If we're going to project out into the future, then driverless cars promise to be a game changer. Granted, we're talking twenty or thirty years out rather than ten years. Driverless cars can facilitate more single family detached houses without the sprawling roads and parking lots. With any transformative technology, it's hard to predict how things will work out, but driverless cars could, ironically lead to more walking.
What sort of work are you referring to when you say it's a lot to keep up?

We've been using OpenTSDB here in an extremely high traffic setup for about a year now, with absolutely no issues at all. It took a few hours at most to setup and figure out scaling.
Thanks for the extensive summary. It all sounds pretty circumstantial, but it is a lot of stuff when put together. I guess the real question is, assuming it's real (and you have me reasonably well convinced), is this a major "ship in five years" product push, or a just-in-case research project?
First and second one are both good. I saved first for future discussions. Appreciate it. :)
I'm not implying that they were holding back on purpose, but I did not expect the quality of the whole streaming event to go up so highly. It feels different than before.
Maybe not rich but a lot of the lower income people in my neighborhood in Brooklyn aren't using Uber or Lyft regardless of how cheap because they don't have much money period. You have to have a phone and internet access for these services so it's definitely not hitting the lowest brackets.
There doesn't seem much of a trend in that direction. Most city office jobs could be done remotely but there are advantages to being central. You can meet people, go to conferences, chat over coffee and the like. It's kind of ironic in a way - you might have thought being able to work form a laptop would lead to people spreading out but it seems to lead more to people thinking they may as well bring the laptop to a cafe or office in central SF, London, NYC or the like.
Sure, Bezos gets the "first rocket that went to 'space' and landed vertically" prize. It might even be cool sounding for the laypeople who really don't know what values 'space' can take.

But it's not what matters, in fact it's irrelevant, was not a disputed trophy, and won't be mentioned 50 years from now.
And now a single company can. Progress!
You might think differently if you were responsible for those children. Do you want to take the risk that it might be a real threat? How do you tell the difference between a real threat and one that isn't real? I'm guessing the people at the school district thought the small risk wasn't worth it, and decided to close the schools. Who would want to be labelled as the person who didn't close the schools if someone ended up getting killed? Even if the threat seems implausible, it must be a very difficult decision to make. There have been many bomb threats recently, probably mostly implausible, but for every one of them the airline acts as if it might be a real threat.
They actually used to be near that, but the accident grounded them for half a year.

Ultimately they're limited by available manpower and production capacity.
That would only make sense if you could somehow rent 51% of the hashrate, which isn't remotely true.
I had to stay longer at work and was late to the event. My first question, even as the YouTube link loaded, was... "Did they land it yet?", followed by "When are they landing?". Lo and behold, a nice progress bar saying - grab your popcorn, we're about to land now!
Ok, in that case, SpaceX was 'first' to land a VTOL rocket with Grasshopper... unless you want to invent an extra category of "first VTOL landing for a ground launched rocket that crossed an arbitrary altitude threshold before returning at terminal velocity".
And with the amount of redundancy built in they might even go with 'acceptable loss' in terms of engines that cut out early in flight. Which makes you wonder how many engines they could lose and still complete a mission.
so its like http://sdr.osmocom.org/trac/wiki/fosphor but limited to audio?
The philosophy went farther than, "We want GCC plugins to be free." It went to, "We want GCC plugins to be basically impossible, because otherwise the risk of non-free plugins is too high."

So, the FSF sacrificed technical needs in order to serve philosophical goals.
That seemed to be the implication.
I think SpaceX is sufficiently motivated by their man at the top that they'll keep doing great things even in the total absence of competition. But it would still be great to see others go this way, to see different approaches tried and such. It sounds like some other launchers were looking at reusability plans before (Ariane had plans for some wacky thing that would fly back just the engines) but now that it's been demonstrated to work I imagine it will become much more serious.
Respectfully, I don't think this puts this project outside the scope of any other static site generators as listed.

In my view a content only API would be more disruptive. A smart content API as a service could be used for any project. Give it a beautiful interface for authors and focus on the writing experience.

