WebPageTest is a powerful online web performance testing & analysis tool that has been adding a lot of interesting new features .  Their list of test locations to check a page from is growing (currently 17) & now includes Delhi, India. It makes it easy to do "what-if" testing on production pages by showing what performance gains can be achieved by removing ads, widgets, JavaScript. It looks simple on the surface but once you start poking around Advanced Settings & see its analytical review of web pages you test, you'll wonder how it's even free. I highly recommend this tool to web developers who want to improve performance of the web pages they build. If you never tried this tool or gone through it superficially, check Patrick Meenan's  video to get started and learn directly from the creator of the tool.

For years, the JavaScript section at W3Schools.com has been a indispensable source of reference for me . It will now not be my only source. After going through Stephen Walther's JavaScript Reference built with HTML5 & jQuery, I'm impressed with all the useful & up-to-date information that it contains. Unlike W3Schools which shows what browsers support (or don't support) a particular method or property, without explicitly specifying the version... ...this new Reference shows which browsers support each of the Objects, Functions, Properties, Statements, Operators, Comments, Directives. Only the latest versions of popular browsers are taken into account & surprisingly Opera is excluded. The complete source (15.2MB) of this HTML5 JavaScript Reference application is available for download & review. Update(14/Jan/11): If you work with JavaScript, also get this bookmarklet -  Steve Souders has created a meta-bookmarklet that includes DOM Monster & a

If you like web page performance analysis & optimization tools like YSlow, you will love DOM Monster (thanks @souders) "DOM Monster is a cross-platform, cross-browser bookmarklet that will analyze the DOM & other features of the page you're on, and give you its bill of health." The good thing about this tool is that you wouldn't have to update it when a new version comes out as it is in the form of a bookmarklet .

Al Jaffee is a tireless satirist , inventor of the MAD magazine “fold-in” 1  & my all-time favorite cartoonist . At 89, he is MAD magazine’s oldest & most prolific artist, having actively contributed to it for over five decades. His biography titled Al Jaffee's Mad Life tells the tragic story of this creator of incredibly funny cartoons and how this “master adapter” has surmounted overwhelming odds. His childhood was short-lived as he had a overly religious & negligent mother & a caring but absent father. His mother uprooted him & his three brothers from the US & the twentieth century and moved them to their native country of Lithuania which was still in the nineteenth century in terms of development. His father’s career as a manager at a department store took a hit and progressively went from bad to worse after he had to transport his family back to the US not once but twice. Despite flitting between countries & cultures, Al adapted well to difficult
