Tesla /is/ investing in public transportation. From the Tesla Master Plan Part Deux[1]:

"In addition to consumer vehicles,... high passenger-density urban transport... in the early stages of development at Tesla and should be ready for unveiling next year. With the advent of autonomy, it will probably make sense to shrink the size of buses and transition the role of bus driver to that of fleet manager... It would also take people all the way to their destination. Fixed summon buttons at existing bus stops would serve those who don't have a phone. Design accommodates wheelchairs, strollers and bikes."

> I'd like to see more details about edge case scenarios.

The thing is, we're all MUCH more comfortable with the danger we're familiar with, than the danger we're unfamiliar with. Imagine if planes were just being introduced today - what are the edge case scenarios? What happens if there's mechanical failure at 30,000 feet? What happens if there's turbulence, lightning, birds, volcanic ash? What happens if the pilot is suicidal? What happens if... But we really don't care, do we? Air transport is familiar.

I'm not saying the dangers of new tech aren't important - they're very important; but keep in mind that while the idea of suffocating after a crash or malfunction in a hyperloop tube/tunnel will feel significantly more perilous than any misfortune that may befall you on a plane simply because a plane's risks are now familiar.

When we look back at how planes came of age, it seems like people were idiots to get on them (I recently read about the de Havilland Comet... it disintegrated in mid-air like 3 times in a year - don't quote me on that, but it was bad). Did it have to be so bad? No; of course some disasters could have been avoided with better oversight and accountability, but nonetheless, in the face of risk, the new tech provided such great advantages that its risks were accepted.
It's fair to be aware of the way new tech can fail, but we shouldn't dismiss a tech simply because it can't "prevent human error" 100% of the time, or be perfectly immune to failure of any sort.

If we can introduce a new tech that has failure properties similar or better to current tech, but that adds significant value to everyday life, we're netting a very positive gain. We shouldn't let fear any failure prevent us from pursuing new tech, just like we shouldn't let fear of stubbing our toes prevent us from walking.

Are you asking this as a moral question or a technical/value question? For moral, I can't help you. For technical/value, new Hyundais/Kias are generally regarded as very decent cars.

>If so, does this happen in Japan too?

Japan also has a VERY hierarchical management system, where top-down direction is the only way things are done.

One generally does not, because generally speaking none of these things have a first order effect on the product.
I've never actually seen anyone use vim more efficiently than the average programmer can use Sublime Text or Atom with no skill and a mouse pointer. It's just too much required engagement to do things as simple as move to a specific point on the screen or uncomment/indent a bunch of lines of code. Installing plugins is tedious, tabs/buffers/windows are clunky, and memorizing key commands for plugins (like a file tree view) is required before using it, not gradually learned using context menus as a crutch.
This is FANTASTIC! It's important to understand how massive the Earth is (even though it's a pinprick when compared to the sun). You can EASILY go 3-D or deep.

The deepest mines in the world are around 12,000 feet deep. This is about 6x the height of the tallest building in the world (2000 feet tall).

Imagine, thus, putting in a tunnel at what would be every 5th floor of a skyscraper and that you could fit 6 skyscrapers underground...that allows for approximately 150 stacked tunnels! Excessive of course but possible!
It doesn't seem reasonable to me. Increased pressure would normally come from greater food intake, which should decrease the amount of the hunger hormone. Is this pure speculation, or is there something in the study to back it up?
This is an investment in public transport. How could it possibly be construed as anything else?

I think a big problem is that when a powerful politician calls a security expert to provide an opinion, the expert might feel pressured into giving a binary answer, even if the best answer is "I don't know," or "not enough information."

Ultimately the root problem is politicians/media/people demanding certainty from experts who are used to dealing in probabilities.

Security is inherently a cat and mouse game. Nothing is ever certain. It's frustrating to see these stories play out in the media, and it's unfortunate how many people are so willingly uninformed. But I digress.
Hahaha. I came here to post this. The intro to Flashback (same team) uses a similar strategy and I think is maybe even a little more impressive.

Interesting. Based on a quick wiki (and thus a poorly understood speed read) ghrelin triggers growth hormone release. So if I were to combine carbonated water (no sugar or sugar substitutes) with a healthy diet, would it enhance the positive effects, i.e. muscle growth or tissue repair?
It's incredibly common. A live-in caretaker/helper in Hong Kong is about $500 USD/month. In South East Asia, it's a fraction of that.

I think you're reading far too much into my comment — of course it's deeply disturbing and troubling that this woman was a slave. I was not suggesting at all that calling her "Lola" in any way mitigates the horror of that. I'm only stating that in standard usage, that is what the word means in Filipino.
My wife and I found ourselves in this situation, and it there are slot of side benefits.

