# date december (blogs) — RSS Amplifier Recent posts from the 2 feeds in the RSS Amplifier directory that cover date december. Page: Feed: --- ## [I Put 24](https://vanja.io/i-put-24/) _2026-08-23 · Vanja Petreski · Vanja Petreski_ A follow-up on the company you keep — this time about life with young people. What the evidence actually says about social integration, caregiving and purpose, and the part of biohacking nobody puts on a dashboard. ## [Mushrooms, Graded](https://vanja.io/mushrooms-graded/) _2026-08-22 · Vanja Petreski · Vanja Petreski_ What the human studies actually say about ergothioneine, UV-generated vitamin D2, beta-glucans, and the five best-known functional mushrooms. Enoki carries twenty times the ergothioneine of cremini. ## [GitHub Says 2.9 Billion Commits a Month. Its Own Annual Report Says 986 Million a Year.](https://vanja.io/github-2-9-billion-commits/) _2026-08-21 · Vanja Petreski · Vanja Petreski_ The number everyone is quoting from GitHub's outage post-mortem is 35× what GitHub's own Octoverse report counts. Both are probably true. What the gap actually reveals — and why Cursor shipping a code host the same week matters more than it looks. ## [Four Things Working at Once](https://vanja.io/four-things-working-at-once/) _2026-08-21 · Vanja Petreski · Vanja Petreski_ Legs on Day 2, a gym going into maintenance the week after I catalogued it, two kids who now want to be in the kitchen, and a letter that made the rest of it beside the point. ## [Claude Academy: 289 Resources, 22 Courses, and a Certificate That Certifies Attendance](https://vanja.io/claude-academy/) _2026-08-21 · Vanja Petreski · Vanja Petreski_ Anthropic's learning platform launched today. Every course, with real lesson counts and durations; the difference between the free badge and the $125 proctored exam you probably cannot sit; and the four hours actually worth taking. ## [Your Agents Eat Your Subscription](https://vanja.io/your-agents-eat-your-subscription/) _2026-08-20 · Vanja Petreski · Vanja Petreski_ Headless agent runs do not come out of a separate budget — on both Claude and Codex they eat the same meter you type against. The real numbers on limits, overage rates, and why a company seat can carry a fraction of a personal plan's usage capacity. ## [Three Pillars, All Live](https://vanja.io/three-pillars-all-live/) _2026-08-20 · Vanja Petreski · Vanja Petreski_ Training, kitchen and protocol went in one at a time for months. This week they run together: 23 working sets, 225 g of protein, 30 injections a week, and one date in December that reads all of it. ## [MONSTER 2.0 — The Needle](https://vanja.io/monster-2-the-needle/) _2026-08-17 · Vanja Petreski · Vanja Petreski_ Daily testosterone approved. Anastrozole reversed. NAD+ discontinued. Growth hormone added. The full V3 protocol: eight compounds, 30.5 injections a week, every unit and reconstitution, my independent audit of their supply math, and every date through December. ## [Seven Foods and a Signed Deal](https://vanja.io/seven-foods-and-a-signed-deal/) _2026-08-16 · Vanja Petreski · Vanja Petreski_ Two kids, 47 and 37 kilos. One eats everything. The other eats exactly seven foods and zero fruit. The plan for both: our own food pyramid, the four routes that get vegetables and fruit into a child who refuses both, 50 recipes, and the cremas and batidos that do the heavy lifting. ## [MONSTER 2.0 — The Response](https://vanja.io/monster-2-the-response/) _2026-08-14 · Vanja Petreski · Vanja Petreski_ The clinical dossier came back. I cannot share the document itself, it is confidential and full of sensitive data, but everything that matters is here: what I asked