There are two kinds of literacy which every kid should acquire in school:

  1. Financial Litercacy
  2. Programming Literacy

While little is done about financial literacy even in the developed world besides some private initivatives (like my friend Mara’s books for children here or here), programming has gained more prominence in Europe’s schooling schedules for whatever reason. Naturally, as a parent you want to take every opportunity to support interest in creative digitalism.

My daughter is using the online LateX editor Overleaf to write academic papers and I’m always baffled how so called digital natives can waste hours and days formatting their…

The hype around ESG investing is strong and asset managers are vamping up their product-shelfes with ESG-labeled products. Academic papers to underline the fact that Large providers will happily sell you ESG scores to build your own portfolios. Unfortunately, the quality of the scores is not very uniform as of today. Managers with a mission will therefore fall back to reading annual reports of all issuers in their investment universe themselfes — which may be a lenghty and time consuming exercise.

When Falcon 9 launched yesterday and carried the Crew Dragon with Bob Behnken and Doug Hurley on board to Space, over 10 Million people were watching live through webstreams. That is an impressive number in itself. But compared to the moon landing in 1969 with estimated 600 Million viewers you could say that nobody really cared in comparison. Even more so if you factor in the availability of information of streaming vs. TV.

However, this success was politically important to the United States in times of turmoil. …

Sustainability is a dominant topic. The philosophical logic behind it is quite simple: Pollution leads to rising temperatures which will have adverse effects on humanity. Many — if not all — areas of life take advantage of the fact that public resources can be used for free, a problem know as tragedy of the commons.
