> EASYCHAIR – also written as Easy Chair or EC – was the codename of a super secret research project, initiated by the US Central Intelligence Agency (CIA), aiming to develop covert listening devices (bugs) based on the principle of the Resonant Cavity Microphone – also known as The Great Seal Bug or The Thing – that had been found in 1952 in the study of the US ambassador’s residency in Moscow, hidden in a donated wooden carving of the Great Seal of the United States.

> Upon discovery of The Thing, many US agencies – including the CIA – investigated the possibility of using the new – hitherto unknown – technology to its own advantage. The secret research took place in the Netherlands at the Dutch Radar Laboratory (NRP) in Noordwijk.

I’ve found an incredible diversity, even though they have fairly consistent goals. This post is an attempt to find common patterns, to characterize the design space as a whole. It will be rough, at some points almost a stream of consciousness. If I had the time and energy, I think it could be expanded into an academic paper. But, for now, perhaps these rough thoughts are interesting to some people working in the space.

> A few years ago, Mustapha Harb realized there was a problem in his field of research about how autonomous cars will change the way people travel. The solution to the problem he settled on was as simple as it was revealing.

> Using 13 volunteers (a very small sample size due to budgetary constraints) from the San Francisco Bay Area who owned cars, Harb and his team studied their travel patterns using GPS trackers on their cars and phones for one week, then gave them a chauffeur for a week who would drive the participants’ personal vehicles for them. Finally, the researchers observed the subjects for a final week to look for any changes returning to their chauffeur-less life.

> It went to a national security adviser, Zbigniew Brzezinski, who was awakened on 9 November 1979, to be told that the North American Aerospace Defense Command (NORAD), the combined U.S.–Canada military command–was reporting a Soviet missile attack. Just before Brzezinski was about to call President Carter, the NORAD warning turned out to be a false alarm. It was one of those moments in Cold War history when top officials believed they were facing the ultimate threat. The apparent cause? The routine testing of an overworked computer system.

> All over the world, in Dutch clubs like the one Kok frequented, or Australian biker hangouts and Mexican drug safe houses, there is an underground trade of custom-engineered phones. These phones typically run software for sending encrypted emails or messages, and use their own server infrastructure for routing communications.

> For MPC, the process of setting up the devices was relatively simple: MPC would take a Google Nexus 5 or Nexus 5X Android phone, and then add its own security features and operating system, according to social media posts from MPC and a source with knowledge of the process. MPC then created the customer’s messaging accounts, added a data-only SIM card (which MPC paid about £20 a month for), and then sold the phone to the customer at £1,200. Six-month renewals cost £700, the source added. MPC only sold around 5,000 phones, the source said, but that still indicates the business netted the company some £6 million. At one point, a version of MPC’s phones also used code from an open-source, security-focused Android fork called CopperheadOS, three sources said.

Less well publicized, however, are the various ways in which Shaw has applied his fund’s risk-averse, quantitative approach to nearly every aspect of his life. Employees tell stories about Shaw wanting Chinese food or a comfortable mattress, and Shaw staff exhaustively researching and testing the options in advance. It was company lore that before Shaw traveled, an assistant would take the exact same trip — same car service, same airport, same seat on the plane — to eliminate any inefficiencies. Shaw has been said to purchase tickets for several different flights on the same day in case his plans change.

How similar is one set of beliefs to another? I’ve had informal versions of these ideas since I was a young child, but information theory crystallizes them into precise, powerful ideas. These ideas have an enormous variety of applications, from the compression of data, to quantum physics, to machine learning, and vast fields in between.

> There is a commonly held belief that Helvetica is the signage typeface of the New York City subway system, a belief reinforced by Helvetica, Gary Hustwit’s popular 2007 documentary about the typeface. But it is not true—or rather, it is only somewhat true. Helvetica is the official typeface of the MTA today, but it was not the typeface specified by Unimark International when it created a new signage system at the end of the 1960s. Why was Helvetica not chosen originally? What was chosen in its place? Why is Helvetica used now, and when did the changeover occur? To answer those questions this essay explores several important histories: of the New York City subway system, transportation signage in the 1960s, Unimark International and, of course, Helvetica. These four strands are woven together, over nine pages, to tell a story that ultimately transcends the simple issue of Helvetica and the subway.

> In the early 1970s, a momentous series of events in the history of science unfolded at points around the San Francisco Bay. Lines of inquiry pursued at the Stanford University School of Medicine and the University of California, San Francisco converged on a set of discoveries that vastly expanded the productive capabilities of molecular genetics, disrupted the customary rhythms and routines of the scientific community, sparked bitter disputes about risks and responsibilities in scientific experimentation, and generated a tsunami of technological change that spread rapidly across multiple domains of productive activity and all around the globe.

> The first recombinant molecule containing DNA from different organisms was assembled late in 1971, in Paul Berg’s laboratory at Stanford. Berg hoped to transduce bacterial and mammalian cells with a recombinant virus in order to study gene expression systems, but subsequently chose not to carry out the planned experiments. He was persuaded by scientific colleagues to consider potential biohazard risks before moving ahead.

> The technology for propagating and expressing recombinant genes was invented by Stanley Cohen and Herbert Boyer in 1973. It enabled the transformation of bacterial cells into living factories for the directed manufacture of select proteins. The technology was immediately recognized as a tool without parallel in genetics research, and was soon applied to practical ends in a wide variety of fields including medicine, pharmaceuticals, agriculture, chemicals, and energy. It has since transformed the world in which we live.

> The string that contains one graphical unit consists of 5 Unicode scalar values. First, there’s a base character that means a person face palming. By default, the person would have a cartoonish yellow color. The next character is an emoji skintone modifier the changes the color of the person’s skin (and, in practice, also the color of the person’s hair). By default, the gender of the person is undefined, and e.g. Apple defaults to what they consider a male appearance and e.g. Google defaults to what they consider a female appearance. The next two scalar values pick a male-typical appearance specifically regardless of font and vendor. Instead of being an emoji-specific modifier like the skin tone, the gender specification uses an emoji-predating gender symbol (MALE SIGN) explicitly ligated using the ZERO WIDTH JOINER with the (skin-toned) face-palming person. (Whether it is a good or a bad idea that the skin tone and gender specifications use different mechanisms is out of the scope of this post.) Finally, VARIATION SELECTOR-16 makes it explicit that we want a multicolor emoji rendering instead of a monochrome dingbat rendering.

And then we move on from there, in quite some depth.

> In 1994, Cesare Marchetti, an Italian physicist, described an idea that has come to be known as the Marchetti Constant. In general, he declared, people have always been willing to commute for about a half-hour, one way, from their homes each day. This principle has profound implications for urban life. The value of land is governed by its accessibility—which is to say, by the reasonable speed of transport to reach it.

> But the endurance of the Marchetti Constant has profound implications for urban life. It means that the average speed of our transportation technologies does more than anything to shape the physical structure of our cities. To see how, let’s travel back in time by more than 2,000 years, and move towards the present.
