The Raspberry Pi makes for a cheap and low power media PC, file server, or desktop but the lack of a display means that it is not very portable. Recently a hack was posted online by Max Ogden that enables the Rasbperry Pi to be used on the go by pairing it with an Amazon Kindle and its e-ink display. His wireless display setup was actually based on a previous hack that allowed the Pi to be paired with the 3rd-generation Kindle. Ogden's hack takes things a step further by supporting the latest Paperwhite versions as well as no longer requirig a wired connnection between the display and the Raspberry Pi.
By loading the Raspberry Pi with Raspian Linux and adding a terminal emulator to the Kindle, the Kindle connects to the Pi over an SSH session where the Pi console and any keyboard input can be seen on the Kindle's e-ink display. The hardware needed to make the setup work includes a Wi-Fi hotspot, a Wi-Fi USB NIC, The Raspberry Pi, a supported Kindle, and a battery pack with enough juice to power everything. A wired or wireless keyboard and Wi-Fi dongle can be added to the Raspberry Pi Model B, bu Model A users will need to add a USB hub as the $25 model only supports a single USB port on the device itself.
Max Ogden shows off his new portable battery-powered Raspberry Pi with wireless e-ink display.
There are some limitations to this setup. One is a bit of latency between typing and seeing the characters appear on the screen due to the low refresh rate inherent in e-ink displays and the wireless connection. Ogden estimates that this delay is around 200ms, and is noticeably but bearable while typing. The other major limitation is that the display can currently only be used to display the Pi console, and not the GUI of Raspian. For writing code or articles, you could get by with a command-line text editor like nano or vi--at the very least it would be a distraction-free writing environment as you could not procrastinate and browse Reddit or watch videos even if you wanted to (heh).
If you are interested in setting up your own wireless Raspberry Pi display, you should check out Ogdens blog for a list of recommended hardware as well as Rod Vagg's tutorial on configuring the Kindle Paperwhite with the correct software.
This is one of the more-useful Raspberry Pi hacks that I've seen so far. Hopefully, a future hack will come along that will also allow one of these e-ink devices to display the GUI desktop environment and not just the terminal.

Tagged: gpu, DRAM, ddr3, price increase
It has taken a while but the climbing price of memory is about to have an effect on the price you pay for your next GPU. DigiTimes does specifically mention DDR3 but as both GDDR4 and GDDR5 are based off of DDR3 they will suffer the same price increases. You can expect to see the new prices last as part of the reason for the increase in the price of RAM is the decrease in sales volume. AMD may be hit harder overall than NVIDIA as they tend to put more memory on their cards and buyers of value cards might see the biggest percentage increase as those cards still sport 1GB or more of memory.
"Since DDR3 memory prices have recently risen by more than 10%, the sources believe the graphics cards are unlikely to see their prices return to previous levels within the next six months unless GPU makers decide to offer promotions for specific models or launch next-generation products."

Futuremark recently unveiled its latest 3DMark benchmarking suite for Android devices. Compatible with over 1,000 devices, the new 3DMark is a free benchmark that incorporates both the Ice Storm and Ice Storm Extreme tests. The benchmark was developed by Futuremark in cooperation with a number of industry companies including Broadcom, Imagination Technologies, Intel, NVIDIA, and Qualcomm. The Ice Storm Extreme test is also coming to the Windows version of 3DMark, and the tests can be used to compare benchmark scores across platforms.
Both the benchmarking tests are based on OpenGL ES 2.0. Ice Storm runs through two graphical tests to stress the GPU and one physics test to measure CPU performance. The ice Storm Extreme benchmark takes things further by bumping up the resolution to 1080 and swapping in higher quality textures and post processing effects.
The benchmark is compatible with a number of mobile smartphones and tablets running Android 3.1 or higher. It is a free download from the Google Play store.
The iOS and Windows RT versions of 3DMark are still in development. More information can be found in the press release.

Tagged: arm, FinFET, 16nm, TSMC, Cortex-A57
While what DigiTimes is reporting on is only the first tape out, it is still very interesting to see TSMC hitting 16nm process testing and doing it with the 3D transistor technology we have come to know as FinFET. It was a 64-bit ARM Cortex-A57 chip that was created using this process, unfortunately we did not get much information about what comprised the chip apart from the slide you can see below.
As it can be inferred by the mention that it can run alongside big.LITTLE chips it will not be of the same architecture, nor will it be confined to cellphones. This does help reinforce TSMC's position in the market for keeping up with the latest fabrication trends and another solid ARM contract will also keep the beancounters occupied. You can't expect to see these chips immediately but this is a solid step towards an new process being mastered by TSMC.
"The achievement is the first milestone in the collaboration between ARM and TSMC to jointly optimize the 64-bit ARMv8 processor series on TSMC FinFET process technologies, the companies said. The pair has teamed up to produce Cortex-A57 processors and libraries to support early customer implementations on 16nm FinFET for ARM-based SoCs."

