    Hi - I'm part composer, part engineer and big fan of reading blogs where people learn out loud or with the garage door up by sharing their notebooks or journals. I've been doing this in Moleskines for years (going back to the 80s) but made it a new year's in 2024 resolution to post SOMETHING everyday, so long as I created the sound. I have a big archive of demos and seeds of ideas, so I figured it wouldn't hurt to do something with those in the process. Being so steeped in programming for the last 30 years, a healty chunk of this material is made via coding with Csound, TidalCycles, some raw…

    I am a non-hacker "idea guy" with zero discernible talent. Like most, the story starts with me doing things the hard way. I dreamt of a tool that would save me countless hours. Like most of my ideas, it was supposed to die in a couple of hours, but this one had some legs.... "If I needed this, surely others did too" kept looping in my head. Could I get this built? Could I build it myself? Nah...too lazy to learn how, but before I did anything, I had to promise myself one thing: No more ideas! If ideas were sit-ups, I would have a six pack instead of this tire. It was a constant mental…

    I had a dream on Nov 21, 2019 of a game. I woke up at 4:00pm that day, started programming it then, and 7 and 1/2 hours later, it was done. It's about you and a pink square going exploring. - otdav33/spelunko

    Hello all, I built about 2 years ago a coding website for kids, teens and adults: https://codeguppy.com Despite my efforts to promote the website it is still not well know. I post almost daily about it on Twitter at https://twitter.com/codeguppy ... but even there I don't have views. The website is fun... although I still have a ton of things to add. I appreciate if you take a look and suggest improvements and most importantly help me with spreading the news about this website. I really need a boost! Thanks all!

    Hi everybody, I personally found the best way to motivate yourself to program everyday is by creating a practice repo and by uploading anything you code up that day into this repo. This is a great way to stay consistent seeing the bright green light up every time you push your code. It's very addicting and satisfying, and has definitely made me a better programmer over the past few months.

    Hi everyone, I just saw a vibe coded game on HN, and thought maybe I should post about this here. I'm organizing a vibe coding game dev competition called Vibe Jam. Last year we did it too and there was 1000+ games submitted. This year the deadline is May 1 and you can submit your games until then. There's $35,000 in prizes with the Gold prize being $20,000. Let me know what you think! -Pieter

    Hi HN! Writing has been a big part of my life for the last few years. It's helped me make sense of the world around me through journaling, and my blog and technical books have made wonders for my career as an engineer. Something I've always been missing is an online community where I can practice my skills and learn from other aspiring writers. I built Tavern, hoping to solve my own problem. Its main concept is that every Monday everyone in the app gets asked the same writing prompt and you have seven days to submit your answer. You can look at what others have posted, but only after you've…

    I'm using AI (mostly Claude) to create/publish a new video game every day This is day 33, first stab at the tower defense genre. Most of the games (including this one) I build with a single prompt. Rarely, a couple extra prompts are needed for bug fixes or to tweak the physics/UI. Extremely rarely, the AI has difficulty making the game work right (usually drawing it) and it takes a dozen or more prompts -- but the majority of the time, it gets everything right and makes a fully playable game first try Happy to answer any questions, just a little hobby project of mine I'm having…

    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…

    Read an article yesterday about the H.264 codec increasing their licensing fee by an astronomical amount. And as always, my first shot was how hard could it be to try and build a codec which could be that efficient. I've personally been on a drive to improve my ability to one-shot complex features, products, or make even surgical changes. It's been a few months since I've been doing that, and honestly, results have been great for both work and work/life balance. This was a fun experiment. It burned through tokens, but it helped me identify some more improvements I could make to my…

    Hey everyone! We spent the major part of the year preparing an idea we had for the YC application. At last minute, we decided not to go through with YC. I mean, we've had our fair shares of failed startups and this was one of those make it or break it scenarios. We took everything we've ever learned and strived to make an app that we were proud of. We spent so much effort into making this app that we couldn't bear stopping short and applying to Y Combinator. (Mind you, there's nothing wrong with YC.) We didn't want to apply to Y Combinator at the last minute because if we had really gone…

    Hi Hacker News! My friend and I [1] would like to share with you something we did this week-end. We really like the idea of game jams like the Ludum Dare, and we’d like to participate, but it’s often complicated for us, as we are often limited by the rules inherent to this kind of competition: we have to be available at specific dates, and the rules doesn’t always work for us. For example: if you want to participate as a team in a Ludum Dare compo, you have 72h instead of 48h, and you are not required to publish your code. We realized that what we really like is: - To work together. - The…

    Over the past three months, I’ve been working with my dad on this app as a way to learn Cursor, shadcn/ui, and Next.js. I’m currently studying UX design at the University of Michigan, and I’ve been really impressed by how much vibe-coding tools have advanced over the last six months.

    Hi HN, I’m an indie developer and I built Codenhack because I’m tired of the "setup barrier" for new learners. I believe that if someone wants to learn, they should be coding within 10 seconds—not spending 2 hours debugging local environment variables or Node versions. How it works: I’ve built a browser-based environment that provides a functional terminal and a code editor with live previews. It’s essentially a "lab" where beginners can execute real commands and see immediate UI/logic results. Why I’m showing it to you: I’m currently building this in public and would love some…

    Howdy friends. I've been a zero to one product manager for 12 plus years and along the way I kept borrowing pieces from different discovery frameworks until I had a methodology of my own, one that actually raises the odds of an idea succeeding. This does not replace user interviews obviously, but it leads you in the right direction. Looking forward for your feedback

    I know mentioning Michael Seibel is almost cheating, but this week he demonstrated the "leaky pipes" concept to me. Not that I know the guy, but in one of his videos he says something on the lines of "If you are unsure if you app is ready to be launched, just launch it. It's like a house with leaky pipes, just open the main, grab your tools, and start fixing wherever water is leaking". So we did it, we launched drummy earlier this week on /r/InternetIsBeautiful and we got very close to 10k users in just one day! Survived the hug of death, learned a ton, and made changes all around.…

    Hi Hacker News! My Co Co-op Matt and I are on a work term and were given the task of building a webapp that could make $20 in four weeks as our onboarding challenge. We're in the final stretch here and would sure appreciate HN's thoughts (we realize we kind of did this backwards, building something first before talking to people who might use it, but hey! We're leaning.). So basically, we tried to apply game dynamics to retaining visitors to websites by offering a reward (ie. discount coupon / premium content, etc.) for meeting various 'objectives' (ie. pages to visit). We call it ScavSite…
