From http://www.ugtv.org/glenneichler.php:

MTV's greatest weakness is also their greatest strength . The fact that nobody's paying very close attention, and the primary objective is to do things on the cheap, means that people are allowed to be creative, where at other networks, where there's more at stake, (i.e. money), people aren't allowed to be as creative...

http://bitcoin.org/ official site currently lists developers as:

    * Satoshi Nakamoto
    * Gavin Andresen - (PGP)
    * Pieter Wuille
    * Nils Schneider - nils.schneider@gmail.com (PGP)
    * Jeff Garzik - jgarzik@exmulti.com (PGP)

Latest http://archive.org/ snapshot shows developers as:

    * Satoshi Nakamoto

    * Amir Taaki - (PGP)
    * Pieter Wuille
    * Nils Schneider - nils.schneider@gmail.com
    * Jeff Garzik - jgarzik@exmulti.com (PGP)

which removes Amir Taaki's name from the list.

(I may have missed some, sorriez, please let me know if I have)

I see that Amir Taaki has 0 commits to the repository (but a few pull requests) and therefore makes sense that he is removed from the developer list in that regard.

How come only a select few of the developers that DO have commits are listed on the main page?  What is the procedure necessary to deserve accreditation or recognition?  Perhaps it may be useful to have a page on the site that credits everyone that has contributed so that each person may deserve their fair share of recognition for their contributions?

Discuss!  Also, see this.

Hey genjix here, I'm posting as mizerydearia since I'm not logged in ... blaa blaa

Here;s a fast way to calculate difficulty. It uses a modified taylor series for the logarithm (you can see tutorials on flipcode and wikipedia) and relies on logs to transform the difficulty calculation:

Code:

#include <iostream>
#include <cmath>

inline float fast_log(float val)
{
   int * const exp_ptr = reinterpret_cast <int *>(&val);
   int x = *exp_ptr;
   const int log_2 = ((x >> 23) & 255) - 128;
   x &= ~(255 << 23);
   x += 127 << 23;
   *exp_ptr = x;

   val = ((-1.0f/3) * val + 2) * val - 2.0f/3;
   return ((val + log_2) * 0.69314718f);
} 

float difficulty(unsigned int bits)
{
    static double max_body = fast_log(0x00ffff), scaland = fast_log(256);
    return exp(max_body - fast_log(bits & 0x00ffffff) + scaland * (0x1d - ((bits & 0xff000000) >> 24)));
}

int main()
{
    std::cout << difficulty(0x1b0404cb) << std::endl;
    return 0;
}

Unfortunately I don't have much use for it in libbitcoin. Maybe some miner will find it useful.

To see the math to go from the normal difficulty calculations (which require large big ints bigger than the space in any normal integer) to the calculation above, here's some python:

Code:

import decimal, math
l = math.log
e = math.e

print 0x00ffff * 2**(8*(0x1d - 3)) / float(0x0404cb * 2**(8*(0x1b - 3)))
print l(0x00ffff * 2**(8*(0x1d - 3)) / float(0x0404cb * 2**(8*(0x1b - 3))))
print l(0x00ffff * 2**(8*(0x1d - 3))) - l(0x0404cb * 2**(8*(0x1b - 3)))
print l(0x00ffff) + l(2**(8*(0x1d - 3))) - l(0x0404cb) - l(2**(8*(0x1b - 3)))
print l(0x00ffff) + (8*(0x1d - 3))*l(2) - l(0x0404cb) - (8*(0x1b - 3))*l(2)
print l(0x00ffff / float(0x0404cb)) + (8*(0x1d - 3))*l(2) - (8*(0x1b - 3))*l(2)
print l(0x00ffff / float(0x0404cb)) + (0x1d - 0x1b)*l(2**8)

Since bitcoin is peer-to-peer, does that fact alone 100% guarantee that it is incorruptible?
Is it possible in any way or fashion to corrupt bitcoin?

> wardearia it is "possible" but not easy
> define corrupt

Kardos, Having or showing a willingness to act dishonestly in return for money or personal gain.
from google results

> sigh, i mean in your context

I have no idea how to define it in my context

> well theres plenty of scammers turning up
> bitcoin itself is not an intelligent entity that can become corrupted by greed

that last line alone seems to imply such a sentence is erroneous

-

What seems like a more accurate way to rephrase the statement:

Bitcoin is the world's first decentralized means of payment and as such incorruptible.

Something like this as a mobile bitcoin atm would be awesome!

