AMD have just scooped up another Apple employee, who used to work for AMD. Raja Koduri will join the company as AMD's Corporate Vice President of Graphics Business, Visual Computing. Koduri's role at Apple was their Director of Graphics Architecture, something he has done for four years now. Koduri will be reporting to Mark Papermaster, who talked about Koduri joining the AMD ranks once again:

Maintaining AMD's position as a leader in visual computing is the key to our long-term success. As one of the industry's foremost experts in developing leading-edge visual computing solutions, Raja brings exceptional vision and strength to AMD's world-class engineering leadership team. Given his past record of success, Raja will help AMD lead the way in visual and accelerated computing and ensure we continue developing the industry-leading graphics IP that forms the foundation for our future growth.

This is the second person AMD have poached back from Apple, with the first being Jim Keller in August 2012. AMD reacquired Keller, making him their Corporate Vice President and Chief Microprocessor Architect. His position with Apple was as the Director of their Platform Architecture Group.

AMD's Radeon HD 8000 series is just around the corner, something I expect to be unveiled closer to Computex which happens in June, but for now, we have a tease of one of the GPUs in the HD 8000 series, the HD 8570.

The Radeon HD 8570 or "Oland Pro" is set to feature 384 stream processors (or GCN cores), 24 texture units and it should come with a clock speed of 720MHz. The memory side of things sees the HD 8570 with a 128-bit memory bus, where two versions will be available - the first, a 4.6GHz GDDR5 edition, and a 1.8GHz GDDR3 edition.

An Indian-based startup has created something quite incredible, the first true smartphone for the blind. The design had help from the Center for Innovation Incubation and Entrepreneurship and the Indian Institute of Management at Ahmedabad campus, and uses an invention that uses a screen that transforms into Braille characters as messages are received.

Sumit Dagar is behind the phone, and has said: "We have created the world's first Braille smartphone. This product is based on an innovative 'touch screen' which is capable of elevating and depressing the contents it receives to transform them into 'touchable' patterns".

Dagar has said that the response to the Braille smartphone has been immense so far, adding: "It comes out as a companion more than a phone to the user. We plan to do more advanced versions of the phone in the future".

Sometimes I feel like I have one of the more powerful Android-based devices when thinking of my Nexus 4, but sometimes, in the case of Facebook Home, I feel left out in the cold, and deserted.

Well, Facebook Home has been out for around a week now, and just how many downloads did it rack up in the last five days? Facebook Home has passed 500,000 downloads on the Google Play Store since its launch on April 16. Considering an app like Instagram saw one million downloads in a single day when it launched on Android, these Facebook Home numbers aren't so great.

I'm sure it'll continue to expand, but it looks like it might not be as quick as some may have previously thought.

Samsung's Galaxy Mega 6.3 is nearly here, but first it has to make its rounds at the FCC. When the Mega was announced, it was to feature LTE and HSPA+ radios, but the version below, has just HSPA+ support.

This is the model GT-i9200, the LTE-capable model is the i9205. This model most likely won't be pushed out of the United States, but it'll work well with AT&T's HSPA+ bands.

Google I/O is less than a month away, and we should expect some amazing things to come from the conference. SidhTech are reporting from unnamed sources that we should see if a new Nexus 4 with LTE.

A new Nexus 4 with LTE means no Nexus 5 or X Phone, which is really disappointing. SidhTech are reporting that Google will unveil a new 32GB Nexus 4 with LTE and CDMA compatibility. Two of the biggest complaints among Nexus 4 users was the storage (or lack of upgradeable storage) and no LTE capabilities.

I think for Google to continue pushing a few steps ahead of Apple, they need to release this teased and upgraded Nexus 4, but blow everyone away with a high-end device. Unveil the Nexus 5 or X Phone, come on Google, do it.

If you have a spare $15 million and don't mind spending it on a single device, then whip out your credit card and prepare for a mountain of frequent flier miles. Stuart Hughes, a Liverpool, England-based company have crafted an iPhone 5 worth $15 million.

