Show HN: Penthera, offline pentest security scanner (open-source, rule-based)

local non-AI security for your app/site! For years I had a long .txt file with hundreds of manual security checks I ran before pushing a (client) app/site to live; I am really a rookie compared to the real cyber experts, but just covering the basics has saved us many times from malicious attacks on our infrastructure. With the sprawl of AI generated vibecoded apps (I love it, i think creating should be accessible, but so should be cyber safety) and AI coding tools, our code goes to LLM providers

[分享发现] [分享创造] send-to-dot 0.3.0 预览版： dot 自己取原图发进原对话

Send to dot 0.3.0 预览版发布 Send to dot 是一个开源小工具：在 Android 或 iPhone 上分享一张照片，原图会直接出现在你正在用的 ChatGPT dot 对话里，dot 再接着回答你附带的问题。不用每次新开聊天，也不会把图压缩成预览图。 这次更新的重点： 🖼️ dot 自己取原图并发到对话：一次调用就完成领取和去重，原图通过 2 分钟有效、只能用一次的链接下载。 ☁️ 可选 Cloudflare R2 预存：上传时原图就先放到你自己的私有存储桶里，dot 来取时已经准备好，发完自动删除。 📚 连续多张一次处理：dot 会接着处理下一张，最后一次性记录，不用每张重新唤醒。 🛡️ 不确定就不重发：发送结果不确定时先停下、先核实，只有凭真实凭据才能解除，已经发出的图绝不会再发一次。 🔍 新增连接状态检查和更完整的审计日志，方便排查问题。 新功能默认关闭，老用户升级后没有任何变化；快捷指令和安卓页面也不变。 实测：从上传到图片发进对话，单张大约 45 秒，连发时每多一张约加 20 秒。主要时间花在 dot 被唤醒和平台调用上。我们原本的目标是

Show HN: Spaceguesser – GeoGuessr for the Solar System

GeoGuessr is really fun, and NASA publishes about 14k panoramas taken from the surface of Mars, so I wanted to see if it works in space. Half the rounds are these panoramas. Most come from the navigation cameras of NASA’s Mars rovers (Spirit, Opportunity, Curiosity, Perseverance), but many other probes are also in. The other half are orbital views from my map of the solar system, https://spacemap.co (Svelte + Three.js). The maps are all available as an npm package (spacemap). I’ve got a few game

Show HN: FicScout – Like Goodreads, but see books rated by characters, plot etc.

Hey HN, I’m Jake. I know this isn't for work or AI tool like most other products on here, but hopefully this will bring some joy and adventure to your personal life. I used to spend hours combing Goodreads and Reddit to see if I’d actually like a book before I commit to buying it and reading it. A single number for the rating, like 4.37 stars, wasn’t really helpful because everybody values different things (characters, plot, writing, etc). And the reviews were most helpful, but reading them all

Show HN: Waymark – A workflow engine that compiles jobs instead of replaying

Hey everyone! @mozgiii and I have been working on Waymark for the better part of the last year. Waymark’s an open source durable execution library with similar functionality to Temporal or DBOS. I fell in love with durable execution a few years ago, after working at a company with a heavy pubsub architecture. In comparison to job orchestrators that force a certain task design or special syntax, many of these durable libs lets you write business logic in regular code: `asyncio.gather` to parallel

[程序员] 发布了一门新的课程 AI Agent 工程实践，感谢大家的支持

《 AI Agent 工程实践：从心智跃迁到生产部署》 28 讲系统课程发布 大模型时代的工程师分水岭： 别人还在写提示词问答，你已经能驾驭由 LLM 自主决策控制流的工业级 Agent 系统。 💡 为什么你需要这门课程？ 2024~2026 年，大模型应用开发发生了一次关键心智跃迁： 从单一对话的 Chatbot ，走向拥有双手、记忆、规划与协作能力的 AI Agent （智能体）。 但是，许多开发者在尝试把 Agent 搬上生产环境时，都会撞上同一堵墙： ❌ 难以控制 ：模型调用外部工具频频格式出错、死循环； ❌ 状态失控 ：多轮对话上下文越来越臃肿，记忆容易遗忘关键信息； ❌ 上线不敢用 ：缺乏可观测追踪（ Tracing ），一旦报错无从排查，还面临 Prompt 注入攻击的风险。 把 Agent 从 Demo 变成工业级产品 ，需要一套扎实严谨的 工程学科体系 。 为此，我们倾力打造了这套 《 AI Agent 工程系统学习课程》 —— 28 节深度大课、11 大核心模块、覆盖 4 条定制化学习路径 ，带你从底层 ReAct 推理循环，一路杀到企业级长任务工作流与加密审计！

Show HN: Synaps – Turn your agents into autonomous daemons

Waddup gangsters. I was browsing reddit, and I saw anthropic add a rule to claude code preventing people from making their own games. Users don't even have an option to turn that off. It's nuts if you ask me. You should be able to control 100% of what get's sent to the LLM. I also didn't like the slow and bloated harnesses written in typescript, so I decided to build a better claude code. For the past 6 months, I've been working on it and making it better, to the point where it absolutely smokes

Show HN: Strive and Seek – original merch for builders, hackers and founders

It all started with a poster in our office that says "F ck it, ship it". People really gravitate to the poster. Take pictures with it. Tell us, "we love the sentiment!" So we decided: why not launch a shop? Strive & Seek is a side project with our own designs for builders, hackers, founders, etc. Some designs are more upbeat. Others lean into the more realistic challenges of building things: "Born to Code, Forced to Fundraise" is an example. We shouldn't pretend

Show HN: Ferry, a highly customizable and feature-rich file manager for macOS

I am the main developer of Ferry. The team I am part of began on the demoscene in the mid-90s, but for a long while we are mainly just an indie development studio. Ferry started with me being forced to use macOS at my current workplace, which suddenly replaced a working environment I'd been using during professional career as a programmer: Windows for around 10 years, then Debian/KDE for the last 15 years. Over that time, I'd grown very accustomed to Total Commander on Windows, and later Dolphin
