MatLab

    MatLab is an extremely versatile program, it’s actually almost like another computer programming language.  It is far, far easier to perform arithmatic operations with it than FORTRAN.  It’s especially good at matrix operations.  Just type in the matrix, and off it goes!

    Naturally, this program has replaced FORTRAN as the bane of my computing existence.  Lines of code that work fine on the professors computer don’t run on mine.  The controls toolbox seems to be installed on my computer, but the control functions are recognized as variables, not operators, when I try to use them.  I’m sure there’s a very simple explanation for all of the problems I end up having.  Maybe I just need to upgrade from version 6.0 to version 7.1. 

    Why is it that spending several hundred dollars always ends up being my solution to my computer problems?

 Update:  Apparently you can type ‘ver’ in the command window and MatLab will tell you what toolboxes you have installed (or you can uninstall it and the first menu page also lists the uninstall options, including toolboxes).  As luck would have it, I don’t have the toolbox I need.  It looks like I get to pay for an upgrade.  Great! Just what I was hoping for!

Circumnavigation

    Yesterday marked yet another sort of "first" for me.  I flew from Tokyo to Frankfurt.  Since that flight goes over Russia, that means I’ve finally at least been a passenger across the entire globe.

    I know my Father-in-law has done that more than once.  As a matter of fact, his circumnavigation has included stops in Australia (and possibly South America).  I still have never been to the Southern Hemisphere.  I hope to correct that travel deficiency in the next three years or so.  

    Anyway, it was another small milestone to celebrate, and that’s always nice.

Technology Update

    I just watched a class live via the Internet.  Then I called my brother, grandmother, and uncle via VOIP.  

    If you’d told me that you could do any of these things at all ten years ago, I’d’ve thought that was really cool.  Today it’s just another routine achievement that thousands of others have done.

    What made this particular event special was that I did this all from my laptop in my kitchen.  Wireless is definitely the way to go!

    My wireless router is connected to the Internet via fiber-optic.  I just downloaded that class I watched in under four minutes.  It was about 62 MB.  DSL used to take anywhere from 20-45 minutes. 

    Life is good!

A Rip in Heaven

    I took a little time to read A Rip in Heaven, by Jeanine Cummins.  Jeanine did a wonderful job relating the story of her family as they dealt with the assault and murder of her two cousins, Julie and Robin Kerry.  This was of enormous significance to me.  Julie, Robin, and I were all students in high school together.  Julie was the only junior in my trigonometry and pre-Calculus classes.  Robin was in my French class.  They were really good young ladies, and I think about them often, even though I had neither seen nor spoken with them after I left high school. 

     One of the reasons I’ll always remember Julie (and I’m pretty certain she never knew this) was because she was the first girl who ever asked me for a date. 

    Julie, Robin, and their cousin Tom were out on the Chain of Rocks Bridge in St Louis on Thursday, 4 April 1991.  They encountered four men, Marlin Gray, Antonio Richardson, Reginald Clemmons, and Daniel Winfrey; these boys attacked the girls and eventually pushed them into the river and forced Tom to jump.  Tom survived, and after a brief debacle during which the St Louis Police accused Tom himself of the murders, they eventually were brought to their collective senses and found the felons responsible.  The trial results:  Antonio Richardson received the death sentence (later commuted to life without parole).  Marlin Gray was sentenced to death (sentence was executed on 26 Oct 2005).  Reginald Clemmons was sentenced to death and still appears to be on death row.  Daniel Winfrey was sentenced to 30 years in prison as a result of a plea deal, and has apparently apologized and will be released in 2007. 

    After the murder, I went through a little period of private rage.  I remember hearing the story on TV in the middle of the day.  I leapt into my car and sped down to the Mississippi, stopping probably less than a mile upriver from where Jeanine’s cousin Tom climbed out of the river about fourteen hours prior.  I don’t really know what I’d hoped to accomplish, I suppose I meant to search the riverbank and scout out the shore of Mosenthien Island as best I could.  It was useless.  All I got for my trouble was some jeering by some 25-somethings who laughed as they shouted at me "What are you doing, trying to find a body?" I let it pass, and just left the area. 

    I left the area, yes, but I didn’t stop quite yet.  I started doing some flight planning.  My mission the next day was going to be to fly my own search-and-rescue.  My Dad, who absolutely hates flying, offered to come along and bring some binoculars and a camera.  I was actually pretty moved by that gesture.  In any case, the next day it was too cloudy for me to fly legally.  Despite the fact the aircraft owners knew what I meant to do, they wouldn’t give me the keys to the airplane.  In retrospect, they were probably right.  All I would have done would have been to violate a lot of flight laws, which would have cost me my license and them their airplane. 

    I was left wishing for the next several years "If only I’d happened to be out there on the bridge with an assault rifle. . . ."  I’d been to the Chain of Rocks Bridge one time, so there was little imperative for me to go, it just wasn’t something I felt like I ever had to do, especially since I’d done it once.  Also, I didn’t own a gun, so wishing I’d been out there with one was just that–wishful thinking. 

    Although I already knew most of the details of the case, it was really good to learn what Jeanine and her family went through.  I wish I could have helped them in some way.  All I can think to do is recommend you buy her book.  (Click here for a link to Amazon.com.  Click here for a link to Barnes & Noble.com).

Newton

    Sir Isaac Newton is at once something of a hero and the bane of my existence.  My latest problem has me trying to use integration by parts of natural exponentials and trigonometric functions.  The last time I had to do this in earnest was 1994 (if that late).  In a way it’s been fun going back and re-learning all of the Calculus and differential equations I’ve forgotten.  On the other hand, it’s time-consuming to have to go back and look it up, and it causes my homework to be late more often than I care to admit.  

    If anyone in a small town called Rolla runs into a guy named Wyatt, give him a hearty handshake for me! I don’t think I’d’ve figured out that one problem without him pointing out what example to follow!

Please Help Me Find My Friend!

    If any of my readers are in the vicinity of Bishkek, Kyrgystan, please be on the lookout for Maj Jill Metzger — She’s been missing for a couple days now.  Report anything suspicious to AFOSI or Kyrgyz police. 

    Story on CNN.com

    Story on FoxNews.com

    Story at AF.mil

     If you have friends, family, or acquaintences over there, please contact them and ask them to be on the lookout for Jill.  If they see her or know anything, pass that information along to US forces or Kyrgyz police. 

    Jill and I were stationed in Germany together about five years ago.  She’s a good troop, and she’s not the type who’d just ‘Up and run off,’ if you take my meaning.   

    I pray to the Lord she’s alright, and that she gets back to Manas safe and sound quickly! 

Update:  According to Kyrgyz police via CNN.com, Jill was not kidnapped.  

8 Sep Link Update:  I spoke to a friend from Kyrgyzstan and her husband who was once stationed there.  Elena has called her family and friends and given them a "Be on the lookout" request.  According to her husband "Money talks in Bishkek."  What I hope someone can do is establish a sort of reward program for information leading to Jill’s safe return.  This will obviously require some detailed coordination in Bishkek.  I’ll keep everyone posted if we can make this happen, or if we hear it’s been done already we’ll pass along relevant information. 

    There’s not much to report on the case itself.  The story is making it into the press, but little overt progress has been made on the case.  Link to AF.mil.  Another AF.mil.  Link to the Post-Chronicle.  Link to Raleigh News.net.  Link to WRAL.com.  Link to Boston.com.  Link to Yahoo! News.  Link to Townhall.com.  Link to Military.com (discussion forum available, registration required).  Link to Air Force Times.com
