When Maps Lie

A map is not just a picture—it’s also the data behind the map, the methodology used to collect and parse that data, the people doing that work, the choices made in terms of visualization and the software used to make them. A map is also a representation of the world, which in some ways must always be a little inaccurate—most maps, after all, show the roughly spherical world on a flat surface. Certain things are always left off or highlighted while others are altered, as no map can show everything at once. All of those choices and biases, conscious or not, can have important effects on the map itself. We may be looking at something inaccurate, misleading, or incorrect without realizing it.

How the NSA searches the world’s intercepted private communications

XKEYSCORE is a secret NSA program that indexes data slurped up from covert fiber-taps, hacked systems, and smartphones, including “full take” data and metadata.

XKEYSCORE has been known since last July, when Glenn Greenwald disclosed its existence in a blockbuster Guardian article.

In a thorough, fascinating followup published in the Intercept, Greenwald and colleagues present a detailed look at the system as it stood in 2013, when it consolidated data from 150 field sites. The service uses your Google cookies and cookies from other services to link your activities across multiple sites and forums, making it possible to search for individual users who use different online identities for different purposes.

In its internal documents, the NSA describes how XKEYSCORE is used to spy on world leaders, including the UN General Secretary Ban Ki-moon, whose briefings prior to a meeting with Barack Obama were intercepted and analyzed.

EFF has noted and protested when authorities deliberately cut off Internet access in times of unrest.  As a restraint on the freedom of expression of those affected, communication blackouts during protests are unconscionable.  But recent research by Anita Gohdes, a postdoctoral researcher at the University of Mannheim, suggests that Internet shutdowns are becoming part of a toolkit for more violent repression.

I need to find a public domain image

Reference question of the day was about finding public domain images. Everyone’s got their go-tos. If I am looking for illustrations or old photos specifically I’ll often use other people’s searches on top of the Internet Archive’s content. Here’s a little how to.

1. Check the Internet Archive Book Images feed on Flickr. What I often do is search (which finds the words that surround the images) and then click straight through to the book (which is always linked in the metadata) and then fish around. For example…
