I built a 4-tier self-healing runtime for AI agents running 24/7.

When the gateway goes down, it escalates: watchdog → HTTP health check → Claude Code "doctor" (reads logs, diagnoses, autonomously fixes) → Discord alert.

The interesting part: Claude Code is both the patient and the doctor. Open source, bash-only, macOS/Linux.

The article discusses a mobile nuclear reactor that can be packed into a C-17 Globemaster III military cargo plane, allowing for rapid deployment and providing power in remote locations or emergency situations.

This study suggests that the brain may prioritize learning from rare or unexpected events over repetitive experiences, challenging the conventional understanding that repetition is key to learning and memory formation.

A new study from the University of Heidelberg found that older dogs can learn new tasks just as effectively as younger dogs, challenging the common belief that it's difficult to teach older dogs new tricks. The research suggests that with the right training methods, dogs of all ages can acquire new skills and behaviors.

The article discusses the institutional consensus for the fourth quarter of 2025, analyzing where 'smart money' is converging. It examines the top stock picks and sector allocations among major institutional investors and provides insights into the overall market outlook for the upcoming period.

The article discusses the Minimal Contractual Protocol (MCP), a new transitional protocol that aims to provide a bridge between traditional and decentralized finance. MCP seeks to facilitate interoperability and enable the migration of assets and users between these two financial ecosystems.

This article explores the parallels between the current software industry and the Industrial Revolution, highlighting how technological advancements have transformed the creation and distribution of software, leading to a widespread disruption of traditional business models and the emergence of new opportunities.

This article explores the author's search for a Discord replacement, discussing the limitations of Discord and the potential for open-source alternatives that prioritize user privacy and control.

The article discusses a computer scientist's perspective on the concept of heaven, drawing parallels between the idea of heaven and the architecture of a microkernel-based operating system. It explores the potential for a minimalist, highly efficient and reliable 'heavenly' existence, drawing on principles of software engineering.

Hey HN,

When an AI agent makes a decision, it evaluates several options and picks one. The rest disappear forever – you never see what it almost did or why it rejected the alternatives.

I built GhostTrace to fix that. It captures "Phantom Branches": the actions your agent considered but rejected, with the reasoning for each rejection. All saved to a .ghost.json file you can replay and inspect.

Quick demo:

ghosttrace record Recorded 4 decisions with 5 phantom branches Saved to gt_a1b2c3d4.ghost.json

ghosttrace replay gt_ghost.json --show-phantoms

Step 1: read_file → src/auth.py REJECTED: write_file (premature) REJECTED: search_codebase (too broad)

pip install ghosttrace

PyPI: https://pypi.org/project/ghosttrace/

It's framework-agnostic for now, but what agent frameworks should I integrate first? LangChain? CrewAI? OpenAI Agents SDK?

Feedback very welcome!

This article discusses the implementation of a POSIX-compatible interface for UEFI firmware, allowing developers to write portable applications that can run on a variety of hardware platforms with UEFI firmware. It provides a framework for building cross-platform UEFI applications using the POSIX standard.

This tutorial explores techniques for building performant dashboards, including optimizing data fetching, leveraging caching, and implementing progressive rendering to deliver fast and responsive user experiences.

The article explores what happens when a user types a URL into a web browser, providing a detailed technical explanation of the complex process that occurs, from DNS lookup to the rendering of the web page.

The article discusses a new complexity theory that aims to better understand the behavior of quantum systems, which are notoriously difficult to predict and model due to their inherent complexity. The theory provides a framework for studying the computational power and limitations of quantum computers and may have implications for fields like cryptography and materials science.

The article discusses Google's Grok, a new notification system that aims to provide users with more relevant and personalized alerts. Grok leverages machine learning to understand user preferences and deliver notifications that are tailored to their interests and needs.

The article discusses the risks and challenges faced by settlers, such as disease, conflict with indigenous populations, and environmental hazards. It explores historical examples and provides insights into the difficulties of establishing new communities in unfamiliar territories.

The article explores a new AI-powered tool called Accent Oracle that helps users improve their accents and pronunciation. It provides personalized feedback and training to help users speak more clearly and confidently in a new language or accent.

Hey HN,

Recently built an Apple II emulator and at the same time was getting into Tiny Tapeout and decided it would be cool to build a cycle-accurate 6502 CPU and an MCU for it. It's cycle accurate and the core itself should be 100% compatible with a stock MOS 6502 (would need to still test this though!).

Tested on some FPGAs (fomu, ulx3s) and works great, hoping to get it taped out in the upcoming IHP26a shuttle.

Also as part of the project I built a bus multiplexer to allow memory/bus access from an RP2040 to work around the limited pin count on Tiny Tapeout. This let's you load up programs on RP2040 and the CPU can read/write from it.

Three months ago I posted a batch AI image tool here. I pivoted after noticing something odd with ecommerce clients.

AI agents were visiting their sites but not citing them.

The reason is structural. LLMs parse raw HTML and often skip JavaScript-rendered content. Reviews inside Yotpo or Judge.me widgets? Invisible. Product data buried in React? Frequently misread or skipped.

So you can rank well on Google and still barely exist in AI answers.

A few numbers that changed my view:

80% of URLs cited by ChatGPT do not rank in Google’s top 100 (Ahrefs)

ChatGPT referral traffic converts at 15.9% vs 1.76% for Google organic

AI referral traffic to US retail grew 4,700% YoY (Adobe, mid-2025)

We started building Mersel AI to address this. It adds a machine-readable layer on top of existing sites using structured data and server-side HTML. No visual changes. No redesign. We also write GEO-optimized content.

Early stage, a handful of paying brands, seeing 2 to 5x increases in AI citations in the first few weeks.

Curious if others here are seeing AI traffic behave differently from organic.

The article explores the Breach Chain, a cybersecurity framework that analyzes the different stages of a cyber attack and helps organizations develop comprehensive defense strategies. It highlights the importance of understanding the attack lifecycle to enhance overall security posture and resilience.

This article discusses how a startup built its entire infrastructure on FreeBSD, highlighting the benefits of the operating system such as stability, security, and ease of management in a production environment.

The article provides an overview of pg_ash, a PostgreSQL extension that collects and analyzes system activity data, enabling improved performance monitoring and troubleshooting for PostgreSQL databases.

The article discusses the challenges of deploying large language models, focusing on the significant computational resources and energy required to run inference on these models. It explores strategies to reduce the inference cost, such as model compression and hardware acceleration, as well as the trade-offs between model performance and deployment efficiency.

The study investigates how the global COVID-19 pandemic has impacted the mental health of healthcare workers, finding significant increases in anxiety, depression, and burnout, especially among younger and female healthcare professionals. The results highlight the need for targeted mental health interventions and support systems to address the ongoing psychological challenges faced by healthcare workers during public health crises.
