Toronto's Path: A Spontaneously Formed Pedestrian Subway Network

Toronto's congested downtown spurred businesses to create a network of underground tunnels connecting offices to subway stations – "The Path." Over decades, this 30km+ system, independently managed by numerous owners, alleviated surface congestion and evolved into a thriving shopping mall. This unique case study in urban transportation planning raises the question: why hasn't a similar 'pedestrian metro' model been widely replicated in other cities?

The Thermocline of Truth in IT Projects

2025-09-02

This article explores the 'thermocline of truth' phenomenon in large IT projects: a barrier to accurate information within the organizational structure, where lower-level employees know the real progress while upper management holds an overly optimistic view. This stems from a lack of objective metrics, engineers' optimism, managers' reluctance to deliver bad news, and upper management rewarding good news and punishing bad news. The author uses personal anecdotes and real-world examples to illustrate this, emphasizing that breaking the 'thermocline' requires honesty from below, rewarding honesty from above, and avoiding unrealistic project timelines.

Next.js Logging Nightmare: A Struggle with Production Logging

The author encountered a series of challenges while attempting to add production logging to a Next.js service. Next.js's middleware mechanism is heavily restricted, and AsyncLocalStorage couldn't bridge the rendering context, resulting in logging failures in pages and layout components. The author tried various methods, including a custom server, ultimately discovering that Next.js's design limited the implementation of logging features. A comparison with SvelteKit highlights Next.js's shortcomings in logging and the inefficiency of its GitHub issue tracker. The author expresses dissatisfaction with Next.js and considers alternatives for future projects.

LLMs: Lossy Encyclopedias

2025-09-02

Large language models (LLMs) are like lossy encyclopedias; they contain a vast amount of information, but this information is compressed, leading to data loss. The key is discerning which questions LLMs can answer effectively versus those where the lossiness significantly impacts accuracy. For example, asking an LLM to create a Zephyr project skeleton with specific configurations is a 'lossless' question requiring precise details, which LLMs struggle with. The solution is to provide a correct example, allowing the LLM to operate on existing facts rather than relying on potentially missing details within its knowledge base.

Indices, Not Pointers: A Zig Performance Trick

2025-09-03

A novel approach in Zig uses indices instead of pointers in data structures, resulting in significant performance gains. By storing nodes in a dynamic array and referencing them via indices, this technique reduces memory allocation overhead, lowers memory usage, speeds up access times, and makes freeing instantaneous. This is particularly beneficial for node-based structures like trees, and is used in Zig's compiler for efficient ASTs. While removing individual nodes requires additional handling (e.g., a freelist), the overall performance boost is substantial.

The latest Steam Hardware Survey reveals that 32GB of RAM is poised to become the most popular configuration among Steam gamers, potentially surpassing 16GB by the end of 2025. While the RTX 5060 outperforms the RTX 4060 in new PC sales, the RTX 4060 maintains a significant presence in the Steam survey, possibly due to remaining stock in certain regions or continued sales of pre-built systems. Additionally, the 2560 x 1600 pixel resolution is experiencing the fastest growth, and Windows 11 has exceeded 60% market share.

Triangular Grids: A Fresh Perspective on Tactical Game Design

2025-09-03

Square and hexagonal grids are commonplace in strategy games, but triangular grids remain largely unexplored. This article delves into the advantages of triangular grids in game design, highlighting their visual flexibility in representing both straight lines and curves, and their unique tactical possibilities. Unlike square grids with 4 directions and hexagonal grids with 6, triangular grids, when allowing diagonal movement, offer up to 12 directions, significantly increasing tactical options. The article details coordinate representation, conversion methods, and various distance calculation formulas for triangular grids, providing a small open-source library for developers. While few games currently utilize triangular grids, their potential is vast, promising a fresh take on strategy game mechanics.

Dissecting the Apple Silicon Mac Boot Process: From Boot ROM to Userspace

This article delves into the boot process of an Apple Silicon Mac. Starting from the Boot ROM, it traces the sequence through the Low-Level Bootloader (LLB) and iBoot, kernel startup, system clock adjustments, and finally, the unlocking of the data volume to enter userspace. Using a Mac mini M4 Pro log as an example, the article details each phase, highlighting the lower log frequency and kernel-centric entries before data volume unlock, contrasting with the significantly higher frequency and reduced kernel contribution afterwards. This process reveals insights into Apple Silicon Mac's security mechanisms and boot efficiency.

The Century-Long Keyboard War: QWERTY vs. Dvorak

This essay delves into the century-long history of the QWERTY and Dvorak keyboard layouts. QWERTY, far from being random, was ingeniously designed to solve mechanical limitations in early typewriters. Dvorak, conversely, aimed for efficiency and ergonomics. Despite Dvorak's demonstrated advantages in trials, historical factors like market inertia, switching costs, and a lack of sustained marketing prevented its widespread adoption. The article reveals the intricate interplay of technological progress, market forces, and human biases in shaping keyboard layouts, prompting reflection on technology standard selection and market competition.

World Models: The Illusion and Reality of AGI

World Models: The Illusion and Reality of AGI

The latest pursuit in AI research, especially in AGI labs, is the creation of a "world model" – a simplified representation of the environment within an AI system, like a computational snow globe. Leading figures like Yann LeCun, Demis Hassabis, and Yoshua Bengio believe world models are crucial for truly intelligent, scientific, and safe AI. However, the specifics of world models are debated: are they innate or learned? How do we detect their presence? The article traces the concept's history, revealing that current generative AI may rely not on complete world models, but on numerous disconnected heuristics. While effective for specific tasks, these lack robustness. Building complete world models remains crucial, promising solutions to AI hallucinations, improved reasoning, and greater interpretability, ultimately driving progress towards AGI.

The Demise of 32-bit Support in the Linux Kernel?

2025-09-02

At the Open Source Summit Europe 2025, Arnd Bergmann, the maintainer of architecture support in the Linux kernel, delivered a talk discussing the potential removal of 32-bit system support. While desktop and server systems have long transitioned to 64-bit, a significant number of 32-bit devices remain in embedded systems. Bergmann noted that while the kernel is still adding support for some 32-bit boards, the number of 64-bit boards supported has significantly surpassed 32-bit ones. He argued that removing 32-bit support is a gradual process, requiring consideration of existing hardware and software support and analyzing user numbers to determine when to remove support for specific architectures. The talk also addressed challenges and solutions related to 32-bit support, such as high-memory support, the year-2038 problem, and big-endian support. Ultimately, Bergmann stated that the kernel will retain support for armv7 systems for at least another ten years, while support for other 32-bit architectures will likely fade away sooner.
