The Special Session at Shibuya Hikarie: infinities and renormalisation, Hawking's information problem, holography (“100 squared, not 100 cubed”), Nomura's dark matter papers this year, and a “weak measurement” backstage.

Compare Even G2, Mentra Live, Halo, RayNeo and Meta Display, plus Chinese products, US-only retail and crowdfunding. Find out which offer custom endpoint settings, which require SDK development, and which remain unverified for your own uncensored model.

Put your phone on the desk. The camera watches how open your eyelids are, and if they stay shut for five seconds it wakes you with sound, vibration and the screen. Blinking doesn't set it off. It works through earphones and gets through silent mode. The video never leaves your device.

Two RTX PRO 6000 Blackwell cards (96GB each) — the practical ceiling of what an individual can buy. Runs Qwen3-235B and Llama 405B-class models on your desk. Full parts list, reasoning, and electrical realities, priced September 2026.

Search Mercari, Yahoo! Auctions, Yahoo! Flea Market and Rakuma at once, paste a listing, and see whether it's a great deal, fair, or overpriced against September 2026 sold prices. Compares the V100 32GB, RTX 3090, modified 3080 20GB and EVO-X2 by use, with Qwen4-27B in mind.

A ranking of fifty living great minds — Penrose, Witten, Tao, Deutsch and the pioneers of AI and biology — with their achievements, books, talks and social media. Latest papers are fetched live from the arXiv API.

Lunch, chores, turns, who pays — spun by bits from IBM quantum hardware. The server commits to the bits before it knows how many options you have, so it cannot steer the result. It also includes a live demonstration that ordinary random numbers are just computed from a seed. Open source.

Android Auto and Android Automotive OS share a name and nothing else. This follows one vehicle signal all the way up through the VHAL to the app — plus GAS certification, the barely-documented Carma program, and the 2026 Gemini migration. A developer's map, built from public sources only.

A concentration game with face cards and name cards. Names are hard not because your memory is bad, but because a name has nothing to attach to (the Baker-baker effect). So this trains only the attaching. Reaction time and accuracy become a rank. Free in the browser, no account.

The Thinker pose with a footstool, a fibre counter against Japan's 2025 targets, the Bristol stool scale, a toilet timer and warning signs.

Work back to a bedtime from your wake-up time, check pillow height, mattress firmness, seven before-bed habits, and when to see a sleep clinic.

Is it a lie-in-the-sun day? judged from UV, temperature and cloud. Save rooftop benches, park lawns and the balcony recliner as your sunny spots, and breathe spread-eagle with a timer.

Scripture for lovers of the lying bath (neyu): seven rules for safe bathing, how to find a neyu, a pilgrimage log, a soak timer and the spring types.

Causes and fixes for feet, armpits, scalp and neck, age-related odour and breath. Foot odour is bacteria and damp, not sweat. Shoe rotation and daily care.

Enter your check-up numbers and each is sorted by Japan's Ministry of Health thresholds. Find the cancer screenings for your age and sex, and the signs that mean call 119 now.

A leaving check where you point at each item at the door (daily, work, travel, rainy day — editable), where-I-put-it notes, three things before you get off, and what to do when something is lost.

A compass for which way you face, save your hotel, car or station exit and get an arrow and distance back, and record the route you walked to return to the start. Location stays on your device.

A full-screen help card for when you cannot speak (with read-aloud), audio recording to keep evidence (saved on your device), and what to do when harassed, groped, wrongly accused, in an on-board attack, delayed or when someone falls.

Check whether a password has leaked without sending it. Strength estimate, strong password generator, inspect suspicious links before opening them, a 12-point checklist, and the first hour after a hack.

Find and remove the location hidden in your photos, sweep for hidden cameras' infrared with your phone, audit AirTags, stalkerware, location sharing and signed-in devices, and spot industrial-espionage recruitment. Nothing leaves your device.

Harari's three goals as tools for today: score the eight numbers that extend life (AHA Life's Essential 8), measure wellbeing with WHO-5, and sort enhancement technologies by evidence. With a weekly upgrade plan.

Ukraine's Air Alert and Israel's Home Front Command, rebuilt for Japan. Press on an alert and it shows only the refuges you can still reach in time. JMA warning log, Yokohama's 515 water points and 454 disaster bases, family check-in with no location sent, printable PACE plan and offline save.

What survived the 1945 bombing of Tokyo lay far from strategic targets, shielded by temples, cemeteries, gardens and rivers. This map applies that rule to today's military sites, power plants, fuel depots, ports and airports, plus flood, tsunami, landslide, wetland, earthquake and lightning data, and paints a sanctuary score. Includes a before (1936–42) ⇄ after (1945–50) aerial photo swipe and 5,113 Tokyo missile shelters.

A map that runs on Japan's public geodata alone. Tap a point for elevation and nearby high ground, the nearest designated evacuation sites, flood/tsunami/landslide hazards, estimated nuclear-blast rings with downwind fallout, and 1945 US aerial photos of bombed Tokyo. First-10-minutes guides for nuclear, missile, drone and rogue-AI scenarios, plus comms, water, food and self-protection. No sign-up; your location stays on the device.

Survive a Japan overrun by AI robots and autonomous drones — where your phone's accelerometer, microphone, compass, vibration and radio state are the actual game mechanics. Shake the phone and robots close in on the vibration; make a sound and drones swarm. The machines are enemies of each other, and the human's only weapon is hiding. Free in the browser, no sign-up, works offline.

