Looking back on 2017

Like in the last years here comes my yearly recap. Older flashbacks can be found for 2016, 2015, 2014, 2013, 2012, 2011, and 2010.

When looking back on 2017 I realized that one of the main themes was that I finally had time to dive into some things. This was not a conscious decision, but rather something which just happened. In the previous years there was always too much work for university etc. to really get into some topics. But now I have e.g. mastered coffee, which is a huge enrichment for my quality of life. For the past year I got very much into brewed coffee, read a lot about it, visited barista courses, tried a lot of different coffee beans and ways to prepare the coffee. This happened basically each morning for the entire year and even whilst travelling I carried the Aeropress and a ceramic mill. At some point we ended up with the Chemex and a coffee bean from a little roastery in Porto which we discovered when travelling in Portugal and some other equipment (such as a very good coffee grinder). I’d say that I now have the best fitting coffee for my taste. It’s really nice to finally have time to put a lot of energy and passion into mastering something.

Cooking is another ongoing (probably life-long) project. For the last couple of months I have cooked for usually five evenings of the week. This has resulted in a constant optimization of some dishes and I am very happy with some things that I cook now. One of the side dishes that I usually do is a green salad in order to balance the main dish and I am very happy with the tweaks and ingredients I have established now. I can reproducibly prepare a salad that I am very happy with. The same goes for some other dishes and baking bread, which was also one project of “mastering” something.

In terms of technology, I think 2017 was a great year and I’m very excited about 2018 technology-wise. Just look at the myriads of use cases for machine learning which appeared in 2017. That’s crazy, at one point I had the feeling that there was something new and incredible each week (this youtube channel contains a lot of interesting works). The developments surrounding reusable rockets and SpaceX and some of the blockchain startups (I like Colony) are also very exciting. Of course a lot of stuff is overhyped, but it’s still exciting to be immersed in this scene.

Travel-wise I had a nice time in Israel, Portugal, Amsterdam and some nice parts of Germany/Austria. City-wise I have the feeling that I got a bit more comfortable with Berlin in our second year here. Some things which I really enjoy are the vast amount of different restaurants, fine-dining options, interesting people, international crowd (half of my colleagues are non-German), concerts of distinguished and non-major artists, theaters, courses, electronic music clubs (I can’t emphasize this enough), and conferences (I attended the TechCrunch Discrupt in December).

Good ideas
Placing a “Use soon” basket visibly in the kitchen and put stuff in it which should be consumed soon. This can also serve well as a reminder to use up certain things which are always forgotten.

I finally became a vegetarian. This was a natural development and in the last years I ate less and less meat. A while ago I stopped cooking with it altogether. When travelling I was always eating vegetarian since a long time. My main reason for going vegetarian is of ethical nature. In the last months I even ate vegan for most of the time, I stopped buying milk, butter, or eggs altogether some months ago.

Quotes which stuck

Some worry that an artificial consciousnesses could turn against humans. I am not concerned about this. […] It seems that intelligence and abundance comes hand-in-hand with empathy. Humans, more and more, are peaceful creatures. An increasing number are so empathetic that they avoid eating animals entirely. If a super intelligence could outsmart me, then it would also understand all that I’ve outlined above about how fragile and rare life is. A super intelligence would, I think, be super empathetic.

Interface is a metaphor for information.
    —(from an OP-1 presentation by one of the founders)

Intimacy is the process of […] inviting others in to have a look around.
    —Charles Foster, Being a beast

Statt uns ein Gefuehl von Sicherheit zu geben, koennen uns Gegenstaende belasten und hemmen.

I continue to believe that we can be the generation that ends disease, ends poverty, and stops climate change.

Minimalism isn’t about having less. It’s about having only the things that add value to your life.

In Wahrheit ist jeder Wunsch, dem wir nachjagen, eine Belastung.
    —Pia Mester

Ask yourself: What would it be simply ridiculous to not have in 30 years time? Then go make that.
    —Alan Kay on startups and ideas

In a world run by blockchains, decentralisation could be pushed even further, to include objects. Once they have their own identity and can be controlled via a blockchain, it is possible to imagine them becoming, in a way, self-determining. A few years back, Mike Hearn, a former bitcoin developer who now works for R3, a blockchain consortium, suggested the idea of self-driving cars which are also financially autonomous. Guided by smart contracts, they would stash away some of the digital money they make by ferrying people around, so as to pay for repairs or to replace themselves when repairs are no longer worthwhile. They would put themselves in long-term parking if not enough rides are to be had—or emigrate to another city. They could issue tokens to raise funds and to allow owners to get part of their profits.”

Interesting articles
Ryan Dahl, Optimistic Nihilism

Oh My Gosh, It’s Covered in Rule 30s!

This section in the Wiki article on Survivorship Bias was an eye opener.

I really like packaging lists, such as this one.

Oskar introduced me to Simpsonwaves — mashups of old simpson series enhanced with old VHS effects and underlied with Vaporwave music. Perfectly fits my taste of music & style :-). Here is one great example.

Spotify says that Nocow and Lorn are two very popular electronic music artists of mine.

Good Videos
Stephan recommended the Brothers Green cooking videos and I took quite some inspiration from them. I especially cooked the (vegan) stir fry described in this video a lot.

