Shared – Triptych for data exchange and persistence
Hi HN! I'm Alex, a tech enthusiast who likes to build stuff from scratch. Often my programs have data to store or a configuration file to read and/or edit. Therefore, I design relational databases [1] and write SQL queries to manage complex data with relationships, and for other needs, I used to do unmaintainable hacks (custom file formats) with plain old files. But that was before I discovered Pickle [2], the Python data serialization module. A simple way to store a representation of memory-living data collections on local disk. Therefore, Pickle became my favorite way to store data,…
Shared – Triptych for data exchange and persistence launched on September 8, 2022 with 14 votes, #985 of 3,464 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 4 years on.
In plain words
Shared is a data exchange and persistence tool designed as a language-agnostic alternative to Python's Pickle module. It allows developers to store and retrieve data collections from disk while enabling data sharing between programs written in different programming languages. The tool addresses the limitation of Pickle by supporting formats that work across language boundaries, making it useful for applications that need interoperable data storage and configuration management without relying on custom file formats or complex database queries.

I built an open-source data copy tool called ingestr2024 · github.com · ▲156Hi there, Burak here. I built an open-source data copy tool called ingestr (https://github.com/bruin-data/ingestr) I did build quite a few data warehouses both for the companies I worked at, as well as for consultancy projects. One of the more common pain points I observed was that everyone had to rebuild the same data ingestion bit over and over again, and each in different ways: - some wrote code for the ingestion from scratch to various degrees - some used off-the-shelf data ingestion tools like Fivetran / Airbyte I have always disliked both of these approaches,…

I’ve been in the MLOps space for ~10 years, and data is still the hardest unsolved open problem. Code is versioned using Git, data is stored somewhere else, and context often lives in a 3rd location like Slack or GDocs. This is why we built XetHub, a platform that enables teams to treat data like code, using Git. Unlike Git LFS, we don’t just store the files. We use content-defined chunking and Merkle Trees to dedupe against everything in history. This allows small changes in large files to be stored compactly. Read more here:…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
