The content is a catalog highlighting the atomic operations provided by UNIX-like/POSIX-compliant operating systems, useful for developing thread-safe and multi-process-safe programs without the need for mutexes or read/write locks. It emphasizes the importance of allowing the kernel to handle operations efficiently, rather than using CPU time on unnecessary locking when an operation is already atomic. The author notes that these operations are best applied to local filesystems, as they may not work correctly with NFS mounts due to multiple kernels. The

The author attempted to delete their Tower of Fantasy account from over four years ago but struggled to find a way to do so without reinstalling the game, which is over 100 GB in size. While waiting for the lengthy download, they explored the launcher directory and discovered a kernel driver, GameDriverX64.sys. They noted that while anti-cheat drivers are meant to protect games by operating with high privileges, poorly written drivers can pose security risks, as they can become attack surfaces that could compromise the

Sergey Tselovalnikov highlights the evolving role of Quality Assurance (QA) in software development, emphasizing its increasing centrality compared to merely building software. Over the past year, he has noticed a shift in his approach to code changes, where he now prioritizes how to test functionality rather than focusing solely on creating a working prototype. He notes that the effectiveness of coding agents relies significantly on their ability to verify their outputs, a process that can often lead to presenting incorrect or incomplete code. While coding

Nicholas Carlini, a researcher on the Safeguards team, shares insights from an experiment with "agent teams," which consist of multiple Claude instances working on a shared coding project without human intervention. He tasked 16 agents with creating a Rust-based C compiler capable of compiling the Linux kernel, resulting in a 100,000-line compiler after extensive sessions and significant costs. Carlini highlights the challenges of programming autonomous agents, emphasizing the need for effective testing and work structuring to maintain continuous progress without

Postman recently announced significant updates in March 2026, marking a dramatic evolution from its original role as a simple API testing and documentation tool to a complex cloud-based platform. The changes reflect a trend towards feature bloat, resulting in a product that increasingly integrates numerous capabilities, potentially leading to vendor lock-in for users. Notably, Postman aims to transform into an all-in-one platform for building and deploying AI-powered APIs. Key new features include: 1. A visual “Agent” block system

The blog post discusses the benefits of running your own data center rather than relying on cloud providers for compute needs. The author highlights that managing a personal data center fosters self-reliance and better engineering practices by focusing on real-world challenges instead of complex cloud billing and APIs. It also provides incentives for engineers to improve efficiency since additional compute power isn't just a budget increase away. Furthermore, operating your own data center can be more cost-effective, especially for consistent compute or storage requirements common in machine learning. The

In 2025, Flutter experienced significant maturation and disruption. The transition to the Impeller rendering engine was finalized, enhancing performance on iOS and Android by addressing shader compilation issues. While Skia remained available on the web and for devices below Android API 29, API 29 and above defaulted to Impeller. The introduction of stateful hot reload for web development aligned it with mobile, contributing to a rise in Flutter's usage among new free iOS apps, from about 10% in

The content discusses the Concurrency Control problem, highlighting the challenges of handling concurrent updates in systems, particularly in user-facing applications or services. An example illustrates a situation where two users attempt to update a budget simultaneously, leading to one update being overlooked, resulting in inaccurate final data. This issue also occurs in asynchronous service communications, where two actions can conflict and cause unintended outcomes. The content emphasizes the need to prevent situations where one update overrides another, either from individual users or from automated services. One proposed

The author reflects on the evolution of Responsive Web Design, recalling its prominence over a decade ago, particularly highlighted by Nicolas Barrera's talk. While mobile-first design has become a norm given the prevalence of mobile screens, many code samples still lead to issues like horizontal scrolling or hidden overflows. Programmers, including the author, often prefer larger screens for consuming programming content, which requires extra effort when preparing code snippets for publication, whether through manual formatting or using code formatters. These formatters typically adhere

Catherine (Whitequark) recently highlighted issues found in poorly-engineered firmware, particularly in certain CPUs. She points out two notable examples of errors from Intel that, while not critically damaging, are noteworthy. One example is the misspelling "GenuineIotel" (instead of "GenuineIntel") reported by some Intel processors like the Xeon E3-1231 v3. This could potentially stem from a random bit error in the encoding. The second example is the Core i
