A Man in a Hurry: Claude Shannon’s New York Years - IEEE Spectrum

Of course, information existed before Shannon, just as objects had inertia before Newton. But before Shannon, there was precious little sense of information as an idea, a measurable quantity, an object fitted out for hard science. Before Shannon, information was a telegram, a photograph, a paragraph, a song. After Shannon, information was entirely abstracted into bits. The sender no longer mattered, the intent no longer mattered, the medium no longer mattered, not even the meaning mattered: A phone conversation, a snatch of Morse telegraphy, a page from a detective novel were all brought under a common code. Just as geometers subjected a circle in the sand and the disk of the sun to the same laws, and as physicists subjected the sway of a pendulum and the orbits of the planets to the same laws, Claude Shannon made our world possible by getting at the essence of information.

DiceWARE

This is a wonderful service! Handcrafted artisanal passwords made with a tried and trusted technique:

You roll a die 5 times and write down each number. Then you look up the resulting five-digit number in the Diceware dictionary, which contains a numbered list of short words.

That’s the description from the site’s creator, Mira:

Please keep in mind when ordering that I am a full-time sixth grade student with a lot of homework.

She’s the daughter of Julia Angwin, author of Dragnet Nation.

Is Dark Matter Hiding Aliens?

Here’s a fun cosmic hypothesis on the scale of an Olaf Stapeldon story. There are even implications for data storage:

By storing its essential data in photons, life could give itself a distributed backup system. And it could go further, manipulating new photons emitted by stars to dictate how they interact with matter. Fronts of electromagnetic radiation could be reaching across the cosmos to set in motion chains of interstellar or planetary chemistry with exquisite timing, exploiting wave interference and excitation energies in atoms and molecules.

Dark Archives in Contents Magazine

A really lovely piece on the repositories of information that aren’t catalogued—a fourth quadrant in the Rumsfeldian taxonomy, these dark archives are the unknown knowns.
