Romancing the blockchain

The blockchain idea is addictive for some. It’s technically fascinating, mysterious and counter-intuitive. It depends on cryptography to function, and inherits the fascination many of us have with cyphers and codes. Who can resist the lure of a secret message? The way blockchain platforms function also mystify with their abstruse methods and terminology: proof of … Continue reading

Sociable encryption: The secret of the five keys

Will encryption save us? Social psychologist Shoshana Zuboff explains in detail the methods employed by Google and other digital giants to track our clicks, sell our data, and auction targeted advertising slots to monetise our private on-screen experiences. Our online behaviour is the resource. We are the product, not the consumer. Google’s clients are advertisers … Continue reading

Nested parentheticals

Sometimes it’s hard to get back on track. People tell stories and construct arguments with subplots and digressions. It’s fine for stories to wander. But for coherence we expect the story-teller to return to the main point, to rewind the string they just unravelled back into a neat ball. One of Trump’s improvised speeches illustrates … Continue reading

Architecture and espionage

The Spy Museum near Potsdamer Platz in Berlin features cumbersome cold-war surveillance and bugging devices, and retells the story of spying and secret communications dating back to Ancient Egypt. Architecture is always there as a stage setting for covert operations. After all, spies inhabit the shadows. I recall from previous reading that Odysseus disguised himself … Continue reading

The death of a public life

You can be excused for thinking that social media presents imperfect insights into human nature. US political comedian Bill Maher excoriated the public personas social media users present online — their polite, politically correct, family-friendly, “prissy” avatars, whose great “super power” is that they remember birthdays! “If you want to know who someone really is … Continue reading

Cooperation and complicity

The Barras is a market in Glasgow that is (or was) notorious as a site for hustlers. It attracts both bargain hunters and spectators. Ten years ago a group of us conducted a study of the area, mainly to consider its soundscape. On more than one visit we observed a familiar scenario involving the sale … Continue reading

Challenges of the sharing economy

Architectural Research Quarterly just published an article by Tolu Onabolu and me called “Blockchain for architects: Challenges from the sharing economy.” Our tagline is: “Cryptocurrencies, blockchain technology, and other aspects of the sharing economy offer benefits and challenges for architecture. They also furnish metaphors about urban living.” The article derives from speculations in this blog … Continue reading

What’s wrong with the sharing economy

The so-called sharing economy has come under a lot of criticism lately. Think of the apparently (almost) unregulated and unfair practices surrounding Uber, the global car hire (taxi) firm that designates its drivers as self-employed. Passengers like Uber. Once subscribed, you book a car and driver via your smartphone. You track your nearest available ride … Continue reading

Encrypted city

Urban metaphors are powerful in the world of computing. The reverse is also true. Computing brings metaphors to bear on how we think of cities — as flows of data, networks, circuits, grids and an Internet of things, as if cities are made up of bits, memories (RAM), sensors, actuators, and with communication systems, inputs, … Continue reading

Share city

In his book on the “sharing economy,” Arun Sundararajan maintains that commerce is shifting “away from traditional corporations and toward a crowd of entrepreneurs we find through a digital marketplace” (6). Within the constellation of these new (shared) business models he places Airbnb, a platform that allows individuals to capitalise on their own under-utilised domestic … Continue reading
