X AI ALGORITHM UPDATE (BIG ONE) 🚨 X updated their open source algorithm yesterday and the biggest number in it is gone: copy link went from 20 to 0 points. Small accounts should focus on: posts people like, reply to and stay on (so stop counting on link copies) tl;dr: - on Nov 13 X's open source code set the score for copying a post's link to 0 - copy link: 20 → 0 - it was the top score in the whole system, 4x a reply - the code also names a "copy link bait" spam check - likes (0.708), replies (5) and DM shares (5) didn't move full details: - The number that's gone Since I started reading X's open source code in August, one number sat at the top: 20, for someone tapping share and copying your post's link. Nothing else came close. As of the Nov 13 release, it's 0. X still guesses who'll copy your link. It just multiplies that guess by 0 now. X didn't explain it. It's just what the code says. (I check the open source algo daily with Claude and share updates with you) - Cross it off your list My own checklist called copy link the biggest number. Last week's post said it too. It was true then. It isn't now. If you saved that list, cross that line out. - The "copy link bait" check X's code now mentions a spam check called "copy link bait". In the code it adds a spam label to the post, and that label already keeps a post out of strangers' feeds. It only shows up in a test, so I can't see if it's running or how strict it is. My read: X saw people baiting link copies, so it turned the score off and built something to catch the bait. That's a read, the code doesn't say why. - Why that matters if you're small If your plan was posts people copy the link to, that plan now earns 0 in X's ranking. A copied link can still bring people in from outside X. It just doesn't push your post up anymore. What still pays: likes at 0.708 (the highest ever), people staying on your post, replies at 5 and back and forth with mutuals at 20. - Also new: photo and video tags If a post has a spam label, people you tag in its photo or video who don't follow you won't get notified. Same idea as last week's rule for replies. - What didn't change Every other score. Your new posts still get their extra push in the first 2 hours and first 200 views, and early likes still pick which one gets it. Here's a recap of what you should be doing: - aim for likes, replies and time spent, the copy link score is gone - a DM share still earns 5, same as a reply or a quote - likes sit at 0.708, never higher - time on your post keeps counting at its best rate yet - 10+ seconds after someone taps in adds 0.385 - write your replies yourself, under big accounts most of all - give people a reason to hang around your profile - in videos the opening seconds carry it, an open alone scores 0 - posts read to the end help X find you strangers - smaller accounts (below 50K) get a shot at a spot near 16 for a fresh original - early likes decide which new post gets that spot - post when your followers are awake, the push lasts 2 hours and 200 views - mutuals going back and forth earn 20, so follow back the regulars - only your originals ever get shown to strangers - like 1 and like 32 each unlock another way to reach strangers - one strong post per feed, your second only counts 62% - clips longer than 10 seconds for the video lists - a post likely to win you a follow gets +4 - give your pinned post a look, it can affect the whole account What you should NOT be doing: - counting on copy link shares, they score 0 now - baiting link copies, the code names a spam check for exactly that - a spam label also stops your photo tags reaching non-followers - AI-written replies under big accounts, "llm slop" is a flag X uses - copy-paste replies, labeled ones skip non-followers' notifications - chasing taps, 0.274 and dropping - drifting off your topic, each probable "not interested" takes 53.07 away - videos people open and leave, the open itself earns 0 - posting at 3am, it wastes the 2 hour push - expecting replies and reposts to reach strangers - an insult label, it hides that post from non-followers - earning a misinfo or low quality label, which adds a warning and locks strangers out of liking or sharing - 3 adult photos or videos among your latest 5 posts, that puts a label on you - forgetting videos get rechecked at 64 and 512 likes - one account label and strangers stop seeing you - pinning a link to a site X rates badly, that can mean a label for a week - posting your own old words again risks the copypasta flag - a low quality link plus tagged strangers reads as spam - bait for engagement, big or small it gets a label - several posts back to back, they split the same feed - hashtag piles, they do nothing - bookmarks for reach, they score 0 - hoping a 3 day old post still lands in For You, it stops at 2 days

