You can access any individual public users timeline or their favorites in RSS, ATOM, XML and JSON formats:https://twitter.com/statuses/user_timeline/<username>.rsshttps://twitter.com/favorites/<username>.rssReplace the username in...

These days all popular browsers - IE, Firefox, Chrome, Opera, Safari, come with Developer Tools that help web developers debug HTML, JavaScript & CSS issues & build better web pages.It's probably the Netscape browser that first started helping developers with the Error Console option that would specify on which line a script error occurred & the possible cause. Firefox inherited that option while Firebug, the Firefox add-on, extended debugging facilities within Firefox to a different level. Firebug's feature-set is so comprehensive,...

Key takeaways from Chapter 13: Using Iframes Sparingly of "Even Faster Websites", a guide for performance vigilantes -Relative URLs inside the iframe are resolved relative to the iframe’s base URI, not the parent’s.JavaScript included in the iframe has limited access to the parent. An iframe from a different domain can’t access the parent’s cookies.Iframes are one to two orders of magnitude more expensive to create than other types of DOM elements.An alternative way to insert ads with better performance would be for the main page to create...

The local trains in Hyderabad, also referred as MMTS (Multi-Modal Transport System), are one of the best modes of transport within the city. There are often long queues for the tickets. I noticed that though the Automatic Ticket Vending Machines (ATVM) are present at almost all local stations (introduced in February, 2010), they are not patronized due to lack of awareness and inadequate advertising.ATVM Smart Cards can be used to purchase...

Excerpted from "Chapter 7: Writing Efficient JavaScript" of the book "Even Faster Websites":Performance .. is not just about how long it takes for the page to load, but also about how it responds as it’s being used.Out-of-scope variables take longer to access than local variables.A very common mistake that leads to performance issues is to omit the var keyword when assigning a variable’s value for the first time. If an array item or object property is used more than once, store it in a local variable to speed up access to the value.Generally...
