• Load dll's from Environment Variable Path from a service

  - by Paulo Manuel Santos

  We install Matlab Runtime on a machine, then we restart a .net windows service that invokes methods from the Matlab Runtime. The problem is that we receive TypeInitializationException errors until we restart windows. We think this happens because Environment Variables are not changed on services until restart and Matlab uses the %Path% variable to reference it's core DLL's. My question is, do you think I can change the %Path% variable so that Matlab will use it when referencing the core dll's for it's engine? Or is it possible to add a directory to the runtime DLL loading mechanism of .NET so that those Matlab core dll's would be referenced correctly without restarting the machine? Here is the exception we get System.TypeInitializationException: The type initializer for 'MatlabCalculation.Calculation' threw an exception. ---> System.TypeInitializationException: The type initializer for 'MathWorks.MATLAB.NET.Utility.MWMCR' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'mclmcrrt710.dll': Kan opgegeven module niet vinden. (Exception from HRESULT: 0x8007007E) at MathWorks.MATLAB.NET.Utility.MWMCR.mclmcrInitialize() at MathWorks.MATLAB.NET.Utility.MWMCR..cctor() --- End of inner exception stack trace --- at MatlabCalculation.Calculation..cctor() --- End of inner exception stack trace --- at MatlabCalculation.Calculation.Finalize() "Kan opgegeven module niet vinden" = "The specified module not found"

• JQuery Simplemodal and Tabs Help Needed

  - by Dave R

  Hi, I've got an asp.net page containing a Textbox with an Autocomplete extender on it. It's setup so the user can type a short reference code into the textbox and then choose from the list of matching codes returned by the autocomplete. On the "select", I then call the server using JQuery. I'm currently using $.get here.... The callback function from $.get checks for "success" and then displays a simple-modal dialog containing info about the item they've just selected. if (sStatus == "success") { $.modal(sText, { overlayClose: true, appendTo:'form', onShow: function(dialog) { $("#ccTargets_tabContainer").tabs(); }, onClose: function(dialog) { $("#<%=TextBox1.ClientID%>").val(""); $.modal.close(); } }); $.ready(); } One of the bits of info being loaded here is a JQuery TABS setup, so the onShow function of the simplemodal is used to initiate the tabs which are within the simplemodal. Now to the crux of my problem. If I do multiple consecutive "autocompletes" on the same page it all works fine Unless I have selected a different tab on the tabs in the simplemodal ....If I select a different tab, close the simplemodal and then do another autocomplete I get a JQuery error which seems to relate to a selector doing something with the "old" selected tab that was on the "closed" modal. I'm clearly missing some sort of cleardown / initialisation somewhere, but can't find what it is. Help? I've tried "tabs.destroy" before the modal call in the code above and I've tried a $.ready() call as indicated too.... UPDATE: Is it something to do with JQuery Tabs appending my addressbar URL with the selected tab's ID?

• jquery slide toggle divs without creating multiple classes, functions, etc... ui accordion

  - by SPE

  Greetings, based on the jquery ui accordion I'm using, I have added a slide toggle to my accordion list items. so what happens is I click on an li and a div slides down underneath to reveal more content. The issue I'm having is that I find myself having to create multiple id's to reference the slidetoggle. example of the div id css: #panel, #panel2, #panel3, #panel4, etc.... the Is there a way I can use the slide toggle without having to adding another number so it will slide? I have 50 list items I'm using: Here's a sample of the js (as you can see where I'm going with this): $(".btn-slide").click(function(){ $("#panel").slideToggle("slow"); $(this).toggleClass("active"); return false; }); $(".btn-slide2").click(function(){ $("#panel2").slideToggle("slow"); $(this).toggleClass("active"); return false; }); sample html: <li><div class="slide"><a href="#" class="btn-slide">One</a></div><div id="panel"></div></li> <li><div class="slide"><a href="#" class="btn-slide2">Two</a></div><div id="panel2"></div></li>

• Method for finding memory leak in large Java heap dumps

  - by Rickard von Essen

  I have to find a memory leak in a Java application. I have some experience with this but would like advice on a methodology/strategy for this. Any reference and advice is welcome. About our situation: Heap dumps are larger than 1 GB We have heap dumps from 5 occasions. We don't have any test case to provoke this. It only happens in the (massive) system test environment after at least a weeks usage. The system is built on a internally developed legacy framework with so many design flaws that they are impossible to count them all. Nobody understands the framework in depth. It has been transfered to one guy in India who barely keeps up with answering e-mails. We have done snapshot heap dumps over time and concluded that there is not a single component increasing over time. It is everything that grows slowly. The above points us in the direction that it is the frameworks homegrown ORM system that increases its usage without limits. (This system maps objects to files?! So not really a ORM) Question: What is the methodology that helped you succeed with hunting down leaks in a enterprise scale application?

