50 Jahre Videorekorder: Sonys Betamax als erfolgreicher Fehlschlag
1975 brachte Sony die ersten Videorekorder für daheim auf den Markt. Es folgte der große Formatkrieg mit VHS, den Sony nur zum Teil verlor.

Airlines Don't Want You to Know They Sold Your Flight Data to DHS
A contract obtained by 404 Media shows that an airline-owned data broker forbids the feds from revealing it sold them detailed passenger data.

Geometric Floquet theory
We derive Floquet theory from quantum geometry. We identify quasienergy folding as a consequence of a broken gauge group of the adiabatic gauge potential $U(1){\mapsto}\mathbb{Z}$. Fixing instead the gauge freedom using the parallel-transport gauge uniquely decomposes Floquet dynamics into a purely geometric and a purely dynamical evolution. The dynamical average-energy operator provides an unambiguous sorting of the quasienergy spectrum, identifying a Floquet ground state and suggesting a way …

En trend som inte jag kände till det här. Men det är det vanligaste mönstret när det gäller det här. Någon har bara ljugit ihop en sak. Det blir populärt och andra influensers som är desperata efter "nytt material" kopierar det för sina egna klipp och sen börjar människor tror på det för att "alla säger det"

Bundestagsforscher: "Erhebliche Herausforderungen" für Flugtaxi-Betrieb
Technikfolgen-Forscher des Bundestags verweisen auf viele offene, vor allem regulatorische Fragen beim Praxis-Einsatz von Flugtaxis wie die Flugplatzpflicht.

Migrants placed on a deportation flight originally bound for South Sudan
are now being held in a converted shipping container on a U.S. naval base in Djibouti,
where the men and their guards are contending with baking hot temperatures, smoke from nearby burn pits and the looming threat of rocket attacks,
the Trump administration said.

Migrants and ICE officers contend with heat, smog and illness after detoured South Sudan flight
The Trump administration said the converted conference room in the shipping container is the only viable place to house the men on the base in Djibouti.

Optimization of Floquet fluxonium qubits with commensurable two-tone drives
Protecting superconducting qubits from low-frequency noise by operating them on dynamical sweet-spot manifolds has proven to be a promising setup, theoretically as well as experimentally . These dynamical sweet spots are induced by an externally applied Floquet drive, and various drive forms have been studied in different types of qubits. In this work we study the effects of using two-tone drives on the applied magnetic flux of the form $ϕ_{ac}(t)=ϕ_m\cos(mω_\mathrm{d} t)+ϕ_n\cos(nω_\mathr…
