Ladybird is a new browser engine that is part of the SerenityOS project and is currently in pre-alpha development. The author is focusing on the JavaScript engine, LibJS, which has an interpreter tier but no compilation tiers yet. LibJS incorporates modern optimizations and includes extensive verification checks to mitigate security vulnerabilities such as integer overflows. To test LibJS, the author is using Fuzzilli, a JavaScript fuzzer that can trigger specific bugs. The fuzzer was set up after addressing

A recent study from Cornell University reveals that AI writing assistants, widely used in various applications, may negatively impact users from the Global South, particularly India. The study found that these tools tend to produce generic language that aligns more with American writing styles, resulting in a loss of cultural nuances in Indian writing. Although the AI improved writing speed for both Indian and American users, Indians experienced less productivity due to the need to correct the AI’s suggestions. Senior author Aditya Vashistha highlighted concerns about cultural

Liverpool FC recently secured their second Premier League title, bringing their total championship wins to 20, which ties them with Manchester United for the most English titles. This achievement has unveiled a fascinating numerical coincidence for mathematicians: when ranking Premier League winners by title counts, the numbers form a sequence that resembles the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13). This sequence, known for its appearance in various natural phenomena, is notable because each number

The post discusses the complexities involved in getting and limiting the length of strings in programming, which are common tasks but can lead to bugs and vulnerabilities. It emphasizes that while string length functions may appear straightforward, they can be misleading due to technical nuances. The author highlights four common measures of string length used in programming languages: UTF-8 bytes, UTF-16 code units, Unicode code points, and grapheme clusters. A "character" is defined as the smallest unit of written language, encompassing letters

Zhaoxin, a Chinese x86 CPU designer and joint venture between VIA Technologies and the Shanghai municipal government, has released its latest CPU, the KaiXian KX-7000, featuring a new architecture called "世纪大道" (Century Avenue). This architecture, named after a Shanghai landmark, aims to enhance performance, building on Zhaoxin's previous CPU, the KX-6640MA, which struggled with modern applications due to its older 2-wide core design. The KX

In April, significant advancements were made in running x86-64 programs on RISC-V Linux, particularly thanks to donor support, including a notable $1000 contribution from Sonicadvance1 of FEX-Emu for hardware and games. The process of using a GPU with a RISC-V board proved to be challenging. After initial attempts with an NVIDIA GTX 1050 Ti and an AMD Radeon HD 7790, success was achieved with an AMD HD 7350 due to better compatibility.

Developing applications that require secure storage of sensitive data can be challenging, particularly with Azure Key Vault, which is a reliable security product for protecting items like API keys and certificates. In a development environment, deploying an actual Azure Key Vault is often necessary, leading to complications such as navigating security policies and potential delays due to access issues. To address these hurdles, Microsoft has released a stable version of the Azure Key Vault Emulator, which allows developers to simulate the Key Vault functionality locally. This emulator can be run

The author recounts their journey into Linux kernel exploit development, sparked by a seemingly simple bug patch labeled exp237 from the KernelCTF submissions. Intrigued by the ease with which a researcher escalated privileges using this bug, they decided to explore it further, even at the cost of their GPA. The process involved setting up a debugging environment with QEMU and using the gef-kernel GDB extensions while working within WSL on a Windows computer. The patch in question addressed a transport reassignment

The content discusses a method to combine data from two separate computers—one that stores a user's name and another that stores a favorite color—into a single interactive component within React. It introduces the concept of splitting the component into two parts: **GreetingBackend**, which reads the color data from one computer, and **GreetingFrontend**, which interacts with the user and displays the greeting. The backend component serves as the source of truth, supplying the data to the frontend, and maintaining React's top-down data

The post discusses the challenges that arise in a Rails app as it gains consistent traffic, particularly regarding slow SQL queries. While ActiveRecord has improved in performance and user experience, it can still generate inefficient SQL due to common pitfalls like N+1 queries and unnecessary data loading. Although databases, such as MySQL and PostgreSQL, can provide information on slow queries, they often don't offer actionable insights, making it difficult to correlate performance issues with specific code in ActiveRecord. The process of analyzing slow query logs

The article discusses optimizing JavaScript performance for responsive web applications by focusing on how the V8 engine compiles JavaScript functions. It highlights that during script processing, V8 can either compile functions eagerly or defer their compilation, impacting webpage loading speed. Eager compilation of functions called during page load improves performance, with a study showing significant reductions in parse and compile times for various popular web pages. A new feature called Explicit Compile Hints allows developers to control which JavaScript files and functions are compiled eagerly,
