At the cafe. I left two hours early. Felt down. I think it's the heat. Can't bare it. Managed to fix the duplicate bug. It is still unclear why my code changes fixed it so I asked a question to the library maintainers. Although, I expect their answer to be no. Strange. Very strange. Though, it works. No more duplicates.

Read arXiv papers. Now I'm going to drink my smoothie. It's a mix to energise oneself. Let's see if it works.

Other than that, going to relax.
