UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.
Dennis Ritchie
UNIX is essentially an uncomplicated operating system, but one must be a virtuoso to comprehend the straightforwardness.
2.
The only way to learn a new programming language is by writing programs in it.
Dennis Ritchie
3.
Unix has retarded OS research by 10 years and linux has retarded it by 20.
Dennis Ritchie
4.
C was already implemented on several quite different machines and OSs, Unix was already being distributed on the PDP-11, but the portability of the whole system was new
Dennis Ritchie
5.
C is quirky, flawed, and an enormous success.
Dennis Ritchie
6.
C++ and Java, say, are presumably growing faster than plain C, but I bet C will still be around.
Dennis Ritchie
7.
For infrastructure technology, C will be hard to displace.
Dennis Ritchie
8.
A language that doesn't have everything is actually easier to program in than some that do
Dennis Ritchie
9.
... with proper design, the features come cheaply. This approach is arduous, but continues to succeed.
Dennis Ritchie
10.
I'm not a person who particularly had heros when growing up.
Dennis Ritchie
11.
Pretty much everything on the web uses those two things: C and UNIX.
Dennis Ritchie
12.
I can't recall any difficulty in making the C language definition completely open - any discussion on the matter tended to mention languages whose inventors tried to keep tight control, and consequent ill fate
Dennis Ritchie
13.
I'm just an observer of Java, and where Microsoft wants to go with C# is too early to tell.
Dennis Ritchie
14.
The number of UNIX installations has grown to 10, with more expected.
Dennis Ritchie
15.
Sometimes when you fill a vacuum, it still sucks.
Dennis Ritchie
16.
I'm still uncertain about the language declaration syntax.
Dennis Ritchie
17.
At least for the people who send me mail about a new language that they're designing, the general advice is: do it to learn about how to write a compiler
Dennis Ritchie
18.
A program designed for inputs from people is usually stressed beyond breaking point by computer-generated inputs.
Dennis Ritchie
19.
UNIX is simple and coherent, but it takes a genius (or at any rate, a programmer) to understand and appreciate its simplicity.
Dennis Ritchie
20.
The kind of programming that C provides will probably remain similar absolutely or slowly decline in usage, but relatively, JavaScript or its variants, or XML, will continue to become more central.
Dennis Ritchie
21.
Some consider UNIX to be the second most important invention to come out of AT&T Bell Labs after the transistor.
Dennis Ritchie
22.
From an operating system research point of view, Unix is if not dead certainly old stuff, and it's clear that people should be looking beyond it.
Dennis Ritchie
23.
Obviously, the person who had most influence on my career was Ken Thompson.
Dennis Ritchie
24.
Obviously, the person who had most influence on my career was Ken Thompson. Unix was basically his, likewise C's predecessor, likewise much of the basis of Plan 9 (though Rob Pike was the real force in getting it together). And in the meantime Ken created the first computer chess master and pretty much rewrote the book on chess endgames. He is quite a phenomenon.
Dennis Ritchie
25.
I listen to mostly-classical music, but mostly by radio - I'm not an audiophile.
Dennis Ritchie
26.
I've done a reasonable amount of travelling, which I enjoyed, but not for too long at a time.
Dennis Ritchie
27.
When I read commentary about suggestions for where C should go, I often think back and give thanks that it wasn't developed under the advice of a worldwide crowd.
Dennis Ritchie
28.
C is peculiar in a lot of ways, but it, like many other successful things, has a certain unity of approach that stems from development in a small group.
Dennis Ritchie
29.
Steve Jobs has said that Xwindows is brain-damamged and will disappear in two years. He got it half-right.
Dennis Ritchie
30.
I fix things now and then, more often tweak HTML and make scripts to do things.
Dennis Ritchie
31.
Any editing, software work, and mail is done in this exported Plan 9
Dennis Ritchie
32.
Twenty percent of all input forms filled out by people contain bad data.
Dennis Ritchie
33.
It seems certain that much of the success of Unix follows from the readability, modifiability, and portability of its software.
Dennis Ritchie
34.
One of the obvious things that went wrong with Multics as a commercial success was just that it was sort of over-engineered in a sense. There was just too much in it.
Dennis Ritchie
35.
Oh, I've seen copies [of Linux Journal] around the terminal room at The
Labs.
Dennis Ritchie
36.
A new release of Plan 9 happened in June, and at about the same time a new release of the Inferno system, which began here, was announced by Vita Nuova.
Dennis Ritchie
37.
The notion of a record is an obsolete remnant of the days of the 80-column card.
Dennis Ritchie
38.
My work was fairly theoretical. It was in recursive function theory. And in particular, hierarchies of functions in terms of computational complexity. I got involved in real computers and programming mainly by being - well, I was interested even as I came to graduate school.
Dennis Ritchie
39.
It's true that compared with the scene when Unix started, today the ecological niches are fairly full, and fresh new OS ideas are harder to come by, or at least to propagate.
Dennis Ritchie
40.
I've done a reasonable amount of travelling, which I enjoyed, but not for too long at a time. I'm a home-body and get fatigued by it fairly soon, but enjoy thinking back on experiences when I've returned and then often wish I'd arranged a longer stay in the somewhat exotic place.
Dennis Ritchie
41.
C is declining somewhat in usage compared to C++, and maybe Java, but perhaps even more compared to higher-level scripting languages. It's still fairly strong for the basic system-type things.
Dennis Ritchie
42.
The True-GNU philosophy is more extreme than I care for, but it certainly laid a foundation for the current scene, as well as providing real software.
Dennis Ritchie
43.
For books, I don't read much fiction, but like travel essays and good pop-science.