Maybe this is Mediums potential new market/ platform. What if you could grab and query your content with a smart api with graphql? No updates, servers, etc.

Any new project I used, I grab my content from this saas and use whatever tech/framework I want. Why aren't more devs looking at this as an option going forward?
Url changed from http://www.theverge.com/2015/12/21/10641600/ces-2016-google-..., which points to this.
Why is that so many of the newer languages put the type after the name? I know it's just something to get used to but it feels clunkier to me. At first glance this looks like the 1 is getting assigned to Int:

var i: Int = 1

If Gruber wrote this, it might actually get traction at Apple.

There does - in fact, there exists every single percentage of difference between servers-in-bedroom to full-Azure/AWS. We run full AWS. The company one floor up runs their own OpenStack private cloud on colocated servers in a Level 3 facility. Want to rent and not own? You can have that, too. Softlayer is somewhere in-between there.

There exists just about every price point and combination of services you can imagine. It's awesome, too, because I can grow a business and can enter into the market with a whole "rack" of servers for almost no cost at all.
The best way to think about the mining market is that the number of Bitcoins available to be mined each day is _constant_* no matter what the total hashing power deployed is. As a miner your share of that fixed pool of available coins is determined by your hashing power relative to the overall hashing power of all miners. So if you control 30% of the hashing power you should on average get 30% of the coins mined each day. Your profits are then determined by your costs and the value of a bitcoin when converted to the currency your costs are denominated in.

* The constant amount actually changes periodically when the coinbase reward is adjusted downward but that only happens about once every 4 years and historically exchange rate price appreciation has outstripped the reduced coinbase mining rewards. eventually the coinbase reward will go to zero and the number of coins that go to miners each day will be their relative share of the total fees being paid by users transacting on the network. Miners choose which transactions to include in a mined block so in the future a large miner may have some pricing power over transactions because they could refuse to process any transaction with a fee that falls below some threshold.

The hydrogen in the Space Shuttle Main Engine creates embrittlement in the alloys of the engine. [1][2] The launch sequence also involved running the engines at 104.5% of rated capacity. [3] Before Block II of the engines, the turbopumps needed to be disassembled and rebuilt between flights. [4]

I have no real idea how significant coking of the Merlin engine is, but the SSMEs were hardly "clean".

Ask HN: Best way to sell domain names?
Hi all,

I've accumulated some domain names over the last two years for projects that I started, but never got off the ground.

Instead of just letting the domains expire, what is the best way to sell them (and at least recover some of the cost of having them)?

Doing a search for domain valuations and auction sites comes up with plenty of hits, but if I'm only going to do this once, it would be nice to do it right.

What are my fellow HNers preferred ways of dealing with unused domain names?

Thank you, as always, for your advice :)
This is so off-topic it's painful, and inflammatory to the point of absurd. Please don't create accounts on HN to conduct political/religious/ideological flamewars.

Like precious metals? Deflationary currencies have been used successfully for over 1000 years.

The only people it is bad for are governments. Throughout history there is a patter of promising, spending, and becoming insolvent.

The idea that an individual wouldn't choose a deflationary currency is ludicrous. Inflationary currencies are what you want everyone else to use.

And by the way, the cat is out of the bag. Cryptocurrencies are here, bitcoin or not. When people can choose to use any currency they want, will they choose one that inflates? I doubt it.

Even a small difference in orbits adds up over time. You don't need much fuel for orbital adjustments, as long as you're staying in the same plane.

Say one satellite's orbit is a bit smaller. That means that, over time, they will naturally drift farther and farther apart, until they end up on different sides of the globe. At that point, just raise the smaller orbit slightly.

Kerbal Space Program is really good for understanding stuff like this.

It probably is closer to destroy rather than transfer. Yes there will be a shift of capital from investors pockets (pension funds ultimately) to drivers and consumers, but a lot of this capital will be squandered on drivers driving at less than full capacity and consumers not paying the true economic price. Neither of these is a very productive use of capital - there is of course the environmental cost of half-empty cars driving around too.
Sorry about that. I missed the other discussions. I am pretty pumped to give this a spin.

