A Seminar like none!!

Day before yesterday was historic day, for I hosted 2 sesions back to back .
I started off with the "Introduction to Opensource" and "Introduction to
Solaris".I was using an Acer backed laptop which was running on Solaris
itself and one of my friend attending was quick to figure out that it
was NOT XP, this made the folks more curious and inquisitive. The
ambience suddenly changed and I could not help but stop the session  and
show them around a bit

Alas!! that system did not have compiz
installed on it , else we could have had more fun and given Vista a run
for its money!!!!!!

Anyway resuming the session there was another
stop, where I explained about Zones to the best of my understanding ,
from what I could see they were really interested in understanding how
it worked (especially when we were learning about virtualization in
one of the subjects).

I took this session for about an hr and once done told them that I had planned a demo and sure enough it had to be on Dtrace.

The
folks took a 15 min time out during which they started using the system
to execute unix commands that we were learning as a part of our
syllabus.(Thanks to our syllabus we have only UNIX theory this time and
practicals the next sem).

Then on everyone settled down for the
demo.I explained about the use of this debugging application as I
started the calculator application and ran Dtrace on that.

Initially
I coded to find out the total number of times each function executed
for the application to run and to perform simple calculation and for
the ctrl+alt+del folks this was something that they had never seen
before and couldnt help but look at it with awe!!!!!

In fact for the first time even I felt very very proud to be showcasing such stuff to the people.

Now
for the highlight.....Once again I wrote a few lines of code to find
out the time that each functions took to make the application
run!!!!!(and here is the surprise).

The output gave me some
erroneous time results that were definitely not right .I was delighted
to have found my first couple of bugs(or so I thought!!!!) then on I
fiddled around showing just how deep into the debugging aspect one can
go using Dtrace and finally finished it up after some hr and a half or
so!!

Later on I packed my bag and went back home and no sooner did I
reach than I filed a report of my findings to the BOSUG community
hoping to get the reply I was waiting for!!!

Alas... there came a
reply stating that such things happen and it has got nothing to do with
a bug and that everything was perfect.!!Turns out there are far more
intricate details that I was not aware of.!!!!Guess my happiness of
finding a bug need to wait a little longer

So there was the day I had and it was just amazing ,,huh!!!!!

I am keeping the post short , so that's it for now
