The University of Akron’s computer science club has been invited to compete at Case’s Engineers Week in the Lego robot competition. They normally compete against high school kids, but in 2006, they have invited the local area colleges to come in and compete as well. Trick is Case has Lego kits. Each team gets the same exact kit and has to build a robot which searches for a light source. Once found, it must go to the light source to score a point. Two robots go at it at a time. Another trick is we don’t have ANY of the robot gear Case has. All our testing and development will be based on wild guessing. Later on, we’ll get a couple hours to play with the equipment and then we’ll build on the day of the event. Oh yeah, the gear they’re using had cost $800 back in the day. Today, you can’t get it and what you can get costs $400. Its cool stuff, but out of all of our budgets.

After talking with a friend of mine who graduated from Case, I’m thinking we don’t stand much of a chance. They’ve been doing the robot thing on some level for probably at least a decade. Akron? I think they JUST started offering a robot course not too long ago.

The cool part is I think I have some tools for figuring out the light sensing (anyone remember back when I had wired up my apartment?). We need to be able to measure light, identify the location of the light and instruct hardware to move towards it. Doesn’t sound too bad, but the arena will not be perfectly dark and we have to be able to lock onto an 80 watt and 20 watt bulb (if I’m remembering correctly).

J2ME (Java 2 for mobile) has had me curious. I have a J2ME friendly phone. I’m doing Java in DSA2. It can’t be that hard to write something for the phone, can it?

Turns out it really isn’t too bad. The bugger of it is fiddling with the right mix of software development kits and Eclipse’s Java settings. The other fun part is figuring out which SDK matches with the Nokia 6600 phone (for those wondering, its Series 60, v2 FP1 (feature pack 1)). I lost a good amount of time just trying to figure that one out.

But the development process wasn’t too bad once Eclipse was setup to compile and package. I haven’t mastered the art of persuading the emulator to run from the “run program” button, but I found I can use Nokia’s Eclipse add-on buttons to run the emulator from there.

The last thing to try was to actually write something to run on the phone. What better test than the current programming assignment (due this coming Monday, but already turned in). I had to water down the code since the phone lacks a lot of the features the desktop edition of Java has. Once I put together the interface, the rest of the Java class files just dropped right in with a little bit of tweaking here and there. Here’s some screen shots of the Slicing Floor Plan from my 6600:

Feel free to browse the code. I don’t know if it’ll work on other J2ME gadgets. If it does, great!

Just like the desktop edition.

The slicing floor plan has been posted on the site. I also posted the code to the Hexagon assignment. All of it can be found under the Data Structures 2 section.

Duh.

I remember using U. Akron’s dialup to ditch AOL dialup back in the day. I also remember using UA when I was in a jam at a network client site and needed a driver for something.

Now, I’m able to use the UA dialup numbers to allow me to go mobile and maintain a ‘net connection when wifi isn’t available (*cough* Tri-C). I just persuade my notebook to talk to my cell phone and have it dial out. This solves the problem of getting stuck with T-Mobile’s Internet plan for $20 a month (ouch).

One setback (not counting the fact its a low speed connection): the UA dialup account is only good for when you’re a current student. Good motivation to keep taking classes, right? This is one of those “you know you’re a geek when…”

The University of Akron is considered the THIRD most wireless college in the US. It was beat out by Ball University and Western Michigan University. I’m surprised to see Case at number 8. Although, they do have super crazy high speed ‘net access over there which I doubt is wireless friendly.

I’ve posted my Java assignments. You can find them on the school page (scroll down to Data Structures and Algorithms 2). I’ll post them as I complete them. For safety though, I won’t post the code to an assignment until after its been graded.

The hexagon fractal assignment was rather fun. Learning Java Swing wasn’t as bad as I thought it was going to be. Figuring out how to draw in a JPanel took a little bit of work (as I learned, simply drawing on the canvas is sort of a no-no since Swing components will overwrite the canvas every time). You’ll need Java 1.5.0 installed for the applet to work.

Olessia and I were invited by my Russian prof to come in and speak to two classes. Olessia showed pictures when she was in Moscow this year as well as pictures her sister took in Siberia (there’s new pictures in this album as of last week).

The Moscow pics were great. People really enjoyed the TGI Fridays pics. The Siberia pics were great. There were a lot of “oohs and ahs” from the audience. We worked on reading some of the signs. We learned a little bit about the largest fresh water lake in the world. It was great stuff (and I learned a bit too!). Plus, it was great saying the pictures displayed nice and big taking up a good part of the classroom wall.

Its понедельник (Monday) and its going to probably be another busy week of work and school. I have some other news which I’ll post later which will explain the delay in getting the news up on the site…

I’ve started school already. Russian, I think, is going to be fun. The prof seems to be pretty excited about the language and is happy teaching it to us. Olessia helped me with my homework yesterday. It was simple exercises to practice writing a select few of the Russian letters in cursive. We practiced the sounds too. Olessia realized I knew almost all the letters to spell Murzik in Russian (she made me spell it!). Since I know how to spell Murzik, I know how to spell purr in Russian too! Its simply the “mur” in Murzik. And what’s also cool, is if you properly pronounce “mur” in Russian, it sounds like a cat purring. Kpyto! (means “cool” in Russian which sort of sounds like krewto)

DSA2 is going to be cool. Sadly, we’re not allowed to use a notebook or other gadget in class. Apparently too many students abused this privilege by playing games and such and the prof had enough. I guess the good thing is I don’t have to lug 7lb of computer gear in my backpack. The bad thing is I’ll have to decode my handwriting!

Here’s some freaky stuff about the two classes:

My Russian class only had 5 students on Monday! Of the 5, there’s another Rob/Robert (but don’t call me “Bob”) in the class. Rob, in Russian, means slave so I don’t think either of want to go with that. In my DSA2 class, there’s maybe 20 students. In there, there’s 3 Robs! My prof for DSA2 is also learning Russian this semester.

Now the one part that had me worried about DSA2 was the use of Java. See, I survived intro to computer science and DSA1 by using C++. It was the language of choice back then. But now the university has switched over to Java. Luckily for me, this is the class is made up of 50% C++ coders and 50% Java coders. This is also the first time this prof has taught Java. Hopefully she’ll have some mercy for us C++ coders. Sorry, but I won’t be able to post the class notes up. I’m not sure if I’ll post the programs.

Ack!

The Monday schedule:

Go to work (way early)

9-10:30am: Beginning Russian 1 (Tri-C)

Go back to work (maybe grab brunch along the way)

6:40-8pm Data Structures & Algorithms 2 (U. Akron)

Home!

I hope to take notes electronically in the DSA 2 class. If so, I’ll be posting them here on the site.

Continue reading “Back to school”

Whoa! I’m taking a computer science class for once! I’m taking a break from the calculus (just have to take calc 2 now). Data Structures & Algorithms II, the saga continues. When I took DSA I, it was all in C++, which was really nice. Now its in Java, which should be even better but I haven’t coded Java in a class environment so this should be interesting.

Also, I’ve registered for Beginning Russian I at Tri-C (also known as Tri-High, Tri-Again or something like that). Russian is offered at Kent and CWRU, but Kent is at a goofy hour and a pretty lengthy class. The class at Case looks pretty intense. It too is at a goofy hour during the day. U. Akron doesn’t even offer the class. Tri-C offers it as an evening class, but its the same time as DSA II. So, I’ve managed to persuade work to let me out on Mondays, Wednesdays, and Fridays.

Learning two langauges in 15 weeks – this will be hectic.

Oh yeah, Computer Science for Life! I finally had a chance to listen to MC Plus+. Great computer science tunes!
