Flamewars, 1839 Style

I’ve heard a lot of people say that the need to have arguments in public and win popular support is an unintended consequence of social networking services. I think that things like Twitter and Facebook make it easier and that they vastly expand the reach of an argument, but that we’ve had that urge to have flamewars long before the internet.

Here’s a data point for my thesis: a placard from 1839 that wouldn’t seem out of place on any online debate, aside from the dated language.

"TO THE PUBLIC: The object of this placard is to inform the Public that Gen. Leigh Read has declined giving me an apology for the insult offered me at St. Mark, on the 5th inst. That he has also refused to me that satisfaction, which as an honorable man, (refusing to apologise,) he was bound to give. I therefore pronounce him a Coward and a Scoundrel. -- WILLIAM TRADEWELL, Tallahassee, Oct. 26, 1839."

Multitasking in the “Mad Men” Era

square root

Here’s a great video from 1963 featuring the great-granddad of today’s web servers and cloud computing systems. It was just posted by Boston’s Computer History Museum titled Solution to Computer Bottlenecks. Filmed in May of that year, it features MIT Science Reporter John Fitch – who has a classic 1960’s announcer’s voice – interviewing MIT computer scientist Fernando J. Corbato, the guy behind Corbato’s Law (“The number of lines of code a programmer can write in a fixed period of time is the same independent of the language used”).

The subject of the film is the then-new approach of timesharing, which Corbato describes as “connecting a large number of consoles to a central computer”, which made the great (and very necessary – it even gets mentioned in Malcolm Gladwell’s book, Outliers) leap from batch to interactive processing possible. Here’s the video; enjoy all the retro-tech goodness:

This may have been really deep nerd stuff back in 1963, but today, it the sort of thing that you might see covered in a grade school class. Even if you’re not a programmer or IT pro, I think you’ll find it entertaining.

Some Gems from the Video

A computer terminal in one’s office isn’t unusual in this day and age, but back in 1963, such a thing must’ve been incredibly super-1337. Here’s the console in Corbato’s office, which he introduces by saying “Here’s one of the consoles we might be using in the future.” Even to the reporter of that era, it looked like an ordinary IBM Selectric typewriter:

The general principles of digital computers haven’t changed much since those days. Corbato describes memory as “a bunch of pigeonholes” that store numbers, some of which function as data, some of which function as instructions.

memory pigeonholes

The concept of a CPU, the program counter stepping through memory and looping already existed in 1963:

He describes the new setup “a set parallel consoles which are not all near the computer in fact, most of them are remote…and let the users use these with a reaction time of a few seconds instead of a few hours.”


He says that eventually they’d like to switch from “typewriter” consoles to "graphic displays”, but at the time there were still some kinks to be worked out.

One of the “elaborate advanced ideas” that he hints at but says is beyond the topic of the film is going beyond hooking up dumb terminals to the mainframe and attaching smaller computers to it as well, such as the DEC PDP-1 and 1620:

advanced elaborate ideas

When discussing the hard disk and its capacity (9 million words), Corbato has to explain to Fitch that it isn’t a big whirling disk on which you store tape, but a platter coated with a magnetic material like tape. This is old hat to us in the 21st century, but at the time, disks weren’t household items:

At the time, disks had been around for about a year. Corbato confesses that there are still some problems with them: they “haven’t figured out how to keep things from getting mixed up”.

And on it goes with ideas that are still in use today: programming languages (“a particular synthetic language which is largely technical, and which is to some extent algebra too”), the organization of different programs in memory at the same time, multitasking with a scheduler that determines which program gets the processor’s attention at the moment, file loading and management by the operating system, the concepts of “brute-force solutions”, context switching (which they can “keep down to 10%”), input validation and even the phrase “it’s a feature”.

The line of Corbato’s that I love most is his prescient statement about usability and demand: “We’ve really made the computer extremely easy to use here. And so it’s very clear that in the long run, we’re going to increase in the need for computer time by a large amount.”

This video is all sorts of old-school awesome. If you’ve got nothing to do on your lunch break, check it out!

The “High-Brow/Low-Brow” Chart

I don’t know when this chart classifying the spectrum of tastes from high-brow to low-brow was created, but the graphic style puts it sometime in the “Mad Men” era of the late 1950s and early 1960s. You can click the chart to see it at full size:

I took a couple of columns from the chart and turned them into an enlarged version, shown below. The columns show “high-brow”, “upper middle-brow”, “lower middle-brow” and “low-brow” tastes in clothes, entertainment and drinks.

Some thoughts on these columns from the chart:

  • I’ve worked at a good number of place where coming to work in a t-shirt and jeans was perfectly acceptable. If you showed up in what the chart calls the “low-brow town outfit” you’d have been asked “Hey, why so dressed up?”
  • The present-day analogue of “Western movies” is most likely “action films”.
  • Beer can be pretty high-brow these days.

Someone needs to recompile this chart for the present day.

Are there any computers available today that come in that particular shade of blue, with matching chair?

The Road to Success

I saw the illustrated map titled The Road to Success on the Strange Maps site and thought that there can’t be a more appropriate day than today, the first day of school, to post it. Enjoy!

If you’re wondering who the “Caruso” in the “Caruso can’t touch you” line is – it’s spoken by one of the people in the Mutual Appreciation Society building, in the lower-right hand corner, just above and to the left of Hotel Know-It-All – it’s Enrico Caruso, an opera tenor who became a star thanks tp his embrace of then-newfangled recording technology, namely the phonograph (a.k.a. gramophone).
