The content discusses enhancing the user experience (UX) when submitting Turbo forms by adding a loading spinner to the submit buttons. During the wait for a server response, there is often little visual feedback, especially in modals or on slow connections. To address this, a small Stimulus controller can be implemented to update the button without disrupting the submission process. It is suggested to maintain the button's width and style the disabled state. Additionally, there is a method using `data-turbo-submits-with`

The author previously outlined the requirements for an app to be considered a competitor to Signal and advised against using the Session app, a fork of Signal. The main reason for this recommendation is Session's removal of forward secrecy, a critical security feature that protects against Key Compromise Impersonation (KCI) attacks. This undermines the app's security and raises concerns about potential malicious intent behind the change. The author emphasizes the importance of maintaining robust cryptographic protocols and suggests that some users are overly attached to

The author argues that the main benefit of using async/await in Rust is not primarily performance, but rather its ability to simplify the expression and composition of complex concurrent processes. During a Rust course, the author noted that discussions about async often focus on performance, leading to criticism that the performance gains may not justify the complexities introduced by async programming. In contrast, the author believes that the true value lies in how async/await makes code more elegant and manageable. The post will explore various motivations for adopting async

Designer and educator Angie Wang has explored a newly donated collection of over 500 chopstick sleeves, or hashibukuro, at the Archive. These sleeves trace back to the Heian period (8th–12th century) in Japan, where ladies-in-waiting wrapped chopsticks in silk to maintain decorum. By the Edo period (17th–19th century), these sleeves were commonplace at shogun banquets and in the Yoshiwara district. The advent of disposable chop

The Australian Open has introduced a unique broadcast option for international viewers by offering matches on its YouTube channel with animated caricatures of players instead of the actual footage. This approach allows the tournament to bypass certain broadcasting obligations and rights issues by postponing the live stream and using cartoon representations. In Australia, the event is accessible on free-to-air television via Channel 9 and its streaming services, while viewers in Europe and North America require pay-TV access through Eurosport and ESPN, respectively. Despite the innovative approach

The guide explains the importance of understanding time and space complexity when writing efficient and scalable code. It introduces Big-O notation, which serves as a framework for analyzing how an algorithm's performance and memory requirements scale with input size, particularly in worst-case scenarios. Key principles include ignoring constants and lower-order terms to simplify complexity analysis. The guide categorizes time complexities from fastest to slowest growth rates, including constant time (O(1)), linear time (O(n)), and quadratic time (O(n²)).

The text discusses the differences between genre fiction and literary fiction. Genre fiction, such as slasher films or murder mysteries, is characterized by familiar themes and structures that shape audience expectations, making it easy to read and understand. In contrast, literary fiction aims to challenge readers by making the familiar seem strange, encouraging a deeper perception of the world. When creating software, the focus should be on the simplicity and predictability typical of genre fiction, fostering a sense of familiarity for the user. Understanding how genres

Cerebras has successfully challenged the conventional wisdom in semiconductor manufacturing, which states that larger chips result in poorer yields. They have developed a chip that is 50 times larger than traditional computer chips, achieving comparable manufacturing yields. The key to this success lies in their innovative approach to fault tolerance in relation to chip size. This article compares the manufacturing yields of Cerebras's Wafer Scale Engine to an H100-sized chip, both produced at 5nm, exploring how defect rates, core size, and
