Colab
I observed that some universities across Europe relays only on Google Colab to make, test, synch, share code during their classrooms.
The idea is to have some kind of interface, similar to what google does, to be able to develop code, test it's functionalities, store sources at drive (text based files), and even better if Lumo can help developing code as Gemini does.
Having such a tool can be a good argument to induce EU agents to switch from their current US based big techs providers, to a secure development platform, thinking in necessary privacy for research and investigation topics.
For regular users or regular students, can be a good to experiment with Python for instance, not relying on Google for such a proposes.
