Today, I learned that:

On Sunday evenings or afterwards as a podcast, one of my favorite technology programs is Leo Laporte’s This Week in Tech. Among other things, this week’s edition discussed at length a draft of a US Congress bill to obligate any provider of encryption solutions to data communication to also offer means of decrypting it when summoned by the authorities. Scary stuff! Reference #1 below appoints to the TWiT show.

Reference #2 below discusses the same draft, and here is a citation of that article:

“Feinstein-Burr ‘encryption bill’

A draft of the long-awaited Feinstein-Burr ‘encryption bill’ surfaced late Thursday night and has law and tech experts reeling.

“To uphold both the rule of law and protect the interests and security of the United States, all persons receiving an authorized judicial order for information or data must provide, in a timely manner, responsive, intelligible information or data, or appropriate technical assistance to obtain such information or data,” the discussion draft states.

The draft of the “Compliance with Court Orders Act of 2016” essentially requires any device manufacturer, software manufacturer, electronic communication service, remote computing service providers, “or any person who provides a product or method to facilitate a communication or the processing or storage of data” to comply with court orders and hand over any plain-text communications the government demands.

Tom Mentzer, press secretary for Senator Diane Feinstein, D-CA, who is heading the bill alongside Senator Richard Burr, R-N.C., shared their joint statement to Digital Trends: “We’re still working on finalizing a discussion draft and as a result can’t comment on language in specific versions of the bill,” according to the statement. “However, the underlying goal is simple: when there’s a court order to render technical assistance to law enforcement or provide decrypted information, that court order is carried out. No individual or company is above the law. We’re still in the process of soliciting input from stakeholders and hope to have final language ready soon.” But Mentzer also said “nothing has been released by the committee,” meaning the discussion draft will likely be revised greatly before it becomes a bill.”

Today, I learned that:

This morning, I read an interesting article in Folha de S. Paulo. After all the problems we have had with the viruses transmitted by the mosquito Aedes Aegypti (Zika, dengue, Chikunbunya, yellow fever), now there is an epidemic spread of the swine flu, H1N1. Therefore, let us hope that the contents of this article may result in a big relief in a not too distant future.

The interesting subject is about developing a universal anti-flu vaccine. There are at least 31 candidates being tested, most of them still in the pre-clinical phase, i.e. before being tested in human beings. Read more in reference #1 below, a article in Portuguese. A article about the study done so far was recently published in the “Vaccine” magazine, at the end of March, 2016.

The header photo shows the TV-tower Pearl of the Orient in Shanghai, on a photo I took on 2005-04-10. Below are more photos from the same interesting Sunday sightseeing in Shanghai. Tomorrow, there will be more.

Today, I learned that:

Every Sunday morning, Radio Sweden’s domestic channel P1 transmits a 2-hour news program named “Godmorgon, världen!”, which means ‘Good morning, world!’. It is supposed to be a radio alternative to the Sunday newspaper, and as such discusses hot issues from the preceding week, mixed with satire and chronicles. The big political discussion was an analysis which impact the Panama papers may have on the world in the short term. But what I remember most from today’s program was a chronicle by the Swedish journalist and author Göran Rosenberg, who declared his worries about what is happening to the majestic ash tree, formal name fraxinus excelsior, that he sees is slowly being deprived of its beauty, due to plagues.

Here is a translation into English of an excerpt from the chronicle: “The ash tree is not only a big tree in the cultural landscape, it is also a big tree in the cultural history. Yggdrasil, the world tree, which according to Nordic mythology carried the cosmos in its branches and from which Oden [the main god] created the first human being, was an ash tree. Only that fact alone tells us how long the ash tree has been together with us.”

The complete text, in Swedish, can be found in reference #1 below. The Wikipedia article in reference #2 below give more facts about fraxinus excelsior.


Fraxinus excelsior in winter in the Swedish village Gammelbo. Male in front, female behind. Please observe that the female tree is smaller than its male companion, in spite of having been planted at the same time.

Exactly 11 years ago, I had the pleasure of circling the globe. My company, which previously had dealt with electronic production machines from the Western hemisphere, had decided to find new partners in Asia. So, therefore, I left São Paulo for a quick visit to my father in Sweden, before I boarded the SAS Airbus 343 in Copenhagen on 2005-04-08. The trip from Copenhagen to Pudong airport in Shanghai, China took some 10 hours, the business class cabin was wide and comfortable. In the chair to the the right was a German man, who was going for business in the chemical industry in Shanghai. But what I remember most from this leg was the in-flight WiFi provided aboard. 1,5 months before, I had joined Skype, and now I could call friends and family while looking down on the Siberian tundra, an interesting sensation.

When we arrived at immigration, for which I had a obtained a fresh visa in my passport and received a shot against yellow fever, they did not even look at those documents. No guide of mine was to be found, so the German man’s business contact dropped me off at my hotel hotel downtown Shanghai. After a relaxing nap, I went out in the afternoon and walked around the streets to feel the city. Since Saturday night was approaching, the streets got filled with people enjoying their weekend. See below some photos I took on Saturday, tomorrow I will show some more from the following day.

Today, I learned that:

Today marks exactly three months since I wrote my first blog post. It has been a very interesting period, I have tried to vary the subjects and also the languages used. And I must sincerely thank all my faithful readers for comments and suggestions.

Although my interests lie mainly in technology, I have found that the subject that attracts everyone is food. So today, I will give you two new pieces of information relative to food, which I believe that most people did not know.

It all started yesterday night, when I received the latest edition of the podcast KCRW Good food from Los Angeles, always so fascinating with the always so enthusiastic Evan Kleiman. One of the topics in this program was about childrens’ food habits. “The Flavor Window” is the period between four and sevens month of ages, when human beings are more receptive to new flavors than they will ever be, so if there is something in particular you believe your child should learn to like, that is the time! (In a similar way, if you want a person to learn a foreign language and pronounce it well, it must start before the child is in the five to six-year age, because until then the vocal chords are still flexible enough to learn how to pronounce almost any sound.) “Good food” can be heard through the link in reference #1 below.

A popular sauce in adults food is the Italian pesto sauce. Today’s edition of From our own correspondents, BBC’s traditional program with chronics from abroad, among our things, talks about how to make an original pesto sauce, and who knows, maybe participate in the World Championships in pesto sauce making, held right now in Genova. More details in reference #2 below.

Today, I learned that:

Music has fascinated people in all times. I remember that when I was in elementary school, we practiced to sing the traditional songs for the major holidays as a choir. And although I have never had any good voice to sing, I thought that the experience of singing in a choir was quite thrilling.

Yesterday, I heard yet another podcast from Scientific American, which informed that a cancer center in the U.K. found that patients had significantly lower levels of the stress hormone cortisol after harmonizing for an hour. For more information, consult reference #1 below.

And then I also remembered news about how people singing in a choir entered into a state of synchronization even of their heartbeats. See more about that study from 2013 in references #2 and 3 below.

From there to the fantastic Swedish film “Så som i himmelen”, in English ‘As it is in heaven’, which competed for an Oscar in 2004, the connection was obvious. If you have seen it, you do not know what you are missing! See also reference #4 below.

And yet another film on the same theme is from 2012, ‘Song for Marion’, in which a cranky old man finally joins his dying wife in the joys of singing (reference #5 below).

Today, I learned that:

The news we received earlier this week that the digital communications application WhatsApp has finally received end-to-end encryption of all messages sent is definitely a welcomed one. That way, one can start to use it also in areas where we would not dare using it before. But do not think that now you can relax your own security measures. Reference #1 gives a good explanation about the whole situation now.

But did you ever wonder how a company can produce an application used by one billion users and suffer from low indices of downtime? Which is the underlying structure, e.g. which programming language was used to permit the creation of a such a largely scalable system and permit it to be used in real time? The answer is that the creators of WhatsApp got inspired by Erlang, a programming language originally created in the 1990’s by the Ericsson engineer Joe Armstrong to be used as a base for the data switching version of their flagship central office AXE system, named AXD 301. In 1998, Erlang was released as an Open Project. Reference #2 below can fill in all the blanks in that story.

Idag lärde jag mig, att:

Har man tillräckligt med pengar så gör man vad man vill. Det har blivit uppenbart när Panamadokumenten nu avslöjas. I morse redogjorde SRs utrikeskorrespondent Staffan Sonning för hur det fungerar att trolla bort skatt på de surt förvärvade pengarna, lyssna på krönikan i referens nummer 1 nedan.

