Hello, I have a rather complicated need to use a gre tunnel and I am having difficulty getting it working. The tunnel is between my home server and Oracle VM. Below is a picture of the topology with config.

Pings between the home server and Oracle VM over the gre tunnel do not seem to be going through as evidenced by tcpdump. I do notice however that the firewall has the correct state table showing that address translation. I am certain that both machines' firewalls are not dropping packets because iptables is not showing anything dropped. I am at a loss here so I welcome any ideas.

I'm struggling with CSS Flexbox. Each time I think I'm about to get it in an aha momet, I'm actually two steps backwards. I'm taking The Odin Project course and I'm at the phase where I am building the landing page. I've worked on it for 16 straight hours and I'm almost finished. It just looks like shit on a small screen but in fairness, the curriculum did mention that. Otherwise, what I have looks like the goal. I did one or two extra easy touches.

Okay so one question: when is it better to use flex-direction: column and when is it better to use flex-direction row? I'm seriously confused.

Hey! Does anybody have any information about if and when a company might offer ARM64 for general desktop use? I would like to build my own in the same way that I might build a desktop PC out of an Intel or AMD processor.

I am looking into getting started in web development and I came across The Odin Project. Unfortunately, I don't have the money to pay for a course right now. I currently work in a senior desktop support and systems admin role and I am seeking to pivot into web development. Is this realistic? What advice or websites would you recommend for me? Thank you very much in advance!

Hello fellow self-hosters. Is it possible to use NGINX as a proxy for an IMAP service where the IMAP server is located on a different host? I have a cloud VPS running NGINX which is connected to my home network via a WireGuard tunnel. What I would like to do is run the IMAP server (Dovecot) in my own network and have NGINX proxy the connection. I have tried doing searches based on this but the examples don't show how to specify the IMAP server for the connection to be redirected to for the lack of a better phrase. I know streaming is possible. Would this be the way to do?

I would love an example to go on. Thanks very much!

EDIT: With thanks to u/code@lemmy.mayes.io, I have a solution for cleaning up the one table that is growing ridiculously in size and that is the activity table. A TRUNCATE activity; command cleaned that right up. A word of caution is in order because the Lemmy instance must be shutdown completely and only the postgres container running if you're using docker.

As a new Lemmy admin, I think I really need to learn PostgreSQL administration because I need a way to keep my database from ballooning in size and there are no management tools built yet for it. Would someone be so kind as to recommend a good website for learning PostgreSQL? This would also help me maintain my mastodon instance.
