Instead of "gpg_identity=", what about some URI style format such as "GPG:"? |

how far are we from a total implementation?
Very far. |

Those metallic surfaces can radiate energy out. But, that's all you can do in space. Conduction and convection are out. And just as a surface can radiate heat, it can also absorb radiation, from the Sun for example. Oops, I'm afraid you're right. That was silly of me but I forgot that. I guess cooling electronic devices is indeed tricky in space. |

I think you could use the code I wrote in my thread about a full shell script implementation of bitcoin: bigEndianHex2littleEndianHex() {
local s=''
while read -n 2 char
do s=$char$s
done
echo $s
}
bitcoinHash() {
bigEndianHex2littleEndianHex |
xxd -p -r |
openssl dgst -sha256 -binary |
openssl dgst -sha256 -binary |
xxd -p -c 80 |
bigEndianHex2littleEndianHex
}
And then with the following data from the current block: ver=1 prev_block=0000000000000000000000000000000000000000000000000000000000000000 mrkl_root=4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b bits=486604799 (this is the genesis "data") You can create a next block by searching a nonce like this: nonce=0
while
time=$(date +%s)
printf "%08x%08x%08x%064s%064s%08x" $nonce $bits $time $mrkl_root $prev_block $ver |
bitcoinHash |
grep "some test I don't know exactly"
do nonce=$(bc <<< "nonce + 1")
done
of course a lot is missing, especially the network part. |

I'm not an engineer or anything, but I'm pretty sure it easy to cool an electronic device in space. Sure, you don't have any environnmental fluid to carry heat away, but you have plenty of space that you can fill with zero-weight (considering zero gravity) metallic pans. Maybe just behing solar panels. Those metallic surfaces can radiate energy out.

Sorry, I haven't read this whole thread but I've seen that some people managed to hash at around 280kH/s. I know the N900 has some graphic capable hardware: any chance this device could be used to hash?

True.
clearsigned message -> SHA256 -> eBay my world ?
Of course it doesn't help if the eBay account was hacked.
Well, if your account has been hacked, then you need to publish a message saying: "I used to be xxxx on eBay, but my account was hacked in 20xx." |
|
|
|
Nope i don't get it as well.
So wtf ?
I'm guessing there is an hidden transaction behind, possibly for money laundring. |
|
|
|
Well, it's not easy, since you must avoid quotes and anything that look like HTML, but I've managed to put "I am grondilu on eBay" in my contact information section on http://myworld.ebay.com/grondilu. Carriage returns are skipped, too. PS. I've filtered GnuPG's output through xxd -p. I think it's enough. |
|
|
|
Not an entire public key, but the GnuPG fingerprint would be fine I guess. You can also qrencode it and show the image in your profile. PS. This actually gave me the idea and I've just done exactly this for my avator on this forum  PS#2: you can also stenography your public key inside the photos of the items you're selling, although I suspect eBay is altering the pictures. PS#3. Nah I changed my mind and removed the qrcode 'caus it's ugly. |

Well, bitcoin is not in this list, is it?

You might have a look at davout's website code, if you like ruby.
I have also been thinking about that for a few weeks now. I'm working on yet-another implementation in bash.
The problem with this kind of stuff is, as you pointed out, it's easy to make a simple implementation but much more complex if you want to make it optimal.
I can't believe there is not more public documentation about these kinds of algorithms.

I don't know much about certificates, so correct me if I'm wrong, but:
Basically with a self-signed certificate you just have to accept it the first time you connect to the website, and then, if later I'm being warned that the certificate is not the same anymore, then I can suspect there has been something smelly, and ask around about it.
To me that sounds pretty much as good as relying on a third party "certificate authority".

I think bitcoin is the seed and if it ever fails another will quickly assume it's place. The genie is out of the bottle...
True. Bitcoin has shown that a currency can be decentralised. This is big news. |

I think the photo of Anna and the Yap stone is just fine. It has some surprise effect and has the merit of getting out of tech context.

Also, always check out biddingpond, for I often sell gold coins there.
I'll sell an other one soon.

1) Bitcoin's mainstream acceptance is not that important. An idea would be quite useless if it has to convince every single person in the world in order to be efficient. I don't want to rely on other people's smartness and awareness, because it would be hopeless.

I think you are overestimate them a bit.
1) Bitcoin's mainstream acceptance is not that important. An idea would be quite useless if it has to convince every single person in the world in order to be efficient. I don't want to rely on other people's smartness and awareness, because it would be hopeless. So I say I don't care if government is using propanganda to discredite bitcoins, just as it chose to promote Keynes's idea about gold being the "barbarous relic".
2) If government is capable of taxing bitcoin, then bitcoin is not that great anyway, and we'll have to think about something else.
3) This is a serious threat but there's notrhing we can do apart from trying to improve the software.
4) They can try, just as they tried with gold, by holding huge quantities of it. But to do so they'll have to buy some in the first place, which would increase the price of bitcoin and thus draw attentionto the public. I'm not sure it would be a good strategy for them.

I very much doubt Szabo is Satoshi, but I've enjoyed reading his blog article "Some speculations on the frontier below our feet". Quite fascinating, sometimes people dream about exploring out of space, and yet there are some quite interesting discoveries to make right here on Earth. |
