smoke, twitter, Democrats

Brittney Cooper posted a question: is it a capitulation to the status quo by making any concessions to Democrats? All comes to the point that we vote in ways to reduce harm. that vote does not means a complete and total yes. Adam Davidson has something about similarity between smoke and tweet. Go read it. The gist is that big corporations figured out how to abuse our instincts. It may be tweets, smoke, sugar, fat, salts, or others. ...

Hope is what life is

In the dark time, to act is more important than to hope. Samantha Rose Hill once wrote that “for Hannah Arendt, hope is a dangerous barrier to courageous action. In dark times, the miracle that saves the world is to act.” Life is always about hope. Then in an interview, Saidiya Hartman said the follows about the advice of “Don’t despair.” Here is the excerpt: “What is joy? What is joy? I tend to describe joy as this experience of transformation or release from the constraint or costume of the individual or the subject into this other form. So, for me I think it’s about floating, it’s about being nothing and being everything at the same time; this sense of the self disappearing in the context of the vastness of the earth, the ocean, the sky, the land. That kind of joy is always about self-dissolution, escape. And my favourite colour? My garden in full bloom. I’m a gardener, so I love the colours in my garden and I love just playing with colours. I’ll show you my dahlias (shows image on phone), these are from my garden. Deep purples, deep burgundies towards black. The garden’s blackest flowers. And finally, I don’t know if I would have a question or advice, but probably the advice that I would give myself would be something like ‘don’t despair’. Don’t despair.” ...

四通桥彭载舟抗议之后,孤勇者一时风行,据说上海封城的时候就流行过。当听到陈奕迅的演唱之后,总觉得耳熟。搜了搜,原来英雄联盟之双城之战的英文名Arcane,这部从游戏改编而来的漫画我其实是看过的。 致那黑夜中的嗚咽與怒吼 誰說站在光裡的才算英雄 由此又想到鲁迅的一首诗: 万家墨面没蒿莱,敢有歌吟动地哀。 心事浩茫连广宇,于无声处听惊雷。

Reading Pachiko

Pachiko is not a story but a historical summary of Korean Japanese from 1910 to 1989. It reminds me of blacks in USA, Malays in Singapore, and all minority migrants in the Western countries. Darwin’s natural selection is never about the fitness but the changes and the adaptation. Man will never change but be forced to change. That is the natural selection in human history. States, institutions like schools, police, courts, and many others are just ideas. Men believe in ideas. ...

Loneliness

An excerpt from Deleuze on Godard. I can tell you how I think of Godard. He’s a man who works very hard, and it follows that he is completely alone. But this loneliness is not the common sort: it’s filled by a huge assortment of things. Not dreams, fantasies or projects, but actions, things and even people. It is a many-faceted, creative loneliness. It’s what lies behind Godard’s ability to operate powerfully on his own, but also as part of a team. He can deal on equal terms with anyone, with big organizations or the powers that be, with a cleaning lady, a manual worker or the insane. In the television programmes, Godard’s questions are always straight. They trouble us, the viewers, but not the people they are addressed to. He speaks to the insane in a way which is not that of a psychiatrist or that of a fellow madman or someone pretending to be one. He speaks with workers without being a a boss or another worker or an intellectual or a film director with actors. This is not because he can switch his manner to suit the occasion, because he is a skillful operator, but because his loneliness somehow opens him up to anyone and everything. In a way, it’s always a question of stammering. ...

interesting stuff

For the first time someone complained that I swam too fast 记得以前看过一篇文章说游得好自然就快。我不知道自己游得好不好,反正并不快,所以一直在慢的泳道。大学时学会游泳,以前常游。后来有些时间没有条件,也没有时间。最近这段时间我已经坚持游了有近十年,快慢不论,体力还是有的。 120-year-old singing bird It’s amazing like a real bird chirp. Horace Mann Die Gewohnheit ist ein Seil. Wir weben jeden Tag einen Faden, und schließlich können wir es nicht mehr zerreißen. The habit is a rope. We weave a thread every day, and finally we can’t tear it apart anymore. 如果文化也如绳索,一丝一缕不断编织,到头来坚韧如枷锁难以断开。 Theodor W Adorno Kunst ist Magie, befreit von der Lüge, Wahrheit zu sein. ...

Quine program

Definition of Quine A quine program, or quine, is a program that outputs its own source code when runs without taking any input. It is called self-replicating program. Quines are possible in any Turing-complete programming language, as direct consequence of Kleene’s rescursion theorem. Detour Quine’s paradox on self-reference. "Yields falsehood when preceded by its quotation" yields falsehood when preceded by its quotation. Another paradox: If the human brain were so simple that we could understand it, we would be so si mple that we couldn't. - Emerson M. Pugh Another amusing quote: ...
