Computers Are Bad is a newsletter on the history of the computer
and communications industry. It will be thrown directly at your doorstep on
semi-regular schedule, to enlighten you as to why computers are that
way.
I have an MS in information security, several certifications, and ready
access to a keyboard. These are all properties which make me ostensibly
qualified to comment on issues of computer technology. I do my best to stay
away from my areas of professional qualification, though. Instead, I talk
about things that are actually interesting. Think mid-century
telecommunications history, legacies of the Cold War, and the rise and fall
of the technology industry's stranger bit players.
You can read here, on the information superhighway, but to keep your
neighborhood paperboy pedaling down that superhighway on a bicycle please subscribe. This also contributes
enormously to my personal self esteem. There is an RSS feed for those who really want it. Fax
delivery available upon request.
Last but not least, consider supporting me on Ko-Fi. Monthly
supporters receive eyes only, a special bonus
edition that is lower effort and higher sass, covering topics that don't
quite make it to a full article.
The way I see it, few parts of American life are as quintessentially American
as buying gas. We love our cars, we love our oil, and an industry about as old
as automobiles themselves has developed a highly consistent, fully automated,
and fairly user friendly system for filling the former with the latter.
I grew up in Oregon. While these rules have since been relaxed, many know
Oregon for its long identity as one of two states where you cannot pump
your own gas (the other being New Jersey). Instead, an attendant, employee
of the gas station, operates the equipment. Like Portland's lingering indoor
gas station, Oregon's favor for "full-service" is a holdover. It makes sense,
of course, that all gas stations used to be full-service.
The front part of a gas station, where the pumps are and where you pull up your
car, is called the Forecourt. The practicalities of selling gasoline, namely
that it is a liquid sold by volume, make the forecourt more complex than you
might realize. It's a set of devices that many of us interact with on a regular
basis, but we rarely think about the sheer number of moving parts and
long-running need for digital communications. Hey, that latter part sounds
interesting, doesn't it?
Electric vehicles are catching on in the US. My personal taste in vehicles
tends towards "old" and "cheap," but EVs have been on the market for long
enough that they now come in that variety. Since my daily driver is an EV,
I don't pay my dues at the Circle K nearly as often as I used to. One
of the odd little details of EVs is the complexity hidden in the charging
system or "EVSE," which requires digital communications with the vehicle
for protection reasons. As consumers across the country install EVSE in
their garages, we're all getting more familiar with these devices and their
price tags. We might forget that, well, handling a fluid takes a lot of
equipment as well... we just don't think about it, having shifted the whole
problem to a large industry of loosely supervised hazardous chemical
handling facilities.
The front of the American grocery store contains a strange, liminal space: the
transitional area between parking lot and checkstand, along the front exterior
and interior of the building, that fills with oddball commodities. Ice is a
fixture at nearly every store, filtered water at most, firewood at some. This
retail purgatory, both too early and too late in the shopping journey for
impulse purchases, is mostly good only for items people know they will need as
they check out. One of the standard residents of this space has always struck
me as peculiar: dry ice.
Carbon dioxide ice is said to have been invented, or we might better say
discovered, in the 1830s. For whatever reason, it took just about a hundred
years for the substance to be commercialized. Thomas B. Slate was a son of
Oregon, somehow ended up in Boston, and then realized that the solid form of
CO2 was both fairly easy to produce and useful as a form of refrigeration.
With an eye towards marketing, he coined the name Dry Ice—and founded the
DryIce Corporation of America. The year was 1925, and word quickly spread.
In a widely syndicated 1930 article, "Use of Carbon Dioxide as Ice Said to
be Developing Rapidly," the Alamogordo Daily News and others reported that
"the development of... 'concentrated essence of frigidity' for use as a
refrigerant in transportation of perishable products, is already taxing the
manufacturing facilities of the Nation... So rapidly has the use of this new
form of refrigeration come into acceptance that there is not sufficient
carbon dioxide gas available."
The rush to dry ice seems strange today, but we must consider the refrigeration
technology of the time. Refrigerated transportation first emerged in the US
during the middle of the 19th century. Train boxcars, packed thoroughly with
ice, carried meat and fruit from midwestern agriculture to major cities.
This type of refrigerated transportation greatly expanded the availability
of perishables, and the ability to ship fruits and vegetables between
growing regions made it possible, for the first time, to get some fresh
fruit out of season. Still, it was an expensive proposition: railroads built
extensive infrastructure to support the movement of trains loaded down with
hundreds of tons of ice. The itself had to be quarried from frozen lakes,
some of them purpose-built, a whole secondary seasonal transportation
economy.
Previously on Computers Are Bad, we discussed the early history of air
traffic control in the United States.
