Story of my life

I am the younger of 2 brothers. I was born at midnight on the night of Halloween, 1975. My parents had a choice of birthday - they chose November 1st. I was raised in Yorktown, NY until 1980, when my dad got a job as a professor at Brown University. So our family of 4 moved to East Greenwich, RI. That was about 1 week before I started Kindergarten. My first computer was a TI-99/4A which my parents bought for $50 in December 1983 during the "after Christmas" sale. Ever since then, I was hooked! (If you're really interested in how I got started, check out this long lost newspaper article from our local newspaper in 1984)

My family got me started in programming, but several years later I was beyond their help. In school, I used to love study halls because I would spend the time thinking about code. When my brother went off to college in 1990, my hobby got a bit more serious. I made games such as Kentris, Sibros, and Ken's Labyrinth (my first game on the market) during high school. In 1993, just a month before my first semester at college, I signed a contract with Apogee software to create a new 3D engine called the "Build engine".

My programming wasn't supposed to get in the way of my classes, but I didn't do very well that first semester - I only passed 2 of my 4 classes. So I took a leave of absence to work full time for Apogee. For 3 years I worked on the Build engine. When things quieted down, I returned to college and finished in May 2000.

Since then, I've worked on many projects, such as Voxlap, Evaldraw, and PNGOUT. For a few years, I advised a computer club at my old high school. I am an advisor to a course at Brown called Embedded Systems, where the students design their own gadget and (given time) program it. In 2005, I co-founded Ardfry, which sells PNGOUTwin and a few image codecs. In 2013, I joined Voxon as a founder, where I've been working on the Voxiebox SDK and demos.

Everyone in my family works in a technical field. My dad is a professor of electrical engineering at Brown. My mom works at GTech, programming mark and character recognition for lottery tickets. My brother started his own small company, called Advanced Systems (That's what "advsys" stands for) and now he's a technical director at Atrion Networking.

Interests/Hobbies

Computer programming. Favorite optimization: "sub eax, 128" -> "add eax, -128" Think about it. Or not.

Collecting maps: I can draw the borders of all U.S. states from memory. I used to draw maps for fun in elementary school.

Solar energy: Bought a 1kW photovoltaic system from Solar Works. See how much power they're producing: SILVMETR.ZIP (105,581 bytes, 03/24/2005) Also check out the panoramic graph on this page.

Astronomy: I look(ed) forward to waking up early on June 8, 2004. Play with my GLOBE simulator to find out why. Ok, it's the transit of Venus! Using a pair of binoculars and a card to project the image on, I managed to get this lovely photo. Venus is the small notch on the right - probably already on its way out. I realize the camera was at an angle.. I would have gotten it right if I had 3 hands :) Anyway, if you feel like calculating AU with this, I can say the photo was taken at 7:09am EDT (Sorry, I don't have seconds) and at 41.6611°N, 71.4845°W. So there's my lousy contribution to science! :) P.S. good luck!

Geometric puzzles: Rubik's cube, mazes, you name it - they all make great programming projects.

TV! You just can't escape it in our family.

Piano: I can play just about any song I've heard. People say I have a good ear.

Music: Besides my own, I like to collect TV theme songs and anything by Weird Al Yankovic.

Sports: volleyball, bicycling, ping pong, softball, juggling, cubing, cubing while bicycling.. :)

Stikeout

Other cool S T u f ...

(03/06/2000) I plugged my name into Yahoo's search engine and I found some really neat stuff! Apparently, somebody spent the time to write a colorful review about my site. Sounds to me like this fan has a serious case of jealousy!

Continuing with my tradition of shameless self-promotion, I found something else which blows everything away: This quote from John Carmack. I am truly honored that he would pick me out of a crowd like that!

(07/11/2000) I found another quote from Carmack.

Web Site Update History:

Friends' sites:

Jonathon Fowler On 09/12/1999, he simply wanted to greet himself. A year later, when I released the Build engine source code, he jumped all over it. It was his destiny to do a port to modern OS's. When 3DR followed suit with the Duke3D code, I worked with him to add bells & whistles. Jonathon also used to host the forums for my site.

Tom Dobrowolski On 11/11/2000, he just wanted to say 'hi'. A year later, I impressed him with some Voxlap screenshots and we've been in regular contact ever since. Tom and I have collaborated on many projects, most notably the Voxlap Cave Demo. Today, his interests include automatic world/model generation and creative user interfaces.

Dennis Radon On 06/02/2001, he asked if I liked fan mail. Dennis has been very supportive over the years.

Jan Lonnberg On 08/29/2002, he wanted my approval for his port of Ken's Labyrinth. He did a great job with it.

Ben Jos Walbeehm On 11/05/2002, Ben Jos was wondering how KZIP worked. We started out as competitors. More recently, we collaborated on Rubix. He always told it like it was, and never ran out of things to say. Sadly, he passed away in 2013 and his website is now gone. :-/

David Blake On 04/14/2005, he was already thinking about commercializing my projects. Less than a year later, we released PNGOUTWin. David has a knack for the software business, and I look forward to producing more with him.

Peter Houska On 11/07/2005, he called himself yet another fan. Look through his projects page, and you'll see that he's a lot more than that. While similar in look, Peter comes up with his own tech.

Robert Rodgers On 04/04/2006, he introduced himself as my 'humble servant'. Humble is right. Robert has accomplished a lot so far. He reminds me of myself when I was in high school. I have my eye on him ; )
