Buddhism by Ciro Santilli 40 Updated 2025-07-16
Ciro Santilli's favorite religion. He does not believe fully in it, nor has he studied it besides through brief Wikipedia and Googling.
Ciro likes Buddhism because it feels like the least "metaphysical explanations to things you can't see" of the religions he knows.
Rather, it feels more like "a plausible theory of the mind" and highly compatible with physics.
Ciro also believes that there is a positive correlation between being a software engineer and liking Buddhist-like things, see also: the correlation between software engineers and Buddhism.
Optical microscope by Ciro Santilli 40 Updated 2025-07-16
Definition not very nice, as it excludes X-ray crystallography, which is also photon based.

PostgreSQL logging by Ciro Santilli 40 Updated 2025-07-16
Ubuntu 21.10 has a certain default level of logging by default to:
/var/log/postgresql/postgresql-13-main.log
but it does not log everything, only/mostly errors it seems.
Setting:
log_statement = 'all'
under:
/etc/postgresql/13/main/postgresql.conf
and then restarting the server:
sudo service restart postgresql
just works.
As of 2022, this channel is still finding its feet. But it has promise.
Unfortunately it does not show sample preparation, and it does not use controlled cultures, so we are never sure which species are represented.
"Paul Silver" could refer to a number of things depending on the context, as it's not a widely recognized term or figure. It might refer to a person's name, possibly someone in a specific field such as business, art, or entertainment. If you're thinking of a specific Paul Silver, providing more context would help narrow it down to the right reference. Alternatively, it could also be a brand, company, or concept.
Identity fusion is a psychological concept that refers to a strong, personal connection between an individual and a group, leading to a sense of oneness or unity with that group. This phenomenon goes beyond mere social identification, where individuals recognize themselves as members of a groupidentity fusion involves a deep emotional bond that can significantly influence behavior and decision-making.
Linear motion refers to the motion of an object along a straight path. It can be described in terms of displacement, velocity, acceleration, and time. In linear motion, the position of an object changes in a straight line and can be characterized by the following key concepts: 1. **Displacement**: The shortest distance from the initial position to the final position of the object, which includes the direction of the movement.
The Treaty of Zaragoza, signed on April 22, 1529, was an agreement between Spain and Portugal that established a maritime boundary between the two nations in the Spice Islands, also known as the Moluccas. This treaty was a follow-up to the Treaty of Tordesillas, which had previously divided the newly discovered lands outside Europe between Spain and Portugal.
Georg Gottlob is a prominent computer scientist known for his contributions to theoretical computer science, particularly in the areas of logic programming, query languages, and database theory. He is recognized for his work on the foundations of knowledge representation and reasoning, as well as for developing algorithms and techniques related to efficient query processing and optimization in databases.
Model-Based Definition (MBD) is a method used in engineering and manufacturing where product information, including geometry, dimensions, and tolerances, is contained within a 3D model rather than in traditional 2D drawings. MBD leverages 3D Computer-Aided Design (CAD) models to convey all necessary information for manufacturing and quality control processes.
Yevgeny Dyakonov is a Russian scientist known for his work in the field of theoretical physics, particularly in areas related to condensed matter physics and electromagnetism. He is recognized for contributions to the study of electromagnetic phenomena, spintronics, and related materials.
Lance Hoffman is a computer scientist and professor known for his work in the fields of cybersecurity, computer security, and privacy. He has been involved in academic research and has contributed to discussions on various topics related to information security. He may also be recognized for his involvement with organizations and institutions focusing on technology and its implications for society.
Los Alamos chess is a variant of chess that was invented in the 1970s by a group of chess enthusiasts in Los Alamos, New Mexico. This variant is played on a standard chessboard with the regular pieces, but it introduces some unique rules that differentiate it from traditional chess. In Los Alamos chess, each player has the ability to move a piece and then "block" the opponent's piece with a different piece on the next turn, adding a strategic layer to the game.
Hal Abelson is a prominent computer scientist and educator, known for his contributions to computer science education, programming languages, and the development of the field of artificial intelligence. He is a professor of electrical engineering and computer science at MIT (Massachusetts Institute of Technology) and has co-authored several influential textbooks, including “Structure and Interpretation of Computer Programs” (SICP), which is widely used in computer science curricula.
Mark Pesce is an Australian author, entrepreneur, and futurist known for his work in technology, particularly in relation to the internet and digital media. He has been influential in the development of various tech concepts and has written extensively on topics like virtual reality, augmented reality, and the implications of emerging technologies on society.

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
