This piece turns a seemingly simple question — how big is Yemen? — into a masterclass in why cartographic literacy matters. The answer depends entirely on which map projection you use, what you’re measuring (land area, territorial waters, or something else), and who benefits from the answer you pick. It’s a compact, surprising argument about how maps encode political choices rather than neutral facts, delivered through a single country case study that will make you question every area comparison you’ve ever seen.

Ken Shirriff is back with another walk through the silicon archaeology of early Intel coprocessors, this time decoding the 8087's tangent function. The chip didn't use the standard CORDIC algorithm everyone assumes — it implemented a hybrid approach that combined polynomial approximation with a lookup table, optimized for the 80-bit floating-point format. The result is a beautifully concrete look at how hardware engineers solved numerical problems under extreme constraints, and a reminder that the cleverest algorithms are often the ones etched into silicon.

A deep dive into the strange, specific visual history of the milk carton missing-children campaign that defined a generation's grocery-store anxiety. This piece traces where those photographs came from, who took them, how they were selected and printed, and what happened to the families behind them years later. It's as much a story about analog-era photo distribution infrastructure, newspaper partnerships, and the ethics of mass-circulation portraiture as it is about the missing children themselves — a forgotten chapter in the intersection of photography, publishing, and public awareness campaigns.

A volunteer mapping project is mining Ukraine's open court registry to build a public map of detention cases — extracting spatial data from legal text to show where people are being held, what borders they crossed, and what administrative boundaries are being enforced on the ground. It's a powerful example of maps as evidence rather than illustration: turning dry court records into a geographic dataset that makes state action visible, using OSM tools and offline-first design for regions where connectivity can't be assumed. The methodological choices — parsing court text for placenames, validating oblast boundaries against reported locations — are as interesting as the human story the map tells.

A pragmatic breakdown of what 'print quality' really refers to once you get past marketing specs — ink droplet size, color gamut overlap, paper handling physics, and the actual differences between dye and pigment inks at the output stage. It compares two popular photo printers (Epson EcoTank ET-8550 and Canon imagePROGRAF PRO-1100) not by spec sheets but by the real-world choices each forces on a user. For anyone who has ever wondered why a print from the same digital file can look dramatically different on two printers, this explains the engineering underneath.

The Tesla Semi is finally arriving with a claimed 500-mile range, but this piece looks past the truck itself to the much harder problem: charging infrastructure built for class-8 semi trucks, which draw many times the power of passenger EVs and need to charge at depots, not highway fast-charger stalls. The article walks through real power-grid constraints, permitting timelines, and the economics of depot charging — a concrete look at the gap between building a capable vehicle and building the system that makes it useful at scale.

A thru-hiker's account of finishing the Appalachian Trail at Katahdin — the iconic northern terminus that caps a 2,190-mile journey. The story captures the strange emotional deflation that often follows big goals: the mix of exhaustion, relief, and anticlimax that comes when an all-consuming plan finally resolves. It's a well-observed look at the psychology of long-distance hiking and the peculiar gap between the imagined summit moment and the real one.

Most offshore wind turbines face into the wind — it's the standard design. OceanX built one that faces away, putting two rotors on a single floating platform designed to run downwind instead. This piece explains why that counterintuitive choice could solve some of floating wind's biggest problems: lighter tower loads, simpler yaw systems, and better performance in deep water far from shore. It's a systems-engineering story about questioning an industry default and finding real efficiencies in the direction wind meets blade.

MoMA's first-ever exhibition dedicated to information design puts data visualization, wayfinding systems, and public-information graphics into a museum context — treating the subway map and the hurricane cone-of-uncertainty as cultural artifacts worth preserving alongside paintings. The show includes work by climatologists, newspaper graphics desks, and designers who shaped how we visually understand complex systems. It raises a good question: when does functional communication cross over into art, and what do we lose when we stop thinking of information design as a craft?

A reflective essay on the Camino de Santiago that asks what the walk means when you strip away the modern pilgrimage infrastructure — the albergues, the yellow arrows, the credential stamps — and consider the routes that existed before Christianity adopted them. It traces Roman roads, Iron Age trade paths, and older movement patterns that got overlaid by later meaning. A thoughtful meditation on how trails accumulate significance across centuries, and whether the modern pilgrim walks the same path at all or just a palimpsest of it.
