Show HN: Decentralized Database https://ift.tt/qC3DKtn

Show HN: Decentralized Database DB3 is a community-driven layer2 decentralized database network. Infinite Storage Space Scalability is the key to the web3 explosion, db3 will use the following strategies to achieve web3 scale PC can meet the minimum system requirements so everyone can join the db3 network to provide storage space. Using dynamic sharding to achieve scale out. when a storage shard chain has not enough space to store mutation, it will split itself into two subchains. Using cold data archive to recycle storage space. history cold blocks and cold state data will be archived to FileCoin and the storage node will always has storage space to store new data. Blazed Fast and Provable On-chain Query Currently, decentralization means bad performance but db3 is trying to make a big improvement in performance Merkdb is the storage engine of db3 network and it not only has high performance but also the fast-proof generation Geo distribution, the nodes in every storage shard are geo-distributed and the clients can execute querys against the nearest storage node Query session, the first decentralized query protocol to resolve performance and incentive perfectly Crypto Native Data Ownership In the decentralized network, only the private key owners can update their data and they can keep privacy by encrypting their data with the public key On-chain Programmable Dapp developers can develop data processing contracts and deploy them to the db3 network just like developing data backend in web2 Ethereum Guarded Security DB3 network is a layer2 network on Ethereum and all the assets are guarded by Ethereum https://ift.tt/a9bi2CD December 22, 2022 at 07:04PM

Show HN: Write 500 Words a Day https://ift.tt/f0Z8YJT

Show HN: Write 500 Words a Day Hello! I made a web application for my friend and I to use as part of a New Year’s resolution and decided to open it up to the public. It’s pretty simple but I’ve really enjoyed building it and using it so far. I’ve written ~10,000 words, which is a lot more than I used to write. Enjoy and be nice! https://ift.tt/i53HnrL December 22, 2022 at 01:59AM

Show HN: System Design Practice and Discussion https://ift.tt/r5gUx2d

Show HN: System Design Practice and Discussion Many platforms exist for a candidate to practice leetcode style questions. Created one to practice and discuss system design problem statements. There is no auto evaluation as high level design is subjective, but we support upvotes/downvotes and a comment section for feedback and discussion. Looking for early feedback. https://ift.tt/T7DN8sY December 21, 2022 at 10:54PM

Show HN: How to use ChatGPT+ARKit to script experiences with natural language https://ift.tt/wEy2KR3

Show HN: How to use ChatGPT+ARKit to script experiences with natural language Video demonstration: https://youtu.be/bJFa5HOmhl4 I created a demo involving ChatGPT, OpenAI's Whisper running on-device for speech-to-text (because why not?), and ARKit. By defining a custom JavaScript environment with JavaScriptCore and describing it to ChatGPT, I was able to get it to produce functioning scripts that instantiate and manipulate 3D objects. Sketchfab is used to import 3D assets on the fly. Google Poly had a much better catalog of assets for this sort of thing but sadly, it's no longer available. The README.md describes how it all works but the gist of it is that user prompts are wrapped in a larger prompt that describes the environment (i.e., which functions are available to use and how they work) and constraints. The code is then executed directly. Assets for objects are fetched as needed by searching Sketchfab. https://ift.tt/YeCjrEn December 21, 2022 at 11:51PM
