I want to learn how to write a compiler. Can someone help with the path, what
i need to be able to write a compiler. Any tutorial links?
And can someone help me with becoming a system programmer. What i need
and some tutorial links?
thnx.

>I want to learn how to write a compiler.
Okay, you need to know the language that the compiler processes inside and out, as well as assembly for all of the machines that the compiler will be run on (assuming you're compiling to machine code, it's easiest to output assembly and then assemble it into machine code). You need to figure out the grammar for the language, then design a parsing scheme. Naturally, any decent compiler will also have extensive error checking abilities so that it can produce useful diagnostic messages. Those tasks should give you a start.

>Any tutorial links?
Not off the top of my head, but you might consider picking up the dragon book as well as something more modern for a fairly thorough introduction.

>And can someone help me with becoming a system programmer.
What system? Systems programming is a very broad category that includes operating systems, networking, and databases. We implement the tools that applications programmers use to build and run applications. So what exactly do you want to do?

Thanks for the tip on "something more modern"

yeah what i want is the operating systems.
and also some free links to get the compiler tutorials from?

>yeah what i want is the operating systems.
Okay, do you want to write operating systems or maintain them? Are you more interested in working on the bare metal kernel or the system control operations that are delegated away from the kernel? Do you want to work with Windows based systems or POSIX based systems? Have you considered mainframes and embedded development?

>and also some free links to get the compiler tutorials from?
...What part of "not off the top of my head" is difficult for you? If I knew of any good tutorials I would mention them, but I have yet to see a systems or compiler programming tutorial that's worth a damn. Look at the books I suggested. For systems programming, there are plenty of books out there, but Richard Stevens' books are an excellent first step for UNIX systems programming, and the various "we can write a kernel!" books focused on Linux are informative. MSDN is a good reference for Windows systems programming, but you're not likely to find any material on the kernel or other back end stuff unless you make their OS development team. ;)

I'm only new here, but it seems that a lot of the posts in the forum are from people who say things like:

"I want to learn how to do ray tracing in cobol on a palm pilot; I don't know anything about programming yet, and clearly I'm not able to use a search engine either, but I want to be able to complete my project by noon tomorrow".

Is this as common as it appears?

yes, it's extremely common.
And the last few years it's getting ever worse, and seems to be coming more and more from people whose names and/or locations identify themselves as Indians.

They're basically only interested in getting a piece of paper showing themselves programmers, then cheating past a recruitment interview not much more involved than spelling out the word "computer", and then taking our jobs for their own.

But it's always been there, many kids have no idea what it takes to create software.
This is perfectly apparent from the many excuses they have for piracy, often hinging around "software costs only $1 for the CD".
They think writing something like Doom 3 or Photoshop takes a single person a few days at most, not realising it's teams of dozens or hundreds of people who need years.
And even if they did they don't know economics (never having had to pay the rent or bring in money to buy their own food and clothes) so they don't know what the cost of running such a team is.

Do your own homework, and stop bumping 3 year old threads with "gimme gimme gimme" :(

let me start by appologizing for stumbling across your forums and necroing a year old thread... but this is what you get for having the first search result in google! :P

anyway, im in a programming languages course at college and my instructor DOES NOT HAVE A DEGREE IN PROGRAMMING!!! what is wrong with the world today?
our next project is due in 1 week, we just got it extended from being due in 2 days because he has yet to mention building a compiler yet in class and that is what is our next project is!

im angry because i now have to explain passing by value vs passing by refference TO MY INSTRUCTOR OF A HIGH LEVEL PROGRAMMING COURSE!

this is stupid... :(
why did i pay for this? :(

this is stupid... :(

yeah

why did i pay for this? :(

Why would you pay for something stupid? Maybe you are stupid :P

I strongly condemn jwenting's post. Please don't just label as 'Indians' in general. For your kind information, it is Ramanujan's Mathematics, which stands as the base for Modern Computer Electronic Systems. I have great respect for Ramanujan, Ritchie, Gosling and for all those who contribute for the development of this e-world. Please think before you post.

@jwenting: I accept that the Education / Teaching standards or not as good when compared to western countries. But even then we learn and achieve. Think what if, if we get an education and guidance equivalent to the one in US and Canada.

Lolwut?

Ramanujan has practically nothing to do with computing. Maybe he devised a few quicker algorithms for computing pi.

I don't see a problem. jwenting clearly specified the context of posts on Daniweb from programmers who clearly don't want to put forth any real effort. He also made the observation that "more and more" of these posts are coming from members in India (according to their names and/or location). In my experience, that observation is accurate.

There was no generalization or racism, just a simple observation in a very specific context. I'm sorry you were offended, but the post you "condemn" is within the bounds of Daniweb's rules, which already makes provisions against racist remarks.

For your kind information, it is Ramanujan's Mathematics, which stands as the base for Modern Computer Electronic Systems.

So you're using Ramanujan's contributions to mathematics (note that he died in 1920) as an excuse for the current Indian CS educational system and apparent laziness of a statistically significant majority of students from that educational system who choose to post on Daniweb?

I accept that there are majority of such posts in Daniweb, of course that's the cause of our edu. standards, I accept that too. But I would like put the point that amidst this, there are people who really performs very well. I regret if I have hurt anybody.

Two good books that I have on my shelf are:

Crafting a Compiler, Fischer & LeBlanc
Compiler Design in C, Holub

Indeed, nobody claimed otherwise. As a prime example, our super moderator ~s.o.s~ is both a skilled programmer and from India.

Please don't take offense at this next statement as it's once again an innocent observation, but a common behavioral pattern of racists is seeing racism against themselves where none exists. You've shown such a pattern with this imagined offense against Indians, so rather than claiming racism in others, I'd suggest tolerance on your part first. Especially since it's so easy to misunderstand others on the web.

A degree does NOT == competence to teach a subject. I have no engineering degree (yet a lot of graduate level course studies), yet the IEEE recognizes me as an engineer due to my experience and accomplishments, AND I have taught software engineers with PhD's in the subject. In fact, I am the chairman of an IEEE affiliate organization. I have taught accredited courses in C++, wireless telephony, and networking to employees of AT&T. So, just because your teacher does not have a BS/MS/PhD (BS == Bull Stuff, MS == More of the Same, PhD == MS + Piled Higher and Deeper), does not mean they cannot teach you anything! Software that I designed and wrote currently runs about 80% of the semiconductor FAB's in the world, so if it is good enough for IBM, Motorola, Samsung, Philips, etc al...

FWIW, some of my most skilled software engineering colleagues are from India. There is no corner on the "market" for smarts. Just look at the accomplishments of such Indian scientific luminaries as:

Sir Chandrasekhara Venkata Raman - 1930 Nobel Prize for Physics (known for Raman scattering of radiation) and his nephew
Subrahmanyan Chandrasekhar, 1983 Nobel Prize for Physics, for whom the Chandrasekhara Limit is named for.

These are two people who were major influences on the careers of such as Einstein and Hoyle.
