More silliness at Newark

November 7, 2009 / Nathan Zeldes / 1 Comment

We saw how the electronic boards at Newark Liberty airport made the ridiculous omission of adjusting for the Daylight Savings move. Evidently this is not an exception: something is very wrong with that airport’s electronic signage.

These guys have an “Airtrain”, an internal elevated light rail system for moving between terminals. The train has two parallel tracks, and there are electronic signs at the stations to indicate which is which. Thus, the sign in the photo indicates that the train on the left goes to terminals A,B, and Parking areas 1 through 3; the other train goes to P4 and to the train link to NYC.

Except that they also had a backup system. They placed a uniformed woman with a loud voice that announced repeatedly: if you want to go to terminals A, B, and P1-P3 you must take the train on the right. The signs, so convenient and visible, were displaying the wrong information.

You’d think the lady, who was no doubt equipped with a cellular phone, could set the error straight in a jiffy by calling some control room; but that didn’t occur to anyone. And after all, who are you gonna trust: a computerized board, or a well-meaning person of your own species?

Mr. Babbage’s marvelous engine

November 5, 2009 / Nathan Zeldes / 2 Comments

In the US, where I just gave a lecture at a conference on Information Load and Overload, and of course I found the time to visit the wonderful Computer History Museum in Mountain View. This is always a delight, but this time they surpassed themselves: they demonstrated the newly built Difference Engine #2 in action!

Charles Babbage’s incredible but never-built 19th century calculating machine was first realized in the nineties by the Science Museum in London, and now Microsoft millionaire Nathan Myhrvold commissioned this second replica. This one is complete with the printing mechanism; you crank the handle at one end, sequential values of 7th order polynomial functions are computed by the whirring mechanism, and ready-to-use plaster casts for printing the numbers in table form come out the other end, complete with multi-column formatting. The dance of the mechanism is really a thing of beauty; a visit to the museum is very recommended.

I saw it, and I have the photo to prove it!

A time lapse at Newark

November 2, 2009 / Nathan Zeldes / 4 Comments

Had to take a flight out of Newark airport on the morning after the move from daylight saving to winter time. The preceding evening I took good care to set my alarm clock and wristwatch back the required hour, and took off to the airport in the morning. And when I got there, I was amused to see the many and wonderful electronic displays that are all over the place all showing an hour late.

Now, these boards and clocks are all computer controlled, and you’d think they’d let the computers handle the time shift; my own Notebook and Smartphone both did without human intervention. But even if they installed systems based on human clock-setters, like they did with the big clocks of earlier eras, surely they could’ve done the job right – and, if not, corrected the mess when it became all too visible in the morning?…

Evolution of airplane movie technology

October 26, 2009 / Nathan Zeldes / 0 Comments

Flying to the States on a Continental 777, my favorite jetliner, alternating my attention between my notebook and the video screen in the seat back in front of me. The latter is a new model, fitted to every seat in the cabin. The technology has been evolving ever since I stared flying to America back in the eighties.

At first they introduced real movie screens, one at the front of each cabin, with a projector that would show one single movie at a time. Your viewing pleasure was a matter of luck – a tall passenger in front, or a poor seat location, could wipe it out – but passengers loved it: a movie – in the sky? Wow!

Then came TV screens jutting out under the ceiling, giving better viewing to more passengers; still one movie at a time, chosen by the airline. The passengers had no choice of content or screening time.

More recently we got personal screens, with multiple movies to choose from. Typically we’d have a dozen movies, but they all ran in synch – all started at the same time, and if you switched on in the middle you saw half the movie. Of course on a transatlantic flight there was time enough to take in the missing half in the next cycle. So – each passenger now had the choice of which movie to see but not when.

So this flight, they’ve installed larger, wider screens and with them unbelievable choice. There are hundreds of movies and TV episodes to choose from, and each traveler can start any of them at any time, and even pause, rewind or FF during the movie. Perfect choice.

What will they think of next, then?

Check out my new Infomation Overload blog!

October 15, 2009 / Nathan Zeldes / 0 Comments

Yep… I started a second blog, this time one dedicated to my work specialty and passion: fighting Information Overload. It’s called “Challenge Information Overload” and you’re most welcome to read it here.

I plan to continue posting here on the Commonsense Design blog, albeit possibly at a somewhat lower update rate (there are only so many hours in a day :-)).

Headup wordpress plugin – add semantic browsing to your blog!

October 14, 2009 / Nathan Zeldes / 0 Comments

I’ve mentioned the headup publisher widget before. This nifty add-in identifies entities (places, people, companies, books, etc) mentioned in a site it’s installed on, marks them up with a dotted underline, and when you mouse over them a small pop-up comes up with information, news, photos and videos about that place/person/whatever.

That was then. Now Semantinet, the start-up in Herzliya where I work one day each week, has packaged the capability as a WordPress plugin, which means that a blogger can add the capability to any WordPress blog in a mere minute or two. If you have a WordPress blog, you can download the plugin here.

