My life

A not-so-brief summary of my life:

My father wanted my sister and me to go to medical school.  We moved from Columbus in the summer of 1980, to Scott County, and attended IUS in New Albany.  We were both accepted to IU Medical School in 1984, but I disliked it so much that I dropped out.  I went back to school to study computers while running a bit of software business on the side, mostly writing video games, and got my first major job at a database company in Lafayette, Indiana in 1988.  I got a different database job in Indianapolis in 1991.

I lost my father to suicide in 1986.  He suffered from depression.

I wanted to program video games.  After searching nationwide, I got a job in Salt Lake City in 1993 programming video games.  It was a demanding job and they tended to work us to death, so I switched to a different company in 1999, a small video game startup in Sandy, Utah.  

In the fall of 2000, the second company went out of business, so I went looking for work.  I found a major military contractor in Salt Lake City that did satellite communications for military drone aircraft.  Their business spiked in a really big way after 9-11.  I worked there until September 2014.  Their business had contracted mostly due to cutbacks by the Obama administration, so they had major layoffs.

I loved living in Salt Lake City.

I had saved and invested enough that I retired at age 54.  In 2015, I moved to New Whiteland, Indiana.  In 2018, I moved to Columbus, returning 38 years after I left it.  That was always my plan.

My sister has been practicing medicine for around 34 years.  She lives in Russiaville, Indiana, just outside of Kokomo.

My mother has had cancer for 22.5. years.  At age 82 she has had more difficulty with the cancer but she is for the moment doing okay.  About 14 years ago she married Paul Belding, a nice man who is 85 years old.  They live in his home in North Vernon.  One reason I moved back to Columbus was to be closer to my mother, especially with her illness.

I was always interested in chess.  I barely qualify as an "expert", which is one category below "master."  I am officially 28nth in the state of Indiana.  In Utah I was 9nth.  I served for a while as the vice-president and then president of the Utah Chess Association.  I helped run state chess tournaments right up to the time that I left Utah.  

On moving back to Indiana, I started the Greenwood Chess Club.  I ran a chess club in Salt Lake City for 22 years.

Loss to Novag Super Constellation level 1

Back in 1984, the Novag Super Constellation chess-playing computer was one of my favorite possessions.  I doubt that many of these machines would still be working because the model is almost 40 years old and old capacitors tend to go bad given enough use.   

In 1984 the USCF gave the Novag Super Constellation a rating of 2018 which has been somewhat controversial.   Most online sites today claim that its actual strength is in the 1700s, which I don't believe.  I remember it being much better than me and I was rated in the 1700s at the time.

There was a golden age of chess-playing computers that went from about 1982 to 1995 before most people owned a PC and the only way to play chess against a computer was to buy one of these devices.  Once people bought computers, the market for chess-playing computers almost completely disappeared, although recently there has been a bit of a resurgence of chess-playing computers.  Also, playing chess on mobile devices has become very popular.

Since I am curious about everything, I have wondered for years how I would fair against the Novag Super Constellation today because I am now rated much higher.  I even considered trying to buy an old chess-playing computer on eBay, although not necessarily this model because there are much better ones that came out later.

Recently I found a way to play the Novag Super Constellation using emulation on my computer.  Although I did beat level 1 once, I have lost a few games too.  I'm not quite comfortable playing the simulated chess machine because graphically it is not as nice as playing a modern chess program, plus you have to move the computer pieces as if you were playing the real chess computer which is slightly distracting.

The computer proves that it does not miss tactics on level 1 where it averages 5 seconds per move, which is speed chess.  I think that it would crush most Class A players at speed chess.  This is impressive for an 8-bit 6502 processor running at just 4 MHZ.  It shows that you don't need much computing power to see 3 moves ahead, which is maybe enough to outplay or equal average tournament players even at tournament time controls.

I have set up positions to test the device, and I found that its playing strength only improves marginally as you give it more time.  The Novag Super Constellation seems to be optimized for 5 seconds per move and it plays pretty strong at that level.  One reason is that it has a very good opening book allowing it to reach strong positions out of the opening.

In this game, Stockfish analysis agrees with my opening moves up to move 12.  By move 20 it thinks that I am positionally crushing it, but it is not clear to me at all why it thinks that I am 4 pawns ahead.  I need to do more analysis.  On move 21, I blundered, unfortunately.  If I can avoid making these kinds of obvious tactical mistakes then I likely would beat the machine on level 1.  Once I fell behind, the computer showed no mercy and proceeded to crush me.

Fire Tablets

Right now Amazon is selling some of their Fire Tablets at half price. Although they are budget tablets, not nearly as powerful as iPads, I am pretty impressed with the value for the price.

I have argued that if you have a good smartphone then you might not need a tablet, but I have enjoyed my Fire Tablet while traveling. They are more useful if you subscribe to Amazon Prime.
