I have been using Sinatra for sometime now and I would like to add some realtime features to my web-app by pushing the data via websockets. I have successfully used the gem 'em-websocket' on its own, but have not been able to write one ruby file that has a sinatra web server AND a web-socket server. I've tried spinning the run! or star...

I have an html5 page with a navbar. Completely scratch coded. I just recently added a doctype to the item, and now I’m getting extra space under my navbar. If I remove the doctype declaration, it goes back to normal. I have completely reset padding, margins, etc. on everything, and cut it down to the a small amount of code that illustrat...
Hi Folks, I'm wondering if there is any build-in support for the HTML5 Notification feature in Gecko browsers so far? Maybe some hidden developer thingy ? I'm aware of WebKits window.webkitNotifications which works great, so, is there a Firefox implementation ? update After searching and reading some w3c HTML5 specs, I'm maybe a litt...
OK, so I bought a 46" screen for the office yesterday, and with the imminent risk of being accused for setting up an "elaborate World Cup procrastination scheme", I'd better show my colleagues what it's meant for ;) Looking at my simple sketch, and at these great projects from which I was inspired, I would like to get some input on the ...
Hello everybody, I'm trying to develop something in the cloud incorporating video, text and images. However, any hyperlinked content that appears above or below the video is unclickable, as the video takes the focus on the iPad. This isn't a problem with Safari in general, as it works on Desktop Safari. Thankyou, BH ...
First of all I will explain how I stumbled into this behavior. Within my web application I am using some custom validation for my form fields. Within the same form I have two buttons. One to actually submit the form and the other to cancel/reset the form. Mostly I use Safari as my default browser. Now Safari 5 is out and suddenly my can...

I'm trying to load on the fly on the iPad/iPhone and notice that I cannot place a div above this. I put the overlay in the html so that it's generated on page load and not added via javascript and the video when its created is absolutely positioned below this element. This works on a PC, I'm wondering if since it was created via js th...
What's the difference between local/html5 on this page: http://code.google.com/p/jquery-jstore/wiki/DefaultEngines I was under the impression that I could use localstorage on Chrome, but looks like that's not the case? Some elucidation would be greatly appreciated. Thanks. ...
I have a very large html canvas element covering a solid background. I would assume that a lot of cpu could be saved when scrolling/panning if the browser did not blend the canvas to elements behind it (in this case, a solid color). Is it possible to remove the canvas alpha channel? Should this be left up to browsers to detect and optim...

Without any extension library, is it possible to have multiple layers in the same canvas element? So if I do a clearRect on the top layer, it will not erase the bottom one? Thanks. ...
I'm familiar with the way html & css work together. Recently I was previewing some html5 content demo'd by apple and saw they used a html5/css/javascript. I'm at the point where I need to know whether or not javascript is a must-learn; or if I can find similar workarounds with CSS3 & HTML5. Edited to clarify intentions: My aim is to ...
For a little project about XML I try to use HTML5 as it has SVG and WAI-ARIA Support. I also want to use a XSL stylesheet for my document. But I can't get a valid HTML5 document with a nested SVG. Here are some version I tested so far: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999...

I'm looking to recreate an effect similiar to the popular science app. Basically have one big background image and then have HTML/CSS layer on top of that. When the user scrolls the content, then background-position of the image should remain in place, and not scroll. Obviously in a 'regular' browser I would use background-attachment:fi...
I read some time ago about the possibility to use media stream from a USB or rs232 device with the tag such as a webcam with HTML5?. Is there a web browser that supports this right now?. (nighty builds of chrome, webkit...) Thanks. ...
Hi - Is it possible to drag an HTML 5 object, e.g. an <a draggable="true">, into a Silverlight 4 control and accept it? We've attempted to build a simple prototype using an HTML 5 example and a trivial Silverlight control but the cursor changes to the no-entry sign whenever we hover over the Silverlight control. We do, however, get drag...
