Tagged: google, Pixel 2 XL
The Pixel 2 XL launch hasn’t been going so well for Google. Early complaints were about the screen: how it had alleged burn-in problems within the first few days, and how it couldn’t support the sRGB color space. Since then, we’ve even been hearing reports that some phones shipped without the OS even installed. Whoops!
Now here’s a specific complaint: people are saying that the phone is charging slow. This is an easy one to test – run a multimeter in-line with the USB cable see what happens. Google+ user, Nathan K., apparently did, and he found that the Pixel 2 XL maxed out at 10.5W. When the screen is on, this drops to a maximum of 6W, which he claims (and I would have guessed) is likely due to the combined heat of a phone that’s both in-use and charging. Lithium batteries are very sensitive to heat.
He also says that this issue isn’t really a problem in-and-of itself. He just wishes that manufacturers advertised more about how the battery should perform, and maybe even provide the switches for users to override if needed. I could see that being a warranty nightmare, but I’m rarely going to fall on the side against user choice as a general rule, so I think that would be nice.

Remember last month? Remember when I said that Google’s introduction of Tesla P100s would be good leverage over Amazon, as the latter is still back in the Kepler days (because Maxwell was 32-bit focused)?
To compare the two parts, the Tesla P100 has 3584 CUDA cores, yielding just under 10 TFLOPs of single-precision performance. The Tesla V100, with its ridiculous die size, pushes that up over 14 TFLOPs. Same as Pascal, they also support full 1:2:4 FP64:FP32:FP16 performance scaling. It also has access to NVIDIA’s tensor cores, which are specialized for 16-bit, 4x4 multiply-add matrix operations that are apparently common in neural networks, both training and inferencing.
Amazon allows up to eight of them at once (with their P3.16xlarge instances).
So that’s cool. While Google has again been quickly leapfrogged by Amazon, it’s good to see NVIDIA getting wins in multiple cloud providers. This keeps money rolling in that will fund new chip designs for all the other segments.

Tagged: pixelbook, google, convertible tablet, Chromebook, chrome os
Google is dipping its Chrome toes into high end Chromebook territory again with the launch of a new thin and light convertible tablet called the Google Pixelbook. The 12.3” notebook is constructed of premium aluminum and glass components and packs 8th Generation refreshed Kaby Lake CPUs, up to 16 GB of RAM, and up to 512 GB of solid state storage. The Pixelbook has a Yoga-style folding multi-touch display and measures less than half an inch think (10.3mm) and weighs a smidge over 2 pounds (1.1kg).
The Pixelbook has a classy two tone metal and glass design with straight lines and flat edges save for the front edge that has rounded corners. On the inside, the top half is dominated by a 12.3” touchscreen with a resolution of 2400x1600 (Google did not reveal the panel type but did note that it has enough brightness to be used outdoors), paired with a webcam. The display and Wi-Fi antenna area are covered with glass. The bottom half features a backlit keyboard and trackpad that uses almost all the available space of the 12.3” Chromebook.
Internally, the Pixelbook is powered by an Intel Kaby Lake (refresh) processor (in i5 or i7 SKUs), from 8 GB to 16 GB of RAM, and 128 GB, 256 GB, or 512 GB of SSD storage depending on the model you purchase. Google has set up the Pixelbook so that it can automatically pair with a Pixel smartphone for tethered data on the go. The battery in the Pixelbook is rated for 10 hours and has a quick charge feature that offers up to 2 hours of usage on a 15-minute charge.
The display is multi-touch, and users can optionally purchase the new (Wacom developed) active electrostatic Pixelbook Pen for $99 and use the AI-powered handwriting recognition and Google Assistant functionality with the stylus. Google claims the pen has 2,000 levels of pressure sensitivity and 60-degrees of angular recognition, and thanks to machine learning, 10ms response time.
Speaking of Google Assistant, the Pixelbook features a Google Assistant key on the keyboard where the Windows key normally resides. The pen can be used to highlight text and interact with the AI assistant as well.
The Google Pixelbook is available for pre-order now at the Google Web Store and Best Buy and will be up for purchase by October 31st. The base model with an i5, 8GB of RAM, and 128 GB of SSD storage is $999. Moving to 256 GB of storage gets you to $1199 and upgrading all the specs to an i7, 16 GB RAM, and 512 GB NVMe SSD pushes the price to $1699.
The high-end Chromebook is a bit of an odd market, but the primarily web application-based Chrome OS continues to inch towards being able to take advantage of the local processing power with the ability to run apps not only from the Chrome Web Store but also run Android applications and store and run more stuff (like media and document creation) when offline. No doubt the Pixelbook looks classy, but it is putting itself in the same territory as iPad Pros and Surface products (Surface Books and Surface Pro tablets) as well as most of the premium ultrabook and thin and light laptop and tablets running full versions of Windows.
What are your thoughts on the new Pixelbook? Would you buy one?

