  • Hiding part of a page from Search Server 2010 Express

    - by Jonathan
    I'm working on a soon-to-be-public-facing site, and we want to have our search live on day 1, and want it to be searchable but non-public during testing, so we're planning to use something whose crawling we can control -- Search Server 2010 Express. However, if I search for something in my top navigation bar, I get nearly every page as a hit. It kinda makes sense, as every page has that content, but it's completely irrelevant on most pages. I want it to crawl through my navigation, but ignore the text within the navigation for search results. I was hoping that it'd just figure that out on it's own (the HTML for the top nav is static), but it's apparently not. Is there some standard thing I can put in my HTML that will achieve the effect I'm going for? On a side note: when I go live, will I have the same problem with public search engines, or do they tend to be smarter?

  • In a virtual machine monitor such as VMware’s ESXi Server, how are shadow page tables implemented?

    - by ali01
    My understanding is that VMMs such as VMware's ESXi Server maintain shadow page tables to map virtual page addresses of guest operating systems directly to machine (hardware) addresses. I've been told that shadow page tables are then used directly by the processor's paging hardware to allow memory access in the VM to execute without translation overhead. I would like to understand a bit more about how the shadow page table mechanism works in a VMM. Is my high level understanding above correct? What kind of data structures are used in the implementation of shadow page tables? What is the flow of control from the guest operating system all the way to the hardware? How are memory access translations made for a guest operating system before its shadow page table is populated? How is page sharing supported? Short of straight up reading the source code of an open source VMM, what resources can I look into to learn more about hardware virtualization?

  • Ajax page.replace_html problems with partials in Rails

    - by Chris Power
    Hello, I am having a problem with a pretty simple AJAX call in rails. I have a blog-style application and each post has a "like" feature. I want to be able to increment the "like" on each post in the index using AJAX onclick. I got it to work; however, the DOM is a bit tricky here, because no matter what partial its looking at, it will only update the TOP partial. so if I click "like" on post #2, it will update and replace the "likes" on post #1 instead. Code for _post partial: <some code here...> <div id="postcontent"> Posted <%= post.created_at.strftime("%A, %b %d")%> <br /> </div> <div id="postlikes"> <%= link_to_remote 'Like', :url => {:controller => 'posts', :action => 'like_post', :id => post.id}%> <%= post.like %> </div> code for _postlikes partial: <div id="postlikes"> <%= link_to_remote 'Like', :url => {:controller => 'posts', :action => 'like_post', :id => @post.id}%> <%= @post.like %> </div> </div> like_post.rjs code: page.replace_html "postlikes", :partial => "postlikes", :object => @post page.visual_effect :highlight, "postlikes", :duration => 3 So this all works properly for the first "postcontent" div. But this is an index of posts, so if I wanted to updated the second "postcontent" div on the page, it will still replace the html of the first. I understand the problem, I just don't know how to fix it :) Thanks in advance!

  • C++ assignment - stylish or performance?

    - by joejax
    Having been writing Java code for many years, I was amazed when I see this C++ statement: int a,b; int c = (a=1, b=a+2, b*3); My question is: Is this a choice of coding style, or it has real benefit? (looking for a practicle use case) I think the compiler will see it the same as following: int a=1, b=a+2; int c = b*3; (What's the offical name for this? I assume it's a standard C/C++ syntax.)

  • How to display model popup at first time page load only

"true" : "false" %>'; if (chkPostBack == 'false') { var popup = $find('ModalPopupExtender1'); if (popup != null) { popup.show(); } } } I got the following error, Please help me. The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

  • Static method,new thread performance question

    - by ylazez
    Hey guys i just have two questions about two methods used in many controllers/servlets in my app: 1-what is the difference between calling a static method in a util class or a non static method (like methods dealing with dates i.e getting current time,converting between timezones), which is better ? 2-what is the difference between calling a method(contain too many logic like sending emails) in the controller directly or running this method in a different thread ?

  • video player for HTML 5 page not loading

    - by philippe
    I'm using VideoJS to as my video player for a project I've been working on. Basically I have a div, and I wanted to have the video player within that div, however when I load the page nothing happens, and the video is never played. In fact, the video is never loaded nor shown in the page. I basically copied the example from VideoJS' page. Any thoughts? <div class="video-js-box"> <!-- Using the Video for Everybody Embed Code http://camendesign.com/code/video_for_everybody --> <div style="position: absolute; top: 50px; left: 600px; display:none"> <video id="example_video_1" class="video-js vjs-default-skin" controls preload="auto" width="640" height="264" poster="http://video-js.zencoder.com/oceans-clip.png" data-setup='{"example_option":true}'> <source src="http://video-js.zencoder.com/oceans-clip.mp4" type='video/mp4'></source> <source src="http://video-js.zencoder.com/oceans-clip.webm" type='video/webm'>></source> <source src="http://video-js.zencoder.com/oceans-clip.ogv" type='video/ogg'></source> </video> <!-- Download links provided for devices that can't play video in the browser. --> <p class="vjs-no-video"><strong>Download Video:</strong> <a href="http://video-js.zencoder.com/oceans-clip.mp4">MP4</a>, <a href="http://video-js.zencoder.com/oceans-clip.webm">WebM</a>, <a href="http://video-js.zencoder.com/oceans-clip.ogv">Ogg</a><br> <!-- Support VideoJS by keeping this link. --> <a href="http://videojs.com">HTML5 Video Player</a> by VideoJS </p> </div> <div style="clear:both;"></div> </div><!--main-->

