I was wondering how the scientists went from proposing a planet that was 1.5 to 2 times the size of earth, to proposing it being 5-10 times the size of earth.

Never been in a car with such a feature, as it seems inherently dangerous to me.

Every car I’ve been in, when you accidentally disengage the cruise, you just hit cruise again and it re-engages at whatever speed you slowed down to, then you adjust back to what you want.

Having the car suddenly accelerate without deliberate input just doesn’t seem wise.

According to the article there is a “resume” button for the cruise control.

No idea because I don’t own one of these, but if it’s true that’s insane.

I’ve driven a lot of cars from a lot of different manufacturers, and have never encountered a resume button that works how the article describes, where it will accelerate you to whatever the last cruise control speed was.

To add to this, we’re going to run into the problem of garbage in, garbage out.

LLMs are trained on text from the internet.

Currently, a massive amount of text on the internet is coming from LLMs.

This creates a cycle of models getting trained on data sets that increasingly contain large sets of data generated by older models.

The most likely outlook is that LLMs will get worse as the years go by, not better.

I remember a few career changes ago, I was a back room kid working for an MSP.

One day I get an email to build a computer for the company, cheap as hell. Basically just enough to boot Windows 7.

I was to build it, put it online long enough to get all of the drivers installed, and then set it up in the server room, as physically far away from any network ports as possible. IIRC I was even given an IO shield that physically covered the network port for after it updated.

It was our air-gapped encryption key backup.

I feel like that shitty company was somehow prepared for this better than some of these companies today. In fact, I wonder if that computer is still running somewhere and just saved someone’s ass.

Why does a fridge need to know your habits?

It has to keep the food cold all the time. The light has to come on when you open the door.

What could it possibly be learning

Don’t forget your sacred duty boys, dicks out for Harambe.

It’s the only way to fix this fucked timeline

Then what’s the point in having a day by day rate?

Bought iPhone last year.

Tried Apple Maps the first week.

Put in address to friend’s new condo building.

Took me to a parking lot behind a grocery store next to the building, and then acted like I could drive through an old wooden fence to get to the condos.

5/10 I only had to drive to the other end of the block to find the only entrance to the property.

I don’t think you really grasp how much pressure 10,000 psi is.

A typical car tire is like 35 psi

A propane tank for a grill is like 200 psi.

Have you ever seen a car tire burst? Or a propane tank? Big booms, they can easily hurt or kill people already.

A hydrogen tank would be 50 times more pressure than a regular tank of fuel, and 300 times more pressure than a tire. If those burst, people will die, and have their bits spread around the neighborhood.

An industrial machine designed to handle 10,000 psi gas is a little different from a tank you’d take to a BBQ.

A fuel station will also get resupplied regularly, so any small leaks are no big deal, as there will be a shipment of fresh fuel coming in a regular schedule. Your BBQ tank of hydrogen likely will need to be refilled regularly even if you don’t use it, as any valve that would be cheap enough to mass produce is not going to be able to keep hydrogen in for months while it sits in the garage.

Then there’s also the fact that most uses for gaseous hydrogen require the above 10,000 psi storage pressure. This allows a useful amount of hydrogen to be stored in a non-comically large container. 2 problems I see with this:

1.) a 10,000 psi container is fucking terrifying. If that things bangs into something and ruptures, it going to send shrapnel through a house.

2.) a propane like tank can be opened to the Atmosphere and does not have a regulator built into the tank because most people don’t know how to actually use a regulator. So a 10,000 psi tank with just a hand valve between the user and a jet of gas that can send the tank into the stratosphere does not sound like something that should be available at your local hardware store.

Hydrogen is very difficult to bottle. It tends to just slip out of anything you put it in because of how small the atoms are.

And also incredibly low density. So your bottle would likely be on a trailer.

Blazing saddles was written with the golden rule of offensive comedy: don’t punch down or up, punch in all directions.

I’ll yank your units

That’s why they made it a pin.

