Currently this film is english only. It needs to be translated in various languages to reach wide audience. Streisand effect could help too.

Most people who claim it was someone else are idiots - it's kinda like Holocaust denial 2.0 and should be outlawed.
Outlawing a conviction was common in the dark mid age and is common in the Islamic State todays. Such law would create a new reason to argue against the official 911 theory.
Someone who's really right doesn't need to aid the law because he's just right. As it would be rubbish to create a new law who forbids to deny the gravity.

I'm missing a generic "in a religious buildung" option.
I think the chanting in a Hare Krishna temple is even worse than a christian sunday bible class because they pray - for me it's lying too - very fast and for hours nonstop.

I don't think penalties are a good thing. The next politician could intruduce the same thing with his scam coin instead.

It's better to reward buyers with discounts instead.

46  Bitcoin / Bitcoin Technical Support / Re: What happens is BTC is sent to incomplete address? on: April 26, 2015, 07:04:38 PM
The validation rules are applied when taking the user's base58 input. This is done by the user's client only. After passing the checks, the client constructs the raw transaction which is finally seen by other clients, as known as the network.

In spite the final raw transaction is checked by the network, the raw output script which defines who can claim the funds was derived from the originating base58 string doesn't have a check sum anymore and thus the transaction wouldn't get rejected as long as the constructed transaction follows the rules of the protocol.

This means: As long as you use a well reviewed client sort of the known like Core, Electrum, Armory, you shouldn't fear of sending to an incomplete address.

If you use someone's else unreviewed client or you're even about to roll up your own bitcoin client, a flaw in the validation mechamism could trigger unpredictable behaviour which includes crashing and refusing to accept a valid bitcoin address - in the best case. In the worst case a heavily flawed client could technically craft a valid transaction from faulty treatment of invalid user input which renders the funds inaccessible.

Usually fiat money up to 500 $ equivalent because I pay almost everything in cash.

If Q1, Q2, G, and n are known, is it still difficult to determine k1?
  • Yes, knowing Q1, Q2, G, n is not sufficient to calculate k1 easyly because there is no known fast method doing a point division.
  • Knowing Q1, Q2, G, k1 is not sufficient to calculate n easyly
  • Knowing Q1, n, G is sufficient to calculate Q2 easyly (Q2 = Q1 + G*n)

   Q2 = n * k1 * G?
If one of n, k1, G is not known, you can't recover it's value easyly because it would involve point division. If Q2 is unknown, you can calculate it easyly just by multiplying.
50  Bitcoin / Development & Technical Discussion / Re: An easy way to remember a bitcoin address on: March 07, 2015, 03:04:25 PM
My (practical) approaches:

#1
Advantage: Works on every internet capable computer without any prior arrangements if you trust traditional block explorers like blockchain.info, otherwise additional trusted software setup is required. Very easy to memorize.
Disadvantage: You're likely going to fund criminals some satoshis.

Creating:
1. Just generate a bunch of random bitcoin addresses (a1, a2, ... an)
2. Send 0.00005460 to each a1 ... an
3. Choose a brain wallet "b" with your full name (not an issue, bitcoiner who reuse don't care about privacy anyways) or something very easy to memorize. If address "b" has already transactions, use another phrase and repeat 3
4. Send a1 ... an to b (brain wallet), don't care whether your satoshi are being flushed by the bots because you just do it once

Receiving bitcoins:
1. Enter your brain wallet phrase and navigate to "b". The inputs of the first transaction seen on blockchain are holding your secure generated a1 ... an bitcoin addresses
2. Choose one from a1 ... an
3. Receive

Sending bitcoins:
1. Open your client which contains the securely generated private keys of a1 ... an
2. Send


#2

Using namecoin


Feel free to improve it if you think it's useful.

Hopefully, things like bitcoin will be a driving force for TPM chips, small crypto chips embedded in your computer, that stop attacks like these.
I don't want my computer to be locked up like iOS one day just to have the advantage to shift the responsibility over my computer to some "goverment trusted" foreigners. If I don't want responsibility which is the downside of freedom, I'm better off with fiat in use with traditional banking.

Why, Blizzard, Why?   Sad
"WoW Gold" can be frozen, credited, deducted, transfered and destroyed on Blizzard's demands. On contrast, Bitcoin doesn't have this advantage. That's why creating an own currency is better for Blizzard.

