Review: UBports on the PinePhone

At the end of 2021 I posted a review about the PinePhone and what it was like running the device's default operating system: Manjaro Linux featuring the Plasma Mobile interface. While I've had decent experiences with Plasma Mobile in the past, the combination of Manjaro, the PinePhone, and this interface left a lot to be desired. It was slow, it was unstable, and there were issues with the battery charge indicator. To make matters worse, the default applications were not polished or well named. It was a rough experience and, though I can see where there is hope for Manjaro on the PinePhone, I was eager to try something different. In the past I have had mostly good experiences with the UBports distribution. UBports is a community project which has continued Canonical's Ubuntu Touch operating system for smart phones and tablets. Since I've run UBports on devices which didn't have any more memory or processing power than the PinePhone, I was optimistic about trying out the PinePhone with this alternative distribution.

  • How to Enable MySQL/MariaDB Query Logging

    In this short and easy to follow guide, we cover how to enable MySQL/MariaDB query logging and save queries to a file. When using a database, it often happens that developers want to know what’s going on behind the scene. Whether it is for troubleshooting, performance tuning, or out of sheer curiosity.

After logging is enabled, the database server will write information to the log file when clients connect or disconnect, and it will log each SQL statement.

  • How to install Zotero on Ubuntu 22.04 or 20.04 LTS - Linux Shout

    Zotero is a reference management system and academic network, here we learn the steps to install Zotero in Linux such as Ubuntu 22.04 Jammy JellyFish or Ubuntu 20.04 Focal Fossa. Zotero is an open-source and free tool that helps in collecting, organizing, citing, and sharing research. It consists of two components: Zotero standalone (Mac, Windows, Linux) with a plugin for Firefox, Google Chrome, and Safari; Zotero web application: computer-independent access to your library, finding and setting up groups on specific topics (see collaboration), making contacts with others. The two components of this tool can be synchronized with each other.

With Zotero, you keep all information together and create a clear library for your project without much effort. It is particularly suitable for literature research on the Internet and the direct transfer of the researched data and works in groups that want to manage literature together.

Keyboards and Open-Source - Ignorance is bliss..

.

In my Keyboard Fun post from last year I talked a bit about my interest in mechanical keyboards. Since then, I played around with a few more keyboards/switches/keycaps/… Interesting enough, beside the actual hardware, naturally there is some software component to all these keyboards, too. Whereas most commercial keyboards still come with proprietary firmware, there is the trend within the keyboard enthusiast scene to go for open-source firmware. This allows you to properly update the firmware even from your Linux machine and do proper configuration of e.g. the keymap, too. Read more
