The article discusses the initial technical challenge of building a cross-platform search engine with encryption capabilities, specifically focusing on data storage across different platforms. While writing to the filesystem is manageable on desktop and mobile, doing so in a browser introduces unique constraints that complicate the process. The author explores various storage solutions within the browser ecosystem, starting with LocalStorage, which, despite its simplicity, has size and type limitations. IndexedDB offers a more robust alternative but presents complexities and requires handling numerous edge cases. Ultimately,

In March 2025, a reflection on Brian Eno's influential ambient album "Music for Airports" reveals his original intention for the piece: to create music that addresses the acceptance of mortality rather than evading it with cheerfulness. Released in 1978, the album was developed from tape loops created during a lengthy improvisation session, emphasizing slow, meditative sounds that veer away from traditional major and minor scales. For those seeking an extended experience, a six-hour time-stretched version exists

Seven years ago, the author envisioned Rust as a strong language for fast SIMD (Single Instruction, Multiple Data) programming in a blog post titled "Towards fearless SIMD." Currently, while there has been progress, the experience of writing SIMD in Rust is still challenging. The Linebender projects, which previously did not utilize SIMD, are now beginning to integrate it, especially in CPU/GPU hybrid rendering and areas like color conversion and 2D geometry acceleration. The blog serves as a companion to a podcast

The text emphasizes the importance of user feedback and describes the functionality of dotbins, a tool that helps manage CLI binaries within a user's dotfiles repository. Unlike other tools, dotbins integrates tool-specific shell configurations (such as aliases and completions) directly into the dotfiles workflow, allowing users to easily manage tool installations without needing a package manager or sudo permissions. Dotbins was created to address frustrations experienced when setting up new environments, as it allows users to clone their dotfiles repository and have not

The author discusses their experience working on a Go project and testing endpoints using the `httpx` Python package in an IPython REPL, favoring it over `curl` for its flexibility in handling responses and payloads. They created a script, `jam_users.py`, to upsert user data for testing the `/users` endpoint. However, they found it inconvenient to run the script without relying on a compatible system Python installation. The author has been using `uv` as a package manager

The thesis advocates for creating a Linux distribution that runs Windows binaries by default using Wine due to a significant compatibility issue with Linux binaries. The author notes that while Windows executables from decades ago can still run today, Linux binaries often struggle with compatibility due to frequent updates and variations in library versions across different distributions. The author explains that, although Linux system calls are stable, the standard C library (libc) is not, leading to a broader binary compatibility problem. There are multiple (four major)

Until recently, Android apps could access all other apps on a device without user permission. Since Android 11 (2022), Google has implemented a package visibility policy that restricts this access. Apps can only see other installed apps if it is essential for their functionality, which must be declared in the AndroidManifest.xml file. Certain apps, like file managers and antivirus tools, can request QUERY_ALL_PACKAGES permission for full visibility. An individual curious about Indian apps checked the manifest files of several applications to see

Namanyay Goel reflects on his experience debugging an AI development tool, contrasting his code comprehension with the emerging trend of "vibe coding" discussed by Andrej Karpathy. Vibe coding refers to the practice of relying on AI tools for coding without fully understanding the code being generated, as exemplified by Karpathy's admission to frequently accepting code without reviewing errors. While Goel utilizes AI tools, he emphasizes the importance of maintaining an understanding of his codebase to effectively troubleshoot issues. He cites

LaTeX is the preferred authoring platform in mathematics, physics, and computer science due to its high-quality typesetting capabilities, especially for formulas and diagrams. However, it primarily produces PDF output, which is not accessible, lacks scalability for devices like tablets and smartphones, and does not provide semantic information, making it challenging for users who need alternative formats (e.g., audio, Braille) or different display options. A better solution is to provide content in HTML, which is more accessible and compatible

The article discusses the author's journey with using an immutable Linux distribution, initially planned as a critique but evolving into a more extensive exploration. After purchasing a new laptop that required a stable operating system for college, the author chose Fedora Silverblue, known for its unbreakable nature. This distribution is part of a category of "Atomic" Linux systems, which are designed to be immutable and manage updates through a version control-like mechanism called rpm-ostree. Applications are typically run as Flatpaks, ensuring
