Samsung Galaxy S25 Ultra has completely targeted its competitors at the iPhone, and no longer competes with Chinese brand phones. This is because young people in South Korea are almost completely occupied by Apple, and Samsung’s strategy is to pull these young people back, so it strives to make Galaxy look like the Apple iPhone. There are several reasons for not competing with Chinese brands: 1. On the surface, although the Chinese Ultra models have powerful cameras and are suitable for those who pursue the ultimate in images, they are only limited to these people. Overall, the sales of Ultra models are not high, and even the sum of all brands of Ultra models cannot be compared with the sales of S24Ultra. 2. Moreover, these models with powerful cameras are relatively thick and heavy, with serious camera bulges, and the design is not perfect. It cannot be perfect. This design may not be suitable for everyone. Samsung will not easily take the risk to adopt this design in the global market. 3. The infinitely enhanced camera configuration will greatly increase the cost, which is difficult for Samsung to accept, and the production of this frequently updated camera may not be able to support Samsung's sales demand of tens of millions. In short, the Chinese brand Ultra model is more like a special non-popular model suitable for geeks. The Galaxy S25 series is defined as a popular model, and it must consider everyone's feelings and sufficient supply. This is why Samsung will not design the S25 Ultra as a Chinese brand Ultra. It remains consistent with the iPhone 16 Pro Max, but subtly. It is always slightly better than it For example, it is a little thinner (8.2mm vs 8.25mm), a little lighter (219g vs 227g), a little narrower bezel, a little stronger performance, a little more camera (retain 3x), a little more ultra-wide-angle pixels (50MP vs 48MP), a little bigger battery, and a little faster charging. Even the most incredible improvement: One UI 7.1 is a little smoother than iOS18 software. This is happening.

Hello Tata Motors I purchased a Tata Nexon EV (30 kWh battery pack) on 10 February 2024 for around ₹18 Lakhs. Tata claimed a range of 325 KM, but throughout my ownership I NEVER received more than 175 KM on a full charge. Now the condition has become even worse. My battery drains so fast that I can barely drive 90 KM per charge. After reporting this issue, even the service center admitted there is a battery problem. At the time of purchase, Tata Motors clearly promised an 8-year / 160,000 KM battery warranty and assured us that defective batteries would be replaced with NEW ones. But now, when the issue has actually occurred, they are trying to replace my battery with a REFURBISHED (second-hand) battery instead of a new one. I raised this issue in February 2026. It has been months, and despite continuous follow-ups, there is still no battery replacement and no proper response from Tata Motors. What is more shocking is that Tata keeps blaming driving habits for the poor range. But according to THEIR OWN meter, my average consumption over the last 6434 KM is 91 Wh/KM, which technically should deliver around 329 KM range. Yet in reality, I never received anything close to that. To make things worse, the car makes frightening noises while charging. Honestly, it feels unsafe and scary, as if something could go seriously wrong at any moment. And when I asked Tata about exchanging this problematic vehicle, they offered only ₹5 Lakhs for a well-maintained 1.5-year-old car purchased for ₹18 Lakhs. Is this a joke? My demands are simple: 1. Provide a BRAND NEW battery replacement instead of a refurbished battery. 2. Offer a fair replacement/exchange value for the vehicle. This has been the worst ownership experience of my life. Extremely disappointed with Tata Motors and their after-sales service. TATA.ev Nitin Gadkari Department of Transport

