agent-replay provides time-travel debugging and side-by-side diffs to pinpoint exactly where AI agents hallucinate or fail. It replaces manual log diving with a local-first toolkit to replay, fork, and automatically evaluate agent traces for faster iteration. It's a work-in-progress. I'd love any feedback. Thank you.

The article discusses the creation of a simple blog platform using Python, Flask, and PostgreSQL. It covers the setup process, database integration, and the implementation of basic features like creating, reading, updating, and deleting blog posts.

I built Starts Club to help founders validate their startup ideas before building.

It uses structured validation methods inspired by Y Combinator, combined with real global market data, competitor analysis, and country-specific insights.

Since launching recently, 50+ founders have signed up organically and generated 100+ validation reports.

I’d love feedback from the HN community on the product, the reports, and how it can be improved.

The HistoMap is an interactive visualization tool that allows users to explore and understand the history of the world from 3000 BCE to the present day. It presents a comprehensive timeline of major civilizations, empires, and events that have shaped the global landscape.

Hey HN, Most fine-tuning loops waste a huge amount of compute by treating every sample equally every epoch — even the ones the model has already mastered. I built GEKO (Gradient-Efficient Knowledge Optimization) to fix that. It tracks per-sample confidence and correctness in real time and:

Completely skips samples the model has mastered Gives up to 5× more compute to hard/confidently-wrong samples Dynamically adjusts sample weights using a "Mountain Curriculum" Just dropped v0.3.0 with native LoRA/PEFT, BF16, gradient checkpointing, torch.compile, and 8-bit optimizer support. I'm currently building a clean UI for it. I'm a 17-year-old indie dev working on this. Would love honest feedback, especially from people who do a lot of fine-tuning.

The article explores the potential of local AI, where machine learning models are deployed and run on user devices instead of in the cloud. This approach offers benefits such as improved privacy, reduced latency, and offline functionality, making it a promising direction for the future of AI applications.

This article discusses the development of an AI system that can play blackjack at a high level, outperforming average human players. It details the machine learning techniques used to create the AI, its performance in various blackjack scenarios, and the potential implications of such advanced AI systems for the gaming industry.

c-mera is an open-source, portable digital camera software that provides a customizable user interface and supports a variety of image sensors and file formats. It is designed to be easily integrated into embedded systems and can be used for various applications, such as security, surveillance, and industrial imaging.

The article warns military members and veterans about a widespread scam targeting them, involving fraudulent offers of discounted or free services. It urges readers to be cautious of unsolicited offers and to verify the legitimacy of any service providers before engaging with them.

This article explores the concept of 'The March of Nines' - a phenomenon where certain numbers, particularly 9, appear to have a significant influence on various aspects of life, including finance, technology, and society. It delves into the historical and mathematical significance of the number 9 and its potential implications for understanding patterns and trends.

Claudini is a framework for creating secure microservice-based applications in Rust. It provides a set of tools and libraries to help developers build reliable, scalable, and maintainable microservices with a focus on security and performance.

The article discusses the potential benefits of integrating SSH keys into password management systems, allowing users to authenticate with their existing SSH keys instead of traditional passwords, improving security and convenience.

Tablesaw is an open-source data manipulation and analysis library for Java that provides a convenient and powerful way to work with tabular data. The library offers a range of features, including data loading, data transformation, and data visualization, making it a versatile tool for data-driven projects.

The article discusses the potential impact of robot armies on warfare, highlighting concerns about the ethical and legal implications of autonomous weapons systems and the need for international regulation to ensure responsible development and use of these technologies.

I’ve always found the concept of AI "hallucinations" fascinating. We constantly debate whether models are creative or just making stuff up, so I wanted to see what happens when you remove the guardrails entirely.

Tresbuchet is a publishing experiment. I drop a loose prompt into the agent along with a folder full of random text files, chat logs, and thoughts I’ve accumulated over the years. No specific instructions, no schema, no guidance on how to style it. I just tell it to "Go."

It reads the unstructured text and generates a completely new iteration of the site based on how it interprets the data.

It's been interesting tracking how different platforms (Claude, Codex, Gemini) handle the exact same mess of text differently. I've found that giving the models less instruction actually yields more interesting UI and copy results than trying to prompt-engineer a specific outcome.

I'm just building stuff to see what the models do when left to their own devices.

Curious what you guys think of the approach.

This article discusses the importance of crafting clear and intentional commit messages to better communicate the purpose and impact of code changes within a software development team. It emphasizes the value of using commit messages to document the context, reasoning, and potential implications of each commit.

Say hypothetically the productivity boost from AI is 2x per employee and a company has 10,000 employees.

Wouldn't number of employees be a huge point of leverage?

Why would you do a layoff when your 10,000 employees are now equivalent to 20,000

Aren't you technically in the best possible position for growth?

The article discusses the limitations of AI-generated writing and the ethical concerns around its use, arguing that AI-written content is easily identifiable and can undermine the trust and authenticity of written work.
