I thought this would be the appropriate community to ask this question.
Back when Apple had their developer's conference over the summer, I was aware that they were going to make Swift open source.
I was under the impression that Xcode would not be ported to Linux, but I was under the understanding that some entity would create a development program to imitate Xcode.
Therefore, I am wondering about new developments in this situation.
Does anyone have any more current knowledge about this topic or any experiences with this?
There's a misunderstanding here.
Swift the programming language is open source.
It doesn't mean that iOS or OS X frameworks, like Cocoa, UIKit, etc, are available in Linux - Apple didn't announce that.
When you make an app for iOS using Swift, you have to import UIKit and other libraries - those are the iOS parts.
Swift is just the language - you can already make an iOS app with Ruby, Objective-C, JavaScript, etc, using these same libraries.

I am totally new to IBM lotus and domino notes. I just want to know how to connect IBM domino using java and what are the software I should have installed in my machine.
I gone through many websites but I didn't get any proper tutorial websites. currently I am referring to this page.
See my answer to a previous question here. That answer is broader than just talking about how to connect to Notes and Domino from Java, but it does include a good summary of the options you have from Java, and there's a reference to a very old book that you can download for free and is useful even if it is old. It has an excellent introduction to the principles of Notes and Domino in addition to a lot of information about the Java API. Once you've read it, you should be able to ask more specific questions and we will be able to help you with them.
As far as software goes, you may not need to install anything besides Domino Designer, but the truth is it depends on what environment you are going to develop in, what environment you are going to run in, and what choice you make about the different ways you can access Notes/Domino data from Java.

I am a newbie, I would like to know is it possible to build our own chatbot with angular and node.js? or What are all the information and technologies do i need to know to build my own customized chatbot?
To begin with you must know how does it actually work, i have written one in C# Chatbot using c# that can give you a basic idea, but proficiency in Javascript is must before you dig deep into these things.
Once you understand it you can go/learn the Artificial Intelligence Markup Language which is implemented on ALICE bot. There is also a new offering from Microsoft called Microsoft Bot Framework which can also be used with node.js.

I'm trying to develop a program like Windows Live Messenger for fun and personal use, using Node.js for the backend part of the messenger, and I've come up with two questions:
Is Node.js a good choice for backend?
Which language(s) should I use for the frontend part?
Thank you very much.
The backend language doesn't matter at all. Python, node.js, ruby, perl, c#, java, scala, golang, as long as you expose an interface that can be consumed by the client. (generally a RESTful web service interface, but it doesn't have to be.)
The frontend language depends on the target platform. You should use the native language for the client platform for the most streamlined development experience. C# for windows, Java for android, Swift for ios, javascript for web. If you want to "write once run anywhere" consider React Native.
But be aware that any "write once run anywhere" strategy is going to be plagued by hard-to-debug cross-platform bugs, in practice it's almost always cheaper to maintain a client for each platform, because it's easier to debug in the native language.
Another alternative is Ruby. With http://reactrb.org and rails you easily put together such a system. In fact the tutorial on the above site ( under docs/tutorial) is a simple chat app

Does anyone know any way how to port ZBar to NaCl? I'm making a pnacl project and need to read a QR code from a image.
I'm working on linux.
thank you for help!
The naclports project has many ports of libraries to Native Client, and some common infrastructure to do so. There isn't a port of zbar yet, but I've filed a bug for it here.
From the zbar README:
...
The scanner/decoder library itself only requires a few standard
library functions which should be avilable almost anywhere.
The zbarcam program uses the video4linux API (v4l1 or v4l2) to access
the video device. This interface is part of the linux kernel, a 2.6
kernel is recommended for full support. More information is available
at
http://www.linuxtv.org/wiki/
...
It sounds like it shouldn't be too difficult to get the scanner/decoder part ported. If you're interested in helping with the port, it's best to continue this conversation on the bug I linked above.

I would like to start a new Nodejs project soon, and I was wondering if I should try out Dart VM instead. I read that Dart VM is not finished yet, but I should already have everything I need (web server, sockets, files i/o), and I would enjoy discovering something new.
Does anyone have experience with both Node and DartVM, and can tell me what are the major differences/problems to expect, or if Dart VM is really not usable for real server side projects yet?
I'm not asking for your personal preferences, but for actual problems I might encounter based on your experience.
I worked on a small project, a few months ago, using Dart as a server side language. I really enjoyed it and didn't have any specific problem beside the occasional "there's no package for that" - there are way more packages for Node than for Dart. This could be something to consider for development speed (no need to reinvent the wheel). Other than that, everything went fine.
As a note, it is being used live by others: top 5 live websites already using Dart
