Was in between visas in Sweden up until yesterday. Visa arrived ~2pm. At 2:20 I had a flight booked and surprised some friends in Berlin after work. Probably the quickest packing and the most on-the-go I've been recently lmao


First time having a Cellular Watch and… yeah, being able to go run and gym without my phone is a no-way-back thing. Specially if I already download all my songs and such.


Anyone knows how to hide the "scroll indicator"-like view that Apple adds when using the Digital Crown via the ".digitalCrownRotation" modifier? Seems like it should be possible, but I can't figure it out an official way.


Stockholm is big enough that it wants to cosplay as a big city but small enough that you see the same people on the same parts of town regularly.

This took 23,560 Veo 3 credits in generations to make and get perfect That equates to $235.60 If we had shot this in real life, it would have cost thousands with a location, actress, gear, crew, etc ~250k impressions at ~$0.001/impression is insane. AI is changing the game.

Having strong, precious little opinions on particular programming languages will drag your career down. Be eager to pick up whatever tool your employer uses and ship what’s needed.
