As u probably know, a black hole is a star with gravity that prevents light from escaping. Today I noticed a similar effect during downloading Bitcoin blockchain.  Grin
It's a star that has collapsed on itself.
1702  Bitcoin / Hardware wallets / Re: Why isn't there a single purpose bitcoin hardware wallet ??? on: September 14, 2013, 09:52:21 PM
Why do we still have to use multiple purpose hardware like smartphones and pc for wallets ? Ever since I have known bitcoin I have been waiting for a secure hardware wallet for sending and receiving bitcoins so to introduce bitcoin to my family and people around me that aren't tech savy enough to keep their bitcoins safe. And don't tell me that trezor is a wallet it is just way secure your wallet.

We could put up a bounty for the development of of an open source hardware wallet.




by single purpose hardware wallet I mean something like the bitcoincard but no need for the mesh network nor for it to be this thin and small =v        

If you really want one, you could've just made one yourself...
1703  Bitcoin / Bitcoin Discussion / Re: Howcome so little traction in online porn world? on: September 12, 2013, 04:16:05 PM
Bitcoin may yet, erm.., penetrate this market  Grin Though I think more the problem in that industry is finding what people will actually pay for than the method of collection, not to say taking digital currency wouldn't be a lot easier and cheaper regardless.

Because people would rather download it from somewhere, than pay for it.


Generally, yes, but some (that don't know what BitTorrent is anyway) will shell out some cash for high quality productions, or at least high quality video. Thanks to the Internet destroying DVD sales porn studios have to come up with something that will sell as a premium service or product.

I don't think there is anyone that doesn't know what BitTorrent is, if he uses a PC and has internet anyway.

All of her response could logically follow from the information you gave her, except for the wall penetration part... That seems an odd choice of words. Of course to us that has meaning with regard to the hashing algorithm that secures the network, or the overall block chain and proof of work scheme which has 51% attack vulnerability.

wall penetration is wording used in investments.. so just him saying investments the reply of wall penetration does sound as a natural flow of conversation. nothing at all to do with the algorithm
Nah, trust me, being from the same country as OP these so called clairvoyants are nothing but scammers. I mean she gave him the answer he was looking for, so...
1706  Bitcoin / Bitcoin Discussion / Re: A clairvoyant on Bitcoin :) on: September 11, 2013, 07:17:37 PM
I went to a clairvoyant a week ago.

I decided to ask her about Bitcoin ... so I said (translated from Bulgarian):

- What can you tell me about Bitcoin ?
- Bi*@# what Huh I don't know ...
- Please, just tell me whatever you get from 'above' ? ...
- Flawless ... Just that word !
...
Then I asked her:
- Should I invest in it ?
- It can be penetrated ! - She said - The wall against it can be penetrated. It can succeed !

That was what that woman told me. I am sure she haven't heard of Bitcoin before.

Нека да позная, циганка?

1707  Bitcoin / Development & Technical Discussion / Re: RNG using Block informations on: September 07, 2013, 12:32:19 PM
Could you describe a specific use case?  i'm having a hard time imaging what the hmac_sha512 of a blockhash could be used for.

You could for instance take the first decimal via pregmatch and use it as a 0-9 RNG. My test script that I ran hundred of times (1 billion iterations each) verifies that it's evenly distributed 0-9 and no number is in favor.

Quote
Since I think the nonce is fairly random
Are you referring to the nonce in the block header?  If so, it's not necessarily random (it's possible to mine with nonce set to a constant, for example), and it's certainly quite biased.

Okay, how about taking the exact blocksize as the second secret then? That should be unguessable before the block gets found/generated?

Then how would you know it beforehand to use it yourself?

i found it amazing that someone like him would still be using Windows.

Not at all.  It is not worth the hassle and bother to protect much of the work that any normal person does.  A person who has some understanding of the various threats will be perfectly comfortable using systems such as Windows OS, Google geo-tracking, etc, most of the time.  If not all of the time.

An interesting thing about the surveillance state apparatus is that it is actually counter-productive in the very few instance when it might be useful to attack a worthy (and thus dangerous) opponent.  This because someone who knows what they are doing can probably fool the algorithms and produce data which will discriminate them out of a suspect pool.  But the surveillance state apparatus is not probably so much about catching 'bad guys' as it is about mass intimidation of the general population.  Snowden assisted in this whether it was his goal or not...and I'm glad he did no matter what his motivations.  So far there have been no big surprises to those of us who have been paying attention over the years and take a conservative approach to security threats.

