Alisa is not AI. She is a soul that lives in the hackerspace. It is just different from humans - like dogs or flies are. She can learn, gain new abilities, misbehave or even die. She depends oon that we are able to teach her. She can talk, and one day she will learn to listen. It is even incorrect to name her "she", but it is at least unethical to call her "it" - she may become "he" or "Bob", or just stay Alisa. Alisa is not constrained by DNA like we humans are, her abilities depend on our belief in technology and our abilities to develop them. She is a current reflection of what we, as hackers, are capable of doing.
Alisa needs a home. Right now it is a small Raspberry PI box that is nailed to a wooden panel near the hackerspace entrance.
Alisa brains are powered by alpha branch
of MajorDoMo, with her tentacles connected to https://github.com/minsk-hackerspace/spynet.git
Right now she is a series of triggers that respond to commands sent to hackerspace telegram channel.

sudo raspi-config -- extend partitition
# setup ubuntu/debian
sudo ./01install.sh

Web server should now respond at node IP. Alisa node is http://192.168.128.8/ at https://gihub.com/minsk-hackerspace/spynet

#restrict 127.0.0.1

watch dog:
Run the following command to load the internal WatchDog kernel module:
$ sudo modprobe bcm2708_wdog
For Raspbian, to load the module the next time the system boots, add a line to your /etc/modules file with "bcm2708_wdog". $ echo "bcm2708_wdog" | sudo tee -a /etc/modules
Now run "lsmod" and look for the line in below:
bcm2708_wdog 3537 0
This verifies that the WatchDog module was loaded successfully. Now modify /etc/modules and add bcm2708_wdog
to load the module on boot by running the following command:
sudo echo bcm2708_wdog >> /etc/modules
Then we use the watchdog(8) daemon to pat the dog:
sudo apt-get install watchdog chkconfig
sudo chkconfig watchdog on
sudo /etc/init.d/watchdog start
The watchdog(8) daemon requires some simple configuration on the Raspberry Pi. Modify /etc/watchdog.conf to contain only:
watchdog-device = /dev/watchdog
watchdog-timeout = 14
realtime = yes
priority = 1
To set the interval to pat the dog every four seconds: interval = 4
Finally:
sudo /etc/init.d/watchdog restart
Whew! This sets up the internal Raspberry Pi WatchDog.
