Nvidia, Kepler, and Project Logan : Mobile Processors on the Rise

Nathan Simon Nathan Simon Profile: Nathan Simon

Now I am not a huge mobile gamer, I rarely play games that require any horsepower at all, but there are many people that do, and those people want better graphics. Well NVidia took a step in the right direction and have produced this. Check out the video below.

The Kepler GPU will bring PC class performance and power to mobile, including full support of traditional desktop-only features like OpenGL 4.4, Tessellation, and DirectX11. The addition of full CUDA 5.0 support for raw computational power makes the Kepler a real piece of future tech, and the first of the next generation’s mobile hardware. And it does it all using just two watts of power. Compare this to the current NVIDIA GeForce Titan desktop graphics card — which supports the same feature-set and needs 450 watts of power to do it. source androidcentral.com

So what do you think? All those features packed into a tiny processor, this could make for great gaming consoles, phones, and tablets. I could even see them using these in ultrabooks in the near future. No word on when we will see these in production, I will follow up when more information becomes available.

iPhone 6 Rumor : Larger Screens May be on the Horizon

Nathan Simon Nathan Simon Profile: Nathan Simon

Well if rumors are true, it’s about time Apple caters to people who crave a larger screen. Mind you Apple would be smart to keep the aspect ratio, but they will not, to properly increase the size of the iPhone 5,  they will have to increase the width more so than the length. Once again Apple sticks it to the developers!

It cited Apple’s suppliers in Asia, who said that Cupertino is testing a 12.9-inch iPad design and prototype iPhone screens larger than the current four inches. While Apple wouldn’t comment, of course, that jibes with an earlier Reuters report, which claimed it was considering 4.7- and 5.7-inch iPhone screens. Source engadget.com

I personally don’t know about a 5.7” iPhone, but a 4.7” iPhone would definitely be a welcome change to many people.

3,000MB/s Enterprise SSD Drive from Samsung

Nathan Simon Nathan Simon Profile: Nathan Simon

3GB/sec is fast, I mean, right now you might be running an OCZ drive that is capable of 685MB/sec, and for me that’s fast enough. I know there are some people out there that want to run this thing in their home computers, and kudos to you if you do so.

When they do arrive they will be released in in 400GB, 800GB and 1.6TB sizes. Over the next several years, Samsung expects to continue to develop a variety of NVMe SSD products with increasingly high performance levels.

Can you imagine how this will make database servers run, these drives could probably handle a couple thousand VDI machine boot storm as well… man I would love to try that out some day!

5-Inch Blackberry A10

Nathan Simon Nathan Simon Profile: Nathan Simon

blackberry a10

Okay I love Blackberry and all, but come on, you will not save yourself from demise if your next phone is a 5-Inch 720p dual-core phone… you need to do better then that, yeah a lot of people don’t care as much about specification and resolutions but if you want to really get back into the market, increase the specifications. How much would it hurt to put a 1080p screen in the phone? I guess they are working with what they have at the moment.

When I first heard about the Z10 and it was nearing release I also heard about the A10, it was supposed to be a quad-core beat of a phone, yet they are still going to use a dual-core processor… not going to work Blackberry.

Oh and where is my Black Berry Messenger, I am very impatient and would like to start BBMing friends!

VMware/Hyper-V and SAN Aligned Virtual Disks

Nathan Simon Nathan Simon Profile: Nathan Simon

If you are working with VMware of Hyper-V then you know what the heck I am talking about. Aligning the OS’ data blocks with the SAN.

There are many ways to do this, but a lot of people are unaware of easy ways to do so.

Some people know of the WMIC command, and some people know of Sysinternals DiskEXT. So how do you use these tools? Well let me show you.

WMIC

type this at the command prompt : wmic partition get BlockSize, StartingOffset, Name, Index

You will get the following output:

 BlockSize Index Name StartingOffset

512 0 Disk #1, Partition #0 1048576

512 0 Disk #2, Partition #0 1048576

512 0 Disk #0, Partition #0 1505755136

So what do those numbers mean to you? well as long as the StartingOffset (1048576 or 1505755136 in this example) are divisible by 4096 you are aligned with your storage.

Sysinternals is a little bit of the same, use this is WMIC gives you an error message.

As you can see, the disk are all aligned to the SAN.

If you are in a VMware specific environment and have miss-aligned VMs, the easiest way to re-align VMs is to V2V them. VMware Converter 5.x can create an optimized partition layout, if you are looking at cold cloning and hoping it will align blocks, it won’t. You need to warm clone the server. Believe in the software though, it works! Block level replication baby! :)

Xbox Beta Invite Open Now

Nathan Simon Nathan Simon Profile: Nathan Simon

Looking to get the latest from Microsoft and their Xbox? Look no further than your Xbox Dashboard, so turn that puppy on and get in on the Beta!

Sign up for the 2013 Xbox Live Update Xbox 360 Public Beta

We’re inviting Xbox Live members worldwide to participate in the 2013 Xbox Live Update for Xbox 360 Public Beta.* It will include updates to improve overall performance and the ability to conduct transactions with local currency, as Microsoft Points will be retired later this year.

Unlike our previous beta programs, sign up is now accessed directly through your Xbox 360 console to streamline the experience. Space is limited, so once the spots are filled the beta will be closed to the public.

To join, look for the Xbox Beta Program tile on the home hub of the Xbox Dashboard. source article

Some say it may have more integration with Windows 8, and also may look like the Xbox One console dashboard, I doubt it, but I won’t know because by the time I get on my Xbox they won’t have any spots left…

Also if you are looking for Xbox One information go here! Xbox One will be released November 30th, have you pre-ordered yours? I did! :)

New Android Exploit Leaves You Vulnerable.

Nathan Simon Nathan Simon Profile: Nathan Simon

A 4 year old security hole can make you android vulnerable to attack, that is of course if you install an app injected with this specific Malware.

The vulnerability apparently allows a hacker to turn a legitimate app into a malicious Trojan by modifying APK code without breaking the app’s cryptographic signature. Bluebox says the flaw exploits discrepancies in how Android apps are cryptographically verified and installed. Specifically it allows a hacker to change an app’s code, leaving its cryptographic signature unchanged — thereby tricking Android into believing the app itself is unchanged, and allowing the hacker to wreak their merry havoc. source techcrunch.com

Moral of the story is, don’t side load an application, make sure you download from the Google Play store and that the vendor is verified.

Logic Supply : Intel Rend Lake : New Fanless Systems on their way.

Nathan Simon Nathan Simon Profile: Nathan Simon

Intel Rend Lake Logic Supply Fanless Systems

Tom’s hardware did a little review on Logic Supply’s newest Intel NUC motherboard. I have used Logic Supply in the past and I have nothing but praise for them. The systems were rock solid from day one, customer support and vendor support is also excellent. Logic Supply excels in providing the best fanless systems for industrial or less than clean areas. No fans, no intake, no need to clean the inside of the system, awesome.

Check out an insert from the review below.

Logic Supply is officially the first to sell the D53427RKE ‘Rend Lake’ Intel NUC motherboard, the first Intel NUC motherboard to feature a Core i5 CPU.

If the upgrade to a Core i5 CPU wasn’t interesting enough, external connectivity has also been revised. The board now has one front USB 3.0 port, two rear USB 2.0 ports, another two USB 2.0 ports through an internal header, an HDMI 1.4a port, two Mini-DisplayPort 1.1a ports, and lastly, Gigabit Ethernet. The board also supports up to 16 GB of DDR3 SODIMM memory. Other internal connections include a PCIe-Mini slot (half-length), as well as a full-length mSATA slot.

Now go here to read the rest.
