Space Humor

It happened long ago, in the dark ages of CRT monitors, when I first received a short forum message with :-) at the end. I stared at the message for a long minute(s) before giving up on decoding its meaning. It came from a well-respected friend of mine, so I responded with a short reply:

"What!?"

"You have to turn your screen 90 degrees clockwise." The answer came promptly.

My CRT was large and heavy, and it looked way too dangerous to tilt it that way, so after a little brainstorming of the problem, I concluded there's a better way of achieving the same goal.

I tilted my head 90 degrees anticlockwise.

"Aaaaaah!!!" I said promptly, and after realizing the picture, the big smile on my face slowly morphed into loud laughter. So I typed back:

"Wow!"

I didn't have to wait long for the next message:

"LOL!"

"What!?" I quickly copy/pasted my earlier message but realized I was too uninformed about new internet fashion, so I canceled the message and opened a new Netscape window instead, called www.altavista.com, and 'googled' new internet words. Ever since then, LOL has been at the top of my list of favorite acronyms. Along with all those cute ASCII faces. ;-)

In my case, and probably with many people as well, laughter is one of those most powerful cures for everything. The almighty vaccine for all diseases. Especially boredom and poor moodiness. LOL moments somehow come naturally with live social occasions and in movies, but in books they have one extra dimension. I really can't explain why that is. Perhaps funny moments in the written world often come unexpectedly and are more genuine. Take, for instance, Andy Weir's "The Martian." The hilarious parts in the book were genuinely funnier than in the film. At least with me... Well, nevermind that. So, to get to the chase, last month I read three extraordinarily funny books in the realm of science fiction and space exploration. So here they are in this short review, sorted by the count of LOL moments I had during reading. In descending order, of course.

The first one was "Where the Hell is Tesla?" by Rob Dircks. I stumbled on this one by accident, and boy, I am glad I did. Nikola Tesla is one of my favorite men in the history of people, science, and engineering, and here in Serbia, especially during my childhood, Tesla was idealized and always portrayed in a too serious manner. Anyhow, when I saw the title with Tesla playing the major role in the comedy story, I couldn't resist, and I didn't regret a single penny. It was by far the funniest book I read in a while. It had it all: decent science fiction based on cutting-edge scientific theories of the multiverse, the romance and friendship within different storylines, cute aliens, sci-fi battles of enormous proportions, great style of writing, Nikola Tesla in the most entertaining meaning of the word, and of course... Chip. I am not going to spoil the reading for you, but I will tell you this. On one occasion, I almost dropped my Kindle on the hard floor because of one of the strongest LOL moments. Enough said.

The second is "Jazz of Artemis." In the context of today's post, this is how I would name the book if I were Andy Weir. Of course, his new book is not a comedy per se. But it is not "The Martian" as well. However, in the realm of the funny moments, it is a decent sequel. Way better and much funnier. Jazz is... let me find the right word... an extraordinary girl on multiple levels. I enjoyed her adventures fully, and I do hope for the real sequel this time. I mean, with Jazz around, what can go wrong on the Moon? I really hope there will be a movie after this one as well, but not solely because of the entertainment part and all the LOL moments, especially with that Svoboda guy and his ability to manufacture various devices that do or do not belong to ESA blueprints and worksheets.

But seriously, what Andy Weir did with creating a fully functional city on the moon with both working technology and society organization is amazing and also extraordinary. It definitely deserves the motion pictures, and I am sure filming the movie that takes the entire story and action on the moon is another challenge. I am sure Ridley Scott is buzzing his mind with this as we speak.

Finally, and to use the cliché, last but not least comes the good old British humor. Something I grew up with was all the great TV shows like "Monty Python" and "Only Fools and Horses" or short comedy sketches and skits by Dave Allen, Benny Hill, Rowan Atkinson, and others. But in the flashlight of the parody novels, the throne is still with Douglas Adams and his "The Hitchhiker's Guide to the Galaxy". This was the first book I experienced LOL moments with, way before the LOL acronym was ever invented. "The Worst Man on Mars" by Mark Roman and Corben Duke was probably the most similar novel I read in a long while.

This is also a parody, but not really as much as its famous predecessor. This book follows plausible science fiction and doesn't go into wild imagination, like the restaurant at the end of the universe or "42". I really did like many technological backgrounds inside, like artificial intelligence or a space elevator, for example. But the humor with this one comes first, and the robots in their sitcom on Mars are something I do recommend warmly.

:-)

Super 8

The history of motion pictures dates back to the second part of the 19th century with photographers like Étienne-Jules Marey and Eadweard Muybridge, who, among others, were the first to take several images per second in one effort—all for scientific purposes back then—to study the locomotion of birds, animals, and humans. For example, Muybridge was the first to take a series of photographs of a galloping horse in order to prove that in one single instant of time all four horse legs are not touching the ground. More or less at the same time on another continent, Marey created a shotgun-shaped camera capable with one trigger pull of capturing 12 images in a row within one single second and storing them all on the single 90 mm film. He used his gun to study various motions of animals, fish, and insects within his so-called 'animated zoo', including dropping cats from different heights and filming them always landing on their feet.

ELMO Super 106, 8mm movie camera

It was not long after initial chronophotography efforts and enthusiasm in the 19th century that the 'evolution' of motion pictures diverted heavily into entertainment and cinematography. The history of films and fun started almost with the start of the 20th century, but in the spirit of today's title, 'domesticating' films within ordinary people and human homes waited another 65 years for the invention of Super 8, or, to be precise, the improvement of Kodak's standard 8mm film from 1932 into a more efficient surface with a bigger width for the frame itself and significantly smaller perforation on the film's right edge. After they introduced it at the 1964-65 World's Fair, Super 8 instantly became the very first home video format with light cameras capable of filming 18 frames per second and more than 3 minutes of the movie per small film cartridge.

To say that my father was a film enthusiast in the second part of the sixties and the entire seventies would be an understatement. It was natural for him to go the step further and, in addition to the several analog SLR cameras and darkroom equipment for developing photos, to invest in home movies. Spending time in the darkroom and hanging photos on the wire were some of the most thrilling experiences of my childhood, but when Super 8 came, another world opened. I was too young to operate the camera, but on the occasion or two I remember, I did hold it and press the red button, especially during our vacations in Greece. Well, aside from those rare moments, most of the time my job, with being a kid and all, was to be in front of the camera and not behind it.

