The best part of the 20 years of Git celebration interview with Linus Torvalds was this bit about his choice of text editor. Which is MicroEMACS from 40 years ago, not used by anyone else today.

Instead of the endless rush to adopt whatever is the hyped tech of the day, you could choose to be more like Linus. Make your own choices based on what you really need.

If it worked for the guy who created and , why couldn't it work for you?

Use whatever works for you 
Linus Torvalds on his choice of text editor

Part of it is probably, I’ve been doing it so long that I can only do things in certain ways. I’m still using the same editor that I used when I was in college because my fingers have learned one thing and there’s no going back. And I know the editor is crap and I maintain it because it’s a dead project that nobody else uses.

So, I have a source tree and I compile my own version every time I install a new machine and I would suggest nobody ever use that editor but I can’t. I’ve tried multiple times finding an editor that is more modern and does fancy things like colorize my source code and do things like that. And every time I try it, I’m like, “Yeah, these hands are too old for this.” So I really hope there’s no project that comes along that makes me go, “I have to do this.”

[1]에서 문자열을 다룰 때 StrictTextBuilder의 성능을 비교하는 예제에서 Builder의 성능이 더 좋다고 설명한다. 그런데 내 PC에서 같은 코드를 실행했는데 결과가 반대로 나왔다. 이상해서 문자열 길이를 늘렸더니 책에서 말한대로 나왔다.

樂天股東優待:手機通話+上網30GB/月,全年免費。

樂天Mobile 從開辦以來一直赤字,但三木谷社長對Mobile 事業執念很深撐到現在總算稍有起色,而樂天集團有好幾個事業部也都獲利成長。趁這波跌深一張不到8萬圓耶。
