Is there a way to dual-boot a Raspberry Pi 4, not with a set of partitions, but with multiple SD cards? I would like to have a couple of SD cards in my Canakit Raspberry Pi, with the ability to boot from a different SD card on boot. My idea is to have 1 or more productive setups (Raspberry Pi OS) and 1 gaming setup (RetroPie) without having to unplug the SD cards each time. #raspberrypi #rpi #rpi4 #dualboot #hardware
Bojoval jsem s #Remmina při připojování k #VNC v novějších verzích Raspberry Pi OS (např. Bookworm) který teď používá výchozí šifrování, které Remmina nepodporuje. Původně jsem chtěl editovat VNC server na #RPi, ale nakonec jsem usoudil, že je to nesmysl a prostě jen nainstaloval #RealVNC do #Fedora a ten to vyřešil. Nevíte někdo jak to bude s Remminou dále? Bude aktualizována, nebo už ne?
I was tired of counting pins when working with electronics like the Raspberry or ESP32, so I created a simple editor that generates pinout diagrams that fit right onto the board's pins.

@raymierussell first go for an SSD, it will help in speeding the machine.

I had a Celeron 1000M machine, wasn't that bad under Gnome but it had 8GB ram. Maybe XFCE it's lighter, or the DE of #rpi that uses wayland, is wayfire its name?

I use to compose my distro () so i'm not in the position of suggesting you a particolar distro, outside of a Debian or a Mint, outdated software problem can be solved by using flatpaks from Flathub.

Thinking about having a special #WalpurgisNight streaming of my #Minecraft world for my followers! But I suck at Minecraft, never streamed, don't know how to stream from #RPi, I've only played like 15 minutes in my current world. But surprisingly, I can play Minecraft from a #RasburryPi 5. And I have no followers in any streaming services.

But give me a #boost if you want me to!

@cldferrilab spero siano MB/s perché in megabit vanno più veloci le microSD che si mangia il mio #rpi

I recently changed to a fritz box router and pinole has decided not to work anymore...

Anyone got any ideas? I can access the web interface but DND doesn't work from at least some of my devices...

I'll probs be changing my pis which host all my services to use k3s soon so will probs reinstall OS then, in case that makes any difference.

The new router did change my gateway btw, I think all the devices use the correct one now though.

Fin whale song recordings by onshore seismometers open new horizons for cetacean coastal monitoring - Scientific Reports

Fin whales, the second largest animal on Earth, produce one of the most intense vocalisations in the animal kingdom. Monitoring these songs using ocean-deployed hydrophones plays an important role in the study of fin whale distribution and social behaviour, though obtaining real-time data remains challenging. In this feasibility study we investigate if vocalising near-coastal fin whales can be widely detected and located with onshore seismometers. Inspecting data from pre-existing seismic installations we establish that fin whale song can be detected with onshore seismometers up to 5.5 km inland, across multiple marine environments, globally. Individual creatures can be located and tracked through the analysis of seismic wave properties. Furthermore, we show that citizen science seismometers, such as the affordable and widely deployed ‘Raspberry Shake’ devices, can reliably detect fin whale song. These instruments, often placed in coastal areas, provide real-time data, offering a cost-effective and accessible method for monitoring coastal fin whale activity. The revelation that human living spaces are ensonified by fin whale song offers the potential to enhance public engagement with the oceans and presents new opportunities for global monitoring. Fin whales are vulnerable to noise pollution, shipping strikes and entanglement in fishing gear. The use of terrestrial seismometers could improve early warning systems and contribute to richer datasets on near coastal whale vocalisations. This study demonstrates that, globally, seismic data holds significant untapped potential for near-coastal fin whale monitoring.
