AI field notes for solo builders. Tools, systems, automation, and small bets.

MacBookで一番後悔しやすいのはCPUでもSSDでもなく、統合メモリ。 購入後に増設は不可。16GBもChrome/Cursor/Docker/ローカルAIで意外とすぐ埋まる。選ぶべきは今ではなく2〜3年後に必要な容量。

GPT-5.4, 5.5, 5.6은 뭐가 달라질까? 핵심은, 사람이 중간에 개입하는 횟수가 줄어든다는 것. 5.4는 복잡한 작업을 실제로 수행하기 시작했고, 5.5는 계획·테스트·수정까지 더 잘했고, 5.6은 적은 토큰/도구 호출로 UI를 다듬고 여러 에이전트를 병렬로 움직입니다.

If you give kids a smartphone, they’ll usually watch videos. But there’s an app that turns a “watching tool” into a “making tool.”

Vibecoding will change hiring too. “Did you build it?” “Did users actually use it?” “How did you handle problems?” “Can you spot when AI is wrong?”

VACUUM? Don’t just clean your house—clean your database too. With vibe coding, logs, alerts, and AI job records quietly pile up. "DELETE" doesn’t तुरंत reduce PostgreSQL disk usage.

GitHubのコミットは残るのに、「なんでこう作った?」という文脈はすぐ消える。 Vibecrewのkimyoungwopoさんが作る「각자코딩」は、短いメモと振り返りを足して、開発の過程を作業日誌として残すアプリです。 - 何を作ったか - なぜその方法を選んだか - どこで詰まったか - AIに何を頼んだか - 何を学んだか AI開発ほど、判断は残りにくい。 「각자코딩」は、その文脈を自分の成長記録に変えます。

Domains should be bought after MVP validation.” That’s only half right. Business-wise, build first and confirm demand. Buy a domain for every idea, and you end up with more unused domains than products.

5 things that actually changed with vibe coding. No more memorizing syntax for every language. No more reading docs end to end. I try new tech first. I don’t copy error lines one by one.

바이브코딩할 때 자주 하는 실수 5가지. 1. 에러마다 새 채팅 2. 확인 없이 계속 승인 3. 백업 없이 “원래대로” 4. 같은 에러를 프롬프트만 바꿔 반복 5. 화면 뜨면 끝이라고 생각 제일 무서운 건 에러가 아니라, 어떻게 돌아가는지 모르는데 잘 되는 순간.

People say they made money with vibe coding, but closer up, course sellers stand out more than product makers. What they’re selling may be less tech and more the hope that “one app could change my life.”

Vibe-coding quantum leaps need two skills: 1) Generate ideas: spot pain points, make them business. 2) Design systems and split features; coding depth isn’t required. Learn foundations step by step with VibeCrew. 🚀

130 crew members have gathered in Vibe Crew. What matters more than the numbers is growing a core crew that truly helps each other. Post first, leave a warm comment, and try the apps yourself with honest feedback.

5 AIs = “multi-agent collaboration”? Or 5 repeats of one question. 2,965-session model: • Claude: research/split • Gemini: counter/options • Codex: build/check • Hermes: plan/run Key: roles, approvals, handoffs,

Ever wonder if JWT/JSON gets stored server-side when pasted into a web tool? Vibecrew’s CKApps made 27 browser-only tools: JSON, JWT, SQL, regex, Cron, Markdown—no server transfer. Firebase hosting setup: ~2h. 😮

Cursor & VS Code: native, right? Both use Electron—web tech for desktop. Should every app use it? Complex: Electron. Light: Tauri. Mobile: Flutter. Vibe coding: choose by app, not language.

Vibe coding needs no PC. No MacBook on vacation, feedback on finding notifications led me to Codex Remote on my phone. By dawn, inbox was live. 😂 Mobile fixes and deploys. Feedback changes services. Thanks, crew! 🙇

Downloaded it… where saved?” Searching for a KakaoTalk PDF or old Excel file? The default app needs the location; this one finds and sorts documents and images on your phone by type.

Am I ready for retirement now?” A VibeCrew member built a service that shows whether you can cover your desired living expenses after retirement by entering just a few items.

Building SaaS with vibe coding hits one big hurdle: global payments + subscriptions. Got early access to “Unifi Pay Direct” from LINE NEXT.

SQLite3 for a simple MVP? Yes—if you're starting small and fast, it's enough. Single-file, but not a toy DB. Ask AI for: ✅ WAL mode ✅ busy_timeout ✅ foreign keys ✅ persistent volume

No modeling at all, yet a cute Claude moves on the map. 🤖🌍 A Vibe Crew member used Opus 5 + Anthropic Economic Connector to build the interactive web “Claude Atlas.”

Vibe coding is lonelier than you’d think when you do it alone. Build alone, think alone, get stuck alone, and have nowhere to get feedback after launch. That’s why Vibe Crew exists.

AdSense got rejected again after I reapplied. I made "goodtek.xyz" a main hub for my services and posts, but Google seems to see it as “low-value content.”

It’s not that we can’t make apps—it’s that we’re taking on too much. 😂 A Vibe Crew member is building 3 “I made it for myself” apps from everyday pain points: 📚 library search ⏱️ Togedoro 🍡 easyorder

Apps can be built alone, but it’s hard to build them well alone. Feedback is needed before, during, and after launch. In the end, feedback grows the product.
