It never occurred to me until now that you could use drones to commit petty theft. Not even of someone else's goods--stolen credit card + random residential address + drone waiting to pluck the package off the doorstep = profusion of "brand-new-in-box" laptops into the secondary market.

I suppose the challenge would be hiding the drone, especially before drones become a ubiquitous consumer-good... but I suppose you don't have to meet them at home; any flat rooftop is a valid place to drop a package to go collect, or a valid "overnight parking" destination.
Getting shot in the face by some dickhead who camps in the bushes then getting teabagged is not my idea of next-gen.
Whoops! Sorry, didn't realise I had submitted something that goes straight to a comment...
So, this is the wave of the future. Now, how do I make money on this, apart from buying Amazon stock or starting a drone company (which are going under in droves, I should add)? Is this going to be a first-past-the-post thing? I can't see how any other retailer will be able to compete with this, once they start rolling it out, and assuming they won't be offering DDaaS (drone delivery as a service - you heard it here first folks). I'm not sure how much the marginal delivery costs for Amazon are going to be, but this might give them a 10% (!) increased profit in an already very low-margin market? That would obliterate most competition.
Thank you guys for discussing my work. You created a huge traffic peak on my blog! I had to search a bit to find where it did come from as HN's links apparently aren't tracked by WordPress statistics (rel="nofollow" I guess)

My answers to some of your questions:

Yes, my own images are free ( https://en.wikipedia.org/wiki/File:Shaftpasser1.jpg and https://en.wikipedia.org/wiki/File:Shaftpasser2.jpg ) . The scan from the mine cable was sent to me by email but I don't know its exact reference and status

Clearly the wheel would be extremely difficult to produce and to operate, especially if torque has to be transmitted. I intended to model a version with the german cable design, i.e. one of the half-spoke attached to the star wheel axle, but I leave this to the most fanatic of you ;-)

Congrats to ambrop7 for the printable model !

Ummm.... I couldn't see that video (restrictions on work internet) but AFAIK such small drones can fly up to a certain altitude. Sure you have an insanely large amount of sky up their but can these machines access that?
Kotlin is not much simpler than Scala. It implements some of the Scala features in actually more complex and IMHO less elegant way,(pattern matching, null safety), copies some 1:1 (declaration site variance) and leaves out some of the most powerful ones (implicits, dependent types). I personally don't buy it. I like languages which offer few, but very general and powerful features / abstractions, than languages that concentrate on directly supporting special cases.
This article focuses on financial reasons not to trade - but there is also an ethical concern.

The stock market is a zero sum game - for every buyer, there should be a seller (whether it's another punter or a broker). for every win, there is a corresponding loss.

As such, the stock market (trading on companies already invested in) is 100% unproductive - it's not doing any useful work (except valuing stocks, if that's useful.)

Therefore, if you want to contribute to humanity, if you want to feel like your job actually accomplishes something, you are literally better off as a Barista at Starbucks, like my 17 year old self, than trading stocks.

The stock market drains too many clever brains from other real industries - it is a tragedy. Think what we could accomplish if return actually reflected value added/economic utility!

I think there are a few opportunities to make money in the market that don't violate the weak efficient market hypothesis. I look for opportunities where there's too much money or market sentiment for Wall Street traders to make things efficient, so the EMH doesn't strictly apply:

1) Index market timing. This is easy: allocate your funds among multiple indices Boglehead style, and if an index's P/E is too big, divest from it. This strategy beats the market with almost zero effort. There's tens of trillions of dollars of market cap out there, there's not enough money on Wall Street to reverse the polarity of that.

2) Large stocks subject to large negative sentiment. AAPL when it was at $400, BP, etc.

3) Large stocks subject to large, wildly varying market sentiment, like TSLA. I'm a little afraid to try this with real money, but have been paper trading it with success. You have to have a good mental model of how mass psychology works, and it's easy to get that wrong and lose a lot of $$$.
Are there tools to find out about tech companies that have recently IPO'ed? I'm not talking about the most popular ones like FB, Twitter, etc, that the whole press is talking about, but lesser known ones. Or are tech IPO's so rare, that they all pretty much show up on Techcrunch and the like?
The first electric installations and equipment were relatively dangerous actually. No good isolation of metal parts, no separate earth wire, metal body, etc. Things like hair driers were often electrocuting people.

