Proč je Jiu Jitsu ideálním sportem pro IT profesionály

Brazilské jiu jitsu, zkratkou BJJ, je jedním z nejkomplexnějších bojových umění všech dob. Zahrnuje nepřeberné množství technik a jejich kombinací, přičemž se tyto techniky neustále vyvíjejí a zdokonalují. Mnoho technik je zaměřeno na překonání silnějšího a většího oponenta. BJJ se primárně zaměřuje na boj na zemi, a obsahuje judo techniky a wrestlingové takedown techniky (je samozřejmě důležité dostat oponenta na zem). Poté, co se oponent dostává na zem, ztrácí téměř všechny silové páky, které by jinak mohl využít. Takto lze překonat i oponenta třeba o 40 kg těžšího (zde je video, kde se žena ubrání násilníkovi na ulici pomocí BJJ). V moderním MMA tvoří BJJ velkou část dovedností nutných pro šanci uspět, obzvlášť když se boj přesune na zem. V tomto článku se dozvíte, proč je právě BJJ tak skvělé fitness pro IT profesionály, a to jak muže, tak ženy.

Story analysis of my top 3 favorite dystopian games

Okay, I am gonna tell you about my top 3 favorite games. All of them share similar characteristics, like the hero fighting against tyranny or nihilism. All of them are existentialist, dystopian and partly post-apocalyptic. I am going to analyze the story, setting and philosophy behind these games. Let’s do it!

NFTs, DeFi, chytré kontrakty a jaká je jejich budoucnost

Hlavními trendy ve světě kryptoměn jsou teď decentralizované finance, DeFi, a non-fungible tokens, NFT. Obě technologie mohou využívat tzv. chytré kontrakty. V tomto článku se podíváme na všechny 3 zmíněné pojmy, popíšeme si, co znamenají pro vývoj kryptoměn a kde se používají, a také zvážíme jejich výhody a nevýhody. Všechny 3 technologie se točí hlavně okolo Etherea, platformy, na které dnes stojí hodně altcoinů. Doporučuji přečíst si také moje starší články o tom, jak funguje blockchain, a dva díly (I., II.) o alternativních kryptoměnách.

How could Hitler influence whole nations to such an extent?

One of the “rehearsing photos” that Hitler wanted to be destroyed First, we will take a look at the political circumstances of Hitler‘s time that made his rise to power possible. Then we will assess the crucial events from his personal history and his psychological profile. And finally in chapter 7, we will analyze how a schizophrenic psychopath like him could influence whole nations.

1. What were the primary political and economic issues of his time?

Put yourself in the shoes of an average German in 1921. Your country just lost the Great War (WW1), you have to pay reparations to certain countries (roughly equivalent to $442 billion in 2021) and your military is severely restricted. Germany is forced to accept the sole responsibility for all the loss and damage of the war. Your national pride is shattered. You feel humiliated on the international stage. Then in 1929, the Great Depression strikes. The German economy begins to collapse. You cannot feed your family. Everyone around you is suffering. Then comes Adolf Hitler, the leader of the NSDAP party, and promises to restore national pride, take back the land lost in the war, and create more jobs. He has an enchanting charisma and it seems like he can vocalize every feeling of the crowd. He says everything the people want to hear — and then he does exactly what he promises. Everybody loves what he is saying. You believe this visionary leader will take you to a better future.

2. What were the crucial events of his childhood?

4 out of 5 of Hitler’s siblings died, which left a sense of him being exceptional in his mind. At the age of six, his father, Alois Hitler, retired on a pension from the Austrian civil service. He was an alcoholic and a brute and he often beat him. Little Adolf did well in the monastery school and considered becoming a priest. He was always bossy and even when playing with other children, he told them what to do. He is quick to anger and spoiled by his mother, Klara. His father was 22 years older than his mother. The whole family rented a cheap flat, but the mother kept everything shiny clean, as would later note the family’s doctor Eduard Bloch. Hitler’s obsession with cleanliness was fed since the beginning. At the age of 9, he discovered his hidden talent for drawing, especially buildings. He wanted to go to a classical school, but his father insisted on a technical secondary school. Hitler was deeply affected by the death of his younger brother Edmund, who died in 1900 from measles. Hitler changed from a confident, outgoing, conscientious student to a morose and detached boy.

3. Of his adolescence?

Hitler did very poorly in his first year of technical school and became very detached. There were many arguments with his father about his career choice. In Mein Kampf he states that he intentionally did poorly in school, hoping that once his father saw “what little progress I was making at the technical school he would let me devote myself to my dream”. Young Adolf found the idea of spending his life in an office job horrible, whereas his father saw the idea of him becoming an artist ridiculous. In high school, Hitler became interested in history and the idea of Pan-Germanism (unifying all the German-speaking people). His father died in January of 1903, ending their constant battles and allowing him to pursue his dream of becoming an artist. In 1906 he met a new friend, August Kubíček (Kubiczek), who had Czech parents. They shared a passion for the operas of Richard Wagner and became best friends and later roommates in Vienna. Hitler was fascinated with the mythological content of the operas, later using some of the themes in his ideology. Hitler was very close to his mother, so when she developed breast cancer, he didn’t cope very well. The doctor taking care of her was Czech Jew Eduard Bloch. After the war he shared his very interesting notes on the Hitler family:

“While Hitler was not a mother’s boy in the usual sense, I never witnessed a closer attachment. Their love had been mutual. Klara Hitler adored her son. She allowed him his own way whenever possible. For example, she admired his watercolor paintings and drawings and supported his artistic ambitions in opposition to his father at what cost to herself one may guess.”

Everything you do leaves a debt.

The basic law of the Universe is that of karma. Everything you do leaves a debt, be it good or bad. I use this philosophy for my everyday life. I know that when I will partake in hedonistic pleasures, it will incur a debt, I will have to pay for later. So, when I have a day that is full of easy things, then I know the second day will be full of difficult things. Thus I try to do very difficult things, so I can have an easy time later. The same goes for any kind of project. Be it your college project or a work project. When I go for the easy way out, and I make some short-sighted decision, it ALWAYS comes back, sooner or later, and kicks me in the butt. I can’t say how many times I used a “hacky” solution in a programming project, only for it to bring bugs or other implementation difficulties later on. Thus, I now I try to go for long-term decisions, that are often hard to make and implement but are the only right thing to do, compared to short-term solutions that will need a rework later. This concept even has a name in programming - it’s called “technical debt”. I realized the same thing about my college years. I used to do a lot of college projects at the last minute, and often create them so it worked so-so. I used to study for exams in the last 2 days and have cram sessions, often on some kind of a stimulant. Now, years later, I am not so confident in my knowledge, even though I have a master’s degree on the subject. Now I wish I paid more ATTENTION in my college years and put a deeper effort into my projects. But I was young and I had other things on my mind. I read somewhere that the “opposite of love is not hate, but indifference”. Or one could also say “lack of attention”. Paying attention is really what I feel is the most important thing. I regret not paying attention more. It’s the most valuable thing we have.

For every action, there is an equal and opposite reaction.

This 3rd Newton’s law could also be described in one word: enantiodromia. It’s a psychological term introduced by Swiss psychiatrist Carl G. Jung, the founder of analytical psychology

Enantiodromia is the emergence of the unconscious opposite in the course of time. This characteristic phenomenon practically always occurs when an extreme, one-sided tendency dominates conscious life; in time an equally powerful counterposition is built up which first inhibits the conscious performance and subsequently breaks through the conscious control.”