Movie which rang the bell most/Movie which reached me most
Weit. I got this movie recommended on festivals and from friends. The movie is emotionally capturing and really nice, it’s a documentation and all of it has happened that way. The story is that of a young German couple (from Freiburg) who decide to travel east for as long as they need to make it around the world. They hitchhike, hike, take the boat, etc. (but never the plane). They recorded a lot of this journey on camera and cut it into this movie. The movie is quite professional though and was a surprise hit in German arthouse cinemas. It’s definitely worth watching and will give you wanderlust :-).

Blade Runner. I re-watched the original and it’s impressive how well the movie still holds up.

Hell or High Water. Great movie with a great pace.

Best photos that I took
I’m happy with most of the photos that I put on this blog, these are some which I were very happy with in 2017:


I’m also very much satisfied with portraits I made of some other people close to me, but I don’t want to post them all here.

Last years new years resolutions
My new year resolutions last year were:

  1. Buy maximum 5 clothing items. ✗
    Oh oh, the first resolution and I have to admit that I failed miserably :(. Unfortunately I couldn’t resist and bought way more new clothing items. This was mainly due to discovering some nice stuff when travelling, but also due to the discovery of a very nice custom tailor here in Berlin and the techwear brand Outlier. They both hooked me!
  2. Cook a new meal each week. ✓
    I (and Valerie) did it! Quite often it was even more than one meal. My top new dishes were: homemade granola, vegan bacon (following this recipe), marinated champignons, hummus + baked eggplant + pomegranate, and marinated brussels sprouts.
  3. Learn more Spanish and don’t lose all the stuff learned in South America.
  4. Finish up some old, half-finished projects. ✓
    I mainly had the video interview with Elf Pavlik in mind and I finally finished and published it.
  5. Phone more with friends. ✓
  6. Donate more. ✓
  7. Make one publication. ✓
    I did, but this work dates back to my time at university and it just took a long time for it to get published. So hmm…I originally had in mind to create a new publication when I put this resolution up.
  8. Get rid of more stuff, keep striving for minimalism. ~
    Hmm. Sold a lot of stuff, gave away a lot of stuff, threw a lot of stuff away. But also bought some new stuff. Ahh this is difficult. I really would like to be there: only own the stuff that contributes value to my life. I read so much about this and I admire the people who live out of one bag so much. It’s a journey and I’m making a constant effort to downsize. Still I own too much stuff and the worst thing this year was that I went nuts with clothing items.

New year resolutions for 2018

  • Spend less money.
    I went a bit nuts in 2017, in 2018 I want to spend less and save more. That’s my number one new year resolution. As a first starting point I want to gather a detailed overview over all my expenses and want to meticulously document every cent that I spend in January.
  • Consider meditation again.
  • One additional, regular fitness exercise.
  • Bring photography skills to a level that I am satisfied with (i.e. a more serious level). Specifically by thinking more about composition and getting better at it.
  • Contribute more to open source projects.
    In 2017 I contributed a bit to two smaller projects on GitHub by fixing some issues and doing a bit of enhancements, it would be nice to contribute to more projects.
  • Start a technically challenging new project.
  • Develop my own clothing style further.
    I like it a lot to analyze clothing and think about the way others (or I) dress. Here in Berlin I very often see people which have found their unique style, it seems to me that some of those people really wear their look. They have found an idea which they want to convey and they just nail that. Especially in Neukoelln (where I work) I see a lot of people who fit this description. I also strive to achieve a level where I feel that every clothing item which I wear fits very well into the complete picture. I am not entirely happy with the status quo though, since I am currently very much interested in two different styles of clothing: the techwear direction with materials such as Dynemma and companies like Outlier and the — kind of opposite — direction of classical clothes which remind of the suits/skirts from the 60s/70s with e.g. pleats on the pants or rougher materials like wool or linen.
  • Decide fast, don’t overthink.

Books in 2017

Books I read in the last years: 2016, 2015, 2014.

2017 was a very book-intense year. It has the all-time high of number of books read since I write these posts. I think the only time that I read more was as a teenager. But at that time these were mostly easygoing works of fiction, so nothing comparable to the stuff which I read now.

One of the reasons for this peak is that I travel by subway to work basically each weekday. My workplace is not far for Berlin (~30 minutes from door to door), but in total that already makes ~30-40 minutes reading time each day for the round trip (with one subway transfer). I have heard from other commuters (at least from Markus) that they experience this reading peak as well. Another reason is that I am no longer occupied with university lectures. At university I always read a lot of papers and science literature as part of my studies. This is gone now and I read more books instead.

Ray Kurzweil — How to Create a Mind
Basically Kurzweil postulates that a lot of research on how the brain works goes into the wrong direction. He makes the case that a lot of elaborate findings (e.g. the relativity theory) were made by people sitting in nature and “just” making logical conclusions. In his opinion a lot of the brain research gets lost in details and fine-grained examinations of biological micro-details, thus missing out on the big picture. Kurzweil makes the case that a large part of the brain basically follows an elaborate pattern matching algorithm. The book was an interesting read.

Robert Macfarlane — Karte der Wildnis
The book is published by the German publisher “Matthes & Seitz Berlin” who has a series of natural science books. I discovered them by chance in a bookshop two or three years ago and wanted to buy one of their books ever since. The only problem was that this series consisted only of extensive books on insects, donkeys or e.g. trouts. As much as I loved the high quality and typography of the books, I just didn’t think I would be able to finish an extensive book on donkeys. But then I discovered that they published notes of Robert Macfarlane on his search for wilderness! Thus I immediately bought the book. The optical appearance of the book is immensely good. The typography is done very very well, the paper is of very high quality, the book is thread-binded, all pages printed in two colors, etc.. It really is a joy to just flick through the pages.

