The point is that you probably can't do it repeatedly, or predict with any confidence that you can even do it once. Numerai enables you to bet using someone else's money, with a vastly reduced reward, but no risk to you.

Numerai won this time (hence the PR piece) but I don't think we should judge their performance on one action in isolation. We should judge whether their approach works based on a year or two of trading on these predictions. Maybe longer, if reacting to unusual events (economic collapse, freak speculation on tulips, etc) is something you care about.
It still has firmware, of course, which cannot be audited -- which makes it exactly as secure as a $40 Yubikey. Perhaps even a little more secure - because a Yubikey is vulnerable to both Yubico and NXP employees, and U2Fzero is only vulnerable to Atmel. [Both, of course, 3 letter agencies]

Is there a similar chip with Curve25519?
>>My point is that "Engineer" (software or otherwise) is a legally protected term in many countries (Canada, Switzerland,...)

Actually, you're looking for the term "Professional Engineer" which can only be legally used if you have at least a B.S. or B.Eng. (or local equivalent) in an accredited program, have taken some kind of certifying exam, and may also require a certain number of years working in the field to obtain licensure. In the US, there is a PE certifying exam for ABET accredited Computer Science and Software Engineering program graduates.

Your Wikipedia link had no information about Switzerland, but it did have this interesting bit about the Czech Republic: "In the Czech Republic, the title "engineer" (Ing.) is given to people with a (masters) degree in chemistry, technology or economics for historical and traditional reasons." Every country is different...
For a start, I'm going to hazard a guess that you have never sent money to family overseas.

With bitcoin you can transfer money internationally for cents and in seconds.
I know this was meant as a joke, but with touch ID, you can have up to 10 different "passwords", or 11 if you're the bane of Inigo Montoya. You could technically have ten more than that, but most people don't like having to remove their shoes to login.

It's still not as good as the nearly infinite number of potential passwords, but it's not like there's only a single possible fingerprint for you to use.
Subtract 588 million reserved IPs, as well as 2 from each subnet (0 and 255). There are also a lot of blocks that are publicly routable but see no use on the internet. If I were to build a rainbow table, I'd start with blocks assigned to ISPs, then throw in the results of publicly available distributed internet surveys, only then would I start the algorithmic address generation. Same story for IPv6. I really don't think it is a state actor level problem, but if it is it won't be for long.
Gee, I wonder if it has anything to do with cell phones, and in particular, the high bandwidth data consumption of smart phones.

Look toward a city skyline at night. Or even a small town. You'll see a blended haze of light reaching up into the sky. Probably a similar deal with the general radio spectrum emissions, now that everyone's carrying the equivalent of pocket RF flash lights, and walking in proximity to the RF street lamps that cell phone towers have become.
In this video[1] Varoufakis takes on modern economics and their models as a way of understanding the real world and predict what's going to happen.

On a higher level, I believe that he speaks for most (if not all) social sciences and what happens when they cross mathematical models who blindly try to understand and predict the real world through a flawed, limited mathematical model.

A very interesting argument that numerous changes over the last several decades, intended to make government more transparent and less corrupt, have made it very difficult to get anything done at all, and additionally have increased the likelihood of electing fringe candidates.
I agree. I wouldn't do that either.
Amazon has spent years screwing with Amazon Prime video subscribers on Android to the detriment of the Prime brand and their brand as a whole in the eyes of many of those affected users. Amazon could very well screw with AWS to the benefit of Android Prime video for reasons only upper management can discern.

Ask HN: Is the “beer test” relevant in choosing investors?
Presumably the "beer test" (Would I like to have a beer with this person?) is somewhat relevant in selecting anyone you'll have an ongoing relationship with. But it seems like it would be a significantly less useful heuristic for selecting investors than for choosing cofounders or employees (the context in which it is most commonly referenced).

Are there any better heuristics out there for evaluating investors?
Is historical data necessary when you can just compare urban to suburban to rural areas?

This is a bad idea.

Wind and solar are simply not enough to bridge the gap between fossil fuels and fusion.[0] Shutting down the country's safest, cheapest, and most consistent method of power generation would be disastrous.

Four scientists who have played a key role in alerting the public to the dangers of climate change sent letters Sunday to leading environmental groups and politicians around the world. The letter... urges a crucial discussion on the role of nuclear power in fighting climate change.

Environmentalists agree that global warming is a threat to ecosystems and humans, but many oppose nuclear power and believe that new forms of renewable energy will be able to power the world within the next few decades.

That isn't realistic, the letter said.

"Those energy sources cannot scale up fast enough" to deliver the amount of cheap and reliable power the world needs, and "with the planet warming and carbon dioxide emissions rising faster than ever, we cannot afford to turn away from any technology" that has the potential to reduce greenhouse gases.
The letter signers are James Hansen, a former top NASA scientist; Ken Caldeira, of the Carnegie Institution; Kerry Emanuel, of the Massachusetts Institute of Technology; and Tom Wigley, of the University of Adelaide in Australia.

