Well, it's the students, but humans are dumb, we make bad choices. That's kinda the whole point of being a child actually, to make all those bad decisions and learn from them. But any parent human knows that sometimes you just need to lay down the law, make some hard rules. Some lessons are hard to learn and enforcing some ground rules (like no cell phones in schools) will help you learn good habits for yourself.

True. But fuck them.

That's what we do in our house, I decided it was the easiest way to be sure my son actually lifts the seat. If he has to lift the lid, he'll just lift the seat at the same time.

This still seems fine... At that rate, electric will start to greatly outnumber ice cars. That has all kinds of knockon effects, for instance, selling fewer ice cars means their replacement parts will be less available, maintenance will get more expensive. Manufacturing these cars will also become more expensive because you'll lose some economy of scale benefits. So, ice cars get more expensive, while evs get cheaper. Meanwhile, petrol stations get significantly less business from petrol sales, it will become not economical for many stations to continue to maintain all their equipment. Some stations will close down.

The cars will get more expensive, the fuel harder to find, and I'm sure there are other things that will change as well. There will be enough incentives to make the remaining drivers switch over soon enough.

I expect that won't be necessary. Disney has the opportunity to get good PR out of this. All they need to do is sing this worker's praises, parade their hero around a bit, compensate him appropriately, pay for all medical needs, etc. All together a small cost for some good press and a happy ending.

I totally understand where you're coming from and I mirror the sentiment, 100%. I'm tired billionaires steering the country, and I'm especially tired of musk, I hope I never have to hear his name in the news ever again.

That said, I think your take is misguided. For all that I hate musk, spaceX has achieved some truly astonishing things. And not only have they achieved their goals, but they've done it at an unprecedented rate and at a shockingly low cost. SpaceX is developing technology at a similar rate to NASA way back at the beginning, during the Gemini and Apollo programs, except back then NASA was getting 4% of the federal budget. SpaceX has not had anything close to that level of funding. In fact, though they have most definitely taken government contacts, for the most part, they've been able to foot the bill themselves (and with investors) for the majority of their development costs. When you compare costs and outcomes directly - what spaceX delivered vs what it cost us against any other launch provider, the difference is astonishing.

But that's all business stuff. What spaceX has done that impresses me is the technical stuff. They developed a relatively inexpensive rocket engine with a 184/1 thrust to weight ratio. That's the best thrust to weight ever achieved by an orbital class engine, like by a lot. Before that, I believe the record was held by the F-1 engine that powered the Saturn-V and took us to the moon, it boasted a 94/1 ratio.

For their next major rocket engine spaceX developed the raptor, a full flow staged combustion engine, running on methane. Explaining why "full flow staged combustion" is impressive is probably outside the scope of this comment, but please believe me, this is a huge technical achievement and it provides some very real benefits. And running on methane is a good choice for reusability, it burns cleaner, and there's potential for producing it off earth.

And of course most importantly they changed the industry by landing rockets. That's not a small feat, some of their competitors called them foolish for wasting time even trying, the industry was very much not moving in the direction of reusability. Now that SpaceX has proven the viability and in fact the huge advantage of reusable rockets, there are many rockets being designed for this, from Rocket Lab, Arianespace, Stoke Space, Blue Origin, Relativity Space, eXpace (a hilariously named Chinese company), and probably many more; this is now the way the industry is going, that's a big deal.

It's my understanding that the idea of a dense asteroid belt (the kind Han Solo might try to hide in) is basically pure fiction, they don't exist. However... that is essentially exactly what some parts of a planetary ring system may look like up close. So perhaps Han could hide in a planetary ring.

Alright thanks, those are some good suggestions. And don't get me wrong, the nas does technically work, I can do whole drive images, just not the differential file-level backups. What I really wanted was to be able to restore a single file quickly and easily. That was the dream 🙄

I see, so the simplified/traditional specifically refers to the written characters. I appreciate all the extra context as well!

Ok, so I'm going to weigh in here because I have first-hand experience, but keep in mind I am a relative novice at self hosting.

