So, I get that so far this is just an Amazon publicity stunt and there isn't actually anything here to talk about.

But give them some credit. Most of these problems are solvable. You can build a drone with bumpers around the propellers and screens above and below, to solve the "sticking finger in the propellers" problem.

You can deal with the vast majority of the navigation problem by just getting enough altitude. Above a certain altitude, you don't suddenly see new unknown buildings springing up out of nowhere, and don't need to worry about navigating around power lines or anything of the sort. Just do the takeoff in a controlled area, rise up to an altitude high enough to avoid anything but a few pre-programmed skyscrapers and radio towers, and fly to your destination at that altitude.

And you can solve the landing problem by having someone sit in a control room and take over for the landing and takeoff from customer locations. Paying someone for two minutes worth of landing and takeoff is much cheaper than paying them for the full 30 minute delivery time, along with the expense of a full sized vehicle and insurance that goes along with it.

Everyone seems to worry about the liability aspect, asking "what happens when one of these falls on someone". But we already deal with liability issues with cars all the time. Heck, we deal with the issue with planes as well; planes do sometimes fall out of the sky and kill people, but you don't hear people saying that delivery by plane will never work. That's just built into the cost of delivery. Drones are much lighter, don't have tanks of gasoline, and flying in the air gives you much more open space than driving on roads. And you could probably add a failsafe that deploys a parachute if the drone loses power or otherwise start to fall.

The big problem is flight time. Batteries just don't have the energy density to support long flight times; you can build ultra-light drones that get an hour of flight time with a lot of care, but if you're building something that's actually going to carry packages, deal with wind, and so on, 30 minutes is probably the upper limit. That means that you won't be able do trips of more than about 15 minutes each way. Now, since you can go in a straight line, without traffic, that gets you further than a 15 minute car/bike delivery, but it'll still be limited to people who are fairly close to a distribution center.
Additionally IQ to understand different fields varies as well. One who is able to understand math quickly will not be able to understand language or emotions quickly. Even saying that one has higher IQ in math is not correct, one able in set theory or may not be good in calculus or statistics since those fields may involve different mathematical skills.
Forensic science encompasses a broad range of things, including bullet-lead analysis, arson investigation, handwriting analysis, fingerprinting, etc. Various techniques have bordered or even crossed into pseudoscience, others have wildly erratic error bars that are never properly considered. There are so many problems because the entire field does not treat their discipline as scientists do, they are too close to law enforcement for that. Techniques are used for decades before anybody bothers to properly figure out if the technique actually works.
Why not add line breaks using your text editor? That will also help your collaborators who prefer not to wrap long lines.

I have a hook in my .emacs that turns on auto-fill-mode whenever I open a .md or .rst file. I'd assume there's something analogous for vim or whichever editor you normally work with.
Well its been working well for me. I approached it with favorable starting conditions though (CFA/CPA background, young enough to absorb dangers & I play in a market that isn't full of Goldman style players).

That being said I push everyone towards EFTs too unless I can feel this person has a reasonable shot at actually not getting murdered on the market.
I hadn't thought of that, but it does make sense. I've added in issue to the repo: https://github.com/rpicard/explore-flask/issues/16
i find it easier to start with a neutral view and then research a topic before arriving at a conclusion. time considerations aside, coming to conclusions via thorough research about even mundane topics is a great way to practice/utilize critical thinking skills.

trying to argue for the "other" side can get quite complicated for complex topics, like religion.

Autonomous wheeled delivery would seem to accomplish Amazon's goals with the benefit of reduced cost per lb-mile. Vertical thrust air transport is very inefficient compared to ground transport - more energy is spent maintaining altitude than moving forward.

Autonomous ground delivery does suffer from reduced navigational flexibility (anything other than curbside delivery is tricky). But it potentially has lower operating costs and safer failure modes. It may also be easier to integrate into existing regulatory frameworks.

> Google Docs clones the Excel formula language for use in cells but allows you to write extensions/macros (where you would use VBA) in Google Apps Script but what is it really? It looks a lot like JavaScript.

