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.

Classifies clichés in storytelling.
Every page is highly intelligent and interlinked to other pages.
It is incredible.
TuxGuitar by Ciro Santilli 37 Updated +Created
Just use MuseScore instead.
Can import from: MIDI.
Can export to:
Ubuntu 20.04:
sudo apt install tuxguitar tuxguitar-alsa tuxguitar-jsa tuxguitar-oss
tuxguitar-jsa was needed, otherwise no sound: askubuntu.com/questions/457321/tuxguitar-no-sound-in-14-04
Has OK step sequencer non-realtime up/down/left/right guitar based composition interface.
Has chord insertion.
Has bend editor.
Could be more amazing, but it is OK.
A bit limited by being very "guitar oriented". Shows you guitar strings, and you enter offset to each string. So to enter two adjacent notes you need to use two seprate strings and thing about the offsets. If only it had a more piano based interface.
Drum notation is also atrocious, you have to go to the top chord, and use high numbers starting at 36.
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.
Turing machine by Ciro Santilli 37 Updated +Created
The dominating model of a computer.
The model is extremely simple, but has been proven to be able to solve all the problems that any reasonable computer model can solve, thus its adoption as the "default model".
The smallest known Turing machine that cannot be proven to halt or not as of 2019 is 7,918-states: www.scottaaronson.com/blog/?p=2725. Shtetl-Optimized by Scott Aaronson is just the best website.
A bunch of non-reasonable-looking computers have also been proven to be Turing complete for fun, e.g. Magic: The Gathering.
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.

Turing Award by Ciro Santilli 37 Updated +Created
More like a "lifetime achievement" though, rather than the Nobel Prize, which tends to be for more specific achievements.

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.
"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.
tshark by Ciro Santilli 37 Updated +Created
Sample usage:
sudo tshark -f 'host 192.168.1.102
This produces simple one liners for each request.
What you likely want is the -V option which fully disassembles each frame much as you can do in the GUI Wireshark:
sudo tshark -V -f 'host 192.168.1.102

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.