Tagged: lga 2011, Ivy Bridge-E, Intel, 22nm
Many enthusiasts have been eagerly awaiting the next generation of Intel processors to use LGA 2011, which is supposed to be Ivy Bridge-E. Especially after seeing rumors of a 10 core Xeon E5-2600 V2 Ivy Bridge-EP CPU, I think many users expected at least an eight core Ivy Bridge-E part.
Unfortunately, if a slide posted by VR-Zone China is any indication, LGA 2011 users will not be getting an eight core processor any time soon. The slide suggests that Intel will release three new Ivy Bridge-E CPUs in the third quarter of this year (Q3'13). However, the top-end part is merely a six core CPU with slight improvements over the existing Sandy Bridge-E 3960X chip.
Specifically, the slide alleges that the initial Intel release will include the Core i7 4820, Core i7 4930K, and the Core i7 4960X. An Ivy Bridge-E equivalent to the SB-E 3970X is noticeably absent from the lineup along with several of the other rumored (higher core count) chips.
Rumored Ivy Bridge-E chips:
|Clockspeed||Core Count||L3 Cache||Manufacturing Process||TDP|
|Core i7 4960X||3.6GHz (4GHz Turbo)||6||15MB||22nm||130W|
|Core i7 4930K||3.4GHz (3.9GHz Turbo)||6||12MB||22||130W|
|Core i7 4820K||3.7GHz (3.9GHz Turbo)||4||10MB||22||130W|
Existing Sandy Bridge-E equivalents:
|Clockspeed||Core Count||L3 Cache||Manufacturing Process||TDP|
|Core i7 3960X||3.3GHz (3.9GHz Turbo)||6||15MB||32nm||130W|
|Core i7 3930K||3.2GHz (3.8GHz Turbo)||6||12MB||32nm||130W|
|Core i7 3820||3.6GHz (3.8GHz Turbo)||4||10MB||32nm||130W|
All of the chips allegedly have 130W TDPs, 40 PCI-E 3.0 lanes, support for quad-channel DDR3-1866 memory, and are built on Intel's 22nm manufacturing process. The low end i7 4820 is a quad core chip clocked at 3.7 GHz base and 3.9 GHz turbo with 10MB L3 cache. The i7 4930K is an unlocked six core part with 12MB L3 cache and clockspeeds of 3.4 GHz base and 3.9 GHz turbo. Finally, the Core i7 4960X is rumored to be the highest-end chip Intel will release (at least, initially). It is also a six core part clocked at 3.6 GHz base and 4 GHz turbo. It has 15MB of L3 cache. These chips are the Ivy Bridge-E equivalents to the 3820, 3930K, and 3960X chips respectively. The new processors feature higher clockspeeds, and are based on 22nm 3D transistor technology instead of SB-E's 32nm manufacturing process. It seems that Intel has extended unlocking to the lower-tier LGA 2011 chip, as it is listed as the Core i7 4820K. Having an unlocked multiplier is nice to see at the low end (the low end of the enthusiast platform, anyway). Curiously, the TDP ratings are the same, however. That suggests that the move to 22nm did not net Intel much TDP headroom, and the higher clocks are bringing them up to similar TDP numbers. At least the TDP ratings are not higher than SB-E, such that you motherboard and HSF should have no problems accepting an IVB-E CPU upgrade (with a BIOS update, of course).
It will be interesting to see how the new Ivy Bridge-E chips stack up, especially considering Intel may also be unveiling the consumer-grade Haswell processor this year. On one hand, Ivy Bridge-E offers up a CPU upgrade path for existing systems, but on the other hand pricing and the performance of Haswell (and lack of higher core count Ivy Bridge-E chips like previous rumors suggested) may see enthusiasts instead opt for a motherboard+CPU overhaul instead of simply recycling the LGA 2011/X79 motherboard. At this point, if this new slide holds true it appears that Ivy Bridge E/LGA 2011 will become even more of a niche solely for workstations that need the extra PCI-E lanes and quad channel memory. I say this as someone running a Lynnfield system who is itching for an upgrade and torn on going for the enthusiast platform or waiting for Haswell.
What do you think about the rumored Ivy Bridge-E chips, are they what you expected? Do you think they will be worth a CPU upgrade for your LGA 2011-based system or are you leaning towards Haswell?

