This is a pretty clever use of the blockchain. However, instead of destroying the bitcoins you have (wasting coins is bad, no matter how small) you can simply send bitcoins to yourself and store data in the `coinbase` field. The resulting transaction will appear in the blockchain permanently, and can always be referred back to.

There already exists a service to prove the existence of a document before a certain date (much like the one in the blog post): http://www.proofofexistence.com/ Their implementation details are lacking but it should still be clear enough to get an overview. (Edit: I seem to have missed this link in the blogpost)

Besides hosting checksums, other types of data have been found in the blockchain, such as some Wikileaks content (http://www.thebitcointrader.com/2013/04/25mb-of-wikileaks-ca...) and even links to child porn (http://www.btcpedia.com/ped0-links-in-bitcoin-blockchain/).

A step-by-step introduction to Circus
Part of the disadvantage is that any user of a P2P network can instantly join the network, and then immediately "rat out" any other peer he comes across.

If a network is totally closed off, with a single point of entry, one would first have to take down or infiltrate that single point. For example, if a hypothetical illicit VPN was created, hosted by a large server in Serbia, criminals in the US could tunnel their traffic through chains of proxies, with this VPN server at the end of the chain. US law enforcement would have quite a bit of trouble seeing the internals of this network, at least without significant social engineering and investigation.

If a network is freely joinable and is a "panopticon" (everyone can see everyone else), investigation into the network can be done by anyone anywhere, with ease. What IP addresses are connected, how much data and what kind of data nodes are sending, etc.

In general I agree though. The Bitcoin network and protocol is strong and well-designed, and assuming major governments do not ever outlaw the use of the Bitcoin protocol itself (and they probably won't), it should remain strong for a long time. Bitcoin exchanges are definitely the weakest link.

I've seen this "public timestamping" use case before, which is a very interesting exploitation of BitCoin's mechanic.

It is curious, though, that it bears a micro-cost, even at a thousandth of a penny. I've often heard it said that BitCoin is unique as a currency in that the total quantity is inherently fixed; but in fact, it's destined to ever-so-slowly dwindle over time, whether due to public ledger uses, or the loss/destruction of private keys.

One-off transactions won't register as a blip, it's possible that some future use case might run at such a staggering scale (stock market micro-transactions?) that it leads to a financial tragedy of the commons and deflation runs rampant.

Not being doom-and-gloom, just an interesting thing to think about. Just as we now marvel at the naiveté of thinking that 4 billion IP addresses or 64K of RAM would be more than enough, I wonder if someday we'll look back the same way on the minimum transaction of 0.0000001 BTC.

Anyone have any idea why? It seems to me like seismic shifting underground would be many times worse than above-ground, if only because you have to dig to make room (either before or after such shifts).

I have seen that. I once negotiated a contract going back and forth over 2 months. The total business generated by that contract? 5000 INR. < 100 USD. (Of course, I didn't know that while negotiating the contract.)

I try not to do that now.

I'll second this. A lot of the time it's easier just to hold a foreign currency as-is rather than chugging back and forth.

That said, foreign currency accounts are usually expensive. Westpac quoted me a $60/mth account keeping fee.

Not really an exploitation, even Bitcoin's original whitepaper describes its blockchain as a "peer-to-peer distributed
timestamp server".
Don't worry, if it ever comes to that point I'm sure the central bitcoin authority will be able to introduce new bitcoins to the market.

The articles touches on it, but as a startup Co founder one of the biggest problem in India is - access to Capital. Dharmesh Shah once said - "Indians are terribly practical" and it shows. VCs and even Angel investors stay away from a venture which isn't already turning in profit. Sure, there is a funding once you are making good chunk of money, but for many startups it is too late already.

There's a difference in the quality of life between India and America. If you're starting up in India, you have accepted this difference. Correspondingly, there are differences in the operational reality you face in India as a startup trying to grow. The systems in general work differently than in America. At the same time, if you push through you get to stay on top of your domain a lot longer for that very same reason. Above all, it's a lot cooler working at a startup or starting your own company than working at a big established corporate in India. The jobs available are still not that great. Most of the work at Indian corporates is the second rate work the cutting edge doesn't want to mess with and therefore offloads. This is why there been a boom in India's startup scene in the last five years.

This is bogus. Without revealing the nature of the "fuel" it is impossible to even say that it is an energy source. The electrically heated coil could just be releasing the binding energy in the "fuel". Even the 10X results of this "experiment" support this view as the most likely explanation, Occam's razor and all that. Barring full disclosure of the nature of the fuel and how it is made this should be dismissed as a con.

Did you not post this expecting constructive feedback? Snark aside, chapter 1 of what? You haven't made it clear what this really is. Is this python? Do you want to use a game to teach the language or is this just a game and the language is irrelevant?