The technical demands of air traffic control are well known in computer history
circles because of the prominence of SAGE, but what's less well known is that
SAGE itself was not an air traffic control system at all. SAGE was an air defense
system, designed for the military with a specific task of ground-controlled
interception (GCI). There is natural overlap between air defense and air
traffic control: for example, both applications require correlating aircraft
identities with radar targets. This commonality lead the Federal Aviation Agency
(precursor to today's FAA) to launch a joint project with the Air Force to
adapt SAGE for civilian ATC.
There are also significant differences. In general, SAGE did not provide any
safety functions. It did not monitor altitude reservations for uniqueness,
it did not detect loss of separation, and it did not integrate instrument
procedure or terminal information. SAGE would need to gain these features to
meet FAA requirements, particularly given the mid-century focus on
mid-air collisions (a growing problem, with increasing air traffic, that SAGE
did nothing to address).
The result was a 1959 initiative called SATIN, for SAGE Air Traffic Integration.
Around the same time, the Air Force had been working on a broader enhancement
program for SAGE known as the Super Combat Center (SCC). The SCC program was
several different ideas grouped together: a newer transistorized computer to
host SAGE, improved communications capabilities, and the relocation of Air
Defense Direction Centers from conspicuous and vulnerable "SAGE Blockhouses"
to hardened underground command centers, specified as an impressive 200 PSI
blast overpressure resistance (for comparison, the hardened telecommunication
facilities of the Cold War were mostly specified for 6 or 10 PSI).
Some years ago, I had a frustrating and largely fruitless encounter with the
politics of policing. As a member of an oversight commission, I was
particularly interested in the regulation of urban surveillance. The Albuquerque
Police Department, for reasons good and bad, has often been an early adopter
of surveillance technology. APD deployed automated license plate readers,
mounted on patrol cars and portable trailers, in 2013. Initially, the department
kept a six-month history of license plate data. For six months, police could
retrospectively search the database to reconstruct a vehicle, or person's,
movements—at least, those movements that happened near select patrol cars and
"your speed is" trailers. Lobbying by the American Civil Liberties Union and
public pressure on APD and city council lead to a policy change to retain data
for only 14 days, a privacy-preserving measure that the ACLU lauded as one of
the best ALPR policies in the nation.
Today, ALPR is far more common in Albuquerque. Lowering costs and a continuing
appetite for solving social problems with surveillance technology means that
some parts of the city have ALPR installed at every signalized
intersection—every person's movements cataloged at a resolution of four
blocks. The data is retained for a full year. Some of it is offered, as a
service, to law enforcement agencies across the country.
One of the most frustrating parts of the mass surveillance debate is the ability
of law enforcement agencies and municipal governments to advance wide-scale
monitoring programs, weather the controversy, and then ratchet up retention and
sharing after public attention fades. For years, expansive ALPR programs spread
through most American cities with little objection. In my part of the country,
it seemed that the controversy over ALPR had been completely forgotten until
one particularly significant ALPR vendor—Flock Safety—started repeatedly
stepping in long-festering controversies with such wild abandon that they are
clearly either idiots or entirely unconcerned about public perception.
One of the difficult things about describing a grift, or at least what became
a grift, is judging the sincerity with which the whole thing started. Scams
often crystallize around a kernel of truth: genuinely good intentions that
start rolling down the hill to profitability and end up crashing through every
solid object along the way. I'm not totally sure about Evelyn Wood; she seems
to have had all the best in mind but still turned so quickly to hotel conference
room seminars that I have trouble lending her the benefit of the doubt.
Still, she was a teacher, and I am inclined to be sympathetic to teachers. Funny,
then, that Wood's journey to fame started with another teacher. His curious
reading behavior, whether interpreted as intense attention or half-assed inattention,
set into motion one of the mid-century's greatest and, perhaps, most embarrassing
executive self-help sensations.
In 1929, Evelyn Wood earned a bachelor's in English at the University of Utah.
The following two decades are a bit obscure; she took various
high-school jobs around Utah leading ultimately to Salt Lake City's Jordan
High School. There, as a counselor to girl students, Wood found that many
students struggled because of their reading. Assigned books were arduous,
handouts discarded. These students struggled to read so severely that it
hampered their performance in every area. She launched a remedial reading
program of her own design, during which she made her first discovery: as
her students learned to read faster, their comprehension improved. Then
their grades—in every subject—followed suit. Reading, she learned, was a
foundational skill. A person could learn more, do more, achieve more, if
only they could read faster.
Wood became fascinated with reading, probably the reason for her return to
the University of Utah for a master's degree in speech. Around 1946, she turned
her thesis in to Dr. Lowell Lees. Lees was the chair of the Speech and
Theater Department, and had a hand in much of the development of Utah theater
from the Great Depression until his death in the 1950s. A period photo of Lees
depicts him with a breastplate-microphone intercom headset and a look of
concentration, hands on the levers of a mechanical variac dimmer rack. He is
backstage of either "Show Boat" or "A Midsummer Night's Dream" at the
university's summer theater festival. A theater department chair on lights
seems odd, yes, but theater was Lees passion.
