Ok.. i have read the FM... problem solved thanks! CXX checkpoints.o In file included from checkpoints.cpp:7:0: main.h:22:29: fatal error: PoWCore/src/PoW.h: No such file or directory #include "PoWCore/src/PoW.h" ^ compilation terminated.  You can read more, and then immediately shout. What is wrong? How did you fix this? I'm having the same issue. Within the Gapcoin main directory do: git submodule init
git submodule update

For the non math experts, what is the advantage of solving these? This advances mathematics, and therefore technology, theories, and a general understanding of reality? How does this compare to the technology in XPM Primecoin?
The are many relations between prime numbers and our nature: http://www.bbc.co.uk/news/magazine-14305667In fact prime numbers are fascinating in many ways: God may not play dice with the universe, but something strange is going on with the prime numbers. Prime numbers are important to every day cryptography (see RSA). Researches about prime gaps could not only lead to new breakthroughs in the bounded gap, it may also help proving the Twin Prime Conjecture and maybe even the millennium problem, the Riemann hypothesis. Who knows? While Gapcoin searches for rare prime gaps, Primecoin on the other hand searches for long prime chains: http://en.wikipedia.org/wiki/Cunningham_chainhttp://en.wikipedia.org/wiki/Primecoin |

maximum merit for day 33.27006847~ 19 place in Top-20 merits. Yes, we've been lucky the last days  I already submitted the last gap to the record keeper, but I didn't get a response till now. |

[2014-12-26 05:37:04] Error receiving message form server: read_until: The file handle supplied is not valid I'm using this arguments gapminer.exe -o mine3.gap.nonce-pool.com -p 3385 -u user.lol_1 -x pass -t 4 --stratum Please help  Hi, unfortunately stratum isn't really working, but you should be fine using getwork. Nonce-Pool supports vardiff and long polling with getwork: gapminer.exe -o mine3.gap.nonce-pool.com -p 4200 -u user.lol_1 -x pass -t 4

New top merit! 33.48912446
Overtakes Donald Knuth's record of 33.4536
Merry Christmas everyone! Looks like we just got a present from Gapcoin |

It's nice to see some movement here This coin has a nice concept, I also like the scientific background. I think a rating system and search function would be beyond the scope of Datacoin and is better left implemented by sites that would link to DTC files or by a derivative wallet. However, the core wallet should definitely implement user friendly uploads and downloads via txid or other identifiers.
I guess voting and comments could be submitted to the blockchain, they just need to refer to the original torrent via an id (the hash of the magnet link for example). I think the HTTP servers should parse the data from the blockchain and store it in a database, this would also allow searching, just like collecting the votes for one torrent without scanning the whole blockchain. Agree with this. Sending JSON to blockchain is not hard, but what if the user spams the blockchain with a 5 star rating to his torrent? A solution could be vote confirmations, where each vote has to be confirmed by another voter, but then again, how can you prevent people from voting for their rating? But the starting point in my solution is good in itself, so maybe work on something based on that? How about a voting like in Memorycoin. The weight of a vote is determined by the Datacoin volume of the voters address. No matter how often someone votes, his vote would only count as high his balance. This could avoid spamming, but someone could just buy votes. |

Enjoy your holidays Thanks I also want to thank you all for your great support, without you Gapcoin wouldn't be where it is now. I wish you all a Merry Christmas and a Happy New Year! |

need some updates:
1. wallet
2. site
for a start it will be enough.
crz just sent me the new logos for the wallet, unfortunately I don't have access to my compiler environment over the holidays, but I'll publish the next wallet release afterwards. I just made a few updates to the website, including the prime gap section. The is a new site containing new first known occurrence prime gaps which are not yet listed at http://www.trnicely.netI'll frequently submit the gaps listed there, so please don't spam Dr. Nicely. http://gapcoin.org/primegaps-length.phpps: I submitted the gaps only two days ago, and we already found 29 new records. |

You should send this to news@coindesk.com!
I already wrote them, once we got listed within the top-20, but I submitted the new records too. |

Hi there, I just want to inform you that Gapcoin just broke 544 records of first known occurrence prime gaps. The records are listed here: http://www.trnicely.net/gaps/g4k.htmlhttp://www.trnicely.net/gaps/g6k.htmlEven if we are currently a few of steps away from the world record of the highest merit primegap, I'm pretty sure Gapcoin can break some more records on those lists. All gaps found by the Gapcoin network can be download either as plaintext or zip from the website ( http://gapcoin.org/downloads.php). The files are updated every hour. I'm currently working on a method (involving Chinese remainder theorem) to improve the mining algorithm. (I'm not really sure if it can be applied to Gapcoin's mining algorithm, but I'll keep trying) I'll also working on a tool for parsing and processing Gapcoins prime gaps. (both will be released here, when finished) |

I just wrote cryptsy, and they "submitted the coin to their development team who will review it to see if it meets the requirements for addition to the Cryptsy exchange." |

I'm confused by what a gap and a merit is
You have two following prime numbers like p n=11 and p n+1=13. The gap is g n=13-11=2. The ratio of g n / ln(p n) is called the merit of the gap g n. Now why and if bigger merit is important i dont know. The average size of a prime gap increases with higher primes and is about ln(p n). In fact it its very trivial to find a gap with at least length n: For any prime number P, we write P# for P primorial, that is, the product of all prime numbers up to and including P. If Q is the prime number following P, then the sequence
P#+2, P#+3,...,P#+(Q-1)
is a sequence of Q − 2 consecutive composite integers, so here there is a prime gap of at least length Q − 1. Therefore, there exist gaps between primes which are arbitrarily large, i.e., for any prime number P, there is an integer n with gn ≥ P
The merit is the ratio of the size of a prime gap in comparison to the average size of a prime gap in the proximity of p. To find a gap with at least merit m, the average calculation amount is e^m primes. To sum it up it is easy to find long prime gaps, but it is very difficult to find prime gaps with a high merit. |