- We don't spend our weekends shopping.

- my wife can volunteer at my sons school and church, which opens up more social opportunities and keeps us tight with school.

- We spend less in clothes, groceries and eating out. The value of this is much greater than anticipated.

Overall, life is better. We're not driving new cars anymore. Other than that, the sacrifice is minimal. Her skill set is such that she can basically become employed again at any time.

My wife has always had traditionally-feminine work preferences, but she's felt a lot of shame from her more left-leaning friends and coworkers (we're both moderate liberals). Similarly, my office is very liberal, and I often feel a bit judged if I mention that my wife cooked my lunch or otherwise mention that my wife's hobbies are traditionally feminine. Ironically, our conservative friends and family have never said a word about whether she works or tends home; they're very laissez-faire about the matter. I don't mean to make a political point here; just an observation I found interesting in light of popular political stereotypes.

Consider an analogy to the 'reality' of right/left orientation. We stand on opposite sides of a table, and I say "There's a cup on the right" and you say "There's a cup on the left". Who's right?

Well, there's not really a deep disagreement because facts about left/right are observer-relative. Furthermore, we might reasonably conclude that left/right orientation isn't part of the fundamental structure of the world.

Now, if I looked at a timeline of events and said "Trump became president after Obama" and you (or any other observer from any other point in time) said "Trump became president before Obama", who is right?

Barbour is saying that this disagreement is like the left/right dispute. Maudlin is saying that it isn't.

I think it's fair to characterize this disagreement as being about whether time is really part of the fundamental structure of the world. And it's clear that there's a meaningful disagreement here.

Judge Alsup blocked Levandowski from working on LIDAR, which is just one component, he's free to work on the rest. I'm sure this isn't the ruling Waymo was hoping for, it's little more than a speed bump for Uber, there's other LIDAR suppliers out there.

I got the smackdown pretty hard here on HN for suggesting Waymo's case wasn't as strong as it looked when they first presented their evidence, but it isn't over yet, the Feds may do a criminal investigation and they may yet find something worth prosecuting over.
Very good advise, apart from the "rather than".

Without understanding edge case scenarios, we cannot make claims like these. Maybe these tunnels really will be more perilous than planes. Or maybe not. The whole point of asking the 'what if' questions is to clarify these issues.

Airplanes have been studied intensely enough that we know the rates and modes of failure. It's worth pondering the same for new technologies as well.
Ever know a farm family?

I worked on a farm in high school. The wife drove a school bus and was like your grandmother. But... she ran the books, ran the pipeline of hard working students for summer labor, could throw 50lb hay bales when necessary and change a tractor clutch in a field with an just a wrench and a hammer.
Soviet-block countries, especially USSR itself, were actually rather socially conservative, at least from Stalin on. Traditional gender roles in general, and as they pertain to nuclear family, were part of their internal propaganda.

This IS public transit. Public transit without the last mile (or in LA, the last 5 miles) problem. This freedom-supporting tech also thwarts the tyranny inherent in public transit (schedules, robbing your life with all the waiting, limited load carrying capacity, forced interactions with antisocial individuals, etc.)
Rabble was the first Eng hire at Odeo, the podcasting startup founded by Noah Glass and Evan Williams. When Odeo didn't gain enough traction and they were figuring out what to do next, a small Odeo team (which included Jack) prototyped Twttr. And the rest is history.
No clue why this is downvoted, these are valid concerns.

Measuring and avoiding ground settlement consumes an enormous amount of engineering and contracting resources in every urban tunneling job.

Flooding too can lead to work stoppages or long delays. You should have seen the Queens Bored Tunnels and Structures Project after Hurricane Sandy. It was pretty soupy.

The general premise is that electrons would remain trapped in their shells, bound to protons, even in the cold dark. At the subatomic level, the system is still in motion, even if the temperature of the atoms themselves is zero. Even if they are stable, crystalized common elements, in a static molecular arrangement, uadulterated by decaying isotopes.

Within the nucleus and among the electrons, a system would still exchange energy, even if there were no low energy photon emissions. Photons would still be in play between the electrons and the nucleus.

Within the individual subatomic particles themselves, there is also activity. As far as we know protons don't decay, but it doesn't mean they are without events, even when no one is looking.

Mostly I'm just trying to poke holes in the concepts and analogies that get bandied about, because when one attempts to apply common-sense, folksy wisdom to these topics, understanding frequently goes wildly off the mark.
Show HN: TOTP Based Port Knocking -- two factor firewall
Author here. Just wanted to get some feedback on this. It's a simple proof of concept, not meant for production code. I found several similar techniques, but none exactly the same.