Google has announced the Pixel 2 and Pixel 2 XL smartphones, the second-gen versions of the Nexus-replacement Pixel which launched last October. We looked at that first Pixel phone, which was the premier Android device at the time, and these new Pixel 2 devices hope to place Google at the top of the heap again (with stiff competition from Samsung, of course).

The Pixel 2 arrives in a standard version with a 5-inch 1920x1080 AMOLED display, and an XL version with a new 6-inch pOLED display with 2880x1440 resolution. Both phones are powered by the 8-core Snapdragon 835 and feature 4GB of RAM and the option of either 64GB or 128GB of storage (no card slot on either phone).
While the design of the Pixel 2 is largely unchanged compared to last year, with large bezels above and below the display, the Pixel 2 XL comes closer to the ever-popular “all screen” look with its smaller top/bottom bezels.

Both phones offer dual front-facing stereo speakers as well, unlike iPhones which have to combine an earpiece speaker and bottom-firing speaker for their stereo effect. The battery capacities are a little different than last year with both Pixel 2 phones, with a 2700 mAh battery (down from 2770 mAh) in the Pixel 2, and a 3520 mAh battery (up from 3450 mAh) in the Pixel 2 XL.
It’s all about camera
Once again, Google is proclaiming the Pixel 2 camera as the best in the industry, and again this is based on testing from DxOMark which has it ranked #1 overall among smartphones. with an incredible 98 out of a possible 100 in their scoring system.

Both sizes of Pixel 2 offer a single 12.2 MP rear camera (sorry, no dual cameras here) with 1.4μm pixels, laser + dual pixel phase detection autofocus, OIS, and a f/1.8 aperture. Fans of simulated lens bokeh have no fear, as Google’s dual-pixel sensor design is said to allow for better portrait-style photos than the original Pixel. Video of up to 4k (but only at 30 FPS) is supported, and an 8 MP f/2.4 camera handles front-facing duties.
More on those new displays
Google has improved the display technology with the Pixel 2, as both versions now offer wide color gamut support (95% DCI-P3 coverage from the Pixel 2, and a full 100% DCI-P3 from the Pixel 2 XL). The displays are now ‘always on’, a handy feature that makes sense from a power standpoint when working with AMOLED panels (and hard to give up once you’ve grown accustomed to it as I did with the Galaxy S8+). Last but not least, covering these new displays is Corning Gorilla Glass 5, which is the most drop-resistant version to date (and is also found on the Galaxy S8/S8+ among other phones).

The Pixel 2 XL’s “pOLED” display designation suggests a polymer OLED panel, which has the advantage of being much thinner than traditional glass OLED substrates. (Read more about AMOLED vs. P-OLED here.)
The Pixel 2 phones ship with the new Android 8.0 Oreo, with the promise of “minimum” 3 years of OS and security updates. Vanilla Google phone owners (previously Nexus) have enjoyed being the first to new OS updates, and that should still be the case with these new devices. And if you are coming over from another platform - say, Apple, for instance - a “quick switch” adapter is in every box to help transfer data quickly between phones.

Google is offering the (unlocked) phone for sale directly from their website, and have partnered with Verizon as the exclusive mobile carrier as they did with the original Pixel. The price? $649 gets you the 5-inch Pixel 2 with 64GB of storage, or double that to 128GB for $100 more. The Pixel 2 XL is available for $849 for the 64GB capacity, with the same $100 premium for a 128GB version. There are also four color options this year, with the whimsical naming fully intact from the previous generation: Just Black, Clearly White, Kinda Blue, and Black & White.
Oh, and one more thing: the 3.5 mm headphone jack is gone.

