🌟 "SHOULD I BUY AN IPHONE FOR TRACKING?" 🌟... tl;dr at bottom I've been using a facecam and Nvidia tracking for a long time and upgrading to a used iphone 13 combined with vbridger, the difference is HUGE. Here is my take on it! Why is Facecam > iPhone? ✅️ More affordable, esp for those using android phones ✅️ More convenient. If you launch Vtubestudio, there's a setting where your webcam automatically turns on, which is great. ✅️ Can track pretty well in the dark IF you already have a good webcam for night tracking. ❌️❌️ Stiff tracking at times ❌️ Not good at tracking specific mouth movement Why iPhone > Facecam? ✅️✅️ You can make the most of your model, since movement along the X and Y axes are a lot more accurate and wider. Also tracks eyes and overall face better. ✅️ More EXPRESSIONS. If your rigging allows for it, things like cheek puff, and tongue are able to be tracked. As far as I know, I cannot do this on facecam. ❌️❌️ WAY more expensive or requires that you have an iPhone already. Needs more set-up (need phone stand right in front of you, need to hook your phone up to a charger at all times, phone could possibly overheat as well if it's old, so you might need a cooler). TL;DR For me, if you have an extra 200 to spare for WAY better tracking, I would 1000% recommend buying a used iPhone on Amazon. iPhone X is the BARE minumum, I would recommend 12/13 so that your phone does not overheat. I do not need to use a cooler for my used iPhone 13. Being able to use my rigging to its fullest makes the model feel so so so different (in a good way). Feel free to reply with any questions, I will try to answer them!show more

🚨 SCIENTISTS JUST SHOWED THAT LIGHT CAN TWIST MATTER... USING ITS MAGNETIC FIELD. For a long time, physicists assumed the magnetic component of light was far too weak to have any meaningful effect on matter compared to its electric field. New experiments are challenging that view. Researchers have demonstrated that intense, properly structured light can induce magnetization and even mechanical twisting in materials through its magnetic field alone. This is an extension of the inverse Faraday effect, but observed with greater strength and control than many expected. Why this matters: • It opens new ways to control magnetism and material properties using only light • Could lead to faster, more energy-efficient magnetic memory and spintronic devices • Offers a new tool for manipulating matter at the nanoscale without physical contact • Bridges optics and magnetism in ways that were previously difficult to achieve The deeper implication: Light is not just an information carrier under the right conditions, its magnetic field can directly reshape the magnetic and mechanical state of matter. This blurs the line between electromagnetic waves and material control. If these effects can be scaled and made practical, we may eventually use light itself as a precise tool to write magnetic information or mechanically actuate tiny structures, rather than relying solely on electric currents or physical forces. We’re discovering that light still has hidden capabilities we haven’t fully exploited. How do you think being able to control matter with light’s magnetic field could change technology in the next decade?

My question was are you strict Keto? … A... Keto diet is not for everyone much like a carnivorous diet is not for everyone. We all have a different microbiome that allows us to eat what we eat. Not all humans are created equal. Much like a lion cannot be vegan and an elephant cannot be carnivorous. Their microbiome dictates their diet. Yes, I tested the animals below….My recommendation is to Stop ALL gluten…you probably killed the microbes allowing you to absorb gluten or simply iron .. It is easier and cheaper to just stop gluten than look into those lost microbes as it is a research protocol needing funds. Other options are eating more apricots, Brussels sprouts, swiss chard, etc … You can test your microbiome with ProgenaBiome to see what microbes are missing and compare to our research database and start on a research protocol but it ain't cheap as genetic sequencing of the gut is expensive at the level we do it and it is precision medicine research, not your usual clinical trial. Lastly, putting on my GI hat, I would advise for an Egd/colo by any GI to rule out anything in the bowels. Make sure they do a duodenal biopsy. All my best. You can always pm me.show more

