This is a good thing. It basically contains an entire website, with HTML and assets inside a single ZIP, and a little bit of metadata.
It is incomprehensible why browsers don't just implement it as they already have all the web part, and also ZIP stuff:
The situation is so sad. Ubuntu 21.04 doesn't come with a reader installed by default:

It's not super easy to use at first.
And it sometimes says that the basic drawing thing you want to do is off the project's scope.
But as you learn more about it and further generalize the concepts, there are often reasonable reasons for those design choices.
And the UI looks good :-)
Examples:
Weld-On is a brand known primarily for its adhesives, solvents, and cements, particularly designed for bonding plastic materials such as PVC, CPVC, and ABS. It is widely used in plumbing, automotive, and construction industries for connecting pipes and fittings securely. Weld-On products generally provide strong, solvent-welded joints that can withstand high pressure and are resistant to various chemicals.
The "Evelyn effect" is not a widely recognized term in scientific literature or popular discourse as of my last knowledge update in October 2023. It could potentially refer to specific instances or phenomena in various fields, including psychology, sociology, or observational effects in certain studies, but it is not a standard term or concept.
Passive binding is a term that can have different meanings depending on the context in which it is used. Here are a couple of common interpretations: 1. **Biochemistry/Molecular Biology**: In the context of biochemistry or molecular biology, passive binding often refers to the non-covalent interactions between molecules, such as proteins or nucleic acids, that occur without the need for energy input.
A mondegreen is a mishearing or misinterpretation of a word or phrase, typically in a song or poem, in such a way that it results in a new meaning. The term was coined by Sylvia Wright in her 1954 essay, where she described how she misheard a line from a Scottish ballad: "They hung the wrong man." She interpreted it as "They eyed the wrong man.
Radiocarbon dating, also known as carbon-14 dating, is a scientific method used to determine the age of organic materials. It is based on the principle of radioactive decay of the isotope carbon-14 (^14C). Here's how it works: 1. **Formation of Carbon-14**: Carbon-14 is formed in the upper atmosphere when cosmic rays interact with nitrogen-14 (^14N).
Computer-Aided Simple Triage (CAST) is a system designed to assist emergency responders and medical personnel in rapidly assessing and prioritizing patients during mass casualty incidents or emergencies. The main goal of triage is to determine the severity of patients' conditions and allocate resources effectively based on their needs. CAST typically involves the use of software tools or applications that provide guidelines and algorithms for evaluating triage categories, such as: 1. **Immediate (Red)**: Patients who require immediate life-saving intervention.
Focal spot blooming is a phenomenon in imaging, particularly in radiography and fluoroscopy, that refers to the increase in the apparent size of the focal spot in the images produced. This effect can occur as a result of various factors, such as the quality of the X-ray equipment, the geometry of the beam, the energy levels used, and the characteristics of the detector or imaging system.
OceanX is an initiative that combines ocean exploration and advanced technology to enhance our understanding of the oceans and their ecosystems. It employs a high-tech research vessel, equipped with submersibles and advanced imaging tools, to explore, document, and study underwater environments, marine life, and geological formations. OceanX aims to promote marine conservation, raise awareness about ocean health, and inspire a connection between people and the sea through its explorations and educational endeavors.
Yuly Shokalsky was a prominent Russian and Soviet mathematician, renowned for his contributions to various areas of mathematics, particularly in geometry and topology. His work has had a significant impact on the field, and he is often recognized for his theoretical insights and research. Additionally, it’s worth noting that "Yuly Shokalsky" can also refer to a geographical feature or name in a specific context, such as a location or memorial.
Deepsea Challenger is a deep-diving submersible that was used to explore the Mariana Trench, the deepest part of the world's oceans. It was designed by filmmaker and explorer James Cameron and his team, and it made its historic dive on March 26, 2012. The submersible reached a depth of approximately 10,908 meters (35,787 feet) in the Challenger Deep, which is the deepest point in the Mariana Trench.
"Dutch cryptographers" likely refers to cryptographers from the Netherlands who have made significant contributions to the field of cryptography. Cryptography is the practice of securing communication and information through the use of codes and ciphers, and it plays a critical role in computer security, data protection, and secure communications.
Jaap Wessels is a Dutch academic known for his contributions to various fields, particularly in educational theory, technology integration in education, and research methodology. His work often revolves around innovative teaching practices, the use of technology in learning environments, and fostering critical thinking skills among students.

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