Tagged: x86 emulator, rpix86, Raspberry Pi, gaming, dos
The Raspberry Pi is proving to be a popular destination for all manner of interesting software projects and open source operating systems. The most-recent Pi project I've come across is a DOS PC emulator by Patrick Aalto called rpix86. A port of DSx86, which ran on the Nintendo DS handheld console, rpix86 is now up to version 0.04 and emulates a 90's X86 computer with enough hardware oomph to run classic PC games!
Rpix86 is an emulator that runs from the console (not within the X GUI desktop environment) on the Raspberry Pi. It emulates the following X86 PC specs:
|Processor||80486 @ ~ 20 MHz (inc. protected mode. No virtual memory support)|
|Memory||640 Kb low memory, 4 MB EMS memory, 16 MB XMS memory|
|Graphics||Super VGA @ 640 x 480 w/ 256 colors|
|Audio||Sound Blaster 2.0 (+ AdLib-compatible FM sounds)|
|Input Devices||US keyboard, analog joystick, 2 button mouse|
|Misc||Roland MPU-401 MIDI Support via USB MIDI Dongle|
Patrick Aalto added support for analog USB joysticks and foot pedals (4 buttons, 4 analog channels) as well as 80 x 50 text mode (required by some MIDI software and Little Big Adventure's setup program) to the recent 0.04 update. He also stripped out debug code, which cut the program size approximately in half.
The developer has stated on his blog that he is working on allowing rpix86 to be used from the terminal within X and adding support for intelligent MPU MIDI mode. A port to the Android operating system called ax86 is also in the works. You can grab the current version of the Raspberry Pi X86 emulator on the developer's website.
With this emulator, you can run most of the DOS games you grew up with (Wolf3D and Digger anyone?), which is definitely a worthy use for the $25 or $35 Raspberry Pi hardware! At the very least, it is an interesting alternative to running DOSBox, and much smaller and more power efficient than running an old X86 PC dedicated to running classic games. Getting those floppies to work with the Pi might be a bit of an issue though, assuming they are still readable (heh).

Tagged: file sync, cloud storage, cloud drive, amazon
Amazon has announced two new Java-based applications for Windows and Mac PCs that will sync files between multiple computers and the company's Cloud Drive online storage service.
Amazon Cloud Drive is a companion service that was spun off of its Cloud Player music locker service. Users get 5GB for free, with additional tiers of storage available for purchase. (Any music from Amazon side-loaded to Cloud Drive and Cloud Player before July 31st does not count towards your storage quota). Until now, Cloud Drive has been merely a web storage locker, but with the new desktop apps Amazon is adding file syncing capabilities that will keep your files updated across multiple PCs. The desktop apps will create a folder which will then contain a locally-stored copy of your Amazon Cloud Drive files. If you choose to install the desktop app onto a second PC, it will also sync with Cloud Drive and store a copy of the files locally. The most recently modified version will sync to all the other computers' local store and the cloud drive. There is no word on versioning support, so note that this should not be a replacement for a true file backup. With that said, the multiple-PC file sync is a welcome addition that makes Cloud Drive much more useful than ever before.
The new desktop apps will run on Windows XP, Vista, 7, and 8, and on Mac OS X 10.6, 10.7, and 10.8.
When Amazon was asked about mobile apps and file sync, the company told Ars Technica that it had "nothing specific to share." That could mean that Cloud Drive will bring file synchronization to iOS, Android, and WP8, or it could be a literal statement. It is difficult to say, but I think if Amazon wants its Cloud Drive storage service to be taken seriously the company will need to enter the mobile space (as it has done with Cloud Player).

Tagged: next generation character rendering, GDC 13, gaming, Activision, 3D rendering
Activision recently showed off its Next-Generation Character Rendering technology, which is a new method for rendering realistic and high-quality 3D faces. The technology has been in the works for some time now, and is now at a point where faces are extremely detailed down to pores, freckles, wrinkles, and eye lashes.
In addition to Lauren, Activision also showed off its own take on the face used in NVIDIA's Ira FaceWorks tech demo. Except instead of the NVIDIA rendering, the face was done using Activision's own Next-Generation Character Rendering technology. A method that is allegedly more efficient and "completely different" than the one used for Ira. In a video showing off the technology (embedded below), the Activision method produces some impressive 3D renders in real time, but when talking appear to be a bit creepy-looking and unnatural. Perhaps Activision and NVIDIA should find a way to combine the emotional improvements of Ira with the graphical prowess of NGCR (and while we are making a wish list, I might as well add TressFX support... heh).
The high resolution faces are not quite ready for the next Call of Duty, but the research team has managed to get models to render at 180 FPS on a PC running a single GTX 680 graphics card. That is not enough to implement the technology in a game, where there are multiple models, the environment, physics, AI, and all manner of other calculations to deal with and present at acceptable frame rates, but it is nice to see this kind of future-looking work being done now. Perhaps in a few graphics card generations the hardware will catch up to the face rendering technology that Activision (and others) are working on, which will be rather satisfying to see. It is amazing how far the graphics world has come since I got into PC gaming with Wolfenstein 3D, to say the least!
The team behind Activision's Next-Generation Character Rendering technology includes:
|Javier Von Der Pahlen||Director of Research and Development|
|Etienne Donvoye||Technical Director|
|Bernardo Antoniazzi||Technical Art Director|
|Zbyněk Kysela||Modeler and Texture Artist|
|Mike Eheler||Programming and Support|
|Jorge Jimenez||Real-Time Graphics Research and Development|
Jorge Jimenez has posted several more screenshots of the GDC tech demo on his blog that are worth checking out if you are interested in the new rendering tech.

