Intel Cascade Cipher is a hardware-based encryption technology developed by Intel, primarily aimed at enhancing the security of data in transit and at rest. It is designed to support cloud computing and enterprise data center environments, where protection against unauthorized access and data breaches is crucial. Cascade Cipher operates by integrating cryptographic functions within Intel's hardware architecture, enabling secure data encryption and decryption processes to occur with minimal performance overhead. This allows systems using Cascade Cipher to maintain high performance while ensuring that sensitive data remains secured.
In category theory, an **additive category** is a type of category that has a structure allowing for the definition and manipulation of "additive" operations on its objects and morphisms. Here are the key characteristics that define an additive category: 1. **Abelian Groups as Hom-Sets:** For any two objects \( A \) and \( B \) in the category, the set of morphisms \( \text{Hom}(A, B) \) forms an abelian group.
Roscoe Circle is a term used primarily in the context of the Chicago area and may refer to several things, but it is most commonly associated with a specific intersection or neighborhood in the Roscoe Village area of Chicago, Illinois. In some contexts, it may also refer to a metaphorical or social concept rather than a physical location.
A **semi-abelian category** is a type of category that generalizes certain concepts from abelian categories while relaxing some of their requirements. Concepts from homological algebra and category theory often find applications in semi-abelian categories, especially in settings where one wants to retain some structural properties without having a full abelian structure.
csvkit by Ciro Santilli 37 Updated 2025-07-16
Lots of features, but slow because written in Python. A faster version may be csvtools. Also some annoyances like obtuse header handing and missing features like grep + cut in one go: csvgrep and select column in csvkit.

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
