Techniques and Web Technologies
After some time, I decided to build a lightweight UI for my local LLM experiments. The goal was simple: a single-file web interface that supports RAG (Retrieval-Augmented Generation) without the bloat of modern frameworks.
I’m putting my blog on a bit of a hiatus for now. Lately, my interests have shifted elsewhere, and I’ve found myself exploring new projects and passions outside the realm of WWW technologies and Linux. While I might still post from time to time, I’m not sure when or what exactly I’ll write about next – it’ll depend on where my curiosity takes me.
This post describes how to Install Node-RED to Fedora in few steps with dnf and npm install command. Node-RED is build on top of nodejs so only nodejs should be installed with root permissions. Other steps will install Node-RED in home directory as ordinary user.
X96Q is nice android TV box and it was supposed to breathe new life into old LG 42LD650 TV.

After xmr-stak is successfully compiled, with enabling huge pages Monero mining can be improved for around 20%. In this post will be shown how to set huge pages on Linux and how to set memlock too. And lastly, you will find Bash script for starting Monero miner.
This post describes how to compile xmr-stak Monero miner on Fedora 30 for older Nvidia graphic card. In my case Nvidia card is Quadro K2200 and compiling with gcc9 was not possible because gcc versions later than 8 are not supported. The solution was to build gcc7 with gcc9 and install to /usr/local directory where will not interfere with other packages.
As described in my earlier post, disabling pulseaudio and setting ALSA audio for Linux Kodi setup should be easy. Unfortunately, stopping pulseaudio from respawing was not possible until pulse audio daemon was uninstalled. Here is description of this simple solution.
The goal was to install Windows 10, Fedora 28 and Fedora 27 on a single PC with triple boot option in UEFI mode. Fedora 28 is installed as a workstation while Fedora 27 is configured in non-gui mode. During installation there were few fails and tricks ideal to write it down in this post.
During adding and removing kernels on my multi-boot PC, I ran into “Device or resource busy” error. The problem was in used device-mapper as leftover that was shown on dmsetup list. After removing device definitions (clearing list), I was able to recreate boot grub2 options.
This post describes Fedora 27 AMD driver installation and xmr-stak compile steps. In scenario without GUI, “worker” will be launched in runlevel3 and therefore only OpenCL is needed to install from AMD driver package.
My goal was to set minimal Kodi installation on top of Fedora 25 with bypassing desktop environment GNOME, LXDE or so on. USB automount is needed functionality for Kodi as standalone to be a complete media centre. This post describes how to set automount without any help from desktop environment.