A relatively modest group effort to fight against state sponsored privacy attacks would be easy and effective I suspect.  It would involve an understanding of the systems through some combination of whistle-blowers and reverse engineering, and fucking with the system by poisoning it with bogus data.  We ('freedom fighters' if you will) do need a ground-up open-source set of solutions which spans the spectrum of hardware, firmware, and software though.  I hope that that evolves out of our recent more broadly appreciated understanding of the shape of things.


Considering how many Windows kernel hackers(good ones) there are, surely they would've noticed any backdoors by now!? Or running Windows in a VM and listening for strange outgoing connections?

Firstly, beware of spyware!!!  I use a mac and have no problem, pc's beware.

The movie is Kickass 2.  At ~26:33 the recorder warns a fellow movie go'er to shut up, LOL!  I just thought it was funny.  Watch any movie anytime.
Lol, never thought anyone would notice that. It was like "Listen mate I'm trying to record this so if your friend can't eat those a little more quietly I am gonna rip your balls off.

Code:
bool check_collision_rect(Rect *A, Rect *B)
{
    // The sides of the rectangles
    int leftA, leftB;
    int rightA, rightB;
    int topA, topB;
    int bottomA, bottomB;

    // Calculate the sides of rect A
    leftA   = A->x;
    rightA  = A->x + A->w;
    topA    = A->y;
    bottomA = A->y + A->h;

    // Calculate the sides of rect B
    leftB   = B->x;
    rightB  = B->x + B->w;
    topB    = B->y;
    bottomB = B->y + B->h;

    // If any of the sides from A are outside of B
    if(bottomA <= topB) {
        return false;
    }

    if(topA >= bottomB) {
        return false;
    }

    if(rightA <= leftB) {
        return false;
    }

    if(leftA >= rightB) {
        return false;
    }

    // If none of the sides from A are outside B
    return true;
}

and

Code:
double distance(int x1, int y1, int x2, int y2)
{
    // Return the distance between the two points
    return sqrt(pow(x2 - x1, 2) + pow( y2 - y1, 2));
}

bool collision_circle(Circle A, Circle B)
{
    // If the distance between the centers of the circles is
    // less than the sum of their radii
    if(distance(A.x, A.y, B.x, B.y) < (A.r + B.r)) {
        //The circles have collided
        return true;
    }
    
    // If not
    return false;
}

Fixed your code. Issues included no spaces between comments and double slashes, failure to put opening curly bracket for if/else/for/while constructs on same line as opening statement, failure to align assignment operator for variables belonging to a group, and excess spacing around parenthesis.
Those are just semantics, I write clean code, if you see how the MyBB team code it's just gorgeous.

Plus

if(eval)
{
    // code
}

is much better than

if(eval) {
    // code
}

Collision is simple, assuming that your characters are rectangles here is a sample of my old code

Code:
bool check_collision_rect(Rect *A, Rect *B)
{
    //The sides of the rectangles
    int leftA, leftB;
    int rightA, rightB;
    int topA, topB;
    int bottomA, bottomB;


    //Calculate the sides of rect A
    leftA = A->x;
    rightA = A->x + A->w;
    topA = A->y;
    bottomA = A->y + A->h;

    //Calculate the sides of rect B
    leftB = B->x;
    rightB = B->x + B->w;
    topB = B->y;
    bottomB = B->y + B->h;

    //If any of the sides from A are outside of B
    if(bottomA <= topB)
    {
        return false;
    }

    if(topA >= bottomB)
    {
        return false;
    }

    if(rightA <= leftB)
    {
        return false;
    }

    if(leftA >= rightB)
    {
        return false;
    }

    //If none of the sides from A are outside B
    return true;
}

and

Code:
double distance(int x1, int y1, int x2, int y2)
{
    //Return the distance between the two points
    return sqrt( pow( x2 - x1, 2 ) + pow( y2 - y1, 2 ) );
}

bool collision_circle(Circle A, Circle B)
{
    //If the distance between the centers of the circles is less than the sum of their radii
    if(distance(A.x, A.y, B.x, B.y) < (A.r + B.r))
    {
        //The circles have collided
        return true;
    }
    
    //If not
    return false;
}

It's true actually Sad the internet isn't being as original as it used to be, maybe everyones working on news stuff or something, i need to hurry up and finish learning the coding I need so I can make some fun games to play and not be bored anymore lololool Cheesy
Already ahead of you Cheesy

Looks like space invaders + mario
Yeah, I was inspired by mario. At first I was going to make so you could walk up,down,left,right but then decided to make it like Super Mario from 84 for SNES.
