Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Considerations for a long-running Raspberry Pi
This covers the readonly filesystem, but doesn't cover the write protect flag that you can set on the microSD card itself[1]. The flag will configure the card's controller to drop any writes.
Also, creating a readonly root out of an existing disto is a bit of a pain, my preference is to use a distro (like TinyCore) that's already a readonly root.

How to format SD Card that won't format or allow adding new data
If you have a memory card reader (not a USB based reader), you can inspect and unlock the SD card using SDtools - https://github.com/BertoldVdb/sdtool. Then try partitioning/reformatting the drive as you desire.

Write protected sd card problems
Bertold Sdtool can be used to change and query the write status, but as stated, it doesnt work for some reason

SD card "Write protected" after removing it from Raspberry Pi 4.
There's https://github.com/BertoldVdb/sdtool. Although unlikely, maybe you can unlock the card with it.

Going in circles without a real-time clock
Unfortunately a Raspberry Pi is a bit ill suited for production environments. Id recommend an RTC module. Otherwise this might be helpful: https://github.com/hcfman/sbts-aru

Running a Raspberry Pi with a read-only root filesystem
If you install my sbts-aru project
https://github.com/hcfman/sbts-aru
It will shrink your partitions, add news and install one of these and set up a sub micro second system clock and an audio recorder suitable for sound localization with a single install command.

I recommend primo EM272 microphone capsules for use with https://github.com/hcfman/sbts-aru. They are high quality, very sensitive with high signal to noise ratio, lauded for nature recording use cases. They can be bought assembled for around 65 euros in the Netherlands. However these capsules are often found in much more expensive equipment.

Considerations for a long-running Raspberry Pi
My sound localizing Raspberry Pi installs a resilient base system as part of its install.

With one command it for all Pi’s for both Raspbian and bookworm it:
* Shrinks the file system (Gee, how does it do that with just one disk ? ;-) )

Colorado wolf reintroduction to move forward as ranchers' legal effort fails
I have a sound localization project that can help with that
https://github.com/hcfman/sbts-aru
You need to be able to hear the sound from three or more recorders. And normally localization is better within the polygon of microphones but there’s an area of better localizability extending outside of a vertex.

Acoustic Location and Sound Mirrors
Interesting history!
And while we are in the subject of sound localizing may I take the liberty of introducing my new raspberry pi sound localizing audio recorder.
https://github.com/hcfman/sbts-aru
It installs with one command on all Raspberry Pi versions and synchronizes the system time to less than 1 microsecond of error with a cheap GPS.
With three of these I’ve been able to sound localize the explosions from illegal fireworks to a specific car park from more than 3km away with lots of houses in between.
When I got to the car park I could smell the sulphur from the fireworks.
This will even run on a Raspberry Pi zero running of a battery with a 6 euro neo 7m gps and a 6 euro usb mic.

AI tool helps ecologists monitor rare birds through their songs
Very nice tool!
So grab a spare Raspberry Pi, a GPS, a cheap USB sound card and a mic and get recording with this Pi based Acoustic Recording Unit
https://github.com/hcfman/sbts-aru
And while you are at it, install 3x or more and localize where the birds are.

Ask HN: Comment here about whatever you're passionate about at the moment
Sound localizing. I was intensely passionate about it when I saw the possibility to do it well on a Raspberry Pi. There were quite a few more problems than so expected which is why it took five months (of weekends) to complete it well.
But I’m super happy with the result and have a bunch of geeks with recording nodes setup a long distance apart. Localizing large explosions show that it’s possible to localize to a carpets even when some of the nodes are almost 5 away.
For those interested, here is the project:
