  • Posting Documentation onto a Joomla Site

    - by Chris Spicer
    I would like to create some documentation and post it onto my Joomla website. This documentation would be something along the lines of the MSDN documentation: i.e. each page would follow a basic template. Intuitively I feel I have two ways of achieving this: 1) Creating each page of documentation as a separate article, and then linking them up. 2) Creating some kind of template and filling the information from a database. The second option being preferable in the long run. Unforunately I have no idea how to achieve what I'm looking for. I hoped that there would be a component out there that woud help me, but Googling for 'Joomla Documentation' just brings up the documentation for Joomla itself. Has anyone out there put documentation on their site, and how did they achieve it?

  • NLP Library in java

    - by user337962
    hi, I need a simple Natural Language Processing library written in java which can be used to process a search query/question. What I want actually is to separate the main subject which is being searched in a query. For an example, considering a query like "What is an apple?", it's perfect if the main search word apple can be extracted. This is for a semantic search engine development purpose. Can anyone please suggest a suitable nlp library for this?? Thank You!!

  • Creating a ListView using Category (Control Panel-Like) View

    - by Andrew Moore
    I currently have an application which uses a regular ListView with groups to show a bunch of modules. I would like to use a Category view. Category view is the new view introduced in Windows Vista for the Control Panel: Is there a third party control or a way (via API) to create a ListView which mimics the behavior of the Windows 7 Control Panel? Categories with icons and action links. Separate events for Category Click and Action Click. One or two column layout Separators between action links or lines

  • What data is actually stored in a B-tree database in CouchDB?

    - by Andrey Vlasovskikh
    I'm wondering what is actually stored in a CouchDB database B-tree? The CouchDB: The Definitive Guide tells that a database B-tree is used for append-only operations and that a database is stored in a single B-tree (besides per-view B-trees). So I guess the data items that are appended to the database file are revisions of documents, not the whole documents: +---------|### ... | | +------|###|------+ ... ---+ | | | | +------+ +------+ +------+ +------+ | doc1 | | doc2 | | doc1 | ... | doc1 | | rev1 | | rev1 | | rev2 | | rev7 | +------+ +------+ +------+ +------+ Is it true? If it is true, then how the current revision of a document is determined based on such a B-tree? Doesn't it mean, that CouchDB needs a separate "view" database for indexing current revisions of documents to preserve O(log n) access? Wouldn't it lead to race conditions while building such an index? (as far as I know, CouchDB uses no write locks).

  • Shared library to minimise size of FLA file

    - by Dmitry
    In a project we use large flash FLA file with lots of graphic assets, but the actual data that is changed is just in a few symbols. Sometimes it is not very efficient to transfer the whole FLA file that comes up to 20MB now. I was thinking about using Shared Libraries, but it seems that, even if you import external library, it still copies the whole assets into the destination file, but does not link it from external file. Consequently, size of the FLA file still remains the same. Is there any way to split FLA files into few separate in order to minimise size of the most frequently updated file and keep all unchanged data in another file?

  • How To Use ObjectDataSource With Complex Objects and FormView Control

    - by obautista
    I have a complex object. For example a SCHOOL object that contains a collection of PERSON object. How can I use the ObjectDataSource control with a FormView and flatten the complex object? An example display would be to display the school name and comma separate the students on the page. Is this possible? I.E. public string Id { get { return m_id; } set { m_id = value; } } public string SchoolName { get { return m_schoolName; } set { m_schoolName = value; } } public List(Person Students { get { return m_students; } set { m_cast = students; } }

  • Should class IOException in Java have been an unchecked RuntimeException?

