Nate Bennett discusses the growing prominence of React in UI development, likening it to the foundational Linux kernel for front-end frameworks. He uses React for various projects, including video games and mobile apps, and believes that declarative, component-style frameworks represent the future of UI development. However, he notes that React has shortcomings, particularly in unit testing, which he finds challenging. Testing with React is complicated by its asynchronous UI updates and the nature of its rendering, making it hard to determine the state of

The release of Deepseek R1 has made a significant impact in the industry as it presents an open model capable of competing with OpenAI's offerings in complex reasoning tasks. Using Group Relative Policy Optimization (GRPO) and a reinforcement learning (RL)-focused multi-stage training method, Deepseek R1 was introduced alongside a research paper detailing its development. A key highlight from the paper is an "aha moment" where DeepSeek-R1-Zero, the model's initial version, autonomously learns to

The text discusses an experimental X11 window manager written in pure Ruby, emphasizing that it should be approached with caution due to its instability and potential to cause various issues, including data loss and crashes. Designed for tiling but allowing floating layouts, the window manager lacks window decorations and features like draggable or resizable windows. It requires external tools for keyboard handling and communication occurs via X11 ClientMessage events. Currently offering minimal multi-monitor support and relying on user input for development, this minimalist window manager is aimed

The content discusses Jane Street's experiences with building and releasing developer tools, particularly focusing on their build systems. It highlights their initial dissatisfaction with the OMake build system, which led them to create their own, called Jenga, around 2012. However, Jenga was not widely adopted due to compatibility issues and the requirement for users to embrace Jane Street’s specific development practices. Consequently, they decided to un-open source Jenga. In 2016, Jane Street developed Jbuilder, a simpler

Idempotency is an important yet often overlooked concept that enhances the resilience and performance of distributed systems, particularly for low-latency APIs facing stringent SLAs. It refers to the property of an action that yields the same outcome regardless of how many times it is performed. For APIs, this means that repeat requests result in the same effect as a single one. In contrast, non-idempotent actions, like incrementing a counter, produce different outcomes with each execution. Distributed systems are prone to various

The content emphasizes the importance of user feedback for the Stats application, which allows macOS users to monitor their system. Users can download the application from a provided link, with instructions for installation via both direct download and Homebrew. Stats supports macOS versions starting from 10.15 (Catalina) and requires certain configurations for optimal performance, particularly for M1 and Intel-based Macs. Data collection is energy-intensive; therefore, users are encouraged to disable some modules, like Sensors and Bluetooth, to reduce

Let’s Encrypt provides TLS certificates to over 550 million websites, having grown 42% in the past year. They issue approximately 340,000 certificates every hour and rely on a rate limiting system to manage high traffic. Initially using MariaDB, the old system faced challenges such as straining servers and long reset times. To address these issues, they implemented a new rate limiting system based on Redis and a virtual scheduling algorithm, capable of supporting over a billion active certificates. In 2015,

The blog post emphasizes the importance of "provenance" in pointer usage within programming languages like C, C++, and Rust. The author argues that even when two pointers refer to the same memory address, they are not necessarily interchangeable due to different contextual meanings. This post illustrates potential issues in optimizing compilers when provenance is overlooked, specifically using LLVM as an example, though the problems are not unique to it. The author presents a series of compiler transformations that seem intuitively correct but ultimately result in incorrect

The "Feisty Duck’s Cryptography & Security Newsletter," authored by Ivan Ristić, highlights the recent decision by Let’s Encrypt to discontinue support for online certificate status checking (OCSP) starting in May 2025. This change follows the realization that OCSP does not significantly enhance security, as many browsers either ignore it or implement it inadequately. Let’s Encrypt, which processes 12 billion OCSP requests daily, finds this service costly without security benefits. Consequently, once its current certificates

Many home and office printers embed invisible yellow dots, known as machine identification codes, into printed documents. These dots vary by brand and can contain information like the printer's serial number and print time, serving as a "signature" for forensic analysis by law enforcement. To see these dots, one needs a magnifying glass or a high-resolution image with adjusted color channels. Notably, not all printers leave these dots; industrial offset printers used for magazines and posters do not include them. Different brands have unique

The author reflects on the importance of taking time to think before making decisions, particularly in high-pressure situations. They share a personal experience during a client call where they hastily provided a deadline estimate, which led to regret. Since then, they have implemented a rule of not giving estimates on the spot and instead promise to follow up after taking time to consider. This approach helps them detach from emotions, identify blind spots, and gain perspective. The author cites Daniel Kahneman's similar practice of postponing

The author reflects on their experience landing a "full-stack" developer role, initially feeling excited about the multifaceted nature of the job. However, six months in, they found themselves overwhelmed and overburdened, highlighting that the term "full-stack" often means being expected to handle multiple positions for a single salary. They criticize job postings that demand extensive knowledge across numerous technologies, implying that this trend exploits developers rather than celebrates their skills. The piece emphasizes the challenging realities of the profession, contrasting initial

In the early 1980s, printed circuit boards (PCBs) in 8-bit home computers were designed differently compared to the early 2010s, where significant advancements in miniaturization and design occurred, notably the introduction of copper pours. Copper pours are computer-generated zones that fill the spaces between traces on a PCB, improving signal integrity and reducing RF emissions, which became increasingly important due to FCC regulations on unintentional radiators imposed in the 1980s. These changes were
