@SpaceX I use to play this song on repeat whenever I needed a deep focus session during my final year engineering exams. This will make a cool dynamic desktop background...

@elonmusk I wonder if the car is still red... how much would exposure to unfiltered sunlight have damaged the paint job and upholstery by now?

Another reminder not just to know the ancient stories, but to know them by heart - tell them to others, participate in them actively.

@elonmusk @grok what makes the V3 satellites a "game changer" compared to the older satellites?

@VigilantFox Changing a variable in a complex system that you know nothing about will seldom have the effect you are hoping for. Often it will have the opposite effect.

Joe Rogan's wildlife biologist guest goes on a "f*cking tirade" about how the Gates Foundation "absolutely collapsed" one of Africa's most abundant fisheries that feeds millions of people, all in the name of "avoiding malaria." The more he talks, the angrier he gets. FORREST GALANTE: "Do you know what they did fucking in the Cahora Bassa Delta with their mosquito nets?" ROGAN: "No. What'd they do?" GALANTE: "Dude, I'm gonna go on a f*cking tirade here." ROGAN: "Please do." GALANTE: "Okay, so the Bill and Melinda Gates Foundation decided that there was too much malaria in Africa, right? Which you and I could probably agree with. Malaria is bad. So what did they do? They gave all of these people living in tribal villages. "I totally pirated your thing. I'm sorry, but I'm gonna go on a fucking rant here. They gave all these people living in the Cahora Bassa Delta, which is the breadbasket of the Zambezi Valley, meaning, like, where more fish are born. It's a nursery for fish. Right. Not just there, but this is a good micro example. "They gave millions of mosquito nets out to all these people to 'avoid malaria.' Guess what the people who are starving to death did with their mosquito nets? They fished with them. They fished with them. Mosquito net has a hole that is so small that a mosquito can't get through. So guess what? "These mosquito nets now indiscriminately catch tiny baby fish in areas like Cahora Bassa, where the fish go to breed and reproduce and populate. So now all of a sudden, you have thousands and thousands of people that have been handed nets that have been living one way for hundreds of thousands of years. "They don't give a sh*t about malaria. They have their own way of dealing with malaria. They sit in smoky huts at night, they sleep with a campfire. Everything else, yes, they still get malaria, some of them, but they deal with it their own way. Bill Melinda Gates Foundation come in, hand out millions of mosquito nets, absolutely collapse the entire population of fish that feed millions of people. "Because these people just take the nets and fish all the baby fish out so that those fish don't grow up to make substantial protein sources. So now these wonderful 'philanthropists' that have given out millions of nets, have destroyed an ecosystem, crashed a fish population and created widespread hunger for people that otherwise had plenty of resources, all because they were trying to 'help' with their mosquito nets." ROGAN: "Oh, God." GALANTE: "It's just like. It's a f*cking disaster, dude. They've taken such a rich and important part of Africa, one of the most abundant freshwater fisheries in the world, and destroyed it. Because they're 'helping' by handing out mosquito nets." ROGAN: "Good God." GALANTE: "Yeah, I know. Sorry. I told you I'd go on a rant, but it's like, it's so bad what's happened over there. And they're still giving out mosquito nets, by the way. And you literally watch these guys line up, take a mosquito net, and it never goes in their house. It goes straight to catching fish that are this big [tiny] for them to eat." ROGAN: "Oh, God…"

Criticize @SpaceX all you want, but remember they fly actual spaceships doing actual space missions, in actual space! and on top of that they broadcast every second of it live. Rocket science has always been synonymous with extreme difficulty. And they make it look easy.

@DrJohnVervaeke The thing is you need to aim at a becoming... you define the best/most meaningful goal for yourself. During the becoming you will make mistakes and learn (what gets you closer to the goal and what does not). And when you start to accumulate *victories" meaning becomes apparent.

Determining the meaning of your life by purpose is actually really dangerous. Why? Because most people think of purpose as something which you're working towards (some ultimate goal). That's a very dangerous way of framing meaning: - If you never reach it, your life was meaningless - And if you do, the sense of meaning often vanishes once it’s achieved There is something more important: Orientation Purpose can be very egocentric (what I most want to have) whereas orientation is reality-centric: What do I most need to be in order to be in touch with reality...to be deeply in touch with myself (with other people) and with the world?

@elonmusk I do wonder how this will be built and where all that material will come from. We ultimately need to set up mining operations on the moon. Even if that is possible do we even know where to dig???

Some of the engines didn’t start, triggering an automatic launch abort. Now offloading propellant. Next launch attempt hopefully in a few days.

SpaceX just announced that they will be deploying V3 Starlink satellites for the first time during their 13th Starship test flight next week! Six of the satellites have been modified with a suite of cameras to scan Starship’s heat shield and transmit imagery. Summary of every major upgrade and modification @SpaceX says it's made for the upcoming test flight: • More robust stage separation flip sequence to prevent the booster from rotating off course. • Hardware upgrades to improve Super Heavy Raptor re-light reliability during the boostback burn. • Updated engine alarms and abort logic for multi-engine flight conditions. • Starship propulsion system hardware and operational changes to address the Flight 12 engine-out issue. • First deployment of 20 Starlink V3 satellites with laser links, deployable solar arrays, and antennas. • Six Starlink V3 satellites equipped with cameras to inspect Starship's heat shield after reentry. • White-painted heat shield tiles added as simulated missing tiles and imaging targets. • New heat shield tile designs and attachment mechanisms, including tests on the aft flaps and aft skirt. • Load-sensing heat shield tiles to measure stresses during flight. • Higher dynamic pressure ascent profile to stress-test the heat shield and increase payload capability. • Planned in-space Raptor engine relight test. SpaceX: "For the first time, Starship will carry V3 Starlink satellites to space, which aim to greatly expand the network's capacity and user speeds. As part of this initial test, Starship is planned to deploy 20 satellites which will extend solar arrays and antennas and will attempt to connect with ground stations in South Africa and the larger Starlink constellation via high-capacity lasers. Six of the satellites have been modified with a suite of cameras to scan Starship’s heat shield and transmit imagery down to operators to continue testing methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test."

SpaceX has officially announced that they are targeting Thursday, July 16th at 6:30 PM ET for their 13th Starship test flight, and the second V3 test flight. The upcoming flight will aim to complete similar objectives targeted on the previous flight test, which debuted the Starship and Super Heavy V3 vehicles, while also carrying next-generation Starlink V3 satellites for the first time. The booster’s primary test objective will be executing a successful launch, ascent, stage separation, boostback burn, and landing burn at an offshore landing point in the Gulf of America. There have been several modifications to hardware and software to address issues seen on the previous flight.

@RobertGreene When pursuing a goal we can pull energy from a few places. First MOTIVATION...it gets you started. Then DETERMINATION keeps you moving... Being DISCIPLINED helps to keep your aim in mind and finally it is the WILL that makes you execute for extended periods of time.

Do not be afraid to exaggerate the role of willpower. It is an exaggeration with a purpose. It leads to a positive self-fulfilling dynamic, and that is all you care about. See this shaping of your attitude as your most important creation in life, and never leave it to chance.
