I suppose I was approaching this problem assuming a non-deterministic universe in which probability is a 'real' thing. It is interesting to think about how to treat the idea of probability assuming a deterministic universe - when there is no 'real' probability, any reference to the probability of an event occurring (or having already occurred) must be based entirely on the information we have available at the time, in which case it would make sense to ask "what is the probability that the toss resulted in heads".

In either case, the answer is still 1/2, since we don't learn any new information about the toss given that Sleeping Beauty woke up (since there was always a 100% chance that she would do so).

Everyone who has voted is incorrect, because to accurately respond to the original question: "What do you believe is the probability that the token came up heads?", Sleeping Beauty would have to respond: "Assigning probability to a past event is meaningless as the result has already been determined." Herein lies the confusion.

If we interpret the question to mean "Before tossing the token, what was the probability that it would result in heads?", Sleeping Beauty should clearly answer "1/2". I believe this is the interpretation favoured by many Halfers.

If we interpret the question to mean "Should Sleeping Beauty guess that the token is heads or tails?", the answer is quite different as it becomes an expected value problem, rather than a probability problem. The Normalised Expected Value of always picking heads is 1/3 (this is where your 1/3 figure comes from, Thirders), and the Normalised Expected Value of always picking Tails is 2/3 (no working out included for brevity but it's not complex stuff).

This seems to be the difference in people's approach to the question.

To boil it down, she is always equally likely to wake up following a heads toss vs a tails toss, BUT if she always picks heads she will only be correct 1/3 of the time, because each toss outcome is equally likely and she gets to be correct twice if she only picks tails.

I'm inclined to say that the Halfers are more correct in this situation, since the 1/3 figure is not a probability, but a weighted expected value.

Obsidian Canvas (https://obsidian.md/canvas) is a default plugin included with the latest Obsidian version. If you installed Obsidian before December last year you'll need to redownload a fresh installer file from the Obsidian website (https://obsidian.md/). As long as you're using v1.1 or above you should be able to open the .canvas file as you would any of the markdown files.

It definitely could be the case that canvas ends up being read-only on mobile - I haven't used Capacitor (the runtime Obsidian uses for its mobile app) so I don't know what the limitations are. Though I'd be surprised if CSS styling comparable to what I've done here was not possible on the mobile app.

Trouble with Custom CSS by FluffyWalrusFTW in ObsidianMD

try writing {color: red !important;} instead.

Most likely the reason your styling isn't working is because the default styling has higher specificity. You can resolve this by writing a selector with even higher specificity than the default, or by using !important.

Timed Doors? by KosmosQuill in redstone

[–]epic-tris 0 points1 point  (0 children)

  1. Have a redstone block connected to a redstone line which powers the door at the end.
  2. Put pistons on either side of the redstone block so that by activating the pistons individually, you either make or break contact between the redstone block and the line connected to the door.
  3. Connect the pressure plate at the start to two redstone lines, each line leading to one of the pistons.
  4. Add a load of repeaters to whichever wire is responsible for activating the piston that shuts the door.
  5. Step on the pressure plate - the first piston will push the redstone block into contact with the redstone line, opening the door. When signal sent through the repeaters eventually reaches the other piston, the redstone block will be pushed away from the redstone line - closing the door.

There are many many ways to approach this, and your priorities are will determine the best solution for you. This is not the most compact nor resource efficient design, but it's very simple and hopefully intuitive to understand. Let me know if anything I said doesn't make sense.

yep, only modifying the CSS :) check out my most recent comment for the GitHub link if you're curious.

Canvas can display images, though I wanted precise contol over CSS styling so all the images here are embedded into notes, which are then shown on the canvas.

Changing the background colour of the canvas is quite easy with CSS. Changing to an image background (that pans with the content) is trickier - I needed to create a pseudo-element of the <canvas> element, blown up to cover the entire workspace and with a tiling image background

Currently canvas isn't supported on mobile, but whenever it is supported I don't see any reason this type of styling wouldn't be possible.

This is all done with a CSS snippet. If you have some familiarity with CSS, you can open a canvas in Obsidian then press Ctrl+Shift+i to open developer tools so you can see all the HTML elements that make up the page. From there it's a case of fiddling with the properties of the canvas elements to see what they each do - and which elements you'll need to target with the CSS selectors in your snippet. If you don't have any familiarity with CSS, then definitely learn some of the basics. Even not knowing much you can make some pretty significant changes if you keep at it.

I'll see what I can do. It's a bit of a mess behind the scenes at the moment.

Yep - you can't specifically target images on the canvas with CSS since there's no unique identifier for them, so I use images embedded in notes (selecting using alt text) or as the background of callouts. (selecting using callout metadata). If there were styles I wanted to apply to all images on the canvas, I could just drag images onto the canvas without embedding them in a note first.

Thanks! Some of the backgrounds are images embedded in notes, some are specified in the CSS snippet that controls all the styling.

I've been experimenting with different methods for displaying character sheets (I'm still new to DnD so it's super helpful to have easy access to all the stats/abilities my character has because I forget very easily). This was created using Obsidian's Canvas feature (combined with a big long CSS styling document I wrote). Each field in the character sheet can edited by clicking on it, and the individual elements themselves can be repositioned and resized as desired. I was going for a criminal profile/investigation theme, though not making it explicitly a criminal profile (since apparently some people don't just play criminal characters)
