Neural Networks

Even if I do not have time, I simply had to write this article. As I said, there is a biological limit to how much you can actively work in a week. In addition to that, one can still do passive things like reading or watching Youtube videos. The algorithm has now suggested a very interesting video for me about neural networks:

The whole thing is related to a project, which I did not mention in my previous article because I did not pursue it. But only because of the time / benefit relation, the topic is extremely interesting.

At this point, I just have to write a status report about the items from my Todo List. I'm a bit active in the open source movement and have several projects underway where I have promised to contribute. Now, of course, this is a bit difficult if the work / company has been using up my creativity for so long completely. On the other hand, I have always delivered in my life what I promised. No idea if I can keep that up if you look at this:

At the moment, I am fighting with a total reconstruction of our shop, after the bankruptcy of our main supplier last autumn has blown up all other plans. This requires an tremendous effort to do everything necessary in the required time. In other words, 80 hours of work per week is noted as leisure time, most of the time I'm scratching at the biological limit, which is somewhere around 100 hours. More is less productive because you fall asleep in the middle of something. Now, however, I can well explore on myself how to be motivated for more than half a year for such a exertion - and that in turn depends very much on the Enneagram.

INTJ and creativity


Over the holidays, I finally get to work on my ToDo list regarding this blog. This list includes every topic I want to address, and creativity has been on it for a long time. So this is also an answer to INTJunicorn. Although I am not a professional artist, I put my nose into some art forms and at least got ridiculously underpaid Euros for it. And yes, the question is whether as a highly organized, "emotionless" INTJ can do anything with art at all is worth a look.

But we start at the very beginning. There are two artistic subjects at school here: art and music. Art just means painting with watercolors, and I was not so good at that. Although I took the ninth place in a children's painting competition and my shot at etching (bird's nest in the tree) was at least good enough to be hung public with the other best pictures in the class (and unfortunately never returned). In hindsight everything was rather modest, since my imagination could never quite keep up with my painting technique. I had already considered showing these art works here, but then the stereotypical INTJ perfectionism won again: we only go public with something if we know it's good. For the outsider, it may seem like we are awesome with everything we do, in fact, we only hide what questions that image.

Permanent Input

Sure, INTJ are not known as social contemporaries and Christmas is the time for social gathering. Fortunately, I have the gift of a strong sense of self-awareness and could recognize some amazing details this year. I have a little nephew who is turning two now. This one is - like most biennials - not to keep quiet in his chair, but runs around in the apartment, touches everything (especially everything that looks like a car) and woe, you take it away, then the crying begins. As a result, he is allowed to do it all. Sure, two-year-olds are in the middle of getting to know and interacting with their surroundings.

What struck me now is that I feel the same way, but in contrast I am not allowed to do that, it is expected socially that i just have to sit quietly in my chair and listen to the chatter of the adults. Evilly formulated. INTJs are not different in that respect from two-year-olds: we too need a permanent mental stimulus, and conversation about topics that are not interesting in our eyes simply does not count.

As an INTJ I do not belong to the personalities with a percieving function, unlike an INTP. Here, however, the model also reaches its limits if I am to classify my self-observation here. The functions of INTJ are Introverted Intuition, Extroverted Thinking, Introverted Feeling and Extroverted Sensing. This also makes sense so far, since the two extroverted functions represent my productivity outwardly well, both abstractly and tangibly. According to MBTI, percievers are personalities that have Introverted Feeling or Thinking as one of the first two functions, and are thus particularly responsive to environmental influences, unlike Ni or Si, which has to do with information processing. Of course, that's true in the first place, and what happens around me usually leaves me cold.

Oculus Rift

I built myself a PC some time ago to run Hauptwerk, especially the Rotterdam organ, which meant a very quiet case and cooler, an I7 4790K and 32GB RAM. When I stumbled over the Microsoft Flight Simulator, I also built in a decent graphics card (Geforce 1070 with 8GB). On the advertising pages of the graphics card driver was information about VR games, so in the aftermath I had an eye on it. More or less unplanned, I decided to buy an Oculus Rift in late November, together with The Climb.

Virtual Reality Experience

The first conclusion: VR is just cool. When I was in Trier for the Christmas shopping, I was really wondering why the customers in the media markets do not carry these things out on a pallet-wise - instead, it seems that the VR glasses have not yet reached the mass market. The Oculus Rift is already pretty mature and affordable with 449 €, a good monitor costs about the same amount. During the setup, I blocked myself first a few days because I did not find the HDMI output on the graphics card and thought it had four display ports. Only after the newly ordered HDMI on Displayport adapter did not work, I've read through the description again and found that behind the third same-looking plug of the graphics card actually hides a HDMI. The setup was pretty straightforward and the introduction is just cool: the touch controllers are presented as the virtual hands, they are exactly where your hands should be and do exactly what your hands do - grab, point ... and everything in 3D.