I've been using a machine that has evolved over the years from primary gaming PC, to backup server, to Bitcoin rig, to Plex server, etc. Well I finally got tired of complex raid backup solutions and bought a 4 drive Synology nas. I figured I might as well just go with the name brand because I'd probably pay a bit more, but everything would work right away.

Everything did not work right away.

I fought so hard to get incremental backup working... So hard. But it just refuses to copy some files. It actually struggles with filenames! It can't handle names that have too many characters or use certain characters. (Filenames that Windows and the MacOS have no problem with). So if I want that backup to work, it appears I have to rename hundreds of files on that PC and hope nothing breaks... While their hardware seems fine, I am thoroughly unimpressed with Synology's software.

Ok, it's a bit off topic, but can I ask a naive question?

What the reasoning behind the different terminologies for the Chinese languages? Usually I see them then referred to as Mandarin and Cantonese, but sometimes I see the terms "simplified Chinese" and "traditional Chinese". Or have I totally misunderstood what those terms mean? (Entirely possible)

Please forgive my ignorance.

Kessler syndrome is no joke.

Except it kind of is.

It can't really happen at very low earth orbit, where the majority of satellites are, as any unpowered space junk would deorbit relatively quickly. And it can't really happen at geostationary orbit, where most of the rest of them are, because when you go out that far there's just so much space between every single object... The only way you run into something out there is on purpose and after a lot of calculations.

So there's medium orbits and higher LEO those are the only areas we need to be really careful with.

Hell yeah! Actual useful industrial endeavors are the way we finally get humans off the planet, this is the way to the future. Once there's a reason for industry in space, there's a reason for support industries, construction, material supply, fuel supply, maintenance, etc. With those support services comes reasons for people to start to actually live in space, where they work. And from there, we can start to spread our legs and really "move in" to solar system, and the story of the human race truly begins.

It's like the rings of Saturn: the likelihood of a collision is so remote that they didn't even consider it when we had a satellite move through it.

I didn't realize that, what mission is this your talking about? Cassini?

Oh I caught that, totally. But that doesn't change what it literally says... That shits funny!

Personally, I think it's annoying that this got down votes. It's short and dismissive, but it's correct. Sometimes it's just not worth longer answers.

Also, some arguments should be dismissed, just ask a judge.

Your account is concerning in that you present yourself as a fact checker, yet we have no idea what your motives are.

It's funny you should bring that up deceptichum...

Seriously, could your usernames possibly be more on the nose? This feels like a setup.

I feel like I should definitely ignore both of your posts and let the article speak for itself.

I guess this is something important to point out when saying something may drastically affect our lives.

Sure, so I mentioned it.

The scale of the effects and their expected outcomes are actually important

Look, I try to keep my comments brief whenever I can. Totally feel free to ask a followup question if you think I left something important out.

The questions I pose are to understand whether what is saying is actually a threat or just some scaremongering.

Well, only if it scares you 😉.

But seriously, I don't think It's really anything to worry about. It was pointed out that other forms of energy generation, like wind or tidal, or hydroelectric can have this same effect of slowing planetary rotation (Hydroelectric has actually had measurable effects on the rotational velocity, there were studies). Likewise, geothermal power accelerates core cooling (nominally). Which ultimately could also mean our demise. So we don't really have better options.

But all of this is so long term, none of it would matter for hundreds of thousands of generations of humans. And to be quite honest, I will assert right now that in hundreds of thousands of generations, the human race will have both different means of power generation and different planets to live on. (Or we won't still be around and it's all moot.)

So no, no reason for anyone to worry about this, maybe ever.

But I guess the takeaway I was trying to illustrate, is that we live on a habitable planet, but most planets only get these conditions for a short blip of time, we seem to have gotten it for a long blip, but it won't last. We need to figure out how to live in the more hostile environments of space and other planets without the magic conditions of earth if we truly want to survive past this blip, especially if we're shortening our time here by burning massive amounts of fossil fuels.
