[Other] Show HN: Enter your domain and my open-source agent will hack it I built an open-source AI agent for security testing to find and fix vulnerabilities in your code.<p>I’ve noticed how bad security vulnerabilities have gotten with everyone shipping AI code slop, so I wanted to build something that allows for vibe-coding at full speed without compromising security.<p>Traditional security tools aren’t effective, and manual pen-testing can’t keep up with the rapidly growing AI code<p>This tool runs your code dynamically, finds vulnerabilities, and validates them through actual exploitation.<p>You can either run it against your codebase or enter your (or someone else’s) domain to scan for vulnerabilities.<p>Good luck, have fun, hack responsibly!

[Other] Show HN: Real-time privacy protection for smart glasses I built a live video privacy filter that helps smart glasses app developers handle privacy automatically.<p>How it works: You can replace a raw camera feed with the filtered stream in your app. The filter processes a live video stream, applies privacy protections, and outputs a privacy-compliant stream in real time. You can use this processed stream for AI apps, social apps, or anything else.<p>Features: Currently, the filter blurs all faces except those who have given consent. Consent can be granted verbally by saying something like &quot;I consent to be captured&quot; to the camera. I&#x27;ll be adding more features, such as detecting and redacting other private information, speech anonymization, and automatic video shut-off in certain locations or situations.<p>Why I built it: While developing an always-on AI assistant&#x2F;memory for glasses, I realized privacy concerns would be a critical problem, for both bystanders and the wearer. Addressing this involves complex issues like GDPR, CCPA, data deletion requests, and consent management, so I built this privacy layer first for myself and other developers.<p>Reference app: There&#x27;s a sample app (.&#x2F;examples&#x2F;rewind&#x2F;) that uses the filter. The demo video is in the README, please check it out! The app shows the current camera stream and past recordings, both privacy-protected, and will include AI features using the recordings.<p>Tech: Runs offline on a laptop. Built with FFmpeg (stream decode&#x2F;encode), OpenCV (face recognition&#x2F;blurring), Faster Whisper (voice transcription), and Phi-3.1 Mini (LLM for transcription analysis).<p>I&#x27;d love feedback and ideas for tackling the privacy challenges in wearable camera apps!

[Other] Show HN: ServerBuddy – GUI SSH client for managing Linux servers from macOS Hi HN,<p>I&#x27;ve built an app for macOS that allows performing common SSH operations on Linux servers using a native GUI.<p>The problem:<p>Managing multiple Linux servers usually means juggling terminal windows and copy-pasting snippets&#x2F;scripts. After dealing with tens of production&#x2F;staging VPSes at previous jobs, I realized there had to be a better way for common operations I did on a daily basis than my collection of bash snippets.<p>Features:<p>- Quickly switch between different servers. Tag servers with arbitrary key values for easy search.<p>- Real-time dashboard with CPU&#x2F;memory graphs, disk usage, and uptime.<p>- Table based interface for processes (sortable&#x2F;filterable), Docker containers, systemd services, network ports, and system logs etc.<p>- Built-in file browser.<p>- Full-featured terminal when you need to drop to the command line.<p>You can check out the screenshots at <a href="https:&#x2F;&#x2F;serverbuddy.app&#x2F;screenshots" rel="nofollow">https:&#x2F;&#x2F;serverbuddy.app&#x2F;screenshots</a> for a quick overview of the features supported.<p>All the above are done through SSH, there are no agents&#x2F;scripts to install on your servers.<p>From using the app for a few weeks(admittedly a short duration), I can say I much prefer the ServerBuddy based workflow to my previous workflows.<p>Pricing:<p>Free forever for one server, $59 one-time for unlimited servers (includes 1 year of updates).<p>If you&#x27;re a developer or sysadmin managing Linux servers from Mac, please do try out the app. I&#x27;d love your feedback regarding additional features&#x2F;workflows etc.<p>Thank you!

