On The Simple Things

Tuesday, October 25th, 2005

I was driving my boss to the other building at work, and we went past some trees on a hill by the road. The leaves from the trees had fallen on the ground, forming yellow leaf-clouds in the grass. These leaf-clouds were offset from the trees to which they pertained, implying that there must have been a steady eastern wind when these leaves were falling. Nature has a way of beautifully demonstrating simple mathematical principles. The on-tree leaf-density, terrain height, and wind current, mappings from R3 to R, R3 to R and R3 to R3, respectively, combined to form the on-ground leaf density mapping from R2 to R.

Or, as Adam put it, it kinda looked like the trees had shadows made of leaves.

Sadface

We had a big problem at my Job with employee contact information listing. Microsoft Server has this thing called Active Directory, that stores all kinds of contact information, but in order to edit the thing you have to be logged in as an administrator. In order to sort of get around this problem, we had another directory that was just an excel spreadsheet floating around. If you wanted someone’s contact information, you could check the excel spreedsheet, or look in your outlook contacts, which was kind of related to the active directory thing.

I started looking into this and found a python module that let python connect to Active Directory. After a bit of screwing with it, I got it to work and talked to my boss about creating my own program to access the directory and make changes, so that we could let other people make active directory changes without having them go through us. He said ‘OK’ and I began cranking out code. I’d never done much with Tk so I learned a bit of that, and got started. I had just gotten to the point where you could enter a name to search for, and it would get a list of all the results, when Adam told me he’d found a solution online. It does everything my little program was going to do, but with much more ease and style.

I felt sad as I closed my text editor, knowing I could finish this program but now there’d be no point in doing so.

On Personal Improvment and Escape Energies

Sunday, October 16th, 2005

I haven’t made a decent post in a while, and i’d apologize if I did that sort of thing, but I don’t so I won’t. It’s sort of crazy how fast this semester has progressed; I’m already almost half way through it, and I’ve only got one more ‘fall semester’ after this one. I’m not sure what kind of classes i’ll be taking next semester, but the realization that I can spend the rest of my college career taking only 12 hours a semester is kind of relaxing.

I spent a bit of time trying to juggle today, but it didn’t really work for me. I always give the balls a few tosses, lose control somewhere after the third or fourth throw, and then just give up. Oh well. It’d be nice to juggle, and it does provide me with amusement when I make a few sucessful steps, but the frustration involved in the learning process or enough to make me give up some times. Thinking about it now, there’s a sort of potential energy curve involved with learning things. If takes ‘mental energy’ to learn a process or ability, but once you’ve learned it, you gain a ton of energy because the process can be applied many places.

The point I’m trying to make with this idea is that learning new things is kind of like escape energy in nuclear decay. It takes a certain amount of activation energy to get the beta particle out of the nucleus, but once it escapes it radiates a ton of energy. The same is true for something like learning an instrument. It takes patients and forebearance to learn to play an instrument, but once you do learn to play it all of that patience is payed off in full and then some, because you can derive enjoyment out of your newfound ability to play the kazoo or whatever instrument you choose.

I play the guitar. I’ve played it since the end of my sophomore year in high school, which would be about four and a half years. I haven’t practiced any where near as much as I should, which means I can kinda sort play a few songs, but most of what I do is just messing around in the pentatonic scale. I wish I’d learn some other scales, but the only one I really know is the pentatonic minor so that’s all I play. I’ve been told that my guitar solos have kind of a twanygy, country-blues kind of sound to them, and I guess they do but whattyagonna do. When I started playing the guitar, I wanted to be able to belt out metallica style guitar solos. Wild, fast expressions of my inner temperment and spirit. Squealing, screaming, powerful and hauntingly melodic songs of ghosts and banshees. Instead I can pluck out the humming ditty of a buck toothed guy with a banjo. I mean, I’ll take what I can get, but I could have at least got the groove of a beatnik or something. I don’t even have the slightest southern accent.

High School Math is Difficult

Saturday, October 15th, 2005

I’ve spent a good deal of time today working on a project of mine and it’ve had a heck of a time writing a function that will tell me when two segments intersect each other. It’s tricker than you’d think; you have to deal with cases when the lines are vertical and then there’s other issues as well; it’s easy to do if you’re given a specific line, but generalizing this thing has proven rather difficult. It’s really kind of embarassing, since it seems like it should be an easy thing to do.

Update: Finally got it working, and it wasn’t easy. My god.

Your eyes play tricks on you

Thursday, October 13th, 2005

I started wearing a jacket to keep warm, and I’ve been letting it sit on my chair when I’m at work. This leads to periodic bouts of confusion on my part, because when I get back to my chair from being out doing something, It looks for a second like someone is sitting in my chair. I have to look at it for a good second before I realize that it’s just my jacket. Tricky…

Just What I Needed

Sunday, October 9th, 2005

I managed to break both of my car’s keyless entry things. In the exact same way, too. So I went online to look for a replacement, but found this instead.

Wanted

Friday, October 7th, 2005

I like short saying that are big on meaning. Like “I Owe you a beer.” I started thinking about this after reading an article somewhere, the basic point of which was that precision of language gives you much greater effect if you’re careful about it. When you bump into someone that you know, saying “how are you doing” is pithy and more or less meaningless. “It’s good to see you,” however, is effective and meaningful. It’s a better approximation of the underlying feeling you’re trying to experss to the person – you don’t really care “how they’re doing;” you really just want to express your pleasure in seeing them.

I need such a saying that is capable of expressing my joy and love of the wild and beautiful mathematical complexities of the world. I will have to think about this. I’m sure I’ll come up with something, but I guess any help you can offer would be appreciated. The problem you run into with those short statements is that they can lose their meaning if they’re over used. I frequently pause my thoughts to just think about how cool whatever I’m thinking about is. I suppose its possible that if I had some little phrase that I uttered to myself every time I thought such things, the phrase would become watered down and meaningless. Perhaps I’ll do more for my appreciation by just saying ‘cool, man’ instead of whatever phrase I happen to think of. Perhaps.

Blatant Partisanship

Thursday, October 6th, 2005

Whenever a program in windows crashes, a window shows up, telling you that the program crashed, and asking if you want to send a report to Microsoft. I find that whenever an Open Source program like Firefox crashes, I click ‘no’ because something bugs me about the idea of a bunch of guys at microsoft going ‘oh I knew that firefox thing broke all the time.’ If IE crashes, though, I click the ’send’ button every time. I guess I’m just a partisan hack.

“I Owe You a Beer”

Wednesday, October 5th, 2005

I’ve been told “I owe you a beer” numerous times, by sales guys, after I solved their computer dilmena. I guess if the fiat monetay systems collapse, I know we can at least use booze as a system of currency. I’m not a drinking man, but there’s something about hearing that phrase that makes me feel better than just being told “good job,” or “thanks;” it combines heartfelt appreciation with a manly respect. I submit for your consideration that if your desire is to express gratitude to another man, no better phrase exists.
