Show HN: Levee – a self-tuning circuit breaker and concurrency limiter for Go
3 by code_martial | 0 comments on Hacker News.
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
4 by c4kar | 5 comments on Hacker News.
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!

i use claude code daily and measured what pages cost it while doing research. an average wikipedia article, for instance, is 68,240 tokens of raw html (tiktoken); nike's homepage is 353,000. claude code's built-in webfetch handles the easy case well. it summarizes wikipedia to about 950 tokens and clears cloudflare on some sites like indeed and ticketmaster. but, and there's always a but, on js-rendered and some anti-bot pages it returns nothing. quotes.toscrape.com/js gives "no quotes found"; nike.com gives a 403. your agent then dumps the raw html back into context and still fails. (note: i have also had cases where i read through the chat at the end and saw that it failed and just pulled from either training data or stale caches from other sources) so i worked on building an open-source stealth browser (recompiled chromium) that runs as an mcp for claude code, cursor, and claude desktop. essentially all i have to change form my end is add the mcp, and it returns the cleaned up tokens while also beating detection: the js quotes come back in 285 tokens, nike in about 700 instead of a 403. there is still stuff i am actively working on: there's no residential egress yet, and it won't beat kasada-style walls. it's for agents, qa, and research. repo and the reproducible benchmark: https://ift.tt/cVxHF1z i'm the author and here for feedback.

Show HN: SubjectiveZero, an open-source agentic node editor for creative coding

Hey there, My name is Clem, I've been a solo indie dev for a couple years now, exploring frontier tech like XR and agentic workflows in the context of creative / interactive work. I've been building creation tools for a while and some common design challenge is to figure out the right level of abstraction for your tool. You can always make it super advanced and complex with low level concepts (shader composition, actual code etc.) but then you get something with a high complexity / learning curve. On the other hand, if you make your tool too high level, it might be easier to use at first, but people will most likely hit a wall eventually and start fighting with your tool to get their edge case done (you see that on mobile a lot actually). With this prototype (called SubjectiveZero), I'd like to imagine that we can kind of move the "slider" on the abstraction layer, meaning that you can actually start with prompts that describe the goal, and you can go as high level (stay with abstract prompts) or low level as you'd like (more specific prompts, or even edit the generated code directly)! The agent orchestration actually understand your context and work along side with you to figure out what could be the best node graph structure for your project (that and some fun little procedural UI done at the node level). If i had to pitch it in 30 seconds, I'd say "Think TouchDesigner and friends but with agent orchestration". When you use it, it will generate real native code (Swift/Metal for now) that you can actually hot reload and iterate on either manually or through agents. It's still an early prototype and macOS only for now, but I'd love to get genuine feedback that could help me drive where this project should go next (or not). Lastly, I'm absolutely open and upfront on the fact that I used agentic coding for this, but as people say: "kept on a short leash". The architecture and specs were relatively well thought out and I personally prefer to be in the loop and review all the code being written to make sure it's going in the right direction. Oh and it's open source :-) Hope you like it! https://ift.tt/FRVTNaQ
