons you use. Don't you use some add-ons in the code editor you use not authored by the authors of the editor itself? And why would you believe the authors of the editor in the first place?

Of course you need to do some due diligence, but it isn't anywhere near as taxing as you seem to think.

Security is worthless if it prevents you from doing useful things. Given a choice between a chance of security breach and not being able to do the useful thing at all, in the circumstances like using a Web browser, I'd definitely choose to have the useful thing w/o security.


It seems it would depend on the persons risk tolerance.

And assessing risk of freely available open source software is still difficult, you either rely on all the authors being standup citizens, or on the bulk of the reviewers to be truthful and knowledgeable.


It's open-source, about 10K lines of good quality self-contained JS code with no obfuscation so it's not that hard to go through it yourself. It moves fairly slowly these days so once you have done this once it's easy to stay on top of the changes.


I guess for me it’s a combination of:

* The extension has a genuine need for the permissions

* It’s an old extension at this point, with known maintainers with names and faces

* I really, really want the features


Curious, what is the reason you would consider buying more than 1?


Work and personal, but also as dedicated offline password managers. If I don’t need camera functionality or wifi, then can simply pop those out. The options are endless.


Spare parts?


Could you please explain in more detail how a CEO of a profitable massive corporation signaling desire to pay higher corporate income tax is a loss for the economy and the common man.

If anything he might be suggesting in the letter that corporations aren't paying their fair share relative to the common man.


Because the the largest corporations often clamor for more taxes and/or regulations knowing that it hampers their competitors more than them.


It is a moat and keeps the status quo.

He understands how finance works, and he understands how compound interest rates work; he got the benefit of "low interest rates" on taxes and generated a lot of wealth; if he increases taxes for upstarts and himself, the upstarts are harmed more, since he has the legacy wealth from the historical discount.

Aristocrats made the laws favor themselves, and since they already owned all the land and wealth, no one was going to challenge them inside the legal framework.

There is a tendency, once you make your own fortune, to get political influence and make laws that make it harder for others to do the same thing. Change the rules of the game so you can't fall. Lobbying is a key business skill these days.


corporate taxes are _always_ passed on to the consumer.

Higher fees, higher prices, whatever lever you can pull.


That's not true - they are not always passed on to the customer. It depends. Unless the corporation has a monopoly, it can not just increase the prices. There is a concept in economics called elasticity of demand, to simplify, it states that with increase in price there will be a drop in demand. So corporations have to balance, and in most cases the tax increase will be shared between the consumer and the corporation.


They might not be the CEO of that profitable massive corporation for much longer if the board and shareholders do not hold the same sentiment.


To put it simply, private businesses will allocate capital more efficiently than the government does. (At least a few people still think that.)


The “direction” of that efficiency is always toward profit and against the very laboring class that makes the product the owners use for profit.

With a collective, co-op, employee owned, or government run industry - one can edict the various rates and ratios.

Look at the US energy company “eversource.”

Posting huge profits in an industry directly related to life and health and yet, doubled one of its rates this year. DOUBLED. Why? “Fuel costs”.

Fuel costs which have fallen.

With a gov run electric system, people will game based on votes. Not shareholder ROI.

Plus, people have a very “interesting” history when they disagree with a gov. From protest to removal of heads from bodies...

It’s not as simple when corporations are involved.

They are more evil than any of history’s evil men.


If corporations are accepted to be "evil" (and we have lots of examples of mega-corporations that haven't held to "don't be evil"), then simply taxing them and having them continue to be evil doesn't make a lot of sense. Perhaps it would be better to abolish corporate structures and find a new paradigm with greater personal responsibility with small companies more responsive to customers and their customers' values? If people feel responsible for their actions, then they are more likely to "not be evil", instead of being a raindrop in the flood that believes they should just do as they are told. A large part of the US economy is small business, small businesses can live by their values instead of the inexorable pull towards more profit. I'm not saying all small businesses do, but it's more of a personal choice of their values and their customers' values rather than a large tendency to "become evil with more profit and seeking monopolies".


Completely agree. In my opinion a solid start is worker-owned co-ops.


Question is if they allocate it in ways the democratic majority wants it to be allocated.


Or skip the middle man and let people keep their dollars and spend them how they want?


How do you decide on the path the road should be built on? Everybody building a few feet individually?


