Title: 21 Beautiful Christmas Markets in Hamburg
1st Place: A wine shop that serves Glühwein
This is why I built Franzbrötchen, there are ads everywhere, and it's too hard to find the information you actually need.

OpenAI lost about $10 billion last quarter. For comparison, Apple's failed car project had 5.000 workers, ran for 10 years, and lost about the same amount in total.

Custom Product Pages are perfect for Franzbrötchen, but I wish Apple would allow you to add keywords for each custom page instead of limiting you to picking from the existing keyword pool.

Over three years ago, I had an idea for an app but knew little about iOS development. Since then, I've released 9 apps while gathering resources and refining the concept. In the past few months, I've spent 100+ hours building it and just submitted it to the App Store. And the best part? It's free.

Looks like OpenAI started to limit the free usage of ChatGPT. Well, someone has to pay for the compute I guess.

Many people, even die-hard Apple fans, believe Apple is falling behind in the AI race. But I think Apple is simply playing the long game, as it always does. If the AI bubble is going to burst, it’ll be Apple Silicon that pops it. www.apple.com/newsroom/202...
Apple unleashes M5, the next big leap in AI performance for Apple silicon

This is the problem with the media. They became a free marketing tool for companies.
It bothers me to no extent that the media plays how Klarna whistles
Klarna wants to the headlines to say "AI-enabled Klarna"
It would have halved its workforce without AI because it overhired 2x in 2020-21 and never corrected till now
But this is how they get front pages
