This blog feature amusing and heartwarming stories about our late Leonberger dog Bronco, as well as other Leonbergers. It also has a lot of information about the Leonberger breed, the history, care, training, Leonberger organizations, etc. I also wrote a Leonberger book, which I am featuring in the sidebar.
Other topics not necessarily related to Bronco, Leonbergers or dogs.

I wanted to write a post about craft beer, but I realized that putting everything I wanted to say about craft beer into one post would make it a very long post. I am starting with a post about fruity beers, craft beers or otherwise.

First a word about Lager beer. Lager beer is a relatively recent invention that originated in Bavaria. Lager beers use a special kind of yeast for the fermentation process, it is typically bottom fermented, and fermented and conditioned in cool temperatures, unlike other beer styles. Lager beers can be of many colors, pale, amber, dark, even black such as Schwarzbier. The Pale Lager originated in Pilsen in Bohemia (Western Czech Republic) in the mid-19th century. The pale lager has become the world’s most common beer style and bland tasting mass-produced pale lager beers dominate the market. In countries that are not traditional beer countries such as France, Italy, China, Japan and South America, the bland pale lager is very dominant. I’ve come across many people who think that the more tasteless the pale lager is, the better beer it is (Corona).

Many people believe that beer is the same thing as pale lagers. However, the beer advocate counted 120 beer styles (so far). I can add that some mass-produced American pale lagers, such as Budweiser, contain adjuncts, such as rice and maize, which is prohibited by the German Reinheitsgebot tradition. The Reinheitsgebot tradition states that the only ingredients allowed in beer are water, malt, hops, and yeast and for bottom fermented beer (lager) the malt must be malted barley only. Therefore, what many people think of as beer, well, it’s complicated.

Beers with fruity flavors
Pale lager beers aren’t associated with fruity flavors, which can lead to the incorrect impression that beer with fruity flavors isn’t real beer. However, beers with fruity flavors have a very long history, and many fruity beers, perhaps surprisingly to some, follow the German Reinheitsgebot tradition. In addition, many beers with fruity flavors are among the most celebrated beers in the world. There are many fruit Lambics (Belgium) that are sold for several hundred dollars per bottle. There are a number of ways to add fruit flavors to beer.
Below are some photos of beers with fruit flavors







I’ve got a number of hobbies, one of them being learning French. Back in December I took and passed the DELF / CEFR B1 level language test in French. The CEFR is a European standard for assessing an individual’s language proficiency that is being adopted around the world. It includes all European languages as well as other languages. The A1 & A2 tests are for beginners with A2 being more challenging. The B1 and B2 tests are for independent speakers, meaning you can get around without help, listening to the news, having conversations, etc. C1 & C2 are advanced levels, like native speakers and experts. If you immigrate to France, you need to pass the B1 test to become a citizen. Most countries do not have such a language requirement for citizenship. The A1, A2, B1, B2 tests (and maybe C1 & C2) consist of four parts but the different tests have different difficulty levels.

To pass the test you need 50 out of 100. As mentioned, the test is designed to assess your level. It is not like a test you take to get a grade at school. Therefore, if you do what is expected of you at the B1 level you may get 50-60 points and more if you can do more. If you get 80+ on the B1 test, then you probably should have taken the B2 test. There are no A, B, C, D or 1,2,3,4,5 grades.

There are a couple of things that come to mind regarding these tests.
Learn to Speak 25 languages in one hour!
Yesterday I saw an advertisement on Facebook for the Pimsleur approach that stated, “start speaking a new language after just one lesson”. Well, I used the Pimsleur approach for French for a short while and I remember the first half an hour lesson. You learned to repeat one short sentence. That’s not speaking a new language in my opinion. The advertisement sounded like there should be more to it. I should say I think the Pimsleur approach is a good approach. It is the ad I have a problem with. I’ve seen other language program commercials stating that you will become fluent in 24 hours, or become conversant right away, and many other ads that are just BS.
There are some language geniuses but most of us need a lot of practice to learn a second language regardless of method. There is no way around the fact that you need to know a few thousand words, internalize sentence structure and grammar, etc., before you can be fluent. I think one reason these language companies get away with unrealistic promises is that many people expect ads to be BS and another that many language learners greatly overestimate their proficiency. These universally accepted tests are great for assessing true proficiency.

When our younger son (pictured above) was 6-7 years old my wife used to play a song in the car that featured Hello and Goodbye in 25 languages, and he learned that song. One day I was having a conversation with a waiter at a restaurant who noticed that I had an accent. He was curious about my native language Swedish. That’s when my son told him “I speak 25 languages”. So, the waiter started asking him questions about how to say hello and goodbye in the various languages he claimed to speak, and he knew. So, the waiter asked me, “does he really speak 25 languages?”. I said, well that’s what he says. Perhaps, the language companies could put this song in the first lesson and then claim, not entirely incorrectly, that with their method you’ll speak 25 languages in one hour.
Proficiency assessment for other subjects
I sometimes wonder if rather than assigning grades to students it would be more practical to allow people to attain certain levels in one or more fields that they are interested in. Naturally, people could reach their levels any way they like, and not necessarily through the university system. Considering the many failures of modern universities, extremely high tuition, student loan issues, grade inflation, crazy partying and drugs, failures to protect girls from sexual assault, political indoctrination, antisemitism on campuses, fewer people going to college, parents losing faith in universities (including myself), and the list goes on, maybe it is time for something new. What should replace it I don’t know. Perhaps assessing proficiency levels instead of class grades could be part of it.
Someone suggested that I write a little bit about my background in Robotics and the fact that I did a PhD in Robotics (Department of Electrical Engineering and Applied Physics). My thesis involved the emulation of basic animal behavior such as reflexes and fixed action patterns, as well as tree-search based artificial intelligence. I used neural networks in other contexts, but not for my PhD research. It also involved quite a bit of non-linear robot system control and the study of chaotic systems. I implemented my research on many kinds of robots but the robot I used the most was the 7-degrees of freedom Robotics Research Corporation Robot pictured below.

It looks messy in the picture, and I should probably explain. I had hung a few boxes from the ceiling and placed a coatrack in front of the robot. There is also another robot just outside the picture to the left. I placed a sonar sensor, or perhaps more correctly eco-location equipment on the tip of the robot. I used the sonar/eco-location to create a 3D map of the robot’s surroundings. Since the sonar-sensor could not see everything at once I used the arm of the robot to search and investigate the surroundings, including discovering that the boxes were open on one side. The motion of the robot was guided by the sonar and was not directly programmed by me. The robot was able to avoid colliding with the objects, including the other robot as it was moving. I moved objects around and added clothes and hats to the coatrack to make it harder. It looked like an animal figuring out what was around it. This was in 1993.

Maybe I should explain what 7-degrees of freedom mean. One degree of freedom could be a rotation (around a joint) or a translation. To arbitrarily position an object in space you need at least three degrees of freedom. To arbitrarily orient an object in space you need an additional three degrees of freedom. So, to arbitrarily position and orient a tool in space you need at least six degrees of freedom. Industrial robots frequently have six degrees of freedom. However, if you also want the robot arm to avoid collisions with objects in its space you need an additional degree of freedom. That’s why I needed a 7-degrees of freedom robot.
In the picture below an arc welding robot PW-10 is moving around unaware of its surroundings. The RRC robot detects that the PW-10 is in its space and perhaps approaching and quickly gets out of the way. Reflex control in action.

