How to Pivertise your Pi

You know how sometimes you connect your Raspberry Pi to a wifi network and then you have absolutely no way of finding out its IP address (Zeroes are particularly bad for this)? Well, I fixed it. Paste the run-once-at-boot-time systemd script into /etc/systemd/system/pivertiser.service and enable it with sudo systemctl enable pivertiser.service, paste the terrible bash hack into /home/pi/pivertiser.sh and chmod +x /home/pi/pivertiser.sh, then reboot your pi and it should show its face over here

Those addresses are stored in a hash keyed on hostname, so clearly if you never rename your pi from raspberrypi then this is an astonishingly terrible solution, but it's just solved a little problem for me. And you can of course run your own instance on Heroku if you want to

vagrant up

  (select to bridge to eth0 or eth1)

vagrant ssh
multichaind odi-chain@10.14.3.49:9255

  It will complain, but it will give you a wallet address. Send that to me, and I can allow you in. Then
