Today, at their Oculus Connect 5 developer conference, Facebook announced the Oculus Quest standalone VR headset.
Oculus Quest (previously codenamed Santa Cruz) is similar to the Oculus Go launched last year in that it's an entirely self-contained solution, with no need for an external device like a PC or phone.
Oculus Quest builds on what the Go offers in several significant ways. Quest provides 6 Degree of Freedom (DoF) movement and room scale tracking, compared to the 3-DoF system on the Go. This means that you will now be able to walk around a room, instead of just moving your head. For reference, both the Oculus Rift and HTC Vive (via external trackers), and the Lenovo Mirage Google Daydream headset offer 6-DoF movement functionality.
Additionally, Oculus Quest will ship with a full set of touch controllers, similar to the Oculus Rift, where Go only ships with a single controller that is more akin to a remote than a full game controller.
Compared to the Oculus Go's 1280 x 1440 per eye, the Oculus Quest also offers a much higher resolution of 1600x1440 resolution per eye.
Oculus Quest will sit alongside the Oculus Rift and Oculus Go, offering VR experiences at several different price points. Facebook has said the addition of this third device completes their roadmap, and that app compatibility will be retained for future products in each of these segmentations (e.g., Oculus Go apps will run on Oculus Go 2).
Facebook has said the Oculus Quest will offer "Rift-like" experiences, touting Quest versions of Robo Recall, The Climb, and Moss. However, we aren't exactly sure what hardware is powering the Oculus Quest to accomplish this. However, due to the form factor, we expect it to be similar to the Qualcomm Snapdragon-powered Oculus Go, especially given the limited 64GB on-board storage.
Oculus Quest is set to ship in Spring 2019, for a price of $399 (including the touch controllers).
Stay tuned for more details from Oculus Connect 5!
It's all fun and games until something something AI.
Microsoft announced the Windows Machine Learning (WinML) API about two weeks ago, but they did so in a sort-of abstract context. This week, alongside the 2018 Game Developers Conference, they are grounding it in a practical application: video games!
Specifically, the API provides the mechanisms for game developers to run inference on the target machine. The training data that it runs against would be in the Open Neural Network Exchange (ONNX) format from Microsoft, Facebook, and Amazon. Like the initial announcement suggests, it can be used for any application, not just games, but… you know. If you want to get a technology off the ground, and it requires a high-end GPU, then video game enthusiasts are good lead users. When run in a DirectX application, WinML kernels are queued on the DirectX 12 compute queue.
We’ve discussed the concept before. When you’re rendering a video game, simulating an accurate scenario isn’t your goal – the goal is to look like you are. The direct way of looking like you’re doing something is to do it. The problem is that some effects are too slow (or, sometimes, too complicated) to correctly simulate. In these cases, it might be viable to make a deep-learning AI hallucinate a convincing result, even though no actual simulation took place.
Fluid dynamics, global illumination, and up-scaling are three examples.
Previously mentioned SIGGRAPH demo of fluid simulation without fluid simulation...
... just a trained AI hallucinating a scene based on input parameters.
Another place where AI could be useful is… well… AI. One way of making AI is to give it some set of data from the game environment, often including information that a player in its position would not be able to know, and having it run against a branching logic tree. Deep learning, on the other hand, can train itself on billions of examples of good and bad play, and make results based on input parameters. While the two methods do not sound that different, the difference between logic being designed (vs logic being assembled from an abstract good/bad dataset) someone abstracts the potential for assumptions and programmer error. Of course, it abstracts that potential for error into the training dataset, but that’s a whole other discussion.
The third area that AI could be useful is when you’re creating the game itself.
There’s a lot of grunt and grind work when developing a video game. Licensing prefab solutions (or commissioning someone to do a one-off asset for you) helps ease this burden, but that gets expensive in terms of both time and money. If some of those assets could be created by giving parameters to a deep-learning AI, then those are assets that you would not need to make, allowing you to focus on other assets and how they all fit together.
These are three of the use cases that Microsoft is aiming WinML at.
Sure, these are smooth curves of large details, but the antialiasing pattern looks almost perfect.
For instance, Microsoft is pointing to an NVIDIA demo where they up-sample a photo of a car, once with bilinear filtering and once with a machine learning algorithm (although not WinML-based). The bilinear algorithm behaves exactly as someone who has used Photoshop would expect. The machine learning algorithm, however, was able to identify the objects that the image intended to represent, and it drew the edges that it thought made sense.
Like their DirectX Raytracing (DXR) announcement, Microsoft plans to have PIX support WinML “on Day 1”. As for partners? They are currently working with Unity Technologies to provide WinML support in Unity’s ML-Agents plug-in. That’s all the game industry partners they have announced at the moment, though. It’ll be interesting to see who jumps in and who doesn’t over the next couple of years.