• Does replace into have a where clause?

  - by Lajos Arpad

  I'm writing an application and I'm using MySQL as DBMS, we are downloading property offers and there were some performance issues. The old architecture looked like this: A property is updated. If the number of affected rows is not 1, then the update is not considered successful, elseway the update query solves our problem. If the update was not successful, and the number of affected rows is more than 1, we have duplicates and we delete all of them. After we deleted duplicates if needed if the update was not successful, an insert happens. This architecture was working well, but there were some speed issues, because properties are deleted if they were not updated for 15 days. Theoretically the main problem is deleting properties, because some properties are alive for months and the indexes are very far from each other (we are talking about 500, 000+ properties). Our host told me to use replace into instead of deleting properties and all deprecated properties should be considered as DEAD. I've done this, but problems started to occur because of syntax error and I couldn't find anywhere an example of replace into with a where clause (I'd like to replace a DEAD property with the new property instead of deleting the old property and insert a new to assure optimization). My query looked like this: replace into table_name(column1, ..., columnn) values(value1, ..., valuen) where ID = idValue Of course, I've calculated idValue and handled everything but I had a syntax error. I would like to know if I'm wrong and there is a where clause for replace into. I've found an alternative solution, which is even better than replace into (using simply an update query) because deletes are happening behind the curtains if I use replace into, but I would like to know if I'm wrong when I say that replace into doesn't have a where clause. For more reference, see this link: http://dev.mysql.com/doc/refman/5.0/en/replace.html Thank you for your answers in advance, Lajos Árpád

• Looking for an elegant appwidget skin solution

  - by sam-henwood

  I have an appwidget application and would like to enable users to create skins which can be applied at runtime. My preferred solution is to use apk files with nine patch png images that stretch to fit the ImageView's of widget, however its starting to look like I might have to use another packaging technique (e.g. zip files). What I've tried: Importing nine patch resources as Drawable with context.getResourcesForApplication(my.app).getResources..., converting them to bitmaps using a canvas and setting the bitmap to the RemoteView using setImageViewBitap. This didn't work because I needed to specify the size of the resulting view (myBitmap.setBounds(..,..)) during conversion and some of the widths/heights in my appwidget aren't fixed. Perhaps there is a way to get the heights etc that I missed. Importing resources directly to the RemoteView using setImageViewUri() This doesn't work because the function doesn't seem to read android.resource:// Uri's anymore (I poked around in the ImageView source and it only seems to read files paths and content:// Uri's) Importing resources directly to the RemoteView using setImageViewResource() which didn't work because the id retrieved from the external package obviously doesn't include a package reference. What I'm trying to avoid is hard coding all my appwidget width's and height's, or using a separate packaging scheme. Has anyone implemented appwidget skins nicely and want to share the knowledge? Alternately there might be a hole in my logic somewhere that can be pointed out. I can provide code if required though I don't have any here right now.

• C# - update variable based upon results from backgroundworker

  - by Bruce

  I've got a C# program that talks to an instrument (spectrum analyzer) over a network. I need to be able to change a large number of parameters in the instrument and read them back into my program. I want to use backgroundworker to do the actual talking to the instrument so that UI performance doesn't suffer. The way this works is - 1) send command to the instrument with new parameter value, 2) read parameter back from the instrument so I can see what actually happened (for example, I try to set the center frequency above the max that the instrument will handle and it tells me what it will actually handle), and 3) update a program variable with the actual value received from the instrument. Because there are quite a few parameters to be updated I'd like to use a generic routine. The part I can't seem to get my brain around is updating the variable in my code with what comes back from the instrument via backgroundworker. If I used a separate RunWorkerCompleted event for each parameter I could hardwire the update directly to the variable. I'd like to come up with a way of using a single routine that's capable of updating any of the variables. All I can come up with is passing a reference number (different for each parameter) and using a switch statement in the RunWorkerCompleted handler to direct the result. There has to be a better way. Thanks for your help.