I don't think there's a problem with the BSD license, but the GNU license is actually supposed to help with those issues, just not the version used by the Linux kernel (v2).
As textminer says, RFs are really nice in that there are few parameters to tune, and the results typically are not that sensitive to the choice of those parameters (contrasted to, say, SVMs, where you can get killed in performance with a poor choice of tuning parameters).

With the MLaaS platform, all of the model optimization is taken care of under the hood (we also allow users to do their own parameter selection / tuning if desired). Our super fast implementation, WiseRF (10-100x faster than RF in sklearn or R) enables us to efficiently explore the hyperparameter space.

Thanks again for your questions and comments.

As long as we're guessing, here's my idea. An electrically propelled train in a tube. Instead of evacuating the tunnel you have ducts in the walls that vent the high-pressure air from in front of the train to the low-pressure sides/bottom/rear of the train.
This should reduce the energy wasted trying to push a shockwave through the tunnel, and would use the air pressure to keep the train off the walls. This would fit with his "air-hockey" comment, and wouldn't be an evacuated tunnel - which he said it isn't.

edit: And the "loop" part of the name is because the air ducts are loops the same length as the train. They move the air directly from in front where it's high pressure to the rear where it's low pressure.
I think it's even simpler than that; when you own property, don't you typically only own a certain distance down into the ground?
I'm sure the other exchanges will soon follow suit. Since MtGox is responsible most of the bitcoin trades it might as well be Bitcoin.

The Wikipedia article goes into this. They wanted to film widescreen but certain necessary equipment wasn't provided so they filmed in 4:3 but with the idea that you could crop it to 16:9 later. Also most of the SFX were done in 4:3 but could be cropped.

The widescreen conversion thing was executive short sightedness at it's finest!!! We offered to do ALL of Babylon 5 in widescreen mode if Warner Bros would buy us a reference monitor so we could check our output. (only $5000 at the time) Ken Parkes (the "Business affairs" guy) and Netter (penny wise, but pound foolish) said no! So we did everything so it could be CROPPED to be widescreen! Each blamed the other by the way. Doug Netter said, "Ken Parkes said no". Ken Parkes said, "Doug Netter said no". SHEESH!!! So for $75 an episode they could have had AWESOME near Hi-Def.

I would think (probably incorrectly, since I know next to nothing about it) that a ram-based system would inherently have combustion primarily behind whatever tightest-seal exists that's bringing the gasses up to combustion temperature, since doing so would also mean the expansion pushes forward against that seal. Or does simply sealing a bit better cause combustion in front of the seal?

> Hyperloop is a “cross between a Concorde, a railgun and an air hockey table.”

I'm thinking Wing in Ground Effect [1], where small vehicles are launched to supersonic speeds using electromagnetic slings (and perhaps then use their own power to super-cruise to the destination and eventually decelerate). You wouldn't need much infrastructure - the cost would be in the vehicles and launching mechanisms.

Can't you do something like

eval("function() { var open = unlock; " + expression + " }")();

True :) Though IIRC Google's prediction API has been paid from day 1, so it might stick its neck out a bit less than e.g. Reader.
Yes, this got me too. I expected that it would be required to ask the guard for another key, and when that was supported I figured I must've misremembered the command. Then I tried passing in my previous key variable in case it was still stored there. Took a while to try unlocking without specifying a key.
Bottom line: reality is diverging from the models and in some cases diverging from the range covered by the error bars. The radical policy recommendations have been predicated not on some warming or mild warming but on catastrophic warming and been justified by pointing to 'scientific consensus'.

I would still think that Braintree would be a better bet.

They abstract the bank part of the equation as well so you are just dealing with a single entity for any issues that arise. Plus their pricing is a little bit better:

https://www.braintreepayments.com/pricing

That said ANY competition is always nice. The real question though is how they handle chargebacks.
Braintree require you get an NAB merchant account and, if you want to support USD then you have to also get the NAB foreign-currency accounts.
>The one thing that drives me mad about Firefox on the Mac is it's Home/End behavior. Ever since migrating to the Mac, I have remapped the keys to work like on windows and Linux (operating on the current line instead of the current document)

That's because Home and End keys on the Mac, like in the original UNIX, mean the beginning and the end of the document not the beginning and end of a line which is a Windows thing (and since Windows is the overwhelming presence, is commonly misunderstood as the keys themselves meaning that) and since most early Linux desktop environment's aimed to duplicate Windows, is also the default Linux behaviour now.

You will find this behaviour in all Apple provided applications as well.

> I cannot work without a way to move the cursor to the beginning of a line

While that article says it will take 21 minutes to travel from LA to NY, Elon explained that the Hyperloop will make you travel from LA to SF in less than 30 minutes. It's a matter of definition, but I believe the Hyperloop is slower.
The language is irrelevant. It's coffeescript, but the whole thing is 'beatable' with an understanding of logic by following its instructions.

If you've never programmed before at all, some parts would indeed be tricky, including the part you mentioned. Still, if you understand how to solve the logic puzzle, you could do it using a temporary variable as previously demonstrated, rather than the more natural (to programmers) nested calls.
