@0xfuckoff @TSLA_inside_ When FSD fails, it flashes a red warning “Take over NOW!” and jerks the wheel back to straight ahead. If you’re traveling on a curved path (turning at an intersection, exiting the motorway, switching lanes) the driver *must* take over in less than 0.10 seconds OR crash.

@TSLA_inside_ How is FSD working when the lines start to fade a bit more?

Finally. After 18 months of patience, FSD is officially approved and live in the Netherlands. I’ve been driving with it for 2 days now. And the experience is on another level. It feels like the future unfolding in real time. The precision. The intelligence. The confidence of the system. This is not incremental progress. This is a clear step forward in how mobility works. Huge thanks to Elon Musk and the entire AI team at Tesla. From a professional perspective, this shows what is possible when software, data, and real-world deployment come together at scale. The question is no longer if this will take over. The question is how fast it will expand. This is a turning point. @elonmusk

@Habubrats71 The density/strength chart shows CFRP reaching the strength of titanium at lower density. Have material scientists developed RP (epoxies) that can withstand the heating at Mach 3+? (FWIW, SpaceX’s Starship originally was to use carbon fiber, but switched to SS for heat)

The SR-71’s speed was not limited by the power of its engines. It was limited by the heat its structure could withstand. Titanium makes up 93% of the SR-71s structure. A material that had never been truly utilized to its full potential until the SR-71 came along. Each SR 71 was handmade. That means everyone of the Blackbirds were ever so slightly different. The men that flew the SR’s had their favorites and then there were the hangar queens that no one liked to fly.. The reason why titanium was so expensive was the process to make it usable. The first reliable process to produce chemically pure titanium was developed in the 1940s. This process made the SR-71 possible. It begins by first converting the titanium dioxide to titanium chloride. How do we convert the Titanium? To do this titanium dioxide is mixed with chlorine and pure carbon and heated. Any oxygen or nitrogen leaking in will ruin the process, so this has to be done in relatively small batches in a sealed vessel. Once this process is complete, we have Titanium Chloride. We then need to purify the Titanium Chloride from any impurities in the titanium ore through distillation. Where we heat the product and separate titanium chloride using its lower boiling point. This Titanium Chloride vapor is fed into a stainless steel vessel containing molten magnesium at 1300 kelvin. Titanium is highly reactive with oxygen at high temperatures, so the vessel also needs to be sealed and filled with argon. Here the Titanium Chloride reacts with the magnesium, which itself is an expensive metal, to form titanium and magnesium chloride. At times the engineers were perplexed as to what was causing problems, but thankfully they documented and cataloged everything, which helped find trends in their failures. They discovered that spot welded parts made in the summer were failing very early in their life, but those welded in winter were fine. They eventually tracked the problem to the fact that the Burbank water treatment facility was adding chlorine to the water they used to clean the parts to prevent algae blooms in summer, but took it out in winter. Chlorine as we saw earlier reacts with titanium, so they began using distilled water from this point on. They discovered that their cadmium plated tools were leaving trace amounts of cadmium on bolts, which would cause galvanic corrosion and cause the bolts to fail. This discovery led to all cadmium tools to be removed from the workshop. Converting Titanium for the SR-71 is really slow This reduction reaction is extremely slow, between 2 and 4 days. It’s pretty clear that titanium is expensive and extremely difficult to work with. But without Titanium and the SR-71, we wouldn’t be where we are today, talking about the fastest, air, breathing airplane in the world. You can read the full article here.

@jeremymaluf In 2015 the Chronos Smart Disc added “smart” notifications to any watch. It provides a lot of the functionality you’re proposing. Unfortunately, @WearChronos didn’t find the product-market fit they hoped for and went out of business. hodinkee.com/articles/chron…

Free $1B product idea for anyone who has the resources/experience/time to build a luxury-hardware brand Had this idea in the shower. Want it so bad. But not gonna drop everything rn to make it. So I quickly 3d-modeled it hoping someone else will make it and let me buy it

@jeremymaluf The Sinn Dual Strap system offers a decidedly low tech approach to wear both a mechanical and smart watch simultaneously. watchesbysjx.com/2016/08/introd…

very proud of this one

@YoBenCohen @MagnumGlobal Should we still buy Ben & Jerry's ice cream to support you, or would that just further Unilever's pusillanimity?

After 47 years, Jerry has made the difficult decision to step down from the company we built together. I’m sharing his words as he resigns from Ben & Jerry’s. His legacy deserves to be true to our values, not silenced by @MagnumGlobal #FreeBenAndJerrys

@lrozen Posting this for no particular reason …..

Trump has no public events scheduled all weekend. Don’t believe he was seen today either.

@SollenbergerRC Wow! @PressSec Leavitt just became an oxymoron. “I’m not going to reveal that … We’ve been incredibly transparent.” Harness up that brain, it’s flip-floppin’ so fast it could power NY!

Q: Who’s DOGE administrator? LEAVITT (feigning exasperation): Elon Musk is overseeing DOGE. Q: He’s the administrator? LEAVITT (feigning exasperation): No, he’s a special govt employee. Q: Who’s the admin? LEAVITT: I’m not going to reveal that...We’ve been incredibly transparent.

@MobiusMobility please have @ZacksJerryRig try out the #iBOT! Their [video](youtu.be/hxf-fIubkMs?si… ) on @scewo_official's chair reminded us what @DeanKamen started 34 years ago!

@thammadou @CaltrainAlerts @Caltrain @CAgovernor The phrase missing from this conversation is “grade separation“. It’s expensive, time consuming, and often requires use of eminent domain. It’s complicated.

@CaltrainAlerts @Caltrain=> Those situations keep happening & most of the time you have a reactive response than a proactive one. @CAgovernor this a simple example of how our infrastructure is broken.

@KyivIndependent Yevgeny Prigozhin is organizing a fighting force in Belarus now. He was publicly chastised by Putzler to further the ruse that he’s out of favor. The Russian pilots shot down were the only real losers.
