Hi everyone,

I'm baaaaack!

I co-founded Wikipedia long ago. While I was gone for a long time, I did keep abreast what's been going on and how the system works, as a student and critic of Wikipedia and of the internet generally.

But as of fall 2025, I have returned, with the aim of helping Wikipedia in various ways to reform.

Most recently, I have been working on WikiProject Intellectual Diversity. This is not yet an approved WikiProject, but I am confident we will get enough supporters to make our application successful. If you too want Wikipedia to be reformed in ways that will make the project more open and welcoming to those of a more intellectually diverse body of contributors, please join!

For most of 2025, I developed Nine Theses on Wikipedia, which is partly an extended criticism and partly a reform proposal. Unlike much of my previous writing and speaking about Wikipedia over the past 20 years or so, this is not merely negative. It is a realistic plan to make Wikipedia better. I hope you will take it seriously.

All the best,

P.S. Here's what I posted when I left in 2002. Still good advice:

All the best to Wikipedia and Wikipedians. May you continue

• to be open and warmly welcoming, not insular,
• to be focused singlemindedly on writing an encyclopedia, not on Usenet-style debate,
• to recognize and praise the best work, work that is detailed, factual, well-informed, and well-referenced,
• to work to understand what neutrality requires and why it is so essential to and good for this project,

• to treat your fellow productive, well-meaning members of Wikipedia with respect and good will,
• to attract and honor good people who know a lot and can write about it well, and
• to show the door to trolls, vandals, and wiki-anarchists, who if permitted would waste your time and create a poisonous atmosphere here.

Muḥammad ibn Mūsā al-Khwārizmī (Persian: Muḥammad Khwārizmī محمد بن موسی خوارزمی‎; c. 780 – c. 850), Arabized as al-Khwarizmi with al- and formerly Latinized as Algorithmi, was a Persian polymath who produced works in mathematics, astronomy, and geography. Around 820 CE he was appointed as the astronomer and head of the library of the House of Wisdom in Baghdad.

Al-Khwarizmi's popularizing treatise on algebra (The Compendious Book on Calculation by Completion and Balancing, c. 813–833 CE) presented the first systematic solution of linear and quadratic equations. One of his principal achievements in algebra was his demonstration of how to solve quadratic equations by completing the square, for which he provided geometric justifications. Because he was the first to treat algebra as an independent discipline and introduced the methods of "reduction" and "balancing" (the transposition of subtracted terms to the other side of an equation, that is, the cancellation of like terms on opposite sides of the equation), he has been described as the father or founder of algebra. The term algebra itself comes from the title of his book (specifically the word al-jabr meaning "completion" or "rejoining"). His name gave rise to the terms algorism and algorithm. His name is also the origin of (Spanish) guarismo and of (Portuguese) algarismo, both meaning digit.

In the 12th century, Latin translations of his textbook on arithmetic (Algorithmo de Numero Indorum) which codified the various Indian numerals, introduced the decimal positional number system to the Western world. The Compendious Book on Calculation by Completion and Balancing, translated into Latin by Robert of Chester in 1145, was used until the sixteenth century as the principal mathematical text-book of European universities.

In addition to his best-known works, he revised Ptolemy's Geography, listing the longitudes and latitudes of various cities and localities. He further produced a set of astronomical tables and wrote about calendaric works, as well as the astrolabe and the sundial. He also made important contributions to trigonometry, producing accurate sine and cosine tables, and the first table of tangents.

🔗 Philosophy 🔗 Philosophy/Logic 🔗 Philosophy/Contemporary philosophy 🔗 Philosophy/Philosophy of mind 🔗 Philosophy/Analytic philosophy

The Chinese room argument holds that a digital computer executing a program cannot be shown to have a "mind", "understanding" or "consciousness", regardless of how intelligently or human-like the program may make the computer behave. The argument was first presented by philosopher John Searle in his paper, "Minds, Brains, and Programs", published in Behavioral and Brain Sciences in 1980. It has been widely discussed in the years since. The centerpiece of the argument is a thought experiment known as the Chinese room.

The argument is directed against the philosophical positions of functionalism and computationalism, which hold that the mind may be viewed as an information-processing system operating on formal symbols. Specifically, the argument is intended to refute a position Searle calls strong AI: "The appropriately programmed computer with the right inputs and outputs would thereby have a mind in exactly the same sense human beings have minds."

Although it was originally presented in reaction to the statements of artificial intelligence (AI) researchers, it is not an argument against the behavioural goals of AI research, because it does not limit the amount of intelligence a machine can display. The argument applies only to digital computers running programs and does not apply to machines in general.

🔗 Internet 🔗 Hong Kong

Hong Kong Internet eXchange (HKIX; Chinese: 香港互聯網交換中心) is an internet exchange point in Hong Kong. The cooperative project is initiated by the Information Technology Services Centre (ITSC) of the Chinese University of Hong Kong (CUHK) providing the service free of charge. It is now operated by HKIX Limited, a wholly owned subsidiary of the CUHK Foundation.

