I feel that physical change the moment I saw my son first time. Something snapped/connected in my brain. I will do anything for that little thing. The feeling is visceral. It is very hard not to preach your best experience to others

Hey thanks for checking it out! Really glad the site has more audience than me and my son only and appreciate the feedback! Mind if I ask which mode were you playing? Was it "Find a country" or "Guess a country"? It migh

If you read this message, can you provide more context please? Are you choosing the "Name the country" mode with question from "Same continent". It might be that south america has only 13 countries in my database, so it

If you are not mindful, the tests it generates is just a re-implementation. Nothing was tested but every future change needs to modify two places

Nicely made! I thought I'm good with flags, and then there come a question of jordan, palestine and two more similar flags. I made a similar but uglier little party game https://geo-dude.com for my kids. Supports up to 4 pl

I wrote the faceblurring. It didn’t work on multiple faces when I first processed the videos. Thanks for pointing out, I should have blurred them

Solid feedback, thanks! 1. is very doable. My local gym uses an app to manage monthly leaderboard already and people seem to like it. There is a friendly rivalry in my local gym where people "fight" for the top spots 2. A lot can

On route rotation, maybe the gym will be responsible for uploading the scan. My local gym uses an app to manage route. People view what route is available on a wall. It is just a label saying "red is a V4", no photos, and every m

Climbing gym photogrammetry. My idea is that route and climb recordings is best recorded against a 3D climbing gym model, rather than a plan video, and technology has gotten good enough to do with a regular phone. As a climber myself, to cl

Tangential, for static site like this, why do people choose to host on vercel instead of github page?

Writing code with real use is very different from writing code for the sake of writing (looks cool, sounds cool). Writing code with one user is the base case of a “why am I writing this” recursion - because I use it. Every action leads to n

Accurate reconstruction is entirely up to the camera's ability to orbit around the object. If we are talking about cracks, the visual signal will be very poor as we can't wiggle a camera inside a crack. On the other hand, if we wa

My own set of heuristics 1. Use less subagents. The act of using subagent already needs dumping adequate amount of context for subagent to work effectively 2. Refactor when file grows large. Reasonably scoped files is easier to understand,
