Having recently read "Growing OO systems guided by tests", I am very impressed with the windowlicker testing utility for java/junit. Basically it wraps the GUI and GUI-interaction with drivers and gestures, so your integration/end-to-end tests can be written neatly like:
//setup
ui.enterUserDetailsFor(newUser)
ui.sendForm()
//assert
ui.showsWelcomeMessage()
All swing-gui-thread synchronization and finding widgets etc is nicely isolated in the framework. Exactly this sort of higher level testing is something I really miss in my current wxPython project. Is there anything at all similar for wxgtk/wxpython?
What I can tell from the windowlicker source it builds on java.awt.robot, if there isn't a windowlicker, is there anything like robot?
I haven't heard of anything specifically for wxPython. You can use the Widget Inspection Tool for some of the stuff you are talking about though. See here:
http://wiki.wxpython.org/Widget%20Inspection%20Tool
There's also the Sikuli project which is GUI-agnostic:
http://groups.csail.mit.edu/uid/sikuli/
Hopefully one of those will help you out.

At first I was excited about working on open development projects for Octave related to implementing programs heavy in mathematics and physics, such as delaunayTriangulation class, but after talking to a few octave maintainers I have come to the sad conclusion that Octave will be complete after classdef is complete, at which point physics or mathematician like programmers will no longer be needed to build new functionality to Octave. Is this true?
I have followed your thread on the Octave maintainers mailing list and I think you have misunderstood this quite badly.
Once classdef gets implemented, the problems won't be solved, quite the contrary. It will allow for many problems to be solved, which can't be done just yet in a Matlab compatible way. There are 2 things here:
you may have felt that there's no problems left to solve after seeing many suggestions of libraries that already solve the problem. That doesn't mean they will be used. Even if licensing allows it, there comes a point where having to "reshape" the data in Octave into whatever form the other library uses it, is just too much and a native interface is preferred. This is specially true in Octave because it's mostly written in the Octave language which allows for users to participate in its development.
Even if an external library is used in the end, remember that "the devil is in the details". Implementing an interface between Octave and an external library is not a trivial problem.
When classdef is complete, the work will start, not finish. And classdef is already working on the development version, so if you are interested in those classes, you could start implementing them there and they'd be released with the next version. To continue development of classdef, Octave needs that people it, so that it's problems can be found. And the delaunayTriangulation class requires classdef. It looks like a great pair, that should be developed together.
Does anyone know if there is a media formatter out there to support the jsonapi.org spec (application/vnd.api+json).
If not has anyone started (or looking at starting) a project to implement this?
For the record, as of today the answer seems to be no. Best I could find was this guy: http://www.emadibrahim.com/2014/04/09/emberjs-and-asp-net-web-api-and-json-serialization/ and that only tackles a tiny part of the problem.
I've been trying this for a while…unfortunately I tried to make something that was really smart and would automagically handle a data model from Entity Framework with almost no work. I was getting close to thinking about releasing it...and then I found out they changed a bunch of stuff in EF 6 (all models are supposed to be POCOs and the context is now a DbContext instead of an ObjectContext) and I'm probably going to have to essentially start over…which is why I started looking again to see if someone else was doing it and found your question.
Let me know if you're still looking for this, and I'll keep you updated.
UPDATE
I've just published a codeplex project that aims to provide exactly what I've described above. It's called JSONAPI.NET and while it's very early, it already does quite a bit. Documentation is sparse, and I don't have NuGet packages yet…but take a look everyone and see if it's useful for you. Feedback is encouraged! You can contact me from the project page in the link.
Cocos2d-x 3.0 alpha was released for some time now. What was improved over cocos2dx-2?
The features list is quite important, but in terms of performance are there new limitations/improvements?
Have you noticed real improvements in performance, development patterns, APIs and support?
I've been using it recently and from what I've noticed the main differences are that everything is namespaced now, so you don't have to deal with the prefixed names that came from the objective c patterns, so cocos2d::Point instead of CCPoint (especially for enums, (Texture2D::PixelFormat::RGBA8888 instead of kCCTexture2DPixelFormat_RGBA8888)).
