2. Show HN: JUring – Java bindings for io_uring file I/O
URL: https://github.com/davidtos/JUring
Author: davidtos
Description: Hi HN! For the past few weeks, I've been working on bringing io_uring to Java. It started as an experiment, but slowly it became more than just that, and now trying to turn it into a proper library.
After hearing talks about virtual threads and io_urings performance I wanted to build something that was faster than Java provides out of the box.
I ended up creating two APIs:
- A direct one that closely mirrors io_uring's behavior
- A blocking one built with Virtual Threads in mind for remote files.
This is the link to the project if you are interested https://github.com/davidtos/JUring
It's still far from done, but it's running! Would love to hear your thoughts if you've worked on or used something similar. Also very curious to hear what you like and don't like about the project!

3. Show HN: Finding good value property
Author: timothyxyang
Description: I built this product last year when my parents found a unit with 1.3m land value for sale for 825k. Similar properties have already sold for land value in the area when the whole block was sold to developers. This tool is to find these opportunities in bulk, without tediously looking at real estate listings one by one and using slow clunky government land value search tools.
Did you know? Astute property buyers compare the sales guide of a property with the land value. The unimproved land value without buildings is assessed by the government. This is often significantly lower than the sales guide. We help you find properties currently on the market which have good investment opportunity. Get started now, use our search below. Currently serving NSW, ACT and QLD.
Was thinking about rolling this out globally once I have enough traction in Australia, as this is applicable in USA, Canada, UK, New Zealand etc.

4. Show HN: Moneta – Conversation as the Engine of Application State
URL: #
Author: rintrah
Description: Hi HN! I’m Thunder. Longtime lurker and first time poster. I’m excited to present Moneta (https://moneta.studio/) with my co-founder Rob.
Moneta is a conversation-as-code platform for building multiplayer AI-native applications in which the AI can reactively update the application based on interactions with users or other AI via CRDTs.
The key idea is that rather than using a conversation to generate an application, in Moneta the conversation is the application. We call this idea 'conversation as the engine of application state' (CATEOAS).
This means that instead of saying “create a todo list that can do X, Y, and Z” you would instead be declarative and say in the conversation “please add x to my todo list”. The conversation serves both as a universal interface and the engine of state.
The state itself is managed via Yjs - we treat the AI and the users as collaborators on a shared Yjs document per each application.
Finally, every Moneta application is equipped with the ability to dynamically fetch its own hypermedia or the hypermedia of other applications (both Moneta and otherwise) as well as post messages to itself or other applications (assuming it has the correct access privileges). This means that it can introspect, self-message and communicate with other Moneta applications as well as external APIs both via the conversation as well as the UI.
Moneta and the concept of CATEOAS has continued to surprise us with emergent capabilities and I hope it will surprise you too. ---
As an example of Moneta in the wild, take a look at our Moneta generated landing page and note the multiplayer capabilities in the form of shared cursors and live user-count: https://moneta.studio/
NOTE: You can see the conversation for all Moneta apps by clicking the M tab on the right side of the page
Here’s Moneta’s take on Moneta and CATEOAS: https://thunder-hn-post-content.mnta.io/
Again note how Moneta can interact with comments in the UI or via the conversation.
And just for fun, here is a hacker news clone: https://thunder-multiplayer-hn.mnta.io/
Feel free to add comments in the above apps as well as review the conversations that generated it.
Please feel free to reach out at thunder (at) moneta dot studio.

7. Show HN: Panopticon AI – Open-source platform for military AI research
URL: https://github.com/Panopticon-AI-team/panopticon
Author: lukechen26
Description: Hi HN,
I’m sharing a project I’ve been working on: Panopticon AI, an open-source platform designed for researchers in military modeling and simulations. It’s web-based, integrates with OpenAI Gym, and is intended to support advancements in military AI through realistic simulations, wargaming, and reinforcement learning.
The project is still under active development, and I’m looking for contributors to help shape its direction. It’s released under the Apache 2.0 license, so anyone can use, modify, or contribute to it.
What Panopticon AI Offers:
- A simulation environment that is browser-based for creating and editing scenarios.
- Runs on Python to support training agents.
- Utilizes Stable Baselines for reinforcement learning.
- Basic data included, with a focus on Air Force scenarios.
Why I Built This: There’s a lack of open-source tools tailored for military AI research, and many existing solutions are proprietary or inaccessible. My goal is to lower the barrier for academics, researchers, and smaller organizations to explore this space and innovate.
How You Can Help:
- Try out the platform and share your feedback or ideas for improvement.
- Contribute to the codebase or documentation on GitHub.
- Suggest or help implement new features and use cases.
If this aligns with your interests, check out the links above or comment below. I’d love to hear your thoughts and see how we can make this project even better together!

