I like it but I find it complicated and I have been trying to download and every time I try to install something an error comes up Archive: /home/singh/Downloads/Shockwave_Installer_Full.exe [/home/singh/Downloads/Shockwave_Installer_Full.exe] End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. zipinfo: cannot find zipfile directory in one of /home/singh/Downloads/Shockwave_Installer_Full.exe or /home/singh/Downloads/Shockwave_Installer_Full.exe.zip, and cannot find /home/singh/Downloads/Shockwave_Installer_Full.exe.ZIP, period.

  • C# timer getting fired before their interval time

    - by Swati Ghaisas
    Hi, We're getting following problem while using system.threading.timer ( .net framework 2.0 ) from a Windows service. There are around 12 different timer objects.. Each timer has due time and interval. This is set correctly. It is observed that after 3 to 4 hours, the timers start signalling before their interval elapses. For example if the timer is supposed to signal at 4:59:59, it gets signalled at 4:59:52, 7 seconds earlier. Can someone tell me what is the cause for this behavior and what is the solution for that ? Thanks, Swati

  • Question regarding Manifest in Java jar file

    - by Tara Singh
    Hi All, Is is mandatory to have classpath inside a Manifest file inside the java jar file? can we do work without having the classpath inside it? The reason why I am asking this is because I have a jar file for a server application. When I tried to connect many connections with Server, Server went down and the error was "Too many open files", when searched about it, I found one Sun Bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6446657 . Then I checked and i was having a classpath entry in the Jar file. So this question arises. Thanks, Tara Singh

  • How does an optimizing compiler react to a program with nested loops?

    - by D.Singh
    Say you have a bunch of nested loops. public void testMethod() { for(int i = 0; i<1203; i++){ //some computation for(int k=2; k<123; k++){ //some computation for(int j=2; j<12312; j++){ //some computation for(int l=2; l<123123; l++){ //some computation for(int p=2; p<12312; p++){ //some computation } } } } } } When the above code reaches the stage where the compiler will try to optimize it (I believe it's when the intermediate language needs to converted to machine code?), what will the compiler try to do? Is there any significant optimization that will take place? I understand that the optimizer will break up the loops by means of loop fission. But this is only per loop isn't it? What I mean with my question is will it take any action exclusively based on seeing the nested loops? Or will it just optimize the loops one by one? If the Java VM complicates the explanation then please just assume that it's C or C++ code.

  • Stretch in multiple components using af:popup, af:region, af:panelTabbed

    - by Arvinder Singh
    Case study: I have a pop-up(dialogue) that contains a region(separate taskflow) showing a tab. The contents of this tab is in a region having a separate taskflow. The jsff page of this taskflow contains a panelSplitter which in turn contains a table. In short the components are : pop-up(dialogue) --> region(separate taskflow) --> tab --> region(separate taskflow) --> panelSplitter --> table At times the tab is not displayed with 100% width or the table in panelSplitter is not 100% visible or the splitter is not visible. Maintaining the stretch for all the components is difficult......not any more!!! Below is the solution that you can make use of in many similar scenarios. I am mentioning the major code snippets affecting the stretch and alignment. pop-up: <af:popup> <af:dialog id="d2" type="none" title="" inlineStyle="width:1200px"> <af:region value="#{bindings.PriceChangePopupFlow1.regionModel}" id="r1"/> </af:dialog> The above region is a jsff containing multiple tabs. I am showing code for a single tab. I kept the tab in a panelStretchLayout. <af:panelStretchLayout id="psl1" topHeight="300px" styleClass="AFStretchWidth"> <af:panelTabbed id="pt1"> <af:showDetailItem text="PO Details" id="sdi1" stretchChildren="first" > <af:region value="#{bindings.PriceChangePurchaseOrderFlow1.regionModel}" id="r1" binding="# {pageFlowScope.priceChangePopupBean.poDetailsRegion}" /> This "region" displays a .jsff containing a table in a panelSplitter. <af:panelSplitter id="ps1"  orientation="horizontal" splitterPosition="700"> <f:facet name="first"> <af:panelHeader text="PurchaseOrder" id="ph1"> <af:table id="md1" rows="#{bindings.PurchaseOrderVO.rangeSize}" That's it!!! We're done... Note the stretchChildren="first" attribute in the af:showDetailItem. That does the trick for us. Oracle docs say the following about stretchChildren :  Valid Values: none, first The stretching behavior for children. Acceptable values include: "none": does not attempt to stretch any children (the default value and the value you need to use if you have more than a single child; also the value you need to use if the child does not support being stretched) "first": stretches the first child (not to be used if you have multiple children as such usage will produce unreliable results; also not to be used if the child does not support being stretched)

  • Authorship tag or Customer reviews to enhance click-through rate

    - by Prashant Singh
    I was first using authorship tag on all the pages of my website. That gave me a pretty decent improvement in the click through rate. However, I have recently added ratings on my website, i.e. all my pages are being rated by the readers and the same has been made available to Google via rich snippets. The result being the image of the author from the google search results has been removed. It shows ratings given by the customers and just writes the name of the author. What will be its impact on the click-through rate ? Is it OK to have the ratings or should I switch back to only authorship tag as I was using in the past ? Please comment if I am unclear in asking my problem. Thanks :)
