Yes, and all the other. But the fact that the USA is taking some responsibility anyway makes the orange baby with the weird hair look even more stupid.
Exactly you see this is a 2 for one stupidity. Firstly leaks don't cause shockwaves in tubes unless the tube is a perfectly friction free system and the leak is an instantaneous opening of the end (e.g. catastrophic explosion, not a "leak").
And even if it did create a shockwave, it's nothing that any proper aerodynamic system can't be designed to handle.
Statistics stack, as do reasons for doing something. This by itself is no reason for concern, however it is just yet another thing in a list of reasons why we should be moving away from the ICE.
Just because there are children starving to death in Africa doesn't mean I'm not going to solve my personal hunger issue at dinner time.
Oh except for the VW executive who was arrested at the airport while on holiday and has been stuck in jail for the past 1/3rd of the year.
And the 5 other senior executives who also have been had criminal cases brought against them, though currently they are in Germany so if the USA wants to do something it will have to be via extradition.
What is this McDonalds you speak of? When I travel out of country I often find myself at least 100 miles away from the closest golden arches and most restaurants don't offer free wifi. I went 2 years without seeing a single McDonalds.
Don't be daft, it was an example. I assume you go to places where you eat right? It doesn't need to be McDonalds (although that is almost universal). WiFi is available at nearly every little craphole village restaurant in the jungle these days. Short of trekking through the Amazon by foot it's actually difficult to find WiFi free places these days. Sure the very occasional personal will achieve that, usually taking a holiday specifically to get as far away from everything as possible, but in general the topic at hand (losing backups while on holidays) doesn't need to affect even a rounding error of the population.
My thoughts were more along the line if you could identify your phone via wifi or using a prepaid SIM.
Yes, that was my point. Your phone ID is not tied to your network. Regardless of where you roam, with what sim card, on what network the phone still identifies the same way to apps and to online services,... even if you didn't have a google account tied to the phone.
Then it should be obvious why it is not an ideal solution.
But it's not obvious. It amazing the number of times I've had to explain this to people in various contexts, including at astronomy conventions where people in general should know better.
We in Slashdot can complete this FMEA in minutes without any fancy degrees and show how nonviable this really is.
Also we have no idea how to get to the moon, planes fly in the sky based on magic, and bridges stay up through hopes and dreams. We don't need engineers, that's just another government lie to play with the employment figures and cause more student debt to pile up.
This is the one bit of physics he actually gets right. Exam physics that is. The kind that starts a question with "Assuming a lossless system with no friction...."
What exactly do you mean small leak? Air fills the vacuum at the speed of sound.
Jesus the GP wasn't joking when he said luddite nut-jobs who seem to purposefully ignore physics. Here's a tip: The speed of air moving in a vacuum has nothing to do with leak size. The air will rush in at that speed of sound, if and ONLY IF you suddenly remove an entire section of the hyperloop. Even then it will only do that speed at the entry nozel due to this thing called friction.
A wall of air hitting you at that speed would likely kill you. Face it, hyperloop is trash.
A problem we solved in 1961 when we first travelled against air at speeds faster than the speed of sound.
Hatch doors... which would be separate failure points along the way for the pressure difference to be changed.
Oh calamity, how would someone contain the whopping 14.7psi differential.
you've 14.7 lbs of pressure per square inch trying to keep that door closed
Do you? Ever noticed that the pressure inside an airplane is higher than that outside while cruising, yet you have all that pressure *preventing* you from opening the door on the inside?
This also aside from all of the issues related to thermal expansion & contraction of the materials, making the sealing even more difficult.
Vacuum expansion breakers are a thing. Not a new thing. Not even a fancy thing.
Best to let the trained engineers solve the engineering problems.
any failure causes its occupants to get exploded out the end somewhere
Cool. Physics! Assume friction free surfaces, inertia free occupants, ignore many years of aerodynamics engineering, add to it some bizarre theories of incompetence such as that a system will be designed without any breaks, and you have your human canon.
I was at the circus last week. Clearly all we need is a big net to catch the people.
You're right, it's 14.50362874 psi, not the 14.5038 psi the GP mentioned.
You can expect... fuck all damage. Guess what, industry is just as full of low pressure systems as it is high pressure systems, and as experience shows they just keep on humming even when they leak like a sieve.
Why not? I would think that even if my hand was paralyzed or amputated I could
If your hand was amputated, sure. If it was paralyzed, unlikely. They are measuring the signals down close to the appendages. If they got there in the first place you're unlikely to be paralised.
If this worked on the source (brain), or on the spine then it may be different. But the people who need this most won't benefit from this design.
go so far as to say that slowly, over time, people that are stupid enough to answer the phone at the wrong time will get themselves killed
I don't understand what you mean here. Specifically the "slowly over time" bit. It seems like every idiot on the road feels the moment they unpack their first phone they need to instagram themselves from behind the vehicle.

Fusion Drives are a PERFORMANCE-centric improvement, NOT a "Cost-Savings Measure".
You know what performs even better? SSDs. But they are expensive.
So suck it, moron.
If you ever finish sucking the Apple cock, maybe someone else could have a go.
Well yes... I'm sorry were you trying to say something? Was I praising VW? I assure you they still make shit cars.
Yes, and all the other. But the fact that the USA is taking some responsibility anyway makes the orange baby with the weird hair look even more stupid.

To be fair, Volkswagen's diesels are on average the cleanest on the market and have been for some time.
For a given definition of shilling yeah I'm sure they are.
You do smell the obNOxious smell of NO2.
No, because if you can smell NOx it then you're failing the 10+ year old emission standards, ... by a large margin.
Many sites don't need https since there's not much to protect in the communication when people just look at memes and pictures of cats.

Don't let that ruin your narrative though.

Oh wow. The only thing worse than ripping out an emergency system is leaving it in place when it doesn't work!
If your system is compromised in any way, the only sane response is to wipe the disk(s),
Wipe the disks? Are you nuts. I say we take off and nuke the entire site from orbit. It's the only way to be sure!
Pffft "engineerins".

Vacuum expansion joints are a thing. In those scenarios that awesome* force of vacuum gets contained by .... a small flexible polymer.

Context matters.

I don't understand what you mean here. Specifically the "slowly over time" bit. It seems like every idiot on the road feels the moment they unpack their first phone they need to instagram themselves from behind the vehicle.
And in Berlin if you call an Uber a taxi comes and picks you up.
I learned how to read between the lines, and see the context that the author themselves missed.
So you're reading something that wasn't said and replying to something the author didn't say.
so many people typically just blurt here and fail to consider the import of the things they're talking about.
You don't say!
