  • Speaking at AMD Fusion conference

    - by Daniel Moth
    Next Wednesday at 2pm I will be presenting a session at the AMD Fusion developer summit in Bellevue, Washington State. For more on this conference please visit the official website. If you filter the catalog by 'Speaker Last Name' to "Moth", you'll find my talk. For your convenience, below is the title and abstract Blazing-fast code using GPUs and more, with Microsoft Visual C++ To get full performance out of mainstream hardware, high-performance code needs to harness, not only multi-core CPUs, but also GPUs (whether discrete cards or integrated in the processor) and other compute accelerators to achieve orders-of-magnitude speed-up for data parallel algorithms. How can you as a C++ developer fully utilize all that heterogeneous hardware from your Visual Studio environment? How can your code benefit from this tremendous performance boost without sacrificing your developer productivity or the portability of your solution? The answers will be presented in this session that introduces a new technology from Microsoft. Hope to see many of you there! Comments about this post welcome at the original blog.

  • unable to mount internal disk mount exited with exit code 13

    - by Masri
    My Ubuntu get into error when I try to mount one of my internal disks and it gives this error message: Error mounting: mount exited with exit code 13: $MFTMirr does not match $MFT (record 3). Failed to mount '/dev/sda7': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. pls advise how to solve above error ,Many thanks to you in advance.

  • Proper way to measure the scalability of web Application

    - by Jorge
    Let's say that I have a web Application where i'm going to have 300 users and each one have to see data on real time, imagine that each client make an ajax call to the server to see in real time what's happens with the changes of the data, this calls are made each 300 ms per user. I know that i can run a simulation to see if the hardware of my server supports this example. But what happen's if the number of users start to grow up. Is there a way that i can measure the hardware needed to handle this growing behavior, a software, a formula, algorithm or maybe recommend me if i need to implement an distributed application with multiplies servers and balance the loads.

  • Sound plays from laptop speakers only even when headphones are connected

    - by Ankush N Nayak
    I'm using a Dell Vostro 1014 laptop with Ubuntu 11.10. From the time I had Ubuntu 9.04, sound comes from the laptop speakers only even when I plug in earphones or external speakers. Also, if an external microphone plugged in, it does not work. Dell even replaced my motherboard to check for hardware issues but the problem persists. So it is definitely not a hardware issue. The sound plays perfectly through the headphones in the pre-boot diagnostics. So I figure, this must be a problem with Ubuntu not recognizing my sound card. Please try to give a solution for this problem.

  • Broadcom BCM4313 working, but terribly slow

    - by Ataraxio Panzetta
    Hi all, I've installed ubuntu on a Asus 1015 netbook. Everything worked out of the box except for the Wireless adapter, which i had to install with the Additional Drivers application. It apparently installed fine and connects to our wireless network, but it only works at a "funny" speed range that goes from 367Bytes to a peak of 3Kb in its best moments. I know for sure the problem is neither the network nor the hardware. Network speeds are normal under windows on this laptop and in other computers with ubuntu aswell. lspci says the card is a BCM4313 model, but the Addittional Drivers Manager says these packecege contains Broadcom 802.11 Linux STA wireless driverfor use with Broadcom's BCM4311-, BCM4312-, BCM4321-, and BCM4322 based hardware seems like it installed the wrong driver... Is there anything I can do? I'm not concerned about compiling the driver or stuff like that, but I'm not sure on where to start... any help or guidance will be very, very appreciated.

    Hi, My Ubuntu 10.10 just crashed(probably due to hardware error and in the end I was getting error like Unknown filesystem ..... grub> .. GRUB console before i could take some action) and i reinstalled the same version form USB stick. I had ubuntu installed in ext4 file system and I am also having the same filesystem in the same hard disk on different drive. When I try to access my previous filesystem, i get error Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so I had some important files in the previous volume, I don't know how to retrieve them. And what are the chances that I would get the same outcome (hardware error)? Please help me!

