Indeed, putting the old clues together with his new hints narrows it done quite precisely.

It will be a Ground Effect lifting body on an electromagnetic rail. The lift is provided by aerodynamic effects, and thrust is provided by electromagnetic force.

Based on the details of the design, it would be capable of supersonic speeds like the Concord, while employing Ground Effect like an air hockey table, and propelled like a Rail Gun.

The biggest challenges will be keeping the vehicle stable and at a constant distance from the power rail at high speeds, as aerodynamic disturbances can destabilize the vehicle. Given Elon's expertise with rockets, this should not be too difficult.

EDIT:

An prototype of a ground effect train:

Elon's will use electromagnetic propulsion instead of electric fans.

EDIT 2: I just realized this may be Elon's electric jet idea. He may use a ram-air electric jet at high speeds, and only use the power rail to get the vehicle to supersonic speeds where the ram-air engines are most efficient. This would make it MUCH cheaper than maglev by eliminating the power rail on the majority of the track.

EDIT 3: Rail gun diagram.

The walls of the guideway will likely house the propulsion system.
Oh very good sir. golf clap

Requoting that is ridiculous. Allow me to list why:

1. There is nothing for the parent poster to feel ashamed about. Nothing he said is shame worthy.

2. He wasn't aggressive. It wasn't a knee-jerk reaction. It wasn't unprofessional, rude or childish.

3. The author of the bug didn't make a mistake. They submitted a bug report designed to be as brutal and belittling as possible. They didn't just lose their temper in the heat of the moment, they decided to setup a new account under a pseudoname, then blasted the author of the software product.

4. Writing software is indeed a team effort, but as with any team if one party abuses the other the team rapidly becomes less effective.

5. Feedback doesn't have to be abusive. It's a bit rich to say on the one hand feedback can be abusive, but on the other hand that abusive feedback must be then taken in a "civilized manner". Do you not see the contradiction?

6. There's nothing "prudish" about remarking that abusive bug reports don't make the bug get fixed faster or better. To be a prude, you must be excessively concerned about propriety, and there's nothing in the parent's comment that is excessive.

7. The parent's comment was a general comment, and wasn't an attempt to fix the bug. There's nothing misplaced about the poster's priorities. He's here to comment on HN, and that is indeed what he's done.
>"This almost seems like just someone being contrarian for the sake of it."

Retorted a very angry person, disagreeing sharply with a short, lighthearted post written about how enjoyable latte is.

From the sounds of it, you're a bit out of touch with the common man these marketing lines are trying to reach. If they were trying to appeal to you, they would say, "hey you, come be super negative about other people's ideas! There's an endless selection of directors and producers to call stupid and childish!"

A few bucks a day still matters quite a bit to me. And I love latte. And I really liked the post.
Well that's the first good thing I heard about nicotine besides stress relief I guess. Never thought about it this way.

I think many people reading this get a sort of uncomfortable feeling thinking about 'white hat' security researchers receiving bounties for disclosure -- it sounds a bit like extortion, especially when people talk about "wondering how much more you can get elsewhere."

But at the same time, the reality is that we're in somewhat of a security crisis. Businesses responsible for the security and privacy of our personal information and identities are clearly not in fact capable of protecting those on their own. (In part because it is a very hard task). They need help. And they're not going to get enough help purely from unpaid volunteers.

In a more reasonable world, the government would have armies of 'white hat' hackers trying to find security holes (they surely do), and then _telling the effected about them_ (they definitely don't, they keep them instead for their own use). Because that would result in increased security for us all, isn't that in theory the mission of police agencies, increasing our security?

High Performance PHP with Static Typing
You know, that is a similar argument used by people to justify piracy; "I don't know if it's good, so why should I pay for it?"

And still they pirate it, watch or play it for free, and are entertained for X period of time. Or not, but even so, their time has been spent, and their money hasn't.

Even so, $2 isn't a huge loss if what you bought turns out to not have been worth it. And if you worry about the 40 minutes lost, then you need to learn to relax. Time wastage is not a bad thing per se.

Actually you can use a while loop, i couldn't figure out the syntax for a "for" loop but while works fine.
Unfortunately, I don't think that this is very useful. I am a novice Scala programmer, but I have quite a lot of C++ experience. I remember when I first tried to decode template errors - a single typo can cause multiple pages of hardly readable error messages. After a few weeks/months, you start to see what's behind the matrix and it becomes much easier to interpret those seemingly messed up errors. I believe the same is true for Scala.
Yeah.

