Intro

Hi Everyone, This is my own space on the web. My name is Olumuyiwa Oluwasanmi. Well for those of you who find that too much of a mouthful please call me "M". Pronounced the same as the letter in the Alphabet of course. I am currently a PhD student in the Department of Computer Science and a Masters student in the Department of Mathematics at the University of New Mexico , Albuquerque. My goal is to learn as much as possible and get out of school as quick as possible I don't intend to spend the rest of my life in school :) More seriously, so I can begin to make my own contributions to science eh?

My interests are in provably secure, distributed computation and algorithms, partial differential equations, differential equations, programming(I thought I was done with that), Martial arts(Jujitsu) and learning about different people and cultures and lastly finance.

Poetry

The Perfect Woman

Everyday I dream of her eyes so clear,
I can see myself as I truly am
Idiosyncracies, faults and fears,
My wish of how her body is sculpted,
with the perfect algorithm.
The way I imagine our hearts beating,
In a perfect synchronous rhythm.
Being alone with her is a shear joy
As I imagine her outpouring the treasure's of her love,
like layers of sweet chocolate
As our love grows sweeter and deeper.
sometimes not understanding why I seem to get so
obsessed, with the perfection of her faults.
That sweet prison of loving her,
the feeling of knowing you have a beautiful thing locked in a vault.
Looking forward to every quarrel, knowing that our temporary parting North and South, Will only bring us together stronger than ever
because the world is round.
The pain of how much we will ever hurt each other,
Is no match for the forgiveness and comfort we give one another.
Our closeness and understanding so hard to describe,
How we can't differentiate between the thoughts of
one another's minds.
This sweet long conversations we have between our
hearts, that are so loud and clear with each unspoken word.
Who can describe the unimaginable contentment,
pride and happiness a man feels with all of his heart,
knowing this perfect Woman loves him back.
A Man may have pride and sometimes indifference he may feign,
But he can't deny that all he wants is for her love for him to continue to reign.

Some Code in C++0x

Choosing random numbers without replacement

Some coding tutorials

#include <boost/unordered_set.hpp>
#include <algorithm>

#include <boost/random/uniform_int.hpp>
#include <boost/random/variate_generator.hpp>

boost::minstd_rand cgen;
boost::uniform_int<int> cunif(1, 1000); //uniform random numbers between 1 and 1000 or [1,1000] for those mathematically inclined!

boost::unordered_set<int> nums; //use set to handle without replacement
while (nums.size() < 100)labels.insert(cunif(cgen)); //insert 100 numbers without replacement.
