• How do I start IRB console from a rake task?

  - by Michael Lang

  I'm trying to write a rake task that will set up an environment mirroring my project. task :environment do require 'rubygems' require 'sequel' # require 'my_projects_special_files' end task :foo => [:environment] do require 'irb' IRB.start end Leads to irb complaining that "foo" doesn't exist (the name of the task) 10:28:01:irb_test rake foo --trace (in /Users/mwlang/projects/personal/rake/irb_test) ** Invoke foo (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute foo rake aborted!

• Is gwt-graphics 0.9.3 compatible with gwt 2.0.3

  - by sprasad12

  Hi, I am using gwt graphics(vaadin) for one of my project, till yesterday i had gwt1.7.1 and all the drawing objects were working fine. For some reason i had to install eclipse again and so now i have gwt 2.0.3. I am observing few problems with graphics now, like the text is not getting positioned properly, if i do any changes to the code, concerned to drawing objects, it is not showing up. Therefore wanted to know whether gwt-graphics0.9.3 was compatible with gwt 2.0. Thank you.

• Creating a future proof .NET 3.5 SP1 installer prerequisite for setup.exe AND the .MSI

  - by Ruben Bartelink

  I've demanded .NET 3.5 SP1 a la http://stackoverflow.com/questions/88136/will-a-vs2008-setup-project-update-net-3-5-sp1. This makes the setup.exe check correctly. I've also added a "SP1" launch condition to my MSI so it doesn't let the user install my .NET 3.5SP1 app via launching the MSI (and replaced the [VSDNETMSG] in the Framework condition message with one that actually mentions SP1). From a future proofing point of view, this feels wrong. I want the condition to be: (NETVer=3.5 AND Net35SPLevel=1) OR (NETVer=>3.5) not (NETVer=3.5 AND Net35SPLevel=1) Is there any way to do that? The framework check doesnt have a condition property to allow me to add a sub-condition... Yes, I could also just not worry my pretty little head about it :P If one of the MS versioning experts out there reads this, if you're going to put stuff that code depends on into SPs, can you please make the installer be able to check for it OOTB. (I really wish they had come up with a better numbering scheme - the world and its dog could see that this was going to get confusing)

• Implementing Domain Driven Design

  - by Steve Dunn

  Is anyone using the techniques from Domain Driven Design? I've recently read the Eric Evans book of the same name (well, most of it!) and would be interested to hear from anyone who's implemented all/some of it in a project (particularly in C#/C++) I've kept this question open ended as I'd like to see as many comments as possible, but I have a few questions in particular: 1 - Should value types be real 'value types' if the language supports it? e.g. a struct in C# 2- Is there any feature in C# that makes clearer the association between the language and the model (for instance, this is an entity, this is an aggregate etc.)

• How can I enable Pascal casing by default when using Jackson JSON in Spring MVC?

  - by bhilstrom

  I have a project that uses Spring MVC to create and handle multiple REST endpoints. I'm currently working on using Jackson to automatically handle the seralization/deserialization of JSON using the @RequestBody and @ResponseBody annotations. I have gotten Jackson working, so I've got a starting point. My problem is that our old serialization was done manually and used Pascal casing instead of Camel casing ("MyVariable" instead of "myVariable"), and Jackson does Camel casing by default. I know that I can manually change the name for a variable using @JsonProperty. That being said, I do not consider adding "@JsonProperty" to all of my variables to be a viable long-term solution. Is there a way to make Jackson use Pascal casing when serializing and deserializing other than using the @JsonProperty annotation?

• Problems Executing iPhone "GenericKeychain" Example

  - by AO

  I can't get apple's "GenericKeychain" example to run. I have replaced all 5 occurrences, as mentioned in the readme file, of "YOUR_APP_ID_HERE.com.yourcompany" with my own string: se.[company name].[project name].demo. The compilation goes fine but when trying to run it on the phone, an error saying "The executable was signed with invalid entitlements" appears. And yes, I have an ad hoc provisioning profile installed. I've tried to add "Entitlements.plist" with "get-task-allow" checked but with the same result. Has anyone been able to run the example? If that is the case, provide me with instructions on how you got it to run, please. URL: http://developer.apple.com/iphone/library/samplecode/GenericKeychain/index.html

• Django BigInteger auto-increment field as primary key?

