Today, I learned that:

We have arrived at the Easter weekend and in most countries where Easter is celebrated, it is normally Easter Sunday which attracts the main interest culinarywise. Sweden is an exception, there it is Easter Eve, Saturday, that has that attribute.

So I would like to contribute with a marvellous dessert to break the normal sweets tradition. Avocado for most people is known for its use in appetizers, e.g. filling it with prawns, caviar, etc., and of course as a guacamole dip for the tortillas or nachos. But in Brazil, we like to eat the avocado sweet, mixing its pulp with sugar and water / milk, to form a delicious cream. See the photo and reference #1 below.

Creme de abacate

Avocado cream is extremely simple to make, and yet it is so tasty. Just divide the fruit in two halves, scrape out the pulp and place it in a blender. Add some sugar and a liquid, either water or milk. Dose and blend well to desired consistency. If you use water, then some lime will give the cream a delightful contrast. But do not add lime if you are using milk, they do not go well together chemically.

This morning, I heard some distressing news from the local news program of SR Sjuhärad. It was reported that the new EU regulations about traffic safety does not oblige the car driver to have his/her tail lights lit when out driving in the fog. To me, and so many others, that seems like a dangerous degradation of the safety rules. Let us hope that the human drivers have more wit than the EU legislators and leave the lights on. See also reference #2 below.

In two earliers posts, 2016-03-10 and 2016-03-12, I reported about the outcome of the first three games of Go in a best of five series challenge between the AlphaGo computer and the Korean master Lee Sedol. Here comes the final report, in which Lee won his first game and AlphaGo won one more. So the challenge victory went to AlphaGo with a 4-1 match record.


The results of games 4 and 5 in the challenge series between AlphaGo and Lee Sedol show how the two opponents won one game each. The final result of the 5-game series is thus 4-1 to AlphaGo

… That’s what I learned in school !

Today, once more I learned that:

There are machines all around us, performing all kinds of tasks. Below are three interesting examples of their versatility.

Solution to Problem # 4, Drilling square holes, posted on 2016-03-06

The question was: How would you construct a tool to drill square holes? The solution can be found in the following drawing. See also the amazing video in reference # 1 below.

Corner mill

This drawing from the Japanese company Dijet show the principle of successive milling of the corners of the hole, which results in a square hole.

Update on AlphaGo vs. Lee Sedol

Just as we could expect, AlphaGo did it again, and won also the third game against Lee Sedol. There are still two more games to go, but the 3-0 lead that AlphaGo already has is of course sufficient to win the match. See the following images and reference #2 below.

A robot I would not mind having as my partner

Here comes a perfect example of how advanced robots are today. It is the US company Boston Dynamics that has developed Atlas. How about teaming up AlphaGo and Atlas, thus forming the ultimate Go player? See the following photo and another fantastic video in reference #3 below.


Atlas lighting a box weighing 4,5 kg. I suggest that Google employs him together with AlphaGo to form an invincible Go player.

2016-03-10 (Thursday)

Today, I learned that:

The world is undergoing a constant evolution, and in the field of technology it seems more evident than ever.

Do you remember Deep Blue, the first computer to beat a human world champion in chess? It happened in 1996, when it won the first game of six against Garry Kasparov, although Kasparov came back and won the series with 4-2. But in 1997, Deep Blue got its revenge, winning a tough series of games with 3,5-2,5. Deep Blue was a joint project between IBM and Carnegie Mellon University. Kasparov accused IBM of cheating and demanded a rematch, but IBM denied it. Later it was the inverse, IBM challenged Kasparov again, in vain. However, Deep Blue gave inspiration to other chess playing programs and nowadays it is quite common to see human chess players go up against their virtual opponents. See also reference #1 below.

Then came Watson, yet another implementation from IBM. In 2011, a computer won the popular quiz game of Jeopardy! against the champions Ken Jennings and Brad Rutter. IBM later continued development of Watson further into a commercial application for management decisions in lung cancer treatment, announced in 2013, see reference #2 below, and an update in January 2016 (reference # 3 below) gives more recent examples of where Watson is finding applications for its skills.

Both Deep Blue and Watson are good examples of what is commonly called Artificial Intelligence (AI), and yesterday, 2016-03-09, represented another historic date for AI. This time, the application is playing the ancient Chinese boardgame Go, considered to be far more complex than chess. The British company Deep Mind started in 2010 to develop a computer system which purpose was to play Go the way no man (or machine) had ever done before. Google acquired the company in 2014 and here comes the graduation task for AlphaGo: beat the world’s leading Go player.

The series of best of 5 games, which is held in Seoul, started yesterday, when AlphaGo won the first game of Go against the world’s best player, the Korean Lee Sedol. Also in the second game, held today, AlphaGo defeated its opponent, and unless Sedol wins the remaining three games, we will have proof, once more, that well designed computers can beat the best players in the world in their respective specialities. The following images show the result of the first two games. For more information about the match and Go in general, see references #4 and #5 below.

Finally, although the machines are clever, do not forget that there are humans behind them, responsible for the programming. Reference #6 below talks about a case revealed today about how hackers were able to transfer US$ 81 million from the US Federal Reserve Bank in New York to Asia, completing thus 4 of the assigned 13 transfers. But on the fifth task, a routing bank in Germany detected a misspelling of “foundation” as “fandation”, which stopped the remaining US$ 850 million from getting stolen.

This reminds me of the old slogan for Esso gasoline to “put a tiger in the tank”. Such a procedure will not have any effect if there is “a jackass sitting behind the wheel” !!!