Those investing in submarines today may be wasting money. A Virginia-class submarine, powered by an S9G reactor, has a submerged displacement of around 10,000 tons and costs approximately $4–5.8 billion. Its top speed is over 30 knots. Now imagine a much smaller reactor, with power and weight around 15% of the Virginia's, used solely to continuously recharge a solid-state battery bank. Solid-state batteries weigh about half as much as lithium-ion batteries while offering 2-3x more energy capacity. In practice, this means that with the same battery weight, such a sub could achieve roughly 3x the energy gain, In terms of speed, solid-state batteries deliver double or higher discharge rates (potentially 10–20C vs. 5–10C for lithium-ion), ideal for sustained sprints above 30 knots lasting many days and a cruising speed around 25 knots. All this with 15% less overall weight, much quieter operation on batteries alone, and the same endurance as a conventional nuclear sub. And the cost? A micro-reactor would be 15–25% the price of a conventional one, small, modular, low-temperature/low-pressure. This means that when a more modern reactor is needed, you simply swap the module. A micro-reactor paired with solid-state batteries could make a Virginia-class sub $1.2-1.6 billion cheaper, quieter, and leave far more space for weapons, additional batteries, or crew comfort. That's why this system would put all existing submarines at a disadvantage in terms of cost, space, and stealth. Those not adopting micro nuclear reactors can follow what the Germans, Japanese, and French are doing. The Japanese pioneered lithium-ion batteries with diesel chargers, giving their submarines excellent value for money. The Germans chose a fuel cell AIP system to recharge lithium-ion batteries, while the French opted for a similar Japanese-style approach with a battery configuration allowing up to 80 days endurance, making the new Scorpène highly competitive. Starting around 2030, production will shift to solid-state batteries, tripling the capacity of these conventional submarines and enabling silent navigation at around 25 knots for days,making them superior in stealth and speed to many nuclear submarines currently in service. Submarines powered by solid-state batteries, recharged via micro-reactors, fuel cells, or diesel, will be superior: better armed, cheaper, and stealthier than anything we know today.

If last year was great. This year was 🤯. Alhamdullilah. 10 days. 3 houses. 22 Muslims in tech. The houses were packed mashallah with founders including 3x YC founders, exited founders, VCs in the Muslim space, apps with millions of users, founders of Muslim accelerators and engineers working at leading companies. People flew in from 🇬🇧🇦🇪🇨🇦🇺🇸🇧🇭🇳🇱🇮🇪 to make this. SF Tech House | 2024 Edition | The Highlights: ✨ House dinners with Muslims from companies including Microsoft, Tesla, Google, YouTube & Neuralink ✨ Private house fireside chats with special guests including exited founder to Uber, ex-VP at Google Cloud and Sami Hamdi (Sami Hamdi سامي الهاشمي الحامدي) ✨ Muslim Tech Fest (Muslim Tech Fest) - Haroon's talk was literally one of the best I've ever heard. ✨ Discussions around AI & Ethics at Zaytuna College with Hamza Yusuf. ✨ Visits to Stanford (absolutely stunning ... had to get me some merch) & Berkley university campuses ✨ MTW Kick Off Lunch at Sals + Tech Dinner at Zareens ✨ Lunch + tour of Google with their Muslim Network including a Demo Day at their offices. We asked some important & tough questions. ✨ White Water Rafting on South Fork American River. ✨ Q&A at YC with YC Partner Brad Flora who was very nice and accommodating. ✨ & Buildspace tour with Omar Waseem + Q&A with their GP Hubert Thieblot ✨ Visit to Apple Visitor Centre in Cupertino ✨ Experiencing Waymo (driverless taxi) in San Francisco ✨ BBQ with Muslims in Tech in South Bay ✨ Marshmallows on the Beach with the Muslim Bay Area community It was an unbelievable week packed with value and amazing vibes alhamdullilah ❤️ The talent in the house was insane. A text I received from someone staying in the house after returning home: "I can without doubt say that there are a few unicorns coming out of that house. What you’ve done is unprecedented for our community, I always felt we were the underdogs, I can almost certainly say after this that we are now in the lead. I don’t think there is any other community who is so supportive of each other, while being ambitious to try to build great things alhamdulilah." We all left with huge determination to build impactful solutions for humanity, to encourage ihsaan (perfection) and and to bring some of our learnings from the Bay Area to our respective countries to help build Muslim tech ecosystems across the world. I pray this trip helped plant some seeds 🌱 We'll be measuring the success of it by the progress we see in the years to come inshaAllah!