This book itself was a kinda strange read for me. It’s really different from other books. It’s not really a story, but a mere collection of descriptions of wild places which the author found. Instead of describing his inner feelings he mostly describes the places themselves and paints them with words. This is also reflected in plain chapter titles like “Moor”, “Forest”, or “Valley”. There is no climax in the book and I think it would go against the overall vibe and intention of the book if there were.

In the beginning I found the book very hard to read and get into. In the end it was easier for me. As Markus put it: maybe this is one of those books which I should read again in ten years time.

There are some really nice descriptions of wilderness which the author found, places in deep forest, untouched by humans, with lots of animal caves, wild nature, skeletons, etc..

Kein Ort hätte besser meiner Vorstellung von reiner Wildnis ensprechen können, wie ich sie zu Beginn meiner Reisen hatte. Eine räumliche Logik hatte mich hierhergeführt, der Wunsch, an einem Punkt zu sein, an dem sich physische und geografische Höhe summierten, ein hoher Gipfel auf einem hohen Breitengrad. Jetzt aber wollte ich diesen Ort nur noch verlassen. Mich überfiel ein noch stärkeres Unbehagen, als ich es, ebenso unerwartet, schon auf der Felsnadel von Coruisk verspürt hatte.

Douglas Preston — The Lost City of the Monkey God: A True Story
The book is a bit like Jurassic Park in real life and tells the story of an archaeological expedition to locate a rumored city in the jungle of Honduras. The author is a journalist (for National Geographic) who accompanied the scientists. I can definitely recommend the book, it was a very thrilling and interesting read and one of my reading highlights this year. Besides the archaeological highlights it is an interesting account on corruption, grave looting, and the dangers of a jungle.

Brian Jay Jones — George Lucas
This is an unauthorized biography on Lucas. I don’t really like those unauthorized biographies, since they often tell “from hearing”. The same goes for this book. Overall, I think, he is not portrayed as a good filmmaker. To me, it was not really conceivable from the book why he made it as far as he has. I think the book portrays Lucas as a stubborn director who succeeded only because other people helped him decide what’s good and bad. There are often mentions of how he shot a picture or wrote something which was so chaotic (or incoherent) that other people had to help him sort things out.

The book was interesting for the whole history facts, but I was missing emotional insights or glimpses into his characters. But this is just typical for unauthorized biographies which lack access to intimate friends of the subject or, even worse, the subject itself.

Bov Bjerg — Auerhaus
I found this book by chance in a small hostel in Jisr az-Zarca in Israel (there is only one hostel there). It’s a German book and on the first page a “Beatrix” had placed a paper with a note that all of the book had actually happened in a small village near Stuttgart and that she grew up there. This got me interested and I started reading the first pages — three/four hours later I was finished with the entire book, it got me hooked so intensely on those first pages. I didn’t put it down even once and in the end my eyes hurt. But it was definitely worth it.

I really enjoyed the book. It retells a summer in the authors life. One of those summers which will never come again. The book captured me emotionally and I could identify a lot with some of the themes — especially the melancholic mood of looking back on a very happy time of living together with friends. The book captures this spirit very well. Also, it is set in a small village between Ulm and Stuttgart and refers to some places familiar to me.

Christian Rudder — Dataclysm
This is a book by one of the co-founders of OkCupid, he describes statistical insights which he gained whilst building the platform. OkCupid works in a way that you answer questions on all kinds of things…your view on the world, or character traits which you have and which you search for in a partner or friend. The main thing which stuck with me from the book is that even though you can answer thousands of questions on their website they could already predict astoundingly well how likely two people were to get along from these three questions: Are you interested in politics? Do you like horror movies? Have you ever traveled to another country alone?.

Rolf Potts — Vagabonding
Found this one on a flea market (the one in the princess garden in Kreuzberg). It’s a book on the authors experiences and tipps on vagabonding. The topic spoke very much to me, but I found the book bored me and it was a bit hard to finish reading it. I think this was because I am already quite familiar with the topic and most of the stuff from the book I had already heard or talked about a lot of times.

One thing which stuck was a suggestion of how to describe years of work-free vagabonding in a CV: honestly describing where one went and what one took from it — e.g. being able to look after oneself in a remote country, being patient, getting along with all kinds of cultures, etc..

Bov Bjerg — Die Modernisierung meiner Mutter
I was so enthusiastic after having read “Auerhaus” that I was eager to read the one other book by the author. The summary spoke to me: short stories on his childhood in a small, swabian village and on his “exile” in Berlin. However, I was very much disappointed by the book and finished it purely to get it over with.

Antoine de Saint-Exupéry — The Little Prince
A shame that it took me that long to finally take it up and read it. Very good book. I think despite of what the illustration style suggests it’s much more of an adult book then a childrens book.

Ramez Naan — Nexus
It’s hard for me to describe how exceptionally good I found this book. I think it’s an extremely visionary and outstanding book. The author really grasps some of the ideas surrounding transhumanism, their applications, and their influence on society. Some of the recent startups in this field (Neuralink, Kernel, opnwatr, ni2o, …) may very well end up building the described technology.