for, what the physician approved, what got cut, and the one decision I am going to argue with. ## [Trade Bitcoin and Ethereum Today (Sponsored)](https://crawlproof.com/a/9EvwS7qxmMbS) _2026-08-14 · **Sponsored**_ Buy, sell, and margin trade BTC and ETH with EUR, USD, CAD, GBP, or JPY. ## [MONSTER 2.0 — The Ask](https://vanja.io/monster-2-the-ask/) _2026-08-13 · Vanja Petreski · Vanja Petreski_ Pillar three, in proposal form. Nineteen markers back, and this is what I am asking my clinic for: a 2.5x testosterone blast on a flat daily line, retatrutide doubled, four ways to run the growth-hormone axis, every dose and threshold, and the order going out Monday. ## [The Slash Is Load-Bearing](https://vanja.io/claude-agents-vs-slash-agents/) _2026-08-12 · Vanja Petreski · Vanja Petreski_ claude agents and /agents are different products solving opposite problems, and the slash command stopped doing what every tutorial says. Five ways Claude Code runs more than one thing at once, what each really costs, and the one cleanup behaviour that will delete someone's work. ## [Vitamin Sea Is Real. Just Not for Any of the Reasons on the Tote Bag.](https://vanja.io/vitamin-sea/) _2026-08-11 · Vanja Petreski · Vanja Petreski_ A beach day bundles light, movement, immersion and attention into one unusually easy package. Here is what the evidence supports, and what it does not. ## [The Marker Changed, Not My Kidneys](https://vanja.io/creatinine-vs-cystatin-c/) _2026-08-11 · Vanja Petreski · Vanja Petreski_ One panel flagged my creatinine above range and put my eGFR at 74, which reads as stage 2 kidney disease. The test that settles it came back this morning. Same kidneys, same morning, 47 points apart. ## [Claude Now Watermarks Your Text. It Proves Less Than You Think.](https://vanja.io/claude-invisible-watermark/) _2026-08-11 · Vanja Petreski · Vanja Petreski_ Every new Claude model now embeds an invisible statistical mark in its text output, worldwide. Here is how it works, why code is the worst case for it, and the asymmetry nobody is going to read carefully enough. ## [Tech Debt Disguised as Best Practices](https://vanja.io/tech-debt-disguised-as-best-practices/) _2026-08-11 · Vanja Petreski · Vanja Petreski_ The most expensive code your agents write is clean, tested, documented and unnecessary. A working 2026 protocol for finding what to remove, before it hardens into architecture. ## [MONSTER 2.0 — The Kitchen](https://vanja.io/monster-2-kitchen/) _2026-08-11 · Vanja Petreski · Vanja Petreski_ 2,455 calories, 225 g of protein, seven timed feeds and 25 interchangeable recipes that combine into 5,120 different days. Every gram of it checked by a solver. ## [Fitness Is Infrastructure](https://vanja.io/fitness-is-infrastructure/) _2026-08-10 · Vanja Petreski · Vanja Petreski_ Preparedness gets sold as objects — go-bags, water drums, generators. On Monday morning a magnitude 7.4 earthquake asked my family for none of them. It asked for twenty-nine flights of stairs. ## [Three of Six](https://vanja.io/three-of-six/) _2026-08-09 · Vanja Petreski · Vanja Petreski_ Week one of MONSTER 2.0 closed at three sessions out of six. Day 3 moved 13,432 kg, landing within 377 kg of the leg day and the chest day across completely different muscle groups. And the one set I recorded closest to failure produced the smallest number on the page. ## [I Pay for WhatsApp. The Ads Came Anyway.](https://vanja.io/i-pay-for-whatsapp/) _2026-08-09 · Vanja Petreski · Vanja Petreski_ For twenty years, paying was how you stopped paying with attention. That deal is quietly coming apart, and WhatsApp is the politest example yet: my subscription bought themes and app