Sure you can sell an app on the App Store, but most people won’t pay more than 5 bucks for an app, and even that’s stretching it. And the subscription market is already over saturated. So how do you make a boatload of cash? Sell overpriced hardware that needs to be “upgraded” every year or 2 to use new features, and include a subscription to use the thing in the first place.

They wanted to pull an Apple and lock people into their hardware ecosystem. I guarantee there was a plan for them to release an AI phone in the next 5 years if this thing did well.

What they missed is Apple products are generally pleasant to use on a daily basis. From what everyone said, this thing was hot garbage and slow to respond to queries.

If it really did, then nasa would not have committed to this hare brained scheme of musk’s.

The fact that the SpaceX proposal was accepted by an interim director who then went to work at SpaceX 6 months later, and no one has investigated this or challenged the acceptance of this contract tells me that safety is clearly not the priority. If safety was the priority, the new director would have looked at the current proposal and demanded a renegotiation or reconsideration.

If only that philosophy existed today.

NASA landed on the moon with 1960’s technology, not because it was easy in the 60’s, but because every single aspect of the mission was planned, tested, rehearsed, and made as simple as possible where it couldn’t have a redundancy. The only time something went really wrong was when a faulty tank exploded on Apollo 13, but due to having an entirely separate craft in the form of the lander attached, the astronauts were able to ride out the failure all the way around the moon and back to earth. Oh yeah, even the orbit they picked would let the whole spacecraft fly around the moon and come back to earth without having to do any engine burns.

Look at planned missions today. Launch the Human Landing system. Have it sit in space for an unknown amount of time while anywhere from 6 to 12 refueling rockets are launched to refuel the lander. Relight lander engines in earth orbit, go to moon, relight engines again to orbit the moon. Launch the Orion spacecraft with crew on board, this also must burns its engines once at the moon to enter lunar orbit. Rendezvous and dock with the HLS, transfer crew and supplies over. Undock Orion, relight HLS engines for a 4th time to deorbit and land HLS. Use an elevator to get from HLS to the lunar surface for the next week or so. Board the HLS, which needed at least 6 refueling tankers full of cryogenic fuel to get to the moon and has now been sitting on the 200 degree lunar surface for a week, and light the engines a 5th time to take off and enter lunar orbit. Rendezvous with Orion, and return home. NASA has demonstrated that Orion can do the mission. But HLS has not even shown the technical capability of doing this. Its engines have never been relit in space, it has never sat in space for a week to see what happens to the engines. The entire interior isn’t even built yet and NASA is just using a 9 meter steel circle to train astronauts on the airlock section because no one knows what it will look like.

This mission couldn’t be more complicated if you tried. Apollo needed a total of 1 engine relight on the transfer stage, and 2 engine relights on the command module: one to enter lunar orbit, and one to leave and return to earth. The lander used pressure fed engines that only needed to work once each. One engine got them from orbit to the surface, one got them from the surface to orbit. If the Ascent engine didn’t work, NASA had plans for everything from literally jump starting it with the descent module’s batteries like it’s a dead car, to having an astronaut use bolt cutters to cut the safety pins on the engine so the valves can be manually opened.

If your car doesn’t start in the morning, you might call off work and get it towed to a mechanic. What do you do when you’re trying to leave the moon, and your rocket engines won’t light because they’ve been sitting in space for almost 2 weeks? The nearest rocket engineer is 240,000 miles away back on earth, and so are all the spare parts. And what do you do if only some of those engines light, and the others either don’t or explode while you’re on a suborbital trajectory. Complexity kills on harsh environments. Space is one of the harshest environment we’ve ever been in, so things need to be as simple as possible and known to work.

The fact that this was your take away is concerning.

No government service should have to show a profit. If it’s an essential service, then it needs to be done. The only time money should come into it is in regular audits to ensure the budget is being used efficiently.

Gotta love how the post office is legally required to show they can turn a profit, but the military has a history of building literal burn pits that essentially burn US tax dollars by lighting equipment on fire and giving soldiers cancer.