  • Validation against 10K XSD - performance problem

    - by stck777
    I have an XSD scheme which has 10K lines. It takes 5 seconds to validate my XML with 500 lines. I get dynamically XML via POST from external server, on every click of the user on my homepage. The validation takes 5+ seconds, which is very much for every click of the user. PHP Example: $doc = new DOMDocument(); $doc->load('file.xml'); //100 to 500 lines $doc->schemaValidate('schema.xsd'); //schema.xsd 10 000 lines Do you have any idea how I can validate the XML against the XSD faster?

  • Triggering jquery event function at page load

    - by lazysoundsystem
    Here's a little jQuery function that does what I want when a checkbox is clicked, but I have a basic gap in my knowledge: How to register this so that it deals with checkboxes that are already clicked when the page loads? $(document).ready(function() { $('fieldset input:checkbox').click(function() { if ($(this).attr('name') == 'foo') { // hide checkbox 'bar' } else { // show checkbox 'bar' } } }); If I use .trigger('click'), it clicks (or unclicks) all the boxes on page load. I can think of a few ways to do this that would involve repeating portions of the code, but I just know that jQuery already has an elegant answer for this...

  • Google App Engine, Java, and HTTP Performance

    - by polyclef
    A friend and I are currently working on a turn-based game with chat with both desktop browser and Android clients, with Google App Engine as the server. We're using the Java API for GAE and using HTTP for communication with the server. We've implemented simple chat functionality, and we're getting undesirable latencies 1-3 seconds from both the browser and Android clients while just posting simple one-word chat messages. My friend thought it would be best to use XMPP instead of HTTP, but we want to use a Google Accounts cookie for authentication from the Android client, and according to the GAE documentation, XMPP clients cannot use a Google Accounts cookie and must use the user's password. Does anyone have any suggestions as to where the latency might be coming from, how to troubleshoot it, and/or what to do about it? Also, is anyone aware of any opensource implementations of chat (or something similar) on GAE done in Java? Can't seem to find any.

  • Asychronous page update with ASP.NET MVC

    - by Graham
    Hi, I'm learning ASP.NET MVC 1.0 and need to implement an asynchronous/dynamic page update. I'm new to MVC and jQuery so I'm not sure what to look for. What I want to do is to allow a user to start a monitoring a domain layer function (similar to a news ticker) and then do a partial page update based on the continously changing results. In ASP.NET I'd do this with a javascript timer to cause a postback, and an AJAX update panel..... but this seems a bit "hacky" for ASP.NET MVC. Is there a better way?

  • Getting content of a Facebook page in Adobe Flex

    - by cuneyt
    Hi guys, I wrote a Flex application that sends a UrlRequest to Facebook and gets the content of page as a string. The application user clicks a button, and the application connects to Facebook. And no I do not mean using Facebook API. It is like a screen scraper. This application worked locally, but when deployed to server it gives a sandbox security error. I have my crossdomain.xml on the root, but I think the problem is not that. Not only Facebook, but I cannot get any web site when the application is deployed on server. What should I do to get the content of a remote web page?

  • Future of IE9: Opacity + Performance

    - by chris_l
    I just tried the IE9 "Second Internet Explorer Platform Preview" - which supports CSS opacity now. That's nice, but I tried it with one of my website prototypes, and it's quite slow when scrolling etc. Admittedly, the prototype uses hundreds of images with opacity != 1, but everything is snappy with current versions of Firefox, Safari, Chrome and Opera. Does anybody know, if there are plans for IE9 to become faster in this area? Even rumours about this would be interesting in this case.

  • Peoplesoft queries - performance

    - by DBa
    Hi, I'm facing a problem with PeopleSoft queries (using Oracle backend database): when a rather complex query involving multiple records is set off by a user, PS does an enforced join of security records, thus producing SQL like this: select .... from ps_job a, PS_EMPL_SRCQRY a1, ps_table2 b, ps_sec_rcd2 b1, ps_table3 c, ps_sec_rcd3 c1 where (...security joins a-a1, b-b1, c-c1...) and (...joins of a, b and c...) and a.setid_dept = 'XYZ'; (let's assume the last condition has a high selectivity and there is an index on the column) Obviously, due to the arrangement of the conditions, first a huge join is created, written to the temp segment, and when the last condition is finally applied, only a small subset is selected. A query formulated in this way is very likely to hit the preset timeout of the APPSRV, and even of the QRYSRV. When writing the query manually, I would rather move the most selective condition to the start, thus limiting the amount of the data being handled, to a considerable level. Any ideas on how to make PS behave like this? Actually, already rewriting "Oracle-styled" SQL to ANSI SQL seems to accelerate the queries - however, PS writes Oracle-style queries... Thanks in advance DBa