Most people are not debating the building of roads, and most of those are at state and local levels anyways. The bigger debate is on the actual federal budget, which has ballooned over time into all sorts of items which cannot be assumed to be uncontroversial or even generally agreed on by a majority of citizens.

A lot of us would prefer if the federal government actually did allocate some more of its funds to maintaining the roads and infrastructure that we have; that would be a great start.


They probably agree that A road has to be built, but exactly WHERE gives you about as many opinions as 5hwre are participants in the discussion. This requires some approach for structuring the decision making. Representative democracy is one. And yes, for such hands on topics it is relatively simple. But "big topics" have equal problem with many opinions, where some form of consensus has to be found.


Warren also seemed to strongly hint (quoted below) that Treasury should be getting more of its revenue from corporate income tax. Maybe your quoted part was him reinforcing that point and putting BAs money where its mouth is.

"The $32 trillion of revenue was garnered by the Treasury through individual income taxes (48%), social security and related receipts (34 1⁄2%), corporate income tax payments (8 1⁄2%) and a wide variety of lesser levies. Berkshire’s contribution via the corporate income tax was $32 billion during the decade, almost exactly a tenth of 1% of all money that the Treasury collected. 8

And that means – brace yourself – had there been roughly 1,000 taxpayers in the U.S. matching Berkshire’s payments, no other businesses nor any of the country’s 131 million households would have needed to pay any taxes to the federal government. Not a dime."


I don't get the enthusiasm for raising money from corporate income taxes versus individual income tax. Mr. Rich Moneybags pays the same corporate income taxes per share of Berkshire as Joe Schmoe, whose entire retirement pot might be a single BRK.A.


Mr. Rich Moneybas probably pays no personal income tax, and certainly pays a lower effective rate than Joe Schmoe.

Taking the tax money as corporate tax means they end up paying the same percentage, without Moneybags’ CPA leveraging shell companies and loopholes to avoid tax than Schmoe pays.


Rich moneybags never has to sell. He can just take out a margin loan and skip the taxes.


Surely you can't loan into infinity and have to sell at some point to start paying off the debt.


Suppose I have 100 million in my investment portfolio and a 5% interest rate. I want to buy a house for $10 million. So I withdraw 2 million in cash and get a margin loan for 2 million so I don't have to sell any securities. I take the 2 million in cash, get a mortgage for 8 million, and buy the house. On average the market returns 7%. So my $100 million portfolio is earning $7 million per year less the loan interest of 100k which comes to $6.9M. After 2 years I pay off the mortgage and repay the margin loan. I now have a house and I didn't have to pay any taxes on my securities to buy it.

What if the market goes down? Well, I just wait for it to go back up again. I can easily afford to wait, my margin of safety is huge. Since the margin loan is for 2 million, and I need a 50% margin of safety by law, then the portfolio value would need to decline to 2 million (98% decline) before my loan gets called.


"...and don't call me Shirley"


Because of the class difference between working/labor and capital owning classes. One has a hedge against bad decisions based on the backs and labor of the other.


The U.S. government's total revenue is estimated to be $4.71 trillion for FY 2023.


The $32 trillion figure in the letter is tax revenue over the decade ending in 2021. Berkshire's $32 billion (0.1%) is over the same 10-year period.


Could you elaborate on "the way reviews are incentivized". As I understand it, guests review of the host is only visible to the host after the host has also reviewed the guest or a deadline has passed.

Do hosts look at the reviews the guests have left to previous hosts and that incentivizes the guests not to give bad reviews? Or am I missing something?


Yes, if you give sub-five-star reviews it seriously messes with the hosts’ bookings, from what I’ve heard. And it’s pretty common for one person to manage a bunch of properties for the owners, so a bad review is messing directly with that person’s livelihood. The profit from your booking is not worth the risk of a negative review.

Additionally, I’ve heard stories of negative reviews getting “disappeared” but I’m not sure how that works.

Tangentially: this is why I read lots of reviews before booking, because you can sometimes spot rotten host behavior hiding in the five-star reviews.


this is precisely why a bad review should be left for hosts doing this sort of practice. They are likely running this across large operations, extorting “hidden fees” from each stay at each property.

Their profits should be systematically targeted if the fees are undisclosed upfront and they’re abusing it.