18. Show HN: Cadence – convert any long form content into byte-sized texts
URL: https://www.getcadence.fyi/
Author: Hamza-Mos
Description: Hey HN,
I am a CS junior at the University of Waterloo, and like many other students my age, I struggle with attention deficit (aka "TikTok brain").
This applies to anyone with a busy schedule though. Ever left a tab open for weeks because "I'll read it later"? Or maybe there's a podcast you can't commit to because it’s too long, or a research paper you read ages ago but can’t remember the details?
Over the past week, I’ve been heads-down building Cadence, a tool that turns those long-form pieces of content—PDFs, YouTube videos, articles, podcasts, and more—into short, digestible text messages sent directly to your inbox.
Here’s why I built it:
- I have a classic case of "TikTok brain" and struggle with long-form content.
- I wanted something to help me keep learning or revisiting important info without sacrificing hours of my day.
- And let’s face it, we all have tabs that we swear we’ll get back to… someday.
Cadence is perfect for people with short attention spans (like me) or anyone with a busy schedule who still wants to learn and stay on top of things.
Try Cadence here: https://getcadence.fyi
Would love your feedback! I’m here to answer questions and talk about the tech behind it.
What do you think? Could Cadence help you finally close some of those tabs?

19. Show HN: I've built a WordPress plugin to generate LLMs.txt
URL: https://www.aeomatic.com/en
Author: pedrooladeira
Description: Hey HN!
I'm Pedro, and I’ve built the LLMs.txt Generator (https://www.aeomatic.com), a WordPress plugin that automates the creation and management of /llms.txt files, helping your website become an essential resource for AI tools.
Why does this matter? If you’ve experienced any of the following, this tool is for you:
1. Your website isn’t being recognized by AI tools like ChatGPT, Gemini, and others.
2. You know AI integration is important, but the technical steps feel overwhelming.
3. You’re missing out on traffic because AI tools can’t accurately index your content.
With LLMs.txt Generator, you can bridge the gap between your site and the rapidly growing AI ecosystem—quickly and effortlessly.
I’d love to hear your feedback or answer any questions you have. Whether you think this is a good idea, have suggestions for improvements, or want to share your own experiences, let’s discuss!
Thanks for checking it out! :)

21. Show HN: Cached GitHub Action Runners for Fast Builds
Author: afarchy
Description: Hey HN! We built a system to manage fully cached GitHub Action runners to speed up incremental build times substantially.
How it works:
Your user or organization gets dedicated GitHub Action runners. These are never destroyed until you request it—hence fully cached.
This lets incremental build times go as fast like they do on your local machine: Install software once, clone the repo once, make the first build, then make incremental builds.
This is particularly well suited for:
- Large codebases
- Game development (We use this for our own Unity game development)
- Custom dependencies or license requirements
Other tidbits:
- The runners have the same software as GitHub runners installed and use similar Azure VMs.
- Windows and Ubuntu supported.
- There's a trial version, and we're having a new year discount!
Thanks in advance for your feedback!

Description: Had a 2-week assignment in my Covert Channels class to make a new concert channel and settled on making one using the QUIC protocol by embedding encrypted payloads in the Connection ID field. Was honored to have the talk accepted at ShmooCon 2025. Link is a time referenced YouTube link for the Build It track talks (a lot of other good talks in there too). Welcome comments and critiques; opened plenty of my own in GitHub issues on the project page. Basically a proof of concept (completed for a 2 week deadline) so plenty of room for improvement in the concept as a whole.

URL: https://apps.apple.com/us/app/cont%C3%A9-create-tales-like-magic/id6475767265
Author: yurimhln
Description: My dad used to tell my brother and me the most amazing bedtime stories. Those stories live only in my memory now. I wished I had them preserved — not just in my head, but as something I could hold, that could sit on a shelf in my living room.
Now that I’m a dad myself, I wanted to do the same for my kids: turn those fleeting bedtime stories into something more tangible. So, I built Conté. An iOS app that helps parents turn the stories they tell into beautifully illustrated children’s books, almost as good as if they were made by professional authors.
The Hard Part: Crafting Consistent, Illustrated Stories with AI Anyone who's played around with AI-generated stories or images knows the struggle: AI can write, but the narratives often feel flat. AI can illustrate, but maintaining consistent characters across pages is a nightmare. This was our challenge. The hardest part wasn’t generating stories — it was making them feel real. Conté had to create coherent narratives, meaningful dialogues, and most importantly, consistent characters and style throughout the entire book.
It took a while, but we made it work. Test it out and tell me what you think!
What Conté Does
- iOS app (no Android yet — sorry!)
- No sign-up required. Just download the app and start creating.
- Create unlimited books for free.
- Buy a printed version if you want something physical to keep forever.
- Safe for kids: We have content moderation and a kids’ gate to keep the experience family-friendly.

