秋月で買い物なんて高校生以来な気がする

I’d like to try making a picture in the style of 黃文勇. I saw his work at his solo exhibition in Kaohsiung last year (相無所相) and really liked it.

学生にお肉を食べさせたり、研究会で先生方にアイスをねじ込んだり、多分僕はそう言う類のハラスメント気質があるのだと思う

Attached an ADS-B receiver to a Raspberry Pi Zero W for Flightradar24. I still need to update the OS, though...

I feel more relaxed working on weekends than on weekdays, and late at night rather than during the day...
