I tend to scribble a lot
Creative Commons License photo credit: Unhindered by Talent

When I edit, I tend to scribble a lot, even when it’s my own stuff (or the writing of people I really like). Last January, for example, I took a set of photos after scribbling all over a paper that Riccardo and I were working on for GECCO. This paper went on to win the Best Paper award in the genetic programming track at GECCO last month, so I’d like to think that all this editing had some value :-).

I posted the full set over in my events account, and I plan on using some of them to show my students that I’m not just being mean to them — I’m mean to everyone, myself included!

This showed up here now because a publisher contacted me about using it in a college writing textbook. I figured I’d clean it up and post the full size version.

Any suggestions for cool lawnmowers?

First, let’s set the stage:

  • I really don’t like the traditional suburban lawn. Tons of chemical, energy, and effort to create and maintain a biologically unstable mono culture so that I can … putt … or something. So, so silly.
  • I’m also a big non-fan of petrol powered lawnmowers. They’re noisy, smelly, polluting beasts that beat the crap out of the grass, ripping it instead of actually cutting it.

As a consequence we’ve explored a bunch of alternatives, but none have really worked terribly well. We really liked the idea of reel mowers, but our experience with several of them makes it clear that our lawn is way too uneven and bumpy for a reel mower. Sigh.

What would be perfect would be a solar powered Roomba-like robot mower. WeatherGirl correctly pointed out that this is frequently known as a “goat”; sadly, the city classifies goats as livestock rather than lawn tools, and we aren’t allowed keep livestock in town. Damn.

So, anyone have any ideas for an interesting alternative to buying a stinky petrol powered monster?

Thanks in advance!

UMM students are just so cool!

Posted in Computing, Education, Events, My writing, Research, Sabbatical, Science, Writing on March 30th, 2008

EuroGP 2008 - 495
As mentioned earlier, our paper “Semantic building blocks in genetic programming” with Brian Ohs (UMM ‘08) and Tyler Hutchison (UMM ‘07) was nominated for Best Paper at EuroGP 2008 in Naples, Italy.

We won!

That a paper co-authored with two undergraduates from a small, public, undergraduate liberal arts institution like the University of Minnesota, Morris, could win an award like this at an international science conference is just too damn cool. Well done to both Brian and Tyler!

In the hectic melee of the conference, most folks don’t have time to do anything more than skim the nominated papers, and usually not even that. This makes the talks a crucial part of an award like this, as much of the voting is based on them. Tyler (pictured above at Castel dell’Ovo in Naples) was a huge help in that regard. He flew over to the UK several days early so we could work on our talk, giving us the time we needed to revise and practice. He also produced a super cool little six page comic with a nifty introduction to our work that the audience could follow along with. We did a joint presentation, each covering about half the paper. Our talk was well received, and Tyler’s comic was incredibly (and deservedly) popular, and there’s no doubt that his participation was a huge help.

(And all this is on top of Brian and Tyler’s hard work and contributions on the paper itself. Obviously without that content we never would have had the paper accepted or nominated in the first place. So they both deserve huge kudos for that as well.)

Friday morning our paper was voted Best Paper by the conference attendees, and we were presented with a certificate, a box of Italian lemon cookies, and a box of Irish chocolates. All the Best Paper winners from the various EvoStar conferences and workshops also got to choose a free book from the Springer table. Tyler got a really cool book enitled Leonardo’s Lost Robots, and I got The forgotten revolution: How science was born in 300 BC and why it had to be reborn. (It was all terribly liberal arts of us - pretty much everyone else took evolutionary computation/artificial intelligence books of one form or another.)

Tyler upheld a fine tradition of our students making UMM look really good at conferences like this. From his deportment and grasp of the material, most people assumed he was a graduate student, despite the fact that the looks like he’s about 16 :-). He’s currently doing contract work as a web developer and designer, but is seriously interested in going to graduate school in the near future, and he definitely impressed the folks at the conference. I’ve been really lucky to work (and co-publish) with a string of great UMM students, and am looking forward to continue that with a very sharp student named Sara Lahr when we get back.