Robotics can be Math heavy (Algebra, Trigonometry, Calculus)
Part of the job of creating the control system is to create the kinematics, dynamics, and perhaps inverse kinematics, for the robot, and this is math heavy. Lots of algebra, calculus and trigonometry. I have included the Jacobian matrixes for the first four degrees of freedom for the RRC robot below. Just to illustrate how math heavy it is, and this is just four degrees of freedom. Note, doing this was not part of my research. It was just a basic mandatory task to get the robot to move predictably before you even get started.
I should say that as soon as I finished my PhD, I was offered a job at JPL in Los Angeles to work on an 11-degree of freedom robot that was supposed to be on the International Space Station. However, the government cut the funding for the project, so I never got to do it. Instead, I took a job with ABB Robotics. I did not get to do the math for the 11-degree robot but one of my first tasks at ABB Robotics in Wisconsin was to create the kinematic matrixes for more than 20 ABB robots.
Algebra is indeed a good skill in many professions. A lot of engineers, scientists, mathematicians, IT professionals use algebra in their work, and algebra teaches you how to think logically and methodically. Therefore, schools should teach it. Which is why I don’t find this common joke funny “Another Day Has Passed And I Didn’t Use Algebra Once”. I don’t find “Another Day Has Passed And I Didn’t Play An Musical Instrument Once” funny either but somehow I think the problem with the joke is more obvious to some people in the latter case.

Today, December 13, is Saint Lucy’s Day (Santa Lucia in Swedish) in Sweden. On this day girls or young women dress up in white robes and the chosen St. Lucy places a crown of candles or lights in her hair, The other girls/women are referred to as “Tärnor”. Boys dress up in white robes and wear white cones on their heads. Some of the boys dress up as gnomes. Then they march through the streets or inside buildings. They sing songs and hand out Lucia buns, gingerbread cookies and other goodies. They typically do this early in the morning while it is still dark. If the Lucia group is inside, you typically turn off the lights to create the right ambiance.

This evening my daughter surprised me by baking the traditional saffron buns, so called Lusse Bullar or Lucia Buns in English. She prepared a Swedish meatball dinner and dressed up as St. Lucia. I had completely forgotten about St. Lucy, so it was a surprise. She did not want her picture online, so I am including online photos of St. Lucia.





St. Lucy takes place during the Nobel Week. The Nobel award ceremony happen on December 10. It should be noted that we often speak of the Nobel Prize, but there are six Nobel Prizes. The prizes for Physics, Chemistry, Physiology or Medicine, Literature, and Economics, are awarded in Stockholm, Sweden. The Nobel Peace prize is awarded in Oslo, Norway.
Anyway, On December 13 a St. Lucy parade visit and sometimes surprise the Nobel Prize winners in Stockholm who are staying for a few days (they stay at the Grand Hotel). In the past, these surprises did not always work out well, as the St. Lucy group of white dressed women sometimes frightened laurates from East Asia. In East Asia white dressed women are often thought of as ghosts (yūrei and onryō). Think of Samara Morgan in the Ring movies. Therefore, they modified how the Lucia train (as it is called) marches through the hotel. For example, they no longer show up in people’s rooms unannounced.
As a little piece of interesting information this is a list of this year’s Nobel Prize winners.
Someone reminded me that today is the day of writing, so I decided to make a blog post even though I made one yesterday. This post is not about Leonbergers or dogs but about our visit to the ice hotel in Jukkasjärvi in northern Sweden. It was 2005 and the kids were still small. It was the first ice hotel in the world and is the biggest one.
I should say that Jukkasjärvi is located north of the arctic circle and is typically very cold in winter. The ice hotel itself does not have any bathroom, but they have an adjacent wood building with bathrooms, showers, and rooms for anyone who can’t stand the cold for too long. If you are OK with being a bit cold, you sleep in sleeping bags on top of blocks covered by reindeer hides. Below are some selected photos that I took.

The ice hotel had put out lots of kick sleds, referred to as “spark” for people to use as a mode of transportation on the snow and ice, or just to sit on. As my dad, Stig, was sitting on one of them, our son came up to him and told him “Stig the hotel put out these sleds for children to play with. It is not for adults to sit on.” My dad was so surprised that he just handed him the sled.










The day after I took some photos of the other rooms.







Would you stay at an ice hotel?

