Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn&#x27;t cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven&#x27;t written real code in years.Fast forward to now. I&#x27;m a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It&#x27;s basically meditation for long-term investors.The problem? Every compound interest calculator online is terrible. Ugly interfaces, ads covering half the screen, can&#x27;t customize compounding frequency properly, no year-by-year breakdowns. I&#x27;ve tried so many. They all suck.When vibe coding started blowing up, something clicked. Maybe I could actually build the calculators I wanted? I don&#x27;t have to be a &quot;real developer&quot; anymore — I just need to describe what I want clearly.So I tried it.Two weeks and ~$100（Opus 4.5 thinking model） in API costs later: I somehow have 60+ calculators. Started with compound interest, naturally. Then thought &quot;well, while I&#x27;m here...&quot; and added mortgage, loan amortization, savings goals, retirement projections. Then it spiraled — BMI calculator, timezone converter, regex tester. Oops.The AI (I&#x27;m using Claude via Windsurf) handled the grunt work beautifully. I&#x27;d describe exactly what I wanted — &quot;compound interest calculator with monthly&#x2F;quarterly&#x2F;yearly options, year-by-year breakdown table, recurring contribution support&quot; — and it delivered. With validation, nice components, even tests.What I realized: my years away from coding weren&#x27;t wasted. I still understood architecture, I still knew what good UX looked like, I still had domain expertise (financial math). I just couldn&#x27;t type it all out efficiently. AI filled that gap perfectly.Vibe coding didn&#x27;t make me a 10x engineer. But it gave me permission to build again. Ideas I&#x27;ve had for years suddenly feel achievable. That&#x27;s honestly the bigger win for me.Stack: Next.js, React, TailwindCSS, shadcn&#x2F;ui, four languages (EN&#x2F;DE&#x2F;FR&#x2F;JA). The AI picked most of this when I said &quot;modern and clean.&quot;Site&#x27;s live at <a href="https:&#x2F;&#x2F;calquio.com" rel="nofollow">https:&#x2F;&#x2F;calquio.com</a> . The compound interest calculator is still my favorite page — finally exactly what I wanted.Curious if others have similar stories. Anyone else come back to building after stepping away?

Hey HN – I built Dock after years of team chat frustrations as a founder.
Free forever for teams up to 5. Unlimited search, unlimited history. No &quot;upgrade to see messages older than 90 days&quot; nonsense.
Built for teams who work both async and sync&#x2F;real-time when it matters. runs on SOC 2 infra, compliant, secure and in-transit and at-rest encryption, runs on Cloudflare.Early stage – would love feedback from anyone who&#x27;s felt the same pain.

Fil-Qt: A Qt Base build with Fil-C experience

Hello all!I&#x27;ve been an avid fan of Pocket Operators by Teenage Engineering since I found out about them. I even own an EP-133 K.O. II today, which I love.A couple of months ago, Reddit user andiam03 shared a Google Sheet with some drum patterns [1]. I thought it was a very cool way to share and understand beats.During the weekend I coded a basic version of this app I am sharing today. I iterated over it in my free time, and yesterday I felt like I had a pretty good version to share with y&#x27;all.It&#x27;s not meant to be a sequencer but rather a way to experiment with beats and basic sounds, save them, and use them in your songs. It also has a sharing feature with a link.It was built using Tone.js [2], Stimulus [3] and deployed in Render [4] as a static website. I used an LLM to read the Tone.js documentation and generate sounds, since I have no knowledge about sound production, and modified from there.Anyway, hope you like it! I had a blast building it.[0]: <a href="https:&#x2F;&#x2F;teenage.engineering" rel="nofollow">https:&#x2F;&#x2F;teenage.engineering</a>[1]: <a href="https:&#x2F;&#x2F;docs.google.com&#x2F;spreadsheets&#x2F;d&#x2F;1GMRWxEqcZGdBzJg52soeVaY7iUSj1YncfIJZIPScBhM&#x2F;edit" rel="nofollow">https:&#x2F;&#x2F;docs.google.com&#x2F;spreadsheets&#x2F;d&#x2F;1GMRWxEqcZGdBzJg52soe...</a>[2]: <a href="https:&#x2F;&#x2F;tonejs.github.io" rel="nofollow">https:&#x2F;&#x2F;tonejs.github.io</a>[3]: <a href="https:&#x2F;&#x2F;stimulus.hotwired.dev" rel="nofollow">https:&#x2F;&#x2F;stimulus.hotwired.dev</a>[4]: <a href="http:&#x2F;&#x2F;render.com" rel="nofollow">http:&#x2F;&#x2F;render.com</a>