There's a guy currently in solitary confinement serving time for felony hacking. The hack? Executing GETs against a public API. He got a 41-month sentence for that.

By any definition that's just crazy.
I think LIKE can use indexes where the left is anchored with enough text for an index to be useful. LIKE 'this is fun%' will be more likely than LIKE 'a%' LIKE '%fun vacation' won't but if you have an index on reverse(mycolumn) and you have where reverse(mycolumn) like reverse('%fun vacation'), it might.

You can also add pg_trgm as an extension and then create a GIN index. Not perfect at all but better than nothing.

Also indexes over expressions can be used to precalculate interesting sets if you have expensive routines in the database (the typical hypothetical example is image recognition).

2 pounds are extremely expensive for a cup of coffee. In Italy, where you don't usually sit down for an espresso it's about 25% of that or .6-1 euro (depending on the city and the area). OP is making the point that he doesn't pay for the coffee, but for the internet café.
I think it's likely this is not because of the prison as much as it is the laws which determine what crimes are punishable by prison sentences, and the people who enforce and judge on those laws.
Over the ocean? Would be relatively minor impact even for a catastrophic failure.

The thing is the speeds - anything that can do NYC-LA in minutes is going to have a catastrophic failure mode that kills everyone in a big radius. I am just trying to imagine the London Underground at 14,000 mph.
Yes, exactly. It would also be able to crawl linked pages, take screenshots of broken pages, show the path how to get to the broken pages, provide reports, ability to schedule checks like say every 24 hours, alerting (SMS, email), ...

Plus it would check not only links but also images, stylesheets, scripts, submitting forms - something like a 'website testing platform'.
What's the program selection screen?
Honestly I think my next monitor will have to be a 120Hz 4k screen.

I'm not sure I could take the step back down to 60Hz after getting used to it, for me it's a much bigger deal than resolution.
Nice, that will help me to forget the guilt of asking the guard a "proven" truth ;)
$4.5k is decent. Were you expecting to get rich? There are contests where you can rake in much larger amounts, and you could make a killing forming a penetration team if money is the issue.
The nature of America's prison system is driven by the fact that middle class white people vote for politicians and policies that put poor black people through a cruel, inhumane and all-too-usual system of torture and deprivation. Is unusual sadism a national characteristic? I do not want to think so, but the evidence suggests otherwise.
Yes but the problem is its low refresh rate. If you're looking at static images, I'm sure it will do great, but if you are trying to watch a movie, play a game, or do anything that has fast motion, you won't have a good time.

Not sure what they wanted to achieve with this article, as the article paints a picture different from the title.

2. In medium term likelihood of most extreme scenarios is less than what was expected.
(hey ho, extreme scenarios are not to account for, thats why they are extreme)
3. people should be exactly as concerned as before about what climate change is doing

What is the actual black market value of an exploit like this? Is it in the realm of $4,500?
The more I have to do, the more motivated I am. If I know I have a few tasks to do, but no actual appointments or deadlines, it's pretty hard to get out of the bed. I need stress to be productive.
Somewhat offtopic: I learned to program using a variant of BASIC on an 8 bit machine. While it was limited in what it could do, it also forced me to reinvent the wheel, which I think as a novice is a good thing. Once you understand how you would build something, you will have an easier time understanding how others would do it. Since then, I have always used the approach of "how would I do this?" To figure out a new paradigm.

For example, how would you create a simple memory allocator? How would you multiplex a single timer interrupt to perform all necessary OS services? How would you create a process scheduler? How would you implement a syscall handoff from your running process to the OS and get the result back? How would you implement something like inotify/kqueue? I play this game with every bit of technology I touch.

The fun begins when you come across something where you are way off base. You think you have a great idea for how to do it, and then you see an implementation that is much more clever and usually simpler than yours. That is when I think you grow the most as an engineer: after you can truly appreciate the genius of the accepted solution.
Wow, I feel that you missed the point.

Coffee gives a guaranteed positive experience - you know what you're getting - and the latte is not the only reason for that.

People are happy to pay for coffee even if there's a fair chance the coffee will be bad. If the service is good, and you get a relaxing place to sit and work, and you get a caffeine hit, that's usually more important than the product. Money spent on coffee is never wasted - you always get more value than the amount spent on the whole experience.

If you buy an app and it's bad - that's the end of your experience.

Even if your coffee is bad, you will likely get a refund or replacement, if you care to spend a second to ask.

