Show HN: VSCode Extension to jump between local git repositories https://bit.ly/3GdfFWr

Show HN: VSCode Extension to jump between local git repositories Hi HN, I've a lot of repositories on my local machine and previously I was using Project Manager extension, but I had some issues with it - - It was kind of slow. - It showed ignored repositories. - It was not completely open source. - There was no automated grouping for repositories. So, I ended up creating my own that does everything above. It's still in early stage but I use it on daily basis. While it's does not have all features of project manager, It takes around 50 ms to detect all repositories inside my home directory. It is powered by a bundled rust binary that does the all the heavy lifting. For those looking for source code - extension - https://bit.ly/39J5cpm bundled binary - https://bit.ly/3wI3uhr I hope it helps someone else as well. https://bit.ly/3wFOMWX May 21, 2022 at 01:23AM

Show HN: Unidata – Providing Easy Access to Human-Friendly Web3 Data https://bit.ly/3Gd98en

Show HN: Unidata – Providing Easy Access to Human-Friendly Web3 Data We all know that it is not that easy for web3 developers(especially for front-end) to access and present Web3 data due to the infrastructure design of blockchains. To resolve this issue, I came up with this human-friendly open-source project Unidata a few days ago. I believe this tool will make Web3 data much easier to access and display for developers. Docs: https://bit.ly/3lv4q25 GitHub: https://bit.ly/3yVAxjz Let's take the most commonly used web3 data ETH NFT as an example to elaborate on the issue. The EIP-721 standard ETH NFT used has a very "flexible" format. An NFT image may use various fields, such as image image_url or animation_url. Depending on the publisher's preference, it might not even be an image at all; it could be a video, a 3D model, etc. The inconsistent formats cause a lot of problems for its front-end presentation. Getting all the Ethereum NFTs owned by a given address is also problematic. Ethereum's design requires you to read all the transaction records of that address to get all its Ethereum NFTs. This is an impossible task for the front-end, but can be partially solved by the various data indexing services currently available. However, the data returned by these services are in different formats, each having its own advantages and disadvantages, while each supports different chains. So how should we choose which one to use? To address the first issue, Unidata has designed a series of user-friendly and uniform data specifications, divided into four sections - Profiles, Links, Assets, and Notes, and Ethereum NFTs fall under the Assets specification. With a fixed data format returned by Unidata, the front-end no longer has to do the troublesome work of adapting a confusing data format. Unidata currently supports Ethereum NFT and Solana NFT as well, and the data specifications for Ethereum NFT and Solana NFT are unified. In addition, Unidata will continue to support more Assets sources, all of which will also have unified specifications. Once the first issue was solved, the second is easy: Unidata's approach is to unify and aggregate the data returned by the various services into the same format. For example, the OpenSea service supports the mainnet, the Alchemy service supports Polygon, the Moralis service supports BSC, Arbitrum, and fantom, and the POAP service supports POAP NFT for the Gnosis chain. With a single line of code from Unidata, you can use these services to get all the NFTs for mainnet, Polygon, BSC, Arbitrum, fantom, and POAP at the same time. An online demo can be seen here( https://bit.ly/3lxJLuq ). Unidata currently supports not only Assets, but also Profiles, Links, and Notes sections. All the services and data sources currently supported can be seen in documentation. - Assets currently support Ethereum NFT(mainnet, Polygon, BSC, Arbitrum, Fantom, Gnosis, POAP), Solana NFT, Flow NFT, and even Gitcoin Contribution. - Notes currently support Mirror Entry, Ethereum NFT Activity(mainnet, Polygon, BSC, Arbitrum, Fantom, Gnosis, POAP), Gitcoin Contribution. - Profiles currently support ENS, Crossbell Profile. - Links currently support Crossbell Link. Many more features are in progress and will be active very soon. Please feel free to give me any feedback. I would like to welcome everyone to join this open-source project. https://bit.ly/3lv4q25 May 20, 2022 at 05:51PM

Show HN: Objectiv – open-source product analytics infrastructure https://bit.ly/3MBQlvQ

Show HN: Objectiv – open-source product analytics infrastructure Hi! One of the creators here. Very proud to finally be able to show you what we've been working on for over a year now. Curious to hear your thoughts! Objectiv is open-source (APLv2) product analytics infrastructure. It's built around a generic but strict event taxonomy, open/common data- and infra tools (currently PG, snowplow, working on bigquery with more to come), and the analyses are done using our pandas-like, SQL speaking modeling library called Bach. As a result, we’re moving towards a vision wherein models can be shared openly, independent of product, platform[1] or data platform[2]. How? - Fully assist the dev doing the instrumentation using tools for ide support, run-time validation, ci integration. No auto capture, but very low-effort[1] instrumentation. - Scale using proven tech: a single collector writing to PG for small or snowplow to anything[2] for big. - Feed data into your own data warehouse after validation. - No tracking plan, but an open event taxonomy designed for modeling, that fits most user interfaces out of the box or can be extended otherwise. - Take some of our pre-built models off the shelf or use Bach directly to model on the raw data in a notebook. - Bach generates SQL for the target platform: productionize without lock-in, feed to a BI system, dbt, etc. Where? Github: https://bit.ly/3lsDJuR Docker demo: https://bit.ly/3Lwoc81 Website/docs: https://bit.ly/3sNkS1B Let me know what you think and what platform/SQL backend you’d like to see supported first. [1] Currently on plain js, react, angular, react native. Future: vue, native android/ios. [2] Once we’re done building Bach support for all SQL platforms. Now: PG, bigquery in development. Future: redshift, clickhouse, athena, etc. https://bit.ly/3sNkS1B May 19, 2022 at 11:45AM
