Oh I’ve been at this for a while now. I tried that exact page you have suggested along with the information provided here: wundertech.net/how-to-set-up-pi-hole-and-unbound-…
The docker container is simply not composing and running into other errors that don’t make sense despite reading up about them.
I’m not a computer whiz, so any insight would be super helpful
Help with installing PiHole on PostmarketOS
I am trying to get pihole with unbound installed on a PostmarketOS device (open rc init). I can’t seem to get this installed at all. I tried using the bash installer, but that didn’t work. I tried using the Alpine repositories, but it didn’t work either. Anyone with tips or resources on how to get this thing to work?
What's up with expired domains being unavailable?
A domain name I was interested in expired in January this year. It was previously registered at Squarespace.com [http://Squarespace.com]. Why is it still unavailable to purchase despite being more than a month since its expiry? Not sure if relevant but I checked the expiry date at: whatsmydns.net/domain-expiration [http://whatsmydns.net/domain-expiration]
Help making sense of IPs and A records
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 [http://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 [http://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 [http://www.newexample.com]’ , do I remake an A record for www.newexample.com [http://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. 4. How do I make the domain connect to my server and how to make the server connect to my domain properly?
(Serious) networking with other academics appears difficult
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.
Requesting help to use HP Laserjet 1020 as a remote printer
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.
Is there a browser compatibility checker for websites?
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.
A dummy's request for Nepenthes
I want to set up my own Nepenthes against LLMs. I have purchased a domain, say “wowsocool.com [http://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 [https://zadzmo.org/code/nepenthes/] 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.
An accessibility testing suite
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 pishing 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?
Please suggest a linux-friendly PDF-UA checking software.
