Ah, here we go. I found this in bitaddress.org's source 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.

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.

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.
Right, and the answer is to end the regulations and taxes. The problem with uneven oppression is not that certain people aren't oppressed enough. Agreed. Looking at it from their point of view, when the government slaps them with a 60% tax rate can you really blame them for trying to worm their way out of it? 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.

My guess is they searched for Nelson Mandela on google, and Freeman's picture came up because he played Mandela in Invictus.

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.

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.

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.

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?

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.

Alright then, I'll pm you with my email address, you can send the program and your payment address when you're finished.
|
|
|
That's more like it. Is it ok if I wait until morning to test it?
|
|
|
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.

I've tried to find existing tools to do this, but I didn't get anywhere. If you find programs that fit these two requirements, and walk me through their installation, configuration, and use, I'll pay you a bounty of $35 in btc. Otherwise, I'd like to comission someone to write them. Program one: I need to be able to send an xmpp message from the command line, providing sending address, password, receiving address, and message in one go. Something like: Program two: This program takes three parameters: xmpp address, password, and command. It listens on the address it is given, and whenever it receives a message, it calls "command" with the sender's address and message as parameters. Something like Language doesn't matter too much, but I recommend ruby due to the fact that its "blather" xmpp library seems most up to date. The fewer dependencies the program has, the better. I will test the completed programs on a selection of xmpp servers, using pidgin as the "control group". If you write these programs, I expect to have access to the source code. You may share it freely, and/or make it open source. I'm using this solution simply because I've given up hope at being able to directly use the language of my main project, which is common lisp. If you can create a working library (cl-xmpp returns an error for me), I'd be willing to pay even more. If you're interested, let me know what you intend to do and how much you want for it.

One question to consider is which countries will allow you to stay indefinitely as a non-citizen without a job. Unless you're willing to frequently return to the states, that might limit your options somewhat.

Sorry, that was a typo. They do share a common etymology.

Why would that matter? The yuan is over-valued and will fall against the dollar once it floats. That's one reason Bitcoin is doing so well in China - its perhaps the only freely convertible currency.
What makes you say that? Seems to me the dollar is over-valued vs the yen. How else do you explain our ability to maintain such a massive trade deficit with China for so long?

Ok, I'll throw out some random ideas.
Local residential and store front roads would probably be maintained by some organization equivalent to a Home Owner's Association. Businesses already share parking lots (I assume), so it's just a simple extension of that concept.
Major avenues could be toll roads. In order to prevent long lines at the entrances, I wonder if it would be possible to tag each car with an RFID tag. Drivers would be able to purchase "plans" based either on time ("one month of access") or on a specific number of entries. As each car goes through the entrance, the tag is checked. If someone enters without a valid tag, a photo of the vehicle is taken and broadcast to nearby security vehicles so they can be sued at a later time.
In crowded downtown areas, I see mass transit supplanting cars. If it can't be made independently profitable, it can be subsidized by an association of local businesses, as I described for residential roads.
When it comes to inter-city travel, I see railroads making a comeback. You could have a system that allows people to park their own vehicles right on flat rail cars and ride the train that way.
Emergency services would have to make greater use of helicopter transport.

Brick-and-mortar exchanges, supermarkets, hardware stores, gas stations...
We're getting there, but there's a way to go yet.

That should be fine, but why bother with a passphrase at all? Why not just let bitaddress randomly generate your addressed using their "single wallet" or "bulk wallet" option?
