Show HN: Pyflo – a free, interactive guide to learning Python TL;DR: https://bit.ly/3Ye3QIt is a free, interactive guide to learning Python Hi Everyone, I am a CS educator who has taught a variety of university courses, including many on introductory Python programming. Over the past few years, I've written down a number of Python programming lessons and has culminated into Pyflo.net. This tool is a completely free, introductory guide to learning Python. It is more-or-less an intro programming textbook, but with a few twists, including: * It is totally free. You don't even have to give me your email to use it * The lessons are short and modularized * It's interactive, containing embedded questions that provide instant feedback throughout. My hope is that this can be a useful resource for those looking to learn Python. Feel free to use yourself, or share with those you think would be interested. Feedback is very much welcome and appreciated. https://bit.ly/3Ye3QIt July 30, 2023 at 11:49PM

Show HN: Vite React Boilerplate – A Production Ready, Scalable Starter Template https://bit.ly/3rQUGFV

Show HN: Vite React Boilerplate – A Production Ready, Scalable Starter Template Hello everyone, I’ve created this starter project for creating production ready web apps in Vite and React that I hope some might find useful. This template came about as a necessity to provide some standardization across new projects at work. A few of the initial goals when creating this project were to: - Reduce setup time - Standardize codebase with ESLint and Prettier - Improve commit messages with tools like husky, commitizen and commitlint - Improve codebase maintainability and scalability by providing a reasonable folder structure - Simplify React Component development through use of tools like Storybook - Improving codebase stability with unit and E2E tests via Vitest + React Testing Library and Playwright respectively - Ease the deployment process by providing a simple starter Dockerfile In addition to all the aforementioned goals, I also wanted to use modern tools such as React Query + Zustand for state management, React Hook Form + Zod for creating and validating forms, Tailwind CSS for building out UI’s, etc. I tried to cover everything I, and others, might need but recognize that everyones requirements are different. Luckily, this isn’t a framework so removing unneeded packages or adding new ones is as simple it would normally be. The project itself doesn’t come with a demo as its purpose is to simply provide a foundation for any new projects you might have in mind. Feedback is always welcome and I appreciate anyone willing to checkout this project. Thank you and have a great day. https://bit.ly/3O6A1oI July 30, 2023 at 12:49AM

Show HN: Scribe – android dictaphone with speech recognition on device https://bit.ly/3OxuGIv

Show HN: Scribe – android dictaphone with speech recognition on device Dear HN community! We are developing Scribe - dictaphone with speech recognition on device. On device means - audio is not sent to any cloud and stays on your phone, so it is private. The neural network runs right on the CPU of your smartphone. The app is free, there are no limits or fees based on transcription hours, one can transcribe 24/7 and pay only for electricity. This is actually a demo of our SDK, which we offer to businesses to embed in their applications, and it will stay always free for private users. It is like Google Recorder, but unlike Otter.ai or other transcribing apps based on Google Assistant. https://bit.ly/456XEUZ... Some of the features: - record to wav, flac, aac and transcribe in real-time - transcribe from audio/video files - share to and from Scribe - access records and texts easily from file system Some of the possible uses: - transcribing lectures/trainings - court hearings - medical/psychological interviews - journalist interviews https://bit.ly/3rTnWvO July 29, 2023 at 02:52PM

Show HN: LLMFlows – LangChain alternative for explicit and transparent apps https://bit.ly/47m9tZw

Show HN: LLMFlows – LangChain alternative for explicit and transparent apps Hi HN! Over the last several weekends, I've been building LLMFlows as an alternative to langchain. There's been a lot of discussion on the shortcomings of langchain in the past few weeks, but when I first tried it in March, I thought there are 3 main problems: 1. Too many abstractions 2. Hidden prompts and opinionated logic in chains which makes it hard to customize 3. Hard to debug This inspired me to try and build a framework that solves these 3 issues, and therefore I started building LLFlows with the "philosophy" of being "simple, explicit, and transparent." A few weekends later, I think I finally managed to reach a state where I feel it's ready to be shared. I would love to hear your feedback! Thank you! https://bit.ly/3OdXiVJ July 29, 2023 at 03:03PM

Show HN: I built an iOS app that helps YouChoose faster https://bit.ly/476duRB

Show HN: I built an iOS app that helps YouChoose faster Hey, This is Yash here. I built YouChoose because I was confused about how to have my eggs - scrambled or as an omelet. This made me realize..... In life, we spend too much time thinking about our choices rather than making a choice. These things take up too much mental bandwidth that is better utilized elsewhere. In most circumstances, we just need to make the call - the more we delay, the more it exerts us. Input your two choices. Hit the Choose button. And that's it. There's only one caveat - you can't go back (for the same choices). YouChoose is my micro effort to introduce some randomness in people's life. I am eager to hear your thoughts and comments! https://apple.co/3rDMEzV July 28, 2023 at 01:05PM

Show HN: AI-utils.js – TypeScript-first lib for AI apps, chatbots, and agents I'm building LLM (and diffusion model) apps (and agents) and was not that happy with the existing libaries. Either they take away a lot of control (especially over the prompts) or they are just the raw APIs, e.g. OpenAI. So I wrote a lib that tries to cover the middle ground and provide additional functionality (e.g. type checking and LLM abstraction) while letting you fully control the prompts etc. https://bit.ly/3OalU1I July 27, 2023 at 09:43AM

Show HN: Share your gratitude in public one sticky note at a time https://bit.ly/3QceMEv

Show HN: Share your gratitude in public one sticky note at a time Gratitude deserves to be seen. Each of us can point to individuals who've impacted our lives in significant ways. Perhaps it was a mentor who guided us, a friend who stood by us during challenging times, or a family member whose love was unwavering and unconditional. However, they don't get to hear our appreciations, especially in public. In many organizations, we've embraced the practice of expressing gratitude to our colleagues through karma points, kudos, or similar recognition. While these gestures are valuable, they often happen behind closed doors. Therefore I made this little website so that we can share our gratitude in public and inspire others to do the same. https://bit.ly/3QfHHYp July 27, 2023 at 09:13AM

Show HN: MUI Toolpad – Open-source, local-first, admin app builder https://bit.ly/3KerAq4

Show HN: MUI Toolpad – Open-source, local-first, admin app builder Hi HN, Prakhar, Jan, Pedro and Bharat here - we are excited to introduce you to our product, MUI Toolpad. It’s been more than a year since we started working on it and are glad to show it to the HN community today. Toolpad is an open-source, self-hosted internal tool builder designed for backend and full-stack developers who want to build web apps like analytics dashboards, CRUD interfaces, and utility apps quickly. Toolpad comes as a Node.js package that integrates into your backend and harnesses the speed of its drag-and-drop UI builder for the frontend. It comes with 16 pre-built Material UI components to build UI in seconds. You can also import and use external React components in the drag-and-drop builder. Toolpad runs completely locally which means you're not stuck with an online code editor or a suboptimal GitHub integration. It lets you use your own IDE and extend your existing functions to the canvas through our intuitive queries. All configuration is stored in local files which you can version-control, edit, and deploy in any way you want. You can check out our live demo [1]. If you find it useful, you can support us by giving a star on GitHub [2]. We released our public beta [3] this week. We are happy to answer any questions/feedback in the comments.
