  • Sunspot_Rails Rake Aborted When Running Reindex

    - by Walter Chen
    I'm getting the following output after running rake sunspot:reindex. I'm a novice at Rails. I want to add sunspot_rails to my project to add search functionality (with the hope of deploying the project with Heroku). I'm using Rails 3. I followed the instructions here: https://github.com/outoftime/sunspot/blob/master/sunspot_rails/README.rdoc. My various other attempts to diagnose the problem included: installing sunspot in addition to sunspot_rails. I ended up with sunspot_rails v. 1.2.0 and 1.2.1 so I uninstalled 1.2.1 because I have sunspot_rails 1.2.0. installed the nokogiri gem which I understand is a dependency for sunspot_rails. installed libxml2 separately following the instructions here to install nokogiri: http://www.engineyard.com/blog/2010/getting-started-with-nokogiri/ ** Invoke sunspot:reindex (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute sunspot:reindex rake aborted! undefined local variable or method counter' for [removed pound]<Class:0x10359aef8> /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:1008:inmethod_missing' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:235:in solr_index' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/relation/batches.rb:71:infind_in_batches' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:440:in __send__' /Library/Ruby/Gems/1.8/gems/activerecord-3.0.3/lib/active_record/base.rb:440:infind_in_batches' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:234:in solr_index' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/searchable.rb:184:insolr_reindex' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:57 /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:56:in each' /Library/Ruby/Gems/1.8/gems/sunspot_rails-1.2.0/lib/sunspot/rails/tasks.rb:56 /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:incall' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:in execute' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:ineach' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:in execute' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:597:ininvoke_with_call_chain' /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/monitor.rb:242:in synchronize' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:ininvoke_with_call_chain' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:583:in invoke' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2051:ininvoke_task' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:ineach' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:instandard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2023:in top_level' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2001:inrun' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in standard_exception_handling' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/lib/rake.rb:1998:inrun' /Library/Ruby/Gems/1.8/gems/rake-0.8.7/bin/rake:31 /usr/bin/rake:19:in `load' /usr/bin/rake:19 This is what I have in class I'd like to search: searchable do text :fname text :mname text :lname, :default_boost => 2 end Any help would be greatly appreciated!

  • HIB Games (Aquaria & Penumbra) cannot find libGL.so.1 even though it exists

    - by aberration
    I'm try to play some Humble Indie Bundle (HIB) games, but I'm getting errors with Aquaria and Penumbra: Overture that are related to the libGL.so.1 file. Aquaria gives this error on launch: Message: SDL_GL_LoadLibrary Error: Failed loading libGL.so.1 And Penumbra: Overture gives this error on launch: ./penumbra.bin: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory I know that the file libGL.so.1 does exist (in /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1). From past errors like this, I'm guessing that you need to symlink the library to another directory, but I can't figure out which one.

  • Debian package libmarkdown-php, how can I use it? [closed]

    - by JamesM-SiteGen
    Hello all, I am just wondering how do you implement libmarkdown-php in a php script? By this, I mean: What code do I run to use the markdown library? Does it simply just add one function? Does it allows me to encode markdown2html and vise versa? Where is a doc for this package, I can't find one? :( Okay, so it terns out that I found the docs, just did not match them up, the project-page did not contain any info on it being the Squeeze package libmarkdown-php, Said to know it is not in Lenny. Thanks @palhmbus for matching them. :)

  • Rendering citations and references in HTML using PHP/Perl/Python/

    - by Nick
    Is there a PHP/Perl/Python/... library for picking citations out of an HTML file and rendering a nice list of references at the bottom, like in Wikipedia? I'm developing a website with heavily-sourced content, and I'd really like to have automatically-generated lists of formatted references, like in Wikipedia. (Check out their philosophy page, and see how the superscript numbered citations interact with the references at the bottom. This is all dynamically generated, automatically ordered & linked.) They do it really well: the citations are linked to the references (which are backlinked to the citations), when you click on one of the links, the target is highlighted, etc. I'm tempted to build the site on MediaWiki just for this one feature, but it seems like overkill. Do I have any options?

  • About Data Objects and DAO Design when using Hibernate

    - by X. Ma
    I'm hesitating between two designs of a database project using Hibernate. Design #1. (1) Create a general data provider interface, including a set of DAO interfaces and general data container classes. It hides the underneath implementation. A data provider implementation could access data in database, or an XML file, or a service, or something else. The user of a data provider does not to know about it. (2) Create a database library with Hibernate. This library implements the data provider interface in (1). The bad thing about Design #1 is that in order to hide the implementation details, I need to create two sets of data container classes. One in the general data provider interface - let's call them DPI-Objects, the other set is used in the database library, exclusively for entity/attribute mapping in Hibernate - let's call them H-Objects. In the DAO implementation, I need to read data from database to create H-Objects (via Hibernate) and then convert H-Objects into DPI-Objects. Design #2. Do not create a general data provider interface. Expose H-Objects directly to components that use the database lib. So the user of the database library needs to be aware of Hibernate. I like design #1 more, but I don't want to create two sets of data container classes. Is that the right way to hide H-Objects and other Hibernate implementation details from the user who uses the database-based data provider? Are there any drawbacks of Design #2? I will not implement other data provider in the new future, so should I just forget about the data provider interface and use Design #2? What do you think about this? Thanks for your time!