This is the most logical way to add optional typing:

var i = 1 //Type inference
var i:Int = 1 //Explicit type

i.e allowing you to optionally enhance existing code with explicit type info without changing the existing definition.
SpaceX Completes a Vertical Landing at Cape Canaveral
The syntax of any programming language is easier to grok because it is more concrete - not because it is more complete. It is not so much that "math is stuck using punch cards", but rather that you only really need as much formality as it takes to express the central idea - which is far short of what would be required for a concrete implementation.

They do. Natural Gas fueled generators are practical at 50MW capacity. GE basically sells a 747 engine (CF6) driving a generator, known as the LMS6000

It's more like seizing the customer records from Cock Postal Service (presumably operated by James May).

My guess is that the fact this guy ran the operation from his bedroom, and they weren't sure whether he would co-operate or not, was the reason they seized the disk rather than just subpoena him. Presumably if it was hotmail or gmail this wouldn't have happened.

I think it's good that this scumbag cocksucker is going to get his commuppence (I'm talking about the idiot who sent the email, not the guy who runs the cock email service). He's obviously a bit of an idiot to use an email service that says "will report any illegal activity to the relevant authorities" rather than one that is actually properly encrypted (if such a beast even exists at the moment -- they seem to all get DDoSed out of existence by China or similar pretty quickly).
>most of the power consumed by the traditional financial system is spent in its capacity as a ubiquitous pillar of modern society

Either I missed your point or it would be nice if you brought this back down to Earth. Yes, traditional ledgers help mediate economic exchanges. Bitcoin, as a ledger system, also helps mediate economic exchanges.

> ... wherein bitcoin would be completely subsumed were it to become anything more than a technical novelty.

You put this forward like we should all nod and say of course. Care to tell us about this scenario?
Once the 16nm chips become a commodity, it will make sense that the hashing power would get more distributed.

I hope figures out how to get a solar powered, interchangeable bitcoin miner in a box at a positive ROI. It may seem impossible now, but solar prices are falling faster than expected.
Anywhere in the USA who has to pay USA power prices is going to be at a disadvantage by that alone then. It would seem that locating the hashing equipment to the place with the cheapest power possible would be a logical step when things start to get cut that fine. Unless that could be overcome with clever usage of naturally generated local power (such as solar power).
Could be a figment of my imagination - a normal flaring of the rocket flame + a light.
It might seem mildly useful until you realize why bitcoin, gold, or fiat currencies all have value - their properties lining up with the properties of ideal money. Gold is not valuable because of jewlery or industrial uses. It is valuable because it was the original decentralized shared ledger. Easy to verify, easy to divide, hard to create, hard to destroy (and some more if you look it up).
In the video of the fairing adapter deploying the satellites, there's some kind of white highlight or light-source in the upper-left part of the frame. What was that?

Also, what happens to the mass-adapter (i.e. the balancing 12th non-satellite)?
tdlr - "Scientists have developed an easy-to-use computer program that can quickly analyse bacterial DNA from a patient's infection and predict which antibiotics will work, and which will fail due to drug resistance."
Depends on the bug, it could be that it's only triggered as a result of the compiler getting in a certain state by processing a bunch of code leading up to the problem area.
So, no true Scotsman?

This DC cost $100 million. Not exactly pocket change. http://www.coindesk.com/bitfury-details-100-million-georgia-...

Plus, with BitFury online, the cost of a 51% attack just raised to $200 million.

The only reason it is (currently, for a short time) hypothetically possible to 51%-attack the network with a budget in the low hundreds of million of dollars is because most of the miners are not using such efficient 16 nm chips. As the market migrate to these last generation chips, expect the cost to increase to $1+ billion in the next year.
Or buildings like Google is building in London http://www.dailymail.co.uk/news/article-2950181/Google-scrap...
It's not necessarily 'irrational'. A 51% miner could profit from Bitcoin's downfall, or by threatening others, or even by bluffing an attack. See, e.g., the Goldfinger Attack in https://www.cs.princeton.edu/~kroll/papers/weis13_bitcoin.pd....
Agreed... lets keep it in terms we all understand and that make sense...

