Photography
I bought my first SLR, a Cannon Rebel 2000, in 2000 with a couple of
Amazon gift certificates. Sharad had graciously given me his $100
Amazon certificate ( imagine $100 for simply submitting our resumes
!!!) -- and so began my tryst with photography. Since then I've shot
over 350 rolls of film -- though I've been plannning for an online
gallery for the last two years I've never gotten over the inertia to
scan my favourite photos in. My favourite live subjects have been Medha
and Mugdha ( though neither of them like being the subject). Nowadays I
concentrate on black and white still life and many of my photos are
displayed in my living room. The photo on this page was taken at Sabino
Canyon.
Though I really like the Rebel, I'm a big fan on Ravi's Nikon N-65. I'm
convinced Nikon optics are an order better than the Cannon lenses I use
while the focussing and automation on the Cannon is better. Though I'm
totally averse to Photoshop touch-ups, I'm waiting for Medha to get her
digital SLR so I can play with a digital camera.
Cycling
I got a K2-Mach3 bike for my birthday this year. Its an amazing bike
and weighs about 20lbs. To find out more about this bike click here
here.
This bike is now my preferred mode of transportation and on weekends
the 30 mile rides (with the complementary spectacular
sunsets) are my favourite pastimes. For a
bike map of Tucson follow this

I bought my bike at
Supergo and
think they are a great bike shop. If you are looking for economical
bikes I strongly recommend Cycle Spectrum, great bikes at great prices.
Astronomy
Ravi and Medha bought me an 8" Newtonian for my birthday in 2002. This
has been my most prized possesion since then. I was a regular
star-gazer when Mugdha was here and our favourite spot was the Sabino
Canyon parking lot. Infact this hobby has been my most expensive and
had resulted in parking tickets. I've seen over 50 Messier objects
through my telescope and my favourites are M-57 ( ring nebula) and
M-13( Great Hercules Globular Cluster). My favourite constellation is
Cassiopeia and unsurprisingly Saturn and its rings are my favourite in
our solar system. I bought my telescope from
Starizona and definately recommend
their laser viewfinder ( a $70 add-on).
Radio Controlled Planes
Thanks to Mugdha,Radha et al. I got a Hobbyzone Aerobird for my
birthday last year. To find out more about this plane click
here.
I plan to put up a video with some fancy flying soon.
Sports
I have played several (Badminton, Tennis, Racquetball & Squash)
racquet sports at competition level but now play for the fun of it.
Hacking
Being around binaries has taken its toll and occasionally I like to
hack. Among the first masochistic things I did was in my second
semester in grad school -- Porting Linux onto the iPAQ H3600 in Fall
2001/Spring 2002. Nowadays there are dedicated
web-sites that serve as very
useful references. I also don't like the way coding conventions and
rules change for the Linux kernel. for example the system_call_table
structure is not exported in the recent Linux kernels claiming to be a
security risk, here is a trivial
hack which locates the
system call table and overrides the security acheived by hiding it
(assuming you have permissions to load kernel modules).
This spring(2004) I was doing research on ways to increase systems
security so needed malcode to evaluate the robustness we could impart.
To my surprise, while plenty of exploits were published on the
internet, relatively few succedeed in breaking into our target machine
(Pentium IV-3Ghz, Linux-2.4.22) -- it was easier for me to break the
systems by crafting synthetic attack code than tune available exploit
code. While writing attacks was fun, the scary part was that the simple
attacks we came up with were orders of magnitude more complex than what
is seen in malcode we got from the wild. At present my two pet projects
(which have taken the back-bench) are to get Darwin to compile and run
on an old Toshiba Pentium II - 266Mhz laptop and write programs for my
cellphones (Sony Ericsson T-68i and Sony Ericsson T-610).
