The article discusses "Copy-and-patch Compilation," a method for creating a baseline Just-In-Time (JIT) compiler that allows for rapid runtime code compilation while being easy to maintain. This approach requires minimal knowledge of assembly language and generates native code comparable in quality to traditional baseline JITs, which focus on quick code generation rather than deep optimization. The process involves defining "stencils," which are small C functions that perform specific operations, compiling them into native code, and then patching them

The provided content appears to be a portion of a PDF file encoded in binary format. As such, it contains metadata structures, compressed data, and is not meant to be directly interpreted as human-readable text. The PDF format includes objects like streams and compressed content, which often represent images or binary data following encoding standards. Without specific readable text or context, it's impossible to summarize its content meaningfully beyond noting its technical structure as part of a PDF document.

The Aisuru botnet, now primarily fueled by compromised Internet-of-Things (IoT) devices from major U.S. Internet providers like AT&T, Comcast, and Verizon, is causing significant concern due to its record-breaking attack capacities. Since emerging over a year ago, Aisuru has eclipsed other IoT-based botnets, drawing from around 300,000 infected devices globally, including consumer-grade routers, cameras, and digital recorders that often use outdated or insecure software. The

On October 7, 2025, the React team announced the first stable release of the React Compiler, a tool designed to optimize React and React Native applications automatically without requiring code rewrites. This compiler has been thoroughly tested on major Meta applications and is now production-ready, incorporating automatic memoization to enhance performance. The development of the React Compiler represents nearly a decade of engineering effort, beginning with the Prepack project in 2017, which ultimately influenced the design of Hooks. Since its initial

Turbo Stream elements are custom HTML components that modify the DOM when included on a page. The <turbo-stream> tag allows for seven different actions that can manipulate the DOM: append, prepend, replace, update, remove, before, and after. For instance, after a user submits a form to create a new book, the server can respond with a <turbo-stream action="append"> element containing the new book entry, which Turbo then adds to the DOM. Two main questions arise: how

The 2025 DORA Report highlights that while AI adoption in software engineering is nearly universal, with 90% of respondents using AI tools and over 80% believing it enhances productivity, these beliefs can be misleading. Studies indicate that while developers feel AI tools improve their efficiency by 20%, they might actually slow them down by 19%. Additionally, gains in individual coding speed do not always translate to improved productivity throughout the software delivery lifecycle, which remains hampered by systemic obstacles such as unreliable pipelines

The author reflects on the difference between proving algorithm correctness in academia and the reliance on testing in the software industry. While testing can ensure that an application works with specific examples, it cannot guarantee that it functions correctly in all scenarios. The complexity of real-world software is often cited as a reason for this disparity, leading some to liken software behavior to biological processes, which lack predictability. However, the author emphasizes that software is ultimately deterministic, meaning consistent inputs will yield the same outputs. They argue that

The text discusses the challenges of integrating Lisp, a tree-based programming language, with ed(1), a line-oriented text editor. The author expresses a desire to combine these two "wolves" in their programming identity but acknowledges the difficulties due to their differing structures. Lisp typically requires a more complex syntax with nested parentheses, making it unsuitable for line editing in ed. The author suggests a potential solution: transforming Lisp code into a more line-oriented format by isolating self-contained forms on their own lines, inspired

The author discusses the evolving landscape of programming, suggesting that it is a temporary phase as artificial intelligence (AI) increasingly assumes programming roles. Drawing from science fiction, particularly "Star Trek," the author notes that characters interact with advanced computers without engaging in programming activities. Instead, users communicate their needs directly to AI, which intuitively understands and executes tasks without requiring coding. The piece highlights that, in many futuristic narratives, technology is depicted as self-sufficient, with programmers becoming obsolete and replaced by roles focused

Swift is a general-purpose programming language known for its safety, performance, and ease of use, but it has struggled to extend beyond mobile development into broader workflows, particularly in scripting. Historically, scripting in Swift has been challenging and not user-friendly, diminishing its practicality even for simple tasks. However, a new package called swift-subprocess, released recently, aims to address these issues and improve the scripting experience. The article plans to explore what scripting entails, why it's been difficult in Swift, and how

The content emphasizes the importance of user feedback and introduces "nanochat," a full-stack implementation of an LLM similar to ChatGPT. It is designed to run efficiently on an 8XH100 node using a script called `speedrun.sh`, which handles the entire process from tokenization to web serving with a user-friendly interface. The script training and inference process takes about 4 hours, costing approximately $100. Users are guided on how to set up a new 8XH100 GPU

Programming languages have rapidly evolved, but software development often still relies on outdated interfaces for runtime parametrization using environment variables (envvars). These envvars lack organization and types, existing as a flat global dictionary of strings. They are passed from parent processes to child processes during execution via the execve system call on Linux. While most tools (like Bash and Python) naturally pass the parent environment to children, some, such as the login executable, create a fresh environment. The environment is managed in a static

The author invites readers to subscribe to a blog for updates on new posts and emphasizes the importance of understanding science, particularly in the context of the Trump Administration's perceived war on it. The piece highlights that the general media, scientific journals, and universities often fail to effectively communicate what science is, how it operates, and its relevance to everyday life. In the post, the author aims to demystify science by explaining the roles of scientists, engineers, entrepreneurs, and venture capitalists in fostering innovation and
