Well, perhaps this is silly but I wonder is it possible, to transfer a web app built in Javascript with some html and css to linux platform?
I made a youtube player smth like youtube client, and I want to use on my Ubuntu 15.04 OS, as an app.
Here is a preview:
and I would love it if it would look smth like this:
I know that this Google Mail is just loaded from a web, but I want to make it accessible from my Ubuntu. Just instead of this google I ant that my app gets in. I hope you understand...

As has been pointed out, JavaScript and HTML5 don't "natively" run on Linux -- so you'll have to find an application to wrap yours. Plenty of these things exist -- Electron is very popular, as is nw.js.

Well, I'll try to take a stab at answering your question:
If you want to run it natively on linux without any other application being involved the answer to your question is not without rewriting it to some other language. Linux does not run javascript natively.
If you want something thinner then a web browser perhaps something exists to run your web app for you, but it's essentially going to be a light web browser. If you want to run javascript there will always be some other application between you and the kernel unless the kernel specifically supports javascript which Linux does not (and AFAIK no kernel does).
So in short, based on what I think you're asking for, no.

What link should be used and how to determine the right one for every OS?
iOS
Android
Windows
macOS
Linux
Is this universal for all operating systems?
<!-- Deep link URL for existing users with app already installed on their device -->
window.location = 'yourapp://app.com/?screen=xxxxx';
this is named Uniform Resource Identifier (aka URI).
The beginning of your URL "yourapp" would be a scheme. There are some schemes which are much used, for example ftp:, file:, mailto:, tel:, git:.
There are a lot of it but the support is very limited and as you said, depends on the browser and what software the client has installed on it. So, the scheme has nothing to do with the OS when you use a predefined scheme. If you want to have your own application you need to tell the OS "Uhm, hi there, could you please listen to that scheme" (As example in Windows with the Registry). And you can't do that from the browser because that would open a lot of possible attacks from the browser to your OS.
So to answer your questions: The right one for every OS? Is this universal? Yes, You need only one scheme, as it does not depend on the OS.
Think about it: What do you want to archive? A mailto:? Just do it. A ftp:? Well, your client has to have a FTP-Client with URI-Support. A custom app, like myapp:? That's a lot of work and I wish you good luck with that as it is a custom program for every OS.
If interested, see this link for a list of all schemes.
I hope, I could help you. Have a nice day :)

I used node for 1 year, but only for writing server applications. I am now interested in making an application that's usually written in a language like C or C++, so I am not sure if it's possible, for example, to write a keylogger or simillar applications using JavaScript and Node.js?
Yes, you can use Node.js to write desktop applications which can act as a keylogger, communicate with device drivers and other system resources.
Most of the system interoperability has gone into providing cross-platform support for particular system event notifications and I/O. Be mindful that there are tall stacks for reading keyboard events that differ from platform to platform, so you will probably want to take a look around the Node.js ecosystem for packages like node-ffi, which may assist you at accessing system resources from your application's event loop.
Should you want to write your own system bindings that are exposed to V8 and accessible by your Node.js application, there is excellent support for going native, from packaging to creating asynchronous events for your Node.js application.

Some malware is injecting this script somewhere in my wordpress main page. I already went through all files in Editor but I find nothing about this. Any idea where can I find it? Its driving me crazy.
This script is injecting adware popups in my wordpress website.
Try downloading the whole theme folder and plugins folder (with all plugins). Then you would need to run search across all those files. Usually malware code is using eval functions so you should search for eval across all those files. Searching one by one would take forever so use grep tool.
For windows I would recommend windows grep
http://www.wingrep.com/
For Mac I would recommend visualGrep app which is paid app and costs around 2 bucks but totally worth it.
If you have linux then you would need to find the software yourself or you can run such a search from the command line. (Actually you can use CLI on any system but I just prefer having app with GUI fur such task)
in 99% of cases (from my experience) you will find something like:
eval(base64_decode('dsalkndsalndsnldakslasdkn'));
That will be the malware code and you should take care of it (remove). If the code is in the plugin, then you should get rid of such a plugin probably.
Hope this helps.

what is the difference between LAMPP and METEOR [closed]

Can anybody explain me what is the difference between LAMPP and METEOR js framework?
Thanks in advance.
There is quite a big difference between the two.
LAMP:
This is a stack that originally (and still largely) stands for Linux Apache MySQL and PHP
The alternative of windows is called WAMP.
The linux part is the system the stack is running on; Apache is a server system where you can store and access your websites and apps; MySQL is the type of database(Relational Database); PHP is the server-side language you use to create these dynamic sites (you can also use python or perl).
The community is much larger and you can get support everywhere as it has been around longer than Meteor
If you run a linux os, you can literally download the apache server and host it on your computer see: http://httpd.apache.org/
Meteorjs
Meteor is a full stack platform that allows you to write all your code in Javascript. This means you can write the front end in Javascript, then turn around and also write the server/backend using the same JavaScript! Literally write once, run everywhere
Meteor allows you to write an app in very short amount of time as you are using just javascript.
-What really makes Meteor stand out is their "realtime" way of doing things. With mete0r, everything is reactive. When a change happens in the server, it is immediately reflected on the front-end without refresh or waiting at all!
Meteor apps come with Mongodb (NoSQL) already set up as your database system as opposed to MySQL used by LAMP. Meteor goes the extra mile by also creating a small database in the front end of your app and whatever changes you make are performed in this mini-mongo database which automagically synchronizes with the server and updates it. METEOR DOES ALL THIS FOR YOU.
-Learn more at https://www.meteor.com/ and this https://www.youtube.com/watch?v=RpQTPWvD6HA offers a great intro.

JScript user asks how to build a a home made JavaScript interpreter to avoid limitations [closed]

I know how to do my jobs by C++. I like to move most of
them to Windows Script Host JScript. But Windows JScript
doesn't do many important things.
Many JavaScript kernels are open source, and we have node.js,
processing.js already.
So we need to be able to build our own JavaScript interpreter
so as to bypass JScript. This sounds true for desktop applications
, right?
I need some hints to start it. It's worthy even if it takes years.
JScript limitations are :
1. can't access hardware.
2. can't do things that need administrator privilege.
A JScript wrapper like xNeat http://www.xneat.com helps JScript to call APIs. But it does not work with WinIO (access I/O ports and physical memory) because WinIO needs administrator privilege that is not allowed by JScript.
I'll try to compile V8 or the likes and remove restrictions it intentionally made for security then add some low level interfaces to call Windows APIs, which JScript can't do. I think this is cool. Maybe I don't even need to do that again because somebody already done that?
You seriously need a lot more research... I'll try & save a few flops of Google:
JScript != JavaScript. Assuming you are using them interchangably
without knowing about the existence of proprietary JScript from
Microsoft..
Javascript was never meant to do things you mention as limitations. It's supposed to run in web browsers & obviously a random website whose JS it is, should not be able to access/execute anything in the user's machine.
Although contrary to belief that JS does not need to touch the file system, the filesystem API was brought in. I feel, that expands the boundaries wide enough for any web application to leverage on.
Besides, you can always develop desktop apps for windows 8 in JS, by the libraries exposed by Microsoft, but that's another story.
