Products that do what SirixDB – versioning through efficient snapshotting does
I've already posted yesterday, but I'd really love to get comments, any kind of questions, suggestions and help would be greatly appreciated as it's an Open Source project of mine (and was for others during my studies at the University of Konstanz 6 years ago). Since then I spent countless ours to bring forth the idea of a versioned storage system, especially well suited for analytical tasks for timd-varying data. Especially I'd love to discuss what documentation you need, which next steps are necessary (JSON, Cloud...), API additions or changes... I've updated the README quiet a bit, such…

I'm developing a storage system for versioning data at the subfile level, especially well suited for SSDs due to its log-structured COW nature. It implements a novel versioning algorithm called sliding snapshot, a diff-algorithm which makes use of our stable record-identifiers and optionally hashes, another diff algorithm for importing similar XML-documents as a versioned resource as well as novel XPath axis to navigate not only in space, but also in time. Recently, I've implemented a higher level, asynchronous REST-API with Kotlin (Coroutines) and Vert.x in a seperate module. The system is…

Everything that would be here is in the README. I hope this gets big, it has tons of potential.

Hi HN! I just released a blog on the fastest, easiest, and most collaborative AI data version control tools out there. If you’ve been iterating on AI datasets lately, you know how annoying and difficult it is to version and share your data. If you want a detailed comparison on the best data exploration and versioning options from Oxen.AI (where I am currently building a solution), Hugging Face, DVC, etc. check out the blog and lmk what you think:) Here’s the link: https://www.oxen.ai/blog/the-best-ai-data-version-control-to...

I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.

So a while ago I was thinking it would be neat to build a site that had the most absolute utility. The idea I came up with was a site to store those little protips that are super useful, if you know them ahead of time. I hired a guy to work on it with me, and ClueDB was born: http://cluedb.com/ Please give it a whirl (it uses Twitter auth as login but doesn't tweet anything) and tell me what you think! (Various trivia: My first try at a project coded by someone else and "product managed" by me. Runs on Flask + MongoDB. Also, this is totally unrelated to my startup.)

hello! After receiving some great traction here a few weeks back (65.03k unique visitors/ 539.22k total requests/ +11x user sign ups), Stephen and I rolled up our sleeves and made some improvements based on the feedback y'all had. → Migrated the entire infrastructure from Heroku to DigitalOcean w/ Docker → Added functionality for data exports to markdown (take your data anywhere) → Added in a sustainability model with Lemon Squeezy subscription payments → Migrated to a Vite-based build system → Migrated from vuex to pinia for Vue.js state management → Made improvements to the…

Hi HN, I built t4, a datastore that stores its WAL and snapshots in S3. Instead of traditional storage, it writes append-only segments to object storage and reconstructs state from checkpoints + WAL. A side effect of this model is that the database becomes naturally versioned: you can restore any past state, branch from any point (with copy-on-write) and replay history I started this as an experiment to replace etcd in Kubernetes, but it’s evolving into a general-purpose versioned state store. Curious what people think about it and appreciate any feedback!

I had 14,000 photos sitting on a drive and wanted an excuse to play with local vision models and Elixir/Phoenix. I originally tried to get LLaVA to tell me if a photo was 'good' or matched my style, but quickly learned that LLMs have terrible taste. I ended up demoting the LLM to just extract metadata, and built a custom CLIP/Ridge Regression pipeline to actually learn my preferences based on how I rate things. The stack is Phoenix/Oban on the orchestrator side, and Python/FastAPI/Instructor for the AI workers. Happy to answer any questions about the architecture,…

Hello HN, I am Sonal, a data consultant from India. For the past few months(and years!), I have been working on an entity resolution tool to build a single source of truth for customers, suppliers, products and parts. Here is a short demo of Zingg in action https://www.youtube.com/watch?v=zOabyZxN9b0 As a data consultant, I often struggled to build unified views of core entities on the datalake and the warehouse. Data spread across different systems has variations and consistencies making Customer 360, KYC, AML, segmentation, personalization and other analytics difficult. As I…

Hey everyone, I am sharing my open-source storage engine project TidesDB. I'd love to hear your feedback and thoughts. Cheers.

Disclaimer it is a heavily AI assisted project. The goal was not to be the most performative but the kind that's easier to learn from. I wanted to share this in case there are people who had the same idea or wanted to see something like this.

Hey HN! Over the past few weeks, I’ve been working on DataBridge, an open-source solution for data ingestion and querying across text, PDFs, images, and videos. In our latest update, we’ve added a fully local deployment option: - No internet required – Runs entirely offline. - Customizable Models – Supports any LLM and embedding model via Ollama (with options for any other private providers) - Extensibility – You can plug in your own models or tools easily. This local-first approach ensures better privacy, security, and flexibility, especially for teams dealing with sensitive data. You can…

Hi there! I've been working with data in one form or another, professionally, for about 5 years. I've been thinking about my own personal data and how it's used for at least twice that long. I've been sort of building something in my head for a while that solves my own problem and, in the beginning of this year, I found the opportunity to spend some time building it out. I'll leave the detailed explanation to the blog post but, in short, I built what amounts to an API crawler combined with a data processor to help you download your personal data from 3rd party services and work with it using…

597 days ago, I posted about the project our team was developing - https://news.ycombinator.com/item?id=3183322 - here on HN, and today we're finally taking the wraps off what we've been working on since then. At it's core, what we've been building is an end-to-end solution for creating, storing, and working with structured content in a way that's accessible to anyone. You can check out an introduction - http://team.marquee.by/introducing-marquee/ and dig into the technical/philosophical details of our approach -…

Hey Hacker News! Last week we made the codebase for product 100% open source. This week we shipped a dashboard to manage connectors, as well as integrations with Google Drive, Zendesk, Notion, and Confluence. This means Sidekick is now the fastest way to sync data from these tools to a vector database. Why is this important? For developers building LLM apps, data integrations are often the least interesting and most time consuming part of the process. For those that don’t want to roll their own ETL, Sidekick is an opinionated tool that lets them get an API endpoint to run semantic searches…
