How Etak Built a Car Navigation System In 1985

harrymcc writes: Thirty years ago, a startup called Etak released the Navigator, an in-car navigation system. It provided turn-by-turn driving directions despite the fact that GPS did not exist, and stored its maps–which Etak had to create itself–on cassette tapes. And some of its data and technologies are still in use in today’s navigation apps. Over at Fast Company, Benj Edwards tells this amazing story. I remember reading about (and lusting over) this system back then, in the much-missed DAK catalog. Read more of this story at Slashdot.

New Manufacturing Technique Halves Cost of Lithium-Ion Batteries

An anonymous reader writes: Experts in materials science at MIT have developed a new process for creating lithium-ion batteries that will drop the associated production costs by half. The researchers say fundamental battery construction techniques have been refined over the past two decades, but not re-thought. “The new battery design is a hybrid between flow batteries and conventional solid ones: In this version, while the electrode material does not flow, it is composed of a similar semisolid, colloidal suspension of particles. Chiang and Carter refer to this as a ‘semisolid battery.’ This approach greatly simplifies manufacturing, and also makes batteries that are flexible and resistant to damage, says Chiang. … Instead of the standard method of applying liquid coatings to a roll of backing material, and then having to wait for that material to dry before it can move to the next manufacturing step, the new process keeps the electrode material in a liquid state and requires no drying stage at all. Using fewer, thicker electrodes, the system reduces the conventional battery architecture’s number of distinct layers, as well as the amount of nonfunctional material in the structure, by 80 percent.” Read more of this story at Slashdot.

What Are All Those Weird Noises You Hear on an Airplane?

I used to work at Boeing and repaired the computerized part of the machines which put together 747’s. People not familiar with airplanes are scared because they are forced to be quiet and go along with acting normal while stuck in a tube hurtling through the air at 600 miles an hour, and 30, 000 feet above the earth. What could go wrong? Read more…

Tip of the Day: Don’t Commit a Crime While Wearing a Fitbit

I mean, if you want to get caught committing a crime, please do wear your Fitbit. That’s what a Florida woman learned when she told police she’d been assaulted in March — only to have them examine her Fitbit and discover that the truth was a lot uglier and more awkward. Read more…

NIST Workshop Explores Automated Tattoo Identification

chicksdaddy writes: Security Ledger reports on a recent NIST workshop dedicated to improving the art of automated tattoo identification. It used to be that the only place you’d commonly see tattoos was at your local VA hospital. No more. In the last 30 years, body art has gone mainstream. One in five adults in the U.S. has one. For law enforcement and forensics experts, this is a good thing; tattoos are a great way to identify both perpetrators and their victims. Given the number and variety of tattoos, though, how to describe and catalog them? Clearly this is an area where technology can help, but it’s also one of those “fuzzy” problems that challenges the limits of artificial intelligence. The National Institute of Standards and Technology (NIST) Tattoo Recognition Technology Challenge Workshop challenged industry and academia to work towards developing an automated image-based tattoo matching technology. Participating organizations in the challenge used a FBI -supplied dataset of thousands of images of tattoos from government databases. They were challenged to develop methods for identifying a tattoo in an image, identifying visually similar or related tattoos from different subjects; identifying the same tattoo image from the same subject over time; identifying a small region of interest that is contained in a larger image; and identifying a tattoo from a visually similar image like a sketch or scanned print.

Facebook’s Absurd Pseudonym Purgatory

An anonymous reader sends a story from a writer whose Facebook account was locked because somebody reported it as using a pseudonym. It doesn’t, but Facebook demands a look at identification documents before releasing control over the account. Anyone whose name doesn’t sound “real” to Facebook is at risk for this, and the social network doesn’t even have a consistent stance on what an “authentic” name is. “Aside from the complexity of identity, the policy is haphazardly enforced at best. At worst, it’s dangerous and discriminatory, and has demonstrably and repeatedly been used to target people who often already are marginalized and vulnerable.” Matt Cagle, attorney for the ACLU, says, “By controlling the identity of the speaker with this policy, Facebook has the effect of both reducing speech and eliminating speakers from the platform altogether. This is a particularly concerning move to the ACLU because forums like Facebook serve as the modern-day equivalent of the public square for a lot of communities. Read more of this story at Slashdot.
