Your Home Away From Home

I couldn't seem to find any decent tabs for the songs Jiro plays in Android Kikaider: The Animation (an anime that used to play on Adult Swim a few years ago), so I made up my own.

In Systems Security class, the professor presented us with an interesting homework problem involving random numbers which I thought some of you might enjoy.

According to this page (near the bottom), when Java 1.3 switched from using a native BigInteger implementation to a purely-Java implementation, it gained an increase in speed of "as much as 5x or more." This has led many people to believe that Java's BigInteger class is comparable in speed to the popular Bignum and GMP C-libraries.

While waiting for the completion of the Sunday Polka Worship Service (...) at my cousin's baptism, I observed a number of people making burgers for what appeared to be the upcoming outdoor beer-and-polka festival. The large number of blatant health-code violations aside (including one woman who repeatedly picked things off the bottom of her shoes using her gloves), the one thing that stood out most was how incredibly inefficient they all were. To make a burger, each individual worker (of four) would do the following:

I wanted to see how easy setting up a WordPress blog was compared to Drupal. This Drupal blog took about 16 hours over the course of about five days to set up. WordPress took about 20 minutes, and only because I was really lazy.
I'm going to use the new blog not to replace this one, but to coincide with it - I need someplace to record my more rampant thoughts, the ones that don't quite fit here.
If you're the one person who actually reads this blog, check it out. It can be found here.

Sorry, no post for this week - been too busy with work and posting elsewhere.
I know, I know - you feel like I've been cheating on you. Don't worry though - next week, I'll come home with a nice bottle of champagne, give you a long back-massage, and we can forget this whole thing ever happened.

Until then.

Finally, we get to the point: how RSA encryption works. You may want to review parts 1 and 2 to make sure all that modular arithmetic stuff is fresh in your mind.

Recently, a group and friends and I spontaneously decided to make a game. What kind of game? We dunno. How? Doesn't matter. We just wanted to make a game. Of course, being as wise and all-powerful as I am, I know firsthand that this is easier said than done.

Ah, welcome back my vigilant peons. Today we will be continuing the topic of our last discussion: modular arithmetic. Throughout this discussion, we will assume all numbers are integers.

2. Euler's Φ Function
If you'll recall, the last fun-filled example we gave was to find the last digit of 3⁴⁰³ - we did this simply by noting that 3⁴ ≡ 1 (mod 10) and following some simple logic. Today we generalize this technique.

I'm always really surprised, disappointed, and a bit gassy over how despised anything involving even the simplest of Mathematics is by most Computer Scientists; the mere mention of the word "derivative" is enough to invoke a cringe of repressed childhood-pain from all but the strongest-willed of programmers. However, even if a 'matrix' is nothing more to you than a bootleg DVD you torrented when you were 16, you can still enjoy the limitless pleasure provided by a basic understanding of modern mathematics.
