R (rlang) and Plots everywhere

Data science and Jupyter notebook can sometimes get exhausting. What about debugging, version control, code reviewing and so on. Coming from a Software Engineering background it‘s like losing 50% of the stuff you were used to.

To mitigate those problems I recently partially switched from Python to R with many improvements. For local Python coding, JetBrains PyCharm is my tool of choice and Jupyter notebooks for remote coding. With R it is RStudio Desktop and for remote, there is RStudio Server, which is almost like the desktop version within a browser. This allows one to develop and analyze data from any device with a browser.

Corona COVID-19 meets QGIS – create your own maps

The Center for Systems Science and Engineering (CSSE) at Johns Hopkins University provides the famous Corona Dashboard and Map (ESRI ArcGIS Online App) and an ArcGIS Feature Service with the recent data (and a GIT Repo with the raw data). The ArcGIS Feature Server support of QGIS makes it easy to have „some fun“ with QGIS and the provided datasets.

Base Installation of Arch Linux + Good to Know

Install

If you want to install Arch, everyone tells you that you should read the installation guide. The second thing you may hear is that you should read the installation guide and that you have to follow it step by step. That also has a short name RTFM – Read The Fucking Manual – and stick to it – no joke.

Make backups before installing Arch Linux. 😉

Why Arch Linux?

My History

For four years now, I used Manjaro as my main GNU/Linux distribution for my daily use. That includes developing with Java/C++/Python and data analysis stuff with R/Python.

Now for me, it was time to switch from Manjaro to another distribution. Sidenote: Manjaro uses Arch Linux as base distribution but provides a considerable amount of additional services out
of the box. Manjaro was running fine for four years now with only one incident, with the integrated WWAN modem.

Since I started to use Manjaro, I fell in love with the „rolling release“ feature with an up-to-date kernel and all the up-to-date packages. I decided that it is time to switch to plain Arch Linux for me now.
