What about XMPP for network communications ?
And a NoSQL database for storing blocks ?


sqlite is probably the best client database to use. There are many object frameworks to use with it if you don't like sql.

What we're going to do? Call the police?

 Cheesy You can't be serious...


The result would probably that if the police ever did investigate, they would report you to the IRS for tax fraud or something like that.

A currency exchange is convienient to begin, but eventually goods and services must be offered for bitcoins to be useful.

A bank does need something more than most other sites. I would be happy to pay a fee to have two-factor authentication on my MtGox account.

My bank snail mails lists of 300 one-use keys you need when logging in. A quicker but perhaps more expensive option is to send the keys in SMS.

An application for your mobile phone that generates a lot of one time passwords, and then encrypts using the servers public key and sends the list to the server to be used. You can then use the passwords when you need, as long as you don't lose your phone.

But I think authentication using public/private keys is better, as long as you don't lose your key or let it get compromised.

MtGox could/should also implement Facebook/Google logins.

Good idea. OpenID, in other words.

Google even offers two-factor authentication to some of its users (password plus mobile phone confirmation).

Or he should not use passwords at all an use gpgauth.

http://www.curetheitch.com/projects/gpgauth/

Right now there is no working plugin for browser but there should be soon, from what I have read. It is also not just a technology, program but a process, protocol for authentication.

Password based authentication has many weaknesses, a move to keypair based authentication is the better thing to do. Then things like dictionary attacks, stealing passwords after breaking in, and rainbow attacks, and storing passwords will not be a problem.

Any news from mtgox and getting his bitcoins back?

Just a thought like. I've got this on ONE core, and I went out and left it on by mistake. Come back and the sofa on the other side of the room is scorched.

c'mon - this level of CPU caning is taking the piss

Skype nicks your bandwidth (I think) but it doesn't make the fans on your laptop scream.

Very interesting thread.  I was thinking bitcoin and geocaching would be useful for drug crops futures contracts. The contract would say which country it will be in, and once the date for delivery of the crop has arrived the contract owner would receive the gps location (probably berried in the desert or in a forest). This would be useful for wholesale of the product with the last mile covered by the dealer friend network. It would also make it easier for planning production of the drugs.

Mining bitcoins will not always be profitable, and may not be worthwhile after a 6 month time period if difficulty increases too much. At that point we will have a number of machines which we can use for other purposes and with which we can make further income. And once we are finished we can sell the equipment, not at the price we paid but for something.

Outsourcing everything would make sense if we were an existing company trying to cut costs in something that is a cost center and generates no revenue. But this will be the core business of our club for some time. Doing it ourselves alows us to develope expertise which we will need. If we use your service Vladimir along with it being more expensive we will be left with nothing but a few bitcoins, and no expertise or equipment to use for something else, and our club must then disband.

If we do it ourselves then we will be in a position to do more things once we have finished mining, these would be more opportunities to make more bitcoin and at the same time have more sefvices or even products available in the bitcoin economy.
2872  Economy / Economics / Re: RFC: Is there anything like a good government intervention? on: January 28, 2011, 02:01:47 PM
With relation to healthcare, in America healthcare is available at need but at high cost, this high cost is caused by excessive government regulation.

In countries where healthcare is "provided" by the government there is a shortage of it, or if the cost is heavily subsidised there will be a shortage of it. The example being all government funded health systems in Europe, some better or worse than each other.

Any time when you fix a price below the market price the result is a shortage, that is what money is for, in economic terms, to allow the distribution of finite resourses to people who have infinite wants and needs.

The display of shortage of healthcare in The EU is in waiting times, waiting times for what may be basic proceedures or tests, very often these are the cause of many patients becoming dead while they are waiting for tests. It is also displayed in the quality of healthcare which is far below the expensive, but private healthcare in the US.

In China healthcare is regulated by the government,not too heavily. There are some private hospitals but nearly all are government owned. And the patients must pay the full cost of healthcare at treatment(cash up front). The cost for Chinese people is very high but that is because their pay is low, the cost for western people is very low.

For example, I had a small tumor, the size of a ping pomg ball removed from my buttox for about $120, all costs included. For an American this might not be muct but it was a lot for me.

The short version, all government intervention causes costs to go up and quaity to go down. Beaurocrats must be paid and they do nothing to help the system they work for, but make it worse.Driving up costs and driving down quality.

In second the government also outlaws competition, also keeping prices up and quality down, and this is what most regulatin does, outlaw competition. It is why everywhere in the western world you can never get a Taxi and why they are so expensive.

Stefen Molyneux expressed a lack of interest in accepting Bitcoin donations in favor of PayPal donations.  If you consider it, it's quite conflicting considering his agenda.

It could also be that he doesn't understand bitcoin.

In 2009 Osaka zoo, which is publicly funded, bought six koalas from Australia which cost a combined $1.4 million per year to feed. Osaka has the highest population of homeless people in Japan, and the decision to spend tax dollars on the zoo, instead of on the homeless, angered some of the homeless and others in Osaka.

