ApexKB is a knowledge base management system that enables organizations to create, manage, and share knowledge efficiently. It focuses on providing a centralized platform for documenting information, processes, best practices, and FAQs to improve internal communication and customer service. By utilizing features like search functionality, categorization, and user-friendly interfaces, ApexKB helps users find the information they need quickly. If you're looking for specific features or functionalities of ApexKB or have a particular context in mind (e.g.
Zettelkasten is a note-taking and knowledge management system developed by the German sociologist Niklas Luhmann in the 20th century. The name "Zettelkasten" translates to "slip box" in English, which reflects its original form: a physical box filled with index cards (or slips, known as "Zettel") containing short notes and ideas.
Staffing models refer to structured frameworks or methodologies that organizations use to determine their workforce needs, allocate resources, and manage human capital effectively. These models help in forecasting staffing requirements, optimizing employee roles, and ensuring that the right number of employees with the right skills are available to meet organizational goals. Key elements of staffing models include: 1. **Workforce Planning**: Assessing current staffing levels, predicting future needs based on factors like business growth, market trends, and turnover rates.
MIDI by Ciro Santilli 40 Updated 2025-07-16
In simple terms, represents keystrokes of a piano, but it can likely also represent other effects (TODO confirm: bend, vibrato, slides, attack strength)
Can contain multiple parallel tracks as seen from the Wikipedia example: en.wikipedia.org/wiki/File:MIDI_sample.mid
You can see what it contains well with GUI music editor.
MIDI is fun. It is a basic high level representation of most instrumental music, including beats.
To actually listen to MIDI, you need a software synthesizer, which knows what sound to make for each note. One way to specify such instruments is the SoundFont file format.

There are six, three in each sense, depending on where you start modulo-3.
The 3D structure of GFP is so cool. It is so clearly a bottle with a fluorescent bit well isolated right in the middle. Like a little lamp.
Axel Firsoff was a prominent figure in the field of astronomy, particularly known for his work in astrobiology and for advocating scientific literacy. He made contributions to the understanding of astrobiology, which studies the origin, evolution, distribution, and future of life in the universe.
Wendy Taylor is a physicist known for her work in various fields, including laser physics and optical engineering. However, detailed information and specifics about her accomplishments may not be widely available in public literature.
Leon Barritt does not appear to be a widely recognized figure in publicly available information up to October 2023. It’s possible that he could be a private individual, a local personality, or someone relevant in a specific context not covered in general knowledge.
As of my last knowledge update in October 2023, there is no widely recognized individual or concept known as "Paul Baize." It is possible that you may be referring to a less well-known figure, a character in a specific work, or a term that has emerged after my last update.
David D. Balam is a prominent figure in the field of astronomy and a professor at the University of Hawaii. He is known for his research and contributions to the study of celestial objects and phenomena, particularly in the context of asteroids and distant galaxies. His work often involves observational studies and the analysis of astronomical data. If you meant something else or if David D. Balam has a specific context, please provide more details!
Cathy Drennan is a prominent biochemist known for her research in the fields of enzymology, structural biology, and biophysics. She has made significant contributions to the understanding of metalloproteins and their roles in biological processes, particularly focusing on how metal ions are utilized by enzymes. Drennan is a professor and has held positions at various institutions, including the Massachusetts Institute of Technology (MIT).
William Barlow is a notable figure in the field of geology, particularly known for his contributions to the study of coal geology and the understanding of geological formations.

Gerhard Ertl is a German physicist and chemist known for his pioneering work in the field of surface chemistry. He was awarded the Nobel Prize in Chemistry in 2007 for his research on chemical processes at surfaces, which has significant implications for catalysis and materials science. Ertl's work has contributed to a deeper understanding of how reactions take place on solid surfaces, and his findings have applications in various industries, including energy and materials technology.

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