Stuart Hughes used 600 flawless white diamonds with the specifically-adapted, solid gold housing, with the Apple logo on the back getting some beautiful treatment - with 53 diamonds to itself. The home button is made from a rare 26-carat black diamond, which on its own is worth an absolutely mind- and wallet-busting $14.5 million.

Even if I were a billionaire, I don't think I could ever spend $15 million on what is, at the end of the day, just an iPhone.

HTC's One smartphone definitely looks like a winner, but there are always things that can push a prospective buyer over the edge, to the point of pulling their wallet out and buying it.

A simple Google+ post from Koushik Dutta, who works with ClockworkMod, used the HTCDev unlock on his One smartphone, where he says some magic words about it: "Uh. So, I wasn't expecting this, but the HTCDev unlock on this device actually behaves properly, unlike its predecessors. It behaves like a Nexus device".

So there you have it, an unlocked HTC One is pretty much a Nexus device. This is something I've asked about for a very long time - why don't smartphone makers give us the ability to roll back to stock Android? It looks like HTC's One might just be that little bit better than the competition in that regard.

Some lucky AT&T customers are set to receive their Samsung Galaxy S4 smartphones earlier than anticipated, with reports coming out that some customers who have ordered the Galaxy S4 have noticed that their smartphone will ship on April 23, and not April 30.

Engadget have captured a screenshot from AT&T's website showing that there is indeed an April 23 shipping date for some customers. T-Mobile should begin offering their Galaxy S4's online on April 24, and they will have physical phones in their stores on May 1.

Windows 8.1 has seen its third leak, arriving to file sharing websites as build 9374. Build 9374 of Windows 8.1 doesn't seem to include any huge changes, but there is one interesting new addition: Kiosk Mode.

Kiosk Mode can be found in the PC settings menu, and seems to be a way of locking down a device to a single Windows 8-style application. These apps can be selected to launch at login, with the app lockdown in place for user accounts. Kiosk Mode seems destined for business users, or someone who wants to set it up in an embedded-like terminal that runs a single application.

Retail units could be deployed to run a single application, or business devices that allow employees to run a line-of-business application.

There are more people gaming on Mac's thanks to the popularity of Apple's MacBook Pro's and their iMac's, with most thanks given to Intel who made their way into Apple machines across the world.

Logitech have just stepped up, announcing that their Logitech Gaming Software is now compatible with Mac OS for all of their keyboard and mouse products. This means that Mac-based gamers can now enjoy the same personalization and customization of their products that PC gamers have enjoyed for years now. You can download the latest version of the Logitech Gaming Software from the Logitech support page.

HTC's One smartphone might not have captured as many users as they'd like, but that hasn't stopped the company from preparing another smartphone. DigiTimes is reporting that the currently codenamed M4 smartphone would be released in mid-June, featuring a "metal-alloy chassis".

The chassis is being supplied by Catcher Technology, with the rest of the smartphone reportedly consisting of a 4.3-inch 720p HD display, a 1.2GHz Snapdragon 400 processor, and an "Ultrapixel" rear-facing camera. We should also see 16GB of internal flash storage, 1GB of RAM and Android 4.2.2 Jelly Bean with HTC's Sense 5 UI sprinkled on top. We should expect the M4 to drop in June, with widespread availability in Q3 2013.

The Xbox 360 has enjoyed its position as the best-selling console in the United States for the 27th consecutive month in a row according to new data from NPD Group. Last month, there were 261,000 Xbox 360 units sold in the US, beating both the PS3 and Wii U.

Physical sales were down 10% year-over-year, with $992.5 million in March 2013 compared to $1.1 billion in the same month of 2012. Software sales didn't rise, but they didn't fall much either, dropping just 1% year-over-year. The biggest decline came from hardware sales, dropping 32% to $221.6 million. This should be solved with the upcoming next-generation consoles. Portable consoles are having problems, experiencing a "stronger decline" than traditional ones.

Up until now, we control our tablets with our hands, but if Samsung has anything to do with that, it could all change. Samsung's Emerging Technology Lab has teamed up with the University of Texas' electrical engineering professor, Roozbeh Jafari, to research "how to bring mind control to its mobile devices with the hope of developing ways for people with mobility impairments to connect to the world".

