I read a very interesting article in Foreign Policy magazine (online). It covers how US troops practiced and were equipped to use portable Nuclear devices.

As Capt. Tom Davis stands at the tailgate of the military cargo plane, the night air sweeps through the hold. His eyes search the black terrain 1,200 feet below. He grips the canvas of his reserve parachute and takes a deep breath. 

Davis and the men who make up his Special Forces A-team are among the most highly trained soldiers in the U.S. Army. It’s 1972, and Davis isn’t far removed from a tour in Vietnam, where he operated along the Cambodian border. His communications sergeant served in Command and Control North, which was responsible for some of the most daring operations in the heart of North Vietnamese territory. But none of the men has ever been on a mission like this before.

Their plan: drop into Eastern Europe, make their way undetected through forested mountains, and destroy a heavy-water plant used in the manufacture of nuclear weapons.

Leading up to the operation, during four days of preparation, Army regional experts briefed them on routes of infiltration and anticipated enemy patrols. The team pored over aerial photographs and an elaborate mock-up of the target — a large, slightly U-shaped building. It’s situated in a wide, open area with a roving guard, but at least the team won’t have to sneak inside.

Hanging awkwardly from the parachute harness of Davis’s intelligence sergeant is a 58-pound nuclear bomb.

Do not have much time. I thought the article was interesting enough to share. Its amazing how ingenious we can become if we want to do damage/harm/kill someone else.

Chess problem.

I play chess and have been working on being a better player. I only recently started playing quite a bit…. vs Shredder. I am really very very good at Backgammon. I am either World Class or Expert level most of the time.

Take a set of chess pieces and throw them all away except for one knight. Place the knight on any one of the 64 squares of a chess board.

Can you make 63 legal moves so that you visit every square on the chess board exactly once? As a reminder, a knight can move two squares in a straight line, followed by a ninety degree turn and a move of one further square. It might seem like a hard task, but this set of moves, called the knight’s tour, can be achieved in too many ways to count.

If you are able to make the 63 moves and end up on a square from which you can move back to the original square with the 64th legal move, then this is known as a closed tour. Other tours are called open tours.

This article is really about a math problem and the way to solve it.. Ants apparently use this technique all the time.



I have been very very interested in Cyberwarfare for several years. The discovery of Stuxnet was a signal of a new type of War in my estimation… It turns out it might be more difficult then previously imagined to wage Cyberwarfare.

Chess World Championships streaming…

I have been gone for too long. Various reasons for my being away. I am back and was shocked to see the blog is just as popular as it has been. I will continue now to update it with things that interest me and hopefully you as well. Thank you for continuing to visit the blog and taking time out of your busy lives to read what I may find important or interesting…

The world championship of chess is being contested between Carlsen and Anand. the following link should allow you to watch it and keep up on schedule and what the developments have been. I love Chess I am just not very good… I am much much better at Backgammon where I usually can play Expert or World Class level. I only really started playing Chess for about a year. I do have shredder so hope to improve.

Chess Worlds

Defending champion Viswanathan Anand on Tuesday gave his Norwegian challenger Magnus Carlsen a scare despite playing with black pieces even though the third game of the World Chess Championship clash ended in a long-grinding draw.

The third game turned out to be a hard fought affair lasting 51 moves after a rather sedate start that had seen the first two games ending in draws without any real excitement.

Midway into the third game today, Anand appeared to have seized the initiative with some ‘spot on’ manoeuvres, but the world number one Carlsen saved the situation with his counter play.

Chess links

I love playing chess.. there is just one major problem. I am not very good and do not really study it the way I do backgammon.

World Chess Federation (FIDE)


A huge database to chess matches played over the many many years games have been recorded.


Finally a link to a documentary that covers Magnus Carlsen the best player in the World and recently set the record for highest rating ever achieved topping I believe Bobby Fischer
