Is there any way to access the appear.in API (Developer page) via python? I want to create a user with the API and with that credentials, I then want to create multiple rooms. I am assigning each rooms to separate persons hence I am storing the details in a database. Any help?
Developer at appear.in here. The short answer is no, we don't support that kind of functionality. We aim to be a very low-end API solution for those that need video and just that. If you need more advanced support, I recommend checking out http://simplewebrtc.com/. They offer more advanced features, but requires a bit more work.
Feel free to contact us at api#appear.in as well with your questions, that will get you answers much quicker :)

I needed to implement speech 'identification', ie. Guess if the person who is trying to login, is actually him/her, by matching his/her voice.
To consider the case, where the app doesn't recognize the person, but the user is himself trying to login, then he may bypass it with a pin, setup during initial settings.
I am using Python and Flask, to build the webapp, and included javascript in the question, so as to know of possible ways in it too.
Till now, i read about it from some sources, but i couldn't arrive at a possible solution, on stack overflow, as well as 'few' blog posts.
The best 'possible' solution i could arrive at was Cognitive Speech Services by Microsoft -
https://azure.microsoft.com/en-us/services/cognitive-services/speaker-recognition/
I also thought of recording the voice using the Recorder.js, and analyzing at the server end, but couldn't implement it.
So, i wanted a way to implement it on the web app, even a simple gist with a bit of code on using ms cognitive services (i did read pages of the documentation, but it didnt help much), or doing it by python will be helpful.
The documentation at https://learn.microsoft.com/en-us/azure/cognitive-services/speaker-recognition/home will be helpful. Note that there are clickthrough links to the API reference. It explains the high-level process (use “enrollment” to train).
We have speaker identification, which is distinguishing who is speaking from a group of known voices that you train with. You need to provide labelled data (meaning examples of a known speaker talking): see https://westus.dev.cognitive.microsoft.com/docs/services/563309b6778daf02acc0a508/operations/5645c3271984551c84ec6797.
or
Please follow the below link speech SDK samples.
https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/
You can use batch transcription api and enable diarization.

As #Ram pointed out that we can use the Microsoft Cognitive Services, we used the same to implement it.
First, we needed an API key from Microsoft for the Cognitive Speech Service (they give a 2 keys, and an endpoint for 7 days in a free trial, without any card, and another free version for a year maybe, with card details)
Get the API keys here : https://azure.microsoft.com/en-in/try/cognitive-services/?unauthorized=1
Then, i went through the documentation of Microsoft, but couldn't really be helped by it.
What helped was this : https://github.com/rposbo/speaker-recognition-api
I went through all files, and the 'needed' part was mainly in the speech-recognition-api-demo-core.js and the demo.html
First understand what it's really doing, then only you can implement it on your page.
That actually concludes the answer, since that's how it 'can' be implemented using Javascript.
Extra - https://github.com/AdityaGupta150/ProtoMain - We have used only the needed part of Robin posbo's code (you won't be able to just copy paste, first understand it), and implemented it, you can see that in templates/verification.html
I don't know much about databases, I've been asking a few questions about them lately to get a better understanding but I'm still a bit confused about what does and doesn't need one.
I'm making a simple application using HTML/CSS/JavaScript, it has a few quizzes and "tutorials" targeted towards children. I don't want the next tutorial/quiz to be unlocked until the previous one is completed.
So for that would I need a database so that it "saves" when one is completed? I don't need to save scores or anything like that, they just get to move on once they get a passing score.
Any other requirements such as saving to a profile or needing to persist between sessions (e.g. changing of device)?
Browsers have localStorage APIs now which allow you to save a lot of the data (and keep it for a set duration of time). There are also good'ol'fashioned cookies which allow you save pieces of information as well.
Keep in mind that both of the above mandate the user use the same browser and allow these mechanisms. Obviously using "private"/"incognito" browsing would also affect saving status.
It's up to what you feel the requirements are.
EDIT Just saw your mention of a mobile app. If you're planning on allowing the experience to transcend devices, you'll need a database. otherwise, you'll be relying heavily on if they use cross-device sync (like Chrome and Firefox do with bookmarks, passwords, etc.)
If you don't mind that people can do a "view source" on the webpage or use every browsers' developer tools to find out the answers or move on to the next tutorial or quiz, then you can use cookies to store the user's status. Or you can use the preferable Web Storage API.
You might want to look at Firebase. Using just simple JavaScript on the web browser, you can have users with logins (or just allow them to login via Facebook or other services) very easily. And then you can store and retrieve data very easily as well, like quizzes, tutorials and results. This way nobody can see the answers even if they're adept at analyzing the webpage.
When you don't use database, before any check, you have to load all data in your static page.
So My sloution: store students situation in a cookie. On each page check cookie status and then use Jquery remove() to remove (Client-side) those parts of page that he/she can not access.
EDIT
This wont work when JavaScript is disabled.
There seems to be a lot of ideas but no clarifying on the database subject.
TL;DR is: No.
Now for the specifics. A database is nothing more than a way to store information. While traditional "SQL" databases (it is pronounced "Sequel" as in "My Sequel" for MySQL) have concepts of tables, where you define columns with items to store and saves each row with its value, much like an Excel file, some databases like Redis store key-value pairs and others lide MongoDB store JavaScript Objects.
You can store information in the source code (As Variables possibly) or in a file. A database is a way to organize that information.
With that said, in your case, you probably need a backend or an API. An API is basically a means of communication with a server through AJAX (JavaScript in the browser asks for stuff). That would be your way to retrieve information from the server as needed, so that users wouldn't see the answers before they answer.
With that out of the way, there are some options. FireBase (As noted on other answer) and AppBase are easy ways to integrate this concept with little effort. But they tie you and your information to their system, and they are mostly targeting more resource intensive apps.
Since you are using JS and seem to be enjoying your learning experience, I would suggest you consider suing NodeJS and defining the data as either a JSON file or a variable in JS. You keep working on your problem but add options and get to learn some stuff.
If you decide to integrate a database and possibly do some neat stuff, you have most of the groundwork done already.
If NodeJS picks your interest, Mean.IO and KrakenJS are, in my opinion, the best places to start, though they may both seem overkill in your specific case.
Do consider though: A database is just a small possible piece in a puzzle, and it's mostly a horrible way to name some of the software that tries to organize your information. Consider first if you need to organize information, and what and how do you need to organize, then start thinking if databases are the best way to organize it.
So let's say I have a website which doesn't require login but I want to be able to track the user's activity based on what they click on my website, and display data accordingly. For example, if they keep looking at children's books to buy, I would recommend similar children's books. Is this possible in javascript?
The only solution I can come up with is cookies, is there a more efficient way?
Thank you.
I hope this is an acceptable question to post on here, as it is not code related
You could use HTML local or session storage. These are both easier to use than cookies.
You can also use Modernizr for browsers that do not support HTML5.
html5 websockets might be of help.
Got a question for you ... I'm currently working on a simple groupchat functionality for a webpage. It will only be available for groups so there's no need for the users to specify a nickname or anything like that ... the nicknames will already be known to the system since the users have to be already logged in.
Anyways it should just be a simple chat room for the whole group - no 1on1 private chats!
Question is: Would you consider it a good idea to have a look into Ajax Push (like here for example) or is this overkill for a simple group chat ... don't expect toooo many people to use it that much so maybe push is overkill and longpulling via jquery would be better (in that case - do you know of any really good tutorial for a longpulling chat-functionality?)?
Any tipps or other input is greatly appreciated! :)
best regards

