Claude Code has changed our dev process, starting around June of 2025 when we learned about it from a presentation in the o'reilly safari webinar, can't remember the guy who presented, but it was really good.

When a seasoned founder sells their company, they are transformed from a highly productive member of society into a depressed money manager. Meanwhile, the goods and services of their former company are degraded by the loss of its most effective employee. The former founder is deterred from starting a new business by the seemingly high returns generated by their money, which will for years dwarf the cash flows created by the new business. The founder is only snapped out of this stupor by the realization that the person who founds a successful company will never be satisfied only by watching numbers going up and down on a computer screen.

I guess it's time to show off what we've been working on. This has been an 8 year project in the making. I picked a completely random unit called Spud Muffin drilled by Devon in Eddy county. Video 1 / 12 - Find the wells. Filter down to active Devon wells in Eddy. Further refine with the drawing tool and filter spatially. No limits whatsoever on mapping and filtering capabilities, can handle 6,000,000 wells rendered on the map.

Like I’ve said for years, we desperately need autonomous cars because we’ve had driverless cars for a decade.
This shows you how using your cell phone while driving can lead to an accident.

Apologies for the TLDR, but when you step back, it is kind of wild what we’ve all lived through over the last five years. No wonder so many young people are anxious about the future—the ‘disturbance in the force’ feels stronger by the day. I don’t have any grand takeaways other than this--the world could use an immediate course correction in the direction of boring--or we may really need those Mars rockets sooner than expected. One thing is for sure--Israel is making a compelling case for Golden Dome. • A once-in-a-century pandemic shuts the world down. No matter how you view it in hindsight, both allies and adversaries were nearly unified in halting the global economy and banishing society to lockdowns and high-pressure mask & vaccination campaigns. • We tried to print our way out of the system shock, triggering the most euphoric markets since the dot-com bubble—pre-revenue IPOs reappeared for some reason and people forgot that good companies generally don’t SPAC. • The digital revolution kicked into overdrive—work-from-home, virtual education traumatized parents, Zoom cocktail parties, Peloton, DoorDash and MS Teams---probably the most painful development. • Civil unrest emerged alongside deepening social and political divides. • A disheartening end to the war in Afghanistan—trillions spent, thousands of lives lost and the Taliban is still running the show. • Market euphoria gave way to historic inflation. Interest rates shot up to cool things down. The tide went out, and the “shitcos” failed. Centralized crypto exchanges gambled customer deposits. Hedge funds weren’t hedged. VC-heavy banks like SVB collapsed, triggering a temporary panic in the regional banking system. The big banks… got even bigger. • For the first time since the Soviet invasion of Afghanistan, a nuclear superpower launched a full-scale invasion of a neighboring country. The West isolates Russia, and we witness a new asymmetric dynamic in warfare--cheap drones, missile swarms, all playing out in real time on social media. • The metaverse and Web3 died quickly as the “Magnificent Seven” lead a market rebound on the promise of AI. • China closes gaps--and maybe pulls ahead--in some of the most strategically important technologies. They tolerate risk, aren’t afraid to steal good ideas and make them better--and operate with a culture that—for all its flaws—just goes out and does big things without dragging decades of baggage behind it. • Hamas launches a surprise attack on Israeli civilians, takes hostages and triggers a war that pulls in Iranian proxies like the Houthis--disrupting global shipping lanes and igniting a politically charged humanitarian crisis. • Political winds shift again. A former President—also the frontrunner—is shot in an assassination attempt, the first since Reagan. Thankfully, he survives and is now our 47th President. • The Pakistani and Indian Air Forces engage in the largest air-to-air exchange in decades. China’s latest fighters and missiles see combat success against contemporary French aircraft—signaling what many already knew--China’s military is approaching peer status. • Israel launches the most sophisticated and devastating air campaign since Desert Storm—targeting Iranian military and scientific leadership, degrading air defenses, missile systems and nuclear infrastructure..and the conflict may just be getting warmed up. All in just five years... Hopefully our defense and policy leaders are paying attention and making some course corrections. Congressional leadership is mostly well-intentioned, but often fights for expensive job programs--exactly the kind of thing an over-consolidated defense industry encourages--even as we stare down an unsustainable $36 trillion national debt. That’s how you end up holding a fleet of battleships during the advent of the aircraft carrier.... Only this time, the analogy breaks down--because as a nation have forgotten how to build ships. So instead, we will have $300 million fighter jets we can’t afford, arriving a decade too late, in quantities that may not even matter—disrupted by million-dollar, hypersonic, laser-equipped drones that our adversaries will likely produce at scale. Until, perhaps, the dark horse Skynet T-1000 shows up. This is the time--especially in such a politically charged environment--when we need to be finding more ways to come together instead of moving farther apart. A time to be rooting for America and our leadership, not betting on the next Polymarket catastrophe. Because if the next five years look anything like the last, military parades and trade imbalances will be the least of our problems.

