2017-10-15 (Summertime)

Today, I learned that:

On the Southern hemisphere, we are moving on towards the brightest season of the year. One of the signs of that is the adoption of daylight saving time, a.k.a. summer time, when the clock advances one hour instantaneously. However, the Brazilian government continues to make that happen at midnight, moving ahead to 01:00. Although this might not be a big obstacle right now, when moving back to standard time in February, 2018, it will occur once more at midnight, jumping back to 23:00. I think that the European model, where the change occurs at a time when much less people are active, involving 02:00 and 03:00, is much better, and its also does not involve two different dates. References #1 and 2 remembers that wonderful time of the year, seen through the hands and voice of George Gershwin and Janis Joplin.

And for the following people, in jail because of corruption, summer time may be some sort of relief:

Relief

Cartoon from Folha de S. Paulo today:
“-We managed to reduce your stay! -How much? -One hour. Summer time is about to start.”

In my post of 2017-09-29, I mentioned the word infinitesimal used in a broadcast from Radio National, Australia. In the same interview is also remembered the old commercial from Esso, “Put a tiger in your tank”, which can be answered by “What is the use of a tiger in tank, if there is a jackass at the steering wheel?” (See also the transcript in reference #3 below).

As a parallel, watch the two videos in references #4 and 5 below. So what is the use of high speed automated routing system for packages when they are treated so badly at the destination?

But everything in Brazil is not as pessimistic as it may seem from the examples above. The Swedish-Brazilian Chamber of Commerce (Swedcham) just published its annual survey of the business climate in Brazil for 70 Swedish companies. Despite the Brazilian recession, 36% of the companies say that they are satisfied with the present business climate. You can read the complete report in reference # 6 below.

Finally, here are two interesting examples of how AI (artificial intelligence) is helping out in the fields of health and beauty:

  • In an eye clinic in the Aravind hospital in Madurai, India, AI is examining photos taken of the eyes of diabetic patients. If they are not treated in time, there is a risk that they may go blind. So together with Google, the hospital has developed a computer program to examine the photos of the retinal fundus of the eye. Tests have shown that the program has the same accuracy as the professional ophthalmologist, up to 90 %, and in much less time. See references # 7 and 8 below.
  • Intel has developed a mobile application (named Face It) that uses computer vision to acquire data about a user’s facial structure as well as machine learning to determine the user’s face shape. This information is then combined with manually inputted information to give the user a personalized set of hair and beard styles that are guaranteed to make the user look his best. A personalized list of tips are also generated for the user to take into account when getting a haircut. See the screenshot and reference # 9 below.

Today, I learned that:

Even if you loose your voice, there are now ever better means of communicating with other people. Of course you can write, if you are able, but you must agree with me that an audio is much easier to grasp than a text, one can continue with most other activities and still understand what is being said. (But take very much care, even if you use a handsfree mobile phone in your car, your attention to the ongoing call is often so high that you can be a menace to other drivers, cyclists, and pedestrians.)

Yesterday, I watched the 2014 movie about Stephen Hawking and his first wife Jane, “The Theory of Everything”. In the very moment when Stephen is first heard through his mechanical voice, Jane is pretty excited, but complains that the voice has an American accent. If that had happened today, the genius, who recently celebrated his 75th anniversary, could use his own voice, although generated artificially. More about the movie and Stephen Hawking can be found in references #1 and 2 below.

And now over to the story about Jason Liversidge and his new voice: Just like Stephen Hawking, Jason, who lives in Yorkshire in northeast England, suffers from the neurological disease called ALS. The first symptoms appeared almost 10 years ago, but it was only three years ago that he got the diagnosis of ALS. His own voice is still working, but sometimes he needs a backup voice, and then he can use his computer which generates sounds with the same accent as Jason’s, “not the posh English accent”. His artificial voice was created from a video recording of a speech he made some years ago, combined with speech from other men from Yorkshire. A research institute in Edinburgh, Scotland, were then able to recreate Jason’s voice synthetically. The proper Jason and his family recognize the similarity of both voices. Reference #3 appoints to the radio program from Radio Sweden (in Swedish) which tells the whole story.

Exactly one year ago, 2016-03-12, I published a video showing Atlas, a robot from Boston Dynamics performing gracious movements. But it did not stop there, look at this video of its newest sibling, Handle, in reference # 4 below, SIMPLY AMAZING!

Ponte da Amizade (“Bridge of Friendship”) joining Foz do Iguaçu – PR, Brazil, where the photo was taken on 2017-01-26 by my daughter, with Ciudad del Este, Paraguay, in the left side.

The photo above shows another view of the Paraná River, this time from the Brazilian side, shot 200 km South of the photo from 2016-11-30. It shows the bridge interconnecting the Brazilian city of Foz do Iguaçu – PR, to the right, and the Paraguayan city of Ciudad del Este. Not long ago, this bridge used to be packed with people and cars returning to Brazil from a shopping spree in Paraguay, but the ongoing financial crisis has also here had a devasting effect. (I already published a photo from Foz do Iguaçu on 2016-01-28).

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.

Go45

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

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” !!!