    ORCLville: OOW 2012 - Crystal BallOracle ACE Director Floyd Teter cooks up some tongue-in-cheek predictions for news and announcements that might come out of Oracle OpenWorld 2012. What's your prediction? Oracle Optimized Solutions at Oracle OpenWorld 2012 | Oracle Hardware Hardware matters, too! The people behind the Oracle Hardware blog have put together a list of Oracle Openworld 2012 sessions focused Oracle Optimized Solutions, "designed, pre-tested, tuned and fully documented architectures for optimal performance and availability." Just plug the session ID numbers into Schedule Builder and you're good to go. AIX Checklist for stable OBIEE deployment | Dick Dunbar "OBIEE is a complicated system with many moving parts and connection points," according to Oracle Business Inteligence escalation engineer Dick Dunbar. "The purpose of this article is to provide a checklist to discuss OBIEE deployment with your systems administrators." Demo for OPN: Coherence Management with EM Cloud Control 12c Oracle Partner Network members can check out a new Coherence Management demo that showcases some of the key capabilities of Management Pack for Oracle Coherence and JVM Diagnostics. "The demo flow showcases the key enhancements made in Enterprise Manager 12c release which includes new customizable performance summary, cache data management and configuration management," according to the WebLogic Partner Community EMEA blog. The Pragmatic Architect: To Boldly Go Where No One Has Gone Before | Frank Buschmann "Many architects have technical knowledge that's both impressive and sound, which is indeed an inevitable basis for design success," says Frank Buschmann. "Yet, a lot of software projects fail or suffer due to severe challenges in their architecture. The key to mastery is how architects approach design, what they value, and where they focus their attention and work." As retail dies, whom will be the winners? | Peter Evans-Greenwood "The problem for many retailers is that how consumers shop has changed but the the retailers haven't adapted, " says Peter Evans-Greenwood. "Their sole virtue was to be the last step in a supply chain delivering somebody else's products to the consumer. However, being the last step in the supply chain is no longer a virtue when consumers skip across channels and can reach around the globe, no longer dependant on or limited to what they can find locally." Thought for the Day "Brains require stimulation. If you're locked into a pattern of work, work, and more work, your brain soon habituates - the same way that it lets you stop hearing a clock ticking. So, if you want to be more effective at work, you must, paradoxically, be less single-minded in your devotion to work. Anything you do—anything—that stimulates new segments of your brain will make you a more effective programmer or analyst. I promise, with a money-back guarantee." — Gerald M.

  • 0.00006103515625 GB of RAM. Is .NET MicroFramework part of Windows CE?

    - by Rocket Surgeon
    The .NET MicroFramework claims to work on 64K RAM and has list of compatible targets vendors. At the same time, same vendors who ship hardware and create Board Support Packages (vendors like Adeneo) keep releasing something named Windows 7 CE BSP for the same hardware targets. Obviously the OS as heavy as WinCE needs more than 64K RAM. So, somehow .NET MicroFramework is relevant to WinCE, but how ? Is it part of bigger OS or is it base of it, or are both mutually exclusive ? Background: 0.00006103515625 GByte of RAM is same as 64Kbyte of RAM. I am looking for possiblity to use Microsoft development tools for small target like BeagleBone. http://www.adeneo-embedded.com/About-Us/News/Release-of-TI-BeagleBone Nice. Now .. where is a MicroFramework for the same beaglebone ? Is it inside the released pile ?

  • Running C++ AMP kernels on the CPU

    - by Daniel Moth
    One of the FAQs we receive is whether C++ AMP can be used to target the CPU. For targeting multi-core we have a technology we released with VS2010 called PPL, which has had enhancements for VS 11 – that is what you should be using! FYI, it also has a Linux implementation via Intel's TBB which conforms to the same interface. When you choose to use C++ AMP, you choose to take advantage of massively parallel hardware, through accelerators like the GPU. Having said that, you can always use the accelerator class to check if you are running on a system where the is no hardware with a DirectX 11 driver, and decide what alternative code path you wish to follow.  In fact, if you do nothing in code, if the runtime does not find DX11 hardware to run your code on, it will choose the WARP accelerator which will run your code on the CPU, taking advantage of multi-core and SSE2 (depending on the CPU capabilities WARP also uses SSE3 and SSE 4.1 – it does not currently use AVX and on such systems you hopefully have a DX 11 GPU anyway). A few things to know about WARP It is our fallback CPU solution, not intended as a primary target of C++ AMP. WARP stands for Windows Advanced Rasterization Platform and you can read old info on this MSDN page on WARP. What is new in Windows 8 Developer Preview is that WARP now supports DirectCompute, which is what C++ AMP builds on. It is not currently clear if we will have a CPU fallback solution for non-Windows 8 platforms when we ship. When you create a WARP accelerator, its is_emulated property returns true. WARP does not currently support double precision.   BTW, when we refer to WARP, we refer to this accelerator described above. If we use lower case "warp", that refers to a bunch of threads that run concurrently in lock step and share the same instruction. In the VS 11 Developer Preview, the size of warp in our Ref emulator is 4 – Ref is another emulator that runs on the CPU, but it is extremely slow not intended for production, just for debugging. Comments about this post by Daniel Moth welcome at the original blog.

  • Will Apple abandon OpenCL?

