These privacy bugs are well known to the people who put them to use.

jafaku··on What's your chance of getting a U.S. work visa? Find out with BorderScore
I'm not planning on going to America because a) I'm more interested in seeing other places (sorry) and b) It's impossible anyway. But let me tell you something: When I leave, I won't be depriving "my own society" (whatever that means) of anything, because that's how much value I can produce here, with all the corruption and bureaucratic obstacles.
jafaku··on Secretive Bitcoin Startup 21 Reveals Record Funds, Hints at Mass Consumer Play
It's not idiotic, that's why there is a Bitcoin fund, and soon there will be a Bitcoin ETF.

If being an expert in computer security isn't "specialized knowledge", I don't know what it is.

> Paypal hates it, as does India's Reserve Bank.

I can't believe this doesn't immediately make you think that maybe, just maybe there is something good about Bitcoin. Are you 0K with the central bank stealing wealth from you and your family through the debasing of your currency? Are you 0K with working your ass off so that bankers and other powerful people can live a life of wealth and pleasure? How can you take advise from such people?

"Bitcoin is bad, don't use it! It's a drug currency... very shady... also, terrorism!"

That is basically what every central bank said to the people in their country.

That's not really a possibility, it's just your desire to see Bitcoin go down. I don't know why there are so many people so salty about Bitcoin.
jafaku··on Why is perl losing its touch?
> what it doesn't have is anonymous functions

If it's not anonymous it's not a closure though.

jafaku··on Why is perl losing its touch?
Which popular language nowadays doesn't have closures? Even the so hated (by HN) PHP has had that for many years already.
jafaku··on Why the world's biggest military keeps losing wars
That happens everywhere to some degree. In corrupt countries it's very common that politicians announce the building of big schools and hospitals, but the projects are never finished. The construction companies bribe the politicians to get the contracts, and then it doesn't even matter whether they ever complete the job, no one will control that.
jafaku··on Blockstore: A Key-Value Store on Bitcoin
No, because the miner who gets the fee isn't the only one who will have to work extra. All full nodes will have to relay and store that transaction. And there is no known way to pay full node operators in a way that can't be abused.
jafaku··on Why the world's biggest military keeps losing wars
Where is that from?
jafaku··on Blockstore: A Key-Value Store on Bitcoin
No single entity controls it, but that doesn't mean you can do whatever you want. If someone is abusing the blockchain by bloating it with useless garbage, there will be consensus for fixing that. So don't build a business or technology around abusing Bitcoin's blockchain, because you will be left out.
jafaku··on Why Do Cats Love Boxes?
But cats also love to sit on squares or circles (no walls). Try creating a square with tape on the floor.

Then make the scheme 4 of 5, or 3 of 5. Besides, the company could keep a backup of the keys in physical locations, and secure them with traditional physical security.

That "paid actor" has a Strongman career. See his personal records:

https://en.wikipedia.org/wiki/Hafth%C3%B3r_J%C3%BAl%C3%ADus_...

If you think your "leg work" can save you from someone who can lift 400+ Kg, you live in fantasy land. Unless you mean you will run like hell.

There is a reason why contact sports like Box or MMA have weight categories. Size matters! And swords aren't such good weapons that they remove the strength factor. If we were talking about guns, or even bows, then sure, dexterity beats everything else. But in close combat you don't want to fight someone who can literally crush your body with his bare hands.

Edit: A picture with Arnold, for comparison:

http://www.dv.is/media/cache/0c/10/0c10973a39a53647327481c60...

And Arnold didn't focus on strength when he trained, but this man did. Imagine that.

> Is it that the interviewed HEMA "girl" enjoys the fact that size is less important in her sport than in some other sports?

With a very serious face she said exactly this: "It's a serious martial art". Then the narrator says she's already a champion (with just 3 years of training? while studying/working as an engineer? lol) that fights opponents twice her size. And then she goes on with her fantasy: "It's hard for me to fight small people because I'm SO used to fighting with people taller than me or larger than me" (yeah right, that totally makes sense, lol). And then (some context huh?) she says that size shouldn't matter. I have seen this sort of delusion in many activities, including but not limited to religion and "martial arts". And let me tell you, it's all fun and games until someone crashes against reality.

> Is it that her sport is not as "real" as your favorite HBO program?

I specifically said both are fantasy. But it's hilarious that you out of all the people try to mock me for this. By the way, I'm pretty sure the actor who plays the Mountain got more training than you. I would bet my life-savings to him in a fight where he used only armour (no sword) versus you or your "champion" with armour and a real sword. It will probably end like this:

http://youtu.be/pRY4Mpmfk1o?t=3m19s

That's not the Mountain by the way. Check him out: http://media.joe.ie/wp-content/uploads/2014/02/gameofthrones... . But don't worry. What does it matter that his arm is the size of your torso? You are very fast and skilled. It's not like he wouldn't cut you in half with a single swing, right? Because size doesn't matter.

> Oh, now I see, you're an iaido fan.

No, you don't see ;), because I'm not a Iaido fan. In fact I've never even tried it.

> After all the other stuff you've said, that's just cute.

Is it. I think you are cute.

If it was seen just as a sport or a game, kind of like cosplay, I wouldn't mind. But the girl in the video truly believes she's a warrior and that can't end well.

I never said they were good fighters, just that they practice with real swords, while in Kendo they don't. But of course they fight even less than the guys from Kendo, because nobody wants to get a scratch nowadays. So people only have two options: "fight" with fake swords, or learn to use real swords but without fighting. I'd take the second option, but I think both are pretty much useless.
jafaku··on Inside the world of longsword fighting
I don't want to be a dick, but have you actually had a real sword fight? Have you pierced someone's armor and make him bleed? Of course you haven't.

The Mountain is a fictitious character from the popular TV series Game of Thrones. He uses a huge sword that you wouldn't be able to stop the same way you stop your fake swords brandished by girls. And I only dared to use him as an example because all of this is basically just that: a game, a fantasy.

If I had to pick a guardian, I would choose a newbie sword man from the middle ages over your instructor (who has never had a real fight) any day.

If you think Kendo is real, see what the guys from Iaido have to say about them: When they pick a real sword, they simply can't handle the weight, and the ones that can don't know how to actually cut stuff, because all they have learned is to win points in a game similar to tag.

jafaku··on Inside the world of longsword fighting
Why the downvotes? This is swords and armours, not guns. Strength matters a lot. Since apparently you already live in fantasy land, why don't you try fighting "The Mountain"? Then tell me if size doesn't matter.

> Multisig offers you no benefits if you're not the one in control.

That's a little extreme. I would trust a lot more in five employees than in one. If done right, each one of them could even not know who the other employees are.

> Are you sure you want to trust your fortune to three or five employees?

I wouldn't trust anyone with my precious coins :p. I'm just saying the same way we (supposedly) decentralize control on nuclear bombs, we can decentralize control on bitcoins. I feel safer knowing that no single soldier can launch a nuclear bomb, even if I don't have any control over that.

jafaku··on Coinbase Exchange
For example: You can only have so much security if you don't have security experts. Same with every other area. I don't remember the details now, but their first iterations were pretty lame.
jafaku··on Coinbase Exchange
I can't believe they aren't using multi-signature internally. This is crazy.
jafaku··on Coinbase Exchange
The goal of multi-signature is to decentralize the ownership (or control) of the coins. In the case of Coinbase's offline storage, they could very well be using multi-signature (and they probably are) so that no single employee can run with the coins. Instead, every time they need to refill their hot wallet, the three or five or whatever employees needed to sign the the transaction have to agree and provide their signature.

Edit: Actually, apparently they aren't using multi-signature internally: https://news.ycombinator.com/item?id=8948337

jafaku··on Coinbase Is Opening the First Regulated Bitcoin Exchange in the U.S
"As much as I wish Bitcoin would go away"

But why? I don't understand why Bitcoin generates negative feelings in so many people instead of just indifference.

jafaku··on Coinbase Exchange
Some Bitcoin exchanges have two options for orders: "Immediate or cancel" and "Good until cancelled".
jafaku··on Coinbase Exchange
> This means 98% of customers don't have multisig control over their coins, since multisig-protected coins can't be put into offline storage.

What makes you think you can't use multi-sig and offline storage at the same time? That's just false. You don't need an internet connection to sign a multi-sig transaction.

But I agree on everything else: 98% of funds aren't insured, and to me Coinbase has always been just another Rails startup (not necessarily a bad thing, but they made tons of mistakes typical of having web developer talent only).

jafaku··on Coinbase Exchange
But they will charge a 1% fee on the exchange, which in this case would be 2.78. Another difference (I think) is that they often cancel your order as brokers (many people have complained of buying, and then when the price goes up Coinbase rejects their buy order), but not as exchange.
jafaku··on Coinbase Exchange
It's the first licensed (as money-transmitter) exchange. The first non-licensed was Gox I guess. And Kraken is European I think.
