The author discusses their experience using Binaryen's Asyncify to implement the setjmp function in WebAssembly, allowing ExifTool to run in the browser despite limitations with larger files due to WASI libc's reliance on an unsupported exception handling feature. Files over 2GB can't be processed due to browser memory restrictions, leading the author to propose a memory file system that uses pointers to files instead of loading entire files into memory. The File API and Blob type enable slicing files to access specific data ranges without

When eBPF pt_regs reads return garbage on the latest Linux kernels, blame Fred

Published: 2025-03-01 | Origin: Hacker News

In Linux kernel version 6.9 for x86_64, a new configuration option called CONFIG_X86_FRED has been introduced, which adds 16 bytes of padding to the start of a task's kernel stack area. This change requires updates to any code handling raw kernel stack and pt_regs lookups. The author has been using Ubuntu 24.04 with the original kernel version 6.8.0 for eBPF development without issues. However, after upgrading to the optional kernel

Self-Hosting a Firefox Sync Server

Published: 2025-03-01 | Origin: Hacker News

The author switched from Firefox to LibreWolf and became interested in setting up a self-hosted Firefox Sync server. Although they had previously heard of this possibility, they only decided to explore it now. They found Mozilla’s syncserver repository, which combines both the authentication and storage components needed for a sync server but encountered some challenges. Instead, they opted for syncstorage-rs, a modern Rust-based version, yet struggled with the lack of a ready-to-use Docker image and complicated Docker documentation. Eventually,

Why it's so hard to build a jet engine

Published: 2025-02-28 | Origin: Hacker News

Civilization faces significant technical challenges that demand high performance at low costs. Achieving extraordinary performance often involves complex technologies that operate near their limits. For example, constructing a 500-story building requires advanced building technologies, unlike a simpler five-story structure. Balancing cost with performance complexity poses additional challenges, necessitating strategies to reduce maintenance costs, avoid expensive materials, and ensure designs can be produced cheaply with minimal expert labor. Examples of such challenges include building advanced semiconductor fabrication plants, developing new commercial aircraft, and

How to gain code execution on hundreds of millions of people and popular apps

Published: 2025-02-28 | Origin: Hacker News

The author explored the installation process of the AI text editor cursor and discovered that the installer was managed by an Electron app bundler called todesktop. After creating an account on todesktop, they noticed the application used Firebase, specifically Firestore as its database, and conducted reconnaissance using developer tools. They found an insecure Firestore collection named "temporaryApplications," which was later clarified by todesktop to contain no sensitive data. The author also looked into the npm package @todesktop/cli, which manages

Order Stamps – A String-Based Trick for Effortless List Ordering

Published: 2025-02-28 | Origin: /r/programming

Orderstamp is a lightweight TypeScript utility designed for efficient management of ordered lists in databases, providing O(1) insertions and reordering. Initially developed for GoatDB, this standalone package addresses common challenges in maintaining list order, allowing only minimal write operations. Key features include: - String-based ordering based on the principle of continuity, enabling easy insertion, deletion, or reordering by assigning new order stamps with just one write operation. - Functions to generate order stamps at the beginning and end of

The author encountered a severe issue with their machine, experiencing 3,200% CPU utilization across all 32 cores, compared to a prior case of 100% usage on a single core. Using Java 17, they analyzed thread dumps to identify a problematic section in the code located at BusinessLogic:29, where a loop incorrectly iterated over an unrelated object instead of the relevant one. They suspected that refactoring had made the unrelated object redundant. To test their hypothesis, they ran unit

In her article, Miriam Suzanne emphasizes the importance of using relative units like em and rem for text sizing in web design, highlighting their role in ensuring compatibility with user preferences and maintaining consistent typography. She discusses how the default text size set by browsers can be leveraged by establishing a root font-size with em values, which allows for a scalable relationship across various font sizes. Suzanne also introduces the concept of fluid typography, which incorporates viewport or container-relative units and the clamp() function to create responsive text sizing within defined