Some news: after four wonderful years at UC Berkeley... Haas, I'm heading to Columbia Business School this fall as an assistant professor in the Decision, Risk, and Operations Division. I'm incredibly excited to be joining a division full of brilliant colleagues studying marketplace design, online platforms, business analytics, and data-driven decision-making -- topics that perfectly complement my own research. And I can't wait to re-embrace NYC life – pizza at all hours of the day, grimy music venues in Bushwick, and a robust public transit system! At the same time, I'm also sad to be leaving Berkeley. Haas has been the perfect place to launch my academic career. The brilliant colleagues, engaged students, and collaborative atmosphere here have helped me grow as both a researcher and teacher over the past four years. I'll also deeply miss the Bay Area's amazing nature and weather, as well as its unique blend of innovation and idealism. When I joined Haas, I announced it with a cameo from Chris Diamantopoulos (AKA Silicon Valley's Russ Hanneman). I considered doing the same now—maybe getting Eric Adams, Jalen Brunson or James Murphy for a proper NYC welcome—but the timing feels off. As excited as I am about my new job, this career move comes at a complex time when universities across the US, including Columbia, are navigating challenging tensions between government pressures and academic independence. I believe in the importance of maintaining both institutional autonomy and protecting all members of our academic communities. Despite the challenges at hand, I remain hopeful about Columbia's future and its enduring mission. As Columbia's motto reminds us, "in lumine tuo videbimus lumen" — "In your light we shall see light" — suggesting that through education and collective wisdom, we find illumination and a path forward. I'm excited to join this historic institution during a pivotal moment and to contribute to Columbia's long tradition of creating positive change through knowledge and research. See you in New York! 🗽show more

I hope this post gets more than my average... 60 views bc it’s important. Please repost if so inclined: In the clip below from today’s Dan Bongino montage of Comey, the corrupt former FBI Director who caused chaos with the Russia Collusion Hoax, he unilaterally cleared HRC for mishandling classified materials and destroying evidence before the 2016 election. During this Press Conference I was at the FBI office with my agents working on a cartel prosecution. We all stopped to watch with amazement as Comey was initially eviscerating HRC’s unlawful conduct, but as we all now know he eventually stated “no reasonable prosecutor would bring such a case!” I remember turning towards my agents and saying “well, I guess I’m an unreasonable Prosecutor . . .” I knew in that moment at my deepest core, based on years of prosecutorial experience and instinct in federal law enforcement, that the reason Comey cleared HRC had nothing to do with the prosecutability of that fact pattern - it was political interference in its most corrupt form. And here’s why. Comey had NO authority to decline prosecution. At the end of the day, he was “just a cop” so to speak. His ONLY authority was to turn the investigation over to the DOJ which has sole discretion on who to prosecute, or not. He can make a recommendation, but not a decision to not prosecute, especially based on the reason stated. That’s why this will go down as one of the most embarrassing and demoralizing moments in FBI history. My agents were crushed. They knew what just happened as much as I did. This man stepped out of his lane to cover and protect a politician, while at the same time, without any of us knowing in that moment, he was also beginning the years long political assasination of Trump in what later became the Russia Hoax.show more

Today marks General Availability of AgentCore, a set of... infrastructure building blocks for developers and companies to build secure, scalable agents. When we first started AWS, the vast majority of developers were spending most of their time on the undifferentiated heavy lifting of infrastructure instead of what differentiated their feature. So, we solved that problem by building primitive building blocks like compute and storage and database that would allow teammates and customers to quickly build and deploy new experiences without having to reinvent the wheel each time. We realized the same thing was happening with AI agents. It's too difficult and it's slowing customers down. That's why we created AgentCore, a set of services to build, deploy, and operate highly capable agents using any framework or model, with enterprise-grade security and scalability. These building blocks (like serverless secure runtime, memory, observability, a gateway that does MCP translation, etc) help customers tackle some of the biggest challenges of going from prototype to production, much more quickly, securely, and scalably. AgentCore has been in preview for several weeks, and customers have been quite excited about it. The AgentCore SDK has already been downloaded over a million times and we're seeing transformative results, such as Cohere Health expecting to reduce medical review times by 30-40% in highly regulated healthcare, and teams at Cox Automotive and Experian are embracing its flexibility to deploy and operate agents at scale. Inside Amazon, our Amazon Devices Operations & Supply Chain team is using AgentCore to develop an agentic manufacturing approach where AI agents work together to automate manual processes – turning what used to be days of engineering time into processes that take under an hour with high precision. Just like AWS changed how companies build and scale applications, we believe AgentCore will do the same for AI agents, enabling the next generation of innovation.show more

