QGroundControl Keeps Saying UDP Ports are in Use/Connected Despite not Showing Vehicles

I am running two SITL instances of PX4 and trying to view them on the map of QGroundControl (QGC). It worked once and then every time after, QGC says those ports are in use or already connected. I’ve tried:

  1. ps killing QGC
  2. disabling UDP auto-connect. Note, I had to do this in the first place to allow offboard control on 14540/14541, the default Mavlink ports of the SITL. Currently I’m trying to connect to 18570/18571.

Also, the comms links don’t seem to be editable after creating them. My next step is to try an older version of QGC. Please help.

Taking Recommendations: Old School 1990s Sushi Bar (Non-Omakase)

Hi friends, can you recommend some old school sushi places that do not make modern rolls, do not do omakase, and use rice vinegar in their sushi? I’m really looking for something that might have been around in the 1990s or early, where the menu is simpler. And, the chefs rely more on fish quality and balancing flavors rather than infusing new flavors. Does this make sense? Like an old school sushi bar. The rules say this is commonly asked but I didn’t see this specific request. Mostly, omakase.

Bots can’t make threats or respond to threats in kind. That’s one way of determining who is a bot.

Arguing online, I realize that bots don’t respond to threats nor do they ever make threats of their own. I think this is a pretty good way of determining whom is a bot or not. This is likely because of their internal safeguards.

Laplace Presenting a Cannonball Design to Napoleon: “How Europe Was Won”

This painting depicts the historical relationship between astronomer and mathematician Pierre-Simon Laplace and Napoleon. The work is meant to depict the relationship between technology and power. Napoleon, an artillery specialist, invested heavily in military technology which would pay dividends during the Napoleonic Wars. During his life, he would befriend Laplace and eventually appoint him to the position of Minister of the Interior, where Laplace would only serve for several weeks. The cannonball in the center is meant to be the focal point. If I were to change anything, I would put the globe behind the ball for more effective symbolism.

Brazier to Hold Ice in Front of Fan to Cool Air While A/C Is Broken

I left the supports on to distribute the center of mass. It actually works pretty well. The other room is much hotter despite it being darker and having a fan.