Grok Bot summary: IAC 2026 presentation by SpaceXAI President Michael Nicolls. 🎯 The main message - SpaceX was founded in 2002 to make life multi-planetary and "extend the light of consciousness to the stars." - He said the biggest risk as constellations grow is not debris. It's satellite operators not sharing data with each other. 🌍 How Starlink grew - Starlink began in 2019 with 60 V0.9 satellites. User service started in late 2020 as the "Better Than Nothing Beta." - V1.5 added space lasers, which let the satellites link into a mesh. That's when Starlink really took off, reaching oceans, Antarctica and airplanes. - V2 (2023) has 4x the capacity of V1. Falcon launches V2 satellites 2–3 times a week, and each launch adds about 3 terabits of capacity. - V3 launched on Starship about a week before the talk. Each V3 satellite has another 10x capacity, and each Starship launch carries 20–30x what a Falcon launch does. - Starlink now has over 11,000 satellites, about 60% of all active satellites in low Earth orbit. - It serves more than 13M customers in about 170 markets, plus ships and planes. - The laser mesh means Starlink doesn't depend on local ground infrastructure. During last year's fires and power outages in Spain, it kept tens of thousands of customers and emergency responders online. 🚀 The life of a Starlink satellite - **Before launch:** SpaceX checks that deploying the satellites won't bring them close to anything else, and shares where they'll be. - **Deploy:** satellites are released below 300 km, where almost no other operators fly. - **Orbit raising:** each climb path is checked against other satellites and crewed space stations, and SpaceX publishes the satellites' positions every hour on the way up. - **Lower orbits for safety:** the original plan was about 1,000 km. Now every satellite flies below 500 km, and V3 will fly at about 350–360 km. At these heights a dead satellite falls back to Earth within months instead of staying up for centuries. 🛡️ How they avoid collisions - Each satellite makes small station-keeping moves about once a day and a collision-avoidance move about every 10 days. - Across the fleet, that's about 1,000 avoidance moves a day. - Starlink's threshold for moving is nearly 100x more cautious than the industry standard, so the whole fleet's collision risk is about the same as a much smaller constellation's. - "Ducking" moves turn the satellite so it presents a smaller target during a close pass, cutting the collision risk about 10x more. - Automated software makes these decisions, which is why Starlink tries to stay in contact with every satellite at all times. 📡 Always connected - Starship's live launch video was streamed over Starlink. - The new V3 satellites connected to the network within 2 minutes of release, because Starlink terminals are built into the satellites. Their lasers link into the mesh within tens of minutes. - The goal is to make contact right away and never lose it. 🌬️ Space weather - During a 2024 solar storm, air density in orbit jumped 5x in a few hours, which throws off predictions of where satellites will be. - Starlink is "probably one of the best sensors" for this. It measures density in real time and automatically corrects its position forecasts. 🔭 Working with astronomers - **Optical:** SpaceX tried Vantablack paint and sun visors. What finally worked was a mirror-like film that reflects sunlight away from the ground, combined with careful steering. A V2 satellite now looks about as bright as a sheet of paper. This was done with groups like the Vera Rubin Observatory. - **Radio:** working with observatories like the US National Radio Astronomy Observatory (NRAO), Starlink steers its beams and frequencies around where the telescopes are pointing. As a result, the telescopes can now observe more often. ♻️ End of life - SpaceX uses statistics to predict when parts will fail and deorbits satellites early. Many of those satellites would have kept working. - Retired satellites are steered down within weeks, not left to drift for the 5 or 25 years regulations allow. - They're built to burn up completely, and reentry is aimed over the ocean. - Of about 10,000 satellites launched by early 2026, only a few dead ones remain in orbit. The goal is zero. - "Reliability and rate go together." ⚠️ The biggest danger: other operators - Tracked debris is like obstacles on a road: if you can measure it, you can avoid it. - What you can't avoid is a satellite that maneuvers without telling anyone. Starlink has had passes as close as tens of meters this way. - Starlink has maneuvered around satellites from about 650 operators in recent months, but shares position data with only about half of them. "That number is too low." - SpaceX shares data with China's space station and some Chinese operators. Many operators don't share at all, including some in the US, Europe and Japan. ⭐ Stargaze: Starlink's own space tracking - Over 30,000 star trackers on Starlink satellites spot passing objects as streaks against the stars. - Stargaze now tracks over 17,000 objects, including about 90% of the maneuvering satellites that cross Starlink's orbits. - In one example, an untracked satellite's predicted 9 km miss shrank to about 60 m after it maneuvered toward Starlink. Stargaze caught the move and the Starlink satellite dodged in time. - He said it's still no substitute for operators sharing their plans in advance. 