  - by Alex Letoosh

  Hi all, I'm currently building a project which involves a lot of collective intelligence. Every user visiting the web site gets created a unique profile and their data is later used to calculate best matches for themselves and other users. By default, Django creates an INT(11) id field to handle models primary keys. I'm concerned with this being overflown very quickly (i.e. ~2.4b devices visiting the page without prior cookie set up). How can I change it to be represented as BIGINT in MySQL and long() inside Django itself? I've found I could do the following (http://docs.djangoproject.com/en/dev/ref/models/fields/#bigintegerfield): class MyProfile(models.Model): id = BigIntegerField(primary_key=True) But is there a way to make it autoincrement, like usual id fields? Additionally, can I make it unsigned so that I get more space to fill in? Thanks!

• Definition could not be found error compiling ClassReference in CSS file to Swf file

  - by Roaders

  Hi All I am compiling my css files to swf files and loading them at run time. I have no problem compiling these and using ClassReference statements most of the time: .miniCashLadderGridStyle { color : #2a2a2a; backgroundAlpha : 0; borderSkin : ClassReference("mx.skins.ProgrammaticSkin"); headerSortSeparatorSkin : ClassReference("mx.skins.ProgrammaticSkin"); horizontalSeparatorSkin : ClassReference("company.assets.GridHorzDivLine"); verticalSeparatorSkin : ClassReference("company.assets.GridVertDivLine"); } That works fine. The assets come from a seperate swc, However this: header-background-skin : ClassReference("company.view.grid.skin.HeaderBackground"); Does not work. The difference is that the HeaderBackground is a class in the same project as the css file. That does compiel fine if I move the style into my mxml file though. I wonder if the compiler uses different source paths when compiling the css fiels or something. This is in FlashBuilder 4 build 269271 SDK 13963

• How get Android 2.1 SDK to recognize new class: SignalStrength

  - by Doughy

  The new Android 2.1 SDK (version 7) has a new class called SignalStrength: http://developer.android.com/reference/android/telephony/SignalStrength.html I updated my SDK in Eclipse to include the 2.1 add-on, and now I am trying to use this new class. However, when I go to do an import android.telephony.SignalStrength, it can't find it. Do I have to somehow reset my project to refresh the SDK so it knows about the new libraries? How can I get it to recognize this new class? Thanks.

• VS2010 Intellisense on class files

  - by rlb.usa

  I have a Web Application Project that I'm working on. My solution looks like this : ./MyProject/ ./MyProject/dataobjects.cs <- no intellisense ./MyProject/sqlquerying.cs <- no intellisense ./MyProject/default.aspx <- intellisense works here ./MyProject/default.aspx.cs <- intellisense works here ./MyProject/mypage.aspx <- intellisense works here ./MyProject/mypage.aspx.cs <- intellisense works here Visual Studio 2010 doesn't give me any intellisense options when I work on non-code-behind files like Business Logic Layers and Data Logic Layers . In VS2008, I placed these files in the App_Code folder and intellisense worked fine. What can I do? Is there a specific folder I need to put these files in to get intellisense?

• How to retrieve path for a file embedded in Resources (Resource Manager) - .net C#

  - by curiousone

  Hi, I am trying to retrieve file path for a html file that is embedded in resource (resx file) in VS2008 C# project. I want to give path of this file to native webbrowser control (PIEHtml) to be able to navigate (DTM_NAVIGATE) in my application. I know I can pass the string to this control using DTM_ADDTEXTW but since html text size is so big, I dont want to pass string to the control. I need to somehow extract the file path for this html file embedded inside resource manager. I tried using but this does not give the file path of html inside assembly: private ResourceManager resManager = new ResourceManager("AppName.FolderName.FileName", System.Reflection.Assembly.GetExecutingAssembly()); this.lbl.Text = resManager.GetString("StringInResources"); and also read Retrieving Resources in Satellite Assemblies but it did not solve my problem. Can somebody please provide info as to how to achieve this ? thanks,

