upgrading bitwarden / vaultwarden

I had posted earlier about running Vaultwarden (a Bitwarden server in Rust). This has been running amazingly all this time.

But today, when I tried to log in from the browser extension, I kept getting an error.

Searching in the forum, I found the issue – I had to update the Vaultwarden server.

Since I was running Vaultwarden as a Docker container, and I had run the docker command directly, so I decided to create a docker-compose.yml file instead this time.

Nginx – folders as subdomains

I have a projects folder in which I put multiple folders, each having an html page.

So, the folder hierarchy looks something like this –

projects
|-sampleproject1
  |-index.html
  |-style.css
|-sampleproject2
  |-index.html
  |-style.css

I want to have each of these folders as subdomains to my domain, so I had to create an nginx conf file for each one with a different root path.

I was looking for way to have this done automatically using Nginx and finally found it!

Postgres pg_dump without password

I have to do a dump of a Postgres database on a regular basis.

So pg_dump is the obvious choice to do this as is cron to do this periodically.

But the main problem with this is – pg_dump expects a password to be entered at the prompt. There’s no way to pass the password in the prompt to be able to do this.

Stackoverflow to the rescue.

What is required is a .pgpass file in the home directory.

‘asdf’ not finding program

I discovered asdf quite late! I was relying on a bunch of different programs to manage Ruby (rvm), Node (nvm).

asdf was an amazing headache saver. It already has core plugins for Elixir, Erlang, Node and Ruby. Plus, it has community plugins for what seems like practically anything under the sun.

I had installed asdf on a new system. And as usual, there were some crons to run on it. I kept getting a /bin/bash/ruby not found error.

After some time I realized I had faced this problem before as well!

Ruby Sequel migration – increment column in a group

The requirement was to add a column called position to the order_details table.

The order_details table is actually a table with a foreign key of order_id. The requirement is to increment the position starting from 1 in the position column grouped on order_id.

So, before the migration if the records are –

id  order_id
1   1
2   1
3   1
4   2
5   2
6   2

After the migration, the records should be –

id  order_id position
1   1       1
2   1       2
3   1       3
4   2       1
5   2       2
6   2       3

There are two solutions possible. One using window functions and one without.
