From a climate change perspective, yes. But from just a general air pollution perspective, a lot of effective regulation needs to happen for industries to stop pumping noxious gases into the atmosphere. There are hardly any limits on industries and they can pump whatever they feel like into the air. Catalytic convertors for factories ? Almost non-existent!

I know that the discussion of general air pollution is slightly off topic here, but it really is very bad in New Delhi, and eventually does reach the subject of climate change.

Another perspective: If India doesn't care about air pollution within India which affects it's own population, it's unlikely they will care about some glaciers melting far away sometime in the future and affecting people in far away countries.
Guys, this is science fiction getting real and this is kick ass. This is awesomeness. Kudos to JB. And I think this would work without having any big issues. Reasons are:

1. Amazon will wait for the FAA approval before deploying this . This means, the max. weight a copter can carry at any given time would be limited. As some one said, if AMZ starts shipping heavier packages beyond a certain limit there is a risk that it might be dropped and causes injury or death.

2. AMZ would not deliver it across cities. Pls. see the video. It's mentioned that it would be within 30 mins of pressing buy button. This means the radius of the delivery is controlled and monitored from either the fulfillment centers or a central control center.

3. Consider attaching a video camera for delivering the goods. It would also record the whole delivery process for many aspects. It would have a visual footage of who picked it up, whether it was delivered to the correct location etc. This covers legal aspects as well.

4. People would love to have this way of things delivered to them since they would save a lot of time going to the store, spending on gas, waiting in lines etc. oh..btw, this is good environment too. Less gas usage.

Now, the question is how would UPS, FedEx and USPS react to this? They would still be delivering the goods via road to drone inaccessible locations. What if the weather doesn't permit? Would not AMZ have a back up plan of delivering only to the places where weather is not bad? Why would they send the drone into a tornado effected area? Think my fellow HN readers. Think.

Now, the next aspect is security. Can someone spoof the GPS location and re-route the packages? May be. If that's the case, the video recording would help as mentioned earlier.

Walmart, you listening?
Unfortunately that graph is not terribly useful, even ignoring the "legitimate" filter— it both overstates transaction volume because lots of "non-transaction" events create transaction (e.g. consolidating wallets) and because it doesn't show transaction volumes of Bitcoin value which happen invisible inside systems (many Bitcoin wallet services will clear transactiosn between customers internally)
Hm? Currencies are primarily used as a means to store and exchange value. The other things are secondary features that you may use to do things like pick between two currencies.
fwiw, to be a DEA registered lab, and thus, have known marijuana (or other controlled substances) just hanging around, you've got to keep it locked up such that it requires two people to access it, and you've got to track it (very precisely) by weight. and the DEA can check your records any time. they have caught at least some people (who were "diverting" cocaine up their nose) with this.
I recall reading about shipments of Pentium (II?) processors being hijacked from trucks. I believe some people were even killed. The value of a truckload of new Intel processors is rather high though. Enough that someone may decide the risk in an armed robbery is worth it.
The argument usually hinges on simple counting: there are only 21 million possible bitcoins, and 21 million is nothing compared to the money supply of other currencies. Therefore, in the end (supposing bitcoin succeeds hugely), the exchange rate must be enormous.

So the difference between 1BTC and 0.1BTC is that there are significantly fewer of the former than the latter.
Those options are expensive. Why should the rich and powerful give up profit margins for better public health and so that other countries don't get typhoons ? Unfortunately, money is much more powerful than any other motivation. The government helps curb such attitudes but the government listens to the people (atleast in theory..), and the people are indifferent.
Well looking on the bright side, there'll be a lot of new jobs created as gas station attendants for filling all the automated vehicles... until that gets automated.
Care to share why? I've always loved coding in object oriented programming languages.
It's a common but incorrect assumption to think that replacing repetitive human tasks with machines leads to wide-scale unemployment.

