  • How to disable Macbook internal keyboard

    My MBP is 10.7.5. Unfortunately, the internal keyboard was spoiled by my baby.
    So here is how to disable it and use an external apple keyboard.

    Open terminal and type the following:
    sudo kextunload /System/Library/Extensions/AppleUSBTopCase.kext/Contents/PlugIns/AppleUSBTCKeyboard.kext/

    To enable it again:
    sudo kextunload /System/Library/Extensions/AppleUSBTopCase.kext/Contents/PlugIns/AppleUSBTCKeyboard.kext/

    It works like a charm!~ Googled from this link: http://forums.macrumors.com/showthread.php?t=433407

  • hard link vs symbolic link

    #####Hard link vs. Soft link in Linux or UNIX

    #####Hard links cannot link directories.
    Cannot cross file system boundaries.
    Soft or symbolic links are just like hard links. It allows to associate multiple filenames with a single file. However, symbolic links allows:

    To create links between directories.
    Can cross file system boundaries.

    #####These links behave differently when the source of the link is moved or removed.

    Symbolic links are not updated.
    Hard links always refer to the source, even if moved or removed.

    #####Link directory
    ln -s /mnt/usr/lib/* /usr/lib/
    cp -rs /mnt/usr/lib /usr/

  • How do Oracle HTTP Server and Oracle WebLogic Server work together in cluster?

    Oracle HTTP Server does not require an Oracle WebLogic domain. However,

    Oracle HTTP Server is typically used in conjunction with an Oracle WebLogic Domain.

    mod_wl_ohs links Oracle Http Server and Oracle Weblogic Server.

    In cluster, managed servers are configured together as a comma-separated list.

    in mod_wl_ohs.conf file,

    < Location /cs >
    WebLogicCluster :16200,:16200
    SetHandler weblogic-handler
    WLCookieName JSESSIONID
    < /Location >

    When the WebLogic managed server receives the request, the request is load balanced across all the cluster members.

  • Where to put google analytics?

    ###before body
    Google used to recommend putting it just before the end of body tag, but there is some loading problem of the js.

    ###before head
    Current recommendation is just before the tag.
    < head> will add a little latency; in the footer will reduce the number of pageviews recorded at some small margin.
    As a matter of personal preference, I like to include it in the

    < head>, but its really a matter of preference.