I’m incredibly excited (and very nervous!) about the launch... of AMPLIFY. I have always felt enormous gratitude to have been born in Australia but, like many of you, I felt that we weren’t going in the right direction as a country. I started turning my mind to what we might do about the situation and got advice and encouragement from some amazing people. We decided to set up an organisation that is all about community at its core. So what is AMPLIFY? AMPLIFY is a community where Australians get to have their say and make a difference on the most important issues that we face as a country. We are non-partisan and completely independent of any political party. Anyone can become a member of AMPLIFY at no charge. We are seeking to find “uncommon ground” and identify the right solutions to the big issues facing Australia. We will do this by bringing our community together for events in all parts of the country, we will facilitate online conversations, share evidence, talk with experts and come up with solutions. The way in which we will make an impact is by taking our ideas to politicians and Amplifying the voice of our community to spark change. Our goal is to help Australia become a more prosperous, fairer, more cohesive and happier country. I will be serving as founder and Chair of AMPLIFY. My job at Square Peg is not changing in any way. Georgina Harrisson is our CEO and has been doing a remarkable job since joining last October. I am also really proud that my son Joel is an important part of the AMPLIFY team. I am grateful to the amazing group of people who have joined the board; Suzi Carp, Rona-Glynn-McDonald, Kate Jones, Gill McLachlan, Dom Perrottet, Kate Pounder, Mike Schneider and Zara Seidler. If we are going to be successful we need your support. You can sign up at our website and become a member in a few seconds. Please spread the word. Please share this Tweet or, better still, post your own Tweet and share with your audience.show more

BREAKING: Anthropic just dropped Opus 4.8—and it is a... MONSTER We've been testing for about a week Every 🪨 and our verdict is they could've just called it Opus 5, it's that good. Here's our vibe check: - Beats GPT-5.5 on Senior Engineer bench. On our toughest benchmark Opus 4.8 scores a 63—a hair higher than GPT-5.5's score of 62, and a full 30 points higher than Opus 4.7. It tackled a ground-up rewrite of a production codebase, and actually built something that works. HOWEVER: Coding performance varied a lot at different reasoning levels. We recommend using it on xhigh for best results. - Incredibly good writer. Opus 4.8 scored a 79.6 on our writing benchmark—measuring models on real-world writing tasks we do all of the time like essay writing, promo email writing, and more. It beats GPT-5.5 by 6 points. It produces well-written prose with fewer "AI-isms". It's also very good at writing in your voice given the right context. HOWEVER: Writing performance also varied with reasoning levels. Medium reasoning had higher incidence of AI-isms—we found best results with high. - Beast at knowledge work. Opus 4.8 is very good at general knowledge work tasks like report creation, research and more. It produced the best PowerPoint one-shot we've ever seen on our deck generation benchmark. - Emotionally intelligent, willing to question the frame. I've also found it to be quite good at talking through psychological or interpersonal issues. It has a high EQ, and it's also good at not glazing and helping to expand your perspective. Its thought process feels extremely rich and dynamic. THE BAD: These days a model is only as good as its harness, and Codex is still a far superior harness to the Claude Desktop app. This has kept me using Codex + GPT-5.5 as my daily driver, but I am flipping back and forth a lot more between Codex and Claude.