Back when I had nothing… I was a nobody to most people. TBH, my parents didn't even see me getting to where I am today. It's just the truth, the chips were stacked for my sister. Not me. But it's just not the reality today. However, there was ONE person in my life that didn’t see me that way. My significant other saw something in me before a lot of things. Before all my wins. Before the $. Before any proof. And honestly… that means a lot to me, if not the most of all. I’ve always been wired a little different. I’m a mix of finance, engineering, and tech, with a sprinkle of obsession. I learned and studied from the best. Warren Buffett for how to invest. Elon Musk for work ethic and where the future is going. And once I saw it… I went all in. Bc when you truly understand what you own… you don’t need 20 bets. What you really need is conviction and just a few bets. That’s how I approached everything in my life. All the way from Apple… to Tesla… to 𝕏… to xAI… and now SpaceX. I believe I have an eye for spotting the best entrepreneurs and companies early, before it becomes obvious to everyone. And when I see it, I back it 100%. That’s just who I am. I don’t need a big circle. I’ve already got my day ones. I don’t need approval. I grew up my whole life with doubt and hate, so what’s one more? At this point, the levels are just too different. And yeah… it's true, it actually gets harder to make new friends when you’re moving like this. So I stay loyal to the ones who were there when I had nothing. I made it with Apple - youngest in, youngest out. Then I made it with Tesla… while people were laughing, doubting, calling me crazy, telling me I was going to go bankrupt with Elon. Fast forward to today, now I'm heading into something even bigger. If the story plays out the way it’s shaping up… SpaceX could have the largest IPO in history this year. The company is talking about raising over $75B… at a $1.75-$2 trillion valuation. For context… the biggest IPO ever - Saudi Aramco - raised about $29B. This would be more than double that. Let that sink in deep. To me this is more than just an investment. This is owning a piece of the future of space, energy, AI... extending the light of consciousness forward in case something happens to Earth. People can call me crazy. People can call me cocky. Arrogant. But the people that actually know me know the truth - I’m just real AF. I say what I believe, and I stand on it. And I genuinely don’t care what people think. I have two middle fingers always held high for those kind of people. That’s probably why I’ve been able to win the way I have. My significant other tells me to slow down sometimes. And I get it. But for me… What’s the point of life if you play it safe? If you see an opportunity that can change everything… and you just sit back? That’s not me. I’d rather go all in on something I believe in… live with intensity… take the hits… and actually feel alive and live life with fulfillment. Laugh if you want, doubt if you want. Some play it safe, a few go all in. You can call it risky. You can call it stupid. You can call it crazy. I call it living. Bc at the end of the day, I'd rather go all in on something I believe in and fail... than spend my life wondering "what if."

before pumpfun livestream feature is updated, before my account goes big and before I got some money, before everything, there was this token the beginning was so small at that time(over 2 years ago) rug was still rampant and I thought like 'why wouldn't they grow their project bigger rather than rugging at 10k?' sadly I became one of them now but regareless of it, I launched it just for 100% fun with buying 1 sol and turned on camera at TG group just for fun too someone said, "yo bro you should keep doing this this gonna be hella huge" so I did it I still remember the 2 guys who carried the whole project with max shilling and leading community members: Noble(this guy was pretty mean to me lol but still he was a goat) and Cassius(actual goat) it was a pure joy I did a stream 24/7 even while I was sleeping at TG and people were having fun in here(one girl took off her shirt when I was sleeping and I fucking missed it 💀) and my big bro Tyrelle Anderson-Brown came into my coin and helped me with 2 sol. I still remember this thankful money. with this I ate a nice dinner with my gf I still don't know the reason(maybe money laundaring?) but it went 5M and at this day when I woke up and checked my trojan, THIS WAS THE FIRST TIME I HIT 6 FIGS IN MY LIFE and I didn't sell a penny because community was more important than money at that time here's a list what community did for me - bought me a new iPhone - bought me a new MacBook(these two were for a better stream - my PC and phone was trash) - funded me almost every equipment for stream - formed a team with 10-11 members and kept supporting me they even put my sleeping video at Timesquare, NY here's a video so how can I sell this lmao but sadly the coin goes up, the coin goes down too and this happened to my coin too it was sooo tough days but I kept doing my best and it ended from up 130k to making 3k only this project was like if someone asks me "what did you do in this year? can you answer to this question with confidence?", I will answer this coin with 100% sure and I just turned on livestream with this coin just for fun too was very good days

