Day 25 of building an app a day for 30 days Built a maps app today for history buffs! It shows you what happened in history wherever you are in the world in that exact spot youre standing Not just events but buildings, streets, vanished structures etc You can scrub backwards to any time period you want using the slider and save places you wish or follow a walkin route that strings together nearby entries into a sort of "guided tour:) The entire world couldn't be completed in just one day ofc but Im planning to expand it!

Claude Code tip: before it writes any code, make it interview you 1 question at a time, multiple choice questions, until it can say back exactly what you want beat every prompt trick i've tried

the best app ideas on the internet are sitting in r/SomebodyMakeThis and nobody builds them the demand is right there

whats a tiny app/tool you built just bcoz something annoyed you? mine was an expense log you can open really fast and just type "lunch 12 usd". no bank login, nothing fancy Its so funny that i end up using my tiny builds much more than the larger projects lol

If your posts stopped showing up in X search, check this before you assume youre shadowbanned (like i immediately did) since april the Latest tab hides the last 7 days for some searches search "from:yourhandle since:2026-10-17" and open the Top tab instead all of mine were there..🙃

Hot take: claude code can carry a big app perfectly fine You just gotta write a comprehensive plan down before it starts and keep to it

Haiku 5.5 is 40x cheaper than Opus 5.5 $0.10 vs $4 per million tokens in, $0.50 vs $20 out BUT prompts over 100k tokens cost 5x more on Haiku so the job for it should be short and boring like searching files and running tests etc. I try to keep the long context work on the big one

My simplified setup for shipping 10 apps with Claude in 1 week: 1. one session per app, each in its own git worktree so they cant touch each others files 2. auto approve anything that stays inside the project folder 3. hard stop on anything that spends money 4. a Claude.md in every repo with whatever it kept getting wrong 5. a fresh session at the end with one job: break in and red team my build 6. ship when perfect all 10 repos are opensource bcoz they were made for people who asked for them on reddit or X

Had Claude write out hundreds of sound laws so i can see what a made up english word would have looked like 6000 years ago yes i'm a huge language nerd🤓easily one of the best use cases of AI!
