Whenever Richard Branson invest in something you know its basically a terrible idea.

This company adopted the Hyperloop because it allowed the to get funding based Musk name but then instantly went away from everything that Musk suggested would be needed to make the concept viable.

What Musk actually published can still be read here:

Musk really only thought Hyperloop made sense between two really very high density urban centers such as SF and LA. For the majority of transportation between cities super-sonic electric powered flight was his preferred solution.
None of the reasons that the current passenger rail system in the US is horrendous are technical. It's entirely feasible to build proper passenger rail networks with current, look at Japan and western Europe for some examples. The problems are all sociological in nature.
Holy! I've longn been interested in working on a side-project like this. How do you interface with the game? Do they have exposed APIs? I'd love to know more! Please give us some more details/Github/Bitbucket/blogposts!
That's cool, but it's only going to save the 1% that knows how to bend the internet to their will. What we need is legislation, like this: https://www.theregister.com/2022/01/31/website_fine_google_f...

That would actually make difference, not only for the HN crowd.
I wonder if the chaotic noise dominates social awareness because people are simply unaware of the macro trends influencing them, or the more charitable explanation that they are aware they exist but accept they are helpless to change them. Either way, this entire ordeal has basically solidified my position that as a society we are woefully unequipped to solve any of the major problems that threaten us.

People are so preoccupied with the audacity of x doing y that dominates the news cycle, but nobody seems to actually care why x is doing y. They just slap some shallow explanation like they are white supremacists, or they are mad George Floyd was killed because of police brutality and consider that level of understanding to be satisfactory while simultaneously being concerned about how increasingly divided, populist and radicalized western society is becoming.
Because the US government shovels hundreds of billions of dollars of subsidies every year into competitors of passenger rail?

Good review article. I always enjoy browsing the references, and found "Computer Age Statistical Inference" among them. Looks like a good read, with a pdf available online.

The large thermal coal producers in Australia eg Whitehaven or Yancoal probably have a nett negative worth at this moment. Yes, they are currently selling coal for a high price but that will not last more than 2-3 years. Then the mines are worthless and you have a huge clean up bill.

Using most DCF models the mines are worth nothing or less.
The companies that own the railways are in the business of making money, not in the business of screwing Amtrak.

I'm sure they would be more than happy to prioritize Amtrak trains over their cargo customers if they are suitably compensated for the trouble.

If Amtrak isn't willing or able to compensate them for it... Then clearly it's not that important.

After watching the video of a traffic jam inside the 1-lane wide tunnel, I'm not sure I would dare to go into it. I immediately thought what would happen if a car crashed into the wall and it caught fire. Seemingly, it didn't have enough space to go around it.
Yeah it was amazing living in France where rail is often faster, and sometimes much faster than driving. And often quicker than air travel when going from city centre to city centre.
Yep. I do X-Y charts like this https://www.dahosek.com/wp-content/uploads/2021/10/NewImage-... with Excel and Numbers doesn't correctly handle gaps in the date sequence or duplicated dates for the vertical lines (unless they've fixed this since I last checked) so I still keep Office around for that and a few other minor UI affordances that I prefer in Word.
It's a case where not having something like the old-school hierarchical Windows Start Menu with its delightful "accessories" section, is unfortunate.

So the police weren’t doing their jobs.

This is especially insane because you can no longer distinguish between “protestors legally protesting” and “protestors illegally blocking critical infrastructure.”

That is very much the government being stupid.
I am not working on anything specific but I have three ideas around a interesting alternative for google maps/yelp, a dating app that addresses the unbalanced experience of men/women, and a crypto idea that helps reduce your chances of your funds getting seized by the likes of the Canadian govt.

> Even without that legislation, most people would already care about avoiding poisoned food.

There is lots of evidence that people would still use harmful substances when it’s nice and cheap. Then other people would be exposed to it just because it is impossible to know the chemical composition of everything around you. Lots of people care about avoiding things like toxic chemicals and harmful bacteria, the trouble is that they cannot see them.