Short version:

Client and server share a key.

Each can generate a TOTP based hash.

Client sends hash to server listening on UDP.

If hashes match the server opens the normally closed ssh port for a few seconds (long enough to make a connection).

Like a Google Authenticator TOTP code, the correct hash changes every T seconds so identification of the UDP port and interception of the key is only helpful for a limited (if any) amount of time.

Is this worth turning into a robust daemon? Is there a better way to deal with constant ssh probing? A module in a firewall would be ideal. Environment based config would make it fairly easy to use in provisioning for ssh admin with a smaller scan footprint.
Not a question. But I just wanted to say that this sort of thing is amazing to me.

I literally:

1. Saw this article headline about a polygon rendering engine on the Mega Drive

2. Thought, oh this is going to be good

3. Made some tea

4. Settled in to enjoy it.

Not only did I love the demo and your article, you cleared up a longstanding mystery to me. I know that Another World (aka Out of This World) and Flashback (intro only) used similar techniques to render "canned" or "pre-baked" polygon animations on the Mega Drive, but I knew literally nothing about how that was possible. Thanks to you, now I have some kind of idea. Were you inspired by those games, to pull off this awesome effect in your demo? (BTW, you achieved a much better frame rate AND did it without borders... totally badass)

Last but not least, thank you for the inspiration. I'm not a graphics programmer but I am a programmer and I have always been inspired by demos ever since the days of Future Crew. Coders like you inspire coders like me to better ourselves and be unafraid of challenges.
That's among the safest places to be. There's a whole section about it if you read the article linked at the top of the page.
>Even if the car's were relatively crammed close together in the tunnel, I can't imagine it would be anywhere near the density you could fit on subway trains.

Indeed. The problem always fundamentally reduces to geometry, and the only way to solve it is to increase density.

People always say, "we can just build more tunnels", but you'll just end up with congestion at interchange and entry/exit points, just like on freeways today. And the more tunnels you build, the more it takes for the operating company to recoup the costs, meaning higher fares to use the tunnels.

Best case scenario, this company reduces the cost of developing rail transit. Likely scenario, we just get the same awful freeway situation but below. Worst-case scenario is the unfortunate situation you described.
I somewhat agree, however in I don't think the parent should have been down voted. If someone doesn't regularly follow tech news then it is completely reasonable for them to have never heard of any of these incidents. In addition, the original comment was ambiguously worded as to whether he/she was talking about Netflix or acts done at other companies.
Nonsense. NeXT had largely failed in the marketplace. The best the NeXT people could do without Steve at the helm was Rhapsody, which Steve hated. And Jony Ive worked for Apple, not NeXT.

I'm rather surprised that "are you boring yet?" isn't in the FAQ.
No, it doesn't. If it did, buildings in NYC would be falling down left and right. Heck, I hear they even put them under entire bodies of water!

Yes, tunnels can flood, if they are below the water table. Good pumps can fix that problem. Again, the Chunnel being Exhibit A - it hasn't flooded, yet.

San Francisco's new Central Subway drilled two bores at a cost of about 150M/mi. What makes these projects insanely expensive is not the tunnel, it's the stations.
Thank you for the agreement. It's worth it to me to keep writing these things. My ideas aren't perfect, and I understand that.

But there are good reasons to keep telling people that this is a reasonable way to do things.

It's clearly not the only way to do things, but I'm tired of this idea that it's an awful, terrible way to do things.

There are way to do this that don't suck, and there are legitimate benefits.

It's not always the best way to do things.

But I often feel like we're dealing with people who haven't properly considered the options when we get into thee kinds of threads.
Same here. It was super obvious to us too when we had been living together for 24 years and had 5 kids.

Not too obvious by year 23, but mos def by 24!
An engineering study of ground subsidence and how to avoid it, vs "the building falling down" are two very different things.
"This is not a new concept, as buildings have been constructed from Earth for thousands of years including, according to recent evidence, the Pyramids."

Classic Musk snark. Love it.
I'm more interested in the nuances of tunneling, like how they'll handle water seepage and flooding. Flooding is actually a huge problem with climate change causing larger and more frequent major weather events.

After Hurricane Sandy, it took almost a week to reopen the subway tunnels.

I can just imagine the kind of kinetic force that'll occur if a sled carrying a car slams into a section that has a few feet of water.

Airflow and humidity are other concerns. Airflow is necessary to keep passengers safe. Controlling humidity is important for keeping the infrastructure from degrading more quickly.

Any good paints or fabrics or metamaterials that could be used as a tunnel liner that only allow water to wick in one direction (from tunnel internals to surrounding soil)?