• jQuery UI Draggable-Droppable overflow:visible

  - by Jeff

  Sadly, I am unable to provide any JSFiddle for this issue, as I cant seem to reproduce it outside my project. I have a container where there are some boxes, that can be arranged using drag and drop, by utilizing jQuery UI. The problem is, that the container is overflow:auto; but it needs to be overflow:visible;, but if I do that, jQuery UI malfunctions. When a box drag is initiated, it will immediatly jump up aproximately 400-500px. This is how the draggable is created: $(".draggable").draggable({ revert: 'invalid', // when not dropped, the item will revert back to its initial position containment: '#editContainer', // stick to demo-frame if present helper: 'original', cursor: 'move' }); Is this a bug with jQuery UI, or can this be fixed on my end? I apologize for the lack of source code.

• Ruby on Rails Foreigner plugin not working for SQL Server

  - by Earlz

  Well, now that I've finally got my stupid ODBC stuff configured, I took a schema.rb file that I dumped from a Postgres database and did a db:schema:load on it in a Rails project configured for SQL Server. Well, it sets up all the schema in the SQL Server database except for a minor detail: No foreign keys are created. The rake command doesn't show any errors and does say it is adding foreign keys. But they don't actually get added. This is the last bit from the command: -- add_foreign_key("workhistoryform", "form", {:name=>"workhistoryform_form_rid_fkey", :column=>"form_rid", :primary_key=>"form_rid"}) -> 0.0002s -- initialize_schema_migrations_table() -> 0.0092s -- assume_migrated_upto_version(0) -> 0.0942s [earlz@earlzarch avp_msql_migrations]$ So what is the problem? Does the Foreigner plugin not work in SQL Server? If it didn't I'd expect to see an error or something...

• Django - categories & sub-categories

  - by Bluey

  Some advice needed on how I can structure my models for my site. I have seen this post from Django project but still a little lost. Also come across Django-MPTT - but that's no help and possibly overkill. I'm looking to have categories & subcategories that are shown in the URLs like this: mysite.com/Level1/Maths/Calculations/Addition/ mysite.com/Level3/English/ mysite.com/Level2/English/Storytelling/ In my admin interface I'm looking to have drop downs for each level of category or subcategory. Also at each level I will be querying items (another model) like get all items that have the category 'Level1' AND 'Maths'. There could also be a situation where I have five or more subcategories. How is it best to create my models for best performance? It it worth using tagging instead?

• change the class loading order google app engine java

  - by Shekhar

  I am trying to create an application on google app engine using struts2. Struts2 internally uses freemarker .One of the Freemarker framework classes suppose X internally uses a class javax.swing.Treenode which is not in google app engine jre white list. Now in order to run my application i created a new class X in the same package structure as it was in freemarker framework and copied the class to WEB-INF classes.Then When i run my application it run fine. The problem is that i want to take out the class X from my application sourcecode and move it to newly created jar and place it in WEB-INF/lib folder. So that i can reuse the code in multiple project and my code remains clean of the freemarker code. But when i run the application it picks the old class X from the original freemarker framework.As a result i get ClassNotFoundException. Can anyone provide any help such that i can change the ClassLoading order such that my jar containing X class loads first.

• Rewriting a Subdomain with mod-rewrite

  - by resonantmedia

  I have a project that uses the moodle library. I had to change the URL from moodle.example.com to learn.example.com, due to a client request. I thought this would be an easy change, but alas moodle inserts all links and images in with the complete url instead of the relative url. Is it possible using mod-rewrite to point all requests to moodle.example.com to learn.example.com and maintain the query string? Example: I want a request to: http://moodle.example.com/course/view.php?id=2&topic=1 to go to http://learn.example.com/course/view.php?id=2&topic=1. Is this possible? Thanks, Josh

• Deploying a PyQt application on Windows Vista x64

  - by Skilldrick

  I'm working on an application for a client/friend using PyQt. I've been working on Linux and testing on Vista, but the target computer is Vista x64. Now, Python comes with compiled binaries of Python 2.6 for 64 bit Windows, but Riverbank don't provide 64 bit binaries for PyQt. I don't have much access to the target computer, so I can't really go through the hassle of compiling PyQt. This Google code project might be the solution, but I'm not sure if it's going to work. Can I use something like py2exe from 32 bit Vista, or would I have to have to make the executable from a 64 bit machine with PyQt 64 bit installed? Basically, am I going to have to compile PyQt on the target machine?

