Jeff's Quotables





"Identify something said to be impossible.
  Determine why THEY think it's impossible.
  Change the rules to make it possible.
  You have an invention!"


 Sharing Credit 

"Credit multiplies; It doesn't divide."


 Artificial Intelligence 

"AI is defined by experts as machine emulation
of the human thought process,
they would be better off first emulating the
thought process of a chicken."



"Engineers have an advantage over the rest of the population. We know how things work and they don't"



"Fair is a four letter word."



"It is said that you learn from your mistakes.
It's better to learn from the mistakes of others.
More quantity - Less pain"


Global Warming

"Global Warming? At least not in Bridgeport CT."



"Originally we huddled in the dark.
Then we domesticated fire and used candles and oil lamps.
They were replaced by kerosene and gas lamps.
And Edison invented the incandescent bulb.

Now incandescent bulbs are being outlawed
to be replaced by Compact Florescent Lamps (CFL).
Soon CFLs will be outlawed due to the mercury in them
and they will be replaced by LED bulbs.
Then LEDs will be outlawed due to the arsenic in them
and we will be back to candles
Then candles and oil/kerosene/gas lamps will be outlawed due to carbon emissions.
and once again we will huddle in the dark. "


Always remember,
"You cannot help the poor by destroying the rich.
  You cannot strengthen the weak by weakening the strong.
  You cannot bring about prosperity by discouraging thrift.
  You cannot lift the wage earner up by pulling the wage payer down.
  You cannot further the brotherhood of man by inciting class hatred.
  You cannot build character and courage by taking away men's initiative and independence.
  You cannot help men permanently by doing for them what they could and should do for themselves."
  William J. H. Boetcker, Presbyterian Minister (1942 - often incorrectly attributed to Abraham Lincoln)
"There is nothing more difficult and dangerous,
  or more doubtful of success,
  than an attempt to introduce a new order of things."
  Niccolo Machiavelli, The Prince (1513)
"Tell people something they know already and they will thank you for it.
  Tell them something new and they will hate you for it."
  George Monbiot, Speech to the Enviromedia conference, Johannesburg, South Africa (5 October 2004).
On changing user interfaces,
William F. Buckley (he of the immense vocabulary) was once being interviewed by a young, brash reporter.
The reporter asked "Mr. Buckley, do you still use a typewriter to write your books?"
Mr. Buckley responded, "No, I use a word processor".
The surprised reporter asked, "which one?"
Mr Buckley answered "WordStar".
"WordStar", the reported said (almost shouting), "Why WordStar".
Mr. Buckley retorted, "I have heard that there are better word processors than WordStar, but I've also been told that there are better languages than English".

Scott's USTA Junior Tennis: Rankings 2002, 2003, 2004
USTA junior rankings were based on the Star (Sirius Software) point system until 12/03. Points were awarded (or lost) based on the difference betweeen an individual and his/her opponent's current point total over a 12 month period of play. The process was iterated until a stable rank order is established.
As of 01/04 the USTA switchied to an ATP/ITF-like system which is based on how far the player gets in each of his/her best 8 tournaments in the previous 12 months. There are also bonus points for extra-ordinary wins over highly ranked players.

 Marshal Wheeler 

Note: There are two different USTA national player listings
SSL - The Standings and Seedings List typically ranks more than 1000 players in each age/sex category. It is updated regularly (at least in the middle of each month) and is used to determine priority for entry into National tournaments.
National Ranking - The National Ranking List has more stringent participation qualifications than the SSL and normally lists fewer than 300 players in each age/sex category. Preliminary singles lists are published in the middle of each month and include results for the previous 12 full months; They are finalized at the beginning of the following month. The doubles lists are published covering a calendar year shortly after the end of each year. The ranking lists are archived (Starting in 1999) by the USTA.
Included Matches - Only matches played in National or high-level regional tournaments count towards National Ranking or SSL points.
Scott's ITF (International Tennis Foundation) Junior record
Scott's ITF (International Tennis Foundation) Men's record
The ITF uses a ranking system that is similar to that of the ATP. Points are awarded according to wins in an ITF tournament and the tournament's estimated level of play. In general, no points are awarded for a first round win or wins in a back draw. You need to have some points in the current year to have an ITF ranking