Tagged: google, nvidia, p100, GP100
NVIDIA seems to have scored a fairly large customer lately, as Google has just added Tesla P100 GPUs to their cloud infrastructure. Effective immediately, you can attach up to four of these GPUs to your rented servers on an hourly or monthly basis. According to their pricing calculator, each GPU adds $2.30 per hour to your server’s fee in Oregon and South Carolina, which isn’t a lot if you only use them for short periods of time.
If you need to use them long-term, though, Google has also announced “sustained use discounts” with this blog post, too.
While NVIDIA has technically launched a successor to the P100, the Volta-based V100, the Pascal-based part is still quite interesting. The main focus of the GPU design, GP100, was bringing FP64 performance up to its theoretical maximum of 1/2 FP32. It also has very high memory bandwidth, due to its HBM 2.0 stacks, which is often a huge bottleneck for GPU-based applications.
For NVIDIA, selling high-end GPUs is obviously good. The enterprise market is lucrative, and it validates their push into the really large die sizes. For Google, it gives a huge reason for interested parties to consider them over just defaulting to Amazon. AWS has GPU instances, but they’re currently limited to Kepler and Maxwell (and they offer FPGA-based acceleration, too). They can always catch up, but they haven’t yet, and that's good for Google.

So this is a bit of a weird one. As our readers are probably well aware, Google Maps offers Street View, which allows you to see 360-degree images from a car as it travels as many roads as it can... since, like, 2007. Also, this year, they are beginning to upgrade the quality of these images with new cars. Now that VR is taking off, it would be kind-of cool to see this data around you. Daydream (and apparently Cardboard) have an app that offers a few locations that you can view... sort-of like you would see in QuickTime in the 90s. Meanwhile, on Oculus, you had Google Earth, which let you see a view that was based on their new 3D Google Maps Satellite view, but it wouldn’t pull in the Street View data.
Image Credit: Google
Now it will. A couple of days ago, Google updated Google Earth VR to allow teleporting into that spherical image. You will see a preview in a sphere atop your left hand. The weird part, though, is that you can’t travel while within street view. As far as I can tell, you need to jump back to the satellite view, move, then drop back down into street view any time you want to go anywhere. This... makes little sense to me, unless they plan on adding that feature but it just didn’t make this release schedule. It seems like they have all of the pieces scattered across existing software, but it's obviously next-to-impossible to tell for sure from the outside. Perhaps the data linked into the web-based Street View is insufficient for some reason?
Rant aside, if you have a compatible headset (which Steam says is an Oculus Rift or an HTC Vive) then it’s worth a free download to check it out.

If you missed out on having all your files encrypted and the chance to send bitcoin to a bunch of misanthropes who have no plans on unencrypting those files after you do, then download this new app from Google Play! Then you can enable SMBv1 on all your other machines so your Android can share the virus amongst your other machines, perhaps you could even share this unforgettable experience with your friends and family. Do you really trust that the patches applied to this outdated network file sharing protocol will protect from the next wave of attacks or will you follow the advice from Microsoft's Ned Pyle that The Register quoted, "Stop using SMBv1". There are a lot of other ways to share your files, most are even more effective than SMBv1 and are certainly more secure.
"This made Google's decision so odd, The Register wondered if the app were faking the Google brand, but no: the source code linked from the app is at the Chocolate Factory's GitHub repo."

