there is a counrty list settings in the right panel, which you can select any country and add it to map

Just built a small tool and created some comparsion of country size vs. planets. Greenland seems larger than i thought.The tool allows you to drag a counry to other planet to see the size there.

thanks for the ux feedback, will ship a better version soon. by the way, there is a fullscreen model which the drag-and-drop experience might feel better

how does it work with more complex layout not just vertical list of items, like those drag-and-drop for visualization UI: https://github.com/Kanaries/graphic-walker
you can see that there are different areas of draggable and droppable, on different directions.
Re:SQLite JSON at Full Index Speed Using Generated Columns
on Friday December 12, 2025 @02:03PM (#46247469)
duckdb is super fast for analytic tasks, especially when u use it with visual eda tool like pygwalker. it allows u handles millions of data visuals and eda in seconds.
but i would say, comparing duckdb and sqlite is a little bit unfair, i would still use sqlite to build system in most of cases, but duckdb only for analytic. you can hardly make a smooth deployment if you apps contains duckdb on a lot of platform
does the model really improve? i tried several tasks today, and most of them failed, which are super easy ones.
maybe it's just because the gpt5.2 in cursor is super stupid?

Ask HN: How should new programmers learn in the AI era?
My younger brother just started learning programming. When I was learning, I spent weeks building small demos and exercises — calculators, todo apps, little games — but now, most of those can be built in seconds with AI assistants.I’m wondering: should new programmers still learn the same way we did — building everything by hand — or are there better ways to learn with AI tools around?Have you...
