Ways to make a voice call from a web page? - html

My app will look like this: two people enter a chat or something else in a page and have a skype name or Gtalk. Is it possible to make an anchor to call a voice client from the web page? Is there a flash fallback for this?
I know the skype: prefix that actually doesn't work for me in Ubuntu, but should work for Windows users.
I primarily target PCs & macs, but supporting mobile platforms with a solution will be nice.
For Downvoters: any comments why you do this? Please bother to explain me the obvious thing that I don't know and make this question.

Your question is much too complex. Instead of answering it, which would take several pages, the person might as well write the application him/herself and sell it.
You have to divide your problem in tiny bits, and have a question for each one.
You could at least start with looking at gTalk API and Skype API to see what you need yourself.

Extension like Picture-in-Picture (by Google) but for any part of the browser and not just videos?

Hiyah!
I'm sorry for this strange post, just need help articulating my thoughts into something practical. I really could use an extension to basically select any part of the browser window and use it as a floating window (always on top of other windows).
It'd be awesome if something like this existed and I'd love a name in that case! If not, maybe any of you know of similar open source projects that I could take a look at? I'd try to write my own extension if there's nothing like that, so basically could use any keywords to simplify my research. I've been learning full stack web dev for a few months now, so I think it's in realm of possibilities for me.
Thanks for your time!

Windows Phone 8 Picture editing

I work with Windows Phone 8. I want to be able to take a button, tap it and load a picture from the phone into a window to edit it. Can someone please direct me to where I can find info on this or tutorials? I'm not asking someone to do this for me, just help on how to do it myself.
Welcome to StackOverflow! Your question is a bit too broad for StackOverflow, next time please try to focus on a smaller problem. "Windows Phone 8 Picture Editing" is too general.
But I know it is a hard topic to start on, and there are not many resources about it (especially compared to iOS). If you are not good with Windows Phone app development, I'd first recommend some easier examples.
Anyway, here is a simple app that demonstrates setting an image onto a view from a local file: http://developer.nokia.com/Community/Wiki/Loading_local_image_file_on_Tap_events_in_Windows_Phone
If you want to choose an existing photo, it is even easier. You can
follow the instructions at this link:
http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394019%28v=vs.105%29.aspx
To take a photo, you can use the camera capture task, which is very
similar to the photo picker. Here is how to use it:
http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394006%28v=vs.105%29.aspx
If you need a more advanced/custom camera, you can implement your own
camera. A relatively simpler example is here:
http://msdn.microsoft.com/en-us/library/windowsphone/develop/microsoft.devices.photocamera%28v=vs.105%29.aspx
If you trust yourself, a much advanced example is here (I also
followed the same tutorial for creating an advanced photo filtering
app):
If that is too hard, you should definitely take a look at the Nokia
Imaging SDK for Windows Phone 8. It has many built-in filters that
anyone who is interested in making a photo editing app would like:
http://developer.nokia.com/Develop/Windows_Phone/nokia_apis/imaging.xhtml
If you still need more, or if you want something more lightweight and
smaller than Nokia Imaging SDK, just look at
WriteableBitmapExtensions that enables you to perform simple
operations: http://writeablebitmapex.codeplex.com/
When you are done with the actual image editing/programming, you should consider the user experience and total integration in more general.
To extend the phone to make your app a fully-featured editing app, head over here: http://code.msdn.microsoft.com/wpapps/Photo-Extensibility-Sample-db289044
This also explains the topic on extending the editing section in greater detail: http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj662932%28v=vs.105%29.aspx
I could write hundreds of lines of code directly here, but it wouldn't have meant anything. I hope these links help you (and many others) as a starting point for image editing on Windows Phone. But remember to ask more specific questions next time :)

