How to find if a customer is logged in or not in Magento 2.
If the customer is logged in then how to get customer data from a session?
I want to write a software design document for a new product `Chateval`, which can make it easier to evaluate generative AI systems (e.g., chatgpt and claude). Chateval can (1) provide many evaluation scenarios, from text writing to code and math, and (2) support many evaluation metrics, e.g. helpfulness, relevance and factuality. It not only provides developers with optimization directions, but also helps users use generative ai products such as chatgpt more reliably. Please help me finish the document that follows the structure:  [Overview],  [Goals], [Use Cases], [API Design], [Milestones], [Open Questions], [People].

I am from Kenya. Can I travel to the Netherlands to seek asylum with out a visa, because I want to seek asylum? Will Kenya Airways allow me to board a plane with out a visa to Schiphol Airport, considering I have my passport?

It is generally not possible to travel to the Netherlands without a visa for the purpose of seeking asylum. According to Dutch immigration law, you need a valid visa to enter the Netherlands, unless you are a national of one of the countries exempted from this requirement. Kenya is not included in the list of exempted countries.

Therefore, it is necessary for you to obtain a Schengen visa for the Netherlands from the Kenyan embassy or consulate before traveling to the Netherlands. This visa will allow you to transit through the airport and stay in the Netherlands for up to 90 days.