What’s more, the product had evolved, and it now includes a tab called “friends” in addition to the ones for photos, videos, and the rest. This tab – once you connect it to your Facebook account – shows you how the entity being viewed is connected to the people you know, like which of your friends live in the place or work at the company.

Pretty powerful capability – and easier than ever to include. Which is what I just did – mouse over the marked up words anywhere on this blog and see it in action!

We aren’t all noobs!

October 11, 2009 / Nathan Zeldes / 0 Comments

One gripe I have with the help systems in many consumer software applications: they’re written with the assumption that we users are all clueless newbies.

Take the Microsoft Office tools: they have many advanced and powerful capabilities; it is both interesting and useful to know what exactly they do. But the Help system only gives you the step-by-step “How To”. Say you want to try the Auto-Summarize feature of MS Word, and are curious what exactly it does (I mean, beyond automatically creating a summary). How does the feature work? What algorithm is involved? How does it identify the important parts of the document? Knowing this is not only interesting; it can let us users know what to expect, and how to use the feature better. But all we are served is a sequence of steps like

On the Tools menu, click AutoSummarize.
Select the type of summary you want.

And so on. Necessary and useful for the computer-naive types, but not sufficient for the technical or curious.

I sometimes imagine the day when I’ll run into a button (perhaps in Word 2015?) that says “Stop world hunger”, and when I check it up in Help it will only say

To stop world hunger, click the button Stop world hunger.

C’mon, folks, you develop awesome code – let us know what is going on behind the scenes. At least give us a link to this information after the stuff the noobs use is listed…

The delight of postage stamps

October 2, 2009 / Nathan Zeldes / 5 Comments

Just got a letter from the UK, and it had this colorful stamp on it.

Postage Stamp

For an instant, I felt that special twinge of joy that an interesting stamp elicits; only after a moment did I remember that (a) I no longer collect stamps, not since I was a kid I don’t, and (b) none of my friends does, nor do they have kids that do that I might give the stamp to.

This is a shame, really, because postage stamps have a built-in ability to delight. They are often beautiful, they come from wondrous distant lands, they have a story to tell in their miniature image, and they are eminently collectible. In this way, every letter that you or your circle of friends and relatives received had the potential to surprise you with a “bonus”, a tiny capsule of serendipity where the stamps it bore could be boring or fascinating, depending on the luck of the draw.

All this may soon be over. I don’t know whether stamp collecting is on the decline (I suspect serious adult collectors do exist, but children may be more into video games these days). But the stamps themselves may soon be obsolete. People send less personal letters since the advent of email, and I’ve just read that the UK is planning postage stickers you can buy online and print out, and these have a bar code, not a picture (they also took out the queen’s ever-youthful profile we see in the stamp above, causing much consternation).

But meanwhile stamps still exist, and I know of one guy who makes full use of their joy-creating potential. He is a fellow History-of-Computing collector, and an eBay seller of slide rules; when I buy one from him it invariably arrives in an envelope covered with a mosaic of small-denomination stamps, each one different, all beautiful.

The riot of color is so cheerful that I collect these envelopes. What a nice way to delight one’s customers!

Thoughtless signage in lovely Florence

September 29, 2009 / Nathan Zeldes / 0 Comments

My relatives returned from a trip to wonderful Firenze, and shared some terrible experiences trying to get their rental car back to the rental office in that ancient city’s dense traffic. Which brought to mind my own experience in the matter some years back.

Firenze

I was trying to steer a course through all the one-way streets back to the car drop off location in downtown Florence, and no matter how hard I tried to navigate the narrow streets with my map, I always kept finding myself forced back to the same spot by the one-way street signs. The only way to the rental office seemed to be through a street blocked with a “no entry either way” sign.

It was only after the second or third try that I noticed a tiny text sign under the round no entry sign.

It said “except for car rental returns”.

In pure Italian...

Couch potatoes vs. Movie theaters

September 25, 2009 / Nathan Zeldes / 0 Comments

One sign of the times is that movie halls are closing one by one around us, victims to the surge in electronic alternatives. We know this from direct observation – they really are closing – but I had an unexpected demonstration of this fact in a TV ad.

The ad was by the Hot cable company we subscribe to, and was aimed to convince us to use their Video on Demand service. It showed how difficult it supposedly is to get a movie without their VOD: it graphically showed how you need to go down 20 stairs to the street, walk a mile to the Videomat, check if it has a movie you want. No? Walk another mile to the video store, get the movie, walk back… you get the idea.

Nice ad, but what amused me is that 20 years ago they would’ve said “Go down 20 stairs, get in the car, ride downtown, and enter the movie theater”. These days, that just isn’t seen as a viable alternative! You’re expected to either slump on the couch in front of a cable movie, or rent a video and slump in front of that… and these guys want to deprive you of even the little exercise you’d get walking to the video store 🙁
