シャドーイング練習: Linus Torvalds Explains What Makes Linux So Fast - 動画で英語スピーキングを学ぶ

Linus, do you follow any development of any new programming languages?

Do you see any language except C which is suitable for development of operating system?

So I have to say, I'm kind of old -fashioned and I'm really interested.

The reason I got into Linux or operating systems in the first place was I really love hardware.

I love tinkering with hardware.

Not in the sense that I'm a hardware person and giving me a soldering iron is a bad idea.

But I like interacting with hardware from a software perspective.

And I have yet to see a language that comes even close to C in that respect.

It's not just that C, you can use C to generate good code for hardware, it's that if you think like a computer,

writing C actually makes sense.

I mean, and I think the reason it works that way is the people who designed C

designed it at a time when you,

I mean, when compilers had to be simple and the language had to be kind of geared towards what the output was.

So when I read C, I know what the assembly language will look like, and that is That's something I care about.

I don't do a lot of programming myself anymore.

I'm a technical lead person.

I merge other people's code.

But if you go and look in the Linux Git history and look at what I do, the last few months, the kind of code I've changed,

I've made sure our file path lookup

takes as few cache misses as possible and all

that code is C

but in order to really be able to it's optimized at

the level where I worry about single instructions kind of thing and

especially single cache misses and I love doing that

because that's it's completely I mean to some degree people say you should not micro optimize

but if what you love is micro optimization that's what you should do

and we made sure our algorithms are good before we started the micro -optimization,

so I'm very proud of the fact that we look up path names way faster than anybody else, I guarantee it, right?

And we can do it in parallel on a thousand CPU machine with no contention.

I mean, that is something that has happened in the last 18 months, and that is impressive.

I mean, you don't know how impressive it is Until you've worked with that code for, I mean, I thought we'd never get there, but we're there now.

So that's the kind of thing that really.

シャドーイングとは？英語上達に効果的な理由

シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