If your app is bad - the money's gone and you have no recourse. You might be able to fight your way to a refund (but you probably will view it as sunk cost) and there's no way you'll get a better app as a replacement.

App developers who use the throw-away line "less than you spent on your morning coffee" need to be more aware of what they're comparing their experience to. Apps really don't compare well.

Just because prison population is rising does not mean that people are choosing to go to prison. The criminal justice system is choosing to send more and more people to prison for offenses that would not have incurred prison time in the past.

I don't think there exists a team of generalists. Every person has individual strengths and weaknesses. As a lead, i feel my main role is to identify what those strengths are, and play to them. I think his main problem though is, i can't tell if they even have a lead.
this is a big problem when you judge the climate of whole earth by just one number. "Mean surface temperature" it is called. Even in present article, the author clearly talks about this number being not as increasing as expected, but cautioned the increased uncertainty.

Which means, local variations will increase and that should increase worry not decrease.

Ubuntu error tracker
Canonical collect hundreds of thousands of error reports daily from millions of machines.
The market is huge (local businesses). They can sell (and deliver on their pitch) at a higher price point (~$130/month per user). Potential is tough, but it is reasonable to believe that, at the current rate, it could be generating $1M+/yr in a year or two. As far as resources, they are a small company, but have access to a sales force that is very inexpensive and can close on cold-calls, both in the US and internationally.

I believe they are looking to partner because they either can't afford, or don't want to pay upfront for development. They are non-technical for the most part and need consulting/advice in that regard.
Unfortunately or fortunately, I think much of the world would disagree with you and argue that such behaviour would be 'meddling' and gross overstepping by the government, right now.

Perhaps this sort of governmental 'help' would be possible in the future, but right now it seems that such behaviour would almost certainly result in cries that we had entered into a police state. :/

Coffee & cigarettes
I agree. A cruel and vengeful society breeds yet more cruelty and vengeance: The evident evil of the machinations of the state becomes a cancer that twists and sickens our collective conscience.
Understandable - but from what I understand, your givens aren't typically given.
I think it's tricky to assess. There's a lot of support for the idea of high black-market prices for drive-by clientside remote code execution. Those vulnerabilities have a long half-life (because of the latency of patching) and maximal value to attackers (collect zombies, snarf payment card information, &c). Neither is true of website vulnerabilities.

For a vulnerability that can be instantly eradicated, everywhere, as soon as the target finds out it exists? There might not be much of a market at all.

(I don't know).
Matt Gemmell Uses this
Exactly. And if you've been paying attention since the start of the game, instead of treating it like a codeacademy or similar programming challenge type, you've already picked up on a few clues that.. the government (and its minions, including EEM) don't really hold you in high esteem.

Musk has said that his idea of the hyperloop involves a system that "can never crash". Assuming that he's not just talking about really robust safety protocols and instead is referring to some inherent property of the system I think there's probably some missing detail here.

If the statement changes from true to false, then it wasn't true in the first place. If the statement was dependent on some other criteria, and those other criteria change, then the fact doesn't change as it was dependent on the criteria that changes.

e.g. My rooster crows in the morning.

I ate my rooster.

My rooster no longer crows in the morning.

The criteria is that the rooster must be alive. When the rooster is no longer alive, the above fact should have been stated as "My rooster crows in the morning while it is still alive".

> Elon Musk is the last big industrialist alive, after Jobs passing. If his endeavors succeed he'll be remembered alongside Edison, Franklin, Ford, Jobs etc. It's admirable.

I think you don't know enough about the world's industrialists. (And neither do I.) Most of them are less well known than Elon Musk. So just because you don't know them doesn't mean they don't exist. My guess is that China has quite a few people with grand ideas and capabilities.

> but with the role of "web developer," being divvied up into "front end developer," "UX designer," "graphic designer," and "backend developer," it does seem to me that specialization, not generalization, is the way we're going.

And yet someone has to 'glue together' the roles and understand what each specialist is doing. I feel that's where I, as a generalist, fit in. It's not Project Management per se, lead developer with oversight for the project?

I haven't figured it out yet - I like this role, but it's not hugely hireable :)
This will benefit Google in some ways for sure. In the corporate and enterprise environment, where updates - even critical security patches - must be thoroughly tested before deployment, this will put a burden on the IT staff to expedite this process. I'm betting some will tire of this and move to Google cloud services where they have to think far less about this kind of stuff.