The trick for me (sometimes) is remembering just how good our students can be. The room we spoke in was this grand space of inlaid wood and marble that was quite a surprise in several ways. This was made worse by the fact that we were in the first session, so we had very little time to adjust and adapt. I was worried about running long (we had a lot of material to cover), and started to lose my nerve about having Tyler wandering around the room at the beginning handing out the comic. Tyler was really calm and collected about it, though, talked me down, and everything did in fact go really smoothly. The moral? Handouts are Good, really cool comics handous are Even Better, and I need to remember to listen to my students :-).

Thanks a ton to Brian and Tyler and all the people and offices at UMM that supported our work, and everyone who voted for our paper at EuroGP! Special thanks also to Riccardo Poli for hosting me on this sabbatical at the University of Essex. I’ve gotten a ton of cool work done here with Riccardo, including “A linear estimation of distribution GP system” at EuroGP, which was also nominated for Best Paper (and which I suspect was also strongly in the running).

I’ve dumped all the photos Tyler and I took in Naples onto my events account on Flickr. I’ll try to clean up a few to post to my main Flickr account in the next week or so.

A heck of a party!

Posted in Books, Computing, Education, Events, My writing, Research, Sabbatical, Science, Writing on March 27th, 2008


Last night’s unveiling of A Field Guide to Genetic Programming was a huge success! We had one of the poster “stalls” with 50 copies of the book that we’d purchased from Lulu as our initial “print run”. We were wearing cool t-shirts sporting that wonderful cover, had the nice poster shown to the right, and even had spiffy postcards with the cover to give away.

The book was a big hit with the Evo* crowd, and we sold out the full set of 50 pretty quickly. Lots of folks had us autograph their copies, many of which are now destined to be collector’s items with the signatures of all three of the authors. Some even have the signature of Tyler Hutchison, who did the nifty cover art for us and helped a lot with the roll-out.

There were tons of photos taken at our booth, including candids of us signing and working the crowd, and posed shots with our cool Field Guide shirts. People have promised to send us photos and links, so check back in the next week or two for some of the finest in EC book release amateur photojournalism! (And if you’ve got a photo from the event, or a nifty shot of your copy in its place of pride on your bookshelves, please pass it along.)

As mentioned before, the book is now officially released and available to any and all via lulu.com, both in an inexpensive printed form (what we were selling last night) and as a free downloadable PDF.

So go check it out - 50 whole Field Guide fans can’t be wrong!

Almost ready for EuroGP!

Posted in Art, Books, Computing, Events, My writing, Research, Science, Writing on March 22nd, 2008

EuroGP poster
We’ve ordered a couple of boxes of advance copies our book (a privilege of being the authors). They look really nice, and we’re quite excited about the grand unveiling on Wednesday at EuroGP! For those of you coming to Naples, definitely stop by our table at the poster session that night — you’ll be able to check out printed copies and maybe even score a postcard featuring that wonderful cover :-).

Whether you’re coming to EuroGP or not, we’ll be “turning on” the Lulu site Wednesday, so people can buy printed copies and download the PDF for free. As a teaser, the poster above contains the entire book — just really, really small! If you click on it you can see it a little bigger, but I still recommend waiting a few days for the Real Deal.

Thanks to Riccardo for using some of his major LaTeX mojo to create the mosaic of all the pages, and to Jess and WeatherGirl for their suggestions regarding the design.

JOCP! At revision 400!

Posted in Books, Computing, Education, My writing, Research, Science, Writing on February 28th, 2008

Revision 400 screenshot

It’s pretty cool when you update your repository and see

At revision 400

We just hit that on the genetic programming book that Riccardo and Bill and I are working on; we’re currently averaging close to 10 commits a day here in the final stages. We hope to wrap it up in the next 1.5 weeks and then off to the printers for fun (and no profit in the traditional sense)!

