Products that do what Weft – A reactive and interactive Python experience does
Hi HN, I built Weft over the last two weeks of Christmas break. I was teaching my kids Python and noticed the lack of interactivity in some of their learning experiences. The feedback loop was too long. I wanted to provide them with an experience similar to Bret Victor's concepts on Learnable Programming; i.e. an easier way to learn is to see immediately the reaction to your actions. Hence the reactivity ;) It is currently in early alpha and I’m planning to open-source the repo under AGPLv3 soon once I clean up the prototype code. I wrote up a short blog post with more details on the "Why"…

Hi everyone! I just released the Practical Python Projects book! (https://practicalpython.yasoob.me) I am happy to announce the first version as a release candidate. I have poured a lot of love into writing this book and would love to hear what you guys think. (A limited 100% off and discount coupons at the end) This is not a pure beginner book. The book does assume some background Python knowledge. You need to know the basics like methods, functions, classes, and such. If I use something that is not typically covered in beginner Python books, I will explain it before I use it.…

This is a little project I've been working on for a while in order to better learn Python. Although IRC may not exactly be the most exciting medium, I still find it to be fun and useful, this interest lead me to writing a bot. In doing this I realized that what would actually be more interesting would be if I had a framework. There may already be such a thing, certainly there are IRC libraries, but I don't know if they're well-suited to deploying bots. At any rate if for no other reason than the fact that I am relatively new to programming and eager to learn I decided to build a framework.…

We did a "Show HN post" 6 months back of our startup and we're very excited to show everyone how far we've come as well as the lessons we've learnt so far! It's been a roller-coaster so far and we think there's lot more of the same to come! We did apply for Ycombinator funding but got turned down :( But may re-apply soon :) For those that don't know, our startup is called Scirra and we make Construct 2 which is an HTML5 game engine (http://www.scirra.com). Our engine allows anyone to make HTML5 games without knowing any programming. It's only me and my brother working on this and we're based…

Hi there, I built a React code editor component that also compiles, executes and returns the outputs of the program written in it (via pyodide/webassembly). I believe that this is a useful package for those building projects with web-based code editors. Expanding the library to be more flexible + have greater language support is a goal for the future. Hope it helps someone out there - please feel free to reach out if I can assist. Feedback and suggestions are always welcome.

Hey everyone, I've been experimenting with collaborative learning and active learning for a while (I launched Coderoulette a couple of months ago) and I'm launching something new today that I'm really excited about. Online learning is pretty passive (video lectures) and lonely, and I think we could create an online learning experience much engaging and effective than that. Only 5% of people who start a Coursera course finish it. My hypothesis is that we can increase that number significantly by matching learners online in teams of 2-3 and giving them a real project to build together. On top…

Howdy friends! Tell me if this is an atrociously terrible idea - I've been working on building a leetcode for clientside devs so we can practice React and Javascript interview questions in a more concise way, I call it clientside.dev I just finished a beta version of it yesterday and plan on releasing it with many more problems on Jan 1st but it's there if you wanna play with it open to any ideas / feedback however mean or nice it may be :)

Recently, I saw few Python accelerators getting a lot of attention, and I thought it would be a good time to finally present the project that we will make available to test in the upcoming days. Flyable is an ahead-of-time compiler that takes your Python code, analyses it, and outputs very optimized machine code. Micro-benchmarks show that it produces programs that run between 10-70x time faster than Python. Flyable is certainly one of the fastest and easiest ways to accelerate your Python code. It finally allows Python to compete in the ring of fast and efficient languages without having to…

Hi I'm the developer of UX-App if you have any questions then fire away :) Just thought I'd give you all some background. I'm a high school teacher by day and developer by night. I was bitten by the start-up bug a few years ago and UX-App is my first product launch. In between a full time job and a 5 month old at home it has taken about 3.5 years to complete the project. I'd like to think its a unique product that holds its own against the existing competition and even has some features that no other tool has. My favorite aspect is the visual code builder which allows designers to easily…

Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

Hi HF, I'm Terrell, and we built an open-source app that lets developers create their own Operator with a Next.js/React front-end and a flask back-end. The purpose is to simplify spinning up virtual desktops (Xfce, VNC) and automate desktop-based interactions using computer use models like OpenAI’s There are already various cool tools out there that allow you to build your own operator-like experience but they usually only automate web browser actions, or aren’t open sourced/cost a lot to get started. Spongecake allows you to automate desktop-based interactions, and is fully open…

Hi HN! Solo developer here. 10 days ago, I started building this after spending countless hours copying/pasting marketing sections and fighting to keep them consistent with our design system. I wondered: "What if AI could understand our design system and generate React components that actually match it?" Current progress (10 days in): - Can generate hero sections that follow your design tokens - Uses your actual component variants and styles - Works with Next.js, Tailwind, shadcn/ui It's very early days, but I'm excited to share it with other devs who: - Are tired of rebuilding…

