I doubt there are any algorithm or any human being that can detect if somebody is doing this kind of fraud, unless he is a serial fraudster.

I never said (or did I ?) that it will stop all scams.
But it is MUCH better than nothing.

I only wanted to create a solution which will enable re-opening of the trade websites.
2183  Economy / Marketplace / Re: BitSwap on: October 25, 2010, 10:16:21 PM
I have a few observations.

1. It looks terrible.
2. YAK ! Dark green ! This is disgusting.
3. It does not look trustworthy. You really need to create a more professional image if You want people to trust You with their money.
4. You are a newbie on this forum, with 17 posts, with no reputation. How are people supposed to trust You anyway ?
5. Your domain name is VERY bad & unprofessional, If You're wanting to do some serious buisness with it.
6. EDIT: No SSL ? Not even a non-authority-signed certificate ? What is this ? It definately looks like a scam site, i can tell You.
7. Are you serious about this at all ?
8. GOTO 1
2184  Bitcoin / Development & Technical Discussion / Re: Use XDG folder instead of .bitcoin on: October 25, 2010, 04:16:15 PM
Agreed, but with one adjustement:

there should be a ~/.bitcoin symlink to ~/.local/share/.bitcoin

Not everybody is used to the "new way" and will look for the bitcoin folder in wrong place.
2185  Economy / Economics / Re: Price Deflation Discourage Investment? on: October 25, 2010, 10:52:24 AM
So the answer is yes; price deflation discourages investment. But we must understand that it is more accurate to say that the inflation tax encourages investment, because the investment that would go on with a zero-inflation currency is the baseline.

I would say that currency inflation encourages both wise investments and stupid investments, while currency deflation encourages only smart investments.

With deflating currency it is not beneficial to take big risks while one can earn more with just keeping money in his socks.

The question is: is that good or bad ? I personally think it is good, because :

1. If people stop doing stupid investments, there will be less of poor people.
2. People will be able to get richer just by keeping money in a safe. So anybody can invest easily, poor & stupid people too.
3. Less stupid investments = less financial crisises.

So the conclusion is that difference between rich and poor will decrease. Everyone will get richer. Deflationary economy is IMHO much more stable than inflationary economy.
2186  Economy / Trading Discussion / Suggestion for dwdollar & other BTC traders: How to fix the SCAM problem on: October 25, 2010, 10:09:04 AM
I see that bitcoinmarket registrations are still closed, so I'm proposing a solution which should fix the paypal, moneybookers & other "soft" currencies scam problem, so the site can be opened immediately:

1. Allow trading in "hard", non-drawbackable currencies (such as Pecunix, LibertyReserve, Wester Union etc.) to everybody.

2. Allow trading in "soft" currencies only for users which are trusted. Trusted means:
a) Are registered for 3 months or longer, or are registered & trusted now
b) Have traded at least X BTC minimum and have perfect trade history without any scams or other problems
c) Have verified their credentials through some mechanism - credit card, mail verify code delivery or personal digital signature.
The solution can be composed of all a) b) and c) or their combinations.

3. Force all Paypal & Moneybookers transfers to wait at least 5 days before they can be finalized. This should solve the stolen credit cards reversal problem.

4. Allow paying with paysafecard and such.

Idea sounds interesting, but I'd like to hear satoshi opinion on this very much.
Satoshi, where R you ?
2188  Other / Off-topic / Re: True Goal of Satoshi on: October 25, 2010, 07:50:47 AM
thats what I think, too...

it's strange that you don't find Satoshi on any popular social media site. if he'd be a known hacker or computer freak / specialist, you'd be able to find him nowadays in the internet

That is actually quite normal for a hacker/specialist.

I also try to keep away from any social-oriented sites, because they do great harm to one's privacy.
Most of normal people don't realize what these sites are doing to them, so they don't care. People who know how stuff works much often avoid such risks.