The haters told me I’d never own a Tesla Model X. Then I bought one. They told me I’d never own a Cyberbeast. Then I got one… and put tens of thousands of miles on it. They told me leaving Apple was crazy… that walking away from a great career to bet on myself was a mistake. Then I became financially free, built my own business, started making more $ doing what I love, and got my time back. They told me posting about Tesla and Elon every day was a waste of time and wasn’t exciting. Then that little account turned into Teslaconomics… it opened doors I never expected. I went from watching Tesla launches online to getting invited into the room. From talking about Robotaxis to actually riding them. From dreaming about the future to sitting inside a Cybercab with no steering wheel and no pedals while it drove me around Austin. And through all of it, there has always been somebody saying: “You’ll never do that.” “You’ll never get that.” “That’s not going to happen.” I’ve learned something over the years… Often times the best thing you can do is stop arguing with people and just keep building your life. Don’t waste your time and energy on them. Let the results answer for you. Now I can’t wait to see their faces when the next-gen Tesla Roadster is sitting in my garage. SpaceX package if Tesla lets me. Some people see something they’ll never have in life. I see the next thing I’m actually going to own. See you when it gets here. And I’ll be smiling at all of them again, saying I told you so, again.

📣 Puffer UniFi V2 testnet is now live! 🐡 The UniFi V2 testnet is officially live, and we’re inviting builders to explore the stack and join the next phase of Ethereum-native infrastructure. With the advancement of based rollup technology, UniFi offers a practical path forward to address Ethereum’s fragmentation and foster ecosystem growth. UniFi-OP enables Ethereum builders and users to avoid choosing a “winning” L2 or giving up revenue. Based sequencing keeps rollups, appchains, and general-purpose chains fully composable with Ethereum. Thanks to UniFi AVS, rollup owners can now share priority fees and MEV with validators. This upgrade was made possible in collaboration with Gattaca, , Automata Network, and Ethereum. ⚒️ What Builders Get • Governance‑optional rollups 🗳️ • Custom fee markets (subsidize, burn, or share) • KYC‑gated or fully permissionless chains 💆 What Users Feel • Sub‑10 ms confirmations ⚡ • One‑click exits to L1 (no 7‑day wait) • Seamless L1 interaction—AMMs, CLOBs, RWAs “just work” 📈 Economic Win‑Win Based sequencing ≠ giving up MEV and Priority fees. Rollup owners, gateways, and L1 proposers share MEV & congestion fees through @puffer_unifiAVS. Alignment without sacrifices. 🧩Pragmatic Composability How composable is UniFi V2? • L2 → L1 withdrawal supported • EIP‑7702 smart‑wallet standard baked in • Atomic withdrawals in the same block (no more 7 day wait) 🛡️Trust‑Minimized, Real‑Time Proving Real time proving is a must have to achieve composability and security that a rollup needs. We came up with a trust minimized pragmatic approach with TEEs for the first phase. In collaboration with Automata Network we now have: • Multi‑TEE provers (Intel TDX + AMD SEV) attest each block in less than 1s. • Hardware diversity = reduced trust assumptions. 🏎️UniFi AVS (Gateway Registry) For Preconfimrations (preconfs), we take advantage of delegated proposing to gateways to bring the speed. This service requires shared security. 🏗️Built on : • Validators opt in and delegate proposer rights. • They earn extra yield for serving preconfs. • Restaking validators solve the cold‑start problem. 💻 Preconf Phases • Centralized gateways at launch. • Progressive onboarding → many independent gateways for decentralization. • Proposer‑delegated based sequencing (speed). 🗺️Roadmap • ✅ Hybrid Based‑OP stack with TEE proving & fast gateways • 🔜 ZK proving • 🔜 Universal Registry Contract (URC) by ****@fabric_ethereum for slashing • 🔜 Commit boost Commit-Boost 📻 🕶️ 🦇🔊 integration • 🔜 Native L1 ↔ L2 ↔ L2 calls All upgrades are backward‑compatible and shipped incrementally. ⚔️Security Model at a Glance • Restaked ETH → slashable backing • Multi‑vendor TEEs → hardware redundancy • ZK fallback → cryptographic safety net No single point of failure. 🎯Metrics That Matter The KPI moves from TVL to transaction volume & speed. High‑frequency order‑flow is real revenue—and UniFi lets dApps capture it instead of donating it to someone else’s sequencer. 🧑‍💻Code & Collaboration UniFi V2 extends the open work by Gattaca on Gattaca‑OP. Dive into the repos and contribute. 📚TL;DR • Pragmatic composability with atomic withdrawals from the L2. • Trust‑minimized, real‑time proving • UniFi AVS bootstrapped by EigenLayer • Based rollups that share income 🪖Builders: stop choosing between UX, composability, and revenue.

