Notes from a data witch - Unpacking Arrow Datasets
A comment on how Datasets work in Apache Arrow. I’m not really sure who the audience for this one. Am I just talking to myself? Probably.

In the words of Max Karson "16 year olds are retards"
Why don't we just give them basic human respect?
Let's stop treating teens like shit.

‘It’s Life or Death’: The Mental Health Crisis Among U.S. Teens
Depression, self-harm and suicide are rising among American adolescents. For one 13-year-old, the despair was almost too much to take.

When Leibniz algebras are Nijenhuis?
Leibniz algebras can be seen as a ``non-commutative" analogue of Lie algebras. Nijenhuis operators on Leibniz algebras introduced by Cariñena, Grabowski, and Marmo in [J. Phys. A: Math. Gen. 37(2004)] are (1, 1)-tensors with vanishing Nijenhuis torsion. Recently triangular Leibniz bialgebras were introduced by Tang and Sheng in [J. Noncommut. Geom. 16(2022)] via the twisting theory of twilled Leibniz algebras. In this paper we find that Leibniz algebras are very closely related to Nijenhuis op…
