Amazon debuts a scale model autonomous car to teach developers machine learning – TechCrunch

Published

on

Amazon today announced AWS DeepRacer, a fully autonomous 1/18th-scale race car that aims to help developers learn machine learning. Priced at $399 but currently offered for $249, the race car lets developers get hands-on — literally — with a machine learning technique called reinforcement learning (RL).

RL takes a different approach to training models than other machine learning techniques, Amazon explained.

It’s a type of machine learning that works when an “agent” is allowed to act on a trial-and-error basis within an interactive environment. It does so using feedback from those actions to learn over time in order to reach a predetermined goal or to maximize some type of score or reward.

This makes it different from other machine learning techniques — like Supervised Learning, for example — as it doesn’t require any labeled training data to get started, and it can make short-term decisions while optimizing for a long-term goal.

The new race car lets developers experiment with RL by learning through autonomous driving.

Developers first get started using a virtual car and tracks in a cloud-based 3D racing simulator, powered by AWS RoboMaker. Here, they can train an autonomous driving model against a collection of predefined race tracks included with the simulator, then evaluate them virtually or choose to download them to the real-world AWS DeepRacer car.

They can also opt to participate in the first AWS DeepRacer League at the re:Invent conference, where the car was announced. This event will take place over the next 24 hours in the AWS DeepRacer workshops and at the MGM Speedway and will involve using Amazon SageMaker, AWS RoboMaker and other AWS services.

There are six main tracks, each with a pit area, a hacker garage and two extra tracks developers can use for training and experimentation. There will also be a DJ.

The league will continue after the event, as well, with a series of live racing events starting in 2019 at AWS Global Summits worldwide. Virtual tournaments will also be hosted throughout the year, Amazon said, with the goal of winning the AWS DeepRacer 2019 Championship Cup at re:invent 2019.

As for the car’s hardware itself, it’s a 1/18th-scale, radio-controlled, four-wheel drive vehicle powered by an Intel Atom processor. The processor runs Ubuntu 16.04 LTS, ROS (Robot Operating System) and the Intel OpenVino computer vision toolkit.

The car also includes a 4 megapixel camera with 1080p resolution, 802.11ac Wi-Fi, multiple USB ports and battery power that will last for about two hours.

It’s available for sale on Amazon here.

Android phones get PC webcam capabilities in the latest beta

Published

on

Here’s a fun new use for your Android phone: A PC webcam! In the latest Android beta, plugging a phone into a PC will reveal a new option in the USB Preferences menu for webcam functionality. Just pick that option instead of the default “file transfer,” and the phone camera will register itself as a webcam. Then you can fire up Zoom and start video calling.

The Android build with this feature is “Android 14 QPR1 Beta 1.” Android’s getting confusing with all these overlapping betas, but the current stable version is still Android 13. Android 14, currently on its 10th beta/developer preview, will most likely be out alongside the Pixel 8 in October. Android 14 QPR1 is the quarterly release after the first stable build of Android 14, and it should be out around December. (QPR stands for quarterly platform release.) These happen between major releases, often marketed as “feature drops.” Right now, Android 13 is technically “Android 13 QPR3.”

Android is technically copying this feature from iOS. In Apple land, this is called the “Continuity Camera,” and will work wirelessly between an iPhone and a Mac, which is pretty cool. As usual, the Android version is much more flexible since the feature presents as a generic USB webcam. It should work on almost everything, like Windows, Mac, Chrome OS, and probably Linux. You can even plug an Android phone into another Android phone and use the first phone’s camera as the webcam for the second phone.

A phone has a lot more thickness to work with than the top half of a laptop, so most phone cameras will outclass any camera that has been crammed into the paper-thin screen portion of a laptop. The hard part is coming up with a viable phone mount that puts the camera in the right location. You’ll also still need some kind of microphone, as you can’t use the phone’s mic yet. Hopefully that gets fixed in time for the stable releases.

Apple’s new iPhone 15 and 15 Pro reach doorsteps and store shelves

Published

Apple

Today marks the in-store launch of the iPhone 15 and iPhone 15 Pro, plus the likely delivery date for at least the earliest preorders. Preorders went live a week ago, on September 15.

You’ll be waiting for a while if you want the Pro model and didn’t preorder, though.

