If you want to make sure that your site can be manipulated agentically by Meta's Muse, do not block traffic from ASN AS32934, because if you did that, it might make it impossible for the Muse agents to reach your site.

More #FreeCADFriday now in Friday in my own time zone. I have a fan that I want to make a table stand for to use outside while operating #HamRadio. First I modeled the fan in a silly amount of detail, including the grill, which took some learning, and I'm still pretty sure I didn't do it in the best way! But I got it done.

Next I used that as a shape binder to model a case around it. But I have only one grill per fan, so I really need to have something to keep fingers out. I used the front grill to work out spacing between the bars, and I'm playing with the PolarPattern to work out how may radials I think I need; fewer is better for airflow, but enough to support the axial elements.

Ultimately. this will need some sort of stand and a way for the wires to come out to power it. That I'm still working on...

Yes, the rumours are true. RSE Line is now available in Orange for all of your field needs. See how I solder it up in my latest video here https://www.youtube.com/watch?v=91O2q1OpJNg Get yours at http...

@nprofile1q... Team 2mm banana connectors represent!

I use 3:1 or 4:1 marine heat shrink with adhesive. It stays in place, and is stiffer, so it protects better against solder embrittlement.

I use 2mm banana connectors for radiating elements, not just radials, and I put a loop of dacron twine on the female end to easily tie to my throw weight line. The marine heat shrink holds it in place. I also shroud the female end entirely in heat shrink which distinguishes it handily from the male end without needing a different color of heat shrink.

I use the same technique for links in linked antennas, too, with the same dacron twine carrying the load.

(For my elevated radials that are held up by tension, I used 4mm banana plugs for additional holding force.)

@nprofile1q... Whereas I generally like the GTK ecosystem and my GNOME involvement goes all the way back to being part of the team that first integrated GNOME into Red Hat Linux (as it then was). I don't think it's terrible.

From time to time I try KDE and keep discovering that it's not for me. No disrespect intended; I just prefer GNOME.

I don't think it's generally unhealthy; I am complaining about one particular exception, from my point of view. When I say "exception" I'm not making a claim of uniqueness, but I am saying that it's exceptional in my own experience.

If I weren't overall happy with it, I'd be using something else and my top post would never have been written, because I wouldn't have run into the nuisance.

It's the fact that I like the ecosystem overall that makes that post even possible.

You do you, we have different preferences.

Updated to Fedora 44, and discovered pretty quickly that middle click is disabled. ๐Ÿคฎ

Not a big fan of Jordan Petridis right now. The attitude in his pull request was not awesome. Next I expect GNOME will remove the ability entirely with the excuse that "nobody uses it" since that was also used as part of the excuse for disabling it by default, calling all of us who use it a "nobody" which is kind of disrespectful.

They didn't even add it to settings. The repair is not particularly discoverable.

For everyone else caught by this mess, the incantation is:

gsettings set org.gnome.desktop.interface gtk-enable-primary-paste true

This is amazing. EA1FUO has built nec2c into WebAssembly, and now you can do antenna simulations on your phone or desktop without depending on nec2c running on a server. You can also deploy it locally, and he provides instructions for how to do this on docker or bare, and you can run nec2c on the server if you like.

Takes seconds to simulate my inverted V, and it even displays updates on what it is doing while running the simulation. It then gives a 3d rendering that you can drag around to get a better intuition. As you hover your mouse over the model, it shows gain in dBi with elevation and azimuth.

Beautiful work!

I don't know where else he's active, but he's been posting about this on Reddit as he's been developing it:
