 41 Bitcoin / Development & Technical Discussion / Re: question about ECDSA on: December 16, 2013, 08:10:53 AM Ah, here we go.  I found this in bitaddress.org's source code.Code:ec.CurveFp.prototype.decodePointHex = function (s) {                var firstByte = parseInt(s.substr(0, 2), 16);                switch (firstByte) { // first byte                        case 0:                                return this.infinity;                        case 2: // compressed                        case 3: // compressed                                var yTilde = firstByte & 1;                                var xHex = s.substr(2, s.length - 2);                                var X1 = new BigInteger(xHex, 16);                                return this.decompressPoint(yTilde, X1);                        case 4: // uncompressed                        case 6: // hybrid                        case 7: // hybrid                                var len = (s.length - 2) / 2;                                var xHex = s.substr(2, len);                                var yHex = s.substr(len + 2, len);                                return new ec.PointFp(this,                                        this.fromBigInteger(new BigInteger(xHex, 16)),                                        this.fromBigInteger(new BigInteger(yHex, 16)));                        default: // unsupported                                return null;                }        };So, I guess that answers that.
 42 Bitcoin / Development & Technical Discussion / question about ECDSA on: December 16, 2013, 07:23:52 AM Recently, I decided that I needed to better understand what goes on in the backend of cryptocurrency.  I've slowly been trying to teach myself to comprehend the various backend protocols.However, I'm a little confused about this.  From my understanding, the "base point" G should be a point, with both an x and a y value.  However, it's given there as a single value, with a compressed and uncompressed form.  The linked pdf doesn't seem to elaborate on this.  What does this number mean, and how do you derive the x and y of the base point from it?Thanks in advance.

Taxes are at the point where they're just ridiculous, and everyone tries to cheat on them as a result. No, I can't blame them, but I don't take any comfort in it either.  It's like saying "Sure, most people in North Korea are starving, but at least the political and military leaders are ok".  Crony capitalism is not a rebellion against western statism, it's an aspect of it that should be opposed just as firmly as any other statist violence.

 45 Bitcoin / Bitcoin Discussion / Re: If confirmation takes 10 minutes, how will I buy coffee at Starbucks? on: December 06, 2013, 10:01:24 PM I think everything that needs to be said has already been said about the OP's question.  I just wanted to comment concerning Starbucks and tax.We shouldn't be celebrating crony capitalism.  Regulations and taxes that are selectively enforced against smaller competitors to the mega-corps are not better than regulations and taxes that apply to everyone.

 47 Bitcoin / Bitcoin Discussion / Re: Help on: December 03, 2013, 03:12:54 PM Take out your hard drive, create a live-cd of a linux distro and boot from that.  The first step isn't really necessary, but it might help peace of mind.
 48 Alternate cryptocurrencies / Altcoin Discussion / Why litecoin? on: December 03, 2013, 02:57:57 PM I never paid too much attention to alternate cryptocurrencies, so apologies if this has already been discussed, but lately it seems people have been getting really excited about litecoin.Of all the various choices, why are people so optimistic about this one?I guess my main question is: what does it do that bitcoin doesn't?  What utility do you expect litecoin to have that bitcoin doesn't exceed?If I was going to pick any alternate coin, it would be one that introduces some innovation, such as namecoin.
 49 Economy / Services / Re: Need a couple of simple programs (xmpp related) on: December 03, 2013, 03:06:00 AM Unfortunately, since I already agreed to gweedo's offer it's too late.  I will keep you in mind as well for future projects.  Just so I know, what language(s) do you work with?
 50 Economy / Services / Re: Need a couple of simple programs (xmpp related) on: December 03, 2013, 03:00:02 AM I forgot one requirement: the "listener" program should automatically accept friend requests, or whatever they're called in xmpp.  Will that be a problem?@moderate- That's a good point.Look, I'm sorry but \$50 is much closer to what I planned to spend on this project.  If I find I'm not satisfied with gweedo's work, I'll keep you in mind.  You have to realize, neither of you submitted any sort of resumes, I have no reason to believe that he's a worse programmer than you.  The price is all I have to go by.
 51 Economy / Services / Re: Need a couple of simple programs (xmpp related) on: December 03, 2013, 02:54:08 AM Alright then, I'll pm you with my email address, you can send the program and your payment address when you're finished.
 52 Economy / Services / Re: Need a couple of simple programs (xmpp related) on: December 03, 2013, 02:49:17 AM That's more like it.  Is it ok if I wait until morning to test it?
 53 Economy / Services / Re: Need a couple of simple programs (xmpp related) on: December 03, 2013, 02:42:13 AM Thanks for your interest.Isn't the server specified as part of the address?I have to admit that 0.2 BTC is a little more than I hoped to pay, but not too much more.  Nevertheless, I'd like to wait for other offers before I say yes.