• How do I know if I have an unmanaged resource?

  - by Shiftbit

  I've read that unmanaged resource are considered file handles, streams, anything low level. Does MSDN or any other source explain how to recognize an unmanaged resource? I can't seem to find any examples on the net that show unmanaged code, all the examples just have comments that say unmanaged code here. Can someone perhaps provide a realworld example where I would handle an unmanaged resources in an IDispose interface? I provided the IDisposable interface for your convience. How do I identify an unmanaged resource? Thanks in advance! IDisposable Reference Public Class Sample : Implements IDisposable Private disposedValue As Boolean = False 'To detect redundant calls ' IDisposable Protected Overridable Sub Dispose(ByVal disposing As Boolean) If Not Me.disposedValue Then If disposing Then ' TODO: free other state (managed objects). End If ' TODO: free your own state (unmanaged objects). ' TODO: set large fields to null. End If Me.disposedValue = True End Sub ' This code added by Visual Basic to correctly implement the disposable pattern. Public Sub Dispose() Implements IDisposable.Dispose ' Do not change this code.

• Spring-hibernate mapping problem

  - by James

  I have a spring-hibernate application which is failing to map an object properly: basically I have 2 domain objects, a Post and a User. The semantics are that every Post has 1 corresponding User. The Post domain object looks roughly as follows: class Post { private int pId; private String attribute; ... private User user; //getters and setters here } As you can see, Post contains a reference to User. When I load a Post object, I want to corresponding User object to be loaded (lazily - only when its needed). My mapping looks as follows: <class name="com...Post" table="post"> <id name="pId" column="PostId" /> <property name="attribute" column="Attribute" type="java.lang.String" /> <one-to-one name="User" fetch="join" class="com...User"></one-to-one> </class> And of course I have a basic mapping for User set up. As far as my table schema is concerned, I have a table called post with a foreign UserId which links to the user table. I thought this setup should work, BUT when I load a page that forces the lazy loading of the User object, I notice the following Hiberate query being generated: Select ... from post this_ left outer join user user2_ on this.PostId=user2_.UserId ... Obviously this is wrong: it should be joining UserId from post with UserId from user, but instead its incorrectly joining PostId from post (its primary key) with UserId from user. Any ideas? Thanks!

• Java/Spring: Why won't Spring use the validator object I have configured?

  - by GMK

  I'm writing a web app with Java & Spring 2.5.6 and using annotations for bean validation. I can get the basic annotation validation working fine, and Spring will even call a custom Validator declared with @Validator on the target bean. But it always instantiates a brand new Validator object to do it. This is bad because the new validator has none of the injected dependencies it needs to run, and so it throws a null pointer exception on validate. I need one of two things and I don't know how to do either. Convince Spring to use the validator I have already configured. Convince Spring to honor the @Autowired annotations when it creates the new validator. The validator has the @Component annotation, like this. @Component public class AccessCodeBeanValidator implements Validator { @Autowired private MessageSource messageSource; Spring finds the validator in the component scan, injects the autowired dependencies, but then ignores it and creates a new one at validation time. The only thing that I can do at the moment is add a validator reference into the controller for each validator object and use that ref directly, instead of relying on the bean validation framework to call the validator for me. It looks like this. // first validate via the annotations on the bean beanValidator.validate(accessCodeBean, result); // then validate using the specific validator class acbValidator.validate(accessCodeBean, result); if (result.hasErrors()) { If anyone knows how to convince spring to use the existing validator, instead of creating a new one, or how to make it do the autowiring when it creates a new one, I'd love to know.

