Well I had tuned in early than every one to check the camera.<br>
It worked ok.<br>
But with Jitsi you need to use Firefox in the latest version or <br>
Chromium.<br>
I tried to use SeaMonkey but it is not compatible with Jitsi.<br>
Using is learning.<br>
<br>
One thing I think is very important is to do your updates before the<br>
meeting as we got to see someone running their updates on the Jitsi<br>
screen. Also asap you should get a name and at least an initial up<br>
on the Jitsi screen.<br>
<br>
On mine using Firefox 78.0.1 I set up in the Preferences that Jitsi was<br>
allowed to use the camera and microphone but while at the meeting i had<br>
go to my system volume control and increase the response from the<br>
microphone so that people could hear me. After the first adjustment<br>
I had to turn down the response as other people reported some extraneous<br>
noise.<br>
<br>
Further in the lower lower right hand corner of the Jitsi connected <br>
screen<br>
are three very small vertical dots. Clicking on these lets you add a <br>
name to the<br>
screen you are seen on then if the bandwidth is low you can reduce the video<br>
quality and you can put your background out of focus. Very handy for those<br>
of use with less attractive backgrounds.<br>
<br>
We were graced with the mutual presence of John S.; myself of course:<br>
Al Waley who was trying to debug a problem;<br>
Akkana P. from further east. She left early for outdoor activities;<br>
Thomas;<br>
Ken S. who had his own problems and left early;<br>
John ?<br>
Michael Paoli who seemed to be having camera problems and was sharing<br>
a terminal screen with us;<br>
and Rick M. who came late but was still there at 1 PM when I left.<br>
<br>
The main topic initially was the use of the equipment we have in <br>
front of<br>
us. That is how I learned about the 3 vertical dots and their utility.<br>
<br>
Then we talked about the fireworks which the unqualified were <br>
shooting off<br>
yesterday evening. I live in downtown San Francisco and we heard loud <br>
booming<br>
and at hand either gunshots or firecrackers. And I was up after <br>
midnight listening<br>
to this and other noise including sirens in the night. Rick was <br>
distressed because<br>
rockets were being used which is very dangerous in this dry weather.<br>
<br>
Lots of other people had stories about their neighborhood and even <br>
Akkana<br>
Peck in the Mid-West(Nebraska if I have that right) was shocked at the <br>
amount of<br>
fireworks available there. When I turned on the TV news at 6 AM they showed<br>
the pall of smoke hiding Oakland and the haze of smoke obscuring details <br>
of the<br>
East side of San Francisco. In addition to this we have learned that <br>
the smoke<br>
from firework is really bad pollution, unhealthy for living things and <br>
people.<br>
I think that is a shame because I remember the smell of the fireworks from<br>
early youth and now to learn it is poisonous. Bye-bye nostalgic explosives.<br>
<br>
Next topic was what are we doing during our Shelter At Domicile or <br>
SAD days.<br>
One of the attendees, Thomas, it may have been was happy to discuss <br>
exactly what<br>
he does as a Computer Sciences teacher from Kindergarten thru 8th grade and<br>
he has been trying to get computers refurbished to hand out to kids whose<br>
families are suffering computer shortages at this SAD time.<br>
<br>
We indulged in some reminisces about how much we learned or did not<br>
learn during our own school days. I for example learned to do interpolation<br>
on a slide rule though I never mastered the abacus. Nor did I retain a good<br>
hold on Calculus.<br>
<br>
I myself have been playing lots of Angband. This is a dangerous habit<br>
as I forget to eat and drink when playing which leads to gorging and<br>
dehydration. I am playing on MX Linux running in Virtual Box on my<br>
PCLinux on the Dell E6540 from which issue all the redundant verbiage<br>
you get to glance at from time to time.<br>
<br>
From there it went to discussion of various software, and a site <br>
that Rick<br>
M. is trying to learn more about.<br>
<br>
I suggested because my sound was not clear, that Rick should post <br>
to the<br>
LUG list and see what people with time on their hands can do. I am sorry<br>
but I was not able to to determine exactly what Rick was interested in <br>
at that point.<br>
<br>
Anyone attending the meeting is free to correct my omissions or<br>
incomprehension of the activities and asked to do so asap so that the<br>
membership not in attendance will not be mis-informed any longer<br>
than necessary.<br>
<br>
Next meeting should be on Sunday, August 2, 2020.<br>
