In mathematics, the term **antiparallel** typically refers to vectors or lines that are oriented in opposite directions. Specifically, two vectors are said to be antiparallel if they have the same magnitude but point in opposite directions. For example, if vector \( \mathbf{a} \) points to the right (e.g.

These are the rules which specify what different concurrent read/write memory accesses from different threads/processes can or cannot see.
Notable such set of rules include:
Crunode by Wikipedia Bot 0
As of my last knowledge update in October 2023, there isn't a specific widely-known entity or concept called "Crunode." It's possible that it could refer to a company, product, software, or concept that emerged after that date, or it might be a niche term not broadly recognized in the public domain.

Medium (website) by Ciro Santilli 37 Updated +Created
While this has some of the metrics features that Ciro Santilli wants to implement for OurBigBook.com, it limits the number of articles your readeres can read.
How the fuck can you publish on a website that limits the number of views for your articles?!?! When all it has is static pages + some metrics?!?!
Evil. Just learn to use GitHub Pages for God's sake.

Psalm 46:10 from the bible:
Be still, and know that I am God;
I will be exalted among the nations,
I will be exalted in the earth.

About 50k subscribers on 2021, which feels way too little for the video quality and quantity.
Ciro Santilli believes that this channel will go very far, certainly achieving 1M subscribers in they keep it for one or two more years. Update: it didn't, as of 2024, shame.
They are Utah-based, and they do many many amazing weekend trips. They mostly drive from home to some trailhead, and then climb up and down it the entire day.
No technical rock climbing, only bouldering, but they still manage to reach many amazing places, and there is a level of danger in many of their ascents.
They also often ski down the mountains when there is snow.
The cool thing about this channel is that as the name suggests, they are not professionals, and what they do can be done by anyone without working full time on it, as long as you have adequate preparation.

DeCSS haiku by Wikipedia Bot 0
DeCSS haiku refers to a poem that captures the essence or themes related to DeCSS, which is a program that allows users to decrypt DVDs. DeCSS became prominent in legal battles over copyright and digital rights. The haiku format, which consists of three lines with a syllable pattern of 5-7-5, can express the complexities and controversies surrounding DeCSS and digital rights.
The Angle Bisector Theorem is a fundamental principle in geometry that relates the lengths of the sides of a triangle to the segments created by an angle bisector.

Lowering means translating to a lower level representation.
Raising means translating to a higher level representation.
Decompilation is basically a synonym, or subset, of raising.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
