Any Idea on on how does the HTML 5 Terminal work? - html

I happend to stumble upon this site
http://www.htmlfivewow.com/demos/terminal/terminal.html
It is simply amazing. I was just wondering on how is the terminal being emulated in the browser ? Can we embed the terminal in the browser and use it normally ? If so how?
i found this link which kinda enlightens the architecture http://www.htmlfivewow.com/slide33
But one thing aint clear what exactly is CRX-LEss Web app ? its completly new term , i havent herd of it before ( googling dint quite help me )

The actual presentation for the demos is from the Google I/O conference, and the talk was called HTML5: The Wow and the How. If you watch the video, they go over everything that's implemented in the terminal demo:

It's very cool stuff.

A great thing about the web is that on any page you can View Source. Give it a shot. The source is well-structured and though it could be better-commented it's pretty straightforward. Even if you don't understand it in its entirety it will give you a place to start searching for the techniques used.
With JavaScript, the DOM, and <canvas> (which, I should mention, isn't used in this instance) just about anything can be created, from terminal emulators to Nintendo emulators.

A CRX-Less web app is an unzipped Chrome extension and points to the manifest.json file for the extension. It is an experimental feature and must be enabled in the chrome:flags page. https://developers.google.com/chrome/apps/docs/no_crx explains how the process works.

Web browser interface using HTML/CSS/JS?

I’m building a simple browser, and I’d like to code most of it using HTML/JS/CSS. I cannot use iframes to display pages, due to frame-busting. What are my options?
The browser is not meant to be production-quality, but as a proof-of-concept for my thesis, similar to this interactive mockup. The main features it will need to support are:
Loading any page without frame-busting (even google.com),
Detecting when a link is clicked and opening it in a new frame, with the original one remaining intact.
I intend to write this using Web technologies, but it’s OK if it needs to be wrapped up in a small amount of something else, e.g., to turn it into an Android app. However, if it’s possible, it would be best if I could load the app as a web page. Finally, it is also preferable to be able to run the app on an Android device, but it’s OK if it only works on a desktop.
In researching this question, I came across a few options:
<iframe>. Google.com doesn't load at all in an iframe. I tried using the sandbox attribute, but it still didn’t load. Is there a way around this (for any page)?
Mozilla’s Browser API. This API was supposed to allow you to use the mozbrowser attribute in an iframe when building FirefoxOS apps. I suspect there’s no longer any way to access it. I couldn’t get the sample browser app loaded, and it seems that mozbrowser is not supported in WebExtensions. Did I miss something? Is there a way to make this work?
<webview> in a Chrome app. This is the only option that worked so far. I was able to download and install the sample browser app in Chrome. The one downside is that it seems to be Chrome-only (and I would prefer cross-platform or Firefox, all else being equal). Are there any issues with this option? Any way to make it run without Chrome?
Electron app with <webview>. While the setup here is more complicated than the previous option, it seems like the code would be very similar (there’s even a similar sample browser app). Are there any advantages/disadvantages to this option over the previous?
So, are there ways to make options 1 or 2 work? Are there perhaps other options?
HTML/CSS is a "language" translated by the browser into pages. You cannot code a browser in HTML. The easiest solution is to code it in C#.
I'm not sure if this is a good solution, but you can try Electron (nodeJS). You will only need to use JS/CSS/HTML.

Is it possible to detect a HTML video playing on a browser?

I want to know if a html video is being displayed on a browser, from outside said browser, ideally without any plugins or such.
Motivation - I am trying to add this feature to Caffeine which is a Linux utility which disables the OS screensaver if, say, you are watching a movie.
The flash support was done I believe by detecting the presence of particular files or folders created by the plugin.
Ideally I would like 1 solution, but if I get 2 solutions for Firefox and Chrome, that's good enough.
p.s. Ultimately this would involve python code, but I am not sure if that is sufficient to make this question on-topic, or if this belongs on Superuser or Unix&Linux
This reminds me of something a web browser I was building in VB .Net which needed to detect if there where web pages that had tags like <a href="tel: or <a href="smsI know you said you didn't want a plugin but I would think you could easily right a browser plugin for for just this. In fact not exactly what your looking for but theirs a script monkey script called Hangouts Unlimited which prevents you from getting annoying messages asking if your still awake while in a G+ hangout. I don't know much about python but I would recomennd trying to identify the elements of the tags and when ever it finds such tags to disable the screen saver. Obviously the hangouts unlimited doesn't affect the web browser and that is most likely why you prefer not to have a browser plugin because you need to access system files outside of the browser. But I hope this helps a bit.

Anyone familiar with Vimeo? Trouble with js_onLoad, broken?

Hi all I was trying to get the vimeo "swfobject.html" example from git hub to work, but it simply doesn't work # github.com/vimeo/vimeo-api-examples/blob/master/moogaloop-api/javascript/swfobject.html
I debugged a bit, and realized it doesn't even enter the "js_onLoad" function. Does anyone know if this github code dated or is js_onLoad deprecated? I'm just trying to do a simple example of displaying the alert "hi" after the player is loaded, but I can't even get that far.
My very simple sample code is here: http://pastie.org/1110855. Does anyone see a problem?
Any fellow stackoverflowers versed in vimeo JS API? Cheers
I feel your pain. There's a bunch of inconsistent information about the vimeo API out there. But there are still parts that work. Check out the API Playground which works and demonstrates clearly how to do all sorts of useful things. The source code is on github. You can take apart the playground.html file and just leave in the parts that you need.
Important caveat about the playground.html file -- it doesn't work (for me) when running off a file:/// URL. It has to be coming off an http server to function at all. HTH.
I consider myself a bit of an expert on the Vimeo JS API. Their documentation and demo's are very poor, so I put together this little demo that I think it much easier to follow. It users jQuery and the iFrame embed method, but hopefully it helps:
http://labs.funkhausdesign.com/examples/vimeo/froogaloop2-api-basics.html
It shows how to listen for an event and fire a method.
After several experiments, it seems that events are only fired with the HTML5 version of the embed, not with the Flash version.
As the Universal Embed code (iframe) automatically selects the technology, I believe that the best way to go is to avoid using it and make your own embed.

Hiding Chrome bookmark text via extension

I'm trying to get a start in programming by writing a Chrome extension similar to the Smart Bookmarks Bar extension for Firefox. Java seems straightforward enough, and I can probably figure out the specifics of building an extension but I can't find out what commands I need to change the rendering of the bookmarks.
1)Does anyone know where I could find the relevant documentation?
2)Does anyone know of extensions that interact with bookmark rendering I could take a look at the source code of?
Everything you can do with the bookmarks is listed in the API:
http://code.google.com/chrome/extensions/dev/bookmarks.html
(and as someone said here on SO: java is related to javascript as a car is related to a carpet :] )

Drag and Drop from Flash/Flex to HTML and Vice-Versa

Is there a library simplifying the process of dragging and dropping between the Flash/Flex environment and the surrounding browser?
I've done some research on the process, and so far the closest thing that I have found is from HTML to Flash in a Floorplanning application. I have yet to find a demo going in the other direction however.
Is there a simpler way to do this now?
I didn't even think it was possible at first until I looked at that link, and I agree with their description that it will be very difficult to get working on all browsers / OS's.