It doesn't just "look a lot like JavaScript", it -- to quote Google -- "is a JavaScript cloud scripting language that provides easy ways to automate tasks across Google products and third party services and build web applications." [1]

[1] https://developers.google.com/apps-script/

> Why not have a single language for the cells and for extensions?

Because programming in the extremely small is different than programming in the large.

With a suitable functional programming language, you could probably find something that would work tolerably well for both.
You can run Android apps on BB10. But there would be no point in running Android, it would be a big step backwards security wise.

Not to mention that Google don't do Android out of the goodness of their hearts. They want to make phone handsets commoditized with all the cool stuff in the software and in their "cloud". That's not a market you want to be in as a manufacturer - just ask IBM who were driven out of PCs, a market they created...
I don't necessarily want threading in Node.js, but it would be nice to have coroutines/green threads...something simple that scales across CPUs, at least. Unfortunately with JavaScript I think the best you're going to get is Node's cluster module, because of the threading limitations with V8 and other JavaScript engines. Realistically, it's a trade off - Node.js is easy and quick to work with, but the only way to take full advantage of the machine's processing power is through forking processes.
Agreed, the stories sunk include ones like the Anandtech review of the Surface Pro, and the site is quite reputed for being neutral, however the excessive number of comments combined with not too many upvotes can easily sink articles which are otherwise just news and this contributes to the filter bubble(funnily there's a anti-filter bubble post right near this article on the front page).

I try not to use anything related to Google. This includes their technologies like Go and AngularJS. Not that the NSA has necessarily compromised those too, but it's a matter of principal; the same reason I don't shop at Wal-Mart or eat at McDonalds: I do not trust them to do the right thing.
Actually Buffet is talking about investing in an index fund VS investing on the advice of an investment professional. He is referring to the same biases of professional investment advisers that the previous poster was referring to. Basically ordinary investors do have an asymmetric advantage over investment advisers and 'professionals'.

Hence, it may not be your intention, but you are using Buffet's quote to make the exact opposite point of what Buffet himself originally intended. And he has often spoken on this subject. See also Mohnish Pabrai and his book 'The Dhandho Investor'.
good writing is mostly good editing

Absolutely. What the internet needs is some collaborative site where people can trade editing for article submissions. That way everybody can get better at their editing skills, which is where the real impact can be made.
Oh, that's the thing. In a patent, you only have to describe the general idea. It's not like you put source code or anything useful.

But that's the problem: no matter how many variations of the obvious you list, they'll find something to patent.

I skimmed thru and this caught my eye "Our EMM customer base is much larger than any of the other vendors in the Gartner Magic Quadrant for Mobile Device Management – and is growing."

I wonder if "Flask for recovering Djangonauts" would make for a good blog post / tutorial. It might even be enough material for a video course. Best practices, advice, and good libraries are what I'm shooting for with Explore Flask, so hopefully that will come across.

As far as official library integration goes, I wouldn't worry about it too much. There are several standard extensions that people use (e.g. Flask-WTF, Flask-Bcrypt, Flask-SQLAlchemy) and as long as you stick with them you'll be alright. They're usually just wrappers around major Python libraries (WTForms, Bcrypt, SQLAlchemy) so the source is easy enough to check out.

This is just yet another sensational climate change piece on a pop-culture website. The authors qualifications? Tim Donovan is a freelance author who blogs about Millennial issues at The Suffolk Resolves.

At his personal site we learn "In 2006, Tim graduated from Emerson College with a BFA in Writing." Nothing wrong with that, but it's nothing that gives him any credibility in a serious discussion of climate change.
Agreed - people will always find holes to poke for no reason. They aren't the ones innovating.

Practical Abstraction using Ember.js
As an extensive user of named cells, one problem I have encountered with named cells is that copying-and-pasting to run a parallel scenario often results in a mess up -- cells in the copy inadvertently referring to the old cells, etc.

What would help is some sort of object-oriented programming with the named cells as opposed to the named cells behaving like global variables.
I'd love to see this, but also including exchanges across different currencies (e.g. CNY) and normalized.