Here's a worst case test image for chroma subsampling:

https://commons.wikimedia.org/wiki/File%3ARicardo_Quaresma_%...

I first saw this in Fabrice Bellard's BPG demonstration at http://xooyoozoo.github.io/yolo-octo-bugfixes/ ("Soccer Players"). Every lossy format fails to reproduce the red dots on the green stripe because they all use chroma subsampling. Until I see tools that can automatically deal with images like this I think the anti-subsampling attitude mentioned in the article is correct. "Unless you are willing to evaluate each image, the thinking goes, you should avoid subsampling."
We use a old traffic signal powered by a Raspberry Pi to similar effect. We have found it quite useful in providing timely feedback and encouraging the quick resolution of issues.

You can see pictures and source: https://github.com/tantalic/build-light
A real bad thing here is the asymmetry. To prevent 51%, the network has to burn enormous amounts of energy 24x7 forever while the attacker only needs his energy for the duration of the attack.
Stupid question: if control of 50% of the hash power is so unimportant, why does Bitcoin rely on hash power anyway? Why not simply have a consensus system without proof-of-anything?
I never advocated not using Facebook as if I'm above it. I'm questioning regular usage of social media... obviously not everyone (incl. you) falls into these categories, but can you imagine the great minds and innovators of our generation regularly Tweeting, engaging Instagram followers, and constantly updating their FB (if not for brand/ PR)?
From p.65:

> Overall, resilient public cyber key terrain could prove a double-edged sword: enabling DoD to project power, both in terms of information as well as cyberspace operations, but also enabling enemies of the United States to do the same, and with a lower barrier of entry than before.

I think you could argue this is a bit what the government already thinks of the Tor Project, although they call it 'loosely decentralized'.

I seriously whether or not politically we will actually head down this path; which each successive government I'm beginning to see the fear that cypherpunk-utopia, anarchocapitalist-style decentralization may bring to nation-states and the risks inherent to some citizens in that process.

From a politician's (very misguided) view of laws solving problems, it's easy to smash the "resilient public cyber key terrain", while still getting the edge of the sword you want (allowing these technologies to provoke unrest in countries you don't like) - you pass laws that ruthlessly enforce the use of Tor et al on your own territory, run a lot of psychological operations against the use of those tools by your citizenry, and then spread the shit out of that same technology through covert channels to everywhere else in the world, for those ballsy enough to be "separatists" in their own countries. The politician will think that assuming a powerful security organization and steep enough penalties domestically, you can probably eke a net benefit out of the technology outside of your nation-state with little downsides within you own.

This leads to a scary way of blunting the edge of the sword that a politician thinks could hurt them domestically, and I'm afraid that perhaps in some ways we're going down that path (RIPA 2000 is a good example of that, any type of forced-key-disclosure type of thing, or any type of key escrow and tying laws to requiring key escrow.) In the end it doesn't really work, but it does shed a lot more blood in the process.

rms' statement was

> The Clang and LLVM developers reach different conclusions from ours because they do not share our values and goals. They object to the measures we have taken to defend freedom because they see the inconvenience of them and do not recognize (or don't care about) the need for them. I would guess they describe their work as "open source" and do not talk about freedom.

If you're objecting to that, well, where do they talk about freedom? I'm saying rms appears to be correct because I can't find anything they have to say about the issue. I searched more than the homepage.

You just described the way I launched my first comms network constellation[0] - basically loaded a whole bunch of satellites on a single rocket and deployed them on slightly different orbits, so that they'll spread themselves out as the time goes.

Only mid-launch I figured out I could just put three of them on Kerbisynchronous Equatorial Orbit at 120° phase difference :/.

Yes, KSP is absolutely amazing for learning this stuff :).
