Show HN: Aspen – Distributed Data Platform

This post is to announce Aspen, a new player in the distributed data space. It's designed to fill a niche which is currently not well-served by existing tools which is to be a general-purpose distributed data platform for building higher-level applications like object stores, distributed file systems, distributed indices, databases, etc.What sets Aspen apart is that it uses a new approach to achieving scale that focuses on maximizing flexibility both in options available during application

Show HN: I implemented a RNN from scratch by reading a dense neural network book

Hi everyone. I have been learning about deep learning for some time, and I've tried to implement CNN, neural networks, U-Net, transformers etc. to learn and understand them more and also to get my hands dirty on the frameworks, however I've noticed that many tutorials online are not very detailed, so concepts are not explained clearly, so people would understand neural networks only shallowly. On the other hand, many sources like books may show many, many equations but do not show the

Show HN: A transactional event-driven application platform on Cassandra

Cyoda is a platform for building enterprise-grade, data-intensive backend systems.We’re a small software vendor company with fintech startup clients in production for several years, and we have launched Cyoda as a PaaS to make this technology accessible to a broader audience.You can think of Cyoda as having event sourcing + workflow engine + horizontally scalable database in one integrated system. Processing is transactional, querying is distributed and resilient, and business logic stays modula

Show HN: TypeKro – TypeScript infra-as-code for Kubernetes built on KRO

Hi all,I've been building yet another tool to let people build on Kubernetes and escape the pain of YAML. I've open sourced it under the Apache-2.0 license and would love some feedback.The tool was inspired by KRO (https://kro.run) (a project recently released by Amazon) and builds on top of it. TypeKro is aimed at providing a declarative type-safe user experience to orchestrating complex kubernetes dependencies with TypeScript, so you get your intelli-sense and all the other
