Microsoft is working on a new way to display the web to you, projecting it onto your walls. They make use of Kinect to map your walls so that they can pick where to beam your content. According to what Microsoft told The Inquirer, they can manage to project sites at 30 frames per second with up to 25 screens and up to a 1440x720 resolution. They make a nod to security concerns, it seems that the information about what your room contains will not be sent back to the website you are viewing.
"Called Surroundweb, the software is peddled by Microsoft as an "immersive room experience". However, as far as we can see, it's simply a means of projecting different parts of a web page on different surfaces around a room."

According to Kara Swisher at Re/code, two of Microsoft's Executive Vice Presidents are leaving the company. Tony Bates, EVP of Business Development and Evangelism, and Tami Reller, EVP of Marketing, are expected to have their departure announced to the public on Tuesday. Tony Bates joined the company during the Skype acquisition in 2011, while Tami Reller has been with Microsoft since it acquired Great Plains Software in 2001. While Bates is expected to depart immediately, Reller is expected to remain for a while and "help with the transition".

Seeing the Microsoft reorganization, it should be quite obvious how expensive they can become. They are struggling to find a path for their products that their customers actually want to go down. At the same time, people seem to be flying in every direction. I just wonder if these are the final movements.

The NVIDIA GeForce GTX 750 Ti is fast but also power efficient, enough-so that Ryan found it a worthwhile upgrade for cheap desktops with cheap power supplies that were never intended for discrete graphics. Of course, this recommendation is about making the best of what you got; better options probably exist if you are building a PC (or getting one built by a friend or a computer store).

Tom's Hardware went another route: make it fanless.
After wrecking a passively-cooled Radeon HD 7750, which is probably a crime in Texas, they clamped it on to the Maxwell-based GTX 750 Ti. While the cooler was designed for good airflow, they decided to leave it in a completely-enclosed case without fans. Under load, the card reached 80 C within about twenty minutes. The driver backed off performance slightly, 1-3% depending on your frame of reference, but was able to maintain that target temperature.
Now, if only it accepted SLi, this person might be happy.

Passively cooled PCs are an interesting niche, often associated with the need for silence. Be it audio recording or home theater appliances, some situations are just not well suited to having a whirring fan.
Recently announced is the fit-PC4 is a fanless system, fourth in its lineage. This time the system is using AMD for its CPU and GPU. Two models are available, separated into "Pro" and "Value". Its specifications are broken down into the table below.
|fit-PC4 Pro||fit-PC4 Value|
|Processor||AMD GX-420CA (25W TDP, Kabini)||AMD A4-1250 APU (8W TDP, Temash)|
|- CPU||Quad-core (Jaguar-based) @ 2.0 GHz||Dual-core (Jaguar-based) @ 1.0 GHz|
|- GPU||Radeon HD 8400E||Radeon HD 8210|
|RAM||Up to 16GB (2 DIMM)|
|Storage||2.5" HDD/SSD + mSATA + microSD|
2x HDMI 1.4a (1920x1200 max) with CEC support
S/PDIF, line-out, mic-in (I assume 3.5mm)
2x Gigabit Ethernet
mini-PCIe slot for cellular modem
2x USB 3.0 and 6x USB 2.0
|Bluetooth||4.0||3.0 + HS|
|Dimensions||16cm x 19cm x 3.7cm||16cm x 16cm x 2.5cm|
Interestingly, the company considers these devices "ruggedized" as well as fanless. As such, they have a 5-year warranty. It seems to be quite the feature-packed device with two HDMI 1.4 outlets, two Gigabit Ethernet ports, and an available slot for a cellular modem. The Pro even has 802.11ac WiFi. I am not entirely sure the intended purpose of this device, but the company claims that the previous generation product was often purchased by video surveillance and digital signage customers. Interestingly, Windows 7 and Linux are the two choices for operating systems.
The fit-PC4 is available now in either a $299 (Value-Barebone) or $380 (Pro-Barebone) model.

Tagged: corsair, mining
When mining some form of cryptographic coin, very few components in the system are utilized. A GPU is basically a self-contained massively parallel cruncher with its own memory and logic. The host system just needs to batch the tasks which leads to PCs with dirt-cheap CPUs, a very modest amount of RAM, and quite literally a half-dozen high-end graphics cards.
If you thought that gaming machines skew a little too much towards GPUs, you should see a mining rig with five R9 290X cards fed by a Sempron.
As you can guess, since many GPUs are double-slot, it might be difficult to fit seven of them in a seven-slot motherboard with a limited number PCIe lanes. To get around this limitation, miners attach their graphics cards to extension cables. Thankfully (for them), mining does not pass a lot of data across the bus to the host system. Even a single PCIe fails to be a bottleneck, apparently.
Anyway, the Corsair blog created an open-air rack which hangs six graphics cards (five HD 7970s and a R9 290X) above a motherboard housing an Intel Celeron G1830. For air, a quartet of Corsair fans suck air upwards and around the graphics cards. For power, of course they use the Corsair AX1500i because why not mine with an arc welding torch. It apparently had more power capacity than the breaker they originally hooked it up to. Whoops.
While ridiculous, I do hope to see systems with multiple (even mismatched) graphics processors as we move toward batches of general mathematics. PhysX was not entirely successful in teaching users that GPUs do not need to be in SLi or Crossfire configurations to load balance. It is just finding an appropriate way to split tasks without requiring a lot of bottlenecks in setting it up.
I might not mine coins, but I could see some benefit to having 35 TeraFLOPs across seven compute devices. I could also see Corsair wanting to sell me a power supply for said PC.

