Evening Sir. Happy Ugadi to you and your family members.. I believe in the things that what you say,sir.As a final year student of rhis college,i also want 
to be a good citizen and to relieve from this college with lot of potential to face the outer world.As a inspiration from you,we started that community.
But we could'nt get proper time to motivate the students on behalf of it.Lots of plans but lack of proper planning and time we couldnt.We dont want to 
leave it invain.For what purpose the community started should be fulfilled.For that we need your support,sir. Actually we planned to conduct various 
activities like group discussions,seminars,lectures,debates,entertaining events and alot during the weekends.But due to our project and NBA work we couldnt.
We'll definitely motivate our juniors.But we need proper guidance and support from your side,sir. Once again my wishes to you sir.

Hello sir

I am a former student of yours. I studied DS, UNIX shell and also came for 
GATE coaching. This year I completed my M.Tech from IITB. I am currently working
in NetApp bangalore.  We are having holidays from 25 th to 3rd jan. I wanted to
learn TCP/IP programming and Unix internals. Is it possible to complete any of
these courses in that one week :). If you are free then I will come to vizag for
that week and can attend the course at what ever the time convenient for you. I
can attend the course for longer hours at a stretch also.

If it is possible for you then can you please mention the fees and other
details for this type of course.

Regards and thanks
Rajesh Boppana

Hello Sir
Sorry for the delay in replying. I was quite busy last two weeks. My Elder sister (Second) got engaged and my eldest gave birth to a baby girl. I have resigned from my job last week at TCS and joined a new company Progress Software today. I visited the website.  There is lot of useful content specially for the BTech students. This is a the best way of sharing your knowledge.Let me know if I can be of any help in this regard. Thanks for the wishes. Yours Sincerely,Lavanya.

u.Everyday we recall u seeing some great people.I
always had a wish of becoming like u.The knowledge you
shared with us, and the time we spent in the class
.To tell you, i havent seen a great professor like u
till now in my journey of knowledge.WE MISS YOU.Sir
you might have a doubt that we(atlest i) are replying
u in this manner, just because you messaged us, but
thats not the case sir.We always wanted to be in touch
with you, also we were about to invite you into our
class group.Infact we never had the guts to approach
you thats the reason we didnt come to you, this is not
because that u scolded us or fear of punishment but we
feared just because we felt that we were not eligible
to meet you, as we couldn perform to your
expectations.Sir some things in life we get to know
later, this is just the case.There was no single
embedded systems class without remembering u.Sir i
used to tell my friends proudly that i am a student of
N.B.Venkateswarlu, the authoritatian of LINUX.Sir WE
MISS YOU.sorry for not letting out our feelings till

hope that i dont make any spelling mistakes!Sir its
actually our pleasure that we feel every time we say
that we have been taught by you sir.Everytime we say
that to someone it feels great sir.And sir everytime
you gave an assignment it was more of a challenge than
the regular assignments we get sir n we are what we
are today with even a little of useful knowledge
because of you sir but yes we were scared to sit in
your class sir and the two days you came were the days
of real test for us sir but now we see the difference
sir there is nobody who cares for us and we feel the
real pain sir.And one more thing to add up sir we all
loved you in our own way sir and we all are fortunate
enough that we got a chance to be taught by such a
person as you sir.Sir the situation here is as such
that PAVAN sir our super senior is coming to teach us
your subject sir the subject about which we only
imagined to be taught by you sir (Embedded Systems).We
are missing everything sir every moment of these last
days of college we are missing your presence.And sir
39 of our class students got placed in various

I passed out of GVP in 2002. Last January I met you to give my wedding invitation. Hope you remember me. I resigned TCS and came to Clemson University to do MS in computer engineering. I came here for spring 2007. I have been put up in Intelligent systems focus area. Here there are computer networking and computer architecture focus areas also... and I would like to choose some course from these areas also. Here are the courses in intelligent system focus area: 1. Introduction to robotics2. Intelligent robotic systems3. Image processing4. Machine vision5. Embedded computing6. Artificial intelligence7. pattern recognition8. neural networks In the above courses I would like to skip courses 1 & 2 and take the remaining. Because if I want to work on robotics, I need to take some course from Mechanical engg also.. Instead of taking new courses in mechanical, I thought it would be better to concentrate on image processing courses. Here are the course in Communication systems: 1. Computer communications2. Telecommunication network modelling and analysis3. Performance analysis of local computer networks4. Distributed computing and networks Here are the courses in Computer systems architecture 1. Computer architecture2. Computer system design and operation.3. Advanced topics in Computer architecture. I am planning to take some courses from intelligent systems and some from computer communications. Can you please suggest me courses from the above ones? Please advice me sir. Thank You,Harish.

I am Dinakar, your student. I studied in BVC engg. college(2003 batch), Amalapuram and my sister(Bhargavi Lakshmi) studied in Gayatri. Hope you remember me.

Currently I am working in CCIL and I am into production support. I wanted to be involved more into development. And here developement work is less, if not nothing. What I was told about my work during the interview process and even on first day of joining was different from the actual work I am getting. 

Now, I got an offer of 'Scientist-B' from Media Lab Asia . This is an R&D org. which used to be funded by MIT and Indian govt. Now, it is funded by Ministry of IT only and working on projects along with IITs(Mumbai, Delhi, Kanpur, Chennai). 

The mistake I did was, I didnot ask about the type of work that would be given to me during the time of interview. Now, when my friend(who also got selected) asked about the work, he was told "May be u r not interested in this organization, so u r asking too many questions". I am now confused about the type of work that would be given to me. 

Can u suggest me the right step in this regard. If u have anyone who's working/worked there, plz pass on their contact details. I have contacted some people from IIT Mumbai and I got good response about the projects, organization. Considering the projects going on, I am assuming the work will be good for me but a little bit risk is lying over here.