Pull would be easier, but would be a bigger load on the server and obviously not quite as real-time. For a good chat experience, push is definitely better. You may be limited on your ability to implement it, though, depending on what technologies you have on your server and how much control you have over it. I've implemented a push (Comet) system a few times, and it's definitely doable. It's really up to you. It sounds like you've got an okay handle on the things you should be considering (number of users, difficulty in implementing, etc). The more users you have, the better it's going to be to be using push because it'll take a lot of strain off the server, and it'll improve the interaction in the room.
Another thing to consider is what browsers you want to support. Supporting IE with push can be more difficult than supporting other browsers, but it's definitely doable (I've supported as far back as IE6 before).
Finally, if you only care about supporting modern browsers, you may want to consider using web sockets instead, as that would be both easier than push and better performing.
I will be developing a web application with Google App Engine that will use Facebook Connect as the only means of registering / logging in. The web app will be written in Python. I need to know their name, profile pic, how many friends the user has, as well as their age and also possibly location, relationship status, work info, etc. (although those are mostly optional besides name, pic, age and friend count).
There seem to be a number of libraries that can do the task. There is the official Facebook Javascript SDK, minifb, and pyfacebook to name a few.
How do you think I should go about this task? Which libraries should I use, and what are the pros / cons?
Also to be considered is how well documented the code is and how widely it is used. If you can provide links to relevant example code / documentation, that would be greatly appreciated.
Facebook python-sdk has an example application to use Facebook connect with Google App Engine. I guess, you are looking for the same.
This should be a comment for the answer which suggests using the Facebook python-sdk.
Note that at github it says
This SDK is deprecated. It does not support the new cookie format that
we rolled out as part of the OAuth Migration. In short, it doesn't
work.
I've had success with the facebook-sdk project, which I believe is a fork of Facebook's original (and now dead) python-sdk project noted above. However you may also wish to check out EngineAuth.
Why don't you check out this similar question asked by another StackOverflow user:
Simple Facebook Connect in Google App Engine (Python)
There are some links provided here that sound exactly like what you're looking for.
For all specified detail you need to go with respective permission from users and then you can extract all specific information you needed.
You can go by either Graph Api or Javascript Api:
But with javascript you need to use many ajax request through your application where graph api only need access_token once for particular instance and also independent of client action.
Graph API also helps you in preventing use of other framework like pyfacebook, minifb, etc.
Apart from pros and cons you can also look some example code for both javascript and graph api
Hope this information will be useful to you.
