  • Can "\Device\NamedPipe\\Win32Pipes" handles cause "Too many open files" error?

    - by Igor Oks
    Continuing from this question: When I am trying to do fopen on Windows, I get a "Too many open files" error. I tried to analyze, how many open files I have, and seems like not too much. But when I executed Process Explorer, I noticed that I have many open handles with similar names: "\Device\NamedPipe\Win32Pipes.00000590.000000e2", "\Device\NamedPipe\Win32Pipes.00000590.000000e3", etc. I see that the number of these handles is exactly equal to the number of the iterations that my program executed, before it returned "Too many open files" and stopped. I am looking for an answer, what are these handles, and could they actually cause the "Too many open files" error? In my program I am loading files from remote drive, and I am creating TCP/IP connections. Could one of these operations create these handles?

  • Sony VGN-NR260E "External Device Boot"

    - by user72158
    [A LITTLE BACKGROUND] On all modern Dell computers pushing the F12 on bios boot will allow for a screen that lets you choose what boot option you need. For example if I want to boot off of a USB flash drive to boot into a live Linux distribution in order to clean virus's on netbooks that do not have CD drives to boot from I would push F12 and choose USB device from the list of options. If this does not show up then I can always go to the F2 bios setup and choose flash drive to be the first option. When I restart the computer it will boot into the flash device. I understand that I can purchase an external USB CD drive and then boot from that. I do not want to use that option. The reason for using a flash device instead of a CD is: A: This USB flash device has several different boot OS's on it that are used. B: The antivirus disks are updated often and burning cd's and throwing away others is wasteful compared to simply updating a flash drive. There is nothing wrong with the flash drive. It works perfect on many other PC's. [PROBLEM] Booting this flashdrive has been working for years on hundreds of computers... I just have this ONE computer that I cannot figure out how to get it to boot on... I have a Sony Vaio that will not boot to this device. I've tried pushing every key combo I can think of (F12, Esc, Del, F10...) and none of these key combinations will bring up the boot menu. I chose F2 and went into the bios and changed the first boot device to USB flash device. This did not work either. There is an astrix next to the device and the note states: "This Drive is available when External Device Boot is Enable." [WHAT I NEED] I need to know How to enable External Device Boot on the Sony Vaio VGN-NR260E laptop. OR How to bring up the Boot Menu to allow me to boot off a flash device. Thanks for anyone that can help!

  • How to open a file with chinese name in python.

    - by mahendraliya
    I am trying to open a file in "w" mode with "open()" function in python. The filename is : ?????.jpg. The open function fails with this filename but succeeds with normal files. How can I open a file with names which are not in English in python? My code is as follows: try: filename = urllib.quote(filename.encode('utf-8')) destination = open(filename, 'w') yield("<br>Obtained the file reference") except: yield("<br>Error while opening the file") I always get "Error while opening the file" for non-english filenames. Thanks in advance.

  • Fiber-Optic Cable Trick Brings Remote Triggering to Older Flashes

    - by Jason Fitzpatrick
    Many older flashes lack for a jack to input a sync cable and rely exclusively on a simple slave mode triggered by the primary flash. This hack uses a piece of scrap fiber optic cable to trigger the flash in bright conditions. Using a flash as an optical slave indoors isn’t much of a problem, but if you introduce bright light (such as outdoor lighting conditions), the ambient light can overpower the small on-camera flash and render the optical slave function useless. To overcome this, Marcell over at Fiber Strobe (a blog dedicated to cataloging experiments in incorporating fiber optics into photography) came up with a simple work around. By using some foam crafting materials and tape, he whipped up a simple mount for a strand of scrap fiber optic cable to connect between the on-camera flash and the sensor on the slave flash. Once attached it works exactly like as sync cable would, except it’s transmitting a pulse of light instead of a pulse of electricity. Hit up the link below for more pictures and a build guide.

  • Why do I get a "the location is not a folder" error when trying to open files using Dash or Synapse?

    - by Christian Howd
    Within the last few days, I've encountered errors when trying to open files using Unity Dash, Synapse, or even the Gnome Search Tool. These methods will let me launch applications and folders, but not files of any time, including mp3, doc, odt, and txt. With any method, the same error dialogue results: "the location is not a folder". Is there something I can do on my end to correct this, or is this a bug in Natty that is still being corrected?

