I'm creating a 3d scene using a-frame (https://aframe.io) and I need some sort of way to mirror an html div onto a plane inside a-frame. For example, lets say that there is a div with some code where I can draw on it similar a whiteboard on the bottom left corner of the screen. Everything that I draw on the whiteboard should be mirrored to the a-frame plane. That way I should be able to see my whiteboard drawing in my a-frame scene.

I've tried using two components the a-frame html embed component (https://github.com/supereggbert/aframe-htmlembed-component) and the a-frame shader component (https://github.com/mayognaise/aframe-html-shader) and both work for displaying html in my scene on a 2d plane however the 2d plane in my scene doesn't mirror the whiteboard and doesn't update. That means when I draw something on my whiteboard, instead of mirroring onto 2d plane and showing what I've drawn in vr, there is just a whiteboard with nothing drawn on it.

I need to be able to create a div in html with a whiteboard or other code on it and have the same html be displayed on a 2d plane in my scene. The 2d html on the plane should update meaning if I draw the letter "a" on my whiteboard, the letter a will appear on the 2d plane in my scene. As long as there is a div where I am able to put my 2d html (my whiteboard) and the div mirrors in vr, that would be the ideal solution. Is there some code that could accomplish this?

Am I missing something with the two component I've tried that allow me to accomplish this? (Two components: https://github.com/supereggbert/aframe-htmlembed-component and https://github.com/mayognaise/aframe-html-shader) Or maybe a different A-frame component?

Ideally I am seeking the code for a component that allows me to mirror a div onto a 3d plane in my scene, or recommend a component that allows me to display interactable content on a 2d div.

We want to render text that looks like this:

1. Introduction. Here is a named section.

This section has a second paragraph.

2. This one does not have a name. It is logically a part of the Introduction.

3. The second section. This one does have a name.

4. This (unnamed) section is part of a group beginning with “The second section”.

5. This one is too.

The ideal markup for this example would be

I have the following data in a Postgres table that I need to flatten out:

I'm trying to make a simple puzzle system for a game involving beams of light and mirrors in Unity. The light beams are created using an empty GameObject that casts a Raycast2D and uses a LineRenderer to display the beam. When a beam collides with a mirror object I simply use Vector2.Reflect to calculate the new direction.

The implementation works fine when the mirrors are static. When I try to move them around in-game, it causes random stack overflow errors, and there doesn't seem to be a pattern. Here's an example of a working mirror setup:

Here's what happens when I try to move a mirror:

I'm guessing it's due to the mirror somehow reflecting the beam back and causing an infinite reflection loop, but I'm not sure why that would happen.

Relevant code:

I am making a program in C language that aims to identify if two binary trees are mirror. In my program I have managed to create two trees with the structure that can be seen in the following image:

My problem is that I don't know how to create a recursive method to verify that the two binary trees are mirrored, one with respect to the other; I have tried to create the method, but I only manage to compare the root of the two binary trees, I can't get beyond the beginning.

Attached is the code I have so far.

This is an instructional question and not a procedural one as simply requiring "fmt" works just fine, but when with the hello world golang file I modify it as follows

I'm currently working on a program in Selenium that is gathering up URLs from a website that splits it's hosted content into mirrors, each mirror containing a variable amount of parts. Due to the website in question having very unreliable CSS selectors (changes per page, basically), alongside basically no classes/IDs/names in the HTML to work with, I've rigged up a rather complicated system.

Essentially, each page delivers a variable amount of parts, anywhere from 2 to 20+. So, I've setup a part checker that scans the page for instances of the word Part (from Part 1, Part 2, Part 3, etc) and removes duplicates as a method to count how many of these parts are present across every mirror. For example, if there are 7 parts in each mirror, my code will append Part 1-Part 7 to a list and remove any duplicate mentions of other parts.

Then, assigning that list's len() to a variable, I now have a variable with an integer value equal to the number of parts for each mirror. A little complicated, but it suits my needs well enough. Now, here is my problem:

I have two completed lists I would like to zip together into one dictionary, one list contains the names of the mirrors and the other contains all part URLs on the page. I would like to use this len()-defined variable that I assigned previously as a guide for how many URLs I want to iterate to each mirror key. Using the example above, lets imagine a page with 7 URLs per mirror.

I want my dictionary to end up looking something like this: (Please note, the zip code at the top I am using is intentionally incorrect, but helps, I hope, illustrate my goal in a more roundabout way)

I'm building an Electron app that manages a collection of photographs on an NAS. That NAS has two logical volumes, named "alpha" and "beta". For reasons I want to understand (and fix!), my app gets an ENOENT error whenever it tries to run CLI tools against files on beta, but not when it runs CLI tools against alpha. Additionally, it is permitted to perform regular FS operations (e.g. readdir, stat, even rename) against files on both volumes without error. For example: the app first learns about the files on beta because it scans the filesystem using find; that scan succeeds.

I'm using the CLI tool exiftool to extract image metadata from all these files (e.g. dimensions, capture device, etc). Here's the command my app runs, using child_process.spawn:
