@YannisTzortzis Yeah shipping is fast. However, maybe the product arrived from an EU facility?

No, I don't think that's the explanation. Even when KetoAF (85% fat carnivore) my ketones would be around 2-3 mmol/L not >4mmol/L. And I've played around with fat levels over the past year but my ketones wouldn't budge. Currently I'm adding fat, but not as much as my prior intake peaks. I'm probably around 75-80% fat right now. The last time I saw BHB >5 was early into keto when actively losing weight so I'm hoping that will be the explanation here 😂 Either way, I am guessing for some reason the B1 + carnivore combo is helping kick up fat oxidation and thus ketones as a side effect.

The EU's human rights chairman was caught with €600,000 cash in his apartment. He admitted it. 300 attempts to manipulate the European Parliament. €4 million from Qatar and Morocco.  5 years sentence. 4 suspended. Walked free. This is the institution that lectures you about democracy.

@0xHorseman @levelsio When you deny all ports, won't the current ssh connection fail? I was always worried by the idea of that happening.

Yep, good advice. Tailscale is great. Also best practices to disable root login, use ssh keys only (no passwords), use a cloudflare Zero-trust tunnel if you're exposing your deployer (e.g. you're hosting a PaaS like Coolify), start with a default deny udw policy on all ports and then open ports up as needed / access controlled only. Reverse proxies can be good too for an extra layer of logging with your auth. 0-dte vulns happen all the time.

You should never ever expose a VPS to the entire internet Always firewall it to subnets If you host a website you should only allow port 443 (HTTPS) inbound from Cloudflare's IP range / subnets Port 22 (SSH) only from your Tailscale subnet range That means you create a "tunnel" from Cloudflare and Tailscale (your laptop) to your server's door You still need your SSH key to open the door btw If you don't, ANYONE in the entire world can connect to your VPS and if there's just one security vulnerability and you didn't upgrade your VPS you can get hacked If you do have it firewalled with Tailscale subnet only, it means only if they hack your laptop they could get in via your Tailscale there Another thing is ask OpenClaw or Claude Code to enable unattended upgrades with auto reboot
William Benz@WilliamBenzDev

@levelsio Whats the point of installing tailscale? Or am I missing something here You could do the exactly same without tailscale

The healthiest habit in America is quietly destroying millions of knees. Walking 15,000+ steps a day builds your heart, your lungs, your endurance. It also loads the same five muscle groups in the same direction, 5.5 million repetitions per year, while the muscles responsible for keeping your knees from collapsing inward barely fire at all. Your body moves in three planes. Sagittal (forward and back), frontal (side to side), and transverse (rotation). Walking is almost entirely sagittal. Quads, hamstrings, glutes, calves: all getting hammered. Your adductors, the five muscles along your inner thigh, work in the frontal plane. They stabilize the pelvis, keep the knees tracking straight, and prevent the femur from drifting into varus alignment under load. During level walking, they activate at a fraction of their capacity. Along for the ride. Run that imbalance for a decade. The outer thigh gets progressively stronger. The inner thigh stays the same or atrophies. The knee joint, caught between two muscle groups pulling in opposite directions, starts absorbing asymmetric force with every single step. Cartilage wears unevenly. The medial compartment takes the hit first. This is how knee osteoarthritis develops. Knee OA now affects roughly 23% of the global adult population. In the US alone, surgeons perform nearly 800,000 total knee replacements per year at $30,000 to $50,000 each. That number is projected to hit 3.5 million annually by 2030. Patients with knee OA show 8 to 24% weaker hip abductor and adductor muscles compared to healthy controls. A longitudinal cohort study found that weaker hip muscles predicted faster OA progression. When the NHL gave players with weak adductors a 6-week strengthening program, injury rates dropped from 3.2 to 0.71 per 1,000 game exposures. 78% reduction from targeting one muscle group. The doctor telling this person’s dad to walk less is treating the symptom. The imbalance is the disease. Copenhagen planks, lateral lunges, side-lying adductions. Fifteen minutes, twice a week. That’s the difference between a $40,000 surgery and a body that can actually handle its own mileage.

PSA TO WALKERS! my dad used to walk like 15-20k everyday and his outer thigh muscles are much stronger than his inner thigh muscles which puts a lot of strain on his knees. his doctor told him to not walk as much/climb stairs and his knees hurt 24/7. do inner thigh workouts guys

You can prevent weight gain with a simple approach, without counting calories: avoid combining high fat and high carbs in the same diet. If you eat a high-carb diet, keep fat low. Elevated glucose suppresses fat oxidation, so dietary fat tends to be stored. If you eat a high-fat diet, keep carbs low. High fat impairs glucose metabolism, leaving glucose circulating longer, increasing lactic acid, blood pressure, and metabolic stress. Both approaches can work. The real problem is combining large amounts of both, since fats and carbs compete metabolically. And if fat intake is high, it should be mostly saturated fat, not PUFA, which adds inflammatory and anti-metabolic effects.