Also some of the event stuff now has support for c++11 lambdas.
A more complete list of the changes can be found here: http://www.cocos2d-x.org/wiki/Release_Notes_for_Cocos2d-x_v300
but for the most part of using it myself, it's just made to feel more like C++, instead of like objective-c.
I have switched and am finding it pretty stable. The main advantages so far ...
Real buttons, instead of menus
Real-time spritesheets
SpriteBatchNodes are no longer recommended and I did see a drop in draw calls where I not optimized
less objective C patterns.
more modern. namespaced instead of 'CC'. C++11.
more platforms supported
Main disadvantages for me:
EventListener pattern. I can't figure out how to get touch input to affect any objects other than the Node that triggered the event.
We use a lot of text-only buttons for debugging and they are hard to lay out :)
Lack of documentation and example code. For example, I could not find any documentation of how to use the Layout class anywhere.
It is a lot of work porting, but for us we had to decided to risk it since we would end up maintaining an out-of-date code base. It took about 5 person-days to port our game over. The game is now stable and we did not run into a single bug in cocos.
I think its C++11
auto
lambda
And it has no unnecessary use of prefix CC
One of the changes that happened between Cocos2d-x 2.1.5 and 2.2 was the removal of templates for projects in XCode (I do not know if project templates existed in VS, etc).
The new build system creates projects under the Cocos2d-x installation (at least on Mac) and that is where the project files appear to reference them. This makes it very difficult to move the project without hand tweaking. It also makes configuration management more painful, depending on how you set up your system (e.g. a root/tree like svn or a "drop it anywhere" like git).
Also, the Cocos2d-x library is built as that, a library. In previous incarnations, it was placed directly into the project. On one hand, if you don't alter the root library code, this makes good sense. On the other hand, if you occasionally tweak things for a specific project, you have altered all your projects that depend on it. Yin/Yang.
I'm still very positive on Cocos2d-x. I have not upgraded to 3.0 or 2.2 yet. When it matures a little more, I will switch over, regardless the changes. For what I need, I'm pretty sure it will still get the job done (well).
We have a group of developers moving from C++ to C# and WinRT. We used D'Oxygen as part of our C++ developer builds, and I'd like to continue to have document generation as part of the developer build in C#/WinRT.
It's easy to turn on XML Doc generation, and I believe that will provide warnings for malformed tags, but without actual HTML output, I think our developers will be missing valuable feedback.
Looks like NDoc is now defunct, and I took a quick look at Sandcastle, but found it rather complex. Ideally, I'm looking for something that doesn't unduly burden developers, or require them to remember extra steps as they edit, build, test, and commit. In other words, the best solution would be something that "just happens", like a post-build step, and doesn't add significantly to each developer's build time.
If anyone has had some experience doing this in C#/WinRT, I'd sure like some advice.
Thanks in advance!
Get Sandcastle Help File Builder.
Create a help project for your library in the Visual Studio solution.
Remove Build check mark from Debug solution configuration to build the documentation project only in Release configurations, since Debug is most often used during development. For release build testing or performance testing you can either create another solution configuration or simply switch the option back and forth.
Build the documentation once
Include the documentation file in the solution so it shows up in the Pending Changes window when the file changes.
Kindly ask your developers to build with the release configuration that updates the documentation before check-in or use any other policy to require updating the documentation.
I don't think it makes sense to build the documentation all the time, but it helps to make it easy to do so that when you actually need an updated version - you can build it really quickly.
You can also make sure to use FXCop or StyleCop (forgot which) and configure it to treat missing XML documentation warnings as errors - at least in release builds. Doing it for debug configurations might slow down development and make changes difficult since developers often want to try things out before committing to a final implementation worth documenting.