• Extracting images from a PDF

  - by sagar

  My Query I want to extract only images from a PDF document, using Objective-C in an iPhone Application. My Efforts I have gone through the info on this link, which has details regarding different operators on PDF documents. I also studied this document from Apple about PDF parsing with Quartz. I also went through the entire PDF reference document from the Adobe site. According to that document, for each image there are the following operators: q Q BI EI I have created a table to get the image: myTable = CGPDFOperatorTableCreate(); CGPDFOperatorTableSetCallback(myTable, "q", arrayCallback2); CGPDFOperatorTableSetCallback(myTable, "TJ", arrayCallback); CGPDFOperatorTableSetCallback(myTable, "Tj", stringCallback); I use this method to get the image: void arrayCallback2(CGPDFScannerRef inScanner, void *userInfo) { // THIS DOESN'T WORK // CGPDFStreamRef stream; // represents a sequence of bytes // if (CGPDFDictionaryGetStream (d, "BI", &stream)){ // CGPDFDataFormat t=CGPDFDataFormatJPEG2000; // CFDataRef data = CGPDFStreamCopyData (stream, &t); // } } This method is called for the operator "q", but I don't know how to extract an image from it. What should be the solution for extracting the images from the PDF documents? Thanks in advance for your kind help.

• Bind members of different classes

  - by 7vies

  In a C++ program I have two classes (structs) like struct A { int x; double y; // other members }; struct B { int x; double y2; // other members }; I'd like to somehow "bind" the corresponding members, e.g. A::x to B::x and A::y to B::y2. By "bind" I mean ability to obtain a reference to the bound variable, for example given a member of class A I could assign it to the value of the corresponding B member. Once I have such bind, I'd like to build a bind table or something similar which I could iterate over. This would allow, for example, copying the corresponding fields from A a; to B b; like CopyBound(a, b, bind_table);, but probably also doing some other things not limited to Copy interface. The problem with this bind_table is that I want static typing and the bind_table would have to contain different types in this case. For example, a table of pointers to class members would contain &A::x and &A::y, but they are of different type, so I cannot just put them say into an array. Any ideas how this can be conveniently implemented, having as much compile-time type checking as possible?

• Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid

  - by viatropos

  I've been struggling with this for a few days now, haven't pinpointed the problem. I am trying to get OpenID to work in Rails 2.3 and Rails 3, using ruby-openid rack-openid open_id_authentication I am logging in using my viatropos.myopenid.com account, but it consistently returns this error: Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid What could that be from, it's not a very descriptive error... Does it have to do with something ruby-specific, or is this entirely on the OpenID protocol side of things? More specifically, I am using Authlogic and ActiveRecord, so could this be a problem with my User or UserSession models somehow? Or is it more to do with the header or request? In ruby response I'm getting (from puts inside ruby-openid) is: #<OpenID::Consumer::FailureResponse:0x25e282c @reference=nil, @endpoint=#<OpenID::OpenIDServiceEndpoint:0x2601984 @local_id="http://viatropos.myopenid.com/", @display_identifier=nil, @type_uris=["http://specs.openid.net/auth/2.0/signon", "http://openid.net/sreg/1.0", "http://openid.net/extensions/sreg/1.1", "http://schemas.openid.net/pape/policies/2007/06/phishing-resistant", "http://openid.net/srv/ax/1.0"], @used_yadis=true, @server_url="http://www.myopenid.com/server", @canonical_id=nil, @claimed_id="http://viatropos.myopenid.com/">, @message="Server http://www.myopenid.com/server responds that the 'check_authentication' call is not valid", @contact=nil> Any tips would be greatly appreciated.

• How to use 3rd party libraries in glassfish?

  - by Hank

  I need to connect to a MongoDB instance from my EJB3 application, running on glassfish 3.0.1. The Mongo project provides a set of drivers, and I'm able to use them in a standalone Java application. How would I use them in a JEE application? Or maybe better phrasing: how would I make a 3rd party library available to my application when it runs in an EJB container? At the moment, I'm getting a java.lang.NoClassDefFoundError when deploying a bean that tries to import from the library: [#|2010-03-24T11:42:15.164+0100|SEVERE|glassfishv3.0|global|_ThreadID=28;_ThreadName=Thread-1;|Class [ com/mongodb/DBObject ] not found.

• Recommended way to test ActiveRecord associations?

