MSP Humphrey terminal: A modern ghost town

Posted in Computing, Events, Research, Science, Travels on July 11th, 2008

A modern ghost town
When I fly to conferences I tend to take the low cost carrier, whatever that happens to be. Much of the cost is coming out of my pocket, and I’m cheap (’cause the conferences never are). For GECCO [1], AirTran was the winner, with a price a hair under $200 round trip, which was quite a lot less than I was expecting to pay for the flight. One little tidbit I didn’t really appreciate until several weeks after I booked the flight was that AirTran flies out of the Hubert H. Humphrey (HHH) terminal of the Minneapolis-St. Paul (MSP) airport, and I’m currently adrift in the empty, echoing terminus of HHH with a handful of fellow travelers.

For those unfamiliar with MSP, the vast majority of flights use the Lindbergh terminal, and I suspect many people pass through MSP with nary a clue that the Humphrey terminal exists. I think I’ve only flown through HHH once before, on a Sun Country flight to a conference several years ago, and I’d pretty much forgotten what it was like over here.

I knew I’d have a couple of hours to kill at the airport between the arrival of my shuttle from Morris and my departure, and I figured I’d grab some lunch and try to continue revising our GECCO talks. This, however, failed to take into account my departure from the Humphrey terminal instead of Lindbergh. The Lindbergh terminal is a nice airport, with lots of restaurants (some of which are pretty decent) and even a passable book store or two. HHH is a small terminal (10 gates) servicing a ragtag group of low cost and limited traffic airlines.

It’s like a ghost town, but with airplanes.

There was almost no one here when I arrived. Only one of the dozen or so AirTran desks was open, there were no customers in sight, and I was able to just walk right up. Security also only had one queue open, but there were only four or five of us going through at the time, so it was again “Step right up and off you go”. The waiting areas were almost completely empty when I got here, and now (probably 30-40 minutes away from boarding) have a smattering of folks.

All this is most definitely to the good, especially when compared to some of the chaotic and stressful check-ins and security checks we’ve had in some of our recent flights.

The downside is that there are pretty much zip in the way of services or staff. There are a whopping two coffee/sandwich shops in the whole terminal, one on either side of security, and one bar/restaurant. After that we’re down to a magazine rack and a few vending machines. And the coffee shop inside of security didn’t have anyone at the till when I first came through.

Arguably less good, and certainly weird. No one’s going to mistake it for Heathrow or O’Hare, I promise you.

The real bummer, of course, is that there’s no free wifi here (or at the Lindbergh terminal). $4.95 for an hour, or $7.95 for the day.

Wonderful. Almost as wonderful as the fine $3 sandwich that cost me $7 for when the coffee shop finally opened up.

I’m looking forward to not flying for quite a while (perhaps as much as a year!) after I return from this trip. It’s nice being other places, but getting there isn’t always loads of fun, and it tends to suck environmentally.

1 GECCO = Genetic and Evolutionary Computation Conference, one of the two or three big international “mega” conferences in evolutionary computation. To be honest GECCO is much bigger and more circus-like than would be my preference. I’m much happier at smaller gigs like EuroGP, but that’s during the school year, and at an awkward time, and a lot more expensive to get to, so I’ve attended a lot more GECCOs than EuroGPs :-(.

A tale of misery and (file format) woe

Posted in File formats, Politics, Sabbatical on July 5th, 2008

Filing cabinet fence

As we were car-less in the UK last year, we would rent wheels at various times when we needed to move all three of us and lots of stuff over what passes for long distances on the small island. Our last rental, for our last week between Spain and our return back to the U.S., was from Enterprise. When we dropped the car off at the airport their desk was closed, so I just plopped the keys in their little return safe.

Today I got an e-mail with the receipt. As an attachment. In “.MDI” format. Whatever the hell that is.

I was pretty sure we were going to find out that this was a M$ format before I’d even bothered looking, as it’s almost always people that have been sucked irretrievably into the M$ vortex that blithely send out files in annoying proprietary formats without considering the possibility that not everyone has sunk loads o’ dosh and a major organ into M$ software. I was right. It turns out that it’s Microsoft Document Imaging format, which apparently scans physical documents and converts them into TIFFs. But instead of then using the open, nigh on universally supported TIFF, they wrap (I’m guessing) that in their own goofy MDI format so people like me can’t open the documents.

Charmed. I’m sure.

Nothing I tried (and I tried quite a lot of things) would open this MDI file up, so I (nicely) wrote back and asked if he could re-send the file in an open format, like plain text or PDF. A model of restraint, I was. Really.

They promptly sent a second message with a new attachment in “.doc”. Good on the promptly. Less winning on the “.doc”, since that’s clearly not an open format. Happily, however, NeoOffice was able to open it up, sparing me a second round of e-mails with this nice person.

And what, after all this fun, did this remarkable M$ Word document contain?

A single, small image.

The image looks like a scan of a small bit of a spreadsheet. A small bit. No names (theirs or ours), dates, or any other standard “invoice” information. Just 10 lines of text, four of which are labels, four of which are actual entries (the rental amount, VAT, etc.), with the rest being sub-totals and totals.

In other words, a ton of machinery to obfuscate a quite small bit of information.

I just hate it when that happens…

Upgraded to WP 2.5.1

Posted in Weblogs and CMS on July 5th, 2008

You must protect yourself from those evil marketing rays
Just finished upgrading to WordPress 2.5.1, and the dashboard is quite different. Not sure yet whether it’s better or worse, but definitely different. I like some of the nifty Ajax stuff that’s been added in the last few updates - these (good) web apps just get spiffier and spiffier!

Wordle makes tag clouds all pretty

Posted in Art, Computing on July 4th, 2008

Just stumbled across Wordle, a neat tag cloud/text visualization tool, and am having way too much fun.

Some of my most common Flickr tags (click on the cloud to see it bigger on Wordle’s site):

The contents of the front page of my blog as of 3 July 2008:

Nic’s blog tag cloud

I like how the latter captures our time in Spain quite nicely, and I really like how Wordle can intermingle the ascenders and descenders. Wordle can grind pretty hard on your CPU, but there are lots of neat options to play with and some very fun results to be had. w00t!

Thanks to banned photography inc for the tip.

Can we please remember that M$ hasn’t completely taken over the world?

Posted in Computing, Education, Sabbatical, Web development on May 22nd, 2008

I just had to take four on-line safety courses here at Essex in order to get money from our research grant. I’ll spare you the horrors, although I did twitter on about of some of them as I went as a sanity saving device, and will share a couple:

“Keeping your workstation and office tidy is crucial to short-term and long-term health and wellbeing.” I am doomed.

[The] Irony of spending much of an hour wading through a tedious online lesson on risks of spending too long at the computer is not lost on me.

As if the exams themselves weren’t annoying enough (and trust me, they were), the people that assembled them implicitly assumed that everyone in the world is in Microsoft’s pocket. I eventually became so frustrated that when I’d verified that I’d passed them all, I sent the following along to the folks that put all this together:

While I’m here, I should mention that there were several pieces of media that seemed to assume that one was on a Windows box. Quite a few images (clip art, I assume) didn’t load on either a Linux box or a Mac. Also the PowerPoint in the “Working at height” lesson assumed that you had PowerPoint or some compatible viewer, which isn’t always going to be true.

None of these problems were fatal for me. There didn’t appear to be important content in any of the images that I couldn’t view, and I was able to view the PowerPoint file in another program. Still they were confusing and frustrating (especially at first), and it would presumably be fairly easy (if somewhat tedious) to convert them all to a more standard and open format.

Far too many photos from Dagstuhl

Posted in Computing, Events, Photography, Research, Sabbatical, Science, Travels on May 15th, 2008

A view not often seen

Regular readers here will likely remember various past posts extolling the virtues of Dagstuhl, this really wonderful computing research facility in Germany. I’ve been lucky enough to attend several seminars on the Theory of Evolutionary Algorithms in the past, and have taken (and posted) quite a few photos from those trips.

A few months ago I had the (totally) unexpected pleasure of being contacted by Christian Lindig, a member of Dagstuhl’s scientific staff, and asked if I would be willing to return to Dagstuhl for the specific purpose of taking photographs for them. They’re apparently in the process of re-doing all their brochures and such, and liked what they’d seen on Flickr.

As a result I’ve spent a very pleasant few days back at Dagstuhl in some gorgeous spring weather (I’ve only every been here in the winter before), enjoying the company of a fine group studying the Design and Analysis of Randomized and Approximation Algorithms. (They’ve been very patient with an intruder who always seemed to be waving a camera about, and for this I am grateful.)

I’ve taken something over 1,000 photos, with a few more planned for tomorrow morning before I leave. Some of the participants have asked if the photos will be made available. I have uploaded everything I’ve taken this week to my “events” account on Flickr, all under a Creative Commons license, which means that participants are welcome to download and use any that they wish, as long as they provide attribution. (Note that I am not, and can not, provide any sort of permissions from individuals photographed - that’s their right and prerogative. If you want to use someone here in a beer ad, you need to get their permission first.)

Where are they all?

  • Everything I’ve taken this week is on my “events” account.
  • I also have a Dagstuhl set on my “real” Flickr account that has some of my favorites (with cleaning, cropping, etc.) from my various visits to Dagstuhl. At the moment this set is heavy on shots from previous trips, but I hope to add more from this visit as time allows.
  • Earlier this year I posted everything (without cleaning or editing) from the Jan/Feb seminar on Evolutionary Algorithms to my “events” account.

