    1. A tree with ‘n’ vertices has ‘n-1’ edges.
    2. The edges of a tree are known as branches. Elements of trees are called their nodes. The nodes without child nodes are called leaf nodes.

    1. In computer science, a tree is a widely used abstract data type that simulates a hierarchical tree structure

      a tree (data structure) is the computer science analogue/dual to tree structure in mathematics

    1. Title: "goal the use case is trying to satisfy"[23]:101 Main Success Scenario: numbered list of steps[23]:101 Step: "a simple statement of the interaction between the actor and a system"[23]:101 Extensions: separately numbered lists, one per Extension[23]:101 Extension: "a condition that results in different interactions from .. the main success scenario". An extension from main step 3 is numbered 3a, etc.

      Not sure why I find this example so interesting.

      Probably because it is a human-readable outline that uses machine-readable (programming language source code) constructs, namely loops/iteration.

      The format in which this is written in, then, is itself a kind of (high-level, human-oriented) programming language.

      Example:

      • numbered list of steps [introduces/names the loop/iterator/enumeration being done]
        • Step: "a simple statement of the interaction between the actor and a system" [defines the inner part of the loop that gets "executed" once per iteration]

    1. With the advent of JavaScript modules (import and export), it's possible to build libraries that are tree-shakeable. This means that a user of your library can import just the bits they need, without burdening their users with all the code you're not using.
    2. If tree-shaking still fails, it's because Rollup thinks that there are side-effects somewhere in your code.
    3. Avoid transpilers like Babel and Bublé (and if you're using TypeScript, target a modern version of JavaScript)
    4. Don't create instances of things on initial evaluation — instantiate lazily, when the functions you export are called

    1. Tree-shaking is the process of analyzing the code files that are required to run your application and then including only code that is actually used by your application.

    1. Provides state management for tree-like components. Handles building a collection of items from props, item expanded state, and manages multiple selection state.
    1. My first thought was that the house had caught fire, and I would arrive only to a scorched ruin and blackened bone, but as we got closer I could see that it was a single tree that was burning. A gnarled and ancient elm, that sat removed from the rest of the forest. A small crowd surrounded the spectacle. One man, who I took to be a groundskeeper, stood closer than the others, with a lit torch in his hand. On my instruction, the driver pulled closer, though the horses were nervous, and I asked the man why they were burning the tree, when the rain was coming down so heavily. Surely it could have waited for drier weather. The man simply shrugged. My German is… fine, though I have had little cause to use it of late, but his accent was thick, and all that I could get from him was a sense of… resignation, and the insistence that his master, who I took to be Albrecht, wanted the tree dead. I’m sure that he used that word, though. Not burned, not removed, or destroyed. Dead. I resolved to ask Albrecht about it when I saw him.

      Creepy tree! Maybe similar to the HTR tree?

    1. Tree of Life

      The 'Tree of Life' has been present throughout many cultures and religions across history. It has been known by many different names but the meaning is always a source of life or a creator. The ancient Egyptians, Christians, Myahs, and Assyrians all believed in this 'Tree of Life.'

    1. The neighbour‐joining tree was prepared with the R package {Ape} (Paradis, Claude, & Strimmer, 2004) and visualized using the R package {ggtree} (Yu, Smith, Zhu, Guan, & Lam, 2017).
    1. Let's say you import { Interface } from "api/interfaces", from source file /src/views/View.ts. Typescript would then look for the module in the following paths: /src/views/api/interfaces.ts /src/api/interfaces.ts /api/interfaces.ts

    1. mark the workers as permanent or transient, so that if they fail they get restarted

      restart defines when a terminated child process must be restarted.

      • A permanent child process is always restarted.
      • A temporary child process is never restarted (even when the supervisor's restart strategy is rest_for_one or one_for_all and a sibling's death causes the temporary process to be terminated).
      • A transient child process is restarted only if it terminates abnormally, that is, with another exit reason than normal, shutdown, or {shutdown,Term}. https://erlang.org/doc/man/supervisor.html

    1. Start the branching with 4 powers of 2: 20, 21, 22 and 23

      We branch with these powers because the prime factorization has \(2^3\). If it were instead \(2^5\), we would branch with \(2^0\), \(2^1\), \(2^2\), \(2^3\), \(2^4\), and \(2^5\), and we would have a branching factor of 6.

    2. Double click on a project/context select all there sub-projects/contexts, therefore show their tasks
    3. arborescence

      First sighting of word arborescence. I thought they were just doing that for fun, as a play on "tree", but I guess it's a real graph theory concept (https://en.wikipedia.org/wiki/Arborescence_(graph_theory)).

    1. Vim does not only offer unlimited undo levels, later releases support an undo tree. It eventually gives the editor VCS-like features.

    1. In order to maintain this property, each node has a rank, which indidates the length of the path between the node and the right most leaf. For example,

      Rank - https://en.wikipedia.org/wiki/Leftist_tree#S-value

      Rank of a node, is the distance from that node to the nearest leaf in the subtree rooted at that node.

    1. Let's briefly look at the libraries, use cases, and factors that might help in deciding which is right for you. Here's a high-level decision tree: If you want fast and easy setup and integration, then component-playground may be the ticket! If you want a smaller bundle, SSR, and more flexibility, then react-live is for you! Here are the various factors at play:

    1. The original trees eventually died, but not before new sprouts could take root. For over 130 years, trees have continued to sprout, grow, and die in a so far endless cycle atop the courthouse

      Very odd claim to fame!

    1. Saussure stresses that signs arc arbitrary and without inherent meaning

      Saussure is that guy with the tree picture.

      You know . . .

      . . . that one. I figure this image is more important to knowing who he is than a picture of his face.

    1. select proprietary or out-of-tree modules (ex. vitualbox, nvidia, fglrx, bcmwl, etc.)

      If anyone is wondering what other modules they refer to, or how to discover any on your own system, this StackExchange thread on how to identify out-of-tree modules might help.

    1. This article mentions beating the tree [http://www.whitedragon.org.uk/articles/wassail.htm]

      If there is some historical accuracy in that account, I wonder if it should be included in this section.

    1. No mention of this in the Wikipedia article on Wassailing and I wonder if there should be?
