The narrative chronicles a three-year endeavor to transform a fleet of discarded laptops into an extraordinary video wall, crafted in collaboration with Aksel Salmi, who designed the hardware, while the author focused on the software development. The project began when their Design teacher, Mr. Bush, proposed utilizing the school's old Chromebooks, specifically the Lenovo ThinkPad 11e, which the author fondly remembers using in childhood. Despite their sentimental value, these laptops have become obsolete, lacking updates and functionality, which

The article discusses the Git tool `range-diff`, which is used to compare two versions of a series of patches. The author notes that many people may not be aware of this command's existence. `Range-diff` summarizes the differences between two similar versions of a branch, which can be particularly useful for reviewing code changes. The example provided illustrates how to handle feedback on a pull request when a developer accidentally leaves in debugging lines alongside their feature addition and documentation. The typical approach involves adding a new

A data model outlines how data is structured in a database, and traditional CRUD applications use a single model for both reading and writing data. This can lead to performance issues and complexities as applications grow, as read operations optimized for speed may conflict with write operations focused on data integrity. The Command Query Responsibility Segregation (CQRS) pattern mitigates these issues by separating read (query) and write (command) operations into distinct models. The command model focuses on data integrity and business logic during create,

Amit Assaraf recently published an article claiming that the "Material Theme" extension for VS Code is malicious, citing a deep analysis that supposedly reveals multiple red flags. However, the analysis is criticized as insufficient and primarily serves as marketing for a startup's threat analysis tool, which provides vague and paywalled information. The article's claims are called into question, especially since an independent run of another extension through the same tool resulted in a lower risk score despite its complex features. The VSCode team

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

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

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,

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

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

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