It’s not yet clear what all Dagstuhl may do with these, but they will contact anyone who is recognizable in a photograph for permission before using your image in any of their materials. If anyone objects to being included in these vast oceans of photos, please let me know and I’d be happy to remove the photo in question.

Thanks again to Christian for inviting me out to Dagstuhl, and to the Randomized and Approximate Algorithms group for being patient “hosts”. Enjoy the photos!

How times change; how books change

Posted in Books, Computing, Education on May 3rd, 2008

Studying for class by jakebouma
Penguin’s promoting some exploration of the concept of “book” in their We tell stories series, where six authors have contributed new works, each of which explores some aspect of on-line story-telling, sometimes quite distinct from more traditional printed books.

Not all of these are equally successful (I thought the idea of “The 21 steps” was better than the execution). My favorite of these is probably “Hard times”, by Matt Mason and Nicholas Felton. It’s a short, but (for me) very effective collection of data points making it clear how much things have changed and are changing, and hinting about what it might all mean down the road. Most of the info was at least somewhat familiar to me, but I love the way the details are brought together into a compact compelling argument — a sort of data poetry.

From Part VII: “Ideas are travelling faster” (crediting the data to Seth Goodin’s Unleashing the idea virus):

The time required to achieve Ten Million Users:

  • Radio: 40 years
  • Television: 15 years
  • Netscape: 3 years
  • Hotmail and Napster: < 1 year

Part IX-A has a tremendous title — “Our parents killed bad ideas with music. We kill bad ideas with new buiness models” — and delivers excellently on that promise.

Thanks to jakebouma for the cool photo.

So much to do - so little time

Posted in General, Research, Science on May 3rd, 2008

Sorry for the lack of activity here - an EPSRC grant with Riccardo came through, which is big happy news. The downside is that there’s a ton of research work to be done in a very short period of time. We were lucky enough to have Ellery Crane visiting for the last two weeks, and the two of us did some pretty massive hours while he was here. We got a bucket of really good work done was he here; we built several large new systems and got some early results that suggest probably at least a couple of papers.

I’ll try to post at least sporadically in the upcoming weeks, but I suspect things are likely to be light here well into the summer.

Education’s an investment, not an expense!

Posted in Education, Podcasts, Politics, Research, Science on April 1st, 2008

Wrapping one's head around the data
Just did a pile o’ dishes and listened to a SciAm podcast featuring the remarks of Robert Rosner (head of Argonne National Laboratory). The short version is that science (and, I would argue, education in general) is a matter of necessity plus vision. First, science is not a luxury, but instead a necessity:

Without the science base, you cannot build an industrial base.

Second, science requires long term vision and public and private support in in basic research. It typically takes decades for culture changing technologies to move from the basic idea to ubiquity; Rosen gives as examples railroads, airplanes, transistors, computers, the internet, and lasers. The question then is

How do you convince the politics and the public that that lag in fact is real and that if you don’t make the investments … today … we’ll be lagging things that other folks that are making the investments

Rosen is (quite reasonably) focussed specifically on the question of support for science, but points out that this is part of a larger trend of irrationality in the U.S.:

But we all know that in the United States there are long traditions of anti-intellectualism, of what the Times today also refer to as anti-rationalism, the idea that there really are no facts, it’s all opinion, the idea that scientists [are] just playing their sand box and don’t connect with anybody.

What it really comes down to is a distressingly common failure for Americans to see any form of education (science or humanities, K12 or university) as a necessary investment in the strength and future of our society and country. For me this has become a useful litmus test to separate sensible conservatives (who understand the economic necessity of investment in key areas) from the wingnuts that have come to dominate the Republican party (who spout anti-intellectual nonsense while shredding schools and lining the pockets of themselves and their friends).

Eisenhower understood the practical necessity of an interstate road system, and encouraged and supported that investment. All Shrub can seem to invest in is Halliburton and their ilk.

Things to think (and ask) about in this happy election season.

A little wind-swept

Posted in Computing, Events, Photography, Research, Sabbatical, Travels on April 1st, 2008

A little windswept

On Friday after the EvoStar/EuroGP events wrapped up, Bill (Langdon), Riccardo (Poli), Tyler (Hutchison), and I spent a couple of hours being tourists in Naples, starting at Castel dell’Ovo ("Egg Castle"). This castle sits on a little island just off the shore right in front of our hotel and the conference center, so we saw it the whole time we were there. Most of our time there was gray, and often wet, but happily Friday afternoon turned clear and blue (if blustery). So we walked over to the castle and wandered about chatting and admiring the many views.

Here we have Tyler and Bill being blown about a bit, with Vesuvius dimly visible across the bay in the background. I love what the wind’s done to Tyler’s hair and Bill’s clothes :-).