Tondo Super 8 Projector and LG Nexus 5 in action

But to cut the story short, this month I did something I was delaying for a long time. During the last two weeks, every night I was descending into my own customized darkroom equipped with a tiny Super 8 projector and digitalizing our family films. Twenty of those survived over time, and with a speed of two per day, I projected them on the wall and filmed them all with my smartphone. It was far from being an ideal setting, but this was the best I could do. I tried different approaches, filming from different distances, using different settings, and using my DSLR Nikon in the beginning. I even tried to project the film directly into the DSLR, but all my efforts failed due to not having proper lenses and objectives, and in the end, the smartphone was the chosen solution, and it did a better job in the dark than the Nikon.

With more expensive equipment, I am sure the results would be much better, and probably the weakest link was the cute and old Italian Tondo projector, which was my father's portable cinematic projector. I did try with a bigger 'player' first, but despite all my efforts, I couldn't manage to repair the old and superb Crown Optical Co. Ltd. Auto-P, a silent Standard and Super 8 film projector, our primary projector capable of displaying big and crisp screens on the large walls and with much better quality. To be honest, it's more than half a century old and built with nowadays rare parts, especially the missing lamp that is hard to find these days, but I didn't give up, and perhaps in the future, if I stumble on some solution (read it: an eBay sort of solution), I will repeat the effort, at least for those videos filmed indoors.

Nevertheless, all twenty rolls now come with twenty MP4s, and for this occasion I decided to create two movie collages with six movies each. They are all filmed in the late sixties, during the seventies, and in the early eighties with an ELMO Super 106 camera from the first image. The first one, embedded above, contains six films from our early vacations in Greece, and in chronological order, they are filmed in the Acropolis of Athens, Zeitenlik, the World War I memorial park in Thessaloniki, vacation resorts in Kamena Vourla, Asprovalta, Katerini Paralia, and two vacations in the vicinity of the port city of Volos.

The second collage is from our home and village in Niš and Guševac in Serbia. Mostly it focuses on my sister's and my babyhood and early childhood, birthday parties, family gatherings, and excursions. Also our old house that is now gone and the old shape of our country village front yard. This video also contains one of the rare black-and-white films from our collection that probably originated from different cameras and settings.

This entire effort triggered lots of memories and emotions from almost forty years ago, and seeing people live, especially those that are not alive today, is something extraordinary that regular photography cannot induce. Perhaps we today, with all of our pocket gadgets, are taking video clips and home photography for granted, but before, in the Super 8 era, this was a completely different experience. What we today do with just two taps on the screen, before you had to do in a more complex manner, including purchasing film cartridges, carefully planning (directing) filming sequences for a 3-minute film, sending it to development, organizing cinematic sessions...

One thing is for sure: Super 8 was the origin of what we have now in our homes. It was eventually replaced with VHS tapes in the 80s, but at the dawn of the 21st century, the analog period came to an end, and old-fashioned home gadgets were replaced with home digital camcorders first and, in the very last decade, with smartphones. To tell you the truth, it is nice to have a camera in your back pocket, it is, but somehow, with me, as I witnessed the origin of the entire process in my early childhood, the nostalgia for the analog days gave me another layer of the entire experience. Something special and extraordinary for sure.

'Super 8,' a sci-fi movie by J.J. Abrams

Perhaps for the best conclusion for this post, it would not be fair not to mention one of J.J. Abrams' greatest movies from 2011. Simply named 'Super 8', it tells a main sci-fi story about an alien encounter, but everything is perfectly wrapped within a background story of school kids trying to film a short movie for a Super 8 festival. It was really a great movie, and if you liked E.T. before, this is definitely a decent sequel and one of my favorites.

Robert De Niro

While the short tale about the famous actor is itself a small historical record, especially for him and one little Serbian village half an hour away from my current location, I have to say that this post is a little bit mistitled even though De Niro's story has several connected points with what I want to write today. Instead, it will be about my grandfather and his war stories I listened to yesterday for the first time. Actually, my mother told me all this before, but yesterday, during our annual dinner, he was in a great mood to tell them himself, and this is my attempt to write them down while they are still fresh in my memory.

But, for a moment, let's get back to the title story. Not too long ago, I read in a newspaper article* about Robert De Niro and his European travels he did about 40 years ago, more or less in the time when I was about to be born. Back then, these kinds of tourist destinations were extremely popular among young Americans—if you were young and adventurous, you didn't need much money to visit most of Europe, traveling by foot and hitchhiking, meeting local people, living their lives for a summer, getting lots of experience, and filling your memories. In the case of a 25-year-old actor at the beginning of his career, this probably has more importance than with other people. Well, unless young De Niro was on some mission of seeking his ancestors, this is exactly what he was doing back then in the sixties when he ended up for a week or so in Čokot, the neighboring village where my mother was born and where my grandfather still lives in his nineties, enjoying life the same as when he was much younger. Yesterday he visited our house for a small celebration, and I took the chance and asked him whether this story was true and interpreted by the newspaper like it really was. To my surprise, he confirmed everything and also spiced it up with the fact that the family where De Niro stayed are actually our distant relatives living not so far away from my grandfather's house. He remembers the actor clearly, as he helped them to collect some vegetables and accompanied them to free markets where they all have been selling tomatoes, peppers, cabbage, and other food and vegetables. He said that De Niro, in his short visits, even picked up a little of the Serbian language and bonded with locals very well. Well, I am not going to spread this story any further; I just like to add that after last night I admire him even more. The other day I stumbled on a midnight projection of his masterpiece"Midnight Run" and enjoyed the movie again for the umpteenth time.

Ok, let's get to the history part and some half a century before De Niro's visits. Both of my grandfathers were about the same age when the Second World War happened. They both stumbled through this part of time in their early twenties and experienced it very differently. My father's father at the time was in the army when Germans captured his whole unit and transferred them all into a military camp in Germany. He was forced to do labor work the whole war there, and I hate myself because I didn't write down his stories, especially once, long ago, when he eagerly told us all his adventures, especially those in the days when the war was finally over and how he traveled back thousands of miles on foot along with thousands of people trying to cope and find their way home. Ironically, despite avoiding military fights during the war, my mother's father experienced it in an occupied country and was faced with imminent death a couple of times, and not only by Nazis! Obviously he managed to go through it; otherwise this blog would be just another 404 page. Following are his war stories that shaped his personality more than even he is ready to admit.