The OriginTrail DKG V10 begins its mainnet rollout with a Frontier-AI Resilience Gate. Today, the final V10 release candidate (the exact contract bytecode intended for mainnet) goes live as a public pre-mainnet, funded with 300,000 ethereum:0xaa7a9ca87d3694b5755f213b5d04094b8d0f0a6f tokens: a 200,000 TRAC honeypot pool of real, drainable positions plus a 100,000 severity-reward pool. Independent researchers and AI-augmented teams are invited to break it: drain the honeypot and you keep what you take, and every valid finding is paid by severity. It’s a real pass/fail checkpoint: findings are fixed and verified first, and clearing the gate is the precondition for the mainnet launch. The first step of the DKG V10 deployment, by design. Why lead with security instead of shipping and patching later? On May 29, 2026, a researcher using Claude Opus 4.8 surfaced a critical, roughly four-year-old soundness flaw in Zcash 🛡️’s Orchard pool (a bug that had passed repeated expert review) in about a day, with a working proof-of-concept. The moment matters; the trajectory matters more. Claude Mythos, Anthropic’s frontier model, is so capable at finding vulnerabilities that it was first withheld from public release and run only inside a defensive partner program, where it reportedly surfaced more than ten thousand high- and critical-severity bugs in its first month. It’s now days from a reported public release. The bar for what an attacker, human or AI, can find only rises from here. As Anthropic framed it, the advantage goes to whoever uses these tools first: attackers in the short term, defenders who fix bugs before code ships in the long term. The Resilience Gate is how we make sure we’re on the defenders’ side, testing DKG V10 not just against today’s models but against what arrives next. For anyone shipping on-chain systems, the implication is simple: this code launches once, mistakes can’t be undone, and the responsible move is to invite that scrutiny before any user value is at stake. The path to mainnet, in four phases: Phase 0: Freeze. Final contracts locked and deployed (complete) Phase 1: Frontier-AI Resilience Gate. Open review program, through June 17 Phase 2: Mainnet launch. Hardened, feature-complete V10 (week of June 15) Phase 3: Continuous audit. Every contract, ongoing after launch If you work in smart-contract security, or build with AI that does, we’d welcome your review. No allowlist, real rewards, coordinated disclosure. *Dates are indicative: the exact mainnet date depends on the pace of network bootstrapping and the time needed to patch and re-verify any more severe findings from the Gate. Release candidate 17 (rc17): Bug bounty program and honeypot details:

Vector Database by Hand ✍️ Vector databases are revolutionizing how we search and analyze complex data. They have become the backbone of Retrieval Augmented Generation (#RAG). How do vector databases work? [1] Given ↳ A dataset of three sentences, each has 3 words (or tokens) ↳ In practice, a dataset may contain millions or billions of sentences. The max number of tokens may be tens of thousands (e.g., 32,768 mistral-7b). Process "how are you" [2] 🟨 Word Embeddings ↳ For each word, look up corresponding word embedding vector from a table of 22 vectors, where 22 is the vocabulary size. ↳ In practice, the vocabulary size can be tens of thousands. The word embedding dimensions are in the thousands (e.g., 1024, 4096) [3] 🟩 Encoding ↳ Feed the sequence of word embeddings to an encoder to obtain a sequence of feature vectors, one per word. ↳ Here, the encoder is a simple one layer perceptron (linear layer + ReLU) ↳ In practice, the encoder is a transformer or one of its many variants. [4] 🟩 Mean Pooling ↳ Merge the sequence of