Why not both? A password entry system that logs in to a full-privilege profile when the user is in a geofenced location, and that drops to a more limited user profile if the correct password is used outside of the set location. As far as the user is concerned they still just need to enter a password as usual, but the system is more robust due to the additional test.

Further to that, the system could do things like immediately locking the user out if the wrong password is used outside of the geofence, and "Forgotten password" features could be disabled too.

I'd be amazed if this sort of thing hasn't already been implemented in existing security software.
1) Musk states specifically it is an alpha issue and welcomes constructive criticism

2) I did not claim Levy is a transportation engineer

3) Musk did this quite handy, he did not propose the hyperloop in a vacuum (pun intended) but for a specific application, this increases the chances of something being done with it

You have to start somewhere, think of this as a first proposal that can be suitably amended or scrapped in its entirety as more insight is gained.

I'm pretty skeptical about the whole thing but Musk has a history of pulling off impressive feats and I would not put it past him to come up with something that might work when tweaked. So let's hear it for constructive criticism (fix what is broken or provide actual proof why it can not work) rather than outright dismissal.
There are plenty of examples of over population in the world, but the US is not one of them. Our growth is slowing and there are huge amounts of available land. The country could easily be several times its size in population.

Yeah, it's not surprising that any change would make it faster. Plot twist: OP was previously typing the server response BY HAND.
IMO, browser plugins were the way forward. You can have all the fancy stuff that modern computers can do, like Google Maps or even Quake Live, and at the same time most of the web can stay simple.
If they had actually built the full run, it would have been cheaper. I would expect updated electronics over the life of the F-22 just as the F-15 and F-16 have been upgraded. Although they have done some pretty impressive things with those 1990's electronics. Embedded systems are a very different bird.
I think the distinction between providing aid to the FBI (or whoever) for a specific, targeted warrant but telling them to fly a kite when they want access to everyone without reasonable cause is perfectly reasonable from his perspective.
I agree with Voidlogic here. Perhaps his tone was a little confrontational, but his intentions were good. :)

Go 1.1 > Go 1.0.2
wrk > ab

In particular, ab should be avoided whenever possible. Apache Bench (ab) remains a single-threaded tool, meaning that for high-performance servers in particular, your exercise will run into the limits of Apache Bench before the limits of the server(s) being tested. The LigHTTP team has a multi-threaded clone named WeigHTTP that I would recommend if you want something that is functionally similar to ab and uses similar command-line arguments.

Wrk uses a slightly different argument syntax from ab and WeigHTTP but has some upsides:

1. Wrk is also multi-threaded.

2. In our experience, wrk is slightly higher-performance than WeigHTTP (~5 to 10%).

3. Wrk provides average, maximum, and stdev for latency.

4. Wrk provides a time-limited mode (rather than request-count limited), which is appealing for some test types.

In my experience, as long as you configure Go and node to use all of your cores, Go will benchmark better than Node in any permutation of these configuration variables:

Go 1.0.2 and node tested with ab.
Go 1.1 and node tested with ab.
Go 1.0.2 and node tested with wrk.
Go 1.1 and node tested with wrk.

V8 is a very fast JavaScript runtime; node.js is modestly quick at handling HTTP requests. But among the many features of Go is a high-performance HTTP package. If you've used both, it isn't all that surprising that Go's performance clocks in higher than node.

Just an aside. The Musk Hyperloop is not a pneumatic tube. The pnuematics in Musk's Hyperloop is to reduce friction and provide stability. It's not for propulsion. Musk's Hyperloop is more akin to an air hockey table.
We've known for a while now that the placebo effect is not just psychological; it affects real physical change.

In one experiment, when given a morphine placebo, patients reported pain relief, but when a morphine-blocker was silently introduced, the placebo morphine no longer worked.

It's fascinating and deserves more research.
The hard part of qualifying is actually not that people will lack the time, but people feel guilty about financially profiling people superficially. Just check the recent Oprah scandal. It could be said that the sales girl was 'qualifying' Oprah's sale and directing her to buy the cheaper handbag, but turns out that she had misjudged the book by it's cover.
Maybe the YC startups are the products? :)
Rail installation costs are no joke due to the need to precisely align horizontally and vertically the two rails.

The hyperloop sections would also need to be precisely aligned.