Και κάτι μου λέει πως έτσι στάσιμα και οπισθοδρομικά που έχουν γίνει αυτά που αναφέρεις, θα πρεπει να ιδιωτικοποιηθουν για να στρώσουν. Μλκ, πάμε καλά. Οι δρόμοι; Οι δρόμοι στην Ελλάδα είναι τριτοκοσμικοί, για να μην πιάσω τα άλλα. Βλέπεις εσύ καμιά κίνηση από αυτά που έκανε το κράτος; Όχι φυσικά. Ότι έφαγαν, τα άλλα χωμένα στον χρονοντούλαπο.

Ο καπιταλισμός δεν είναι τέλειος. Είναι όμως το μόνο που βασίζεται σε κάτι πραγματικό: ότι ο άνθρωπος κινείται από το ίδιον συμφέρον. Δεν του ζητάει να γίνει αλτρουιστής με το ζόρι. Τον αφήνει να δημιουργήσει, και στην πορεία δημιουργεί και για τους άλλους. Το κινητό, το φάρμακο, το αεροπλάνο, το σούπερ μάρκετ τον χειμώνα - τίποτα από αυτά δεν φτιάχτηκε από κρατικό σχέδιο πενταετίας. Φτιάχτηκαν γιατί κάποιος ρίσκαρε τα δικά του λεφτά, υπέθεσε ότι μπορεί να σου δώσει κάτι που θες, και για να το φτιάξει χρειάστηκε κόσμο. Δηλαδή δούλεψες κι εσύ, πληρώθηκες κι έζησες κι εσύ. Δεν είναι ιδεολογία. Είναι μηχανισμός.

Is Len Sassaman the REAL Satoshi Nakamoto? Buckle up, Bitcoiners. What if the creator of the world's biggest revolution died with the ultimate secret? Len Sassaman, cypherpunk legend, privacy warrior, gone too soon in 2011, fits the puzzle like a ghost in the machine. This isn't tinfoil. This is the theory that's exploding right now. Let's dive in... Picture this: It's 2008. Bitcoin whitepaper drops from "Satoshi Nakamoto." Who has the perfect resume? A guy who's been building anonymous systems since he was a teen. Len was maintaining Mixmaster — the gold standard for untraceable email. Adam Back (Hashcash inventor) once said Satoshi was probably a "remailer developer." Len was THAT guy. Coincidence? Or blueprint? 🔥 Timeline check: Len's in Belgium at KU Leuven, deep in the COSIC crypto lab. Satoshi's posts? British spelling ("grey," "maths," "flat," dd/mm/yyyy dates). Posting times line up with Belgian daytime. And get this, Satoshi went quiet during school terms... and ramped up on breaks. Len was studying. Mind blown yet? The smoking gun nobody talks about: the RARE BOOK. Bitcoin whitepaper cites obscure 1999 Belgian crypto papers (refs 2-5). Only available in KU Leuven library... where Len studied. Len even posted a Flickr pic with that exact book on HIS shelf. Satoshi had it. Len had it. Same place. Same time. 📚 Hal Finney connection: Hal was Bitcoin's FIRST recipient. They knew each other — Len worked on privacy tech with the same crew. Satoshi trusted Hal enough to send the very first coins. Len's inner circle? The exact cypherpunks who birthed digital cash dreams. This wasn't random. This was family. Len's genius level: Public-key crypto expert by age 22. Speaking at conferences. Building the tools that make Bitcoin possible. He obsessed over privacy, decentralization, taking power from banks — exactly Satoshi's manifesto. The whitepaper reads like his dissertation vibe. Clean. Precise. Revolutionary. Then the vanishing act. April 2011: Satoshi's last email, "I've moved on to other things." July 3, 2011: Len Sassaman dies tragically at 31. Forum posts stop cold. No more updates. No more clues. The creator vanishes the exact moment Len leaves us. Chills. Bonus: After Len's death, the Bitcoin community embedded a memorial in the blockchain itself. A tribute from his friends, right there in the ledger he might have invented. Poetic? Or a final wink from the man behind the mask? Len lived for anonymity. Never chased credit. Never cashed out. If anyone could create $1T+ empire... then walk away forever to protect the vision? It was him. Privacy above glory. That's the cypherpunk way. The evidence keeps stacking. The book. The timing. The tech. The silence. What if Satoshi didn't disappear... he just went home? Look, we'll never know for sure (that's the point of Bitcoin). But Len Sassaman? The clues line up too perfectly to ignore. A hero who coded freedom, then let the world wonder. Respect. 🫡 Your turn, crypto Twitter: Is Len Satoshi? Drop your wildest evidence or counter-theory below 👇 RT if this thread just made you question everything

Ένας πολύ καλός λόγος να προτιμούμε ελληνικές σοκολάτες. Ή´ αλλιώς, ένας διατροφικός εφιάλτης προ των πυλών Από το αγρόκτημα στη δεξαμενή: Η άνοδος του κακάο που «καλλιεργείται» σε εργαστήριο και η κατάρρευση των προτύπων ποιότητας σοκολάτας Η βιομηχανία σοκολάτας βιώνει μια ιστορική μετατόπιση, καθώς παγκόσμιοι κολοσσοί όπως η Mondelēz International χρηματοδοτούν ισραηλινές εταιρείες βιοτεχνολογίας, όπως η Celleste Bio, για την παραγωγή κακάο κυτταροκαλλιέργειας, με την επίσημη κυκλοφορία να αναμένεται έως το 2027. Λόγω της πρωτοφανούς αύξησης των τιμών του κακάο η οποία εκτοξεύτηκε λόγω των κλιματικών επιπτώσεων στη Δυτική Αφρική, η παραγωγή κυττάρων κακάο σε φαρμακευτικούς βιοαντιδραστήρες θεωρείται ως μια «ανεξάρτητη από το κλίμα» και οικονομικά αποδοτική εναλλακτική λύση σε σχέση με την παραδοσιακή γεωργία. Εξελισσόμενα πρότυπα και συστατικά: • Υποκατάσταση φυτικών λιπαρών: Μάρκες όπως η Cadbury χρησιμοποιούν εδώ και καιρό έως και 5% φυτικά λιπαρά εκτός κακάο (π.χ. φοινικέλαιο, καριτέ) σε αγορές όπως το Ηνωμένο Βασίλειο, μια πρακτική που επιτρέπεται από τους κανονισμούς της ΕΕ, αλλά συχνά επικρίνεται ως αραίωση της «αληθινής» σοκολάτας. • Αμερικανικά έναντι διεθνών προτύπων: Η αμερικανική σοκολάτα γάλακτος απαιτεί μόνο 10% υγρό σοκολάτας και 3,39% λιπαρά γάλακτος, σημαντικά χαμηλότερα από το 25% στερεά κακάο σε ξηρή μορφή που ορίζουν τα πρότυπα του Ηνωμένου Βασιλείου/ΕΕ. • Ανησυχίες για την υπερεπεξεργασία: Πρόσφατες ανεξάρτητες εργαστηριακές εκθέσεις έχουν επισημάνει ανιχνεύσιμα ίχνη βαρέων μετάλλων όπως ο μόλυβδος και το κάδμιο σε αρκετές μάρκες σοκολάτας, συμπεριλαμβανομένης της Cadbury, μαζί με προειδοποιήσεις σχετικά με τον υψηλό βαθμό βιομηχανικής επεξεργασίας. Αυτή η μετάβαση προς συστατικά με βάση τα κύτταρα αντιπροσωπεύει μια θεμελιώδη αλλαγή στην παγκόσμια αλυσίδα εφοδιασμού τροφίμων, όπου η βιομηχανική αποδοτικότητα γίνεται ολοένα και περισσότερο προτεραιότητα έναντι της παραδοσιακής γεωργικής προέλευσης. x.com/WallStreetApes…

Neither of these men are married or have kids. Both are simply obsessed with their own personal perfection and optimization. There is nothing impressive about a single man with no kids sleeping well and being fit. Show me a man with young children, a full time job, disrupted sleep, who works out regularly, eats healthy, trains Jui Jitsu, with a muscular body… THIS is impressive. THIS requires extreme discipline.
Camus@newstart_2024

Chris Williamson just shared his "nuclear" sleep stack that's quietly changing his life—and Andrew Huberman breaks down exactly why it works: If you're lying in bed at 2 a.m. scrolling or staring at the ceiling, this 4-minute protocol combo might be the fastest way to shut your brain off without pills. The two killer techniques Williamson swears by: 1. The Mind Walk (visualization on steroids) - Imagine walking a route you know perfectly (your house → front door → street) - Do it with insane detail: feel the shoehorn, hear the key turn, feel the door handle, pressure of the pavement - It's like reading fiction for your nervous system—engages the brain just enough to stop problem-solving loops, but not enough to keep you awake 2. Resonance breathing with the Ohm stone lamp - Bedside lamp with induction-charging stone that has a built-in FDA-cleared HRV sensor - Hold the stone → 3/6/9/12-minute guided sessions with silent tactile vibration (no sound, no light, partner-safe) - Guides you into true resonance frequency (max vagal tone) → the stone knows when you hit it - Williamson calls it “the sickest” sleep tool he’s ever used—currently in stealth (ohmhealth, not widely available yet) Huberman adds the neuroscience: Looking down + eyelids lowering activates parasympathetic circuits and deactivates wakefulness-promoting brainstem nuclei. It’s literally pedaling the sleep pedal while shutting off the alertness arm. Williamson: “Some days you need the adventure story (mind walk), some days you need the physiological hammer (resonance breathing). Stack them and I’m cross-eyed into sleep.” Already trying one of these? Or is your nighttime routine still a war zone?