The book is science-fiction, but of a very near future, not too far away. It is set 15-20 years in the future and makes an, in my mind, very plausible extrapolation. I think the disruptive technologies described in the book are plausible and it is highly likely that this is how our world will look in a couple of decades. Be it two or ten decades, this technology will appear sooner or later. You can really grasp it! It’s a glimpse of a future that might well come to be. It’s not science-fiction of intergalactic space wars — it seems to be not that far away, but totally groundbreaking.

Whilst reading the book I often had to stop myself from consuming it too fast. I wanted to prolong the reading experience :-). Often I made pauses and thought a bit about what I just had read.

I especially liked the scientific base of his book. It is very much apparent that he is a computer scientist, his depictions of this realm are very accurate (the Unix stuff, the algorithms, the peer reviews, academic conferences, etc.). Also I liked that he mentions Vipassana meditation and a couple of places in e.g. Thailand where I had also been to. His depiction of Bangkok is pretty much how I remember it as well. I think some of the other stuff which he describes is also pretty authentic and he knows very well what he is talking about.

The book is written in a very visual way and it’s easy to imagine this being made into a movie at some point. Overall I was surprised that this book is so little known in the cyberpunk and trans-/posthumanism scene. I liked it a lot and it has become one of my favorite books. It re-ignited my interest in this whole topic of neocortex, transhumanism, neural enhancement, and brain computer interfaces. It provided a glimpse of a future that I haven’t seen prior to the book. I think it’s very probable that something like the technology he describes will be invented in the next decades.

Ramez Naam — Crux
Naam actually wrote a triology: Nexus, Crux, Apex. I was so very hooked and enthused by the first book that I immediately went on to the second one. The second book is fantastic as well and I liked it a lot.

Ramez Naam — Apex
The third book was also a nice read, it’s a good book, although as with most trilogies: the first one is the best.

Ramez Naam — More Than Human: Embracing the Promise of Biological Enhancement
The Nexus trilogy got me so hooked on the whole trans-/posthumanism scene again, that I immediately continued with this non-fiction book by the author. He describes the state of research in terms of genetics, cloning, neural augmentations, and related domains. He makes an elaborate argument for progress and enhancing human nature. He also describes counter-positions and typical arguments of opponents. The book was a very interesting read and in my eyes makes a valid and probable prediction of how the future will evolve. It was also nice to see counter-positions examined, he makes a very positive case of evolving humans and fostering scientific progress.

Helmut Herold — Linux-Unix-Shells
Markus lent me this book a while ago, when I was attending the course “Systemnahe Software” at university. I’m a bit ashamed that it took me quite some time to pick it up and read it. At some point the guilty conscience was too much and I took the opportunity of big-day-off to read through it. Big-day-off is a thing which we have at work each six weeks; I can do whatever I want for two days, as long as it is loosely related to the company — most importantly it doesn’t have to yield any business value. I decided to take this time to deepen my shell knowledge. I skipped the chapters on ancient shells. The rest was informative and brought some stuff up from memory again (null operators in bash, why certain commandos have to be built-ins, etc.).

Sam Williams — Free as in Freedom
Another book which Markus gave to me some (unfortunately) years ago. The guilty conscience was too much as well and I finally attacked it. The book is the biography of Richard Stallmann. It gave a bit more insight into his person and I think I now understand a bit better what his motivations are. The book goes into depth on for example the difference between the terms “GNU/Linux” vs “Linux” and “Free Software” vs “Open Source”.

After I read the book I found out that there is a derivative work in which Stallman — who was dissatisfied with some of the authors depictions of him — changed things around and wrote comments indicated with “RMS: ” below anecdotes, quotes, etc.. Hmm. I’m not really sure what to make of this, but I think it’s a bit over the top and only reinforces the impression of Stallmans urge to micro-manage. It’s a bit ironic that the book actually makes a point of describing this urge quite well.

Samin Nosrat — Salt, Fat, Acid, Heat
The book is a meta-cookbook. It consists mostly of four large chapters: Salt, Fat, Acid, and Heat. Each chapter examines the impact of this ingredient on a dish with the authors main message being that these are the four variables that effect a well-done dish the most.

The books main impact on me was to buy the best salt and olive oil which I could find and to experiment more with varying these variables when cooking. It also reinforced my opinion that the best way to learn cooking is to cook a lot.

Airen — Strobo
The text on the back cover says “the book is experienced in ecstasy and written in ecstasy” and this is totally fitting. I mainly read the book because of my own wanderings in Berlins electronic music clubs.

Airen — I am Airen Man
The book is more mature in literary terms. Its content is the authors time in Mexico and it’s mostly a continuation of “Strobo”. There were some passages which I reflected on for some time.

[…] einer, der sich von so ziemlich jeder Erfahrung ferngehalten hat. (p.59)

[…] wenn all die Küsse und Umarmungen nicht zählten, dieses verschwitzte Lächeln nicht echt wäre, wenn das alles nur eine Dummheit war, ein paar Sünden am Wegesrand, dann sage ich Ja zur Dummheit, Ja zum Leichtsinn, denn nur diese Küsse zählten, nur dieses Lächeln war echt, nur dann und dort habe ich gelebt. (p. 145)

Alexander & Ann Shulgin — Pikhal
The autobiography of Alexander (& Ann) Shulgin. A couple years ago I took interest in his person and read a lot about him. At that time I had also bought the book and now finally took time to read it. The part written by him about himself was interesting to me, but I disliked the part written by his wife (which from my feeling is about five times larger than his part).

Following the death of his mother and griefance of his father:

Finally, I said Enough! Let’s all go on some sort of short get-away, to give ourselves a chance to repair. Where should we go? It didn’t matter, I said; I’ll take care of it.

