> Haven't seen that in many other cities.

Really? In my limited experience in Europe I've often seen attendance to museums are free. When we were in Ireland and Scotland, most museum/galleries were free with suggested donations. In contrast, museums in Italy had fees for attendance.

I know here in Spain, most attractions run by Museos Estatales are free on Saturday PM and Sundays, but some are also free every day (e.g. Museum of Fine Arts here in València).

Granted, that's a very limited subset of European countries/cities, I'd be interested in the pricing structure of other European countries/cities because we are definitely planning to travel in Europe more often now that we live here.

As a sidebar, I can't recommend The Chester Beatty museum enough - https://www.chesterbeatty.ie

Currently have part-time/fractional availability for independent consulting/contract work. Recent work has involved AI integrations (LangChain, LangGraph, FastMCP), data pipelines, CI/CD workflow automations, etc. 15+ years of experience in software development.

I haven't done exhaustive testing of all top-performing models on the HF Embedding Leaderboard (https://huggingface.co/spaces/mteb/leaderboard) but I have tested a number of them extensively in the past month or two. The two best API provider models I've tested are:

- JinaAI (https://jina.ai/embeddings/) v3 and v4 performed well in my testing. - Google's Gemini-001 model (https://ai.google.dev/gemini-api/docs/models#gemini-embeddin...).

Overall, both were surpassed by Qwen3-8b (https://huggingface.co/Qwen/Qwen3-Embedding-8B).

Note, this was specifically regarding English and Code embedding generation/retrieval, with reranking.

IMO the PyTorch getting started tutorials are really good (https://pytorch.org/tutorials/beginner/basics/intro.html).

A classifier for handwritten digits in the MNIST dataset is generally considered the "Hello World" of neural networks. I went over it in a course, but there are countless tutorials to be found online, i.e. https://www.digitalocean.com/community/tutorials/introductio...

Once you begin to understand how to handle data and how to define layers, you can start playing around with whatever your heart desires. The rabbit hole is vast and endless :)