First World War**

However, in order to even try to understand his behavior, I feel like I need to add a couple of history facts first. After the First World War, Serbia was kind of a pillar of a new, fresh country where Serbians, Croats, and Slovenians joined and created the first monarchy of Yugoslavia. The Kingdom of Yugoslavia was formed in 1918 and exterminated by communism after the second war. The Serbian monarchy inherited it, and it was ruled by King Peter I and later by his son Alexander I. Despite being doomed to imminent collapse due to a vast amount of differences, the kingdom actually was pretty respectful in those days of Europe for its part in the First World War and many battles on the southern front, especially in Macedonian Greece. My great-grandfather took a big part in this war and was in the same lines with the king himself during their winter retreat at the beginning of the war. That was one of the most horrifying moments in the violent history of Serbian wars, but after many months and years of coping with the invasion of German, Austro-Hungarian, and Bulgarian armies, at the end our exiled army survived and returned to the battle by forming, to be proved later, a long-lasting alliance with French and British divisions, allowing them to finally move toward the end of the Austro-Hungarian empire and the very end of the first great war in Europe. However, even though the Serbian royal period between two wars flourished with the rise of democracy, free thought, and educational and civil rights, my grandfather didn't like it at all. When I asked him why, he told me just one story from his youth, describing maybe even better how old-fashioned tales from the 19th century were still there, opposing all the progress happening, especially in big cities. In the fall of 1935, after finishing elementary education in his village, he was so eager to move to a big city and start gymnasium—the best high school possible at the time (the same one I spent three years in during my teenage days, 50 years later). Yesterday, I swear that I saw a sparkle of a tear in his eyes when he was remembering how brutal was a man from the school who literally kicked him out of the school to the street, saying that he is not welcome simply because he came from a village with a big country estate and his place is not in the school, but rather his part in this country is only in the field doing hard labor in the cultivation of food. If you were a woman, it was even worse; there was only one school in the entire city encouraging young girls toward further education, but the quality of the education given there was questionable and not comparable to a gymnasium. My grandfather's disappointment rose even more later when he realized that living in the village had no benefits at all. All food manufacturers were at the mercy of greedy bargainers and dealers without any fair market or developed economics in the system. The villagers were simply second-class citizens.

Later, in the dawn of World War II, things were getting even worse. The rise of communist thought, brought initially from Spain and their civil war and also from the east and the first communist country established in Russia, polarized people in Serbia to the bone. The German occupation of 1941-1944 not only gave our grandfathers another wave of German and Bulgarian armies but also a full civil war between royalists and communists and their resistance movements. It was next to impossible to cope with all that if you were just a 17-year-old boy like my grandfather was.

I asked him what his most painful experience from that time was, and in the next half hour, he opened his heart and told us everything his young soul had to do in order to survive, and with an occasional wiping of a tear or two from his left eye, I finally learned how he eventually grew into a strong father figure and local community leader. Like today, back then Niš was one of the biggest cities in the former kingdom and as such was targeted by allies and their air force from time to time. Being just a couple of miles away from the main German command, Čokot was a natural point in air defense, so they spread heavy artillery in the fields in order to defend from allies' planes. One of them was settled in the yard where today is my grandfather's house. German soldiers slept in a nearby shack on, at the time, state-of-the-art air beds and shared local life with villagers. According to my grandfather, compared to Bulgarians that came later, they were all civilized men and paid for all the food they needed.

Also, there was one more important target in the village, and that was the national railway passing by on its way from the north toward Greece to the south, and Germans used it very often for deploying tanks and heavy vehicles and armory to the south fronts and even further to northern Africa. The local resistance was using that fact to stop the convoys and demolish the rails every now and again when they got informed of some important train passing by. In lack of people, for some tactical revenue, and to better protect it, Germans deployed young boys down the line in order to alert the army of possible attacks. During one night in 1942, my grandfather was one of them, and only by chance did he avoid death, as only a couple of hundredmeters to the north, resistance took action, and as a result, the whole train derailed that night. Germans killed on site all deployed boys along the line in retaliation. 1942 was especially cruel, as this was the year where fighting started to be more intense, the captives from the local Nazi camp performed a prison break that year, and it seemed that German command started to take resistance more seriously. Unfortunately, civil war also became more intense, and royalists, people who were basically leftovers from the dismantled Serbian army, and the communist movement started to fight each other with the same or even worse cruelty compared to all the German and Bulgarian occupations and their retaliations performed against both civilians and the resistance. Those years were the dark side of the whole Second World War in this neighborhood.

Air battle over Niš***

Faced by the fact that he almost lost his life, my grandfather chose to go low profile and continue cultivation labor with his father, going to the field, seeding crops, collecting food, and trying to live a normal life. It turned out that during the war this was not really possible. Even on the field they had that one experience where they just barely escaped and saved their lives when resistance started bombarding the German army from the neighboring hill. When they came back tomorrow, the sight was scary; blood and dead bodies were everywhere. I can only imagine how scenes like that leave a permanent mark on any witnesses, especially among young people and children. Anyway, in later years, the war started to fade out, and the winner and loser could be easily recognized. Communist resistance won their fight with royalists, and Germans started evacuating and leaving space for the chaos in the last years of the war. Like Germans before, communists saw the potential in all young boys in their early twenties and recruited them for the time that eventually came after the Germans officially withdrew. The young boys living in villages were easy targets; they were already bitter and disappointed in royal democracy before the war, and many of them saw their chance to get a more important role in the new society. Once again my grandfather was in mortal danger, and this time from upcoming communists. They were cruel. Even more than occupying armies. Especially toward those who were labeled as a threat for what they had in mind. In a moment I thought I saw fear in my grandfather's eyes when he told us what happened in the fall of 1945. In order to justify the full dismantle of the royal family and democracy, they organized a census. You can only imagine how elections were back then with no help of modern technology and no mass media to explain both sides. There were two wooden boxes, one to support royal democracy and the other to support communism for future state government. There were also rubber balls you had to put in one of those two boxes. You voted in a way that you had to put your hand in both boxes and leave the ball in one. Needless to say, official results showed all the royal boxes pretty much empty. Sadly, the truth was completely different, at least at the voting point where my grandfather was appointed as a monitoring agent. The voting day was coming to the end, and my grandfather and his peer associate started to feel some anxiety and fear of the final result. They chose to vote at the end of the day, and when they pulled the hand out of both boxes, it was more than obvious that the royal box was full of balls, while the communists scored almost nothing inside. They already received threats from the headquarters before the census, and what they did is maybe something you do only when you are faced with the most horrifying future. Instinctively, an hour before closing, they locked the door, broke the seals, and moved all the 'royal' balls into the communist's box. Then they reopened the voting again. The last remaining hour brought dozens of now balls into Royal's box, but the 'official' results were that more than 95% went to the new regime. Two things happened tomorrow. My grandfather learned that most of the other box keepers in neighboring villages were killed on site for the full royal boxes, accused of fraud, and persecuted without any trials. The second thing he realized was that he not only again kept his head on his shoulders but he was also commended and later became a mayor of his village, responsible for all big decisions, mostly by following orders from the 'above'.

