In statistics we call it "conditional independence", attachment style is independent from maternal relationship if we know childhood friendship outcomes.
I think sequel kids, more than anything, benefit from having a trailblazer to refer to. It's no doubt true that parents get better at the job, but kids learn from demonstration. Older sibling is hypersensitive and has a hard time keeping friends around -> I better learn to swallow my pride. That kind of thing.
Sorry but this is legitimately a terrible way to encode this data. The number 0.8 is encoded as base64 encoded ascii decimals. The bits 1 and 0 similarly. URLs should not be long for many reasons, like sharing and preventing them from being cut off.
Links with lots of data in them are really annoying to share. I see the value in storing some state there, but I don’t think there is room for much of it.
What makes them annoying to share? I bet it's more an issue with the UX of whatever app or website you're sharing the link in. Take that stackoverflow link in the comment you're replying to, for example: you can see the domain and most of the path, but HN elides link text after a certain length because it's superfluous.
