Really pleased with the new Pop!_OS for Raspberry Pi. I've been using the OS on my personal laptop for years, but have been suffering with Raspbian on my Pi 400 for a while. This is a great, modern upgrade and is much easier to get interesting ham radio stuff compiled on. #hamradio #raspberrypi #popos #sdrangel #js8call
Experimenting with JS8Call on my Raspberry Pi 400 and FT991a. Unfortunately, my antenna (a V2000A) can't go very far in to the 6m range and doesn't reach the shortest "official" frequency for the protocol. But I'm hanging out at 52.535MHz in CN84 if there's anyone out there in range. #hamradio #js8 #data
...and the "read-only" file system bit is a red herring. It just seems to be trying to write to a nested folder that doesn't exist (like maybe 000/148/247/234/123 in this case) and giving up when it doesn't find the folder it expects.
Question for other Mastodon admins: I migrated my system to a new VM and now sidekiq is having trouble saving media files. It appears that it's trying to save files to the cache folders but isn't bothering to try to create the directory structure to accommodate it:
WARN: Errno::EROFS: Read-only file system @ dir_s_mkdir - /mnt/live/public/system/cache/preview_cards/images/000/148/247
I have to create the folders manually to resolve the error. Has anyone experienced this?

If you get a new audio interface like this one, check that your sample rate is correct before bugging your other synth manufacturer about their device being out of tune.
I always assumed a mismatch (48k when it should be 44.1k) would just result in distortion. Apparently it can sound perfectly fine - just out of tune. TIL.
Looking over the FediBlock list. It's troubling how "free speech" (or the non-cute euphemism "freeze peach") is used as the sole justification for a block in many instances.
I'll block an instance in an instant for being hateful or for harassment or for posting terrible stuff. But I'm not going to block someone for saying they support freedom.
Fiber is the superior medium for carrying fixed broadband by almost every metric: available bandwidth, SNR, theoretical capacity, real-world throughput, latency, and jitter.

...then to make it work, I configured one of the SRX interfaces with an address of 192.168.100.10/24 and added that interface to my starlink-untrust zone and my starlink-router virtual router. That was sufficient such that the app on my phone connected to my existing WAP (which routes through Starlink using the other SRX interface) can connect.
Starlink uses some unconventional configuration between their WAP, the dish, and the app to monitor the satellite connections. That monitoring communication is fixed to address 192.168.100.1, which Starlink expects to exist on the same L2 network as their CG-NAT range (i.e., not routed - same broadcast domain). I had to pull out an old Ethernet switch to make it work with my SRX 550. I used two interfaces on the SRX (one for each network) and brought them together on the little dumb switch.
The progression of my attempts to print a stand for my Jetson Nano with camera.
This is my second creation - other than printing a few predesigned models from Thingiverse just to figure out the mechanics of the printer. It's my first attempt at printing something designed in Blender to be measurement-precise.
I'll probably do one more attempt because the quality at the base of the legs is sloppy because of the near-horizontal orientation. I haven't quite figured out how to do that right.
