m44 m106

 An all nighter. Can't remember the last time it was cloud/wind/storm free all night. Nothing went well. Of particular note, one the usbs on the mount -the little blue thing in the socket- decided to finally work itself loose, rendering the camera inoperable. How long does it take to debug something like that? In the dark and with with the telescope 15m away...

rustdesk

To install the -more-Wayland-friendly-by-the-hour- nightly version:
1. Grab it from here.

2. Remove the old version

sudo dpkg -r rustdesk

3. install the new version e.g. for today's nightly:

sudo dpkg -i rustdesk-1.4.5-x86_64.deb

It should look something like this:
Selecting previously unselected package rustdesk.
(Reading database ... 305573 files and directories currently installed.)
Preparing to unpack rustdesk-1.4.5-x86_64.deb ...
Failed to stop rustdesk.service: Unit rustdesk.service not loaded.

stem/rustdesk.service'.
Processing triggers for desktop-file-utils (0.28-1) ...
Processing triggers for hicolor-icon-theme (0.18-2) ...

4. Launch:











5. If you haven't already, allow rustdesk clients through the firewall:

sudo ufw allow 21114:21118/tcp
sudo ufw allow 21116/udp

6. Configure (I think for both client and server...?):




















7. Unlike me, don't forget to actually start the service on the box you want to control😉

SASPro layer mask

We have three images:

A sharpened crab      crab m1-seti-hp-2_01
A denoised crab      m1-seti-hp-2_01_duplicate
A crab mask      Mask

 We want the sharp crab on the denoised background. Using the layers module:

  •  drop the sharpened on top of the denoised
  •  apply the mask to both 
  •  invert the mask of the denoised

That's it. BUT... don't forget to Merge the layers, e.g. Merge --> Push to View

hp z420 firmware

It's something to do with Microsoft and UEFI. No idea what it does, but evidently, it's important. So...
