Aren't we arguing about the wrong things here? The hyperloop is actually something worth having as it will get you from SF to LA in 30 mins. Even if it costs more and takes less people than HSR, it's still far better than HSR for actually getting you between the two cities in the kind of time people would like. If you could set up these 30 min hops between cities all over the world, you will improve humanity as a whole. That's something worth attempting.

If capacity becomes an issue, you could just add more tracks. If the cost is wrong (and it no doubt is), why is nobody coming up with the real cost so we can compare this properly? Hand waving about 'too low!' is only useful for arguing, not for finding a solution. Are there other ways that the cost could be brought down?
>Perhaps it was power that corrupted him or maybe it was his close advisors that stymied his original purer motives.

I think it's more likely that the Federal bureaucracy is simply more powerful than our elected officials, at least some ways. They provide a great deal of the information Congress and the President use to inform their worldviews and decisions, and probably have well developed methods of getting what they want from the two. The bureaucracy has a real advantage by simply having less turnover, more continuous time in the system, hence more institutional knowledge of how to work the system, than the average politician.

So? That's a state of our knowledge. When we learn more about cancer and find a way to treat the underlying causes, we will have actual cures: treatments which result in complete remission in >95% of cases.

This will happen. It may take the tools provided by molecular nanotechnology, and a generation of oncological research, but it will. To accept that cancer is special is irrational deathism.
There are no excuses. Facebook should expect that hackers with english as a second language (or not even that) will find bugs in the system and that they will not be able to communicate the way the Facebook team expects.

They should stop finding excuses and start to focus their efforts on making sure that people with no communication skills can report any bug.

Suggestion: Facebook could create a new "Facebook_security" system, which can be used to report bugs. The system would have the same production version, but the terms and conditions would be flexible. It would be used only for security purposes, and if someone finds a bug, they could record the exploit and send to the facebook team. By doing this, they would make sure that any type of bug could be reported.

I agree with your point but I disagree with your method.
I agree that they should also offer a means to communicate in other languages, if they have that capacity.

But, your choice of sentence structure - with clauses and formal social graces - would be hugely more difficult for a non-native speaker to parse correctly.

If the goal is to communicate with a non-native speaker, Facebook's message is appropriate for its clarity.

Bear in mind also that they probably do want incorrect bug reports to "go away" - unless Facebook apply infinite resources to this, some false negative errors are inevitable.

But terrorism induces terror and people don't want to live in terror. So either 1) we need to make a serious attempt to cause people not to care about it and acknowledge its a tiny risk 2) we need to stop terrorists or 3) we need to make people feel like we achieved 2.

None of those options are easy and I've never seen a real proposal to seriously attempt 1. Other than statistics, how would you go about it?
Rushkoff kicks butt, but his book can come off a little geeky and at times incendiary. In short, you'd kind of say: "hey, just back off and half of the things he is saying aren't issues," and yet most of the population is engaged and actively struggling with what he's talking about, despite how silly it might be.
1. I agree, Facebook probably could have been more tactful in their reply. Your example reply looks good.

2. That said...if you were the security researcher, and you received a "This is not a bug." - you would still be fully wrong in selling the exploit to the highest bidder. It's not ethical to do that just because you failed to get a bounty after reporting it, especially if you only tried once.

I think both sides should have done things differently. Hacker News is skewed towards BigCo hatred as a whole, and I think it's showing a bit. The majority is siding with Khalil despite the fact that there are valid reasons for him to not receive a bug bounty.
Facebook should give him a job. The current security team appears to need some help.

What about Ratchet? How is this different?
There may be some valid points in there, but I don't consider it very productive to get this kind of info from this source. I'm not sure what their agenda is, but it clearly doesn't have anything to do with economics or transportation. From the authors recent articles, I have my doubts he would approve of anything that isn't initiated by government. Consider this article http://greatergreaterwashington.org/post/19330/supreme-court...

Since I lack the expertise to know myself whether the numbers are plausible or will work out, I need to rely on the expertise of others. And one of my ways of evaluating the expertise of others is if they appear to be guided by facts or by an agenda.

In the engineering field, I've found there's an issue with a subset of engineers where they get some kind of enjoyment out of saying why something can't be done without providing any suggestions or improvements to make it possible. They just feel the need to be negative and list reasons why something won't work. It's unfortunately common, it's unproductive, and it really gets kind of annoying after a while.
> Yes, but it is exactly these kind of policies that let enterprises, corporations or organizations look bad.

And what do you propose the alternative? A legalised document that outlines every "if this"-"then that", in every language, continent, dialect, etc.? You know how that story goes...

> And denying some kid a few hundred bucks even so he found a legit hack just because he didn't follow some proper corporate policy guideline does definitely reflect negatively on Facebook.

You know what makes Facebook look even more negative? The future precedence set when good-will hackers think it's OK to use a non-test account and drop the exploit on the CEO's page.

I know it's hard for the HN community to do so, but let's try practicing some empathy with both sides before we pick up the pitchfork.

