Ask HN: Am I being advertised an ARG via user agent logs?

I'm here looking through logs on my unnamed reverse proxy and CDN service. The crawler bot swarm has been hitting my PHP application like I've upset them so I'm seeing which weird user agent strings are being allowed to connect. There's "Sogou" and "meta-webindexer" and a small number of requests from "SleepBot/1.0" What's SleepBot? The ASN is Google and the UA string is: "Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; SleepBot/1.0; +http //sleepbot com/) Chrome/131.0.0.0 Safari/

Show HN: Run Agent Skills with mistral.rs v0.8.10: /v1/skills support and more

Hey all! I'm the maintainer of mistral.rs. I just landed support for OpenAI-compatible Agent Skills via a /v1/skills endpoint, and it works with local open models. Until now Skills have basically been locked to closed models, and with the ability to have private, local intelligence becoming increasingly important, but this feature allows you to do XYZ with local models. It's fully compatible with OpenAI's /v1/skills API, so you can drop mistral.rs into your existing code with minimal difficulty.

Epic Games Open-Sourced Lore — A Version Control System Built for Massive Game Assets

Epic Games just dropped something that could reshape how game studios handle code and assets. They've open-sourced Lore — a centralized version control system built from the ground up to solve one painful problem: managing enormous binary files alongside source code. This isn't another Git wrapper. It's a completely new VCS, written in Rust, MIT-licensed, and battle-tested behind Fortnite's UEFN (Unreal Editor for Fortnite) toolkit. Why Does the World Need Another VCS? Git is brilliant for text-based code. But game development isn't just text. It's 4K textures, uncompressed audio, rigged 3D models, animation sequences, and massive world maps. These files can be hundreds of megabytes each. Git wasn't designed for this. Git LFS (Large File Storage) helps, but it's a patch on top of a fundamentally text-oriented system. Perforce Helix Core has been the industry standard for game studios for decades — but it's proprietary, expensive, and closed-source. Epic Games looked at this landscape and said: we can do better. What Is Lore? Lore is a centralized, content-addressed version control system optimized for: Large binary assets — textures, meshes, audio, video Massive teams — hundreds of developers working simultaneously Hybrid projects — code + binaries in the same repository Sparse checkouts — developers only download what they need Think of it as Perforce's philosophy (centralized, binary-friendly) combined with Git's content-addressed storage model, wrapped in Rust's performance guarantees. How It Works Under the Hood Lore's architecture is built around a few key technical decisions: Content-Addressed Storage Every piece of data is stored and referenced by its content hash. This means: Automatic deduplication — identical content is stored once Integrity verification — any tampering changes the hash Efficient caching — content can be cached anywhere in the pipeline Merkle Trees & Immutable Revision Chain Revision hashes are cryptographically derived from parent hashes

Show HN: Local personal data redaction for any AI tools

I built the desktop app that detects and redacts personal data (or PII) locally without sending any text to server. It supports rule-based filtering and AI model-based redaction (eg openai privacy filter). It's open source and free. Please check out the repo and https://pii-gui.vercel.app/

Ask HN: Has anyone had success with SBIR grants and what is the process like?

I'm considering applying to a phase I topic that is a pretty good fit for our tech and we should meet all basic requirements (U S. Based, small business, etc.), but I'm unsure if the juice is worth the squeeze. If anyone has any experience applying and going through the process I'd love to hear about it. Things I'm curious about... - how competitive is it? - how detailed should proposals be? - am I guaranteed to hear back? - how long after closing is a decision made? Thanks in advance.