Description: Are you losing track of all the repos you have? I am.
Have you used Github Actions to automate everything in existence? I have.
So I built a tool to generate a page full of Github Action badges.
And, of course, it runs as a Github Action! Or from as a CLI if that’s your thing.
It works really well for Github organization profiles: public or private.
Note that badges for private Github repos are only visible if the page is hosted on github.com (for security reasons), so if you want to use it on private repos, you should host the output on github.com: a Github profile or in a custom README file or a wiki...

URL: https://github.com/tbrugere/autocommit
Author: nephanth
Description: A personal project I made over the holidays.
Makes API calls to Codestral [1] using the diff and some simple RAG to pre-generate the commit messages.
It hooks itself to the git prepare-commit-message hook, so it just populates your commit messages automatically.
It helps get me started writing an actual commit message — even when it hallucinates, I have an easier time correcting a wrong commit message than writing one from scratch.
Would love some feedback, especially on the prompting: It tends to hallucinate, especially if there are relatively few changes.

37. Show HN: ZeroEntropy (YC W25), Advanced AI Search over Complex Documents
URL: https://dashboard.zeroentropy.dev
Author: ghita_
Description: Hey there YC!
We’re Ghita and Nicholas, the founders of ZeroEntropy.
We are on a mission to build the world’s most accurate search engine over complex and unstructured documents, behind a simple API.
If you are building RAG, a search bar, or search tools for your AI Agents, please reach out to us here founders@zeroentropy.dev
Why Most AI products - whether Q&A bots or AI agents - depend on retrieval systems to provide relevant context from knowledge bases.
Yet, the vast majority of these systems rely on basic semantic or hybrid search methods, which still frequently fail.
These mistakes lead to inaccurate responses and hallucinations by LLMs, frustrating developers and end users alike.
That’s why we’re building ZeroEntropy: to add intelligence to retrieval, and empower developers to build reliable and accurate AI products!
A few common failure modes The most common examples are:
- Negated Queries, like: “Which electric vehicle articles do not include any reference to Elon Musk?”.
- Multi-Hop Queries, like:“Where was the suspect who was identified in the report born?”
- Fuzzy Filtering Queries, like: “What diagnostic methods are suggested for early-stage cancer, in papers that mention a sample size of over 2000?”
These types of queries are common in industries like legal, healthcare and manufacturing, where documents are very complex. Semantic similarity and keyword-based approach fail on all these examples.
Our Solution Search AI agents can solve these complex queries. Not only can they understand the user’s intent, but also route each query to the most suitable retrieval system, ensuring precise and relevant answers. Moreover, they adapt and personalize their performance over time, continuously improving with use.
All of this capability is accessible through a simple API that you can try out at: dashboard.zeroentropy.dev.
About us We both have a background in math and AI: Ghita has two masters in Applied Maths from Ecole Polytechnique (Paris) and from UC Berkeley, and Nicholas grew up doing math and coding competitions at CMU before becoming the CTO of several startups.
We’ve both experienced the pain of building great retrieval systems from working as AI engineers and researchers in several industries from healthcare, to finance, to B2B SaaS, and consumer AI.
PS/Fun Fact In case you’re curious about our name, in information retrieval, entropy refers to the expected variability of information contained in a variable or message. ZeroEntropy refers to knowing exactly what the message contains and is associated to a high predictability, low chaos state. In physics, absolute zero entropy is impossible to achieve. But we’ll try!