So my father put a clean pair of socks and a change of underwear into a satchel, and all four of us set out for San Francisco, supposedly headed for San Diego. In actuality, unbeknownst to my father, I had arranged to have the house sealed off for a long absence, and I’d gotten tickets on the P&O ship Chusan for a trip, not just to San Diego, but past it to Panama, then to Trinidad, Barbados, the Canary Islands, England, and on to France, where we would stay for a year. […] The plan worked. My father had to buy a whole new wardrobe; he re-established contacts with Russian-speaking friends whom he hadn’t seen for a quarter of a century; he completely severed himself from his grief-obligations, rediscovered his identity and his energy, and he later remarried, opened a restaurant, and lived another fifteen years.

Hunter S. Thompson — The Rum Diaries
The book is a nice account of Puerto Rico in the 1960s. I liked the whole journalism lifestyle which is depicted in it. It was a nice read and I’d like to read more of his works.

So overall I get to 20 books, seven of them were written in German, the rest in English.

Analog Multiple Exposure Photography

I have been experimenting with exposing film multiple times. The idea is that instead of winding the film forward after having taken a photo you take another photo (or multiple ones) in the same place — making the photos overlap. These are some of my results.


Short Trip to Portugal


Went there with Valerie for just a bit over a week in May. We stayed in Lisbon for some days, which I perceived as quite a nice city with a unique vibe and architecture. I liked that people were so calm and relaxed. We met up with Marina in Lisbon and spent a nice time with her.

I was surprised that Portuguese is actually a very different language from Spanish. I found it remarkable that words are different when a woman says them opposed to when a man uses them. For example, the version of “thank you” which females use is “obrigada”, opposed to the male version “obrigado”. The expression “thank you” is of course so ubiquitous that it is used in all kinds of contexts: advertisements, door signs, websites, etc.. But I only ever saw the male version “obrigado” in these contexts, which makes me implicitly mentally read and associate this with a masculine voice. It’s crazy how deep gender segregation runs here – it is even deeply manifested and reflected in the language. I think this will make it very hard for the culture to detach from gender stereotypes and to adapt e.g. trans-/crossgender ideas.

After Lisbon we spent some days in Porto. I didn’t get that enthusiastic with the city, a bit too many tourists, too much stress and too much noise. Lisbon on the other hand was more chilled out. Still, it was a nice time and I perceived the Portuguese as very friendly. We had a nice time trying the different fabulous vegetarian restaurants there. The prices usually are a bit cheaper than in Germany, so for 14-16 Euro per meal you get an extraordinary restaurant where you will be served with white gloves and stuff, comparable to a high-class, top-notch German restaurant.

For one day we went to a smaller city called Aveiro and visited Marina there. Quite a nice city, nice conversations, nice time.

Even though it was just a bit more than a week, it was still nice to travel for a bit. Especially since I haven’t been to Portugal before. There is always stuff to discover and we had a lot of fun trying various famous Portuguese pastries. One evening we were in a Cafe late in the evening reading some books. They had some cake left, which they didn’t want to spare till the next day. So they surprised us with it :-). Stuff like this is nice and somehow tends to happen more often to me when travelling. And I always enjoy the feeling of coming home, getting a hot shower and putting on some completely fresh clothes (and not the ones which have been in the backpack for days). I think that’s probably in my Top 3 things about travelling: Coming home again :-).


Elf Pavlik & Moneyless Living

About five years ago Elf Pavlik visited me in Ulm for a few days, when I was still studying there. He voluntarily lives without money since 2009 and shared my interest in free software and (at that time) open data. I found his lifestyle very interesting and we spent a few days together and I took this opportunity to ask him an infinite amount of questions. I recorded some of these conversations and had always planned to cut them together and put these recordings online. For various reasons I didn’t do that for five years. My main reason (which seems a bit silly to me now) was that I had owned my camera only for a short period at that time and was unsatisfied with the way how some of the material turned out. But now I finally did cut a short clip from it! You can see the result here:


Moneyless Living / Elf Pavlik / Ulm 2012
(the original file can be downloaded under this link as well).

It was very interesting for me to see how different worldviews can be and meeting Pavlik definitely had an impact on me. Pavlik told me about his further travel plans; he had planned to first travel to Paris for a few days, then Lyon, then to Italy to visit some people and then further somewhere else. I found this quite remarkable, he wasn’t constrained by finances in any way. Money just didn’t play any role for him when planning where to go next (or his life in general). This is in stark contrast to how many people would e.g. plan a trip to Paris (train tickets for probably 100-200 euros, booking an accomodation there, etc.).

Also, my dorm refrigerator was never this full during the whole time I lived in this apartment as it was during the time when Pavlik visited me (because of dumpster diving). Certain things which he said (often casually, when talking about something different) stuck with me as well. Sentences like “what some people consider borders” and other thoughts which are mentioned in the video as well.

Backpacking Israel


For two weeks of March I was backpacking in Israel. I flew there from Berlin and met up with some friends in Tel Aviv. I think this is the shortest vacation I had since a couple of years, but my work life constraints me in these terms now. Still, it was nice to travel again. Being able to float around, staying here and there, talking to people, taking photos, reading books, thinking about stuff.