I am doing that myself, and many of my colleagues which are IT specialists do the same. What is put into internet just once, stays there forever.
2189  Bitcoin / Development & Technical Discussion / Re: Suggestion: Allow short messages to be sent together with bitcoins ? on: October 25, 2010, 07:42:30 AM
Why should we reinvent the wheel when theres an existing way to do things ? When you send a bitcoin to a merchant you also send them a tweet or direct message on twitter!. Twitter allows you to add metadata to tweets http://dev.twitter.com/pages/annotations_overview .

1. We definately should not use any third-party tools for messaging.
Messaging should be done only using some decentralized protocols.

I mean what will happen if some company buys twitter and concludes that it should not exist and then shuts it down ?
Using external services as the core of bitcoin functionality is just not safe.

2. I agree with Satoshi on this - a separate protocol should be used. Perhaps another P2P protocol, or some messaging protocol like Jabber. Let's stick to the Keep It Simple Stupid (tm) rule.

It doesn't work with r173:

Forgot to tell You - don't use the *-9999-* ebuilds. They never worked for me either.
I'm deleting them from server. Also deleting all other irrelevant files & adjusting the Manifest.

The only working ebuilds in my release are "0.3.*c" ones.
2192  Bitcoin / Development & Technical Discussion / Working CUDA Gentoo ebuilds for 0.3.13 and 0.3.14 on: October 24, 2010, 04:20:54 PM
Hello,

I'm starting this thread to maintain my Gentoo bitcoin ebuilds for CUDA version of bitcoin.
I will start a github repo later, so for now, ebuilds, patches and full sources are avaiable here:

http://tinyurl.com/2ujagcw

These are simply patches from puddinpop, adjusted for the newest version and with makefiles & dependencies added.
I also hope for some help from the author (puddinpop), because i don't think i can maintain this on my own for long, as I am not a C/C++ programmer, I am just good with patching & diffing.

I tested it on my 64Bit Gentoo, and they compile fine, but some paths are adjusted for 64bit Gentoo, so the ebuilds may not work without small adjustments of makefile (in net-p2p/bitcoin/files/Makefile.gentoo.cuda). So if it does not compile for You on 32bit, then try adjusting these paths in the makefile:
Code:
CUDALIBPATHS= \
 -L$(CUDAROOT)/lib64 \
 -L$(CUDAROOT)/sdk/shared/lib \
 -L$(CUDAROOT)/sdk/shared/lib/linux \
 -L$(CUDAROOT)/sdk/C/lib \
 -L$(CUDAROOT)/sdk/C/common/lib/linux/ \
 -L$(CUDAROOT)/open64/lib

Any donations to make my effort worthwhile are welcome.

Also, I'd like to point at that bitcoin should adhere to the KISS philosophy.

+50 to that.

KISS philosophy is what makes Linux so great.
2194  Economy / Trading Discussion / Re: A Heroin Store on: October 23, 2010, 09:54:37 PM
My guess is that if we don't want to be advertised as "drug dealers" and "money launderers" by all the governments, we should stay away from such a buisness.
Or perhaps try to avoid doing it for at least few years, until bitcoin becomes mainstream.

Of course while saying this, I'm perfectly aware of that people will do otherwise, so i don't really know if there was point in saying it at all...
2195  Economy / Marketplace / Re: Selling on ebay... on: October 23, 2010, 07:47:33 PM
It is a pity that ebay does not allow bitcoins.

But this is not surprising because they own paypal, and they will do everything possible to defend it. (look at the last week's earning release from ebay. one key driver for profit growth was paypal...)


Actually, You're creating unnecessary theories about it. They don't accept bitcoin simply because it is a currency. And they probably do not allow exchanging any currencies on their site, except for "collecting" reasons.
2196  Bitcoin / Development & Technical Discussion / Re: Suggestion: Allow short messages to be sent together with bitcoins ? on: October 23, 2010, 07:41:02 PM
ECDSA can't encrypt messages, only sign signatures.