The aim of the HKIX is to connect Internet service providers (ISPs) in Hong Kong so that intra-Hong Kong traffic can be exchanged locally without routing through the US or other countries. 99% internet interaction in Hong Kong goes through the centre, and HKIX acts as Hong Kong's network backbone. According to Cloudflare, HKIX is the largest internet exchange point in Asia.

🔗 Computing 🔗 Computing/Software

Delphi is an event-driven programming language based on Object Pascal and an associated integrated development environment (IDE) for rapid application development of desktop, mobile, web, and console software, currently developed and maintained by Embarcadero Technologies.

Delphi's compilers generate native code for Microsoft Windows, macOS, iOS, Android and Linux (x64 only). Since 2016, there have been new releases of Delphi every six months, with new platforms being added approximately every second release.

Delphi includes a code editor, a visual designer, an integrated debugger, a source code control component, and support for third-party plugins. The code editor features Code Insight (code completion), Error Insight (real-time error-checking), and refactoring. The visual forms designer has traditionally used Visual Component Library (VCL) for native Windows development, but the FireMonkey (FMX) platform was later added for cross-platform development. Database support in Delphi is very strong. A Delphi project of a million lines of code can compile in a few seconds – one benchmark compiled 170,000 lines per second.

Delphi was originally developed by Borland as a rapid application development tool for Windows as the successor of Turbo Pascal. Delphi added full object-oriented programming to the existing language, and since then the language has grown to support generics and anonymous methods, and native Component Object Model (COM) support. In 2006, Borland’s developer tools section was transferred from Borland to a wholly owned subsidiary known as CodeGear, which was sold to Embarcadero Technologies in 2008. In 2015, Embarcadero was purchased by Idera Software, but the Embarcadero mark was retained for the developer tools division.

Delphi and its C++ counterpart, C++Builder, are interoperable. They share many core components, notably the IDE, VCL, and much of the runtime library. In addition, they can be used jointly in a project. For example, C++Builder 6 and later can consume Delphi source code and C++ in one project, while packages compiled with C++Builder can be used from within Delphi. In 2007, the products were released jointly as RAD Studio, a shared host for Delphi and C++Builder, which can be purchased with either or both.

Jimmy Carter, United States president from 1977 until 1981, reported seeing an unidentified flying object while at Leary, Georgia, in 1969. While serving as governor of Georgia, Carter was asked (on September 14, 1973) by the International UFO Bureau in Oklahoma City to file a report of the sighting, and he filed a statement on September 18, mailed September 20. Since its writing, the report has been discussed several times by both ufologists and by members of the mainstream media.

🔗 Computing 🔗 Computing/Computer hardware

Model M designates a group of computer keyboards designed and manufactured by IBM starting in 1984, and later by Lexmark International, Maxi Switch, and Unicomp. The keyboard's many variations have their own distinct characteristics, with the vast majority having a buckling-spring key design and swappable keycaps. Model M keyboards have been praised by computer enthusiasts and frequent typists due to their durability and consistency, and the tactile and auditory feedback they provide.

The Model M is also regarded as a timeless and durable piece of hardware. Although the computers and computer peripherals produced concurrently with the Model M are considered obsolete, many Model M keyboards are still in use due to their physical durability and the continued validity of their ANSI 101-key and ISO 102-key layouts, through the use of a PS/2 female to USB male adapter with a built-in level converter. Since their original popularity, new generations of writers and computer technicians have rediscovered their unique functionality and aesthetics. The Kentucky-based company Unicomp continues to manufacture and sell Model M keyboards.

The Five Eyes (FVEY) is an anglophone intelligence alliance comprising Australia, Canada, New Zealand, the United Kingdom and the United States. These countries are parties to the multilateral UKUSA Agreement, a treaty for joint cooperation in signals intelligence.

The origins of the FVEY can be traced back to the post–World War II period, when the Atlantic Charter was issued by the Allies to lay out their goals for a post-war world. During the course of the Cold War, the ECHELON surveillance system was initially developed by the FVEY to monitor the communications of the former Soviet Union and the Eastern Bloc, although it is now used to monitor billions of private communications worldwide.

In the late 1990s, the existence of ECHELON was disclosed to the public, triggering a major debate in the European Parliament and, to a lesser extent, the United States Congress. As part of efforts in the ongoing War on Terror since 2001, the FVEY further expanded their surveillance capabilities, with much emphasis placed on monitoring the World Wide Web. The former NSA contractor Edward Snowden described the Five Eyes as a "supra-national intelligence organisation that does not answer to the known laws of its own countries". Documents leaked by Snowden in 2013 revealed that the FVEY has been spying on one another's citizens and sharing the collected information with each other in order to circumvent restrictive domestic regulations on surveillance of citizens.

In spite of continued controversy over its methods, the Five Eyes relationship remains one of the most comprehensive known espionage alliances in history.

Since processed intelligence is gathered from multiple sources, the intelligence shared is not restricted to signals intelligence (SIGINT) and often involves defence intelligence as well as human intelligence (HUMINT) and geospatial intelligence (GEOINT). The following table provides an overview of most of the FVEY agencies involved in such forms of data sharing.