Smoking, drinking, social media, late nights — you decide what to quit. But there's no streak counter. A number that resets to zero turns one slip into "it's all ruined." Over the same 90 days, one counter says "day 10," the other says "83 days done" — a chart at the top draws both lines so you can see the gap for yourself.

A weekly ranking of papers published in the last 90 days that have already picked up citations, across consciousness & brain, AI, physics, life sciences and mathematics. Sourced from OpenAlex, with open-access links where they exist.

Mount your phone, record yourself flipping through a book, and Pagedive pulls out every page into a PDF. It all runs on your device — no video or image is ever uploaded. It is the video method from "Turning Books into Text", built.

The fifteen wealthiest people in the world and the fifteen wealthiest in Japan — fortunes, social media and books for each, with their latest moves fetched live from Google News and YouTube.

Four small games meant to be played in the bath, built so they still work through a waterproof case. Splash rhythm, tub diving, growing steam, and the hammer bath.

True random numbers from an IBM quantum computer pick the one koan you need today. No fortune, no answer. Once a day, the universe takes a look.

App Store data on 50 well-known board games: which have real digital versions and how they charge. Free-to-play is almost entirely absent from this category, for a structural reason — and the titles most famous in Japan have no app at all.

Pick giveaway winners, seating or turns using bits from IBM quantum hardware. An ordinary random number is computed from a seed, so whoever holds the seed already knows the result — a quantum measurement isn't determined by anything before it. Every draw produces a certificate anyone can recheck.

Destinations rewritten as an Ising model and put through quantum interference — bad itineraries cancel, good ones reinforce. The 64 measurements that collapse the superposition use bits from real IBM quantum hardware. What is quantum here and what isn't is spelled out in full.

Does free will exist? Papers collected from Crossref, weighted toward the side arguing against hard determinism — while still listing the leading sceptics in the same place. Includes an interactive reconstruction of the Libet experiment and Schurger's drift model.

Practical knowledge about Claude Code and other coding agents, collected daily from Zenn, Qiita, Hacker News and Reddit. Filtered for the things that aren't in the docs: configuration, workflow, and what went wrong. Headlines and links only — no reposting, no translation of anyone's text.

There is no way to reliably prevent dementia. But the Lancet Commission (2024) reports that around 45% of cases are associated with 14 modifiable risk factors. This covers only the part you can move, sorted by strength of evidence. No supplement links — nothing has been shown to work.

Cut and scan, shoot page by page, or film yourself flipping through. Compared on time, cost and accuracy — plus the unusual Japanese rule that doing it yourself is legal but paying someone is not, and a breakdown of what the video approach actually demands.

Racquets drop to about half price one generation back. But the item that actually dominates annual cost is strings. Includes a calculator for single packs vs reels vs owning a stringing machine. It never claims a "cheapest" price — prices move, buying strategy doesn't.

Looking presentable isn't taste — it's the absence of things that read as neglect. Eight items ordered by how much they move the needle: hair, brows, clothes, skin, glasses, posture, smell, expression. Notably, it tells you when to stop.

Musk / xAI, Amodei / Anthropic, OpenAI, Google DeepMind, Singularity Salon and the major AI communities — news, videos and official blogs collected every 30 minutes onto one page. The second half is a dated list of AI perks a university email unlocks: Google AI Plus free for a year, the GitHub Student Pack, free Matsuo Lab courses — and the offers that have quietly closed.

77 YouTube channels that actually served as groundwork for the pages here, sorted into eight fields: brain and BCI, physics and cosmology, mathematics, research institutions, philosophy, programming, the body, and general curiosity. Faster than a textbook, gentler than a paper.

Wireless, maps, GPUs and storage built by individuals and tokens instead of one company: the token flywheel, a map of the main projects, and what you see when you split rewards from revenue. No investment advice.

The “chosen” that new students hear at a Christian school's entrance ceremony is about a task, not a privilege. The verse behind it (John 15:16), the Methodist view, the motto “Salt of the Earth, Light of the World,” and a 150-year timeline from three small mission schools.

Bell-certified quantum bits, uranium-238 and potassium-40 decay, a qubit on IBM hardware, the thermal noise inside a CPU, and pseudorandom generators — ten sources scored on the same four axes: freedom from determinism, resistance to an insider, third-party verifiability, and how little you must trust. Only one method can prove, by theorem, that even its builder could not know the next bit.

Randomised allocation for clinical trials and psychology experiments. The allocation table is sealed at generation and only its hash is published; you open one entry per participant and disclose the whole table when the study ends, so anyone can check it against the pre-registered hash. Random bits come from real IBM quantum hardware. Free.

Everything here was built by talking to a coding agent. Anyone can start for $20 a month. What it can and cannot do (images and video: it writes the programs that make them), and how to publish on Vercel or Cloudflare, with real examples.

Jet suits really fly. Full-body exoskeletons are products. Only the arc reactor is missing. Ten abilities from the films graded against real products and research: real today, partly, in the lab, not soon.

A person climbed a glass wall on gecko-style adhesive. Artificial spider silk is clothing. Liquid that turns to thread in mid-air exists. Strength, healing and reflexes have barely moved. Nine abilities graded.

Flutter apps, small games, and the collection scripts behind the trackers.
