This post is dedicated to a list of software I am using (or tracking in case I need more functionality to process data). Nowadays there is so much software that it is difficult to choose anything for personal needs. So I decided to create this list to keep track of the programs that might be very helpful. By default, all programs are open source and freely available for Windows, Linux, and macOS. However, some are distributed under restrictions, which is indicated near the description. The ones that are dedicated to working with online resources (Brave, OnlyOffice) are also accessible for Android and iOS. LibreOffice and Firefox, available under Mozilla Public License 2.0, are well known, so there is no reason to give more description for them.