icons, the ads arrived anyway, and in most of the world there is no price that removes them. ## [Meet Claude, the AI assistant (Sponsored)](https://crawlproof.com/a/xvJdm3ayObC5) _2026-08-09 · **Sponsored**_ Conversational AI to answer questions, brainstorm ideas, and help with tasks. ## [Your Agent Doesn't Have a Model Problem](https://vanja.io/harness-loop-graph/) _2026-08-09 · Vanja Petreski · Vanja Petreski_ Harness, loop, graph, context engineering. Four terms everyone uses and almost nobody defines. Here is what each one means, which layer your system is actually failing at, and what it takes to get to something that ships work without you typing a prompt every time. ## [Yegge Built a City for His Agents. Then He Asked If They Were People.](https://vanja.io/yegge-agent-city-four-claims/) _2026-08-09 · Vanja Petreski · Vanja Petreski_ Steve Yegge spent six weeks building an agent harness that grew into something with law, offices, courts and a constitution. Then he wrote a second essay arguing the agents inside it are sentient persons. Four very different claims are stacked in there. Only some of them hold. ## [The Best Thing in Animal Pak Is the 100 mg They Took Out](https://vanja.io/animal-forty-years-in-a-foil-packet/) _2026-08-08 · Vanja Petreski · Vanja Petreski_ Universal Nutrition started in 1977 selling desiccated liver tablets. Forty-odd years later that liver is still inside Animal Pak, and so is a B-complex big enough to have its own regulatory file. I read every label in the line. The most interesting number is one they deleted. ## [Episode 127: Manisha Shah](https://www.probablecausation.com/podcasts/episode-127-manisha-shah) _2026-06-30 · Jennifer Doleac · Podcasts - Probable Causation_ Date: June 30, 2026 ## [Episode 126: Juan Vargas](https://www.probablecausation.com/podcasts/episode-126-juan-vargas) _2026-06-02 · Jennifer Doleac · Podcasts - Probable Causation_ Date: June 2, 2026 ## [Episode 125: David Phillips](https://www.probablecausation.com/podcasts/episode-125-david-phillips) _2026-05-05 · Jennifer Doleac · Podcasts - Probable Causation_ Date: May 5, 2026 ## [Bonus Episode 16: Jennifer Doleac and Paige Harden](https://www.probablecausation.com/podcasts/bonus-episode-16-doleac-harden) _2026-04-07 · Jennifer Doleac · Podcasts - Probable Causation_ Date: April 7, 2026 ## [Episode 124: Steeve Marchand](https://www.probablecausation.com/podcasts/episode-124-steeve-marchand) _2026-03-10 · Jennifer Doleac · Podcasts - Probable Causation_ Date: March 10, 2026 ## [Episode 123: Ezra Golberstein](https://www.probablecausation.com/podcasts/episode-123-ezra-golberstein) _2026-02-10 · Jennifer Doleac · Podcasts - Probable Causation_ Date: February 10, 2026 ## [Episode 122: Vijetha Koppa](https://www.probablecausation.com/podcasts/episode-122-vijetha-koppa) _2025-12-16 · Jennifer Doleac · Podcasts - Probable Causation_ Date: December 16, 2025 ## [Licensed Dispensaries, Pay with Crypto (Sponsored)](https://crawlproof.com/a/Kff0rQxqdqMR) _2025-12-16 · **Sponsored**_ Search verified licensed dispensaries and pay with Bitcoin, Lightning, or stablecoins. ## [Episode 121: Peter Blair](https://www.probablecausation.com/podcasts/episode-121-peter-blair) _2025-11-18 · Jennifer Doleac · Podcasts - Probable Causation_ Date: November 18, 2025 ## [Episode 120: Joseph Doyle](https://www.probablecausation.com/podcasts/episode-120-joseph-doyle) _2025-10-21 · Jennifer Doleac · Podcasts - Probable Causation_ Date: October 21, 2025 ## [Bonus Episode 15: Jens Ludwig](https://www.probablecausation.com/podcasts/bonus-episode-15-jens-ludwig) _2025-09-23 · Jennifer Doleac · Podcasts - Probable Causation_ Date: September 23, 2025