  - by Sugerman

  I have written my basic models and defined their associations as well as the migrations to create the associated tables. I want to be able to test: The associations are configured as intended The table structures support the associations properly I've written FG factories for all of my models in anticipation of having a complete set of test data but I can't grasp how to write a spec to test both belongs_to and has_many associations. For example, given an Organization that has_many Users I want to be able to test that my sample Organization has a reference to my sample User. Organization_Factory.rb: Factory.define :boardofrec, :class => 'Organization' do |o| o.name 'Board of Recreation' o.address '115 Main Street' o.city 'Smallville' o.state 'New Jersey' o.zip '01929' end Factory.define :boardofrec_with_users, :parent => :boardofrec do |o| o.after_create do |org| org.users = [Factory.create(:johnny, :organization => org)] end end User_Factory.rb: Factory.define :johnny, :class => 'User' do |u| u.name 'Johnny B. Badd' u.email '[email protected]' u.password 'password' u.org_admin true u.site_admin false u.association :organization, :factory => :boardofrec end Organization_spec.rb: ... it "should have the user Johnny B. Badd" do boardofrec_with_users = Factory.create(:boardofrec_with_users) boardofrec_with_users.users.should include(Factory.create(:johnny)) end ... This example fails because the Organization.users list and the comparison User :johnny are separate instances of the same Factory. I realize this doesn't follow the BDD ideas behind what these plugins (FG, rspec) seemed to be geared for but seeing as this is my first rails application I'm uncomfortable moving forward without knowing that I've configured my associations and table structures properly.

• Wordpress and Anythingslider Navigation Thumbnails

  - by Tom

  So I am using AnythingSlider in Wordpress. This is why I am trying to call the thumbnails from the original posts. Anything slider will configure thumbnail navigation like this: function formatText(index, panel) { return index + ""; } $(function () { $('.anythingSlider').anythingSlider({ navigationFormatter: formatText // Details at the top of the file on this use (advanced use) }); }); As you can see, the navigationFormatter will allow me to format the nav (including thumbnails) however I want. For example, to format thumbnails, I could do this: navigationFormatter : function(i, panel){ // add thumbnails as navigation links return '<img src="images/th-slide-' + ['civil-1', 'env-1', 'civil-2', 'env-2'][i - 1] + '.jpg">'; } So my issue is getting the wordpress slide images to show up there dynamically, rather than in a folder (as the above example shows). For reference, this is my php query that is pulling the posts image (from a script I've already written: <img class="slider-img" style="float:left;" src="<?php if(function_exists('wp_get_post_image')){ echo wp_get_post_image(array( 'return_html' => false, 'width' => 500 )); } ?>" /> I hope this update helps. Thank you guys so much. The Stack overflow community is great!

• Implementing BindingList<T>

  - by EtherealMonkey

  I am trying to learn more about BindingList because I believe that it will help me with a project that I am working on. Currently, I have an object class (ScannedImage) that is a subtype of a class (HashedImage) that subtypes a native .Net object (Image). There is no reason why I couldn't move the two subtypes together. I am simply subtyping an object that I had previously constructed, but I will now be storing my ScannedImage object in an RDB (well, not technically - only the details and probably the thumbnail). Also, the object class has member types that are my own custom types (Keywords). I am using a custom datagridview to present these objects, but am handling all changes to the ScannedImage object with my own code. As you can probably imagine, I have quite a few events to handle that occur in these base types. So, if I changed my object to implement INotifyPropertyChanged, would the object collection (implementing BindingList) receive notifications of changes to the ScannedImage object? Also, if Keywords were to implement INotifyPropertyChanged, would changes be accessible to the BindingList through the ScannedImage object? Sorry if this seems rather newbish. I only recently discovered the BindingList and not having formal training in C# programming - am having a difficult time moving forward with this. Also, if anyone has any good reference material, I would be thankful for links. Obviously, I have perused the MSDN Library. I have found a few good links on the web, but it seems that a lot of people are now using WPF and ObservableCollection. My project is based on Winforms and .Net3.5 framework. TIA

• Regex: markdown-style link matching

  - by The.Anti.9

  I want to parse markdown style links, but I'm having some trouble matching the reference style ones. Like this one: [id]: http://example.com/ "Optional Title Here" My regex gets the id and the url, but not the title. Heres what I have: /\[([a-zA-Z0-9_-]+)\]: (\S+)\s?("".*?"")?/ I go through and add the references to a hashtable. the id as the key and the value is an instance of a class I made called LinkReference that just contains the url and the title. In case the problem is not my regex, and my code adding the matches to the hash table, Heres my code for that too: Regex rx = new Regex(@"\[([a-zA-Z0-9_-]+)\]: (\S+)\s?("".*?"")?"); MatchCollection matches = rx.Matches(InputText); foreach (Match match in matches) { GroupCollection groups = match.Groups; string title = null; try { title = groups[3].Value; } catch (Exception) { // keep title null } LinkReferences.Add(groups[1].Value, new LinkReference(groups[2].Value, title)); }