Almost exactly two months after ZeniMax won a $500 million USD judgement against Oculus, subject to appeal, of course, co-founder Palmer Luckey will leave the company. As expected, Facebook isn’t commenting on who initiated this departure because of their corporate policy, and it would be inappropriate and unprofessional for a company to do so (except in certain circumstances).
Their official message, via UploadVR, is as follows:
Palmer will be dearly missed. Palmer’s legacy extends far beyond Oculus. His inventive spirit helped kickstart the modern VR revolution and helped build an industry. We’re thankful for everything he did for Oculus and VR, and we wish him all the best.
Brendan Iribe, another co-founder and former CEO of Oculus VR, is still at the company as far as we know. Last we heard, through his blog post on the company’s website, he’s moved to an internal team that focuses on their PC initiatives: the Rift, research, and computer vision.
For now, it’s somewhat unclear how the company is structured. John Carmack is supposedly still the CTO, but I don’t think Facebook has found anyone to replace Brendan Iribe as CEO yet. Today’s departure leaves another vacant hole, although, according to Tom Forsyth’s joke tweet, his title was “Palmer” and thus his role will likely be retired. Who knows? If your name just happens to be Palmer, then maybe you can apply for it.

Tagged: zenimax, VR, Oculus, facebook
On May 1st, 2014, ZeniMax, who owns id Software and Bethesda Softworks, sued Oculus VR, claiming that it had some ownership of their virtual reality technology. This accusation occurred about a month after Facebook announced that they were acquiring Oculus for $2 billion USD. At least part of their claim was due to work that John Carmack did before he left id Software the year prior, in August 2013.
Today, a North Texas jury awarded ZeniMax $500 million USD from Oculus. This figure is broken down as follows: $300 million against Oculus as a company, $50 million against Palmer Luckey as an individual, and $150 million against Brendan Iribe as an individual. The jury found John Carmack wasn’t responsible for any damages as an individual, so he’s clear of this whole issue.
Oculus and Facebook plan to appeal their judgments.
According to this decision, the jury believes that ZeniMax has some ownership over Oculus’ trademark and source code copyrights. They also believe that, again, according to the verdict, which is hosted by Ars Technica, Oculus violated a non-disclosure agreement that caused $200,000,000 in damages to ZeniMax, but will not continue to damage the company in the future. (See the few pages before Page 49, inclusive.) The personal judgments against Palmer Luckey and Brendan Iribe are due to the pair not acknowledging ZeniMax’s contributions to Oculus.
Update (February 2nd @ 12:30pm EST): As pointed out in the comments, that was an old tweet from 2014. I just came across it and somehow missed the date stamp. My mistake!
After this decision, John Carmack tweeted:
No work I have ever done has been patented. Zenimax owns the code that I wrote, but they don't own VR.
— John Carmack (@ID_AA_Carmack) May 1, 2014
As always, lots of things can change during the appeals process. For now, it looks like both ZeniMax and John Carmack received a little vindication, though.

Tagged: whatsapp, fud, facebook, encryption
By now you will have seen a headline screaming something about the security of Facebook's WhatsApp messaging service, ranging from somewhere between a backdoor purposefully inserted into the app to a complete denial of any security risk at all. The actual issue is much larger than WhatsApp and address a security issue with all applications which depend on public key encryption.
Many applications utilize public keys for their encryption, the encryption relies on keys unique to the sender and receivers devices and which use the public key to verify the authorization of a new device. If your accounts key was permanently attached to a specific piece of hardware you would need a separate account for each device you used, which would be quite onerous.
The issue is that the Open Whisper Signal protocol is configured by WhatsApp in a way which makes the data vulnerable to a man in the middle attack. If you can managed to block the transmission of a message, then take over one of the authorized devices accounts or phone numbers and trigger the generation of a new private key via a public key request to Facebook then you will be able to read messages until people realize what is going on. This is not impossible but far from easy to accomplish, and effects any similar encryption system, not just WhatsApp.
Perhaps more worrying is Facebook's ability to take advantage of this, as they can generate a new public key to read messages, if they so choose. If you are concerned about this, you can enable the Show Security Notifications setting under Settings -> Account -> Security to be notified whenever a contact's security code has changed. The Register links to several articles which delve into the technology as well as the media's reactions here, if you are interested.
"The problem – which is "endemic to public key cryptography" – was raised in April last year, and at the time WhatsApp said it wasn't a serious enough design flaw to spend time fixing."

Tagged: blizzard, facebook, OBS
So I was greeted with an interesting pop-up when I updated my Battle.net launcher today. Turns out Blizzard is pushing Blizzard Streaming to “the Americas, Southeast Asia, Australia, and New Zealand”. Currently, Facebook is the only platform that you can stream to, and Blizzard hasn't announced bringing it to others, but the settings area is clearly a vertical list of horizontal widgets, so that suggests they intend to add more than one at some point.
As for the application, itself, this could be useful (especially if other services are added) for users who only stream Blizzard titles, and who want something designed a bit more mainstream than OBS. That said, Raptr and GeForce Experience both fall under this category. Moreover, Blizzard doesn't clarify whether or not the stream will make use of NVIDIA's NVENC, Intel's Quick Sync, or AMD's VCE, all three of which are supported on OBS Studio. Granted, Blizzard titles tend to be easy to compute, but it is hard to beat encoding on an idle, integrated GPU, if you should have one.
That said, choices are good, and you now have another.