    - by Derek Mahar
    Do you agree that the designers of Java class java.io.IOException should have made it an unchecked run-time exception derived from java.lang.RuntimeException instead of a checked exception derived only from java.lang.Exception? I think that class IOException should have been an unchecked exception because there is little that an application can do to resolve problems like file system errors. However, in When You Can't Throw An Exception, Elliotte Rusty Harold claims that most I/O errors are transient and so you can retry an I/O operation several times before giving up: For instance, an IOComparator might not take an I/O error lying down, but — because many I/O problems are transient — you can retry a few times, as shown in Listing 7: Is this generally the case? Can a Java application correct I/O errors or wait for the system to recover? If so, then it is reasonable for IOException to be checked, but if it is not the case, then IOException should be unchecked so that business logic can delegate handling of this exception to a separate system error handler.

  • iPhone: One Object, One Thread

    - by GingerBreadMane
    On the iPhone, I would like to do some operations on an image in a separate thread. Rather than dealing with semiphores, locking, etc., I'd like to use the 'One Object, One Thread' method of safely writing this concurrent operation. I'm not sure what is the correct way to copy my object into a new thread so that the object is not accessed in the main thread. Do I use the 'copy' method? If so, do I do this before the thread or inside the thread? ... -(void)someMethod{ UIImage *myImage; [NSThread detachNewThreadSelector:@selector(getRotatedImage:) toTarget:self withObject:myImage]; } -(void)getRotatedImage:(UIImage *)image{ ... ... UIImage *copiedImage = [image copy]; ... ... }

  • White Label Ecommerce app. Shared or Individual dbs

    - by MetaDan
    Currently I'm working with an in house white label cms that we resell to multiple clients and it all runs from the same box/db. I'm just looking at converting this to have an ecommerce version that we'll run alongside it. I'm wondering whether there will be an issue keeping all the products/categories/orders in one db or whether it would be advisory to separate each instance of the site into its own db for this. These white label instances will only be sold to smaller companies that probably wont have masses of traffic/products and are looking for a simple ecommerce site. Anything larger will definitely get its own hosting and db. But for smaller scale stuff do you think a single db will be ok?

  • best approach to do jsf form validation

    - by gurupriyan.e
    If I have many input controls in a form (There are separate validators for each of these input controls - like required,length and so on ) , there is a command button which submits the form and calls an action method. The requirement is - though the input control values are , say , individually okay - the combination of these values should be okay to process them together after the form submission - Where do i place the code to validate them together? 1) Can i add a custom validator for the command button and validate the combination together? like validate(FacesContext arg0, UIComponent arg1, Object value) but even then I will not have values of the other input controls except for the command button's/component's value right ? 2) can i do the validation of the combination in the action method and add validation messages using FacesMessage ? or do you suggest any other approach? Thanks for your time.

  • Indexes and multi column primary keys

    - by David Jenings
    Went searching and didn't find the answer to this specific noob question. My apologies if I missed it. In a MySQL database I have a table with the following primary key PRIMARY KEY id (invoice, item) In my application I will also frequently be selecting on "item" by itself and less frequently on only "invoice". I'm assuming I would benefit from indexes on these columns. MySQL does not complain when I define the following: INDEX (invoice), INDEX (item), PRIMARY KEY id (invoice, item) But I don't see any evidence (using DESCRIBE -- the only way I know how to look) that separate indexes have been established for these two columns. So the question is, are the columns that make up a primary key automatically indexed individually? Also, is there a better way than DESCRIBE to explore the structure of my table?

  • Ref to map vs. map to refs vs. multiple refs

    - by mikera
    I'm working on a GUI application in Swing+Clojure that requires various mutable pieces of data (e.g. scroll position, user data, filename, selected tool options etc.). I can see at least three different ways of handling this set of data: Create a ref to a map of all the data: (def data (ref { :filename "filename.xml" :scroll [0 0] })) Create a map of refs to the individual data elements: (def datamap { :filename (ref "filename.xml") :scroll (ref [0 0]) })) Create a separate ref for each in the namespace: (def scroll (ref [0 0])) (def filename (ref "filename.xml")) Note: This data will be accessed concurrently, e.g. by background processing threads or the Swing event handling thread. However there probably isn't a need for consistent transactional updates of multiple elements. What would be your recommended approach and why?