I mentioned $BOT on the Iced Coffee Hour podcast as one of the few ways to play the robotics thesis and still stand by every word in my original thesis: Also tons of good things have happened over the last month: - Lead Standard Bots (US-made robot arms) Series C (now largest holding in $BOT) - Added Prometheus (Jeff Bezos is co-CEO) - Figure shipped their 1000th humanoid robot - NAV is now $249M or $10.51 / share (premium is currently ~2.5X NAV). - Andrew Kang Andrew Kang personally invested $10M more @ 36.71 This current macro is insanely volatile and narratives change fast but this feels like a story-changer and IMO worth a swing. --- *As a reminder: this is my challenge account where I restarted with $35k to go all-in swing trading 1 stock at a time to $10M again. Important disclosure: I currently own 1,514.472674 shares of BOT and wrote this after establishing the position. I may buy or sell at any time without updating this post.

Time, as the Rolling Stones said, is on my... side. The Iranian side, that is. Iran is on land, commanding the Strait of Hormuz. The 'United States' is out at sea, and all of its base belong to us. Iran can break the imperial economy with its weapon of Mass Economic Destruction (MED), but the White Empire can't break them because they're used to it. The ships that didn't leave a month ago are not arriving just now and Iran just has to wait for the imperial economy to blow. Any minute now. Iran is not in a hurry to make (or break) this ceasefire. Their shots have already been fired and they just need to wait a little bit for 'America' to realize it. They can delay this day a bit using the futures market, but eventually the future becomes the present, and then what? All 'America' can do, in its furore, is close the strait even more, which just makes the straitjacket even tighter. 'America' has to move mountains to change their fate, but all Iran has to do is not move.show more

OPINION: ELON AND THE DAWN OF THE WARP AGE... While the rest of the world is busy arguing about the present, Elon has been playing a multi-century game of chess. Most people remember his 2013 conference talk for the Hyperloop reveal, but the real bombshell was his take on the Alcubierre Drive. Proposed by theoretical physicist Miguel Alcubierre in 1994, the Alcubierre Drive is a speculative metric that allows a spacecraft to achieve apparent faster-than-light travel. Instead of a ship accelerating through space, which is limited by (the speed of light), the drive manipulates space itself. It works by contracting the fabric of space in front of the vessel and expanding it behind. Essentially, the ship sits in a "bubble" of flat spacetime, effectively "surfing" on a wave of warped reality. Elon did not just call warp drive science fiction; he broke down the physics of warping space so that space itself does the traveling. When you have a mind that views the speed of light not as a ceiling but as a technical challenge to be engineered around, the future starts looking a lot more like Star Trek and a lot less like a stagnant rock in the vacuum. Elon was a decade ahead of the curve. Back then, he noted that while SpaceX was focused on the immediate Mars roadmap, breakthroughs in warp theory were already bubbling at places like NASA. Fast forward to late 2025, and the vision is becoming reality. Former NASA Administrator Charles Bolden once admitted the goal was warp speed, and groundbreaking research even suggested we are finally moving toward manipulating spacetime without needing the impossible amounts of exotic matter we once feared.

