RushWorx Labs

I have an old mac mini that I want to back up, and of course I want to use Apple’s fancy Time Machine backup. Thing is, it’s old, from early 2009 and the newest OS X it can run is 10.11.6 El Capitan. Apparently, older versions of OS X can’t backup to Samba, which is what I use for serving files.

netatalk

Newer OS X can actually backup using Samba for Time Machine but older ones can only use Apple File Protocol (AFP). There is a project to run a AFP daemon on linux: http://netatalk.sourceforge.net/

In Debian 10 you can do the typical apt install netatalk, systemctl enable –now netatalk.

Config file: /etc/netatalk/afp.conf

;
; Netatalk 3.x configuration file
;

[Global]
mimic model = TimeCapsule
zeroconf name = fileserverafp
log file = /var/log/netatalk
log level = default:debug

[FS Backup]
mimic model = TimeCapsule
path = /storage/bu/timemachinebackup
time machine = yes
force user = rushworx
force group = rushworx
guest account = rushworx
valid users = rushworx

Surely I do not need all of this stuff but it works, and I don't use it for anything else so why fiddle with it. 

time machine

The missing piece of this puzzle is Bonjour / Avahi. I had issues with it but it turns out if you don’t have it all you have to do is mount the share once first, then it becomes available under Time Machine settings.

The shell itself suffers from rotted floors and suspension pickup points, hence the part out.

available parts:

Body panels are straight, without rust aside from very light surface rust, and in various states of rattle can black. Would be great for a race car or budget build. Not recommended for anything fancy as they would require a fair amount of prep.

• hatch with hinges and latch
• Fiberglass hood, has ~1” crack that needs to be patched.
• both fenders
• four-eye nose / bumper
• rear bumper
• rear quarter sections
• front and rear seats

parts not available:

• motor
• trans
• k frame
• rear end
• Doors
• dash and fuse panel
• anything attached to the above.
• anything not specifically mentioned in list of available parts

I have a computer in my living room PulseAudio. As is typical with Poettering software, PulseAudio is very unpredictable.

Within the Ubuntu settings editor, there is no way to permanently choose an audio device. Every time I reboot this computer, and sometimes when suspending, it reverts from HDMI to Analog. Within pavucontrol, you can set the default device but it doesn’t stick anyway. I suppose this has to do with the timing of HDMI audio device being detected as plugged in or some such malfunctioning automagic bullshit.

It’s highly annoying to change the audio device all the time, so here is how I got around this issue.

Disable PulseAudio

Strictly speaking, it is not disabled. Not in the sense of turning if off with systemctl, this just stops the binary from running, apparently:

mr@tvpc:~$ systemctl --user status pulseaudio
● pulseaudio.service - Sound Service
   Loaded: loaded (/usr/lib/systemd/user/pulseaudio.service; di
   Active: inactive (dead)
mr@tvpc:~$ systemctl --user status pulseaudio.socket
● pulseaudio.socket - Sound System
   Loaded: loaded (/usr/lib/systemd/user/pulseaudio.socket; dis
   Active: inactive (dead)
   Listen: /run/user/1000/pulse/native (Stream)

Like any software of this uh .. caliber, I have never found any official documentation particularly useful. However the Kodi documentation came in handy https://kodi.wiki/view/PulseAudio/HOW-TO:Disable_PulseAudio_and_use_ALSA(without_removing_PulseAudio)_for_Ubuntu

The relevant bit, in /etc/pulse/client.conf :

autospawn = no

ALSA Default Device

mr@tvpc:~$ aplay -l 
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC662 rev1 Analog [ALC662 rev1 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 7: HDMI 1 [HDMI 1]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The device I’ll be using is Card 0, Device 3. So, in /etc/asound.conf:

pcm.!default {
        type hw
        card 0
        device 3
}

ctl.!default {
        type hw
        card 0
        device 3
}

After a reboot, no audio devices show up in the Ubuntu Settings app.

Firefox

I like Firefox. Sadly, guess what? Apparently the Linux version of Firefox requires PulseAudio and cannot use Alsa as of many versions ago. https://support.mozilla.org/en-US/questions/1199433

So, I guess it’s time to change browsers. Chromium seems to work fine with Alsa without any fuss, so there you go.