Kind of like http://bitcoinaverage.com/ does, but with a nice chart like http://bitcoinindex.es/.

I suspect the visualized data will be much more interesting, since different local economies behave differently. For example, when BTC was "crashing" yesterday to $850 USD, Chinese trades were still holding well about $1000 USD. Eventually the arbitrage opportunity becomes too big and the gap is closed. Watching this is fascinating.
I wonder if they asked for permission?
Moving 100% to Android would mean a partial write off of the QNX purchase but they have alternatives such as supporting Android side by side via virtualization. People will have the best of the two worlds. I think it is impossible for them to attract developers and fill an app store in the short term.

withdrawing USD from mtgox and transferring them to btc-e takes roughly two hours, depending on which payment processor you choose. okpay is usually pretty fast, but you loose about 50$ on commission. furthermore unless you are verified on mtgox, you've got a withdrawal limit of 1000$ per day. add to that the time interval during which your money is locked up either in the blockchain or the payment processor and you end up with substantial risk between the trades.

EDIT: This only worked until the end of may - I've just noticed that OKPAY withdrawal is no longer an option: https://www.mtgox.com/pdf/20130528_okpay_statement.pdf
138 Cryptolocker C&C domains identified, taken down
I already mentioned child processes, which model scaling up to multiple servers better than threads do, are more powerful than web workers, and are supported out-of-the-box with a powerful arbitrary message passing schema including the ability to transfer sockets between processes. It looks like there's some abstractions built around using multiple processes and work queues to help amortize the weight of the additional processes (see node-compute-cluster mentioned elsewhere in this thread), but I've not used anything like this.
I understand the endless desire to tweak, I really do, but HN simply doesn't have anywhere near the volume of posts Reddit does.

This place has the same feel as:
http://www.reddit.com//r/depthhub

Most of the action is in the comments and a lot of the traffic is from lurkers. Its a slow roll in other words and frankly there is a very finite amount of good quality new posts to be had.

That is the real problem - try and rank this place more optimally by hand as an experiment, it simply won't take that long. Where is all the great content you are trying to algorithmically float?

In a world where grant funding is extremely limited, yes. Funding agencies are looking for any reason to reject a grant. I think the only reason to not retract the grant(s) would be the difficulty / practicality of doing so.

Forget the abusive submission tactic and look at the article itself: far from being "important" for HN, it's entirely off-topic; less germane even than a common political article, this Salon piece is a shrill tour of seemingly every political position Salon endorses, tied together not with a coherent thesis but rather an overt suggestion that the world is ending.

You submit some great stuff, Ron, but I'd like to suggest as respectfully as I can that we'd all be better off if you took Salon off the list of sites you submitted from. It's not that there's never anything good on Salon (I got my favorite caesar salad recipe from Salon!), but the stuff you pull from it tends towards the (large) divisive, partisan, and unproductive portion of the Salon spectrum.
The fact that there is a gap that large between exchanges is indicative of a huge liquidity problem in the exchanges. Big enough that I wouldn't go near it...even with my arbitrage-loving mitts.
Use an IDE.

I don't mean to trivialise a very real and hard problem, but the world being what it is, cut yourself a break here and let an IDE do the heavy lifting of allowing you to navigate and help understand a code base.

You'll NEVER be able to guarantee all APIs you'll ever work with are adequately documented. That path leads to madness!
It comes down to whether you think it's moral that one person filing paperwork with a bureaucrat grants him the right to haul other people who independently think the same thing he did into court, trying to take their property. Patents are tantamount to the creation of thought crimes, on a vast scale.