P.S. Anyone want to proof read a few pages? Get in touch and we can work something out.

Rainbow curves (Lost imagery)

Posted in Art, Computing, My writing, Research, Science on January 25th, 2008

Rainbow curves (Lost imagery)

As mentioned before, I’ve been pretty insanely busy, trying to get four different co-authored research papers ready in time for the submission deadline next week for one of the major conferences in my field. Part of the reason I’m busy is that I procrastinate, but part of it is that I’m damnedly slow. And an important part of that is that I spend roughly forever making and fiddling with graphs.

See, I just love a good graph. One of my great goals in life is to give a standard length (20-30 minute) conference talk where my entire collection of slides is just one gorgeous, illuminating, data rich graph. The graph would need to have all the information I want to convey and enough to support 20 minutes of me talking about it. So far I’ve not come anywhere close. I’ve occasionally had single graphs that could support more than five minutes of presentation, but I’m not sure I’ve ever hit 10. But I’m working on it.

In the meantime, I tend to collect vast whale bellies full of data (my research generates data with wild abandon), and then make plot after plot after plot, trying to figure out both what the data says, and how I can best share that with my potential audience. Hours and hours constructing different views on the mystery. And, of course, I don’t then leave them alone. No, I fiddle and twist, spindle and mutilate, trying to get it “right”.

Technical papers come with page limits, however, so many of these graphs wander around for a while through the land of drafts, only to have their ultimate fate be the rubbish bin of ruthless editing. Some I really like, but they lose out to the necessities of the day. Others were probably never destined for greatness, but served some purpose, like an intellectual scaffolding that helped me build my understanding and argument, but was always going to come down when the construction was finished.

This image combines three of those pieces of scaffolding, freed of their labels and tickmarks, but together as team. I knew all along that these weren’t gonna make the big time, but I needed to plot them to make sure that my intuition about them was (mostly) correct. It was, they served their purpose, and now they’re off to oblivion. Except that I just liked the way these looked, so I joined them all up like little Legos to preserve here on Flickr.

You can think of it as a curvy Mondrian, without being nearly as good :-).

Show me what they really want (and don’t assume it’s the money)

Posted in Computing, Music, My writing, Research, Science, Writing on November 24th, 2007

Langdon and Poli
There’s been much written and said about Radiohead’s decision to let punters name their price when downloading their new In rainbows album. While some of this heat and noise as been quite sensible, much has been predictable tripe about how stupid and naive the band has been. There is some evidence, however, that the band wasn’t so daft, and that their monetary take may have indeed been not to far from what they (as the band) would have seen through traditional marketing channels.

More importantly, though, I think most of this blather totally fails to grasp the more central question: Most bands (artists, writers, open source programmers, etc., etc.) aren’t in it for the money. If you take out the handful that make a fortune (can we please take out the reformed Spice Girls? please?), most people who do this sort of thing aren’t looking to get rich, and many don’t even expect to pay the bills (hence the term “day job”). For them, the value is often much more in being heard (or read or whatever).

As a concrete example, Bill Langdon, Riccardo Poli, and I are considering expanding a chapter we’ve (in fairness, mostly they’ve) written on genetic programming into a full on book. The traditional model would be to find a (science) publisher (which we could easily do), and then have them produce and market the thing. It would sell a few copies, and we’d make a few bucks along the way. That kind of book is never gonna sell 10M copies, however, and we know going in that we’ll never make very much monetarily. But that’s not why most academics write papers and books; if it was we’d be the daftest lot on the planet. (No, don’t go there…)

What we’re after is, in a crude sense, references. Since we’re not going to get rich, we’ll settle for famous (at least in our circles). So we want as many people to read, use, and reference our book as possible, for that’s really the currency of the realm where we live. (And, in truth, that currency converts back to hard cash in complex and indirect ways, through pay raises, increased odds on grant applications, invitations to give talks and tutorials, etc., etc.)

