  • Full HD video playback acceleration with mplayer on Ubuntu Lucid

    - by pts
    I know that for an NVidia card I can sudo apt-get install nvidia-current mplayer, reboot, and then use mplayer -vo vdpau -vc ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau,ffh264vdpau FILE.mkv to get accelerated video playback of H.264 and other codecs, so even full HD videos can be played back with only little CPU. (And there are many other options, e.g. XBMC also supports VDPAU.) But how do I get accelerated video playback if I have a recent ATI or Intel video card on Ubuntu Lucid? How do I figure out if my video card has acceleration built in? The solution has to work with mplayer or mplayer2. It's OK for me to recompile mplayer(2), but I'd prefer installing both the kernel and the X.org X server from a binary package repository.

  • Moving files between Windows computers without creating network shares

    - by mavnn
    What's needed: To move several directories between two Windows 2008 servers on a regular basis. Due to security requirements, neither server is supposed to have network shares set up or extraneous software installed. What's available: Administrator access to both machines (including remote desktop access if that helps). A third machine with: Visual Studio 2010 Cygwin Bonus extras The script that does the rest of the work (apart from moving the files) is currently written in F#, but any .net/command line based solution would be fine.

  • Computer won't start unless power is removed for ~5 minutes

    - by Paul Tarjan
    I have a fairly standard 2-year old desktop computer (quad-core intel, single hard drive, decent video card, 300W power supply) which recently started acting up. I'm not sure what the cause is, so hopefully you can help. Sometimes (once a week-ish) I press the power button and nothing happens. No blinking, no sounds, no nothing. If I remove the power cord (or flip the switch on the power supply) I hear a capacitor discharge. If I leave it in the "no power at all" state for about 5 minutes then I can put the plug back in and the computer works perfectly. What is the issue? What do you think I have to replace?

  • Why my new GTX 660m's clock drops drastically after running few seconds

    - by trVoldemort
    I bought a Lenovo Y580 laptop few days ago, this model is equipped with GTX 660m graphics card. However, the game performance is unbelievably poor since it out from the box. I realized there is something wrong with this graphics card. I downloaded GPU-z, and did a simple test. And I was shocked by the fact that my GTX 660m graphics card is running at 135.0mhz core clock. (It should be 835mhz at least!) Even the integrated graphics card "Intel HD graphics 4000" can run at 650mhz. Further examining showed that in the first few seconds GTX 660m was actually running at 835mhz, however the core temperature quickly reached 90+°C and the clock (maybe) automatically drop to 135.0mhz. This is very strange. Anyone has any idea what's going on here?

  • Buying Video Card for 1600x900 monitor?

    - by Yar
    I just bought a monitor for a relative's computer (Intel 82915G chipset) which should produce 1600x900. Though the current card can produce 1600x1200, there's no way (that I know of) to force it to produce 1600x900. Assuming buying a card would be a solution, how would one find a cheap video card that can do 1600x900? They don't seem to list the modes in most ads. If I'm missing something in Windows, please let me know, but I've looked around quite a bit and tried many things (including unsupported resolutions, etc).

  • Configuration Tuning for PostgreSQL 9.1 PostGIS 1.5 Ubuntu 12.04 Server

    - by Martin
    My server performance is poor. At times SSH, top, and other features or commands are very slow to respond, taking several seconds or more. A query that normally takes 5 minutes can sometimes take 30 minutes. The database is mostly being used to do a spatial query (grid and summarize) on approximately 500GB of stored data spread between 4 tables. Restarting the server works as a temporary fix, but cannot be used as a long term solution. Any suggestions for how to diagnose and solve my performance issues? Hardware and Configuration: 3.3 GHz Intel quad core i5 16 GB DDR3 RAM 6 TB software RAID 10 (6 x 2 TB drives) Ubuntu 12.04 64-bit Postgres 9.1 PostGIS 1.5

  • How to combine designable components with dependency injection

    - by Wim Coenen
    When creating a designable .NET component, you are required to provide a default constructor. From the IComponent documentation: To be a component, a class must implement the IComponent interface and provide a basic constructor that requires no parameters or a single parameter of type IContainer. This makes it impossible to do dependency injection via constructor arguments. (Extra constructors could be provided, but the designer would ignore them.) Some alternatives we're considering: Service Locator Don't use dependency injection, instead use the service locator pattern to acquire dependencies. This seems to be what IComponent.Site.GetService is for. I guess we could create a reusable ISite implementation (ConfigurableServiceLocator?) which can be configured with the necessary dependencies. But how does this work in a designer context? Dependency Injection via properties Inject dependencies via properties. Provide default instances if they are necessary to show the component in a designer. Document which properties need to be injected. Inject dependencies with an Initialize method This is much like injection via properties but it keeps the list of dependencies that need to be injected in one place. This way the list of required dependencies is documented implicitly, and the compiler will assists you with errors when the list changes. Any idea what the best practice is here? How do you do it? edit: I have removed "(e.g. a WinForms UserControl)" since I intended the question to be about components in general. Components are all about inversion of control (see section 8.3.1 of the UMLv2 specification) so I don't think that "you shouldn't inject any services" is a good answer. edit 2: It took some playing with WPF and the MVVM pattern to finally "get" Mark's answer. I see now that visual controls are indeed a special case. As for using non-visual components on designer surfaces, I think the .NET component model is fundamentally incompatible with dependency injection. It appears to be designed around the service locator pattern instead. Maybe this will start to change with the infrastructure that was added in .NET 4.0 in the System.ComponentModel.Composition namespace.

  • Stuttery 1080p playback on decent system

    - by Leo
    We have a media center system that was recently built. It works well for all types of content, however it has issues with 1080p content. 720p plays fine. I have tried VLC, ffdshow and finally, CoreAVC. CoreAVC plays the best however it still eventually loses sync due to stutter - this does not happen on other systems with the same file. Specs: Asrock 4core-2dual sata PCI Express ATI 2400 HD 1.5GB DDR 2100 Intel Pentium E5300 120GB Maxtor Diamondmax PATA Any ideas?

  • Does dual-channel work only with an even number of RAM sticks?

    - by iconiK
    I have noticed that on the ASUS P5QL Pro motherboard the BIOS says "Dual Channel Asymmetric Mode" during POST. The motherboard has three 2GB Kingston ValueRAM 800 MHz DIMMs populated in the first 3 slots from the CPU socket. I have not run any benchmarks to verify that dual-channel is somehow being used, but I believed that dual-channel has to have an even number of sticks (and for triple channel, a multiple of 3). Another example is the Intel DX58SO motherboard; it has four DIMM slots, yet it's an LGA 1366 motherboard which does triple-channel. Apparently triple-channel still works with four DIMMs, instead of falling back to dual-channel. What does the BIOS' POST message mean in those case? Is dual-channel really used for the first two DIMMs, with the other one being an odd one in single-channel mode?

  • The concept of an Intent in Android?

    - by Mohit Deshpande
    I don't really understand the use and concept of an Intent. I DO understand that an activity are one visual interface and one endeavour that the user can partake in. I THINK an intent is used to launch and communicate between different activities. If so, then how would you accomplish that? A code sample would be helpful.

  • Is there a way to get a larger desktop than the screen?

    - by Cajuntechie
    Is there any freeware out there that will allow me to run the desktop that is larger than the resolution of the screen? My situation: Win XP, Dell Mini 10, iirc- Intel GMA950 I need to use a netbook for one specific web site (with firefox) that doesn't render properly if the screen isn't at least 1024x768. It is a netbook, so the res is 1024x600. Is there anything out there that will allow me to use a 1024x768 desktop on this smaller screen WITHOUT shrinking the desktop to fit. I want to pan around. Thanks! Cajuntechie

  • IBM laptop remove access-connections

    - by Kevin
    I installed IBM Access Connections on my IBM t61 laptop to manage my wireless connections but it simply will not connect to my network. I want to uninstall it and try the Intel software which is capable to performing the same task. However, when I go into "Control Panel" - "Add/Remove Programs" and try to "Remove" this package, it simply opens up a screen and closes it immediately. This happens too fast for me to see whether its an error. Has anyone encountered this issue ? The event logs do not show any error.

  • How to inherit constructors with arguments in .NET?

    - by Soumya92
    I have a "MustInherit" .NET class which declares a constructor with an integer parameter. However, Visual Studio gives me an error when I create any derived class stating that there is no constructor that can be called without any arguments. Is it possible to inherit the constructor with arguments? Right now, I have to use Public Sub New(ByVal A As Integer) MyBase.New(A) End Sub in the derived classes. Is there any way to avoid this?

  • Linux Defualt Startup Display PCI to fix black boot screen

    - by Jonathan
    You heard it all before black screen on boot after perfectly fine install of most linux ubnuntu mint etc distributions (the netbook works fine) It has an Intel N10 integrated graphics chipset. I have actually found that if I plug in an external display then remove it the default screen turns on and my laptop works fine drivers all great - I have tried the screen cycle button fn f7 but doesn't work when no display is plugged in. It also works out all the correct resolutions and no modification of the grub bootloader or creating any xorg configs. So I think my monitor is forcing to a display that doesn't exist. Do you know if there is anyway I can force it to choose a different screen at boot so I can get a login screen? I can use nomodeset on grub but xrandr cant add the damned 1024 600 60 resolution that I need! Ideas guys?

  • MS Runtime required for app to run, how can I include with setup?

    - by JPJedi
    My application requires access to be installed on the computer or at least the MS Access runtime. Is their a way to include that with the application to check for that component/resource or install it if it isn't? Or would it just be easier to include a link to tell the user where to get the runtime if the error happens? I am using Visual Studio 2008 and the windows form app is written in VB.net. I am currently using click once for the deployment. Thanks

  • update ocz vertex le capacity via firmware update

    - by Ben Voigt
    I have an OCZ Vertex LE 100GB drive. It's actually 128GiB of NAND flash, with a whopping 28%+ reserved for write combining. Most 128GiB drives are actually ~ 115GB usable (and marketed as 120GB or 128GB). There were rumors that the reserved fraction could be decreased on OCZ 100GB drives. Can anyone provide a link to firmware that does that, or an official statement that no such firmware exists? (NB: I recently installed the 1.24 firmware from the OCZ site, it didn't affect the capacity. Possibly because the rumors say the capacity change is destructive to existing content.) Of possible interest: flashing firmware was more of a pain than it should have been -- the tool didn't detect the disk until I booted an older Windows install off a secondary hard disk, I suspect the Intel SATA driver is the issue and tool only works with the msachi.sys driver.