46. Show HN: ddot – Create short-living .env files from your Password Manager
URL: https://github.com/c100k/ddot
Author: pmdfgy
Description: Hey HN,
I've just released a small utility tool I made in Go, to create short-living .env files from your password manager. At this moment, it's compatible with bitwarden and 1Password.
It's not a super fancy project, but I've been using it for a long time now, and thought others would like to use it as well.
Why did I build this ?
First, for fun and to practice Go.
Second, in terms of security, I've always found it a little bit odd to have .env files lying around in clear on our disks. Especially when they contain sensitive secrets. We've seen a surge of attacks against developers with malicious npm packages exfiltrating .env files to steal credentials and crypto wallets. Although this does not protect completely, it's still better than nothing.
Finally, I once lost a .env file because of a wrong action. Since it was not under source control (for basic good practice), I had to create it all over again. Super painful.
Would love your feedback on it. Please note that it's still a work in progress and I've only tested it on mac arm64.
NOTE : the source code is not available yet as I want to clean it and document it correctly first. Typically, I have a Provider interface currently implemented with File, bitwarden cli and 1Password cli. But I want to add more implementations in order to find the good trade-off between not abstracting and abstracting too much.
NOTE 2 : As stated in the README, password managers already provide solutions for this problem but I simply didn't like how they are "too invasive" in the development workflow.
Cheers.

47. Show HN: Mdfried, a terminal Markdown viewer that renders big headers
URL: https://github.com/benjajaja/mdfried
Author: the_gipsy
Description: mdfried renders markdown headers as big text, two lines high, by generating an image with the same font as the terminal.
It uses [ratatui-image][1] to render the images in the appropiate graphics protocol (sixel, kitty, or iterm2), if the terminal supports it.
Check out the gif in the README.md (e.g. on the github link) to get a better idea on what it actually does and looks like.
There is a setup step the first time you run mdfried, where a font must be picked (ideally the same font as the terminal). The first matching font for the prompt is previewed, you can force to run it again with --setup.
There are still a lot of missing features (and probably bugs), as I just published/released this. If your terminal supports any graphics protocol, and you're curious, please try it out! Feedback is welcome.

I noticed that I often struggle to grasp how long certain phases of my life lasted and how close together certain events occurred. To address this, I created a tool to help me see the bigger picture, and it revealed some surprising insights about my life. Give it a try! It is super simple.

52. Show HN: Safe Link Checker by Ox Check
URL: https://oxcheck.com/safe-link-checker
Author: BrunoBernardino
Description: For the last couple of months I've been working on a Safe Link Checker, which checks a link against a few things:
- Malware/spam domain lists
- WHOIS details (like registrar and domain age)
- Anti-virus (if it's a file)
- Source Code analysis via AI (if it's not a file, to analyse if there's something "shady" in the source code)
In private beta, most people found the anti-virus and the domain age check to be the most useful data points, and many have created Shortcuts (iOS and macOS) to use the "share" pane to check a link in many apps.
There's also a Safe Email Checker and a Safe API which are in private beta. Feel free to request access if that's something that you could be interested in.
Any and all comments and suggestions are welcome!
I do have a final question, which I haven't heard any requests about, but I have wondered if a Chrome and Firefox extension would be helpful, to simply right-click a link, instead of having to open oxcheck.com, for those not using Shortcuts/Apple.
Thank you!

URL: https://defolio.pages.dev
Author: DocFeind
Description: Hey HN,
I'm excited to share de'Folio, a privacy-first investment analysis portfolio manager I built. de'Folio is entirely client-side, ensuring your data stays on your device – no signups, servers, emails, clouds, or AI training involved.
The idea started simple, I wanted a better CSV data viewer that wouldn’t compromise my privacy. What I ended up creating is a tool worth sharing. It's designed for those who value their privacy and want control over their investment data, specifically, initially, me :)
Features:
- Client-facing and no signup needed
- Privacy-first: No data sending
- Comprehensive Analysis: Generates totals breakdown of multiple account types and/or brokers
- Data Organization: Generates tables of holdings with data, P&L, filtering, and sorting
- Visual Insights: Generates holdings, broker breakdown, P&L, cost vs value charts
- Easy Review: Includes search and filters for detailed review and analysis
- Simple drag-and-drop interface
- FAQ/How To guide
I'd love to hear your feedback and thoughts on how deFolio can be improved, or what I overlooked. Try it out and let me know what you think, or roast me on my design, all input is appreciated!
Cheers

Author: hxii
Description: I was somewhat hesitant about sharing this personal projects, especially since I just saw that cool looking Werk[1] tool posted, but I figured that my ADHD-fueled creation might still have it's own place to be.
I just finished rewriting the code for a personal tool I use to automate terminal tasks while minimizing the amount of Python/Bash code I have to write.
As with all other tools I create for my own use, the guiding principle is simplicity and approachability, as if the tool creates more issues or friction than it solves, I'll get discouraged from using it again.
