Yukihiro Matsumoto quotes

I didn't work hard to make Ruby perfect for everyone, because you feel differently from me. No language can be perfect for everyone. I tried to make Ruby perfect for me, but maybe it's not perfect for you. The perfect language for Guido van Rossum is probably Python. (Yukihiro Matsumoto)
The orthogonal features, when combined, can explode into complexity.
Yukihiro Matsumoto
Computers are not very smart. They don't understand human language, so we have to tell them what to do in a language that both humans and computers can understand.
Yukihiro Matsumoto
You want to enjoy life, don't you? If you get your job done quickly and your job is fun, that's good isn't it? That's the purpose of life, partly. Your life is better.
Yukihiro Matsumoto
In our daily lives as programmers, we process text strings a lot. So I tried to work hard on text processing, namely the string class and regular expressions. Regular expressions are built into the language and are very tuned up for use.
Yukihiro Matsumoto
From the viewpoint of what you can do, therefore, languages do differ - but the differences are limited. For example, Python and Ruby provide almost the same power to the programmer.
Yukihiro Matsumoto
Often people, especially computer engineers, focus on the machines. They think, "By doing this, the machine will run faster. By doing this, the machine will run more effectively. By doing this, the machine will something something something." They are focusing on machines. But in fact we need to focus on humans, on how humans care about doing programming or operating the application of the machines. We are the masters. They are the slaves.
Yukihiro Matsumoto
Everyone has an individual background. Someone may come from Python, someone else may come from Perl, and they may be surprised by different aspects of the language. Then they come up to me and say, 'I was surprised by this feature of the language, so Ruby violates the principle of least surprise.' Wait. Wait. The principle of least surprise is not for you only. The principle of least surprise means principle of least my surprise. And it means the principle of least surprise after you learn Ruby very well. For example, I was a C++ programmer before I started designing Ruby. I programmed in C++ exclusively for two or three years. And after two years of C++ programming, it still surprises me.
Yukihiro Matsumoto
Because of the Turing completeness theory, everything one Turing-complete language can do can theoretically be done by another Turing-complete language, but at a different cost. You can do everything in assembler, but no one wants to program in assembler anymore.
Yukihiro Matsumoto
Actually, I didn't make the claim that Ruby follows the principle of least surprise. Someone felt the design of Ruby follows that philosophy, so they started saying that. I didn't bring that up, actually.
Yukihiro Matsumoto
People are different. People choose different criteria. But if there is a better way among many alternatives, I want to encourage that way by making it comfortable. So that's what I've tried to do. (Yukihiro Matsumoto)
Ruby inherited the Perl philosophy of having more than one way to do the same thing. I inherited that philosophy from Larry Wall, who is my hero actually. I want to make Ruby users free. I want to give them the freedom to choose.
Yukihiro Matsumoto
I believe consistency and orthogonality are tools of design, not the primary goal in design.
Yukihiro Matsumoto
Most of the tasks we do are for humans. For example, a tax calculation is counting numbers so the government can pull money out from my wallet, but government consists of humans.
Yukihiro Matsumoto
Imagine you are writing an email. You are in front of the computer. You are operating the computer, clicking a mouse and typing on a keyboard, but the message will be sent to a human over the internet. So you are working before the computer, but with a human behind the computer.