Even the improvements took a long time to become popular. I remember some electric tools from 80s that were known to zap people from time to time, but "that's just the way they are". So yeah... I suppose that the first people to adopt electricity at their homes actually did have something to worry about.
Once autonomous cars have saturated the marketplace, I can only think of two reasons to still drive manually:

1. As with people who row or sail, just for the enjoyment. Such usage could be restricted to specific places like racetracks.

2. Because I'm going somewhere I "shouldn't" and I don't want to tell my car (and have it record my journey for someone else to review, or refuse to take me). This may also be the case with emergency vehicles, an ambulance may need to drive along a pedestrian-only street, for example.

Now, there will be a need to mix human vs autonomous traffic on the run-up to that. Obviously, until sufficiently many cars are autonomous to warrant the removal of human-controlled cars, that will need to be the case. Furthermore, early production Autonomous cars may have routefinding flaws, or the computer may break down, meaning that someone may need to drive a normally autonomous car themselves.

Yeah they can make use of the model employed by tesco in South Korea[1]. Instead of trips to the grocery store, you can just tell amazon to deliver to your place. Ran out of batteries for your remote? Amazon! Heck, Amazon Book store would benefit LOADS from this. So yes, not only does this open up new markets, it also improves their existing businesses as well. No one likes to wait. And they could cash in on that! (Not to mention it would be pretty cool receiving stuff by drones) :P

Actually the real "main reason" we have patents (in the US) is to avoid people not sharing trade secrets, which was a real problem with industry in the 1700s but is not one now.

The justification for them being a way to ensure the "inventor" is compensated came much later and Thomas Jefferson would likely be spinning in his grave if he knew how they were used now.
> I've been beating the market, albeit by only a few percent, for years. I may just be lucky, but I believe my methods give me an edge.

The problem is that for an outsider to whom you are a stranger, the former is overwhelmingly more likely than the latter.

Scala doesn't make a distinction between operators and methods, and Java has always supported unicode in method names, so they have to be possible for compatibility if nothing else. I think if used carefully, with discipline, they can make code more readable and ultimately more maintainable - e.g. for doing set algebra it's nice to be able to have ∪ and ∩ methods. But yes, if you want to shoot yourself in the foot with them it's very easy.
This thread inspired me to write my thoughts down: http://jaekwon.wordpress.com/2013/12/02/the-supernova-theory...
I think a blend of your advice and that of the original post is correct.

I agree that the Efficient Market Hypothesis is a load of rubbish repeatedly disproved by the movements of the markets not to mention the impossibility of the assumptions on which it relies (perfect information etc.). However if you are investing from a position of ignorance or sentiment (rather than on the Intelligent Investor basis) then the EMH may as well be true. It is only worth trading when you believe that you have an advantage from such proper analysis. For most people this is pretty much never - which is where the original poster's advice comes in.

So if you do have valuable industry knowledge and the time to glance at the basic company figures OR time to fully analyse the fundamentals of companies in the Intelligent Investor style go ahead you may well come out ahead but do remember that the market can know something you don't and/or remain irrational so you need fairly long time horizons.

My summary is if you have an advantage use it, if not then use index funds.
Maybe you should first learn the language? It would save your time, really. You must know the language to understand programs in that language. Simple as that.

If you don't want to learn FP or you don't value type-safety, Scala is simply not for you.

Kotlin hasn't even been released yet, and it looks just like Scala.
Battery density is not that much of a problem. Supply from warehouse to moving warehouse vehicle (truck?) to multiple delivery vehicles (drones). Parallellise and automate the last mile.
>There are a few traders in history that beat the market in a statistically significant way for basically their entire career.

Given the vast number of market players, what counts as "statistically significant"? A probability of seeing results at least as good as theirs by chance of 1 in 20? 1 in 100? 1 in 1000? 1 in 10,000?
Great idea, for small items. A few other companies are exploring this, but with the funding from Amazon, and the scale Amazon delivers at, it could make a lot of sense for them - they could actually make this a reality. I'd try this out just to see the Octocopter coming in to land.

Weight will be a problem I guess, as many of the things Amazon delivers are larger and would be difficult to carry on a drone unless it was a significant size. So small items only, at least initially.

I did also wonder about landing spots - these things are going to need a guaranteed flat spot to land, so that they are not damaged and can take off again, but I guess with a smartphone the user could indicate their preferred landing spot via GPS.

