  • Operation System Clone from a Motherboard to Another

    - by Devian
    Lately we had an idea with my Family of building a Super Computer from Scratch. So while we were planning on building our setup, one idea came to my head that it seems possible but i want also your opinions. Lets say that we have 2 ATX Motherboards and 1 MicroATX. Motherboard Setup: 1x ASUS Rampage Extreme Black Edition 1x Intel Core i7 4960x 4x GTX Titan 8x 8GB 1866 Ram Motherboard Setup: 1x SuperMicro X9DRG-QF 2x Intel Xeon E7-8890V2 1x nVIDIA QUADRO K6000 4x nVIDIA Tesla K40 128 GB 1866 Ram And imagine a Solid State Drive with a Switch connected to both of the MotherBoards Can i edit & copy all the data of The first motherboard's RAM to The Other's to be able to continue operating my current Operation System after switching the SSD to the Second Motherboard, from the Second MotherBoard and vice versa? Les say my "Switch Application" modifies everything the Kernel needs to believe nothing happend and continuing its operation from the same point the first motherboard stopped. (Changes on the Device List, CPU Cores, Drivers... etc)

  • ffserver - streaming problem transcodation for input

    - by zozo
    Good day to all. I have a little problem. I'm trying to stream something from a cam to a server and then forward to... somewhere (it will be a site or something). On the computer that I have the cam connected to I use vlc to stream it to the server and there I try to get the stream as an input for a ffserver. The problem is that ffserver doesn't detect the input (regardless of the protocol I use (udp, rtp, etc.)). I suspect a transcoding problem or something like that but I can't find any documentation about that so... Does any1 know what transcodation I should use? Thank you for help and have a great day.

  • Weird screeching sounds coming from computer

    - by EGHDK
    My computer makes a high pitched whine noise that initially was coming from my SSD, but now I recently installed more ram into my laptop and it makes a new sounds. I don't want my ram or SSD to die on me. Are there any tests to test both of these? Again, these are really high pitched whine(y) sounds that you wouldn't hear normally, but when I'm home alone and it's silent, the noise sounds as loud as can be.

  • Capture live streaming

    - by acidzombie24
    I want to capture a rtmp stream. The videos are live, different every day and usually i cant tune in because i am busy at work doing something :(. I would like to capture the stream however they use anti capturing techniques (its live and free so i dont understand why). I tried orbit downloader without any luck. The url seems kind of weird (judging by grab++). It has || in it and other urls. What applications can i use to capture this? i am open to using linux

  • Repackage m4v file

    - by Daniel Huckstep
    I have some m4v files I made with Handbrake where the AC3 audio channel was the first one, and the stereo was the second. This causes problems with some things (like Quicktime) so I want to repackage the file such that the stereo track is the first audio track. I don't want to re-encode things. Can I do this? Can I do it for free?

  • Tomcat - Persistent Object

    - by David
    I am running a servlet that recommends items based on a data model. The data model has to be loaded into an object from a database each time user makes a request to the sever and since the data is the same for all the users I would like this object to be loaded once only. I am very new to Tomcat and don't know where to look so any advice will be appreciated. Thanks!

  • .vob to h.264 MP4 Files - Worth The Effort?

    - by harper89
    When I was doing the converting to digital format a while back I chose .VOB due to no quality loss. However recently I have been informed of this h.264 compression method. Time is not an issue here, I don't mind waiting for conversions etc. I also understand that any sort of compression will reduce quality. To test I converted a 4GB .VOB to a .mp4 using h264 in handbrake and the quality loss was very very very hard to notice. From what I have understood through research Space = .mp4(h.264) Quality = .Vob Playback = Both equally supported? But these concerns have yet to be answered: My comparison was done on a computer monitor, would the quality loss be substantially noticable if I purchased a 50 inch TV in the future? Is this type of file highly supported? (I don't want to experience incompatible players) What other issues could a conversion of files such as this cause in the future?

  • What are some good Screencasting Programs with Streaming?

    - by Joel Coehoorn
    The situation is that I work for a small college, and we have a student who will legitimately not be able to attend some classes for the next few weeks. Most of our professors use either powerpoint or a smartboard, and so we're shuffling things around so that all her classes take place in only two rooms. We want to set up those rooms to be able to live screencast (with audio) each lecture. I've seen other similar questions, but they're all more geared towards recording demos. I'm looking for something more like Live Meeting. Any suggestions appreciated.

  • X11 performance problem after upgrading from Centos3 to Centos5 with an ATI Rage XL

  • Is bigger capacity ram faster then smaller capacity ram for same clock and CL? [migrated]

    - by didibus
    I know that bigger capacity hard-drives with the same RPM are faster then smaller capacity hard-drives. I was wondering if the same is true for ram. Given two ram clocked at 1600mhz and with identical CLs: 9-9-9-24. Is a 2x8 going to perform better then a 2x4 ? Note that I am not asking if having more ram will improve the performance of my PC, I'm asking if the bigger capacity ram performs better. Thank You.

  • Episode by episode DVD Rip to AVI.

    - by ProfKaos
    I'm looking for a tool to rip DVD files to AVI files. VidCode looks cool, but it wants to convert the whole DVD (all files in the VIDEO_TS folder) to one AVI. I would like to pull each episode on the DVD to its own AVI. Is their a way to that with VidCode, or another ripper? My Plan B for VidCode is to manually separate files for each episode into their own VIDEO_TS folders. Is this possible? Is there an easy, lazy way to automate this?

  • Motherboard booting without RAM in Dimm1

    - by Jesus Ramos
    Is it possible to have a motherboard boot without placing RAM in the DIMM1 slot? Our new cooling solutions for motherboards are causing us issues where some boards that have RAM with raised heatsinks will not actually fit because the DIMM1 slot is partially blocked. Currently we mount the RAM in DIMM1 and DIMM3 because it's dual channel, are there any settings that can be changed on the BIOS to allow motherboard to boot without RAM in DIMM1 such as placing the RAM in DIMM2 and DIMM4?

  • Enable DreamScene in Any Version of Vista or Windows 7

    - by DigitalGeekery
    Windows DreamScene was a utility available for Vista Ultimate that allowed users to set video as desktop wallpaper. It was dropped in Windows 7, but we’ll take a look at how to play DreamScenes in all versions of Windows 7 or Vista. Downloading DreamScenes First, you’ll need to find some DreamScenes to download. We’ve found some nice ones at both DreamScene.org and DeviantArt. You can find those download links at the end of the article. They’ll come as compressed files, so you’ll need to extract them after downloading. Windows 7 DreamScene Activator If you are running Windows 7 you can use Windows 7 DreamScene Activator. This free portable utility enables DreamScene in both 32 & 64 bit versions of Windows 7. Users can then set either MPG or WMV files as desktop wallpaper. Download and extract the Windows 7 DreamScene Activator (link below). Once extracted, you’ll need to run the application as administrator. Right-click on the .exe and select Run as administrator. Click on Enable DreamScene. This will also restart Windows Explorer if it is open. To play your DreamScene, browse for the file in Windows Explorer, right-click the file and select Set as Desktop Background. Enjoy your new Windows 7 DreamScene.   Although it says it is for Windows 7 only, we were able to get it to work with no problems on Vista Home Premium x32 as well.   You can Pause the DreamScene at anytime by right-clicking on the desktop and selecting Pause DreamScene.   When you are ready for a change, click Disable DreamScene and switch back to your previous wallpaper. Using VLC Media Player Users of all versions of Windows 7 & Vista can enable a DreamScene using VLC. Recently, we showed you how to set a video as your desktop wallpaper in VLC.  Since DreamScenes are in MPEG or WMV format, we will use the same tactic to display them as desktop wallpaper. We’ll just need to make a few additional tweaks to the VLC settings. You’ll need to download and install VLC media player if you don’t already have it. You can find the download link below. Next, select Tools > Preferences from the Menu. Select the Video button on the left and then choose DirectX video output from the Output dropdown list. Next, select All under Show Settings at the lower left, then select the Video button on the left pane. Uncheck Show media title on video. This will prevent VLC from constantly showing the title of the video on the screen each time the video loops. Click Save and the restart VLC.   Now we will add the video to our playlist and set it to continuously loop. Select View > Playlist from the Menu. Select the Add file button from the bottom of the Playlist window and select Add file.   Browse for your file and click Open.   Click the Loop button at the bottom so the video plays in a continuous loop.   Now, we’re ready to play the video. After the video starts playing, select Video > DirectX Wallpaper from the Menu, then minimize VLC.   If you’re using Aero Themes, you may get a pop-up warning and Windows will switch automatically to a basic theme.   If looping one video gets to be a little repetitive, you can add multiple videos to your playlist in VLC and loop the entire playlist. Just make sure you toggle the Loop button on the playlist window to Loop All. Now you’ve got a nice DreamScene playing on your desktop. Another cool trick you can do with VLC is take snapshots of favorite movie scenes and set them as backgrounds. When you’re ready to go back to your old wallpaper, maximize VLC, select Video and click DirectX Wallpaper again to turn it off the video background. Occasionally we were left with a black screen and had to manually change our wallpaper back to normal even after turning off the DirectX Wallpaper. Note: Keep in mind that using the VLC method takes up a lot of resources so if you try to run it on older hardware, or say a netbook, you’re not going to get good results. We also tried to use the VLC method in XP, but couldn’t get it to work. If you have leave a comment and let us know. While the DreamScene feature never really caught on in Vista, we find them to be a cool way to pump a little life into your desktop on any version of Vista or Windows 7.

  • Architecture behind live streaming [on hold]

    - by l19
    I'm a Comp Sci undergraduate student, and I'm currently trying to understand the architecture behind streaming. I hear several terms and I'm not quite sure how they are related (e.g. streaming, broadcasting, ingesting, etc.) Is there a blog post or book that explains: How it all works in a high-level view (the workflow) The architecture (i.e. I capture content using my camera and want to display it real-time to an audience. I imagine that the content will be transferred to a server, but how does that server transmit the information to several users simultaneously?) Thanks!
