[00:04:31] <_rafi_> alus, do you remember if the tcp overhead you have embedded into uT calculation in the first inplementation of bt.calc_overhead was (at the time) a constant of about ~5% ?
[00:04:52] <_rafi_> *implementation
[00:05:57] <alus> it was not implemented as a constant
[00:06:51] <_rafi_> ? but around that order ?
[00:07:51] <alus> you tell me :P
[00:07:58] <_rafi_> this number is what I remember from the past
[00:08:03] <_rafi_> :)
[00:08:23] <alus> ok
[00:09:00] <_rafi_> (I am s not so sure about it though...)
[00:10:18] <alus> because it is not implemented as a constant?
[00:11:19] <_rafi_> no, because of the long time that has passed since... ;)
[00:14:35] <The_8472> i assume you're just counting writes + adjusting for nagle's?
[00:16:05] <_rafi_> ha ?
[00:17:24] <The_8472> count socket writes. if it weren't for nagle's algorithm then 1 write = 1 packet + 1/2 ack
[00:18:09] <_rafi_> never saw the code...
[00:18:53] <_rafi_> ...packet size can vary
[00:18:57] <The_8472> well, i'm just guessing, based on how i'd do it

[03:03:26] <DeHackEd> dunno. I surf with noscript
[03:03:32] <alus> I think that's the deal
[03:03:34] <DeHackEd> though how javascript is able to do that I'll never know. can't it only open HTPT urls?
[03:03:39] <alus> java
[03:03:46] <DeHackEd> java != javascript
[03:03:57] <alus> but javascript can control java, and java can connect to irc

[07:49:55] <burris> if I add twice as many trackers to my torrent, I'll download twice as fast, right?
[07:50:23] <charles> burris: you're joking?
[07:50:26] <burris> of course
[07:52:09] <burris> it's like the guys on etree, now that 4 and 8 track recorders are portable and affordable, seeing recordings made with two, three, or four stereo pairs combined in software to make one craptacular mix... after all, if two mics is good, four mics must be twice as good!
[07:52:35] <alus> combined. ouch.
[07:56:12] <burris> http://bt.etree.org/details.php?id=530329 <-- this has the info but you gotta click 1-25 to see the earlier comments
[07:57:40] <burris> I couldn't believe how many tapers were at phish on halloween, I thought livephish.com would discourage most of them, but then I realized that I listen to pretty much nothing but taper tapes and not the ones that phish sells, so I guess I'm glad someone is still willing to do it
[07:59:46] <burris> for that guy, there is apparently a difference between "timing" and "phase"
[08:00:41] <burris> finally, it never ceases to amaze me that people will spend $6k on nice mics and a pro deck then fail to spend $100 for an audio engineering textbook
[08:03:38] <chelz> easier to spend money than to learn
[08:04:26] <burris> depends on whether you have money or not
[08:29:05] <charles> you see a lot of that on older shows too, where there are several crappy sources, and people try to merge them together to make a single good source
[08:29:12] <charles> usually it just sounds like several crappy sources melted together
[08:35:22] <chelz> there probably are some algorithms that experienced people could use to make a better quality recording

[10:45:16] *** Koper has joined #bittorrent
[10:57:34] <alus> haha, sounds
[10:58:13] <alus> there is a difference between timing and phase, but when everyone is just pointing there mics at the stage it seems unlikely you would have a phase difference
[10:58:34] <alus> unless they are surrounding it
[10:59:21] <alus> and for some reason unable to point their mics correctly
[11:05:45] <burris> you get phase difference for any frequences whose wavelength is shorter than the displacement between the mics, so for two inches thats everything above 6.75 kHz
[11:06:25] *** KyleK_ has quit IRC
[11:14:48] *** goussx_ has joined #bittorrent
[11:17:57] <alus> burris: unless the mics are placed perfectly in a circle, I guess
[11:18:32] <alus> a circle around the sound source
[11:21:15] <alus> pressure waves radiate spherically, and phase should be position of the membrane of the mic. so anything equidistant from the center pointed exactly at the center should be hit with the same pressure wave at the same phase
[11:21:34] <alus> and at the same time
[11:22:15] <alus> but that also assumes there is a perfect center, which would be pretty odd at a concert
[11:25:00] <alus> timing differences do have phase problems when you try to combine the signals, but as you said that's not linear across all frequencies
[11:25:46] <alus> so it's usually called a timing problem not a phase problem, since shifting the signal in time should fix the phase issues. adjusting the phase of all frequencies equally could not solve it
[11:25:51] <alus> which he seems to say he does
[11:27:32] <alus> maybe those mics off to the right that he mentioned weren't aimed correctly?
[11:27:44] <alus> why use them :/

[11:33:04] *** goussx__ is now known as goussx
[11:36:10] *** goussx__ has joined #bittorrent
[11:36:35] <burris> the problem is that you're recording not one but two sound sources, left and right mains...  when you get closer to one you get further from the other, then time of arrival differences between the two sound sources are permanently convolved in each channel
[11:36:55] <alus> yeah
[11:37:17] <alus> that's kind of a huge problem here I image, unless you're so far away you can't hear anything anyway
[11:38:15] <alus> if only they would pulse an inaudible but recordable identifier of somesort, you could adjust the channels after recording