Israel has been on my travel wishlist since a while now. Such a unique country; I’m never really sure how to grasp the whole Jewish culture. It seems like some mix of culture, religion, country, tribe. And the political situation makes for a very unique mindset of the people and their view on e.g. airport security, life, their country, etc.. If you have the time just read the Wiki article on the Six-Day War, it seems like a story straight out of Hollywood.

One of the things I enjoy most when travelling is to get up early in the morning, walk around in a city, sit down somewhere, get a coffee and breakfast, not doing much, just watching the city wake up for hours and hours, ordering another coffee, maybe read a bit, observe some more…chilling away the entire morning.
In Jerusalem I couldn’t sleep well and woke up very early in the mornings all the time. So I just walked around in the empty old city by myself. On the last day I ended up in the Jewish district at some kind of plaza and stayed there for a while, just watching the city wake up. In Jerusalem the unique thing is that on early mornings many orthodox Jews go to the Western Wall, return home and then go to work. It was somehow nice and calming to just sit there and observe this scenery.

There were some memorable conversations which stand out. One was with a woman of about my age. She studied at about the same time I did. I talked with her about the way the Israeli war with Gaza in 2014 affected her studies at university. The war had a major effect since her exams were always postponed due to attacks and she always started learning anew. That was quite a unique perspective.

The other conversation was with an 18-year old girl at a hippie gathering. She was very, very much full of life. I think I now understand why people tend to age slower when surrounded by young people. When I asked her about what makes up her mind she got quite emotional and talked about making art in order to feel like being alive. The things she said subsequently and that whole manner of having the immediate, very pressing urgency of creating something was a character trait which reminded me a lot of myself a couple of years ago. In the subsequent days I thought a lot about this conversation.

We visited a number of cities, with Tel Aviv standing out to me. What a vibrant city! Full of life! Seems quite similar to Berlin in the summer. Restaurants and bars halfway on the streets with loud non-mainstream music, many young people, alternative vibe, interesting people.

Israel is such a small country and travelling around in the Bus is cheap and easy. Wherever you go, it’s never far. We at most had bus rides of 2-3 hours. We also hitchhiked for a bit, which was really easy (even easier than in Germany). I was surprised by the Sabbath, which is taken quite seriously. Each week, on early Friday afternoon, most shops, restaurants, supermarkets, transportation facilities, etc. close down until Saturday after sundown.

Other stuff which stood out to me was the West Bank. We went to Bethlehem and I was surprised by the height of the wall, it is much higher than the Berlin wall was. And sadly it’s not just a relic of the past there, but rather an active part of everyday life there.

Besides those bigger cities we were also in smaller ones — Clil was a small, laid back town in the North with a focus on sustainable living. The houses there are off the grid and you can buy fresh homegrown vegetables directly from gardens. We did some hiking there and cooked each evening.

We were also in a town near the Sea of Galilee. A guy in the hostel there approached a friend and me, he said we looked like “fresh out of India” and that there was a hippie gathering at a river somewhere nearby. Of course we went there :-). In the past I have been to similar events in Mexico and Guatemala. It was very nice to attend something like this again. Music, families with children, vegan food, community kitchen, nice conversations, easy to talk to people, a place where you can take some time off from the real world out there.

The co-existence of two different cultures in one country is interesting to observe. It is a bit sad though. There seems to be little assimilation or effort to bring the Arab and Jewish culture closer together. In the majority of cases even schools are separated. It seems obvious that it’s hard for adults in both cultures to live peacefully together when they grow up separately from childhood on.

Another city which we visited was Jisr az-Zarqa, a 100% Arab village at the coast (the last Arab village at the Israeli coast). This felt a lot like being back in Morocco. Jisr has one of the highest (if not the highest) school dropout rates in the country (the criminality rate is similarly bad). We stayed in a hostel there and the host had to calculate 5% discount for us. He took a calculator and did this in a very complicated manner with a lot of intermediate results (instead of calculating “price * 0.95”). I guess it’s hard to see the value of education if most of the people you know don’t see it as well. There are few role models with a good education. Timo currently does his Ph.D. in a niche area of realtime systems on the intersection of computer science and electrical engineering. It’s already hard to describe his research to many people in Germany, but to explain what he does to people with such an early school dropout rate would be so alien to their view on the world that I can’t possibly imagine how they could form any understanding of the subject. I think education is really important to enable these people economic independence and reduce criminality and even though there are now a myriad of tools (Wikipedia, Khan Academy, Duolingo, Coursera, etc.) available, the bigger and more underlying problem here might be that people just haven’t learned to see the value of it.


One Bag Israel


If you’re a bit into travel blogs, minimalism, one bag philosophy, vagabonds, or digital nomads you will soon stumble upon one of those packaging lists where people elaborate on the stuff they take with them when travelling. I like to read those lists, considerations, and reflections. In this post I have compiled one such list for a short, two week backpacking trip to Israel.

In similar lists and reviews I have sometimes read stuff like this (original quotes):

Comment on an extensive packaging list for a trip to Asia:
Thanks for sharing! If you were to look back, would you have taken less?
Actually built this over the last year, but haven’t gone on the big trip yet…

I don’t understand how you can compile a list of tips for stuff to take with you or review a product without having actually used it? So, well I have written this post only *after* I actually went to Israel. I have included some names of products in the post, though I did so hesitantly and only for stuff which I found worth mentioning.

