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.

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.

2024-03-01 listening in on the neighborhood
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:

DietPi released a new version 9.1
DietPi is a lightweight Debian based Linux distribution for SBCs and server systems, with the option to install desktop environments, too. It ships as minimal image but allows to install complete and ready-to-use software stacks with a set of console based shell dialogs and scripts.
The source code is hosted on GitHub: https://github.com/MichaIng/DietPi

The Orange Pi 5
Before someone starts the usual yadda yadda about the RPi biger community, the OS not having long time support etc. I would repeat one more time: do not rely on board vendor supplied images; this is valid for pretty much all boards. Just go to Armbian or DietPi pages and you'll almost certainly find one or more images that work on your board and forums to discuss about them with very knowledgeable people.
https://www.armbian.com/download/
https://dietpi.com/#download
Those projects are well worth a contribution, as they don't have a giant like Broadcom behind them.

OpenWrt One/AP-24.XY: new open source router board by OpenWrt and Banana Pi
> bananapi do a lot of boards but their software story has been a bit poor
This is quite common with other board manufacturers too. I'd rather suggest to ignore completely their cobbled together distros, often also tainted by proprietary modifications, that become unmaintained in a few years, and see if they're among the many supported by Armbian or DietPi.

Looking for a way to remote in to K's of raspberry pi's...
RPi OS = diet pi https://dietpi.com/ - initial config via text file - SDcard burning out partially mitigated as writes log files to ram then flushes to SDcard reducing write cycles

Laptop so slow that even XFCE is laggy. What distro could run better?
You could also try very minimalistic distros like TwisterUI or DietPi which are most known for their use in the RasprebbyPi / SBC computers but which also have editions for desktop / laptop.
What are some alternatives?
