Based on previous businesses that've offered Bitcoin loans, a common reason to borrow money in Bitcoins is because the person has no intention of paying off the loan. It doesn't take a large proportion of loans going bad before lenders start losing money on average at any reasonable interest rate, and increasing the interest rate will just increase the proportion of bad loans to good loans.

Very cool! It would be great if you would provide common usages for a given command if the user didn't provide any switches. That could be links like the ones you have in the "examples" section on the landing page.
> I can hover over movie.mp4, but I can't scroll down the see the description without losing the emphasis on that path. I'd suggest letting the user click on the portion, or perhaps a long-hover effect?

What if the command was simply pinned to the top of the screen as you scroll down? This would require some trickiness to make the atoms remain connected to their documentation as the documentation slides under the command, but would allow you to view any documentation on the same screen as the command itself.

EDIT: On the other hand, I just noticed that there are buttons to only show the documentation for specific subcommands, so you can always use those to cycle until the documentation you want to see is visible.
Are there other types of drones other than traditional quadcopters, for example variable-pitch quadcopters [1], that can get more airspeed and thus cover more distance in 15 min?

What about using airplane-style drones (like traditional RC planes) + a parachute to land the package? And this way you could use nitro gas fuel to get better energy density (since you can use one big gas engine instead of having to use four tiny motors)

The explanation for "du" and its -a flag make it sound like I'm trying to find out how much disk space my files are using. Fine, that's the usual usage, but the point here is that it lists out every file under the current directory.

The bigger problem is grep. We're told that grep prints lines matching a pattern, great. But then the explanation of the arguments makes it sound, to the uninitiated, like I'm giving "foo" as the filename, because the site doesn't include the actual grep syntax.

It doesn't really explain what the command line is doing. It does seem to do a decent job of telling someone who's already fluent in shell usage the specific meaning of all options given. That's actually pretty important these days where any given GNU util will have flags for every single letter of the alphabet in both upper and lower case.
It seems disingenuous for this blog to suggest that MacKenzie Bezos's negative review of the Bezos book was part of the same orchestrated spin campaign as the drone story. That review didn't simply object to the tone or the message of the book, but also pointed out specific factual errors the book made, errors that were later tacitly acknowledged by the author.
I deployed Fireeye over a year ago, and can confirm it's very good a spotting malware that most AV vendors don't. I can't, however, confirm it doesn't have back doors so that three-letter agencies can't tell it not to detect something they don't want it to.

If he can't see that adolescent boys will generally not be on their best behaviour, and will almost always take rebuke from a stranger on a stage -- that they don't even want to be in the audience of -- as a challenge to be met with volume...well he doesn't get it.

Ironically, perhaps, he's running the same game as the adolescents in his defense of his actions. I didn't do it, you misunderstood, it wasn't that bad, so what anyway, eff off if you disagree, I'm a great speaker so you're obviously wrong, etc.

Apparently it penalizes articles if number of comments > number of upvotes, so I doubt much analysis was involved - it's unlikely that it would result in such a simple ratio.
It would be presumptuous to think we can understand all those aspects, yes.

That said, I want to clarify something. When I speak of evolutionary fitness it is not a judgement of the individual regarding their actual value to the species or society. Evolutionary fitness is, really, a cold thing. It only matters whether the individual/species reproduces/survives. The dodo was an evolutionary dead end, even though the cause of extinction was humans, a pressure was applied that the species could not overcome. An individual that does not reproduce is another dead end. We, as a society, may look upon a Harrison Bergeron as the epitome of fitness (mental, physical), but if he's shot down before he can reproduce evolution doesn't care about him, his fitness is nil.
Exactly. Process tracing is applicable to everything.

My personal favorite, that I'm always painfully reminded of when reading political news, is the ability to hold multiple interrelated systems in your head at once and check that they're mutually consistent. There's so much unintentional doublethink out there that I think could be significantly improved if people would just stop and walk through their own thought processes in a logical manner. It's not the only way to think, and it's not appropriate for absolutely everything, but it is a good sanity check for many, many domains, and it's frustrating when people tend to look at me funny and end the conversation when I try to, for example, explain that two ideas cannot possibly be held at the same time because they're contradictory when taken a step down the line.

Come to think of it, the concept of a sanity check itself is something that I got from programming and use in everyday life.

Changing things. Honestly I don't think you understand this at all. You're acting as if by collapsing the government it would instantly pass to a more preferential party who would reign in the excesses.

In reality there exists no such party, no such majority. Who would step in to carry out these actions you desire?
> Where do you get the idea that the EMH assumes perfect information?

The grounding of the EMH is a consequence of rational actor theory which assumes perfect information.

It could be true without the rational actor theory more generally or perfect information in particular being true, but there is no reason to expect it to be true except the assumption of those theoretical foundations in which it is grounded.

Its difficult to falsify the EMH, since it doesn't actually rule out any outcomes, it just asserts that if market-beating outcomes occur, they are because of luck rather than strategy. As such, there is no result that is strictly inconsistent with the EMH. (Further difficulties arise since, if one rejects the EMH, but still assumes that market participants do efficiently apply the information that is available to them, any market-beating strategy would need to be kept secret to avoid being adopted generally in the market, and thus no longer be market-beating, so any test of EMH has to be able to distinguish between result of luck and results of covert strategy.)

What is the difference from regular https?
It's the other way around, really. News organisations want to be relevant, so will all have been looking around for Cyber Monday stories. This "narrative shift" is just a way for Amazon to make sure the stories that ran prior to and during Cyber Monday were not about working conditions in its warehouses, its international tax arrangements, or the death of independent retailers.

An organisation can very effectively dictate the precise timing of a story's running using tools such as an embargo (which determines the opening of the publishing window) and pre-arranged release of the story to other media (which tells an outlet with an exclusive that they should be publishing before this time). So a conversation along the lines of "We've got this great story, would you treat it properly if we gave it to you on 1 December, ahead of when it hits the wires at 8am on 2 December?" does the trick nicely.
This is a really useful service for what we call "version tracking," and it looks like it's running Brakeman for you too. With that said, it won't find vulnerabilities you code in yourself - only publicly released vulns that Ruby, etc. have issued patches for. A tool like https://www.tinfoilsecurity.com can help you find more vulnerabilities that either a) haven't been found yet publicly or b) you've written in yourself. (Disclosure: I'm the cofounder)
Maybe worry for all of them. I would. If I had a dog.
Though less helpful if you're trying to simulate an actual market rather than building a new one, another approach to designing a trading market is to use market scoring rules, which can be somewhat simpler conceptually (as least as far as the code goes):

No, this is not the same as a null pointer. Null pointers are typically much more sneaky, this line means the header will not be written and the error is right in your face.

I do understand the desire to prevent these sorts of errors at the language level, but not at the cost of functionality. I don't agree with this one, but I do (for example) appreciate libraries such as the STL which (hopefully) prevent that pointer issue you brought up (and more). The STL doesn't (often) force me to work around silly limitations though.

Does this library provide for creating arbitrary headers in some other fashion? If not, why?
Don't give us that BS. Make is braindead simple to use. There's no such thing as a Make/shell expert.
why not just use the delivery (UPS/Fedex/etc) trucks as a base station for the drones?

Pull in to a neighborhood of, say, 500 residents; Say you have about 100 packages to deliver... Set up 5 drones to deliver packages. Even if it takes 60 seconds on average for each drone to deliver and return, it probably is still much faster than the truck driver having to drive into every street, stop, grab the right package, drop it off, and go back to the truck and repeat.
Looks good. Perhaps add BTCChina, and label the horizontal axis?

Investopedia is incorrect. It is not impossible under EMH for particular investors to consistently beat the market over long periods of time, it is just improbable. Given a large number of investors, however, improbable runs of good and bad luck are near certain to occur somewhere in the system.

This is one of the reasons that it would be very difficult to disprove the EMH even if it were false -- there is no set of outcomes that is strictly inconsistent with the EMH.

The same can be said for most popular classical pieces. As someone who mostly listens to classical, I'm not even sure your characterization carries any meaning. But lets not elevate classical music to some rarefied pedestal; the vast majority of the good classical music contains "loud sounds and nakedly manipulative melodies".

Amazon.com to introduce drone delivery - Prime Air (Images & Video)
Sure, there are potentially other designs that will get somewhat higher speed, though at some point that will require enough extra power that it won't be worth it.

Airplane style drones can fly further, but navigation is more difficult, and parachutes will pose a lot more logistical problems than landing quadcopters (or, more accurately, multicopters; they used octocopters in the demo). One of the nice things about multicopters is how easy control and navigation systems are compared to something like an airplane or traditional helicopter.

The biggest improvement would be from better battery technology. Battery technology is improving, but very slowly compared to, say, transistor density.
While I agree the 60 minutes segment seemed like a commercial, I don't understand why one would waste time attacking this innovation (not the helicopters, but the logistics behind it). A more meaningful discussion would be what the actual objections of the FAA are, what the repercussions of drones in the air are, etc.

The impression of that change in the US media seemed to be "oh my God, look at those overly politically correct Europeans inventing words to be politically correct" (when they noticed it at all).

What was the impression on the ground in Sweden?
Yes, I bought TSLA options when the stock was at $30 and sold them for a 4x return. It grew to many more times that, so I could have gotten more.

"So what was it that you saw, that institutional investors missed, that caused you to buy?"

At the time, there was a large distrust in the financial community that Tesla had the production capacity to meet its Q42012 sales goals (I believe it was between 3-5k Model Ss, they ended up selling 6k). It further followed that Tesla failing to meet its sales goals would undermine investor confidence in the company and squeeze TSLA's operating capital in the coming 1-2 year period.

I disagreed with both hypotheses. The funny thing is, my strategy wasn't even smart. I know nothing about Tesla's production capabilities, what the bottlenecks were, or if they were likely to succeed. I assume that information had been priced into the market. Essentially, I bet on Elon Musk. I don't know what the bottlenecks were, I saw the Model S and shit my pants and said "This is awesome" and then I bought options.

I really only have one point to make, which is that if you think TSLA going from $30 to $180 / share in less than a year is a completely random, unguessable market move, well, I don't know what to tell you. It's not to me.

That has been my experience. I don't deal with them directly, but we have people on our team who work closely with them when it comes to unmanned aircraft.

I don't like Go's large number of inconsistencies.
This includes the builtin function/keywords: len,cap,new,make,range and the built-in types: map,lists,arrays.

For example, as long as you were going to have built-in functions and keywords like len and cap, why not make them pretend to implement an interface so that user types could implement them?

Why can functions return multiple values but not channels?

Why vary range semantics between the different collection types? Seriously the first value over lists should be the index? Most everything else returns an error, but channels return ok for a second value?

They don't allow generic user types, but didn't even bother to adhere to some standard syntax for specifying the types in the built-in collections. I.E.: chan type, map[type]type, []type Sticking to some kind of system would at least give a preview of what user generics might have looked like. Now if they ever do implement generics they'll have to figure out some crazy system to make the built-in types make sense (or deprecate the old syntax).

There is a lot to like about Go, but I can't help but feel that re: hype, Go is the future MongoDB of PLs (overall I like MongoDB too).
Doing burpees twice a day a year is better than not doing any exercise at all. True, it's best to have a goal, and to push yourself, but sometimes just building the habit is the first and hardest step.
HN still uses tables for designs. There's a mix of CSS and <font> tags. The login/register page has no styling at-all. Searching is handled by a third-party (HNSearch). Your top-bar color won't persist on some pages (ie. submit).

HN has a lot of issues but yes, by far the most annoying is the link expiration.
Also even if the book '... portrays Bezos as a ruthless tyrant and a "penny-pinching ballbuster,"' would that dissuade anyone who was already planning on it from shopping at Amazon?

My Intro to Operating Systems class was in Modula-2 circa 1988. I really liked it. I was lucky enough to subsequently spend quality time with Modula-2 on the 8051 and Modula-3 on Ultrix (which was a really nice evolution of the language). Shame that line of innovation has withered.
The UI with the svg "wiring" is awesome. You should consider abstracting away that functionality so that it can be reused by other projects.

\vec{F}_B = q \vec{v} × \vec{B}
| | | | |______magnetic field

In all of the criticism, I haven't seen anything remarking on the energy cost for this. I can hear a strawman in the audience saying "But drones are tiny/electric/cheap!" Not at these scales. Consider the (lack of) efficiency of quadcopters, the weights and distances involved, and the total sales volume for this service in even a small test market. I'd buy that flight itself is a viable option over wheeled vehicles when you consider more direct transit, reduction in delays due to traffic, and the reduction in weight of the delivery vehicle, but I'd imagine this advantage would only exist for fixed-wing delivery vehicles, not quad/hex/octo-copters.

$20 says that if this ever happens in the real world, the delivery vehicles are mechanically very different from what's shown in the promo video.
