I use Ubuntu (20.04 LTS, now 22.04 LTS) as my main operating system. Some background on switching from OS X to Ubuntu here: https://github.com/bjohas/Ubuntu-keyboard-map-like-OS-X. I don't really use Windows at all, and I am surprised with how the intial setup of Windows has gone wrong for some of my friends (missing dlls, etc etc). However, there are a few 'OS X / Windows only things' and with a larger SSD on a new laptop, I thought I'd preserve Windows. E.g., 'OS X / Windows only things' include Adobe Creative Suite, as well as using Oculus/Meta Quest 2 via a PC connection.

Dual booting Ubuntu and Windows with encryption (for Ubuntu 22.04 LTS)

I used these instructions to dual-boot-ubuntu-and-windows-with-encryption.md https://www.mikekasberg.com/blog/2020/04/08/dual-boot-ubuntu-and-windows-with-encryption.html

Dual-booting with encrypted storage should not be this hard in 2020 2022.

Switching from XML to xml2

Rationale

The R package XML for parsing and manipulation of XML documents in R is not actively maintained anymore, but used by many:

The R package xml2 is an actively maintained, more recent alternative.

This file documents useful resources and steps for moving from XML to xml2.

Quickstart Guide to undertsanding the Qualtrics Survey File

This information is likely to quickly become outdated when Qualtrics next changes the formatting of the QSF file. This guide was started February 2017. I hope that it is a useful introduction to understanding the contents of the QSF file that one can download from Qualtrics.

This document includes:

• An introduction to JSON
• The Anatomy of a Qualtrics Survey File (QSF)
• A Breakdown of Question Structure
• A Guide to Recognizing Question Types