The birth of communism in post-war times gave birth to the upcoming Cold War between the Soviets with their socialist allies and western countries. At the end of this war, my grandfather witnessed the air bombing of the city not only by the Germans but also by allies as well, even after the Nazis retreated. And even one real air fight that lasted pretty much about half an hour or so. In November of 1944, just about four weeks after Germans retreated from the city, over the western parts of the city of Niš and not far from the Čokot suburbia, happened perhaps one of the first US-USSR air 'encounters', and, as it seems, this one was one of the real and severe air fights with significant losses on both sides. In short, US fighters attacked a Russian convoy and killed many Soviet troops, including their general, who were progressing toward the north front. Soviet planes soon after attacked the US fleet in retaliation, and in the aftermath, Americans were forced to apologize in an official manner on the highest level. At least that is the official story. The main participants were the US Lockheed P-38 Lightning and the Soviet Yakovlev Yak-3. According to one eyewitness, and I am quoting the Wikipedia article, which you can find referenced, 'Soviet fighters flew over the old city fortress at an altitude of only 20m and attacked the Lightnings from below in a steep climb'. The final number of fallen crafts and deaths varies according to who you are asking—Americans, Russians, or Serbian witnesses from the ground—but they all agree that it ended in more than an ugly result with multiple aircraft fallen to the ground. The worst statement was that up to ten fighters ended in flames and were crushed.

Monument risen in memory to 'US-USSR Niš incident'****

The rest is the modern history of the 20th century. Communism lasted much longer than anybody anticipated, and the reason is no doubt the nuclear-based cold war with strong roots originated right there in World War Two. My grandfather was more or less satisfied with the new government. He recognized all its flaws and good sides, but from his point of view, especially thanks to those decades of prosperity back in the 60s and 70s and the fact that common villagers were treated better than in royal times, he enjoyed half a century in peace without any conflicts or wars. The only conflict he had in those times was, in fact, that he was a truly religious person, and religion of any kind was a major nemesis in all communist societies. Even though he never hid his religious personality, he managed to deal with this duality in his life during the entire communist era. Despite all the obstacles in the way, he even managed to play all the way and rebuild a small church in the village without being punished or suffering any major consequences from 'comrades in headquarters'.

We can only try to understand those violent times and how blood, animosities, war, and death can affect children, especially those who spent all their teenage years in dark shadows of our history books. Yesterday, by wiping the final tear, my grandfather finished his tales with these words: "Every night when I lie down in the bed in my dark room, there are only two of us, me and the god, and I always pray that I made good decisions before."

Solar Eclipse

The moon travels around the Earth in an elliptical orbit, and logically there are two points in its path where it is closest and farthest from us. Today it was in "perigee-syzygy" of the Earth-Moon-Sun system, or simply called "supermoon". Coincidentally, it happens that today it has the power to fully block the sunlight in northern Europe and make the biggest shadow one can make on Earth. In Serbia it only made a partial eclipse covering somewhat less than 50% of the solar disk. These are 12 photos I took in intervals of approximately 10 minutes from the eclipse start at 9:40 until it went away around 11:58. The biggest shade was at 10:48. We were pretty lucky today since nature gave us a clear sky with just one stubborn cloud that covered the sun-moon kiss around 11AM.

The above image is the composition of those 12 photos, which I took through our Sky-Watcher telescope with a solar filter. I still don't have a proper camera or adapter for taking astronomical photos, so I used our DSLR and manually took images. Therefore, photos are not ideal and perfect, so I used a little photoshopping to make them as clear as possible.

More about today's event in our neighborhood I found at timeanddate.com and tons of websites, as the media literally went viral this morning. No wonder, as the next partial eclipse in Europe will be in 5 years, and the next total one is not expected before 2026. Unfortunately, a total eclipse in Serbia will not be visible any time soon.

It sure is spectacular when our moon eclipses the sun, but in the celestial sky above, there are more events in the same fashion. I mean, situations when three solar system bodies become aligned, so to speak. In this update of the blog story about the classic eclipse, one of those I took with our scope on May 9, 2016. It was the transit of Mercury across the Sun, and the photo ended very well. I managed to catch one of those giant sunspots as well.

Scientific Copenhagen

Do you have that strange feeling when you are about to visit a new city abroad and are a little afraid of what you will stumble upon when it comes to simple things? Like how to use the metro line or how to buy a bus ticket or how to identify your next destination? Or how to book your flight back to your home? Or how to handle a simple dilemma: should you exchange the money to the local currency, or is it wise to put your card in every ATM or any other 'slot' machine on your way?

Hello™ at Microsoft Campus Days, 2014

Ericsson, a Swedish multinational provider of communications technology and services, has the answer for you. And me too. Last week, I took my entire family on the trip to Copenhagen for both business and pleasure hours in the Danish capital. During my previous visits I didn't have much time for tourism or any off-work activity for that matter. So I did a little research this time, and Ericsson's "Networked Society City Index" helped a lot. With the well-developed ICT infrastructure, economy, and social development, as well as environmental progress, Copenhagen is located in the top five within the NSC index, among 31 well-developed worldwide cities. After our visit we left Denmark with a feeling that everything, or most of it, went perfectly smoothly and the applied IT was extremely helpful, simple, and useful. Unified communications (UC), integrated into people's business life from within smart gadgets and laptop computers, were also a big part of it, and I can proudly say that, in a way, I took part in the active development of Rackpeople's* Hello™ for Microsoft® Lync®—UC software that integrates with Microsoft's Lync and Exchange and presents video conferencing within a single click on a wide variety of screens and devices. The business part of last week's Copenhagen trip was to visit Microsoft Campus Days, where Hello™ had a big feature presentation and successfully presented what it can do in the current edition. From the developer's point of view, I have a good feeling that this project will have a long life with plenty of room for more versions in the future, especially if Skype and Lync integrate and create space for non-business users as well.

However, Copenhagen, besides the business side of the medal, has plenty more to offer. History, arts, sport and music events, amusement parks, museums, royal and naval sites, shopping streets and malls, restaurants, walks along the canals, sightseeing from the sea, and many more, but this time we chose to glimpse the city's unique scientific side. With a seven-year-old boy in our small family, along with me being a big fan of science and skeptical of society, our stay was really special. If you add last week's Black Friday hysteria, which brought an enormous smile on my wife's face all day long, I can safely say that we spent one of those memorable times you never forget.

The Rundetårn, a 17th-century astronomical observatory**

The very first day we went to see Rundetårn, an almost 400-year-old observatory built by King Christian IV after the first major success of naked-eye astronomical observation of planetary motion, performed by famous astronomer Tycho Brahe. His incredibly accurate measurement of 6 planets motion at the time was used by Johannes Kepler after Tycho's death in 1601, and for the first time in astronomy, three laws of planetary motion were established, including the one that all planets in the solar system move in elliptical orbits with the Sun at a focus. Even though there are still suspicious thoughts about honest relations between Brahe and Kepler and even uncleared circumstances related to Tycho's death (traces of mercury in hairs from his beard were found in the 1901 autopsy), these two colorful characters of the early 17th century made crucial contributions to our understanding of the universe, including the discovery of Newton's law of gravity, which was a direct outcome of Kepler's laws.