Lavabit's shutdown revealed the flaw in its premise. That encryption-at-rest was good enough for email security (while using a single TLS key for all in-flight data). Turns out it's not. Only end-to-end encryption—with keys only held by the end-users—can provide that. As despicable as FBI's actions in that case may be, they did the public a service by showing Lavabit's security proposition to be less than what users may have assumed.

EDIT: Nothing I wrote above detracts from your point, though. Re-enforces it, in fact. Lavabit held little or no data, which caused the FBI to escalate to the nuclear give-us-your-master-key option.

There is an existing partnership where SolarCity sells and installs Tesla batteries.

I think Tesla's ability to sell another company's installations is limited by the impression they are trading on their brand. ie. a "Trump Steaks" problem.
Math please? There is enough wind and solar potential in the United States to meet our energy needs several times over, even when including moving all light vehicles to electric.
This is the last state you want to shut these reactors down in. California has mountains of regulations that only apply to new things. Many (most?) buildings that exist today could never be built because of some violation.

Once these plants shut down they will never be reopened.

Do you think people with different sexual preference than you also "should still at least try alternatives when they are presented"? When it comes to something as personal as putting food in their own body for their own nutrition and enjoyment, nobody should do anything just because you think so.
That even with the current plants in operation for over 40 years, surely having their capital costs paid for, they can't compete against the economics of wind and natural gas (which is pushing current plants into early decommissioning).
Most applications branch based upon their state. You can't just statically analyze them without knowing that state. OK, so you can add print statements to get a small peek into the state. But if you have a moderately complex application with multiple branches, you'll need to keep adding these to even know where to point your next print statement. That's a rather tedious feedback loop.

Functional programming does make your code more statically understandable, but it's not going to remove branching. So I guess you memorize all the inputs? Do you write them down? Might be easy if you have a simple program under your own control, but not when business requirements impose a wide array of inputs, and some of those inputs are different than you expect (hence, the bug).

It's also enjoyable to drop into a REPL (read-evaluate-print-loop) at some interesting point. At that point you can try all sorts of things with no friction. Minimize your feedback loop.

It's funny how Lisp was famous for its REPL, and yet now we're in the 21st century and some people think they're too cool to use a REPL.

As for me, I'm enjoying Redux style time-traveling debuggers... in the future rather than tedious print->run or step slowly we may just query the state of a program over time like a database.

This is likely content coming down from an HTTP API so likely already gzipped. Since you can gzip both CSJ and JSON I think that's not really relevant.

With this proposed format you only need to parse the object definition once and you also get the ordering fixed. From then on you need only validate each field in each line as being legal and you can build your object quite fast.

This format saves probably half the network bandwidth, half or more in memory requirements, and more than half the cpu complexity in parsing and getting your final objects instantiated. That's pretty good.

Remember the goal isn't to replace JSON. It's to replace CSV. JSON and CSV have different goals. This is simply a JSON structure built to meet the same goals as CSV. It seems to do that quite nicely and can use existing JSON parsers internally to do it. Pretty nifty.
Yes and No. I don't subscribe to the fact that you have to be drinking buddies with your investor, but at the same time, if you can have that relationship then that is awesome.

What is important is that you and any investor you are talking to see the future and your business in a similar way and that you feel they are a positive impact on you, your business and can bring you at least 1 or 2 additional things other then money. If they only thing the investor brings is liquidity, walk away as it won't be a positive relationship in the end.

Even non-radio devices like lighting ballasts, solar panel charge controllers, inverters, etc can cause lots of noise.
That's a good idea. I don't think it would be hard, you just get the interpreter to run in a loop and read from the keyboard input. I'll put that on the list for upcoming features :-)
How about twice the bandwidth, twice the memory, and at least twice the CPU complexity in parson full JSON objects than the proposed CSJ format?

Maybe we can talk about ways context should be changed?

I still don't walk into a store with my phone and then quickly walk out with exactly those items I predetermined. Occasionally I will use my phone as a list, but a small piece of paper is easier to reference while in the store. I don't ever see anyone else doing any better and most never use their phone or any other device.

I think this means that we do not yet have true personal computers.

What might be the most important context to change/solve?
In a half century there was ~4 major meltdowns in the world that affect people lives:
1) Kyshtym disaster (57')[1] - it was old production site after WWII - will never be again
2) Chernobyl (86') - stress-testing nuclear plant and disabling all levels of protection - will never be again
3) Fukushima Daiichi (11') - Obsolete block not stopped

Other disasters are not affected anyone outside of the plant, for example Three Mile Island. And that's all! On the other side, hydro plants actually make things much worse to a nature and already killed big rivers in siberia. Fossil-fuel stations (67% of worldwide energy) are even worse.

Nuclear plants are still the safest for environment and the only way to bring electricity to developing world because it can be very cheap. Take a look at B. Gates nuclear reactor: http://terrapower.com/pages/technology

Building some nuclear plants will be able to feed anyone almost forever. Unlike solar energy that you need to keep in batteries for the night. And who say that batteries can't explode? It is looks like fear of flighting: no reason to fear planes and much much more people die in car accidents that in plane one. Same here - much more people die from other sources that from nuclear plant disaster.