In Chicago, delivery dates for new orders of the iPhone 15 Pro and iPhone 15 Pro Max from the online Apple store are currently estimated to be between October 23 and 30—more than a month from now. Next-day in-store pickup is still a possibility for most configurations, except for the 1TB iPhone 15 Pro Max.

The regular iPhone 15 and iPhone 15 Plus don’t seem to have the same problem, though. I was offered immediate shipping or pick-up for every configuration I tried. All these estimates could be different not long after this is published, of course.

It’s tempting to look at that information and conclude that the Pro models will be more popular during this year’s cycle, but that’s not necessarily the case. It depends on how many units of each model Apple has produced, of course, and it stands to reason that early adopters who jumped right on preorders last week are enthusiasts who might be more interested in the Pro models.

A handful of companion products to the iPhone 15 lineup are also available today, including USB-C AirPods Pro and MagSafe chargers.

We currently have the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max in hand and are working on a review that will go live next week.

In case you missed the announcement a couple of weeks ago, the iPhone 15 brings several of the “Pro” features from the iPhone 14 Pro to the current base iPhone, including the Dynamic Island to replace the notch, Apple’s A16 chip, and a 48-megapixel camera sensor that is used to facilitate 2x zoom, among other things. It also ditches the long-standing proprietary Lightning connection in favor of the industry-standard USB-C.

The iPhone 15 Pro distinguishes itself from the base model with a new configurable “Action Button” to replace the mute switch, a faster USB-C port, a more robust camera system, a faster A17 chip, which claims notably improved graphics performance, and a new titanium enclosure. The phones’ general sizes, designs, and shapes are very similar to what we saw last year.

Amazon adding ads to Prime Video in 2024 unless you pay $2.99 extra

Published

on

Next year, watching TV shows and movies on Amazon Prime Video without ads will cost more than it does now. In early 2024, Amazon will show ads with Prime Video content unless you pay $2.99 extra.

Amazon announced today that Prime Video users in the US, Canada, Germany, and the UK will automatically start seeing advertisements “in early 2024.” Subscribers will receive a notification email “several weeks” in advance, at which point they can opt to pay $2.99 extra for ad-free Prime Video, Amazon said.

That takes the price of ad-free Prime Video from $8.99/month alone to $11.98/month and from $14.99/month with Prime to $17.98/month.

Here’s how that compares against other ad-free streaming service tiers:

  • Apple TV+: $6.99
  • Disney+: $13.99 (starting October 12)
  • Netflix: $15.49
  • Hulu: $17.99 (starting October 12)
  • Paramount+: $11.99
  • Peacock: $11.99

Amazon said it’s making this change “to continue investing in compelling content and keep increasing that investment over a long period of time.” Prime Video is an expensive endeavor, costing Amazon $16.6 billion in 2022, with $7 billion of that spent on original content.

The Wall Street Journal reported in June that Amazon was considering introducing an ad-supported Prime Video tier amid high interest from advertisers. The company is already heavily invested in advertising, with its second-quarter earnings reporting advertising services growing 22 percent year over year to $10.9 billion. Amazon follows only Google and Meta in terms of digital ad revenue, according to Insider Intelligence.

Some Prime Video content already has product placement, and sports programming on Prime Video has ads. But bringing ads to the entire service gives Amazon the ability to generate more revenue from ads and from people who decide to cough up the extra cash to avoid seeing commercials.

Prime Video subscribers who don’t pay the extra $2.99 (and don’t just cancel their subscription altogether) are promised “meaningfully fewer ads than linear TV and other streaming TV providers.”

Amazon did not provide further details about the upcoming change. However, Max says it shows “about 4 minutes of ads per hour,” and Peacock shows up to 5 minutes per hour. A May report from Insider Intelligence citing data from advertising analyst MediaRadar said Disney+ shows 5.3 minutes of ads per hour, Netflix four minutes, and Hulu 7.3 minutes.

With current prices starting at $9.99 per month, Prime Video was one of the cheapest ways to get streaming TV without ads. While the changes put pricing for ad-free Prime Video more on par with its competitors, it may still disappoint budget-minded cord-cutters. Streaming services started off as a cheaper, simpler alternative to cable TV. But as an influx in services, changes in pricing, confusing bundles, and scattered content have proven, we haven’t gotten that far from cable after all.
