20:16:09>  *** You are now talking in channel: "OpenHPSDR"
21:13:29> "Ken N9VV": Thank you Warren for all you are doing to 
advance our enjoyment with Hermes
21:14:07> "Warren - NR0V": Your welcome Ken, it's fun for me 
(most of the time at least).
21:15:48> "Bill - KD5TFD": bleeping tnc costs more than the 
computer?!?!?
21:16:08> "Jeremy - NH6Z": Yeah, and the computer is assembled, 
the TNC isn't!
21:16:26> "Jeremy - NH6Z": http://www.tnc-x.com/TNCPi.htm
21:17:01> "Jeremy - NH6Z": But still cheaper than a KPC-3+ by 
itself, and you get a computer in the deal!
21:17:18> "Bill - KD5TFD": ya -- $40 seems pretty reasonable
21:17:56> "Bill - KD5TFD": put a new version number of some sort 
on it
21:18:20> "Bill - KD5TFD": always a bad thing to have the same 
version num on 2 different things imho
21:20:13> "Bill - KD5TFD": the old 1 line of code change !
21:24:52> "Bill - KD5TFD": spec creeep ... never!
21:26:38> "Bill - KD5TFD": dropped packets as in sequence number 
hits?   Is that on your direct wire connection?
21:30:41> "George - K9TRV": got to go!  C U next week
21:30:54> "Dave - KV0S": &3 George
21:30:59> "Warren - NR0V": 73 George!
21:33:36> "Jeremy - NH6Z": Although everyone's all excited about 
the BladeRF with it's USB 3.0 interface.
21:33:54> "Ken N9VV": In the olden days there were "optimizd 
stacks" for TCP/IP/UDP
21:36:49> "Ken N9VV": With Giant MTU (8K?) do you get a larger 
"payload" across the net?
21:37:03> "Bill - KD5TFD": don't think we use large mtu's
21:37:16> "Jeremy - NH6Z": Jumbos are problematic in a large 
number of ways.
21:37:24> "Bill - KD5TFD": you should get higher thruput w/ jumbos
21:37:26> "Jeremy - NH6Z": I don't know of many consumer-grade 
pieces of gear that support jumbos.
21:37:41> "Bill - KD5TFD": but my understanding is they don't 
got thru most lower end switches well
21:37:55> "Jeremy - NH6Z": We'd need to design the openHPSDR 
protocol to deal with jumbos.
21:38:26> "Bill - KD5TFD": we conciously decided to no use jumbo 
frames when we started
21:38:37> "Bill - KD5TFD": c /to no/to not/
21:38:53> "Jeremy - NH6Z": I think I recall that when we were 
doing protocol design.  Too little support, even on enterprise 
and carrier grade gear.
21:39:18> "Bill - KD5TFD": ya -- that sounds familiar
21:39:24> "Ken N9VV": Thanks Jeremy - that is a mystical area of 
the net to me 21:40:09> "Bill - KD5TFD": don't think it helps 
the pc much ...helps network traffic
21:40:19> "Jeremy - NH6Z": You also run the risks of fragmenting 
packets and such.  WiFi doesn't support Jumbos IIRC.
21:40:39> "Bill - KD5TFD": we will nbot be doing gigiabit over 
wifi anytime soon I'd suspect
21:41:01> "Ken N9VV": ah --- 802.11xyz -- too easy to forget 
those restrictions.
21:41:43> "Jeremy - NH6Z": 802.11ac is supposed to be pushing at 
least a gig.
21:42:10> "Bill - KD5TFD": does it actually reach that in the wild?
21:42:42> "Ken N9VV": That rascall KD5TFD has 802.11a running in 
his QTH!! 21:42:45> "Jeremy - NH6Z": Not very much is in the 
wild yet, but the encoding is good like 802.11n, so I'd expect 
to see it reaching things.  It also depends on configuration, 
with the number of channels you're using.
21:42:53> "Jeremy - NH6Z": 802.11a != 802.11ac
21:42:56> "Bill - KD5TFD": I do have a running
21:42:57> "Bill - KD5TFD": not ac
21:43:08> "Jeremy - NH6Z": 802.11a < 802.11n
21:43:19> "Bill - KD5TFD": I've got a b and g networks here
21:43:23> "Jeremy - NH6Z":

21:43:57> "Rick - VE3MM": 73 fellows
21:43:58> "Ken N9VV": Cheers Phil
21:45:37> "Ken N9VV": XYL "AppleTV" running at 802.11n
21:46:40> "Ken N9VV": Working Set Size in Task Manager column
21:48:00> "Ken N9VV": Resource Monitor separate display (detailed)
21:48:59> "Ken N9VV": ts3client on Win-7/64 = consistent 55,324

21:55:29> "Jeremy - NH6Z": I'm pretty nazi about doing static 
buffers in a lot of my Mac/iOS code and things are pretty stable 
at that point in time.  Instruments are really nice to see what 
objects you're freeing and such.
22:00:47> "AJ6BC": PC Lint is your friend.
22:01:28> "Warren - NR0V": 73, dinner is ready here.
22:01:37> "AJ6BC": 73