EDIT*
Sandcastle provides various output formats as shown in the project properties:
I would like to mention ForgeDoc (of which I'm the developer), it could be what you are looking for. It is designed to be fast and simple, and it generates proper MSDN-like HTML output. It also has a command-line interface so you can just call it from a post-build event command in Visual Studio.
I think you should give it a try, as I would really like to hear about your thoughts.
I'm starting to use Dojo; this is (essentially) my introduction to AJAX. We have a Java backend (torque / turbine / velocity) and are using the jabsorb JSON-RPC library to bridge Java and Javascript.
What do I need to know? What is the big picture of Dojo and JSON, and what are the nasty little details that will catch me up? What did you spend a couple of days tracking down, when you started with Dojo, that you now take for granted? Thanks for any and all tips.
The first thing to do is get familiar with the Dojo Object Model. JavaScript does not have a class system so the Dojo toolkit has created a sort of "by convention" object model that works rather well but is very different to how it works in Java for example.
The reason I suggest getting familiar with it is so you can dig into the code base whenever you start experiencing issues. The documentation available has improved significantly over the past year, but every now and then I find myself having to work out a bug in my code by learning exactly how the Dojo code involved works.
Another tip is to make use of the custom build feature which will significantly improve performance once your application is ready.
As a general tip on DHTML programming, use firebug (a plug-in for Firefox). It allows JavaScript debugging, DOM inspection, HTML editing in real-time and a whole lot more. I've become totally reliant on it now when I'm working in DHTML!
Good luck!
I too just dove head first into Dojo, they have a good API documentation at http://api.dojotoolkit.org/. Even Dojo Campus has some good examples of the plug ins.
If you ask me O'Reilly's Dojo: The Definitive Guide is the best Dojo book on the market.
I also would like any tips and pointers from the Dojo masters.
Cheers
Make sure documentation you read pertains to as recent a release as possible, since a lot has changed very quickly in the Dojo architecture.
Also a great way to see how some Dojo or Dijit widget is used is to look at the source code for the tests - for example, the DataGrid has poor documentation but the tests show a lot of use cases and configurations.
Sitepen is a good resource for Dojo articles.
Also, read up on Deferred (andDeferredList), as well as hitch() - two extremely flexible and powerful features of Dojo. SitePen has a great article on demystifying Deferreds.
Check out plugd, a collection of Dojo extensions that make some things more convenient or adds some clever functionalities to the language. It's made by one of the core Dojo authors so it's rather reliable. It even brings some jQuery niceties into the framework.
Some more things: look into data stores, they're very useful and a much cleaner way to handle Ajax. DojoX has a lot of nice ones too, just remember that DojoX ranges in how well documented or how experimental the components are. Learn the differences between dojo.byId and dijit.byId, as well as the HTML attributes id versus jsId (again, Sitepen has an article).
A couple of things that caught me when I started writing widgets where:
[Understand what dojoAttachPoint, dojoAttachEvent, containerNode and widgitsInTemplate do][1]
have a firm grasp of closures,
Get your head around deferreds
understand ItemFileReadStore, ItemFileWriteStore and stores in general
You can look at stores like a ResultSet (sort of) as well you can data bind them to widgets.
With these major concepts you can start to put together some compelling applications.
Generally what I do is I build a JavaScript facade around my service calls and then I will scrub the response into a store by attaching the first callback in the facade, that call back converts the results into a store and then returns it. This allows me to not hard bind my services to Dojo constructs (so I can support mobile, etc.) while also retuning the data from the facade in a format that data aware widgets expect.
As well if you are doing Java service development you my want to look into JAX-RS. I started out using JSON-RPC which became JABS-ORB but after working with JAX-RS I prefer it, as it integrates well with JPA-EJB and JAXB.
First read how to configure Dojo in your application. Try to understand basic structure of Dojo like if we are writing dijit.form.Button or dijit/form/Button it means Button.js resides in dijit/form folder. Try to understand require, define, declare modules of Dojo. This is enough to start Dojo Toolkit.
Very important fact, indulge with your own sample project using Dojo.
