    I Scraped Brother USA Website To Figure Out Which Sewing Machine Has One Function (Thread Cutter Button) That I Want

    Brother’s website for sewing machines is frustratingly limited – no proper catalog and terrible filters. When I wanted to check which models had a specific function, their filter only offered two options (knee lifter and built-in quilting stitches). Not helpful at all.

    Taiwan MRT Systems Arrival Time Estimation Indicator (Taipei MRT is the worst of the worst)

  • 我從來沒有理解區分文組與理組的原因

    可能因為我沒有被分過一二三四類組，所以無法理解區分文組跟理組的原因以及好處。把人貼上理組的標籤後，好像就能正大光明的鄙視其他人，覺得其他人不夠理性、不夠數學與不具有可預測性，覺得沒有辦法寫成定理的東西都是胡扯。