Anyway, the Round Tower in the heart of Copenhagen is still active and one of the oldest functioning astronomy observatories. The dome is 6.75 meters high and 6 meters in diameter and contains a refracting telescope with 80–450x magnification with an equatorial mount. Without an elevator or stairs, walking up and down its unique 209-meter-long spiral ramp that spins 7.5 times is something special I never saw before. Not to mention we had the opportunity to look through the 'scope with two very friendly astronomers who warmly welcomed us and patiently answered all the questions we had.

Apollo 17's moon rock

The next stop in our astronomy tour was the Tycho Brahe Planetarium. It is located not too far away from the observatory and hosts 'The Space Theater' with a 1000-square-meter dome-shaped screen, and seeing a giant 3D Earth rotating in front of you or 30+ meter high mammoths in "Titans of the Ice Age" is the experience you don't want to miss. They also hosted an "A Journey through Space" program and permanent exhibition with meteor specimens and one of the largest moon rocks from the Apollo 17 mission (in the above image).

Science is not science if you don't experiment in the lab, and to have at least a feeling of what scientists do on a daily basis, you have to visit Experimentarium City. The main exhibition last week was "The Brain", with tons of posts waiting to be explored and played with. Needless to say, my favorite was the game with the cool name "Mindball"—in which you have to push the ball only by using brain wave sensors. The more you are relaxed and focused, the more it will get into your control and move in the desired direction.

Mindball—moving the ball with brain activity

If you like to have your brain scanned and to see which part is activated when you move fingers, or if you want to see really cool optical illusions, or to learn more about scientific facts and how stuff works, or to play memory games, or... simply to experience a great family time, visiting Experimentarium City is mandatory.

Finally, no trip to Copenhagen would be allowed to have the adjective 'scientific' in the title without visiting the national aquarium and the zoo. Opened last year, Den Blå Planet, National Aquarium Denmark, located near Copenhagen's airport in Kastrup, is something you would need to see to believe. Especially if you came from a continental country like Serbia. Equally interesting was the zoo, which went viral earlier this year when they decided to euthanize Marius, the young giraffe, because of a duty to avoid inbreeding, approved by the European Breeding Programme for Giraffes. Right or wrong, it is not mine to say, but we humans are responsible for the health of the animal life, and at least it is a good thing that there are scientific organizations that are taking the breeding of animal species seriously. Anyway, perhaps the best impression in both the wild animal and fish exhibitions, to me, was their climate-controlled environments—in the zoo their "Tropical section" with jungle climate conditions, and in the case of the aquarium, it's the "Amazonian region" with tropical plant life, strange-looking fish, and lots of piranhas.

The Little Mermaid

Finally, I want to thank all my coworkers at Rackpeople for having a good time on and off the office, especially Lasse, who invited us for a visit and gave me the opportunity to spend my yearly bonus in Copenhagen. Trips like this are also a great opportunity to learn more about the country and region you are visiting, and I mean not just about the sites, history, monuments, and other attractions, but also about people, hospitality, and friendship. Sometimes, the result is more than you hope for... sometimes less. Perhaps the best advice when you are visiting abroad, no matter if you are doing it as a pure tourist or within a business agenda, or both, is to leave high expectations at home. Nevertheless, Copenhagen is one great corner of the world, more than worthwhile to visit, and this scientific side I wanted to show in this post is something not many cities in the world can offer.

Flat Sausage Fair

Approximately 15 years ago I was working as a lab assistant in the programming department of microassembly and object-oriented languages within the College of Applied Technical Sciences in Niš, Serbia. I was engaged with all five semesters and was teaching students from their freshman year to graduation, and every now and again, along with the board of professors, I was asked to attend their final exams, followed by a sort of social celebration in the form of a small festivity with a table full of food and drinks.

On one such occasion, a student who came from Pirot, one of the biggest cities of eastern Serbia, asked us if we had ever tried before a sausage called "vitamin bomb", which, he said, was one of the oldest delicacies from the region he came from. I spotted that one of the professors, who was actually known to have tried almost everything when it came to food and drinks, started nodding his head, but it was clear that the rest of us heard it for the first time. The student looked at the professor and said, "I am sure you never tasted this one," and pulled out from the bag a ... well ... something that looked exactly like a "horseshoe" in both shape and color. I glanced toward the professor who claimed that he tasted it before and saw that even he was surprised with the strange-looking sausage in the student's hands. The student glimpsed the same, warmly smiled, and explained to us what it is and how it's made. Today, almost two decades later, the "vitamin bomb" sausage is a recognized brand, and the simple translation from Serbian "Peglana Kobasica" is "Ironed" or "Flat" Sausage. Last year, the town of Pirot and its tourist organization created the first "Flat Sausage Fair", and yesterday, despite poor weather, we decided to visit the second fair made in honor of this great Serbian soul food, which is the mutual name for all those old recipes that survived centuries in their original forms.

But what is so special about this sausage that it earned its own fair?

The recipe is not the secret, although this is not a meal you can make in a couple of hours in your home; with a little enthusiasm, it is doable, and results could be extraordinary. From what I can find online, you need a great selection of various quality meats (cleaned and stripped of all fats and unwanted parts), ultra-finely chopped or minced and mixed with spices (up to 2% of different chilies, 2% salt, 1% garlic, and 1% pepper, followed by other suitable spices according to your taste). No water or any other liquids are welcome in the mixture. Now comes the interesting part. After filling is ready and wrapped into eatable natural sausage casing, sausage should be formed in the "U" shape and left for drying on the draft. The drying "chamber" must be very cold, with an optimal temperature around zero degrees or colder, with as low humidity as possible, and in the presence of great frost, keeping outside water from vaporizing in great scales. Usually with a bottle, sausages are pressed and ironed two or three times a week, after which they take the form of a horseshoe. Ironing is necessary for most of the unnecessary air and water to be ejected from the sausage, which ensures longevity. Needless to say, they are purely organic with no preservation of any kind, no additives or artificial colors, no heat treatment, and no exposure to smoke.

Since there is no strict recipe when it comes to ingredients, it is clear that with different mixtures of various meats and spices, they come in a wide variety of different tastes, and given the fact that they are made of and the nature of the preparation that has not changed from the times dating a couple of centuries before, in my humble opinion, I have to say that I haven't tried better sausage yet. And believe me, I have tried many. Even those advertised on large scales, like the white sausages of Bavaria or great Danish delicacies you can buy outdoors, are simply not worthy rivals. Furthermore, the energy value of the sausage is very high, and it is usually served in small dosages and sliced into tiny, a couple of millimeters chopped pieces. Best of all, due to the fact they contain almost no water inside, you can store them in a deep freezer, where they keep their original taste and shape even after a couple of months. Yesterday's fair was, like the year before, organized very nicely and with thousands of people browsing and tasting the specimens. We bought a couple of kilos of different varieties with different meat mixtures and spice ratios, and the winner for me was a hot, whitish, extra tasty brand. It was moderately hot, made out of four different kinds of meat (besides beef, they used the best parts of goat, horse, and donkey meat), and with a great mixture of spices. The casing is giving this particular one a whitish color, which is also pretty cool and unique.

Unfortunately, because of yesterday's weather and half a meter of snow outside our weekend house, we couldn't get to the fair earlier and see its social side, so I am including the video I made last year. Somehow and also to my taste, the jazz band playing last winter fits greatly to this particular fair and the advertising product.

Celestia, Campfire and Astronomy

I remember every little detail from that weekend trip. From the very first moment when we stepped into the bus that took us to the mountain base, throughout the rest of the first day when we climbed down into a small cave with narrow hallways toward the small chamber at its end. I vividly remember the glorious, endless, and hard-to-find second cave we stepped in the very next day, followed by an overwhelming feeling and little fear when we passed through cave chambers, cutting the darkness with handy tools and small flashlights. I will always hate myself for not having a camera to capture the surrounding scenery when we traveled by train later that afternoon, which looked like it came right out of the 19th century with wooden benches rolling the railways slower than Usain Bolt. All those rock formations and abandoned train stations were slowly losing their battles with nature and were looking exactly like a background from Sergio Leone's spaghetti western movies.

But what I will remember the most is the first camping night between the caves. It was an extraordinary experience only a campfire can provide.

It was the hot middle of the summer, and the forest was mysterious and kind at the same time. I don't remember the exact year, though, but it surely was during my late teenage years, most likely in July or August of 1987. Along with a couple of my peer friends, I was lying down in the middle of a forest clearing on top of my brand-new sleeping bag, hypnotically staring toward the nightly sky. I glimpsed the watch and saw that midnight passed just an hour ago. The campfire was vividly glowing around the small glade surrounded by dark trees. It was the perfect time, and soon it was about to begin. As planned, the first one came on schedule, leaving a straight line in the sky for a millisecond or two. Shortly after, another one fractured the nightly sky, then another one and another and another...and then it was a shower. The Perseids. The icy fragments entering the Earth's atmosphere every summer are body parts of the comet Swift–Tuttle, which travels in this neighborhood every 130 years, providing lots of meteors for our camping TV. That particular year we planned our adventure by the moon's motion, or, to be precise, we wanted to go on the trip when there was no moon in the sky most of the night during its crescent phase. Without light pollution from the Earth and the Moon, the sight was amazing—perseids, thousands of stars, nebulas, galaxies and planets, the Milky Way in the center of our view, planes, and artificial satellites passing by throughout constellations with their leader of the time—the Russian space station "Mir", which was probably one of those brightest moving dots we saw that night. If you didn't see such a sight, you would be surprised how the night sky is actually dynamic. If you add to the scene strange sounds coming from the surrounding forest made by sleepless birds and wild animals, you get perfect entertainment for the big portion of the night. It was our first camping trip, and the fear of the unknown a little spoiled the event, but in our defense, without any experienced guides or team members, I can assure you that every suspicious sound that came from the forest sounded like the ultimate wild predator hungry for young humans. Anyway, little because of the fear and much because of active heavens, we finally fell asleep a little before dawn and successfully slept for an hour and a half, ready for the next day.

Space station Mir (1986-2001)

That really was one great summer, and this trip would stay on top of my adventurous history, from many perspectives. But it wasn't the one that triggered my interest in science and astronomy. I couldn't say what it was for sure, and probably, among many things, at the very beginning, it was one scientific toy my parents bought for me when I was really young. It was one toolkit box**—an optical set of plastic parts and various lenses allowing you to build different gadgets such as a microscope, binoculars, a spyglass, a kaleidoscope, a diapositive magnifier, prism tools, etc. It was my favorite toy for many years. The other equally important trigger is my failure to comprehend the word "infinite" and my everlasting desire to understand its meaning. It was bugging my mind ever since I started to look up at night. Even today, after dozens of courses of various mathematics I had to pass during my high school and university education, infinity is staying the biggest unknown, lying right there, far beyond my scope. There were years in my youth when I was convinced that infinity actually doesn't exist at all. I loved the idea that the cosmos is curved to 360° in all directions. I desperately wanted to believe that if you go with your spaceship straight up, eventually you will reach the same spot only from the opposite direction, just like the surface of Earth and its two-dimensional fully closed curve. Of course, today within the mainstream scientific thought there is much evidence that the expansion of our universe is real, but still it doesn't solve the infinity of it. At least in my mind. Even though the probable fact that our universe is just a part of a multiverse neighborhood where our cosmos is expanding into something bigger, to me it is only stretching the infinity out, only this time far beyond our borders. Maybe one day we will find the definite answer.

From the other perspective, if we are looking at the 'infinite' trouble only from our rational mind, we have to admit that the human race is extremely young, evolutionarily speaking. The real handicap is that we are living in a 'finite' world. Everything that surrounds us has its beginning and the end. At least it seems so, and even though we today learned a great deal about our position within the celestial realm, we only scratched the surface of it. We only managed to set a foot or two (or 12 to be exact) on the Moon, and we only started to explore our own solar system. Due to our own limitations in the form of our unwillingness and hesitations to deal with the unknown and/or our own animosities for each other in the form of militant behavior throughout our history, this is still a very slow process, but inevitably, one day, in the not-so-far future, the time will come when, lackingenough energy to sustain humanity as we know it, we all will have to start looking up, not for searching for the divine but for our own pure survival. Then our own evolution will speed up and skip some gears toward answers to many inconceivable questions.