And of course there is an issue with airspace and regulation, which I guess will be their biggest hurdle - flight paths over cities could get pretty busy quite quickly, and you'd need some sort of one way system or sophisticated traffic control to avoid collisions, so a bit of a headache for authorities to coordinate, but these are all soluble problems.
It looks like the last commit was a couple of years back so this isn't very new, though I hadn't seen it before and it's very impressive.

Bullshit, dude. You are being a coward.

Does Rome or France conquering England have an effect on the way we should manage global emissions policy or not? Because if it doesn't, why are you mentioning it?

Do the different circumstances that India has during industrialization mean they should take a greater role in limiting their emissions or not? Because you mentioned just two items, medicine and technology, which are both positive. And you didn't indicate how they relate to emissions.

Instead of slipping in minor irrelevant facts that betray your bias, just state your opinion.

Your article is great btw, v. good points.

I'll bet this story is common.
I would rather use almost anything else except the random DSL wasteland that is Scala

In my experience very little Scala code uses DSLs. Learning Scala isn't that tricky for anyone who knows Java, which is a pretty big pool.
It's worth noting that that Warren Buffet quote was from an annual letter written in 1988. The retail investing landscape was very different then than now. For quite some time, Buffet has been a strong proponent of index investing. Here's one from that same annual letter, in 1996:

Most investors, both institutional and individual, will find that the best way to own common stocks is through an index fund that charges minimal fees. Those following this path are sure to beat the net results (after fees and expense) delivered by the great majority of investment professionals. Seriously, costs matter.

True, he doesn't say you can't beat the market. But he does say, then and now, that you probably shouldn't bother trying.

Plus, say through in-depth research and know-how, you do manage to beat the market. At best, you've created a part-time job for yourself. Unless you're managing other people's money, or have a 7-figure+ portfolio, I expect the time taken to do the due diligence necessary to consistently beat the market - if indeed such a thing is possible - would end up paying a lower hourly rate than you could earn doing other, more reliable, less zero-sum things.

Personally,

-General device testing is well served at SmallNetBuilder (the octoBox test environment used now is awesome), though the stock FW is obviously tested more often than not

-Ubiquiti gear is indeed pretty rad

-Old Broadcom-based gear is still holding up well for low throughput use using Tomato + variants (.. or even DD-WRT)

-I would probably avoid 11ac models for now (unless you have a compelling reason not to).. but if you do decide to go that route, the BCM470(8/9)x SoCs are Cortex-A9 based [versus the single-core MIPS based BCM4706]

An OLED screen will deliver that (pure black and sub-ms response time). And they are on sale now as televisions (albeit at scary prices along the lines of US$13000 for a 55" screen). 4k OLED screens with a 55" diagonal have also been demonstrated. From the sounds of things, new manufacturing techniques are being developed that will bring the prices down to sensible levels.

Here's a review of one of the screens currently on the market: http://www.digitalversus.com/tv-television/lg-55ea980w-p1619...

Guys-

Since super saver shipping worked so well, we decided to further expand our delivery options by offering instantaneous delivery. Since quantum teleportation is still in its infancy as a technology, the best alternative seems to be orbital fulfilment centers with ballistic delivery systems. So far, we've successfully built a prototype magnetic railgun that serves most of the western United States. While it does deliver items within seconds, as planned, we have not worked out all of the kinks (not to mention the, ahem, liability issues.)

We have been pursuing a partnership with some contacts Jeff made in the course of his space exploration work. The technology transfer is promising but the long term ramifications are unclear.

In case what amounts to the militarization of e-commerce becomes impractical, we've also been pursuing a more conventional method for rapid distribution in desnely populated urban areas. You can go take a look at the prototype on the top floor of PAC (you'll need your "special-access" key, though.)

Since you're focused on blogging and not about managing your blog I suggest you go for self hosted WordPress. Find a clean fast loading theme and you're good to go.

Then add some nice articles showcasing your expertise. Add an about me section, preferably in top of the sidebar so it's visible to anyone. This is a great place to summarize your technical skills.

If you want to engage with fellow Ruby developers then I suggest you join a community. When it comes to visibility a Google+ community is a good place to join.

Your site can attract better job opportunities if you write enough and provide value. But you'll have a better chance with a good LinkedIn profile. I know few job hunters and they almost always look in LinkedIn first.

Good Luck :-).
