• Why You Can Play Full Games in Your Browser Now
  A decade ago a browser game meant a small flash puzzle; today it can mean a 3D world with physics, multiplayer and a leaderboard — no install, no app store, no download bar. This quiet revolution came from three technical shifts most players never noticed. Here is how the browser became a game console.
• Why No Website Can Be 100% Unblockable (And What to Do About It)
  Any government can filter a domain, an IP, or a TLS fingerprint — the realistic goal is not invulnerability but redundancy: several independent doors to the same content.
• Tukuk-OS Bug Retrospective: Four Real Bugs and What They Cost
  A merge script that copied zero documents, a service worker serving yesterday's site, Bing returning decoy results, and a video player nobody could open — four real bugs from this project, written up while the scars are fresh.
• Tor Onion Services for Websites: Hiding Your Server in Plain Sight
  An onion service lets visitors reach your website through the Tor network without your server exposing any IP address — a practical alternative when domains get blocked.
• The Science of Cooking — Heat, Salt, Fat and Water
  Every recipe ever written is applied physics with a taste test. Four forces — heat, salt, fat and water — do almost all the work in a kitchen, and once you can name them, instructions stop being arbitrary and start being obvious. Here is the model behind good cooking.
• Testing Your Node.js App Without Ceremony
  You do not need a testing framework religion to know whether your code works — start with a script, a few assertions, and one command you run before every deploy.
• Scaling a Search Index from 25 to 32,000 Documents in One Evening
  Our primary index quietly held two dozen pages while a forgotten test index held 32,000 — the fix was a merge script, but the lesson was about index discipline.
• RSS Feeds Are Still the Best Way to Build a News Tab
  Before ranking news, you have to ingest it — and plain RSS over HTTPS remains the fastest, most honest pipeline from publisher to search results.
• Reverse Proxies and the Death of "Real" Client IPs
  Behind a proxy, CDN, or tunnel, `socket.remoteAddress` is the proxy — not the visitor. Everything from rate limits to geo to abuse reports goes wrong until you read the right header, and validate it.
• Rate Limiting and Basic Abuse Protection for Small Web Apps
  One `express-rate-limit` rule and a couple of sensible timeouts stand between your hobby server and a script that bills you for bandwidth you never used.
• The Places You Cannot Drive To — Islands, Isthmuses and the Road Network's Seams
  Ask a route planner to drive from Kuching to Kuala Lumpur and it fails honestly: no road exists between Borneo and the peninsula. Geography is full of these seams — here is why some trips need a ferry, a plane, or a 2,000-kilometre detour.
• Percentages, Ratios and Discounts: The Mental Maths of Everyday Life
  Discounts, tax, tips, interest, statistics — it is all the same handful of percentage tricks. Master a few conversions and you will never again be fooled by a "20% then 10% off" sale or a "50% more" label.

• How to Learn Anything for Free Online — Without Enrolling in a Course
  You do not need a certificate or a subscription to learn physics, coding, or history. The hard part is not access, it is structure. Here is a repeatable method for self-teaching using free references, and how to keep from wandering.
• Landlocked Countries — The High Price of Living Without a Coast
  Forty-plus nations conduct all their trade through somebody else's ports, roads and customs. It is one of geography's steepest handicaps — measurable in GDP, freight bills and diplomacy — and the reasons Bolivia still wants a sea outlet explain why maps matter more than treaties.
• Silent Failure: How Our Backup Turned Out to Have Never Succeeded
  For months the snapshot system was confident it had "finished" while every upload to R2 failed silently. The cause: an API token with the wrong scope, and a script that never counted failures. The lesson: timer success is not proof of job success.
• Inline Video Player Embeds: Keeping Visitors on Your Site
  Clicking a video should open a modal on your own domain, not a new tab on someone else's — here is the small amount of JavaScript that makes that work.
• IndexNow: Submitting URLs to Bing (and Friends) the Moment They Publish

• How Turn-by-Turn Navigation Works — From Map Data to "Turn Left in 200 Metres"
  Every route you have ever followed came from the same pipeline: a giant graph of roads, a search for the cheapest path through it, and a translation layer that turns geometry into human instructions. Here is each step, in plain language.
• How the Water Cycle Works: Evaporation, Condensation and Precipitation
  Earth has a fixed supply of water that has been recycled for billions of years. The water cycle is how solar energy moves that water between oceans, air and land — and why the glass you drink from has probably passed through a cloud, a river and an ocean more times than you can count.

  Every time a charger fits, a shipping container lifts onto any crane, or an email crosses an ocean, an agreement nobody signed wins. Standards are the hidden layer of civilisation — slow, boring, committee-ridden, and the reason the modern world clicks together at all.
• How Ancient Books Survived the Centuries
  Almost nothing written before 500 BC was meant to last, and yet we read it. The survival of ancient texts is not a happy default — it is a chain of accidents, copyists, burnings and one machine that changed everything. Here is the journey from papyrus roll to your screen.
• Famous Software Bugs That Changed Engineering Forever
  Ariane 5 exploded, Therac-25 killed, and a decimal point cost a bank $330M — the canonical bug stories are not gossip, they are the curriculum nobody teaches formally.
• Earth's Magnetic Field: How a Churning Core Shields the Surface
  A compass points north because the outer core is a molten iron dynamo in motion — and that same invisible field deflects the solar wind that would otherwise strip our atmosphere. Here is how it works, why magnetic north keeps wandering, and what a reversal would actually do.
• DNS over HTTPS (DoH): When Your Resolver Starts Lying
  DNS over HTTPS encrypts domain lookups inside a normal HTTPS connection, which makes DNS poisoning and filtering far harder for anyone sitting between you and the truth.
• Coral Reefs: The Animal Cities That Build the Shallow Ocean
  Reefs cover less than one per cent of the seabed and host about a quarter of all marine species — built by a small animal in partnership with a single-celled farmer. Here is the biology of the structure, the arithmetic of bleaching, and why the 2023–2024 event was the largest on record.
• Comets: How Icy Visitors Build Their Tails, and When You Can See One
