The thoughts and goings-on of some programmer dad.

From the Orlando Anime Festival

Yesterday, we (Ryan, Tyler, and I) had the pleasure of finally attending my very first convention (outside of the local county fair). Sadly, it wasn't a sci-fi convention as I would have liked, but an anime convention. I don't consider myself to be an anime nerd, and even border on disliking the genre entirely, but I did have a pretty good time none the less. The convention itself was fairly small in comparison to others, but there was still a goodly amount of things going on and plenty of dealers peddling their anime related wares.

The atmosphere or the con was... nerdy. Even so, I felt strangely out of place as I was one of the few attendees that wasn't cosplaying. Most of the costumes I didn't recognize, but there were the likes of Phoenix Wright, Yuna, Link and, surprisingly, several Snakes from Metal Gear: It still surprised me just how many girls were there. In fact, I'd say the males were outnumbered by quite a bit which, for me, is an unusual situation to be in seeing as I go to school overflowing with testosterone. Just being around all these people was probably the most entertaining part of the day.

One of the areas we spent the most time in was the dealers floor. Just about anything anime related was being sold. Mangas, DVDs, T-shirts, action figures, plushies, costumes, weapons. And that's barely scratching the surface. As you can see in the picture above, I broke down and bought a Godot shirt. I wubs it!

There were some video games, including an NES championship tournament, but it was a side to everything else going on. There were rooms showing animes, people talking about how to improve your AMV/drawings, all sorts of crazy stuff. We wound up the night by sitting in on the "Weakest Geek" game show. It was kind of like Double Dare (sans the mess) and a quiz show with the Who Wants to be a Millionaire music playing in the background the entire time. The biggest part of this game was the "Box" game wherein a picture of an action figure would be shown and the player would then proceed to try to find said action figure in a fish tank filled with more action figures and packing peanuts. It was all rather entertaining to watch and the crew running the show was pretty cool.

I'm going to wrap this post up with a video I took while I was there (and later added music to). youtube video

Speed Cubing

One of the more mundane things that happened over Christmas break was my learning how to solve the Rubik's cube. My ability to do so was actually big thing in math class the following month. Since then, I've been improving upon my technique and now I'm going to show you how to solve Rubik's Cube in ten seconds or less. Video after the break.

Awesome Video of Errata

Now, I realize that the "system specs" spewed forth in the above video were probably intentionally skewed so as to follow the whacky, 80s style zaniness, but as an uber nerd and somebody who's intimately familiar with NES hardware, I feel compelled to correct their errors.

Claim #1: 3.58Mhz video core clock speed The NES video processor, a Ricoh 2C02 "Picture Processing Unit", or PPU, is actually clocked at 5.37Mhz. The CPU is exactly one third of this, or 1.79Mhz. The figure they're quoting is the timing of a color NTSC signal.

Claim #2: 240x226 resolution The PPU actually worked with an internal resolution 256x240, though most old TVs did not display the first and last eight scanlines effectively making the resolution 256x224. This was the same for both NTSC and PAL models.

Claim #3: 16 sprite pixel depth I don't even know where to begin on this one. Firstly, the NES had enough sprite RAM (object attribute memory, or OAM) for 64, 8x8 or 8x16 sprites. Secondly, every sprite could have three colors (four if you include transparency) from a palette of 53 colors. Every scanline could hae a maximum of eight sprites, and when this limit was exceeded some sprites were not drawn causing the infamous flicker. Finally, you could have a total of 25 colors per scanline. What the hell they were talking about to begin with baffles me, but there were no 16s involved there at all. Except maybe that internal 16-bit PPU register that could be written to through dual writes to address $2006....

Claim #4: NES has a Zilog Z80 processor This one's easy. The NES did not have a Z80. It had a Ricoh 2A03, which was a 6502 without decimal mode and a set of sound instructions. The Gameboy, however, had a Z80 and the Sega Genesis used one as its sound processor.

Claim #5 It's an 8-bit system Well, that's about the only thing they got right. Though, the system did have a 16-bit address bus....

Well, I'm finished. I'm sure somewhere God has smote a kitten for my nerdy rantingness, but it had to be said and I said it. Caio.

It is the eve of the beginning of my PHP/MySQL class. Of course, we should all know by now that CMS programming is child's play for me. However, seeing as my final project for this class is a CMS with front end, I'm taking this opportunity to redesign stuff, and by stuff I mean everthing (even beyond the site itself). Some things to expect from the next iteration:

  • Twitter integration on blog page
  • A proper portfolio
  • Accross the board branding
  • Page navigation
  • Probably more as I think of it

If my rebrand goes as well as I hope, I shouldn't be updating the design for some time. Geez, we haven't heard that before, have we?

Mograph - now with more 3D

Over the last couple of months I've been served a delicious helping of 3D stuffs at school. This was, of course, overshadowed by the awesomeness that was Flash. But I digress. At the end of this month our final 3D project wound up in an awesome culmination of 3D animation and my favorite motion program, After Effects. The result? See for yourself.
