Another fine showing at Digi-Key

DKC3 2005 logo
Each year Digi-Key (a major catalogue/on-line vendor of electronic components several hours north of here) hosts a very nice programming and problem solving competition for several regional schools. They obviously see it as a valuable computing and PR exercise as they really lay out the red carpet for us each year, including paying for the hotel stay, tons of food, and nifty prizes. A week ago Friday (21 Oct 2005) was our fourth time to participate, and the for the third year running we had a team place in the top three (out of 17 teams). In fact, of the six teams that have competed in the last three years, no team has done worse than fifth and four of the six have place second or third. (The first year we competed was odd because the students had to use a language and programming environment they were completely unfamiliar with.) The action shot below shows the team that placed third: Declarative Non-statement, featuring (l to r) Matt, Scott, Tyler and Jake.

Declarative Non-statement: DKC3 05 3rd place
This year the winning team (from U of M Duluth) blew everyone away with 367 points. The range from second to fourth, though, was only 27.5 points (279.5, 264.5, and 252), and then another big drop to fifth with 195 points. Only 12.5 points separated our two teams, so it was definitely a tight finish.

From a teaching standpoint it’s a nice contest because they mix a lot of different skills and activities (short and long programming problems, word/math problems, engineering puzzles, etc.) so it’s clearly about problem solving instead of “just hacking”. And from a departmental standpoint it’s a cool event because we get money if the teams do well. Every member of the third place team, for example, gets a $100 gift certificate at Best Buy, and the discipline gets a check for $600 – w00t! Last year, when our teams placed 2nd and 3rd, we received $2400 on the backs of our students’ success :-).

Congratulations to both our teams on another fine year! Now we’re in the chaos of prepping for the ACM regional competition. No money in this one, but much tougher competition so more prestige. The top team or two in the region (probably out of over 150 teams) will get to go to the International Finals (in San Antonio this year) in the Spring, which is a pretty sweet deal. UMM had a team make the finals in 1998, and have had numerous teams in the top 20 over the years, so on any given day…

Good grief! The entire Applications folder got wiped!

He always wanted to be a dog when he grew up
Or further reasons why I hate computers…

Sub-Evil Boy got a new computer game while I was away at the Digi-Key competition (more on that in a later post). Unfortunately something weird happened in the install process (we’ll probably never know the details) and it wiped the entire Applications folder on that computer. Everything in it was gone except for about a half dozen application fragments (which I’m guessing survived because he didn’t have permission to remove them). I suspect it was a combination of a poorly designed install mechanism and an honest mistake, but it still sucks.

It’s amazing what a pain it is if Mac OS X loses its entire Applications folder. There are the obvious things like iTunes and a bunch of Sub-Evil’s games, but there are some more tricky bits like, oh, no web browser (so you can’t [easily] download replacements for, say, the lost web browsers) and no System Preferences or anything in the Utilities folder. Argh!

Restoring the apps from the DVD doesn’t do it because that doesn’t give you things like Safari and iTunes and the Utilities. So it looks like I’ll need to re-install the system software, which bites, in part because backing the Users beforehand is a pain with so much missing. We’ve had really good luck with BackupPC in our CSci lab so I’m really thinking I need to install it here at the house to manage the backups of our boxes.

As much as this sort of thing drives me nuts (and sucks up way too much of my time), I figure I at least have some clue how to handle it when it happens. One has to wonder, then, what all the other poor souls do who are just barely getting by. If you’re still nervous about the power switch, I suspect that erasing your Applications folder is pretty much the apocalypse.

Oh, and the picture? Sub-Evil was understandably pretty stressed and worried that I’d get a wee bit upset at him. So I just want him to know that I don’t blame him and we’re all still cool. But if he ever does it again I’m going to make sure this photo (from when he was about 6.5) appears in his high school senior yearbook :-).