Qualcomm has put forward steady work on creating the vibrant hardware ecosystem for mobile VR to facilitate broad adoption of wireless, dedicated head mounted displays. Though the value of Samsung’s Gear VR and Google’s Daydream View cannot but overstated in moving the perception of consumer VR forward, the need to utilize your smart phone in a slot-in style design has its limitations. It consumes battery that you may require for other purposes, it limits the kinds of sensors that the VR system can utilize, and creates a sub-optimal form factor in order to allow for simple user installation.
The Qualcomm Snapdragon 835 VR Reference Device
Qualcomm created the first standalone VR HMD reference design back in early 2016, powered by the Snapdragon 820 processor. Google partnered with Qualcomm at I/O to create the Daydream standalone VR headset reference design with the updated Snapdragon 835 Mobile Platform at its core, improving performance and graphical capability along the way. OEMs like Lenovo and HTC have already committed to Daydream standalone units, with Qualcomm at the heart of the hardware.
Qualcomm Technologies recently announced a HMD Accelerator Program (HAP) to help VR device manufacturers quickly develop premium standalone VR HMDs. At the core of this program is the standalone VR HMD reference design. It goes beyond a simple prototype device, offering a detailed reference design that allows manufacturers to apply their own customizations while utilizing our engineering, design, and experience in VR. The reference design is engineered to minimize software changes, hardware issues, and key component validation.
- Hugo Swart, Qualcomm Atheros, Inc.
As part of this venture, and to continue pushing the VR industry forward to more advanced capabilities like XR (extended reality, a merger of VR and AR), Qualcomm is announcing agreements with key component vendors aiming to tighten and strengthen the VR headset ecosystem.
Hugo Swart, Senior Director, Product Management, Qualcomm Atheros, Inc.
Ximmerse has built a high-precision and drift-free controller for VR applications that offers low latency input and 3DoF (3 degrees of freedom) capability. This can “provide just about any interaction, such as pointing, selecting, grabbing, shooting, and much more. For precise 6 DoF positional tracking of your head, tight integration is required between the sensor fusion processing (Snapdragon) and the data from both the camera and inertial sensors.”
Bosch Sensortec has the BMX055 absolute orientation sensor that performs the function that its name would imply: precisely locating the user in the real world and tracking movement via accelerometer, gyroscope, and magnetometer.
Finally, OmniVision integrates the OV9282 which is a 1MP high speed shutter image sensor for feature tracking.
These technologies, paired with the work Qualcomm has already done for the Snapdragon 835 VR Development Kit, including on the software side, is an important step to the growth of this segment of the market. I don’t know of anyone that doesn’t believe standalone, wireless headsets are the eventual future of VR and AR and the momentum created by Qualcomm, Google, and others continues its steady pace of development.
Introduction and Design
In case you have not heard by now, Pixel is the re-imagining of the Nexus phone concept by Google; a fully stock version of the Android experience on custom, Google-authorized hardware - and with the promise of the latest OS updates as they are released. So how does the hardware stack up? We are late into the life of the Pixel by now, and this is more of a long-term review as I have had the smaller version of the phone on hand for some weeks now. As a result I can offer my candid view of the less-covered of the two Pixel handsets (most reviews center around the Pixel XL), and its performance.
There was always a certain cachet to owning a Nexus phone, and you could rest assured that you would be running the latest version of Android before anyone on operator-controlled hardware. The Nexus phones were sold primarily by Google, unlocked, with operator/retail availability at times during their run. Things took a turn when Google opted to offer a carrier-branded version of the Nexus 6 back in November of 2014, along with their usual unlocked Google Play store offering. But this departure was not just an issue of branding, as the price jumped to a full $649; the off-contract cost of premium handsets such as Apple’s iPhone. How could Google hope to compete in a space dominated by Apple and Samsung phones purchased by and large with operator subsidies and installment plans? They did not compete, of course, and the Nexus 6 flopped.
Pixel, coming after the Huawei-manufactured Nexus 6p and LG-manufactured Nexus 5X, drops the “Nexus” branding while continuing the tradition of a reference Android experience - and the more recent tradition of premium pricing. As we have seen in the months since its release, the Pixel did not put much of a dent into the Apple/Samsung dominated handset market. But even during the budget-friendly Nexus era, which offered a compelling mix of day-one Android OS update availability and inexpensive, unlocked hardware (think Nexus 4 at $299 and Nexus 5 at $349), Google's own phones were never mainstream. Still, in keeping with iPhone and Galaxy flagships $649 nets you a Pixel, which also launched through Verizon in an exclusive operator deal. Of course a larger version of the Pixel exists, and I would be remiss if I did not mention the Pixel XL. Unfortunately I would also be remiss if I didn't mention that stock for the XL has been quite low with availability constantly in question.
The Pixel is hard to distinguish from an iPhone 7 from a distance (other than the home button)
