Patch Notes

Wade follows horror games from Atari’s dark Haunted House through Alone in the Dark, Resident Evil, Silent Hill, Amnesia, and Five Nights at Freddy’s. The real story is how limited hardware, fixed cameras, sound, scarce resources, and eventually streaming culture turned a few pixels into unforgettable scares.

In part 2 of the Patch Notes cell phone series, Wade Mercer explores how cells, antennas, radio channels, backhaul and handovers work, connecting the history and engineering to the technology in your pocket.

In part 1 of the Patch Notes cell phone series, Wade Mercer explores origins of mobile telephony and the first handheld call, connecting the history and engineering to the technology in your pocket.

This Sunday, America is doing something truly impressive. We're going to experience the same hour twice. Not because somebody invented a time machine, but because we invented daylight saving time. And computers, alarm clocks, and people who work the night shift get to deal with the consequences. Welcome to Patch Notes: Unintended Consequences.

A firefly missing from scientific records since nineteen eighty-three has been found again, and a new correction reveals two independent sightings in Virginia and Delaware. Wade Mercer explores the beetle’s remarkable blinking signal, the science of rediscovery, and why careful fieldwork still matters. A genuinely hopeful Hotfix with a few very small lights.

A pack of chewing gum changed the world in nineteen seventy-four.

That was the first product scanned at a supermarket checkout using the Universal Product Code, launching a technology that would transform retail, inventory management, and global supply chains.

But the barcode's story actually began decades earlier, with an unusual idea inspired by Morse code.

Wade Mercer traces the technology from its experimental beginnings through laser scanners, global product identifiers, QR codes, and the retail industry's ongoing transition toward two-dimensional barcodes.

Along the way, we discover why the barcode doesn't contain a product's price, how QR codes survive damage, and why the year twenty twenty-seven matters.

Scientists have created an unusual robotic material that can organize its own movement without a central controller.

Published in Nature on October fourteenth, the research demonstrates how individually vibrating components can gradually synchronize into a stable collective rhythm. The researchers describe the resulting state as a time crystal.

Wade Mercer explores the engineering behind the discovery, why the material behaves differently from ordinary mechanical systems, what time crystals actually are, and how the research could eventually contribute to robots that move and change shape more like living organisms.

What happens when a cyberattack doesn't just steal information, but leaves a bank unable to operate?

Bank of England Deputy Governor Sarah Breeden has warned that financial institutions must prepare for attacks that defeat conventional defenses and potentially compromise critical infrastructure.

Wade Mercer examines the engineering behind modern banking, the dangers of interconnected financial systems, and why recovering from a catastrophic cyberattack involves far more than restoring yesterday's backup.

From bare-metal recovery to artificial intelligence-enabled threats, this episode explores what it really takes to keep our money accessible when the technology behind it fails.

China has proposed sweeping new restrictions on the export of advanced artificial intelligence technologies, including large models, AI agents, and computing infrastructure.

But there's a twist: using an AI service over the internet isn't necessarily the same as transferring the technology behind it.

Wade Mercer breaks down what China announced, why model weights have become strategically important, how export controls could reshape the AI industry, and what this means for developers, businesses, and the future of open technology.

The twenty twenty-six Nobel Prize in Physics has been awarded to Francis Halzen for his decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos from space. Here’s how scientists turned Antarctic ice into a telescope and opened an entirely new way of observing the universe.
