R.I.P Dennis Ritchie

 Tin Dennis Ritchie mất đã được đăng nhiêu ngày trên mạng. Nhưng nay tớ vẫn viết 1 bài để tưởng nhớ người đã tạo ra ngôn ngữ C đồng thời là developer chính phát triển UNIX

Với người dùng máy tính bình thường, có lẽ họ chẳng biết ông là ai. Nhưng với những lập trình viên, hẳn ai cũng biết vai trò của ông lớn chừng nào. Ngay cả Bill Gates, Steve Jobs... cũng là những người khổng lồ đứng trên vai người khổng lồ vĩ đại này.

Rest In Peace!

"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."

"UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity"

Một đoạn code tưởng nhớ ông:
int main(void)
{
time_t thetime = time(NULL);
struct tm *loctime = localtime(&thetime);

struct ritchie *dennis;
while (1) {
if (loctime->tm_year + 1900 == 1941) {
dennis = (ritchie*) malloc(sizeof(struct ritchie));
} else if (loctime->tm_year + 1900 > 1941
&& loctime->tm_year + 1900 < 2011) {
change_the_world_of_computers();
} else if (loctime->tm_year + 1900 == 2011) {
free(dennis);
break;
}
}
return 0;

Ritchie sống bình lặng, số quote nhặt được trên mạng rất ít:

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

Any editing, software work, and mail is done in this exported Plan 9.
Dennis Ritchie

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

At the same time, much of it seems to have to do with recreating things we or others had already done; it seems rather derivative intellectually; is there a dearth of really new ideas?
Dennis Ritchie

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

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

C++ and Java, say, are presumably growing faster than plain C, but I bet C will still be around.
Dennis Ritchie

For infrastructure technology, C will be hard to displace.
Dennis Ritchie

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

I fix things now and then, more often tweak HTML and make scripts to do things.
Dennis Ritchie

I'm just an observer of Java, and where Microsoft wants to go with C# is too early to tell.
Dennis Ritchie

I'm not a person who particularly had heros when growing up.
Dennis Ritchie

I've done a reasonable amount of travelling, which I enjoyed, but not for too long at a time.
Dennis Ritchie

Obviously, the person who had most influence on my career was Ken Thompson.
Dennis Ritchie

Over the past several years, I've been more in a managerial role.
Dennis Ritchie

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

The visible things that have come from the group have been the Plan 9 system and Inferno, but I hasten to say that the ideas and the work have come from colleagues.
Dennis Ritchie

UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity.
Dennis Ritchie

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
