501  Other / Off-topic / Re: Using Liberty Reserve? READ THIS NOW! on: February 21, 2011, 12:03:26 AM
What we need is a separate exchange in each country matchmaking people who want to sell/buy bitcoin and not charging commission (or at most charging commission n Bitcoin only which will be hard to trace or tax, at least right now). Correct me if I am wrong - how could such a service be classified as illegal? It's like running an auction portal.

I read someone said bitcoinmarket was in danger? How are they in danger if they only matchmake buyers and sellers (unless there is something I don't know). It is a different story if you accept bank transfers onto your own bank account and then "top-up" people's accounts with this money (like bitcoin-central does) - then it looks like you actually make a profit.

EDIT: OK, such a scenario doesn't keep buyer and seller anonymous, but what difference does this make? Who cares whom they sell BTC to or buy from? I certainly do not and I don't care whether they know what paypal or bank account the money came from. All they know is that I bought or sold bitcoins, they don't know where they came from or where they're going to.

Also, the buyer and the seller can arrange an anonymous cash transaction (since they're in the same country), and with the reputation system, trust shouldn't be a problem.

Would you be interested in broken stuff as well? I have a few broken laptops around that someone could use for parts.

ok, he's gonna do it tuesday morning. he will have an aspiring filmmaker buddy of his shoot it and put it up on youtube.

as for the costume, I think the main point isn't so much that it relates to bitcoin but rather that it gets people's attention. I mean isn't that the ultimate goal? A lot of these suggestions like 1's and 0's will have no meaning whatsoever for the avg wall streeter that will see it. When I spoke with him today, he wanted to wear a hip suit. He is a former male model after all so I'm sure he can pull it off and look good it in. This way, he'll look sharp, but it won't be in the typical wall street navy suit way but rather a funky, hip, colorful way.

Any ugly guy can wear a coin costume. We've got a former model here so let's leverage his skill set. Remember that it's new york and wall street, people here are huge snobs. We see crazy fools on the street all the time so we're desensitized to it. I think it will have a much bigger impact if he looks trendy rather than a wacko. I also think the message will get a lot more respect and people will be more likely to read the flyer if it came from a well dressed, trendy model than a nutcase is a crazy suit.

Sponsors, would this choice of wardrobe be all right with you?

I agree a 100%, was going to suggest that myself. Can't wait to see this.
504  Bitcoin / Mining / Re: Why no GPU support in the standard client ? on: February 20, 2011, 10:01:18 PM
As I said I think an ideal solution would be having an official miner as a separate application, where you could chose between what miner you want to use (miners would be included in the installation package). For example, while configuring the installation the user would have an option of installing different miners:

Please select which elements of the program you want to install:

  • m0mchil's miner
  • Diablo miner
  • jgarzik's miner

etc.

Ideally if the program could also check whether the graphics card is suitable for mining and also advise what prerequisites are needed.

Then, after the installation, you could select which miner you want to use and also, you could specify the switches (like, for m0mchils, you could set -f -v -w etc values in the configuration box). a GUI of the mining process would be extremely nice too.

I know this is a lot of work, just saying.
505  Bitcoin / Mining / Re: Why no GPU support in the standard client ? on: February 20, 2011, 10:48:13 AM
How about separating the mining part from the Bitcoin client altogether and having a separate application for mining (but also hosted on bitcoin.org)? Whoever doesn't need to mine can just download the client itself. The mining application would have a nice GUI and a lot of configuration options. The only thing that the client could have is adding username and password to the bitcoin.conf from the GUI level. The mining application could contain different miner versions (m0mchil, diablo, rpc etc.) and the user could just pick one - then the application would advise them about prerequisites needed for each miner). I know this is very rough, just thinking aloud. But something could come out of it, perhaps.

What I'm offering to someone interested would be the followign thing : you buy BCEUR in bulk and resell it charging a fee.

Why ? Because accepting wires from people eats time, because I'd rather get one or two significant wires than lots of small ones over the same period.

I might be interested. PM me with the amounts and details. As you know I have bank accounts in two European countries.

Didn't you get this working on Windows after?
508  Other / Obsolete (buying) / Re: 50 BTC if you write a complete guide on GPU mining on Ubuntu using ATI on: February 19, 2011, 06:14:06 AM
1. The final instruction assumes you already have 'bitcoind -server' running. I hadn't realized that the RPC was not optional (and had been assuming the RPC stuff was there for people who were parts of a pool) until someone mentioned the '-server' option and I saw there was no such option in the poclbm code.

This is more miner related thing, you should have checked m0mchil's miner thread for general instructions. The tutorial was written specifically for me and I did not ask for explaining that. Its only purpose was to get me going with my ATI cards.

Quote
2. the 'export' library path stuff seems incomplete. I kept getting a libOpenCL.so.1 error with poclbm (which I knew I had installed as part of the tutorial's directions), and eventually slocate told me where it was and I did another export command which went like `export LD_LIBRARY_PATH=/usr/lib/nvidia-current/:/opt/ati-stream-sdk-v2.2-lnx32/lib/x86/:$LD_LIBRARY_PATH`

The path quoted by Raulo works perfectly for me (unless obviously you are using the 32-bit version).

