School

Green is Good

Nothing like getting the answer right on CAPA your first try. Bonus points (and maybe a prize if I can find one) for the first person to come up with the correct answer to within 3 sig figs. Assume gravity to be 9.81m/s2:
CAPA problem

A block of mass 1.46 kg is attached to a string that is wrapped around a pulley and then attached on the other side to a spring as shown. The pulley is a solid cylinder of mass mp=2.23 kg and radius R=0.4 m (I=(1/2)mpR2). At first the block is held so the spring is unstretched. You then let the block go. What is the speed of the block after it has fallen a distance 0.44 m if the spring’s constant equals 19.5 N/m?

Studying Through the Night

I’ve been studying calculus all night and I’m now just going to bed. My final is at 10:15am, just a few short hours away.

I doubt I could have gone to sleep even if I wanted to, it was to anxious. Might as well study.

But I feel confident that I can get a really good grade on this test. Depending on how many discretionary points I end up with, I need somewhere between a 78% and a 84% to not PRG the class (i.e. I don’t fail the class, but I’m forced to take it again).

MinesBookExchange, v2

Dan, or someone at MBE, sent out this email around 2am:

After a great deal of work and thousands of lines of code, we’ve come up with a new version of the Colorado School of Mines book exchange. This version should be cleaner, easier to maintain, and more effective. Although we’ve tested the site a great deal, we’re sure there are still bugs in it, so please report them by clicking the Contact link on the front page.
The nature of the site is such that we were forced to remove all previously registered books from the site. If you had registered your books with the site, we apologize for the inconvenience, but hopefully this new version will prove more useful. Thank you.

MBE is a really cool project to exchange books at Mines with your peers. I don’t work on it, but Dan (my roommate from last semester) and Matt (my partner in crime and other things) both work on it.

∞ Better

My week just became infinitely better.

How?

I thought there was a Calc Exam tomorrow, but it’s not!

It’s on Thursday!

Time at SAAS

I always like going back to SAAS, to say to my teachers, to reconnect, and to update them on my life (which often includes pluging my website). I usually also try to think back on my college experience thus far so I add something to Melinda’s “Life after SAAS” class. So I stopped by SAAS today.

SAAS is on trimesters, which means that today was the last day of finals for the fall trimester. I talked with Steve Retz breifly. He then promptly called Connor to complain about some parody website on Geocities or something. I chatted with Kathy Johnson about life at Mines. Karen Spector was in, so I talked with her and Canuche Terranella.

I also had a great discusion with Gary Anderson about calculus and physics. We also discused technology in the education field. Gary (finally) got into PHP and is now working with an open source program called Moodle. I also told him about LON-CAPA.

Then I dropped by Mark’s room and chatted with him.

Server Compromised

Stephanie Savage, the VP of The CSM Broadcasting Club, sent me an email last night telling me the server was down. Ryan Goodwin went over to the office to check it out. Nothing doing.

I just got an email from AC&N (Academic Computing and Networking) saying that our server had been “compromised.” I had Goodwin take preventive measures (i.e. turn the server off). He’s going to format it and setup Linux on it.

Seeing as he’s the Linux guru, I’m letting him go for it.