I propose a forum board to be created for all threads regarding Bitcoin forks.

Moving such threads, including the wildly popular https://bitcointalk.org/index.php?topic=36218.0 to offtopic seems rather strange, if not kind of odd.

You cannot delete your own topics in this board.

Yet again

http://forum.bitcoin.org/index.php?topic=33185.0;topicseen

http://bitcoincharts.com/

Relatedly, all data feeds for ALL exchange sites in #bitcoin-market have stopped too, because nanotube's bot is reliant on bitcoincharts.com for data.

I, for one, highly suggest alternative noncorrupted bitcoin market data sites to exist.

Is there a bitcoin library release available or any developments for a bitcoin library?  Is there a list/comparison of them anywhere? Maybe something like https://forum.bitcoin.org/wiki/doku.php?id=list_of_patches or https://forum.bitcoin.org/wiki/doku.php?id=repositories ?

If you're anti-government, etc, then how teh fuck can you be so effortful towards "properness"  WTF?  FUCK PROPERNESS! DIIIIEEEEEEEEEE!!!

This is to introduce the opening of https://intersango.us a new USD exchange site.

This is being run by the https://bitcoinconsultancy.com/ the same group running https://britcoin.co.uk

I lost 1 bitcoin.

Hello,

You haven't lost the BTC. It takes up to 24 hours for a BTC transaction to reach its destination. It should be in your account by tomorrow evening.

It ended up that my ASK/SELL order took up to 24 hours to be manually activated/allowed.

What?  Discrimination!

<wardearia> Hiya.  How come http://britcoin.co.uk/ and http://intersango.com/ are not on listed at http://bitcoinwatch.com/?
<censored> intersango does not have trades yet and britcoins API is broken
<wardearia> How so?
<censored> it has a strange orderbook entry (something around 9 billion GBP for 0.0016.. BTC)
<wardearia> That means the API is broken?
<censored> well not broken, but my backend refuses to parse such absurd data
<censored> people have been complaining about the invalid data so I figured it would be best to hide it until it is resolved
<wardearia> So then hide the data?  Don't delist the exchange?
<censored> that's what I did. I clicked "hide" in the backend.
<wardearia> The particular data that is related to what your backend cannot handle, not all of the data
<censored> the backend doesn't support that
<wardearia> Did you write the backend?
<censored> yes
<censored> the problem is actually pretty simple: the underlying database model is limited to 10 digits and 8 decimals. changing that would require migrating about 8 GB of data
<censored> also, other exchanges with similar absurd orders were happy when I reported them so they could fix their exchange
<censored> when did I give you permission to cross paste this on the forum anyway?
<wardearia> You didn't.  Shall I censor your name?
<wardearia> I changed it
<censored> first, you should not make anything I say in private "official" (like posting it on the forum)
<censored> so could you remove that forum post?
<wardearia> I made it "unofficial"
<wardearia> If there were a zimbabwean dollar exchange, would your site be unable to handle the data?
<wardearia> sites*
<censored> why?
<wardearia> I'm curious
<censored> should work fine
<censored> if there are problems I can still migrate the database schema
<censored> the problem with the order is more like this: if I extended the schema to allow more digits one user might discover that a decimal can have more than hundred digits and place a order for 0.00000001 BTC @ 10000000000000000000000000000000000000000000000000000000000000000 GBP. same problem again
<wardearia> Is it possible to ignore such data and continue parsing remaining data?
<censored> nope
<censored> well, technically yes, but it would break the incremental orderbook feature

Today's deal for Google Android 2.2 HDMI TV Set-Top Box has exact same description as http://www.dealextreme.com/p/google-android-2-2-hdmi-tv-set-top-box-72086

See http://forum.bitcoin.org/index.php?topic=25624.msg321614#msg321614

Hi - I run BTCDeals.com -

One of the suppliers I use is indeed DealExtreme. I do add a slight markup on the items (but if you do the math on most items, it's very little) for my time, overhead and risk - but mostly I run BTCDeals.com as my way to invest in to the bitcoin market. I cashout the value needed to cover my costs, while all profits I leave in bitcoins in a separate wallet that I keep as an investment. I'm pretty open about how I run the site and am more than happy to answer any questions (except the full list of suppliers I use)

It may seem obvious to just order directly from DX, but the service I intend to be offering is a way to purchase items with BTC instead of your personal currency and utilizing your bank or paypal accounts.

In the end it's up to you, the consumer - just trying to help fill a void in the bitcoin market, and obviously help myself be part of the bitcoin economy.
