no analytics, no ads, no crash reporting, no server. built this because i was so annoyed with existing apps charging for something that took me 24 hours to make
github.com/justingluska/yapp…
it's live on the app store 👇
apps.apple.com/us/app/yapper…
built it for myself because i talk way more than i type & figured i'd share with others bc I use this app every single day now
An interesting visualization I put together justin.fm/where-your-taxes-g…
Very interesting from @AnthropicAI about Claude text watermarks (and an API to detect AI written content in private beta right now). Would love to try this
made mapped.lol to plot your place in the world and outbid others 👀🌎
Aaaaaaand we're live!
outbid.lol
No ads. No API keys. No revenue sharing.
Just outbid your competitors to rank #1 and consider marketing done for today 🚀
mapped.lol made a website where you can claim pixels of the world and outbid eachother to replace whatever tiles in the world! :D
If you’re in your 20s (and ambitious) do everything to move to those 4 cities
Yes people will mog you for paying extortionate rents for such little comfort but who cares, you’re not everyone, you’re on a mission, you’re here for greatness
London/NYC/Paris/SF are basically the golden 4. They’re not just big cities, they’re global sorting machines. People move there from all over the world because they want sth badly enough to accept all the downsides. The guy born in London can be lazy. But the 26yo Frenchman, Indian, American, Italian, Nigerian, Lebanese etc who voluntarily accepts the tiny flat, shit commute and absurd rent to be there has already self-selected pretty hard
And that selection compounds. I felt it instantly moving from my hometown in France to London. Growing up I was always “the ambitious one” in my friend group. Then you arrive in London and suddenly you feel extremely average. Everyone is trying to do sth. Completely changes your reference point for what a normal person can achieve
The other thing is just how many serious games are happening at once. If you know at 22 that you’re going to be a semiconductor engineer forever, maybe there are better specialised places. But most ambitious 24yos have absolutely no clue what game they’ll eventually want to play. In London/NYC/Paris you can accidentally become friends with people in PE, startups, politics, law, media, fashion, pharma, academia etc. Your finance friend dates someone in fashion, their roommate is building a startup, you meet someone in politics at dinner. Suddenly 5 completely different lives feel plausible
That’s insanely valuable when you’re young precisely because you don’t yet know which people / industries / opportunities will matter to your 34yo self
SF is the weird exception because it’s basically one giant concentrated bet on tech/AI. Much narrower than the other 3, but that game is so asymmetric rn that it deserves its spot. If you want to build at the frontier there’s probably no other place where your reference class changes that aggressively
And yh everyone keeps saying the internet made geography irrelevant. Maybe for information. Definitely not for trust/friendship. Anyone can learn from the same people online now, send the same cold DM, follow the same accounts. Much harder to replicate being the guy someone has had 20 dinners with, worked with, travelled with, introduced to friends and randomly bumped into for 5 years
When you’re 24 and nobody knows who tf you are, geography can do a lot of the work for you. You get invited because your colleague knows someone. You end up at a dinner because your friend needs a +1. Someone you met 3 years ago leaves and starts a company. Another moves to NYC. Another becomes a partner somewhere. Most of the ROI is completely impossible to predict upfront
Basically before you have your own gravity, borrow the city’s
At 45, if you’ve built the company / reputation / money / audience / network, you can go live in Tuscany, Mallorca, South of France or wherever and people will come to you. At 24 no one is coming lol. You should probably be where everything is happening
And tbh if you have the ability to move I wouldn’t spend 3 years waiting for the perfect job / apartment / timing. Get the shitty room, accept being poorer for a while, figure it out once you’re there. Your 20s are probably the cheapest years of your life to tolerate inconvenience anyway
You can optimise sqm, weather and comfort later
At 24 I’d rather maximise how many possible lives are available to me

I've been the 'travel friend' for as long as I can remember.
I built @withautopilot 3 years ago to save money on my own flights.
It feels incredible to put money back in our customers' pockets.
You're LOSING MONEY if you don't travel @withautopilot
I just saved $1,200 on my flight using @withautopilot.
This app is literally free money. Put in your flights and get $ back.
@SamHollander_ was my roommate.
I watched him start from nothing and build this into a huge biz, saving ppl thousands a day.
Not using this is stupid.
