Sunday June 21 2020 from 11am to ? 

Pi news:  

Pi foundation announced the 8GB version of the Pi 4 https://www.raspberrypi.org/blog/8gb-raspberry-pi-4-on-sale-now-at-75/
So this means now we need a 64bit OS.  Recall that Raspbian is 32bit only.  I hadn't realized myself but Raspbian isn't actually 
put out by the Pi foundation.  It is actually a 3rd party.  https://www.raspbian.org/FrontPage
So the foundation is creating their own called Raspberry Pi OS https://www.raspberrypi.org/forums/viewtopic.php?f=117&t=275370
which has a 64bit image (in beta).  
Newer Linux kernels have much better support for Arm cpu so there is not as much need for a heavily modified distro.  
Ubuntu has official 20.04 server for the Pi https://ubuntu.com/download/raspberry-pi You could probably install Ubuntu 
server then sudo apt install whichever desktop you like.  (I haven't tried myself, yet)

Pi foundation announced USB boot firmware for the Pi 4.  (beta, again)  Previously USB boot was only for 
Raspberry Pi 3B, 3B+, 3A+ or a Raspberry Pi 2B v1.2. You can find the documentation here: 
https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711_bootloader_config.md
(Scroll down the page to see USB)  Note that it is for USB mass storage device.  If it is detected to be 
USB Attached SCSI  This is another thing I have to try out!

New official Pi hardware:  New camera module that they are calling HQ (for High Quality)  
It has an 12.3mp sensor and standard screw for tripod mount.  It doesn't come with a lens.  
For that you will have to provide your own.  It takes C-mount lens and also comes with CS-mount adapter.  
Now, I don't know much about photography and cameras, so I may be wrong in what I say.  
So I understand that C and CS are common for Closed Circuit cameras (CCD) they both use the same thread (1 in dia.) 
but the CS holds the lens farther from the sensor.  https://www.raspberrypi.org/blog/new-product-raspberry-pi-high-quality-camera-on-sale-now-at-50/
I've ordered one of these and should have it by the meeting, but I forgot about the lens though.  Just ordered the 
official telephoto lens and hopefully it makes it by Sunday.  But I have a couple that I got off Ebay and one I found on the sidewalk.  
https://photos.app.goo.gl/AYSJ2RizU4UXC8os6  The black ones are from Ebay both C-mount.  Both have control cabling.  
Small one has a cut cable and looks like 4 conductors.  Large one has an 8 pin DIN.  
Silver one I found walking around. The thread is 1 1/4 in but I found that the inside thread accommodates the C/CS.  So 
maybe an adapter is possible.  The lens says "Sony TV Zoom" But it doesn't appear to be a Sony standard thread mount 
(or of any other standard that I can find)  https://en.wikipedia.org/wiki/Lens_mount