INTPMom - Nachtrag

There is an addendum to the article: "INTPMom": My mother is INFP and unfortunately can not speak English, so I have given her the article to read in the German translation. Her opinion was that this is terribly lonely and invented the very nice comparison that INTP / INTJ are lonely castles. Right. In that case, you can go one step further, that either INTx lives alone in the castle - which is not bad at all - or if you find a soul-related INTx, then it is just two, but just as lonely in relation to the world. I had to make it clear to her, that's just how it is, and we do not mind. Well, I would prefer the state of "lonely together" to "lonely alone" and have spun the comparison a little further: The problem is then that the lonely castles also hide and want to be untraceable. I seem to be an exception because I've been hired a barker for a long time (means online dating, blogs ...), unfortunately, but still no one finds me. On the other hand, looking for INTx in the dating portals is fruitless. That, however, is really not logical: Of course, online is pretty frustrating, but better that than nothing and the latter makes really sure that you will not be found. So far, nothing better has occurred to me with better chance of success. It does not work on the street anyway and I can not change my job every few months just to meet other people.

Typisierung: Hermione Granger

This article is a good example of the merciless INTJ objectivism. Actually, I wanted to prove here that Hermione Granger is an INTJ, despite different opinions in various forums. Then I read again volumes 6 and 7 and had to revise my opinion. What distinguishes an INTJ from many other types is that opinions are (almost) based solely on facts, and if the facts just do not support the opinion anymore, you have to change it, it is that easy.

So what personality type does Hermione Granger from Harry Potter have? There are essentially two opinions: INTJ and ISTJ, but INTP and ESFJ have also been mentioned. After skimming through the last two volumes, I first noticed that the books are almost exclusively about Harry, Ron and Hermione are really little more than sidekicks and do not have much text. What you can say: She is clearly introverted: she draws her power from within (there is this scene where she sits alone in a classroom with the little birds around her). Apart from Harry and Ron, she does not have any friends, and these only because they met each other on the very first ride on the Hogwarts Express.

True words ... from intpmom

I'm always rummaging through the web for interesting blogs - from and with INTx. So I came across The blogger is INTP and has given up her scientific career in favor of two children. Again, it is a good read in a congenial style.

Especially worth reading were these four articles:

Nobody let me help

This headline is not quite right, but right for the things that I would really like to improve, to contribute to. I now have quite a handful of repositories at GitHub and Sourceforge where my suggestions for improvement have simply been rejected. Why is that exactly? I have no idea. Either other people do not see the need for improvement, or they do not like the way I made the improvements or ...?

Actually, it is very prevalent in the software field, if not part of the principle, that several volunteers work together. In principle ... Let's take Mach3. This is a home-use CNC software, and a lot of hobbyists are using it to remodel their own machines (and it's not freeware). If you want to cut threads on the lathe

Mach3-cut thread M8

then you can not determine the machine code directly and the included tool was ... let's say very rudimentary.

Blöder Perfektionismus

I don't know if I it's possible that i have the worst possible combination of personality traits: The analytic-logical side of the INTJ combined with the perseverance of the perfectionist (Enneagram 1). Worst in the sense of: No one else is that freaky. Anyway, that's how it feels in these days. Example 1: This photo

My Prusa I3 Mk2

My Prusa I3 Mk2 with modifications, shot with three flashes

As with many other things that I do, this photo also has two purposes, which is simply more efficient: on the one hand the photo as such, on the other hand the pictured 3D printer. I wanted to discuss the latter for the same reason and I saw the potential for a good photo, then I wanted to make one. Click once with the phone would have taken 5 seconds. This photo about 4 hours.

INTJs - similiarities across borders

The discussion about the reliablility of MBTI is constantly flaming up again and again. An INTJ-Youtuber Youtube Channel: INTJ lost it completely (untypical for an INTJ), erased everything, and claims now that all this is nonsense. On the other hand, I had an experience that, on the contrary, is a very strong argument for people with the same MBTI type being very similar. I came across this blog: and although the blogger - Geomeun Goyangi - is a woman from a very different culture - somewhere in Asia - the content could easily be mine, even the writing style - with a penchant for side notes - is similar. This means nothing else than that the thought structures for a type are the same regardless of the environment.

Repair instead of new

From the series: you can fix almost anything. Since I am against wasting resources and the throwaway society I prefer repair, even if noone is doing it because it simply takes too long and is thus too expensive. The outdoor lights stopped shining, which was not very surprising given their new function as a underwater spotlight:

underwater spotlight ...

underwater spotlight ...

Every 'normal' buisinessman would've junked them and bought some new ones, but I'm not normal and quite frugal.