I opened my eyes and stared at the ceiling. As I tried to get out of bed, I realized I couldn’t move. No matter how hard I tried I couldn’t move a finger. I heard my parents talking downstairs so to get their attention I tried to scream but I couldn’t. I was completely paralyzed, and I did not understand how it had happened.

Then I saw three beings coming out of the walls, like the Cenobites in Clive Barkers Hellbound Heart. I should say I had not read the Hellbound Heart book or seen the movie at the time. It was just how it looked like. As they came closer, they looked down at me, and I realized that they were the Beagle Boys from Duck Tales. They promptly started to torture me by sticking long needles into my back, and it really hurt. I knew it was some sort of hallucination, but I didn’t know how to stop it.
When you dream you don’t know that you are dreaming, and logic and common sense does not work. This was different. I was fully aware, and I understood that what I felt and what I saw couldn’t be real. I guessed that I had some sort of condition causing a hallucination. I would later find out that it was sleep paralysis, a sort of mixed state between being awake and asleep. It happened to me several times during my teenage years and later on it happened to me once as an adult.
Have you ever had sleep paralysis?
In my recent post called “Culture Shock Sweden USA” I included a photo of myself opening and smelling a can of north Swedish fermented herring, or as it is properly called “surströmming”. It is a specialty from the north Swedish Highcoast where I grew up. Underneath the photo I wrote “Unfortunately, all the Americans experienced a culture shock from the fermented herring.” See the excerpt below. What I should maybe have mentioned in my post is that even though it was a joke, it was still true. People were not ready for what was coming.

After I had posted “Culture Shock Sweden USA”, I posted a link to my blog on my Facebook and I received a few comments including comments from two people who actually were there at the fermented herring party in 1987. I’ve included the comments below.
Surströmming first-timer videos are getting pretty common these days, but I still always end up laughing until I can barely breathe when they start the uncontrollable retching! Always reminds of the Surströmming party and that nasty prank we pulled on the residents of Glaser House! 🤣 — Lee
Delicious memories….NOT!!! 🤢🤮 — Alyce
What happened was that as soon as I opened the can, all Americans dashed for the windows or doors trying to escape the smell. In the party invitation we had left out one or two details, like that surströmming is often said to be the worst smelling food in the world. The “nasty prank” Lee was referring to was me and him going around the dorm and placing left over surströmming in the ventilation drums of the dorm. I admit that was immature. Luckily, it did not work as well as we had hoped, or we probably would have both been expelled.

This is an excerpt from Wikipedia on the topic:
Since gaining notoriety as one of the world’s smelliest foods, surströmming has become the focus of a number of “challenge” videos on YouTube and other platforms where people uninitiated to the food show themselves opening a can for the first time, usually to visceral reaction, and then try to eat the fish without additional preparation. Often the videos show the participants gagging, swearing, holding their nose, or vomiting.
To read more about surströmming on the disgusting food museum’s webpage click here.
In the end we had a good time. The smell dissipated and people ate and drank other things we offered. We swedes ate the surströmming but a few others tasted a little bit as well. We knew what the reaction would be, and we did not offer the fermented herring in the hopes that people would love it. It became a good source of conversation and jokes, and that’s what we hoped for. I should say that you normally open the cans outside and let the smell dissipate before you eat them. The surströmming taste mostly like pickled herring with lemon and lots of salt and you typically eat with onion and potato or rolled in soft and thin bread (tunnbröd).

Have you eaten any weird foods?
This post is not about Leonbergers but about something entirely different; culture shock, which I think is an interesting topic. The Merriam-Webster dictionary defines culture shock as : “a sense of confusion and uncertainty sometimes with feelings of anxiety that may affect people exposed to an alien culture or environment without adequate preparation”.

In 1987 I was selected to be part of a university level exchange student program. The exchange program was between Uppsala University in Sweden and Case Western Reserve University in Cleveland, Ohio. In total we were six Swedes (two from Uppsala). I was studying Engineering Physics in Sweden but in the US, I would continue studying Electrical Engineering because the Swedish Engineering Physics program was very similar to the Electrical Engineering program at CWRU.