  • MVC - Same URL, multiple views

    - by Amati
    Hi, Is it considered bad practice to have multiple views for same URL in MVC, based on different user roles? For example: http://www.domain.com/ViewProductID/123 will show a "normal" product page for a regular user and it will show an "enhanced" (product stats, ability to edit title etc..) version to someone logged in as admin. If it's bad practice, why? If it's ok, what's the best way to implement it? 2 separate templates or 1 template scattered with if..else? Thanks!

  • Have threads run indefinitely in a java application

    - by TP
    I am trying to program a game in which I have a Table class and each person sitting at the table is a separate thread. The game involves the people passing tokens around and then stopping when the party chime sounds. how do i program the run() method so that once I start the person threads, they do not die and are alive until the end of the game One solution that I tried was having a while (true) {} loop in the run() method but that increases my CPU utilization to around 60-70 percent. Is there a better method?

  • Visual Studio - how to create two projects using the same sources

    - by mack369
    My solution consists of 2 executable projects and a couple dlls. Project1 is a Smart Device Project, Project2 is a Windows Forms Project. Both projects use the same libraries, the reason of that is I want to test my libraries on PC before I deploy it on the device. The problem is that the DLL project type can be Smart Device Class Library or Class Library, not both. I cannot add a reference from SD project to WF and vice versa. I was able to add reference from SD project to a dll file (generated from Class Library project) instead of the project itself, but for some reason I got the message "cannot load XXX type from YYY assembly". It doesn't depend on my code, because when I created separate project for the same sources, everything was fine. The only solution I've found is to create 2 types of projects for each library, but I don't know how to make 2 projects based on the same sources.

  • Two CVS projects into one SVN project

    - by komunca
    I have two CVS projects, which I maintain in Eclipse. I check out first project, and for second project I use "checkout in existing project" option, so I'm able to maintain two CVS projects into one Eclipse project. Doing this I'm able to Tag both projects with the same tag,etc. And know, time has come to start using SVN. I was able to create two separate CVS dump files, and when I used svnadmin to load then into SVN repository, I wasn't able to keep the structure I had in CVS! So, when i import both dump seperatly into SVN I get the following structure: ProjA - brancher tags trunk ProjB bracnches tags trunk In CVS I was able to have ProjB as a child folder of the ProjA trunk! Is there any way to implement this using SVN?

  • How to customise the TextView inside a Spinner?

    - by Janusz
    I have a Spinner with an ArrayAdapter that feeds Values into it. The Problem is that the text is to long for the view and the result is a very very ugly spinner. As can be seen in the screenshot: I tried to pass the Id of my own TextView into the Adapter but everytime the spinner should be shown I get an Exception that the Id I supplied is not valid: 04-26 17:38:39.695: ERROR/AndroidRuntime(4276): android.content.res.Resources$NotFoundException: Resource ID #0x7f09003a type #0x12 is not valid Where do I have to define the TextView? In a separate xml file? With a surrounding viewgroup? It would help me a lot if I could see an example of the adapter initialization and the textview definition?

  • Localizing other pages in Settings.bundle

    - by joneswah
    I have other pages within my app preferences which are stored as separate files within the settings.bundle. It has come time to localize my app and I can only seem to get the Root values to localize. I was wondering whether there was a trick? The following image shows that my second screen is stored within a file called "MyPrefs.plist" and I have created a corresponding named file "MyPrefs.strings" in the en.lproj directory. Mirroring the same naming and location as the Root.plist and Root.strings. The values with the Root.plist are converted as expected but not in the extra screen. Is there any trick to localizing secondary screens with the settings.bundle?

  • Rolling back or re-creating the master branch in git?

    - by Matthew Savage
    I have a git repo which has a few branches - there's the master branch, which is our stable working version, and then there is a development/staging branch which we're doing new work in. Unfortunately it would appear that without thinking I was a bit overzealous with rebasing and have pulled all of the staging code into Master over a period of time (about 80 commits... yes, I know, stupid, clumsy, poor code-man-ship etc....). Due to this it makes it very hard for me to do minor fixes on the current version of our app (a rails application) and push out the changes without also pushing out the 'staged' new features which we don't yet want to release. I am wondering if it is possible to do the following: Determine the last 'trunk' commit Take all commits from that point onward and move them into a separate branch, more or less rolling back the changes Start using the branches like they were made for. Unfortunately, though, I'm still continually learning about git, so I'm a bit confused about what to really do here. Thanks!

