1
So I wrote to Yarna, I said, Yarna, what does clean code mean to you?
2
And he said, and this is very typical of Yarna Strewstrup, he said, I like my code to be elegant and efficient.
3
And then he said this, clean code does one thing well.
4
One thing well.
5
Now this one thing idea has been around in software for 40 years or more.
6
People are always writing about how a function should do one thing and one thing well.
7
It's a very, very old idea.
8
And Strustrip echoes it here.
9
Grady Booch, the chief scientist at Rational.
10
He wrote a book in 1988 called Object-Oriented Software Design with Applications.
11
Anybody read that book?
12
1980s, late 80s?
13
Do we have anybody who was born then?
14
Yeah, okay, good.
15
All right, so that's fine.
16
Fascinating book, very early book on object-oriented design.
17
Grady Butch is also the first person, I believe, to have the title chief scientist.
18
I think he invented that.
19
And Rational said, yeah, you can be the chief scientist, that's fine.
20
And ever since then, everybody's wanted to be a chief scientist at some company somewhere.
21
So I asked Grady, you know, Grady, what's clean code?
22
He said, clean code is simple and direct, fine.
23
And then he said this, clean code reads like well written prose.
24
Have you ever read code that read like well-written prose?
25
And let's go to Michael Feathers.
26
Michael Feathers.
27
I wrote to Michael, I said, hey Michael, what's clean code?
28
And he said, clean code always looks like it was written by someone who cares.
29
What a lovely statement.
30
That's a good attitude right there.
31
Clean code always looks like it was written by someone who cares.
32
When's the last time you read a module
33
and your thought as you were reading that module was the author cared about me.
34
The author cared about everybody else who was going to be reading that code.
35
When's the last time you had that experience, the author of this code cared about me.
36
Very interesting.
37
And by the way, it brings up a fascinating point.
38
What's your job?
39
You may think that your job is to get code to work.
40
That's not your job.
41
That's only half of your job, and it's the least important half of your job.
42
The more important part of your job is that you must write code that other people can maintain,
43
can use, can make work.
44
If you hand me code that works perfectly, perfectly, but I can't understand it, then as soon as the requirements change, that code is useless.
45
On the other hand, if you give me code that does not work, but I can understand it, I can make it work.
46
It is much more important
47
that your peers be able to understand the code you write than that the computer can understand the code that you wrote.
48
It is more important to communicate with your peers using a programming language than it is to communicate with the computer.
49
Because if you do that well, somebody will make it work.
50
The last one.
51
Ward Cunningham.
52
Who knows who Ward Cunningham is?
53
Somebody heard the name?
54
You know who that is.
55
A few of you do.
56
You'll know who he is as soon as I tell you.
57
He's the guy who invented the wiki.
58
Who's used a wiki?
59
Everybody puts their hand up.
60
Okay, good.
61
Okay, Ward Cunningham is the guy who invented the wiki.
62
He invented the wiki out of 19 lines of pearl in 1990 something or other.
63
Put it up on the website.
64
By the way, that very first wiki is still alive.
65
You can get to it if you want to.
66
The URL is c2.com.
67
The letter C and the digit 2.com.
68
That is the very first wiki ever.
69
It's still there.
70
And by the way, it's full of fascinating stuff.
71
You'll see all kinds of design pattern stuff and extreme programming stuff
72
and agile stuff because it was there at the beginning
73
and i asked ward ward what's clean code and he said this
74
you know you're working on clean code when each routine you read turns out to be pretty much what you expected
75
when's the last time you read code
76
and as you're reading it it was pretty much what you expected you're reading along
77
and you're going yeah yes yep yep yep yes mm-hmm yep yep yep when's the last time you had that experience
78
what he's saying is no wtfs per minute zero clean code
79
is no surprises no wtfs everything is pretty much what you expected.
80
That's good clean code.

Grammatik in diesem Video
Die Strukturen, die der Sprecher am häufigsten verwendet, mit den genauen Worten aus dem Video:

Aussprache, auf die du achten solltest
Der Sprecher verwendet 7 Kurzformen und abgeschwächte Formen, zum Beispiel you're, you'll, can't. Sprich sie in der kurzen Form, so wie du sie hörst.
Laute, die Deutschsprachigen schwerfallen:
- /w/ — mit runden Lippen, nicht wie das deutsche „w“ (/v/): wiki /ˈwɪki/, ward /wɔɹd/, requirement /ɹɪˈkwaɪɹmənt/
- Stimmhafter Auslaut — /b/, /d/, /g/, /z/, /v/ am Wortende nicht verhärten: ward /wɔɹd/, prose /ˈpɹoʊz/
- /æ/ — offener als „ä“: fascinate /ˈfæsɪneɪt/, agile /ˈæd͡ʒ.aɪl/
So übst du mit diesem Video
- Höre dir das ganze Video einmal an, ohne zu sprechen, und notiere die Wörter, die du nicht kennst.
- Sprich Satz für Satz in normaler Geschwindigkeit nach und wiederhole jeden, bis dein Rhythmus zum Sprecher passt.
- Nimm dich auf und vergleiche mit dem Original; achte dabei auf Wörter wie wiki, ward, scientist.
Was ist die Shadowing-Technik?
Shadowing ist eine wissenschaftlich fundierte Sprachlerntechnik, die ursprünglich für die professionelle Dolmetscherausbildung entwickelt und durch den Polyglotten Dr. Alexander Arguelles populär gemacht wurde. Die Methode ist einfach aber wirkungsvoll: Du hörst englisches Audio von Muttersprachlern und wiederholst es sofort laut — wie ein Schatten, der dem Sprecher mit nur 1–2 Sekunden Verzögerung folgt. Anders als passives Hören oder Grammatikübungen zwingt Shadowing dein Gehirn und deine Mundmuskulatur, gleichzeitig echte Sprachmuster zu verarbeiten und zu reproduzieren. Studien zeigen, dass es Aussprachegenauigkeit, Intonation, Rhythmus, verbundene Sprache, Hörverständnis und Sprechflüssigkeit signifikant verbessert — was es zu einer der effektivsten Methoden für die IELTS Speaking-Vorbereitung und reale englische Kommunikation macht.