So our intention is to follow a model not so far removed from Radiohead’s (although we’ll probably not get nearly as much press). Our tentative plan is to self-publish using one of the many print-on-demand sites, so there will be a printed, bound copy people can buy; we’ll keep the price low, because we’re more interested in volume than immediate profit. We’ll also give the book away, probably in HTML and PDF formats, to encourage people to check it out, use it, and refer to it, regardless of whether they ever actually buy a copy. We might have a PayPal donation button, sort of like Radiohead’s download for free and pay us what you think makes sense. Or we might not; that’s a bridge we’ll cross when we get there. We’ll do most of the marketing, taking copies to conferences, getting it mentioned on the relevant web sites and discussion groups, and hopefully picking up a fair bit of word of mouth along the way.

I don’t expect we’ll ever see much money on this deal, but I’m quite optimistic that the three of us can put together a book that’ll get used, and that’s the point for us. Similarly, Radiohead’s made enough money on their music that I doubt they’re deeply concerned about a few dollars here or there. They want to be heard and talked about, and they are. Hopefully we can have a somewhat similar experience.

I should also be clear that just because people like Radiohead (or struggling new bands) choose to give away their music, we shouldn’t just write them off as fools and rip them off at every opportunity. We all benefit from their passion, and it’s in our collective interest to support that when we can. That’s part of why I do my darndest to avoid giving money to bands that are already making a ton - they don’t need my support. I prefer instead to spend my money on the zillions of cool, but virtually anonymous, acts that can really benefit from a few bucks.

It’s over (finally)

Posted in Events, My writing on December 25th, 2005

It’s over.

It is what it is,
and not what it could
should
might
be.

The stores are (hopefully) closed
quiet,
empty,
and even Amazon and FedEx can’t save you now.

There’s only the snow outside,
a hot cup of tea inside,
a pair of goofy cats,
and the two of you,
who have given me as fine a year
as anyone could hope for.

Thanks.

Hush! What a beautiful morning!

Posted in Environment, Events, General, My writing on December 8th, 2005

PeeZed was spot on when he said that winter here can be

…a bony old hag with knives in her hands who comes howling out of the northwest. Our snow is tiny little flecks of ice that screams in sideways, and what’s on the ground are hard pans of icy white grit scoured and scored by the wind. We have a fierce kind of winter here, not the friendly scenic kind.

But there are also times, like last night, when she sits quietly through the long night with her brush, covering every twig and branch with the thick hoare frost, and one wakes up to the muted light of the fog and the muted sound of the snow. It makes me feel like singing, if but softly.

So, frankly, she’s a schizoid. You can guess which of these faces is better company when Sub-Evil and I are doing our half hour morning walk to school together!

And while I’m going on about winter, I’ll point everyone to Lance Fortnow’s recent interaction with winter in the South. Having grown up in Texas (and done my graduate work in Austin), I know all too well what he means about whole towns shutting down because of a little ice. It took me several years to really adapt to the winters here in Minnesota. In my early days I used to just stop in mid-lecture and stare out the window, amazed at how much snow was coming down (or blowing by). The students mostly thought I was nuts, but they were patient with the Strange Foreigner, and I’ve learned to cope much better now. Thank you for asking.

In my 14.5 years here, I think that UMM has closed once for a day because of weather, and most everyone regarded that as a mistake. If you’re in town things are much more sheltered from the howling winds than out in the country (which can easily make a difference of 10 degrees F or more to the wind chill), and the distances are just too short to not get out and walk. So we get a nice e-mail from the admins around the time of the first big storm reminding us that, while school is still on, people (students, faculty, and staff) who live out in the country may not make it in, or may make it late, and that needs to be OK. I had three students who had trouble getting back to UMM after Thanksgiving because of the weather (therein lie some great stories, but no time now), but they eventually got here safely and we coped.

Toto knows you’re not in Texas anymore when you get a matter-of-fact e-mail saying they’re closing one of the campus parking lots so they can use it for snow storage…
