4. Blurry rendering of games on Mac
Total comment counts : 33
Summary
A reported issue (FB13375033) with MacBook displays affects game rendering, particularly for full-screen applications built in AppKit or Catalyst. Many games mistakenly choose the full screen resolution, which includes the area above the notch, resulting in distorted visuals. The CGDisplayCopyAllDisplayModes function provides mixed resolutions that can lead to this problem. Developers can address this by filtering resolutions based on the safe area, but challenges remain in identifying optimal resolutions. Users should select 16:10 resolutions for the best experience on notched displays, as many games default to incorrect settings.
Top 1 Comment Summary
The author expresses frustration with modern screens featuring rounded corners and notches, questioning their aesthetic value. They contrast this with the struggles of using CRT displays with imperfect geometry, lamenting that after achieving perfect screen designs, we now compromise them for style over functionality.
Top 2 Comment Summary
The article discusses an option in World of Warcraft (WoW) that allows the user interface (UI) to avoid the screen notch.

6. Why LLMs can’t really build software
Total comment counts : 70
Summary
The article discusses the importance of clear mental models in effective software engineering, contrasting human engineers with large language models (LLMs). While LLMs can generate and update code, they struggle to maintain clarity when faced with complexities, often leading to confusion and unsuccessful problem-solving. Human engineers, conversely, utilize mental models to navigate challenges, make informed decisions, and seek help when needed. Although LLMs are valuable tools for coding and documentation, they currently lack the capability to handle non-trivial issues, leaving software engineers responsible for clarity and accuracy in their work.
Top 1 Comment Summary
The article emphasizes the importance of understanding the root cause of software problems rather than hastily implementing quick fixes. It illustrates this by discussing an authentication error, demonstrating that it often stems from deeper issues, like an incorrect test rather than the token check itself. Effective problem-solving requires software engineers to analyze the situation comprehensively, ensuring clear differentiation in error responses and improving overall software quality.
Top 2 Comment Summary
The author critiques the misunderstanding of LLMs and coding tools, highlighting that they often assume their generated code functions correctly and struggle when tests fail, leading to confusion and unnecessary restarts. In contrast, experienced software engineers employ a mental model to decide whether to fix code or tests. The author shares a positive experience using Cline with Anthropic Sonnet 3.7 for test-driven development, noting that the model effectively writes tests first, reasons about failures, and learns from additional code, performing comparably to a junior engineer, despite some limitations.
7. We rewrote the Ghostty GTK application
Total comment counts : 20
Summary
The Ghostty GTK application has been fully rewritten to integrate the GObject type system from Zig, enhancing stability, features, and maintainability on Linux and BSD. This process involved verifying the application with Valgrind, addressing memory issues, and facilitating better memory management. By wrapping the Zig-owned Config structure in a reference-counted GObject, configuration reloading became simpler and more efficient. The rewrite also enabled the use of modern GTK GUI features, resulting in easier implementation of new functionalities. Valgrind identified only one leak and one undefined memory access in the Zig codebase, which was surprisingly low given its complexity.
Top 1 Comment Summary
The author discusses the challenges of creating Godot bindings in Zig, highlighting the complexity of integrating Object-Oriented Programming concepts like classes and properties with Zig’s idioms, particularly regarding object lifetimes. They have made progress but seek further insights or code snippets. They mention their library, which they’re not proud of, and share a link to a specific API example. Additionally, they express interest in developing a Ghostty frontend as a Godot extension.
Top 2 Comment Summary
The article discusses the challenges of programming with GTK and the GObject type system, emphasizing that developers must interface with it despite personal preferences towards OOP and memory management. Avoiding GObject leads to difficulties in managing the lifetimes of objects, resulting in bugs in the Ghostty GTK application, particularly when either Zig or GTK memory is freed without coordinating both.

10. What’s the strongest AI model you can train on a laptop in five minutes?
Total comment counts : 53
Summary
The strongest model trainable on a MacBook Pro in five minutes is a ~1.8 million parameter GPT-style transformer using ~20 million TinyStories tokens, achieving a perplexity of ~9.6. The author notes that while this model isn’t exceptional, it’s commendable for the limited training time. He explores training challenges, emphasizing the importance of model size, dataset quality, and training speed optimizations. Key recommendations include using Apple’s MPS, avoiding gradient accumulation, and selecting smaller models. The author highlights the challenges of dataset representation when limited to around 10 million tokens.
Top 1 Comment Summary
Optimized small model training is crucial for both accessibility and the scientific understanding of large language models (LLMs). Similar to using simple organisms like yeast for biological research, studying minimal transformers that demonstrate key behaviors of larger models is essential for comprehending LLMs and gaining greater control over their functions.
