few hours ago, i just attended my 1st meeting...
actually it was supposed to occur day before yesterday, but it occurred today bcoz NM(Network Management) postponed it...
anyway, Sami vai (my boss, student of Delhi IIT) told me to read some specifications of applications that NM built for their regular purpose. But as i am not good at reading :( I just go through them once, then I print them today.
Then when meeting starts Sami Bhai ask me a question "What kind of alarm?", I cant answer tht question(actually its not written in the specification), then he asked politely "tumi poro nai, vaia?", I replied - yes, I did, but I am not good at memorizing stuffs, then he told me politely "mone rakhte hobe je vaia".
After 4/5 min, he told me to note down important things about meeting, but then he found that I dont bring any pen & notebook, then he told me politely "next din theke pen & notebook niye ashbe...". In the middle of a meeting, he told me to write some things thn I used his pen to write!!!
Rizvi Bhai (The employee & also the giga boss of NM) is also a very nice person, he really welcomes me to GP & introduce me to other NM employees.
At the last of the meeting, Sami vai told tht as I'm fresh(which make me feel sooo good), I may ask Rizvi bhai a lot of questions, so from now, I hav to go to NM weekly for session & they will show me about the usage of their applications. so more to come, stay tuned...

MySQL, Java Connection
It may sound pretty dumb title, but I really faced some difficulties couple of days ago. Here I want to share about the problem I faced while connecting Java with MySQL.
I did tht when I did an "Interfacing" project in 4/1(4th year), but then I didn't face any probs, in fact it is still working in my PC, but one of my best friend Moni was facing a prob while connecting Java with MySQL. I tried a lot to fix the exception "Unexpected end of input stream", but I didn't get the prob bcoz the same code was working in my PC, but it wasn't in Moni's. Then I guessed "Is there any version conflict???"...
That day Moni was in my house with his laptop(HP), I tried & tried, he fell asleep, thn finally I cant fix it & he went to his home.
Then I thought I shud use a fresh PC(or OS) to test the prob, bcoz it was working in my PC, so I tried to solve it in WIN98!!! There is no service in win98, so how will i run MySQL, hmm pretty dumb prob, isn't it??? Then I found that in the bin folder of MySQL, the "mysqld.exe" works as a service, I clicked it & it continued running in background(remember - win98's ctrl+alt+del)!!! then i found tht its not working now...
after tht I googled for couple of hours to fix tht prob, but i was not getting any help, then I typed the "error message"(thts the way to search for a solution of a prob, I didn't know tht) & found the solution in several forums - yes, its a "version conflict". I'm using a driver (i.e. a jar file) for MySQL which is pretty old(3.x) & after 4.x its not backward compatible, they change the protocol of connection. And it was working in my XP bcoz MySQL version in XP was old(3.x), I took it (installed copy) from one of my closest frnd Ruman couple of years ago, as i dont hav installer of tht MySQL,I insatalled latest MySQL in win98, so does Moni, so we are facing tht exception.
So the conclusion is - there exists a version conflict in MySQL driver, Java & never use incompatible versioned driver, tools, api, etc ...
many thanks.
