Running Local LLMs (“AI”) on Old AMD GPUs and Laptop iGPUs (Arch Linux Guide) A straightforward guide on how to compile llama.cpp with Vulkan support on Arch Linux (and Arch-based distros like CachyOS, EndeavourOS, etc). This lets you run models on old, officially unsupported AMD cards and Intel iGPUs.
The same steps work on Debian/Ubuntu, but the package names are different.
Here’s how I’m running models on 3 × AMD Radeon RX 580 8 GB (24 GB VRAM total) without ROCm in 2025.

I’ve made the source code to this website public!
If you’re curious about how it’s built, want to fork it, steal some ideas, or just poke around, you can find everything here:
👉 https://github.com/albinhenriksson/ahenriksson.com
It’s a simple Hugo site with a custom theme, a few tweaks, and no unnecessary fluff. Built with love, caffeine, and way too much time spent tweaking config.toml.
Enjoy, and feel free to open an issue or pull request if you find something broken (or want to add something weird).

The complete guide to installing Nextcloud on Debian 10 By Albin / 2020-02-24
Today we’re installing the free and open source cloud platform Nextcloud on a machine running Debian 10. Nextcloud is, in a nutshell, a secure self-hosted replacement for Dropbox, Google Docs and Google Calendar. You should own your data – not the big companies.
The guide somewhat resembles the WordPress how-to – as we did then we set up a database, a web server and a website written in PHP that is meant to sit behind a reverse proxy giving it a secure connection to the internet.

Fixing apt update/upgrade on Proxmox (without subscription) By Albin / 2020-02-24 – 2021-08-23
This is an extremely trivial guide – but when installing Proxmox for the first time I would have needed a guide like it.
As default, Proxmox is set to update against their paid enterprise repositories – but without a subscription you have no access to them. So what you have to do is remove the enterprise repository and add the free equivalent.

Set up a log server with Rsyslog on Debian 10 By Albin / 2020-01-30 – 2021-08-23
It is very handy to store all your logs in one place, especially in the event of a crash on one of your machines – you can then do the detective work on why it crashed using another computer (that works). It is of course also easier to search for errors across your machines and similar tasks.

How to Install TensorFlow with GPU Support for AMD on Debian Buster By Albin / 2020-01-28 — Updated 2021-08-23
The official TensorFlow only supports NVIDIA CUDA-enabled GPUs — which sucks for us AMD users. But there’s a workaround: we’ll use the open source ROCm project from AMD.
1. Add the ROCm Repository and Key wget -qO - http://repo.radeon.com/rocm/apt/debian/rocm.gpg.key | sudo apt-key add - echo 'deb [arch=amd64] http://repo.radeon.com/rocm/apt/debian/ xenial main' | sudo tee /etc/apt/sources.list.d/rocm.list sudo apt update 2.

How to enable uploads of files larger than 2MB to your WordPress-site (using NGINX) By Albin / 2020-01-28
I. Configure PHP-FPM We start by editing the PHP-FPM configuration file php.ini, found here on Debian Buster (replace 7.3 with whatever version you’re running):
nano /etc/php/7.3/fpm/php.ini Add the following lines at the very end of the file. (Check out what this actually does on https://www.php.net/manual/en/ini.core.php)
upload_max_filesize = 100M post_max_size = 100M Reload the PHP-FPM service:
systemctl reload php7.3-fpm II. Configure NGINX Now we configure the NGINX website configuration file on the host (note: not on the reverse proxy):

How to set up WordPress behind a secure reverse proxy using NGINX By Albin / 2020-01-27
After getting your SSL certificate and enabling HTTPS redirection in NGINX, WordPress will not work due to mixed content (HTTP and HTTPS) – you won’t be able to login.
To fix this:
1. Edit wp-config.php Add this at the very start of your wp-config.php:
define('FORCE_SSL_ADMIN', true); if ($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') $_SERVER['HTTPS']='on'; Then, at the end of the file, add the following (replacing website.com with your actual domain):

Make Debian/Ubuntu LXC containers more comfortable to use By Albin / 2020-01-26
I’ve been playing around with Proxmox and LXC containers lately and this is something I do with every container I create for it to be more user-friendly.
1. Enable colors in the terminal echo "PS1='\[\033[1;36m\]\u\[\033[1;31m\]@\[\033[1;32m\]\h:\[\033[1;35m\]\w\[\033[1;31m\]\$\[\033[0m\] '" >> ~/.bashrc 2. Enable tab completion echo "source /etc/profile.d/bash_completion.sh" >> ~/.bashrc 3. Fix locale problems echo "LC_ALL=en_US.UTF-8" >> /etc/environment echo "en_US.UTF-8 UTF-8" >> /etc/locale.gen echo "LANG=en_US.UTF-8" > /etc/locale.conf locale-gen en_US.UTF-8 4.
