The problem of missing people on the Internet
July 26, 2024 - Reading time: 8 minutes
If you are a frequent Internet user, you may notice an interesting phenomenon: a mismatch between your expectations of how many people should be engaged in various issues, and the actual reality. This situation is especially common on social media. For example, I recently joined a Facebook group with about 5 million members, but when I looked at the group's activity, I saw only about 10 people asking questions and making comments.
The same was true for Reddit. Conduct a test: go to Reddit and examine discussions in communities with over 200,000 members, where more than 50 members are online. You will hardly see any comments, and the ones you do see are often generic, like "Aha!" Recently, I tested this by posting a message in the group "MeaningOfLife," which has about 4k members. I was thrilled to receive one comment, but the group seemed completely inactive otherwise.
Next, visit Reddit's main page. You'll likely notice that 100% of the most popular posts are mundane, and honestly, quite silly, such as, "My girlfriend got a terrible haircut and she's crying," which garner thousands of comments and upvotes. While I suspect many of these comments and upvotes are from bots, it still raises questions. Why does this happen? Who (or what) is steering such discussions and with what purpose? Programmable bots? But who programmed them?

This world is not what it seems? And the Universe - is not your true home? Surely, you've experienced coincidences that can't be logically explained? Do you not understand the meaning of life? A new book called "The Designed World of Information: Unveiling the Incredible Realm Beyond" [book link] is something special.
How to create an article in the ZWI file format
February 19, 2024 - Reading time: 3 minutes
This short tutorial describes how to create an article in the ZWI file format developed for the Encyclosphere project. ZWI files with articles can be created either from existing articles in the HTML format, or writing a completely new article and then exporting it to the ZWI file format.
The Encyclosphere Is Greater than Wikipedia
August 1, 2023 - Reading time: 7 minutes
Wikipedia is just one encyclopedia, a ridiculously biased on. The collection of all the encyclopedias—that is what I mean by “the encyclosphere”—is more wide-ranging, fairer, and much larger. It contains sometimes surprising and, in 2023, delightful variety. Articles in other sources are frequently much more credible than those in Wikipedia. Limiting yourself to Wikipedia is like limiting yourself to just the mainstream media sources for your news. Why would you do that to yourself?
Top 5 Wikipedia alternatives you should know about in 2023
July 14, 2023 - Reading time: 4 minutes
In 2023 Wikipedia remains the world's biggest information resource used by communities of volunteers. Most of the other encyclopedic resources are smaller in size but, compared to Wikipedia, they are designed for specific areas of expertise and, typically, are maintained by non-for-profit organizations or persons with significant knowledge of specific topics. In many cases, they also have alternative publication policies for accepting online content, as well as the dispute resolution policies which have become increasingly important for the resources edited by large communities of experts.
Applications of CFD simulation in hydrogen fuel production

Hydrogen Storage Tank
Computational Fluid Dynamics (CFD) simulation can be applied in various aspects of hydrogen fuel production to optimize the design and operation of hydrogen production processes.
CFD can be used to simulate and analyze the fluid flow, heat transfer and chemical reactions occurring in different types of reactors used for hydrogen production, such as steam methane reformers (SMR), autothermal reformers (ATR) or solid oxide electrolysis cells (SOEC). By modeling the complex fluid dynamics and reaction kinetics, CFD helps in designing efficient reactors, optimizing operating conditions and improving overall process performance. It can aid in the design and analysis of hydrogen storage systems, such as high-pressure tanks or metal hydrides. It can help optimize the storage vessel geometry, assess the distribution of hydrogen within the storage system, analyze the release and dispersion of hydrogen during refueling or in case of accidental leaks.
