Comment Re:Seriously (Score 1) 24

The Switch 2 pricing was announced well after Trump was elected, and undoubtedly included *some* additional markup for tariff increases from the get go, since he had been talking about tariffs the whole campaign, even if it has been a continual game of roulette trying to predict the *exact* tariffs. So it makes sense that the Switch 1 prices would be more sensitive to the tariffs than the Switch 2.

Comment This is Ricardoâs theory of rent (Score 4, Interesting) 48

In case you never took that course, the classical economist David Ricardo figured out that if you were a tenant farmer choosing between two lots of land, the difference in the productivity of the lands makes no difference to you. Thatâ(TM)s because if a piece of land yielded, say, ten thousand dollars more revenue per year, the landlord would simply be able to charge ten thousand more in rent. In essence landlords can demand all these economic advantages their land offers to the tenant.

All these tech companies are fighting to create platforms which you, in essence, rent from them. Why do you want to use these platforms? Because they promise convenience, to save you time. Why do the tech companies want to be in the business of renting platforms deeply embedded in peopleâ(TM)s lives? Because they see the time theyâ(TM)re supposedly saving you as theirs, not yours.

Sure, the technology *could* save you time, thatâ(TM)s what youâ(TM)d want it for, but the technology companies will inevitably enshittify their service to point itâ(TM)s barely worth using, or even beyond that if they can make it hard enough for customers to extract themselves.

Comment Re: This is why we need public health insurance (Score 4, Informative) 110

You should be careful of taking the claims of the Chinese Communist Party at face value. China has universal health insurance, but it is administered in a way that many people canâ(TM)t access critical care *services*.

For example if you are a rural guest worker in a city, you have health insurance which covers cancer treatment, but it requires you to go back to your home village to get that treatment, which probably isnâ(TM)t available there. If you are unemployed you have a different health insurance program, but its reimbursement rate is so low that most unemployed people canâ(TM)t afford treatment.

Authoritarian governments work hard to manage appearances, not substance. This is a clear example. It sounds egalitarian to say everyone has the same health insurance, but the way they got there was to engineer a system that didnâ(TM)t require them to do the hard work of making medical care available to everyone.

If you want an example of universal healthcare, go across the strait to Taiwan, which instituted universal healthcare in the 90s and now has what many regard as the best system in the world.

Comment Re:what does AI do when... (Score 1) 70

I would expect the AI to say "fix the core routing network" based on the last problem I had. It turns out the ISP's config is broken for IPv6 BGP via two different backends on their system to the same router on my end. I kept getting the BGP packets on the wrong interface so one link would never come up. I have no idea how that would happen but it did. Oddly the v4 BGP works quite well.

Comment Re:Meh (Score 1) 68

Yup. And TBH the shares haven't declined that much. $600b sounds like a lot of money, but Apple is trading at $200 ATM and peaked out at something like $230 or $240 when the market was hot before people realized Trump wasn't just talking shit about ruining the economy, but was actually going to do it. The fact that Meta is spending stupid money on AI at the moment ought to be frightening Meta shareholders, not Apple shareholders.

Comment Re: effective? (Score 4, Insightful) 131

The COVID mRNA vaccines were the culmination of decades of research into genetic vaccines that could be in essence engineered to target a selected antigen without the years of trial and error that are required by the methods we have been using since the 1950s. Within days of the virus genome being published, they had a vaccine design, the months it took to get to the public were taken up with studies of the safety and effectiveness of the heretofore untested technology, ramping up production, and preparing for the distribution of a medicine that required cryogenic storage.

It would be unreasonable not to give the Trump administration credit for not mucking up this process. But the unprecedented speed of development wasnâ(TM)t due to Trump employing some kind of magical Fuhrermojo. It was a stroke good fortune that when the global pandemic epidemiologists have been worried about arrived, mRNA technology was just at the point where you could use it. Had it arrived a decade earlier the consequences would have been far worse, no matter who was president.

The lesson isnâ(TM)t that Trump is some kind of divine figure who willed a vaccine into existence, itâ(TM)s that basic research that is decades from practical application is important.

Base load coal power in China is about $25/MWh. Solar panels by the container ship load cost less than $0.20 a watt at the factory. Most of that cost is the energy to make them. A good guess for daily average solar production is 4 hrs a day at 100% power for total power produced over the 20 year expected life of the panel.

Comment Re:Same "pilot" problem crashed the 737 Max's (Score 1) 248

You missed the part where all pilots were qualified to fly the 737 MAX according to Boeing. Well, Boeing lied.

This cannot be emphasized enough: Boeing lied.

I do not remember all the details right now. But in order to fit a larger engine with enough ground clearance, they had to change its thrust angle slightly. They told the FAA there were no changes that pilots needed to know about or retrain for. They lied, to airlines, to the FAA and to the public. The two crashes were due to pilots not knowing about the changes.

Comment Re: "far too small to generate any lift"?? (Score 4, Interesting) 106

That's how I read it. It should say it has no thrust.

A typical jet turbofan airframe has two engines that each have a generator shaft taking turbine energy and making electrical current. It then has a whole 'nother turbine engine used on the ground and in some other flight legs called the APU; this exhausts out the tail cone usually, and can start engines or provide extra hydraulic power if needed, but is slow to start just like the main engines.

For power loss emergencies, a small spring-loaded fan pops into action super fast, called a Ram Air Turbine or RAT. It can only make enough electrical power to reboot key systems like engine FADECs or avionics, often only on one electrical channel instead of all channels. It's only a turbine, not a thrust-producing fan. It's a pinwheel toy in comparison to the APU and even the APU cannot produce significant thrust.

Comment A poem by Howard Nemerov (Score 1, Interesting) 112

        Because I am drunk, this Independence Night,
        I watch the fireworks from far away,
        from a high hill, across the moony green
        Of lakes and other hills to the town harbor,
        Where stately illuminations are flung aloft,
        One light shattering in a hundred lights
        Minute by minute. The reason I am crying,
        Aside from only being country drunk,
        That is, may be that I have just remembered
        The sparklers, rockets, roman candles and
        so on, we used to be allowed to buy
        When I was a boy, and set off by ourselves
        At some peril to life and property.
        Our freedom to abuse our freedom thus
        Has since, I understand, been remedied
        By legislation. Now the authorities
        Arrange a perfectly safe public display
        To be watched at a distance; and now also
        The contribution of all the taxpayers
        Together makes a more spectacular
        Result than any could achieve alone
        (A few pale pinwheels, or a firecracker
        Fused at the dog's tail). It is, indeed, splendid:
        Showers of roses in the sky, fountains
        Of emeralds, and those profusely scattered zircons
        Falling and falling, flowering as they fall
        And followed distantly by a noise of thunder.
        My eyes are half-afloat in happy tears.
        God bless our Nation on a night like this,
        And bless the careful and secure officials
        Who celebrate our independence now.
