"A Man of Misconceptions" is a historical novel written by Jon Steele, published in 2013. The book tells the story of the life and adventures of the 17th-century Englishman, the astronomer, and mathematician Thomas Harriot, who was a contemporary of Galileo and Kepler. Harriot is portrayed as a man ahead of his time, grappling with the scientific and cultural limitations of his era.
One-time pad by Wikipedia Bot 0
The one-time pad (OTP) is a theoretically unbreakable encryption technique that uses a key that is as long as the message being encrypted. Here are key characteristics and principles behind the one-time pad: 1. **Key Usage**: In the one-time pad, a random key or "pad" is generated. This key must be statistically random, as long as the message, and used only once.

TODO human presumably?
I don't think it has any advantage over KEGG however, besides historical interest? Maybe slightly more manual layout and so more beautiful?
James Somers (rightly) likes to point to it as a "biology is awesome" thing.

Online credentials for learning refer to various types of certifications, badges, diplomas, or degrees that individuals can earn through online educational programs. These credentials are often designed to recognize and validate a learner's skills, knowledge, and competencies acquired through online courses, workshops, or training programs. Here are some key aspects of online credentials: 1. **Types of Credentials**: - **Certificates**: Short-term programs that demonstrate mastery of specific skills or knowledge in a particular area.
Protein tag by Ciro Santilli 37 Updated +Created
You modify the DNA of a cell and stick a fluorescent protein right before or after another protein. Then when it gets translated, the GFP is stuck to the protein of interest, which hopefully hasn't lost its function as a result, then you can just see the protein of interest.
PGP word list by Wikipedia Bot 0
The PGP word list is a collection of human-readable words used in the Pretty Good Privacy (PGP) encryption system for generating passphrases and keys. It was designed to create memorable and easy-to-communicate phrases that can serve as reliable keys. The original word list contains 2,048 distinct words and is often used to create key fingerprints or passphrases that are more secure than random alphanumeric strings while remaining relatively easy for humans to remember and pronounce.

POODLE by Wikipedia Bot 0
POODLE stands for "Padding Oracle On Downgraded Legacy Encryption." It is a security vulnerability that affects SSL 3.0, a protocol used to secure communications over a computer network. The vulnerability allows an attacker to exploit weaknesses in the way SSL 3.0 handles padding in encrypted messages, enabling them to decrypt sensitive information such as cookies or other data transmitted over secure channels. The POODLE attack works by forcing a target to fall back to SSL 3.
In cryptography, padding is a technique used to ensure that plaintext data conforms to the required length for encryption algorithms, especially block ciphers. Block ciphers operate on fixed-size blocks of data (for instance, 128 bits or 256 bits), and if the plaintext does not fill up a complete block, padding is added to complete it.

Passphrase by Wikipedia Bot 0
A passphrase is a type of password that typically consists of a sequence of words or a longer string of characters that create a more complex and secure form of authentication. Passphrases are usually longer than traditional passwords, making them more resistant to brute-force attacks. For example, instead of using a single word or a short combination of letters and numbers, a passphrase might be something like "SkyBlueElephantDances123!" or "ToBeOrNotToBeThatIsTheQuestion".

There are two ways:
Password-based cryptography refers to cryptographic techniques that utilize passwords for the purpose of securing data, authenticating users, or generating cryptographic keys. This method relies on the assumption that the password, which is typically a string of characters created by the user, is known only to that user and serves as a means of encryption or decryption. Here are some key aspects of password-based cryptography: 1. **Key Derivation**: In many systems, passwords are not used directly as encryption keys.
Password strength by Wikipedia Bot 0
Password strength refers to how difficult it is for an unauthorized party to guess or crack a password. A strong password is essential for protecting personal and sensitive information from cyber threats, such as hacking and unauthorized access. Several factors contribute to password strength, including: 1. **Length**: Longer passwords are generally stronger. A good rule of thumb is to use at least 12 to 16 characters.
Philco computers by Wikipedia Bot 0
Philco, originally known as the Philadelphia Storage Battery Company, was an American company founded in the 1890s. Initially focused on battery production, the company diversified into various electronics and consumer products, including radios and televisions. In the mid-20th century, Philco became known for its innovations in electronics, and it expanded into the computer market.
Pizzino by Wikipedia Bot 0
"Pizzino" can refer to different things based on the context. Here are a few possibilities: 1. **Food**: In some regions, "pizzino" may refer to a small pizza or a type of pizza slice, often made as a snack or for individual consumption. It could also describe a specific style or preparation of pizza. 2. **Cultural Reference**: It might refer to a dish or product in a particular culture or cuisine, especially in Italian or Mediterranean contexts.

Pinned article: ourbigbook/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 5. . You can also edit articles on the Web editor without installing anything locally.
