City cops in Disneyland’s backyard have had “stingray on steroids” for years
Pentagon: DRTBox can usually nab phone’s crypto session keys in under a second.
New documents released (PDF) on Wednesday by the American Civil Liberties Union (ACLU) of California show that for the last several years, police in the city of Anaheim, California—home of Disneyland—have been using an invasive cell phone surveillance device, known as a "dirtbox."
The ACLU obtained the 464 pages of documents recently after it sued the Anaheim Police Department (APD) last year over the agency’s failure to respond to its public records request concerning such surveillance-related documents.
The DRTBox has been described by one Chicago privacy activist as a "stingray on steroids," referring to the controversial cell-site simulator that spoofs cell towers to locate phones and intercept calls and texts.

Apollo 1, Challenger, and Columbia: Remembering NASA’s lost astronauts
From the archives: NASA’s three worst disasters are clustered at the end of January.
Update: Yesterday, February 1, marked 16 years since the 2003 Columbia disaster. Those both in the space industry and those watching have long realized and acknowledged the inherent risk in reaching the heavens ("The conquest of space is worth the risk of life,” as Gus Grissom once famously said). But events like this provide a somber reminder. In light of three recent days of NASA remembrance—January 27, January 28, and February 1—we're resurfacing our look at these tragedies and the astronauts lost. This post originally ran on January 28, 2016, and it appears unchanged below.
The middle of winter is a somber time of year for the spaceflight community. The three worst tragedies of NASA's manned space program fall within just six days on the calendar, from January 27 to February 1: Apollo 1, less than three years before Armstrong and Aldrin walked on the Moon; Challenger, watched live by millions around the world; Columbia—like Challenger before it, an avoidable accident rooted in NASA's internal culture.

Apollo 1: January 27, 1967
The loss of the Apollo 1 crew (along with the spacecraft) several weeks before its intended launch date was a severe setback for America's lunar ambition. Apollo 1 was supposed to carry Gus Grissom, Ed White, and Roger Chaffee into low Earth orbit on February 21, 1967, the first launch in a series that would culminate in a pair of American astronauts walking on the Moon's surface in July 1969. Instead, all three suffocated when fire broke out in the Command Module during what was thought to be a low-risk test.
Orange Pi One is a tiny quad-core PC for $10 (plus $4 shipping)
When the original Raspberry Pi launched in 2012 it seemed crazy that a fully-functional computer could be priced at just $35… even if it had a relatively slow processor and other anemic specs. These days there’s no shortage of dirt cheap single-board computers. The Raspberry Pi team even sells a new $5 version. But if you’ve […]
