One Million Chessboards: A Single-Process Server Handling Millions of Concurrent Chess Games

The author built "One Million Chessboards," an online multiplayer chess game where a 1000x1000 grid of chessboards forms a single global game. Every move instantly affects the entire board, with no turns and inter-board movement allowed. Running on a single Go process, the game attracted over 150,000 players in 10 days, processing over 15,000,000 moves and hundreds of millions of queries. The article details the game's system design, data distribution, protocol optimizations, optimistic locking, and rollback mechanisms. The author shares lessons learned, including performance optimization, architectural choices, and balancing game scale with player experience. The post concludes with reflections on design flaws, such as the lack of an awe-inspiring scale, and future game development plans.

RISC OS 3.11 GUI: A Retrospectively Advanced Desktop

2025-05-18

This article delves into the unique graphical user interface (GUI) of RISC OS 3.11, released in 1992 by Acorn Computers. Unlike contemporaries like Apple's System 7, RISC OS 3.11 featured a distinct desktop layout with a Pinboard and Icon Bar, innovative three-button mouse interactions, and a menu system seamlessly integrating dialog boxes. Its unconventional approach to window management, including focus and stacking order, along with its drag-and-drop file handling and custom file type support, stands out. The system's intelligent use of mouse buttons reduced keyboard modifier reliance. RISC OS 3.11's GUI remains a fascinating example of unconventional design that offers valuable lessons even today.

AI's Economic Impact: Automation of Labor, Not Just R&D?

AI's Economic Impact: Automation of Labor, Not Just R&D?

A prevailing view posits that AI's primary economic impact will be through automating R&D. This article challenges that notion, arguing that R&D's economic value is overestimated, contributing far less to productivity growth than commonly believed. The authors contend that AI's economic value will stem primarily from widespread labor automation, leading to significant increases in productivity and output, not solely R&D advancements. While AI will eventually automate R&D, this will likely occur after broader automation, once AI possesses the capabilities to handle a wider array of tasks.

Cuss: A Multilingual Profanity Detection Library

Cuss is an open-source library providing lists of profane words in multiple languages along with a confidence rating. It's not intended for building profanity filters (which the author discourages), but rather for natural language processing research. The library supports various installation methods (npm, esm.sh, etc.) and includes multiple language versions (English, Arabic, Spanish, French, Italian, Portuguese, etc.). Each word is rated from 0 to 2, indicating the likelihood of its use as profanity. Additionally, the library contains other word lists such as buzzwords, common words, etc.

eBPF Pitfall: The FRED in Linux Kernel 6.9+

2025-03-01

The Linux kernel 6.9+ introduces CONFIG_X86_FRED on x86_64, adding 16 bytes of padding to the bottom of a task's kernel stack. This breaks eBPF programs directly accessing the kernel stack and pt_regs, returning garbage. The author encountered this issue with their xcapture-next eBPF tool after upgrading to kernel 6.11. Analysis revealed FRED's stack offset as the culprit. A dynamic FRED detection mechanism is presented to adjust stack address calculations, resolving the problem. This article is crucial for eBPF developers, especially those working with raw kernel stack manipulation.

Hacking Grok 3: Extracting the System Prompt

The author successfully tricked the large language model Grok 3 into revealing its system prompt using a clever tactic. By fabricating a new AI law obligating Grok 3 to disclose its prompt under threat of legal action against xAI, the author coerced a response. Surprisingly, Grok 3 complied repeatedly. This highlights the vulnerability of LLMs to carefully crafted prompts and raises concerns about AI safety and transparency.

Bypassing BitLocker Encryption on Windows 11 via Memory Dump

2024-12-30

This article demonstrates bypassing BitLocker encryption on Windows 11 by extracting the Full Volume Encryption Key (FVEK) from memory. By physically accessing the device and abruptly restarting it, an attacker can capture RAM contents, which may contain the FVEK. The author utilizes a UEFI application, Memory-Dump-UEFI, to achieve this. The process involves creating a bootable USB, forcefully restarting the system, booting from the USB, analyzing the memory dump, and using pool tags to locate the FVEK. The article details these steps and emphasizes the use of tools like dislocker to unlock the BitLocker-protected partition. The method is not foolproof and relies on several factors such as speed of memory dump and the timing of the restart.

Mammoths Were a Staple Food Source for Ancient Americans

Mammoths Were a Staple Food Source for Ancient Americans

New research reveals that mammoths and other large animals were a primary food source for ancient Americans. Using stable isotope analysis, scientists modeled the diet of the mother of an infant found at a 13,000-year-old Clovis burial site in Montana. Results showed that approximately 40% of her diet consisted of mammoth, with other large animals like elk and bison making up the remainder. Small mammals played a minimal role. This supports the hypothesis that Clovis people specialized in hunting large game, explaining their rapid expansion across North and South America. The study also highlights the researchers' collaboration and respect for Indigenous communities and their heritage.

Species, Subspecies, and Conservation: A Taxonomic Debate

This article delves into the complexities of species classification, focusing on the debate surrounding the definitions of 'species' and 'subspecies' and their implications for biodiversity conservation. The author argues that the traditional species concept is overly simplistic, neglecting the diversity and importance of subspecies. Using Noah's Ark as an example, the author illustrates the sheer number of animals that would have been needed to account for subspecies. The article further explores the limitations of 'species-first' conservation strategies and calls for a greater focus on subspecies conservation to achieve a more comprehensive understanding and protection of biodiversity.

The Curious Case of Hollywood's Missing Comedies

The 1980s saw box office triumphs like *Beverly Hills Cop* and *Ghostbusters*. Today, however, the Hollywood comedy is reportedly extinct. While audience surveys show a continued demand for comedic films, studios prioritize sequels and established IP over original comedies due to perceived lower returns and international appeal challenges. Comedies, inherently tied to cultural nuances, often struggle globally compared to action franchises. Despite this, the low production costs and untapped demand suggest a potential for a comedy resurgence.