  • Why does the location of my vehicle spawner change when I open a matinee?

    - by Gareth Jones
    I'm doing work with InterActors and vehicle spawners in Unreal Tournament 3's editor, and have it set up like so: (The Walkway its on is the InterActor) However if I go in Kemsit and open the matinee that handles the InterActor, this happens: It does look to me like the editor is moving it out of the way so I can see the InterActor (which would be very clever) because only the image of the vehicle moves, not the gizmo, nor does the vehicle spawn in that location in game. Is this the case?

  • How can I limit the number of open AF_INET sockets?

    - by Stefano Palazzo
    Is there a way to limit the number of concurretly open AF_INET sockets (only)? If so, how do I do it, and how will the networking behave if I'm above the limit? For background: My cheap commodity router is a bit eager to detect 'syn flooding'. When it does, it crashes (and doesn't automatically restart itself). I'm thinking limiting concurrent connections to around 1000 should keep it from bickering.

  • Is there a way to open an "extra" temporary workspace (via terminal, preferably)?

    - by AmagicalFishy
    [Running Ubuntu 14.04, Unity] So, I have workspaces enabled and all that jazz. I know one can set some option so that Ubuntu defaults to more than four workspaces—but that's not what I want. Currently, I'd like a fifth workspace, but only temporarily (that is, I don't want it to be the default that five open. I just want it for today, and possibly w/e other day I need it). Is there a way to do this?

  • Implications of Cisco open-sourcing H.264? [on hold]

    - by Suman
    Cisco has announced that it will license and open-source the H.264 video codec. As a result of this, Firefox will be embedding H.264 playback functionality in future versions of Firefox. What implications, if any, will this have for programmers building software and/or hardware dealing with video (and WebRTC in particular)? (And if programmers.SE isn't the right forum, please feel free to suggest a better option.)

  • WebP se dote d'un mode de compression d'images sans perte, le format open source de Google veut aussi concurrencer le PNG

    WebP se dote d'un mode de compression d'images sans perte Le format open source de Google veut aussi concurrencer le PNG Mise à jour du 21 novembre 2011 Google voit grand pour son format d'image WebP et veut manifestement en faire un format à tout faire. Positionné au départ (lire ci-devant) comme un concurrent plus optimisé que le JPEG, avec en prime une couche alpha progressive (de transparence), il se dote aujourd'hui de capacités d'optimisation non destructives des images, à l'instar du PNG. Le nouveau mode lossless (sans perte) allierait densité de compression et facilité de décodage d'après un billet...

  • Un constructeur russe dévoile un modèle de Netbook sous MeeGo, une bonne nouvelle pour l'OS open-source de Intel et de Nokia

    Un constructeur russe dévoile un modèle de Netbook sous MeeGo Une bonne nouvelle pour l'OS open-source de Intel et de Nokia Quelques jours après la publication de l'interview d'un responsable d'Intel, très confiant sur l'avenir et le potentiel de MeeGo sur le long terme, un constructeur russe dévoile un modèle de Netbook embarquant cet OS. Cette machine de 10.1 pouces est baptisée « DNS » et cible essentiellement le marché local. En dehors de l'OS, sa configuration ne défraie pas la chronique. DNS est propulsé par le processeur Intel Atom N550 cadencé à 1.5 GHz et équipé d'une carte graphique Intel GMA 3150...

  • Dual monitor ATI hd 4350 (1GB PCI-e), ubuntu 12.04 (pear Linux) Do I need the ATI driver or open source?

    - by Geeve
    I think I covered it in the title, Right now both monitors are mirrored (both 19" at 1440x900). I guess what I need to know is do I need the ATI proprietary driver or will the open source driver from Ubuntu (additional drivers) work? I want to expand the desktop between the two monitors. Still finishing install and running updates now, I just wanted to gather all documentation and downloads prior to doing what is necessary. Thanks Geeve

  • Do I need to paste open source license information at the top of my webpage?

    - by Rich
    I'm developing a JavaScript application that uses several open source JavaScript projects. All their licenses have a phrase like "You must give any other recipients of the Work or Derivative Works a copy of this License". Does this mean I need to make a massive HTML comment at the top of my webpage with all the licences of the software that I use? I ask this question because I've never seen the source code of a webpage that does this.
