Tagged: DIY, self driving car, comma.ai, geohot
George Hotz, aka [Geohot], created the comma.ai program in an effort to create and sell a program to control self driving cars. The US National Highway Traffic Safety Administration took offence to this, citing the possibility of this endangering humans in a letter sent to his company Comma.Ai. He shut down the project rather than having to deal with lawyers, red tape and regulations. The code survived however and is now available on GitHub. Hack a Day took a look and discovered it is written in Python with some C included and is rather easy to interpret if you are familiar with the language. It is compatible with Acura ILXs or Honda Civic 2016 Touring models, if you are so inclined.
"First there was [Geohot]’s lofty goal to build a hacker’s version of the self-driving car. Then came comma.ai and a whole bunch of venture capital. After that, a letter from the Feds and a hasty retreat from the business end of things. The latest development? comma.ai’s openpilot project shows up on GitHub!"

Tagged: Intel, z270, h270, intel z270, kaby lake, Optane, PCI-E 3.0
Details on Intel’s upcoming Z270 and H270 chipsets surfaced last month that fleshed out the new platform and its capabilities including the inclusion of additional PCI-E 3.0 lanes and out-of-the-box support for 7th Generation Intel Kaby Lake processors versus the current generation Z170 and H170 chipsets.
An alleged Z270 motherboard from ASUS (STRIX Z270G GAMING) per Wccftech.
TechPowerUp reported that Intel’s 200-series chipsets – which would be used on motherboards with the LGA 1151 socket – would feature incremental improvements over their current generation equivalents including the upgrade to Intel Rapid Storage Technology (RST) version 15, support for Intel Optane Technology, and additional downstream PCI-E 3.0 lanes. The Z270 and H270 chipsets each have four extra lanes compared to their 100-series predecessors. These “downstream lanes” allow for additional high bandwidth connections that hang off the chipset (which does appear to still be ultimately limited by the physical four PCI-E 3.0 lanes that make up the DMI 3.0 link between the CPU and PCH). Examples include extra Thunderbolt, USB 3.1, and PCI-E slots for NICs, capture cards, storage controllers, or even graphics cards.
Intel Z270 Express will feature 14 general purpose PCI-E lanes versus 10 on Z170 Express along with a total lane budget of 30 versus 26 (16 of those lanes are reserved for CPU to one or two PCI-E 3.0 x16 slots (electrically 1x16 or 2x8) and the others come from the chipset but really connect back to the CPU over a DMI 3.0 link that is equivalent to four lanes of PCI-E 3.0. H270 also features 14 general purpose lanes versus what appears to be six on H170. H270 and H170 have 16 PCI-E 3.0 lanes coming from the CPU for graphics so it is a total lane budget of 30 versus 22 respectively.
|High Speed IO (HSIO)||30||26||30||22|
|PCI-E 3.0 Lanes||24||20||20||16|
|Maximum M.2 slots||3||3||2||2|
H270 will see the biggest benefit from the additional PCI-E lanes which could mean systems like HTPCs and budget desktops where overclocking and multi-GPU setups are not a concern using H270 chipset motherboards could still support a full range of external IO and fast storage.
One interesting thing I noticed from the table is that Z270 and H270 do not support additional M.2 slots. The maximum number of M.2 slots remains the same as their 100-series counterparts at three and two respectively. After talking with Allyn, this makes sense because of that limiting factor that is the four lane DMI 3.0 link to the CPU and memory. Specifically, he explained:
“Think of the chipset as a means of fanout to individual things that won't simultaneously consumer more than x4. You can use the extra lanes for other stuff, like additional USB 3.1 controllers, Ethernet, audio, etc. Heck, you can route them to the last PCIe slot if you wanted.”
Further, Intel will continue to differentiate the Z270 Express and H270 Express by supporting multiplier overclocking and multi-GPU setups solely on Z270-based motherboards. H270 will be single x16 slot boards that do not allow multiplier-based overclocking at best and more than likely any CPU overclocking. The tradeoff being that H270-based boards should be much cheaper.
Intel Optane support is compelling, but will not be a reason to upgrade quite yet as drives are still a ways off and when they do arrive are sure to be very expensive. Rumors do suggest that Intel may introduce a small 3D XPoint-based Optane SSD up to 32GB alongside the rollout of Kaby Lake and new motherboards but as that is not large enough for an OS drive it will remain more of a niche thing at first. As larger drives come out at lower price points, the support for them on Z270 and H270 would help make the case for enthusiasts running Z170 and H170 boards to make the jump.
Of course, that brings me to my main thought surrounding Z270 and H270 based motherboards which is that while someone looking to build a new PC could justify going straight to the newer chipset-based motherboards, users running existing Z170 and H170 motherboards – many of which will support Kaby Lake processors with a BIOS update – have little reason to jump at an upgrade. Budget builds might even justify going to the older and cheaper boards if they don’t need the new features and putting the saved money towards something like more memory or a better CPU cooler.
For the highest end (save HEDT) builds, Z270-based boards should offer more connectivity options for Thunderbolt and USB 3.1 ports and the ability to dive into XPoint storage when it fully rolls out is nice. There are arguments to be main on both sides.
What are your plans for Kaby Lake? Will you be upgrading to the new processor, and if so will be using a Z170/H170 or a new Z270/H270 board?

