Crime

It looks like the long and winding road of the John McAfee saga is going to continue for at least a little longer. McAfee posted a detailed blog post about how he was able to elude Belizean authorities and sneak out of the country. From the article: “‘It’s visually interesting and it is mostly a happy story — in line with most Christmas stories,’ he wrote. The former software executive describes an operation that was heavy in advance planning and trickery. He says he planted a lookalike (“my double — a man I have known for over 30 years and who years ago legally changed his name to John McAfee”) and had him picked up by authorities in the northern Belize-Mexico border, while he and a group of friends and reporters loaded up a truck and headed in the opposite direction, to a southern town called Punta Gorda. With the news that he’d been arrested broadcasting on a local news station, McAfee figured that checkpoint security would relax.”

The Science of Roadkill

Earth

Hugh Pickens writes “Sarah Harris writes that roadkill may not be glamorous, but wildlife ecologist Danielle Garneau says dead critters carry lots of valuable information providing an opportunity to learn about wildlife and pinpoint migratory patterns, invasive species, and predatory patterns. ‘We’re looking at a fine scale at patterns of animal movement — maybe we can pick up migratory patterns, maybe we can see a phenology change,’ says Garneau. ‘And also, in the long term, if many of these animals are threatened or they’re in a decline, the hope would be that we could share this information with people who could make changes.’ Garneau turns students out into the world to find dead animals, document them and collect the data using a smartphone app RoadkillGarneau and she has already received data from across New York, as well as Vermont, Pennsylvania, Massachusetts, Michigan, Minnesota, Florida and Colorado. Participants take photos of the road kill, and the app uploads them through EpiCollect, which pinpoints the find on the map. Participants can then update the data to include any descriptors of the animal such as its species; sex; how long the dead animal had been there; if and when it was removed; the weather conditions; and any predators around it. ‘People talk a lot about technology cutting us off from nature,’ says Garneau. ‘But I found that with the road kill project, it’s the opposite. You really engage with the world around you — even if it is a smelly skunk decaying on the side of the road.’”

Glow-In-The-Dark Smart Highways Coming To the Netherlands In 2013

October 30th, 2012 10:59 admin View Comments

Transportation

An anonymous reader writes “The Netherlands is moving forward with plans to build ‘smart’ highways that can become more easily visible in the dark or communicate weather conditions to drivers. Work will begin as early as next year. ‘Special paint will also be used to paint markers like snowflakes across the road’s surface — when temperatures fall to a certain point, these images will become visible, indicating that the surface will likely be slippery. Roosegaarde says this technology has been around for years, on things like baby food — the studio has just up-scaled it. The first few hundred meters of glow in the dark, weather-indicating road will be installed in the province of Brabant in mid-2013, followed by priority induction lanes for electric vehicles, interactive lights that switch on as cars pass and wind-powered lights within the next five years.’”

Making Driverless Cars Safer

AI

colinneagle writes “Several autonomous cars have been developed elsewhere, most famously by Google, and they are generally capable of identifying objects in the road directly ahead of or behind them. The challenge undertaken by MIT researchers is making these cars aware of dangers lurking around corners and behind buildings. MIT PhD student Swarun Kumar showed a video of a test run by the MIT researchers in which an autonomous golf cart running the technology, called CarSpeak (PDF), encountered a pedestrian walking from the entrance of a building to a crosswalk. The golf cart stopped roughly five yards ahead of the crosswalk and waited long enough for the pedestrian to walk to the other side of the road. The vehicle then continued driving automatically. The solution Kumar presented is based on a method of communications that is intended to expand the vehicle’s field of view. This can be accomplished by compressing and sharing the data that autonomous vehicles generate while they’re in motion, which Kumar says can amount to gigabits per second. In a comparison test, a car using CarSpeak’s MAC-based communications was able to stop with a maximum average delay of 0.45 seconds, compared to the minimum average delay time of 2.14 seconds for a car running 802.11, the report noted.”

Ask Slashdot: Video Monitors For Areas That Are Off the Grid?