Men allt är inte bara elände i världen. Häromdagen fick jag ännu ett nummer av Chalmers magasin i min brevlåda. Förutom de som alltid interessanta artiklarna om vad forskarna har kommit på nu, så var det två notiser på sidorna 4 och 5 som drog till sig mitt intresse:

För fjärde året i rad toppar Chalmers TNS Sifos anseendemätning över svenska universitet, med betyget 89 på den 100-gradiga skalan, vilket uttyds som “utomordentligt anseende”.

Ansökningar från internationella studenter att börja höstterminen 2016 på Chalmers är rekordstort, 10 822 ansökningar, en ökning med 63 % i förhållande till fjolåret. Det totala antalet ansökningar från utlandet till alla högre utbildningar i Sverige ökade samtidigt med 46 %, så även här stärker Chalmers sin position i Sverige.

Läs hela utgåvan i referens nummer 2 nedan.

… Tack för idag, slut för idag!

(This post in Swedish deals with how easy it is to vanish with your money, and also about how my alma mater, Chalmers, is strengthening its position, both in Sweden and abroad.)

Today, I learned that:

In a world with so much violence, crimes and frauds, one could expect that at least sport competitions would give us some time to recover our senses and enjoy them.

But unfortunately, there is so much mischief going on also in sports, that it further adds on to all the other stress items we have to endure.

This morning, I read in Folha de S. Paulo, see reference #1 below, that the government of the State of São Paulo, for safety reasons, will not permit that the supporters of the away team in the matches among the teams from the capital, the so-called “classical matches”, be present in the stadium. The drop that made the bottle flow over was the violence last Sunday, in connection with the match between Palmeiras and Corinthians. A person waiting for his bus home at a bus stop was shot and died. He had nothing to do with the fighting supporters, just happened to be “at the wrong place at the wrong time”.

In Sweden, the premium football league, named “Allsvenskan” started the 2016 season last Sunday. The public attendence was good, even higher than the icehockey games of Swedish Hockey League, but there is one thing that I find most distressing in relation to the so-called “supporters” who find more pleasure in lighting artifical fires, “Bengal fires” on the grandstands, instead of concentrating themselves on the game. How about arranging separate competitions between Bengal supporters instead, who can create the finest, multi-coloured, smoky fires, so that real football fans can watch their game without the incendiary disturbance? If you are literate in Swedish, listen also to the interview in reference # 2, where the police give their negative opinion about this practice.

Today, I learned that:

If you like salt in your food but know that you have to take very much care in order to not overdose the salt contents, since too much sodium will raise your blood pressure, could there be a different way of feeling the same food sensation without putting your life in danger?

Researchers at the University of Tokyo’s Rekimoto Lab have come up with an interesting alternative, sort of best of both worlds. They have built a prototype of an electric fork, which uses electrical stimulation to simulate the taste of salty or sour ingredients.

The battery-powered fork features a conductive handle that completes a circuit when the tines make contact with a diner’s tongue, electrically stimulating their taste buds. It has has adjustable levels of stimulation, to adapt to individual tastes. However, before thinking about making it available to the public, they have to overcome a problem, because if pushed too far, the fork can produce an unpleasant metallic taste in the mouth.


Bon (and healthy) appétit !

Idag lärde jag mig, att:

Vår värld är verkligen varierad, även om det finns likheter mellan Norr och Syd. Till exempel är det som så att fler och fler politiker av olika färg och nationaliteter börjar ertappas med att först ta vara på sig själva och skicka “sina” pengar till något skatteparadis.

Så har det varit länge i Brasilien, även om det som nu håller på att avslöjas överstiger allt som vi har hört talas om tidigare. I dagens God morgon världen i SR P1 rapporterade SRs korrespondent i Latinamerika, Lotten Collin, om en brasiliansk satirsajt som verkligen har lyckats fånga situationen på ett kusligt sätt. Lyssna på reportaget i referens nummer 1 nedan.

Och i samma program fanns det också ett intressant inslag om hur man använder hundar i Kambodja för att tillaga deliciösa maträtter. Reporter där var Alex Kronholm. Hör inslaget i referens nummer 2 nedan.

Så slutligen i Ekot kvart i sex fanns det också ett inslag från Island, där man har upptäckt att statsministerns fru föredrar att placera pengar på Brittiska Jungfruöarna. Reporter ännu en gång, den välbereste Alex Kronholm! Hör inslaget i referens nummer 3 nedan.