You can make tube in 50ft sections and ship them via truck without needing any special permitting

But you may need special routing for those trucks to allow overhead clearance and turn radii, and you may need to build temporary roads for access to the installation site. There are lots of little things that tend to add up that are ignored in the whitepaper. You may be able to reduce costs by a few percent, but 90% is not a figure that I can take all that seriously.
I guess this boils down to personal preferences. When reading a full page of text I usually take my hands off the keyboard/mouse and lean back. Not having to find the mouse every so often is nice.

Again, I'm not saying that using the Leap for OS interaction is ground-breaking and akin to the first time I ever used a mouse - it's simply a nice addition to my current setup.
Qualifying early and quickly is a must but for a successful sale to happen it must quickly transition to implicating the pains found and spending a lot of time there otherwise there's nothing to come back to and once hot prospects can go cold quickly. This is especially true for B2B sales with long sales cycles, not as much for sales which can be closed in a single meeting. The money is in the former.
Follow-up: lessons from my almost failed lunch.
First, just a note, you can only see that section if you're logged in.

Second, I disagree that it is 'directly against the rules' - no where there does it say specifically that you must not post solutions elsewhere. I think the intent is there - but if someone simply cribs off another answer somewhere, they're not really learning anyway and are really robbing themselves. Project Euler is altruistic anyway and there's really no 'advantage' to stealing answers. (I guess someone could show off their progress, but I don't think that's much of an advantage, since they aren't really learning anything)

I have learned quite a bit from looking at Project Euler answers from others and am glad they published their solutions. For example, there are many different ways to do #2 in Haskell and it is enlightening to see how they work.
Ha. Very true. Although, if you look out over the medium-term, NY is making a good case for being a challenger. Massachusetts has really seemingly squandered the advantages it has.
Not sure it is a good analogy. From the article you are referencing he wanted to be an engineer, just an agricultural one. WW2 changed that.

Also, he seems to acknowledge the fact that he was standing on the shoulders of giants:

But one thing is clear: before attempting to create something new, it is vital to have a good appreciation of everything that already exists in this field. I myself have had many experiences confirming this to be so.
No, a better example is Elon Musk himself. Paypal, SpaceX, Tesla. That's a pretty good run and I don't think anybody will claim he was an insider to all three industries before he made a significant dent in them.
Immigration isn't a panacea. You have to be able to absorb and acculturate those immigrants, and you have a finite capacity to do that.

This will yield down votes, but I'm an immigrant from the subcontinent and I understand what I'm talking about when I say this: it is vital to preserve western culture. Immigration done right can strengthen it and keep it vital, but done wrong it can dilute and corrupt the culture.

Germany is better than India or China or the Middle East or the other countries immigrants would come from. Full stop. Westerners don't appreciate the extent to which a lot of the bad things we perceive to characterize those countries is baked into their culture. Sexism, racism, corruption at the basest level. That will follow immigrants into Germany and take root there unless immigration is slow enough to acculturate the immigrants.
I think there's some room between "bad" and "great", though. My point isn't to accept a "bad" co-founder, but rather to not let the quest for a "great" co-founder keep you from going with a "pretty good" co-founder for so long that you miss the opportunity anyway.

That said, this is all pretty subjective and hard to measure anyway. I mean, do you really know that a "great" co-founder is "great" from day one? Or that someone you think is just "good enough" actually is "great"? Of course, that fuzziness is part of why I say "just pick somebody and get started already" to some extent.
"If Germany is to avoid a major labor shortage, experts say, it will have to find ways to keep older workers in their jobs, after decades of pushing them toward early retirement"

Doesn't it suck when a society is forced into valuing its elderly.

It actually seems responsible of a society to balance itself with its environment. Population overgrowth is a major issue in the world and I applaud the people of Europe who, and possibly unconsciously, are reaching a greater balance with their environment in the hopes of securing an actual future in it.

I don't see how he can say, "Well I moved stuff to a CDN and changed hosts off of a shared server and greatly reduced my CSS file size, but surely it was the fact I changed languages that caused my page times to increase!"

No, author, Go had very little to do with your page load times. Both Go and Django are going to serve a simple blog at the same speeds.
Correct, in fact in general families/women from lower income and education levels (no matter if immigrants or not) tend to have more children than higher educated couples that prioritize their career. Overall germany is also not a very family-with-children-friendly country. This is in stark contrast to, for example, the US.
I was surprised at how amazed people on one of the recent Go threads was with Go compilation speeds, given that gcc delivers similar compilation speeds for C code per line of code for me on my old, slow home server.

As for 16 bit systems, I'd love to see a comparison with the Turbo Pascal compiler, for example, on modern hardware. Maybe my memory is deceiving me and the program sizes just weren't comparable, but it sure did seem like it was just flying on a 4.77MHz 8086 based PC. It'd be an interesting comparison.

Especially given I remember how frustrated I was with a lot of other contemporary compilers (whether for C, Pascal, dBase or others). The only other compiler I remember fondly for being fast was the AmigaE compiler (by Wouter van Oortsmerssen, the strlen.com / Cube engine guy, who I see is now working at Google on Android gaming - nothing but good can possibly come of that)
Thanks, that's what I was asking about. Makes sense that the SEC allows this if the content is accessible to anyone without login and the content is crawl-able by search engines (i.e. easily discovered).
It's also 2560 m/s, or ~8 x the speed of sound.

I could never "get" what BlackBerry was all about.

> If society wants more kids, it should pay up.

This can only work if those who pay also get the benefits. Then the employer paying the support must get a cut of the adult child's income.
The terms of these initiatives (Fachkräfteinitiative, Blue Card) are so one sided and onerous that very few people from outside actually use them.

These initiatives, started years ago, so far have flopped.
Mature means many things, including being able to get support, packages, existing code, solutions to common problems, etc. I'm sure Go is a solid project.
After playing around with an Arduino in my spare time, I've realized how important it is to start thinking in multi-threaded concepts in programming. Nothing makes a better example than watching delay(); physical prevent your sketch from taking the next step.

Golang (Still can't believe Google would release a language so piss poor for SEO) WILL be the language I pursue when I start down this path, but right now I don't have any projects that force me to start rebuilding my libraries from scratch.
It should be illegal to show these maps without explanations like this alongside them.

p.s. not actually illegal - just severely frowned upon.
Working at multinational technical companies it is not much of a problem as the work language tends to be English.

However in many such companies employees might speak English with foreigner colleagues only for work related issues, leaving them alone for about anything else. Meaning little social interaction besides work requests.

Being invited for lunch while most of the table speaks German can be a common scenario, for example.

For an acceptable social life in Germany, having at least a basic grasp of German is a must have, specially outside big cities.

Your statement about the United States' available land makes the assumption that the American population is evenly distributed across urban and rural areas. In reality, more than 80 percent of the country's population lives in urban areas. The population in those areas grew by 12.1 percent between 2000 and 2010. Just because spacious rural areas exist doesn't mean that Americans are willing or able to move to them.

Must be depressing to think of yourself as a cancer cell. Who do you think is the host?
The concern is not that the old software magically loses its freedom, but that tomorrow's software will, as the software we develop simply gets adopted as the base for proprietary solutions that then strangle their still-"free" parents of that valuable development oxygen.

In that regard I think even GPL advocates would be quite happy to use your example about Darwin, at least as a cautionary tale (though perhaps there was more benefit for the BSD upstreams than I am aware of; we're still waiting for an open release of ARM Darwin...). Likewise Apple's adoption of KJS/KHTML didn't go as well for KDE as we had hoped.
That is good advice, but only works for national parks, and the closest one is 100s of miles away. There are not that many national parks east of the Mississippi. There are some, but its not like out west where it seems you throw a rock and it probably lands on a national park.

On the other hand the city I live in has three separate rails-to-trails conversions within 2 miles of my house and a riverwalk. Every little county park seems to pride itself on having elaborate marked hiking trails. In a land with lots of rivers every "three taverns and a gas station" village hovel seems to have some kind of riverwalk, aside from the big one in my hometown. Just one of the state-level parks in my county has 29 miles of hiking trails. I wasn't kidding about just my little county (well, little county as in half the surface area of Rhode Island) having 100s of miles of hiking trails.

I would like to hike a national park someday, but its so much easier (and cheaper!) to visit a local trail.
I'd be curious on cperciva's take on this.