Input Devices

An anonymous reader writes “I have a cottage at the end of a long dirt road, no electricity nor internet, and recently some (insert expletive here) wads are using the area as a trash dump: countertops, sofas, metal scraps, tvs — all the stuff they don’t want to pay to dump at the landfill. I can’t block the road because it’s a fire access. But I would really like to have a way to catch who is doing this. Are there any a) waterproof, b) self-contained, c) self-powered, and (ideally) d) inexpensive video-recording units out there? Are there any other creative ways to get the guys? I was thinking of something like a device that will cycle, so that the last week of video is recorded. It could take photos or video, and as long as it’s small enough that I could camouflage it well, I suspect I’d be able to figure this out soon. And any idea of what my legal rights are to videotape or record?” Hunters have been doing this for years (with film, and now digital) to figure out prey patterns with cameras that are built for concealment; what else would you recommend?

GM Working On Wi-Fi Direct-Equipped Cars To Detect Pedestrians and Cyclists

Transportation

cylonlover writes “General Motors is working to expand upon its vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication systems that allow information to be shared between vehicles and infrastructure to provide advance warning of potential road hazards, such as stalled vehicles, slippery roads, road works, intersections, stop signs and the like. The automaker is now looking to add pedestrians and cyclists to the mix using Wi-Fi Direct technology so a car can detect them in low visibility conditions before the driver does.”

How Satnav Maps Are Made

Google

Barence writes “PC Pro has a feature revealing how the world’s biggest satnav firms create their maps. Nokia’s Navteq, for example, has a huge database of almost 24 million miles of road across the globe. For each mile of road there are multiple data points, and for each of those positions, more than 280 road attributes. The maps are generated from public data and driver feedback, not to mention its own fleet of cars with 360-degree cameras on the top.There’s an IMU (inertial measurement unit) for monitoring the pitch of the road, and the very latest in 3D surface-scanning technology too. This light detection and ranging (LIDAR) detector captures 1.3 million three-dimensional data points every second, mapping the world around Navteq’s field vehicles in true 3D. The feature also investigates whether commercial mapping firms will be replaced by open-source maps.” That last line makes me think of the difference between conventionally published encyclopedias and Wikipedia; “replaced by” is an odd standard in a big marketplace of ideas.

Ask Slashdot: Syncing Files With Remote Server While On the Road?

Data Storage

An anonymous reader writes “Here’s a scenario: you are on a vacation trip for a couple of weeks — on the road. Lots of pictures — 2-300 per day. Maybe some text files with short notes etc. You have a camera with Eye-Fi, a PC, and a phone with WiFi and 3G. Files ends up on the PC (mobile storage), phone provides Internet connectivity. Now, if you wanted to upload all files pretty much as you go — given spotty access to Internet over G3 and WiFi — what would be the best way to do that automatically; set-it-and-forget-it style? I would like them to end up on my own server. rsync script? ownCloud? Some BitTorrent setup? Other? I’m thinking of interrupted file transfers due to no network, re-starts etc. And I would not want to lose any files; including scenarios where files gets deleted locally — that should not result in files getting automatically deleted on the server as well. Sure; I could perhaps use something like Dropbox but that would take the fun out of it.”

Autonomous Road Train Project Completes First Public Road Test

Transportation

theodp writes Covered earlier on Slashdot, but lost in the buzz over the Google driverless car is Project Sartre (Safe Road Trains for the Environment), Europe’s experiment with ‘vehicle platooning,’ which has successfully completed a 125 mile road test on a busy Spain motorway. Three Volvos drove themselves by automatically following a truck in the presence of other, normal road users. The Register reports that on-board cameras, radar and laser tracking allow each vehicle to monitor the one in front, and wirelessly streamed data from the lead vehicle tells each car when to accelerate, break and turn.”

Ask Slashdot: Who Has the Best 3G Coverage In California and Nevada?

Wireless Networking

New submitter derchris writes “We will be on vacation in the U.S. next month for about 3 weeks. We are going to do a road trip between San Francisco, Las Vegas and Los Angeles. To not use roaming for data, and get a heart attack once back home looking at the mobile bill, I was looking at so called ‘MiFi’ devices, portable 3G Wi-Fi hotspots. As far as I know, more or less all of the U.S. carriers have such devices available. But as I’m not from the U.S., I have no idea what would give me the best 3G coverage in the areas we are travelling. Another question would be whether I can buy one of these devices off eBay, and use it with any SIM card. Let’s hope there are users available who could give some advice on this topic.”
