Hiromichi Kataura does not appear to be a widely recognized figure or term as of my last update in October 2023. It is possible that he could be a private individual, a character from a specific work of fiction, or involved in a niche subject not captured broadly in public knowledge.
Keiji Kikkawa is a well-known Japanese biochemist and a prominent researcher in the fields of molecular biology and biochemistry. His work primarily focuses on signal transduction, particularly the molecular pathways involved in cell communication and response to external stimuli. Kikkawa has made significant contributions to understanding how cells regulate various biological processes, which has implications for fields such as cancer research and developmental biology.
Yoshio Nishina (1890–1951) was a prominent Japanese physicist known for his contributions to the fields of nuclear and particle physics. He is often regarded as one of the founders of modern nuclear physics in Japan. Nishina played a significant role in the development of the first cyclotron in Japan and conducted important experiments in cosmic ray physics. He is also well-known for his involvement in the Japanese atomic bomb project during World War II.
**Architectonic tessellation** and **catoptric tessellation** are terms related to specific types of geometric patterns or arrangements, though they might not be widely recognized in all fields of study. Let's break these down: 1. **Architectonic Tessellation**: - This refers to a type of tessellation that is inspired by architectural forms and structures. It often involves the arrangement of shapes that can suggest elements of architecture, such as walls, roofs, or other building components.
The Conway group \( Co_1 \) is one of the five Conway groups, which are a class of sporadic simple groups named after mathematician John Horton Conway. Specifically, \( Co_1 \) is the largest of these groups and is denoted as the first of the Conway groups.
Roe v. Wade is a landmark decision by the United States Supreme Court, decided on January 22, 1973. The case established a woman's legal right to have an abortion under the constitutional right to privacy. It was brought by "Jane Roe," a pseudonym for Norma McCorvey, who challenged Texas laws that criminalized most abortions.
Weibel's conjecture is a statement in algebraic K-theory proposed by Charles Weibel. Specifically, it concerns the K-theory of rings and states that for any commutative ring \( R \) with a unit, the K-theory group \( K_0(R) \) is isomorphic to a certain direct sum involving the Grothendieck group of finitely generated projective modules over \( R \).
"Preiddeu Annwfn," sometimes translated as "The Spoils of Annwfn," is a poem found in the "Book of Taliesin," a collection of medieval Welsh poetry. It is attributed to the legendary bard Taliesin and is considered one of the most important works of early Welsh literature. The poem describes a journey to Annwfn, often interpreted as an Otherworld or the realm of the dead in Welsh mythology.
Setne Khamwas and Si-Osire are characters from Egyptian literature, specifically found in a story that combines elements of mythology, magic, and adventure. These narratives are part of the body of ancient Egyptian stories and often reflect cultural themes, such as the quest for knowledge, the power of the divine, and the relationship between the human and the supernatural.
Authenticated Key Exchange (AKE) is a cryptographic protocol that enables two parties to establish a shared secret key over an insecure communication channel while also verifying each other's identities. This process is critical in ensuring both confidentiality and authenticity in secure communications. Key features of Authenticated Key Exchange include: 1. **Key Establishment**: AKE protocols allow two parties to generate a shared secret key that can be used for encrypting subsequent communications.
Keybase is a secure messaging and file-sharing platform that emphasizes privacy and encryption. It was designed to provide users with a safe environment for communication and collaboration. Keybase combines several features, including: 1. **End-to-end Encryption**: All messages and files shared on Keybase are encrypted, ensuring that only the intended recipients can read them.
Forward secrecy (also known as perfect forward secrecy, or PFS) is a property of certain secure communication protocols that ensures the compromise of long-term keys does not compromise past session keys. In other words, it guarantees that even if a server's long-term private key is exposed, previously established session keys remain secure and cannot be decrypted.
A Keyfile typically refers to a file that stores cryptographic keys, often used in various software applications for encryption, authentication, or data protection. The term can encompass different contexts based on its use: 1. **Encryption**: In the context of encryption software, a Keyfile may contain the keys necessary to decrypt data or files that have been secured using a particular algorithm. This file can be used alongside a password or passphrase to enhance security.
Terminal emulator by Ciro Santilli 40 Updated 2025-07-16
Once upon a time young Ciro Santilli spent lots of time evaluating the features of different terimnals. The many windows of Terminator. The pop-uppiness of Guake/Yakuake.
But then one day he met tmux, and he was enlightened
Terminal choice doesn't matter. Just use tmux.
In mathematics, "Clasper" refers to a tool or device used in the study of knot theory and low-dimensional topology. Specifically, a clasper is a specific type of graph-like structure that can be used to manipulate knots and links. Claspers can be thought of as a generalization of the notion of a "knot insertion" and are used to define operations that can alter the topology of a knot or link.
This is the most important thing to understand Git!
You must:
  • be able to visualize the commit tree
  • understand how each git command modifies the commit DAG
There are two ways to organize a project:
Some people like merges, but they are ugly and stupid. Rebase instead and keep linear history.
Linear history:
5 master
|
4
|
3
|
2
|
1 first commit
Branched history:
7   master
|\
| \
6  \
|\  \
| |  |
3 4  5
| |  |
| /  /
|/  /
2  /
| /
1/  first commit
Here commits 6 and 7 are the so called "merge commits":
  • they have multiple parents:
    • 6 has parents 3 and 4
    • 7 has parents 5 and 6
  • they are useless and don't contain any real information
Which type of tree do you think will be easier to understand and maintain?
????
????????????
You may disconnect now if you still like branched history.

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.
    Figure 2.
    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
