Yesterday, The Wall Street Journal did a special Technology Report section, made up of excerpts of selected interviews from the seventh D: All Things Digital conference.

It includes sessions with Microsoft (MSFT) CEO Steve Ballmer ringing in Bing; Yahoo (YHOO) CEO Carol Bartz trying to find a reason to curse at BoomTown; Roger McNamee and Jon Rubenstein of Palm (PALM) introing the Pre; Twitter Co-Founders Biz Stone and Evan Williams saying “we do not know” was the microblogging service’s mantra; entrepreneur Mark Cuban talking smack about the Internet; cable legend and Liberty Media (LMDIA) Chairman John Malone cracking wise; and NBC Universal (GE) head Jeff Zucker doing the Hulu.

As the event’s hosts and interviewers, Walt Mossberg and I also did a mini-essay about the event, in which we continued to jest about various goofy names that digital eras had been given.

As we wrote:

“Before the seventh D: All Things Digital conference, which took place last week in Carlsbad, Calif., we declared—with our tongues firmly planted in our cheeks—that Web 2.0 was over and Web 3.0 had begun.

While we were poking fun at Silicon Valley’s incessant need to stick a hyped-up catchphrase on each and every development, the use of such jargon was actually important, because we think that the digital sector is now moving full bore into an entirely new cycle of profound change.”

We decided to focus in on smart phones and the mobile platform as critically important in the next era, although what we were talking about was the complete integration of computing into every part of our lives in a way that is seamless, ubiquitous and, ideally, dead simple.

As we also noted in the essay:

“From using easy gestures to grab any piece of information from the Web to having powerful computers in the palm of your hand to being able to quickly dip into complex social networks to getting real-time information from across the globe as it happens, this is an era when computing could become as integrated and invisible as electricity and just as important.”

So read all about online and in print (if you saved a copy) and you can also watch video highlights on this site too.

But, best of all, All Things Digital be posting the full video of all the sessions on this site soon.

Oh dear, I always forget that the camera is turned on 24/7 these days, knows all and sees all and then sticks it on YouTube.

Like this moment for me that came during a speech I gave last week at the Software & Information Industry Association’s NetGain conference in San Francisco, which was titled, “How I Stopped Worrying and Learned to Love the Tweet: What Interactivity Really Means for Real Businesses.”

While I talked about a lot of key trends, from persistent data to ubiquitous screens to the importance of voice, touch and gesture in future computing to the always-on state of online presence, it was this moment in the Q&A part at the end that got most noticed.

Someone had asked me what devices I use and also wondered if I had bought a Kindle from Amazon (AMZN).

Indeed not, as you will see, as I admitted that I was waiting to overpay for any similar and doubtlessly overpriced e-reader Apple (AAPL) will foist on me someday.

Here’s the video (please ignore my itchy ear thing and haggard look):

Designed on paper by English inventor and mathematician Charles Babbage (pictured here with his creation) and built to his specifications, it is on loan for one year from former Microsoft (MSFT) tech guru Nathan Myhrvold.

(Myhrvold will be a speaker at our sixth edition of D: All Things Digital, taking place in exactly two weeks.)

Babbage was one of the great stories of the early computing age, a man who intricately designed one of the first automatic computing engines to battle the inaccuracies endemic in figures calculated by hand.

As the overview of this video relates: “Engineering, astronomy, construction, finance, banking and insurance depended on printed tables for calculation. Ships navigating by the stars relied on printed tables to find their position at sea. The stakes were high. Capital and life were thought to be at risk … it was not only the grindingly tedious labor of verifying a sea of figures that exasperated Babbage, but their daunting unreliability.”

Despite his laborious and detailed designs, though, Babbage never actually built his creation.

But other geeks took up the task and there are two now, both called Difference Engine No. 2, one in London and one now at the museum. Each has 8,000 parts, weighs five tons and measures 11 feet long and seven feet high.
