If you see that on a new SD card, I would suspect broken hardware. I've never seen that error before!

thank you Jamesh,
Do you know the most likely door they used to enter ?
the web server of domoticz ?
openvpn ?
I had already changed the passwords of root and pi. Can I find a trace in a log system of their entry into my system ?

I have no idea. Sorry.

Re: Pi 3 B+, v2.1 camera abyssmal fps @1080p

I was quite surprised by the cause as well, I can't make the connection. The only thing I though of is that both of them are going through the GPU somehow, which causes more strain on the GPU when trying to record and output 1080p as well, but that seems unlikely. The GPU can easily handle 1080p30 ...

Re: ScriptBasic

The big unknown is whether /dev/gpiomem will continue to exist in the future, whether direct memory access will be disallowed, and everything has to be done through libgpiod. I am still in the early stages of investigating libgpiod because it will no doubt have implications with GPIO use and partic...

Re: raspiraw different output after raspberry update

Good guess, it was indeed the firmware. I did a rpi-update and launched the function and the output was 407 kB. It's still incomprehensible for me, why does something unchanged won't work after an amount of time while the same thing was working before. Thank you very much anyway. Software is softwa...

Re: Pi 3 B+, v2.1 camera abyssmal fps @1080p

I have been experimenting as well, trying to figure out the bottleneck and it seems to be the HDMI signal output, When the pi is outputting 1080p HDMI signal, the camera performance is seriously degraded (almost 50%), it shows up as 30% lost frames, but actually the only way to get a stable video i...

Ubuntu also (used to?) use the infinality font tweak package that could get fonts looking better than Mac OS: lots of subpixel rendering and correcting for LCD pixel colours. It may be standard everywhere now.
Very CPU intensive though. I'll check with Simon to see how we deal wtih this stuff.

Re: Kernel update uses 10 more process threads?

This is a complete guess. All I know is that my system generally uses 90-92 threads after booting (as per the 'top' command). Now it uses 102. It could easily be something else. Here is a list of those threads on boot: $ ps -A PID TTY TIME CMD 1 ? 00:00:01 systemd 2 ? 00:00:00 kthreadd 3 ? 00:00:00...
