Kommentar: Warum Brennstoffzellen-Autos nicht funktionieren
Trotz hoher Förderung bleiben Wasserstoffautos ein Nischenprodukt. E-Autos übertreffen sie längst in Reichweite und Infrastruktur, meint Gregor Honsel.

{purrr} has some lesser known functions that make handling of failing function calls easier: safely, quietly, possibly: #rstats

Wrap a function to capture errors — safely
Creates a modified version of .f that always succeeds. It returns a list with components result and error. If the function succeeds, result contains the returned value and error is NULL. If an error occurred, error is an error object and result is either NULL or otherwise.

New pre-print out: "Types, equations, dimensions and the Pi theorem".
We formalized the covariance principle (physical laws must be independent of units) as a homomorphism between the algebra of physical quantities and real numbers.
While the Pi Theorem from Dimensional Analysis (DA) is non-constructive, we introduce a constructive method for applying it. This could enable DA-driven program derivation where the type checker helps identify valid physical laws.

Smith says Trump "without question" added to the danger to Mike Pence's life with his 2:24pm tweet while the Capitol was under attack.

Bio-hybrid robots turn food waste into functional machines
EPFL scientists have integrated discarded crustacean shells into robotic devices, leveraging the strength and flexibility of natural materials for robotic applications.

I just finished Guild Wars: Prophecies. It took me 19.5 years.
I created my first character way back when the game was new, but I never finished the campaign. The upcoming Reforged update got me interested again. Together with a friend and 3 very friendly strangers we played through the remaining 3 missions.
From boss tactics to tounge-in-cheek comments about the dated cutscenes It was just the perfect MMO game night for me.

The honorable mention got me choked up. I'll admit... I never thought of that. 😢
