That's a big fat 'no', Amazon

Quoting from a recent email:

Amazon Sidewalk is a shared network that helps devices work better. For example, if your device loses its wifi connection, Sidewalk can simplify reconnecting to your router and help set up new Echo devices. Sidewalk can also extend the coverage for Sidewalk-enabled devices, such as Ring smart lights and pet and object trackers, so they can stay connected and continue to work over longer distances.

When enabled, Sidewalk uses a small portion of your Internet bandwidth to provide these services to you and your neighbors. This setting will apply to all of your supported Echo and Ring devices that are linked to your Amazon account.

Sidewalk is coming to your Echo device later this year, but you can disable this feature at any time from the Amazon Alexa app.

Call me crazy, but this sounds like it defaults to enabling this bandwidth-sharing “feature” on all supported Echo devices, unless you remember to shut it off after it goes live. It currently shows as off in the app, but also “not available yet”. Given that they turned on calling functionality without notice (leading it to call me on my cellphone when I said “porch light on”), I have no reason to trust them.

Note that there appears to be no way to determine what “small portion” means, or who you are currently providing “these services” to.

No Cura for you!

Tried to use Cura 4.8.0 with the settings I linked earlier. Had to abort the print in a real hurry because the leveling probe came down as it started to print the skirt. That does not work.

Despite its flaws, MatterControl looks like the best slicer for me right now. What flaws, you might ask? A completely non-standard UI, an actively user-hostile mouselook implementation, a habit of auto-loading a part that you last looked at two weeks ago, no retention of window location and size, no new Mac builds since April (Windows = 2.20.11, Mac = 2.20.4, Ubuntu = 2.19.10), and it pegs a CPU core when it’s idle. My fans spin up as soon as it launches, even if I never do anything.

The release notes promise a Mac version of 2.20.11, but “coming soon” was two weeks ago. I was able to successfully adapt the cursory build instructions they supply on Github, only to have it blow chunks on launch:

WARNING: The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all

        External Debugger Dump:
Abort trap: 6

I wonder how they got it to work back in April, but since the source/build directory is over 24 GB (not counting the Mono and Nuget installs), I’m not going to futz with it any further. I’d like it to work, since they’ve added some nice features, but the Windows version runs fine under VMware. And on the old Surface Pro 2. And the old Asus gaming laptop. And the not-quite-as-old Asus gaming desktop.

So I’m good.
