ASUS ZenBook 3 ファーストインプレッション

前使ってたSony VAIO Pro 11が壊れた。

"Sony"は勘違いではなく、実際まだVAIOが分社化する前に買ったものだ。なのでかなりながらく使っていたと思う。すぐ壊れるという前評判と経験則をおおいに裏切って延長保証が切れるまでなんの問題もなく動き続けてくれた。買ってよかったと思う。

とはいうものの壊れてしまったので、別のものを買わなければいけないのだが、残念ながら今回はVAIOは選択肢に入らない。VAIO Pro 11に相当する後継製品がないからだ。なおS11はキーボードがNG。

色々と調べた限りでは国内で買える選択肢は少なそう。しょうがないので、ASUS ZenBook 3 UX390UAKを個人輸入でUS Amazonで買った。

Subject: [PATCH] send-pop optimisation part two: eliminate pop

Sending a method, then immediately throwing away its return value, is
one of the most frequent waste of time that ruby does.  Now that
callee methods can skip pushing objects onto the stack, why not caller
sites to also avoid popping them.

Subject: [PATCH] print N-gram of instructions that run

This is different from N-gram of generated iseq.  Rather it prints
the sequence that was actually executed.
