DDoS detection in 500 lines of Python (MIT, no cloud, no account)

What it does

Real-time DDoS traffic monitor. Single file. No account. No cloud. Drop it on any Linux server and see packets per second, bandwidth, protocol breakdown, source IP cardinality, and attack severity in real time. Pipe JSON to your own tooling or watch the live dashboard in your terminal. For a full TUI dashboard with real-time charts and sparklines, see NetHawk . pip install ftagent-lite[full] sudo ftagent-lite The [full] extra pulls in scapy (packet capture and protocol parsing) and psutil (fallback counters). curl -O https://raw.githubusercontent.com/Flowtriq/ftagent-lite/main/ftagent_lite.py pip install scapy psutil sudo python3 ftagent_lite.py Root / sudo is required for raw socket…from github.com

  An open source access logs analytics script to block bot attacks2025 · github.com · ▲37

  This is a small PoC Python project for web server access logs analyzing to classify and dynamically block bad bots, such as L7 (application-level) DDoS bots, web scrappers and so on. We'll be happy to gather initial feedback on usability and features, especialy from people having good or bad experience wit bots. *Requirements* The analyzer relies on 3 Tempesta FW specific features which you still can get with other HTTP servers or accelerators: 1. JA5 client fingerprinting (https://tempesta-tech.com/knowledge-base/Traffic-Filtering-b...). This is a HTTP and TLS layers…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
