世界文化展


不是指Epcot Center那種規模的,而是家中小朋友所讀小學二年班的功課,上一次做的是和我家淵源甚深的馬來西亞;今次做的則是關係也不淺的意大利,因為常吃薄餅及意粉之故!看看其他小朋友的展品,其實也頗有趣:
1)越拙劣的越顯得屬小朋友自己手筆;有一個做了立體可動的吊車放在版上,很難相信父母沒有幫大忙。
2)小朋友介紹該國知名人士,政治人物固然正路,但也有一些介紹流行偶像。最搞笑那個介紹美國知名人士三位:Taylor Swift, Selena Gomez及Justin Bieber,並註明Bieber雖本是加拿大人,但現居美國。還有一位日本知名人士只得圖不見名字,可能我孤陋寡聞,在我心目中的日本名人是小澤......征爾(名指揮家)

Splitting a stereo MP3

This is not something one needs to do often but I'm still surprised not many tools and forum posts are about this operation. I could have imported the file into a recording software which would manage the left and right channels as two tracks and pick one to export. However, I found a better solution: the open source software SoX (Sound Exchange) thanks to this post which contains the command to do so.
