I work at a small software company that I started with my brother. We make data visualization software during the day and laser controlled video games at night.

Marshie Attacks - Halloween Project

Sunday November 04 2007, @06:00PM
First Person Shooters (Games)
If you came to my house for Halloween this year the first thing you noticed was 18 inch tall green vampire marshmallows moving around on a 8 foot tall screen hung from the garage door. The next thing you noticed was that a laser assault rifle was placed into your hands and you were commanded to kill Marshie for candy. Ok, by laser assault rifle I mean a laser pointer put into a bunch of PVC, but it looked pretty cool. When a dot appeared on the screen it was detected by my iSight camera and Marshie exploded. If you're interested there are more details including a movie posted here.

Pete Ashdown, geek candidate, needs your help

Senator Barbara Boxer is giving away free money to candidates that are challenging incumbents. The catch is that you have to vote for who you want the money to go to. Pete Ashdown is not only running to unseat Senator Hatch (enemy of geeks everywhere) but is tech savvy himself, given that he is the founder of Utah's oldest ISP. His positions on tech issues should be of interest to many a slashdotter. So if you have a moment, click on the link below and vote for him to get some free money.

Vote for Pete Ashdown.

CleanFlicks should be championed by /.

WalMart and the illusion of low prices

Friday November 25 2005, @08:45AM
User Journal

I have now entered WalMart three times in my life.

Before I go on I should mention that I really don't have time to be shopping today. I am moving today and tomorrow. I have other things to do.

Yet I was a WalMart today at 4:10 am. The prospect of a $378 laptop was too much to resist. There were about a hundred people in line in front of me. Assuming that they didn't all want a laptop I figured that I would be ok.

Wrong.

First, the line got mysteriously thicker as time went on. There were easily 300 people in front of me when the doors opened at 5:00 am. This does not include the people that stood in the parking lot and simply sprinted at the door when it opened. What kind of jerk do you have to be to do that?

Second, they put the laptops in the grocery area. At least this is what I was told. I never saw a laptop box. I went to the electronics area which was a mob scene but lacked laptops for some reason. According to a helpful WalMart employee, the laptops were gone from the grocery area before I got into the store anyhow.

Now if you claim to be selling a sub-$400 laptop but can't/won't sell anywhere near as many as people want then you really aren't selling such laptops. You are simply claiming to. Maybe if they offered rainchecks I would believe them, but they don't and thus I am convinced that it is a scam. Classic bait and switch.

I walked out of WalMart at 5:10 am vowing to never return. Unless they will give me a raincheck, which isn't going to happen.

iTunes Vizualiztion - First Draft - Mac Only!

So I found the Apple iTunes developer stuff. Contrary to what I remembered it is free to download the API for iTunes. While they give you working code, it is pretty ugly as far as being a visualization. I have hacked it a bit to get a feel for it and have re-implemented the effect that I created way back when by rewiring an Apple // monitor and running my the wires to my stereo speakers through the coils.

So if you have a Mac you can see it. This similar to the WinAmp viz I posted before, but this version is much better. It scales properly and is green on black. Grab it here:
http//www.angelfire.com/games4/anirak/iTunesX_Visualizer.bundle.zip

As usual, unzip the file and place it in the user/Library/iTunes/iTunes Plug-ins/ directory.

If the direct link doesn't work, there is a link in the "links" section towards the bottom of this page

As I put more effort into this I will probably make a page for it, maybe on a .mac account. We'll see what happens.

Edit: corrected second link. It is probably the one to use.
