Tomatoes in Winter

I think my tomato plants are still hanging onto summer, look at the harvest I got on Friday. A couple of plants died but the rest are producing new flowers. The weather was warm for the past week in SoCal, I still have about 20-30 tomatoes slowly ripening.

My one and only pumpkin harvest. I cooked it in the oven, removed the pulp and stored in the refrigerator, will be making pumpkin soup soon.

What is this?

I have no idea what kind of gourd or pumpkin is this. Any ideas?
