If you're uploading nearly 20 mbit/sec to them and they only have 0.3-0.5 mbit/sec upload (or worse, set their upload speed max in their BT client to 50 KB/sec or less) ...that is barely helping the swarm.[17:27:02] <davidk> Why the faster uploader should get the more income ?[17:27:31] <davidk> Can you imagine someone with 2x the upload broadband more big than the download broadband.[17:28:04] <davidk> Would he download at twice the speed you would get with 1x upload, 1x download ?[17:28:30] <davidk> Not talking about download.[17:28:35] <davidk> download speed.[17:29:06] <davidk> If we have virtually infinite download broadband.[17:29:47] <davidk> and you can upload at x kB/s[17:29:58] <davidk> would you get exactly x kB/s as income ?[17:33:02] *** tomaw has quit IRC[17:33:27] <Switeck> no, but the real world is too complex[17:33:44] <Switeck> the faster uploader should get more income *IF* they are uploading more to others[17:34:01] <Switeck> since ultimately extra upload to them "costs nothing" since they're passing it forwards.[17:34:54] <Switeck> the opportunity costs are lower uploading as fast to them as they have upload speed to upload to others...as opposed to uploading quickly to someone who only has 1/2 as much upload speed.[17:35:15] *** tomaw has joined #bittorrent[17:35:30] <Switeck> But this is from the point of view of the INITIAL SEEDER, which is not what the average joined-the-torrent-10-days-later download is.[17:45:11] *** Guest4310 has joined #bittorrent[17:59:10] *** goussx has joined #bittorrent[18:24:05] *** goussx has quit IRC[18:24:16] *** goussx has joined #bittorrent[18:26:10] *** jnpplf has quit IRC[18:32:34] *** Switeck has quit IRC[18:38:36] *** jnpplf has joined #bittorrent[18:40:23] *** Switeck has joined #bittorrent[18:48:50] *** goussx has quit IRC[19:00:08] *** goussx has joined #bittorrent[19:16:23] *** goussx has quit IRC[19:18:07] *** plavcik1 has joined #bittorrent[19:20:33] <plavcik1> hello, I need to compile bittorent from source code for OpenBSD platform, but I can't find URL for source code, Is that still available? if yes, whre please?[19:21:24] <TheSHAD0W> If you're talking about the original BitTorrent, it's in Python, which is interpreted. Install Python, then directly execute xxxx.py.[19:22:27] <plavcik1> thats clear, I need to find, where I can download .py code. (or I had to try unpack exe file for Windows)[19:26:09] *** goussx has joined #bittorrent[19:28:55] <DWKnight> plavcik1: you're looking for either another client like bittornado or you're looking for a version 5.x or older one[19:32:25] <plavcik1> I'm fine with older version, but I didn't find url to source code on bittorrent.com and bittorent.org sites[19:34:16] *** goussx has quit IRC[19:34:24] *** goussx has joined #bittorrent[19:37:41] <plavcik1> I have to disconnect, bye[19:37:51] *** plavcik1 has quit IRC[19:49:16] *** jch has joined #bittorrent[19:58:34] *** jch has quit IRC[20:06:29] *** goussx has quit IRC[20:10:46] *** goussx has joined #bittorrent[22:04:08] *** `rafi_ has joined #bittorrent[22:13:26] *** Switeck has quit IRC[22:14:28] *** `rafi_ has quit IRC[23:03:26] <davidk> geopolitics bittorrent[23:04:30] <davidk> Switeck : I wonder if mathematical stuff can describe the way a bittorrent networks works.[23:05:07] <davidk> And find on-the-fly optimization as the best solution to equilibrate the up/download rate, resulting in the fastest way for users to download a movie or whatever.[23:05:26] <davidk> It's an optimization problem, isn't it ?[23:18:08] <The_8472> it's more a game theory thing[23:18:35] <The_8472> trying to get a closed mathematical formulation of a bittorrent swarm will only result in simplifications that make the whole thing unrealistic[23:21:01] <alus> davidk: however if you still want to go that route, here's a steaming pile of garbage on the topic: http://www.dcia.info/documents/P4P_Overview.pdf[23:23:25] <The_8472> yeah, there is lots of research around bittorrent out there. it usually falls in one of two categories a) they validate what developers used as working assumptions anyway b) it has some shortcomings that make it's real world applications limited[23:24:16] <The_8472> *its[23:24:46] <The_8472> finding those that actually provide new, useful insight is hard
