By using a method called “Data URI Scheme”, images can be directly embedded in HTML files. An image is converted to data uring base64 encoding, the data is appended in the page, which works as the image itself.
The data URI scheme is a URI scheme (Uniform Resource Identifier scheme) that provides a way to include data in-line in web pages as if they were external resources.
When we started building dynamic elements with jQuery, the issue of registering events to the dom used to be a hassle. Then .live() came to rescue where irrespective of the when the element is added to the DOM, the events associated could be triggered dynamically.
But now live() is deprecated and jQuery recommends using .on(). On() works fine everywhere and we do not even realize or even bother to find out what is the benefit of using .on() over .live() or why has jQuery given up on the beautiful sounding “live” function.
Lately, any web savvy is confounded by a slew of accounts to maintain and passwords to remember. The hassle of remembering multiple email accounts to some extent has been solved by the concept ot Open IDs. GRAVATAR addresses another such issue of managing your profile picture across a number of accounts. Be it from the perspective of maintainability or from your "online brand consistency", reusing profile picture from a single place is a cool idea. So Gravatar offers such service where one can upload an "avatar" mapped with a certain email address which can be later reused into a number of sites.
As a developer, even the thought of talking in front of a crowd could be intimidating, especially if you are the kind of developer with the “weird” habit of talking to yourself; well you may have this thing coz computers don’t talk unless there are some free people on the other side of the “internet”.
I teach ASP.NET and Web Tech in a college for BSCIT students. It is more like training than teaching because it is all about knowing “how to do it” instead of “what it is”. Moreover, with programming courses like asp.net, the whole idea of teaching could boil down to simple demonstrations
I was working on a small project where I had to load .ascx controls using jquery. I used string writer to load the jquery html into my parent control on click.
Now I had registered event handlers for the loaded control using .live. When I loaded the control for the first time, it was fine. But after that everytime I loaded the control, the event associated excecuted multiple times which was not supposed to happen. It looks like every time the control is loaded, the live event is registered again resulting multiple events to execute.
Well, it is most of the times we are always craving for a better bandwidth, but there are times when we want to work on minimum bandwidth. This happens often in testing scenarios. Recenty I was working on a small project which required the use of ajax indicator. As I was working on my localhost, I couldn’t even see properly how the ajax indicator looked like. So I searched for a way to simulate the real “internet” scenario i.e. simulating low bandwidth in my localhost and I found SpeedLimiter quite handy in doing so.
The web is so much stuffed with CMSes these days, good CMSes and bad CMSes ,Open Source CMSes and not-open source CMSes. A normal computer user surfing general internet for news and stuffs is inadvertently clicking those CMS powered sites. CMSes mostly are purposed to build websites. With a lot of plug and play mechanisms ranging from functional plugins to design templates (installable and switchable), CMSes do make the web site development and “maintenance” quick and cheap(less expensive).
