Well, according to TFA, you're still paying an Amazon tax, which is itself similar to the Visa tax, which apparently we all pay even if we use cash to purchase directly from manufacturers (so long as the manufacturer also sells their product on Amazon).

There's a high quality slow motion video available [1] that shows the problem was almost certainly a failed pressure tank, not the engines.

Re:Moody’s strips U.S. of triple-A credit rating on Sunday May 18, 2025 @01:00AM (#44019106)
Because the major categories are very hard to cut:

Social Security: 22% Interest on the Debt: 14% Medicaid: 14% Medicare: 14% National Defense: 13%

That's 77% of the budget in those categories.

Everything else is 23%. The Federal deficit is ~25% of receipts.

You could cut each and every function of the government other than the above and still be left with a deficit. And there isn't a lot of room to cut everything else, as they've already been squeezed for decades.

Re:When Oregon blew up a whale with 20 cases of dynamite on Tuesday March 18, 2025 @02:38AM (#43396365)
The blown up whale in Oregon is sort of like the SR-71 speed readout story. Reposted endlessly, but you just kind of accept it.
Steel is by no means obvious. No one else in the industry uses it. (No one else in the industry uses carbon fiber, either, except things like fairings).

The obvious choice that everyone uses is aluminum, or various alloys, like aluminum-lithium.

There is absolutely no chance Starship is developed using steel without Musk. There is absolutely zero chance that Mechazilla would exist without Musk. These are massive elements of the Starship program.

Now, it's true enough that he didn't literally _build_ these things. He is the CEO. Steve Jobs didn't build the iPhone.

But these programs are very obviously shaped by Musk to a large degree.

It shouldn't be, though. There is way too much democracy in California localities.

There should be no elected school board, transit districts, utility boards, assessors, sheriff, and so much more. No one is properly informed about candidates for these positions.

For that matter, the Board of Supervisors should have no power other than oversight and impeachment. The Mayor should basically be a local dictator, with the power to do anything the State authorizes the municipality to do, at their sole discretion, with the oversight of an elected board.

> oxygenated atmosphere

Of course, the oxygenated atmosphere only exists due to life. Otherwise, it would just rapidly oxidize everything else.

Solar panels across the entire roof of a data center can't generate much more than 1-2% of the total power usage of the data center.

Would need a solar farm with about 50x-100x the land area.

AC is not harmful to the planet, carbon-based sources of energy are.

The ideological framing of the degrowth movement is all around us.

It's not totally broken, it shows the first frame of the image, there's just no indication at all that the image is actually meant to be a video, there is no play control, and it just looks like a static image.

> For the second test, my wife reluctantly gave me permission to try out FSD for interstate driving, which should be its best case scenario.

Except this isn't the new FSD stack, it's the old one.

It's a fair criticism of the current offering, but it's not much evidence against a future robotaxi.

The eventual plan is to build an orbiting space station, the Lunar Gateway. Astronauts will then launch on SLS/Orion, which will perform a Trans Lunar Injection.

However, before that, a Starship will be launched into LEO. There will then be something like 17 (the actual number is not clear, but it is a lot) Starship tankers that will launch to re-fuel the original Starship.

The Starship then does a Trans Lunar Injection. The Orion docks with the Lunar Gateway, Starship docks with the Lunar Gateway, the astronauts transition to Starship, which does a propulsive landing on the moon.

Re:BYD Launches Hybrids with 1,300-Mile Driving Range on Friday May 31, 2024 @10:47AM (#40535920)
Not really.

In a perfect world where we had an unlimited supply of batteries, charging infrastructure, and all-renewable electricity, BEVs would be best.

But we don't live in that world. Plugin hybrids with smaller batteries are likely the best path until we can scale the battery and charging infrastructure.

I mostly work at home, and when I'm coding, I generally have music on. I like to sing along with music, and I sit at my desk singing and coding all day long.

But I could never do this if I was reading something. It's impossible to read something and sing something else at the same time. But it's perfectly easy to do while coding.

Interesting. When the disaster first unfolded, a lot of experts came out to say the bridge appeared to lack protective barriers to help absorb the energy from a ship impact. [1]

However, the NTSB says the bridge did have these barriers. There were large protective "dolphins" directly in front of the bridge piers, but the ship managed to careen in between them at an angle, missing them, but still hitting the bridge.

In addition, there were large protective barriers surround the bridge pier that was struck:

> In addition to the dolphins, pier nos. 17 and 18 were each surrounded by a 100-foot-by- 84.5-foot crushable concrete box and timber fender system , as seen in figure 12. These systems were comprised of hollow, thin-walled , concrete box structures attached to the piers. The timber portions of the fender were attached to the outer face of the concrete box and utilized a combination of vertical and horizontal members. Additionally, steel plates were secured at the base of the vertical timber members.

It's worth noting that when George Sowers and ULA did their well-known business case analysis for re-use (nearly 10 years ago, in 2015), their analysis concluded that it would take 10 flights to pay-off the penalty of re-use.

The analysis was flawed from the start, because it falsely assumed you could charge for every kg of capacity, but in reality customers are largely paying by flight, and much of the Falcon 9 capacity is unused.

But even according to their flawed analysis, they assumed there would never be a need for so many flights, and re-use would just eat into their production line productivity, raising the cost of each rocket.

These false assumptions caused them not to pursue any real type of reusabilty. Though they proposed a janky system where the engines would be recovered by parachute and helicopter, they never funded it, and the current Vulcan doesn't support any type of reuse.

Flash forward to today, and ULA has a contract for possibly 83 launches from Amazon for Kuiper.

What a terrible lack of foresight.

Okay, it was the McDonald's hamburger that seems to have been $0.15 in 1963. That is $1.53 in CPI-inflated 2024 dollars.

The cost today is $2.19. That's about a 0.6% difference in the compounding inflation rate over 61 years.

You are conflating entirely different statistics. For every stat other than driverless vehicles, you used the fatality rate. For autonomous vehicles, you used the accident rate, and you included all manufacturers and a stat from 3 years ago.

The statistics that have been released from Waymo are significantly different:
