Raspberry Pi 3B+ eth0 stays up after pulling cable

When I remove the Ethernet cable from my Raspberry Pi 3B+ and do ifconfig I see eth0 stays "up" and IP is still configured. When then connecting to wlan0 internet is not working because all traffic is still routed through eth0 (which is not connected anymore) instead of wlan0. Tried to manually shut...

Hi, I've been playing around with the hello_fft.c GPU accelerated FFT example but I have some questions about the results. For example a sine wave of 20Hz in 1024 samples as input signal: input.png This gives the following result: a peak of 511 at sample 40. I'd rather expect 2 peaks of 1.0 at 492 a...
