Tracing Power Lines with the Pylon Appreciation Society
Pylons
Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
A haunting, syncopated music
"Rappers" on the roof of the electrostatic precipitator knock the accumulated dust free, letting it fall into the storage hopper. Each rapper is the size and shape of a baseball bat. Inside is an electromagnet that pulls a steel plunger upward, then allows it to fall again, producing a sharp knock. The rappers are energized at seemingly random intervals, producing a haunting, syncopated music. (The rhythm seemed more modern jazz than rap.)
Safety cut rope axe man
In the first nuclear reactor, constructed by Enrico Fermi in 1942 under the bleachers of the University of Chicago football stadium, the control rods were held up by a manila rope. A man with an axe was told to cut the rope if the reactor got out of hand. This "safety cut rope axe man" is supposedly the origin of the term SCRAM for an emergency shutdown procedure.
Color coding
Telephone wires erupt in a multicolor cascade in a ground-level, pedestal-type splice case on a city street.
Dividing the set of 10 colors into two contrasting groups of 5 allows for exactly 25 combinations with one color from each group; thus, each pair in a bundle can be uniquely colored. A similar color code is applied to the ribbons that bind together all the pairs in a bundle, and to those of the superbundles. The result is highly festive! A specific wire might be identified as the blue-red conductor within the orange-black bundle within the brown-yellow superbundle.
How the Blog Broke the Web
Homepages had a timeless quality
On the early web, there were thousands and thousands more personal homepages than weblogs.
Homepages had a timeless quality, an index of interesting or useful or relevant things about a topic or about a person. You didn’t reload a homepage every day in pursuit of novelty. (That’s what Netscape’s What’s Cool was for!)
Chronological content was in the minority.
When Movable Type ate the blogosphere
Here’s the crux of the problem: When something is easy, people will do more of it.
When you produce your whole site by hand, from HEAD to /BODY, you begin in a world of infinite possibility. You can tailor your content exactly how you like it, and organize it in any way you please. Every design decision you make represents roughly equal work because, heck, you’ve gotta do it by hand either way. Whether it’s reverse chronological entries or a tidy table of contents. You might as well do what you want.
But once you are given a tool that operates effortlessly — but only in a certain way — every choice that deviates from the standard represents a major cost.
Movable Type didn’t just kill off blog customization.
It (and its competitors) actively killed other forms of web production.
Reverse chronology bias
Once you’ve had a taste of effortless updates, it’s awfully hard to back to manual everything.
So they didn’t.
And neither did thousands of their peers. It just simply wasn’t worth it. The inertia was too strong.
The old web, the cool web, the weird web, the hand-organized web… died.
And the damn reverse chronology bias — once called into creation, it hungers eternally — sought its next victim. Myspace. Facebook. Twitter. Instagram. Pinterest, of all things. Today these social publishing tools are beginning to buck reverse chronological sort; they’re introducing algorithm sort, to surface content not by time posted but by popularity, or expected interactions, based on individual and group history. There is even less control than ever before.
There are no more quirky homepages.
There are no more amateur research librarians.
All thanks to a quirky bit of software produced to alleviate the pain of a tiny subset of a very small audience.
That’s not cool at all.
