dug VS pg-mem

Just joined the sub after coming across it dozens of times while learning things to help my homelab. My first post is a shameless plug for a CLI tool I made that quickly helps users get an idea of how much their DNS has propagated. I use it all the time for my self hosted stuff (recently when i was playing with external-dns) and wanted to share to see if it can help anyone else. https://dug.unfrl.com https://github.com/unfrl/dug

For people who want to understand, learn about, or stay on top of their, DNS check out dug. Its a cli tool I made to help visualize DNS propagation but is a great learning tool.

Good article, totally correct that that is how to definitely 100% get the correct answer.

The bottom of the article, with 'other ways' got me thinking that another way to get what is very probably the correct answer is asking a bunch of other DNS servers what they think the correct answer is.

Using dug (https://github.com/unfrl/dug) like: dug -q NS jvns.ca

Gotta post this every time theres a big DNS issue, which seems daily now.

Check out Dug! Its a global DNS propagation/monitoring toolon the CLI: https://github.com/unfrl/dug/

This release is primarily focused on the 'Watch' feature (-w, --watch) which allows users to monitor their DNS propagation in realtime.

I've used pgmem https://github.com/oguimbal/pg-mem for the last couple of years for the same thing.

I was wondering the other day how to classify tests that use a test double like pg-mem, which isn't a mock but isn't the Dockerized test DB either :

In my case, I use TypeORM with PostgreSQL, and there's pg-mem to run an instance in memory, it supports most of the common functionality of PostgreSQL but you will need to do some adjustment to your code to be within the limits.

Postgres in the browser is possible through pg-mem: "pg-mem is an experimental in-memory emulation of a postgres database" but it also suffers from no persistence. If you can persist to a file somewhere then read it in on startup (and if your local data isn't huge) this might work.

Dont get me wrong: I am trying to contribute to opensource as well, so I get that supporting small projects can be demanding. There's nothing wrong in not spending your weekends on OS. But not asking for help, nor specifying that a project is unmaintained, nor even answering issues & pull requests for years feels just wrong.

Okay, I had a bit of spare time,I've implemented that, and it is now available with [email protected]

To get a glimpse of what I'm talking about, you can clone this repo and follow "Development" instructions (by the way this is a small OS lib I maintain, I wrote about it here)
