Ken Thompson Quotes

When the three of us [Thompson, Rob Pike, and Robert Griesemer] got started, it was pure research. The three of us got together and decided that we hated C++. [laughter] ... [Returning to Go,] we started off with the idea that all three of us had to be talked into every feature in the language, so there was no extraneous garbage put into the language for any reason.

Ken Thompson was once asked what he would do differently if he were redesigning the UNIX system. His reply: "I'd spell creat with an e."

If you want to go somewhere, goto is the best way to get there.

I think the major good idea in Unix was its clean and simple interface: open, close, read, and write.

I would try out the [C++] language [at AT&T] as it was being developed and make comments on it. It was part of the work atmosphere there. And you'd write something and then the next day it wouldn't work because the language changed. It was very unstable for a very long period of time. At some point, I said, no, no more. In an interview I said exactly that, that I didn't use it because it wouldn't stay still for two days in a row. When Stroustrup read the interview he came screaming into my room about how I was undermining him and what I said mattered and I said it was a bad language.

I view Linux as something that's not Microsoft — a backlash against Microsoft, no more and no less. I don't think it will be very successful in the long run. I've looked at the source and there are pieces that are good and pieces that are not. A whole bunch of random people have contributed to this source, and the quality varies drastically. My experience and some of my friends' experience is that Linux is quite unreliable. Microsoft is really unreliable but Linux is worse. In a non-PC environment, it just won't hold up. If you're using it on a single box, that's one thing. But if you want to use Linux in firewalls, gateways, embedded systems, and so on, it has a long way to go.

There's going to be no serious problem after this.

The press, television, and movies make heroes of vandals by calling them whiz kids. ... There is obviously a cultural gap. The act of breaking into a computer system has to have the same social stigma as breaking into a neighbor's house. It should not matter that the neighbor's door is unlocked.

I think the open software movement (and Linux in particular) is laudable.

Anything new will have to come along with the type of revolution that came along with Unix. Nothing was going to topple IBM until something came along that made them irrelevant. I'm sure they have the mainframe market locked up, but that's just irrelevant. And the same thing with Microsoft: until something comes along that makes them irrelevant, the entry fee is too difficult and they won't be displaced.

I've seen [visual] editors like that, but I don't feel a need for them. I don't want to see the state of the file when I'm editing.

We have persistent objects, they're called files.

Hi, this is Ken. What's the root password?

'Gigabit' seems to mean 600 megabits. It's a VAX gigabit.

I used to [look at the Linux source code], for Plan 9. They were always ahead of us—they just had massively more resources to deal with hardware. So when we'd run across a piece of hardware, I'd look at the Linux drivers for it and write Plan 9 drivers for it. Now I have no reason to look at it. I run Linux. And I occasionally look at code, but rarely, so I can't really tell whether the quality has gotten better or not [since 1999]. But certainly the reliability has gotten better.