Seagate showed off some impressive Solid State Storage at Flash Memory Summit 2016.
First up is the Nytro XM1440. This is a 2TB M.2 22110 SSD complete with enterprise firmware and power loss protection. Nice little package, but what's it for?
..well if you have 60 of them, you can put them into this impressive 1U chassis. This is Facebook's Lightning chassis (discussed yesterday). With Seagate's 2TB parts, this makes for 120TB of flash in a 1U footprint. Great for hyperscale datacenters.
Now onto what you came to see:
This is the 'Seagate 60TB SAS SSD'. It really doesn't need a unique name because that capacity takes care of that for us! This is a 3.5" form factor SAS 12Gbit beast of a drive.
They pulled this density off with a few tricks which I'll walk through. First was the stacking of three PCBs with flash packages on both sides. 80 packages in total.
Next up is Seagate's ONFi fan-out ASIC. This is required because you can only have so many devices connected to a single channel / bus of a given SSD controller. The ASIC acts as a switch for data between the controller and flash dies.
With so much flash present, we could use a bit of fault tolerance. You may recall RAISE from SandForce (who Seagate now owns). This is effectively RAID for flash dies, enabling greater resistance to individual errors across the array.
Finally we have the specs. With a dual 12 Gbit SAS inteface, the 60TB SAS SSD can handle 1.5 GB/s reads, 1.0 GB/s writes, and offers 150,000 IOPS at 4KB QD32 random (SAS tops out at QD32). The idea behind drives like these is to cram as much storage into the smallest space possible, and this is certainly a step in the right direction.
We also saw the XP7200 add-in card. I found this one interesting as it is a PCIe 3.0 x16 card with four M.2 PCIe 3.0 x4 SSDs installed, but *without* a PLX switch to link them to the host system. This is possible only in server systems supporting PCIe Bifurcation, where the host can recognize that certain sets of lanes are linked to individual components.
More to follow from FMS 2016! Press blast after the break.

Tagged: XPoint, Worm, storage, ssd, RocksDB, Optane, nand, flash, facebook
At their FMS 2016 Keynote, Facebook gave us some details on the various storage technologies that fuel their massive operation:
In the four corners above, they covered the full spectrum of storing bits. From NVMe to Lightning (huge racks of flash (JBOF)), to AVA (quad M.2 22110 NVMe SSDs), to the new kid on the block, WORM storage. WORM stands for Write Once Read Many, and as you might imagine, Facebook has lots of archival data that they would like to be able to read quickly, so this sort of storage fits the bill nicely. How do you pull off massive capacity in flash devices? QLC. Forget MLC or TLC, QLC stores four bits per cell, meaning there are 16 individual voltage states for each cell. This requires extremely precise writing techniques and reads must appropriately compensate for cell drift over time, and while this was a near impossibility with planar NAND, 3D NAND has more volume to store those electrons. This means one can trade the endurance gains of 3D NAND for higher bit density, ultimately enabling SSDs upwards of ~100TB in capacity. The catch is that they are rated at only ~150 write cycles. This is fine for archival storage requiring WORM workloads, and you still maintain NAND speeds when it comes to reading that data later on, meaning that decade old Facebook post will appear in your browser just as quickly as the one you posted ten minutes ago.
Next up was a look at some preliminary Intel Optane SSD results using RocksDB. Compared to a P3600, the prototype Optane part offers impressive gains in Facebook's real-world workload. Throughput jumped by 3x, and latency reduced to 1/10th of its previous value. These are impressive gains given this fairly heavy mixed workload.
More to follow from FMS 2016!

As expected, Facebook has added some questionable features to the Oculus Rift and if any of it surprises you then you haven't been paying attention. The Register went through it to pull out a variety of terms than many may find questionable. Your usage will be tracked while you are using the headset and just like Facebook and many other social media apps it will use the data collected for targeted advertising. There does not seem to be any incognito mode, so think twice before using the Rift for certain applications unless you want some interesting adverts showing up on your Facebook page.
A Slashdot post points out a different concern for content creators, if you use the Oculus to create something original then while Oculus can't claim to own it, it can use it without your consent and without having to pay you for for using it. Again, this should not be surprising but if you weren't aware of the possibility, you should consider these T&C's before picking the Rift.
"THOSE OF a weak disposition should look away. News has reached us that face fun virtual reality machine, and eye of Facebook, the Oculus Rift has features that track things that people do, and use the information for the purposes of advertising."

Who would have thought that John Carmack would have opened the flood gates of talent to Facebook. Apparently, not only was he the first in a long list of people to join Oculus, a large chunk of his coworkers at id Software followed him over (if a Glassdoor review is to be trusted) in Februrary. Their latest grab is Adrian Wong, former senior hardware engineer for Google's Glass Explorer program.
Didn't see that one coming...
Clearly, something is happening at Oculus VR. This acquisition by Facebook is giving them a warchest to grab as much top talent as possible. Ironically, without Oculus, I doubt that most of these hires, if any, would happen. Without knowing the internal structure of Facebook and Oculus, it is hard to predict how much benefit the parent company can gather, but the acquisition could be paying for itself in raw talent.
The Oculus Rift DK2, announced at GDC, is currently a $350.00 pre-order and expected to ship in August.
