Session text follows

<20:52:26> *** You are now talking in channel: "OpenHPSDR"

<21:05:07> "John - AJ6BC": You guys can check them out -
< http://www.altestcorp.com/ > - they have just doubled in size 
by purchasing the building adjacent to them.  Owner's name is 
Brian Seng - his e-mail is bseng at altestcorp.com - I have known 
him and have done projects with him for ~ 10 yrs.

<21:10:30> "John - AJ6BC": Regarding Jetson - is the CUDA GPU 
SDK open source?  I.e. - if I want to code up a CSI-2 camera - 
will I have source to start with or is this not 'open'?

<21:11:12> "John - AJ6BC": For Raspberry Pi - the BCM2835 does 
not have an open GPU - no available source for that CSI-2 camera.

<21:11:13> "Bill - KD5TFD": I don't know for sure, but don't 
think parts of the SDK are open source

<21:12:05> "John - AJ6BC": Hmmm.  I have posted a question on 
the CUDA/Embedded blog - no real answer (yet) - there was some 
discussion on making something open source-

<21:12:20> "John - AJ6BC": just not sure what that is (was) as 
far as real SDK source.

<21:12:24> "John - AJ6BC": (for the GPU)

<21:12:36> "Ken N9VV": USB-3 hub

<21:13:24> "Ken N9VV": Hub very useful if you want to plug in a 
FLASH stick in addition to your kbd/mouse

<21:13:47> "Bill - KD5TFD": plenty o hubs handy round here

<21:14:35> "Bill - KD5TFD": a 'case' for a jetson:

<21:16:17> "Bill - KD5TFD": anyone coming to CSVHF in Austin 
next week?

<21:17:35> "John – AJ6BC":
< http://www.csvhfs.org/2014conference/ > - nope - chance I will 
be in Houston though - but not for Ham unfortunately (family 
stuff...)

<21:17:36> "Ken N9VV": Jetson - two pieces of nicely milled plastic:
<  http://www.pugetsystems.com/  >

<21:19:10> "Ken N9VV": tegra Linux

<21:22:26> "John - AJ6BC": From an e-mail last Sunday:  I'm in 
Europe in holiday until August so may not have email access in some
places. In Paris at the moment and having a great time.  Phil....>

<21:23:53> "John - AJ6BC": 10MHz Winchester was mind-blowing in 
1983?2?

<21:24:30> "Mike - AA8K": I've still got an 8 inch floppy drive 
and core.

<21:24:33> "Bill - KD5TFD": pc/xt w/ 10 MB disk and 8087 got me 
thru undergrad days

<21:25:05> "John - AJ6BC": I loved my Atari-ST.  Used to run 
Fortran-77 on it.

<21:25:35> "Ken N9VV": Jetson Developers announced  Realtek 
RGL8188 WiFi module tonigh:
< http://elinux.org/Jetson/Network_Adapters  >

<21:25:39> "Bill - KD5TFD": I got my XT w/ an 8087 to learn APL 
... sadly that never happened

<21:26:34> "Ken N9VV": webpage has a list of all the WiFi 
modules that have been tested

<21:28:41> "Ken N9VV":
< http://en.wikipedia.org/wiki/Comparison_of_memory_cards  >

<21:28:52> "John - AJ6BC": Just in case anyone is interested:
< http://www.advantech.com/Support/TI-Evm/EVMK2HX.aspx >- 
(schematics there too) -
< http://www.ti.com/tool/EVMK2H > -
< 
http://www.digikey.com/product-search/en?x=4&y=14&lang=en&site=us&keywords=EVMK2H 
 > - cheaper on TI's estore.

<21:30:38> "Ken N9VV": There are some stunning CUDA demos. 
Wonder if they will run on the Jetson with CUDA enabled?

<21:31:22> "Dan - N4XWE": That is a good question.  Guess it 
depends on the drivers that are available.

<21:32:56> "John - AJ6BC": True color?  Distribute pixels per core?

<21:33:26> "John - AJ6BC": I was in the TI TIGA group once upon 
a time....

<21:34:03> "John - AJ6BC": Texas Instruments Graphics 
Architecture - we had the first GPU in spite of what nVidia says.

<21:34:26> "John - AJ6BC": Try an NP-Complete hello world.

<21:35:28> "Ken N9VV": CUDA Benchmark Project (dated to 2012!)
< http://forums.creativecow.net/thread/2/1019120  >

<21:36:48> "Ken N9VV": Amber 14 NVIDIA GPU benchmarks
< http://ambermd.org/gpus/benchmarks.htm  >

<21:37:14> "John – AJ6BC":
< http://infolab.stanford.edu/~ullman/ialc/slides/slides11.pdf > 
- man, you can find anything, correct?

<21:37:56> "John - AJ6BC": 73's.
