Cache replacement policies are algorithms used in computer systems to determine which data should be removed from a cache when new data needs to be loaded. Caches are small, fast storage areas that hold copies of frequently accessed data to improve performance by reducing access times to slower main memory. When a new item must be loaded into the cache and there is no space available, a replacement policy decides which existing item should be evicted.
Pseudo-LRU (Least Recently Used) is a caching algorithm that aims to approximate the behavior of the true Least Recently Used strategy while avoiding the overhead associated with maintaining strict recency tracking for each cache entry. In typical LRU implementations, the system keeps track of the exact order in which items are accessed, which can be complex and resource-intensive, especially in systems with large caches. Pseudo-LRU simplifies this by using a simpler structure that can still offer reasonable approximations of LRU behavior.
Robert Fountain is known as a mental calculator, recognized for his remarkable ability to perform complex mathematical calculations in his head without the aid of tools, such as calculators or paper. He is often celebrated for his speed and accuracy in mental arithmetic, participating in competitions and events that showcase mental calculation skills. Fountain's feats are often seen as demonstrations of extraordinary cognitive abilities, and he may utilize various techniques, such as mnemonic devices, pattern recognition, and visualization strategies, to enhance his mental calculation capabilities.
Salo Finkelstein is not a widely recognized figure in popular culture, history, or notable events, as of my last update in October 2023. It's possible that Salo Finkelstein could be a private individual, a fictional character, or a reference from a more niche domain.
Willis Dysart does not seem to be widely recognized as a prominent figure, company, or concept in mainstream knowledge up to my last update in October 2023. It is possible that Willis Dysart is a lesser-known individual, a fictional character, or a topic that has emerged more recently.

Pinned article: Introduction to the OurBigBook Project

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.

    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