> So a law specifically forbidding poisons is in line with what the majority already cares about.

So why not do it, then, if it is the right thing and people want it?

In the real world, people are not perfectly informed, and fraudsters are willing to lie. So law and enforcement are absolutely necessary to end harmful practices.
See lead paint, but also leaded petrol, asbestos, antibiotics in farm animals, and insecticide chemicals spread willy nilly across the countryside. These things not just disappear on their own because some people don’t like it.

Even on the topic at hand, to be honest. People know that ads and tracking are bad and annoying, even if they do not see clearly the extent of the damage. Some of us know how to avoid most of them. And yet, they keep making more and more money, and are far from disappearing. It is difficult to take your point seriously.
None. I never really understood the logic of thinking you can escape Earth's problems by going to Mars. If travel is easy enough to sustain life there, it's easy enough to bring anyone's problem up there as well.

That would be true if US passenger rail was actually capable of high speeds to start with.

As it stands right now US passenger rail is total joke compared to the rest of the developed world. Slower, less reliable, more expensive. Air resistance in the US is the same as everywhere else, so that isn’t the limit factor.

Worth noting that this was basically what Jobs offered developers initially and everyone hated it.
Because all the US passenger rail companies went out of business. Amtrak was essentially created out of the wreckage to maintain some passenger rail service. (It's a very complicated history.)

Amtrak makes almost all of its money on the Northeast Corridor which it then basically throws away in the rest of the country.
That is just one of the limits. At the speeds hyperloop was proposed to go, you need really wide curves to limit g-forces on the passengers. Not just when going left or right, but also up and down. It would be an absolute nightmare to get all the right-of-way done, and even then you would need immense amounts of earthworks to start curving uphill miles before the hill actually starts.

I think that you make a fair point, tbh. Its easy to think that shouting is clearly defined, but we OPERATE IN AN ENVIRONMENT where people will think that I just shouted four words.

One persons shouting can be another person's virtually normal tone but in a more tense discussion.
It wasn't a vision of mass anything, except maybe delusion. The nameplate capacity of hyperloop between SF and LA was 840 passengers per hour, which is basically zero. Whatever hyperloop was, it was never "mass transit".
i honestly can’t say i see the usefulness in your UI diagram. The issue is that you’re basically displaying all of the code so it’s just redundant. You need to make it higher-level, e.g. add an annotation which you can apply to specific methods and fields and constructors, and then only show nodes in the diagram when they have that annotation.

Another case where a UI view would be especially useful, is live interactive UI/UX previews. Whether that be HTML or Java Swing GUI. The left window is code to render a part of your application’s UI, and the right window is an interactive preview of the UI itself. You can resize the preview, change attributes like color, and maybe add components, and it will affect the code. Or a game engine where the “scene” is actually constructed by code that you can edit, and it will edit the scene.

People are jumping to conclusions that this was some sort of criminal enterprise. The article makes no claims of criminal activity. There are clearly fibs - none though that are particularly unique in the design agency world. Perhaps there is some actual criminal fraud here, but the case is not laid out specifically.

The fact is all these "jobfished" people signed up willingly for a job that was purely commission-based, and had the agency actually been able to attract a paying client in the first six months, who is to say Ali wouldn't have made good on his promises to hire people on salary, etc.?

I know I'm going to be downvoted for this comment, but I wanted to lay out a contrarian point of view that doesn't just immediately jump on the bandwagon of the current Anna Sorokin/Tinder Swindler zeitgeist.
+1. We "might" need what crypto was supposed to do (and even then arguably not). But we don't need what it is: a bloated worthless commodities ponzi scheme.

Furthermore, its been shown governments can track all transactions. Without warrants (since it isn't money). Even for privacy focused funds. I doubt it would be hard for them to freeze account withdrawal and seriously hurt people trying to circumvent the law with crypto.

I'm very excited for the stuff I'm working on, as well as what's coming in general.
The original Hyperloop system is designed to not require a vacuum as strong as other vacuum systems of the past.

> Another extreme is the approach, advocated by Rand and ET3, of drawing a
hard or near hard vacuum in the tube and then using an electromagnetic
suspension. The problem with this approach is that it is incredibly hard to
maintain a near vacuum in a room, let alone 700 miles (round trip) of large
tube with dozens of station gateways and thousands of pods entering and
exiting every day.

> All it takes is one leaky seal or a small crack somewhere in
the hundreds of miles of tube and the whole system stops working.
However, a low pressure (vs. almost no pressure) system set to a level where
standard commercial pumps could easily overcome an air leak and the
transport pods could handle variable air density would be inherently robust.
Unfortunately, this means that there is a non-trivial amount of air in the tube
and leads us straight into another problem.
If the drones localize, you can get a constantly updating position over radio. Even with other tools, this will help disambiguate.

There are a few different parts here from robotics that can help.

- Tracking allows you find a how a patch of pixels move. Look up "klt" and "SIFT features". Older
- Recognition allows you to find a given object. Look up "yolo". Newer
- Motion modeling allows you to predict where something should be, and can include the transponder ego data. Look up "kalman filter"
- All three of the above should be available in existing libraries
- If possible, engineer the environment, like putting easy to spot LED patterns on the drones. This is always the easiest

A lot of people seem to be confused. Elon does not have any companies working on a hyperloop. He kicked off the idea and released a white paper with some very early engineering work seemingly put together by a group of engineers working at SpaceX and Tesla[1]. He never had any plans to commercialize it himself and was releasing it as "open source" for anyone else to take up.

Several companies sprang up to pursue the concept[2]. This article is about Richard Branson's Virgin Hyperloop which itself has a very checkered past[3] and has felt pretty scamming since the beginning, long before Branson acquired the company. Not sure if the acquisition by Branson has caused them to clean up their act or what.

The only Hyperloop thing that Elon or his companies seem to do is hold a design competition for students where they compete on a short hyperloop test track at SpaceX's Hawthorn facility. If I had to guess I'd say that this is most likely a recruiting tool for SpaceX.

Yes and no.

Yes, because they no longer plan to use the original design proposed by Musk (pods in vacuum in tubes installed on the ground).

No because long term they still plan to do hyper loop but the latest iteration of the idea is electric cars driving really fast in under-pressurized underground tunnel.

See https://www.boringcompany.com/hyperloop

That being said, Boring Company is still in very early stages.

They made significant progress (built Las Vegas tunnel and are in building more of it; created prufrock-1 i.e. v1 of boring machine designed by Boring Company).

The hyperloop is something they want to do and most likely can do. The limiting factor is more permitting and politics (for example: they had a deal to do a long tunnel in Chicago with one mayor and then the next mayor said it's stupid and scrapped it).
I'm not glossing over anything. If passenger travel was more profitable or even less profitable but easier, than all of the private companies would be in the passenger business.

Here we see a company that will end up building its own infrastructure deciding cargo is a better business opportunity than passenger. I think there was a certain amount of inevitability given the economics.
They are also interested in drilling tunnels on the moon and Mars for habitation.
The only reason crypto exists is because others needs don't match yours.

The desire and *idea* behind crypto is reasonable. It's just that the implementation falls way short of the idea.
When a conversation starts with accusations of "martial law," you don't get to wiggle out of that by wringing over "semantics": "martial law" means something specific, and using it in the first place belies either an incorrect understanding or a dishonest attempt to portray the Canadian government's actions in terms that nobody can disagree with.

> The ability for a government to unilaterally lock people out of their bank accounts without a court order or any form of recourse is virtually unprecedented in Western society.

No, it isn't. The US uses SARs[1] on a daily basis, and has since the passing of the Bank Secrecy Act in the 1970s. There is virtually no recourse to a SAR levied against your account: virtually every bank in the US will simply close your account and refuse to disclose any further information.