  • Map with documents.
    Copy of health insurance, list with addresses of family/friends, copy of vaccination records, biometric photos, international drivers license, address and telephone number of German embassy, pen + some plain sheets of paper, blood donor card (it contains information about the blood group).
    The vaccination records are required by some countries to let you immigrate and even if they don’t require them, it’s still a good idea to have them with you in case of emergencies. Biometric photos can be required for all kinds of things (in India for a lot of stuff, e.g. to buy a SIM card).
  • 30 USD.
    Since a while I always carry 30 USD as immediate cash for emergencies when travelling (e.g. when I can’t find a working ATM). In all foreign countries where I have been to it was always extremely easy to exchange USD to a native currency. I usually also have some Euros in cash with me.
  • A small, watersealed bag with various small items.
    Rope (to make a clothes line), clothes peg, gaffa tape, Sugru (formable glue), power converter, Smartphone + charger, lighter, pocket knife, lock, flashlight (Fenix LD12), backup battery for flashlight, small mirror, case to store glasses, ear plugs, flexible strap (to e.g. attach stuff to the backpack).

    Also I always have some fresh waste bags with me. They can be used for all kinds of stuff: to wrap liquid stuff and prevent it from leaking, wrapping flip flops before putting them inside the bag, as a way to collect clothes from the washing machine, or — of course — as a waste bag.

    Since a while I always have foldable coat hangers with me, they are quite small and it’s easy to hang stuff to dry or just to let clothes gain some fresh air.

  • Large Microfiber Towel.
    Lightweight, dries fast.
  • Something to eat.
    Nuts or a muesli bar (a Cliff Bar usually). Something which can survive heat and being buried in the backpack. I found it calming to always know: I have something to eat with me. For example, if there are no shops open when arriving somewhere I will still have something with me. For long bus rides it’s also comforting to have something small as a backup.
  • Analog camera + 5 films + throwaway camera as backup.
    I separate the used from the fresh films by storing them in two different, small, labelled vacuum bags (Noaks Bags). The films should always go in your hand luggage (see this site of Kodak on why).
  • One long trouser (which I wore), one short one (which it was too cold for), one swimming trunk (which it was also too cold for). Some shirts, sleeves, underwear, a normal jacket, and a lightweight, foldable rain jacket.

    I usually don’t take thick pullovers and instead go for a layered approach of wearing multiple layers when it gets cold. This way I need to carry less stuff. I usually have some Icebreaker merino shirts with me, they are very comfortable in hot and cold climate and they dry fast. Also: wherever I go, I always take long thermal underwear with me. And I always carry a scarf and a hat. Even when it is hot, bus rides or train rides might still be windy. Carrying a hat is easy, it doesn’t have a lot of weight or take a lot of space — but if you’re cold a hat can already help a lot, since your body evaporates a lot of heat via the head.
    I always have two vacuum bags with me (by Nordisk), in which I store all clothing: one for clean clothes and one for dirty ones. The vacuum bags keep them properly separated.

  • Flip Flops.
  • Kindle.
    An eBook reader has an immense value to me when travelling. Sure, books have their pros, the feeling of reading a worn-down, color faded paperback is of course nice. But books also take up a lot of space. In previous journeys I often went through 2-4 books and they were often taking up way too much space. One time I had a book with me and realized after a couple of pages that it wasn’t working for me, I then put it away and went on the sad search for an appealing alternative in Thailand’s outback. The Kindle solves all these issues and I think the pros outweigh the cons.
  • Foldable, lightweight backpack.
    For walking around in the city and not having to carry the bigger backpack everywhere. I use one by North Face (the Flyweight) which has a clever feature: The pouch (in which it is kept in the packed state) is integrated in the backpack in a nice way when it is expanded; it then functions as a theft protection pouch, since it isn’t easily accessible when someone unzips the backpack.
  • Foldable, lightweight blanket.
    I used it for picnics and sitting at the beach.
  • Some medical stuff, band-aid, rubber gloves, something against insect bites.
    I store these things in one vacuum bag as well.
  • Ethnotek 46l backpack + rain cover for it.
  • Bag with toiletries, handkernchiefs, and sun protection.
  • Wallet.
    Two credit cards of different providers. Organ donor card.
  • Passport.
    The most important thing last :-).

That’s it. Not that spectacular, but that’s how it should be. Minimalistic. I quite enjoy that it takes me maybe 5-10 minutes to pack everything up when leaving the hostel. I have reflected over each item and thought about why I take it with me.

And now the list of all the things I should have taken ;-):
I didn’t take my hiking shoes with me, but I should have. It would probably have been best to solely take them with me, but I don’t really like the style of them when walking around in cities or going out in the evenings.

Looking Back on 2016

As in the last years here comes my recap for 2017. Older flashbacks can be found for 2015, 2014, 2013, 2012, 2011, and 2010.

Best Decisions
Taking a couple months off to travel. I am very happy that I managed to write a series of posts whilst travelling. This was the first time that I blogged whilst travelling and it was a different experience; whilst writing the texts the memories were still fresh and the feelings present.

Going Analogue. Haven’t had my digital camera in the hands since I got a professional analogue one. It’s a very nice experience to have this moment when you unwrap the developed photos, already having forgotten half of the motives. I enjoy this a lot.

Stopped reading news sites. I think this is a natural path following from the “I moved away from Twitter, etc.”. I feel that it does me better to not follow daily news. I also stopped reading newspapers a while ago (though “Der Freitag” was an excellent subscription newspaper, which I enjoyed for a long time).

