I ordered an X1 carbon from Lenovo with Fedora preinstalled.
https://www.lenovo.com/us/en/p/laptops/thinkpad/thinkpadx1/thinkpad-x1-carb…
It seems that they have the hi-res screen offering with the camera that
previously did not have support. It was a known issue for at least two
years to avoid that hardware configuration. It looks like it is
supported now!
Lenovo has 45% discount promotion on their site!
I configured the system with 64 Gig ram and 2 TB storage with the
2880x1800 screen.
The "estimated" delivery is Feb 1.
I have the 1st gen X1 Carbon and it has been a great machine!

Anyone played around with pipewire. I was just going to do some pacmd stuff on one of my recent Fedora 38 installs when I found out I am actually running pipewire-pulse instead of pulseaudio. It's suppose to be a seamless dropin for pulseaudio, but pacmd doesn't seem to see it.
The man pages and online documentation for pipewire seems a bit sparse.

I'd like to thank Brian for hosting the group meeting at Kupros last night.
It was supposed to be mostly social, but we ended up talking a lot of Linux. He mentioned that his new laptop seemed to have many options for the core configuration and we started to discuss how this was possible and might have gone off the deep end :)
We looked at some of the details of the C code for the navigation app and it was interesting to see the API's for accessing the sensor data. I hadn't played with that stuff for quite a while. We discussed the ease of accessing sensor data provided by a phone vs usb add on.
And the happy hour snack and beer weren't bad either.
We are shooting for being back at BelAir next month.

Hi Everyone,
The Raley's room is booked for January, so I decided to schedule a social
back at Kupros. Sen said he wanted to do a dry run of his embedded video
player. The last I heard back from him was late December and we are now
a week away.
Raley's Natomas has a room, yet I do not have a confirmation, so I am
not going to schedule something that is uncertain.
Social at Kupros on 21st St. is what I decided.
1217 21st Street

See you there!

Thanks!!
I found an Intermac 15 used on ebay. Bought it. I'll give it a try. I knew things like this existed, but I couldn't find it.

Found it. It is called an astronomical time switch.
Mine is the RT-200-I Made by Watt Stopper. But it is a few years old.
The -W version is available on amazon:

I hope you find this entertaining.
I have a very simple problem. I have a secondary structure on my property some distance from my house. It has a light that I want to come on sometime after sunset and turn off sometime before dawn.
There are a few issues.
1. The light is visible from the road, so it should look nice. Adding a socket with a day night sensor isn't possible. It won't fit inside the current lighting fixture.
2. The WiFi from the house does reach this structure, but it isn't very strong. My laptop can pick it up just fine, but the Shelly home automation switch I bought doesn't see it.
3. I have an extra phone that I use only for 2 factor authentication and a few other minor uses. I have a $10/month plan for that phone.
Note: The Shelly is installed. It can't see any WiFi, so it won't let me set up a schedule because it can't see a clock. Not withstanding the fact that I could tell it what the time is and even $0.20 chips have a reasonably accurate clock. We aren't flying planes or running nuclear reactors here. But it will let me tell it how long to wait after I turn it on to turn it off. This uses a clock, but I guess it slipped through. It's from Romania. I manually turn the light on every evening.
Plan 1
Move the second phone to the secondary structure and just use VNC to get any messages. Turn on the hot spot and have the Shelly get the time from that.
Result: I abandonded this plan when I couldn't VNC into the phone from the world. Lo and behold, this only works if you access the phone using WiFi. Since I want to use the hotspot, this means being connected to the phone's hot spot. Which means I have to be there, which defeats the whole purpose.
Plan 2
Set up my rPi on the hot spot from the phone. Use a remote ssh tunnel to access the rPi and then access the phone.
Result: The remote tunnel is blocked. I only did some brief reading, but you have to do some packet inspection to do this.
Plan 3
Use the slow network from the house to contact the rPi on a second external and good antenna. Use the rPi's native antenna to contact the phone.
Result: This works. But it is incredibly slow. The clock on the phone that I see when using vnc updates every 5 minutes. But despite this, it seemed pretty stable. Not really workable though.
Note: Although an ssh remote tunnel won't work, sshfs apparently will. I wouldn't have guessed that.
Note: Devices that are using the phone's hot spot can't see each other. They can only see the phone. This would mean that if I connected the Shelly to the hot spot, I wouldn't be able to see it from another device, like the rPi that I can talk to from my house. However, the phone can see all of the connected devices. And the rPi can VNC to the phone.
Next plan
Connect the Shelly to the hot spot. That should give it a clock and I should be able to schedule it using the phone. If I am away and need to make a change I should be able to use the rPi to VNC headlessly to the phone. Then I am thinking screen shots requested by the slow connection and forwarded to the sshfs share over the hot spot. I'll have to make sure I set the Shelly up with a static IP, or I'll never find it, since the phone, the only thing that could see it, won't nmap or tell me what is connected to it.
Thoughts
Having a few old phones and access to $10/month plans, it would be nice to just be able to access a phone from the world. It would be easy to monitor and perhaps control things at remote locations for cheap. I've used phones this way before, but they were alway on WiFi and so I had access. When they are the hot spot/AP, things get all jacked up. As an aside:I hate IoT.
If anyone has any thoughts, comments, or suggestions, I would welcome them.
If you read this far, I hope it was entertaining.
Final thought
After rereading this, I think I could just replace the Shelly with an X-10 light switch. Install the controller on the rPi and control it with a cron job. I could make any changes using the slow connection from the house. Or alternatively, I could use the native WiFi interface on the rPi as an Ad Hoc/AP for the Shelly. I did try this, but it didn't work. But I've upgraded the OS on the rPi to bookworm from stretch since then. Maybe that will address some of the issues.

tt seems like phones are locked down pretty tight. For example, it doesn't seem like you can vnc into the phone unless you are on the phones hot spot. Not only that, you can't use a remote ssh tunnel either, which kind of surprised me. I've take care to confirm that the firewall and SE Lonux settings would allow access to the required/specified ports.
Is this right? Is there a way around?
I have a location that doesn't have wifi on it's own and don't want to pay full rate just so I can occasionally access a little home automation.