It would be unwise to have permanently recorded plaintext messages for everyone to see.  It would be an accident waiting to happen.

If there's going to be a message system, it should be a separate system parallel to the bitcoin network.  Messages should not be recorded in the block chain.  The messages could be signed with the bitcoin address keypairs to prove who they're from.

I think I didn't exactly understand how the system works. So if the messages would be sent together with bitcoin, they will also be permamently stored in the block chain for ages.

It seems you're right, satoshi.
2197  Bitcoin / Development & Technical Discussion / Re: Suggestion: Allow short messages to be sent together with bitcoins ? on: October 23, 2010, 06:33:56 PM
I very much don't like this idea of a message.  Since it is not necessary to the protocol, I'm not sure if it would be easy to find a place where it really fits.  I'm not a programmer though.  I'd be curious to have Satoshi's thought on this.

Yeah, I'm curious of that too.
2198  Bitcoin / Development & Technical Discussion / Re: Suggestion: Allow short messages to be sent together with bitcoins ? on: October 23, 2010, 05:59:43 PM
I found something interesting.

http://stackoverflow.com/questions/1138345/best-compression-algorithm-for-short-text-strings

There is a small OS project on github, which does good compression of short text strings.
http://github.com/antirez/smaz

Quote
'This is a small string' compressed by 50%
'foobar' compressed by 34%
'the end' compressed by 58%
'not-a-g00d-Exampl333' enlarged by 15%
'Smaz is a simple compression library' compressed by 39%
'Nothing is more difficult, and therefore more precious, than to be able to decide' compressed by 49%
'this is an example of what works very well with smaz' compressed by 49%
'1000 numbers 2000 will 10 20 30 compress very little' compressed by 10%

In general, lowercase English will work very well. It will suck with a lot
of numbers inside the strings. Other languages are compressed pretty well too,
the following is Italian, not very similar to English but still compressible
by smaz:

'Nel mezzo del cammin di nostra vita, mi ritrovai in una selva oscura' compressed by 33%
'Mi illumino di immenso' compressed by 37%
'L'autore di questa libreria vive in Sicilia' compressed by 28%

It can compress URLS pretty well:

'http://google.com' compressed by 59%
'http://programming.reddit.com' compressed by 52%
'http://github.com/antirez/smaz/tree/master' compressed by 46%

So we could further get the 384 bytes down to <200 or <175 bytes.
2199  Bitcoin / Development & Technical Discussion / Re: Suggestion: Allow short messages to be sent together with bitcoins ? on: October 23, 2010, 05:13:01 PM
What about the increase of the block size, then ?
Even if 512o per transaction is small, it might represent a significative amount since all has to be stored in the block chain.

I will tell You what have i just done.
I clicked "quote", copied the message and pasted it in a text file.

Then, i have truncated the file to 512 bytes, and EDIT: GZIPPED  it. It now takes 329 bytes.
Next, i have bzipped it. Now it takes 288 bytes.

Of course, there is no need for such a long message. Let's try 384 bytes. I used lorem ipsum generator from here: http://lipsum.com/
Results:
Code:
-rw-r--r--  1 user user  384 2010-10-23 19:09 ipsum.txt (uncompressed)
-rw-r--r--  1 user user  274 2010-10-23 19:08 ipsum.txt.bz2 (bzip2)
-rw-r--r--  1 user user  268 2010-10-23 19:10 ipsum.txt.gz (gzip)

I think that maximum ~260-280 bytes per transaction is not bad.
2200  Bitcoin / Development & Technical Discussion / Re: Suggestion: Allow short messages to be sent together with bitcoins ? on: October 23, 2010, 03:45:45 PM
a paiement label is not necessary.

Sure it is "not necessary" but still would be useful for people.

Perhaps some people would like to keep one BTC address for some reasons.
Also bigger financial institutions won't really like the idea of different account number for each transation.
