MOTA (Many of the Above) or Honest Voting - an application of approval voting in India.
View MOTA - Honest Voting.md

MOTA (Many of the Above) is Honest voting - you dont have to fear about vote wasting

This is very easy to describe to voters: vote for everyone you approve of.
MOTA does one thing very well - it removes any reason to vote against your favorite candidate.

Intuitive Explanation

In any voting system, if there's only ONE candidate - not voting and voting for the candidate are the same.
For TWO candidates - it is better to pick the one you like more.

View installing moby-engine+docker on Fedora 34
1. If ur upgrading from an older fedora,
1.1 `sudo dnf remove docker-*`
1.2 `sudo dnf config-manager --disable docker-*`
1.2 please ensure `/etc/default/grub` doesnt contain `systemd.unified_cgroup_hierarchy=0`. If it does contain, then remove it and run `sudo grub2-mkconfig -o /boot/grub2/grub.cfg`
2. reboot
3. set firewall correctly using `sudo firewall-cmd --zone=docker --change-interface=docker0`
4. in `/etc/sysconfig/docker` please ensure `--live-restore` is removed

fastapi with python 3.10 dataclasses - used to create both sqlalchemy and pydantic models simultaneously. And setting up sqlalchemy the right way (without deadlocks or other problems). Additionally, this also takes care of unified logging when running under gunicorn..as well as being able to run in restartable mode.

running postgresql on your laptop without installing it (using docker) . with connections to python
View pg-docker.md

docker network create pg

docker run -it --rm -P -p 5432:5432 --name pg -e POSTGRES_PASSWORD=password -e POSTGRES_USER=postgres -e POSTGRES_DB=production -v pgdata:/var/lib/postgresql/data --network=pg postgres

pgdata is the name of the docker volume. You can check it using docker volume ls and docker volume inspect pgdata. You can delete the docker volume by docker volume rm pgdata and prune all volumes using docker volume prune docker volumes are created in your central docker directory (usually /var/lib/docker/overlay2 ). You generally dont need to care about this.

You can now access it in many ways:
