I had been testing out Vi, a set of $249 Bluetooth running headphones with its own built-in AI assistant and biometric tracking features. After a convoluted series of events in which I was offered a potentially illegal entry to the Brooklyn Half Marathon a week before the race, I found my adventure: I decided to run my own 13.1 miles in the Prospect Park Loop with nothing but the AI headphones to guide me, using Vi for a crash training course to prep in less than a week. Vi doesn't offer much more than other running apps I've used: It tracks the distance you run, measures your heart rate, and offers some realtime coaching direction to fine-tune your step rate to find your ideal pace, which it calls your "Comfort Zone," -- but it leaves much to be desired as a next-gen personal trainer. It currently has no dedicated feature to set specific goals, so users prepping for races like me have no guide to train for big events or set more defined goals than just fine-tuning their running style.

No, not allegedly propositioning your subordinates for sex, but pleading the Fifth Amendment in a massive court case in which you're accused of stealing Google's self-driving car technology and bringing it to Uber. SEE ALSO: Mark Zuckerberg and Travis Kalanick laugh it up at'Babes and Balls' party So reports The New York Times, which notes that the news of Anthony Levandowski's ousting was delivered to Uber employees Tuesday in a companywide email written by Uber Associate General Counsel Angela Padilla. An Uber spokesperson confirmed the shake up to Mashable, and insisted that Levandowski forced the company's hand. Uber denies Waymo's allegations, but is clearly no longer willing to tolerate Levandowski either way.

New rule: From now on, all sporting events must begin with an official bringing the game ball to the referee via the magic of drone-style hoverboard vehicles. That can be the only conclusion after watching the absolutely insane demonstration recorded at the Portuguese Cup Final on Sunday, which started with a man riding on air, Green Goblin style, and landing delicately in front of a ref to deliver the game's soccer ball. It was what every sports event with a ball should have from this very moment on.

At least that's the obvious conclusion based on Snap's acquisition of Ctrl Me Robotics for "under $1 million," a deal that was first reported by Buzzfeed on Friday. Although the report calls the Venice Beach-based company a drone manufacturer, a subsequent report from Variety indicates that Ctrl Me Robotics' true expertise is customizing existing drones to be able to carry cameras rather than specializing in producing drones. Additionally, the Variety report claims that the deal actually occurred late last year. Although it's unclear what Snap's plans are for the company's expertise, a least one hint may rest in an Instagram post from Ctrl Me Robotics from almost two years ago.

For this, Turgeon was arrested and charged with felony and misdemeanor counts of reckless endangerment as well as a misdemeanor count of physical obstruction of a government function, according to Motherboard. At about 33 minutes into the video below, you can see what is alleged to be Turgeon's drone flying nowhere close to a North Dakota Highway Patrol plane that is also in frame. The misdemeanor reckless endangerment charge came from allegedly flying a drone above protesters, "creating a substantial risk of serious bodily injury or death."

The Swedish home design retailer's TRÅDFRI smart lighting system will soon be compatible with some of the most common smart home hubs on the market: Apple Homekit, Google Home, and Amazon Alexa. The TRÅDFRI system will also be far cheaper than other connected lights on the market, making the platform an enticing gateway for homeowners holding off on smart appliances because of their high cost. The Swedish home design retailer first announced its smart lighting system as part of its push to make homes more connected back in March, but at that point it wasn't compatible with any of the major smart home platforms, as users were left controlling the lighting with a dedicated remote control or the TRÅDFRI app. Smart bulbs don't quite measure up to a pair of custom Yeezys on the coolness scale, but the new compatibility will make the lights much more useful on the path to making connected homes cheaper for everyone.

Earlier Tuesday, Uber announced the first successful run of one of its self-driving freight trucks, developed by San Francisco-based company Otto. The truck, designed by Otto, successfully completed a 120-mile journey between Fort Collins, Colorado and Colorado Springs, Colorado, delivering 2,000 cases of Budweiser beers with nary an issue along its journey on Interstate 25. So what's the deal with Otto, the company acquired by Uber in August, driving (pun intended) this push of self-driving technology? When it launched, Otto estimated that the price of its autonomous drive system would be a "small fraction" of the 100,000 to 200,000 price tag of a brand-new semi truck.

Those microphones are backed by Intel's Real Audio technology, a natural language processing system that can respond to commands and questions, and follow context. The Oakley Radar Pace system responded with the beats per minute measurement. It even includes touch sensitive controls, which you can use to access music and talk to Intel Real Audio. For all the built-in technology and sensors, the Radar Pace lacks a heart rate monitor, which means that, if you want to track that key workout metric, you'll need to wear and connect to a third party device.

The dating app rolled out a new experience for iMessage, an app called Tinder Stacks, that allows people to create their own Tinder-like swiping experiences directly in their conversations. The idea behind Tinder Stacks is to give Tinder users a way to allow their friends to "vote" on collections of photos while they chat. Once set up, using Tinder Stacks is fairly straightforward: create a "stack" based on photos from your camera roll and share it with friends who can vote on the images you share. When Mashable published its list of the 100 greatest iPhone apps of all time, we noted the greatest contribution Tinder (#20) has made to the app world is its design.

A new speech recognition system can transcribe English or Mandarin about three times faster than humans can type on a smartphone, according to a recent study. SEE ALSO: Mark Zuckerberg's First Stop in China: Baidu Headquarters The study, a collaboration between Stanford University, Baidu and the University of Washington, also found that the system produced 20.4 percent fewer errors than people typing in English and 63.8 percent fewer than people working in Mandarin. "We're putting speech recognition up against people who are really good at this task," study co-author James Landay told Stanford News. The system produced 20.4 percent fewer errors than people typing in English and 63.8 percent fewer than people working in Mandarin.
