  • college football poll - week 5

    The Beavers continue their rise despite having two less wins than most of the rest of the country (thanks to Hurricane Isaac forcing the postponement of their game against Nicholls State during week one and a bye in week three), this time all the way to the top spot after a win against Arizona.

    Alas, despite being 5-0, Northwestern has yet to reappear in the rankings, as all of its fallen opponents are pretty freakin’ dreadful.

  • college football poll - week 4

    Sad face. My ‘Cats dropped out this week. Since South Dakota is an FCS team, their win doesn’t count. And ‘Cuse, Vandy, and BC keep losing their FBS games, which isn’t helping either…


    Anyway, Notre Dame’s win over Michigan causes them to swap places with Stanford. And how about two-win Oregon State in fourth place? When those two wins are over Wisconsin and
    week 2 number one UCLA, that will happen.

  • college football poll - week 3

    After week 3, we know a little bit more about what’s going in college football. Stanford claims the top spot after beating USC (who drops out completely). My Cats are still in it at #16!


    I love how after only 3 weeks of games, the graph is now connected. Also, very interestingly, Oregon State comes in at #25 despite having only one win… The Beavers beat Wisconsin, who beat Utah St, who beat Utah, who beat BYU, who beat Wazzu, who beat UNLV. If this chain were repeated to infinity, then it would be like Oregon State beat TWO teams!

  • XDG menus in WindowMaker

    For some reason, this took me forever to figure out, so I’m posting it here.


    Let’s say that you, like me, are an avid Ubuntu user who refuses to be dragged kicking and screaming into Unity-land, instead choosing to go completely old-school and run WindowMaker. However, you want a nice application menu. Here’s what you can do:


    Grab the “xdg_menu” perl script from here.


    Run the following code (in the directory you downloaded the file):



    chmod +x xdg_menu
    sudo cp xdg_menu /usr/local/bin
    sudo apt-get install libxml-parser-perl


    Next, open up WindowMaker Preferences, scroll over to the menu-editing screen, and drag a “Generated Submenu” bar over to your menu and rename it whatever you want by double clicking on it. In the “Command” field, enter “xdg_menu”. Save and you’re all set.

    Woot, it’s college football season again! Time for some graph theory meets anthropology computer poll action. Again, early in the season, this doesn’t tell us much as the graph is disconnected. But still kind of fun. Plus, my ‘Cats are in the #12 spot. (I believe they are the only team in the country to have two wins over BCS schools. So what if they’re both 0-2.)

  • TeX synthetic division in Macaulay2

    There might be a small audience for this code (algebraic geometers teaching precalculus!), so I figured I’d put it out there on the internet.


    Let’s say you want to put a synthetic division problem in a TeX document. Let’s also say that you are a user of Macaulay2. You can then use the following code to get the desired result.



    Macaulay2, version 1.4
    with packages: ConwayPolynomials, Elimination, IntegralClosure, LLLBases, PrimaryDecomposition, ReesAlgebra, TangentCone

    i1 : writeSyntheticDivision = (f,a) > (
    x := first gens ring f;
    A := reverse apply(first degree f+1,i→coefficient(x^i,f));
    B := {};
    C := {A_0};
    scan(A_{1..(#A-1)},b→(
    B = B|{a*(last C)};
    C = C|{b+(last B)};
    )
    );
    string := “\\begin{array}{r|”|concatenate apply(A,i→“r”)|“}\n”;
    string = string|"\\cline{2
    “|toString(#A+1)|”}\n";
    string = string|toString a|concatenate apply(A,i→“&”|toString i)|“\\\\\n”;