New Interests
Good bakeries are few and sparse in Berlin. This is in stark contrast to the south of Germany where there are typically a couple dozen good bakeries in a small town like Ulm — each with a vast selection of breads and some which still bake bread in-house. I miss this and that’s why I have started baking bread. Overall, I think I must have baked ~20 breads in the last months.

In the past I was reluctant to bake bread at home, due to the worse DIY bread I have been served in the past. This DIY bread was mostly bad because it was made in an oven which wasn’t capable of generating enough heat to have a real, “proper” crust. It is possible though, if you get yourself a dutch oven (which I have). It’s actually quite easy and astonishing how little ingredients are necessary to make a nice bread. You can go a long way with just flour, salt, water and yeast.


University Life
My university life is finished now. Whilst I had the most amazing time of my life during my B.Sc., I couldn’t follow that up in my M.Sc. and the last semesters were more frustrating than fulfilling. Nevertheless my academic career shed out two further publications this year: My master’s thesis has been properly published, it has a DOI now and is published by the University Ulm (publication page, pdf). Furthermore, another project was published: Circular Selection — I made its code freely available on GitHub (repository).

In the past I did a lot of freelance work besides university (some web development stuff, some software development and some media stuff) and worked in many different roles at university (mostly as a research assistant). This year I got my first proper, professional full day job though. It’s quite a different experience, but I enjoy that I now finally have a time where I can go home and don’t still have to do work. The same goes for weekends, this now really is my free time. At university this was very different and I think for my entire time there I never had any period where I had the feeling that there is nothing I must work on. There was always something to be done, handed in, read about, etc..

I wrote a separate blog post on that topic again.

A short story which really stuck with me was “Trolls Head” by Christopher Fielden, it is sadly not available online though.

Best Photo I shot
I really like the photos I took in India earlier in 2016. I am also very satisfied with some portraits I took of people close to me.

IT & tools
There is no certain “new shiny” tool that I discovered and use now all the time, but lots of small improvements. I am very comfortable with my digital home. I still use Arch Linux and a version of dwm which I modified in some ways which suit me. I still have a heavy focus on the shell and my main tools are tmux, git, vi, ksh, and mmh.

At work I regularly do devops on linux servers and recently out of fun set up my own virtual server to play around a bit. I have kept it and use it for some stuff now.

A theme which has resonated with me throughout this and the last year surrounds Artificial Intelligence, Singularity and the border of human consciousness/machine intelligence. The article “Why Digital Computers Can’t Have Consciousness” postulates an interesting perspective on why conscious machines may not be achievable with current technologies. Though I don’t agree with everything in the article, it provides an interesting perspective. This article provides an opposed point of view.

Outstanding Video/Trailer/Commercial
Valerie showed me Lillies of the Valley and told me about Pina Bausch. The video is really nice and shines some light on the excellence of this choreographer.

I think the Deus Ex — The Mechanical Apartheid trailer is done extremely well and paints an interesting vision of a not so far future. In terms of commercials I enjoyed the visual style and cyberpunkish vibe of the Yamaha – The Dark Side of Japan commercials. This reinforced my interest of visiting Tokyo in the near future.

I haven’t watched that many movies or series throughout the year. This is something that really changed in the last three years or so. I still occasionally go to art-house cinemas, but quite seldom. In late 2016 I finally got myself to watch the last few episodes of Dexter, a series that I liked a lot in the past. I was very disappointed by the ending though (as a lot of other people were).

Two series which I on the other hand enjoyed a lot just in the last two months were the clever reboot of Westworld and the reality-based Narcos. I also liked the BBC adaption of the War and Peace series (it’s six parts). The score of the series is outstanding.

Valerie got me interested in Woody Allen and I watched some of his movies with her. I like them actually, they don’t take themselves too serious and often show an idealistic world and depict themes surrounding love. “Vicky Cristina Barcelona” was my favorite so far, I enjoyed that movie a lot.

What stands out this year is White Buffalo, whom I discovered in Buenos Aires, and the electronic music group LORN. Both hit the right vibe at the right time and I listened to much of them.

Technologies I discovered
Stefan deserves credit for getting me hooked on the Aeropress and Chemex. Something I enjoy daily.

Honorable mentions
I discovered (by chance) that a visualization I produced is used for the title picture in a Wikipedia article. That was nice. Also some of my GitHub projects have gathered a number of stars (one even has a couple hundred); that’s also nice to see.

Finally set up a website/blog for Valerie: http://www.valerie-kast.de.

Got some older projects to work again. Among them is findsgut.de, a platform I created as a hobby project with some friends 2-3 years ago.

Set up a Unix diary: http://micha.elmueller.net/unix-diary. I haven’t announced this here properly, but I added it to the sidebar now.

Looking forward to 2017
What will 2017 hold? I don’t know, but hopefully more satisfaction.

My new year resolutions are:

  1. Buy maximum 5 clothing items.
    I already did that two years ago and found it quite easing to not have the option of buying a lot of stuff.
  2. Cook a new meal each week.
    This is also a repeater with a positive record.
  3. Learn more Spanish and don’t lose all the stuff learned in South America.
  4. Finish up some old, half-finished projects.
  5. Phone more with friends.
  6. Donate more.
  7. Make one publication.
  8. Get rid of more stuff, keep striving for minimalism.

About Me

I am a 29 year old techno-creative enthusiast who lives and works in Berlin. In a previous life I studied computer science (more specifically Media Informatics) at the Ulm University in Germany.

I care about exploring ideas and developing new things. I like creating great stuff that I am passionate about.
