On this day in 1969, The Beatles made their last public performance, on the roof of Apple Records in London. Let’s take a look.

A couple of months ago I pointed you to a story about using 3D printers to print a guitar. Here’s a story about using 3D printers to print dresses for a fashion show in Paris.

The next earth-shaking tech revolution is happening now: Try and imagine what the world will be like when the need for factory production is minimized and the ability to manufacture on demand is placed in the hands of the individual.

No? Time to think again: G+ is the second-largest social network on the planet. ZDNet has the stats.

With, evidently, another PR fail. Addicting info reports.

Here’s a little experience I found interesting.

I was in Macy’s today buying a new suit. I wanted to get a white French-cuff shirt, and I had two choices: a Donald Trump shirt and a Sean John shirt.

Normally I really don’t care about brand names all that much; I just want a comfortable good-looking shirt, so a case like this would usually be a six-of-one-half-a-dozen-of-the-other decision.

Except that Trump has been such a profoundly absurd gasbag on the political scene over the past year. “I guess I’ll take the Sean John,” I told the salesman, “I just can’t bring myself to buy a shirt with Trump’s name on it.”

He told me I was the third person today to say so.

I wonder how many other people aren’t putting money into Trump’s coffers for similar reasons.