Of course the delivery person who is replaced by drones is out of a job initially, but this doesn't doom everyone to unemployment. Higher productivity through mechanisation leads to lower prices, which means more cash available for other purchases, which leads to jobs growth in other areas and a rise in living standards. There are always winners and losers in any technological change, but the general quality of life for society as a whole improves when menial repetitive tasks are replaced by automation.

There are more jobs around now than there was at the dawn of industrialisation, and has been, every step of the way. This will continue to be true, despite difficult adjustment periods for individuals and businesses in effected industries. Stagnation is much worse than progress, and trying to regulate away technological progress is even worse than that.

I think the major applications for this are in areas where people can't quite imagine yet. Like the increase in internet speed and portable processors which ran ahead of services to leverage it, this type of infrastructure may start by delivering books, and end who-knows-where. Distributed aged-care with medication and meals delivered in-home? Some bizarre physical-world words with friends? The possibilities are quite exciting if it can be intelligently standardized.
From my last post:

>the idea is that restricting the enrollment period will cause uncertainty (or fear) that the citizen may 'miss out' on the opportunity to save money on treatment throughout the year.

I believe this logic shows that enrollment periods are reasonably related (, Supreme Court language for constitutionally permissible,) to the free rider issue. Whether it is a sufficient justification for government intrusion into independent decision making by citizens is a completely different, and entirely normative judgement.
Something related to this is the stuffed bread.

Why is the web so slow?
There is something almost colonialist about the way the arguments on the Indian side are never given (although their motives are discussed in depth).

Last time I checked, both China and India argued that global emissions limits should be done on a per-capita basis, and that therefore China and India should not be obligated to reduce their emissions.

While there are arguments to be made against this claim (e.g. should China and India be rewarded for their large populations?), it would be nice to see these arguments being addressed directly, rather than assuming that non-Westerners are only ever driven by base politics.
Has anyone used hunie.co?
I'm curious to know what you think about it. Do you like the experience? Are there things you love or hate? Do you feel like there is a need for this kind of community?
It's not realistic to expect patents to be granted more intelligently. We are by definition, in the hypothetical best case (all honest actors), talking about the absolute bleeding edge of technology, where you are going to need real experts to be able to discern what is "real innovation" and what isn't. I don't even consider myself capable of analyzing patents except for in an incredibly narrow slice of computer science where I've worked for 10 years, so I'm not sure where you expect to find these generalists who will one day be looking at AI algorithms and the next day be judging graphics code. The only alternative would be to literally have an expert from every subfield. Even if you had infinite funds to fill this magical patent office, why would such experts take this boring job (unless their goal is to work on physics on the side ;) )? As it stand today btw, most patent clerks being hired are engineers straight out of college, and I imagine they aren't exactly the top of their class. No one dreams of being a patent clerk.

This is all exacerbated by the fact that the patent agency is a government agency, where there really isn't anything incentivizing them to get better. And yet on the other side you have lawyers who are 100% incentivized to create the most convoluted patents to actively confuse (the already ill-equipped) patent clerks and juries.

I also agree with the statement "if we could just grant the right patents then this wouldn't be a problem". I just don't see any reasonable way to increase the fidelity of patent grants, nor a reasonable fallback system for when a bad patent DOES inevitably get granted (trial by jury for discerning innovation is probably the worst method).

1000 years ago you could be a mathematician, poet, and biologist. Today, you have to go to school for 5 years to get a PhD in an incredibly focused subfield. 100 years ago the patents you were dealing with were "machine that makes light". Now its methods of improving graphics performance when running on this super specific kind of computer architecture. It might have been reasonable for an outsider to make a judgement call before, but I seriously don't think it is anymore.

Holy hell. I can't think of anything scarier than the internet version of WalMart controlling all of modern consumerism. (Except, of course, Amazon's fingers reach into so many more digital pies than WalMart)
That is factually inaccurate. There are a wide variety of ETFs which have non-equity instruments as the underlying assets.
Well put.