  • What are real-world examples of Gradle's dependency graph?

    - by Michael Easter
    As noted in the documentation, Gradle uses a directed acyclic graph (DAG) to build a dependency graph. From my understanding, having separate cycles for evaluation and execution is a major feature for a build tool. e.g. The Gradle doc states that this enables some features that would otherwise be impossible. I'm interested in real-world examples that illustrate the power of this feature. What are some use-cases for which a dependency graph is important? I'm especially interested in personal stories from the field, whether with Gradle or a similarly equipped tool. I am making this 'community wiki' from the outset, as it will be difficult to assess a 'correct' answer.

  • Trouble rendering a view inside a generic class

    - by Horace Loeb
    I'm trying to encapsulate the logic for generating my sitemap in a separate class so I can use Delayed::Job to generate it out of band: class ViewCacher include ActionController::UrlWriter def initialize @av = ActionView::Base.new(Rails::Configuration.new.view_path) @av.class_eval do include ApplicationHelper end end def cache_sitemap songs = Song.all sitemap = @av.render 'sitemap/sitemap', :songs => songs Rails.cache.write('sitemap', sitemap) end end But whenever I try ViewCacher.new.cache_sitemap I get this error: ActionView::TemplateError: ActionView::TemplateError (You have a nil object when you didn't expect it! The error occurred while evaluating nil.url_for) on line #5 of app/views/sitemap/_sitemap.builder: I assume this means that ActionController::UrlWriter is not included in the right place, but I really don't know

  • Can you suggest good ways of generating URLS for viewing tagged content

    - by rikh
    For example, here on stack overflow the URL http://stackoverflow.com/questions/tagged/javascript+php will give you all questions tagged with javascript and php. The system I have allows tags with spaces in them, so the approach used here would not be a good fit for me. What character would you use to separate the tags, so the URLs are still human readable, google readable and web browser compatible. My gut feeling was to use commas. eg http://example.com/tagged/first+tag,second+tag Any feedback or suggestions would be welcome.

  • How to Use Eclipse to Debug JNI code (Java & C/C++)

    - by tkryger
    While I can debug my application with the Eclipse JDT debugger for Java code and GDB for C code, I would prefer to use a single tool for all my debugging. I found several projects that enable "mixed-mode" debugging in Eclipse and include support for single stepping between Java and native code. Intel's Integrated Debugger for Java/JNI Environments Mariot Chauvin's Summer of Code Project: Support Seamless Debugging between JDT & CDT Unfortunately, one claims to be pre-release quality and the other is currently unmaintained. Are there any plug-ins that bring mixed mode debugging functionality to Eclipse in a reliable way or should I continue to use two separate debuggers?

  • Getting my webapp to be database agnostic with Hibernate...

    - by JellyHead
    So the ultimate in scope-creep came in the other day: since we're using Hibernate, could we make our webapp run on Oracle as well as MySQL, interchangably? I thought this would be a simple case of changing hibernate.cfg.xml so that instead of explicity stating MySQL-specific options, it would reference a JNDI datasource, allowing the application to build regardless of the database we intend to deploy to. Then changing to a different database would simply mean changing the separate datasource configuration in JBoss, Jetty, WebLogic etc. Is this realistic? Well, I got as far as setting that up in Jetty, but What's tripping me up right now is error about the hibernate.dialect not having been set in hibernate.cfg.xml. But If I set the dialect there, then my app is still going to be built in either MySQL or Oracle flavours, which is not really what I want. Either I'm trying to attempt the impossible or I've missed something fundamentally obvious... anyone else had a similar problem (and subsequent solution/workaround)?
