    The biggest factor IMO is something no one mentioned yet: we can only see one face of each step (either the top or the wall). If a photo is taken from the bottom, we would almost always be able to see the tops of the first few steps, which isn’t visible here. If a photo is taken from the top, the walls would pretty much never be visible (if they were, you could also see the photographer’s feet).

    Therefore, this photo is only consistent with a photo taken from the top.

    It is possible that this is an extremely long flight of stairs or that the photo was taken from a deliberately deceptive angle, but if that’s the case I have to say it was expertly done, because I am CERTAIN that we are looking from the top and the mattress is at the bottom.



  • Interesting. My parents’ apartment had carpeted stairs when they bought it (when I was around 3). About a decade later they completely renovated the kitchen and naturally the renovations creeped into other parts of the home. One of the builders showed them that underneath the carpet were beautiful stone steps. They instantly decided to take out the carpet, and the stairs are bare to this day. Here’s a photo I took just now (obviously from the bottom looking up):



  • Back when I thought it was two mattresses, I thought it couldn’t be at the top because the right mattress probably wouldn’t be held up like that. But since it’s one mattress, it can relatively easily be held at that angle with most of its weight resting on the step.

    And that’s my main reason: it really seems like the mattress is being pushed towards that step, and I believe it’s being pushed by gravity. Doesn’t make as much sense for it to be pushed in that direction by someone.

    I’m not married to it though, it’s a really tricky picture.


  • I think it’s bottom too but I don’t agree with your reasoning, I’ve seen steps without that bit.

    Edit: actually now I think top, I’ve been convinced by the daylight argument plus the realization that is a single mattress folded in half (I previously thought it’s two mattresses).

    Edit: changed my mind again, made a top level comment



  • I think SQLite is a great middle ground. It saves the database as a single .db file, and can do everything an SQL database can do. Querying for data is a lot more flexible and a lot faster. The tools for manipulating the data in any way you want are very good and very robust.

    However, I’m not sure how it would affect file size. It might be smaller because JSON/YAML wastes a lot of characters on redundant information (field names) and storing numbers as text, which the database would store as binary data in a defined structure. On the other hand, extra space is used to make common SQL operations happen much faster using fancy data structures. I don’t know which effect is greater so file size could be bigger or smaller.








  • Not if it’s measured with a fractional part.

    I wonder if the rate is high enough and the distances large enough that relativity could make it so people on opposite ends of the world disagree on which baby was born first. Then again, birth takes a lot longer than a second and it’s not really possible to pinpoint an exact timestamp when the baby is born and wasn’t previously.
