The author shares their experience of creating a simple model of a planet using real geographical elevation data, inspired by the aesthetics of the game Outer Wilds. The project involves projecting Earth's elevation data onto a sphere, which is a complex task requiring triangulation. Instead, the author suggests generating sample points on the sphere and querying the elevation data for them, using resources from the Wolfram Language's standard library that includes a rough map of Earth and the capability to fetch higher-resolution data online. The process involves retrieving

The content discusses the FFaker library, a Ruby tool used for generating sample data in testing and development. It highlights its functionality, including various data types like names and credit card numbers, and notes that while the codebase is small, it features interesting elements such as metaprogramming and thread usage. The author focuses on the `FFaker::Name.first_name` and `FFaker::Name.unique.first_name` methods to explain their operation. Key points include that FFaker delays data loading until

The article discusses a new feature in Ruby 3.4 that allows developers to refer to the first parameter in a block without explicitly naming it. Starting from Ruby 2.7, numbered parameters could be used within blocks, but Ruby 3.4 enhances this functionality. It highlights the behavior of block parameters in nested blocks, where Ruby resolves the reference to the innermost block's parameter. In contrast, numbered parameters can cause ambiguities if there are methods or variables with the same name in

The author shares their experience teaching their daughter to ride a bike using a traditional method, which proved frustrating and ineffective. After some research, the author's wife discovered a more effective technique: removing the pedals from the bike initially. This allows the child to focus on balancing by straddling the bike and running forward, then coasting. As the child gains confidence and learns to balance, the pedals can be re-attached, making it easier for them to learn to pedal and ride confidently. This method emphasizes

The author reflects on their experience implementing Conway’s Game of Life using Rust, motivated by a desire to enhance their skills and nostalgia for the GameBoy Advance (GBA) from their childhood. Facing challenges in displaying simulation output and lacking web or desktop application development expertise, they turned to GBA development, particularly after the release of a new Rust crate for the platform. While outlining the basic concepts of Conway’s Game of Life, the author emphasizes the simplicity and complexity that arise from its 2D grid

The author shares an experience of encountering a challenging bug while using Microsoft Copilot for coding assistance in Python. The bug arose from an incorrect import statement using the "as" keyword, which allowed them to mistakenly import a Django test class with different semantics than intended. Specifically, they inadvertently imported `TestCase` instead of `TransactionTestCase`, leading to unexpected behavior in database transaction management during tests. The author highlights the consequences of this confusion and the importance of being cautious with naming conventions in imports to avoid

Many good programmers struggle with learning Rust and may even give up due to common mistakes. A key issue is a lack of focused learning; casually experimenting with Rust in short, scattered sessions is often ineffective. As learners encounter more complex concepts, they need to engage deeply to overcome challenges. Initial struggles are expected, but it's important to push through them, as proficiency will improve over time. To succeed, learners should familiarize themselves with Rust's core concepts, such as traits, macros, and smart pointers, preferably

The blog post discusses the complex and largely unexplored area of software sandboxing, highlighting the challenges of gathering comprehensive knowledge and best practices. The author shares personal experiences from working on sandboxing support for Emilua and offers an informal, yet practical, definition of sandboxing as the ability to restrict a process's privileges programmatically, without requiring administrative authority, and through discretionary privilege dropping. The post emphasizes the importance of clarity in understanding this definition and the author's evolving perspective on sandboxing practices, particularly regarding

Jon Sully discusses the upcoming changes to Heroku with the introduction of a new application stack codenamed "Fir." While Heroku has been a reliable platform-as-a-service (PaaS) for a decade, many are curious about the lack of significant updates during that time. The shift to Fir marks a notable change since the previous stack, Cedar, was launched in 2011. As of January 2025, Fir is in early beta for private spaces users, and detailed documentation is

The announcement introduces voyage-code-3, a new embedding model specifically designed for code retrieval, which outperforms both OpenAI-v3-large and CodeSage-large by averages of 13.80% and 16.81%, respectively, across 32 code retrieval datasets. This model reduces storage and search costs by utilizing lower-dimensional embeddings and quantized formats (int8 and binary) with minimal impact on retrieval quality, thanks to techniques like Matryoshka learning and quantization-aware training.