Mobile html shortcuts

I'd like to know what are the shortcuts (href codes) that bring up different functionalities on different devices.
e.g.
mailto: (opens the mail clients on a desktop/mobile)
tel: brings up the "call" option on a phone
What are the others ? Is there an "sms:", etc ?
I am sure that these links depend on the system which they are ran on, and so not all will be implemented on all devices.
However, I found some a link at least for blackberry devices which you will find useful.
Here is a fairly full list:
http://beradrian.wordpress.com/2010/01/15/special-links/
AND
http://docs.blackberry.com/en/developers/deliverables/11844/Feature_link_behaviour_438487_11.jsp
This shows WTAI, tel, dc, cti, mailto, pin as link types.
I know there is also "geo" as one.
I am fairly sure that applications can be used to handle different types of link, so this list is in now way complete.
I hope this helps.
If you're talking about Android I don't think there's no comprehensive list because each app is capable of adding it's own. Some are certainly more popular than others though.
There are quite few tricks which are exclusive to mobiles. I actually just published an article yesterday on the very same topic where you can find a list of protocols, tags you can use exclusively for mobile.

technical comparison between the differences in html of jquery mobile and webapp-net

I am trying to build an application for smart phone devices. I have searched a lot over the web and I found some good toolkits, These are the toolkits I am considering to work with. Jquery Mobile and webapp-net.
The only problem is I need to kknow about the technical differences in html of these two toolkits. so if you please help me.
BTW this is my second account here, with my previous account i cant not ask any questions here, I want to know what are the reasons to close someones account, I am only here because I need help, and I dont want to waste anyones time. I come here to ask a question and then, some one comes and just does something to my account and I dont even know why they do that. So what is the point of this website if you close some ones account???
When consider Jquery Mobile and webapp-net, JM is elder and is coming from rich and stable family, that never ment webapp is poor, but you have much recourses and help from the net if u start ur work with JM.

Can the site built entirely in Flash be still SEO-friendly and visible in search engines? [closed]

