Research in Finland found that simply changing what children play on can quickly influence their immune system. Scientists redesigned parts of nursery playgrounds by swapping gravel and asphalt for natural forest materials, soil, moss, leaf litter, and native plants, so kids would be exposed to the microbes found in nature. After just 28 days, clear biological differences emerged. Children who played in these “rewilded” spaces developed a richer mix of microbes on their skin and in their gut. They also showed higher levels of regulatory T-cells, which help the body manage inflammation and reduce the risk of immune overreactions like allergies. These changes were not observed in children who stayed on conventional playground surfaces. The findings support the biodiversity hypothesis, the idea that limited contact with natural environments, especially in urban life, may be linked to rising allergies and autoimmune conditions. What stands out is how simple the intervention was. This wasn’t extreme outdoor exposure-just everyday play in a more natural setting. Even small, regular contact with soil and vegetation appears to shape the body’s internal ecosystem and how the immune system develops.

@ValerieAnne1970 @grok research deeply if this is accurate and if positive list source links.

You think you're just eating "cheese"? Think again. 90% of the American cheese on store shelves right now is made with a lab-engineered fake rennet called FPC — fermentation-produced chymosin. And it was originally developed and patented by Pfizer in 1990. Yeah, *that* Pfizer. Here's how they did it: They took the gene for chymosin (the key clotting enzyme from a calf's stomach), spliced it into Aspergillus Niger — black mold — using CRISPR gene-editing tech, then let the mold ferment in giant vats like some dystopian bio-reactor. The result? A synthetic enzyme that's cheaper, faster, and more consistent than the real thing. Big Food loved it. No more baby calves. No supply limits. Just endless, uniform cheese bricks rolling off the line. FDA called it "substantially equivalent" to real rennet and gave it GRAS status with zero long-term human safety studies — just a 90-day rat trial. Sound familiar? The worst part? This stuff isn't even listed properly. On ingredient labels it hides behind vague wording: - "enzymes" - "microbial enzymes" - "vegetarian rennet" - or just plain "rennet" And here's where it gets insidious: Plenty of people are getting bloating, digestive distress, skin issues, or straight-up allergic reactions after eating cheese... and they blame "dairy." But a growing number are realizing it's not the milk — it's the A. Niger residue or the GM process itself triggering the problem. Real animal rennet? That's the traditional calf-stomach enzyme our ancestors used for thousands of years. It works with your body. No hidden mold genes. Want the real stuff? How to actually avoid this garbage: - Look for labels that specifically say "animal rennet" or "calf rennet" - Skip anything that says "microbial," "vegetarian," or just "enzymes" - Buy European imports, artisanal, or raw-milk cheeses (they still use the old-school stuff) - Certified Organic or Non-GMO Project Verified is safer (many ban FPC outright) - Best move: find a local cheesemaker who tells you exactly what they use They turned one of the oldest, most nutrient-dense foods on earth into another ultra-processed Franken-food and hoped you'd never notice. Stop eating their science experiment. Your gut (and your ancestors) will thank you.

I don’t review code written by agents. I measure things like test coverage, dependency structure, cyclomatic complexity, module sizes, mutation testing, etc. Much can be inferred about the quality of the code from those metrics. The code itself I leave to the AI. Humans are slow at code. To get productivity we humans need to disengage from code and manage from a higher level.

@Grady_Booch @pmarca wins... Why? Well... chatgpt.com/c/69d27245-215…

Marc is profoundly wrong, in every dimension of the word wrong.

@rwiteshbera @eatonphil Yes, why would people that already has read 1st edition should check 2nd edition?

@eatonphil How is this second edition different than first one?

I first tried to read this book in 2018 and couldn't make it through because I thought it was too hard. 8 years later it's the only book I recommend every developer reads, and I had the chance to review the 2nd edition. Join a study group, give it a read.

