You’re given $2m. You have 20 minutes to spend it. You can’t spend it on cars, airplanes, yacht or a house. You can’t spend it on golds or diamonds either. What will you buy?

Look at this shot from La Haine (1995). Watch it again and try to figure out how it was filmed.

@3SkullJoe You should be a monster and learn how to control it. "It is better to be a warrior in the garden than a gardener in a war". To be a warrior in a garden is to cultivate strength without losing wisdom. To be a gardener in a war is to be powerless; a victim of ideals.

I took delivery of a beautiful new shiny HW4 Tesla Model X today, so I immediately took it out for an FSD test drive, a bit like I used to do almost daily for 5 years. Basically... I'm amazed - it drives really, really well, smooth, confident, noticeably better than what I'm used to on HW3 (my previous car) and eons ahead of the version I remember driving up highway 280 on my first day at Tesla ~9 years ago, where I had to intervene every time the road mildly curved or sloped. (note this is v13, my car hasn't been offered the latest v14 yet) On the highway, I felt like a passenger in some super high tech Maglev train pod - the car is locked in the center of the lane while I'm looking out from Model X's higher vantage point and its panoramic front window, listening to the (incredible) sound system, or chatting with Grok. On city streets, the car casually handled a number of tricky scenarios that I remember losing sleep over just a few years ago. It negotiated incoming cars in tight lanes, it gracefully went around construction and temporarily in-lane stationary cars, it correctly timed tricky left turns with incoming traffic from both sides, it gracefully gave way to the car that went out of order in the 4-way stop sign, it found a way to squeeze into a bumper to bumper traffic to make its turn, it overtook the bus that was loading passengers but still stopped for the stop sign that was blocked by the bus, and at the end of the route it circled around a parking lot, found a spot and... parked. Basically a flawless drive. For context, I'm used to going out for a brief test drive around the neighborhood to return with 20 clips of things that could be improved. It's new for me to do just that and exactly like I used to, but come back with nothing. Perfect drive, no notes. I expect there's still more work for the team in the long march of 9s, but it's just so cool to see that we're beyond finding issues on any individual ~1 hour drive around the neighborhood, you actually have to go to the fleet and mine them. Back then, I processed the incredible promise of vehicle autonomy at scale (in the fully scaleable, vision only, end-to-end Tesla way) only intellectually, but now it is possible to feel it intuitively too if you just go out for a drive. Wait, of course surround video stream at 60Hz processed by a fully dedicated "driving brain" neural net will work, and it will be so much better and safer than a human driver. Did anyone else think otherwise? I also watched @aelluswamy 's new ICCV25 talk last week (x.com/aelluswamy/sta…) that hints at some of the recent under the hood technical components driving this progress. Sensor streams (videos, maps, kinematics, audio, ...) over long contexts (e.g. ~30 seconds) go into a big neural net, steering/acceleration comes out, optionally with visualization auxiliary data. This is the dream of the complete Software 1.0 -> Software 2.0 re-write that scales fully with data streaming from millions of cars in the fleet and the compute capacity of your chip, not some engineer's clever new DoubleParkedCarHandler C++ abstraction with undefined test-time characteristics of memory and runtime. There's a lot more hints in the video on where things are going with the emerging "robotics+AI at scale stack". World reconstructors, world simulators "dreaming" dynamics, RL, all of these components general, foundational, neural net based, how the car is really just one kind of robot... are people getting this yet? Huge congrats to the team - you're building magic objects of the future, you rock! And I love my car <3.

@WorstGenHQ Xebec killed his parents and the rest of the Davy clan that was turned without a slight moment of hesitation. Do you think Roger or Luffy would do that?

@sporadica An important key to success is discipline. If discipline is ingrained in you from an early age so deeply that it becomes second nature, then it’s like having a superpower.

i have met multiple super successful and impressive women recently that are former ballerinas and are now in tech and i must say i am noticing a trend here

Is tennis the perfect sport? - It's exciting for 1 hour and then gets tedious. A perfect amount of time for daily exercise - The court blends in to the landscape and doesn't transform the landscape like a golf course - no teammates that expect something of you or to tell at you. - using a tool, very human - can play against a man or woman - focus on rotating the body and the transverse plane. Improves balance and coordination - you're outside - the satisfaction of a smooth stroke