[12:07:57] <kjetilho> why bother with mics rather than jack into the soundboard?
[12:11:07] <burris> soundboard doesn't sound very good except in the largest venues, and the bands that play those venues don't let you jack into them (or they stop by the time they get that big) so you still need mics on the stage to get the stuff that isn't in the house mix, like screaming guitars
[12:16:49] <burris> there's other reasons too, sometimes you want the audience, sometimes the band jumps off the stage and plays acoustic instruments in the crowd, and a good audience recording can really take you there
[12:19:21] <burris> frequently I record small bands in small venues where not every instrument is mic'd
[12:22:58] <kjetilho> ok
[12:24:48] <burris> also, some venue owners are huge pricks that try to charge you hundreds of dollars to patch out of the board and god help you if you're at a union venue
[12:25:41] <burris> that's why you need a "stealth" mic setup too, because sometimes the venue wants to rain on your parade even though you've got the full support of the band
[12:26:22] <burris> some bands actually have "no see no enforce" policy too
[12:26:35] <kjetilho> yeah, but I was thinking in the context of taper friendly bands
[12:26:49] <kjetilho> like Phish
[12:27:24] <kjetilho> surely the venue won't try to limit taping at a Phish concert?
[12:29:27] <DWKnight> venu owners are pricks like that
[12:30:17] <DWKnight> unless phish has a contract in writing with them saying the owner won't interfere, some of them will
[12:30:55] <burris> oh I've had all sorts of trouble trying to bring my gear into phish concerts because of uinformed security... usually you try another entrance and you're fine... but it can be a real hassle with smaller bands in theaters with only once entrance...  I had to have the MMW soundman carry my gear in for a concert in Seattle a few years ago.
[12:32:07] <burris> also, phish stopped allowing board patches in '93 and I stopped taping them when they started selling the soundboards (exactly as you said, "why bother?")
[12:34:01] <burris> phish definitely makes the venues contractually obligated to allow the taping
[12:34:35] <kjetilho> I think this is a very cool concept for more casual fans like me: http://www.playedlastnight.com/
[12:35:00] <kjetilho> I mean, I'm not fanatical enough to care about a lot of different live sets
[12:35:41] <kjetilho> but it *is* nice to have a recording of the exact concert you went to
[12:36:10] <burris> it's also nice to listen to it on the drive home :-)
[12:36:39] <burris> and if you got totally wasted at the show, you hear it again for the first time!
[12:39:53] <burris> once phish did a surprise performance on a flatbed truck as they drove through the parking lot / campground at 4 in the morning, having a portable mic rig sure came in handy that time
[12:46:27] <burris> here's one of my favorite recordings if you're interested, I'd just DL disk 2 (files with "d2" in them), http://bt.etree.org/details.php?id=531624
[12:46:59] <burris> I'm pretty sure that the Mercy Mercy Mercy from this show is the first or second thing ever transferred with BitTorrent
[12:48:10] <burris> so maybe just dl that one ;-) d2t07
[12:58:02] <kjetilho> what/who is MMW?
[12:58:46] <kjetilho> doh, read the link :)

[20:55:30] <DWKnight> torrent magnet or gnutella/ed2k-friendly magnet?
[20:55:33] <lucapost> with bittorrent info hash
[20:55:51] <lucapost> btih
[20:55:53] <DWKnight> you need to make a torrent of the files first for that
[20:56:44] <lucapost> yesterday I found rhash
[20:57:06] <lucapost> http://rhash.anz.ru/
[20:57:39] <DWKnight> information from that could be used to make gnutella/ed2k-friendly magnets
[20:58:00] <DWKnight> but not btih ones
[20:58:08] <lucapost> :(
[20:58:30] <The_8472> you just need the .torrent file and some tool that can spew out the infohash... maketorrent maybe?
[20:58:43] <The_8472> well, there are some cli tools that can give you the infohash
[21:02:30] <lucapost> I do not quite understand the theory of torrent magnet, the magnet is for my files or for .torrent previusly?
[21:02:51] <DWKnight> the magnet is effectively for the .torrent
[21:03:00] <DWKnight> the .torrent is then for the files

[21:06:48] <DWKnight> but a file's BTIH and SHA1 will pretty much always be different
[21:08:02] <DWKnight> in fact, I don't think it's possible for them to ever be the same
[21:09:09] <The_8472> it is possible, though you'd need a few universes to calculate that
[21:09:30] <DWKnight> realistically, it won't happen

[21:37:15] <Switeck> DOH! XD
[21:37:22] <Switeck> so did the tracker get fixed?
[21:37:22] *** kwinz2 has joined #bittorrent
[21:40:15] <charles> Switeck: yes.  it's one of the trackers that popped up to take the place of one that went down, and in the early days they accepted .torrent files from the previous tracker... but didn't handle the private flag on them
[21:40:49] <Switeck> br0k3n!
[21:41:31] <Switeck> The tracker adding a private flag to me seems crass...pulling public torrents into private trackers.