Furthermore, if you aren't against patents in general, there is no principled argument that can be made against software patents in particular. Software is just as inventive as other realms.
Just take into account the value + size of the BTC portfolio. It's over 1m bitcoins now. If this was a conglomerate of some size and the value of the portfolio grew from $1m US to $1b US in such a short time, wouldn't there be a lot of pressure to sell and take a large amount of cash for each shareholder? I'd think there would be a LOT of talk about that and that, yes, it would be likely to see each person taking $10m US out at the very least. So, anecdotally, I see the fact/appearance that this hasn't happened as evidence that Satoshi's bitcoins are owned by one person. One person who owned so many BTC could sell enough to raise $10m without anyone really thinking much about it. But if a group of twelve, for example, owned that many bitcoins and each wanted to pull out $10m in cash, that size of a transaction goes noticed. Wasn't it just last week that someone did a $147m BTC transfer? It made headlines everywhere.
I thought it was pretty good. Have you managed to break into a blackberry and extract the user's info without it being wiped out?
Show HN: My final project for my human-computer interaction class.
Honestly, does it really matter if someone reads the articles that you submit or not? Come on now, stop taking yourself so seriously.

The rules of Hacker News are pretty simple. The articles are submitted with the titles of the article. Sure, sometimes it doesn't work out well, but most times it does. And it significantly reduces decision making time for the moderators, which given their work, is likely much more important than your vanity of getting karma points.

If you want people to pay attention, why not post it to reddit or some other forum?

You can do that with Excel 2007+ with tables, which are probably one of the best improvements in Excel in a long time, and underused because so many Excel users have spent so much time learning how to work without them they failed to notice that it was no longer necessary, and that the most common Excel use cases had just gotten much easier.
AI That Finds Good News
Might have been a better choice to make your point about headlines to not use an example that is flame bait and slamming a significant percentage of HN's readership, pg included. Blaming boomers for everything wrong with this planet is a little over the top. They are one generation among many.

Earth's likely demise will be the massive increases in fossil fuel use in places like India and China, and the failure to control population growth in places like India.

The EPA was created in the 1970's. Its mostly managed to push all the pollution intensive industries off shore to China and elsewhere.

It was also a serious mistake to carry the Western lifestyle to places with billions of people largely unmodified.

Any environmental choices made by boomers in the developed world will trail to insignificance in the face of China and India's choices. India in particular is the one currently obstructing the Kyoto follow on talks in Warsaw.

In other words, if the recommendations are based on similarities in your interests outside the disagreement then you may be less likely to find them "stupid".

True, but in a far smaller font than the headline "An Open Letter to Customers", which is technicaly the first line of this statment. But hardly good when such confusion is evident, heck BIS was enterprise and BES was consumer, see why people confused with such magical boundaries of consumer.
The meaning of the word masterpiece has shifted over time. As you say it used to mean the work that proved to your peers that you were ready to enter the profession as an equal. So certainly competent, maybe even considerably above average since so it marked an important event in the artisan's life, but still an early work.

Now it is more synonymous with magnum opus, among the very best works of an entire career. Perhaps ironically, with respect specifically to the dissertation it is a common mistake to try to create a masterpiece in the modern sense rather than the classic sense. Probably because every field has legendary careers that were launched with the publication of a game changing dissertation. This is one thing that can cause ABD to drag on forever.
quasi random number sequences [1] are "space filling". A typical problem of sampling from the uniform distribution is that parts of the space never get sampled due to sampling bias. Quasi-random sequences ensure evenish distribution. This speeds up many sampling based algorithms e.g. MCMC, by an order of a complexity level.

I too believe random numbers are usually the wrong choice.

Great point! Yes, that's exactly what this is: use-after-free. That's why I am saying that this is useful when you are trying to somehow break the program, but not useful when you are doing constructive things. Presumably, when you are trying to break the program, you can run it multiple times, and chances are that at some point the interrupt will not happen.

I've not seen this particular presentation, but I have seen several of his other presentations. The author is a gifted and enthusiastic presenter, and I seriously doubt that this presentation is a crock. Not least, he has given it before, and is invited to give it again.

You are basing your conclusions only on the very small parts that provoked this particular incident.
While it is hard, impossible is a stretch. You can buy drones with autopilot that will land at a point as long as you have 10 ft of clear space. A friend yesterday was using one he'd received for $3000 to film some cliff tops while we were walking the edge. After shutting off the remote it can fly back to where it was turned on so you don't have to carry it. Bear in mind this is with tech that's a few years old.
