Primer to OpenSource Technologies and Programming in Linux Kernel
This Primer is an intensive hands-on workshop designed to teach experienced
programmers the Linux
Kernel Architecture. Upon completion of the workshop, participants will understand the
Linux
kernel architecture, memory management, modularization, and the layout of the kernel
source. They
will also have practiced key concepts and skills for development of character, block
and network
drivers. This is an intensive hands-on course designed to provide a detailed
examination of the
Linux kernel architecture including process scheduling, file systems and driving
peripheral
devices. Workshop is taught in a classroom with computers equipped with the current
Linux
distribution. This workshop provides hands-on training, concepts and demonstrations
with
emphasis on realistic labs and programming exercises.
Goal:
To build concepts and skills in Linux kernel essentials. Upon completion of workshop,
the
participants will feel comfortable modifying the Linux kernel to fit the needs of
their hardware
or applications, They will also have the tools necessary to port existing applications
and device
drivers to Linux, primarily from Unix-like systems.
Prerequisites:
Experience in C programming
Familiarity with basic tools such as vi, emacs, and file utilities.
Knowledge of systems programming in a Unix or Linux environment is a requirement;
register-level
hardware programming knowledge is preferable.
Understanding of basic Operating System concepts.
Some previous experience running Linux, compiling and installing kernels, etc.
Experience writing device drivers and kernel modules is not essential, but very
helpful.
Date/Duration:
Date:18th and 19th September
Workshop Start Time: 10:00 AM
Workshop End Time: 6:30-7:00 PM (depending on class progress)

Brief Background About the Instructor
He did his Masters in Computer Science from Indian Institute of Science (IISc),
Bangalore in 1997
(GATE topper) and Bachelors in Electronics Engineering from V. N. I. T., Nagpur
(formerly known as
V.R.C.E) again being a University topper.
Started his career at Veritas Software India in Veritas he worked on Filesystem and
replicated
filesystem design and development. He moved to United States in 1998 where worked with
Microsoft
in Windows NT/2000 Filesystem Group (Bellevue, WA). While at Microsoft, he developed
SWIG wrappers
for Win32Net APIs that allowed writing automated regression tests for windows
networking APIs in
Python and Perl. He also ported Samba to Windows 2000 and wrote user-space SMB clients
allow
scalability testing of Win2k File Server component under duress without having to rely
on
expensive hardware resources.
He joined Solution-Soft Systems in architectural role. He designed Safecapacity for
Solaris and
HPUX. Safecapacity monitors filesystems and free-space shortages and transparently
manages it by
compressing/migrating older files to overflow storage. Later he moved to Brocade
Communications.
There he worked on Advanced Zoning and developed several distributed components for
Brocade's
Fiber Channel switches.
Brief Background About the Organizers
Satyakam Goswami and Prateek Jaswant. They bring together more than 25 years of
experience between
them in software development, sales & development and IT consulting. purpose of
evangelizing the
concept of free source softwares and providing guidance and support in helping
organizations and
communities do that.
The first step in this direction is by organizing workshops and seminars in educating
people about
Linux and propagating the advantages of free source softwares. This workshop is a
beginning in
that direction. The participants mix will constitute members from corporates,
individual
consultants, members from the weaker societies and promising students.
Satyakam Goswami has 12 years of Industry experience in Internet and Open Source
technologies with
focus on Security right from the Operating System Kernel. He has been working closely
with Linux
Community for last 8 years, he believes in the use of GNU/Linux operating systems in
all walks of
Life, being the founder member of the Linux Users Group in Hyderabad. Recently, he was
also
associated with IIIT, Hyderabad as Sr. Research Engineer. He has contributed
immensely towards
the upliftment of society and in decreasing the digital divide. Currently Satyakam is
working on
using GNU/ Linux for the Building knowledge societies.
Prateek Jaswant has 14 years experience in support, sales and marketing products &
services
related to IT in India and the USA. He began as a Customer Support Engineer with a