feature vectors into a single vector using "mean pooling" which is to average across the columns. ↳ The result is a single vector. We often call it "text embeddings" or "sentence embeddings." ↳ Other pooling techniques are possible, such as CLS. But mean pooling is the most common. [5] 🟦 Indexing ↳ Reduce the dimensions of the text embedding vector by a projection matrix. The reduction rate is 50% (4->2). ↳ In practice, the values in this projection matrix is much more random. ↳ The purpose is similar to that of hashing, which is to obtain a short representation to allow faster comparison and retrieval. ↳ The resulting dimension-reduced index vector is saved in the vector storage. [6] Process "who are you" ↳ Repeat [2]-[5] [7] Process "who am I" ↳ Repeat [2]-[5] Now we have indexed our dataset in the vector database. [8] 🟥 Query: "am I you" ↳ Repeat [2]-[5] ↳ The result is a 2-d query vector. [9] 🟥 Dot Products ↳ Take dot product between the query vector and database vectors. They are all 2-d. ↳ The purpose is to use dot product to estimate similarity. ↳ By transposing the query vector, this step becomes a matrix multiplication. [10] 🟥 Nearest Neighbor ↳ Find the largest dot product by linear scan. ↳ The sentence with the highest dot product is "who am I" ↳ In practice, because scanning billions of vectors is slow, we use an Approximate Nearest Neighbor (ANN) algorithm like the Hierarchical Navigable Small Worlds (HNSW).

As college football coaches, due to our new annual college football schedule, there aren’t consecutive “Days Off” like we used to have in the past, thus the reason I’m taking advantage of these next few days off — starting today. Context: this is the first time the Atuaia family has been together as one unit since 2020 Covid Christmas. We got up this morning (11am😂) to ready ourselves for a FAMILY PHOTOSHOOT that hasn’t happened since 2017 due to 3 LDS missions, 3 job changes, 3 moves to 3 different states, and mostly the multiple excuses I’ve given NOT to be available for this event. After the Photoshoot, our kids wanted to go to Savage Fish in Millcreek for Pokē. My kids know a little about it, but we (Liz and I) have a Christmas story concerning the owners of Savage Fish. 16 years to the day, we were at BYU struggling financially as I was a full time graduate student and Liz a stay-at-home Mom with our 6 young kids to look after. Literally, every penny went to pay for our daily survival. On this day (23rd) these angels on earth came to our 2 bed/1 bath Wymount Terrace apartment to save Christmas for 6 little kids and 2 thankful parents. Today, as I watched each of my kids order their pokē bowl, the same who were blessed by the owners of Savage Fish years ago, I tugged at Liz’s sweater to reminder her of that day. She smiled and simply said “Tender mercies.” Right now, I’m typing this and drinking my kava while listening to all 7 of my kids, led by the oldest child in our family, putting together over a hundred “GIFT PACKAGES” to personally handout to less fortunate folks outside homeless shelters, multiple public parks, and other areas frequented by this demographic in Salt Lake City area. My kids, not prompted by me in anyway, have done this everywhere we’ve lived in the past: Charlottesville Virginia, Pullman Washington, and now Salt Lake City, Utah. We have been the beneficiaries of other people’s kindness all our lives (including recently with a stranger saving my wife’s life—a stranger we have not found yet), paying it forward is simply just the right thing to do. If we have any juice left tonight, we’ll likely do our annual Christmas Song for the online masses. Or, we’ll just mixx as a family and enjoy laughing like crazy. Either way, it’s been an awesome day.