  • WpfToolkit DataGrid does not work in Windows Phone 7

    - by Igor Zevaka
    I am trying to use WpfToolkit DataGrid in Windows Phone 7 project (Silverligt 4) and it's not working. Here is the XAML: <UserControl x:Class="SilverlightControls.Grid" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" xmlns:wtk="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" d:DesignHeight="480" d:DesignWidth="480"> <Grid x:Name="LayoutRoot" Background="#FF1F1F1F" Width="960"> <Grid x:Name="TitleGrid"> <TextBlock Text="{Binding Title}" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid> <wtk:DataGrid> </wtk:DataGrid> </Grid> </UserControl> The project compiles fine but crashes at runtime trying to load this control. The best clue I got so far is from Visual Studio Designer. Once I add wtk:DataGrid to the control the visual designer does not load and below is the exception it displays. Could it be that WpfToolkit relies on PresentationFramework.dll and it's not available in SL4?

  • Do I need to use any other attributes other than CssClassProperty to enabled design-time support?

    - by keith
    Hi, I'm trying to provide the same design-time support that the CssClass provides on some custom properties of a server control. The documentation suggests that decorating the property with the CssClassProperty is all that's required. [CssClassProperty] public string SomeOtherCssClass{get;set;} This has no effect, in vs2008 or vs2010. I've looked at the WebControl class using reflector and implemented all the attributes, and every combination thereof, to my property and still no class dropdown. Some blog posts suggest that the use of the Editor attribute but a) there's not mention of it in the documentation and b) none of editors which are remotely related to css classes have any effect either. Am I missing something to enable this feature? Thanks in advance, Keith.

  • Python Image Library: How to combine 4 images into a 2 x 2 grid?

    - by Casey
    I have 4 directories with images for an animation. I would like to take the set of images and generate a single image with the 4 images arranged into a 2x2 grid for each frame of the animation.

  • Does anyone know of a library in Java that can parse ESRI Shapefiles?

    - by KingNestor
    I'm interested in writing a visualization program for the road data in the 2009 Tiger/Line Shapefiles. I'd like to draw the line data to display all the roads for my county. The ESRI Shapefile or simply a shapefile is a popular geospatial vector data format for geographic information systems software. It is developed and regulated by ESRI as a (mostly) open specification for data interoperability among ESRI and other software products.1 A "shapefile" commonly refers to a collection of files with ".shp", ".shx", ".dbf", and other extensions on a common prefix name (e.g., "lakes.*"). The actual shapefile relates specifically to files with the ".shp" extension, however this file alone is incomplete for distribution, as the other supporting files are required. Does anyone know of existing libraries for parsing and reading in the line data for Shapefiles?

  • is it wasteful/bad design to use a vector/list where in most instances it will only have one element

  • Compiling external C++ library (Octave) for iPhone (Fortran compiler missing?)

    - by Shaggy Frog
    A friend of mine asked me if it would be possible to port the Octave project to the iPhone. I haven't compiled an external package for an iPhone project before, so I downloaded the source code, and then used some scripts found on a couple of different Web sites (one, two) to try and build the libraries. However, when I try either of these scripts (which are nearly identical), they eventually die during the configure phase with the following error output: [...snip checks...] checking whether we are using the GNU Fortran 77 compiler... no checking whether accepts -g... no checking how to get verbose linking output from ... configure: WARNING: compilation failed checking for Fortran 77 libraries of ... rm: conftest.dSYM: is a directory checking for dummy main to link with Fortran 77 libraries... rm: conftest.dSYM: is a directory none checking for Fortran 77 name-mangling scheme... configure: error: cannot compile a simple Fortran program See `config.log' for more details. Is the problem that the iPhone SDK/Xcode doesn't include a Fortran cross-compiler, or am I doing something wrong?

  • can we have one attribute with multiple values in an eav design?

    - by Shekhar
    i am doing a database design using EAV. I am facing an issue when i try to model an entity with attribute having multiple values? For example Entity id | name | description 1 | configuration1 | configuration1 Attribute id | entityId | name | type 1 | 1 |att1 | string 2 | 1 |att2 | int 3 |1 | att3 | List (How will i model this?) Value id | attributeId | value 1 | 1 | a 2 | 2 | 1 3 | 3 | b 4 | 3 | c 5 | 3 |d Is this the correct way to handle list of values? Please provide any helpful link to model this? Thanks Shekhar

