I've been a longtime member @ HN, but I haven't been a developer. In fact, my only HN submission has been one asking how to learn to code (http://news.ycombinator.com/item?id=820741). My cofounder and I decided to solve the problem by making a simple, interactive way to get started with Codecademy. We'd love your feedback. If you're interested in helping us to get more courses up (on any topic!), please send us an email at [email protected].

https://www.manning.com/books/data-oriented-programming-in-j... This book is a distillation of everything I’ve learned about what effective development looks like in Java (so far!). It's about how to organize programs around data "as plain data" and the surprisingly benefits that emerge when we do. Programs that are built around the data they manage tend to be simpler, smaller, and significantly easier understand. Java has changed radically over the last several years. It has picked up all kinds of new language features which support data oriented programming (records,…

The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community. Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned. But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion…

Hi, I've been developing an HTML5 MMORPG game where people can submit code to play a game, like collect items, destroy defense towers or kill monsters, etc.. I've been working on this for over 1.5 yrs (all my spare time) and now it's ready for preview, does anyone want to try it out? It's mostly opensource (and the rest will be opensource sooner or later) Please access it with PC, it's an HTML5 game: https://bytelegend.com/ I really want it to expand to more languages, but right now I've only finished Java part. I wonder if anyone can help me with other languages. Besides, I'm…

I've been working for about 8 months on http://www.Learneroo.com, a site to teach programming and more through challenges. I created the site and all the content on it, and I'm looking for some feedback. Thanks!

Hey! I’m JC. I’m 17 and part of Hack Club, a nonprofit where we help teenagers ship programming projects with their friends while growing technically. A while ago, I asked myself the question, “How exactly do programming languages work behind the scenes?” It seemed really daunting until I went to a half hour workshop at a high school hackathon about writing a tree-walk interpreter and realized that getting started was actually super fun. This guide is designed in the vein of that - to get people, especially teenagers, started on learning how to build a programming language in a literal…

Hi HN! Silk is a project I began working on approximately six months ago without any prior experience or knowledge of compiler design, and it's been a frustrating but fun learning experience. It is very much a work in progress, but I would love to hear feedback of any kind!

I'm a long time lurker that recently quit my job to work on my own projects, a lot due to the inspiration from Hacker News. Now I have published my first serious project, an app for learning how to write Japanese characters. It's the app I always wanted but couldn't find when I was studying. It tries to be simple to use, you just start the quiz and go with the flow. There's no need to plan and manage your studies, and it uses spaced repetition for better retention. There's a promo page with more details up at http://www.kanjibyhand.com. It's only for Android so far. The free version includes…

I've been working on this small, slightly weird expression-oriented programming language for a little while now and feel ready to share it with others. I use it pretty often now in my day-to-day and work life, as a scratchpad for doing a bit of quick math or picking some pieces of data out of a JSON payload. Would really appreciate any feedback about the syntax, docs, features that are glaringly missing, etc. Before anybody mentions it: I know the performance is pretty lousy when dealing with a lot of data. If you can believe it, the runtime is about 100x faster than it used to be! Long term…

After 6 years of coding almost every day, I'm finally ready to show HN. There's a lot going on here, looking forward to your guy's feedback.

Over the past couple of years, I've been very impressed by Kale Davis's Hacker Newsletter and Peter Cooper's entire newsletter empire. They're clearly meeting people's need to stay caught up on industry news without spending their entire lives watching HN and Twitter. Their success has inspired me to try something similar. So I've just begun publishing a JS newsletter called "A Drip of JavaScript." Rather than focus on the latest JS news (which JavaScript Weekly already does rather well), each issue is just a short article about some aspect of programming in JavaScript. The newsletter is…

Hi HN, Over past few months, some of us had been collecting links to learning resources (courses, interactive explorables, books, podcasts, apps, forums, livestreams etc) in a GitHub repository of markdown files. Since we also wanted to have features like advanced search ("Show me podcasts on machine learning which are entertaining and less than 40 minutes long"), we felt the need for an app. Give it a try: https://learnawesome.org You can think of LearnAwesome.org as a GoodReads-equivalent tool generalized to links to ALL media (not just books). Some features you might like: -…

Knit was created to solve pains of other LLM playgrounds. Some of the highlights: - Smart prompt builder, create prompt with simple requirement and few shot learning, fast and effortlessly. - Function call simulation, visualize the function callings and you can also setup a mocked value to return. - Support OpenAI/Anthropic/Azure models. - Manage prompts with projects and members. - And so much more! I have been developing Knit by myself for over 4 months now, and am looking for ways to improve it. Any feedback is appreciated.