Tagged: watercooling, tower 900, thermaltake, liquid cooling, E-ATX Case, case mods
Thermaltake is readying the Tower 900 for launch later this month. Clad in all-black or snow white, the Tower 900 was designed in concert with Watermod France to be modder and liquid cooling friendly with a design that allows enthusiasts to show off their DIY builds.
The upcoming Tower 900 series is part of Thermaltake’s TT Premium line and is constructed using a “dismantlable module design” that allows builder to completely strip the case down to the frame to make modding the various panels and pants easier. The case used a neat dual chamber design that puts the PC components front and center and the liquid cooling, power supply, and storage devices behind the motherboard chamber.
The front chamber is surrounded on three sides by 5mm thick tempered glass and holds up to E-ATX motherboards vertically and supports 260mm high CPU coolers and 400mm long graphics cards. There are 8 PCI expansion slots. In addition to the motherboard, the front chamber holds two 3.5”/2.5" drive trays that are visible through the case windows, two hidden 2.5" SSD mounts, and up to two large coolant reservoirs. Thermaltake suggests that the Tower 900 would work well with dual loop systems, and I tend to agree. Modders will be able to put together some very nice looking builds, especially if they use rigid tubing.
Other features include large rounded case feet, a single 5.25” drive bay nestled in the bottom of the front panel, and four USB 3.0 and one audio jack for front panel I/O up top.
Around back, the Tower 900 hosts a standard ATX power supply, up to four 3.5” or 2.5” drives in a hard drive cage (though you give up some radiator capacity on the right side if you use the HDD cage), and up to an impressive 480mm or 560mm (depending on if its 120mm or 140mm fans) radiator on both the left and right sides! In theory you could have a 560mm radiator for your multi GPU setup on one loop and 360mm radiator for the CPU on a second loop along with all four hard drives or if you can get by with the two 2.5” drives in the front chamber your CPU could also have a 480/560mm radiator of its own.
If you are into air cooling, the Tower 900 supports a total of 13 120mm or 140mm fans. One fan in the front chamber above the SSD drive trays, four on the left, four and four on the right in the back chamber, and two fans each on the top and bottom.
For those curious, the case measures 29.6” x 16.7” x 19” and weighs 54 pounds. Once it is full of water and PC components, you should probably team lift this monster heh. Additional photos and videos can be found here.
It certainly looks nice, and I can see a lot of potential for custom PCs. I am looking forward to seeing the full reviews as well as what enthusiasts are able to do with it!

Tagged: VR, razer, osvr, Khronos
The Khronos Group is the standards body that maintains OpenGL, Vulkan, OpenCL, along with several other APIs and formats. They are made up of several members, which include companies of various sizes along with educational institutions, with a couple of tiers where members of the higher level, Promoter, get board nomination rights.
The lower level, Contributor, has just received a new member: Razer. The Khronos Group published a little statement to their front page, but didn’t provide a way to permanently link it and the Read More just directs to Razer’s homepage. Also, Razer didn’t provide a press release on their website, at least by the time this news was published, so I included the statement below to prevent it from getting buried in a few days:
The Khronos Group is proud to announce that Razer has joined as a Contributor Member. Razer is a world leader in connected devices and software for gamers. Its award-winning design and technology span systems, peripherals, audio and wearable technologies. Razer co-founded OSVR, an open-source platform that integrates VR, AR and mixed reality hardware and software APIs that support a universal VR ecosystem.
Based on this, it’s easy to speculate that Razer is looking to have a say and a vote in how graphics APIs evolve, nudging it as needed for OSVR, their co-founded virtual reality platform. Basically every other VR developer worth mentioning is already a member, including Google, Microsoft, Oculus VR, Samsung, Sony, and Valve. Likewise, Vulkan is undergoing rapid development, and the next version, codenamed Vulkan Next, has VR as one of its “top priorities”. It seems like a good time for Razer to get involved.
Otherwise? Not much to speak of here. Razer is a fairly big company that wants to be active in technology development, and it can easily afford the Khronos Group membership fee. I mean, the amount they spent on USB ports with a specific shade of green would cover about twenty years of membership to the Khronos Group, so it seems within their reach.

Tagged: gaming mouse, input, dream machines, DM Pro S
The Dream Machines DM1 PRO S gaming mouse uses a Pixart PMW 3360 optical sensor, not one commonly utilized in the market. The DPI of the sensor can be toggled in set increments from 400 up to 12000, with the colour of the light under the logo indicating your current setting; the lack of software precludes manipulation of those presets. The overall design of the mouse looks ambidextrous, however there are only thumb buttons on the left side of the mouse. TechPowerUp were very impressed with the performance of the new sensor, as to the rest of the features you will just have to pop over and read them yourself.
"A few months ago, we reviewed the Dream Machines DM1 PRO, and Dream Machines is now back with the DM1 PRO S. This version has an updated sensor, has been slimmed down to be even lighter, and has a rather nice glossy finish. Improvements, which could be a game changer."

Tagged: kaby lake, Intel, core i7 7700k
Someone, who wasn’t Intel, seeded Tom’s Hardware an Intel Core i7-7700k, which is expected for release in the new year. This is the top end of the mainstream SKUs, bringing four cores (eight threads) to 4.2 GHz base, 4.5 GHz boost. Using a motherboard built around the Z170 chipset, they were able to clock the CPU up to 4.8 GHz, which is a little over 4% higher than the Skylake-based Core i7-6700k maximum overclock on the same board.
Image Credit: Tom's Hardware
Lucky number i7-77.
Before we continue, these results are based on a single sample. (Update: @7:01pm -- Also, the motherboard they used has some known overclock and stability issues. They mentioned it a bit in the post, like why their BCLK is 99.65MHz, but I forgot to highlight it here. Thankfully, Allyn caught it in the first ten minutes.) This sample has retail branding, but Intel would not confirm that it performs like they expect a retail SKU would. Normally, pre-release products are labeled as such, but there’s no way to tell if this one part is some exception. Beyond concerns that it might be slightly different from what consumers will eventually receive, there is also a huge variation in overclocking performance due to binning. With a sample size of one, we cannot tell whether this chip has an abnormally high, or an abnormally low, defect count, which affects both power and maximum frequency.
That aside, if this chip is representative of Kaby Lake performance, users should expect an increase in headroom for clock rates, but it will come at the cost of increased power consumption. In fact, Tom’s Hardware states that the chip “acts like an overclocked i7-6700K”. Based on this, it seems like, unless they want an extra 4 PCIe lanes on Z270, Kaby Lake’s performance might already be achievable for users with a lucky Skylake.
I should note that Tom’s Hardware didn’t benchmark the iGPU. I don’t really see it used for much more than video encoding anyway, but it would be nice to see if Intel improved in that area, seeing as how they incremented the model number. Then again, even users who are concerned about that will probably be better off just adding a second, discrete GPU anyway.

Depending on which model you order, the MSI Aegis Ti PC will have an i7-6700K or i5-6600K and a pair of either GTX 1080s or 1070s. The model which shipped to TechPowerUp for testing sported a pair of M.2 Samsung 950 PROs and 32GB of DDR4-2400, along with the i7-6700K and GTX 1080s of course. The unique looking enclosure is VR Ready, in that there are USB and HDMI ports in the front to let you easily attach your VR goggles and is more than powerful enough to power said device at high settings. If you would prefer to spend $3000 on a configured gaming rig with some interesting features as opposed to building one yourself, pop over for a look at the full review.
"MSI sent us their latest fully featured PC, the Aegis Ti, to take a look at. This PC departs from the "traditional box" design in a big way and is ready to support not just one but two GTX 1080s! It's VR ready, including an HDMI port in front and dual M.2 drives, which can be configured in RAID, making it ready for whatever you want to throw at it."

Tagged: serious sam vr, nvidia, gaming, pascal
Having already looked at AMD's performance with two RX 480's in a system, the recent patch which enables support for multiple NVIDIA GPUs have dragged [H]ard|OCP back into the game. Lacking a pair of Titan X cards, they tested the performance of a pair of GTX 1080s and 1070s; the GTX 1060 will not be receiving support from Croteam. It would seem that adding a second Pascal card to your system will benefit you, however the scaling they saw was nowhere near as impressive as with the AMD RX 480 which saw a 36% boost. Check out the full results here and yes ... in this case the m in mGPU indicates multiple GPUs, not mobile.
"Serious Sam VR was the first commercial enthusiast gaming title to include multi-GPU support with AMD's RX 480 GPU. Now the folks at Croteam have added mGPU support for NVIDIA cards as well. We take a look at how well NVIDIA's VRSLI technology fares in this VR shooter title."

Is Bitlocker cramping your voyeuristic cravings and preventing you from snooping on your loved ones or strangers? Assuming you do not instead seek medical help for your problem, all you need to do is wait for Windows to perform a version update and for the user to get bored and walk away. Hop onto their machine and press SHIFT+F10 to get a command prompt which will be running at root privileges and take advantage of the fact that Windows disables Bitlocker while installing an updated version of Windows. This will not work for all updates, it needs to be a major OS update such as the move to Anniversary Edition which changes the version of Windows installed on the machine.
Microsoft is working on a fix, in the meantime sticking with Windows Long Term Service Branch or slighly modifying how updates are pushed via WSUS or SCCM will ensure this vulnerability cannot be leveraged. You can also take the simple measure of sticking around when major updates occur. Pop over to Slashdot for more information.
"This [update procedure] has a feature for troubleshooting that allows you to press SHIFT + F10 to get a Command Prompt," Laiho writes on his blog. "The real issue here is the Elevation of Privilege that takes a non-admin to SYSTEM (the root of Windows) even on a BitLocker (Microsoft's hard disk encryption) protected machine." Laiho informed Microsoft of the issue and the company is apparently working on a fix."

Tagged: nasbook, NAS, qnap, TBS-453A
Network Attached Storage is nothing new, but a NASbook certainly is. When you think of a NAS device you might picture a box with at least two network connections and limited controls on the device with a web based GUI. QNAP have created something very different in the TBS-453A, a NAS in a notebook-like form factor with a lot of extra functionality. You will find two HDMI v2.0 ports, two 3.5mm microphone jacks and an audio line out as well as a pair of Gigabit Ethernet ports and three gigabit switch ports as it can function as a router, along with a total of four USB 3.0 ports and a single USB 2.0 port. Unfortunately it lacks 10GbE ports which it would benefit from as it hides inside it four M.2 SATA 6Gbps SSDs which can easily overwhelm a gigabit connection, especially if multiple clients are accessing data simultaneously.
Curious what it is capable of and how well it performs? Check out Nikktech's review.
"Although we all like the concept behind the new TBS-453A NASbook by QNAP quite honestly it feels ahead of its time mainly due to the current pricing of M.2 SSDs and lack of one or more 10GbE ports."

The Megaprocessor is a working CPU which is blown up in size to allow you to walk into it to watch how data is physically processed with your own eyes. There are 8,500 LED's in the core and another 2,048 for the memory which light up as data passes through the 15,300 transistors in the core and the memory's 27,000; though that total count includes the transistors which control the LEDs. The core's clock is a staggering 25kHz and there is 256 bytes of both RAM and ROM. The site actually provides you with the assembly language to write code for the processor if you are interested and you can visit the Centre for Computing History in Cambridge, England to see it in person. Drop by The Register for a quick look and for links to the project page for more details on the computer and build process, including a murderous vacuum cleaner.
"His ultimate goal other than the pure satisfaction of building the thing and getting it running, as El Reg reported in June this year, was to show the public how computers work by blowing the CPU up to a human-viewable scale."

Tagged: amd, Zen, Summit Ridge
Guru3D got hold of a product list, which includes entries for AMD’s upcoming Zen architecture.
Four SKUs are thus rumored to exist:
- Zen SR3: (65W, quad-core, eight threads, ~$150 USD)
- Zen SR5: (95W, hexa-core, twelve threads, ~$250 USD)
- Zen SR7: (95W, octo-core, sixteen threads, ~$350 USD)
- Special Zen SR7: (95W, octo-core, sixteen threads, ~$500 USD)
The sheet also states that none of these are supposed to contain integrated graphics, like we see on the current FX line. There is some merit to using integrated GPUs for specific tasks, like processing video while the main GPU is busy or doing a rapid, massively parallel calculation without the latency of memory copies, but AMD is probably right to not waste resources, such as TDP, fighting our current lack of compatible software and viable use cases for these SKUs.
Image Credit: Guru3D
The sheet also contains benchmarks for Cinebench R15. While pre-rendered video is a task that really should be done on GPUs at this point, especially with permissive, strong, open-source projects like Cycles, they do provide a good example of multi-core performance that scales. In this one test, the Summit Ridge 7 CPU ($350) roughly matches the Intel Core i7-6850K ($600), again, according to this one unconfirmed benchmark. It doesn’t list clock rates, but other rumors claim that the top-end chip will be around 3.2 GHz base, 3.5 GHz boost at stock, with manual overclocks exceeding 4 GHz.
These performance figures suggest that Zen will not beat Skylake on single-threaded performance, but it might be close. That might not matter, however. CPUs, these days, are kind-of converging around a certain level of per-thread performance, and are differentiating with core count, price, and features. Unfortunately, there doesn’t seem to have been many leaks regarding enthusiast-level chipsets for Zen, so we don’t know if there will be compelling use cases yet.
Zen is expected early in 2017.

Tagged: amd, graphics drivers
For tomorrow’s Watch_Dogs 2, AMD has released Radeon Software Crimson Edition 16.11.5 graphics drivers, giving users a day to configure their PCs. Note that, while the download links in the release notes say 16.11.4, hovering your mouse over them shows the correct version, dated last Friday. Don’t worry, though, the Radeon Technologies Group is based out of Markham, Ontario, Canada, so they didn’t miss out on turkey leftovers to bring you this software.
Okay, yes, that joke was lame. Moving on.
Beyond Watch_Dogs 2, this driver release also adds a new CrossFire profile for Dishonored 2 for Windows 8.x and Windows 10, so multiple GPU users of that game might want to upgrade, too. Beyond that, flickering in The Division and Battlefield 1 while using CrossFire is also addressed.
There are quite a few known issues, though, including a few crashes when using the Vulkan API. Most of these known issues were present in 16.11.4 from a couple of weeks ago, including the aforementioned Vulkan crashes, but this driver adds two. The CrossFire profile for Dishonored 2 that was added with this driver will be disabled on Windows 7, although it sounds like that will be fixed in a future release. Also, Watch_Dogs 2 may flicker or crash when using Crossfire with two RX 480s, but apparently not other configurations.
The driver is not signed by WHQL, but I think I prefer what AMD’s doing now, rapidly releasing several drivers a month, addressing issues as they arise, versus a Microsoft stamp of approval. All that matters is that they can be installed on Anniversary Edition clean installs with Secure Boot enabled, and they can.

