The blog discusses approaches to detect performance regressions in software, emphasizing that with the addition of new code, the app's memory usage and execution time can increase, potentially leading to performance issues. It highlights two methods for identifying regressions: proactively through PR reviews using the Macrobenchmark framework, which runs scenarios multiple times to produce comparative statistics, and reactively when users report performance issues, often lacking sophisticated tools. The focus of the blog is to identify which specific composable is causing regression, using tools like

In mid-2022, the author purchased the domain name musicbox.fun for an interactive online music project, unaware of its problematic history as a site that hosted pirated music. From June 2018 to February 2021, the domain received numerous copyright violation complaints and saw over 20,000 URLs delisted by search engines. After redirecting traffic from their previous domain to musicbox.fun, the author noticed a significant drop in organic search traffic, which they initially assumed was temporary. A

The content continues an overview of optimization algorithms, emphasizing the importance of prior sections and foundational concepts, particularly those from the book "Algorithms for Optimization." This part focuses on algorithms that use local models, such as derivatives, to improve designs incrementally. It introduces the line search method, an iterative approach for finding local minima, which involves: 1. Selecting a descent direction based on local information (e.g., gradient or derivative). 2. Choosing a step size for movement in that direction. 3. Re

Investigate Midwest provides insights into agricultural practices and policies impacting rural America. In a feature about farmer Josh Payne, the narrative highlights his transition from traditional farming to regenerative agriculture on his family farm near Kansas City, Missouri. After discovering he had an allergy to herbicides, Josh sought to implement a more sustainable farming approach, including the use of cover crops, sheep grazing, and orchards. However, he faced resistance from his grandfather, Charles Payne, who represented a generation of farmers entrenched in conventional practices

Elizabeth Chamberlain reports that nearly 15% of ice cream machines at McDonald's in the U.S. are currently out of order, with the rate rising to 32% in New York. A recent ruling from the U.S. Copyright Office marks a significant win for the Right to Repair movement, allowing legal repairs of commercial food equipment like McDonald's ice cream machines without violating copyright law. This change challenges the digital locks imposed by manufacturers such as Taylor, which have historically limited access to repair information,

CSS has seen significant advancements, particularly with the introduction of the CSS @property rule as part of the CSS Houdini specification. This feature allows developers to create custom properties (CSS variables) with enhanced control, including type validation and default values. The @property rule enables the definition of property types (like number, color, or length) and controls their behavior, which enhances dynamic styling capabilities. A basic syntax for the @property rule is provided, illustrating how to define a custom property for element rotation.

The recent advancements in large vision-language models, particularly GPT-4V, demonstrate significant potential for operating within user interfaces. However, the effectiveness of these multimodal models as general agents is limited by shortcomings in screen parsing capabilities. Specifically, there is a need for a robust technique that can reliably identify interactable icons and understand the semantics of UI elements within screenshots. To address these challenges, the authors introduce OMNIPARSER, a method designed to convert user interface screenshots into structured elements. This approach enhances

The post provides an overview of SELinux (Security-Enhanced Linux), its implementation, and methods for bypassing it, particularly in the context of Android kernel exploitation. The tests were conducted on three devices: Samsung Galaxy A34, Huawei Mate 20 Pro, and Xiaomi Redmi Note 12, with a focus on the first two due to their hypervisors which complicate privilege escalation and SELinux bypassing. SELinux is a Linux kernel security module that enforces Mandatory Access Control (MAC)

The concept of "deep functions," as introduced by Dr. Ousterhout, emphasizes the importance of designing functions that simplify complex tasks with a clean and minimal interface. The aim is to hide underlying complexity while providing users with an easy-to-understand way to interact with the function. A notable example is JSON.parse(), which simplifies JSON string parsing into a single, straightforward call despite doing complex work behind the scenes. When writing functions for others, the focus should be on ease of use and understanding rather

Web and software developers today enjoy greater empowerment, yet there is a concerning trend: an increasing dependence on frameworks, libraries, and pre-packaged solutions like Laravel, React, Angular, and Django. While these tools enhance development efficiency and scalability, they also risk stifling creativity and promoting uniform solutions. Many developers prioritize mastering these frameworks over understanding the underlying technologies, such as PHP, Python, or JavaScript. For instance, with Laravel, the abstraction of database management via Eloquent ORM helps expedite development
