I have learned basics of ExtJS and developed some web apps using ExtJS. Now I have to develop web desktop using ExtJS (like desktop app which is present in examples folder) but I am not able to find any documentation or tutorial or book about how to develop it.
Does anyone knows how to develop web desktop application using ExtJS 4? Where can I get any tutorial/ book/ video about developing web desktop?
I doubt you'll find a book or tutorial dedicated to exactly what you're looking for, but you can put together enough resources across the internet to do the trick.
A Google search of "extjs 4 cookbook" turned up a book called "Ext JS 4 Web Application Development Cookbook" that seems to have plenty of information. However, it seems very new and I personally haven't read it, so I can't vouch for it. But it's there.
Other than that, Sencha's own documentation site will have most of what you need. The series of articles on App Architecture may be of some use if you're planning to take the MVC approach, as will the articles on components and layouts.
That will cover the basics, but there's no real definitive guide to making a web desktop app that I'm aware of. It all depends on what your requirements are, how much time you have available, etc. If you're looking for help with a specific component (like creating a Windows-style file browser system) then you'll probably have better luck asking more narrow questions.
You can just use default Web Desktop Sample provided by Sencha and modify it a little bit.
I am also interested in, I did what I advice you, so you can look what I have received now:

Hmmm, these free hosting providers use lot of ads if your site becomes clickable.
I created another mirror, there should be no ads: http://www.julfysoft.16mb.com/index.html
but it can take a while to load it...
We inspired from the desktop sample and we build a full functional web app using Extj 6.7 along with Unigui Framework (Delphi), and the result is awsome:
Just implementing the idea step by step.

Flutter is amazing but when your architecture needs the backend to be separate from the app. What are some options that will be good to consider?
Some options that I have looked at are: Node.js, Java, Dart & Firebase (Unsure whether Firebase can meet all the requirements as a sole backend of production-level apps)
We need to develop a full-fledged REST API which will be used in Production with the Flutter app.
Thank you
It really depends how much time you have, and you're willing to spend on your backend. If you're rushed and want an MVP as soon as possible I would suggest FireBase, It provide great a simple but efficient database and more tools like instant messaging, built-in push.
If you have more time and want to build you're own features, Node.js with Express and Mongodb would be perfect.
Have you looked into .NET Core Web Api? I have used on some projects on college together with MongoDb and works really well, I never try it with Flutter, but as a Api it works fine.
Edit: I just found this question, maybe it can help you Combining Flutter frontend with .NET Core backend for Android and iOS

I want to be able to contribute to Google Translate on my native language (Sinhala).
Although there is an online portal (http://translate.google.com/community/) where we can contribute to the translator by translating new phrases or validating existing translations, I would like to create my own, lightweight portal (maybe an Android app) for the contribution service. However, I was unable to find any public API for the translate contribution platform, despite a thorough Google search and a full search through the Google Translator Toolkit API forum (https://productforums.google.com/forum/m/#!categories/translator-toolkit-api) (which seems to have been closed down since the end of 2012).
Currently my best hope is to mimic the request-response sequence followed by the online portal itself. For example, the following request is used by the online portal to fetch a question list for manual translation:
GET http://translate.google.com/community/question_list?sl=en&tl=si&client=t
However, it requires that all the related cookies are properly initialized and passed with the request, which would probably not be easy to mimic in a non-browser environment (such as an Android app). Hence I believe there's a better approach (maybe a yet undocumented API?) somewhere out there.
Does anyone know of any API for accessing this translation contribution feature?
Thanks in advance.
Please note: I am NOT looking for a way to improve Google Translate itself, but for contributing to the actual translation content as described under "How can I help?" in the Google Translate Community FAQ (https://docs.google.com/document/d/1dwS4CZzgZwmvoB9pAx4A6Yytmv7itk_XE968RMiqpMY/pub#h.e1ahmpftpdum).
P.S. I was initially planning to post this question on the Web Apps Stack Exchange, but after reading this post I decided to first try it here.
I'm one of the engineers behind Translate Community and I'm really excited that you want to see it on more platforms. We're currently under active development of the site and making it more accessible on mobile platforms without having to create dedicated native apps.
For the time being, we don't anticipate releasing a public API as the platform is under active development. Until we do release a public API, please don't use any http commands you find to create a separate app. Instead, just let us know how we can make the app a better experience for you and we'll work on making it better.
Thanks!

