Recently this error showed up on my Kubuntu 23.10 while trying to run applications using QtQuick, such as QtDesignStudio or just a new QML project with QtCreator. The application either outright does not run or has serious GUI issues.
Turns out this is probably an issue related to software and distributions switching from Qt5 to Qt6.
Continue readingLua is a simple, fast and embeddable scripting language. Capability to run Lua scripts can be relatively easily added into C and C++ applications. Due to it’s ease of use and performance it’s being used in computer games (Crysis, Garry’s mod, …), general software (Wireshark, Neovim, …) and also embedded devices (Logic Machine). Let’s take a look how to create a very simple Lua console GUI with Qt.

When we talk about environment monitoring, temperature monitoring is one of the most ubiquitous use-cases and makes for an illustrative example as well. The measurement side of the process is not an area that would offer many exciting innovations in this day and age – today it is all about how you process the collected data.

If you want to take good care of your lithium-based battery, you should not charge or discharge it completely, but stick just to a part of the total range. This way you can increase the number of charge-discharge cycles it survives and thus prolong it’s life.
Certain laptops offer ways to set battery charging thresholds.
Have you ever been annoyed by terminal windows not aligning their edges with edges of other windows or screen edges in xfce? Seems like there is an easy fix, if you know where to look!
UPDATE 22.1.2018
Some parts of this angry rant still hold true, but Plasma desktop sure improved greatly since this post was originally written. I now run latest KDE software on Manjaro for several months and it sure got good enough for my day-to-day use. New post incoming… maybe when I get around to it.

First of all, I would like to state that I’m a fan of KDE. Some of their programs and utilities are unmatched by any other. For example file browser Dolphin, text editor Kate, the great PIM suite Kontact, … the list goes on. Also the level of customization is borderline fetishist. KDE desktop lets you do absolutely anything you ever thought possible and more… or it seems so at first. Then, in the moment of awe, the first crash comes. Then you start noticing weirg glitches and somehow missing features.
Thanks to Nvidia’s Linux4Tegra and work of Bogdacutu and Steel01, as of today I’m running desktop Ubuntu on my Shield Tablet. And it works surprisingly well. Except some tablet-specific hardware like the modem, accelerometers and such, of course.
All it takes is to install MultiROM, patch the kernel and install the appropriate Linux4Tegra installation archive next to existing Android system and there you go:
