Show HN: I quit coding years ago. AI brought me back

Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn'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't written real code in years.

Fast forward to now. I'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's basically meditation for long-term investors.

The problem? Every compound interest calculator online is terrible. Ugly interfaces, ads covering half the screen, can't customize compounding frequency properly, no year-by-year breakdowns. I'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't have to be a "real developer" 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 "well, while I'm here..." and added mortgage, loan amortization, savings goals, retirement projections. Then it spiraled — BMI calculator, timezone converter, regex tester. Oops.

The AI (I'm using Claude via Windsurf) handled the grunt work beautifully. I'd describe exactly what I wanted — "compound interest calculator with monthly/quarterly/yearly options, year-by-year breakdown table, recurring contribution support" — and it delivered. With validation, nice components, even tests.

What I realized: my years away from coding weren't wasted. I still understood architecture, I still knew what good UX looked like, I still had domain expertise (financial math). I just couldn't type it all out efficiently. AI filled that gap perfectly.

Vibe coding didn't make me a 10x engineer. But it gave me permission to build again. Ideas I've had for years suddenly feel achievable. That's honestly the bigger win for me.

Stack: Next.js, React, TailwindCSS, shadcn/ui, four languages (EN/DE/FR/JA). The AI picked most of this when I said "modern and clean."

Site's live at https://calquio.com . 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?

Sequoia to invest in Anthropic, breaking VC taboo on backing rivals: FT

Sequoia Capital is reportedly joining a blockbuster funding round for Anthropic, the AI startup behind Claude, according to the Financial Times. It’s a move sure to turn heads in Silicon Valley. Why? Because venture capital firms have historically avoided backing competing companies in the same sector, preferring to place their bets on a single winner. […]

Show HN: Beats, a web-based drum machine

Hello all!

I'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'all.

It'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.

You need to listen to the cosmic horror-comedy podcast Welcome to Night Vale

It's relatively rare for a podcast to last 14 years, especially a fiction one. In fact, as far as I can tell, Welcome to Night Vale is the longest continually running fiction podcast out there. (Some will argue it's actually We're Alive, but that has taken a few significant breaks between seasons.) The story of […]