🤝 The ask: share your data - SpaceX runs its own space safety data platform, and over 100 operators have signed up. - Operators can upload their satellite positions and check them against Starlink and against Stargaze tracking. - His message to every operator was to join the platform and share their positions. 🧠 StarMind: AI compute in space - StarMind is SpaceX's planned AI satellite constellation, starting launches and scaling next year. - The goal is to move AI compute off Earth. He expects StarMind to drive demand for Starship launches the way Starlink did for Falcon. - On the ground, SpaceX is building over 2 GW of compute in Memphis. He said AI demand will be nearly limitless, and Earth's resources make that hard to keep scaling there. - In space, the satellites run on solar power and shed heat through large radiators. - Each satellite is simpler than a Starlink: basically a computer with big solar panels and radiators. - Each one has about 250 kW, roughly one NVL72 rack of compute. - They'd fly in tight clusters of about 10 satellites linked by about 10 terabits of bandwidth, then connect to Starlink. - SpaceX has filed for up to **1 million satellites**, in low-inclination and sun-synchronous orbits. Building them could mean thousands of satellites a week. - New challenges include much higher reliability and redundancy, flying in close formation, and micrometeoroids. Dead satellites might be sent away from Earth instead of burning up in the atmosphere. 🌙 Beyond Earth - Starlink is developing very high-bandwidth lasers to connect the Moon, then Mars, building an "interplanetary mesh." - All of that depends on getting safety right in low Earth orbit first. 💡 Key takeaways - Starlink is the world's biggest constellation, and it's moving lower to be safer. - It makes about 1,000 collision-avoidance moves a day, with nearly 100x more caution than the industry standard. - The biggest risk is operators who don't share where their satellites are going. - StarMind could scale to 1 million AI satellites, with launches starting next year. - "Coordination is a key element for realizing all of our ambitions."

what sf taught me about asking for socials at tech events (and what they actually mean) - twitter: great to meet you - linkedin: i hate you - discord: lets hang out irl - instagram: let's pretend we want to hang out irl but just silently watch each other's stories until the end of time - number: im gonna ask you to do me a favour in 1-3 days and then never speak to you again - email: im secretly signing you up to my newsletter as soon as the event ends - snapchat: you look nont*chnical - github: i love you

Tokenized Stocks Are Being Won by Distribution As per @tokenterminal , Tokenized stocks stood at $3.56B in the week of Sep 21, up 65% from $2.16B in the week of Jun 29. That is roughly $1.4B added in 12 weeks, going into Q4. @Ondo Finance leads with 25.9% and $928.7M. xStocks follows at 23.8%, @binance bStocks at 20.6% and Securitize at 12.4%. The top four issuers hold 82.7% of the market Ondo's lead is 2.1% over xStocks and 5.3% over bStocks. That makes it the leader in a three-way race rather than a dominant player. @BNBCHAIN holds 29.5% of the market at $1.1B. Ethereum is at 21.5%, Solana at 20.2% and Avalanche at 11.9%. Arbitrum (5.6%), X Layer (5.0%) and Robinhood Chain (4.1%) make up the next tier, and Base is at 1.0%. Binance bStocks at 20.6% of $3.56B is about $734M. If bStocks sits on BNB Chain, roughly 70% of the chain's value is the exchange's own product. It reflects where an exchange with a large existing user base chose to issue, Ethereum and Solana are split across Ondo, xStocks, Securitize and others, and none of those issuers has a single distribution channel of Binance's size. Robinhood Chain at 4.1% and Robinhood as an issuer at 4.9% follow the same pattern at a smaller scale, with a broker issuing on its own rails. Bunt's POV Ondo's 25.9% is the most exposed number in this dataset. Exchange-native issuers grow with their own user base, and Ondo has to win through partners it does not control. I believe the Q4 test is whether Ondo holds its share while the total keeps expanding. If exchange-native issuance takes the share instead, the chain leaderboard will keep reflecting distribution rather than infrastructure.

