Is Corba Legacy?
I am asking this question because I don't see any new books on CORBA in recent years. I am really new to CORBA, and I am not sure if I still need to learn it.
In what situation, CORBA is still useful?
My last job at a defense contractor used CORBA heavily. (And ACE/TAO)
I have only used it at one job of about 8 in the last 15 years. It was talked about at a few other places I was at - but none used it.

At the moment I can not find a somewhat up to date version of mdc for dart. I can find for example https://pub.dev/packages/mdc_web and https://github.com/dart-lang/angular_components but both are really far away from an up to date implementation of Material Design.
Is there a library apart from this I can use, so that I can use up to date material design with dart?
The two links you posted have different use cases. The former is for vanilla web dev using Dart, and probably your best bet unless you plan to use AngularDart. Even though it has not been updated in over a year, I don't think there is anything newer. You could try cloning the repo and adding support yourself for the missing or outdated components which you desire.
AngularDart is (in my opinion) a great framework. The latter link you posted is specifically for use with AngularDart. Last update it was 15 days ago. This project is maintained by Google and I think it is safe to say that Google is by far the largest user of AngularDart. Their material design components which you linked to are going to be your best bet in this case.
Generally speaking though, using Dart for web dev never achieved widespread adoption, so there are not large communities with a lot of active package maintainers.

Coming from Android, I got used to Dagger as my main DI framework.
Recently, I joined a new iPhone project written in Objective-C which have no DI framework.
I would like to add one to our project, and I wonder which one is the best one to use, when it comes to simplicity and performance.
I would like to hear your opinion and experience.
Thanks!
Dependency injection is a popular design pattern in many languages, such as Java and C#, but it hasn’t seen widespread adoption in Objective-C (yet!).
This is an excellent read to get you started on DI is Objective-C. Additionally, you'll find this, this & the Grand Daddy this indispensable for DI in iOS.
This framework seems to be making a lot of noise these days.
In my personal experience, more than anything else DI helps you a lot in testing. It's not all or nothing approach (which is common for many design patterns) allows for easy, no-cost adoption & definitely valuable returns.

I have just finished a year of university and learnt how to write nice applications with C++, OpenGL and Qt.
I was just about to start learning Objective C and Cocoa. This seemed optimal to develop iOS & Mac apps since Objective C was, like C++, a variant of C, Cocoa would allow me to make nice UIs and I could continue using my good OpenGL knowledge to do 3d graphics.
However, Apple has recently announced that many things are changing. Most importantly, they have announced that there is a new language called "Swift", and that they are replacing (from what I understand) OpenGL with "Metal"
My question is, taking into account the lack of good books/comprehensive tutorials (I had found a great one for Objective C and Cocoa).
At this stage, should I wait for the release of XCode6 and iOS8 in fall, along with what I hope will be new books and tutorials on learning this new language and do something else in the meantime to avoid learning a defunct language, or should I learn Objective C anyway and then learn Swift when it comes out (and all these new things like Metal etc).
Is it worth deepening my OpenGL understanding in light of all this new stuff being announced?
I would advise learning Swift. It is proving to be popular, and there are some tutorials out already, such as this one (http://ios-blog.co.uk/tutorials/developing-ios-apps-using-swift-part-1/). Learning Objective-C will probably only be useful for a couple months, as Apple will probably push Swift as the main language. You can also get a good tutorial book by Apple on the iBooks store for free. Also, if you are a registered developer, you can get Xcode 6 and ios 8 now.

Are there any changes in Objective-C syntax and version overtime like Python and PHP. Can I use Objective-C that was taught 3 years ago and use it today to make my app.
As usual, it is always a balancing act. You can use all your previous knowledge, but you do not want to be stuck in the past, especially when there are advancements in the compiler every year. Things like ARC, removal of #synthesize for properties and the new literal syntax will improve your code greatly and save your time. I think before you start development, you watch the last three years' WWDC videos to see what's new in the language and compiler, and decide which you would like to learn. The changes are indeed rather minor in the grand scheme of things, so you have nothing to worry about.
Yes you can. Since then the objective c does not have changes that makes impossible to you to do your app.
But since then the iOS version suffered major updates (like ARC, iOS 7, etc) so I recommend that you take that in attention before you start your new app.
Same syntax. Just learn GDC, ARC and you ready to go. New APIs appearing in every new iOS version, but the language stays generally the same

Recently, I found an interesting Wiki/CMS/Database hybrid called Wagn, where the most important unit of information is the 'Card'. That terminology immediately made me think of Hypercard. As expected, there is some "Hypercard-ness" in that application.
Do you know of other web applications/frameworks with that "Hypercard-ness" thing, or if its successor still must be invented?
Note: I insist on web applications because I already know the desktop ones.
Check out Runtime Revolution at http://www.runrev.com they have a language/IDE that is the spiritual successor to HyperCard. They also have a product in beta called RevWeb which is a plugin not unlike Flash that is able to execute stacks.
Now more on the web framework front, checkout Rodeo at http://alltiera.com/ which is a HyperCard like web application that generates HTML/CSS/JS stuff for you.
I am a customer of Runtime Revolution but I haven't used Rodeo so I can only help with building web applications using RevTalk (like HyperTalk) and not with Rodeo.
There was http://tilestack.com for a while. Sadly it closed down again. It even imported HyperCard stacks.
I have found that quote from Dan Ingalls in the book "Coders At Work" (p.382):
"A decade or two ago there was Hypercard [...] It's really strange that that whole experience didn't naturally go right into the web. I think there's still a role to be filled there with tools as simple as HyperCard and as immediate as the web. It would be cool if it went that way.".
If one of the inventor of Smalltalk is asking that question too, I'm almost sure that there is no valid answers...
Anyone interested in inventing that future?
