[DevOps] Show HN: Envirobly – Efficient App Hosting This is my, fully bootstrapped, take on an application hosting platform. I designed it primarily for myself, to meet the following goals:<p>* Utilize the best parts of the cloud, leave expensive value added services behind. * Host anywhere in the world, close to your users. * Batteries included: backups, logging, monitoring, auto-scaling, containerization, databases. * Simple and user friendly.<p>The journey was tough. It took me round about 3 years to get everything just right. This goes against the conventional wisdom of getting something simple out quick. With a hosting platform however, in my mind, reliability, stability and certain maturity are a must have from the start.<p>I definitely need to work on the presentation, it&#x27;s barely covering the basics. But you have to start somewhere :-)<p>I&#x27;d love to hear some critique from the community. Thanks!

[DevOps] Show HN: Volant– spin up real microVMs in 10 seconds(Docker images or initramfs) I’ve been building Volant, a modular microVM orchestration engine that makes running microVMs feel as simple as Docker.<p>It supports cloud-init, GPU&#x2F;VFIO passthrough (yes, you can run AI&#x2F;ML workloads in isolated microVMs), booting Docker images via a plugin system, and Kubernetes-style deployments with replication, all from a single CLI(soon to be web UI, see next)<p>Coming soon: a built-in PaaS mode with snapshot-based cold start elimination, sort of like Dokploy, but designed for serverless workloads that boot from memory snapshots instead of containers.<p>Volant is intentionally a bit opinionated to make microVMs more accessible, but it’s fully extensible for power users.<p>Check out the README and the docs for more details.<p>It’s free and open source (under BSL), would love to hear feedback or thoughts from anyone!<p>tl;dr: 6-second GIF in the README shows the full flow: install → create VM → get HTTP 200.

[CLI Tool] Show HN: DidMySettingsChange – A tool that checks changed windows settings Microsoft has been under heavy scrutiny with how they manage Windows over the years, particularly concerning privacy and telemetry settings. Many users find that after disabling certain settings, these settings are mysteriously re-enabled after updates or without any apparent reason. DidMySettingsChange is a Python script designed to help users keep track of their Windows privacy and telemetry settings, ensuring that they stay in control of their privacy without the hassle of manually checking each setting. Features<p><pre><code> Comprehensive Checks: Automatically scans all known Windows privacy and telemetry settings. Change Detection: Alerts users if any settings have been changed from their preferred state. Customizable Configuration: Allows users to specify which settings to monitor. Easy to Use: Simple command-line interface that provides clear and concise output. Logs and Reports: Generates detailed logs and reports for auditing and troubleshooting.</code></pre>

[CLI Tool] Show HN: ut – Rust based CLI utilities for devs and IT Hey HN,<p>I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging. So, I built a toolkit with a sane and simple CLI interface for most of those tools.<p>For the curious and lazy, at the moment, ut has tools for,<p>- Encoding: base64 (encode, decode), url (encode, decode)<p>- Hashing: md5, sha1, sha224, sha256, sha384, sha512<p>- Data Generation: uuid (v1, v3, v4, v5), token, lorem, random<p>- Text Processing: case (lower, upper, camel, title, constant, header, sentence, snake), pretty-print, diff<p>- Development Tools: calc, json (builder), regex, datetime<p>- Web &amp; Network: http (status), serve, qr<p>- Color &amp; Design: color (convert)<p>- Reference: unicode<p>For full disclosure, parts of the toolkit were built with Claude Code (I wanted to use this as an opportunity to play with it more). Feel free to open feature requests and&#x2F;or contribute.

[Other] Show HN: A Vectorless LLM-Native Document Index Method The word &quot;index&quot; originally came from how humans retrieve info: book indexes and tables of contents that guide us to the right place in documents.<p>Computers later borrowed the term for data structures: e.g., B-trees, hash tables, and more recently, vector indexes. They are highly efficient for machines; but abstract and unnatural: not something a human, or an LLM, can understand and directly use as a reasoning aid. This creates a gap between how indexes work for computers and how they should work for models that reason like humans.<p>PageIndex is a new step that &quot;looks back to move forward&quot;. It revives the original, human-oriented idea of an index and adapts it for LLMs. Now the index itself (PageIndex) lives inside the LLM&#x27;s context window: the model sees a hierarchical table-of-contents tree and reasons its way down to the right span, much like a person would retrieve information using a book&#x27;s index.<p>PageIndex MCP shows how this works in practice: it runs as a MCP server, exposing a document&#x27;s structure directly to LLMs&#x2F;Agents. This means platforms like Claude, Cursor, or any MCP-enabled agent or LLM can navigate the index themselves and reason their way through documents, not with vectors&#x2F;chunking, but in a human-like, reasoning-based way.

[Code Quality] Show HN: Pyscn – Python code quality analyzer for vibe coders Hi HN! I built pyscn for Python developers in the vibe coding era. If you&#x27;re using Cursor, Claude, or ChatGPT to ship Python code fast, you know the feeling: features work, tests pass, but the codebase feels... messy.<p>Common vibe coding artifacts:<p>• Code duplication (from copy-pasted snippets)<p>• Dead code from quick iterations<p>• Over-engineered solutions for simple problems<p>• Inconsistent patterns across modules<p>pyscn performs structural analysis:<p>• APTED tree edit distance + LSH<p>• Control-Flow Graph (CFG) analysis<p>• Coupling Between Objects (CBO)<p>• Cyclomatic Complexity<p>Try it without installation:<p><pre><code> uvx pyscn analyze . # Using uv (fastest) pipx run pyscn analyze . # Using pipx (Or install: pip install pyscn) </code></pre> Built with Go + tree-sitter. Happy to dive into the implementation details!
