The article discusses recent updates to React ProseMirror, specifically its new support for server-side rendering (SSR). It notes that the library relies on React's `useLayoutEffect` hook, which is used for managing side effects that involve reading from the DOM. This hook allows for precise layout adjustments before the browser renders changes. However, when components that utilize `useLayoutEffect` are rendered on the server, issues arise because there is no DOM on the server. Consequently, React cannot execute layout effects

The content discusses how to create self-referential lists and dictionaries in Python through simple examples. It explains that when assigning a list or dictionary to a name and its own element at the same time, Python handles the assignment in a way that allows the element to reference the list or dictionary itself. This behavior can seem confusing since it may appear that the variable is not yet defined when it's being used in its own assignment. However, as outlined in the Python Language Reference, the assignment process evaluates the expression

A robotic lunar lander named Blue Ghost, developed by Texas-based Firefly Aerospace, successfully landed on the moon early in the morning at 2:34 a.m. CT. Launched in January aboard a SpaceX rocket, Blue Ghost has become the second private company to achieve a soft lunar landing, following Intuitive Machines' IM-1 mission last year, which faced challenges upon landing. Firefly’s mission is a part of NASA's Commercial Lunar Payload Services (CLPS) and Artemis programs

Nebu is a graphical spreadsheet editor for the Varvara system, designed for working with CSV/TSV files. Users can perform mathematical operations by specifying a rectangular range of cells followed by an operator. A range is defined using a colon between two cell identifiers, and each cell can only perform one operation without including itself recursively in the range. The supported operations include the basic arithmetic operators (+, -, *, /), counting non-empty cells (#), and string concatenation ("). If no operator is specified,

Lars Wirzenius reflects on the early days of Linux, detailing his experiences from the inception of the operating system. He recalls starting his computer science studies at the University of Helsinki in 1988, where he met Linus Torvalds. They both became interested in Unix and exploration of Usenet, leading to discussions about operating system design. After completing military service, they returned to their studies and took a course focused on C and Unix programming. In 1991, Linus acquired a

On November 12, 2022, during the Wings Over Dallas air show in Texas, two WWII-era warplanes collided in midair, resulting in the deaths of six crew members. A Bell P-63 fighter struck the Boeing B-17 “Texas Raiders” in a catastrophic incident, raising concerns within the Commemorative Air Force, which organized the event, about potential flaws in collision prevention procedures. However, the National Transportation Safety Board's report highlighted that the real issue was the absence of

Rungestraße 20 is hosting the first quarterly Swapfest in collaboration with the hacker space c-base in Kreuzberg, Berlin. This event is designed for attendees to buy, sell, and swap electronics, computer equipment, and tools, promoting the right-to-repair and reuse principle. Participants are encouraged to bring unused items to find them a new home. Selling at the event is free, but a deposit may be required for larger items to cover disposal costs if they are not taken back. Sellers

A space mission focused on mapping the Dark Universe has successfully observed a rare phenomenon known as gravitational lensing. This occurs when galaxies bend light from other galaxies, creating distorted or multiple images. The most striking case observed by the Euclid mission was a perfect Einstein Ring, formed by light being bent due to a rare alignment of galaxies. Gravitational lensing has historical roots dating back to the 1700s, but it was not until Einstein's General Theory of Relativity in 1915 that

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
