My miocrophone doesn't work. mod is me, Michael O'Donnell 18:33 ------------------------------------------- Joshua Gyllinsky Hi Everyone! 18:33 ------------------------------------------- Jerry Feldman Hi Michael 18:33 ------------------------------------------- mod just my iniitials, not moderator 18:33 ------------------------------------------- Kurt James, Did you want to give us an update? 18:39 ------------------------------------------- Bob Primak Hi folks. Bob P. here. 18:39 ------------------------------------------- epp epp (from the BLU list) 18:39 ------------------------------------------- Kurt I see Josh is here from Lovecraft Country... 18:40 ------------------------------------------- James Sure. Joining from Marbella, Spain. Just saw the link on Mastodon 😃 18:40 ------------------------------------------- Joshua Gyllinsky Hi Kurt! 18:41 ------------------------------------------- Kurt 😃 18:41 ------------------------------------------- Joshua Gyllinsky Ubuntu 20.10 updates maybe? and back ports what Bill said I think you can add it to a list if you use the apt auto purging 18:44 ------------------------------------------- epp CAn someone fix X11? 😃 18:53 ------------------------------------------- Jerry Feldman https://youtu.be/0SRfxmUxt4A 18:55 ------------------------------------------- Joshua Gyllinsky Is anyone here familiar with XPRA? I'm curious about specifying when to run GPU on local machine Versus when to work on the Server before forwarding. It seems to mostly do CPU rendering via MESA. Any suggestions on where to look? Its kind of like a fancy X11 forwarding tool I am using it with COMSOL for linux for Multiphysics sims thanks 18:59 ------------------------------------------- John M is there any sound, when does the meeting start? 19:01 ------------------------------------------- Joshua Gyllinsky @John M, there is sound 19:01 ------------------------------------------- Jerry Feldman There is sound we are all talking. Check your settings. 19:01 ------------------------------------------- Desktop Screenshare (Bill's) Chrome(ium) does a better job of requesting access to your sound hardware than Firefox. the three-dot hamburger menu has sound settings. Use of the plug-in instead of native browser mode may work better for sound. 19:03 ------------------------------------------- Joshua Gyllinsky To be fair though, no one is talking at the moment 19:04 ------------------------------------------- Brendan Kidwell (New York City) https://alphacephei.com/vosk/install 19:07 ------------------------------------------- Jerry Feldman Bill's in the cat house 19:08 ------------------------------------------- Desktop Screenshare (Bill's) Gwyn Kitteh remembers my first long-running series of WFH agile meetings featured a number of cats and a dog on the speakerphone so she'll come check it out and see if there are any kittehs talking. 19:11 ------------------------------------------- Bob Frankston Can you use two coral chips? 19:27 ------------------------------------------- Joshua Gyllinsky So there are ecology calculations for reoccurring sampled individual animals 19:36 ------------------------------------------- Desktop Screenshare (Bill's) Seriously disappointed "Squirrel" isn't a "Bird" category 😄 19:37 ------------------------------------------- Bob Frankston Lots of ground birds like Turkeys too. 19:37 ------------------------------------------- Joshua Gyllinsky North American Furry Acorn Birb 19:38 ------------------------------------------- epp Nice! 19:39 ------------------------------------------- Bob Frankston Your early solution offloaded to a second pi. 19:40 ------------------------------------------- Kurt Thank you.Seth... that was awesome. 19:44 ------------------------------------------- epp Thanks, Seth. 19:44 ------------------------------------------- Joshua Gyllinsky I've had difficulties getting the OBS Video4Linux virtual drivers to work correctly. I'd be interested talking with someone about that later/sometime 19:46 ------------------------------------------- John Abreau I tried to find instructions for the OBS virtualcam plugin a while back, but most of what I found was for Windows only, and the few Linux results seemed to be Ubuntu only, and I use Fedora. 19:49 ------------------------------------------- Desktop Screenshare (Bill's) MacGuffin and Marchitecture in same Presie, that's close to Bingo ! 20:04 ------------------------------------------- kk please share your slides 20:06 ------------------------------------------- Kurt Can we convince the FCC that any frequency is fair game? (under 1 watt) 20:06 ------------------------------------------- Bob Frankston https://1drv.ms/p/s!AglBpbKyzKIQkdEBm5qg82Y5-SwBpA?e=bgylOx 20:07 ------------------------------------------- seth birdbox slides https://1drv.ms/p/s!AhbUKzWaWF2olb92i0vInEfCCGlVUg?e=S1b76M 20:08 ------------------------------------------- Desktop Screenshare (Bill's) @Kurt - only if _all_ services are forced to digitial (or accept interference) . Army/Air Force are among those who would resist ... 20:09 ------------------------------------------- Shirley Dulcey @Kurt: power levels well under 1 watt can still interfere with licensed radio use 20:09 ------------------------------------------- Desktop Screenshare (Bill's) Argument by redefinition. 20:09 ------------------------------------------- Kurt Argument by EIRP definition This can be worked around by antenna design yes? 20:10 ------------------------------------------- Shirley Dulcey Try putting 1W EIRP on the GPS band and see how many friends you make 20:10 ------------------------------------------- Desktop Screenshare (Bill's) Yes, i said, if you ban non-spread-spectrum signals free access works ... there are incumbent services with more klout than ham radio with itnerest in maintaining reserved frequencies ... If we're all cooperating people we'd all be cooperating people ... winner argument never mind the IEEE ... if we're talking free access to any frequency the USAF is the elelphant in the room ? 20:13 ------------------------------------------- Kurt Ha! 20:13 ------------------------------------------- epp LOL 20:13 ------------------------------------------- Kurt Lost my audio 20:15 ------------------------------------------- Desktop Screenshare (Bill's) milliWatts ... absolutely .... beamforming and codespreading/demod is marvelous. stipulated. Spectrum auctions are tragic even if they got a Nobel prize ... stipulated But suggesting mandating spreading signal modulations and removing (amost) all allocations? pipe dreams. 20:16 ------------------------------------------- Kurt Ah, I'm back Thank you Bob... I have some ideas I will vet through our local HAMs before I send to you... Some of which are here... 20:17 ------------------------------------------- epp Thank you Bob. 20:17 ------------------------------------------- Bob Frankston As I said, we can work around the current rules by using packets with existing technology. The key is that these alternative approaches remove the economic value of owning frequencies and i think that is the path towards change. 20:21 ------------------------------------------- Desktop Screenshare (Bill's) "Confidential" on the slide template looks really good on YouTube 😄 I do like socks as model of entaglement ;-D 20:27 ------------------------------------------- Joshua Gyllinsky If one person looses a sock in one dryer... loses 20:28 ------------------------------------------- kk @Kiran can you scale your example to 128 bits? 20:36 ------------------------------------------- Kurt Kiran, I suspect we are years away from a production QC, but do we have a simulator academics can use (remotely I assume)? 20:40 ------------------------------------------- kk @Kiran that would mean breaking AES-128 @Kiran Thanks 20:42 ------------------------------------------- Desktop Screenshare (Bill's) right 20:42 Folks in EU should be given first semi-slot ! 20:44 ------------------------------------------- Kurt thank you Kiran 20:46 ------------------------------------------- Joshua Gyllinsky Thanks to all the presenters 20:49 ------------------------------------------- Kurt Will top tell you if is running on multiple cores? 20:51 ------------------------------------------- Desktop Screenshare (Bill's) well, top is probably single core but it will tell you if os is multicore 20:52 ------------------------------------------- Kurt Good point... sometime my top says I am using 399% of a quad core... 20:52 ------------------------------------------- Desktop Screenshare (Bill's) Exactly. 20:53 ------------------------------------------- GG what's the name of that speech-to-text package? 