teslas self-driving car

Tesla CEO Elon Musk has made a bold prediction: Tesla Motors will have a self-driving car within two years.

“I think we have all the pieces,” Musk told Fortune, “and it’s just about refining those pieces, putting them in place, and making sure they work across a huge number of environments — and then we’re done. It’s a much easier problem than people think it is.”

Although Musk’s comments to Fortune came Monday, The Street pegged a rise in Tesla’s shares to the comments on Tuesday. The ambitious timeframe appeared to be offering support to the stock again today, with shares trading up $1.47, or 0.64 percent, at $231.42 around 7:18 a.m. PST.

Musk’s driverless-car comments may have been overshadowed initially by the achievement of SpaceX on Monday night in landing a rocket during a commercial mission for the first time. Musk is also CEO of SpaceX.

This is the most aggressive timeline Musk has mentioned. While Musk claims the problem is easier than people think it is, he doesn’t think the tech is so accessible that any hacker could create a self-driving car. Musk took the opportunity to call out hacker George Hotz, who claimed via a Bloomberg article last week that he had developed self-driving car technology that could compete with Tesla’s. Musk said he wasn’t buying it.

“But it’s not like George Hotz, a one-guy-and-three-months problem,” Musk said to Fortune. “You know, it’s more like, thousands of people for two years.”

The company went so far as to post a statement last week about Hotz’s achievement.

“We think it is extremely unlikely that a single person or even a small company that lacks extensive engineering validation capability will be able to produce an autonomous driving system that can be deployed to production vehicles,” the company stated. “It may work as a limited demo on a known stretch of road — Tesla had such a system two years ago — but then requires enormous resources to debug over millions of miles of widely differing roads.”

While Tesla is unconcerned about Hotz, the company’s new timeline may have other autonomous car developers hitting the accelerator. Tech companies like Google and Apple, in addition to automakers such as Volvo and General Motors are all competing to be among the first to offer some form of self-driving tech. Many believe the early 2020s would be a realistic timeframe to expect to see the public engaging with self-driving cars.

Just yesterday, it was reported that Google and Ford will enter into a joint venture to build self-driving vehicles with Google’s technology, according to Yahoo Autos, citing sources familiar with the plans. The official announcement is expected to come during the Consumer Electronics Show in January, but there is no manufacturing timeline.

But even if Tesla moves quickly on self-driving cars, are consumers ready for them? The Palo Alto-based carmaker’s recent Firmware 7.1 Autopilot update includes restrictions on self-driving features. The update only allows its Autosteer feature to engage when the Model S is traveling below the posted speed limit. The update came shortly after it was reported that drivers were involved in dangerous activities while the Autopilot features were engaged.

Look out Elon – Porsche showing off the Mission E

In September, Porsche showed off the Mission E, a fully electric and fully beautiful concept made to dethrone Tesla motors as the EV industry’s king of cool.

Today, Porsche announced it’s investing more than a billion dollars to bring the Mission E to production. As in, you’ll be able to buy one. We’re light on details—like the size of the battery, or when we’ll actually see one on the road—but we’ve got the most important numbers. The motor (or motors, Porsche hasn’t said) will produce more than 600 horsepower. The four-seater Mission E will go from 0 to 62 mph in under 3.5 seconds. And it will go 310 miles on a charge.

Porsche, which faces increasingly strict fuel emission standards from US and European authorities, been working with batteries for a few years now, with top notch results. It already offers plug-in hybrid versions of the Panamera and Cayenne, it’s successfully raced a 911 hybrid. Then there’s the flat-out amazing gas-electric 918 Spyder supercar and 919 Hybrid that won at Le Mans this year. So it makes sense to make the next step a full electric.

Compared to Tesla’s current range-topper, the excellent Model S P90D, the Mission E will offer a bit less power and a slower acceleration time. But Porsche wins on range—the longest-legged Tesla goes roughly 286 miles on a charge. Here, the Germans have a second advantage: They’re working on an 800-volt charger that will power the car up to 80 percent in just 15 minutes, half the time it takes the Tesla.

Porsche plans to build the battery into the floor of the car, like Tesla does, so you can expect a very low center of gravity, great news for performance. But really, the Mission E wins on looks. The Model S and Model X SUV are lovely designs, but the Porsche is simply gorgeous, in the way only a Porsche can be. We’ve only seen the concept version, but hopefully Porsche will be smart enough to change as little as possible on the way to production.

Apples Job Interview Questions

Apple is known for being one of the most challenging and exciting places to work, so it’s not surprising to learn that getting a job there is no easy task.

Like Google and other big tech companies, Apple asks both technical questions based on your past work experience and some mind-boggling puzzles.

We combed through recent posts on Glassdoor to find some of the toughest interview questions candidates have been asked.

Some require solving tricky math problems, while others are simple but vague enough to keep you on your toes.

“If you have 2 eggs, and you want to figure out what’s the highest floor from which you can drop the egg without breaking it, how would you do it? What’s the optimal solution?” — Software Engineer candidate

“Who is your best friend?” — Family Room Specialist candidate

„Describe an interesting problem and how you solved it.“ — Software Engineer candidate

„You have a 100 coins laying flat on a table, each with a head side and a tail side. 10 of them are heads up, 90 are tails up. You can’t feel, see or in any other way find out which side is up. Split the coins into two piles such that there are the same number of heads in each pile.“ — Software Engineer candidate
