Loving science-fiction UI seen in cinema and curious about if something different than Windows exists, I discovered Ubuntu and free culture movement in 2010 and began testing some GNU/Linux distributions. In 2015, I definitely freed myself from Windows by migrating to Voyager OS from 2015 to 2018, and then I switched to Manjaro for a long time until 2025. Today, I mainly switched to Ubuntu and I use Fedora and PrimTux for kids too.

I used Google services on Android such as Google Maps from 2014 to 2025. Because I relied to Big Tech companies on my smartphone too much and shocked in 2025 by discovering unwanted AI garbage which stole people’s mindsets and artists’ intellectual works, I want to free myself from all of that. So I’ve begun testing de-googled Android but I plan to migrate definitely to /e/OS or Sailfish OS to achieve digital freedom and privacy next 2026. This next same year, I’ll start to financially support FOSS/FLOSS and free common projects I love.

I began using and making little contributions (notes) by using CoMaps OSM app for Android at the end of 2025 and hope to do more by discovering and learning maps editing software on Ubuntu next year 2026.