Refuse to be Terrorized (Bruce Schneier, 2006)

http://www.schneier.com/essay-124.html

The point of terrorism is to cause terror, sometimes to further a political goal and sometimes out of sheer hatred. The people terrorists kill are not the targets; they are collateral damage. And blowing up planes, trains, markets or buses is not the goal; those are just tactics.
The real targets of terrorism are the rest of us: the billions of us who are not killed but are terrorized because of the killing. The real point of terrorism is not the act itself, but our reaction to the act.
And we're doing exactly what the terrorists want. (...)

Our politicians help the terrorists every time they use fear as a campaign tactic. The press helps every time it writes scare stories about the plot and the threat. And if we're terrified, and we share that fear, we help. All of these actions intensify and repeat the terrorists' actions, and increase the effects of their terror.

And giving up your freedoms "because of the terrorism" is the worst thing imaginable.
Do you find the Oracle spatial solution superior?

Konami has the Pro Evolution series which was better than FIFA up until 3/4 years ago when EA completely changed the game mechanics.

I can't ever recall any European publishers making any hit football games, not sure why. You probably won't see any for a long time either such is EA and Konami's dominance

I actually haven't played any football games on a console in the last 6 years that haven't been either Konami or EA.

Bitcoins and Gambling: A Good or Bad Idea?
I waited and waited to find Postgres 9.2 with PostGIS(>=2.0). 9.1 was all that ever materialized. If you're happy with Postgres 9.1, you can do the soft upgrade mentioned in the post. You can also roll your own PostGIS if already are using 9.2. Strangely, Linux is the most annoying platform to install Postgres and PostGIS on. (usage wise, it's just fine) Uninstalling Postgres on Ubuntu can lead to some pretty significant troubles (the /etc/ artifacts remain... don't delete them!!! the distribution packages do NOT contain them)
What a lame nick.
It's not hard to reason yourself into that situation... part it is that as a software dev in a corporation, you have a "better" life than 99+% of humans currently alive, or who have ever lived. You are unfathomably lucky. To even be in a position to contemplate "Oh, this career isn't spiritually fulfilling enough" necessitates an unbelievable amount of privilege (not using the word with any negative connotation). We are having this discussion right now between a bunch of other incredibly lucky and privileged people. If we included an average spectrum of 100 people in this discussion, we would have 50 starving people begging for an apple, 40 McDonalds workers pulling extra shifts to pay for their food tonight, etc. and our complaints would be absolutely ridiculous. Our discussion here within the HN community is like people in the yacht club lamenting that their yacht is aging and isn't made from the most prestigious woods. That is the kind of perspective your favorite drug can impart...
that is insanely complicated, dude. i'd award you points for drawing attention to how complicated the current stack is for deploying something that should be relatively simple.

Even if he is right and the math does not add up, I do not think that Musk is likely go to all this trouble to try and boost Tesla sales in California in 2026, which is the earliest that HSR is planned to get anywhere close to connecting LA and San Francisco, and even then it actually only gets as far as San Jose, the San Francisco bit is scheduled to open in 2029.

I can't see a plan involving the idea that in 2029 Tesla would be so dependent on Californian sales rather than global, that it would seek to stop a local rail network from progressing. Especially a plan so convoluted as to involve actually taking time out from running a rocketship business, car company and solar power company, in order to design a rail network that according to the theory, you do not want built.

Not much. Most of the time it's easier to just use many simpler mechanisms and time and actuate/control them singly instead of these mechanisms. At least for the more complicated ones. Most of these (that I've seen haven't gone through them all yet) deal with turning one form of motion, circular or linear, into another with varying alterations, speed, period, or direction change, which was really important when all you had access too was a spinning power source, say a water wheel, and you have to convert that energy into every type of motion for your machine.

Hey now, there's nothing wrong with that. In fact, it's preferable. If you live in Jersey City, Hoboken, etc. you're on the Path. That means you're in the city in 10 minutes for minimal cost. Oh, you also pay less in taxes. How do you beat that?

If I were going to spend a ton of money on spatial solutions, I wouldn't give Oracle a cent. ESRI's SDE is my Spatial Database Extension of choice. It runs on top of Oracle, SQL Server, Postgres and DB2 (You know... if you're an AS/400 person)
I thought the whole idea behind whitehat reports was to keep these exploits off the hands of malicious hackers.

Whoever made the decision not to pay this guy should check with Mark Zuckerberg. If Mark is still adhering to "the hacker way" he should embrace such clever ways of reporting exploits and invite any whitehat to test them on his or better, {the idiot who decided not to pay}'s profile.

Hacking and finding exploits requires thinking outside the box, by imposing rules and "terms of service" on them, Facebook might be defeating the whole purpose of the whitehat program.

Any exploit violates Facebook's terms anyways. By not paying, Facebook is telling the whitehat community "go ahead, do our QA for us, we will only pay you if we feel like it"
You could replace "Obama" with pretty any other PM or president of any country on earth, mix around the current affairs to suit, and your comment would be just as true.

