Victory!!!

Or at least damn good news!

My dad IM’ed me in the office this morning to say that he’d just gotten back from his first major doctor’s visit since radiation treatment ended last month, and he got a clean bill of health. They didn’t see any signs of the cancer in his throat, so now it’s all about regaining his strength after the nasty rigors of the treatment.

They say that if this type of cancer is going to come back, it will almost certainly do so within two years. So now we wait. Today’s report, though, means that however it turns out, going through all that bought him something significant, and that really helps.

Whew…

A muppet kind of smile

A muppet kind of smile, originally uploaded by Unhindered by Talent.

It’s actually been a long, frustrating, semi-icky day due to a lot of problems in our computer science lab. I hate it when our lab doesn’t behave the way it should, and I’m always frustrated when I have to spent numerous hours fixing things instead of getting “real” work done.

Memes-ville: Five things you don’t know about me

Posted in Education, Family, General, Mathematics, Music on February 20th, 2007

Bristles and pages
This is arguably a poorly formed concept since its meaning can vary wildly depending on the referent of “you” but, hey, if Mr. Tozier is silly enough to tag me I’ll play along :-).

  1. I’ll start with something really random and meaningless: I have short pinkie fingers Actually, the fingers themselves are proportional to my other fingers, but there’s something a little off in the bones of the hand and both my pinkies start “too soon” and thus end about a joint short when compared to their neighbors. Its not exactly a big deal, as I didn’t even realize it until I was 13 or 14, when my piano teacher and I noticed it when I kept doing long reaches with my fourth finger insead my fifth. While I’m sharing trivial physical abnormalities, I also have a slightly curved spine, and smaller feet than expected for someone my height. My mother blames it all on smoking enthusiastically during both her pregnancies.
  2. I’ve only considered leaving UMM once since coming here in 1991. As a Reed (math) grad, I had always dreamed of helping found the computing department at Reed. They weren’t kind enough to set something up just as I was coming out of graduate school :-), but did advertise for their first computing faculty a few years after I came here and I couldn’t resist the opportunity. I didn’t even make the interview, but I have no regrets. I’ve been (and continue to be) really happy here at UMM.
  3. Like Bill, I read very slowly, although I think in different ways than Bill. I read slowly to begin with, and tend to do lots of daydreaming and thinking about what I’m reading on top of it. This is one of the reasons I’m a crap citizen of the blogsphere and related on-line worlds. There’s just way too much great stuff out there, and I’m way too slow a reader to stay on top of them. I suspect that’s one of the reasons I like Flickr; I can process a lot of images in the same time it would take me to read a fraction of PeeZed’s output.
  4. Dr. Seuss (and my son) helped me learned to sing. I’d always enjoyed music, but only started singing with any regularity when Sub-Evil Boy was born; it was nice singing to an (infant) audience that was so wonderfully non-judgemental. Reading lots of Dr. Seuss at the same time also taught me volumes about timing and rhythm. While I don’t miss diapers, I definitely miss reading to him every night.
  5. I have an Erdős number of 4. (Go to the Erdős Number Project for more info on how to compute your own Erdős Number.) The cool thing for me isn’t the number itself, but that it was lowered from 5 to 4 by a UMM alum (Nick Hopper) who I did research with when he was an undergraduate with. He went from here to CMU, where his advisor (and co-author) was Manuel Blum, who has an Erdős number of 1. Absolutely one of my highlights of my career at UMM, and I suspect this will be as low as my Erdős number ever goes. Rather remarkable it’s apparently the same as Bill Gates, but I suspect there are precious few other similarities between us.

Spammers sink to new lows

Posted in Computing, Politics on February 19th, 2007

I just got a really amazing bit of spam, purporting to be from an American soldier serving in IRAQ. It’s a standard Nigerian Oil Scam, except here it’s $25M “liberated” from Saddam’s family and a dishonest “soldier” who wants help getting the money out of Iraq.

While I’m no fan of this absurd war, it really pisses me off when people abuse it to make money at the expense of the soldiers and citizens that have to work and live through it all. With our President and his Halliburton buddies setting such a shining example, though, I guess I shouldn’t be too surprised by this sort of spam, however.

It’s hard for us old folks to get it (or teach it)

Posted in Computing, Education on February 19th, 2007

Four heads are better than one
John Naughton had a nice column in The Observer last month about the chronic problems with IT courses for kids. There had been a plan for a new required exam in information and communication technology (ICT) for 14 year olds in the UK, but enthusiasm for the requirement has waned and it looks like it ain’t gonna happen.

