I am trying to host my first website + service.

#My server setup

I have a static webpage in server 1. A gotosocial installation in server 2. They are connected to a reverse proxy (server 3). This has a public IP of (not exact) 204.230.30.104.

#My router setup

I can open ports 80 and 443. I just don't know to which IP (I'll explain why down).

#My registrar

In have a domain, say 'newexample.com'. The @ has an A record for the IP (not exact) 208.145.80.33

#My confusion

1. If I want to make a subdomin for GoToSocial like 'gts.social.new example.com', do I use CNAME or A record?
2. If I want to serve the static website to be served at 'www.newexample.com' , do I remake an A record for www.newexample.com ?
3. There appears to be a CNAME in my DNS record already by the registrar for www that goes to some "redirect" link. What's up with that?
4. How do I make the domain connect to my server and how to make the server connect to my domain properly?

The academic meme community here is absolutely ace! But what I would also like is to communicate with other academics in my field and share the latest publication and talk about it a bit if possible with peers.

I used to use Twitter (back when it was called Twitter) to post about my new publications. Now I use Mastodon. Say what you wish about the negative aspect of algorithm based feeds, I am currently finding it hard to connect with other academics whose profiles may be dispersed in the wide fediverse.

Long story short: How do I disseminate my work and connect with other academic peers in my field on the fediverse?

I'm study biosystems and circular economy.

I have a headless RaspberryPi Zero W that I wish to use as a server for remote printing so my neighbours and myself can have a common printer. The printer unfortunately is an HP LaserJet 1020 - the one my neighbour has happily given to me. But setting it up as a remote printer has been a horrible experience for me.

I'll write down a few of the commands I have tried to get it to work.

First I made sure that the laptop is connected to the laptop with the command :

lsusb

When I could see the HP printer I proceeded with:

sudo apt install cups hplips printer-driver-foo2zjs printer-driver-foo2zjs-common printer-driver-foo2zjs

From my laptop browser, I went to <my.ipv4.address>:631 and added the HP printer. Selected the driver. Checked the Shared Printer option.

Now, I rebooted the pi, re connected the printer, and tried to print something via my Linux Mint laptop. no luck

Then, I read around and found that I need to run the command:

sudo hp-setup

So, I ssh'ed back into the pi and tried to run this command and the entire pi crashed.

Has anyone managed to get this darn machine working nicely?

We're all Linux users, so I don't need to install samba and all that.

I have made a website in simple HTML and CSS (no JS).

I hope it would be compatible with as many browsers as possible.

Is there a free and open source solution that can test and reveal the oldest version of each browser compatible with my site? I want to be able to say something like: This site is compatible with FF v60, Chromium v50, Safari vxx, etc.

Or make a compatibility table so users can know that this was tested.

I want to set up my own Nepenthes against LLMs. I have purchased a domain, say "wowsocool.com".

I have a RaspberryPi 4B that I want to use as an nginx reverse proxy, and an old Acer laptop that will host the Nepenthes. I am going to host this at my current residence router as I won't be staying there too long. I thought this was a cool temporary project.

My problem is that the website sort of glosses over the whole nginx setup and IP pointing etc.

If anyone has done this before, is it possible to please write up a dummy's guide that goes through everything. I am quite unconfident and my skills are nonexistent in this field.

Pretty please.

As I take on the role of a teacher, I am beginning to realise just how much of our documents aren't accessible. The university is pushing us to make everything accessible without a sensible pathway, but I'm going to try my best and make sure my students can access my documents without hindrance.

Currently I am trying to make my PDFs UA2 compatible using LaTeX. I also want to make sure my documents are colour blind friendly. A colour-blind simulator software would be great.

Is there like an "accessibility" suite one can self host to pass documents to check for various accessibility parameters?

Software to check PDF-UA compatibility?

My university is pushing for us to ensure that all our documents are accessibility-friendly. I write all my documents in LaTeX and have been taking the steps and measures to ensure that everything I generate is tagged, has alt text, and colour-blind-friendly.

Unfortunately, it seems the only way I can check for PDF-UA compatibility is with Acrobat Pro which the uni does not provide for us. What's more is that I use Linux and Acrobat doesn't work in that OS.

Is there a Linux-friendly libre software that can check if my PDF document is compatible with the machine-checkable requirements of Matterhorn Protocol?

The United States of America has become the biggest aggressor and oppressor on this planet. They went from being "upholders of democracy" just after WW2 to downright Nazi-land.

They haven't won a single war without the help of their European allies and yet have all these military bases around the world that help fund their disgusting military-industry complex and put on this pseudo narrative of being global peace-keepers when all they have done is kill innocent people, and raped women and children.

Their latest victim is going to be Nigeria and unless other countries band together to boycott and sanction the US, nothing will change.

I currently have a Phyhome P20 ONT setup. When I checked the list of supported devices for OpenWRT, I couldn't find it there.

Are there ONT style devices that are OpenWRT compatible?

I shifted homes and my new place comes with a connection that is ONT.

The router unit is a Phyhome P20 ONT. I don't have the option to assign static IP to devices, nor set another device as a DHCP server.

Is it possible to run a pihole effectively in such a setup? I honestly wanted to install OpenWRT, but I understand that it isn't possible with ONT style setups.

I am seeing a growing discussion on the need for more Linux phones in the market given Google's problematic behaviour w.r.t the changes that will be introduced to that OS.

One very good point that some community member raised was that Android itself wasn't the problem but the locking of the bootloader in the phone. If the bootloader could be unlocked, then it significantly lowers the bar for the end user to install their OS of choice.

I have dabbled with flashing OSs in old smartphones (GrapheneOS, Post market and Lineage). I commend the developers because I could do that without truly having to "understand the code" at the lower levels. But I assume that was possible because the boot loader could be unlocked somehow*. It seems that isn't the case with many/most phone fro. Samsung / Xiomi, etc.

Are their bootloaders truly unlockable? Is it simply impossible to unlock and relock bootloaders?

• I know that with lineage, the bootloader couldn't be relocked and that was touted as a security flaw. If someone could explain why this lock/unlock is so complex, I'd appreciate it.