I'm using VPN anonymizers for years now and VPN is a service which usually has to be paid.
To expose as less as possible, I used to pay the VPN anonymously with a voucher which I purchased either on the gas station or in the kiosk using cash.

One day I wanted to extend the VPN membership because it was to expire again. I went to a kiosk and asked for the voucher, same procedure like all the years ago. This time the assistant was picking up paper and pen, started to ask me for my full name and address which should be verified of course. I refused and left, moving to the next shop but everyone refused me to hand out a voucher without my full details.

Later on, I tried several mobile phone shops and computer stores instead, close to nobody knew what I was talking about when mentioning the voucher. After walking a marathon lasting two days, I had luck in an small ancient dithy&messy looking second hand mobile phone shop. He finally handed out the voucher without checking my identity, he even didn't asked for, finally!

In the evening after extending my membership I logged in to my standard chat and had a talk about my great journey and the disturbing development everything being registered and logged. A privacy enthusiast replied, these vouchers are "dead" right now due to new regulation, I should start to use bitcoin and buy the bitcoins with cash either on a bitcoin conference or by arranging a face to face meeting.

Thats how I started with bitcoins. The next extension of my VPN membership was paid just with bitcoin.

Blockchain.info seems to be working fine, what's the issue?
The site runs but it's bitcoin client is disconnected from the remaining world and the site doesn't showing up any new blocks.

This isn't the first time that it happens.

TL;DR : Nothing severe - don't panic

Looks like that you forget to hex encode it.

Your result from your first try (#x####AA@###"##a##z###a####) looks like the raw byte representation of BA7816BF8F01CFEA414140DE5DAE2223B00361A396177A9CB410FF61F20015AD but with #-replaced unprintable.

58  Other / Off-topic / Re: Judge my wallpaper on: February 25, 2015, 07:39:51 PM
My opinion:

Wallpaper 1 http://imgur.com/Q7BWMoU is too color-saturated to stare at for a longer time and thus it is not suited for a wallpaper. The symbol left looks strange to me and it looks like a quick photoshop project.

Wallpaper 2 https://i.imgur.com/thsDval.jpg (origin found at http://rekano.deviantart.com/art/Dream-of-a-Photomanipulator-144970294 with reverse google image search) looks much better. Pity that it's only 1200x900. Nice to look at but still suitable for a wallpaper if the monitor doesn't exceed HD screen resolution.

Wallpaper 3 http://alpha.wallhaven.cc/wallpaper/169338 is a nice one too, well suited for a dark desktop environment.

Creating wallpapers is more than just creating anything artfully to look at. The work should have good quality (at least FullHD) and take care of the human ergonomics.
59  Bitcoin / Bitcoin Discussion / Re: What would you do if you wanted to stop Bitcoin? on: February 21, 2015, 03:39:23 PM
If I had much power and wanted to stop bitcoin I would start three big campaigns worldwide:

1. Making links to child porn as illegal as the child porn content itsself, no matter if the link is still working or not. Avarge Joe would agree. (imho the blockchain already contains these links - if not, a hacked pedophile's computer can be used to add these links to the blockchain).

This should heavyly decrease the number of full nodes at least.

2. Support trusted computing as a safety feature. Avarge Joe would eat this. This locks up every OS including Linux/Ubuntu and Windows like iOS. Because the blockchain is illegal, no official Bitcoin app will be ever released.

After this, with no official exchanger and requiring to jailbreak your own PC first to install all the anonymity and bitcoin stuff, the usage should be close to zero now.

3. Altering the principle how the internet works and advertise this as a protection against cyber crime, pedophiles and terrorist. Avarge Joe would eat this. Altering the principle means: slowly replacing IP with a closed source one which supports goverment issued certificates and disallows the usage of arbitrary P2P. Every running service needs to be approved by the goverments first. If replacing IP is too slow, the other approach is to block incoming connection requests by the internet service providers which restricts arbitrary P2P too beside the political pressure to introduce expensive licenses to operate a server (which means accepting incoming connections).

Now with no free P2P, no unregulated VPS due to licenses, with the need to jailbreak your computer prior to install Bitcoin and no anonymization service because they don't get a license, the blockchain has no place to exists anymore and finally dies.