I arrived in the US in August 1987, and I was not well prepared for what I would experience. That doesn’t mean it wasn’t a great experience but there were challenges. Interestingly, I would later experience reverse culture shock. Reverse culture shock means that after adjusting to your new country you experience another shock when coming back to your old country.

One of my first unpleasant discoveries was that the US uses imperial units instead of the metric system unlike most of the rest of the world. I quickly had to learn how to use inches, feet, miles, ounces, pounds, cups, gallons, etc. I knew about miles per hour versus kilometers per hour, but it had not dawned on me that it applied to everything. This is quite important in engineering.

The academic environment was also quite different. In the US there were fewer classes, but you were often required to participate and there were quizzes and homework in addition to the final exam, which was short and relatively rushed. In Sweden you showed what you had learned on one big final exam that lasted 6-8 hours. How you achieved success on that exam was up to you. Well certain lab work had some weight also.

In addition, in Sweden there were no dorms, no fraternities, no Greek life, no meal plans, no college sports teams, no tuition, and no health insurance. Attending a university in Sweden is more like working for a company. You are more independent, and tuition is free, and Sweden has national healthcare. In Sweden there are clubs, organizations, and parties you can go to, but it is more adult and has no likeness to fraternities. I have no opinion on which system is better, but it was a challenge to suddenly adjust to a dorm, meal plans, a different kind of student life, tuition waivers (provided by Uppsala University), etc.

Another difficulty was that I was not fluent in English at the time. I had a hard time with conversation as well as understanding portions of some lectures. People in English speaking countries often do not understand the amount of work that goes into learning how to speak a second language fluently because unlike most of the rest of the world they never had to do it. English being the premier second language comes with great benefits for native English speakers. Learning to speak a language fluently is one thing, learning to speak it without an accent if you primarily learned it as an adult is quite another. A question I’ve gotten many times is ”why do you still speak with an accent?”. Well, Arnold Schwarzenegger certainly knows the answer to that question.

Another thing people in English speaking countries sometimes miss is that people in the rest of the world are often not as familiar with the culture in English speaking countries as they might expect them to be. Well at least that was the case back then. In high school I studied Swedish and Scandinavian literature, and a little bit of German, French, Italian, and English/American literature, but I did not know much about Shakespear or famous American authors, and if you think about it, this is not strange. In addition, I did not know much about American movies or American music, but that was because I, unlike most Swedes, had not paid much attention to English speaking culture and music in general.

Add to that, the fact that Americans do not know much about cultural phenomenon in the world outside of the United States. For example, most Americans knew nothing about the world’s largest music competition, Eurovision. Eurovision is the largest song contest in the world. Countries compete against each other, and the final typically has as many viewers as the Superbowl, about 200 million. Americans also don’t know much about the second largest comic genre (largest at the time) in world, the French-Belgian Bandé-Dessiné (Astérix, Tintin, Spirou, etc.). So, we knew different things and were used to talking about different things, sometimes leading to awkward situations.

Which brings me to handegg. What most of the world call football is called soccer here, whilst a sport in which you handle an egg-shaped object mostly with your hands is called football, when it should be called “handegg”. When I arrived in the US, I had never heard of American football, but I quickly realized that I better know something about it. Later in the year I went to an indoor football game with a friend in Madison Square Garden in New York. Indoor football is a sport that has almost vanished, but it was still a thing back then. Can you guess who was called down to the field to play football at half time? I was. I told the host that I was from Sweden and that it was the first time I held a football. He showed me how to hold the ball and announced that I was from Sweden and had never held a football. The crowd was cheering for me, and luckily, I threw the ball into the goal two times out of three. Our team did not win but I did well.


Which brings me to the fact that Americans are typically polite, friendly and supportive of the underdog. They communicate well, they say excuse me when they bump into people, they smile a lot, and are often good conversationalists. Americans can be loud and not everyone is friendly but in general most Americans are friendly. I think this is a good thing that I am trying to emulate but it was yet another thing I needed to learn.