• How to create a custom yaml config file in Symfony

  - by Guillaume Flandre

  What I want to do is quite simple: store data in a custom config file that I want to read later on. I created my file something.yml that I put in the global config directory. It looks like that: prod: test: ok dev: test: ko all: foo: bar john: doe Then I copied the config_handlers.yml and also put it in the config directory and added the following at the top of the file: config/something.yml: class: sfDefineEnvironmentConfigHandler param: prefix: something_ But if I'm calling sfConfig::get("something_foo"); I keep getting NULL. What did I do wrong? I just want to read values, so no need to create a custome config handler, right? I've read the doc here: http://www.symfony-project.org/book/1_2/19-Mastering-Symfony-s-Configuration-Files even though I'm running 1.4 (I don't think that changed since then). Edit: Of course I can use sfYaml::load() but I'd like to do things in a better way.

• Can I directly use JAVA-sourcecode directly in SCILAB, or Is there another way to connect both?

  - by Andreas Hornig

  Hi, a friend of mine uses SCILAB for doing his mathematicall "homework" for his studies and he told me, that it should be possible to use JAVA-sourcecode diretly in SCILAB. The background is that I presented my current JAVA project and I would like to plot this in 3d, but I haven't done graphical output so far. And he proposed to let SCILAB do the 3d plotting, because there are some ready to use plot scemes implented. But he couldn't tell me how to achive this, so that's why I'm here :). So my first question is, IF this is possible to directly use JAVA-Source code in SCILAB or at least to some kind of connection between both? And how this is done! :) Thank you in advance, Andreas

The problem is when the anonymous method is called, then the component variable is always the same element (as coming from the outer scope from IEnumerable) foreach (ISupportsOpen component in something.Site.Container.Components.OfType<ISupportsOpen>()) { MyClass m = new MyClass(); m.Called += new EventHandler(delegate(object sender, EventArgs e) { if (component.CanOpenProject(..)) component.OpenProject(..); }); itemsList.Add(m); } How should it be solved, please?

• How do you use Linq2Sql in your applications ?

  - by this. __curious_geek

  I'm recently migrating to Linq2Sql and all my future projects would be done in Linq2Sql. Having said that, I researched a lot on how to properly plug-in Linq2Sql in application design. what to put at what layer ? Should I use DTOs over Linq2Sql entities ? I did not find any rock-solid material that really talked about one single thing and everyone had their own opinions and I found all of them justified right from their arguments. I'm looking forward to your ideas on how to integrate/use Linq2Sql in projects. My priority is maintenance[it should be maintenable and when multiple people work on same project] and scalabilty [it should have scope of evolution]. Thanks.

• How can I play compressed sound files in C# in a portable way?

  - by skolima

  Is there a portable, not patent-restricted way to play compressed sound files in C# / .Net? I want to play short "jingle" sounds on various events occuring in the program. System.Media.SoundPlayer can handle only WAV, but those are typically to big to embed in a downloadable apllication. MP3 is protected with patents, so even if there was a fully managed decoder/player it wouldn't be free to redistribute. The best format available would seem to be OGG Vorbis, but I had no luck getting any C# Vorbis libraries to work (I managed to extract a raw PCM with csvorbis but I don't know how to play it afterwards). I neither want to distribute any binaries with my application nor depend on P/Invoke, as the project should run at least on Windows and Linux. I'm fine with bundling .Net assemblies as long as they are license-compatible with GPL. [this question is a follow up to a mailing list discussion on mono-dev mailing list a year ago]