Tagged: Raspberry Pi
The Raspberry Pi is a tiny and cheap (as in a starting price of ~$28) computer that was originally intended for educational purposes. It is built around a Broadcom BCM2835 SoC which itself is based on the ARM architecture. Its VideoCore IV 3D graphics processor relies upon a closed-source driver because, until yesterday, Broadcom had not provided documentation or code. Technically, the code they released is for a different SoC but both Broadcomm and the Raspberry Pi Foundation believe the tools are there to port it over.
And the foundation wants to drum up interest by offering a $10,000 bounty for Quake III running acceptably on the Pi with the ported open source drivers.
If interested, you can look at Broadcom for the documentation and 3-clause BSD-licensed source code. You can also check out the Raspberry Pi Foundation for a blog post which mentions the competition (as well as their 2-year anniversary). GPU drivers are a good thing to be open-sourced. As I have been saying, the further "upstream" a piece of code is, the more it trickles down as a dependency for other software. The vocabulary that software needs to communicate with a hardware platform is quite high up there. Leaving those tools to society is a good thing for society.
Granted, it will probably not have a meaningful impact in this case... but there is a chance.

Amazon has been exploring changes to its Prime subscription service, and while drone air delivery may be years out, a music streaming service is a realistic possibility. The company already offers video streaming via its Prime service in the form of a limited selection of its total Instant Video library that can be streamed for free with a yearly Prime subscription. on the music side of things specifically, Amazon already has a massive downloadable paid-for MP3 library with a browser-based (and a new PC application) digital locker and media player.
Amazon Cloud Player, a browser-based media player for purchased MP3 files.
In short, all of the pieces for a music streaming service are in place. Amazon has the e-commerce and programing experience, distribution medium, and gobs of cloud storage and processing power. Amazon simply needs the go-ahead from the labels in the form of licensing agreements which appear to be in progress according to Recode.
An Amazon-run music streaming service would face stiff competition from existing competitors such as Spotify, but if any company can come in and make it work at scale in a competitive market it is Amazon. Especially if Amazon is able to replicate music streaming and offline caching using mobile apps like Spotify offers without charging extra for the privilege. Music streaming seems to be a natural addition to its Prime Instant offering, and may just be the spoonful of sugar that makes a possible Prime subscription price increase easier to swallow.

Tagged: microsoft, Windows Store, appstore
Microsoft introduced its own application download repository with Windows 8 along with an SDK for developers to put together touch friendly applications around the formerly-Metro-No-Longer-Modern-Whatever-It-Is-Called-This-Month user interface. Dubbed the Windows Store, it would be the source of applications for Windows RT, Windows Phone, and Windows x86/64 alike.
Since the release of Windows 8 Consumer Preview in February 2012, users have been able to use the Windows Store application to search for and download both free and paid-for apps. The Windows Store is a curated marketplace with applications that must be certified for compatibility by Microsoft who takes a percentage of sale price (30% or less depending on number of downloads).
At the end of last year, Microsoft had approximately 142,000 apps listed in the Store. Further, the company is seeing as many as 4 million application downloads per day from the Store. The 4 million downloads per day number was uncovered by Alex Wilhelm at TechCrunch, and is a 134.6% increase over the downloads/day number from October 2013. The breakdown of application type is pre-dominately free with paid applications acconting for less than half of the daily downloads (which makes sense).
At the current download rate, Microsoft could push as many as 1.46 billion app downloads a year. All things considered, the Windows Store is still dwarfed in downloads, number of apps, and popularity by the iOS, Google, and Mac app stores, but it is showing a surprising amount of growth lately. Hopefully this rise in popularity will beget more popularity from the cycle of developers getting interested in the Store and users getting new applications. (Ideally, as the Windows Store userbase grows, developers will have increased incentive to program new, or port existing, apps
to Metro which should further bring in new users and so on).
Have you used the Windows Store to find new Start Screen apps?

Tagged: steam, valve
Today, Valve announced that its Steam Family Sharing program is available for all users. This initiative allows Steam accounts to authorize devices to access their library on other accounts. The intention is for each family member to have their own account while being able to borrow games from one another. This can also extend to "their guests". It does not include titles which use third-party DRM, accounts, or subscriptions - Valve obviously does not have direct control over them.
There are other rules and restrictions, of course, but the account and device limits are quite high: 5 accounts across 10 devices. This does not get around region locks and a game which is VAC-banned cannot be shared. Ultimately, be careful sharing your games with your kids if they are jerks.
To setup Family Library Sharing in the Steam Client, go to View > Settings > Family and start to authorize and manage other computers. Just do not allow Cheating Charlie. For more information, check out Valve's promotional site and FAQ.

Tagged: linux, Chromebook
If you have purchased the Acer C720 Chromebook because it was relatively quick and very inexpensive you have probably been happy with it but maybe you wish it could do more. To do so you could follow these instructions to install either Ubuntu or Bohdi Linux. The process is a little more complicated than installing the OS from a CD but they have provided step by step instructions on how to accomplish this process. Bring new life to your Chromebook with just a bit of work.
"Chromebooks are amazing little machines. They are a marvel of speed and simplicity. The Acer C720 Chromebook is certainly near the top of the list of Chromebooks to be purchased (next to the Chromebook Pixel, of course). It's speedy and it's inexpensive. But for some, the simplistic nature of the devices doesn't offer enough power or flexibility. For those who need more from this Acer platform, I have the answer – in fact, I have two answers."