Because holiday shopping is... wrapping up... this year’s rush of AAA games will be slowing down soon, at least until it starts up again in January. One of the last releases, Watch_Dogs 2, will be arriving on the PC tomorrow. As such, NVIDIA has released GeForce 376.09 drivers out to their website and GeForce Experience. The driver also includes optimizations for Dead Rising 4 and Steep.
Unfortunately, the release notes aren’t yet available as of time of this writing (but the link is). As such, we don’t know specifics about what the driver fixes or changes. The notes are supposed to be up at some time today. Users in the forums have been complaining about a few things here and there, but nothing that seems credible and wide-spread that could be attributed to the driver.

In Win are a venerable supplier of PSUs who slowly faded into the background as the PSU market has grown to include numerous manufacturers and resellers. They are looking to get back into the minds of shoppers with their new Classic series, sporting a fully modular design, separated 12V rails, alumumium exteriors and an 80 Plus Platinum rating. Inside the unit you will find Nippon Chemi-con and a clean design which impressed [H]ard|OCP. Looks are not the only important thing when choosing a PSU however, check out the full review to see how well the In Win Classic 750W performed.
"It has been years since we have reviewed a computer power supply from In Win. You might remember the In Win name from being a prolific case supplier back in the early enthusiast days of the 1990's. How does In Win stack up in 2016 with its Classic series PSU that has a very sleek look to it and nice feature set?"

***This is your own personal Netflix seeing as how you are no longer able to access Netflix on "unofficial" devices. Check the comments for great info.**
Over at Linux.com you can find instructions on making a very inexpensive headless Plex Media Server. You will need a working PC to start up the installation by formatting an SD card and setting it up with NOOBS. A little configuration work on the Pi, linking it to your locally stored video libraries and online content such as CNN and Netflix and you have a media centre ready for use, for well under $100. Maybe you could consider making one as a gift for someone deserving. The full instructions and parts list can be found here.
"No, you don’t have to buy an expensive, bulky PC. All you need is a Raspberry Pi 3, a hard drive, an SD card and a mobile charger. It should all cost less than $100."

I was one of the lucky kids who got a Virtual Boy, which was actually quite fun for nine-year-old me. It wasn’t beloved by the masses, but when you’re in a hotel, moving across the country, you best believe I’m going to punch that Teleroboxer cat in the head, over and over. It was quite an interesting piece of technology, despite its crippling flaws.
To see for yourself, Ben Heck published a full disassemble, with his best-guess explanations. He then performs a repair by 3D printing a clamp to put pressure on a loose ribbon connector.
From a performance standpoint, the Virtual Boy was launched with a 32-bit NEC RISC processor, clocked at 20 MHz. Keep in mind that, one, this is a semi-mobile, battery-powered device and, two, it launched around the same time as the original Pentium processor reached 120 MHz. The RAM setup is... unclear. I’m guessing PlanetVB accidentally wrote MB and KB to refer to “megabit” (Mb) and “kilobit” (kb) instead of “megabyte” and “kilobyte”, meaning the Wikipedia listing of 128KB VRAM, 128KB DRAM, and 64KB WRAM is accurate. The cartridge could also address up to an additional 16MB of RAM, meaning that specific titles could load as much as they need, albeit at a higher BOM cost. Shipped titles maxed out at 8KB of cartridge-expanded RAM, though.
Ben Heck’s video will be part of a series, where he will try to make it smaller and head-mounted.