Quote
3. hardwiring the paths is a little annoying because I had to rewrite all the filepaths (I'm on i386). Maybe this could be turned into a genuine pastable script

Good idea.

Quote
4. the tutorial advised me to the 2.1 SDK, but this seemed to lead to odd problems which went away with 2.2. On the other hand, I hadn't rebooted so I'm not entirely sure what was going on there.

Apparently the 2.1 SDK is the most efficient one (for mining purposes) on Linux.

511  Economy / Marketplace / Re: Drugstore.com & Beauty.com with 5% discount for bitcoin (Limited time offer) on: February 18, 2011, 02:58:00 PM
#2. I don't like this offer for some other reason of which I am not sure , I just can't put my finger on it.

Maybe too much hassle involved? (fake accounts, emails, screenshots, confirmations etc)

I wouldn't bother either, but thanks for the initiative.
512  Bitcoin / Bitcoin Discussion / Re: The threat of centralization through pools? on: February 18, 2011, 11:16:39 AM

I don't mind if there is a bit of centralisation, as long as it is not coerced.

There can be many pools, with different rules.  Plus, nothing prevents you from investing in a lot of CGU and do your own mining.


Yes. But what I am trying to say is that it would be much easier for some organization hostile to Bitcoin to turn off (or attack) a few pool servers than to disconnect thousands of single users.
513  Bitcoin / Bitcoin Discussion / The threat of centralization through pools? on: February 18, 2011, 10:50:11 AM
The recent rapid increase of generation difficulty got me thinking: soon for most of us pools will be the only option to generate any coins. The problem with that is that we are leaning towards centralization - if someone wanted to attack the network they would nearly had to attack the pools (e.g. slush's pool with 60GHash/s is a huge chunk of the overall power of the Bitcoin network).

Any thoughts on that?
514  Economy / Marketplace / Re: I buy vintage PC games for Bitcoins on: February 18, 2011, 10:23:26 AM
I have an uncountable number of 1990's computer games! However, most of them do not have their original packaging, if even the CD case. A lot of them are also old grade school education games, like jumpstart type stuff. But, I do have others too.

Hi,

Unless you have some really unique stuff, I would rather go for the ones in retail boxes etc. Any chance you could create a list (only those in boxes)? Thanks.

Any PCI-E x16 risers/extenders? They would be really popular in here ^^

Sorry, no. :/
516  Bitcoin / Bitcoin Discussion / Re: inheriting bitcoins on: February 17, 2011, 01:40:36 PM
This is another reason for getting your close friends and family (or lover) to look at Bitcoin. If they knew how to use it, no need for any instructions. Just like leaving someone your house in your will - they don't need to learn how to use it. Smiley

EDIT: This is a very interesting topic, I was actually thinking about what will happen to my Bitcoins if I die in a car accident or something. My first thought was: I must show my wife how to use it properly.
517  Other / CPU/GPU Bitcoin mining hardware / Re: Hello, I have an old GPU on: February 17, 2011, 11:31:35 AM
This is a good place to look for stats on GPUs: http://pastebin.com/AvymGnMJ. A 4650 should expect about 33Mhash/s. In slush's pool, 1Mhash/s is about 1 share per hour, and each share is roughly .002BTC. So, a conservative estimate of 30Mhash/s would put you at mining 1.44BTC/day. Hopefully that will cover the cost of the electricity you will use mining that!

What bout a NVidia Geforce 7300? It's not listed on that page.

Also, what kind of stats would a Pentium D 2.8ghz get?

Basically, nVidia cards need to support CUDA, ATI cards need to support OpenCL in order to use them for mining. Just check the links below and you will know:

518  Bitcoin / Development & Technical Discussion / Re: Maximum number of bitcoins on: February 17, 2011, 11:27:07 AM
Is there a solution to this?

A solution to what?  Don't lose your bitcoins.

Problem is, If I lose bitcoins, the market loses bitcoins. The solution I'm looking for is to the inevitable deflation. If Bitcoins are to be a stable currency, it must be, you know... stable.

You can make as many copies of your wallet.dat as you wish. You cannot make any copy of your real coins that you can lose due to having a hole in your packet. This limits the probability of losing bitcoins greatly, unless someone is stupid enough not to do backups.
519  Bitcoin / Bitcoin Technical Support / Re: HD 6850 + HD 4850, second card can't use OpenCL? on: February 17, 2011, 10:52:14 AM
I think it has something to do with the fact that you have two cards in one machine. I couldn't get Windows to work with two 5850 and had to (with pleasure) switch to Ubuntu. Works like a charm (thanks to Raulo).

EDIT: Sorry, you didn't say that you're on Windows, but I am assuming so since you use ATI Stream SDK 2.3?
520  Bitcoin / Bitcoin Technical Support / Re: Which operating system will bitcoin work on best? on: February 17, 2011, 10:49:30 AM
Looks to me like you are just missing some C/C++ libraries. Probably you can easily download them, but I am not a C programmer so not sure.
