Show HN: Openexus – Building blocks for the internet
26 by lominming | 7 comments on Hacker News.
Hi HN! We are thrilled to share a sneak peek of https://openexus.com after months of work. You can try out the cool demos on the front page! The idea is to build a platform and community for composable building blocks where anyone can easily create, find and connect different modules to create dynamic and interactive apps, sites, dashboards, and docs. This can be done without using a single line of code. Key principles of what we are building: 1) True composability that enables infinite possibilities — Modules today are either too complex to be used only by developers (e.g. NPM packages) or too simplistic where they are usually used as an embed in isolation. We are establishing a modularization foundation that is powerful enough for developers to express functionalities, simple enough for anyone (even kids) to use, and flexible enough to build sophisticated creations. 2) Smart connect without code — All logic can be clearly expressed by simply drawing lines. Depending on the data type and other characteristics of the connector, we can figure out how the connection should behave. For example, triggers can only be connected to actions, and data connectors that fetch from APIs can be defined as directional read-only connectors. 3) Open-connections for instant forking — Forking today is a time-consuming complex endeavor. Even a simple change requires many layers of code understanding. Instead of open-source code, we see a future of open-source connections, where remixing simply means adding new blocks and re-wiring them. What we are building can be described as NPM for non-developers, connectable Lego blocks for the Internet, or Minecraft for non-game creations. Our focus is to create a community where we can share ideas and innovations. We are super excited about the possibilities of this platform, especially when we incorporate AI. We will be releasing tutorials, opening up the playground, and sending out invites in the coming weeks. If you are eager to try out our tooling and create your own building blocks, drop us an email! We would love to hear your feedback! Website: https://openexus.com Email: m@openexus.com

Show HN: Khoj – Chat Offline with Your Second Brain Using Llama 2
53 by 110 | 4 comments on Hacker News.
Hi folks, we're Debanjum and Saba. We created Khoj as a hobby project 2+ years ago because: 1. Search on the desktop sucked; we just had keyword search on the desktop vs google for the internet 2. Natural language search models had become good and easy to run on consumer hardware by this point Once we made Khoj search incremental, I completely stopped using the default incremental search (C-s) in Emacs. Since then Khoj has grown to support more content types, deeper integrations and chat (using ChatGPT). With Llama 2 released last week, Chat models are finally good and easy enough to use on consumer hardware for the chat with docs scenario. # Overview Khoj is a desktop application to search and chat with your personal notes, documents and images It is accessible from within Emacs, Obsidian or your Web browser It works with org-mode, markdown, pdf, jpeg files and notion, github repositories It is open-source and can work without internet access (e.g on a plane) # Chat Extract answers and create content from your existing knowledge base Online or Offline: Chat without internet using Llama 2 or with internet using GPT3.5+ depending on your requirements Example: "What was that book Trillian mentioned at Zaphod's birthday last week" We personally use the chat feature regularly to find links, names and addresses (especially on mobile) and collate content across multiple, messy notes # Search Quickly find relevant notes, documents or images using natural language Does not use internet Example: Search for "bought flowers at grocery store" will find notes about "roses at wholefoods" # Quickstart pip install khoj-assistant && khoj See https://ift.tt/DoamiLw for detailed instructions We also have desktop apps (in beta) at https://ift.tt/jtNgnpA if you want to try them out --- Please do try out Khoj and let us know if it works for your use-cases? Looking forward to the feedback!

Show HN: Free AI-based music demixing in the browser

Hi all, I've spent some time working on music demixing or music source separation algorithms, which take in a mixed song and output estimates of isolated components (e.g. vocals, drums, bass, other). I took a popular PyTorch model with good performance (Open-Unmix, UMX-L weights), reimplemented the inference steps in C++, and compiled it to WebAssembly for a free client-side music demixer.

Ask HN: What boosted your confidence as a new programmer?

When anyone starts out in a new craft, even after grasping the fundamentals of the tools they are quite shaky and low on confidence until they have a significant experience in doing something that ultimately ramps up their confidence in their craftsmanship. Similar things happen with novice programmers when they start out. Then they read a beautiful codebase which they can fully understand and replicate, or build a project from scratch, or read a book or take a class on a subject. And their confidence is tremendously boosted thereafter. What was it for you? How did you gain this confidence to take the first step from being a tinkerer to being a skilled craftman?
