Cover of Tongue party by Sarah Rose Etter

Actually, I helped a piece of Jess Larson’s wonderful art become the central component of a book cover, but let us not quibble.

As patient, long-time readers might know/remember, Jess Larson makes very cool art, including a fantastic series of girdles from several years back. There was a showing of her girdles at the PRCA back in 2006, and I had the chance to carefully photograph the show, posting many of the results on Flickr.

Zip ahead several years, and one of these photos caught the eye of the folks at Caketrain as they were looking for ideas for the cover of a new book they were publishing: Tongue party by Sarah Rose Etter. Some e-mails were traded, etc., etc., and Jess and I both happily agreed to have our work (her girdle, my photo of it) used for their cover.

One of the unexpected little treasures that was waiting for us when we got home from Arkansas this week was my copy of the book, and the cover (pictured above) is really wonderful. I love the texture they added as the background and the way they’ve incorporated the text. I haven’t actually read the thing yet, but the pre-press blurbs certainly sound wonderful and I look forward to adding it to my summer reading list!

Thanks to Jess for making such cool art, giving me such nifty things to take pictures of, and being generous about the use of her art in this new context. Thanks also to the kind folks at Caketrain for seeing the work and getting in touch, and for making such a cool cover out of it all. This is another neat example of the value of sharing work on-line with tools such as Flickr; without that none of this would have been possible. I’m not getting paid anything beyond my free copy of the book, but now a whole new set of people will see Jess’s art and my photography, and that’s quite fine in my humble opinion.

Award ceremony at the 2010 Poetry Out Loud regional, Fergus Falls, MN. Thomas McPhee (on far right) took first.

Thomas qualified for the state finals last year (along with MAHS student Alex McIntosh), so we had the good fortune to attend last year’s event. The quality of the performances was really exquisite, and I highly recommend the event to any fans of poetry and literature in the area.

Tim Ostby (the other MAHS student this year) placed fifth at the regional. Congratulations to him and all the other students that performed last night! While there were fewer competitors at the regional than last year, the quality of the performances was considerably stronger, and the venue (A Center for the Arts in Fergus Falls) was vastly better than last year’s (a classroom at a regional community college).

Thomas McPhee, David Johnson, and Tim Ostby at the 2010 Lake Regional for Poetry Out Loud. Thomas took first, and Tim took fifth.

A huge thanks to David Johnson, drama coach and english teacher at MAHS. Dave’s been a huge influence and support for Thomas in both theatre and Poetry Out Loud. It’s greatly to Dave’s credit that MAHS has had a student in the state finals of Poetry Out Loud each of the last four years (which is every year MAHS could have competed), with two in last year’s finals. Further, every MAHS student that’s gone to state has placed in the top 6: Anika Kildegaard took 2nd in 2007, Mary Hu won the state competition in 2008 and went on to the National Finals, and Alex McIntosh placed 4th and Thomas McPhee 6th in 2009. In fact Morris is the only high school in the state to place four students in the top 6 from 2007-2009, with no other school has placing more than two. Not a bad track record for a small rural high school. Thanks a ton to Dave for all his support and assistance!

• Models of Computing Systems
• Fuzzy logic and fuzzy sets
• Refactoring

I’ve taught Refactoring several times and have a pretty good handle on that. Fuzzy Logic I’ve taught once before and am pretty comfortable with. The Systems course, however, is one I’ve never taught before and am still struggling with on a number of levels, including the textbook.

Any suggestions and ideas on any of these would most certainly be appreciated. I’ll say a little more about each course below the fold for those who want all the gory details.

Models of Computing Systems This is one of our three core courses (the others being Algorithms and Computability, and Software Design and Development), is a 5 credit course (4 hours of lecture and a 2 hour lab each week), and is intended to expose students to computing systems using a layer model that includes as major topics

• Assembly language and a quickie overview of basic architecture
• Operating systems basics, with an emphasis on processes, process management, and threading/concurrancey
• Computer networks
• System administration, including the installation, configuration, and management of common tools like web servers

I’m planning to use x86 assembly for the first item, and the sysadmin work will happen on Linux boxes. I’m planning (still in a vague way at the moment) to try to use computer security issues to motivate/illustrate a number of key concepts in this course. Things like file system and disk structure can be pretty abstract, for example, but I’m thinking that doing a lab where we see how those decisions lead to lots of “erased” data being recoverable might make it seem more “real” and significant.

I realize that no book is going to cover all these things, and on-line resources plus lecture can provide the necessary background for several of these. This course has typically using a “standard” OS book like Silberschatz, et al, but this is large and expensive and really only addresses one of the four topics. If anyone knows of a good book that would touch meaningfully on more than one of these areas, though, that would be really helpful.

Fuzzy logic This is a 2 credit elective course, and should provide a reasonable background in the theoretical definitions and concepts in fuzzy logic, as well as giving the students a chance to apply those ideas. (My current plan is to write robot race car drivers using fuzzy notions of concepts like fast, slow, near, and straight.)

I’m probably more interested in solid coverage of the theoretical material than the applications side. The students will benefit from a good introduction and reference on the mathematical material, and I can probably handle the motivation and application side in class pretty well.

When I last taught this (Spring, 2006) I used An Introduction to Fuzzy Logic for Practical Applications by Kazuo Tanaka, translated by T. Niimura. That book actually worked quite decently. There were some predictable translation issues, but nothing that we couldn’t manage.

Refactoring This is also a 2 credit elective course. I’ve taught this course several times, and I’m likely to again use a combination of Fowler’s Refactoring and Kerievsky’s Refactoring to Patterns. Fowler is the “standard” in the field; the first five chapters of his book are absolutely classic material on the realities of software development and should be read by pretty much anyone who aspires to write good software. Kerievsky’s book builds on Fowler and does a really nice job of demystifying design patterns, converting them from magical insights codified by geniuses into things you could discover on your own through careful refactoring. When I last taught it I think I had Kerievsky as the required text and Fowler as the optional book. Given that together they still add up to less than $100, I’m tempted to require them both. We have lots of copies of Fowler in the lab, though, so I might just require Kerievsky again. Ideas/thoughts on this would definitely be appreciated.

One of the problems we’ve run into in this course in the past has been attempting refactorings on code with limited automated testing. Without good tests you lose your courage to refactor mercilessly, or you have false courage and end up breaking things without realizing it until (sometimes much) later. With only 2 credits to work with, however, you don’t want to spend two weeks writing unit tests for a system before you can start refactoring it, especially when you don’t really understand what the units are and what they’re supposed to be doing. This time I’m planning to use BDD tools like Cucumber, RSpec, and JBehave this time to more cheaply write high level acceptance/functional tests that exercise the key parts of the system in meaningful ways without getting bogged down in a bunch of poorly understood unit tests. We’ll see how that goes.

Wrap-up

So, there they be. Any thoughts, ideas, or suggestions would be greatly appreciated, especially on the Models of Computing Systems course.

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.

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!

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.

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.

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!

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.

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.
