Recently, an update to the version manager asdf, which was rewritten in GoLang, caused issues with installations on macOS, Linux, and WSL. Asdf allows users to manage multiple programming language versions, such as Python and Ruby, and serves as an alternative to tools like rvm. After the update, the author encountered problems with their Ruby interpreter, which defaulted to the macOS version instead of the asdf-managed version. They typically perform updates cautiously, specifically during routine maintenance.

After seven years of building mobile apps, the authors recognized the challenges of app development compared to websites, particularly when using React Native. To address these issues, they created a platform featuring an AI app generator that quickly creates custom React Native apps based on user prompts, complete with an instant live preview. They showcased this capability with a demo that reconstructed the Hacker News UI. Their platform, a0.dev, is designed for rapid prototyping, allowing users to generate both functional screens and games. It includes models

In the previous post, the author expressed frustration with the lack of exnref support in WebAssembly runtimes, which hindered the usability of zeroperl. Instead of merely complaining, the author took the initiative to implement a solution. To maintain compatibility across different WebAssembly runtimes, the author chose to create a custom implementation of setjmp/longjmp, rather than using the libsetjmp from the WASI SDK. They utilized Binaryen's Asyncify feature to build this implementation. The

The author discusses the discovery of "mouse tape," a product designed to protect car wires from rodent damage by making them unappealing to gnaw on. Developed by Honda, the tape is coated in capsaicin, making it spicy. Intrigued, the author orders the tape, feeling compelled to use a recent $50 Venmo donation for the purchase. Upon receiving it, the author has second thoughts about the implications of the tape's design, which features mice with an "X"

Microsoft has released an update for Visual Studio Code (VS Code) to version 1.97, introducing GitHub Copilot as an "out-of-the-box experience" and previewing a new WebGPU rendering feature. This substantial release is notable as it breaks the typical monthly cycle due to the holiday season. The inclusion of a free Copilot plan means updates will now be tracked as part of the main product, though the free plan has limitations of 2,000 code completions and 50

The author reflects on their experiences with MUDs (Multi-User Dungeons), text-based multiplayer games popular in high school. They enjoyed the accessibility of these games, which could be played on various machines via Telnet without graphics, allowing easy concealment from teachers. As their interest shifted from playing to building MUDs, they found excitement in creating game environments and characters through in-game commands, despite the challenges posed by limited tools and a clumsy interface. Many of their projects were ultimately abandoned

The blog post discusses implementing order-independent keyword arguments in C++ using the proposed reflection features of C++26. The author discovered a technique while experimenting with reflection and shares it as a showcase of the potential of these new features. Despite numerous attempts over the years to introduce keyword arguments in C++ (notably addressed in EWG issue 150), none have been successful, leading to creative workarounds. One approach mentioned is the use of designated initializers introduced in C++20, which allows for

A supply chain attack targeting Go developers was discovered involving the Go Module Mirror, a service run by Google to cache open source packages. The mirror hosted a backdoored version of a popular module, boltdb-go/bolt, for over three years due to a technique called "typosquatting." This technique allows malicious files to be named similarly to legitimate ones, leading developers to accidentally download compromised versions when they mistyped package names. Although the original malicious module on GitHub was reverted to its

The discussion centers on the challenges of validation in the context of commands, particularly highlighting the tendency of some to attempt validating all aspects at once, even when they are unrelated. The article uses the analogy of a command issued by Alice to Bob, illustrating how commands can vary in clarity and execution. For example, while Bob can straightforwardly fulfill Alice's command to fetch a broom and sweep the kitchen, various obstacles like missing items or unforeseen circumstances (e.g., an already occupied floor) can impede execution.