One thing that might sound like critique is that Americans back then did not know world geography very well. Today’s youth seem to be a lot better educated in this regard. I should say that by the age of ten I knew every country in the world and their capitals, and I could say something about most of the larger countries. So, it was a little bit frustrating to me to speak to people who did not know where anything was. We met people who asked how long the drive from Sweden / or Europe was. A woman asked me where I was from and I said Sweden to which she replied, “is that where all the men wear skirts?”. I said, “no that is Scotland”. I believe that’s what she meant. Another woman asked me the same thing, and after hearing my answer, she said “Sweeting, that’s the name of your country? What a cute name for a country”. Or how about this conversation between the PhD advisor to a friend of mine and my friend’s boss:
Boss : My name is …, what is your name?
PhD advisor : My name is Bahram.
Boss : Baddam, that’s not an American name, is it?
PhD advisor : No, I am from Iran.
Boss : Iran I’ve never heard of that. Where is that?
PhD advisor : It’s in Persia.
Boss : Oh yeah Persia I’ve heard of that.

I overcame my culture shock, and we all did well at CWRU. It was a good year. Later that year I met my wife Claudia and with her I would experience a reverse culture shock a few years later. I was working for a Swedish robotics company, and we moved to Sweden with our oldest son for one and a half year. Not only did my wife have a culture shock but I did too, coming back to Sweden. How did that happen? Well, one reason was that in the US I had gotten used to a mix of cultures and ethic groups and Sweden is a very homogenous country. This mattered because through my wife, who is not Swedish, I got to know immigrants to Sweden. It is difficult to fit in when you are different and therefore immigrants tend to hang around other immigrants, so I learned to see Swedish society through their eyes, and I saw what I had never seen before. It took some time to get used to.


Have you experienced culture shock? How about a reverse culture shock?
I am originally from Sweden, but I’ve lived in Texas for more than 20 years and in the US for 30 years. Therefore, I forgot June 6, which is the Swedish National Day. It is still June 6 in California and Hawaii but not in Texas and certainly not in Sweden, so I am a day late. I forgot. A blogger who isn’t even Swedish incidentally reminded me. It is also a special National Day because it is the 500-year anniversary of Sweden’s independence from Denmark.

Christian the Tyrant, or as the Danes call him Christian the Good, was a very bad man who chopped people’s heads off. The Danish version of history is that Christian the Good was a very good man who tried to save the Union. He still chopped off heads though. Luckily, we had this guy Gustav Vasa (or Gustav Wasa) who resisted, and he became king of Sweden on June 6, 1523, which is 500 years ago. He was also really good at skiing.

Therefore, I have decided to post a couple of photos of the only Swedish Leonberger I’ve ever met personally, I haven’t been back to Sweden a lot. Her name is Amie, and she is from my neck of the woods, the high coast in northern Sweden. We met her at the top of a mountain, called the Skule mountain. Therefore, she is also the only Leonberger mountaineer I’ve ever met. To check out my original Amie post click here.


Amie was very happy and playful despite having climbed a mountain. Below is what Amie and we saw from the mountaintop.

I am also posting a few more photos from Sweden.



One thing that is pretty unique about Sweden is the different concept of private property. You can own the fruits of property, a farmer’s field, a mine, but the land belongs to everyone regardless of who owns it. Well almost everywhere, there are a few exceptions such as military reservations and you have stay at least 200 meters away from dwellings. It’s called “Allemansrätten”, or all-peoples-right translated roughly. This means that you can walk, hike, camp, pick berries and mushrooms, etc., anywhere without having to worry about trespassing. You just can’t walk off with the gold from a goldmine or a farmer’s crop. This is very different from how it works in Texas. However, everyone in Sweden love it and we certainly take advantage of it when we visit. In the picture below we were hiking, and we stopped at this small forest lake and someone had hung a tire from a branch.