20:53 ------------------------------------------- Joshua Gyllinsky https://alphacephei.com/vosk/install 20:54 ------------------------------------------- Desktop Screenshare (Bill's) I had a Perf Admin call me and ask what stupid thing i was doing to use a full core, and i asked "ONLY ONE? I should be pegging all 4." (This was the beginning of a great collaboration.) 20:54 ------------------------------------------- John Abreau htop is a top alternative that does multicore found in a quick google search, i haven't tried it myself. yet. 20:54 ------------------------------------------- John Abreau just installed htop. looks pretty similar toregular top. htop is a top alternative that does multicore found in a quick google search, i haven't tried it myself. yet. just installed htop. looks pretty similar to regular top. multiple lines at top of term window, one per core. 20:57 ------------------------------------------- Michael I I use glances now, over top and htop. Saw it at BLU demo. 20:59 ------------------------------------------- Kurt We should try a code that is writen as an OpemMP vs. and OpenMPI "SMP" kernel 20:59 ------------------------------------------- Jerry Feldman https://nicolargo.github.io/glances/ 21:00 ------------------------------------------- Michael I It is written in python. 21:00 ------------------------------------------- Kurt Becuase you can address your processers as external CPUS in MPI... @Josh LOL... 21:02 ------------------------------------------- Shirley Dulcey Probably about time for me to go, things are winding down 21:05 ------------------------------------------- GG http://classweb.ece.umd.edu/enee359a.S2008/verilog_tutorial.pdf 21:11 https://readthedocs.org/projects/verilogguide/downloads/pdf/latest/ 21:11 ------------------------------------------- Joshua Gyllinsky @GG thanks! 21:12 ------------------------------------------- GG I also found this very useful: https://www.edaplayground.com/ 21:14 (for verilog) 21:15 ------------------------------------------- Joshua Gyllinsky https://8bitworkshop.com/ https://8bitworkshop.com/v3.6.0/?platform=verilog&file=clock_divider.v 21:16 ------------------------------------------- GG thanks, that's pretty neat. 21:19 ------------------------------------------- Joshua Gyllinsky did you see the vga sim? 21:19 ------------------------------------------- GG another thing that's similar-ish: http://digitaljs.tilk.eu/ 21:20 yes - surprising that vga can be coded in a page 21:22 ------------------------------------------- Joshua Gyllinsky I haven I haven't been able to get the VGA code to work on my Cyclone yet, but others have 21:25 ------------------------------------------- Kurt I have to log off but will put together a readahead vid for the 900mMhz discussion... 21:27 ------------------------------------------- John Abreau @Kurt sounds good 21:27 ------------------------------------------- epp If you select Toggle Tile View, it enlarges the active tile. 21:29 ------------------------------------------- John Abreau the issue is having it happen in the stream to youtube 21:30 ------------------------------------------- epp Then there should be an option for the moderator to enlarge that tile. 21:31 ------------------------------------------- GG in my view on jitsi if I click on a tile it full-screens that tile. I don't know if/how that translates to the livestream -- if the person livestreaming clicks a tile, does that not affect it? 21:31 ------------------------------------------- John Abreau jitsi doesn't really have a moderator role 21:31 ------------------------------------------- epp moderator - or whomever controls the meeting 21:31 ------------------------------------------- GG but someone clicks the "livestream this" button, no? 21:32 ------------------------------------------- John Abreau that's what i meant; jitsi doesn't have a designated user who can control the meeting 21:32 ------------------------------------------- Jerry Feldman jitsi is really a peer to peer. There is no 1 person who controls things. 21:33 ------------------------------------------- epp Bad Jitsi. 😦 21:33 ------------------------------------------- Jerry Feldman No, you can set jitsi up with a moderator. But you would need a passwords. 21:34 ------------------------------------------- John Abreau we should try that next month; 21:34 ------------------------------------------- GRG but today, one person clicked "start livestream", yes? 21:34 -------------------------------------------