Assuming it never goes above 5g (which from googling seems to be a realistic maximum sustained g-force limit), it would roughly mean accelerating at 5g for 1 minute, followed by 3 minutes of 6600mph, followed by 5g deceleration for 1minute

Sounds fun :)
Looking at Braintree's Marketplace docs, it appears you have to "onboard" each sub-merchant you want to send payouts to, which requires entering their name, address, date of birth, and their social security number. It then says "If [the social security number] is not provided, we will attempt to retrieve the full Social Security number based on the other applicant details."

So my question is: How is it possible / how do they retrieve someone's social security number using apparently just a name, address, and birth date? (Maybe I'm naive, but I thought socials were pretty secure)

This could have happened pre-internet through press. It'd a bit more more difficult logistically but this has always been possible.
I'll just add one thing. It's reasonable to criticize musk for 'not knowing things outside of his domain'. But claiming that musk knows nothing about the cost of building metal tubes, is really stupid. It's certainly possible musk is fudging the numerical values.
My suggestion is employers should receive money, not pay money.
A coworker and I have written some gesture recognizers for Leap in C# and Objective-C hoping to make the thing more usable and easier for other developers to write software using it. Hate to do a shameless plug, but both can be found here:

We're hoping to start the community foundation for making tools that help make Leap extremely usable from both a development and from a user experience standpoint. The Leap is awesome, beautiful and we think can be used in a myriad of applications.

> How - faking child births?

No - by faking employment to get the subsidy for mothers who don't want to (or cannot) work. And of course you'd have unintend consequences for wage levels.

> The point about the childcare thing is: the solution is not providing parents to get rid of their kids so that they can work. The proper solution would be to enable parents to work less and still have time for their kids.

How do you see those as two contradicting (or even different) things? Even if you "work less" you need someone totake care of your kid while you work.

> You think catering to parents with flexible work schedules will have a significant impact on birth rates? How many people does that concern anyway?

Many more than you think, apparently. Sweden's fertility rate is much better than Germany's (1.94) and they're the inventors of 24h child care.

you dare question a website with 'scientific' in the URL? I like your moxie.

I recall reading something posted recently about how the way the grants in social sciences is set up ensures that you get a whole lot of papers that have a catchy 'truthy' hook to them, which will then get disseminated by the mainstream media and quickly forgotten.

It basically turned the fields into little more than generators of soundbites.
Bad link buddy.
Freight doesn't care about speed, and does care about how much mass and volume you can transport. The capacity of the hyperloop capsules is tiny compared to a modern train.
Apparently (I'm no expert but my Dad is) it makes far more sense to transport people by train and goods by car. People will autonomously complete the rest of their journey when dropped at a station, but goods will not.

At least, so far.
Look at it this way: what is more likely, that you could help the new company get started with TDD and CI, or that your current company would give you a 50% raise and let you work with technology that you love?

Consider all the dimensions, including the point mchannon made that you can always look for additional companies to work for if this new one doesn't seem like the best fit, but if you think you will be happier at the new firm, consider switching.
There is not a huge amount of available fresh water to sustain a population several times the United States' current size.
The problem is, there are no good incentives to pay for you to have an 18+ year responsibility.

Pay to give birth? Wow, what a couple hundred bucks? Maybe a $1000? Pay directly for services that children would use?

The problem is, there is no good way to subsidize being a good, responsible parent. You have to want to be. And more people are simply opting not to have children.

Not only that, but although the particular test described in the linked blog post did not include database connectivity, we saw a massive increase in database performance in 1.1 versus 1.0.2 due to a fix in the sql package [1]. That was back in Round 4 of our project [2].

Just something to be aware of if anyone reading has Go 1.0.2 installed and has not yet upgraded. 1.1 is worth the upgrade.

By now, I'd assume the language run times are in the noise for thinking about maturity. The most likely culprits will be the application code followed by the library code. So the real question should be "Are there any big scary monsters in the libraries I need?". Followed by "Which language do I think will best enable me to hit my target?".
Paul Stamatiou wrote specifically about his experience with 4.2.

The author having not used Android 4 makes this a very poor analysis. I also hated Android <3.0 and loved iOS for years.

Then I bought S3 (and now S4) with Android 4.2 and the improvement was massive. Android only recently got their shit together (design & performance wise) and it's now very competitive with iOS. Arguably much better in favor of Android if you're a hacker.

Cyanogenmod is very easy to install. There's no reason to be locked into old versions because of your smartphone vendor (assuming you're moderately technically savvy).