  • Haskell Linear Algebra Matrix Library for Arbitrary Element Types

    - by Johannes Weiß
    I'm looking for a Haskell linear algebra library that has the following features: Matrix multiplication Matrix addition Matrix transposition Rank calculation Matrix inversion is a plus and has the following properties: arbitrary element (scalar) types (in particular element types that are not Storable instances). My elements are an instance of Num, additionally the multiplicative inverse can be calculated. The elements mathematically form a finite field (??2256). That should be enough to implement the features mentioned above. arbitrary matrix sizes (I'll probably need something like 100x100, but the matrix sizes will depend on the user's input so it should not be limited by anything else but the memory or the computational power available) as fast as possible, but I'm aware that a library for arbitrary elements will probably not perform like a C/Fortran library that does the work (interfaced via FFI) because of the indirection of arbitrary (non Int, Double or similar) types. At least one pointer gets dereferenced when an element is touched (written in Haskell, this is not a real requirement for me, but since my elements are no Storable instances the library has to be written in Haskell) I already tried very hard and evaluated everything that looked promising (most of the libraries on Hackage directly state that they wont work for me). In particular I wrote test code using: hmatrix, assumes Storable elements Vec, but the documentation states: Low Dimension : Although the dimensionality is limited only by what GHC will handle, the library is meant for 2,3 and 4 dimensions. For general linear algebra, check out the excellent hmatrix library and blas bindings I looked into the code and the documentation of many more libraries but nothing seems to suit my needs :-(. Update Since there seems to be nothing, I started a project on GitHub which aims to develop such a library. The current state is very minimalistic, not optimized for speed at all and only the most basic functions have tests and therefore should work. But should you be interested in using or helping out developing it: Contact me (you'll find my mail address on my web site) or send pull requests.

  • Singleton class design in C#, are these two classes equivalent?

    - by Oskar
    I was reading up on singleton class design in C# on this great resource and decided to go with alternative 4: public sealed class Singleton1 { static readonly Singleton1 _instance = new Singleton1(); static Singleton1() { } Singleton1() { } public static Singleton1 Instance { get { return _instance; } } } Now I wonder if this can be rewritten using auto properties like this? public sealed class Singleton2 { static Singleton2() { Instance = new Singleton2(); } Singleton2() { } public static Singleton2 Instance { get; private set; } } If its only a matter of readability I definitely prefer the second version, but I want to get it right.

  • Java: Use jar library's from package manager in Linux.

    - by jonescb
    I'm trying to find the best way to use Java libraries that were installed by the package manager instead of just putting a copy into ${project.root}/lib My distro, Gentoo, has a package for Java libraries like jdbc-postgresql. It's installed to /usr/share/jdbc-postgresql/lib/jdbc-postgresql.jar I assume that this path may be different in Ubuntu, Fedora, or Arch. Is there any way to do like what C does? Where you just add a -lfoo, and the linker would find libfoo.so. I'm using Ant 1.8.0 and Java 1.6.0_19.

  • Getting 'error while loading shared libraries' when using -L to specifically find the library.

    - by e5
    I've been trying to solve this for a few hours now. I am compiling some c files using gcc. The files require libpbc, so I am using the -L flag to point gcc at the directory which contains libpbc.so.1. The code compiles without error yet when I attempt to run it I get the following error message: ./example.out: error while loading shared libraries: libpbc.so.1: cannot open shared object file: No such file or directory Looking at similar questions this error message seems to indicate that gcc can't find libpbc.so.1. I know gcc sees libpbc.so.1 because when I rename libpbc.so.1 to something else it fails to compile. I am using -L to point to the directory which contains libpbc.so.1. Not sure what next steps I can take to figure this out. Would appreciate any ideas. What does this error message mean exactly?

  • How can I avoid properties being reset at design-time in tightly bound user controls?

    - by David Anderson
    I have UserControl 'A' with a label, and this property: /// <summary> /// Gets or Sets the text of the control /// </summary> [ Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Category("Appearance") ] public override string Text { get { return uxLabel.Text; } set { uxLabel.Text = value; } } I then have UserControl 'B' which has UserControl 'A' on it, and I set the Text Property to "My Example Label" in the designer. Then, I have my MainForm, which has UserControl 'B' on it. Each time I do a build or run, the Text property of UserControl 'A' is reset to its default value. I suppose this is because since I am doing a rebuild, it rebuilds both UserControl 'A' and 'B', thus causing the problem. How can I go about a better approach to design pattern to avoid this type of behavior when working with tightly bound controls and forms in a application?

  • Static library woes in iPhone 3.x with categories and C libraries

    - by hgpc
    I have a static library (let's call it S) that uses a category (NSData+Base64 from MGTwitterEngine) and a C library (MiniZip wrapped by ZipArchive). This static library is used in an iPhone 3.x project (let's call it A). To be able to use the MiniZip library I included its files in project A as well as the static library S. If not I get compilation errors. Project A works fine on the simulator. When I run it on the device, I get unrecognized selector errors when the category is used. As pointed out here, it seems there's a linker bug that affects categories in iPhone 3.x (http://stackoverflow.com/questions/1147676/categories-in-static-library-for-iphone-device-3-0). The workaround is to add -all_load to the Other Linker Flags of the project that references the static library. However, if I do this then I get duplicate symbol errors because I included the MiniZip libraries in project A. A workaround is to include the category files in project A as well. If I do this, project A works well in the device, but fails to build on the simulator because of duplicate symbol errors. How should I set up project A to make it work on the simulator and the device with the same configuration?
