Alisa - MXC AI

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's Home

Alisa needs a home. 2016 it was a small Raspberry PI box nailed to a wooden panel near the hackerspace entrance.

~ Sweet ~

2024 is it the same small Raspberry PI box now on the top shelf of the cabinet nailed near the hackerspace entrance.

~ Sweet24 ~

~ Brainzzz

Alisa brains are powered by alpha branch of MajorDoMo, with her tentacles connected to https://github.com/minsk-hackerspace/spynet.git

~ Design

Right now she is a series of triggers that respond to commands sent to hackerspace telegram channel.

~ Setup

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

# setup majordomo (smart home platform)
./02checkout.sh

# configure PHP + Apache2
sudo ./05config.sh

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

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.