• Java equivalent to VS solution file

  - by Chris

  I'm a C# guy trying to learn Java. I understand the syntax and the basic architecture of the Java platform, and have no problem doing smaller projects myself, but I'd really like to be able to download some open source projects to learn from the work of others. However, I'm running into a stumbling block that I can't seem to find any information on. When I download an open source .NET project, I can open the .sln file with visual studio and everything just loads. Sure, there's occasionally a missing reference or something, but there's really very little configuration required to get things going. I'm not sensing the same ease of use with Java. I'm using eclipse at the moment, and it feels like for every project I have to create a brand new Eclipse project using "create from existing source", and almost nothing compiles properly without significant reconfiguration. In the case of web projects, it's even worse, because Eclipse doesn't appear to support creating a web project from existing source. I have to create a standard Java project from source, then then apparently modify the project file to include the bindings for the web toolkit stuff to work properly. Assuming I want to be able to contribute to a project later on, I shouldn't have to be making such drastic changes to the file structure to get my IDE to a workable state. What am I missing?

• How do I correctly install dulwich to get hg-git working on Windows?

  - by Joshua Flanagan

  I'm trying to use the hg-git Mercurial extension on Windows (Windows 7 64-bit, to be specific). I have Mercurial and Git installed. I have Python 2.5 (32-bit) installed. I followed the instructions on http://hg-git.github.com/ to install the extension. The initial easy_install failed because it was unable to compile dulwich without Visual Studio 2003. I installed dulwich manually by: git clone git://git.samba.org/jelmer/dulwich.git cd dulwich c:\Python25\python setup.py --pure install Now when I run easy_install hg-git, it succeeds (since the dulwich dependency is satisfied). In my C:\Users\username\Mercurial.ini, I have: [extensions] hgext.bookmarks = hggit = When I type 'hg' at a command prompt, I see: "* failed to import extension hggit: No module named hggit" Looking under my c:\Python25 folder, the only reference to hggit I see is Lib\site-packages\hg_git-0.2.1-py2.5.egg. Is this supposed to be extracted somewhere, or should it work as-is? Since that failed, I attempted the "more involved" instructions from the hg-git page that suggested cloning git://github.com/schacon/hg-git.git and referencing the path in my Mercurial configuration. I cloned the repo, and changed my extensions file to look like: [extensions] hgext.bookmarks = hggit = c:\code\hg-git\hggit Now when I run hg, I see: * failed to import extension hggit from c:\code\hg-git\hggit: No module named dulwich.errors. Ok, so that tells me that it is finding hggit now, because I can see in hg-git\hggit\git_handler.py that it calls from dulwich.errors import HangupException That makes me think dulwich is not installed correctly, or not in the path. Update: From Python command line: import dulwich yields Import Error: No module named dulwich However, under C:\Python25\Lib\site-packages, I do have a dulwich-0.5.0-py2.5.egg folder which appears to be populated. This was created by the steps mentioned above. Is there an additional step I need to take to make it part of the Python "path"?

• Basic site analytics doesn't tally with Google data

  - by Jenkz

  After being stumped by an earlier quesiton: SO google-analytics-domain-data-without-filtering I've been experimenting with a very basic analytics system of my own. MySQL table: hit_id, subsite_id, timestamp, ip, url The subsite_id let's me drill down to a folder (as explained in the previous question). I can now get the following metrics: Page Views - Grouped by subsite_id and date Unique Page Views - Grouped by subsite_id, date, url, IP (not nesecarily how Google does it!) The usual "most visited page", "likely time to visit" etc etc. I've now compared my data to that in Google Analytics and found that Google has lower values each metric. Ie, my own setup is counting more hits than Google. So I've started discounting IP's from various web crawlers, Google, Yahoo & Dotbot so far. Short Questions: Is it worth me collating a list of all major crawlers to discount, is any list likely to change regularly? Are there any other obvious filters that Google will be applying to GA data? What other data would you collect that might be of use further down the line? What variables does Google use to work out entrance search keywords to a site? The data is only going to used internally for our own "subsite ranking system", but I would like to show my users some basic data (page views, most popular pages etc) for their reference.
