Hi My name is K.S.Sreeram, and i am very much interested in contributing to the freebsd kernel. I have been browsing through the kernel code, but i was not able to follow it much, and i dont know where to begin, I would be happy, if somebody can help me through the process, as i feel confident, that i can contribute a lot, once i get started. I'll give you a little background about myself, as it might help you identify where i can fit in. I am 22yrs old, and i have been programming on the intel platform for the last 10 yrs. I have a reasonably good understanding of the intel architecture. I completed my B.Tech in computer science from the Indian Institute of Technology, Chennai in 2000. I'll list some of the things that i have worked on in the past. I have done a lot of system-level programming in MSDOS. - I have written several TSRs including one using which i implemented file and directory level access control - I have developed a complete 32 bit protected mode debugger, which loads directly off the boot sector of a floppy, which then boots MSDOS from the hard disk in virtual 86 mode. This project also involved writing an assembler and a disassembler for the 386 processor. - I have used the above debugger to hack around with a lot of other programs including DOS itself. I have also altered the behaviour of several programs in memory without altering the on-disk image. for instance, in many video games i changed the behaviour so that i wouldnt get killed!! - I have also used the above debugger, to detect a wide variety of DOS viruses, which typically occupy some amount RAM, and then fool DOS into thinking that this memory is actually used by the BIOS. - i have written code to directly use a floppy drive, without using the BIOS in protected mode. This involved a lot of hardware programming. - I have a reasonable amount of experience in writing a lot of both application level and system-level code for the win32 platform. - I have built a Pascal compiler as part of an assignment during school I have extensively worked on a lot of 3D graphics programming work - I have built a complete 3D game( actually 2.5D ) similar in functionality to the original Wolf3D, and have a lot of experience in writing optimized assembler code. - I have then worked on a full 3D engine, and have done some nice simulations of realtime shadows using raytracing. - I have built a interactive 3D world building program, which i used to build a reasonably detailed model of my school campus. Comparitively speaking i have lesser experience with Unix, which i have been using only for the last 1.5 yrs ( linux to begin with, and freebsd for the last one year ). I have a reasonably good understanding of the unix programming model, and its API. I have been reading up the following books off late (Author: Richard Stevens ) : - Unix network programming - TCP/IP Illustrated - Advanced Programming in the UNIX environment I am quite proficient in Intel Assembler, C, C++ and in Java. With this background information, i hope you will be able to help me in contributing to the freebsd kernel. The biggest problem is that i am not able to find enough documentation on the kernel Thanks & Regards Sreeram ( ks ) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