If any Instagram people are reading this, please for the love of all that is sane, please I beg you add some kind of progress indicator for your API.

3 weeks in, I find myself loading my app's API client page to see if it's still stuck in a greyed out "go live" mode.

I've got an "Instagram API" search saved for twitter and StackOverflow to check checking if anyone else gets to slip through but others struggle just as much.

Just a little transparency and predictability is all that we ask for.
You gzip csv and csj as well so this is orthogonal to the point.
There are many fewer weapons available for an impromptu nuclear war, and despite the horror that I think many readers here underestimate, that reduction is a Very Good Thing. The problem is that the nuclear explosives may have been taken apart to some extent, but they can also be put back together.

The nuclear arsenal is predominantly hydrogen bombs, and they are insanely powerful. The Hiroshima bomb was 16 kilotons. A W-87 and W88 warheads are a bit under half a megaton, or roughly 30X more powerful. The W-78 is about 350kilotons, about 20X larger. The B-83 bomb lets you dial in just how spectacular you want a return to neolithic life to be, all the way up to 1.2 megatons, about 70X larger than the Hiroshima bomb. There are fewer than 250 cities with over 1M population. With just the ready US arsenal you could blanket most of the populated parts of the planet.

In 1967 the US maintained an arsenal of about 30,000 (!!!!!) nuclear weapons. You have to wonder. Now the stockpile is about 4500 and about 1500 are deployed and ready at a moment's notice.
Yeah right, "in the field". Nowadays you can do old-style animal farming if you have three cows and want to sustain you own family. Otherwise, if you want to sell it, it's just not cost effective.

agree with what your saying and these burgers would probably sell fine if they didn't get labeled as vegan. but yeah there must be a specific market that does want this, because we've been seeing fake meats for years.

personally I'm in a different camp. I've been vegan for a while now. I pretty much never buy fake meat or fake cheese. I don't really understand it. I just eat food I make from the bulk section of the grocery store. I don't see a need to have a "boody plant burger that smells like meat" or a boca burger, that just tastes like a...boca burger. honestly I rather just have a patty made out of blackbeans and lentils that doesn't taste anything like meat. seems way simpler to me.

Like the RIAA? No thank you, I'd rather keep those powers in government's hands.
Yeah, the park analogy kind of breaks down a bit with radio, but the point is, ham radio is not for the people that want to discreetly pass coded messages on slips of paper to another person in the park. It's a medium for the guy with the megaphone telling people to evacuate due to imminent threats.

In any case, it's the same argument for not allowing automobiles on walking paths: sure, it'd probably work, but it sort of takes the fun and utility out of it for other people. Encrypted messages converted to sound for transmission over the air sounds horrible, and for somebody that's scanning through the band, landing on that monstrosity is very unpleasant. Also,if you are transmitting encrypted traffic, you are by definition doing so at the exclusion of every other ham; they can't know what you're transmitting, and they can't transmit there. Plus, ham bands are 100% noncommercial, so there's also no way to enforce that rule.

The purpose of the ham bands is not for you to pass your tinfoil wrapped messages to other similarly paranoid people. If you want that, use unlicensed spectrum. You can pass whatever kind of traffic you want there, assuming you're not causing interference.
I think most of the losses are due to the cost of building and maintaining transmission lines. These have to be paid for by users of the power grid. In Germany these transmission costs constitute about 20% of the total end-user price per kWH (i.e. about 5 cent/kWh).

Well, it's explained in Methods, but over my head. I gather that instead of just looking at correlation between X and Y, they first map X to a ‘shadow attractor manifold’. Then they fit a relationship between this transformed X and Y.

They cite Sugihara, G. et al. Detecting causality in complex ecosystems. Science 338, 496–500 (2012) for this.
Because to parse it legally you'd have to store the entire file in memory. That's not actually streaming. The CSJ format puts the object schema and order up front and just applies it to each line afterwards. Stream away...
just randomly looking at it.... http://cgi.di.uoa.gr/~mema/courses/mde518/papers/ousterhout-... seems like it's far too opinionated rather than educational, should keep to the job of explaining the problems of threads, not to put people off them by saying they are bad. That kind of thing can end up being burnt into a students mind. Better to promote other solutions, like abstractions over concurrency or languages with better abstractions. I'd hate to think we are training people to avoid concurrency when we are getting more and more multi processor systems

The FCC's mandate isn't to stop everyone everywhere in the world from producing crap $5 baby monitors that spew noise on the whole spectrum. Their mandate is to keep those crap baby monitors out of the US and off US markets. Which they can do relatively easily; even if the manufacturer is hiding behind seven proxies, twelve shell companies and sourcing from two dozen countries, those baby monitors still had to get into the US at a particular port of entry, had to be sold by someone who had the ability to take payments from and arrange delivery to people in the US, etc., and that's going to point to someone the FCC can happily issue big fines to, discouraging them from continuing to import/sell the devices.