Night Sky and Perseids by Brad Goldpaint (Goldpaint Photography)*

Anyway, astronomy is one of few scientific playgrounds simply because it contains many unanswered questions. There are plenty of proposed theories that will surely stay in their theoretical phases for many years until we finally get ultimate proof. It is entirely based on studying electromagnetic radiation we are picking up on the surface of Earth and several instruments in orbit. All possible frequencies within electromagnetic radiation are telling us many stories from its origin point and the path it is traveling through. Of course, studying full spectrum requires big and even large instruments in both size and money needed for their manufacturing. Especially if they require being lifted into orbit in order to avoid atmospheric disturbances. Secondly, it is amazing what must be done in order to look up one particular spot in the heavens simply because everything in the cosmos is in motion. We need to solve the rotation and revolution of the planet and, if posted in orbit, compensate for the extremely fast speed of the spacecraft carrying the instruments. As the monitoring object is farther away, the less amount of radiation is picked up by the sensors, so astronomy is one of those indirect or asynchronous sciences where we need to collect the data for some time, which could be years or even more time, and then for an equally considerable time analyze the data, compare the resulting images, and conclude science out. For example, take the Kepler orbital space laboratory. It orbits the Sun following the Earth in order to get a clear view toward the monitoring stars, and it is simply continuously taking images of 'nearby' stars (about 145,000 stars) and sending the data to the Kepler team for analysis. Over time, the team and their sophisticated software measure slight brightness changes during possible orbits of potential planets, and only by these small changes in brightness of the main star is it possible to roughly determine the size and orbit of the planet causing the dimming of the light from the star. However, in order to get all those facts out of the data, Kepler must take lots of images and cover the planet's full orbit. That means in order to confirm the planet, Kepler must take at least two images separated by time in order to confirm the revolution time of the planet. It's a slow process, and considering lots, and I mean LOTS, of received data, I am sure we will hear about more and more planets found by this technique.

Among all possible wavelengths within the full electromagnetic spectrum, the coolest one is the one situated between infrared and ultraviolet waves. The greatest visible light. The one we can see. Even though it is just a tiny portion of the full spectrum, this is the one we can enjoy with our own eyes. This is the one we see every night we look up toward the amazing heavens. Thanks to relatively cheap optical instruments, we are able to enhance the view and zoom it in and see further. Some time after I enjoyed my optical set toy I mentioned earlier, I got my own first refracting telescope. It was small without any tripods and fully mobile, but looking at the moon for the first time was something I will always remember. Discovering the fact with my own eyes that Venus, like the Moon, also has phases and seeing it in its crescent shape was the next best thing I experienced. I still have it, and every time I grab this small piece of optics, I can't help myself and instantly remember the times when I was fixing it on the ladder positioned on the top of our garage and spending hours looking toward the stars.

Transit of Mercury over Sun by Sky-Watcher 150/750

Today I have in my possession an educational reflecting telescope with a respectable mirror size and focal distance mounted on an equatorial tripod along with a motion tracking system capable of fixing the spot on the sky for hours. Unfortunately, amateur astronomy requires lots of free time, which I regretfully don't have enough of. In addition to a lack of free time, watching the heavens requires an unpolluted environment, and life in big cities is beneficial for everything but astronomical observation. Sometimes I feel like that character from the Michael Keaton movie—I don't remember the title now, but in the movie he found a way to clone himself in order to get finished various tasks in his life... Similarly, I would like to have one me for work, one for astronomy and science, one for family and writing... Simply, the day is too short, and to support the family and life, the work is always number one. But it is a good thing to have spare moments and spend them in the most enjoyable way. Even today, from time to time, I point the scope up and peek a little. Sometimes I take photos out, like this one of Mercury transiting the Sun disc.

To conclude with some short 'observations', if you want to do some amateur astronomy, you will need star maps. Before they were black and white and printed in the form of atlas books. Today all that changed with the speed of the internet and graphic tools on the average personal computer. They are all online, and you can access them with many apps. I recommend 'Celestia' and 'Stellarium'. Even without a real telescope, they provide endless fun.

Childhood

I am watching my son grow up every day, and from time to time I can't stop thinking about how childhood occupies a special place within all memories acquired in everybody's life. I tend to think that this is not because we memorized childhood better than any other period of life; it's more that, compared to adolescence and later times, those moments are pure and clean, with not much tension, conflict, or seriousness of adult life. This is all about playing, learning new things, and enjoying pleasurable moments and events, and we are simply programmed to maintain nice memories better, while others not so pleasurable are stored deep in remote regions of our brains with a tendency to be quickly forgotten.

Hairdresser Shop

Today one small visit to the hairdresser triggered the extraction of some really nice memories from my childhood. This morning I took a walk downtown for some errands and decided to take some shortcuts through a couple of blocks where we lived most of my childhood. It was an old house my grandfather and his father built a decade or so after the Second World War, where we lived in a ground-floor apartment while my grandparents were situated a floor up. It was a house with a very nice front yard full of trees and flowers, and in the back were small ancillary buildings, garages, a workshop, and a miniaturized chicken roost where my grandmother produced nice, fresh, domesticated eggs. Chickens too. She was a master of preparing chicken soup from prime ingredients, meaning killing the bird, taking off all the feathers, taking out all the inner organs, and cooking the dish at the end. I remember once I had to catch a runaway chicken that slipped out of my grandmother's hands and escaped to the front yard—all that without its head. Ok, that wasn't one of those nice memories I wanted to share in the first place, but still a proud boy's experience not everybody can share. That said, let's get back to the main story. Our house was, not so long ago, torn down, and a new residential building was built on its foundation. This morning, following my route to downtown, I walked into the street where our house was and saw a new hairdresser shop in front of a new building along with a new bakery shop next to it. My hair doesn't require much maintenance, but yesterday was also the summer solstice, also known as the day when I cut my hair to summer length, so after little hesitation, I decided to stop by.

The main room was located (coordinately speaking) in the same spot where our living room was 40 years ago when I was the age of my son now. All the memories all of a sudden started to emerge, even those vivid images of the room back in time. I was the only customer, and I sat on the chair in the same spot where our old black and white TV set was placed, and perhaps one of the immediate emotions was created by the memory of the day when my parents bought a brand-new, state-of-the-art color TV set. I remember it barely fitting the old TV spot in the large living room cabinet. This was a change comparable with nowadays switch from old small CRT television sets to large flat LCDs, only with more enthusiasm simply because today we take modern innovative gadgets for granted more than was the case in the past.

Then and Now

In the middle of the haircut, the hairdresser was interrupted for a couple of minutes, and instinctively I glimpsed the rest of the room in all directions, and maybe even for a moment I was able to see the past. All the mirrors, the hairdresser gear and tools, chairs, waiting room, and photos on the wall started and faded out in front of my eyes and morphed into our small table, two armchairs, and a couch my father made along with many other pieces of furniture in other rooms. I also saw the kitchen, the big dining table, the old big telephone in the corner of the hallway, and the iron bunk bed for my sister and me, positioned exactly 5 meters away from my current position and located in the bedroom or within the next-door bakery shop, as in today. I was proud of my upper bed, where I spent lots of time as a boy, especially during winter times. This was also the playground for us kids, where we were doing homework and also performing Johnny Weissmuller's jumps from the upper bed down to my parents double. Summers were different; almost every suitable moment we spent outside in the front yard garden, where we used to have dinners and meals at the big round stone table under the cherry tree higher than the house itself. I was able to cross from one tree to another like a small monkey, and later, when I got a little older, this was my clubhouse where I used to read comics and magazines. I remember once I twisted my ankle in school and got myself a leg immobilizer for three weeks, which I spent entirely under the cherry tree in the special temporary bed my mother made for me. I was deeply touched when my complete class from school came to visit me the first day of my school absence.