I used to work for financial traders. I even used to have a brightly colored coat and a trading floor badge, back when that mattered. I've read The Economist for 20 years. Despite understanding the financial markets better than most, I never trade individual stocks. Everything's in low-load funds; I look at the allocations every year or two.

Why? Because I know what I'm up against. I have friends who are still in the industry, deploying vast computational and financial resources to make money. For any given stock, there are people who follow the company and its markets more closely than I ever will. And all of those people regularly fuck up, losing millions. I'm not interested in stepping to that.

And there's another big reason: it's a giant minefield of cognitive biases and emotional weirdness. For example, you can think of the market as a random walk with an upward bias. Year on year, you're generally up. But day by day, you're can be down nearly as often as up. Because of loss aversion [1], you'll feel the losses more strongly than the gains. Looking at your stocks every day will at least add to your stress levels, and maybe your decisions will get thrown off. (This example is taken from the excellent Fooled by Randomness [2], which I recommend to anybody who wants to trade, or even understand the financial markets.)

I focus my energies on areas where I have a an actual advantage, and I encourage others to do the same.

My skepticism is based around the fact that the video and information seem like a cheap trick to gain PR.

The technology is interesting and has a bunch of really tough problems that need solving. Amazon haven't even begun to acknowledged any of the issues, let alone begin to solve them. Instead they built a shiny video of a fake product to cash in on the enthusiasm for drones.

This blog post gives off the impression that you must beat the market to make money. Given the author's CFA and enrollment at a top business school, I'm sure the author knows this isn't true. But if I didn't know much about the stock market, I'd think it was zero-sum just from reading this blog post.

Nevertheless, I agree with the premise of this blog post, but I think the author should put more emphasis on the difference between passive management and active management.

Passively investing makes sense -- you can earn higher returns if you're willing to take on higher risk. Actively investing is what the author and I have issue with -- picking individual companies rather than trading the market as a whole.
Yea ... I just read some rumors of how Dropbox paid several hundred thousand to get their domain. That would make me sick...!

Non-technical startup in this case, consumer facing.
I assume you mean Kyllo, which I have a number of problems with (though I'm somewhat reassured by some of Scalia's points in the majority opinion). But maybe my imagination isn't good enough - what's the scary scenario with drones that Kyllo makes legal?
I can see an Amazon Prime subscription coming with some type of landing pad dongle. You lay out your mat & dongle somewhere, put in an address and the drone flies to the address, listens for the signal from the dongle and drops the package on the 'X' if the details match. My bank currently gives me a two-factor dongle for secure logins, same type of approach for authenticating delivery and indicating a safe landing area.

There is a lot of really interesting problems to solve to turn this into a commercial service. Would be very fun to work on.
With respect to (1), why would delivery drones fly at high altitudes? I suspect that the only overlap in the flight envelopes of delivery drones and of manned fixed-wing aircraft will be riiiight around the airport, and during horrible plane crashes.

(Manned helicopters are another matter, but how many of those are there really? Even in the big cities.)

What Tumblr taught me about writing
> a bitcoin-fork coin that has no value outside of the game, used for transactions. Seems like a cool idea to me anyway.

Unfortunately, without the right economic motivations the system isn't secure. Many altcoins have been exploited in the past. Perhaps as part of a game thats okay, but it might be hard to balance things so that the game didn't become entirely about exploiting its currency-thing.
AWS AUP Breach
there have been a number of other forensic scientists who've done pretty similar things for exactly the same motives.

a bunch have done similar things because they were just too lazy to do the testing.

others because they were incompetently trained.
I can't agree enough. Most (95-97%) of my investments are low-cost index funds. My strategy is built roughly off this article (http://www.forbes.com/sites/thebogleheadsview/2011/01/28/thr...), adjusted for what I see as my short, medium, and long term goals (eg okay with some money in riskier, higher-return target assets for retirement savings, some more conservative things for saving for house downpayment, etc).

