New ask Hacker News story: Ask HN: AI Agent and harness containerization/security recommendations
Ask HN: AI Agent and harness containerization/security recommendations
2 by dv35z | 0 comments on Hacker News.
Hello HN crew - I am seeing the tendency for people to allow AI agents to access local project & user folders, and beyond (operating system files). I thought to ask the question: How can we best use AI tools safely - where the workflow often runs local system commands and network commands - to protect the integrity of our systems & data AND be easy enough to use productively? Comment structure idea: Operating system / Agent harness / Agent / Security strategy & tool stack / Workflow To give some examples: I am currently using OpenCode (+DeepSeek) on Linux Mint Debian Edition (LMDE), and I notice that the Agent & harness is frequently asking to create files in /tmp/ - I usually forbid this, and instruct it to only use files in the current folder. I would rather that the tool ONLY have access to a given project folder (~/Projects/PROJECT-NAME) in a system-enforced way. However, I see that the agent often wants to run system commands (like `ps` to debug a local dev server, `pandoc` or `ffmpeg` for file conversion, etc). This starts blurring the line - so I'm thinking that in order for the AI agent to be useful, I can consider giving it access to an isolated operating system - leading me to think about Virtual Machines, Docker containers, and so on. That introduces complexity like, "Should I be using shared folders between my system/VM?" etc. Would love to hear what's been working for you, the "ideal" state, and practically how we can implement it. I ought to mention that I'm frequently teaching technology (including AI) to somewhat newbies - so I am trying to find that balance, that lets them get easily something done effectively, but gives them security/integrity practices by default starting off, so they don't get into an awful jam ("The AI deleted my project/computer!"). Thanks!

You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 800 problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned.

Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go

Rate limiters and circuit breakers work wonderfully well when they’re configured for the load and available capacity. But load, capacity, and latency drift over time, and keeping those settings current requires continuous effort. So I built Levee to be a hands-off, adaptive, easy to configure traffic governor. Levee is configured with a success-rate target and timeout. It then continuously monitors the workload performance characteristics to detect downstream capacity exhaustion or failures. It can also spot a surge from growing concurrency before failures arrive. It runs in-process, uses a small, fixed amount of memory, has zero dependencies, and processes millions of requests per second. In a deterministic 10-node mesh simulation, Levee outscored carefully tuned static rate limiters/breakers deployed throughout the mesh, while recording fewer failures and no node crashes.

Ask HN: My father died and I need to find my path

It's been 38 days and 6 hours since my father passed away. I was let go from my internship during the last month we spent at the hospital. I went to the hospital in tears and poured my heart out to my father. He told me something I can still hear ringing in my ears: "If, when I took the university entrance exam, I had the opportunity to get into the best university in the country, believe me, I would study day and night to get in. I'd find some way, study hard, and get in. Your profession matters so much. Having a good profession is crucial for your family's comfort and future." Those words became a pearl earring in my ear. After saying this, he kept giving me advice to pull me away from the uncertain path I was on. And now he's gone. For the past two years, I've been studying electrical and electronics engineering in my country (Turkey), and this semester I noticed that my interest in computer engineering has surpassed everything else. So I've decided to transfer, and with God's permission, I'll be switching to computer engineering next year — but I still don't know how I should navigate this field. I don't know which technologies I should learn. There are times when I even wonder whether I should switch at all. My fears have started to grow that by the time I graduate, AI will have replaced everyone. [1] If my father were here, I'd ask him. He'd find the best path for me, and I'd trust that it was truly the best. But he's not here anymore, and I'm alone. Along with my family, we're carrying on with our lives. This summer, my father was going to find me an internship — that's what I kept telling myself. I had no worries at all back then, but right now I feel like I'm drifting in a void, and I need someone to show me a path. I thought maybe someone on this forum could point me in a direction. My father's words keep echoing in my ears, and I want to have a good profession, just like he said. Maybe you can help me. [1] https://ift.tt/BzgQUJa Text was translated from Turkish with GLM-5.2

Hey HN, This started as a personal curiosity and Claude helped me build it out. The Quiet Map reads 98 broadband seismometers from around the world every hour. Ground vibration in the 4–14 Hz band is usually done by human activity - traffic, trains, footsteps etc. Each station is compared against its own history at the same hour of day, and the map names the place currently furthest below its own normal: the quietest place on Earth right now. Hope you enjoy it and would love your feedback!