Tagged: virtual reality, oculus vr, oculus rift, GTC 2013, gaming
Update: Yesterday, an Oculus representative reached out to us in order to clarify that the information presented was forward looking and subject to change (naturally). Later in the day, the company also posted to its forum the following statement:
"The information from that presentation (dates, concepts, projections, etc...) represent our vision, ideas, and on-going research/exploration. None of it should be considered fact, though we'd love to have that projected revenue!"
You can find the full statement in this thread.
The original article text is below:
Oculus VR, the company behind the Oculus Rift virtual reality headset, took the stage at NVIDIA's GPU Technology Conference to talk about the state of its technology and where it is headed.
Oculus VR is a relatively new company founded by Palmer Luckey and managed by CEO Brendan Iribe, who is the former CPO of cloud gaming company Gaikai. Currently, Oculus VR is developing a wearable, 3D, virtual reality headset called the Oculus Rift. Initially launched via Kickstarter, the Oculus Rift hardware is now shipping to developers as the rev 1 developer kit. Oculus VR will manufacture 10,000 developer kits and managed to raise $2.55 million in 2012.
The developer kit has a resolution of 1280x800 and weighs 320g. It takes a digital video input via a DVI or HDMI cable (HDMI with an adapter). The goggles hold the display and internals, and a control box connects via a wire to provide power. It uses several pieces of hardware found in smartphones, and CEO Brendan Iribe even hinted that an ongoing theme at Oculus VR was that "if it's not in a cell phone, it's not in Oculus." It delivers a 3D experience with head tracking, but Iribe indicated that full motion VR is coming in the future. For now, it is head tracking that allows you to look around the game world, but "in five to seven or eight years" virtual reality setups that combine an Oculus Rift-like headset with a omni-directional treadmill would allow you to walk and run around the world in addition to simply looking around.
Beyond the immersion factor, a full motion VR setup would reduce (and possibly eliminate) the phenomena of VR sickness, where users using VR headsets for extended periods of time experience discomfort due to the disconnect between your perceived in-game movement and your (lack of) physical movement and inner-ear balance.
After the first developer kit, Oculus is planning to release a revised version, and ultimately a consumer version. This consumer version is slated for a Q3 2014 launch. It will weigh significantly less (Oculus VR is aiming for around 200g), and will support 1080p 3D resolutions. The sales projections estimate 50,000 revision 2 developer kits in 2013 and at least 500,000 consumer versions of the Oculus Rift in 2014. Ambitious numbers, for sure, but if Oculus can nail down next-generation console support, reduce the weight of the headset, and increase the resolution it is not out of the question.
With the consumer version, Oculus is hoping to offer both a base wired version and a higher-priced wireless Rift VR headset. Further, the company is working with game and professional 3D creation software developers to get software support for the VR headset. Team Fortress 2 support has been announced, for example (and there will even be an Oculus Rift hat, for gamers that are into hats). Additionally, Oculus is working to get support into the following software titles (among others):
- AutoDesk 3D
- DOTA 2
During the presentation Iribe stated that graphics cards (specifically he mentioned the GTX 680) are finally in a place to deliver 3D with smooth frame rates at high-enough resolutions for immersive virtual reality.
Left: potential games with Oculus VR support. Right: Oculus VR CEO Brendan Iribe at ECS during GTC 2013.
Pricing on the consumer version of the VR headset is still unkown, but developers can currently pre-order an Oculus Rift developer kit on the Oculus VR site. In the past, the company has stated that consumers should hold off on buying a developer kit and wait for the consumer version of the Rift in 2014. If the company is able to deliver on its claims of a lighter headset with higher resolution screen and adjustable 3D effects (like the 3DS, the level of stereo 3D can be adjusted, and even turned off), I think it will be worth the wait. The deciding factor will then be software support. Hopefully developers will take to the VR technology and offer up support for it in upcoming titles into the future.
Are you excited for the Oculus Rift?
