We want to build an application using node.js, which we want to integrate with a payment gateway.
My though is, we will develop another application which will be PCI compliant.
So my main application doesn't need to be PCI compliant.
What are the different possible ways through which this can be achieved in node.js applications.
I found one node module - balanced.js which takes care of this issue.
https://docs.balancedpayments.com/1.1/guides/balanced-js/
Any other thoughts?
Balanced is just another tokenization solution which provides node.js integration. You'll find Stripe, BrainTree and BlueSnap do the same. They even offer hosted checkout pages to nearly rid you of the PCI compliance.
Please note that this is not a coding question so you might get flagged here :)

I am just wondering how rabbit is able to give each user a diffent broswer to use from a linux machine it seems like vnc tech but I dont know please let me know if you know how they are able to do that.
There is a somewhat detailed blog post about what their architecture was here: https://bloggeek.me/rabbit-webrtc-interview/
I will quote the relevant part for longevity:
We have two main stacks, one for audio/video and one for our business
logic:
Our audio/video stack is built in Java on top of Netty:
Our SFU allows us to use WebRTC with much larger groups than the
normal use case. For our shared viewing feature (called Rabbitcast™),
we had to build a native extension to capture and delivery an HD
stream with audio from our virtual machines. Both of them use our own
WebRTC server stack to talk to the clients. Our Business Logic stack
is built on top of Node.js using a promise-based approach to keep our
sanity.
Lastly we use Redis both for intelligent caching and pub/sub. MongoDB
is our persistent storage.
I am not sure about what exactly they are using but I have some ideas how it works yeah as you already said they are using virtual machines that ported to a html5 vnc client to control and stream video and audio. Other options might be using xpra,x2go,apache guacamole to port them into a html5 client again.
I am currently developing a Universal Windows 10 application that is planned to run both on the PC + Mobile and the Raspberry Pi 2.
I was wondering what would be the best way for these two apps to pass data from one another through a local network and not using Azure. It is required that for every transaction done on each device, it gets transmitted over to another.
We also need to remote control the Raspberry Pi 2, like manage the data and shut it down using the app.
We are planning to build a RESTful API that will run on the same local network to facilitate this but I'm not pretty sure what APIs to use for this.
What are the necessary APIs that will be good for this requirement?
Thank you very much for your help!
Depending on the size of what you transfer, I found this:
BackgroundUploader class
Windows.Web.Http namespace.
See https://msdn.microsoft.com/library/windows/apps/br207140?cs-save-lang=1&cs-lang=csharp#code-snippet-2
Have you seen those apps which explore your local network looking for devices?
Well, I would like to know how they get (mostly) the names of devices!
Does anyone know? Because I am building an application which needs to get (if possible) the hostname of the local devices..
Local network device discovery is often done by a zeroconf implementation (e.g. Apple services typically use Bonjour services to discover local device names).
If you wanted to explore this type of service for use in nodeJS, then maybe have a look at https://github.com/agnat/node_mdns. I've never used it myself but it does seem reasonably popular and stable.
Otherwise just do some research generally around zeroconf/mdns and make a decision based on your needs.
i am newbie to Linux platform, i am working on java technology.
what i have to do is : Having a program that running on mobile devices,that sends some data to my Linux machine, now i have to create a program in java that
listen to a particular port.
access data comes on that port(which is sending by mobile device)
save that data to the database.
response back to the mobile device.
i.e. i would make my Linux system as server that can listen from many clients(mobile devices), but not getting how to configure this environment... :(
i used cent OS 5.4 and
installed jdk1.6.0_24
any help would be appreciated.....
thanx in advance!

One of Java's greatest strengths is that you can pretty much ignore the host operating system as long as you stick to core Java features. In the case you're describing, you should be able to accomplish everything by simply using the standard Java networking APIs and either the JDBC to access an existing, external database or you could choose any number of embedded Java databases such as Derby. For your stated use case, that you'll be running the application on Linux is pretty much irrelevant (which should be good news... you don't need to learn a whole operating system in addition to writing your app ;-).
Here's a nice client/server tutorial, in that it is broken into steps, and adds each new concept in another step.
Here's another client/server tutorial with much more detail.
I would write it to accept one connection at a time. Once that works, I would study the new(ish) java.lang.concurrent classes, in particular the ExecutorService, as a way of managing the worker bee handling each connection. Then change your program to handle multiple connections using those classes. Breaking it up in two steps like that will be a lot easier.
Is it possible to write a mobile application with J2ME and whenever we want to implement a functionality not offered by J2ME call native mobile API ? (kind of like what is done with .NET, whenever you need something not provided, you just call the Win32 API from the .NET platform).
While JNI is not officially supported in J2ME, the Symbian implementation of J2ME obviously uses something very similar.
Since most J2ME APIs have a corresponding Symbian OS C++ API, what Symbian did (a lot) is develop adaptation layers between the 2.
Between that and the new modular architecture of the IBM J9 virtual machine (from Series60 3rd edition feature pack 2 onward), it is technically possible to add a new API to the virtual machine without actually needing to recompile most of a handset firmware.
However, third party developers simply are not allowed to do it without a lot of help from the handset manufacturer.
A loopback socket connection is the solution that people have tipically implemented to transfer data accross the language barrier. Large-scale deployment is not the easiest task, though, as you technically need to install 2 applications on the device. Once you understand the threading model of the Symbian J2ME implementation, you also realize how ugly and inefficient a hack it is.
When you reach that kind of issue, it's time to learn Symbian OS C++ and do it right.
No. That's not possible with Java ME.
Only sort of. Actually it is possible but not directly. You can write a native server that listens on a local socket and send requests to it from your Java MIDlet. Someone even released a framework to do this called MIDP-JNI (as opposed to real JNI). Obviously the form of the solution imposes some limitations on what you can do with it but it isn't actually impossible.
Be aware that using this approach can make your application much more complex to debug.
If you are specifically looking out for Nokia/Symbian, then APIBridge http://wiki.forum.nokia.com/index.php/J2ME_API_Bridge_Interface could be a solution. Typically it is the 'official' version of 'native server on local socket' kind of thing. The APIBridge is 'extensible' & you can write your own 'plugins' for your suitable 'low-level' task.