Just wondering. I'm looking to build a small web application with a single page. It will essentially be a video chat page so I'm looking for an API I can use or any other solutions?
This would be run on a LAMP stack.
A SO search reveals lots of similar questions which are worth checking/contributing to.
It depends if you want something free or are prepared to pay but some things that come up are (mind I havent used any of these myself):

Some MS libraries are mentioned here: Developing a Video Chat Application with high quality video streaming
Apple had promised to open up FaceTime but so far nothing has happened
To get up and running quickly it seems tokbox would be most suitable.
Look into WebRTC, it's a new technology by Google and doesn't require any plugins! It's still under development but the code is available and working at the moment!
I know it's a bit of advert, but you could try to look into http://www.addlive.com. We offer comprehensive set of APIs allowing you to build RTC apps on the web (JS bindings on top of a plug-in and native WebRTC if available) and native mobile and dekstop SDKs.
Vidyo.io can help with this. (Full disclosure: I work for Vidyo.) It provides a simple JavaScript API that supports WebRTC capable browsers and a plug-in for Safari and IE. We also have sample apps on our github page https://github.com/vidyo to help you create a page simile to what you're looking for.

How did they implement text to speech (TTS)? Is there an open, free API for TTS synthesis? I know about Google Translate, but the license is not clear to me (another issue is that they block a request if it contains a referrer). Any idea?
Majdron,
I'm a lead developer at Quizlet. We're using a combination of our own technology and licensing/purchasing TTS software from several different companies.
There are some open source TTS engines/voices:
http://www.cstr.ed.ac.uk/projects/festival/
http://www.babelfish.org/tts-free.htm
http://espeak.sourceforge.net/
http://freetts.sourceforge.net/docs/index.php
http://mary.dfki.de/
Good luck!
The voices sound exactly the same as http://www.neospeech.com. Also, their list of languages match exactly.
It's not free, you have to license it.
Google has just introduced browser-based access to its speech engine through HTML5.
http://slides.html5rocks.com/#speech-input
To get this page to work, I launched the Chromium browser as follows in Ubuntu:
$ chromium-browser --enable-speech-input
I'm not sure if this works in other operating systems.
Another interesting project is WAMI from MIT:
http://wami.csail.mit.edu
I don't know which specific engine Quizlet are using, but assuming they are using a free service then it might be TTS-API (http://tts-api.com/) which was recently featured on Hacker News.
From what I know is the only "free-to-use" TTS web-API out there. Please comment below if I'm wrong - I'd love to find similar free services. There are a lot of pay only services out there but very very few truly free ones.
Since finding out about TTS-API on HN I've successfully used it in a recent app project. Since the TTS is only a HTTP fetch away I was able to quickly integrate it in both the iOS and Android versions of my app. The service appears to be very quick, so no complaints so far :-)
Nobody gave the right answer. They have their own TTS engine that is connected to a single file located at http://quizlet.com/tts/en.mp3 the file takes arguments with it so the url http://quizlet.com/tts/en.mp3?v=14&b=QXJlYSBvZiBwYXJhbGxlbG9ncmFt&s=m5dx52Q. says "Area of parallelogram" thanks the first base64 string labeled b. I have not discovered what v or s are used for but I know they are essential for making the file speak. I will do more research and get back to this answer.
jj b is correct. The core engine of Quizlet's speech features is Neospeech, and uses Neospeech's VTML (VoiceText [TM] Markup Language) exactly, as far as I can tell.

OSX question, not iOS.
I've been searching for a framework to get easy access to the full (or at least the most important functions)of the V3 API Google Maps within a WebView.
From what I've read so far it should be technically possible.
https://developer.apple.com/library/archive/documentation/AppleApplications/Conceptual/SafariJSProgTopics/ObjCFromJavaScript.html
I found a nice little simple tutorial on V2 which works great.
http://www.josephcrawford.com/macdev-articles/google-maps-in-a-cocoa-application/
Now before I start re-inventing the wheel and coding everything from scratch (callbacks from map-pins etc.). Is there nothing open source or similar around?
I'm surprised I could not find much on that subject since having a MapView in Cocoa OSX sounds like something many people would find useful theses days.
Thanks for any pointer to an open source project, tutorial or what may be floating around which I could not find.
meanwhile I found this open source project which seems useful to learn how to do it:
https://github.com/nst/CocoaSlideShow
Found this pretty nice Wrapper which does 100% the same like the iOS MKMapKit:
https://github.com/Oomph/MacMapKit
Have you checked out Google Mapki? It documents unofficial Google Maps API features. There is an Cocoa Touch example on Kadir Pekel's blog here. Though it might be difficult to adopt the example to Cocoa since it makes use of MKMapView.
Try here programmable web i could not see what you want but there are at least two objective-c wrappers for other popular api's, not google maps tho, and so it might be a starting point.
I am not sure you need a framework to do this. Did you have a look at the link below?
http://code.google.com/intl/fr-FR/apis/maps/articles/tutorial-iphone.html
Then all you need is generate the HTML from your code and load it with UIWebView's loadRequest.
That's what i did in my iPhone project, worked like a charm.