Hey everyone! Some time ago I was analyzing why React apps are so hard to optimize, and came to a conclusion that the lack of atomic updates is the culprit. I made an experimental library which basically updates everything in place directly in HTML. At some point I became aware that Solidjs exists, which is a very similar idea, but at the end of the day I realized my approach to API is quite different and warrants the existence of my library (my state primitive allows selector subscriptions, array iterators return a state primitive with the element, allowing to never re-render the whole…

I kept on reading you guys on how to do it, how not to do it. On January I started with thinkpython, learn python the hard way, mit course on programming, and every other python material I found. You just need to find the best resourse for YOU. I did Udacity's CS253 course, got my certificate and made my MVP! If your one of those guys like me, just get your ideas out there and the project will push you forward. Farm management software in South America is broken. We still have cd and downloadable updates. We've seen www.farmlogs.com and www.farmeron.com for USA and Europe. How about…

I've built a small compiler, heavily inspired by Svelte, that leans on modern web standards and proposals, namely Web Components, HTML Modules, and Signals. Although web components never really took off, I still believe they have strong potential as a foundation for building web applications without relying on a framework. GitHub: https://github.com/GuillaumeDucret/drop Blog post: https://guillaumeducret.medium.com/web-components-and-my-que... I’d appreciate some feedback before committing more time to this project !

Hi everyone! I'm one of the developers behind this project. I wrote it with my two brothers, Daniel and Ricardo. For years the three of us have been curious about how multiplayer games work, which is why we decided to work on this project. Our goal was to gain a deep understanding of how different players can share the same 3D space, which is why we wrote our own tiny game engine instead of using something like Unity. We wrote the engine using C++ and OpenGL, and we then compiled it to WebAssembly using Emscripten so that it would run effortlessly on web browsers. We are really excited about…

If you really want people to use your stuff, you should make it easy to get started as possible. For interacting with Github Actions, that means setting up OIDC, so you can prove who did what in which repo when - according to Github themselves. That means for a dev on the other end of things, it should be as easy as: ```yaml -uses atopile/do-thing@v1 ``` Hitch is, boy oh boy was this a PITA to get working in the first place. Honestly, I'd probably rather walk on lego for half an hour. Hopefully, this package should make it a piece of cake - and we all have to mint fewer tokens manually

My first public repo intended to be used by others. While I am curious on how you'd use it, I'd love feedback on the code/setup/pythonic nature of it all. I am on a career break and just experimenting a lot, especially on ways to make AI useful for everyday things. I've coded more in the past 6 weeks than the past 6 years and don't know a lot of python devs. Python was never big language at my previous companies, but something I used a lot for tools and projects going back to college compiler days. Old habits die hard. Are there tools that do this as you screenshot? Probably...…

I come from a machine learning background - PyTorch code, leaving a training job running overnight, and Jupyter Notebooks. I hadn't touched much frontend before diving deep into start-ups. It was similar for my co-founder Nick, who spent time working on semiconductors. I started building, and noticing patterns in AI outputs. Enough to be able to understand how a hook works, how to manage state and why Typescript is great. But whenever it came to optimising a piece of code, debugging state issues or designing a codebase from scratch, my mind went blank. I went to ChatGPT Study Mode to seek…

Hey all, I'm a product designer and I built this cause' when I was designing liquidity pool and staking features for this DAO, I didn't know how the user flow worked and how the UI looked for similar pages, so I was constantly switching back and forth Balancer, Uniswap, and OlympusDAO as references. I thought that I might not be the only one with this problem, so I built this library of userflow screenshots, and annotated them, to share with the web3 community of builders, designers, and developers. Would love feedback if you're a builder in web3, let's connect too! (Also I'm aware that…

Hi It's Logan (op) and David, we are launching our first open source Python SDK generator with other languages to come :) We built this because we believe that the OpenAPI Generator project is a mess and simply doesn't work for most users (us included). Additionally, proprietary generators miss the mark for complex use cases, and restrict developers from doing what they do best: writing code. On top of all that they force you into proprietary configuration layers for many desirable features which increases vendor lock in and pulls you further away from your API spec as the source of truth.…

Hi HN! During the last year, I've been building python.cards: a site to learn Python using spaced repetition. My goal is to make the most of spaced repetition by making it extremely simple to use and by providing high quality flash cards. The site has been live for a month, with a few daily users who had joined the waitlist. The feedback has been quite positive, with most of the users using the site every day. Currently, we have a free deck (A Tour of the Stdlib) and a paid one (Pathlib in depth, for $9.99). I have other decks in the works, covering topics such as f-strings, collections,…