My website will be basically selling services; will my SEO ranking still be affected if I embed the Flash site in a blank html page? I am at that critical point where I am ready to upload the site but I am just having second thoughts about the ease of doing business with Flash.
Ignoring the SEO implications of an all-Flash site, unless you're building games, or I have an extremely strong desire to buy what you're selling, I will turn back immediately if I find a website built entirely out of Flash.
Nothing against your programming skill; I just have rarely seen such a site give me what I want. The name is often apropos.
Search engine crawlers can't crawl flash sites, so your SEO rankings will be based off the non-flash part (the blank html page). Personally, I also don't really like the user experience of a flash-only site.
Google and Yahoo! have added flash crawling functionality to their engines recently.
http://www.adobe.com/devnet/flashplayer/articles/swf_searchability.html
From a SEO perspective you're fine on that front. Still..your page will need a DOC TYPE, Page Title, etc to remain SEO compliant.
IF your target market is users browsing your site from a laptop or desktop you should be fine. You may want to include a flash-free option for users accessing your site on a mobile phone or with javascript/flash disabled.
For example, You can run a browser sniffer to redirect any user agents accessing the page on Safari via an iPhone OS.
Other than that Flash does offer some nice flair to a site. If you can give alternatives to users that don't like the application then I say do it.
It can certainly be done well. I've seen some pretty cool Flash-powered stuff being run by some pretty big-name companies, do a search for HP's Photosmart page for instance.
Look: there's a lot of information out there about Flash and SEO, and much of it is out of date. Google rolled out "official" flash support about a year ago, and they've been refining it ever since. Google will index your Flash site, but exactly what gets indexed is a bit of a black box so it always helps to have HTML alt-copy.
Never, ever build a full-flash website without using SWFObject for embeds and always try to use SWFAddress to enable Flash Deep-linking. There are ways to make this work and work well - a lot of people don't know that and have a deep-seated hatred of all things Flash because they were irritated by Splash pages in 2002. There's nothing to be done about them.
But if you want to use Flash, go for it - just do a lot of homework and test your work.
Whether or not it's business suicide depends on how much of your revenue is dependent on getting referrals from search engines. Your search engine ranking will certainly be affected if you have an HTML page in which you simply embed some flash.
Could you implement an alternative more static site, by scraping the main content from your flash?
all web applications should be made from the point of view of accessibility, no matter what the scripting language used at the time. If you use a nice script like SWFObject then you can populate your page with "alternative content" to the flash page which the search engines will crawl. this will also allow any browser that doesnt have flash to have a look at the website, even if you dont make the whole thing as "pretty" in HTML.
two birds as they say.
I don't know whether you've considered this or not, or whether it applies to your circumstances, but you might lose out on business from the visually impaired. Unless I'm mistaken, I don't think there are any screen readers that operate on Flash.
I think it depends on what kind of business we are talking about.
For most, I would say don't do it!
But there are ome kinds of sites where I think it is appropriate, if done very well. For example if you are in the business of art or design, or are showcasing a product/service where art or design is key.
As an example:
Volkswagon's GTI Project (a large part of what cars are about is design)
Flash has fallen out of favour the last few years with a lot of people. Initially it was because search engines didn't crawl it but these days it's mainly because 'flashy' effects can be done with javascript engines like jquery, scriptaculous or mootools.
Having said that I can tell you that nearly every business customer I go to still wants flash on their site and most casual web users don't give two hoots what a site is built like as long as it works, is fast (something kinda tricky to do with flash) and is what they want to look at.
I say go for it and see how the site does! I'm sure if you use analytics for a few weeks you will know whether your site is doing well or not.
Best of luck with it :)
For some reason Motorola made their new Droid site all in Flash.
This is a good article about how dreadful it is, and the drawbacks:
newmedia article
There are a ton of good reasons to use Flash sparingly. It's good for what it does well and dreadful for entire sites.
Ok so first of all, perspective, my primary domain is Flash and system architecture, I and the company that I work for at present are all about creating online 'digital experiences', engaging online content.
This is NOT applicable to selling services, e-commerce, and general information based sites, as much as it pains me to say that. There is current a massive backlash against flash due to the arrival of javascript effects and the canvas tag, I'm going to be bold here and say that anyone who thinks they can replace x years of plugin development and and media experience by giving html/javascript devs a div they can draw into are simply misguided (and you can show me all the chrome experiments you want but its still not going to be pixel bender or native 3D support).
So with that said, in this climate you've got to play to each formats strengths, you want slick, stylised SEO'd content that is accessible and concise, html with progressively enhanced javascript is a no brainer. You want a web app that people can use easily, search and build a micro-community around then googles GWT (other js frameworks are available) is the way to go. For everything in-between and beyond theres Flash.
I'm not giving Flash a kicking (it's my lively-hood after all), far from it, in fact I'm actively encouraging people to use Flash only for the kind a digital master-pieces it was made for, if you can do it in HTML, why would you do it in Flash? Sure in most cases it actually works out lighter than JS, and it's cross-browser compatible, but these are small issues that will only be ironed out in time, HTML was designed for the web, Flash was designed as a plugin.
In coming years we will see Flash on a multitude of devices with the open-screen project and the iphone-flash cross compiling, it is becoming a platform for multimedia development in general, where-as the web is becoming more service orientated platform, web apps running off searchable indexed content in the cloud. If your website is intended for the web, then make it for the web.
(Just realised that this was a bit of a rant, apologies)
If you created a web site with Flash, user will not be able to use basic browser functions and extensions such as searching, spell checking, sharing a particular page via Twitter, etc.... (And cannot access from iPhone.)
Depends on the site in question. If its just displaying marketing collateral or case-studies then a "flashy display" would be fine. Have seen couple of such websites in the past and the better ones have impressed me.
You should also consider how frequently content would change and how it impacts your design in Flash vs say design in html. The search engine ranking aspect also will matter.
You won't get any business from me.
Nothing says 'amateur' on the web like pointless Flash.
