The author shares their experience of participating in an experimental shuttle to design a JTAG interface using Global Foundries' 180nm technology, motivated by the current trend of AI accelerators. Initially, the project began with a focus on in-silicon debug infrastructure, later evolving to include a systolic matrix multiplication accelerator as the design under test. The tapeout was conducted as part of a Tiny Tapeout initiative but within an experimental framework aimed at testing new nodes and flows. Participation in these shutt

The content discusses a common issue in server management where an application experiences connection problems despite low CPU usage, ample RAM, and idle disk I/O. The root cause is often socket saturation rather than computational limits, particularly in Linux where each TCP connection uses a file descriptor (FD). Although the maximum FD limit may seem high (e.g., 65,535), a bottleneck can occur if the application employs a thread-per-connection model that ties up resources with slow clients. A scenario exemplifying this

Researchers from the Keck School of Medicine at USC have reported a significant reduction in nitrogen dioxide (NO₂) levels linked to the increase of zero-emissions vehicles (ZEVs) in California between 2019 and 2023. The study revealed that for every additional 200 ZEVs introduced, NO₂ levels decreased by 1.1%. This analysis, using satellite data, is one of the first to provide concrete evidence of the health benefits associated with ZEVs, which include

Eclypsium has acquired an industrial X-ray machine to conduct cybersecurity research, including analyzing components for major companies. A recent experiment involved X-raying both an old, dysfunctional USB to UART cable and a new, verified one purchased from DigiKey. The older cable, which had performance issues when transferring firmware, raised suspicions of being counterfeit, possibly stemming from a flawed production run or unauthorized replication of FTDI technology. FTDI has acknowledged challenges with counterfeit devices, even implementing drivers that disable counterfeit chips

The content discusses the limitations of AI-generated content and the misapplication of AI agents in productivity. The author notes that despite rapid development with agents, much of it goes unused due to a lack of practical application. The main issue is treating AI agents as strategic tools rather than execution tools. When tasked with vague goals, agents produce impressive but ultimately unusable results, whereas specific tasks yield significant benefits. The author distinguishes between tactical deployment (applying agents to known problems) and strategic deployment (hoping agents

On March 14, 2025, Albedo launched its first satellite, Clarity-1, aboard SpaceX Transporter-13, achieving significant milestones in satellite technology and operation. The mission aimed to validate innovative designs for Very Low Earth Orbit (VLEO), an area previously deemed impractical for standard satellites due to atmospheric drag and atomic oxygen erosion. Clarity-1 exceeded performance expectations, demonstrating a drag coefficient 12% better than target predictions and validating models projecting a five-year

The author reflects on their relationship with data and programming, likening their current exploration to interacting with an enigmatic mass of data that elicits varied responses based on different approaches. They share their background rooted in Ruby, a programming language associated with creativity and expression, influenced by the philosophy that code can be a medium akin to art rather than merely a tool for outputs. The author emphasizes a different mindset toward coding: viewing it as a space for thought and innovation rather than just a means to an end. Inspired

BirdyChat has announced a significant milestone as it becomes the first chat app in Europe to enable message exchange with WhatsApp under the Digital Markets Act (DMA). This feature, currently being rolled out by WhatsApp, will allow BirdyChat users in the European Economic Area (EEA) to initiate chats with any WhatsApp user using just their phone number, eliminating the previous requirement for both parties to have a BirdyChat account. This change aims to facilitate the adoption of BirdyChat for work

Oxide is a header-only library for C++ that integrates Rust's ownership semantics, safety features, and explicit mutability, aiming to enhance the safety, expressiveness, and clarity of C++ code. It operates under a strict discipline, enforced by the OxideValidator, a Clang-based tool that identifies and flags "unsafe" C++ code. The validator requires a compilation database (compile_commands.json) for operation, and there is also a VS Code extension (oxide-vscode) that provides

The article discusses the challenges Ruby developers face when using Claude Code due to the complexity of Ruby version managers (such as rbenv, chruby, and rvm), which can lead to test failures and difficulties with environment management. To address this issue, the author created a project called ruby-skills, designed to help Claude better understand the Ruby development environment. This project includes two main plugins: 1. **ruby-version-manager**: This plugin detects the Ruby version manager being used and the required

Epaper screens vary in type, primarily categorized as black and white, greyscale, or color. While newer panels often have greyscale and some color capabilities, they typically offer limited levels of detail compared to standard displays. For instance, some digital signage variants may include basic colors, whereas e-book readers may display a range of colors but with lower fidelity. The chosen panel for the project is a black and white model with 16 greyscale levels, selected for its availability and superior speed

In May 2025, the cURL project's bug bounty program faced an influx of irrelevant reports generated by AI, leading to frustration among maintainers. Despite warnings from creator Daniel Stenberg about banning individuals submitting poor-quality reports, the problem persisted. As of January 31, 2026, cURL will officially end its bug bounty program, though issues can still be reported via GitHub or the mailing list without financial compensation. This decision was prompted by an overwhelming number of submissions, the majority of

VectorWare has announced a significant development: Rust's standard library can now be utilized in GPU programming. This achievement allows developers to create complex, high-performance applications using familiar Rust abstractions, thereby harnessing the full potential of GPU hardware. The implementation integrates with Rust's layered standard library while maintaining compatibility with #![no_std], which is essential for environments like GPUs that lack traditional operating systems. As maintainers of the rust-cuda and rust-gpu projects, they facilitate the execution of Rust code

The text discusses the impact of Artificial Intelligence (AI) on the software development industry, questioning whether AI will replace human coders or simply augment them. The author critiques sensational claims, such as those from YouTube videos portraying a layperson as capable of quickly creating fully-functional apps using AI, arguing that these apps often lack the necessary robustness, security, and scalability. He emphasizes the importance of a deep understanding of software architecture for building reliable applications, something AI cannot genuinely grasp. The author expresses skepticism towards

In a recent incident involving OpenChaos, a GitHub repository where users submit pull requests (PRs) and the community votes on them, a malicious attempt was uncovered. @marcaddeo discovered Base64-obfuscated code in PR #8, which revealed the author's username (FelixLttks) and worked as a Trojan horse. Despite 218 votes supporting the PR, its hidden manipulation raised ethical concerns. The maintainer decided not to merge the PR, citing the presence of undisclosed manipulation