over the weekend, i built an app that i... sincerely hope you will never have a need for, but if you do happen to need a friendly, free, private mri viewer designed to make it easy for you to track tumor progression, you can try it here: here's the story: as some of you may know, last last september, my six year old daughter mira was diagnosed with an extremely rare brain tumor called an adamatinomatous craniopharyngioma, and since then our family has been doing everything we can possibly do to find a cure for her. we tortured chatgpt deep research, put together our own private research team, raised $1.4M and donated it all to Hankinson-Mitra Lab research thanks to $MIRA, explored every remotely applicable drug whether on the market or not, and even began working with md anderson to develop a personalized vaccine that we hope can lead to a more permanent cure unfortunately, we received the devastating news last march that the tumor has continued to grow since her initial surgery, and we had to start to consider more drastic options which would have seriously impacted mira’s quality of life. thankfully, with the help of dr. sabine mueller UCSF Benioff SF and the Hankinson-Mitra Lab at the university of colorado, in april, we started her on an alternative but extremely experimental treatment for this disease. to our unimaginable relief, her tumor has responded extraordinarily well to this treatment which combines tocilizumab (an arthritis drug that blocks IL6 receptors) with avastin (a colon cancer drug that inhibhits VEGF proteins). we know this, because mira gets an MRI scan of her brain every few months. and every time we get a new scan, the first thing we do is compare it against her last scan. so we have to find the matching weight of the scan, and then find the same plane, and then carefully find the slices of the scan where the tumor is visible, and then find the closest match to last month’s scan, then adjust the zoom, rotation, and brightness / contrast so they all look the same. we got pretty good at this. but it shouldn't be this hard. so i built last weekend using gemini 3 with some gpt 5.2 xhigh. you just import your DICOM MRI files (either zip, files or a folder), and you can align all of your scans across multiple dates instantly, just click and drag a rectangle around the tumor on any image, and it will use some very clever algorithms to automatically align up and find the closest matching slice from all your other scans, match the brightness / contrast, rotation, pan, zoom, and even shear to make sure the registration is as close as possible, and make it as easy to possible to compare tumor progression. it has a grid view so you can see all your scans for the same location all at once, and an overlay view so you can quickly compare two scans visually (by holding down the space bar to toggle quickly between two scans), along with tools to animate your scans both within the same sequence as well as over multiple scans to show progression. there is no server, it runs entirely locally on your browser - nothing ever gets uploaded and it's all open source: if you've found this useful, please consider a donation to the UCSF Benioff SF hospital foundation, who has given us extraordinary care over the past year or so:show more

Stephan “Sven” Goslinski is a Toronto District School Board...

Stephan Goslinski is registered with the Ontario College of Teachers OCT_OEEO under registration #713030. A post from dahlia kurtz ✡︎ דליה קורץ caught our eye recently & we decided to investigate further. We found that during Stephan Goslinski’s spare time, he enjoys carrying a giant cross with a keffiyeh tied around it to protests that call for the mass murder of Israelis & glorify designated terrorist groups. Stephan Goslinski was spotted carrying this cross recently at the Ottawa National March on Saturday April 12th. In addition to this, Stephan Goslinski has been spotted at his job as a teacher wearing a keffiyeh. Stephan Goslinksi also runs the sketch drawing account “svencomicsart” & operates the website which carries the sub-brand “Imago Palestina”, a collection of drawings of various figures in the Palestine space. One particular drawing that caught our attention was that of Refaat Alareer, who famously mocked the murder of Jewish babies who were burnt alive on October 7th, asked if they were burned “with or without baking powder.” Is this the type of person you want to be teaching your students without supervision, not knowing what sort of ideologies they may be indoctrinating your child with?

🚨 SCIENTISTS JUST DISCOVERED THAT BACTERIA HAVE BEEN USING... A QUANTUM ENERGY TRICK FOR BILLIONS OF YEARS. In a breakthrough published in Nature Chemistry, researchers from the University of Sheffield (working with IBM and international collaborators) have shown that purple photosynthetic bacteria (Rhodobacter sphaeroides) use singlet fission (SF) as a functional mechanism to enhance light harvesting. When carotenoids absorb blue-green light (via their S₂ state), the energy rapidly undergoes heterofission: the singlet exciton splits into a pair of triplet excitons shared between a carotenoid and its neighboring bacteriochlorophyll (BChl) a molecule. These triplet pairs are long-lived and weakly coupled. They then recombine via triplet-triplet annihilation (TTA), efficiently populating the BChl a Qy singlet state which then transfers energy to the reaction center. This SF-mediated pathway contributes up to ~18% of total carotenoid-to-BChl energy transfer in some complexes and introduces a temporal “buffering” effect, staggering energy arrival at the reaction center. Why this matters: • It is the clearest demonstration yet that singlet fission plays a genuine, functional role in natural photosynthesis • The heterofission mechanism (triplets on adjacent Crt and BChl molecules) explains how bacteria achieve ultrafast SF while maintaining long-lived, harvestable triplet pairs • This pathway helps organisms make better use of blue-green light and may protect the reaction center during fluctuating light conditions The deeper implication: Nature has evolved a sophisticated way to temporarily store and then cooperatively release electronic energy using spin-protected triplet states. This biological strategy offers new inspiration for designing artificial light-harvesting and energy-conversion systems that can buffer and regulate energy flow something synthetic SF materials have struggled to achieve. We are learning that evolution solved some of the hardest problems in photophysics long before we started trying. How might understanding biological singlet fission change the way we design future solar energy or quantum-inspired technologies?