The requirement and the exam are sadly typical of so much K-12 tech education. As Naughton put it, these kinds of requirements (and courses) tend to be “An Old Person’s Guide to ICT”:

There’s a surreal quality to it, conjuring up images of kids trudging into ICT classes and being taught how to use a mouse and click on hyperlinks; receiving instructions in the creation of documents using Microsoft Word and of spreadsheets using Excel; being taught how to create a toy database using Access and a cod PowerPoint presentation; and generally being bored out of their minds.

Then the kids go home and log on to Bebo or MySpace to update their profiles, run half a dozen simultaneous instant messaging conversations, use Skype to make free phone calls, rip music from CDs they’ve borrowed from friends, twiddle their thumbs to send incomprehensible text messages, view silly videos on YouTube and use BitTorrent to download episodes of Lost. When you ask them what they did at school, they grimace and say: ‘We made a PowerPoint presentation, dad. Yuck!’

When I came to UMM in ‘91 we had a computing requirement as part of our general education requirements. That was dropped in ‘99 when we converted from quarters to semesters, largely based on an understanding that the state was going to be requiring some sort of computing course for all high school graduates. Unfortunately those high school courses are typically just the nightmare that Naughton describes, leaving the students with little real understanding of the underlying technologies or larger issues, and with a seriously bad taste in their mouth regarding these sorts of courses (a bad taste that carries over to college when we get here).

While I certainly think we need more science, math, and technology courses in K-12, it’s also clear that we need good classes and not misguided exercises in teaching outdated ideas that end up being a really annoying form of babysitting.

I tend to have mixed feelings about Morris dropping our computing requirement. The requirement was certainly good for our program. It brought lots of students through our courses, many of which would probably have not taken a computing course otherwise. Quite a few of those became majors, and those “walk ons” represented a very large proportion of our female and minorty computing majors. Now that the requirement is gone, our majors consistent almost entirely of students who come to college intending to be computing majors, and we get almost no “walk ons”. Consequently, our pool of majors (who I love dearly) is nearly 100% pasty white boys.

My experience with the students here is that they are often very familiar with Facebook and MySpace like Naughton suggests, but it’s by no means universal. I used blogs in my First Year Seminar course last semester, for example, and found considerable variation in the students’ experience with blogging. While many were very experienced, others were still very uncomfortable around the technologies.

Would a computing requirement here help? If so, how? What do our students need, and how do we serve them? And how do we avoid teaching just the sort of courses that Naughton so rightly skewers?

There’s a Carnival of Mathematics!

I just stumbled across the fact that there’s a new Carnival of Mathematics, with their first edition up a bit over a week ago. The next edition is due to be posted on the 23rd on Good Math, Bad Math. Thanks to The Science Pundit for the pointer.

As far as I know there’s no carnival for computing - does anyone know different?

A stem in the jumble

A stem in the jumble, originally uploaded by Unhindered by Talent.

Several years ago I planted some Cayenne seeds in an odd patch of ground that had never been much use to anyone. Much to my surprise, I got a lot of peppers off that, and very spicey ones to boot! Unfortunately, they were arguably too spicey, and we ended up using very few of them because they were just too darn hot for various members of my family.

So there they sat, drying nicely in a bowl in the kitchen. For years. Literally. Many years. Gathering dust.

Finally, WeatherGirl put her foot down and announced that we were composting those little husks and moving on. But before that happened, I just had to take some photos. The first ones are set on the lid of a cast iron dutch oven that I love (but which we don’t use all that often). There’s another neat group posed with an empty lime cordial bottle, but I haven’t had time to clean and post those yet. Hopefully in the next week…

Oh, the irony

Posted in Environment, Politics on February 17th, 2007

I’d love to be a fly on the wall as the Japanese officials and the crew of the Nisshin Maru try to figure out how to deal with the possibility that they may need to accept Greenpeace’s offer to help. If you hadn’t heard, the Nisshin Maru (a Japanese whaling vessel) had a serious fire on Thursday (one sailor was killed) and it appears that the ship may now be immobile. A Greenpeace ship (the Esper- anza) was in the neighborhood specifically because of the whaling activities of the Nisshin Maru; they are now offering to help (evacuating the crew, and towing the Nisshin Maru to a dock), and may indeed be the closest ship in a position to do so.

Japanese officials (and presumably at least some of the crew) have serious misgivings about accepting aid from sworn enemies, and so the Nisshin Maru sits there while people argue over the next step. Given that the Nisshin Maru is very close to, e.g., a major penguin colony, it would almost certainly be a Bad Thing, however, if something nasty like a major oil leak happened while people debated the matter.

One advantage, I suppose, of very publicly doing something pretty unpleasant (i.e., killing whales) is that there will always be people watching, which means that help is never far off if something goes wrong :-). Now they just need to stop their whining and accept the help that’s there.