We moved to a new house when I was about 11 years old, but that first decade of my life will always stay the most memorable of them all so far. The plot where the front yard was located is still intact next to the new building, but all the trees are long gone along with all the magic I experienced in there. One of the events I also remembered today was a night we spent in the open in that very front yard after a big earthquake happened in Romania back in the year 1977. There are lots more memories of that period in time, but I will stop here. After all, this is not a book of memories or anything; just a small flashback popped out of my head today. I also didn't include many covering photographs in order not to spoil the words, just these three portraying the place now and then. The first image above is the hairdresser shop taken by my smartphone, and I am sorry you can't see my state-of-the-art and ultra-fashionable haircut because of the flashlight, but I kind of did that on purpose. However, I will be returning here and not just for memories from my past but also because of great service, and I mean it fully when I let somebody carry scissors and sharp tools so close to my head. Seriously, I once had a bad experience with a sharp razor having a close encounter with my right ear, and from that time I am always having chills and goosebumps when I need a haircut. The second photo I made out of two images of the same spot. Left is me around the year of 1972 (perhaps a year or two later, but I can't be sure), and in the background you can see part of the house with two windows that are now hairdresser and bakery shops (shown on the right).

Batteries not included

So there you go, I might have been a little bit emotional in this post, but having a public journal like this is maybe why I started this blog in the first place so I could be able to remember and write about interesting events in my life I stumble upon from time to time.

The Little Mermaid

I am wondering if is it possible to combine, in just one blog post, a short story about one country, one modern IT business, several great friendships, air flights, professional challenges, and friendly people everywhere you look. I know the answer is probably no, but I will try anyway. Let's start with an easy puzzle: if you thought of The Little Mermaid and Hans Christian Andersen, quantum mechanics and Niels Bohr, the famous Hamlet's "To be or not to be" in Shakespeare's old play, and amazing cuisine with cookies, pretzels, Carlsberg beer, and Legos? The answer, for a very few of you who didn't guess, is, of course, Denmark. One of the top developed countries of the European Union. According to the United Nation's first-ever World Happiness Report from this year, Denmark has taken the top spot, followed by Finland, Norway, and the Netherlands. When I first read about this, I was skeptical since happiness is a relative thing and I am sure all people in the world are equally happy and unhappy from time to time depending on daily moodiness and events that drive us.

The Little Mermaid

However, now after my second visit to Denmark, I tend to change all the skepticism and maybe better understand the global happiness or social happiness, if you will. According to the study, one of the conclusions could be this (and I am paraphrasing the report): "While basic living standards are essential for happiness, and after the baseline has been met by the majority of people, social happiness varies more with the quality of human relationships than with income." Simple truth with no simple explanation, but if you ask me, I think that the history of any society is deeply embedded into everybody's DNA, and as long as it is not filled with lots of conflicts, wars, animosities, and hard times, the better human relationships become.

Several years ago, around the time of the birth of my son, I started outsourcing for a Danish consulting company within a team of developers providing coding in the Microsoft .NET environment for various purposes. A very big number of Danish companies are using Windows servers and other client-server solutions for their businesses based on the Microsoft environment, and according to my humble opinion, I fit in nicely due to my expertise and experience in the field in general.

The Rackpeople Team

Actually, contrary to most other jobs, being involved in IT development, more than having various degrees and initial knowledge, requires the ability to change and learn the new stuff. The technology is changing rapidly, and after more than five years of telecommuting, when it all started with simple web applications, we are currently involved in more sophisticated technologies like Lync and SharePoint development, connecting them with the mobile world and providing the right information at the right time. All those activities are followed by financial subsystems centered around Microsoft Dynamics C5, equally challenging from one developer's point of view. I remember the days back in the 80s and 90s when developing business software was completely different compared to the present day. This is no one-man show anymore. The complexity of the IT support, consulting, and development reached a higher level of understanding, and I mean for both sides, developers and customers. Even though I am outsourcing about 1600 kilometers away from the office, this would not be possible without internet, daily communications, reporting, solving puzzles, audio and video conferencing, brainstorming, and live meetings. The dynamic IT world is also affecting consulting companies, and five years is a very large period of time for all of us as well, so recently, as a result of last year's merger, the old/new company continued joined efforts within new surroundings and teamed up for future challenges.

Not so long ago I visited my friends at Rackpeople for a couple of meetings and some other on-and-off work activities in regard to future projects and also for simple socializing with the guys and some brainstorming sessions in a local brewery house (where else do brilliant ideas come from?).

Baltic Sea between Poland and Denmark

Of course, like any business trip, the best part came after work hours, where the office environment was replaced by the "Custom House" restaurant and an "ice cream" walk along with the brewery house in the 17th-century Nyhavn district at the end of my visit. This is part of Copenhagen you don't want to miss. I still can't choose what was the best: American classic steak, delicious ice cream in domesticated cones, or perfect draft beer. Regarding the whole event from a sightseeing point of view, what maybe impressed me the most was the sun still standing very much above the horizon while the local clock tower was showing 22 hours and a change. It was the cost of living on a round Earth so much north away from the equator. I enjoyed very much the sightseeing while driving through Copenhagen, visiting the famous Little Mermaid, and most of all our talks about lots of different topics. With this blog post I would like to thank Jesper, Claus, and Mark for an amazing evening.

I am not a frequent flyer, but every now and again I am using air traffic, and maybe now is my chance to write about my experience flying in a south-north straight line between Belgrade and Copenhagen. This last flight was pretty much smooth without much turbulence, probably because the weather was more or less the same during the whole 1600km long trip. However, two years ago I was taking the same flight during the hot summer, and the weather wasn't the same in the beginning of the flight compared to the last half hour and the descent itself. The moment the plane entered the Baltic Sea from continental Poland, the weather changed dramatically for the worse. I remember I was having a wing seat and saw the jet engine start seriously vibrating up and down. It was pretty scary, but the crew did not pay much attention, so I reckoned it was pretty much normal. The other travelers weren't so calm, especially one older lady that had to use the oxygen mask after landing, which was also a little disturbing, as the plane needed to take a couple of sharp turns at very low altitude in order to align with the runway. One more thing also attracted my attention, and this is how clean and spacious the Danish capital, suburbia, and small towns in the countryside are. Due to lots of rain over the year, everything is green and very compelling.
