Think Vitamin » John Resig on Advanced Javascript to Improve your Web App - Annotated
-
When it comes to performance, there are a number of things in JavaScript, three of which are fairly easy, but especially so in jQuery. One is event delegation. Event delegation is a technique that routes around the traditional method of binding events. What I mean by that is typically when you attach a click handler to an element, you’re attaching a click to every single element that you want to attach to. This can be really costly. If you have a table with a couple of thousand table cells in it, that is going to be a lot of click handlers to attach.
Event delegation is whenever you attach a handler to some parent element up the tree, for example you attach it to the table itself rather than each individual table cell, and this takes advantage of the browser’s native event bubbling. What that means is when the user clicks on the table cell, the event will bubble up the tree, up to the table, and you can now handle the even there. That’s event delegation.

The
Daily Newsand
Inquirerare going back on the auction block next week, after a potential sale to a group of hedge funds collapsed yesterday under opposition from Teamster delivery drivers.
Federal bankruptcy Judge Stephen Raslavich ordered a new auction in his courtroom a week from tomorrow, without any contingencies for labor agreements.
Greg Osberg, chief executive of the hedge-fund consortium that agreed last April to pay $105 million in cash for the newspapers, said the group intended to bid and prevail again, this time with more clout to deal with the balking Teamsters.

Op-Ed Columnist - A Recovery’s Long Odds - NYTimes.com - Annotated
just opinion...
-
Americans are not being honest with themselves about the structural changes in the economy that have bestowed fabulous wealth on a tiny sliver at the top, while undermining the living standards of the middle class and absolutely crushing the poor. Neither the Democrats nor the Republicans have a viable strategy for reversing this dreadful state of affairs. (There is no evidence the G.O.P. even wants to.)
Robert Reich, in his new book, “Aftershock,” gives us one of the clearest explanations to date of what has happened — how the United States went from what he calls “the Great Prosperity” of 1947 to 1975 to the Great Recession that has hobbled the U.S. economy and darkened the future of younger Americans.

Remarkable Creatures - Hybrids May Thrive Where Parent Species Fear to Tread - NYTimes.com - Annotated
- While one might think that these oddities are examples of some kind of moral breakdown in the animal kingdom, it turns out that hybridization among distinct species is not so rare. Some biologists estimate that as many as 10 percent of animal species and up to 25 percent of plant species may occasionally breed with another species. The more important issue is not whether such liaisons occasionally produce offspring, but the vitality of the hybrid and whether two species might combine to give rise to a third, distinct species.

The Test Machine - The Daily WTF - Annotated
- The Test Machine seemed a bit out of place as it sat there, nestled between cubicles in Christophe’s office. Actually, calling it a “test machine” seemed a bit inappropriate, too, much like calling an aircraft carrier a boat, or referring to a house mover as simply a truck. It was huge – no less than seven feet tall, four feet wide, and three feet deep – and weighed a solid ton or two. This marvelous machine was as modern as it was massive, sporting several state-of-the-art computers, power supplies, instruments, relays, ignition coils, fuel injectors, and everything else one might need to test automotive electronic control units (ECUs).

SciDB: Relational daddy answers Google, Hadoop, NoSQL [printer-friendly] • The Register - Annotated
- Mention "relational databases" and a few peoples' names might spring to mind: Oracle's Larry Ellison, thanks to his billions, or Monty Widenius, main author of the ferociously popular MySQL. Geekier types might plump for Oracle's former Dr DBA Ken Jacobs or open-sourcer Brian Akers, who helped architect MySQL.

Intel's walled garden plan to put A/V vendors out of business - Annotated
- SAN FRANCISCO — In describing the motivation behind Intel's recent purchase of McAfee for a packed-out audience at the Intel Developer Forum, Intel's Paul Otellini framed it as an effort to move the way the company approaches security "from a known-bad model to a known-good model." Otellini went on to briefly describe the shift in a way that sounded innocuous enough--current A/V efforts focus on building up a library of known threats against which they protect a user, but Intel would love to move to a world where only code from known and trusted parties runs on x86 systems. It sounds sensible enough, so what could be objectionable about that?

Civil Rights Photographer Unmasked as Informer - NYTimes.com - Annotated
-
ATLANTA — That photo of the Rev. Dr. Martin Luther King, Jr. riding one of the first desegregated buses in Montgomery, Ala.? He took it. The well-known image of black sanitation workers carrying “I Am a Man” signs in Memphis? His. He was the only photojournalist to document the entire trial in the murder of Emmett Till, and he was there in Room 306 of the Lorraine Hotel, Dr. King’s room, on the night he was assassinated.
Ernest C. Withers courtesy Smithsonian Institution
Withers was often called the Original Civil Rights Photographer, for images like this 1961 shot of the Memphis Greyhound bus station.
But now an unsettling asterisk must be added to the legacy of Ernest C. Withers, one of the most celebrated photographers of the civil rights era: He was a paid F.B.I. informer.

3-D Printing Is Spurring a Manufacturing Revolution - NYTimes.com - Annotated
-
A 3-D printer, which has nothing to do with paper printers, creates an object by stacking one layer of material — typically plastic or metal — on top of another, much the same way a pastry chef makes baklava with sheets of phyllo dough.
The technology has been radically transformed from its origins as a tool used by manufacturers and designers to build prototypes.
