  • What are the minimum hardware requirements for the latest version of Android Jelly Bean OS?

    - by Stom
    I searched around, and there's no information that points exactly to the suggested, minimum, or otherwise dated information containing specifications on this. I want to install a newer version of Android on an older ZTE-X500 MetroPCS smartphone. However, I'd like to know the backwards compatibility in regards to using a newer featured OS with lackluster, limited hardware compared to today's smartphones, such as Galaxy S4. However, I still wish to do this. If Jelly Bean is too demanding, I will set up Honeycomb, or get a modified Honey Comb ROM, or tweak the source to my preferences. However, nothing outlines the specifics of the "system requirements" it suggests for optimum performance, such as RAM, processor speed, processor features, and/or any other features, like DMA, video circuit advancements, and/or sound and special hardware requirements noted as well. Please, if you will, point me to a source that mentions this, and please tell do not link me to any PDF file formats. Thank you. PS: I'm a computer programmer.

  • Why is windows 7 marking all my extra RAM as "hardware reserved"?

    - by pinkmuppet
    I have a new HP Z800 Workstation, running Windows 7 Enterprise 64 bit. The machine has 4GB of RAM -- windows reported 1.99GB available, 2GB was "hardware reserved". I added another 2 GB and windows reports that there is 6GB of physical RAM, but now 4GB is "hardware reserved". The BIOS sees the full RAM amount as well. The video card is an nVida Quadro FX 580, so it shouldn't be using any shared memory at all. whats going on? Z800 Specs are here.

  • Is there such thing as hardware encrypted raid disk?

    - by Dumitrescu Bogdan
    I have a server for which I want to protect the content. The server is located on a clients premises. Is there a way to encrypt the content of a RAID DISK (at hardware level) ? What I need is that the server will not be able to start as long as the required password is not provided (the encryption key) I will give the best answer to Miles, though the answer was not exactly to my question. But from all the comments, it seems that it cannot be done hardware or .. it cannot be done as I would like to.

  • Is there a test to see if hardware virtualization (vmx / svm) are presently enabled within a Linux session?

    - by Dr. Edward Morbius
    I'm writing procedures for configuring VirtualBox support for 64-bit SMP guests, which requires hardware virtualization suppot (VTx/Intel, AMD-V/AMD). I have successfully configured this myself, however I'd like the procedure to be clear. sed -ne '/^flags/s/^.*: //p' /proc/cpuinfo | egrep -q '(vmx|svm)' && echo Has hardware virt || echo No HW virt ... shows if the CPU is capable. I've still got to go enable the feature in BIOS. Any way to test from within Linux to see that this is no or not? Thanks. (Edit: s/xvm/svm/ in title)

  • Can a power failure or forceful shutdown damage hardware?

    - by Vilx-
    Can computer hardware suffer damage from forceful shutdowns (holding the power button for five (5) seconds) or power failures? I believe that normal PC hardware does not suffer from this - after all, it's not much different than what they experience under a standard shutdown. But elsewhere I've read tht another person thought that it could do physical harm to the hard drive and possibly other components as well. He also said that the journaling features of filesystems are useless in face of power failures and were intended to help mitigate damage from system crashes. I think this is nonsense, but then again I lack the experience and knowledge to say it with certainty.

  • Is there any Mac Pro hardware parts that can ONLY be purchased thru Apple?

    - by bigp
    I'd like to know if I need to be concerned about any hardware parts that I should include in a brand new Mac Pro purchase, instead of trying to hunt it down on 3rd party vendors (or whitelist vendors / hardware suppliers). The main components I'm interested for "upgradeability" are: Processors (If starting with Two 2.4GHz Quad-Core "Westmere"); RAM (If starting with the least possible, which seems to be 6 x 1GB); Video Cards (If starting with one ATI Radeon HD 5770, can a 2nd one be purchased elsewhere?) Hard-Drives (Since these are mounted in specialized trays [if I'm not mistaking], are they also sold elsewhere? And can they be bought as SSDs?) Power Supply (Do I need to be concerned about this at all, or does it auto-adjust depending on the new component upgrades?) I just want to be sure by choosing a Mac Pro with lower component specifications that I can in fact purchase upgrade parts cheaper elsewhere. Thanks!

  • Why are my hardware tabs disabled for my VMWare player image?

    - by djangofan
    I just installed a Ubuntu 10.10 image on VMWare player and after I finished installing I was messing with the hardware settings and I did the following: 1. disabled the floppy device 2. changed the CDRom to "use system cdrom" 3. tried to enable the VMWare tools but it complained that the vm was in "Easy Install" mode After I fiddled with the VM now my floppy and 2 CD rom devices as well as sound card and USB settings are all disabled in the VM hardware settings. Any idea on why this occurred and how to fix it?

  • Is an I/O benchmark made for hardware an accurate assessment of a Windows VM's performance under vSphere 5?

    - by Jeremy
    We support an enterprise application running on Windows Server 2008 R2. One of our customers has chosen to install to VMWare, and what I'm finding is that the VM's are relatively slow compared to hardware. Our product development team has advised that many VMs appear to run particularly slow on I/O benchmarks, which impact performance in production. I've tried the AttoSoft I/O benchmark and find that for smaller I/O blocks (1-32K) the VM I'm looking at is 25x slower than hardware and for larger I/O blocks (1-8MB) it's 10x slower. Is this a fair benchmark? If not, any suggestions for a fair test?

  • Hosing website on own server. What is Hardware requirement and Cost [closed]

    - by KuKu
    As i am about to finish my dream website, i need to host it on some server. I checked Amazon AWS Free Tier, i found it pretty complex. As i made full website in java(JSP + Servlet + mysql + Node.js), its been expensive to host. So i thought that why not to host on own server so that i will be fully dependent on my resources, not on any one else. And i know, in future i need to pay more and more to the other hosting company(because of uploading images and number of incoming users). So my question is, On initial stage what kind of hardware i will required. What can be the cost of that hardware? I already have 12MBPS broadband connection, will it be sufficient? It has static IP Address as well.

  • Win32: Is there a replacement GDI32.dll that uses hardware acceleration?

    - by Ian Boyd
    Has anyone out there created a version of GDI32.dll that takes advantage of hardware acceleration available on the machine? gdiplus.dll? Starting with Windows Vista, GDI is no longer hardware accelerated. (GDI+ was never hardware accelerated). Without Microsoft fixing GDI (and GDI+) to be able to run well on the computer: native applications (C++ MFC, Delphi, etc), and managed WinForms applications, will continue to run poorly forever. While i could use Direct2D for business applications, i cannot control the fact that the development environment still creates controls, with decades of library support code, that assumes the presence of GDI.

  • How do I get details about how Network and Sharing Center detected a problem?

    - by Matthew Scouten
    When I open Network and Sharing Center in Windows 7, it puts a red X between the network and the internet, but when I run Troubleshoot Problems it tells me that it does not know what the problem is. Is there any way to tell what test Windows used to place that red X, and how it failed? The system obviously knows something that it is not telling me. Knowing the details would help me solve this problem.

  • Sharing a texture resource from DX11 to DX9 to WPF, need to wait for DeviceContext.Flush() to finish

    - by Rei Miyasaka
    I'm following these instructions on TheCodeProject for rendering from DirectX to WPF using D3DImage. The trouble is that now that I have no swap chain to call Present() on -- which according to the article shouldn't be a problem, but it definitely wasn't copying my back buffer. An additional step that I have to take before I can copy the texture to WPF is to share it with a second D3D9Ex device, since D3DImage only works with DX9 (which is understandable, as WPF is built on DX9). To that end, I've modified some SlimDX code to work with DirectX 11. I tried calling DeviceContext.Flush() (the Immediate one) at the end of each render cycle, which kind of works -- most of the time it'll show my renderings, but maybe for maybe 3 or 4 out of 60 frames each second, it'll draw my clear color instead. This makes sense -- Flush() is non-blocking; it doesn't wait for the GPU to do its thing the way SwapChain.Present does. Any idea what the proper solution is? I have a feeling it has something to do with my texture parameters for the back buffer, but I don't know.

  • Sony Vaio PCG-71315L "Wireless is disabled by hardware switch" Help!

    - by Luke Rossi
    I'm a new user to Ubuntu and Linux as a whole, I've had it for a few months and just as I'm starting to get a feel for things my wireless decided to quit on me. This puzzled me so i checked all the switches on the Vaio; my wireless switch was on (my bluetooth was also working), and in my windows partition the problem is non-existent. Help please? Anyways after executing the "rfkill list" command this was the outcome: 1: sony-wifi: Wireless LAN Soft blocked: yes Hard blocked: no 2: sony-bluetooth: Bluetooth Soft blocked: no Hard blocked: no 3: phy0: Wireless LAN Soft blocked: yes Hard blocked: yes 4: hci0: Bluetooth Soft blocked: no Hard blocked: no As stated in the title my laptop is a Sony Vaio PCG-71315L

  • Can't use the hardware scissor any more, should I use the stencil buffer or manually clip sprites?

    - by Alex Ames
    I wrote a simple UI system for my game. There is a clip flag on my widgets that you can use to tell a widget to clip any children that try to draw outside their parent's box (for scrollboxes for example). The clip flag uses glScissor, which is fed an axis aligned rectangle. I just added arbitrary rotation and transformations to my widgets, so I can rotate or scale them however I want. Unfortunately, this breaks the scissor that I was using as now my clip rectangle might not be axis aligned. There are two ways I can think of to fix this: either by using the stencil buffer to define the drawable area, or by having a wrapper function around my sprite drawing function that will adjust the vertices and texture coords of the sprites being drawn based on the clipper on the top of a clipper stack. Of course, there may also be other options I can't think of (something fancy with shaders possibly?). I'm not sure which way to go at the moment. Changing the implementation of my scissor functions to use the stencil buffer probably requires the smallest change, but I'm not sure how much overhead that has compared to the coordinate adjusting or if the performance difference is even worth considering.

  • What is the *correct* term for a program that makes use of multiple hardware processor cores?

    - by Ryan Thompson
    I want to say that my program is capable of splitting some work across multiple CPU cores on a single system. What is the simple term for this? It's not multi-threaded, because that doesn't automatically imply that the threads run in parallel. It's not multi-process, because multiprocessing seems to be a property of a computer system, not a program. "capable of parallel operation" seems too wordy, and with all the confusion of terminology, I'm not even sure if it's accurate. So is there a simple term for this?

  • What is a technique for 2D ray-box intersection that is suitable for old console hardware?

    - by DJCouchyCouch
    I'm working on a Sega Genesis homebrew game (it has a 7mhz 68000 CPU). I'm looking for a way to find the intersection between a particle sprite and a background tile. Particles are represented as a point with a movement vector. Background tiles are 8 x 8 pixels, with an (X,Y) position that is always located at a multiple of 8. So, really, I need to find the intersection point for a ray-box collision; I need to find out where along the edge of the tile the ray/particle hits. I have these two hard constraints: I'm working with pixel locations (integers). Floating point is too expensive. It doesn't have to be super exact, just close enough. Multiplications, divisions, dot products, et cetera, are incredibly expensive and are to be avoided. So I'm looking for an efficient algorithm that would fit those constraints. Any ideas? I'm writing it in C, so that would work, but assembly should be good as well.

  • Why isn't Japanese software industry as strong as their hardware technology?

    - by Joan Venge
    I admire Japanese technology and their innovation. They always seem to be one step ahead of everyone else. But why isn't their software industry just as developed? Why aren't there any Japanese operating systems, high-end game engines, 3D digital content creation applications? I would like to see their take on these and I think it could bring alot of innovation. Btw I mentioned 3D software because the animation industry is strong there as well, but they are using North American software for this.

  • Sharing business logic between server-side and client-side of web application?

    - by thoughtpunch
    Quick question concerning shared code/logic in back and front ends of a web application. I have a web application (Rails + heavy JS) that parses metadata from HTML pages fetched via a user supplied URL (think Pinterest or Instapaper). Currently this processing takes place exclusively on the client-side. The code that fetches the URL and parses the DOM is in a fairly large set of JS scripts in our Rails app. Occasionally want to do this processing on the server-side of the app. For example, what if a user supplied a URL but they have JS disabled or have a non-standard compliant browser, etc. Ideally I'd like to be able to process these URLS in Ruby on the back-end (in asynchronous background jobs perhaps) using the same logic that our JS parsers use WITHOUT porting the JS to Ruby. I've looked at systems that allow you to execute JS scripts in the backend like execjs as well as Ruby-to-Javascript compilers like OpalRB that would hopefully allow "write-once, execute many", but I'm not sure that either is the right decision. Whats the best way to avoid business logic duplication for apps that need to do both client-side and server-side processing of similar data?

  • What the different hardware temperatures listed in psensor, sensor viewer etc reffer to?

    - by cipricus
    I have installed psensor and see a list of temperatures, but listed as ”Temperature 1”, 2, 3 etc . I can only guess where the processor is: but who's who for sure? The same question stands for Sensors Viewer. I can also type sensors in Terminal but I get no more than that acpi -t gives Thermal 0: ok, 65.0 degrees C Thermal 1: ok, 37.9 degrees C Thermal 2: ok, 56.0 degrees C Thermal 3: active, 71.0 degrees C Considering psensor, I know for a fact that: - the temperature that varies most depending on the CPU use is Temp1 and it is one of the two highest - the other high temperature is Temp4 and it goes to the ceiling when using youtube/flash - Temp2 is very stable at a medium level of 50-60 degrees Celsius - Temp3 is by far the lowest and most imobile So, I guess Temp1 is the CPU temperature, and Temp4 is the GPU temperature. Temp2 and 3 must be the motherboard and the hdd. Does anybody know for sure?