    - by John
    I am developing OpenCL applications, amongst others for MacOS. The new Macbook pro 13 inch comes with an Intel HD Graphics 3000 card so it seams reasonable to assume all their mainstream computers like Macbook and Mac mini will also come out with this Intel graphics card soon. OpenCL is not available for Intel graphics cards. Intel having a terrible reputation in developing graphics drivers and Apple knowing this makes me wonder Apple is abandoning OpenCL already again. Especially considering OpenCL should run anywhere, not only on high end systems. Developing applications only for the high end Macs with dedicated graphics hardware or for previous generation hardware with the Geforce 320M would not be a feasible option for me. Does anybody have any thoughts on this?

  • 50 Billion Served: Java Embedded on Devices

    - by Tori Wieldt
    It doesn't matter if it is 50 billion or 24 billion, just suffice it to stay that there will be MANY connected devices in the year 2020. With just 24 billion devices, they will outnumber humans six to one! So as a developer, you don't want to ignore this opportunity. What if you could use your Java skills and deploy an app to a fraction of these devices (don't be greedy, how about just, say, 118,000 of them)? Fareed Suliman, Java ME Product Manager had lots of good news for Java Developers in his presentation Modernizing the Explosion of Advanced Microcontrollers with Embedded Java at ARM TechCon in Santa Clara, CA last week. "A radical architecture shift is underway in this space, from proprietary to standards-based," he explained.  He pointed out several advantages to using Embedded Java for devices: Java is a proven and open standard. Java provides connectivity, encryption, location, and web services APIs. You don't have to focus on and keep reinventing the plumbing below the JVM. Abstracting the software from the hardware allows you to repeat your app across many devices. Abstracting the software from the hardware allows allows parallel development so you can get your app done more quickly. You already know Java (or you can hire lots of Java talent). Java is a full ecosystem, with Java Embedded plugins for IDEs like Eclipse and NetBeans. Java ME allows for in-field software upgrades. Suliman mentioned two ways developers can start using Java Embedded today:  Java ME Embedded Suite 7.0 Oracle Java Embedded Suite is a new packaged solution from Oracle (including Java DB, GlassFish for Embedded Suite, Jersey Web Services Framework, and Oracle Java SE Embedded 7 platform), created to provide value added services for collecting, managing, and transmitting data to embedded devices such as gateways and concentrators. Oracle Java ME Embedded 3.2 Oracle Java ME Embedded 3.2 is designed and optimized to meet the unique requirements of small embedded, low power devices such as micro-controllers and other resource-constrained hardware without screens or user interfaces. Think tiny. Really tiny. And think big.  Read more about Java Embedded at the Oracle Technology Network, and read The Java Source blog Java Embedded Releases from September.

  • Uniquely identify a mobile device

    - by Sahil Malik
    SharePoint, WCF and Azure Trainings: more information Sometimes you need to identify every device your app is installed on uniquely. This is for instance important where you have per-device licensing restrictions. For Win8 store apps, You can use ASHWID (Application Specific Hardware Identifier). ASHWID will be different app to app and device to device. Any hardware changes to the device will cause the unique id to change. You can also detect minor change vs. major change to build custom level of tolerance in what is considered a change. For instance, ejecting a USB stick is a minor change. The below code snippet shows you how to get the unique device id, Read full article ....

  • How to make Pokémon White 3D effect?

    - by Pipo
    I just wondered how to create a 3D effect similar to Pokemon White/Black? It seems to be not polygon based, but created just with sprites. If the perspective changes the sprites stay sharp and don't get blurred. How can I archive this? Source: https://www.youtube.com/watch?v=fZEPUPYOnRc&feature=youtube_gdata_player Edit: Wow, two downvotes because I used a video instead of screenshots? Don't get me wrong, I thank you, because you want to help me, but the 3D effect can be better understand in motion. Anyway, here is a screenshot: http://wearearcade.com/wp-content/uploads/2011/03/pokemon-black-white-starter-town.jpg So, if this is a hardware limitation, how can I archive this o na different hardware, e.g. a HTML5 game?

  • What is the situation about OpenGL under Ubuntu Unity and Gnome3?

    - by user827992
    In a GNU/linux distribution is usually installed Xorg as main graphical server, it operates with a client-server logic, a special windows is designate as desktop environment and this special windows can handle all the eyecandy stuff like decorations, icons and effects. The problem is that the latest UI heavily relies on hardware acceleration, Unity is an overlay on Compiz and the Gnome-shell also require an active driver for the GPU to work well: the problem is: on the same OS I can find multiple implementations of OpenGL who is handling my OpenGL buffer? how the OpenGL buffer is managed compared to the other windows? how can I be sure that my OpenGL implementation is glued to the hardware and is not related to the client-server logic of Xorg? For example I have tried the clutter library and I have only experienced problems under both Unity and GTK/Gnome, no problem under other OS.
