Piano by Edgar Kunz I held him together as long as I could, she says. He stopped working, stopped coming upstairs. He was like tissue paper coming apart in water. Like smoke in my hands. It had nothing to do with you, baby. You left when you had to. I met a woman once who worked on pianos. Said it was a hard job. The tools, the leverage. The required ear. I love it, she said, but it’s brutal. ...

For someone my age who was in the civil rights movement, and in other struggles of the 1960s, I’ve seen miracles happen. I’ve seen ordinary people do the most heroic things. When you’ve had the privilege of knowing so many great fighters and resisters, you can’t lay down the sword, even if things seem objectively hopeless. I’ve always been influenced by the poems Brecht wrote in the late 30s, during the Second World War, after everything had been incinerated, all the dreams and values of an entire generation destroyed, and Brecht said, well, it’s a new dark ages … how do people resist in the dark ages? ...

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. ...

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.” ...

Here is SD example code from esp-idf. Here is one header file for esp32 fatfs. use 4-line SD mode, consider the 10K pullup resistors on data lines code page: FF_CODE_PAGE : CONFIG_FATFS_CODEPAGE 437 US What is the biggest micro SD card for esp32 fatfs? 16GB? FAT = file allocation table FAT32 individual files on a FAT32 drive cannot exceed 4GB size limit. FAT32 partition must be less than 8TB. exFAT file system: extended file allocation table. ...

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。

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. ...

To run esp privilege separation, have to update esp-idf to v4.4.2. This kernel-user application was announced several months ago. Just notice it today. It adds to another new option for WM. $ cd $IDF_PATH $ git fetch $ git checkout v4.4.2 $ git submodule update --init --recursive $ ./install.sh $ . ./export.sh After the update, have to patch esp-idf for esp-privilege-separation. $ cd $IDF_PATH $ git apply -v ../esp-privilege-separation/idf-patches/privilege-separation_support_v4.4.2.patch Then run the blink example inside esp-privilege-separation repo. $ idf.py set-target esp32c3 $ idf.py menuconfig $ idf.py build $ idf.py -p /dev/tty.SLAB_USBtoUART flash monitor Here is the log. ...
