Show HN: String Flux – Simplify everyday string transformations for developers

I built https://stringflux.io/ to make everyday string transformations a little less painful. It’s similar to CyberChef in the sense that it supports multiple string operations, but with a cleaner, more focused UI and smart suggestions based on your input.

Budeme měnit současný nejjednodušší kosmologický ΛCDM model?

Nová pozorování naznačují, že nejen Hubblova konstanta, ale také kosmologická konstanta, nejsou ve skutečnosti konstantami. Zejména nedávné analýzy dat ze spektrometru DESI silně naznačují, že se kosmologická konstanta Λ v průběhu rozpínání našeho vesmíru mění. Je proto velmi pravděpodobné, že brzy dojde k revizi stávajícího jednoduchého kosmologického ΛCDM modelu. http://www.osel.cz/14103-budeme-menit-soucasny-nejjednodussi-kosmologicky-cdm-model.html
