tx 210000d1392bec2505d1289e5c39c2039204ff1ecf7eef55f973ccd3111003e1, block 360235 (2015-06-10) and the following transactions have transcripts of a very long developer chat starting with:
TODO purpose? The transcripts are interspersed with developers likely voting for project leadership, and commenting on Gavin.
TODO find original discussion location, these are almost certainly from one of the Bitcoin IRC channels.
Part of the goal of this dump is that the Bitcoin developers have a policy of not allowing logging on their talk channel, and this released it all to the blockchain forever where it cannot be deleted. These might just be more of protests against larger block sizes.
The Neumann–Dirichlet method refers to a numerical technique used to solve partial differential equations (PDEs), particularly in the context of fluid dynamics, electrostatics, and other fields where boundary value problems arise. The method involves a combination of the Dirichlet boundary condition, where the solution is specified on a boundary, and the Neumann boundary condition, where the derivative (often representing a flux or gradient) of the solution is specified on a boundary.
"BUNCH" can refer to a few different things depending on the context. Here are a few possible meanings: 1. **General Term**: In a general context, "bunch" refers to a collection or group of items, often grouped together in a loose or informal manner. For example, a bunch of grapes or a bunch of flowers. 2. **Acronym**: BUNCH could be an acronym in various fields.
The Photon Epoch refers to a specific period in the early universe, approximately from 10 seconds to about 380,000 years after the Big Bang. During this epoch, the universe was filled with a hot, dense plasma composed mostly of photons, electrons, protons, and other particles. The temperatures were extremely high, and matter existed in a highly energetic state.
Numerical resistivity typically refers to a method used in geophysical and geological studies to interpret subsurface resistivity measurements. Resistivity is a measure of how strongly a material opposes the flow of electric current, and it is often used in applications such as environmental monitoring, mineral exploration, and hydrogeology. In practice, numerical resistivity involves using mathematical and computational models to analyze resistivity data collected through techniques like Electrical Resistivity Tomography (ERT) or Induced Polarization (IP).
The "parallel parking problem" is a well-known problem in the fields of robotics and computer science, particularly in the area of motion planning and autonomous vehicle navigation. It involves the challenge of maneuvering a vehicle into a parallel parking space, which typically involves reversing into a nook between two parked cars with limited space. ### Key Concepts: 1. **Movement Dynamics**: The vehicle must be able to navigate turnings and adjust its position based on its size and the size of the parking space.
To Peter D. Mitchell for the discovery of the mechanism of ATP synthesis in the mitochondria, a central part of cellular respiration.
The patch test is a numerical verification method used in the finite element method (FEM) to assess the accuracy and convergence properties of finite element formulations. It is primarily applied to ensure that a finite element method is capable of accurately representing certain types of exact solutions, particularly those that are polynomial in nature. ### Purpose of the Patch Test 1. **Verification of Element Formulation**: The patch test helps verify whether the finite element formulation can reproduce constant and linear solutions within a specified domain.
The Pearcey integral is a special function that arises in the study of problems in optics and wave propagation, particularly in the context of diffraction patterns. It is associated with diffraction phenomena and is particularly relevant to situations involving oscillatory integrals.
"CPU Wars" typically refers to the competitive landscape between major microprocessor manufacturers, most notably Intel and AMD. It highlights the ongoing rivalry in developing and releasing advanced CPUs (central processing units) for personal computers, servers, and other computing devices. Over the years, both Intel and AMD have engaged in a series of technological battles, often leading to significant advancements in processing power, efficiency, and pricing strategies for consumers.

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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.Figure 1. Screenshot of the "Derivative" topic page.

Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
