Good error handling is essential for creating robust programs, yet it often frustrates programmers due to the challenge of accounting for every edge case. Traditional object-oriented languages use exceptions for immediate error reporting by breaking the regular control flow. In contrast, newer languages like Go and Rust employ functional-style error handling, encoding errors in return types (e.g., Go uses (res, err) tuples, and Rust uses Result<T, E>). While these approaches aim to make error handling more explicit and encourage programmers to consider

In May, the Chrome team officially replaced First Input Delay (FID) with Interaction to Next Paint (INP) as the Core Web Vitals metric for measuring interaction responsiveness. This follows an announcement in January about phasing out FID. As of now, FID is no longer supported in Chrome tools, though developers can still measure it using the PerformanceObserver API. Key tools like PageSpeed Insights and the Chrome UX Report will stop reporting FID in the coming days. Additionally, the documentation on

The post details personal strategies that have helped the author maintain good habits and enhance productivity in software development. Key points include: 1. **Small Commits**: Keep commits small to easily identify and revert changes if necessary, avoiding merge conflicts. 2. **Continuous Refactoring**: Follow the principle of making easy changes to improve the codebase regularly, aiming for half of all commits to be refactorings. This prepares the code for future requirements. 3. **Code as Liability**: Treat all

Cloudflare has announced a new open-source Rust crate aimed at reducing CPU utilization, thus enabling its CDN to better handle increasing web traffic. This initiative stems from the release of Pingora, a Rust-based proxy service, which processes over 60 million HTTP requests per second. A key component of this service, called "pingora-origin," is responsible for transmitting user requests to their final destinations while removing internal routing information. Currently, pingora-origin processes around 35 million requests per second. A specific function

The content discusses the challenges of testing system call (syscall) behavior in software, particularly how issues like disk space shortages or network timeouts can lead to syscall failures. It highlights the utility of the tool `strace` for tracing and modifying syscalls, allowing users to simulate errors, delays, and other behaviors to test code resilience. The author has added functionality in a project called Cirron that enables easy use of `strace` features from Python and Ruby. This includes simulating insufficient disk

The local-first revolution is transforming app development by allowing data to reside on users' devices for continuous access, even offline. This approach enhances performance and scalability, with local database solutions like RxDB leading the way. However, traditional databases struggle with semantic search and meaningful queries. Vector databases address this challenge by enabling data to be stored and queried based on meaning through machine learning. While many vector databases are designed for server-side use, the article proposes combining RxDB with transformers.js to create a local vector database

The blog post discusses the "Bugs in Hello World" phenomenon, where many programming languages' default print functions fail to handle errors properly. The author previously created a repository to track which languages exhibit this issue and how to fix it, using a modified version of a basic "Hello World" program in C as an example. While this version improves error handling, it does not address issues of internationalization or accessibility, nor does it include fsync functionality to prevent data loss during file output if a power

Ruby 3.0 introduced the GC.compact method to its garbage collector, enhancing memory management by mitigating fragmentation in long-running applications. Garbage collection is crucial as it frees memory by removing unused objects, but prolonged operation can lead to memory fragmentation, characterized by small unused gaps that hinder memory efficiency and degrade performance. GC.compact resolves fragmentation by rearranging objects in the memory heap, thus reducing gaps and optimizing memory usage. For instance, in a Ruby on Rails web application facing performance issues due to excessive

The content discusses the conflict between using Dotenv and Kamal in Rails for managing environment variables, particularly regarding their handling of `.env` files. Dotenv is commonly used in development, loading environment files based on priority, while Kamal uses the same `.env` file for deployment. This can lead to issues like accidentally using sensitive production values in development. To resolve this, the author suggests creating a separate `.env.development` file for development, while keeping a common `.env` file for shared
