Obfuscation and its remedies
He “took every step that he could to try to obfuscate, to try to get people to lie, tried to reward those people who refused to cooperate with a legitimate investigation, tried to punish and denigrate the people who were cooperative” (The Hill). That’s how the former Watergate special prosecutor (Richard Ben-Veniste) summarised the Mueller … 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
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
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
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
How smart are smart contracts?
Blockchain technologies such as bitcoin, support peer-to-peer monetary transactions, where lines in a shared ledger indicate payer, payee, date, amount and the goods or services to be exchanged: as is the case in a line in a bank statement. But, instead of a text line indicating the product being exchanged, what if that line included … Continue reading
Sign here ……………………
How do signatures function? A signature is a sign, seal, or mark on a document indicating its authenticity, as when a painter signs a painting, or someone signs a letter or legal document. The signature and the thing it marks is meant to be a one-off. The signature marks an original document, before the thing … Continue reading
Decode this
Political statements come coded: “I think there’s blame on both sides. I don’t have any doubt about it and you don’t have any doubt about it either.” That was Trump on the white supremacist contingent at the Unite the Right demonstration in Charlottesville this week (with violence resulting in deaths and injury). The statement sounds … Continue reading
An anti-hacker puzzle
Following on from my previous post … Here’s a simple puzzle challenge. The SHA256 hashing algorithm (see earlier post: Immutable data) converts any string of text (integers or letters) into a (near) unique 64 character long string of numbers and letters. Using this algorithm the string “301253” (someone’s birthdate) translates to the string of characters … Continue reading