That said, I do the occasional amateur stock trade with a small amount of funny money. Much to your point and the OP's point, these often go against me despite my hunch. CF my recent purchase of TSLA at $145 ('buying at the bottom') and my recent sale of bitcoin at $350 ('sell before the crash and buy back in').
I mostly agree, but what of stocks with clear value (say utilities stocks with consistent dividends) that are underpriced due to a market downturn? The market isn't 100% efficient and there are plenty of dumb investors who follow herd mentality.

EDIT: To clarify, this is a question; the article seems to be based on the assumption that the market is perfectly efficient; I am wondering how does the fact that it isn't factor in? I would think that one could make money by being reasonable in the face of unreason.
I know the poster before you got a lot of down votes. But I thank you both for asking and answering a serious question. It's hard to comprehend that situation until you are stuck in the middle of it.

I hope eventually drones will just deliver raw materials and resources for product materialization (next generation manufacturing) at home or on-site, using both commercial and open source product materialization specifications distributed electronically.

True, I don't need this exact domain. However, it was a pretty good one amongst the ones I brainstormed, so I don't mind paying some amount >$10 to get it. Trying to brainstorm now to see if I can think of a better one.

Catalytic converters operate at high temperatures, (600 C,) which is much higher than the exhaust temperature of most factory exhausts; thus they would not be compatible. In addition, most emissions from factories are not un-combusted fuels (which CCs process), for a couple of reasons including the simple fact that most industrial processes which emit exhausts are run at steady state, and have been optimized to the point where nearly all the fuel is utilized. Particulate emissions are a real issue, as are dangerous vapors, but these are eliminated by various other remedies (such as filters and other sequestrations).
Another option is to rent with an option to purchase.

If they want $5000, you can say, "I'll give you $100 in year 1, $1000 in year 2, and purchase it for $10,000 in year 3"

If the business is successful, $10,000 hopefully will not matter. If it isn't, you don't have to pay and the owner keeps the domain.
Your point about the importance of pixel density is a good one, but the pedantry is misplaced. Resolution in the context of display resolution has referred to pixel count, not pixel density, for decades.
I like the idea that in the future the only people manually operating cars and motorcycles will be doing it for fun rather than for the drudgery of daily life. That sounds like a better place to live. If the net benefit of driverless cars is reducing vehicles on the road and reducing traffic congestion think about how much more fun it will be to drive?

The driverless cars will automatically take the safest action and let you through when doing something reckless like cutting them off on the freeway etc. It kind of sounds amazing, you could be a total asshole on the road and no one would care... Imagine cruising down the freeway at 90MPH in rush hour swerving between drone vehicles and watching as they politely get out of your way. Its a driver's utopia
What is good about insisting that the two combine functions be binary? And what is good about forcing a specific method of forking (evenly sized chunks)?

The more fundamental idea seems to be to use three steps: a method which takes a collection into sublists (fork), a method which takes any number of parameters and reduces them in a single thread (reduce), and a method which takes some number of reducer results and combines then (join). For something like string concatenation, non-binary can help avoid the need for an intermediate linked list. For something like matrix multiplication, or something that might require spacial partitioning, explicit forking is really important, as size and order can have have a major performance impact respectively.

Then again, this is a decent default approximation for many cases.

One of the things that I love about RFCs is that they're an existence proof.

Sometimes I'll get asked, "How can we have a successful organization without a lot of top-down control of X?" where X is something like architecture or process or coding standards or furniture choice. When people see problems, they imagine solutions pushed through a power structure. And of course, they imagine themselves as the ones in power, forgetting how many bullshit edicts they've had to deal with over the years.

The Internet and its RFCs are my favorite existence proof that you don't need centralized control to get good design and reliable systems. Indeed, you could argue that the Internet, beat out the other early networks because it wasn't centrally controlled.

So, Ed Davis is sending officers to threaten people who, from a legal perspective, have not been convicted of a crime and have been erroneously jailed for years. Lovely. That's really icing on the cake.

I'm not happy about putting potential dealers back on the street, but we are a nation of laws, and these people will be freed by our courts. You can't have the police commissioner sending people to threaten them.