Welcome to media-driven representative democracy. And when I say "representative", I mean the media represents us, which it basically does. And when the media gets tired of a story, after a few days or weeks, they move onto something else, and so do we, and so do the politicians. That is their job, and that is what we expect from them, as voted by us through our support for the media, who represents us.

Democracy depends on scrutiny, accountability, long-term follow-up. It's a problem.
I recently had to create an extension for as many browsers as I could, which ended up being Chrome, Safari, and Firefox. The easiest - by far - of these platforms was Chrome.

The Safari distribution channel is a ghost town: http://extensions.apple.com/

Most Safari extension makers choose instead to just host the raw executable on their site, but that makes pushing updates a pain. See http://textbooksplease.com (visit in Safari).

Safari does, however, have a really nice extension builder which is useful if you don't know XML, I guess. And when you get down to the nuts and bolts (at least as far as I ventured), the Safari Extension API is pretty similar to Chrome's.

Firefox has been a royal pain. They have a "7-day review process" for all submitted extensions, and a tiered structure of reviews (preliminary and final) which translates to not being able to push updates for weeks at a time. Super frustrating when I can push changes to Chrome in about two minutes and know it will get pushed to everyone who already has it installed in a timely manner. I also found their API to be poorer documented than Chrome's.

I'm terrified of IE.
I think the author was referring to devices that can use html5, not that the site was made in html5. I could be mistaken though.
>The Hyperloop pods will travel[...] about 30 seconds apart in the tube. They will have a maximum deceleration of 0.5 gs [...] it will take a pod 68.4 seconds to come to a full stop.

>That's a pretty significant issue because safe vehicle operation means never getting closer to the vehicle ahead than the distance it will take you to stop. [...] That means that the minimum separation between pods is probably closer to 80 seconds or more.

Two flawed assumptions in here:

1. 0.5 g is the maximum deceleration under normal conditions (see p. 58 in Musk's PDF). Emergency braking would obviously be capable of more. The linear accelerators themselves are spec'd to be capable of 1g, and there's an onboard emergency braking system on top of that.

2. A vehicle that crashes doesn't stop immediately, but continues on its direction of motion due to inertia. That's why the two second rule is plenty safe on highways [1], even though expected vehicle stopping times are six seconds or more [2].

Furthermore, the article is basically an attack on maximum capacity, but that's not a real issue. The system is economically viable if it can get passengers from point A to point B at comfort and cost levels (including recouping investment) that compare favorably with other means of transportation; Musk cites $20 per ticket, which the article doesn't dispute Maximum capacity can always be expanded if the economics work otherwise.

I hear that a lot, but I'm curious who these masters are. And if you say "corporations" I'd like to know which ones you suspect.
Good points.

Urban dwellers - especially high-income ones who chose to live there (as opposed to people who were simply born into working class NYC or SF and stayed) - often have idealistic, maximizer notions of "taking advantage of everything the city has to offer". Which is impossible and absurd in even a medium sized city, let alone NYC, London, SF.
Being under control by Oracle is part of it's merits, and it counts massively negatively for a lot of us.
I think it's interesting how people are apparently compelled to bring up all possible objections, no matter how weak, when they really should be concentrating on the strongest ones.

For example, I think the discussions of headway at the beginning of this article are very good, and he lays out both problems and potential solutions, albeit ones that make the system less useful.

However, by the time we reach the end, we get crap like "Clearly he's unfamiliar with the Cypress Street Viaduct." Yes, I'm sure Elon Musk has never heard of that, sure. I'm sure he didn't research earthquakes at all when making his statement. Come on, really?

This kind of nonsense weakens the article considerably, because readers will tend to concentrate on the weakest aspects of it, not the strongest.
To be honest, it reads like a standard paid-for FUD piece.
In addition to those mentioned in other forks on this thread - There are also scheduling trade offs. One of the arguments against high speed rail is that it places a great degree of emphasis on end to end times, whereas on many routes there are a lot of intervening stops that will render greater capacity per train vastly more useful than higher speeds.

Probably not a concern for the given case - but if you're comparing transport options in an abstract sense it's something to be aware of.
> Putting your time and money behind groups like ORG (http://www.openrightsgroup.org/), the EFF (https://www.eff.org/), and Privacy International (https://www.privacyinternational.org/) feels more productive to me than playing an expensive system for a one-off political statement.

I agree that a one-off campaign in the 2015 general election is unlikely to bear much fruit. However, having said that, the Pirate Party's strategy of tackling these problems by being a political party and fighting elections is already bearing fruit.

For example, one reason the European Parliament decided not to go ahead with ACTA is that they fear it would give a major impetus to the Pirates, who the oldparties would rather not see getting bigger in the 2014 European election.

There is no reason, of course, why digital rights activists cannot do both -- political parties and campaigning organisations -- together.

Of course it's not delivering anybody from SF to LA as proposed; as proposed, with the putative cost of 6B, it will take you from Hayward to Sylmar in 35 minutes. Great, but the cost of getting from SF to Hayward or Sylmar to anyplace in the LA basin that anybody would want to go to are not included.