Sweet heavens. The FSD situation on the Legacy Model S (2019) is getting very frustrating. 12.6.3 doesn’t suffer from a lot of the atrocities that 12.5.4.2 did, but it’s terrible in entirely new ways. It acts absolutely insane one moment, then excruciatingly timid in others. On city streets, it stops in the middle of the street AFTER committing on unprotected lefts and right turns on red. It runs red lights (usually after already stopping,) it won’t proceed on green lights. It is indecisive about accelerator and brake usage — often braking and accelerating many times in the span of a couple of seconds (12.5.4.2 did that also.) Although I’m giving examples of city streets, don’t worry — end to end on highway acts mostly just as bizarre. It will drive with the blinker on for half a mile, hug lane lines, abort lane changes several times until it finally changes so close to the gore that if it aborts again, it will crash into the attenuator at 70+ mph. It does this in heavy traffic and it does it in light traffic. It cuts across lanes and gores in so many awkward ways that I’m not even sure that it knows which lane is which — to the point that I actually freak out thinking that FSD is somehow not engaged and I’m just on a straight line vector to running off the road. In heavy traffic, when traffic comes to a stop, the car will often refuse to keep pace after traffic starts moving. Often times creep along at ~10mph until there’s a gap large enough to fit a convoy of Tesla semis. For context, I also own a 2022 Model Y with HW3 running 12.6.3, and a 2024 Cybertruck with 13.2.6. Both of which are rock solid. I struggle to even tell the difference between 12.6.3 on the HW3 Model Y and 13.2.6 on the Cybertruck. Robotaxi feels right around the corner on those vehicles. The thing is, I can tell that both city streets and highway on the legacy Model S are siblings of v13 and 12.6 on HW3 Model Y. But it feels like there is a heuristic layer running on top of it much like 12.5.5 felt like on the Cybertruck. Only this is much worse. We really need this to be addressed. But at this point, from a technical perspective, I am also curious: what the hell is going on with this FSD stack? Can we get a comment from @aelluswamy? I’ve gone the last 3+ years thinking that the cameras and FSD computer on my Model S and Model Y were identical. (@greentheonly.) So is this literally just camera placement differences? Is the hardware for the throttle/steering rack/brake different? Is this the “new controller?” Not much makes sense here. I really didn’t think it could get much worse than 12.5.4.2. And, while it does do many things more naturally than 12.5.4.2, this version may be the least safe feeling version of FSD that I’ve ever experienced. And I’ve been using FSD since ~August 2021 (v10?) I’ve been patient about this since early October-ish when I got pushed off of 12.3.6 (RIP, old friend.) But it’s really time to start making noise about this. I kept the Model S when I got the Cybertruck because it feels like a classic car. One I need to own. I also would like my relatives to have a car when they come visit. I was hoping to use this vehicle to loan to friends and family who haven’t experienced FSD. I’ve never been less confident putting someone behind the wheel of FSD. Not the way I wanted this to go. It hurts being this critical while also knowing how much progress has been made on other models over the last 6+ months. @teslascope you’ve asked about FSD experiences on the Legacy S before. If you’re interested in helping to get this out there it would be much appreciated. I’m trying hard to be comprehensive here.

Just went for a drive after the DAS reset. The drive was arguably better, but pretty much all the same issues were present still. They felt subjectively better this drive. Probably just standard FSD variability, but I will collect more of my experiences over the next few drives. I did take some videos. I may compile some highlights and post.

I can’t believe I’m saying this 12.6.3 is the worst version of FSD for a 2020 model S legacy Driving over center lines, constant slow downs to 5 mph in 35, jerky controls. Ugh. I hated 12.5.4.2 but at least it was kinda useable. This is atrocious can we downgrade. @teslasi