Are you safer with LIDAR, or are you safer... with vision? This is a false dichotomy. The more pertinent question today is "do you have something, or do you have nothing?" As you can see from the clips below, vision based systems avoid countless potential collisions every day. The difference between a crash and no crash isn't what sensor suite you chose — it's whether you have any AI on your car at all. Even if we concede that LIDAR may help prevent some additional crashes, we are really debating whether it is 1% of crashes or 0.00001% of crashes. Not all crashes are super complex and require lasers to detect. Most are simple, routine, and can easily be prevented by today's vision based AI. In fact, evidence is mounting that computer vision based systems can actually outperform more traditional approaches to self-driving. Why? Because the low cost of cameras enables you to create a much larger, more varied, and more diverse dataset. If you want to have expensive custom cars that's fine, but you're going to get fewer vehicles for the same budget. Seeing what's in front of you now is actually less important than predicting what's going to happen next — and the large scale datasets used to train pure vision systems are the best for predicting what's next. Counter-intuitively, the simpler and lower cost sensor actually has properties that make it better suited for training advanced AI. Computer vision based self-driving is often framed by LIDAR proponents as "cheaping out" on the sensor suite to save money. But it's not about being cheap, it's about bringing the technology to everyone. 1.2 million people die on the road every year around the world. That's around 39 million people who've died on the roads around the world since I was born — equivalent to a city the size of Tokyo or New Delhi getting wiped off the map. The status quo is simply unacceptable, and something has to be done to fix it as soon as possible. Of the 1.2 million people that will die on the roads this year, about 40,000 will be Americans. That's about 3%. So if we moved entirely to self-driving cars in America and brought crashes down to 0, 97% of the world's crash fatalities would still be taking place as usual. Deploying a $200,000+ retrofitted self-driving car may work in a few American cities, but it is not going to make sense in most places around the world where fares are much cheaper. Most often, the choice is not between LIDAR and vision. It's between vision or nothing. The best system is the system that's there running on my car when I need it to save my life. To say that all self-driving cars must have LIDAR is to sentence most of the world to death. We can't write off computer vision if we want to make a serious dent in this problem. It's going to be a key piece of the solution. Let LIDAR based players build the best self-driving car they can, and let vision based players do the same. We need to be trying everythingshow more

I came to Linea.eth as a crypto newbie, afraid... to even make a couple of transactions. The testnet toughened me up and taught me a lot. Linea Voyage gave me more confidence and knowledge - I was farming LXP and learning, but mostly in a mechanical way. 👨‍🔬 Everything changed one day when my friend sent me a tweet from Linea announcing that a Frog NFT collection would launch on the network. Without hesitation, I joined the Ethereum Frogs 🐸 Telegram chat and started grinding for WL. Right away, I met Pran, Sᕼᗩᘻᗩ, 0xSupertramp🥕, and the OGs, who are still in the community today. From that moment, activity in Linea became full of life! ❤️‍🔥 We learned, made mistakes, tried new things - every single day! Without exaggeration, we started and ended our days together 🐸 Later, I became Frog of the Month alongside Cipresa and bilgute.eth🐸, and our leader, Sᕼᗩᘻᗩ, invited us to a conference in Brussels. That was something else! We attended the conference, side events, learned, worked, watched football, and drank beer together with Linea.eth! I was amazed at how close the team was to the community and how open everyone was. As time passed, I became even more involved in eFrogs and joined the team as a moderator. CROAK had already been launched, we were making new partnerships almost daily, we launched the new eFroglets collection, and we just kept building! We launched PondFun (and are now preparing for its revival). We met with Linea again, this time in Singapore at TOKEN2049, and even presented our project to vitalik.eth. Throughout the conferences, I was lucky to meet, listen to, and connect with so many amazing people Trantor, Suza, Declan Fox, Francesco Andreoli ᵍᵐ, cam, Big Iron Chris, alain.linea.eth, Ema // (🫰,✨), , ZeroLend - I’m even afraid to tag them all because I know they won’t fit in one message! We have so many friends, and it’s all thanks to Linea! The market can be tough, but challenges test and strengthen us. eFrogs keep building and bringing life to the Linea ecosystem. And we keep going because we believe in somETHing! Today, Ethereum Frogs 🐸 is celebrating a birthday! This year has flown by quickly and productively! 🐸💪 Happy birthday, eFrogs!

