Re: Jessie: hosts.deny/allow does not work? [solved]

Why are you trying to use something that's been deprecated for ten years or more? Use iptables, it's more sane, has better granularity and is therefore more secure. If iptables scares the hell out of you then look at something like ufw (user-friendly firewall) to help build your iptables rules. I w...

Kivy touch examples?

On the Pi blog there were some nice Kivy touch examples using the new official Pi touch screen.
I have managed to get Kivy going, but touch does not work yet.

Are the examples shown on the blog posted somewhere?

Re: Pi causing network disruption for other devices !?

It certainly sounds as if the Pi is flooding the network with traffic. I find it mildly astounding though that it can flood a gigabit switch when connecting at 100M. It may be instructive to put the 10M hub back in and connect another port of it to a PC running Wireshark . Unfortunately a switch wo...

Maybe you can check if you still have a persistent-net rule in /etc/udev/rules.d? If so, just remove it for both Pi's.

Re: How to get high quality audio from R-Pi?

@Narf03:

Playing a 320k MP3 file is not a problem. The Pi can even handle 192000bps FLACs without problem. The sound cutting out is due to USB and/or SD card drivers issues.

Re: raspberry mpd and flac

The raspberry pi does not have any problems decoding FLAC files, even highres ones. You could however experience some crackles when using MPD with a USB audio device. With the latest kernel (#278) this is greatly improved but the pi kernel/firmware needs a bit more work to get all the kinks out.

If I set both of the parameters I get I/O errors.

I still have to use...

@bryankemp I can confirm that stressing the CPU (by executing: time echo "scale=5000; 4*a(1)" | bc -l -q which pegs the cpu for ~ 85%) the sound quality stays constant for normal mp3s.

I was happily playing music with mpd when, while doing a rpi-update simultaniously, made the pi do a kernel dump. Luckily it recovered and finished the firmware/kernel update.

I have attached the crash dump.