  • Worried about spiders repeatedly hitting high-demand page

    - by Matt Thrower
    Due to some rather bizarre architectural considerations I've had to set up something that really ought to run as a console application as a web page. It does the job of writing a large variety of text files and xml feeds from our site data for various other services to pick up so obviously it takes a little while to run and is pretty processor intensive. However, before I deploy it I'm rather worried that it might get hit repeatedly by spiders and the like. It's fine for the data to be re-written but continual hits on this page are going to trigger performance issues for obvious reasons. Is this something I ought to worry about? Or in reality is spider traffic unlikely to be intensive enough to cause problems?

  • How is the Trac Project List page customised?

    - by CnTwo
    We've been using Trac for a while now for our developers only. However we are now opening it up for our (internal) clients. We have a project listing page (based on the default one that comes with Trac). What we'd like to do, is display more information about the project than what is currently available. I have searched google and here, to see if I can find how to get more information. There seems to be a variable called $project which has .name, .description and .href as attributes. Is there somewhere, a list of the attributes available? Or perhaps a different solution altogether that will allow us to display more information on the project list page. Such as the number of open tickets etc.

  • prevent form from automatically re-submitting on page load

    - by user323774
    I am using jQuery to point a form's target to an iframe on .submit(). This is to upload a file. It works fine, but when the page reloads, and the iframe is appended to the DOM, the iframe automatically resubmits the form, causing the same file to be sent to the server on each page load. If I do not include the iframe in the HTML markup, or do not append it to the DOM, this doesn't happen, but of course, I need the iFrame. So my question is, how can i prevent this? :) Andrew

  • ASP.Net: Expiring a page when navigating back

    - by K2so
    Basically all pages on this site I am building cannot be accessed when the user clicks on "Back" (or with key control) in the browser, and the page should expire if one is trying to navigate back in history. I put into Global.asax::Application_BeginRequest Response.Cache.SetCacheability(HttpCacheability.NoCache) Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1)) Response.Cache.SetValidUntilExpires(False) Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches) Response.Cache.SetNoStore() This would clear out the cache and disallow going back to any pages when the user is logged out, but doesn't do the job while the user is logged in. I saw posts where people suggested using a javascript approach, by calling History.Forward(1) on the page. But I wouldn't like to do this, as it will require javascript enabled to work (which user can disable). Appreciate any suggestions.

  • Network Bypass - PC Registration Page - I'm trying to bypass a college Registration Page so I can ac

    - by Kamron3
    What I'm trying to do: Connect to the internet without registering But! Here's my problem: I can't connect. I used to be able to, now when I try to connect it says "Server not found." I can connect just fine on my other Laptop. I did a test as well. I used a LAN USB adapter and could connect fine, then now I can't connect again. Possibly because I am using uTorrent to download stuff, but I want to connect again Is there anyway I can use some sort of "virtual adapter"-type of connection where it masks my actual adapter? How can I connect to the connection without having to buy more and more Network USB Adapters? Thanks much!

  • vb.net more performance for moving objects

    - by René
    I have the mission to make a small game for a school project. Pictures boxes, moved by a timer for walking enemies.If there are around 5 or 6 moving picture boxes at the form, my application get troubles and lags. After I kill some enemies (remove them from the Controls Collection of the Form/Panel) It come back smooth. I think the loop of the enemy movement is too complicated but I don't know how to make that simpler. Private Sub TimerEnemyMovement_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TimerEnemyMovement.Tick For Each Enemy As Control In PanelBackground.Controls If Enemy.Name.Substring(0, 5) = "Enemy" Then _enemy.MoveEnemy(Enemy, 2) End If Next End Sub I also thought about Multithreading but not sure this would solve the problem and there is also the problem that I can't access the Controls of my mainform. You see, I don't have much knowledge about vb.net Any ideas how to fix that lag?

    I have two applications, one of which is a store and is located under the virtual directory "store", while the main "application" is the parent website/application. However, when visiting the the top-level website address, I would like to start people in /store/default.aspx (technically "/store/home") but this is not allowed in the entry box in IIS. Currently I am doing the redirect manually in code, but was wondering if there was a way to do this in IIS or something. Thanks for any help.

  • Getting All categories in external page.

    - by Harsha
    This is very basic magento question i guess. I want to first get all the store categories, then loop through them to get their sub-categories and products and similarly continue till the last sub-category. I will be using this in an external page having Mage::app() declared at the top of the page. I am not aware of the Magento API's(if thats wat they are called) to use to get this functionality. Remember I am not using this in any of the templates, so something like getCurrentCategory() will not work here i guess. Also please guide if there are any good resources to search for particular functionality in magento and API's to implement it, or am i doomed to go through their phpdoc to know the list of methods. Any help here will be greatly appreciated, Thanks.