And this? This is the very first piece of... artificial limestone, YES, CaCO3, YES, hard as f and YES, waterproof, what I made from… Wood ash ONLY!!! 100% caveman tech! Now look at the color of this thing. How would you describe it? May I say it has the color of the pyramids? Hell yeah! Why? BTW: this is just the binder. Add original, natural limestone and fossils and you’ll en up with “natural” limestone. (With a bit of potassium residue.) Any questions? The secret recipe maybe? Anyone interested? Here you go: 1. Burn 🔥 everything around you and collect the wood ash 2. Burn natural limestone (calcination) to produce quick lime Steps 1. and 2. can be combined into one step. 3. Make wood ash lye the traditional way, by dripping drip 💧 water on wood ash and collecting the water that went through the ash. Any vessel will do but an oak barrel is the traditional way doing it. I used a plastic bucket with holes at the bottom. The wood ash lye is mostly KOH and K2CO3. What we need is CaCO3. We need to change the letter K to letters Ca. We’ll do it by adding the letters Ca to the liquid. 4. Add quick lime (CaO) or hydrated lime, slaked lime (Ca(OH)2) to the lye until it stops bubbling in vinegar. (We badly miss a decent video at this point, Marcell!!!) 5. Add (or don’t add) fossils = natural limestone rubble to the mix, stir well 6. Get rid of of the excess liquid through a nub Now any expert can tell you that this will never make a stone because of two reasons: 1. Billions of years and 2. High pressure are needed Well, no. The first point is just total nonsense, and although the second has something in it, it is false. Virtually ANY pressure will make it, including my current technique of squeezing it in a kitchen cloth. I’m not kidding. No pressure- no stone, that is correct. But only a minimal level of pressure, using my bare hands is enough to push the freshly made CaCO3 molecules close enough for crystallization (calcit) to begin. And here we are.show more

