High quality, slow motion video: https://x.com/dwisecinema/status/1935552171912655045

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

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.

If I ask ‘ Linux "sort" command line for sorting the third column containing integers’,

Wow, that's actually quite a lot. You can also just say "sort 3rd col nix."

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.

I did exactly that, and it was very close to the actual sklearn output.

I tried with alternate values and got the same result - not quite precisely exact, but extremely close values.

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.

Because they're not even remotely comparable products

I was also amused by a UX complaint on a site that is totally borked in a non-obvious way on Firefox.

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.

Fly the drones in pairs? Relay drone goes to a significantly higher altitude in the middle?

Claude has absolutely no idea how many deaths occurred as a result of this outage.

It's scary that people are taking these hallucinations as some sort of reasoned fact, or important opinion.

That's exactly what Elon has said. He's said that 99.99% of all vehicle miles are useless from a training perspective.

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.

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.

It's not double counting, it's just the average difference from CPI vs McDonalds hamburger inflation

McDonalds burgers were 15¢.

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.

It was two years of effort from at least one guy and more likely a team.

You think these guys have standups?

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:

This is why driverless cars are still just demos

Not directly the point of the article, but is it fair to say driverless cars are still just demos when they're operating on every street, road, and freeway from San Francisco to San Jose, with tens of millions of passenger miles?

I feel like once there are paying customers sitting in the vehicles, it's not a demo, it's a reality.

I'm perplexed how you're talking about this like it's a common problem people have had, something that's been ongoing for years.

There is no stuttering problem on audio playback on any of the smart phones you've listed. And there hasn't been any stuttering problem since the initial launch of the first generation iPhone.

The last time I remember any stuttering on any phone I've owned was maybe the Motorola Rokr twenty years ago.

You must have some sort of accessory problem.
