Shadowing Practice: Linus Torvalds Explains What Makes Linux So Fast - Learn English Speaking with Video

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.

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