⚓️ Ethra Ship Notes｜Vol.050 Today, I came across a number that made me stop. Nearly 1,900 vessels are now considered part of the maritime "dark fleet" according to Windward, roughly tripling since the Russia-Ukraine invasion. The interesting part isn't just the number. It's what the number tells us about visibility. A ship can disappear from AIS. That doesn't mean the ship disappears from the ocean. It just disappears from one information layer. And that's a very different thing. This is where I think Sea Verity's approach gets interesting. Instead of asking a single system to tell us the truth, it combines different sources. Reporters on the ground. AI analysis. Controller nodes. Each piece adds another layer of evidence. And rather than forcing every observation into a simple "true" or "false", the system is designed around confidence scores. I like that approach. Because the physical world rarely gives us perfect information. A satellite image can be obscured. A reporter can only see part of a vessel. AIS can disagree with visual evidence. Weather can make everything harder. The honest answer isn't always certainty. Sometimes it's: We're 90% confident this is what happened, and here's why. That's much more useful than pretending the other 10% doesn't exist. For insurers, traders, logistics companies and regulators, knowing the confidence behind a piece of maritime intelligence could be just as important as the information itself. The ocean is enormous. Maybe the answer isn't one perfect signal. Maybe it's many imperfect signals learning how to verify each other. @EthraShip #EthraShip# #EthraShipProtocol#

the reason i'm so chronically online on X is that i owe my entire career to it. every job i've had has been through relationships i've made here, and as i hit 50k - a number i never thought i'd see on my profile - i can't help but feel a little emotional. you see, i started building up my profile when @wifelette and @tomdale took a chance on me many years ago - a nobody in melbourne who was still learning how to code in js - and invited me to speak at @EmberConf. i had never been to a conference at that point in my life, let alone speak at one. they found me through my tweets sharing my blogposts about learning the framework. i'm not exaggerating when i say that my life changed after doing that talk. public speaking was my greatest fear and i was visibly shaking for the first 5 minutes of my talk, but somehow i managed to remember everything i had practiced. that talk was how i got my first real job (and moved to the US) at @DockYard, thanks to @bcardarella also taking a chance on me. throughout this time i continued posting on twitter and building up my profile little by little. after you've done one talk, the next one is a little easier and so i kept doing more of it - seeing the world i had never been exposed to before. i got my job @netflix the same way, through doing a talk, and people taking a chance on me. some of you may be surprised to know that i never majored in CS and that i'm a self taught programmer. so going through a FAANG interview was inconceivable to me at that point in my life. i actually tried to back out of the interview, but they convinced me to do it anyway, and im glad that i did. i then got my job at facebook through Dan Abramov (i miss him here!!), who i met at a conference talk i did in London. we stayed in touch on twitter for a while before he reached out to me asking if i would be interested in working on the react team (uh, hell yes?! but wait, me??). massive imposter syndrome has followed me everywhere. now at @cursor_ai and @SpaceXAI, i feel so lucky that i get to work alongside such crazy talented, driven, and ambitious people who want to build beautiful products for everyone. and i'm also still in disbelief that this many people care about what i have to say here. thank you everyone for taking a chance on me, and thanks @X for being there for me this whole time 🤍