[Other] Show HN: An open-source email archiver with full-text search capabilities Hey HN,<p>I’d like to share an open-source project I’ve created. It is an email archiving tool that can back up your whole email system with full-text search capabilities.<p>The project is called Open Archiver, and it is able to archive and index emails from cloud-based email inboxes, including Google Workspace, Microsoft 365, and any IMAP-enabled email inbox. You can connect it to your email provider, and it copies every single incoming and outgoing email into a secure archive that you control (Your local storage or S3-compatible storage).<p>Some features:<p>- Archive and index all emails and attachments<p>- Import and sync the whole organization&#x27;s emails: For Google Workspace and MS 365, Open Archiver can ingest all individual inboxes&#x27; emails<p>- PST and .eml files import<p>- Role-based access<p>- Full-text search: All archived emails and attachments are indexed, so you can search the content of all emails and attachments<p>- You can choose to store your files either on your local machine or on any S3-compatible storage provider<p>- API access<p>It&#x27;s AGPL-3.0 licensed and free to use for personal and business purposes. I&#x27;d be happy if you could give it a try and give me some feedback.<p>You can find the project on GitHub (with Demo site): <a href="https:&#x2F;&#x2F;github.com&#x2F;LogicLabs-OU&#x2F;OpenArchiver" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;LogicLabs-OU&#x2F;OpenArchiver</a>

[Other] Show HN: I integrated Ollama into Excel to run local LLMs I built an Excel add-in that connects to Ollama, so you can run local LLMs like Llama3 directly inside Excel. I call it XLlama.<p>You can use it like a regular formula: =XLlamaPrompt(&quot;Is Excel a database&quot;) or run it on an entire range.<p>No API calls. No cloud. No subscriptions. Everything runs locally.<p>It’s useful for quick tasks like extracting names, emails, or phone numbers from text, or for doing light data analysis without leaving Excel.<p>Would love feedback, especially from people who use Excel daily.

[Other] Show HN: Bolt – A super-fast, statically-typed scripting language written in C I&#x27;ve built many interpreters over the years, and Bolt represents my attempt at building the scripting language I always wanted. This is the first public release, 0.1.0!<p>I&#x27;ve felt like most embedded languages have been moving towards safety and typing over years, with things like Python type hints, the explosive popularity of typescript, and even typing in Luau, which powers one of the largest scripted evironments in the world.<p>Bolt attempts to harness this directly in the lagnauge rather than as a preprocessing step, and reap benefits in terms of both safety and performance.<p>I intend to be publishing toys and examples of applications embedding Bolt over the coming few weeks, but be sure to check out the examples and the programming guide in the repo if you&#x27;re interested!

[Other] Show HN: Engineering.fyi – Search across tech engineering blogs in one place I built a search engine for engineering blogs because I was tired of manually checking individual company blogs to find real-world production examples.<p>The problem: When learning a new technology, the best insights often come from how companies like Google, Meta, or Stripe actually implement it in production. But these gems are scattered across dozens of separate engineering blogs with no way to search across them.<p>What I built: Engineering.fyi indexes engineering blogs from ~15 companies (Google, Meta, OpenAI, Anthropic, Stripe, Uber, etc.) and makes them searchable in one place. You can filter by topic, difficulty level, and whether articles include code samples.<p>Technical details: - Built with Next.js, SQLite, DrizzleORM - Custom scrapers for each blog (they&#x27;re all frustratingly different) - Basic tagging system using content matching (still improving this)<p>Current status: Core search is working. Adding new blogs weekly as I index them.<p>Next features (based on early feedback): - AI summaries for quick article previews - Weekly digest of trending engineering insights - Save&#x2F;bookmark articles (considering whether to add accounts)<p>Interesting challenges: - Each blog requires custom parsing logic (no standard format) - Building an accurate tagging system is harder than expected – started with exact matching but exploring better approaches<p>I&#x27;d love feedback on: - Which company engineering blogs you&#x27;d find most valuable to include - Whether AI summaries would actually be useful or just noise - How you currently discover engineering articles from these companies
