I've been working on a project (you should probably see the link to better understand what I am talking about). To make things better, I decided to make a like system.
Each posts contain a like button and a number next to it that indicates how many people liked the post.
Like (4)
The current one in my project is just plain text with an empty link, and the number is a dummy.
Like (4)
Is it possible to actually make the like button actually work? What would I need to use?
I think you need php/SQL to keep track of the votes made. So you need to learn php and SQL or rely on an extension someone else made. If you happen to use one of the more popular CMS's (Joomla/Wordpress) you can probably get it without ever having to worry about the coding.

I need help with creating a survey app. My idea is for the app to display questions and have users click buttons to answer. At the end, the app should show each user which user had answers closest to theirs. I need help with the following things:
*How to set up the questions and buttons for the answers
*How to compare all the answers and show each user at the end
*How to make it so there is a separate url for each survey being taken
Answering any of these questions would be very helpful.
For grouping the participants by how close their answers are, you could use the k-means clustering algorithm, of which there's already a JavaScript implementation you could use.
Well, I don't see where Socket.io fits, other than that you could use Survey.js Library to help you build the interface, store the data in the same format, JSON, in MongoDB. There you can group like here, returning the documents data of same value.

I have a really really big question which is how to write a social networking website like facebook? I want to know which language should I use and why. And also the relationship of them or the whole structure of website. Only a general idea of blue print will be all right. However I don't mind if u can tell me things in detail. Thanks in advance.
Simply put: You can't realistically without a huge team of experts and lots of money. If you're a full-stack developer I'm sure you can pull off a website that has user profiles and a commenting system just with HTML, CSS, javascript, AJAX, and something like PHP/MySQL on the backend (lots of options here). Facebook is obviously a lot more complicated than that though, especially with all the asynchronous features going on such as the chat system.

I'm making a (web) app for a school project, using Phonegap. I'm writing IT in Javascript, HTML and CSS, and I am very new to coding.
My question seems to me to be pretty straightforward, but I can't seem to find any solution on the internet.
I have finished my homepage, but now I need a button which directs you to another page (the menu), from where you can go to other pages within the app. But I just can't find out how to make different pages, and how to direct users to those pages.
There are two ways I see you can do this. Either make a new program (new HTML file) and make the button redirect you to that or completely clear the page using document.write("") and rebuild it.

Here is my goal:
Create some JavaScript action (some function call) that will be timed perfectly between two different clients.
Explanation:
I want a function to be called exactly on the same millisecond on two different browsers/computers no matter when the client accessed the web page.
I thought about creating a time base using the server time but im not sure this will work.
I think you should be using something Node.JS or APE (Ajax Push Engine) to achieve this.
so you want to do like this scenario: user come visit your webpage and he has to wait few seconds that page is shown?
This is useless to do in my opinion, unless you want to flood server with tons of requests..

I made a website that does absolutely nothing, and I've proven to myself that people like to stay there - I've already logged 11+ hours worth of cumulative time on the page.
My question is whether it would be possible (or practical) to use the website as a distributed computing site.
My first impulse was to find out if there were any JavaScript distributed computing projects already active, so that I could put a piece of code on the page and be done. Unfortunately, all I could find was a big list of websites that thought it might be a cool idea.
I'm thinking that I might want to start with something like integer factorization - in this case, RSA numbers. It would be easy for the server to check if an answer was correct (simply test for modulus equals zero), and also easy to implement.
Is my idea feasible? Is there already a project out there that I can use?