Jonathan Haidt dropped a pretty blunt warning about giving young kids iPads or phones. He says we’ve all discovered how incredibly effective they are as pacifiers — they work almost instantly. But that’s exactly the problem. 40% of American two-year-olds already have their own iPad. Once a child gets used to constant stimulation, they basically never learn how to be bored. The moment they have even 30 seconds of downtime, they start screaming for the device. Haidt’s advice is straightforward: If you haven’t started, don’t. If you already have, take it away. It might take 3–4 weeks for the brain to readjust, but it’s worth it. He’s even hearing stories of preschoolers crying at drop-off — not because mom is leaving, but because the iPad is staying in the car. It’s a sobering reminder of how quickly these devices rewire young brains and create real addiction patterns. Have you noticed this with kids in your life, or are you trying to hold the line on screens with little ones?

Funniest part of it that this was mostly Brazilians with Italian heritage getting passports A demographic that's high educated and high income and culturally aligned with Italy and Europe, I mean they're genetically Italian! Instead they'll now give away passports to low educated welfare seekers without income from cultures that hate them It seems European governments enemy is immigrants that are a net positive addition to their culture while wanting to bring in more people that want to destroy their societies

@PallottaPedro @dcoderio Se a gente começar a denunciar esse tipo de conteúdo errôneo as coisas vão melhorar...

@dcoderio Além de ter falado uma imensa asneira, nenhuma das fontes que você citou disse isso.

"8GB no mac rende como 16GB no windows" não. o macOS usa swap agressivo no SSD pra compensar a falta de RAM. no macbook neo, o SSD é até 8x mais lento que no macbook pro resultado: seu notebook de R$3.000 vai degradar o SSD em velocidade acelerada fazendo o trabalho que 8GB extras de RAM fariam sem desgaste nenhum a apple resolveu o problema do preço criando um problema de longevidade. isso não é engenharia elegante, é trade-off que o consumidor não foi informado

@unclebobmartin Hyper threading? Amazes me that I always thought you were a MacIntosh man🤔

In the last three days I have: 1. Designed and implemented a complete JVM language that Codex believes (whatever that means) would be ideal for AIs to use regardless of what humans think about it. It compiles down to JVM bytecode. 2. Designed and build, from scratch, a wiki with it's own internal web server and fully described by Gherkin style acceptance tests. 3. Made significant updates to the computer strategy of the Empire game. 4. Produce the crap4java and mutate4java tools that I used to help build the wiki. 5. Conceived of and implemented the differential mutation strategy used in both my clojure and Java mutation tools. And for every one of those projects I implemented a strict TDD, ATDD, Crap, and Mutate workflow that forced coverage into the high 90s, kept Crap below 8, and split any files with more than 50 mutation sites. My poor laptop had all 16 (8 hyperthreaded) cores burning at 100%. The fan was raging the whole time. I was hopping from window to window overseeing the entire campaign. It was exhausting! Did that workflow slow the process down? Probably. Probably a lot. On the other hand all these projects maintained rigorous semantic stability, with all unit tests, and acceptance tests passing. I never ran the wiki until it was done. It worked first time. I never compiled a program with AIR-J until it was done. It worked first time. No bugs have been introduced into the Empire game (so far). And that, boys and girls, is a freaking miracle.

@JohnOfProgress @JasonBotterill That'd be amazing!!! I remember playing it while tuning one of the game radio stations playing "leitmotiv Walkürenritt" by Richard Wagner!

@JasonBotterill Can you please ask it to make simcopter work again

Dude I am fucking crying. I put a Halo ISO file in a folder and told Codex to make it playable on Mac. I left it running and I got jumpscared by suddenly hearing the Halo music theme blast out my speakers

@ericksalzerr @grok onde fica o repositório de código desse programa que é falado durante a reportagem?

If I tried to explain the wild scandal involving a fraudulent Brazilian bank (Banco Master), its billionaire psychotic owner now imprisoned, and Brazil's tyrannical judge, you'd think I was exaggerating. For now: Elon Musk's prediction may be closer than ever to materializing.
