A team ported the original 1993 Doom engine to run entirely inside SQL queries — every frame rendered through joins, every demon spawned via SELECT statements. It’s a glorious exercise in unnecessary engineering that reveals just how far modern database query optimizers have come: the engine can push enough tuples per second to produce playable, if chunky, first-person gameplay. The piece doubles as a surprisingly lucid explanation of how modern SQL databases execute queries under the hood, using absurdity as a teaching tool.

The Luddites weren’t simply anti-technology — they were skilled textile workers whose jobs and livelihoods were being deliberately deskilled by factory owners who broke long-standing labor agreements. This deep dive into the real history of the Luddite movement recovers what the popular imagination has sanded off: the Luddites had concrete grievances, organized resistance, and suffered state violence. It’s a timely historical corrective as AI automation debates heat up, and a reminder that techno-skepticism has a much richer, more specific tradition than the caricature suggests.

Fresh analysis of First Dynasty Egyptian mass burials has found blunt-force trauma on 39 percent of skulls examined — strong forensic evidence that attendants and retainers were killed to accompany their rulers into the afterlife. The finding revives a debate that has simmered for decades: were these mass graves evidence of ritual sacrifice, or could they represent war casualties or plague? The detailed osteological work here shows how modern forensic methods can squeeze new information from centuries-old bones, turning a settled question back into an open one.

A backpacker completed the entire Appalachian Trail on a two-thousand-dollar budget and lived to tell the tale — with some surprising conclusions about what gear actually matters. The interview covers her unconventional choices (hiking pants declared pointless, expensive gear replaced with creative substitutes) and the economics of long-distance hiking for someone who isn’t sponsored or wealthy. It’s a practical counter-narrative to the gear-heavy culture of modern backpacking, and a genuine how-to for anyone wondering what a thru-hike actually costs at the low end.

A 250-mile traverse of the Japan Alps from the Sea of Japan to the Pacific, crossing one of the most densely populated mountain ranges on Earth. The route connects remote onsen towns, ancient pilgrimage routes, and alpine ridges that see far fewer foreign hikers than the better-known Kumano Kodo or Shikoku pilgrimages. Part one of the series sets up the logistics — permits, resupply strategy, navigation through a country where trail signage is in Japanese — and captures the particular flavor of Japanese long-distance hiking, where convenience stores and temple lodgings intersect with serious alpine terrain.

A compact zine of one-liners from data visualization practitioners — quick, memorable heuristics that encode years of chart-making experience. Things like “if you need a pie chart you need a bar chart” and “three colors max unless the data demands otherwise.” It’s the kind of reference that works both as a teaching tool for newcomers and a gut-check for experienced designers. The format itself is notable: a printed zine in an era of bloated data-viz guides, proving that constraints can sharpen advice.

The annual 30 Day Map Challenge is approaching — thirty daily map-making prompts running through November, pushing participants to explore new datasets, tools, and cartographic styles. This prep post rounds up resources, data sources, and inspiration for anyone considering taking part, from first-timers to seasoned GIS professionals. The challenge has grown into one of the cartography community’s most creative rituals, producing everything from stunning static print maps to interactive web experiments, and the sheer diversity of approaches makes it a yearly highlight for anyone who cares about spatial thinking.

The mathematical foundation of JPEG compression — the discrete cosine transform — was rejected for funding in 1972 by a reviewer who called it too mathematically trivial to be worth supporting. Today, every digital camera, smartphone, and web browser on Earth runs that same math billions of times per day. It is one of those rare stories where a single peer-review decision nearly altered the technical trajectory of consumer computing, and a perfect illustration that the value of an idea is rarely obvious at the moment of its evaluation.

An 1809 cipher written by Napoleon’s nephew has been broken — by AI. The piece, from security expert Bruce Schneier, places the decryption in the context of a broader trend: machine learning is increasingly effective at cracking historical ciphers that have resisted traditional cryptanalysis. Each new success raises questions about what historical documents might still yield secrets, and whether any analog encryption is safe from modern pattern-matching approaches. The letter itself offers a small window into Napoleonic-era military communication.

A look at the Victorian-era photographic genre known as the ‘hidden mother’ — portraits of infants and young children where the mother (or another adult) was physically present to hold the child still but draped in fabric, hidden behind furniture, or otherwise disguised to appear absent. The long exposures required for early photography made this necessary, but the resulting images are eerie, tender, and sometimes unintentionally surreal. The piece probes the intersection of technology’s limitations, maternal labor, and the performative nature of family photography — conventions that persist in different forms today.