A brain-controlled tablet isn't anywhere near ready, nor are they at the point of a marketable prototype yet, but Technology Review has reported that their current plans for a mind-controlled tablet involve "a cap studded with EEG-monitoring electrodes" that monitors "well-known brain activity patterns that occur when people are shown repetitive visual patterns".

Technology Review were treated to a demonstration of the technology, where researchers were able to open apps on their tablets by just concentrating on icons that were "blinking at a distinctive frequency".

CISPA was passed in the House yesterday, not receiving much mainstream attention because the public eye is glued to the events in Boston and Texas, but Anonymous have your back. The hacking collective are wanting a protest against the Cyber Intelligence Sharing and Protection Act (CISPA) on April 22.

The protest they want to see is an "Internet Blackout Day" where they want "web developers and website owners to go dark" and to also "display a message as to why you are going dark, and encourage others to do the same".

If you're sitting in Canada right now wishing you could purchase the Samsung Galaxy Note 8.0, well, now you can. The 8-inch tablet is available at Best Buy, Future Shop, Staples and other authorized retailers for $429.

If you don't know the skinny on the Note 8.0 by now, you'll be greeted with a 1280x800 8-inch display, Samsung's own Exynos 4412 quad-core processor, 16GB of internal storage, 2GB of RAM and rear- and front-facing cameras. Android 4.1 Jelly Bean makes an appearance, with Samsung splashing TouchWiz on top, with all sorts of stylus-optimized applications.

Ouya have provided another shipping update to their upcoming Android-based console, taking to their Kickstarter page and through e-mail, notifying consumers of some new information. Limited Edition units have been "fast-tracked", and will be finally shipping out sooner, nearly two weeks earlier than they were estimated to.

Standard orders are no longer prioritized over orders with extra controllers, with the orders including spare controllers to start shipping next week. The company are also working on methods of getting international orders out to backers faster, too. I'm looking forward to receiving my Limited Edition Ouya console, with some user names etched into the controllers, booyah.

Yahoo has decided to take some advice from rival Google and cut the ambilical cord to some services that have been underperforming. This morning the once king of search announced that it would be shutting down several features that have not performed well as of late.

Yahoo Deals, Yahoo Upcoming, Yahoo Kids, Yahoo SMS Alerts, and the feature phone versions of Yahoo Mail all will see their lives come to an end April 30th. Older versions of Yahoo Web Mail will also see a shut down during the week of June 3rd. The shutdowns come as Yahoo CEO Marissa Meyer restructures the company and refocuses their goals into something profitable.

Last month Twitter announced that it would be shutting down TweetDeck Air, TweetDeck for Android, and TweetDeck for iOS but had not finalized the date on which the apps would go offline. Today we found out that date.

May 7th will be the last time that the TweetDeck mobile apps will see the light of day. They will be removed from their app stores and their APIs turned off. Facebook integration to TweetDeck will also cease to function.

Twitter says that both the Windows and Mac versions will stick around for the time being and will slowly be updated following browser updates. No word on if we will see a TweetDeck like replacement for mobile devices anytime soon though and our advice would be not to hold your breath.

This year marks the 23rd anniversary of the Hubble Telescope taking flight in orbit around the earth. To celebrate the occasion it revisited one of my favorite monuments in the night sky; the Horse Head Nebula (IC 434).

Located within the Orion Nebula (M42), the Horsehead is a massive star forming region which is comprised of dust and gas. The Hubble first imaged the Horse Head about 20 years ago and the resulting visible light image can be seen above. The red or pinkish glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis. The darkness of the Horsehead is caused mostly by thick dust, although the lower part of the Horsehead's neck casts a shadow to the left.

The new image of the great Horse Head can be seen above. It shows the region in infrared light, which is made up of longer wavelengths than visible light and can see through the dusty cloud that usually obscures the nebula's inner regions. The result is a rather amazing, and stunning looking structure, made of delicate folds of gas.