What we do NOT want is one or more of these services being ran by one, single person, as that person would, if their service was executed successfully, become unbelievably rich in Bitcoins

Why don't YOU be that person, then when you become rich you can give away your coins to "people who don't have the time or skill to set up their own Bitcoin-earning service/product".

I think we need a mechanism where we can use resources of those who have so much they don't need all of them and then we can use them to assist those who have not had the good fortune of having their own mining machine.

Homeless people don't starve or freeze to death unless they refuse help. I see no evidence that voluntary charity would achieve this.

Homeless people are often those who are made helpless by the state.

Homeless people are cash-poor but time-rich. There are types of homes that require a lot of time but very little money to build. Two examples are straw bale housing, and yurts.

Suppose a homeless person finds a farmer who will let them build such a dwelling on an unused piece of his land, perhaps in return for some help with milking the cows. Do you think the state will allow this?

The land has no "planning permission", and the building is too non-standard to be approved. So the homeless person is denied an honest way to lift themselves up, back into mainstream society.

In my country there are a few people who have managed to convince the bureaucracy to allow them to live in straw-bale houses or yurts. But the people who succeed in this interaction with the state are not the ones who are struggling and really need the permission.

As for voluntary charity, it's empirically shown that charity flourishes when the state is smaller, and that charity languishes when the state moves in on its turf. But even with a dominant state, private charity flourishes when there is an exchange.

What I mean by this is, for example, that the Salvation Army is always willing to help you, but in exchange you may need to listen to the word of God. Fair enough. If I was a destitute atheist I would respectfully do that, in order to lift myself out of poverty. Then, I would gratefully make a large donation back to the organization that had helped me, before severing all ties with it.

I have read about shacks being built on the sides of motorways in the UK and Ireland (there are usually a lot of trees where they do), and in Japan there are blue bag/box apartment buildings. Where homeless people have built their own two or three floor apartment building out of boxes and bags for waterproofing on public land (parks etc.)

Some of the points mentioned in the mining association page are not an issue, such as securities law, it is up to us whether we want to follow any laws set by outside governments(which government? where is our club located?, in cypherspace, it is like being in a different world), they won't be able to enforce anything.

We don't want to incorporate outside the bitcoin economy, at least not yet, this adds extra; many extra costs and delays. If this is the route taken then most of us would be better off just building our own machine.

The easiest, fastest way to raise btc for this project is to sell dividend paying shares. At the very worst this can be done semi-manually (digitally signing shares, collecting bitcoin addresses to pay to etc.), but this is something I am building into my trading platform.

The dividend paying share will also have voting features(using signatures), that is it will be easy to vote on motions and verify those votes.

We sell the shares, the users buy the shares, we build the miner, start making btc, and start paying out.

I don't know who made that page(there is no username, noagendamarket can you change the settings so that only registered users can edit pages on the wiki) but I think that is a poor argument, things are moving much faster in the bitcoin economy than in the mainstream, we can't do things the way they  are normally done (we don't have any way to enforce our rules with courts or police and we're so distributed that there is no point in even trying to do things the old world way), take some useful conventions (shares, double entry accounting, auditing, some company roles etc.) and forget the rest.

On a related topic, the motherboard and psu choice in the hardware section are bad. There are a few motherboards that have four PCIE 2.1 x16 slots (MSI890-GD70), this means that it can have 4 graphics cards(instead of just two). And because of this the PSU needs to be more powerful, over 1250W

We can expect to pay around $3000 for a 4 x ati5970 mining machine.

The wiki page, "expressions of interest" is not needed. Essentially once we have our plan and structure in place, we can announce the selling of shares. Those of us here who are involved can prebook at a fixed price for a specific number of shares prior to launch. The rest we can make available for bidding (I will be building that into my platform also, if it is not ready at that time we can use biddingpond). If our "club" or whatever we want to call is going to be profitable then everyone who has bitcoins will buy shares.

I also think there should be another position in the club, if we are going to be basing so much on technology and cryptography we need a Technology Officer.

Roles include ensuring methods, uses, and protocols of cryptographic tools (or software in general) used or developed are sound and secure. As well as conducting any "cyber auditing" that needs to be done.

I'm working on some financial cash flow projections and I need some help. I'm not sure how to figure out how much power the mining rig will use each day. I probably could, but I know someone else already knows how, so if they could post the calculation here I can build it into the spreadsheet and save a little time.

Thanks.

With 4 graphics cards the rig can be expected to use around 1200W per hour, that by 24 is your answer.

I'll have a look at the bylaws a little later, Im busy now.

This is only a little related to the above thread. Can we make building bitcoin a little easier? After finding the binary doesn't work on my server (amd64 ubuntu 8.10) I went to build and found out about all the libraries it needs (that are not available as apt-get for this distribution).

Probably not too important.
