Show HN: Simply explain 20k concepts using GPT Hi HN! I made a tool that autogenerates simple, high-level explanations of concepts and organizes them in a somewhat university course-like structure so that it's easier to see how things are structured. Currently it has about 20,000 concepts on a range of topics but that's just what I generated so far, it should work with more obscure topics in the future. I love learning about random topics where I don't have a good background in like history or linguistics, but it's hard to figure out what topics there (you don't know what you don't know) are in certain fields and what they are even about, so this was a way to get the high level idea about random things that I wanted to know about. It also only uses the information in the GPT model at the moment, so obviously information can't be trusted completely and you should definitely double check any information you read here by Googling. I'm thinking of doing the

Show HN: Cadseer. a parametric solid modeling CAD desktop application Cadseer is in the same genre as: solidworks, inventor, freecad etc... Cadseer is alpha software, so lots of missing features, bugs, crashes, file incompatibilities etc... About me: I spent 15 years designing stamping dies on a high end cad system. During that time, I also developed and marketed extensions/plugins toward that cad system. Through that experience, I came disillusioned with 'vendor lock-in' and proprietary software in general. I basically retired, took the vow of poverty and moved all my computing to open source. I have since, and continue to, try and improve the open source cad environment. https://ift.tt/izuyZtN April 1, 2023 at 12:05AM

Show HN: Cicada: A FOSS, Self-Hosted Alternative to GitHub Actions and Gitlab CI Hi HN! My name is Logan Hunt, and I am the founder and CEO of Cicada. Cicada is a self-hostable CICD platform that integrates with GitHub and Gitlab, allowing you to write workflows without caring about the underlying implementation details of the platform you are using. Source code (AGPL-v3 licensed) is available here: https://ift.tt/UgS2wBP and the live site is available here: https://cicada.sh With Cicada you build automation workflows using our custom DSL (domain specific langauge), built specifically for writing automation workflows. The Cicada DSL is a fully functional programming language, meaning you can use variables, if statements (coming soon!), and execute shell commands without having to write a single line of YAML. And, best of all, these workflows can work with GitHub and Gitlab without any modifications. One of the best parts of GitHub Actions (IMO) is the ability to easily trigger workflow

Show HN: Time-tracker that helps me with context switches and documentation Hi HN! I was feeling incredibly frustrated with my struggles in context-switching and writing documentation, so I decided to take action and find a solution. I wrote a simple tool for Alfred and Raycast that helps me be more mindful when switching between tasks, which can even prevent some of those switches. Plus, I can jot down quick notes on each task as I go, making it easier to document everything once I’m finished. This tool is really simple with only 5 commands - tsr, tsn, tsl, tsv, tse tsr writes a new record tsn writes a new note tsl shows you the current task tsv builds a static html page displaying a single timeline of the tasks and notes tse opens the directory where records are stored for easy manual editing TSR stores your data as simple csv files in ~/tsr, making it super easy to integrate with other tools or perform your own custom analysis and visualisation magic. The built-in tsv timeline visua

Show HN: GPT-Shell – An AI-Powered Bash Shell Hello HN folks! I've been working on a side project called GPT-Shell, an AI-powered command-line interface that aims to revolutionize the way we interact with our development environment. I'm thrilled to share this early, slightly buggy, but functional open release with you all! GPT-Shell leverages state-of-the-art language models to interpret natural language inputs, allowing you to write code, perform complex tasks, or even troubleshoot issues using simple, human-like commands. While it's still a work in progress, I believe that it has the potential to make our lives as developers easier and more efficient. Keep in mind that this is a first release, and it might have its quirks. I'd appreciate any feedback, suggestions, and bug reports from you—the passionate and knowledgeable tech community—to help me refine and improve GPT-Shell further. Feel free to dive in, explore, and let me know what you think. I'm eager to hear

Show HN: Create a “rogue” WiFi AP & Captive Portal with a Raspberry Pi This project makes a Raspberry Pi pretend to act as a WiFi hotspot with a captive portal. It does not actually provide an internet connection to connected clients, but simply triggers their captive portal detection, which causes them to present users with a browser window containing content of your choosing. I created this for security tinkering purposes, but also because I found the documentation for similar projects lacking. I've attempted to document and explain the salient points of the entire Raspberry Pi Linux configuration relating to the captive portal. https://ift.tt/7uDFX5x March 24, 2023 at 03:20AM

Show HN: PromptLab–Prompt Chain Iteration for Nontechnical Users Hey HN! We built a user-friendly tool that allows non-technical domain experts to explore and evaluate the effects of LLM-generated prompt chains on large datasets (via CSV).

Show HN: Datapane – A new way to build reports, dashboards, and apps in Python Hello HN! We’re Leo and Mandeep, founders of Datapane ( https://datapane.com ). We're building a way to create reports, dashboards, and web apps from your existing data using Python. Think of it as a combination of React and htmx, specifically designed for the Python data stack.

Show HN: Public transportation signage based on bloom filters (rough mockup) Hello, I was running around Germany, hectically navigating public transportation, and getting lost all the time. I noticed that every station had i platforms, each used lists of n buses (trains, whatever) arriving, each has their list of m destinations. That means I would be scanning i x n x m items just to see if I was at the correct stop. As I was nervous, for every bus that arrived, I would rescan the list of stops to double check. I began thinking how I could make a better system. Linked is a very shoddy mockup of how bloom filters could be used to allow passengers O(1) lookup time for which platform+bus is the correct one. I believe it's likely for public transportation to grow increasingly more complex in the future, as population grows, and under the current list-based system, this will make the signage ever more complex. I think some bloom filter mechanism could reduce that complexity. So, here is

Show HN: Watermelon – GPT-powered code contextualizer Hey there HN! We're Esteban and Esteban and we are looking to get feedback for the new version of our GPT-powered, open-source code contextualizer. We're starting with a VS Code extension that indexes information from git (GitHub, GitLab, or Bitbucket integrations available), Slack and Jira to explain the context around a file or block of code. Finally, we summarize such aggregated context using the power of GPT. As devs we know that it's very annoying to look at a new codebase and start understanding all the nuances, particularly when the person who wrote the code already left the company. With this problem in mind, we decided to build this solution. You'll be able to get into "the ghost" of the person who left the company. Soon, we will also be building a GitHub Action that does the same thing as the VS Code extension but at the time of creating a PR: Index the most relevant information related to this ne

Show HN: Great Books Homeschool beta program I built this customizable literature-based K-12 homeschool curriculum, based on my experience as a homeschool parent. It's designed especially for intellectually curious kids who love to read. One of the main benefits of homeschooling is the ability to design customized programs of study that let kids learn at their level of challenge in each subject. But since designing custom curricula from scratch requires a huge time commitment and familiarity with children's literature and academic materials, most homeschooling parents don't take advantage of this potential and instead opt for prepackaged curricula. Great Books Homeschool eliminates a lot of the work involved in designing a complete and rigorous curriculum for homeschooled students. The website generates a default program of study for each student, then helps parents customize it. Transcripts and other records are generated automatically. Pricing is normally subscription bas