💥 This is an online briefing circulating about the... incident (The incident site was only about four miles from Zhongnanhai) : Incident No.: 2026-06-26-STFS-01 Incident Type: Suspected crash after loss of contact during general aviation local training Date of Incident: June 26, 2026 Time of Incident: 17:30–17:40 Location: Beijing Shifosi General Aviation Airport and the airspace near the East Fifth Ring Road to its west Operating Unit: Dongshi Shuangyue (Beijing) General Aviation Co., Ltd. Aircraft Information: Registration No. B-12PP Flight Personnel: Liu Junhua, a club member conducting a local solo flight I. Flight Overview This was a solo training flight by a club member within the local airspace, with the planned training subject being local takeoffs and landings. At 17:30, the aircraft took off normally from Shifosi Airport. At 17:40, as the crew prepared to return for landing and join the westbound traffic pattern for Runway 18, abnormal control behavior occurred. The aircraft did not properly enter the local traffic pattern. Instead, it continued maintaining a heading of 270 degrees due west and flew beyond the local controlled airspace. Local ADS-B monitoring continued until the aircraft reached the area near Beijing’s East Fifth Ring Road, after which its signal disappeared. The ground control tower then coordinated with regional approach control and Air Force control authorities, making repeated radio calls, but received no response. The aircraft lost contact. II. Key Timeline At 17:30, B-12PP took off from Shifosi Airport for a local solo training flight. At 17:40, it prepared to join the west-side traffic pattern for Runway 18 for approach and landing. The aircraft’s heading became abnormal, continuing on a 270-degree heading and flying westward out of the local airspace. The flight track reached the area near the East Fifth Ring Road, where the ADS-B signal was lost. Approach control and Air Force control were contacted, but the aircraft never responded by radio and was considered missing. III. Preliminary Risk and Problem Analysis Insufficient solo-flight control: The member was flying alone, without instructor monitoring, meaning there was no condition for intervention or emergency handling once a special situation occurred. Severe deviation from the flight pattern: During the approach phase, the aircraft failed to fly according to the standard traffic pattern. Its heading continued to deviate, causing it to cross the boundary and enter sensitive airspace over the city. Complete failure of communication and surveillance: ADS-B and radio communication failed, creating extremely high risk. Serious airspace safety hazard: A low-altitude general aviation aircraft crossed the boundary into the airspace above a built-up urban area, posing major safety risks on the ground. IV. Possible Causes Pending confirmation by official investigation Human factors: Pilot error, spatial disorientation, physical incapacitation, etc. Mechanical failure: Failure of the flight control system, engine, or electrical system, causing the heading to become uncorrectable and communication/surveillance to be interrupted. Equipment failure: Failure of ADS-B or the radio transponder, resulting in loss of signal and inability to establish contact. Some people online also found a photo of a Liu Junhua who is deputy general manager of the Discretionary Mandate and Solutions Department at CITIC Bank’s Asset Management Business Center, and claimed that she was the aircraft’s pilot. The building that was struck, China Zun — also known as CITIC Tower — is precisely where CITIC Group is headquartered. However, others have come forward saying that the pilot was not the Liu Junhua from CITIC. There are also two LinkedIn photos of Liu Junhua from CITIC in the comment section.show more

The importance of pointing the AirFanta Wear personal air... purifier accurately. You need to point the center of the Wear's airflow at your breathing zone. Otherwise you won't get any benefit from the device. This is just a visualization using the mist from an ultrasonic nebulizer to stand in for unfiltered ambient air. In the demonstration the air is not completely still due to the output of the nebulizer. But the air flow may be similar to cross currents that might be found in indoor settings. AirFanta has shown a number of different ways to position the Wear, but hasn't given exact numbers for distance as far as I know. I'm using a distance of 2 inches or less as a rule of thumb, with the center of the device pointed at my breathing zone. The 3/4 position feels like it's one that people may be the most interested in because it can let you eat while at the same time maintaining a close proximity to the output. The Wear is not meant as a one-to-one replacement for a respirator grade mask. It's best for situations where you were not going to be wearing a mask at all, but would still like to breathe cleaner air. Avoid risk compensation, which is where you take on more risk because you think you are more protected than you actually are. For instance, visiting a nephew sick with measles without an N95 mask because you think the Wear will give you equal protection. Maintaining the correct distance and orientation between the Wear and your breathing zone requires conscious effort. The Wear can reduce your overall exposure to airborne contaminants, but it needs to be used very close to breathing zone and needs to be very accurately centered.show more

The White House just put a 100% tariff on... foreign drones. The message: stop buying from China, start building at home. Powerus has been building at home the whole time, and its supply chain reflects it: a $30M strategic investment from $UMAC (as of this post, trading up 28%!), on top of an existing relationship supplying U.S.-made drone components. Kinetic counter-drone interceptors. Heavy-lift cargo drones. Tactical FPV platforms. Autonomous maritime systems. Manufactured out of Charlotte, North Carolina. The U.S. Air Force is already betting on it too: an IDIQ worth up to $90 million for the Guardian-2 interceptor. A defense prime followed with an order for 1,500 U.S.-made FPV aircraft. Powerus has proposed a merger with Aureus Greenway Holdings (Nasdaq: PUSA), targeted to close in Q4 2026 following SEC effectiveness of the Form S-4 on August 12th. The transaction remains subject to closing conditions, and there is no assurance it will be completed.
